Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a pipe joint. Background Art

[0002] When installing pipelines, pipe joints are needed to connect adjacent pipes. However, existing pipe joints have the following problems: (1) Some pipe joints connect two pipes only through threads. If the threads become loose, the pipe joints will be separated from each other, affecting the connection effect and sealing performance; (2) Some pipe joints connect two pipes by hot melting, which is inconvenient to install and cannot be replaced if damaged. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a pipe joint to solve the problems mentioned in the above background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A pipe joint comprises a hollow pipe body and two positioning sleeves for accommodating the ends of the pipe body to be inserted. The middle part of the pipe body is rotatably connected to a turntable via a rotating bearing. Two clamping columns are respectively fixed on both sides of the turntable, and the two clamping columns on the same side are symmetrically arranged with respect to the pipe body. The positioning sleeve comprises a collar and a clamp fixed to one side of the collar. Two symmetrical arc grooves are arranged on the side of the collar away from the clamp. The two clamping columns on the same side of the turntable can be inserted into the two arc grooves. Rotating the turntable can make the clamping columns rotate in the arc grooves. A clamping mechanism for fixing the clamping columns is arranged in the arc grooves.

[0006] Preferably, the clamping mechanism includes a groove opened on the ring and connected to one side of the arc groove, a clamping block slidably connected to the groove, and a spring connected to the groove, one end of the spring is connected to the bottom of the clamping block, and the top of the clamping block is an inclined surface. The clamping column squeezes the inclined surface of the clamping block to make it completely hidden in the groove, and after the clamping column completely passes through the clamping block, the clamping block can press the clamping column tightly in the arc groove.

[0007] The above technical solution fixes the positioning sleeve at the end of the pipe, then inserts the pipe body into the two pipes, inserts the clamping column into the corresponding arc groove, and then rotates the turntable to rotate the clamping column in the arc groove. During the rotation of the clamping column, the inclined surface of the clamping block is squeezed so that the clamping block is completely hidden in the groove. When the clamping column completely passes through the clamping block, the clamping block pops outward under the action of the spring and presses the clamping column tightly against the end wall of the arc groove, thereby completing the fixation of the turntable and the positioning sleeve.

[0008] Preferably, the inner wall of the collar is provided with an internal thread.

[0009] The above technical solution can threadably connect the collar to the port of the pipe through the internal thread, and is suitable for connecting pipes with external threads.

[0010] Preferably, both ends of the tube are tapered.

[0011] In the above technical solution, the end of the pipe body is tapered to facilitate its insertion into the pipe to be connected.

[0012] Preferably, the outer wall of the tube body is provided with a plurality of annular grooves, and sealing gaskets are embedded in the annular grooves.

[0013] The above technical solution can improve the sealing performance of the pipeline connection by arranging a sealing gasket.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] Connect the positioning sleeve to the ends of the two pipes, fix the positioning sleeve on the pipes through the clamp, then insert the two ends of the pipe body into the two pipes respectively, and insert the clamping columns on both sides of the turntable into the corresponding arc grooves, then rotate the turntable to make the clamping columns rotate in the arc grooves, and clamp the clamping columns through the clamping mechanism to complete the docking of the pipes. It is not only convenient to install and disassemble, but also has a stable connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1 , Figure 2 and Figure 3 A pipe joint includes a hollow pipe body 1 and two positioning sleeves 2 for accommodating the insertion of the pipe body. The two ends of the pipe body 1 are tapered to facilitate the insertion of the pipe body 1 into two pipes. The middle part of the pipe body 1 is rotatably connected to a turntable 4 through a rotating bearing 3. Two clamping columns 5 are respectively fixed on both sides of the turntable 4. The two clamping columns 5 on the same side are symmetrically arranged with the pipe body 1. The positioning sleeve 2 includes a collar 201 and a clamp 202 fixed to one side of the collar. The side of the collar 201 away from the clamp is provided with two symmetrical arc grooves 203, and the inner wall of the collar 201 is provided with an internal thread 204. The collar 201 is sleeved on the end of the pipe. If the outer wall of the pipe does not have an external thread, the collar 201 can be fixed on the pipe through the clamp. If the outer wall of the pipe is provided with an external thread, the collar 201 can also be connected to the pipe thread through the internal thread to improve the connection strength between the positioning sleeve 2 and the pipe.

[0024] The two clamping columns 5 on the same side of the rotating disk 4 can be inserted into the two arc-shaped grooves 203, and the rotating disk 4 can rotate the clamping column 5 in the arc-shaped groove 203. A clamping mechanism 6 for fixing the clamping column 5 is provided in the arc-shaped groove 203. Specifically, the clamping mechanism 6 includes a groove 601 provided on the collar and communicating with one side of the arc-shaped groove, a clamping block 602 slidably connected in the groove, and a spring 603 connected in the groove, one end of the spring 603 is connected to the bottom of the clamping block 602, and the top of the clamping block 602 is an inclined surface. The clamping column 5 squeezes the inclined surface of the clamping block 602 to make it completely hidden in the groove 601, and after the clamping column 5 completely passes through the clamping block 602, the clamping block 602 can press the clamping column 5 tightly in the arc-shaped groove 203. Fix the positioning sleeve 2 at the ends of the two pipes, then insert the two ends of the pipe body 1 into the two pipes, and insert the clamping column 5 into the corresponding arc groove 203, then rotate the turntable 4 to make the clamping column 5 rotate in the arc groove 203. During the rotation of the clamping column 5, the inclined surface of the clamping block 602 is squeezed, so that the clamping block 602 is completely hidden in the groove 601. When the clamping column 5 completely passes through the clamping block 602, the clamping block 602 pops outward under the action of the spring 603, and presses the clamping column 5 against the end wall of the arc groove 203, thereby completing the fixation of the turntable 4 and the positioning sleeve 2 (such as Figure 4 shown).
