DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] With reference to Figures 1-5 , the utility model provides an embodiment: a pump body shell for oil pipeline convenient to disassemble, including pump body 1, the outside fixed connection of pump body 1 has connecting ring one 16, the outside of connecting ring one 16 is arranged in the inside of connecting ring two 17, the side fixed connection of connecting ring two 17 away from connecting ring one 16 has shell 2, the outside fixed connection of connecting ring two 17 has dismounting mechanism;

[0026] Dismounting mechanism includes installation box 6, the outside fixed connection of installation box 6 is in the outside of connecting ring two 17, the inside fixed connection of installation box 6 has spring 8, the end fixed connection of spring 8 away from installation box 6 has sliding plate 7, the side fixed connection of sliding plate 7 away from spring 8 has clamping block 9, the side fixed connection of sliding plate 7 away from clamping block 9 has moving rod 10, the end fixed connection of moving rod 10 away from sliding plate 7 has pulling plate 11, the outside of clamping block 9 is arranged in the inside of plug groove 5, plug groove 5 is arranged in the inside of plug block 4, plug block 4 is fixedly connected in the outside of connecting ring one 16, the outside of plug block 4 is arranged in the inside of clamping groove 15, clamping groove 15 is opened in the inside of connecting ring two 17, the outside sliding connection of sliding plate 7 is in the inside of installation box 6, the outside sliding connection of moving rod 10 is in the inside of installation box 6.

[0027] The pump body 1 is connected with the shell 2 through the connecting ring one 16 and the connecting ring two 17, the plug block 4 on the connecting ring one 16 is clamped in the inside of the clamping groove 15, and the clamping block 9 is matched with the plug slot 5 to limit the plug block 4, so that the plug block 4 is limited in the inside of the clamping groove 15, and the matching of the clamping block 9 and the plug slot 5 realizes the limiting function of the plug block 4, ensures the stability and safety of the device. The pull plate 11 drives the slide plate 7 and the clamping block 9 to move through the moving rod 10, and the moving rod 10 plays a role in connecting and transmitting force in the process. The slide plate 7 not only drives the movement of the spring 8 and the clamping block 9, but also ensures that the clamping block 9 can smoothly slide in the plug slot 5. The design of the plug slot 5 ensures that the clamping block 9 is accurately limited during movement, thereby effectively completing the disassembly and installation task.

[0028] Referring to Figure 2 and Figure 3 , the rotating disc 13 is rotatably connected to the side of the mounting box 6 away from the connecting ring two 17, the connecting rod 14 is fixedly connected to the side of the rotating disc 13 away from the mounting box 6, the limiting plate 3 is fixedly connected to the end of the connecting rod 14 away from the rotating disc 13, the side of the limiting plate 3 close to the mounting box 6 is in abutment with the pull plate 11, and the mounting plate 12 is fixedly connected to the side of the mounting box 6 away from the connecting ring two 17.

[0029] The rotating disc 13 is used to drive the rotation of the mounting connecting rod 14, and the connecting rod 14 plays a role in connecting the rotating disc 13 and the limiting plate 3. The main function of the limiting plate 3 is to limit the movement of the pull plate 11 to prevent unnecessary displacement, thereby ensuring the stability of the entire device. The mounting plate 12 is used to limit the movement trajectory of the limiting plate 3.

[0030] Working principle: when the shell 2 needs to be disassembled, first, pull the pull plate 11 to drive the moving rod 10, and with the movement of the moving rod 10, the slide plate 7 and the spring 8 move synchronously. The movement of the slide plate 7 further drives the clamping block 9, the clamping block 9 slides in the plug slot and is disconnected from the plug slot 5, the connection with the plug block 4 is released, and at the same time the plug block 4 is taken out from the inside of the clamping groove 15. Thus the shell 2 is smoothly taken out from the pump body 1. The disassembly process of the shell 2 is greatly simplified, avoiding the cumbersome operation in the traditional disassembly method. When the shell 2 needs to be reinstalled, pull the pull plate 11, reinstall the plug block 4 into the inside of the clamping groove 15, and loosen the pull plate 11, and use the elastic force of the spring 8 to push the slide plate 7 and the clamping block 9 to move, reset the clamping block 9 and accurately clamp it into the plug slot 5 of the plug block 4. This structure makes the disassembly and installation process of the shell 2 more smooth and fast, effectively improving the maintenance efficiency of the equipment.

[0031] Secondly, after the installation of the shell 2 is completed, by rotating the limiting plate 3, the limiting plate 3 drives the rotating disc 13 to rotate through the connecting rod 14, so that it is located outside the pulling plate 11, and the pulling plate 11 is effectively limited. This can prevent the pulling plate 11 from moving accidentally during use, avoid the clamping block 9 from exiting the slot 5, and ensure that the shell 2 will not be loose or unstable during work. Thus, the stability of the device connection is enhanced.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
