Description

Container room with fold open window

Technical Field

The invention relates to a container house, in particular to a container house with a folding window.

Background

The container house, also called container movable house, is reformed into house with door and window by using container as basic material.

The container house has the advantages of low transformation cost, high assembly speed, energy conservation, environmental protection, reutilization, no generation of building rubbish and the like. The container house is widely applied to the fields of field operation, building construction, large-scale factories and the like, and can be used as a dormitory and an office of field operation personnel, a dormitory, an office, a warehouse and a dining room of construction workers, and a dormitory, a dining room and a warehouse of factories. Due to the advantages of low transformation cost, high assembly speed and the like of the container house, the container house gradually appears in each large city and is used as a low-cost rental house. Moreover, as the container house has the advantages of energy conservation and environmental protection, reusability, no generation of building rubbish and the like, the 2011 Shenzhen great fortune meeting advocating the concept of 'green environmental protection, low carbon and energy conservation' also uses the container house to build additional places in the dragon sentry hall.

The window is the most main light transmission and ventilation structure of the container house. At present, the windows of the container rooms are mainly outwards split or stacked flat-open.

When the outward folio window is opened, the glass window is rotated outward and to the left and right sides. When the outward split type window is opened, on one hand, a certain space outside the window is occupied; on the other hand, when the window is opened, the window is turned to both sides of the window, thus blocking wind blowing from both sides of the window. Especially, in an environment where container rooms are built densely, the distance between the container rooms is relatively short, and the container rooms are used as a passage, when the container rooms are opened outwards, the container rooms occupy the space of the passage, so that normal passage of the passage is affected, for example, a pedestrian passes through the passage, and a glass window which is easy to open collides with the passage; and the dense container rooms are easy to form mutual blocking to cause air non-circulation, and the air non-circulation is aggravated because the blown wind from the two sides of the window is blocked when the outward opposite-opening window is opened. Therefore, in the prior art, the container house adopts the outward split type window, which not only occupies the space outside the window, but also has low ventilation efficiency.

The laminated casement window is characterized in that a plurality of glass windows are sequentially arranged when the window is closed; when opened, multiple glazings need to be laminated to allow for the passage of air. Although the laminated horizontal open type window cannot occupy the space outside the window and cannot block the wind on the two sides of the window, the laminated horizontal open type window occupies the space of the window in a large proportion, so that the window through which air enters and exits the container house is small. For example, a two-pane window has only one-half the size of the window when fully open. Therefore, the ventilation efficiency of the laminated casement window is very low.

Example one

Referring to fig. 1, a container house 10 with a folding window includes a house body 20 and a folding window 30 opened on the house body 20. Referring to fig. 2, the folding window 30 includes a window frame 40, an opening and closing mechanism 50, and a plurality of glass panes 60. The window frame 40 is fixed on the house body 20, and the plurality of glass windows 60 are respectively connected with the opening and closing mechanism 50. The opening and closing mechanism 50 is disposed on the window frame 40, and the opening and closing mechanism 50 is opened or closed along the window frame 40, so that the plurality of glass windows 60 are lowered along the window frame 40 and sequentially arranged to be closed or raised along the window frame 40 and opened in a stacked manner.

Referring to fig. 3, 4 and 5, specifically, the opening and closing mechanism 50 includes a plurality of rotating rods 70, a plurality of connecting rods 80 and a plurality of sliding connectors 90. The connecting rod 80 is connected with the glass window 60, the rotating rod 70 is rotatably connected with the connecting rod 80, and the two adjacent connecting rods 80 and the rotating rod 70 are respectively rotatably connected with the same sliding connecting piece 90. Specifically, the window frame 40 is formed with a sliding connection receiving groove 110. The sliding connector 90 is slidably engaged in the sliding connector accommodating groove 110.

Referring to fig. 2, in detail, the fold-open window 30 further includes a positioning and locking mechanism 500, and the positioning and locking mechanism 500 is disposed on the window frame 40 and used for locking or unlocking the opening and closing mechanism 50, so that the opening and closing mechanism 50 moves along the sliding connection receiving slot 110 or is fixed to the window frame 40.

Referring to fig. 5, in particular, the rotating lever 70 positioned at the uppermost end of the window frame 40 is also rotatably disposed on the window frame 40. The windowpane 60 positioned at the uppermost end of the window frame 40 is rotatably disposed on the window frame 40, and the windowpane 60 positioned at the uppermost end of the window frame 40 is also rotatably connected to the rotating rod 70 positioned at the uppermost end of the window frame 40 by a "V" shaped tension connection 120. The V-shaped expansion joint 120 is slidably engaged with the sliding-joint accommodating groove 110.

Referring to fig. 5, in detail, the window frame 40 includes two frames 130, a movable channel 140 is formed between the two frames 130, and the movable channel 140 is communicated with the sliding connection receiving slot 110. The two frames 130 are both provided with a sliding connection accommodating groove 110.

The operation of the container house 10 with the folding window of the present invention is explained below (please refer to fig. 1 to 5 together):

when the folding window 30 of the container house 10 having the folding window is in the fully closed state, the opening and closing mechanism 50 is opened to the limit along the window frame 40; at this time, the four glass windows 60 are sequentially arranged and closed to form a closed state of the windows (at this time, the opening and closing mechanism 50 is in a closed state); of course, the number of the glass windows 60 is not limited to four, and the present embodiment only takes four glass windows 60 as an example;

when the folding window 30 needs to be opened, the opening and closing mechanism 50 is unlocked through the positioning and locking mechanism 500, and the opening and closing mechanism 50 can slide along the sliding connection accommodating groove 110 after being unlocked; at this time, one glass window 60 at the lowermost end of the window frame 40 is pushed upwards, and the opening and closing mechanism 50 is lifted and closed along the window frame 40, so that the four glass windows 60 are driven to be opened in the direction far away from the window frame 40 at the same time; the three glass windows 60 at the lower end of the window frame 40 also rise simultaneously and approach to the glass window 60 at the uppermost end of the window frame 40, so that a lamination trend is formed; of course, the user can adjust the opening angle of the glass window 60 as desired;

