During the installation and disassembly process, a lot of time is spent on the bolt loading and unloading operations. This is especially inconvenient when there are many bolts or when the installation space is narrow. This not only reduces the efficiency of disassembly and assembly but also increases the workload of maintenance personnel. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to a quick-release oil pump cover structure, including a pump body 1, a cover 3 on the top of the pump body 1, an installation mechanism 2 between the cover 3 and the pump body 1, and a rubber ring 4 fixedly connected to the bottom of the cover 3, the rubber ring 4 being in contact with the pump body 1.

[0025] Specifically, by Figure 2-4 The installation mechanism 2 includes two positioning frames 201 symmetrically fixed to the top of the cover 3. A round rod 204 is fixedly connected between the two positioning frames 201. Two sliders 207 are symmetrically and movably sleeved on the outer side of the round rod 204. An insert rod 206 is fixedly connected to the top of each slider 207. Two positioning plates 202 are symmetrically and fixedly connected to the top of the pump body 1. The cover 3 is movably sleeved on the outer side of the two positioning plates 202, and the two positioning frames 201 are respectively sleeved on the outer side of the two positioning plates 202. An insertion hole 208 is provided on the side of the two positioning plates 202 that are close to each other. The two insert rods 206... 6 are inserted into two sockets 208 respectively. A lifting frame 205 is movably sleeved on the outside of the round rod 204. A grip 209 is fixedly connected to the inside of the lifting frame 205. Two movable rods 203 are symmetrically rotatably connected to the outside of the lifting frame 205. The ends of the two movable rods 203 away from the lifting frame 205 are rotatably connected to the top of the two sliders 207 respectively. A sleeve plate 2012 is fixedly sleeved on the outside of the round rod 204. Two springs 2010 are symmetrically fixedly connected between the top of the sleeve plate 2012 and the bottom of the lifting frame 205. Both springs 2010 are sleeved on the outside of the round rod 204.

[0026] In use, first hold the handle 209 and the round rod 204, causing the lifting frame 205 to slide upward along the round rod 204. At this time, both springs 2010 are stretched, and through the two movable rods 203, the two sliders 207 slide along the round rod 204 respectively. At the same time, the two insertion rods 206 move closer to each other. Then, the cover 3 is placed on the outside of the two positioning plates 202 and located on the top of the pump body 1, while the two positioning frames 201 are respectively placed on the outside of the two positioning plates 202. Then, release the handle 209 and the round rod 204. At this time, the two springs 2010 return to their original position, causing the lifting frame 205 to slide downward along the round rod 204, so that the two insertion rods 206 move away from each other until they are inserted into the two insertion holes 208 respectively, thus fixing the cover 3. When the handle 209 and the round rod 204 are held again, the two insertion rods 206 are disengaged from the two insertion holes 208 respectively, releasing the fixation of the cover 3. Finally, the cover 3 can be quickly disassembled and assembled.

[0027] Specifically, by Figure 5 As shown, a first half-screw 2014 is fixedly connected to the top of the sleeve plate 2012, a top block 2011 is fixedly connected to the top of the first half-screw 2014, the bottom of the lifting frame 205 abuts against the top of the top block 2011, a second half-screw 2015 is fixedly connected to the bottom of the lifting frame 205, the second half-screw 2015 is in contact with the first half-screw 2014, a screw cylinder 2016 is provided between the first half-screw 2014 and the second half-screw 2015, the screw cylinder 2016 abuts against the bottom of the top block 2011, a plurality of auxiliary handles 2013 are fixedly connected at equal angles on the outer side of the screw cylinder 2016, the external threads of the first half-screw 2014 and the second half-screw 2015 are matched with the internal threads of the screw cylinder 2016, and the screw cylinder 2016 is threadedly sleeved on the outer side of the first half-screw 2014 and the second half-screw 2015;

[0028] In the initial state, the screw barrel 2016 is threaded onto the outside of the first half-screw 2014. When the lifting frame 205 slides down along the round rod 204, causing the two insert rods 206 to be inserted into the two insertion holes 208 respectively, the lifting frame 205 abuts against the top block 2011, while the second half-screw 2015 and the first half-screw 2014 are in contact with each other. Then, the auxiliary handle 2013 is rotated, causing the screw barrel 2016 to rotate on the outside of the first half-screw 2014, so that the screw barrel 2016 rises and is threaded onto the outside of the second half-screw 2015, until the screw barrel 2016 abuts against the top block 2011, fixing the lifting frame 205 and the sleeve plate 2012, thus limiting the lifting frame 205 to prevent the two insert rods 206 from loosening, and finally ensuring the stability of the cover 3.
