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.

[0021] Example 1

[0022] The utility model provides a butterfly valve which can be quickly assembled and disassembled. Figure 1-3 As shown, the butterfly valve that can be quickly assembled and disassembled includes a pipe body 1, a butterfly valve member 2 arranged on the pipe body 1, and mounting members 3 arranged at both ends of the pipe body 1; the mounting members 3 include fixed seats 31 symmetrically arranged at both ends of the pipe body 1, a clamping plate 32 that moves closer to or away from each other on the inner sides of the two fixed seats 31, and a locking member 33 arranged on the fixed seat 31 for locking the clamping plate 32; wherein the clamping plate 32 is in an arc shape that is adapted to the outer wall of the docking pipe.

[0023] When in use, the locking member 33 is driven to pull the two clamping plates 32 at the same end to slide away from each other on the fixing seat 31, and then the locking member 33 is driven again to place the pipe in the cavity of the pipe body 1. At the same time, the clamping plates 32 are pressed to slide towards each other on the fixing seat 31 to clamp and fix the pipe.

[0024] In order to prevent the clamping plate 32 from shifting during the sliding process, the two ends of the clamping plate 32 are slidably mounted on the two fixing seats 31 , respectively. The fixing seats 31 are provided with sliding grooves 311 corresponding to the ends of the clamping plate 32 .

[0025] Specifically, the locking member 33 includes a guide block 331 slidably installed in the slide groove 311 and connected to the end of the clamping plate 32, a handle 332 slidably installed on the side of the fixed seat 31 away from the tube body 1, abutment blocks 333 symmetrically arranged on the handle 332 for limiting the movement of the two guide blocks 331 away from each other, and a spring 334 arranged between the two abutment blocks 333, and the two ends of the spring 334 are respectively connected to the handle 332 and the side of the fixed seat 31 away from the tube body 1.

[0026] The pull handle 332 on the same side is pulled at the same time to drive the abutment block 333 to move on the fixed seat 31 until it is not in contact with the guide block 331 fixed on the end of the clamping plate 32, and the clamping plate 32 is pulled to slide along the slide groove 311 on the fixed seat 31 in a direction away from each other to release the pull handle 332, and the pull handle 332 moves to a position close to each other on the fixed seat 31 under the action of the spring 334, so as to place the pipe in the cavity of the pipe body 1, and at the same time, the clamping plate 32 on the same side is pressed to make the guide block 331 at the end of the clamping plate 32 abut against each other, and the pull handle 332 abuts against the side of the guide block 331 away from each other under the action of the spring 334 to fix the clamping plate 32, thereby clamping and fixing the pipe.

[0027] More specifically, one end of the guide block 331 away from the clamping plate 32 has a first inclined surface 3311 , and one end of the abutment block 333 away from the handle 332 has a second inclined surface 3331 matched with the first inclined surface 3311 .

[0028] When the clamping plate 32 is pressed to bring them closer to each other, the first inclined surface 3311 on the guide block 331 and the second inclined surface 3331 on the abutting block 333 abut against each other until the sides of the guide blocks 331 that are close to each other come into contact, and then the side of the abutting block 333 away from the second inclined surface 3331 abuts against the side of the guide block 331 away from the first inclined surface 3311.

[0029] It should be noted that the inner wall of the clamping plate 32 has a sealing strip 321 connected to the outer wall of the pipe body 1 and the butt pipe.