it should be noted that, because the connecting rod 80 is connected with the glass window 60, the rotating rod 70 is rotatably connected with the connecting rod 80, and the two adjacent connecting rods 80 and the rotating rod 70 are respectively rotatably connected with the same sliding connection 90; therefore, in the process of opening the glass window 60, the connecting rod 80, the rotating rod 70 and the sliding connector 90 rise together along the sliding connection accommodating groove 110, and simultaneously the connecting rod 80 also rotates along the sliding connector 90, so that the glass window 60 is driven to open and rotate in the direction away from the window frame 40, and the glass window 60 is opened in the direction away from the window frame 40; it should be further noted that the opening and closing mechanism 50 of the fold-open window 30 of the present invention is tightly folded, so that the four glass windows 60 are tightly stacked together when fully opened, that is, the glass windows 60 can be opened to an angle close to 90 ° when fully opened; therefore, on one hand, the four glass windows 60 are laminated together to occupy small space when being fully opened, and on the other hand, the glass windows 60 are ensured not to block the ventilation of the windows when being fully opened, so that the ventilation efficiency of the laminated window 30 is ensured;

it should be noted that, if the container house 10 with the folding window of the present invention needs to reduce the occupied space outside the folding window 30, it is only necessary to reduce the height of the glass window 60 and increase the number of the glass windows 60. If the ventilation channel of the folding window 30 needs to be increased, only the number of the glass windows 60 and/or the width of the glass windows 60 need to be increased, and the height of the glass windows 60 does not need to be increased, so that the occupation of the space outside the folding window 30 is not increased, and the high ventilation efficiency of the folding window 30 is ensured;

it should be noted that, in the prior art, the accommodating groove of the window of the container room is transversely arranged with an upward opening; the window in the prior art is very easy to accumulate dust, and the accumulated dust is difficult to clean; in the container house 10 with the folding window of the present invention, the sliding connection accommodating groove 110 formed on the window frame 40 is a longitudinal sliding connection accommodating groove 110; the longitudinal sliding-coupling receiving groove 110 of the present invention is hardly deposited with dust and is convenient to clean, compared to the lateral receiving groove of the prior art.

Referring to fig. 2 and fig. 6, in the present embodiment, the positioning and locking mechanism 500 includes: a slide rail 510, a slide latch 520, and an unlocking assembly 530. The slide rail 510 is fixed to the window frame 40, and the slide locking member 520 is connected to the opening and closing mechanism 50. The slide rail 510 is provided with a slide groove 540, and the slide groove 540 is gradually narrowed from the groove bottom to the opening of the slide groove 540. The slide latch 520 has a snap-in portion 550 and a guide portion 560. The clamping portion 550 is slidably clamped in the sliding groove 540, and the clamping portion 550 is gradually narrowed from the bottom of the sliding groove 540 to the opening of the sliding groove 540. The guide portion 560 is pressed against the slide rail 510.

Referring to fig. 6 and 8, in detail, the unlocking assembly 530 includes: a locking piece 570, a mating ball 580, and a locking bar 590. The locking block 570 is a slanted block. The locking piece 570 is connected to the clamping portion 550. Specifically, the sliding lock 520 defines a lock passage 511, the engagement ball 580 is received in the lock passage 511, and the lock bar 590 is partially received in the lock passage 511.

Referring to fig. 8, 9 and 10, in particular, the locking rod 590 is used for providing a pushing force to the engaging ball 580, so that the locking block 570 and the engaging portion 550 are away from each other, and the locking block 570 and the engaging portion 550 are abutted against the inner sidewall of the sliding groove 540. Specifically, the locking bar 590 includes an operating end 512 and an acting end 513, the operating end 512 protruding from the sliding lock 520 along the locking passage 511, and the acting end 513 being received in the locking passage 511. The active end 513 has a conical adjustment portion 514 and a cylindrical locking portion 515, and a mating ball 580 abuts the conical adjustment portion 514 or the cylindrical locking portion 515.

Specifically, an arc-shaped protrusion 516 is disposed on the side of the locking channel 511 opposite to the engaging ball 580, and the arc-shaped protrusion 516 abuts against the conical adjustment portion 514 or the cylindrical locking portion 515. Specifically, the locking channel 511 is further provided with a limit stop 517, the locking rod 590 is provided with a limit engaging stop 518, and the limit engaging stop 518 is pressed against the limit stop 517 or separated from the limit stop 517. Specifically, the operating end 512 of the locking rod 590 is formed with a plurality of anti-slip grooves 519.

It should be noted that the working principle of the positioning and locking mechanism 500 of the present embodiment is described below (please refer to fig. 6 to fig. 10 together):

the positioning and locking mechanism 500 is arranged on the window frame 40 and used for locking or unlocking the opening and closing mechanism 50, so that the opening and closing mechanism 50 can move along the sliding connection accommodating groove 110 or be fixed with the window frame 40; in the present embodiment, the slide rail 510 is fixed to the window frame 40; the sliding locking piece 520 is clamped on the sliding rail 510 in a sliding way, and the sliding locking piece 520 is also fixedly connected with the sliding connecting block;

when the positioning and locking mechanism 500 is in the unlocked state, the opening and closing mechanism 50 and the window frame 40 slide relatively, and the glass window 60 can be opened or closed; at this time, the conical adjustment part 514 of the locking rod 590 abuts against the engaging ball 580 and the arc-shaped protrusion 516, respectively; it should be noted that the contact between the conical adjustment portion 514 and the engagement ball 580 and the arc-shaped protrusion 516 is relatively loose, and may be a state just contacting; at this time, the locking piece 570 is tightly connected with the sliding locking piece 520, and the sliding locking piece 520 and the locking piece 570 slide together along the sliding groove 540; it should be noted that, since the sliding locking piece 520 is connected to the sliding connection block, when the sliding locking piece 520 and the locking piece 570 slide along the sliding groove 540 together, the opening and closing mechanism 50 can be opened or closed along the window frame 40, and the opening angle of the glass window 60 can be adjusted along with the opening or closing of the opening and closing mechanism 50;

