[0027] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0029] As Figures 1-4 shown, the present utility model provides a new jig for solving the disassembly of the piston of the locking cylinder of a multi-cylinder crushing device, including a locking cylinder body 1 and a connecting rod 4. The inner wall of the locking cylinder body 1 is slidably connected with a piston body 2. A thread groove 3 is formed on the surface of the piston body 2. A threaded rod 5 is fixedly connected to the arc surface of the connecting rod 4. The size of the threaded rod 5 is adapted to the size of the thread groove 3. By providing the threaded rod 5 and the thread groove 3, when disassembling the locking cylinder body 1 and the piston body 2, the threaded rod 5 is inserted into the thread groove 3, and then by pulling the connecting rod 4, the piston body 2 can be slid out along the inner wall of the locking cylinder body 1 by using the threaded rod 5, so as to facilitate the disassembly of the locking cylinder body 1 and the piston body 2, and the locking cylinder body 1 and the piston body 2 will not be damaged during the disassembly process, improving the convenience during disassembly. The inner wall of the connecting rod 4 is slidably connected with an adjusting rod 6. One end of the adjusting rod 6 is fixedly connected with a handle 7. The movement of the handle 7 will drive the movement of the adjusting rod 6. The connecting rod 4 will drive the rotation of the threaded rod 5 by means of the movement of the adjusting rod 6.
[0030] As Figures 2-4As shown, the adjusting rod 6 has a regular hexagonal prism structure. The adjusting rod 6 with a regular hexagonal prism structure can conveniently drive the connecting rod 4 to move by using the handle 7. A pin 8 slides through the connecting rod 4. A jack 9 is formed on the surface of the adjusting rod 6. The size of the jack 9 is adapted to that of the jack 9. The number of jacks 9 is several. When the pin 8 is inserted into the jack 9, the pin 8 serves to limit the position of the adjusting rod 6, thereby limiting the position of the handle 7. A baffle 10 is fixedly connected to the arc surface of the connecting rod 4. A magnetic core 11 is embedded in the pin 8. The baffle 10 is an iron plate. The movement of the pin 8 will drive the movement of the magnetic core 11. When the magnetic core 11 abuts against the surface of the baffle 10, the magnetic core 11 will be attracted to the surface of the baffle 10. The baffle 10 serves to limit the position of the magnetic core 11, thereby limiting the position of the pin 8. A traction rope 12 is fixedly connected to the arc surface of the pin 8. One end of the traction rope 12 is fixedly connected to the connecting rod 4. After the pin 8 is pulled out of the jack 9, the traction rope 12 serves to prevent the pin 8 from being lost. A protective sleeve 13 is fixedly sleeved on the arc surface of the handle 7. The protective sleeve 13 is a rubber sleeve. The protective sleeve 13 serves to increase the friction force on the arc surface of the handle 7.
[0031] The overall working principle is as follows. When it is necessary to disassemble the locking cylinder body 1 and the piston body 2, align the threaded rod 5 with the thread groove 3, and then rotate the handle 7. At this time, the protective sleeve 13 serves to increase the friction force on the arc surface of the handle 7. The movement of the handle 7 will drive the movement of the adjusting rod 6. The connecting rod 4 will drive the threaded rod 5 to rotate by means of the movement of the adjusting rod 6. At this time, the adjusting rod 6 with a regular hexagonal prism structure can conveniently drive the connecting rod 4 to move by using the handle 7. The threaded rod 5 will be inserted into the thread groove 3 by means of the thread. After that, the handle 7 can be pulled in the direction away from the locking cylinder body 1. The adjusting rod 6 will pull the connecting rod 4 by means of the movement of the handle 7. The movement of the connecting rod 4 will drive the movement of the threaded rod 5. The movement of the threaded rod 5 can drive the piston body 2 to slide out from the inner wall of the locking cylinder body 1, so as to facilitate the disassembly of the locking cylinder body 1 and the piston body 2, and the locking cylinder body 1 and the piston body 2 will not be damaged during the disassembly process, improving the convenience during disassembly. When it is necessary to adjust the distance between the two handles 7, pull the pin 8 out of the jack 9. The traction rope 12 serves to prevent the pin 8 from being lost. Then move the adjusting rod 6 along the inner wall of the connecting rod 4. When the adjusting rod 6 moves to a suitable position, insert the pin 8 into the jack 9 again. The pin 8 serves to limit the position of the adjusting rod 6, thereby limiting the position of the handle 7. The movement of the pin 8 will drive the movement of the magnetic core 11. When the magnetic core 11 abuts against the surface of the baffle 10, the magnetic core 11 will be attracted to the surface of the baffle 10. The baffle 10 serves to limit the position of the magnetic core 11, thereby limiting the position of the pin 8. Therefore, the distance between the two handles 7 can be adjusted according to the stature of the staff, so as to facilitate the staff to screw the threaded rod 5 into the thread groove 3.
[0032] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
