[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-7 , the present invention provides a technical solution: a detachable rear cover for a plug cylinder of a strapping machine, including: a sealing component 2 for sealing the rear end of the plug cylinder, a positioning component 1 for facilitating the disassembly and assembly of the sealing component 2 is provided on one side of the sealing component 2, and the outside of the positioning component 1 is connected to the outside of the plug cylinder body 3.

[0025] The positioning component 1 includes: a fixed block 19, the outside of the fixed block 19 is fixedly connected to the outside of the plug cylinder body 3, an installation groove 15 and a slot 16 are opened at the top of the fixed block 19, the slot 16 is located on one side of the installation groove 15, the two sides of the gear 14 are rotatably connected to the groove wall of the installation groove 15, one end of the rotating handle 11 is fixedly connected to the outside of the gear 14, one end of the plug board 13 is fixedly connected to one side of the rotating handle 11, the outside of the plug board 13 is movably inserted into the slot 16, a positioning hole 12 is opened on the outside of the plug board 13, and a lock 110 is provided at the position of the positioning hole 12.

[0026] A through hole 17 is opened on one side of the fixed block 19, and the through hole 17 communicates with the slot 16. A cavity 18 is opened inside the fixed block 19, and the cavity 18 communicates with the installation groove 15.

[0027] Further, when it is necessary to remove the rear end cover 23 from the pin cylinder block 3, first pull the pull ring 115 in a direction away from the U-shaped plate 113. The pull ring 115 drives the pin rod 111 to move through the connecting rod 114, so that the pin rod 111 is withdrawn from the positioning hole 12. In this way, the insertion plate 13 can be removed from the insertion slot 16, and then the rotating handle 11 can be rotated. Then, rotate the rotating handle 11 in a direction away from the insertion slot 16. The rotating handle 11 drives the gear 14 to rotate. When the gear 14 rotates, it drives the tooth 21 and the connecting plate 22 to move, so that the connecting plate 22 moves in the direction of the rear end cover 23, and further the connecting plate 22 is withdrawn from the cavity 18, so as to realize the disassembly and separation of the rear end cover 23 and the pin cylinder block 3. The positioning component 1 makes the disassembly between the rear end cover 23 and the pin cylinder block 3 faster and more convenient, and the whole disassembly process does not require the use of bolts, effectively improving the disassembly efficiency of the rear end cover 23, so as to facilitate the maintenance of the pin cylinder.

[0028] The locking component 110 includes: a U-shaped plate 113, one side of the U-shaped plate 113 is fixedly connected to the side of the fixed block 19 and is located on one side of the through hole 17, and the other side of the U-shaped plate 113 is slidably sleeved on the outside of the connecting rod 114. One end of the connecting rod 114 is fixedly connected to the outside of the pull ring 115, the other end of the connecting rod 114 is fixedly connected to one end of the pin rod 111, and the outside of the pin rod 111 is slidably inserted into the through hole 17 and the positioning hole 12. The outside of the connecting rod 114 is slidably inserted into the inner ring of the spring 112, and both ends of the spring 112 are supported between the pin rod 111 and the U-shaped plate 113.

[0029] Further, when it is necessary to install the rear end cover 23 on the pin cylinder block 3, insert the connecting plate 22 into the cavity 18 so that the tooth 21 on the connecting plate 22 meshes with the gear 14. Then, rotate the rotating handle 11 in the direction of the insertion slot 16 so that the insertion plate 13 on the side of the rotating handle 11 is inserted into the insertion slot 16. The rotation of the rotating handle 11 drives the gear 14 to rotate, and the gear 14 drives the tooth 21 and the connecting plate 22 to move, so that the connecting plate 22 moves in a direction away from the rear end cover 23, and further the rear end cover 23 is tightly attached to the rear end of the pin cylinder block 3; then release the pull ring 115, and the spring 112 pushes the pin rod 111 into the through hole 17 and the positioning hole 12, so that the rotating handle 11 and the gear 14 cannot rotate, and further the connecting plate 22 cannot move in the cavity 18. Since then, the rear end cover 23 and the pin cylinder block 3 are completed for connection and installation.

[0030] The sealing component 2 includes: a rear end cover 23, a sealing ring 24 is provided on the inner ring of the rear end cover 23, one side of the rear end cover 23 is fixedly connected to one end of the connecting plate 22, and the outside of the connecting plate 22 is slidably inserted into the wall of the cavity 18. Teeth 21 are provided on the outside of the connecting plate 22, and the outside of the teeth 21 meshes with the outside of the gear 14.

[0031] Further, after the rear end cover 23 is tightly attached to the rear end of the latch cylinder block 3, a sealing ring 24 is provided between the rear end cover 23 and the latch cylinder block 3, and the sealing ring 24 can enhance the sealing performance between the rear end cover 23 and the latch cylinder block 3.

[0032] Working principle: When it is necessary to remove the rear end cover 23 from the latch cylinder block 3, first pull the pull ring 115 in a direction away from the U-shaped plate 113. The pull ring 115 drives the pin rod 111 to move through the connecting rod 114, so that the pin rod 111 is withdrawn from the positioning hole 12. In this way, the insertion plate 13 can be removed from the insertion slot 16, and then the rotating handle 11 can be rotated. Then rotate the rotating handle 11 in a direction away from the insertion slot 16. The rotating handle 11 drives the gear 14 to rotate. When the gear 14 rotates, it drives the teeth 21 and the connecting plate 22 to move, so that the connecting plate 22 moves in the direction of the rear end cover 23, and further makes the connecting plate 22 withdrawn from the cavity 18, so as to realize the disassembly and separation of the rear end cover 23 and the latch cylinder block 3.

[0033] When it is necessary to install the rear end cover 23 on the latch cylinder block 3, insert the connecting plate 22 into the cavity 18 so that the teeth 21 on the connecting plate 22 mesh with the gear 14. Then rotate the rotating handle 11 in the direction of the insertion slot 16, so that the insertion plate 13 on the side of the rotating handle 11 is inserted into the insertion slot 16. The rotation of the rotating handle 11 drives the gear 14 to rotate, and the gear 14 drives the teeth 21 and the connecting plate 22 to move, so that the connecting plate 22 moves in a direction away from the rear end cover 23, and further makes the rear end cover 23 tightly attached to the rear end of the latch cylinder block 3. Then release the pull ring 115, and the spring 112 pushes the pin rod 111 into the through hole 17 and the positioning hole 12. In this way, the rotating handle 11 and the gear 14 cannot rotate, and further the connecting plate 22 cannot move in the cavity 18. Since then, the connection and installation of the rear end cover 23 and the latch cylinder block 3 are completed.

[0034] As can be seen from the above, the positioning component 1 makes the disassembly and assembly between the rear end cover 23 and the latch cylinder block 3 more rapid and convenient, and the entire disassembly and assembly process does not require the use of bolts, effectively improving the disassembly and assembly efficiency of the rear end cover 23, so as to facilitate the maintenance of the latch cylinder.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
