Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to an adjustable spring component. Background Art

[0002] At present, springs are a kind of mechanical parts that use elasticity to work. They are generally made of spring steel. They are used to control the movement of mechanical parts, alleviate impact or vibration, store energy, measure the size of force, etc. They are widely used in machines and instruments. Due to the wide range of uses of springs, it is necessary to optimize the use of springs.

[0003] For example, a spring assembly is disclosed in the Chinese utility model patent with announcement number CN204985454U. Although the above-mentioned prior art solves the problem that the existing spring assembly is inconvenient to rotate and takes up space during installation, the single length of the spring is basically made according to the model, and the length of each model is fixed. When the required spring length is not met by the general model, it is necessary to purchase or customize a new one. If the incompatible spring is forcibly stretched or compressed, it will only cause the spring to deform and be damaged. Therefore, customization or procurement is also possible when there is no hurry to use it. However, when the spring is in a hurry to use it, customization or procurement will waste a lot of time and affect the work progress. Therefore, it is necessary to design a spring assembly that can adjust the length of the spring when needed. Utility Model Content

[0004] In order to solve the technical problem that the length of the spring cannot meet the current use requirements, the utility model provides an adjustable spring assembly.

[0005] The utility model is implemented by the following technical scheme: an adjustable spring assembly, comprising two springs, a limit assembly for limiting the two springs is provided between the two springs, fixing assemblies for fixing adjacent springs to the limit assembly are provided on both sides of the limit assembly, two locking assemblies for locking the fixing assembly to prevent it from moving are sleeved on the limit assembly, and the limit assembly comprises a limit ring arranged between the two springs and a limit plate fixedly installed inside the limit ring.

[0006] Through the above technical solution, when the spring needs to be lengthened, a limit assembly is placed between the two spring sections, the two springs are fixed on the limit assembly using a fixing assembly, and finally the fixing assembly is locked with a locking assembly, so that the two spring sections can be used as one.

[0007] As a further improvement of the above solution, one end of the two springs extends to the inside of the limiting ring and fits with one side of the limiting plate.

[0008] Through the above technical solution, the limit plate can prevent the two spring sections from being misplaced during use.

[0009] As a further improvement of the above solution, the fixing assembly includes a fixing block arranged inside the limiting ring and sleeved on the adjacent springs, and a clamping column fixedly installed on both sides of the fixing block.

[0010] Through the above technical solution, the opening of the fixing block is sleeved on the spring, so when the fixing block is pressed, the part of the bottom of the spring extending out of the fixing block will also be pressed by the fixing block.

[0011] As a further improvement of the above solution, a plurality of sliding grooves are provided on the outer surface of the limiting ring, and one end of each of the clamping columns passes through an adjacent sliding groove.

[0012] Through the above technical solution, a sliding compression column outside the limiting ring can move the fixing block downward to compress the excess part of the spring.

[0013] As a further improvement of the above scheme, the locking assembly includes a threaded ring fixedly mounted on the limiting ring and having an external thread, a fixing ring threadedly mounted on the threaded ring, and an extrusion sleeve fixedly installed on one side of the fixing ring and mounted on the limiting ring.

[0014] Through the above technical solution, after the fixing ring is screwed onto the threaded ring, the extrusion sleeve will squeeze the clamping column, so that the fixing block will also squeeze and lock the spring.

[0015] As a further improvement of the above solution, a clamping groove matching the clamping column is provided on the inner ring surface of the extrusion sleeve.

[0016] Through the above technical solution, when the extrusion sleeve moves, the clamping groove will push the clamping column.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a limit assembly, a fixing assembly and a locking assembly. When the spring needs to be extended, the spring is rotated and inserted into the fixing block of the fixing assembly, so that the spring will enter the interior of the limit assembly. After multiple springs are operated in this way, the multiple springs will be connected together into a whole through the limit assembly and the fixing assembly, and then the locking assembly will be used to lock the fixing assembly to prevent the fixing assembly from moving. In this way, the part of one end of each spring that extends out of the fixing block will be pressed and locked by the fixing block. In this way, it is possible to avoid separating the multiple springs when in use. In this way, multiple springs can be combined together and used as one spring, and a long spring composed of multiple springs can be disassembled and used as a short spring, which makes the use of the spring more convenient.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 , an adjustable spring assembly of the present embodiment includes two springs 1, a limit assembly for limiting the two springs 1 is provided between the two springs 1, fixing assemblies for fixing adjacent springs 1 to the limit assemblies are provided on both sides of the limit assembly, and two locking assemblies for locking the fixing assembly to prevent it from moving are sleeved on the limit assembly, the limit assembly includes a limit ring 201 arranged between the two springs 1 and a limit plate 202 fixedly installed inside the limit ring 201, one end of the two springs 1 extends to the inside of the limit ring 201 and fits on one side of the limit plate 202, when the spring 1 needs to be lengthened, the limit assembly is placed between the two sections of the spring 1, the fixing assembly is used to fix the two springs 1 on the limit assembly, and finally the fixing assembly is locked with the locking assembly, so that the two sections of the spring 1 can be used as one section.

[0027] Combination Figure 2-Figure 4 The fixing assembly includes a fixing block 301 arranged inside the limiting ring 201 and sleeved on the adjacent spring 1, and a clamping column 302 fixedly installed on both sides of the fixing block 301. The outer surface of the limiting ring 201 is provided with a plurality of sliding grooves 5, and one end of each clamping column 302 passes through the adjacent sliding groove 5. The fixing block 301 opening is sleeved on the spring 1. In this way, when the fixing block 301 is compressed, the part of the bottom of the spring 1 extending out of the fixing block 301 will also be compressed by the fixing block 301.

[0028] Combination Figure 1 , Figure 2 and Figure 4The locking assembly includes a threaded ring 401 fixedly sleeved on the limiting ring 201 and provided with an external thread, a fixing ring 402 threadedly sleeved on the threaded ring 401, and an extrusion sleeve 403 fixedly installed on one side of the fixing ring 402 and sleeved on the limiting ring 201. The inner ring surface of the extrusion sleeve 403 is provided with a compression groove matched with the compression column 302. After the fixing ring 402 is screwed on the threaded ring 401, the extrusion sleeve 403 will squeeze the compression column 302, so that the fixing block 301 will also squeeze and lock the spring 1.

[0029] The implementation principle of an adjustable spring assembly in the embodiment of the present application is as follows: when a long spring 1 is needed, one end of the two springs 1 is inserted into the two fixing blocks 301 inside the limiting ring 201, and then the two springs 1 are rotated, and one end of the spring 1 extends out of the adjacent fixing blocks 301 and fits against one side of the limiting plate 202. After the two springs 1 are installed in this way, a fixing ring 402 is put on the limiting ring 201, and the fixing ring 402 is tightened on the threaded ring 401. During the tightening process, the clamping groove of the extrusion sleeve 403 will contact the clamping column 302, thereby moving the clamping column 302, and finally squeezing the clamping column 302 to Within a range, the pushed clamping column 302 will drive the fixing block 301 to move, and finally the moving fixing block 301 will press the extended spring 1 onto the limiting plate 202, so that the spring 1 can be fixed inside the limiting ring 201 through the sleeve and compression of the fixing block 301, so that a few additional springs 1 can be connected according to the required length. When a shorter spring 1 is needed, the several connected springs 1 can be disassembled to obtain the required length. This arrangement can not only combine or disassemble multiple springs 1 according to the required length, but also avoid the need for additional purchase or customization when the spring 1 used is not suitable.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