when the glass window 60 is opened to a desired angle or reaches a completely closed state, the state of the glass window 60 needs to be stably maintained (in this case, the positioning and locking mechanism 500 is in a locked state); at this time, the operation end 512 of the locking bar 590 is pressed by an external force, so that the locking bar 590 moves in a direction of entering the locking passage 511; in this process, the state in which the conical adjustment portion 514 of the locking bar 590 abuts against the engaging ball 580 and the arc-shaped protrusion 516, respectively, is transited to the state in which the cylindrical locking portion 515 of the locking bar 590 abuts against the engaging ball 580 and the arc-shaped protrusion 516, respectively; in the process, the locking rod 590 continuously presses the engagement ball 580 and the arc-shaped protrusion 516, thereby providing a pushing force to the engagement ball 580 to move the engagement ball 580 toward the inner sidewall of the sliding groove 540, thereby indirectly providing a pushing force to the locking piece 570 to move the locking piece 570 toward the inner sidewall of the sliding groove 540, i.e., the locking piece 570 and the sliding locking piece 520 are moved away from each other; the locking block 570 and the sliding locking piece 520 are far away from each other, so that the locking block 570 and the sliding locking piece 520 tightly abut against the inner side wall of the sliding groove 540 respectively; it should be noted that, at this time, the abutting degree of the locking block 570 and the sliding locking element 520 with the inner side wall of the sliding groove 540 is enough to make the locking block 570 and the sliding locking element 520 fixed relatively to the sliding rail 510;

it should be noted that the engaging ball 580 and the arc-shaped protrusion 516 form a guiding function for the conical adjusting portion 514 of the locking rod 590; thus, the configuration of the engagement balls 580 and the arcuate projections 516 in engagement with the conically shaped adjustment portion 514 of the lock bar 590 allows the lock bar 590 to smoothly and smoothly move further into the lock passage 511; in addition, the mutual engagement of the conical adjustment portion 514, the cylindrical locking portion 515, the engagement ball 580 and the arc-shaped protrusion 516 allows the locking bar 590 to smoothly and smoothly transition from a state where the conical adjustment portion 514 abuts against the engagement ball 580 and the arc-shaped protrusion 516, respectively, to a state where the cylindrical locking portion 515 abuts against the engagement ball 580 and the arc-shaped protrusion 516, respectively; the two states are smoothly and smoothly transited, so that the thrust provided by the matching ball 580 to the locking block 570 is uniformly changed, not instantaneous impact force, so that the holding between the locking block 570 and the sliding locking element 520 and the inner side wall of the sliding groove 540 is gradually changed from loose to tight, not instantaneous impact to the inner side wall of the sliding groove 540; due to the gradual and tight abutting, the damage to the sliding groove 540 is small, the sliding groove 540 is not easy to deform, and the damage to the matching ball 580 and the locking block 570 is also small, so that the service lives of all parts of the positioning and locking mechanism 500 are long, and the whole service life of the positioning and locking mechanism 500 is long;

when the opening angle of the glass window 60 needs to be adjusted again, the positioning and locking mechanism 500 needs to be changed from the locking state to the unlocking state; only external force is needed to act on the operation end 512, so that the locking rod 590 slides in the direction of getting out of the locking channel 511; in the process, the abutting between the locking block 570 and the sliding locking piece 520 and the inner side wall of the sliding groove 540 is gradually changed from tight abutting to loose abutting; namely, the state that the cylindrical locking part 515 is respectively abutted against the matching ball 580 and the arc-shaped protrusion 516 is transited to the state that the conical adjusting part 514 is respectively abutted against the matching ball 580 and the arc-shaped protrusion 516;

it should be noted that the sliding groove 540 is gradually narrowed from the groove bottom to the opening of the sliding groove 540; accordingly, the clamping portion 550 is gradually narrowed from the bottom of the sliding groove 540 to the opening of the sliding groove 540 and the locking block 570 is an inclined block; the clamping portion 550 and the locking block 570 are connected and then are clamped into the sliding groove 540 in a sliding manner, so that the clamping portion 550 and the locking block 570 can slide along the sliding groove 540 and cannot be separated from the sliding groove 540, and the stability of the system is improved; in addition, the guiding portion 560 is pressed on the sliding rail 510, and provides direction guidance for the clamping portion 550 and the locking block 570 when the clamping portion 550 and the locking block 570 slide along the sliding groove 540, so that the clamping portion 550 and the locking block 570 slide more stably;

it should be further noted that the locking passage 511 is further provided with a limit stop 517, and the locking rod 590 is provided with a limit engaging stop 518; the limit stop 517 and the limit matching table 518 are matched to prevent the locking rod 590 from entering the locking channel 511 after entering the locking channel 511 to a certain depth, so as to prevent the tip of the conical adjustment part 514 from frequently impacting the bottom of the locking channel 511 to deform or damage, and ensure the service life of the locking rod 590;

it should be noted that the operating end 512 of the locking rod 590 is provided with a plurality of anti-slip grooves 519, so that no slip is generated when the operating end 512 is operated by a human hand.

