Description

Technical Field

[0001] This utility model belongs to the technical field of disc spring supports and hangers, specifically relating to a disc spring support and hanger that prevents displacement. Background Technology

[0002] Disc spring supports bear the weight of pipes, equipment, etc., and evenly transfer their gravity to the supporting structure, ensuring the stability of the pipes and equipment and preventing deformation or damage due to their own weight.

[0003] Many existing disc spring supports are fixed with double nuts. Although this can achieve the purpose of fixing, the disc springs are easily affected by factors such as pipe vibration, water hammer effect or external impact in actual applications, which can cause them to loosen. This affects the buffer stroke of the disc springs and results in poor stability.

[0004] Therefore, a disc spring support bracket to prevent displacement was designed to overcome the aforementioned technical defects. Utility Model Content

Detailed Implementation

[0025] This specific embodiment is a disc spring support for preventing displacement, and its structural schematic diagram is shown below. Figures 1-6 As shown, it includes a base 1, a limiting plate 2 and a support beam 3 are fixedly connected to the top surface of the base 1, a top seat 4 is assembled on the upper side of the limiting plate 2 and the support beam 3, a screw 5 is threadedly connected to the top surface of the support beam 3, a through hole corresponding to the screw 5 is opened on the top surface of the top seat 4, a nut 7 is threadedly connected to the side wall of the screw 5, and a disc spring assembly is provided between the nut 7 and the top seat 4 on the side wall of the screw 5.

[0026] The screw 5 has a cavity 6 inside, and an anti-displacement component is installed inside the cavity 6.

[0027] The disc spring assembly includes a disc spring group 8 sleeved on the side wall of the screw 5. Washers 9 are respectively sleeved on the upper and lower sides of the side wall of the screw 5 at the disc spring group 8, and a bellows 10 is fixedly connected between the two washers 9. The disc spring group 8 can adopt existing technology, while the bellows 10 is made of rubber, which has good elasticity and is used to protect the disc spring group 8, keeping it in a sealed state and preventing it from being corroded by rain and snow during outdoor use, thus avoiding problems such as rusting and jamming.

[0028] like Figure 3 and Figure 6 As shown, the anti-displacement component includes a lead screw 11 rotatably connected to the inner wall of the cavity 6. The top end of the lead screw 11 passes through a screw 5. A threaded sleeve 12 is threadedly connected to the side wall of the lead screw 11. A connecting plate 14 is fixedly connected to the side wall of the threaded sleeve 12. A through groove 17 is opened on the side wall of the screw 5. The connecting plate 14 passes through the through groove 17. Positioning rods 15 are fixedly connected to the bottom surface of the connecting plate 14 away from the lead screw 11. A number of evenly distributed positioning holes 16 are opened on the end face of the nut 7. The positioning rods 15 are adapted to the positioning holes 16. The number of connecting plates 14 and through grooves 17 is at least four, and they are distributed in a ring array.

[0029] Specifically, in its initial state, the connecting plate 14 is located near the upper side of the cavity 6. During assembly, first select a suitable disc spring assembly 8 and put it on the screw 5. Then, insert the screw 5 into the screw hole at the top of the support beam 3 and tighten it. After tightening the nut 7 to a suitable tightness, control the positioning rod 15 to move downward and insert it into the appropriate positioning hole 16 to lock the nut 7. During long-term use, even if the nut 7 becomes loose, there will be no shaking or displacement, ensuring stability during use.

[0030] like Figure 4 As shown, an annular plate 18 is fixedly connected to the top surface of the upper washer 9, and a sealing cover 19 is provided on the top of the screw 5. The sealing cover 19 is threadedly connected to the annular plate 18. By providing the sealing cover 19, the screw 5 and nut 7 can be protected, and the structure on the screw 5 can be protected, effectively extending its service life.

[0031] like Figure 3 As shown, a storage groove 13 is provided on the top end face of the screw 5. An internal hexagonal plate is fixedly connected to the top of the lead screw 11, and the internal hexagonal plate is located in the storage groove 13 to serve as a storage function and save the top space of the screw 5.

[0032] Working principle: When supporting the pipeline, place the base 1 and the limiting plate 2 under the pipeline, and then place the top seat 4 on the upper side of the support beam 3. Then, screw the screw 5 through the through hole and screw it into the threaded hole on the support beam 3. Then tighten the nut 7 so that the disc spring assembly 8 is tightly attached between the top seat 4 and the nut 7. Then rotate the lead screw 11. The lead screw 11 drives the connecting plate 14 to move downward through the screw sleeve 12. The connecting plate 14 drives the positioning rod 15 to move downward so that it is inserted into the corresponding positioning hole 16 to lock the nut 7 and prevent the nut 7 from being displaced or loosened due to external force, thereby improving the stability during use.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
