Detailed Description
Preferred embodiments of the present utility model will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, the present utility model provides a preferred embodiment of a hinge device.
A hinge device comprising a base 10, a first lever 21, a second lever 22, a third lever 23, and a fourth lever 24, and further comprising a first slider 31 and a second slider 32 slidably provided on the base 10; the first rod 21 is rotatably arranged on the first sliding block 31, the third rod 23 is rotatably arranged on the second sliding block 32, the second rod 22 is rotatably arranged on the base 10, the first rod 21 is rotatably connected with the second rod 22 and the fourth rod 24 respectively, and the fourth rod 24 is also rotatably connected with the third rod 23; the rotation axes of the first rod 21 and the first slider 31 are set as a point a, the rotation axes of the first rod 21 and the second rod 22 are set as a point B, the rotation axes of the second rod 22 and the base 10 are set as a point C, and an included angle formed by the point a, the point C and the point B is set as a first included angle; the first slider 31 and the second slider 32 move closer together when the hinge device is opened, and the first angle is smaller than 90 ° when the first slider 31 or/and the second slider 32 reach a limit position closer together.
Among them, a hinge device is a structure for door and window installation, allowing a door or window to be rotatably opened or rotatably closed while being opened and closed, and providing support and stability throughout the process. Specifically, the hinge device is provided at each of the upper and lower ends of the window main body, so that the door and window can be opened while being stable, and a sufficient supporting force is provided.
The node positions are defined, the connection positions of the first rod 21, the second rod 22 and the third rod 23 and the base 10 are respectively the point a, the point C and the point D, the connection positions of the first rod 21, the second rod 22 and the fourth rod 24 are respectively the point B and the point E, and the connection positions of the third rod 23230 and the fourth rod 24240 are respectively the point F. In the closed state of the hinge device, the first rod 21, the second rod 22, the third rod 23 and the fourth rod 24 are all folded into the base 10, particularly the first rod 21 and the second rod 22 are overlapped, the third rod 23 and the fourth rod 24 are also overlapped, and the first rod 21 is overlapped below the fourth rod 24, namely, the folding and closing of the door and window are realized. The first slider 31 and the second slider 32 are located away from each other, preferably at extreme positions of distance, i.e. point a and point D are located away from point C, and point B is located between point a and point C, and point E is located between point C and point F, as regards the positional relationship of point E and point F mainly with respect to the lengths of the third bar 23 and the fourth bar 24. In the opened state of the hinge device, the first, second, third and fourth bars 21, 22, 23 and 24 are disposed at an angle to the longitudinal direction of the base 10, and the points B, E and F are gradually apart from the base 10, and the first and second sliders 31 and 32 are slidably disposed close to each other, respectively.
The second rod 22 forms a second angle with the base 10, and the second angle is formed by the point a, the point B and the point C.
Specifically, in the closed state of the hinge device, the first included angle is a small angle, approaching 0 °, the first slider 31 and the second slider 32 are far away from each other when the hinge device is closed, and the first rod 21 and the second rod 22 are overlapped on the base 10, and the second included angle is in the range of 165 ° to 195 °. When the hinge device is opened slowly from the closed state, the first included angle expands along with the rotation of the first rod 21, the second rod 22 and the third rod 23, the angle of the first included angle gradually tapers to be larger, and the angle of the second included angle gradually tapers to be smaller until the hinge device is opened to the limit position, the first included angle becomes the largest angle, that is, the first included angle is smaller than 90 degrees when the first sliding block 31 or/and the second sliding block 32 approaches to the limit position, and the second included angle becomes the smallest angle, that is, the first included angle is smaller than 90 degrees when the first sliding block 31 or/and the second sliding block 32 approaches to the limit position.
First, when the first included angle is 90 °, the point B is at the outermost position, and the first included angle is changed from 90 ° to make the point B far away from the outermost position, i.e. the point B slides down to the left Cheng Huxian or slides down to the right Cheng Huxian, no matter the first included angle is increased or decreased. If the first angle is greater than 90 °, and the point B is on the right side of the outermost position, the second rod 22 is no longer used as a supporting structure for supporting the first rod 21, the force applied to the first rod 21 can only be received by the fourth rod 24, the force applied to the fourth rod 24 becomes very high, and the fourth rod 24 is used as a receiving structure for doors and windows, which is prone to shake without assistance of the second rod 22, especially in windy weather.
