[0025] In an embodiment of the present utility model, as Figure 1 、 2 shown, a linkage gear rack structure includes a fixed frame 1. The fixed frame 1 has a rectangular structure. A through accommodation groove 10 is provided inside the fixed frame 1. A gear 2 is provided in the accommodation groove 10. A part of the gear 2 extends out of the accommodation groove 10. Corresponding clamping shafts 4 are provided on the inner wall of the fixed frame 1. A through shaft hole 3 corresponding to the clamping shaft 4 is provided on the gear 2. The gear 2 is rotatably arranged on the clamping shaft 4.

[0026] Specifically, the fixing frame 1 is in the shape of a Chinese character "U" as a whole, and is provided with a receiving groove 10 which is arranged through the upper and lower parts thereof. At the same time, a clamping shaft 4 is symmetrically fixed on the inner side wall of the fixing frame 1. The gear 2 is arranged in the receiving groove 10, and an axial hole 3 which is arranged through and cooperates with the clamping shaft 4 is provided in the gear 2. The clamping shaft 4 extends into the axial hole 3, and the clamping shaft 4 is rotatably connected with the axial hole 3. The gear 2 can be limited by the cooperation between the fixing frame 1, the clamping shaft 4 and the axial hole 3. At the same time, the upper and lower parts of the gear 2 extend out of the receiving groove 10. The part extending above the gear 2 is convenient for cooperating with the other gears to drive the gear 2 to rotate, and the part extending below the gear 2 is convenient for meshing with the rack plate below.

[0027] The fixing frame 1 is symmetrically fixed with straight portions 5 extending outwards on both sides, and one end of the straight portion 5 away from the fixing frame 1 extends obliquely downwards to form an elastic portion 6, and one end of the elastic portion 6 away from the straight portion 5 is bent upwards to form a first abutting portion 7;

[0028] Specifically, the straight portion 5 extends outward from both sides of the fixing frame 1. After extending to a certain length, an elastic portion 6 arranged to be tilted downward is fixed to one end of the straight portion 5 away from the fixing frame 1. The elastic portion 6 is made of elastic plastic material and can be deformed under the action of external force. A first abutment portion 7 bent upward is fixed to one end of the elastic portion 6 away from the straight portion 5. The first abutment portion 7 is used to hook the middle rail, thereby limiting and fixing the entire gear frame structure.

[0029] Therefore, during the actual installation of the present application, the staff presses the elastic parts 6 on both sides inward by hand, and puts the fixing frame 1 into the through hole opened on the middle rail. Under the elastic force of the elastic part 6, the elastic part 6 is pressed against the edge of the through hole and under the elastic force, the first abutting parts 7 on both sides return to their positions and clamp the middle rail, which can greatly reduce the difficulty of installation, facilitate installation, and also ensure the stability of installation.

[0030] In this embodiment, the fixing frame 1 is made of elastic plastic material;

[0031] Specifically, during the installation of the gear 2 and the fixing frame 1, the fixing frame 1 can be slightly opened under the elastic force of the fixing frame 1 itself to expand the accommodating groove 10, and then the axial hole 3 on the gear 2 is matched with the clamping shaft 4 to achieve the installation limit between the gear 2 and the fixing frame 1.

[0032] In this embodiment, the clamping shaft 4 is provided with an inclined surface 11;

[0033] Specifically, during the installation of the gear 2, the fixing frame 1 can be slightly opened, and then the gear 2 is completely pushed into the receiving groove 10. During the pushing process, the gear 2 will contact the inclined surface 11 and, under the action of the slope of the inclined surface 11, the shaft hole 3 on the gear 2 will smoothly cooperate with the clamping shaft 4.

[0034] In this embodiment, the fixing frame 1 is integrally provided with the flat portion 5, and the upper surface of the fixing frame 1 is flush with the upper surface of the flat portion 5;

[0035] Specifically, the flat portion 5 is specifically extended outward from both sides of the fixing frame 1. Therefore, by integrally setting the fixing frame 1 and the flat portion 5, the stability of the entire structure can be improved. At the same time, in order to avoid interference during the sliding of the track, the upper surface of the fixing frame 1 is set to be flush with the upper surface of the flat portion 5.

[0036] In this embodiment, the elastic portion 6 is integrally provided with the first abutting portion 7, and the upper surface of the first abutting portion 7 is parallel to the upper surface of the flat portion 5;

[0037] Specifically, the elastic portion 6 and the first abutting portion 7 are integrally provided to improve the overall strength of the structure. And after the installation is completed, the first abutting portion 7 needs to hook the middle rail. Therefore, in order to improve the stability after installation, the upper surface of the first abutting portion 7 is set as a planar structure parallel to the upper surface of the flat portion 5, which can increase the contact area between the first abutting portion 7 and the middle rail and improve the structural stability.

[0038] As Figure 2 、 3 shown, in this embodiment, a side plate 8 extending downward is provided at the bottom of one side of the fixing frame 1, and a second abutting portion 9 bent toward the fixing frame 1 is fixedly provided at the bottom of the side plate 8;

[0039] Specifically, during the installation process, in order to further improve the stability of the structure, a side plate 8 can be provided below the fixing frame 1, and a second abutting portion 9 bent toward the fixing frame 1 is provided at the bottom of the side plate 8. During the installation process, the second abutting portion 9 can hook the lower surface of the rack plate to prevent the gear 2 from disengaging from the rack plate, and the side plate 8 is also supported by elastic plastic to facilitate the second abutting portion 9 to smoothly hook the rack plate.

[0040] In this embodiment, the second abutting portion 9 is provided on the side of the side plate 8 close to the gear 2;

[0041] Specifically, through the above setting, the interference of the side plate 8 on the meshing between the gear 2 and the rack plate can be avoided.

[0042] In this embodiment, the second abutting portion 9 is integrally provided with the side plate 8, and the upper surface of the second abutting portion 9 is parallel to the upper surface of the straight portion 5;

[0043] Specifically, the second abutting portion 9 is integrally provided with the side plate 8. In order to improve the overall strength of the structure, and after the installation is completed, the second abutting portion 9 needs to hook the rack plate. Therefore, in order to improve the stability after installation, the upper surface of the second abutting portion 9 is set as a planar structure parallel to the upper surface of the straight portion 5, which can increase the contact area between the second abutting portion 9 and the lower surface of the rack plate and improve the structural stability.

[0044] In summary, for the linkage gear rack structure in the above embodiment of the present invention, during actual installation, the staff presses the elastic portions 6 on both sides inward by hand and places the fixing frame 1 into the through hole opened in the middle rail. Under the elastic force of the elastic portions 6, the elastic portions 6 are squeezed and abutted against the edge of the through hole, and under the elastic force, the first abutting portions 7 on both sides are returned to clamp the middle rail tightly. This can greatly reduce the installation difficulty, facilitate the installation, and at the same time ensure the installation stability.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