The fold-open window 30 of the present invention employs the positioning and locking mechanism 500 of the present embodiment, and the opening angle of the glass window 60 can be adjusted at will between 0 ° and 90 °, i.e. stepless adjustment of the glass window 60 is achieved, and flexibility is good.

the positioning and locking mechanism 600 is arranged on the window frame 40 and used for locking or unlocking the opening and closing mechanism 50, so that the opening and closing mechanism 50 can move along the sliding connection accommodating groove 110 or be fixed with the window frame 40; in the present embodiment, the slide rail 610 is fixed to the window frame 40; the sliding locking piece 620 is clamped on the sliding rail 610 in a sliding manner, and the sliding locking piece 620 is also fixedly connected with the sliding connecting block;

when the positioning and locking mechanism 600 is in the unlocked state, the opening and closing mechanism 50 and the window frame 40 slide relatively, and the glass window 60 can be opened or closed; at this time, the locking block 640 and the clamping part 680 tightly abut against each other, and the locking block 640 and the clamping part 680 slide along the sliding groove 660 together; it should be noted that, because the sliding locking piece 620 is connected with the sliding connection block, when the sliding locking piece 620 and the locking piece 640 slide together along the sliding groove 660, the opening and closing mechanism 50 can be opened or closed along the window frame 40, and the glass window 60 is adjusted in opening angle along with the opening or closing of the opening and closing mechanism 50;

when the glass window 60 is opened to a desired angle or reaches a completely closed state, the state of the glass window 60 needs to be stably maintained (in this case, the positioning and locking mechanism 600 is in a locked state); at this time, by screwing the action end 612 of the locking rod 650 (for example, screwing the action end 612 of the locking rod 650 in the counterclockwise direction), the locking block 640 gradually gets away from the clamping portion 680, so that the locking block 640 and the clamping portion 680 gradually and tightly abut against the inner side wall of the sliding groove 660; it should be noted that, by screwing the action end 612 of the locking rod 650 until the locking block 640 and the clamping portion 680 are far enough away from each other, the action end 612 is not screwed, that is, the locking block 640 and the clamping portion 680 are tightly abutted against the inner side wall of the sliding groove 660 enough to fix the locking block 640 and the clamping portion 680 relative to the sliding rail 610; it should be noted that when the distance between the locking block 640 and the clamping portion 680 is far enough, that is, the locking block 640 and the clamping portion 680 are tightly abutted against the inner sidewall of the sliding groove 660, so that the locking block 640 and the clamping portion 680 are relatively fixed to the sliding rail 610, the limit stopping table 617 and the limit matching table 618 are abutted against each other; at this time, the locking rod 650 cannot be screwed further in the counterclockwise direction, that is, the locking block 640 and the locking portion 680 cannot be separated further; thus, the separation degree of the locking block 640 and the clamping part 680 is ensured to be enough to enable the locking block 640 and the clamping part 680 to be relatively fixed with the slide rail 610, and meanwhile, the sliding groove 660 is prevented from being excessively expanded due to the excessive separation of the locking block 640 and the clamping part 680, the sliding groove 660 is prevented from being deformed, and the service life of the positioning and locking mechanism 600 is long; in addition, the locking block 640 is screwed with the locking rod 650, so that the abutting state of the locking block 640 and the clamping portion 680 and the inner side wall of the sliding groove 660 changes gradually from wide abutting to tight abutting, rather than the instant impact of the locking block 640 and the clamping portion 680 on the inner side wall of the sliding groove 660; due to the design, the damage to the sliding groove 660 is small, the sliding groove 660 is not easy to deform, and the damage to the locking block 640 and the clamping part 680 is small, so that the service life of each part of the positioning and locking mechanism 600 is long, and the service life of the whole positioning and locking mechanism 600 is long;

it should also be noted that the retaining end 614 of the lock bar 650 is provided with a retaining ring 621 that cooperates with the retaining ledge 619 of the second lock channel 611; thus, the locking rod 650 cannot be disengaged from the second locking channel 611, which ensures the connection between the locking block 640 and the clamping portion 680, and ensures good stability of the locking mechanism;

when the opening angle of the glass window 60 needs to be adjusted again, the positioning and locking mechanism 600 needs to be changed from the locking state to the unlocking state; it is only necessary to twist the action end 612 of the lock bar 650 again (it is necessary to twist the action end 612 of the lock bar 650 in a clockwise direction); in the process, the locking block 640 gradually approaches the clamping portion 680, that is, the supporting between the locking block 640 and the clamping portion 680 and the inner sidewall of the sliding groove 660 gradually changes from tight supporting to loose supporting or even to a separated state;

in addition, it should be noted that the guiding portion 690 is pressed on the sliding rail 610, and when the clamping portion 680 and the locking block 640 slide along the sliding groove 660, the guiding portion provides direction guidance for the clamping portion 680 and the locking block 640, so that the clamping portion 680 and the locking block 640 slide more stably;

in addition, it should be noted that the diameter of the connecting portion 616 of the locking bar 650 is smaller than the diameter of the threaded portion 615 of the locking bar 650, so that the connecting portion 616 of the locking bar 650 can smoothly pass through the first locking channel 670 and the second locking channel 611 in sequence, thereby facilitating the installation and removal of the positioning locking mechanism 600;

in addition, it should be noted that the first locking channel 670 and the second locking channel 611 are inclined from the locking block 640 to the direction close to the snap-in portion 680, so the locking rod 650 is also inclined from the locking block 640 to the direction close to the snap-in portion 680; the inclined design ensures that the locking block 640 and the clamping portion 680 are connected together through the locking rod 650, and also ensures that the acting end 612 of the locking rod 650 is in a position convenient for screwing, and meanwhile, the normal locking and unlocking of the positioning locking mechanism 600 are not affected; moreover, the locking block 640 has an inclined surface 622, and the inclined surface 622 is perpendicular to the locking rod 650, so that the locking rod 650 can be screwed conveniently, and the actual use experience is good;

in addition, it should be particularly noted that the threaded portion 615 of the locking rod 650 is screwed with the first locking channel 670, the diameter of the connecting portion 616 of the locking rod 650 is smaller than the diameter of the threaded portion 615 of the locking rod 650, the anti-drop ring 621 of the anti-drop end 614 is engaged with the anti-drop platform 619 of the second locking channel 611, the first locking channel 670 and the second locking channel 611 are inclined from the locking block 640 to a direction close to the clamped portion 680, the above structural designs are complementary and engaged with each other, and both the above designs ensure convenient assembly and disassembly of the structural components of the positioning and locking mechanism 600, ensure normal use and convenient use of the assembled structural components, and ensure long service life of the positioning and locking mechanism 600.

