Description

Novel detachable hinge

Technical field:

the utility model relates to the field of door and window hardware accessories, in particular to a novel detachable hinge.

The background technology is as follows:

at present, people use more detachable hinges and fixed hinges on doors and windows, and the fixed hinges cannot be detached after being installed and can only be detached, so that the fixed hinges are inconvenient to install after being detached, and therefore the use is less; the detachable hinge can be detached at any time according to the requirement after being installed, and the installation after detachment is much easier than that of the fixed hinge, so that the detachable hinge has wider application; however, the conventional detachable hinge also has certain disadvantages:

firstly, it is: because only one surface of the hinge plate of the traditional detachable hinge is provided with the countersunk head screw hole for installation, the hinge is forced to be divided into: the inner hinge, the outer hinge or the left hinge and the right hinge bring certain inconvenience to installation and purchase of the hinges.

Secondly, it is: because the upper hinge shaft and the lower hinge shaft of the traditional detachable hinge are equal in length, the center of the upper hinge sleeve is opposite to the center of the upper hinge shaft during sleeving, and the center of the lower hinge sleeve is opposite to the center of the lower hinge shaft at the same time, so that the upper hinge shaft and the lower hinge shaft can be sleeved at the same time, and one of the upper hinge shaft and the lower hinge shaft cannot be sleeved when being aligned with the other two; if one sleeve center is right opposite to the center of the hinge shaft and the deviation between the other sleeve center and the center of the hinge shaft exceeds half of the outer diameter of the sleeve, the door falls down and can only be sleeved with one hinge, and the door also has to be withdrawn and then re-sleeved, so that one person can not accurately consider the situation when sleeving the door, and the situation that the person cannot consider the situation and cannot consider the situation is always present, and the success of one-time sleeving is difficult; thus, not only is the operation of the suit in the initial installation difficult, but also the operation of the suit after the disassembly at ordinary times is difficult.

Thirdly, the method comprises the following steps: because the end heads of the hinge shafts of the traditional detachable hinges are flush, the allowable deviation value between the centers of the hinge sleeves and the centers of the hinge shafts is very small when the door is sleeved on the door frame, and in general, the inner diameter of the sleeve is 7.2 mm, the diameter of the hinge shaft is 7.0 mm, and the allowable deviation value is only one half of the diameter of the hinge shaft, namely 0.1 mm, of the inner diameter of the hinge sleeve, so that the center of the upper hinge sleeve is opposite to the center of the upper hinge shaft, the center of the lower hinge sleeve is opposite to the center of the lower hinge shaft, the deviation between the centers of the upper hinge sleeve and the lower hinge sleeve and the center of the hinge shaft can not be larger than 0.1 mm, and one of the upper hinge sleeve and the lower hinge sleeve is larger than 0.1 mm, and the two hinge sleeves can not be sleeved in when the door is sleeved on the door frame, and the door frame is new. Therefore, when a person is sleeved, the person is difficult to accurately consider both up and down, the situation that the person cannot take care of the person and cannot take care of the person always occurs, and the person is difficult to successfully complete the sleeving once; not only is the sleeving operation in the initial installation very difficult, but also the sleeving operation after the disassembly at ordinary times is very difficult.

Fourth, it is: because the sleeve hinge plate and the shaft hinge plate of the traditional detachable hinge are mutually overlapped, a tool is required to be used for shoveling a part which is the same as the hinge plate in shape and size and has a certain depth when the hinge is installed, and then the hinge plate is fixed in the installation groove by using a screw; if the mounting groove is not manufactured, the door gap is too large; making the mounting groove is laborious and time-consuming.

The utility model comprises the following steps:

aiming at the problems of the traditional detachable hinge, the utility model provides a novel detachable hinge, which is scientific, reasonable, simple, practical and more humanized in design and solves the problems of the traditional detachable hinge.

The specific technical scheme is as follows:

each pair of novel detachable hinge consists of an upper hinge shaft 1, a lower hinge shaft 2, a hinge shaft end 3, a shaft hinge plate 4, a sleeve 5, a sleeve hinge plate 6, countersunk screw holes 7, gaskets 8 and hinge sealing heads 9; a novel detachable hinge, a shaft hinge plate 4 and a sleeve hinge plate 6 are provided with countersunk screw holes 7 on both sides.

