Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a round pipe connection kit. Background Art

[0002] A round tube refers to a pipe with openings at both ends and a hollow concentric circle cross-section. The common round tube connectors on the market usually directly insert two round tubes at both ends of the connector, and the round tubes inserted at both ends of the connector are easily misaligned. In addition, the existing round tube connectors are usually flush with the end faces of the round tubes, and gaps are easily generated during the actual installation process, resulting in poor sealing of the connection between the connector and the round tube.

[0003] After searching, the Chinese patent application number CN202222317684.0 discloses a glass fiber reinforced plastic round tube butt connector, including two round tube bodies, and flanges are fixedly arranged on the outer walls of the opposite sides of the two round tube bodies. However, since the above technical solution also needs to contact the flanges arranged on the outside of the round tubes in order to connect and fix the two round tubes, there is still a need to fix the flanges on the connecting ends of the round tubes before the two round tubes can be fixedly connected through the connector, and the two round tubes cannot be directly sealed and butted, resulting in a low efficiency of the round tube butt installation. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a round pipe connection kit.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A round tube connection kit comprises a tube sleeve, a connection block is fixed on the inner wall of the tube sleeve, an outer wall of one side of the connection block is provided with an installation groove, a fixing slider is slidably connected to the inner wall of the installation groove, a limiting groove is provided on the outer wall of one side of the fixing slider, a spring is inserted into the inner wall of the limiting groove, a fixing hole is provided on the outer wall of the tube sleeve, the spring is inserted into the inner wall of the fixing hole, and a fixing screw is threadedly connected to the inner wall of the fixing hole.

[0007] As a further solution of the utility model: a round tube body is inserted into the outer wall of the connecting block and the fixing sliding block.

[0008] As a further solution of the utility model: a clamping groove is formed on the outer wall of one side of the fixing sliding block, a clamping block is fixed on the inner wall of one side of the pipe sleeve, and the clamping block is inserted into the inner wall of the clamping groove.

[0009] As a further solution of the utility model: arc-shaped cavities are respectively formed on the outer walls of both sides of the fixing slider.

[0012] The beneficial effects of the utility model are:

[0013] 1. The fixing slider is slidably connected to the inner wall of the installation groove, the spring is fixed in the fixing hole at one end of the pipe sleeve by the fixing screw, and the other end of the spring is inserted into the limiting groove on one side of the fixing slider. After the round tube body is inserted into one end of the pipe sleeve, the fixing slider can be pressed against the inner wall of the round tube body by the elastic force of the spring, and cooperate with the connecting block to support and fix the round tube body inserted on one side of the pipe sleeve. At the same time, the pipe sleeve can block and seal one end of the round tube body, and while supporting and fixing the round tube body inserted on one side, improve the sealing performance of the connection part between the pipe sleeve and the round tube body, so as to facilitate the sealing connection of the two round tubes and improve the round tube connection and installation efficiency.

[0014] 2. After the locking slider is pressed against the inner wall of the pipe sleeve by the elastic force of the spring, the groove on one side of the locking slider will be stuck on the block on the inner wall of the pipe sleeve, thereby limiting the locking slider slidably connected to the inner wall of the installation groove, improving the supporting and fixing effect of the locking slider and the connecting block on the inner wall of the round tube body, and at the same time, the lines inside the round tube body can pass through the installation groove and the connecting kit.

[0015] 3. The support bar can support the inner wall of the circular tube body sleeved on the outer wall of the tightening slider and the connecting block, thereby improving the supporting and limiting effect of the connecting block and the tightening slider on the circular tube body plugged into the outer wall; the arc-shaped cavity can improve the stability of the overall structure of the tightening slider, while reducing the overall weight of the connecting kit and improving the structural strength of the overall structure of the connecting kit.