The fold-open window 30 of the present invention employs the positioning and locking mechanism 600 of the present embodiment, and the opening angle of the glass window 60 can be adjusted at will between 0 ° and 90 °, i.e. stepless adjustment of the glass window 60 is achieved, and flexibility is good.

EXAMPLE III

The container house 10 with the foldable window in this embodiment has the same structure except that the structure of the positioning and locking mechanism 700 is different from that of the positioning and locking mechanism 500 in the first embodiment, and thus, the description thereof is omitted.

Referring to fig. 2, 16 and 17, the positioning and locking mechanism 700 in the present embodiment includes: a slide rail 710, a slide latch 720, and an unlocking assembly 730. The slide rail 710 is fixed to the window frame 40. The sliding closure 720 is connected to the opening and closing mechanism 50. The outer side wall of the slide rail 710 is provided with a slide slot 740. The sliding locking member 720 has a locking protrusion 750, and the locking protrusion 750 is slidably locked in the sliding locking groove 740. Specifically, the slide rail 710 further has a slide groove 760, the slide locking member 720 has a clamping portion 770, and the clamping portion 770 is slidably disposed in the slide groove 760.

Referring to fig. 18, in particular, the unlocking assembly 730 includes: fitting 780, release lever 790 and adjustment lever 711. The clamping portion 770 and the mating member 780 form a first channel 712, a receiving groove 713 and a second channel 714 which are communicated in sequence. The unlocking lever 790 has an unlocking end 715 and a connecting end 716. The connecting end 716 is received in the receiving slot 713, and the unlocking end 715 passes through the first channel 712 and protrudes from the first channel 712. Adjustment rod 711 has an adjustment end 717 and a clamping end 718. The adjustment end 717 is received in the receiving groove 713. The connecting end 716 of the unlocking rod 790 is provided with a cylindrical connecting column 719, an inclined penetrating groove 721 is formed in the adjusting end 717 of the adjusting rod 711, and the cylindrical connecting column 719 is arranged in the inclined penetrating groove 721 in a penetrating manner.

Referring to fig. 16 and 18, in particular, the inner side wall of the sliding groove 760 is provided with a plurality of locking grooves 722, and the pressing end 718 of the adjusting rod 711 is received in the second passage 714 or protrudes from the second passage 714 and then extends into the locking grooves 722.

Referring to fig. 16 and 18, in detail, the adjusting rod 711 is sleeved with a return spring 723. The return spring 723 serves to provide an elastic restoring force to the adjusting lever 711 so that the pressing end 718 of the adjusting lever 711 has a tendency to protrude from the second passage 714 and protrude into the locking groove 722. Specifically, the second channel 714 is provided with a blocker ring 724. One end of the return spring 723 is connected to the pressing end 718 of the adjustment rod 711, and the other end abuts against the blocking ring 724.

Referring to fig. 16 and 17, specifically, the number of the sliding card slots 740 is two. Two sliding clamping grooves 740 are respectively formed on the outer side walls of the two sides of the sliding rail 710. The number of the latch protrusion strips 750 is two. The two clamping convex strips 750 are clamped into the two sliding clamping grooves 740 in the opposite directions in a one-to-one correspondence manner. Specifically, the first channel 712 and the second channel 714 are disposed perpendicular to each other.

The operation of the positioning and locking mechanism 700 of the present embodiment is described below (please refer to fig. 16, 17, and 18):

the positioning and locking mechanism 700 is arranged on the window frame 40 and used for locking or unlocking the opening and closing mechanism 50, so that the opening and closing mechanism 50 can move along the sliding connection accommodating groove 110 or be fixed with the window frame 40; in the present embodiment, the slide rail 710 is fixed to the window frame 40; the sliding locking piece 720 is clamped on the sliding rail 710 in a sliding way, and the sliding locking piece 720 is also fixedly connected with the sliding connecting block;

when the glass window 60 is opened to a desired angle or reaches a completely closed state, the state of the glass window 60 needs to be stably maintained (in this case, the positioning and locking mechanism 700 is in a locked state); at this time, the return spring 723 provides the adjusting lever 711 with an elastic restoring force, so that the pressing end 718 of the adjusting lever 711 protrudes from the second passage 714 and protrudes into the locking groove 722; thus, the clamping portion 770 is locked with the sliding rail 710 through the adjusting rod 711, that is, the clamping portion 770 is fixed relative to the sliding rail 710;

when the opening angle of the glass window 60 needs to be adjusted, the positioning and locking mechanism 700 needs to be changed from the locking state to the unlocking state; at this time, the unlocking end 715 of the unlocking rod 790 needs to be pressed toward the direction close to the first channel 712, because the connecting end 716 of the unlocking rod 790 is provided with a cylindrical connecting column 719, and the adjusting end 717 of the adjusting rod 711 is provided with an inclined penetrating groove 721, the cylindrical connecting column 719 is penetrated in the inclined penetrating groove 721; therefore, when the unlocking rod 790 slides to approach the first channel 712, the cylindrical connecting column 719 pushes the inclined penetrating slot 721 to move the adjusting rod 711 to approach the accommodating slot 713, so as to drive the pressing end 718 of the adjusting rod 711 to be disengaged from the locking groove 722 and to be accommodated in the second channel 714; at this time, the clamping portion 770 of the sliding locking member 720 and the sliding rail 710 can slide relatively, so as to unlock the positioning locking mechanism 700; in this state, the opening angle of the glass window 60 can be adjusted as needed;

