[0025] Embodiment

[0026] The specific embodiment of the utility model as Figs. 1-2 Indicated, an oil tank valve disassembling device, including coaxial setting on the workbench on the base 5 and valve screwing piece 1. Among them, the valve screwing piece 1 is close to the base 5 side and is equipped with the connecting pipe 12 that can be detachably positioned and connected with the oil tank valve 3, and the valve screwing piece 1 is equipped with the screw rod part 11 coaxial with the connecting pipe 12 away from the base 5 side. The workbench is also provided with the installation pipe that is screwed with the screw rod part 11. In the embodiment, the oil tank 4 is installed between the base 5 and the valve screwing piece 1, and the base 5, the oil tank 4, the oil tank valve 3, the connecting pipe 12, the valve screwing piece 1 and the screw rod part 11 are all on the same axis.

[0027] When the oil tank valve 3 is disassembled through the device, first, the valve screwing piece 1 is twisted forward, the valve screwing piece 1 is moved away from the base 5 side through the screw thread cooperation between the screw rod part 11 and the installation pipe, thereby reserving the operation space for the positioning and installation of the oil tank 4 on the base 5. Then, after the oil tank 4 is positioned and installed on the base 5, the valve screwing piece 1 is twisted reversely again, moves to the side close to the base 5, and completes the detachable positioning and connection between the connecting pipe 12 and the oil tank valve 3. Finally, the valve screwing piece 1 is twisted forward again, realizes the synchronous rotation with the oil tank valve 3, and in the process, the oil tank valve 3 is disassembled from the oil tank 4 through the screw thread step cooperation between the screw rod part 11 and the workbench installation pipe, and the oil tank valve 3 is also prevented from freely popping out.

[0028] Therefore, the device is convenient to use, can efficiently complete the disassembly of the oil tank valve 3 while avoiding the oil tank valve 3 from being ejected to injure people, thereby effectively solving the safety problem of disassembling the oil tank 4. Moreover, through the device, the disassembly process of the oil tank valve 3 is controllable, avoiding the oil tank valve 3 from being abruptly ejected by the spring, thereby effectively protecting the parts from being damaged during the disassembly process, controlling the quality stability and reliability of the oil tank 4 maintenance. In addition, the device can be used not only for the disassembly process of the oil tank valve 3, but also for the assembly process of the oil tank valve 3, one set of device with two purposes, greatly improving its use.

[0029] Regarding the specific structure of the base 5: the base 5 includes a positioning installation pipe 51 which is detachably positioned and sleeved with the outer wall of the oil tank 4. In use, the oil tank 4 is inserted into the positioning installation pipe 51 to realize the positioning and installation of the oil tank 4. Moreover, during use, since the spring inside the oil tank 4 is always in a compressed state, the elastic force of the spring will act on the oil tank 4 itself as well as the oil tank valve 3, thereby being able to provide a compression force to the oil tank 4 towards the base 5, thereby avoiding the oil tank 4 from moving randomly to affect the disassembly of the oil tank valve 3.

[0030] In this embodiment, the positioning installation pipe 51 is fixedly installed on the workbench through the base plate 52 provided on the outer wall thereof. The outer wall of the positioning installation pipe 51 and the plate surface of the base plate 52 are connected by welding.

[0031] In order to realize the detachable positioning connection between the connecting pipe 12 and the oil tank valve 3, the valve fixing shaft 31 is fixedly arranged on the oil tank valve 3, and the connecting pipe 12 is detachably and rotatably sleeved with the valve fixing shaft 31 fixedly arranged on the oil tank valve 3. At the same time, in order to enable the oil tank valve 3 to rotate synchronously when the valve rotating part 1 is screwed, the connecting pin 2 which penetrates through the side wall of the connecting pipe 12 and extends into the valve fixing shaft 31 is detachably inserted into the connecting pipe 12.

[0032] In this embodiment, in order to realize quick positioning between the connecting pipe 12 and the valve fixing shaft 31 conveniently and quickly, a plurality of pin holes 21 which are detachably inserted and matched with the connecting pin 2 are arranged on the side walls of the connecting pipe 12 and the valve fixing shaft 31. In this way, only one set of pin holes 21 needs to be aligned, and then the positioning and sleeving of the two can be realized quickly through the connecting pin 2.

[0033] Therefore, in this embodiment, four pin holes 21 which are arranged around the axis of the connecting pipe 12 are arranged on the side wall of the connecting pipe 12, and four pin holes 21 which are arranged around the axis of the valve fixing shaft 31 are arranged on the side wall of the valve fixing shaft 31. Moreover, the diameter of the pin hole 21 is slightly larger than the outer diameter of the connecting pin 2, thereby facilitating the insertion of the connecting pin 2 and the alignment of the connecting pin 2. In addition, in order to facilitate the insertion of the connecting pin 2 by the worker, the connecting pin 2 is an L-shaped pin.

[0034] The utility model is described above in combination with the best embodiment, but the utility model is not limited to the above disclosed embodiment, and should cover various modifications, equivalent combinations according to the essence of the utility model.
