[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] As attached Figure 1-6 A nitrogen spring cloth dust cover shown in the figure comprises a nitrogen spring 1, a first limiting boss 2 is provided on the outer surface of the output end of the nitrogen spring 1, a fixing hole 3 is provided in the middle of the output end of the nitrogen spring 1, a support ring 6 is installed on the output end of the nitrogen spring 1, a second limiting boss 7 is provided on the upper surface of the support ring 6, a screw countersunk hole 8 is provided in the middle of the upper surface of the support ring 6, a cloth sleeve 4 is sleeved and installed on the outer surface of the support ring 6, the middle part of the outer surface of the cloth sleeve 4 is arranged in a sandwich shape, a spring limiting hoop 5 is installed on the inner surface of the sandwich-shaped part of the cloth sleeve 4, the other end of the cloth sleeve 4 is sleeved and installed in the middle of the outer surface of the output end of the nitrogen spring 1, and the outer surface of the sleeve connection between the cloth sleeve 4 and the support ring 6 and the outer surface of the sleeve connection between the cloth sleeve 4 and the nitrogen spring 1 are sleeved and installed with a clamp 9, which is respectively installed on the lower surfaces of the first limiting boss 2 and the second limiting boss 7.

[0021] During operation, first, one end of the cloth sleeve 4 can be sleeved on the outer surface of the support ring 6, and the clamp 9 can be sleeved on the lower surface of the second limiting boss 7 to lock and fix the support ring 6 and the cloth sleeve 4. At this time, when the second limiting boss 7 limits the locking position of the clamp 9, the loosening phenomenon of the clamp 9 during the locking process can be avoided. At this time, the support ring 6 can be covered to the output end of the nitrogen spring 1, and the screw countersunk hole 8 opened in the middle of the upper surface of the support ring 6 is aligned with the fixing hole 3 opened at the output end of the nitrogen spring 1. At this time, the screw can be inserted through the screw countersunk hole 8 and inserted into the fixing hole 3 to complete the fixed connection between the support ring 6 and the nitrogen spring 1.

[0022] When one end of the cloth sleeve 4 is connected to the nitrogen spring 1, the other end of the cloth sleeve 4 can be sleeved on the first limiting boss 2 set on the outer surface of the nitrogen spring 1, and the clamp 9 is sleeved on the lower surface of the first limiting boss 2 to lock and fix the cloth sleeve 4 and the nitrogen spring 1. At this time, when the first limiting boss 7 limits the locking position of the clamp 9, the loosening phenomenon that the clamp 9 is easy to occur during the locking process can be avoided, thereby ensuring the stability of the installation between the cloth sleeve 4 and the nitrogen spring 1. At this time, the cloth sleeve 4 can protect the exposed state of the output end of the nitrogen spring 1 during operation, thereby avoiding the problem that the output end of the nitrogen spring 1 is easily contaminated with impurities during operation. At the same time, the cloth sleeve 4 is made of high-temperature resistant cloth material (such as silicone cloth), which has good air permeability and heat dissipation, and can ensure the normal heat dissipation effect of the nitrogen spring 1 while protecting it. It is soft in texture and not easy to break when folded. It can be correspondingly contracted and expanded with the telescopic operation of the output end of the nitrogen spring 1, thereby ensuring the comprehensiveness of protection.

[0023] When the cloth cover 4 contracts and expands accordingly with the telescopic operation of the output end of the nitrogen spring 1 to provide comprehensive protection, the spring limiting hoop 5 arranged inside it can contract and expand accordingly. At this time, the spring limiting hoop 5 can be used to support the cloth cover 4, which is conducive to avoiding the collapse problem of the cloth cover 4 that is easy to occur during the contraction and expansion process, thereby avoiding the problem that the cloth cover 4 collapses and contacts with the output end of the nitrogen spring 1 to affect its normal operation. The spring limiting hoop 5 has a spring-shaped spiral structure, which is conducive to providing a more comprehensive support effect for the cloth cover 4 without affecting the normal use of the cloth cover 4.

[0024] In summary: the fabric dust cover has a simple structure and lower use cost. It is also easier to install during use and is not easy to deform or collapse during use. It is conducive to providing a more comprehensive protection effect and will not affect the normal use of the nitrogen spring.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
