Description

Technical Field

[0001] This utility model relates to the field of flip-up door technology, specifically to a flip-up door mounting bracket. Background Technology

[0002] Mounting brackets are widely used in flip doors to connect and fix components. Flip doors are favored by private car owners due to their advantages such as quiet operation and environmental friendliness, leading to increasing market demand and higher requirements for the quality and performance of their mounting brackets. Existing mounting brackets mostly consist of two bases connected at an angle at the ends with connecting holes for welding or other methods of fixation, facilitating disassembly and replacement. However, they have several drawbacks. The metal base connection is susceptible to oxidation from cold and humid air, eventually cracking or even breaking. They also suffer from low strength and short lifespan, resulting in wasteful replacements. One-piece molded brackets, under different forces, may deform or break due to insufficient strength at the base connection, rendering the flip door unusable and threatening garage safety.

[0003] Chinese patent application CN203213832U discloses a mounting bracket for a flip-up door. This bracket features a unique design that enhances performance and reliability. The bracket body consists of a base one and a base two, angled at 90 degrees. Both bases include a bottom plate and side plates, providing a stable support frame. The base one has two strip-shaped mounting holes, and the base two has two strip-shaped mounting holes for connection and fixation to the flip-up door and other components. The key feature is the two reinforcing ribs at the corner of base one and base two, which are stamped from the outside in, with a "V"-shaped cross-section, forming a support surface between the bases. When the bracket is subjected to forces in different directions, such as the tension, pressure, and impact from the opening and closing of the flip-up door, the reinforcing ribs exert a tensile force on the inner surface, dispersing and balancing stress, preventing damage due to stress concentration at the corner, protecting the base connection structure, enhancing overall connection strength, ensuring the bracket's stability, maintaining the normal operation of the flip-up door, and extending its service life. However, in this prior art, if any base of the mounting bracket is damaged, the entire mounting bracket needs to be replaced, which makes the maintenance cost of the mounting bracket high.

[0004] Therefore, the mounting bracket needs to be improved to ensure the strength of the base while reducing the maintenance cost of the mounting bracket. Utility Model Content

[0005] To address the aforementioned issues, a hinged door mounting bracket is provided. This bracket comprises a first base, a second base, and a connector. The connector provides the connection strength between the first and second bases. Since the first and second bases are connected by the connector, if either the first or second base is damaged, only the opposite base needs to be replaced. This solves the problem in the prior art where the entire mounting bracket needs to be replaced if either base is damaged, resulting in high maintenance costs.

[0006] To address the existing technical problems, this utility model provides a hinged door mounting bracket, including a first base, a second base, and a connector; the connector is a right-angled triangle in the front view, and a first threaded hole is provided on the two right-angled sides of the connector; the first base and the second base are provided with a plurality of mounting holes; bolts are used to install the first base and the second base onto the two right-angled sides of the connector through the mounting holes and the threaded holes.

[0007] Preferably, the connector is provided with an angle adjustment mechanism; the adjustment mechanism includes an angle adjustment base, a limiting hole and a limiting rod; the angle adjustment base has a through hole; the limiting hole has a plurality of limiting grooves at equal angles along its circular edge; the limiting rod has a plurality of limiting blocks at equal angles along its circular edge; when the limiting rod passes through the through hole and is inserted into the limiting hole, the limiting blocks are inserted into the limiting grooves.

[0008] Preferably, the limiting block has a fixed insertion hole; a fixed insertion block is inserted into the fixed insertion hole; when the limiting rod is inserted into the through hole, the fixed insertion block is inserted into the fixed insertion hole, and at this time the limiting rod and the angle adjustment base are in a fixed connection state.

[0009] Preferably, the fixing block is provided with a handle for the operator to hold.

[0010] Preferably, the limiting rod is provided with a handle for the convenience of the operator.

[0011] Preferably, a height adjustment mechanism is provided under the angle adjustment base; the height adjustment mechanism includes a second threaded hole, a height adjustment base, and a threaded rod; the second threaded hole is radially opened on the angle adjustment base; a moving groove is opened on the height adjustment base; the angle adjustment base is slidably connected to the height adjustment mechanism through the moving groove, and the angle adjustment base moves along the moving groove; the threaded rod passes through the moving groove and is threadedly connected to the angle adjustment base through the second threaded hole.

[0012] Preferably, the top end of the threaded rod is provided with an anti-detachment block to prevent the angle adjustment base from detaching from the moving groove.

[0013] Preferably, the bottom end of the threaded rod is provided with a rotating block to assist the operator in rotating the threaded rod.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. In this utility model, the first base, the second base and the connector are connected by bolts. When the base is bent or broken, the easy disassembly of the bolt connection can be used to accurately locate the damaged base and remove and replace it separately without replacing the entire mounting bracket. This effectively reduces maintenance costs, reduces repair time and manpower consumption, improves the stability and reliability of the flip door system, and reduces the economic and usage burden caused to users by base damage.

