Description

Technical Field

[0001] The utility model relates to a quick-release joint, in particular to a quick-release joint for a coal mine water pipeline, belonging to the technical field of coal mines. Background Art

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into two types: underground coal mines and open-pit coal mines. When the coal seam is far from the surface, the coal is usually extracted by tunneling underground. This type of mine is called an underground coal mine. When the coal seam is close to the surface, the coal is directly extracted by removing the surface soil layer. This type of mine is called an open-pit coal mine.

[0003] After searching, a Chinese patent application with publication number CN211315402U discloses a water pipe joint comprising a gland, a retractable elastic ring, a joint body, and a connecting portion disposed on the joint body. During use, one end of the water pipe is first placed on the joint, the elastic ring is then placed on the water pipe, and the gland is then placed around the elastic ring and secured to the connecting portion. As the gland and connecting portion are gradually connected, the elastic ring gradually tightens the water pipe to the joint under the action of the gland. Compared to existing water pipe joints, this has the advantages of simple structure, ease of use, and excellent sealing.

[0004] Although the above solution has the advantages of simple structure, easy use, and good sealing effect, it is difficult to enhance the stability of the water pipe joints in the above patent. The connected joints are often pulled and moved in the mine due to external forces, which can easily cause disconnection or leakage at the connection. To this end, we provide a coal mine water pipeline quick-release joint to solve the above problems. Utility Model Content

[0024] The embodiment of the utility model provides a quick-release joint for a coal mine water pipeline.

[0025] See also Figure 1 and Figure 4 , including a quick-release connector 1 and a quick-release connector 2. The inner wall of the quick-release connector 2 is connected with a sealing ring 2 16. The sealing ring 2 16 contacts the limiting insert 14. The purpose of providing the sealing ring 2 16 is to effectively seal the gap between the limiting insert 14 and the quick-release connector 2 2 to ensure that no liquid seepage occurs and to ensure water circulation.

[0026] See also Figure 3 and Figure 4 The quick-release connector 1 is fixedly connected to the threaded barrel 13. The outer circumferential surface of the threaded barrel 13 is provided with a thread. The setting of the threaded barrel 13 can effectively cooperate with the subsequent threaded groove 9, thereby ensuring the quick-release connector 1 and the quick-release connector 2 2 to be quickly disassembled and assembled, and ensuring the stability of the quick-release connector 1 and the quick-release connector 2 2 after installation.

[0027] See also Figure 1 、 Figure 2 and Figure 3 The quick-release connector 1 is connected to the water pipe 2 12, and the quick-release connector 1 is fixedly connected to the limiting insert 14. The setting of the limiting insert 14 can effectively exert a position control effect to ensure that water does not enter the threaded connection and rust will not occur, which is convenient for dismantling operations after use. The quick-release connector 2 2 is connected to the water pipe 10, and the outer circumferential surface of the quick-release connector 2 2 is fixedly connected with anti-slip grooves 11. The setting of the anti-slip grooves 11 makes it convenient for staff to twist the quick-release connector 1 and the quick-release connector 2 2 without slipping, thereby enhancing its practical effect.

[0028] See also Figure 2 and Figure 4 The inner wall of the quick-release joint 2 is fixedly connected with a position-controlling cylinder 8, and the outer circumferential surface of the position-controlling cylinder 8 is sleeved with a sealing ring 15. The setting of the position-controlling cylinder 8 further enhances the water-blocking effect and realizes a limiting effect on the sealing ring 15 to avoid the dislocation of the sealing ring 15. The sealing ring 15 contacts the threaded cylinder 13. The setting of the sealing ring 15 can effectively seal the gap between the threaded cylinder 13 and the quick-release joint 2, thereby enhancing the sealing effect of the joint.

[0029] See also Figure 2 、 Figure 3 and Figure 4 A threaded groove 9 is provided on the inner wall of the quick-release joint 2. The quick-release joint 2 is rotatably connected to the movable control plate 3. A restricted block 4 is fixedly connected to one side of the movable control plate 3. The movable control plate 3 and the restricted block 4 maintain a linkage effect. The restricted block 4 can cooperate with the restricting block 6 to form a mutual restriction effect, thereby ensuring the stability of the movable control plate 3.

[0030] See also Figure 3 and Figure 4 The inner wall of the quick-release joint 1 is slidably connected to an external push rod 5. The setting of the external push rod 5 is convenient for the staff to operate and freely displace the limiting block 6. One end of the external push rod 5 is fixedly connected to the limiting block 6.

[0031] See also Figure 4 The limiting block 6 is fixedly connected to the tough spring 7, and the tough spring 7 is fixedly connected to the quick-release joint 1. The purpose of setting the tough spring 7 is to utilize the elasticity of the tough spring 7 itself to effectively reset the limiting block 6 and make the limiting block 6 limit the limiting block 4 to ensure that the limiting block 4 will not be separated, so that the quick-release joint 1 and the quick-release joint 2 will not rotate at will, avoiding the quick-release joint 1 and the quick-release joint 2 from being disconnected or leaking.

[0032] Working principle: The external push rod 5 is pressed by external force, so that the external push rod 5 slides in the quick-release joint 1, driving the limiting block 6 to compress the tough spring 7, so that the tough spring 7 is in a contracted state, thereby releasing the restriction of the limiting block 6 on the limiting block 4, and again using external force to rotate the movable control plate 3 together with the limiting block 4 with the intersection with the quick-release joint 2 2 as the origin, and then hold the quick-release joint 1 and the quick-release joint 2 with both hands respectively, and twist the quick-release joint 1 and the quick-release joint 2 in opposite directions to separate the quick-release joint 1 and the quick-release joint 2, thereby achieving the effect of quickly disassembling the water supply pipe 10 and the water supply pipe 2 12. When the quick-release joint 1 and the quick-release joint 2 are connected, the threaded cylinder 13 presses the sealing ring 15, and the limiting insert 14 presses the sealing ring 2 16, so that the sealing ring 15 and the sealing ring 2 16 are deformed, thereby playing the effect of sealing the gap between the components and ensuring the smooth flow of water.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