when the glass window 60 is adjusted to a desired angle, the pressing of the unlocking end 715 of the unlocking lever 790 is released; at this time, due to the elastic restoring force of the return spring 723, the pressing end 718 of the adjusting lever 711 protrudes from the second passage 714 and protrudes into the locking groove 722; thereby realizing the relocking of the positioning and locking mechanism 700;

it should be noted that the locking of the positioning and locking mechanism 700 is achieved by the engagement of the pressing end 718 of the adjusting rod 711 and the locking groove 722 of the inner sidewall of the sliding groove 760; the locking grooves 722 are sequentially arranged on the inner side wall of the sliding groove 760, so that the adjacent two locking grooves 722 have a gap, and the gap is determined by the number of the locking grooves 722; therefore, the positioning and locking mechanism 700 is of a shift-position adjusting type, i.e. the foldable window 30 using the positioning and locking mechanism 700 of the present embodiment is of a shift-position adjusting type; one locking groove 722 corresponds to one locking gear; it should be noted that, the locking manner of the pressing end 718 and the locking groove 722 is very firm and has very good stability; of course, it should be noted that the locking groove 722 gradually widens from the inside to the opening, so that the pressing end 718 is accurately guided, so that the pressing end 718 accurately and smoothly extends into the locking groove 722, thereby further improving the system stability of the positioning and locking mechanism 700;

it should be noted that the adjusting rod 711 is provided with an elastic restoring force by the elastic restoring force of the restoring spring 723, so that the pressing end 718 of the adjusting rod 711 protrudes from the second channel 714 and extends into the locking groove 722 to achieve the automatic locking of the positioning and locking mechanism 700; the user can release his hand by simply pushing the glazing 60 to the desired opening angle; after the hands are released, the positioning locking mechanism 700 is automatically locked, so that the use is convenient and the operation is humanized;

it should be noted that the second channel 714 is provided with a blocking ring 724; one end of the return spring 723 is connected with the pressing end 718 of the adjusting rod 711, and the other end of the return spring abuts against the stop ring 724; thus, the blocking ring 724 provides a point of application for the return spring 723 to provide elastic restoring force for the pressing end 718 on the one hand; on the other hand, when the adjusting rod 711 slides to be close to the accommodating groove 713, the adjusting rod 711 is limited, so that the sliding of the adjusting rod 711 is more stable, and the stability of the positioning and locking mechanism 700 is further improved;

it should be further noted that the number of the sliding slots 740 is two, and the two sliding slots 740 are respectively formed on the outer side walls of the two sides of the sliding rail 710; correspondingly, the number of the clamping convex strips 750 is two, and the two clamping convex strips 750 are respectively clamped into the two sliding clamping grooves 740 in a one-to-one correspondence manner along opposite directions; due to the design, on one hand, the sliding locking piece 720 slides along the sliding rail 710, and on the other hand, the two convex strips apply force to the sliding rail 710 in opposite directions, so that the sliding locking piece 720 is firmly connected with the sliding rail 710 and cannot be easily separated from the sliding rail 710, and the system stability of the positioning locking mechanism 700 is further increased;

it should be noted that the first passage 712 and the second passage 714 are disposed perpendicular to each other, so that the unlocking lever 790 is parallel to the sliding groove 760; when the unlocking end 715 of the unlocking rod 790 is operated by a human hand, the sliding groove 760 just provides an avoiding position, so that the unlocking end 715 of the unlocking rod 790 is more convenient to operate.

Example four

In the container house 10 with the foldable window in this embodiment, except that the structure of the positioning and locking mechanism 800 is different from that of the positioning and locking mechanism 500 in the first embodiment, other structures are the same, and thus, the description thereof is omitted.

Referring to fig. 2, 19 and 20, the positioning and locking mechanism 800 in the present embodiment includes: a slide rail 810, a slide latch 820, and an unlocking component 830. The slide rail 810 is fixed to the window frame 40. The sliding closure 820 is connected to the opening and closing mechanism 50. The slide rail 810 is provided with a slide clamping groove 840, the slide locking piece 820 is provided with a clamping convex strip 850, and the clamping convex strip 850 is slidably clamped in the slide clamping groove 840. Specifically, the sliding rail 810 is further provided with a plurality of locking protruding columns 860, a locking slot 870 is formed between two adjacent locking protruding columns 860, and the locking protruding columns 860 are cylindrical.

Referring to fig. 21, in particular, the unlocking assembly 830 includes a mating member 880 and a locking bar 890. The fitting part 880 is connected to the sliding locking part 820, and the fitting part 880 is provided with a locking channel 811 extending through the fitting part 880.

With continued reference to fig. 21, in particular, the locking rod 890 has an active end 812 and a locking end 813. The action end 812 is connected with the locking end 813 through a connecting rod 816, and the connecting rod 816 is slidably arranged in the locking channel 811. Locking end 813 snaps into locking notch 870 or snaps out of locking notch 870.

With continued reference to fig. 19 and fig. 21, in detail, the unlocking assembly 830 further includes a return spring 814, and the return spring 814 is sleeved on the link 816. Specifically, the return spring 814 is coupled to the active end 812. Return spring 814 is adapted to provide a resilient return force to lock rod 890 such that lock end 813 has a tendency to return toward lock notch 870.

With continued reference to fig. 21, in particular, the mating member 880 is provided with a pair of orientation posts 815 that orient the pair of locking ends 813. The locking end 813 forms an "L" shaped structure with the link 816.

With continued reference to fig. 21, in particular, the active end 812 of the locking rod 890 is of a hemispherical configuration.

