[0003] A search revealed patent document CN205350562U, which discloses a pipe connector. The first connecting end of the pipe connector features a rotating shaft, around which a connecting bolt rotates and engages a notch in the second connecting end. Simply tightening the connecting bolt secures the two clamps, making operation easy. A latch on the second connecting end prevents the connecting bolt from slipping out of the notch. The rubber connecting band features a triangular design with protruding and concave ends, ensuring a tight connection and preventing leakage.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The embodiment of the utility model discloses a pipe connector used for plastic pipes.

[0028] The utility model provides Figure 1-5 The pipe connector shown is for use with plastic pipes and includes a housing 1. The housing 1 is open and has connecting plates 2 fixedly provided at both ends of the opening. The connecting plates 2 are welded to the housing 1. The two connecting plates 2 are bent and have connecting cavities inside. A sealing ring 3 is provided through the inner wall of the housing 1. Steel tooth rings 4 are provided on both sides of the sealing ring 3. The steel tooth rings 4 are in contact with the inner wall of the housing 1. The two steel tooth rings 4 are arranged in multiple layers on both sides.

[0029] The lower ends of the two connecting plates 2 are in contact with each other and a bridge plate 5 is provided. A plurality of strip holes 11 are provided inside the bridge plate 5 and the bridge plate 5 covers the outer side of the sealing ring 3.

[0030] A threaded locking shaft 6 and a through-hole locking shaft 7 are respectively inserted into the interior of the two connecting plates 2. Two symmetrically arranged bolts 8 are passed through the shaft walls of the threaded locking shaft 6 and the through-hole locking shaft 7. A plurality of spaced-apart through-holes 12 are opened inside the connecting plate 2 to cooperate with the bolts 8.

[0031] When connecting the plastic pipe, the end of the plastic pipe is inserted into the outer shell 1 and contacts the inner wall of the sealing ring 3 and the steel tooth ring 4. Then the bridge plate 5 is placed inside the outer shell 1. Then the threaded locking shaft 6 and the through-hole locking shaft 7 are inserted into the two connecting plates 2, and the bolt 8 is inserted into the threaded locking shaft 6 and the through-hole locking shaft 7. The outer shell 1 is clamped by tightening the bolt 8. Since the steel tooth ring 4 is a multi-layer structure, it can be in close contact with the outer wall of the plastic pipe, thereby improving the bite force on the plastic pipe and increasing the stability of the connection.

[0032] In order to ensure that the bolt 8 can be stably inserted into the connecting plate 2 to complete the locking of the housing 1 and the pipe, Figure 1 and Figure 4 As shown, the shaft walls of the threaded locking shaft 6 and the through-hole locking shaft 7 are both provided with connecting holes 9 for the matching bolts 8 to pass through, and the shaft walls of the threaded locking shaft 6 and the through-hole locking shaft 7 are both provided with countersunk grooves 10, which are connected to the connecting holes 9.

[0033] Before tightening the bolt 8, the threaded locking shaft 6 and the through-hole locking shaft 7 can be inserted into the internal connecting cavity of the connecting plate 2, and the connecting hole 9 and the through-hole are at the same horizontal line. At this time, the end of the bolt 8 can be inserted into the inside of the connecting plate 2 and inserted into the connecting hole 9, thereby completing the locking setting of the bolt 8. The position of the screw head of the bolt 8 can be effectively placed through the setting of the countersunk groove 10 to ensure the stability of the setting of the bolt 8.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
