Embodiment 1

[0022] Embodiments of the present invention provide a replaceable core pad sealing structure, such as Figure 1-2 As shown, it includes: a body 1, a core pad 2, a core shell 3 and a spring 4, the body 1 is provided with a lip 5, the core pad 2 is correspondingly arranged at the lip 5, and the core pad 2 is detachably arranged in the core shell 3 , the spring 4 is sleeved on the core shell, and the core shell 3 is pressed by the spring 4 to make the core pad 2 press the corresponding lip 5 to achieve sealing.

[0023] Wherein, the body 1 is also provided with a first sealing ring 18 and a second sealing ring 19 , and the sealing performance of the body 1 is increased by the arrangement of the first sealing ring 18 and the second sealing ring 19 .

[0024] Wherein, the core pad 2 and the core shell 3 are cooperatively arranged, so as to improve the fixing effect of the core pad 2 . By wrapping the spring 4 on the core shell 3, the core pad 2 is pressed against the lip 5 of the ...

Embodiment 2

[0027] In this embodiment, as Figure 1-2 As shown, the core shell 3 includes a first core shell 6 and a second core shell 7 formed by extending from the first core shell 6 toward the body 1. The second core shell 7 is recessed inward to form a mounting groove 8, and the core pads 2 are matched to each other. In the installation groove 8 , the spring 4 is sleeved on the first core shell 6 . The installation grooves 8 are arranged to facilitate the installation of the core pad 2, so that the fixing effect of the core pad 2 is good. The spring 4 is sleeved on the first core shell 6, and the core shell 3 can be pressed toward the body 1 by the pressure of the spring 4, so that the core shell 3 can press the lip 5 of the body 1 to achieve sealing , the sealing effect is better.

[0028] In this embodiment, as Figure 1-2 As shown, a through slot 9 is also provided in the first core shell 6 . The through groove 9 can be used for better cooperation between the contact surfaces o...

Embodiment 3

[0032] On the basis of the second embodiment, in this embodiment, as Figure 1-2 As shown, the core pad 2 includes a first core pad 11 and a second core pad 12 formed by extending from the first core pad 11 toward the body 1 . The second core pad 12 is snapped into the installation slot 8 . By arranging the first core pad 11 in the installation slot 8, the second core pad 12 is clamped at the position of the installation slot 8 close to the body 1, so that the second core pad 12 and the installation slot 8 are clamped and fixed. It is convenient to replace the core pad 2 in the installation groove 8 .

[0033] In this embodiment, as Figure 1-2 As shown, the installation groove 8 includes a first installation groove 13 and a second installation groove 14 . The first core pad 11 is fitted in the first installation groove 13 , and the second core pad 12 is fitted in the second installation groove 14 . By cooperating and installing the first core pad 11 and the second core pad ...

Abstract

The invention is suitable for the technical field of core pad sealing, and provides a replaceable core pad sealing structure which comprises a body, a core pad, a core shell and a spring, the body is provided with a lip, the core pad is correspondingly arranged at the lip, the core pad is detachably arranged in the core shell, the spring is arranged on the core shell in a sleeving mode, and the core pad is detachably arranged in the core shell. The core shell is compressed by the spring, so that the core pad is compressed corresponding to the lip to realize sealing; the core pad is correspondingly arranged at the lip of the body, the core pad is detachably arranged in the core shell, the core shell is sleeved with the spring, and the core shell is tightly pressed through the spring so that the core pad can be tightly pressed corresponding to the lip to achieve sealing. In this way, elastic sealing of the lip of the body can be improved, the core pad and the core shell are convenient to assemble, and replacement is convenient when abrasion is treated. According to the embodiment of the invention, the whole assembly is convenient, the sealing effect is good, the replacement is convenient, and the product reliability is ensured.

Description

technical field [0001] The invention belongs to the technical field of core pad sealing, and in particular relates to a replaceable core pad sealing structure. Background technique [0002] Sealing plug assemblies are used to seal mechanical workpieces to improve product quality. The traditional sealing plug assembly process is to process the machined parts into a single product, and the mold is individually encapsulated at the seal. However, this process takes a lot of time, and if the finished components are scratched during use, The wear and the indentation are too large, so that the normal sealing cannot be performed, and the whole components need to be replaced, which is costly. SUMMARY OF THE INVENTION [0003] The embodiments of the present invention provide a replaceable core pad sealing structure, which aims to solve the above problems of troublesome overall assembly, inconvenient replacement and poor sealing performance. [0004] The embodiment of the present i...
