Description

Technical Field

[0001] This utility model relates to the field of folding door technology, specifically a folding door hinge mechanism. Background Technology

[0002] A folding door is a type of door that can be opened and closed by folding.

[0003] With the development of modern architectural design and home decoration, folding doors have been widely used due to their advantages such as saving space and being aesthetically pleasing. However, traditional folding door hinge mechanisms have many problems, such as the hinge pins being prone to wear, which can cause the folding door to become loose and wobbly. Therefore, it is necessary to develop a folding door hinge mechanism that is easy to use.

[0004] Chinese Patent Publication No. CN220565907U discloses "A Folding Door Hinge Structure", which includes a door body. The outer wall of the door body is provided with a connecting component, and the outer wall of the connecting component is provided with an installation component. The connecting component includes a fixing groove, and a fixing block is engaged with the inner wall of the fixing groove. A first bolt is provided on the outer wall of the door body. The folding door hinge structure is provided with a fixing groove, a fixing block, a first bolt, a lower base, a second bolt, an upper base, and a third bolt. The fixing block is engaged in the fixing groove to limit its position. The first bolt then fixes the fixing block to the door body, which can install the fixing block well. Even if the first bolt ages and gradually loosens, the fixing block will not fall off and render the folding door unusable, thus meeting people's needs. Both the lower base and the upper base are detachable, which facilitates the installation of the pivot and connecting seat.

[0005] The existing technology described above uses a fixing block that is snapped into a fixing groove to limit its position. The fixing block is then fixed to the door body with a first bolt, which ensures proper installation. Even if the first bolt ages and loosens, the fixing block will not fall off and render the folding door unusable, thus meeting people's needs. Both the lower and upper bases are detachable, facilitating the installation of the pivot and connecting seat. However, in the existing mechanism, the hinge is prone to wear during use, causing the folding door to loosen and wobble after prolonged use, which reduces the lifespan of the folding door to some extent. Utility Model Content

[0006] The purpose of this utility model is to provide a hinge mechanism for folding doors, so as to solve the problem mentioned in the background art that the hinge shaft is prone to wear, which causes the folding door to become loose and wobbly after long-term use, thus reducing the service life of the folding door to a certain extent.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a folding door hinge mechanism, including a connecting door panel, telescopic components are installed on both sides of the connecting door panel, and a hinge component is installed on the upper end of the telescopic components;

[0008] The telescopic assembly includes a sliding plate, the connecting door panel has a placement groove on one side of the sliding plate, a spring is installed in the placement groove, a moving block is installed on one side of the spring, a vertical rod is installed at one end of the moving block, a convex ball is installed at one end of the vertical rod, the sliding plate has a concave hole at the corresponding position of the convex ball, and a telescopic door panel is installed on one side of the sliding plate.

[0009] The hinge assembly includes a mounting block, a bolt is mounted on one side of the mounting block, a first gear is mounted on the upper end of the mounting block, a first connecting rod is connected to the upper end of the first gear, a second gear is mounted on the lower end of the first connecting rod, a second connecting rod is connected to the upper end of the second gear, and a third gear is provided on the lower end of the second connecting rod.

[0010] Preferably, the lower end of the telescopic door panel is equipped with multiple sets of omnidirectional wheels, and the sliding plate is also multiple sets, which are symmetrically arranged within the connecting door panel.

[0011] Preferably, there are multiple sets of placement slots, which are evenly and equidistantly arranged within the connecting door panel, and the moving block is slidably disposed within the placement slots.

[0012] Preferably, the vertical rod passes through the placement groove and extends to its outer side, and the convex ball matches the concave hole opened in the corresponding position of the slide plate.

[0013] Preferably, the telescopic door panel extends through the door panel and to its outer side, and the mounting block is detachably installed together with the telescopic door panel at its upper end by bolts.

