Maintenance and repairs require a lot of time and manpower. At the same time, due to the complex connection between the piston and the inside of the cylinder, professional personnel are often required to operate it. The seals are easily damaged during the disassembly process, resulting in a decrease in sealing and an increased risk of equipment failure. Utility Model Content

[0026] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0027] Please refer to Figures 1 to 5 As shown, the utility model is a tensioning oil cylinder assembly with a piston that is easy to remove, including a tensioning oil cylinder assembly body 1, the interior of the tensioning oil cylinder assembly body 1 is vertically slidably connected to a piston body 3, the interior of the piston body 3 is provided with a mounting mechanism 5, the mounting mechanism 5 includes a sealing ring 501, a limiting plate 502, a connecting rod 503, a base 504, a gear 505, a rack 1 506, a rack 2 507, a slide rail 1 511, a slide rail 2 512, an arc plate 508, a locking rod 509 and a limiting member 510, a sealing ring 501 A gear 505 is provided inside, and rack 1 506 is meshed on both sides of the gear 505. Rack 2 507 is meshed on the front and back sides of the gear 505. A locking rod 509 is fixedly connected to the top of the gear 505. A limiter 510 is fixedly embedded in one end of the locking rod 509. The middle part of the locking rod 509 is rotatably connected to the limit plate 502. The bottom end of the gear 505 is rotatably connected to the connecting rod 503. The top of the base 504 is fixedly connected to two slide rails 1 511 and two slide rails 2 512.

[0028] An oil leakage detection mechanism 4 is provided inside the piston body 3. The oil leakage detection mechanism 4 includes a mounting plate 401, a mounting hole 402, a test paper ring 403 and a mounting rod 404. A plurality of mounting holes 402 are provided at the top of the piston body 3. The top of the mounting plate 401 is snap-connected with the test paper ring 403, and the bottom end of the mounting plate 401 is fixedly connected with a plurality of mounting rods 404. When the user needs to remove the piston body 3, the user can separate the connecting piece 2 from the tensioning cylinder assembly 1, and then the user can rotate the locking rod 509 to make the limit piece 510 disengage from the locking groove 513. As the locking rod 509 rotates, the locking rod 509 drives the gear 505 to rotate, and the gear 505 engages the two racks 1 506 and the two racks 2 507 to move respectively. The two racks 1 506 and the two racks 2 507 respectively drive multiple arc plates 508 to approach the gear 505. At this time, the multiple arc plates 508 no longer squeeze the sealing ring 501, and the user can easily remove the piston body 3. At the same time, the cooperation between the arc plates 508 and the sealing ring 501 avoids damage caused by direct pulling of the seal, thereby extending the service life of the seal. In conjunction with the oil leakage detection mechanism 4, when the user removes the piston body 3, the test paper ring 403 can be observed to see if there are any stains. If there are stains, it means that the sealing of the piston body 3 is poor and needs to be repaired and replaced in time.

[0029] Optionally, a connecting member 2 is rotatably connected to the inner wall of the piston body 3, and the top end of the connecting member 2 is rotatably connected to the inner wall of the tensioning cylinder assembly 1. In actual implementation, the connection between the piston body 3 and the cylinder assembly is made more flexible, allowing the piston body 3 to have a certain degree of rotational freedom during operation, thereby avoiding the stress concentration problems that may be caused by a rigid connection.

[0030] Optionally, the top end of the sealing ring 501 is fixedly connected to the bottom end of the piston body 3, and the bottom end of the sealing ring 501 is fixedly connected to the sealing head 6. In actual implementation, the cooperation between the sealing ring 501 and the sealing head 6 enhances the sealing performance of the piston body 3. The sealing ring 501 prevents liquid leakage, while the sealing head 6 strengthens the stability of the seal, ensuring that the fluid in the tensioner cylinder assembly body 1 does not leak under high-pressure operating conditions.

[0031] Optionally, one end of each of the two first racks 506 and one end of each of the two second racks 507 is fixedly connected to an arc plate 508, and the outer sides of the four arc plates 508 are all in contact with the inner side of the sealing ring 501. In actual implementation, the arc plates 508 are designed to fit the inner side of the sealing ring 501, so that during operation, the arc plates 508 can evenly apply pressure or release the sealing ring 501, ensuring a more stable and reliable sealing effect.

[0032] Optionally, the bottom ends of the two racks 506 are slidably connected to the top ends of the two slide rails 512, and the bottom ends of the two racks 507 are slidably connected to the top ends of the two slide rails 511. In actual implementation, the two slide rails 511 and the two slide rails 512 can improve the stability of the two racks 507 and the two racks 506.

[0033] Optionally, a locking groove 513 is defined in the middle of the stopper plate 502. The dimensions of the locking groove 513 match those of the stopper 510. The stopper plate 502 is fixedly connected to both sides of the inner wall of the piston body 3. In actual implementation, the precise matching of the locking groove 513 and the stopper 510 ensures the stability of the piston body 3 during operation, preventing the piston body 3 from shifting due to external vibration or pressure fluctuations.

[0034] Optionally, the bottom ends of the plurality of mounting rods 404 are inserted into the inner walls of the plurality of mounting holes 402. In actual implementation, the design of the mounting rods 404 and the mounting holes 402 ensures accurate positioning during component installation, which not only makes assembly more efficient but also reduces operation time.
