Problems solved by technology
[0004] The purpose of the present invention is to provide a copper tube that is easy to connect. By setting a connecting sleeve at the joint of the two copper tubes, the tightness between the copper tubes can be realized by squeezing the connecting sleeve and the spring force, and The connection of the copper tube is strengthened by the mutual clamping of the first hemispherical convex body on the pipe sleeve and the card slot on the chute, which solves the problem that the existing copper tube connection method is cumbersome, and the sealing performance is poor, which reduces people's work efficiency. question

The invention discloses a copper pipe convenient to connect, and relates to the technical field of copper pipes. The copper pipe convenient to connect comprises a copper pipe body. A pipe sleeve is fixedly connected with the peripheral side face of the end portion of one end of the copper pipe body, and a connecting sleeve is connected to the end portion of the other end of the copper pipe body inan inserting mode. A plurality of sliding grooves are evenly formed in the peripheral side face of the end portion, connected to the copper pipe body in an inserting mode, of the copper pipe body. Aplurality of sets of clamping grooves which are formed in a staggered mode communicate with the two sides of the sliding grooves. A plurality of first hemispheric convex bodies matched with the clamping grooves are evenly formed in the inner surface of the end portion of the pipe sleeve. The connecting sleeve is of a cylindrical structure with through holes. According to the copper pipe convenientto connect, the connecting sleeve is arranged at the connecting position of the two copper pipes, by extruding the connecting sleeve and the spring force, and the sealing between the copper pipes isachieved; and the first hemispheric convex bodies on the pipe sleeve are connected to the clamping grooves on the siding grooves in a clamping mode to strengthens the connection between the copper pipes, the connection mode is simple and convenient, and the work efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of copper tubes, in particular to a copper tube which is easy to connect. Background technique [0002] Because of its hard texture, non-corrosion resistance, high temperature resistance and high pressure resistance, copper pipes are widely used in tap water pipes, heating, and refrigeration pipes, and are the first choice for modern air conditioners and commercial housing installations. [0003] At present, when the copper tubes are used and connected to each other, connecting pieces are often added outside the copper tubes to connect the copper tubes. The connection method is cumbersome, and the sealing performance cannot be guaranteed, which directly reduces the workers' work work efficiency, and the working performance of the copper tube cannot be guaranteed, so a kind of copper tube that is convenient for people to connect during use and has good sealing performance needs to be studied.
