Abstract
Description
Technical Field
[0001] This utility model relates to the field of garage door bracket technology, specifically a high-strength safety bracket for garage doors. Background Technology
[0002] In the usage scenarios of garage doors, safety and stable operation are of paramount importance;
[0003] Traditional garage door support structures typically include a pair of guide rails, which are bolted to the support structure and fixed to the garage door and garage ceiling. However, these structures often have several drawbacks, making it difficult to meet the demands of high-intensity use. The overall structure of the support is simple and lacks effective anti-wear measures. When the garage door slides frequently on the roller guide rails, it easily causes wear on the guide rails and the garage door, shortening its service life and increasing maintenance costs. At the same time, some support structures have insufficient strength in their hanger structures, which are prone to deformation or even breakage when subjected to the weight of the garage door and the dynamic load during opening and closing over a long period of time, threatening the safety of the garage door. Utility Model Content
[0004] The technical problem this utility model aims to solve is that existing garage door brackets, which contain a pair of guide rails and are fixed to the garage door and ceiling by bolts and connecting brackets, have a simple structure but lack anti-wear measures and are prone to wear; the hanger strength is insufficient, and it is prone to deformation and breakage under long-term load and dynamic load, threatening the safety of use.
[0005] To solve the above problems, the technical solution adopted by this utility model is a high-strength safety bracket for garage doors, including a pair of roller guide rails. The inner side of the roller guide rails is fixed with an anti-wear pad by screws. The upper side of the roller guide rails is fixed with a hanger structure by screws. An auxiliary frame plate is fixed with screws at the bend of the roller guide rails. A connecting folding plate is fixed to one end of the auxiliary frame plate. The connecting folding plate is fixed to one side of the wall by bolts.
[0006] The hanger structure includes a triangular hanger fixed to the side of the roller guide rail. A right-angle connecting plate is fixed to the top of the triangular hanger by bolts. A pair of support connecting plates are fixed between the right-angle connecting plates at the top of two opposite triangular hangers by bolts. The support connecting plate at the top is fixed to the top of the wall by bolts.
[0007] As a further embodiment of this utility model, the lower end of the roller guide rail is fixed to the inside of the garage door frame by bolts to facilitate fixing its position.
[0008] As a further aspect of this invention, the anti-wear pad is made of rubber, and its surface is provided with regularly arranged concave and convex textures to further enhance the anti-wear effect and reduce the noise when the garage door rolls.
[0009] As a further embodiment of this utility model: the auxiliary frame plate and the connecting folding plate are integrally formed, and the auxiliary frame plate and the connecting folding plate are made of high-strength aluminum alloy with a thickness of 5-8mm, which reduces the overall weight while ensuring strength.
[0010] As a further embodiment of this utility model: each of the three corners of the triangular hanger is provided with a reinforcing rib, which is integrally cast with the triangular hanger. The width of the reinforcing rib is 3-6mm, so as to improve the load-bearing capacity and structural stability of the triangular hanger.
[0011] Compared with the prior art, the advantages of this utility model are as follows: Addressing the problem of simple structure and lack of wear-resistant measures in traditional brackets, this bracket features a rubber wear-resistant pad on the inner side of the roller guide rail with a regular textured surface. This effectively reduces wear on the garage door and guide rail, extends service life, reduces maintenance costs, and also reduces rolling noise. For the issue of insufficient strength and easy deformation and breakage of traditional bracket hangers, this bracket uses a triangular hanger with integrally cast reinforcing ribs at its three corners, improving load-bearing capacity and structural stability. Simultaneously, an integrally molded auxiliary frame plate and connecting folding plate made of high-strength aluminum alloy are added, reducing weight while ensuring strength.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.
[0021] Combined with appendix Figure 1 , 2 It can be seen that it includes a pair of roller guide rails 1. The inner side of the roller guide rails 1 is fixed with an anti-wear pad 2 by screws. The anti-wear pad 2 is made of rubber and its surface is provided with regularly arranged concave and convex textures to further enhance the anti-wear effect and reduce the noise when the garage door rolls. The lower end of the roller guide rails 1 is fixed to the inner side of the garage door frame by bolts to fix its position.
[0022] Combined with appendix Figure 1 , 2 4. It can be seen that a hanger structure is fixed to the upper side of the roller guide rail 1 by screws. The hanger structure includes a triangular hanger 5 fixed to the side of the roller guide rail 1. A right-angle connecting plate 6 is fixed to the top of the triangular hanger 5 by bolts. A pair of support connecting plates 7 are fixed between the right-angle connecting plates 6 at the top of two opposite triangular hangers 5 by bolts. The support connecting plate 7 at the top is fixed to the top of the wall by bolts. Each of the three corners of the triangular hanger 5 is provided with a reinforcing rib 5.1. The reinforcing rib 5.1 is integrally cast with the triangular hanger 5. The width of the reinforcing rib 5.1 is 3-6mm to improve the load-bearing capacity and structural stability of the triangular hanger 5.
[0023] Combined with appendix Figure 1 , 3 It can be seen that an auxiliary frame plate 3 is fixed to the bend of the roller guide rail 1 by screws.
