Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

The specific embodiments are shown in fig. 1, 2, 3 and 5, a protective sleeve with a buffering effect, comprising a body 1 sleeved outside a corrugated pipe, and the key is that: the body 1 is from outside to inside including inoxidizing coating 2, buffer layer 3 and inlayer 4, inlayer 4 internal surface is smooth, and inoxidizing coating 2 bottom outside equipartition has articulated support 5, and articulated support 5 is provided with 4-8, articulates on the articulated support 5 has connecting plate 6, selects the length of connecting plate 6 according to actual demand, has offered threaded hole 601 on the connecting plate 6. In actual use, the corrugated pipe sometimes needs to pass through the wall body of some buildings, and the angle of the connecting plate 6 can be changed, so that the corrugated pipe can be fixed on the wall body through the threaded hole 601, and can be horizontally inserted into the hole of the wall body with the body 1, thereby protecting the corrugated pipe passing through the wall body.

As shown in fig. 3, the cushion layer 3 is an elastic bead or an elastic rubber layer. The elastic small ball or the elastic rubber layer can play a role in elastic shock absorption and buffering, and the corrugated pipe inside is protected.

As shown in fig. 3 and 4, the protection layer 2 includes a cylindrical shell 201, a blocking portion 202 and a boss 203, the blocking portion 202 is disposed in a ring shape extending inward at two ends of the cylindrical shell 201, the boss 203 is disposed on the blocking portion 202, grooves 401 matched with the boss 203 are formed at two ends of the inner layer 4, the protection layer 2 is made of metal, a filling opening 204 is formed on the blocking portion 202, elastic pellets are filled through the filling opening 204 after the inner layer 4 and the protection layer 2 are mounted, and an elastic rubber layer can be placed on an inner wall of the protection layer 2 and then is mounted and connected with the protection layer 2 and the inner layer 4.

The top end of the protective layer 2 is provided with a connecting block 7 corresponding to the hinged support 5, and the connecting block 7 is provided with a plug interface 701 matched with the connecting plate 6. The socket 701 and the connecting plate 6 cooperate with two protective sleeves having a buffer effect, that is to say, the number of the protective sleeves can be set according to the length of the actual requirement. The inner layer 4 is made of hard rubber or polytetrafluoroethylene. The hard rubber is internally smooth, and polytetrafluoroethylene is a smooth material, so that friction between the hard rubber and the corrugated pipe can be reduced.