[0016] 2. In this utility model, an angle adjustment mechanism is set on the connector. Through the cooperation of the limiting rod and the limiting hole, the relative angle between the connector and the base can be accurately determined and the connection can be made securely. Moreover, it is convenient to operate when the angle needs to be adjusted. It can effectively reduce the risk of component wear and failure caused by angle deviation, enhance the overall reliability and adaptability of the system, and enable the mounting bracket to better adapt to different installation needs and working conditions.

[0017] 3. In this utility model, a height adjustment mechanism is set under the angle adjustment base. The height of the angle adjustment base can be adjusted by rotating the threaded rod, thereby optimizing the spatial layout of the flip door, ensuring the accurate running trajectory of the door panel, reducing friction and jamming, improving the stability and reliability of the system, expanding the application range of the mounting bracket, enabling it to better cope with complex working conditions and site conditions, and enhancing its adaptability to different installation environments.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6 As shown: A hinged door mounting bracket includes a first base 1, a second base 2, and a connector 3; the connector 3 is a right-angled triangle in the front view, and a first threaded hole 31 is provided on the two right-angled sides of the connector 3; the first base 1 and the second base 2 are provided with a plurality of mounting holes; bolts are used to install the first base 1 and the second base 2 onto the two right-angled sides of the connector 3 through the mounting holes and the threaded holes.

[0027] In existing technologies, if any base of the mounting bracket bends or breaks, the entire mounting bracket needs to be replaced, resulting in high maintenance costs. To address this issue, this invention uses bolts to tightly connect the first base 1 and the second base 2 with the connecting component 3. The bolts pass through the mounting holes of the first base 1 and the second base 2 and are threaded into the first threaded hole 31 on the right-angle side of the connecting component 3, supporting the flap door. In the event of a base bending or breaking, the bolt connection allows for easy disassembly, enabling precise location and individual replacement of the damaged base without replacing the entire bracket. During maintenance, simply unscrew the corresponding bolts, remove the faulty base, replace it with the new component, and tighten the bolts to restore functionality. This design changes the traditional approach, reduces maintenance costs, minimizes repair time and manpower consumption, improves the stability and reliability of the flap door system, ensures long-term efficient operation, and alleviates the economic and operational burden on users caused by base damage.

[0028] Reference Figures 1-5 As shown: The connector 3 is provided with an angle adjustment mechanism 4; the adjustment mechanism includes an angle adjustment base 41, a limiting hole 42 and a limiting rod 43; the angle adjustment base 41 is provided with a through hole; the limiting hole 42 is provided with a plurality of limiting grooves 421 at equal angles along its circular edge; the limiting rod 43 is provided with a plurality of limiting blocks 431 at equal angles along its circular edge; when the limiting rod 43 passes through the through hole and is inserted into the limiting hole 42, the limiting block 431 is inserted into the limiting groove 421.

[0029] An angle-adjustable base 41 has a through hole to provide a passage for the limiting rod 43. Multiple limiting grooves 421 are distributed at equal angles along the circular edge of the limiting hole 42, and several limiting blocks 431 are correspondingly provided on the circular edge of the limiting rod 43. During installation, the limiting rod 43 is inserted into the limiting hole 42 through the through hole, causing the limiting blocks 431 to embed into the limiting grooves 421, accurately determining the relative angle between the connector 3 and the base and ensuring a secure connection. When angle adjustment is required, the limiting rod 43 is pulled out of the limiting hole 42, the connector 3 is rotated to the target angle, and then the limiting rod 43 is reinserted, causing the limiting blocks 431 to engage in the new limiting grooves 421 and secure them. The angle adjustment mechanism 4 effectively reduces the risk of component wear and failure due to angle deviation, enhancing the overall reliability and adaptability of the system.

[0030] Reference Figures 1-5 As shown: The limiting block 431 has a fixed insertion hole 432; a fixed insertion block 433 is inserted into the fixed insertion hole 432; when the limiting rod 43 passes through the through hole, the fixed insertion block 433 is inserted into the fixed insertion hole 432, and at this time the limiting rod 43 and the angle adjustment base 41 are in a fixed connection state.

[0031] When the limiting rod 43 passes through the through hole, the fixing block 433 inserts into the fixing hole 432. Through a tight fit and friction, the limiting rod 43 and the angle adjustment base 41 are firmly locked into a fixed connection. The fixing block 433 significantly improves the stability of the device connection, preventing the limiting rod 43 from loosening or shifting due to vibration or external forces during operation, thus ensuring a constant and precise relative angle of the base and providing stable support for the stable opening and closing of the flip door. When angle adjustment is required, the fixing block 433 is pulled out to unlock the connection, rotated for adjustment, and then inserted back into the fixing block 433 to secure it, ensuring that the mounting bracket can flexibly and precisely adapt to different working conditions.

[0032] Reference Figure 5 As shown: The fixed insert 433 is provided with a handle 4331 for the operator to hold.

[0033] The handle 4331 provides an application point for the operator, who can use the handle 4331 to pull the fixed plug 433 out of the fixed socket 432.

[0034] Reference Figure 5 As shown: The limiting rod 43 is provided with a handle 44 for the convenience of the operator.