At the same time, the point B is located on the right side of the outermost position, which also causes the point E to return to the base 10, if the point E is not located at the outermost position before returning, the fourth bar 24 cannot move normally, or the second slider 32 needs to move back, so that the movement is blocked when the door and window are closed subsequently. If the E point is located at the outermost position before returning, the door and window will tilt to the right along with the fourth rod 24, so that the potential safety hazard is greater, and the subsequent window closing operation of the user is also not facilitated. Therefore, the first included angle is smaller than 90 degrees when the hinge device is opened to the limit state, and smoothness when the window is closed is improved.
Therefore, the first included angle needs to be smaller than 90 ° when the first slider 31 and/or the second slider 32 approach the limit position.
Therefore, in the design of the first included angle, the first included angle is smaller than 90 degrees when the first sliding block 31 or/and the second sliding block 32 are in contact with each other to reach the limit position, so that the stability of the hinge device is improved, and the vibration of the door and window in the opening state can be effectively reduced.
In this embodiment, referring to fig. 3 to 5, regarding the second included angle ranges from 165 ° to 195 ° in the closed state of the hinge device, normally, if the second included angle is 180 ° is a preferred choice, the first rod 21 and the second rod 22 can be better overlapped, stored on the base 10, and the opening, i.e., the rotation of the first rod 21 and the second rod 22, is also facilitated.
If the second included angle is smaller than 180 °, for example, between 180 ° and 165 °, the rotation axes of the first rod 21 and the second rod 22 will protrude outwards, and the actual position of the point B can be properly adjusted according to the positions of the point a and the point C, so as to satisfy the layout of the first rod 21 and the second rod 22 on the base 10, which is also a preferred choice.
And, if the second included angle is greater than 180 °, for example, between 180 ° and 195 °, the point B can be moved further toward the inner side of the base 10, thereby greatly reducing the space occupied by the hinge device when accommodated; meanwhile, when the hinge device is opened, the fourth rod 24 is forced to rotate and open, so that the outward thrust of the point B is given, and even if the second included angle is larger than 180 degrees, the point B can be moved outwards. The second included angle range is arranged in the closed state of the hinge device, so that the sealing condition of the door and window during closing is adapted, proper adjustment is performed, and the application range of the hinge device is improved.
Preferably, the second included angle ranges from 170 ° to 190 °. The angle range of the second included angle cannot be too small or too large, which is not beneficial to the storage of the hinge device, and is too large, which is not convenient for the initial movement of the first rod 21 and the second rod 22, because the point B moves outwards and the point A moves rightwards, two thrust forces can be received at the point B, and if the angle of the second included angle is too large, the point B can not move.
In this embodiment, a first limiting member or/and a second limiting member is fixedly disposed on the base 10, the first limiting member is disposed at the sliding stroke end of the first slider 31, and the second limiting member is disposed at the sliding stroke end of the second slider 32; wherein, the first slider 31 abuts against the first limiting member to limit when the hinge device is closed; or the second slider 32 abuts against the second limiting member to limit when the hinge device is closed.
When the hinge device is closed, the first slider 31 may contact the first limiting member to limit, or the second slider 32 may contact the second limiting member to limit, where the first limiting member and the second limiting member provide a limit at the end of the sliding stroke of the slider, so as to ensure that the slider stops moving at a specific position, thereby realizing stable closing of the hinge device, and further providing additional safety and stability, preventing the slider from exceeding a predetermined position, and protecting the integrity of the hinge device and related structures. Because the first slider 31 and the second slider 32 are linked, the related limiting function can be realized only by arranging the first limiting piece or the second limiting piece, and of course, the first limiting piece and the second limiting piece can be arranged, so that the integral integrity is further improved.
Meanwhile, the first limiting piece and the second limiting piece are arranged, so that the angle of the first included angle in the closed state of the hinge device is further limited. And, can set up adjustment mechanism to adjust the position of first locating part or/and second locating part on base 10, thereby adjust the angle of first contained angle, in order to satisfy the demand of different circumstances, improve hinge means's suitability.
