Description

Technical Field

[0001] This utility model relates to the field of fixed brackets, and in particular to a fixed bracket with an adjustable angle. Background Technology

[0002] A fixed support is a tool or device used to support, fix, install, and maintain the stability of equipment, structures, or objects. It plays an important role in many industries and applications, ensuring that equipment and components remain in a safe, stable, and precise position during operation. In the industrial and construction fields, fixed supports are commonly used to support and fix pipelines, ensuring that the pipelines remain stable during operation and preventing them from breaking or deforming due to external forces.

[0003] When fixing pipes with fixed supports, the pipes sometimes need to be tilted according to the installation requirements. However, the current fixed supports are mostly locked with bolts for adjustment. During adjustment, the bolts need to be tightened and loosened repeatedly. The bolts are prone to loosening after long-term wear. Under heavy loads, they are prone to loosening or displacement, which affects the reliability and safety of the support. To address this issue, we propose an adjustable-angle fixed support to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-angle fixed bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-angle fixed bracket includes two positioning mechanisms. Each positioning mechanism has an adjusting plate slidably connected inside. Bearings are fixedly embedded on the sides of the two adjusting plates that are close to each other. A rotating shaft is installed on the inner ring of each bearing. An adjusting seat is fixedly connected to the ends of the two rotating shafts that are close to each other. A fixing mechanism is fixedly connected to the upper surface of the adjusting seat. Ratchets are installed at the ends of the two rotating shafts that are far from each other. An opening is provided on the outer surface of each adjusting plate. A sliding plate is slidably connected inside the two openings. A locking mechanism is installed on the bottom surface of the sliding plate. Two pawls are fixedly connected to the upper surface of the sliding plate, and one end of each pawl engages with a ratchet.

[0007] In a further embodiment, the locking mechanism includes a fixed plate, both ends of which are connected to the outer surface of an adjusting plate. Two sliding holes are formed on the upper surface of the fixed plate, and a sliding rod is slidably connected inside each sliding hole. The top end of each sliding rod is connected to the bottom surface of the sliding plate. A first spring is sleeved on the outer surface of each sliding rod, the bottom end of each first spring is connected to the upper surface of the fixed plate, and the top end of each first spring is connected to the bottom surface of the sliding plate. A handle is fixedly connected to the bottom ends of both sliding rods.

[0008] In a further embodiment, the positioning mechanism includes a support tube, a second spring is fixedly connected to the inner wall of the support tube, a positioning hole is provided on the outer surface of the adjusting plate, and a positioning pin is provided on the outer surface of the support tube.

[0009] In a further embodiment, the fixing mechanism includes a first fixing seat and a second fixing seat. The bottom surface of the first fixing seat is connected to the upper surface of the adjusting seat. The second fixing seat has two fixing holes inside, and each fixing hole is slidably connected to a mounting bolt. The upper surface of the first fixing seat has two threaded holes.

[0010] In a further embodiment, anti-slip pads are fixedly connected to the inner walls of both the first fixing seat and the second fixing seat.

[0011] In a further embodiment, the bottom ends of the two positioning mechanisms are fixedly connected to a mounting base, and the upper surface of the mounting base has two mounting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a rotating shaft in conjunction with an adjusting seat, which allows the adjusting seat to rotate and adjust the angle in conjunction with the fixing mechanism. Ratchets are set at both ends of the rotating shaft. The ratchet can be locked in both directions by cooperating with two opposing pawls on the sliding plate. The mechanical interlock between the pawls and the ratchet, combined with the preload of the first spring and the locking mechanism, forms a double insurance, which can effectively prevent the bracket from being accidentally unlocked even under extreme loads, thus ensuring the safety of the fixed equipment.

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.

[0022] Please see Figure 1-4 In this utility model, an adjustable angle fixing bracket includes two positioning mechanisms 1. The positioning mechanism 1 includes a support tube 101. A second spring 102 is fixedly connected to the inner wall of the support tube 101. A positioning hole 103 is opened on the outer surface of the adjusting plate 4. A positioning pin 104 is provided on the outer surface of the support tube 101. A sliding opening adapted to the positioning pin 104 is opened on the outer surface of the support tube 101. The positioning pin 104 passes through the sliding opening on the support tube 101 and is inserted into the positioning hole 103, thereby positioning the adjusted adjusting plate 4.

