Description

Sealed drag chain Technical Field The utility model relates to the technical field of drag chains, in particular to a sealed drag chain. Background In the field of modern industry, drag chains are widely used as a key component in machine tools, machines and various types of automation equipment. The prior art of drag chains is mature, the drag chain products on the market are various in variety and different in design concept, and the purpose of the drag chain is to meet the diversified use requirements of different machines. However, through intensive research and feedback of practical application, the problem of insufficient tightness of the current drag chain is found. Gaps exist between the joints of the upper shells and the lower shells of a plurality of drag chains, and impurities such as dust, fragments, liquid and the like can easily enter the drag chains, so that the damage to protected objects such as cables and pipelines in the drag chains is caused, the normal operation of equipment is affected, and the service life and the stability of the equipment are reduced. For example, in some processing environments with more dust, the dust can enter the drag chain through the gaps and then adhere to the surface of the cable, and faults such as short circuit and the like can be caused after the dust is accumulated for a long time, so that maintenance cost and equipment shutdown risk are increased. Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present utility model. Disclosure of utility model The utility model aims to provide a sealed drag chain. In order to achieve the above purpose, the utility model adopts the following technical scheme: A sealed drag chain comprising: The first enclosing piece and the second enclosing piece enclose to form a protection space; the first locking assembly part and the second locking assembly part which are correspondingly locked and assembled are arranged on the first enclosing part and the second enclosing part in a one-to-one correspondence manner and are used for locking the enclosing states of the first enclosing part and the second enclosing part; and the first sealing assembly part and the second sealing assembly part which are correspondingly assembled in a sealing way are arranged on the first enclosing part and the second enclosing part in a one-to-one correspondence manner, and are used for sealing the part of the joint surface between the first enclosing part and the second enclosing part in the enclosing state. For the first locking assembly part and the second locking assembly part, the first locking assembly part and the second locking assembly part are arranged on the first enclosing part and the second enclosing part in a one-to-one correspondence mode, specifically, the first locking assembly part is connected with the first enclosing part, the second locking assembly part is connected with the second enclosing part, and the connection mode is not limited. The first enclosing piece encloses with the second and closes the piece and enclose and close formation protection space, and protection space is used for protecting inside article. The first locking assembly part and the second locking assembly part are correspondingly locked and assembled, so that stable fitting and assembling of the first enclosing part and the second enclosing part are realized, stability of a protection space is improved, and the task of preventing sundries from entering the protection space through a gap between the first enclosing part and the second enclosing part is also born. The protection space for preventing sundries from entering is to avoid as much as possible, and a very small amount of sundries can enter the protection space in the long-term use process of the sealed drag chain. By means of the cooperation of the first sealing assembly part and the second sealing assembly part, sundries are further prevented from entering the protection space through gaps between the first enclosing part and the second enclosing part, the sealing performance of the protection space is improved, the drag chain is particularly suitable for scenes with high requirements on sealing performance and protection capability, and the application range of the drag chain is enlarged. By way of example, the first seal assembly may be considered in some embodiments as part of the first enclosure and may not be considered as a separate structure. In summary, the first locking assembly part and the second locking assembly part realize locking of the first enclosing part and the second enclosing part, and can also be used for improving the tightness of the drag chain, and the first sealing assembly part and the second sealing assembly part are mainly used for improving the tightness of the drag chain, but can also be used for improving the assembly and combination stability of the first enclosing part and the second enclosing part.
