As a preferable scheme, the inner side wall of the connecting sleeve is provided with a pipe connecting groove and a wedge-shaped groove, and the wedge-shaped groove is positioned at the outer side of the pipe connecting groove.
Preferably, the surface of the clamping piece is provided with a wedge-shaped insert block, and the wedge-shaped insert block is matched with the wedge-shaped groove.
As an optimal scheme, the surface of the connecting sleeve member is fixedly connected with a rubber pad.
The utility model has the technical effects and advantages that:
1. when activity external member threaded connection is on the connection external member, the rubber pad is located between activity external member and the connection external member, the rubber pad texture is soft, coefficient of friction is big, can increase frictional force, ensure the compactness of being connected between activity external member and the connection external member, tubular product one end inserts and connects the piping groove, with takeover groove butt, drive the fastener through rotating activity external member and remove for wedge on the fastener inserts to the wedge inslot, the fastener forms the extrusion to the tubular product outer wall promptly, thereby accomplish the fixed connection of tubular product, tubular product connection easy operation is convenient, and connecting efficiency is high, convenient to use.

FIG. 1 is a schematic diagram of the overall structure of the present utility model.
Fig. 2 is a schematic plan view of the present utility model.
FIG. 3 is a schematic plan view of the pipe connection of the present utility model to a connection kit.
In the figure: 1. a connection kit; 101. a liquid passing cavity; 102. an external thread; 103. a pipe receiving groove; 104. wedge-shaped grooves; 2. a movable sleeve; 201. an internal thread; 3. a clamping piece; 301. wedge-shaped inserts; 4. and a rubber pad.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides a structure of a polyethylene pipe connecting sleeve 1 as shown in figures 1-3, which comprises the connecting sleeve 1, a movable sleeve 2 and a clamping piece 3, wherein a liquid through cavity 101 is formed in the connecting sleeve 1, the clamping piece 3 is placed in the movable sleeve 2, an external thread 102 is formed on the outer surface of the connecting sleeve 1, an internal thread 201 is formed on the inner side wall of the movable sleeve 2, and the connecting sleeve 1 and the movable sleeve 2 are connected through the external thread 102 and the internal thread 201.
In this embodiment, the inner side wall of the connection sleeve 1 is provided with a pipe receiving groove 103 and a wedge groove 104, the wedge groove 104 is located at the outer side of the pipe receiving groove 103, the surface of the clamping piece 3 is provided with a wedge-shaped insert 301, and the wedge-shaped insert 301 is engaged with the wedge groove 104; the pipe connecting groove 103 is inserted into one end of the pipe, the pipe connecting groove 103 is abutted against the pipe connecting groove 103, the clamping piece 3 is driven to move by rotating the movable sleeve piece 2, the wedge-shaped block on the clamping piece 3 is inserted into the wedge-shaped groove 104, namely, the clamping piece 3 extrudes the outer wall of the pipe, the fixed connection of the pipe is completed, the pipe connection operation is simple and convenient, and the connection efficiency is high, so that the pipe connecting device is convenient to use.