[0014] Preferably, the first gear is rotatably mounted on the upper end of the mounting block, one end of the first connecting rod is rotatably connected to the first gear, and the other end of the first connecting rod is rotatably connected to the second gear.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] First, this utility model uses a hinge assembly to hinge the door panels together, reducing wear on parts and improving the service life of the folding door to a certain extent. When the telescopic door panel is folded, the movement of the telescopic door panel will drive the third gear to start rotating, and the rotation of the third gear will drive the second gear to rotate, which in turn will cause the first gear to rotate. With the orderly rotation of the third gear, the second gear and the first gear, the angle between the first link and the second link will change accordingly, making the folding process of the telescopic door panel smooth and convenient to operate.

[0018] Secondly, this utility model, through the telescopic component, facilitates the adjustment of the door panel width, improves flexibility, and moves the telescopic door panel. The movement of the telescopic door panel drives the sliding plate to move. The movement of the sliding plate presses the convex ball out of the concave hole. The movement of the convex ball drives the vertical rod to move. The movement of the vertical rod drives the moving block to move in the placement groove. The movement of the moving block causes the spring to compress. When it moves to the appropriate position, the convex ball is locked in the concave hole of the corresponding position of the sliding plate, limiting the position of the sliding plate.

Detailed Implementation

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-4A folding door hinge mechanism includes a connecting door panel 1, telescopic components 2 installed on both sides of the connecting door panel 1, and a hinge component 4 installed on the upper end of the telescopic components 2; the telescopic components 2 include a sliding plate 201, and the connecting door panel 1 has a placement groove 202 on one side of the sliding plate 201. A spring 203 is installed in the placement groove 202, a moving block 204 is installed on one side of the spring 203, a vertical rod 205 is installed at one end of the moving block 204, and a convex ball 206 is installed at one end of the vertical rod 205. The sliding plate 201 rests on the convex ball 206. A recessed hole is provided at the corresponding position of 06, and a telescopic door panel 207 is installed on one side of the sliding plate 201; the hinge assembly 4 includes a mounting block 401, a bolt 402 is installed on one side of the mounting block 401, and a first gear 403 is installed at the upper end of the mounting block 401. A first connecting rod 404 is connected to the upper end of the first gear 403, a second gear 405 is installed at the lower end of the first connecting rod 404, a second connecting rod 406 is connected to the upper end of the second gear 405, and a third gear 407 is provided at the lower end of the second connecting rod 406.

[0026] Through the above technical solution, the hinge assembly 4 is used to hinge the door panels together, reducing wear on parts and improving the service life of the folding door to a certain extent. When the telescopic door panel 207 is folded, the movement of the telescopic door panel 207 will drive the third gear 407 to start rotating. The rotation of the third gear 407 will drive the second gear 405 to rotate, which in turn will cause the first gear 403 to rotate. With the orderly rotation of the third gear 407, the second gear 405 and the first gear 403, the angle between the first link 404 and the second link 406 will change accordingly, so that the telescopic door panel 207... The folding process of the 7 is smooth and easy to operate. The width of the door panel can be easily adjusted by the telescopic component 2, which improves flexibility. Moving the telescopic door panel 207 causes the sliding plate 201 to move. The sliding plate 201 moves and presses the convex ball 206 out of the concave hole. The convex ball 206 moves and causes the vertical rod 205 to move. The vertical rod 205 moves and causes the moving block 204 to move in the placement slot 202. The movement of the moving block 204 compresses the spring 203. When it moves to the appropriate position, the convex ball 206 is locked in the concave hole of the corresponding position of the sliding plate 201, which limits the position of the sliding plate 201.

[0027] Specifically, the lower end of the telescopic door panel 207 is equipped with multiple sets of universal wheels 3, and there are multiple sets of sliding plates 201. The multiple sets of sliding plates 201 are symmetrically arranged within the connecting door panel 1.

[0028] Through the above technical solution, multiple sets of universal wheels 3 are installed at the lower end of the telescopic door panel 207 to facilitate the movement of the telescopic door panel 207. The sliding plate 201 is used to ensure the stability of the movement of the telescopic door panel 207. The sliding plate 201 is symmetrically arranged inside the connecting door panel 1 to facilitate the installation of the telescopic door panel 207 on both sides of the connecting door panel 1 and to facilitate adjustment.

[0029] Specifically, there are multiple sets of placement slots 202, which are evenly and equidistantly arranged within the connecting door panel 1, and the moving block 204 is slidably arranged within the placement slots 202.