The operation of the positioning and locking mechanism 800 of the present embodiment is described below (please refer to fig. 19, 20, and 21):

the positioning and locking mechanism 800 is arranged on the window frame 40 and used for locking or unlocking the opening and closing mechanism 50, so that the opening and closing mechanism 50 can move along the sliding connection accommodating groove 110 or be fixed with the window frame 40; in the present embodiment, the slide rail 810 is fixed to the window frame 40; the sliding locking piece 820 is clamped on the sliding rail 810 in a sliding manner, and the sliding locking piece 820 is also fixedly connected with the sliding connecting block;

when the glass window 60 is opened to a desired angle or reaches a completely closed state, the state of the glass window 60 needs to be stably maintained (in this case, the positioning and locking mechanism 800 is in a locked state); at this time, the return spring 814 provides an elastic restoring force to the lock rod 890, so that the lock rod 890 is restored to the lock groove 870; i.e. such that locking end 813 of locking rod 890 is snapped into locking notch 870; thus, the locking block and slide locking element 820 is fixed relative to the slider; it should be noted that the fitting piece 880 is provided with a pair of orientation posts 815 for defining the directions of the locking ends 813, so that the locking ends 813 do not have direction deflection in the process of being released from the locking slots 870 or being clamped into the locking slots 870, thereby ensuring that the locking ends 813 are accurately clamped into the locking slots 870, and realizing accurate and stable locking of the positioning locking mechanism 800; it should be further noted that a locking slot 870 is formed between two adjacent locking projections 860, and the locking projections 860 are cylindrical; thus, in the process that the locking end 813 is clamped into the locking slot 870, the locking convex column 860 with a cylindrical structure also has a guiding function on the locking end 813, so that the locking end 813 is accurately and smoothly clamped into the locking slot 870; of course, the cylindrical locking boss 860 also allows the locking end 813 to be more easily removed when removing the locking notch 870;

when the opening angle of the glass window 60 needs to be adjusted, the positioning and locking mechanism 800 needs to be changed from the locking state to the unlocking state; at this point, force is required to be applied to the action end 812 of the lock bar 890 in a direction approaching the lock channel 811 to move the locking end 813 of the lock bar 890 in a direction away from the lock notch 870; thereby allowing locking end 813 to be disengaged from locking notch 870; meanwhile, the return spring 814 is compressed and deformed; after the locking end 813 is pulled out from the locking slot 870, the locking block and the sliding locking piece 820 slide relative to the sliding block, so as to unlock the positioning locking mechanism 800; in this state, the opening angle of the glass window 60 can be adjusted as needed;

when the window glass 60 is adjusted to the desired angle, the pressing of the action end 812 of the locking rod 890 is released; at this time, due to the elastic restoring force of the return spring 814, the locking end 813 of the locking rod 890 is clamped into the locking slot 870; thereby realizing the relocking of the positioning and locking mechanism 800;

it should be noted that the locking of the positioning and locking mechanism 800 is realized by the cooperation of the locking end 813 of the locking rod 890 and the sliding slot 840 of the sliding rail 810; the sliding clamping grooves 840 are sequentially arranged on the side wall of the sliding rail 810, so that a space is formed between every two adjacent sliding clamping grooves 840, and the size of the space is determined by the diameter of the locking convex column 860; therefore, the positioning and locking mechanism 800 is of a gear adjustment type, that is, the folding window 30 using the positioning and locking mechanism 800 of the present embodiment is of a gear adjustment type; one sliding clamping groove 840 corresponds to one locking gear; it should be further noted that the locking manner of the locking end 813 and the locking slot 870 is very firm and has very good stability;

it should be noted that the elastic restoring force of the restoring spring 814 provides the locking rod 890 with the elastic restoring force, so that the locking end 813 of the locking rod 890 is clamped into the locking notch 870 to achieve the automatic locking of the positioning and locking mechanism 800; the user can release his hand by simply pushing the glazing 60 to the desired opening angle; after the hands are loosened, the positioning locking mechanism 800 is automatically locked, so that the use is convenient and the operation is humanized;

it should be further noted that the locking end 813 and the connecting rod 816 form an "L" shaped structure, so as to ensure that after the locking end 813 is disengaged from the locking slot 870, the locking end 813 also supports the locking rod 890, and an avoiding groove is formed between the locking end 813 and the locking piece, so that the locking rod 890 successfully avoids the locking protrusion 860 through the avoiding groove, and the locking piece and the sliding locking piece 820 can smoothly slide along the sliding slot 840;

it should be further noted that the number of the sliding clamping grooves 840 is two, and the two sliding clamping grooves 840 are respectively formed on the outer side walls of the two sides of the sliding rail 810; correspondingly, the number of the clamping convex strips 850 is two, and the two clamping convex strips 850 are respectively clamped into the two sliding clamping grooves 840 in a one-to-one correspondence manner along opposite directions; the design allows the sliding locking member 820 to slide along the sliding rail 810, and allows the two protruding strips to apply force to the sliding rail 810 in opposite directions, so that the sliding locking member 820 is firmly connected to the sliding rail 810 and cannot easily disengage from the sliding rail 810, thereby further increasing the system stability of the positioning locking mechanism 800.

EXAMPLE five

In the container house 10 with the foldable window in this embodiment, except that the structure of the positioning and locking mechanism 900 is different from that of the positioning and locking mechanism 500 in the first embodiment, other structures are the same, and thus the description thereof is omitted.

Referring to fig. 2, fig. 22 and fig. 23, the positioning and locking mechanism 900 in the present embodiment includes: a slide rail 910, a slide latch 920, and an unlocking component 930. The slide rail 910 is fixed to the window frame 40. The sliding closure 920 is connected to the opening and closing mechanism 50. The slide rail 910 is provided with a slide groove 940, and the slide groove 940 gradually narrows from the bottom of the groove to the opening of the slide groove 940. The slide latch 920 has a snap-in portion 950 and a guide portion 960. The clamping portion 950 is slidably clamped in the sliding groove 940, and the clamping portion 950 is gradually narrowed from the bottom of the sliding groove 940 to the opening of the sliding groove 940. The guide portion 960 is pressed against the slide rail 910.

