Embodiment
[0018] The pump cover of this embodiment is composed of two parts, that is, the fixing set 1 that can be fixed on the outer wall of the pump and the seal 2 used for sealing. More convenient, the equipment needs to customize a special fixing kit 1 and a seal 2 that meets the size of the pump body according to the size of the pump body.
[0019] Such as Figure 1-4 As shown, a pump cover that is easy to disassemble includes a fixing set 1 and a seal 2. The fixing set 1 includes symmetrically arranged fixing half-rings 101. The fixing half-rings 101 are fixedly connected by fixing bolts 102. The two fixing half-rings 101 The bottom of the outer wall is fixedly connected with a fixed piece 104 with a top opening, and the top of the outer wall of the two fixed half-rings 101 is connected with a first pressing arm 107 and a second pressing arm 108 through a connecting shaft 106. The first pressing arm 107 and the second pressing arm The bottom of the arm 108 is fixedly connected wi...

The invention discloses a pump cover convenient to disassemble, and relates to the technical field of pump body parts. The pump cover convenient to disassemble comprises a fixed sleeve piece and a sealing piece, the fixed sleeve piece comprises symmetrically-arranged fixed half rings, the fixed half rings are fixedly connected through fixing bolts, the bottoms of the outer walls of the two fixed half rings are fixedly connected with fixed pieces, the tops of the fixing pieces are provided with holes, the tops of the outer walls of the two fixed half rings are rotationally connected with a first pressing arm and a second pressing arm through connecting rotating shafts respectively, the bottoms of the first pressing arm and the second pressing arm are fixedly connected with symmetrically-arranged pressing blocks correspondingly, and the bottoms of the pressing blocks make contact with the top of the sealing piece. According to the pump cover, through the arranged fixed sleeve part, the pump cover is fixed to the outer wall of a pump body in advance, then the sealing piece is compacted and sealed on the pump body by utilizing the first pressing arm and the second pressing arm of the fixed sleeve piece and in cooperation with the extrusion effect of the pressing blocks, and therefore only two fastening bolts need to be opened during disassembly, and compared with a traditional pump cover, disassembly is more convenient and faster.
Description
technical field [0001] The invention relates to the technical field of pump body components, in particular to a pump cover that is easy to disassemble. Background technique [0002] The pump cover is a key part to realize the sealing inside the pump body. When it is used in a vacuum pump or an oil pump, the sealing requirements are relatively strict, and it is one of the important parts to ensure the work of the pump body. [0003] Patent application publication number: CN207813908U discloses a pump cover that is easy to disassemble and install. It is fixed by multiple bolts. It has a compact structure and is easy to use. It is safe and reliable for cleaning, inspection and maintenance, has good economic and social benefits, and is suitable for popularization and use. [0004] However, when the pump cover is disassembled in the above-mentioned patent, it is still necessary to disassemble a plurality of bolts to open the pump cover, and the convenience of disassembly and ins...
