Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and in particular relates to an adjustable lever fork. Background Technology

[0002] The lever handle is used to control the opening and closing of doors and windows. It moves the internal lever structure by rotating or turning, thereby realizing the opening and closing of doors and windows. The lever is the core component of the lever handle.

[0003] The length of the handle fork for aluminum alloy windows varies depending on the product used (different thicknesses of the sash). For example, the handle fork length required for a 55mm thick casement sash is different from that for a 65mm thick casement sash.

[0004] As the number of projects increases, different window sashes require different lengths of adjustment forks, making distribution prone to errors. Furthermore, different sizes of doors and windows require different adjustment forks, resulting in poor versatility. Therefore, an adjustable adjustment fork is needed that can adapt to commonly available window sashes. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable shift fork to solve the problems existing in the prior art.

[0006] The objective of this utility model is achieved through the following technical solution: An adjustable shift fork includes a shift fork body and adjustment components, wherein two adjustment components are respectively located at two openings of the shift fork body; The adjustment assembly includes a U-shaped adjustment block and a locking pin. The U-shaped adjustment block is provided with a first rack. The two open ends of the shift fork body are respectively provided with adjustment grooves. The two sides of the adjustment groove are provided with second racks that mesh with the first rack. The U-shaped adjustment block is engaged with the shift fork body through the first rack and the second rack. The locking pin passes through the opening and adjustment groove of the U-shaped adjustment block.

[0007] Furthermore, the first rack is located on both sides of the opening of the U-shaped adjusting block.

[0008] Furthermore, the locking pin includes an abutment block, a stud, and a nut. The abutment block is located on the side of the shift fork body away from the U-shaped adjusting block, and the nut is located on the side of the U-shaped adjusting block away from the shift fork body. The size of the stud is smaller than the opening size of the adjusting groove and the U-shaped adjusting block, and the diameter of the nut is larger than the opening size of the U-shaped adjusting block.

[0009] Furthermore, gaskets are provided between the abutment block and the fork body, the nut and the U-shaped adjusting block.

[0010] Furthermore, the opening width of the U-shaped adjusting block is the same as the width of the adjusting groove.

[0011] The beneficial effects of this utility model are: It can adapt to the opening and closing of door panels of different thicknesses, improving the versatility of the lever fork.

[0012] It has a simple structure and is easy to adjust. Stability can be guaranteed by the meshing of the rack and pinion. Attached Figure Description

Detailed Implementation

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] See Figures 1-4 This utility model provides a technical solution: like Figures 1-4 As shown, an adjustable shift fork includes a shift fork body 1 and an adjustment component 2, with the two adjustment components 2 respectively located at two openings of the shift fork body 1; The adjustment assembly 2 includes a U-shaped adjustment block 21 and a locking pin. The U-shaped adjustment block 21 is provided with a first rack. The two open ends of the shift fork body 1 are respectively provided with adjustment grooves 12. The two sides of the adjustment grooves 12 are provided with second racks 25 that mesh with the first rack 11. The U-shaped adjustment block 21 is engaged with the shift fork body 1 through the first rack 11 and the second rack 25. The locking pin passes through the opening of the U-shaped adjustment block 21 and the adjustment grooves 12.

[0016] Through the above technical solution, the size of the fork body 1 is suitable for a 45mm thick window sash. By adding the adjustment component 2, the fork length of the fork body 1 can be increased, so that the fork body 1 can adapt to a 55mm or 65mm thick window sash.

[0017] When the shift fork body 1 needs to be used on a thicker window sash, the U-shaped adjusting block 21 is slid downwards to extend the length of the shift fork. Specifically, this downward sliding is achieved by the engagement of the first rack 11 and the second rack 25. After the distance is adjusted, the U-shaped adjusting block 21 and the shift fork body 1 are fixed by the locking pin. The engagement of the first rack 11 and the second rack 25 ensures that the locked U-shaped adjusting block 21 and the shift fork body 1 are stable and do not wobble.

[0018] Furthermore, the first rack 11 is located on both sides of the opening of the U-shaped adjusting block 21, and the corresponding second rack 25 is located on both sides of the adjusting groove 12, with the positions of the first rack 11 and the second rack 25 corresponding. Preferably, the opening width of the U-shaped adjusting block 21 is the same as the width of the adjusting groove 12.

[0019] Furthermore, the locking pin includes an abutment block 22, a stud 23, and a nut 24. The abutment block 22 is located on the side of the shift fork body 1 away from the U-shaped adjusting block 21, and the nut 24 is located on the side of the U-shaped adjusting block 21 away from the shift fork body 1. The size of the stud 23 is smaller than the opening size of the adjusting groove and the U-shaped adjusting block 21, and the diameter of the nut 24 is larger than the opening size of the U-shaped adjusting block 21.

[0020] With the above technical solution, the locking pin passes through one side of the shift fork body 1, causing the abutment block 22 to abut against the shift fork body 1. The stud 23 passes through the opening of the adjusting groove 12 and the U-shaped adjusting block 21, and is then threadedly connected to the stud 23 by the nut 24. By tightening the nut 24 and the stud 23, the U-shaped adjusting block 21 is fixed to the shift fork body 1 by the locking pin, preventing wobbling when rotating the shift fork. When it is necessary to adjust the length of the shift fork, the nut 24 can be loosened and the position of the U-shaped adjusting block 21 can be adjusted.

[0021] Furthermore, gaskets are provided between the abutment block 22 and the fork body 1, the nut 24 and the U-shaped adjusting block 21.

[0022] The above technical solution uses a shim to prevent slipping and provide protection, reducing the pressure on the shift fork body 1 and the U-shaped adjusting block 21 after tightening.

[0023] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
