Description

Technical Field

[0001] The utility model relates to the technical field of pump covers, in particular to a pump cover which is easy to disassemble. Background Art

[0002] In the industrial and civil fields, pumps are widely used in the process of conveying various media such as liquids, gases and powders. As one of the important parts of the pump, the structural design of the pump cover directly affects the safety, reliability and maintenance efficiency of the pump. However, in the past designs, the removal of the pump cover often faced many challenges, such as too many fixings, complicated operation, and difficult removal, which affected the maintenance and repair efficiency of the equipment.

[0003] After searching, the existing patent (Announcement No.: CN220118389U) discloses a pump cover that is easy to disassemble, including a pump body, a pump cover, a support frame, a threaded column and a pressure block, the pump cover is movably connected to the top of the pump body, the support frame is fixedly connected to the top of the pump body, the threaded column is threadedly connected to the top of the support frame, the pressure block is fixedly connected to the bottom of the threaded column, the pressure block is movably connected to the pump cover, the top of the threaded column is fixedly connected to a mounting rod, and the top of the support frame is fixedly connected to a positioning ring. The utility model provides a positioning ring so that the positioning ring cooperates with the mounting rod to position the threaded column, which solves the problem that the pressure block is driven to move downward by the threaded column during use, so that the pressure block can install the pump cover, but the pump body will vibrate when in use, and the device is not provided with a positioning structure, resulting in the threaded column becoming loose after long-term use, thereby affecting the fixation of the pump cover.

[0004] However, in the actual use of the above solution, no sealing structure is provided in the device, and the lack of a sealing structure means that there may be a gap or crack in the connection between the pump cover and the pump body, which may easily lead to liquid or gas leakage. This will reduce the working efficiency of the pump and even cause environmental pollution or equipment damage.

[0005] In view of this, the utility model provides a pump cover that is easy to disassemble. Utility Model Content

[0013] Preferably, the limit block is snap-connected to the host cover.

[0014] Preferably, the threaded sleeve is threadedly connected to the connecting sleeve, and the threaded sleeve is slidably connected to the limiting sleeve.

[0015] The working principle and beneficial effects of the utility model are:

[0016] In the utility model, by rotating the quick-release bolt, the quick-release bolt is limited by the limit nut, forcing the quick-release bolt to move downward, so that the sealing ring is squeezed by the pressing plate, so that the sealing ring and the second groove are more closely fitted, which can effectively prevent liquid or gas from leaking from the contact surface between the pump cover and the pump body, ensure the sealing performance of the pump during operation, and reduce the risk of environmental pollution and waste of resources;

[0017] In the utility model, the connecting sleeve and the threaded sleeve cooperate with each other to drive the limit block to move downward, thereby driving the limit ring to move downward synchronously, thereby squeezing the limit ball, forcing the limit ball to move inward and engage with the first slot to fix the fixing rod and the limit sleeve. At the same time, the main engine cover is engaged with the limit block to fix the main engine cover and the main engine connecting plate, completing rapid installation. Conversely, rapid disassembly can be performed, and the pump cover can be removed from the pump body more quickly, saving maintenance and repair time, improving equipment availability and production efficiency, and the quick disassembly design simplifies the disassembly process, reduces the operating difficulty and labor intensity of the operator, reduces labor costs, and reduces accidental damage caused by operating errors.
