Description

Technical Field

[0001] This utility model relates to the field of spring supports, and in particular to a flat constant force spring support bracket. Background Technology

[0002] Constant force spring supports are used to stabilize pipes or equipment suspended and supported by constant force springs within a specified load displacement range, ensuring that the applied load torque is always balanced with the spring torque generated inside the constant force spring. When thermal displacement occurs, regardless of whether the thermal displacement increases, decreases, or disappears, they can always obtain a constant supporting force, thereby avoiding major equipment accidents.

[0003] Existing constant force spring supports will age and other conditions after long-term use. In order to ensure the stable use of spring supports, it is necessary to be able to adjust and correct the spring supports to ensure the stable elastic coefficient of the constant force spring supports. Utility Model Content

[0004] The purpose of this utility model is to provide a flat constant force spring support bracket, which has the advantage of facilitating internal adjustment and correction of the spring support bracket.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flat constant force spring support, characterized in that: it includes a support shell, the support shell has a cavity, one end of the support shell has an opening, the other end of the support shell has a locking block, an adjusting assembly is movably connected inside the support shell, the adjusting assembly includes an adjusting plate slidably connected to the cavity, a limiting plate movably connected to the inside of the cavity, and a telescopic spring disposed between the adjusting plate and the limiting plate, a pipe connection seat is fixed on the side of the adjusting plate away from the limiting plate, and the adjusting plate is close to... A limiting screw is fixed to one side of the limiting plate. Both the limiting plate and the locking block are provided with adjustment holes for the limiting screw to pass through. The end of the limiting screw extending out of the locking block is threadedly connected to a locking block. Multiple adjustment blocks can also be detachably connected between the locking block and the limiting plate. Guide sliders are provided on both sides of the adjustment blocks. The inner wall of the cavity is provided with a guide groove for the guide slider to slide. The guide groove is set along the length direction of the bracket sleeve. The inner wall of the cavity is also provided with a circumferential fixed groove communicating with the guide groove. The side wall of the circumferential fixed groove near the locking block is provided with a positioning groove.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: A flat constant force spring support, such as Figure 1 and Figure 2 As shown, it includes a bracket housing 1, a cavity 2 inside the bracket housing 1, an opening 3 at one end of the bracket housing 1, and a locking block 4 at the other end of the bracket housing 1.

[0019] An adjustment assembly is movably connected inside the bracket housing 1. The adjustment assembly includes an adjustment plate 5 that is slidably connected to the cavity 2, a limiting plate 6 that is movably connected to the inside of the cavity 2, and a telescopic spring 7 located between the adjustment plate 5 and the limiting plate 6. A pipe connection seat 8 is fixed on the side of the adjustment plate 5 away from the limiting plate 6. The pipe is fixed through the pipe connection seat 8. When the pipe oscillates and fluctuates, the telescopic spring 7 between the adjustment plate 5 and the limiting plate 6 is used to achieve buffer adjustment, so as to reduce the potential deformation of the equipment and pipe under conditions such as thermal displacement.

[0020] To facilitate the adjustment and control of the elastic buffering process between the adjusting plate 5 and the limiting plate 6, a limiting screw 9 is fixed on the side of the adjusting plate 5 near the limiting plate 6. Both the limiting plate 6 and the locking block 4 are provided with adjusting holes 10 for the limiting screw 9 to pass through. A protective ring block 22 (e.g., ...) is provided at the opening of the adjusting hole 10. Figure 3 As shown, the limiting screw 9 passes through the adjusting hole 10, and the protective ring block 22 can reduce the increase in hole diameter caused by repeated friction in the adjusting hole 10. A locking block 11 is threadedly connected to one end of the limiting screw 9 that extends out of the locking block 4. By tightening the locking block 11, the relative positional relationship between the adjusting plate 5 and the limiting plate 6 can be limited.

[0021] Due to aging after prolonged use and elastic deformation, especially in the internal telescopic spring 7, the overall elastic coefficient of the device needs to be corrected. Multiple adjusting blocks 12 can be detachably connected between the locking block 4 and the limiting plate 6. The combination of these adjusting blocks 12 allows for adjustment of the overall elastic coefficient of the device during daily use. Guide sliders 13 are provided on both sides of the adjusting blocks 12, and guide grooves 14 are provided on the inner wall of the cavity 2 for the guide sliders 13 to slide. A closing block 21 is provided at the end of the guide groove 14 near the opening 3. The adjusting block 12 is manually inserted from the end where the locking support block 4 is located according to actual needs. The guide groove 14 is set along the length direction of the bracket housing 1. After the adjusting block 12 is inserted along the guide groove 14, the inner wall of the cavity 2 is also provided with a circumferential fixed groove 15 that communicates with the guide groove 14. The side wall of the circumferential fixed groove 15 near the locking support block 4 is provided with a positioning groove 16. The installer can rotate the adjusting block 12 horizontally to make the guide slider 13 slide in the circumferential fixed groove 15 and fall into the positioning groove 16. Finally, under the elastic compression of the telescopic spring 7, the stable installation is achieved, thereby achieving the padding effect of the limiting piece 6, so as to meet the correction and strengthening of the elastic performance of the whole device under aging conditions.

[0022] To ensure the stability of the fit between multiple adjusting blocks 12 after insertion, an auxiliary groove 17 is provided on one side wall of the adjusting block 12, and an auxiliary insertion block 18 is provided on the other side. The insertion fit between the auxiliary insertion block 18 and the auxiliary groove 17 helps to improve the consistency of force feedback among the adjusting blocks 12. An anti-slip pad 19 is also provided on the side where the limiting plate 6 abuts against the adjusting block 12, which can reduce the relative slippage between the limiting plate 6 and the adjusting block 12. In order to improve the stability of the force on the adjusting plate 5, a guide ear block 20 is provided on the side wall of the adjusting plate 5 to cooperate with the guide groove 14. The cooperation between the guide ear block 20 and the guide groove 14 ensures the stability and reliability of the force on the pipe connection seat 8, and reduces the internal movement state deviation caused by uneven force.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