As shown in fig. 6 and 7, the present utility model provides a preferred embodiment of the securing block 40.
A fixed block 40 is fixedly arranged on the base 10, the fixed block 40 is arranged between the first sliding block 31 and the second sliding block 32, and the second rod 22 is rotatably connected to the fixed block 40; and the first slider 31 and the second slider 32 move close to each other when the hinge device is opened, and the first slider 31 and/or the second slider 32 are/is abutted against the fixed block 40 at the limit position to realize limit.
The provision of the fixing block 40 brings the following advantages: first, the mounting is facilitated and the mounting and adjustment is facilitated, i.e., the second lever 22 is mounted to the fixed block 40, and the fixed block 40 is mounted to the base 10; second, the rotation bearing force is transferred, and the fixing block 40 can transfer the rotation bearing force of the second rod 22 to the fixing block 40, so that the base 10 is better protected, and the abrasion to the base 10 is reduced; third, the fixed block 40 can bear the abrasion brought by the second rod 22, and the service life of the hinge device is prolonged; fourth, by selecting the fixing blocks 40 of the corresponding thickness, the relative height of the second lever 22 can be appropriately adjusted, thereby enabling the hinge device to have a higher flexibility to fit the assembly requirements of other levers, such as the first lever 21, the third lever 23 and the fourth lever 24.
In this embodiment, the fixing block 40 further includes an anti-collision structure 50, and the anti-collision structure 50 includes anti-collision portions disposed at both end edges of the fixing block 40. Since the first lever 21, the second lever 22, the third lever 23, and the fourth lever 24 are in a interlocked relationship, the first slider 31 and the second slider 32 slide together toward the collision preventing portion of the collision preventing structure 50 or slide together away from the collision preventing member, and thus the movement of the first slider 31 and the second slider 32 is stopped as long as one collides with the collision preventing structure 50, and the collision preventing portions on both sides may be provided with one of them according to the sliding stroke of the first slider 31 and the second slider 32. Of course, in order to improve the overall stability, it is preferable that both the anti-collision parts are provided, and the first slider 31 and the second slider 32 are simultaneously buffer-protected, and the first slider 31 and the second slider 32 reaching the limit positions are also prevented from shaking, so that the stability of the door and window is improved. The anti-collision parts are respectively arranged at the two ends of the anti-collision structure 50, so that the structure is simplified, and the two anti-collision parts can mutually counteract the impact force transmitted from the two ends when striking the anti-collision structure 50, thereby improving the stability of the anti-collision structure 50; since the crash features 50 are provided with the fixed block 40, the stability of the fixed block 40 and the second lever 22 is improved.
Or provide another solution. The second rod 22 is rotatably disposed on the base 10, an anti-collision limiting structure is disposed between the first slider 31 and the second slider 32, and the first slider 31 and the second slider 32 move relatively when the hinge device is opened, and the first slider 31 and/or the second slider 32 are made to abut against the anti-collision limiting structure at a limit position so as to achieve limiting. The anti-collision limiting structure is independently arranged between the first sliding block 31 and the second sliding block 32, so that anti-collision buffering can be realized, and meanwhile, the interference to the second rod 22 is limited to be minimum.
As shown in fig. 6 to 8, the present utility model provides a preferred embodiment of the runner 11.
The base 10 is provided with at least one slideway 11, and the first slider 31 and the second slider 32 are both slidably disposed on the slideway 11.
Wherein the first slider 31 and the second slider 32 are preferably arranged in one slideway 11, providing a more stable and coordinated sliding movement for achieving a smooth opening and closing of the door and window. The fixed block 40 may be disposed in the slideway 11 or may be disposed outside the slideway 11.
In the present embodiment, the hinge device further includes a fifth lever 25, the fifth lever 25 being connected between the second slider 32 and the fourth lever 24, respectively, the third lever 23 being connected to an end of the fourth lever 24, the fifth lever 25 being connected to a non-end position of the fourth lever 24 for assisting rotation of the third lever 23 and the fourth lever 24, thereby restricting a rotation locus of the fourth lever 24.
