[0020] The technical solution of the utility model is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0021] Embodiment 1:

[0022] The internal corrugated PP tube core provided in the present application comprises a tube core body 1; corrugated strips 3 are installed at equal intervals in the inner cavity of the tube core body 1, and a connecting mechanism 5 is fixedly installed at one end of the tube core body 1;

[0023] The connecting mechanism 5 includes a mounting seat 501, a spring 502, a fixing shell 503, a mounting cavity 504 and a fixing ball 505. The mounting seat 501 is fixedly mounted on one end of the tube core body 1. The spring 502 is mounted on the outer side of the mounting seat 501. The fixing shell 503 is slidably mounted on the outer side of the spring 502. The mounting cavities 504 are evenly spaced on the inner side of the mounting seat 501. The fixing balls 505 are mounted inside the mounting cavities 504. A concave cavity 401 is formed on the surface of the connecting seat 4. The size of the concave cavity 401 matches the size of the fixing ball 505.

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when a person installs two groups of tube core bodies 1, the connecting seat 4 in one group of tube core bodies 1 is matched with the mounting seat 501 at one end of the other group of tube core bodies 1, and then the person pulls the fixing shell 503 outward to deform the spring 502 inside the fixing shell 503, and the fixing ball 505 inside the mounting seat 501 is squeezed. When the fixing ball 505 corresponds to the concave cavity 401, the fixing ball 505 will bounce into the concave cavity 401 under its own elastic force, and then the person loosens the fixing shell 503, and the fixing shell 503 will be in its The internal spring 502 pops outward under the elastic force, so that the fixing ball 505 can be fixed inside the concave cavity 401, so that the two groups of tube core bodies 1 can be quickly connected into a whole for use, and the sealing between the tube core bodies 1 can be further ensured. Through the setting of the connecting mechanism 5, not only can the two groups of tube core bodies 1 be quickly spliced ​​and installed, but also in the process of splicing and installing the tube core bodies 1, there is no need to use external tools for installation, which can further improve the work efficiency and convenience of splicing and installing the two groups of tube core bodies 1.

[0025] Further, a buffer mechanism 2 is provided in the inner wall of the tube core body 1, a connecting seat 4 is fixedly installed at the other end of the tube core body 1, the buffer mechanism 2 includes a buffer cavity 201 and a buffer rod 202, the buffer cavity 201 is opened in the wall cavity of the tube core body 1, and the buffer rods 202 are evenly spaced inside the buffer cavity 201;

[0026] Specifically, Figure 1 , Figure 2 As shown, when the tube core body 1 is used for a long time, the buffer rod 202 inside the buffer cavity 201 can buffer the external force, thereby preventing the external force from directly acting on the surface of the tube core body 1, and further protecting the tube core body 1, which can further increase the service life of the tube core body 1.

[0027] Working principle: When personnel install two groups of tube core bodies 1, the connecting seat 4 in one group of tube core bodies 1 is matched with the mounting seat 501 at one end of the other group of tube core bodies 1, and then the personnel pulls the fixed shell 503 outward to deform the spring 502 inside the fixed shell 503, and the fixed ball 505 inside the mounting seat 501 is squeezed. When the fixed ball 505 corresponds to the concave cavity 401, the fixed ball 505 will bounce into the inside of the concave cavity 401 under its own elastic force, and then the personnel releases the fixed shell 503, and the fixed shell 503 will pop outward under the elastic force of the spring 502 inside it, so that the fixed ball 505 can be fixed inside the concave cavity 401, so that the two groups of tube core bodies 1 can be quickly connected into a whole for use, and the sealing between the tube core bodies 1 can be further ensured.

[0028] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