[0035] In this flip-door mounting bracket, the handle 44 on the limiting rod 43 provides great convenience for the operator. When it is necessary to adjust the angle of the connector 3, the operator can easily pull out or insert the limiting rod 43 from the through hole and the limiting hole 42 by holding the handle 44, and then the angle of the connector 3 can be adjusted.

[0036] Reference Figure 5 and Figure 6 As shown: A height adjustment mechanism 5 is provided under the angle adjustment base 41; the height adjustment mechanism 5 includes a second threaded hole 51, a height adjustment base 52, and a threaded rod 53; the second threaded hole 51 is radially opened on the angle adjustment base 41; a moving groove 521 is opened on the height adjustment base 52; the angle adjustment base 41 is slidably connected to the height adjustment mechanism 5 through the moving groove 521, and the angle adjustment base 41 moves along the moving groove 521; the threaded rod 53 passes through the moving groove 521 and is threadedly connected to the angle adjustment base 41 through the second threaded hole 51.

[0037] The threaded rod 53 passes through the moving groove 521 and is threadedly connected to the second threaded hole 51. When the threaded rod 53 is rotated, the angle adjusting base 41 moves smoothly and directionally along the moving groove 521 due to the thread action, changing its height. During operation, based on the installation accuracy of the flip door, the flatness of the ground, and the compatibility requirements with surrounding facilities, rotating the threaded rod 53 drives the angle adjusting base 41 to rise and fall, adjusting the height of the base and connecting parts 3, optimizing the spatial layout of the flip door, ensuring accurate door movement trajectory, reducing friction and jamming, improving system stability and reliability, expanding the applicable range of the installation bracket, and enhancing adaptability to complex working conditions.

[0038] Reference Figure 6 As shown: The top end of the threaded rod 53 is provided with an anti-detachment block 531 to prevent the angle adjustment base 41 from detaching from the moving groove 521.

[0039] When the height of the angle adjustment base 41 is adjusted by rotating the threaded rod 53, the anti-detachment block 531 can effectively limit the displacement range of the angle adjustment base 41 in the moving groove 521, preventing it from accidentally detaching from the moving groove 521 due to excessive movement.

[0040] Reference Figure 6 As shown: The bottom end of the threaded rod 53 is provided with a rotating block 532 to assist the operator in rotating the threaded rod 53.

[0041] When the height of the angle adjustment base 41 in the height adjustment mechanism 5 needs to be adjusted, the operator rotates the threaded rod 53 using the rotating block 532. Through the rotation operation, the threaded rod 53 engages with the threaded engagement of the angle adjustment base 41, driving the base to rise and fall along the moving groove 521, thereby achieving fine adjustment of the height of the mounting bracket to adapt to the diverse installation needs, site conditions, and operating conditions of the flip door.

[0042] The hinged door mounting bracket mainly consists of a first base 1, a second base 2, and a connector 3. The connector 3 is a right-angled triangle with a first threaded hole 31 on its two right-angled sides. The first base 1 and the second base 2 have several mounting holes. Bolts are used to install the first base 1 and the second base 2 onto the two right-angled sides of the connector 3 through the mounting holes and threaded holes. If the base is bent or broken, the easy disassembly characteristic of the bolt connection can be used to accurately locate the damaged base and remove and replace it separately. The connector 3 is equipped with an angle adjustment mechanism 4, including an angle adjustment base 41, a limiting hole 42, and a limiting rod 43. The angle adjustment base 41 has a through hole. The limiting hole 42 has several limiting grooves 421 at equal angles along its circular edge. The limiting rod 43 has several limiting blocks 431 at equal angles along its circular edge. When the limiting rod 43 passes through the through hole and is inserted into the limiting hole 42, the limiting blocks 431 are inserted into the limiting grooves 421. To adjust the angle, the limiting rod 43 is pulled out, the connector 3 is rotated, and then it is reinserted and fixed. The limiting block 431 has a fixing hole 432, into which a fixing block 433 is inserted. When the limiting rod 43 passes through the through hole, the fixing block 433 is inserted into the fixing hole 432, preventing the limiting rod 43 from loosening or shifting. The fixed insert 433 is equipped with a handle 4331, and the limiting insert 43 is equipped with a handle 44 for easy operation. A height adjustment mechanism 5 is provided under the angle adjustment base 41, including a second threaded hole 51, a height adjustment base 52, and a threaded rod 53. The second threaded hole 51 is radially opened on the angle adjustment base 41. The height adjustment base 52 has a moving groove 521. The angle adjustment base 41 is slidably connected to the height adjustment mechanism 5 through the moving groove 521. The threaded rod 53 passes through the moving groove 521 and is threadedly connected to the angle adjustment base 41 through the second threaded hole 51. Rotating the threaded rod 53 can adjust the height of the angle adjustment base 41. An anti-detachment block 531 is provided at the top of the threaded rod 53 to prevent the angle adjustment base 41 from detaching from the moving groove 521, and a rotating block 532 is provided at the bottom to assist the operator in rotating the threaded rod 53.