[0030] Through the above technical solution, the evenly spaced placement slots 202 facilitate the installation of multiple sets of springs 203 and other parts, and facilitate the limitation of the movement position of the slide plate 201 to ensure stability.

[0031] Specifically, the vertical rod 205 passes through the placement groove 202 and extends to its outer side, and the convex ball 206 matches the concave hole opened in the corresponding position of the slide plate 201 on the convex ball 206.

[0032] With the above technical solution, when the telescopic door panel 207 is moved, the telescopic door panel 207 moves and drives the slide plate 201 to move. The slide plate 201 moves and presses the convex ball 206 to disengage from the concave hole. The convex ball 206 moves and drives the vertical rod 205 to move. The vertical rod 205 moves and drives the moving block 204 to move in the placement groove 202. The movement of the moving block 204 causes the spring 203 to be compressed, which facilitates the movement of the telescopic door panel 207.

[0033] Specifically, the telescopic door panel 207 extends through the door panel 1 and to its outer side, and the mounting block 401 is detachably installed on the upper end of the telescopic door panel 207 by bolts 402.

[0034] Through the above technical solution, the telescopic door panel 207 is connected through the door panel 1, so that the telescopic door panel 207 can freely extend and retract during movement. The mounting block 401 is detachably connected to the telescopic door panel 207 by bolts 402, which facilitates disassembly.

[0035] Specifically, the first gear 403 is rotatably mounted on the upper end of the mounting block 401, one end of the first connecting rod 404 is rotatably connected to the first gear 403, and the other end of the first connecting rod 404 is rotatably connected to the second gear 405.

[0036] With the above technical solution, the first gear 403 is rotatably set on the upper end of the mounting block 401, which provides a basis for power transmission. When the folding door is folded or unfolded, the external force will cause the telescopic door panel 207 to move, which will be transmitted to the first gear 403 to make it rotate. The first connecting rod 404 can conveniently connect the center end of the first gear 403 and the second gear 405.

[0037] Specifically, the first gear 403 meshes with the second gear 405, one end of the second connecting rod 406 is rotatably connected to the second gear 405, the other end of the second connecting rod 406 is rotatably connected to the third gear 407, and the lower end of the third gear 407 is rotatably connected to another set of telescopic door panels 207.

[0038] Through the above technical solution, the first gear 403 meshes with the second gear 405. The meshing relationship enables the power to be effectively transmitted between the two. When the first gear 403 rotates, it can precisely drive the second gear 405 to rotate through the contact between the teeth. During the folding process of the folding door, the rotational motion of the first gear 403 can be transmitted to the second gear 405 according to a fixed transmission ratio. One end of the second connecting rod 406 is rotatably connected to the second gear 405, and the other end is rotatably connected to the third gear 407. This allows the second connecting rod 406 to adapt to the changes in the positions of the second gear 405 and the third gear 407, so that the three gears can work together to transmit the motion of one telescopic door panel 207 to another telescopic door panel 207, thereby realizing the overall folding or unfolding action of the folding door.

[0039] In use, when the telescopic door panel 207 needs to be folded, the telescopic door panel 207 moves, causing the third gear 407 to start rotating. The rotation of the third gear 407 drives the second gear 405 to rotate, which in turn causes the first gear 403 to rotate. With the orderly rotation of the third gear 407, the second gear 405 and the first gear 403, the angle between the first connecting rod 404 and the second connecting rod 406 will change accordingly, making the folding process of the telescopic door panel 207 smooth and easy to operate. When the door panel width needs to be adjusted, the telescopic door panel 207 is moved. The movement of the telescopic door panel 207 causes the slide plate 201 to move. The movement of the slide plate 201 presses the convex ball 206 out of the concave hole. The movement of the convex ball 206 causes the vertical rod 205 to move. The movement of the vertical rod 205 causes the moving block 204 to move in the placement groove 202. The movement of the moving block 204 causes the spring 203 to be compressed. When it moves to the appropriate position, the convex ball 206 is locked in the concave hole of the corresponding position of the slide plate 201, limiting the position of the slide plate 201.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of this application. The scope of this application is defined by the appended claims and their equivalents.