The effective length of the upper hinge shaft 1 of the novel detachable hinge is about 1.05 to 1.6 times of that of the lower hinge shaft 2 (or vice versa).

The hinge shaft end 3 of the novel detachable hinge is conical or hemispherical or truncated cone-shaped or the truncated cone-shaped end is connected with the hemispherical.

After a single hinge is inserted, the shaft hinge plate 4 and the sleeve hinge plate 6 are not at the same height; the shaft hinge plate 4 and the sleeve hinge plate 6 can freely rotate and are not overlapped and blocked; the thickness center line of the shaft hinge plate (4) in the horizontal direction is respectively perpendicular to and bisects the diameters of the upper hinge shaft (1) and the lower hinge shaft (2); the thickness center line of the sleeve hinge plate (6) in the horizontal direction is perpendicular to and bisects the diameter of the sleeve (5).

The novel detachable hinge has the advantages that the hinge end socket 9 is in a truncated cone shape or a hemispherical shape or a spherical segment shape.

The beneficial effects are that:

the novel detachable hinge is scientific, reasonable, simple, practical and humanized in design, solves the problems of the traditional detachable hinge, and is very simple, easy, time-saving and labor-saving no matter the novel detachable hinge is first installed or refitted or the detachable hinge is sleeved at ordinary times; after the hinge is installed, the difficult situation that the upper part and the lower part are difficult to be combined accurately can not occur any more, the operation of single person sleeving is very easy, and the success rate of one person sleeving can reach hundred percent.

Because the two sides of the shaft hinge plate 4 and the sleeve hinge plate 6 are provided with the countersunk screw holes 7, a pair of hinges can be arranged on the left side of the inward-opening door and the right side of the inward-opening door, and can be arranged on the left side of the outward-opening door and the right side of the outward-opening door; the left hinge, the right hinge or the inner hinge and the outer hinge are not separated; the hinge is suitable to be arranged on the left side or the right side of the door, and the inside or the outside of the door at will, so that the hinge can not be misplaced when the hinge is bought at will, and great convenience is brought to the installation and purchase of the hinge.

Because the effective lengths of the upper hinge shaft 1 and the lower hinge shaft 2 are unequal, a sleeve can be sleeved into a long hinge shaft first when the sleeve is sleeved, then another sleeve is sleeved into a short hinge shaft and falls under the condition that the sleeve is not separated from the long hinge shaft, the whole sleeving process is very simple, easy and easy to operate by one person, and the difficult situation that the conventional hinge with the detachable long shaft is difficult to take account of vertically and accurately is avoided, and the success rate of one-time sleeving operation by one person can reach hundred percent.

Because the end head of the hinge shaft is conical with strong centrality, the deviation between the center of the sleeve and the center of the hinge shaft during sleeving is not as accurate as that required by the traditional detachable hinge with the end head of the hinge shaft being flush; the traditional detachable hinge has the advantages that the ends of the hinge shafts are flush, so that the deviation between the center of the sleeve and the center of the hinge shaft can not be larger than 0.1 millimeter during sleeving, and the ends of the hinge shafts of the novel detachable hinge are conical, and the deviation between the center of the hinge shaft and the center of the sleeve can be sleeved as long as the deviation is not larger than the radius of the hinge shaft during sleeving; the diameter of the hinge shaft is 7 mm, the radius is 3.5 mm, compared with the hinge shaft with the conical end head and the parallel-level end head, the allowable deviation value between the center of the hinge shaft and the center of the sleeve is enlarged by 35 times when the hinge shaft is sleeved, so that when the hinge shaft is sleeved, firstly, the long shaft is sleeved firstly and then the short shaft is sleeved, the hinge shaft does not need to be sleeved up and down, and meanwhile, the end head of the hinge shaft is conical with strong centrality, so that the hinge shaft is not required to be aligned up and down very accurately, one person can easily deal with the hinge shaft, and the success rate of one-time sleeving can reach hundred percent.