[0023] Each positioning mechanism 1 has an adjusting plate 4 slidably connected inside. Bearings 12 are fixedly embedded on the sides of the two adjusting plates 4 that are close to each other. A rotating shaft 13 is installed on the inner ring of each bearing 12. An adjusting seat 10 is fixedly connected to the ends of the two rotating shafts 13 that are close to each other. The rotating shaft 13 cooperates with the bearing 12 to make the adjusting seat 10 rotate more smoothly, reduce wear, and extend its service life. A fixing mechanism 8 is fixedly connected to the upper surface of the adjusting seat 10. The fixing mechanism 8 includes a first fixing seat 801 and a second fixing seat 802. The bottom surface of the first fixing seat 801 is connected to the upper surface of the adjusting seat 10. Two fixing holes 8 are formed inside the second fixing seat 802. 05. Each fixing hole 805 has a sliding connection of a mounting bolt 804 inside. The upper surface of the first fixing seat 801 has two threaded holes 803. The pipe to be fixed is installed in the fixing mechanism 8. The mounting bolt 804 and the threaded holes 803 are used to fix the pipe to the first fixing seat 801 and the second fixing seat 802. The fixing mechanism 8 adopts a design with detachable mounting bolts 804 and threaded holes 803 to adapt to pipes or equipment of different sizes. The inner wall of the first fixing seat 801 and the inner wall of the second fixing seat 802 are fixedly connected with anti-slip pads 806. The anti-slip pads 806 protect the surface of the fixed object and prevent scratches or stress concentration.

[0024] Two rotating shafts 13 are each equipped with a ratchet 7 at their far ends. Each adjusting plate 4 has an opening 11 on its outer surface. A sliding plate 5 is slidably connected inside each of the two openings 11. A locking mechanism 9 is installed on the bottom surface of the sliding plate 5. Two pawls 6 are fixedly connected to the upper surface of the sliding plate 5. The pawls 6 and ratchet 7 are designed oppositely to ensure bidirectional locking of the rotating shaft 13. One end of each pawl 6 engages with the ratchet 7. The locking mechanism 9 includes a fixed plate 901. Both ends of the fixed plate 901 are connected to the outer surface of the adjusting plate 4. Two sliding holes 902 are opened on the upper surface of the fixed plate 901. A sliding rod 904 is slidably connected inside each sliding hole 902. The top end of each sliding rod 904 is connected to the bottom surface of the sliding plate 5. A first spring 905 is sleeved on the outer surface of each sliding rod 904. The bottom end of each first spring 905 is connected to the upper surface of the fixed plate 901. The top end of each first spring 905 is... Connected to the bottom surface of the sliding plate 5, the bottom ends of the two sliding rods 904 are fixedly connected to a handle 903. Pulling the handle 903 causes the sliding rods 904 to descend in conjunction with the sliding plate 5, causing the pawl 6 on the sliding plate 5 to disengage from the ratchet 7. This allows the adjusting seat 10 to adjust its installation angle according to the pipeline with the help of the rotating shaft 13. After adjustment, the first spring 905 returns to its original position in conjunction with the sliding plate 5, locking the pawl 6 and the ratchet 7 together. Through the interaction of the ratchet 7 and the pawl 6, stepless angle adjustment is achieved without the need to repeatedly tighten or loosen the bolts, making operation faster. After adjustment, the pawl 6 automatically locks the ratchet 7, and the first spring 905 of the locking mechanism 9 provides a stable locking force to prevent loosening or displacement under load, ensuring the reliability of the support. The bottom ends of the two positioning mechanisms 1 are fixedly connected to a mounting seat 3. The upper surface of the mounting seat 3 has two mounting holes 2, which provide a bottom fixing point. It can be quickly connected to the ground or a bracket through the mounting holes 2, making it suitable for various scenarios.

[0025] The working principle of this utility model is as follows:

[0026] In use, the fixed bracket is first fixed in the usage position by the mounting base 3. The pipe to be fixed is installed in the fixing mechanism 8. The first fixing base 801 and the second fixing base 802 are fixed to the pipe by the mounting bolt 804 and the threaded hole 803. By pulling out the positioning pin 104 on the positioning mechanism 1, the adjusting plate 4 can slide in the support tube 101. The adjusting plate 4 is adjusted to the corresponding height of the positioning hole 103. Then the positioning pin 104 is inserted to adjust the fixing mechanism 8 to a suitable height. Pulling the handle 903 drives the slide rod 904 to descend with the sliding plate 5, so that the pawl 6 on the sliding plate 5 disengages from the ratchet 7. The adjusting base 10 can be adjusted according to the installation angle of the pipe with the cooperation of the rotating shaft 13. After adjustment, the first spring 905 and the sliding plate 5 are reset, so that the pawl 6 and the ratchet 7 are locked together, thereby ensuring the safety of the fixed equipment.