Referring to fig. 23 and fig. 24, the unlocking component 930 is disposed on the clamping portion 950, and the unlocking component 930 is used for unlocking or locking the sliding locking member 920, so that the clamping portion 950 slides along the sliding rail 910 or abuts against the sliding groove 940. Specifically, the clamping portion 950 is provided with an avoiding through hole 970 and a groove 980 communicated with the avoiding through hole 970.

Referring to fig. 24, 25 and 26, in detail, the unlocking assembly 930 includes: a locking rod 911, a locking block 912 and a return spring 913. The locking rod 911 is slidably disposed through the escape through hole 970. The locking piece 912 is slidably received in the groove 980. The locking bar 911 has an arc-shaped protrusion 914, and the arc-shaped protrusion 914 is received in the avoiding through hole 970 or received in the groove 980. The return spring 913 is fitted over the locking rod 911. The return spring 913 serves to provide an elastic restoring force to the locking lever 911 so that the arc-shaped protrusion 914 has a tendency to escape from the escape through hole 970 and enter the groove 980. The arc-shaped protrusion 914 is used to provide a pushing force for the locking block 912 to approach the inner sidewall of the sliding slot 940, so that the locking block 912 abuts against the inner sidewall of the sliding slot 940.

With continued reference to fig. 23 and 24, in particular, the direction of the groove 980 is perpendicular to the radial direction of the avoiding through hole 970. Specifically, the number of grooves 980 is two, and the locking bar 911 divides the two grooves 980 into four sub-grooves 915. The number of the locking blocks 912 is four, and the four locking blocks 912 are respectively accommodated in the four sub-grooves 915 and correspond to the four sub-grooves 915 one by one. Specifically, the number of the return springs 913 is two, and the two return springs 913 are respectively sleeved at two ends of the locking rod 911.

The operation of the positioning and locking mechanism 900 of the present embodiment is described below (please refer to fig. 22-26):

the positioning and locking mechanism 900 is arranged on the window frame 40 and used for locking or unlocking the opening and closing mechanism 50, so that the opening and closing mechanism 50 can move along the sliding connection accommodating groove 110 or be fixed with the window frame 40; in the present embodiment, the slide rail 910 is fixed to the window frame 40; the sliding locking piece 920 is clamped on the sliding rail 910 in a sliding manner, and the sliding locking piece 920 is also fixedly connected with the sliding connecting block;

when the glass window 60 is opened to a desired angle or reaches a completely closed state, the state of the glass window 60 needs to be stably maintained (in this case, the positioning and locking mechanism 900 is in a locked state); at this time, the return spring 913 provides an elastic restoring force for the locking rod 911, so that the arc-shaped protrusion 914 of the locking rod 911 escapes from the escape through hole 970 and enters the groove 980; thus, the arc-shaped protrusion 914 provides a pushing force to the locking block 912 to approach the inner side wall of the sliding groove 940, and the locking block 912 approaches the inner side wall of the sliding groove 940 and tightly abuts against the inner side wall of the sliding groove 940; it should be noted that, at this time, one side of the locking block 912 tightly abuts against the inner side wall of the sliding groove 940, and the other side tightly abuts against the arc-shaped protrusion 914; it should be noted that, the locking block 912 tightly abuts against the inner sidewall of the sliding groove 940, and the tightness is enough to make the locking block 912 and the inner sidewall of the sliding groove 940 relatively fixed;

it should be noted that, in the present embodiment, the locking rod 911 is provided with an elastic restoring force by the restoring spring 913 and the locking block 912 is provided with a pushing force approaching the inner sidewall of the sliding groove 940 by the arc-shaped protrusion 914; on one hand, the pressing state of the locking block 912 and the inner side wall of the sliding groove 940 changes gradually from loose pressing to tight pressing, but the locking block 912 does not impact the inner side wall of the sliding groove 940 instantly; so that the damage of the sliding groove 940 is small and the sliding groove 940 is not easy to deform; the damage of the locking block 912 is small, so that the service life of each part of the positioning and locking mechanism 900 is long, and the service life of the whole positioning and locking mechanism 900 is long; on the other hand, when the arc-shaped protrusion 914 enters the avoiding through hole 970, the arc-shaped protrusion 914 has a guiding function, so that the arc-shaped protrusion 914 can accurately and smoothly enter the avoiding through hole 970, thereby improving the system stability of the positioning and locking mechanism 900;

it should be further noted that, in the present embodiment, the number of the grooves 980 is two, and the locking bar 911 divides the two grooves 980 into four sub-grooves 915; the number of the locking blocks 912 is four, and the four locking blocks 912 are respectively accommodated in the four sub-grooves 915 and are in one-to-one correspondence with the four sub-grooves 915; due to the design, the pressing force on the inner side wall of the sliding groove 940 is divided into four parts on average and is also reduced to the inner side walls on two sides of the sliding groove 940, so that the stress on the inner side wall of the sliding groove 940 is more uniform, the sliding groove 940 is further ensured not to deform easily, and the service life of the positioning and locking mechanism 900 is further prolonged;

when the opening angle of the glass window 60 needs to be adjusted again, the positioning and locking mechanism 900 needs to be changed from the locking state to the unlocking state; at this time, only the end of the locking rod 911 needs to be pressed, so that the return spring 913 is compressed and deformed, and the arc-shaped protrusion 914 enters the avoiding through hole 970 from the groove 980; thus, the arc protrusion 914 is separated from the locking block 912, and the arc protrusion 914 no longer tightly abuts against the inner sidewall of the sliding groove 940; at this time, the sliding locking piece 920 can slide along the sliding groove 940, so as to unlock the positioning locking mechanism 900;

the fold-open window 30 of the present invention employs the positioning and locking mechanism 900 of the present embodiment, and the opening angle of the glass window 60 can be adjusted at will between 0 ° and 90 °, i.e. stepless adjustment of the glass window 60 is achieved, and flexibility is good.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