The thickness center lines of the shaft hinge plates 4 in the horizontal direction are respectively perpendicular to and bisect the diameters of the hinge shafts 2 of the hinge shafts 1; the thickness center line of the sleeve hinge plate 6 in the horizontal direction is perpendicular to and bisects the diameter of the sleeve 5; in addition, the shaft hinge plate 4 and the sleeve hinge plate 6 are not at the same height, and the shaft hinge plate 4 and the sleeve hinge plate 6 are not overlapped after being installed; therefore, the procedure of cutting the mounting groove by a tool can be omitted when the hinge is mounted. After installation, the thickness center line of the sleeve hinge plate 6 in the horizontal direction coincides with the thickness center line of the shaft hinge plate 4 in the horizontal direction in a top view after closing the door, and the two hinge plates are on the same vertical plane.

Because the process of cutting the hinge mounting groove by the tool is omitted, the effects of time and labor saving are achieved, the damage to the door and the door frame is avoided, and after the door is refitted or reinstalled, the door and the door frame can not leave a gap with partial deletion, so that the integrity of the door and the door in appearance is maintained.

Description of the embodiments

Aiming at the problems of the traditional detachable hinge, the utility model provides a novel detachable hinge which is scientific, reasonable, simple, applicable and more humanized in design. The hinge comprises an upper hinge shaft 1, a lower hinge shaft 2, a hinge shaft end head 3, a shaft hinge plate 4, a sleeve 5, a sleeve hinge plate 6, a countersunk screw hole 7, a gasket 8 and a hinge end head 9.

Embodiments of the present utility model are described below with reference to the accompanying drawings:

in order to solve the problem that the conventional detachable hinge is divided into a left hinge and a right hinge or an inner hinge and an outer hinge due to the fact that only one side of the conventional detachable hinge is provided with countersunk head screw holes for installation, certain inconvenience is brought to installation and purchase, countersunk head screw holes 7 for installation are arranged on two sides of a sleeve hinge plate 6 and a shaft hinge plate 4, and the hinge is divided into the left hinge and the right hinge or the inner hinge and the outer hinge from the moment, as shown in fig. 10 and 11.

In order to solve the problem that the upper hinge shaft and the lower hinge shaft of the traditional detachable hinge are equal in length and inconvenient to assemble, the effective length of the upper hinge shaft 1 and the effective length of the lower hinge shaft 2 are designed to be unequal, and the effective length of the upper hinge shaft 1 is 1.3 times that of the lower hinge shaft 2, as shown in fig. 3 and 7. The sleeve may be nested into the long shaft before the sleeve is nested into the short shaft without the sleeve being separated from the long shaft, as shown in fig. 9.

In order to solve the problem that the deviation between the center of a sleeve and the center of a hinge shaft is required to be high when the hinge is sleeved because the end heads of the hinges of the traditional detachable hinge are in a flush shape, the shape of the end heads of the hinge shaft is designed to be conical with a strong centripetal function, as shown in fig. 3 and 7. The allowable deviation between the center of the hinge sleeve and the center of the hinge shaft is enlarged from 0.1 mm of the flush end to 3.5 mm of the conical end, as shown in fig. 12 and 13. The sleeving operation becomes very easy. The width of the grid in the figure represents the range of permissible values of the deviation between the center of the hinge sleeve and the center of the hinge shaft.

In order to simplify the installation operation of the traditional detachable hinge, the process of cutting an installation groove on a door and a door frame by using a tool is omitted, and the hinge is designed as follows: after the hinge is sleeved, the sleeve hinge plate and the shaft hinge plate are not at the same height, and the sleeve hinge plate and the shaft hinge plate can rotate freely and are not overlapped and blocked, as shown in fig. 10 and 11. The thickness center lines of the shaft hinge plates in the horizontal direction are respectively perpendicular to and divide the diameters of the upper hinge shaft and the lower hinge shaft in a flat mode, and the diameters are shown in fig. 4. The thickness centerline of the sleeve hinge plate in the horizontal direction is perpendicular to and bisects the diameter of the sleeve as shown in fig. 2. In the overlooking state after closing the door, the thickness center line of the sleeve hinge plate in the horizontal direction is mutually overlapped with the thickness center line of the shaft hinge plate in the horizontal direction, and the two hinge plates are positioned on the same vertical plane.

For the aesthetic appearance of the hinge, the hinge head retains the truncated cone shape of the conventional hinge, as indicated by reference numeral 9 in fig. 1.
