Description

Technical Field

[0001] This utility model relates to a pump cover, and more particularly, to a pump cover structure. Background Technology

[0002] In existing pump cover structures, such as the pump cylinder cover disclosed in Chinese design patent with authorization announcement number CN3083429395S, its overall structure mainly includes a cover body, with water inlet holes and water outlet holes respectively provided on the front and rear sides of the cover body, and threaded holes are provided on the outer side wall of the cover body corresponding to the water inlet holes or water outlet holes.

[0003] The actual installation process for this type of pump cover is as follows: fit the docking cover against the outer wall of the cover body corresponding to the inlet or outlet hole, then pass the bolt through the docking cover and thread it into the threaded hole to fix the docking cover to the outer wall of the cover body.

[0004] However, the existing pump cover structure has the following technical defects: 1. If only threaded holes directly drilled into the cover are used for fixing, if the threaded holes strip during installation, the entire pump cylinder cover will lose its function and be scrapped, resulting in waste of resources and increased operating costs. 2. Although existing technologies employ embedded nuts to reduce the chance of stripping threads, the wall thickness of such pump cylinder covers is usually designed to be relatively limited. The thin wall thickness makes it difficult to form a stable and reliable fixation for the embedded nuts, causing the embedded nuts to loosen easily. This ultimately affects the connection stability between the mating cover and the cover body, and fails to meet the actual use requirements. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a pump cover structure that is easy to assemble and disassemble and has high connection stability.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A pump cover structure includes a cover body, the side of the cover body includes an exposed surface and a side cover surface, the side cover surface is provided with a water passage hole, the exposed surface is provided with a mounting groove, and the side cover surface is provided with a connecting hole, the connecting hole communicating with the mounting groove.

[0007] With the above technical solution, when it is necessary to connect the docking cover to the pump cover, the nut can be placed in the installation groove first, and then the docking cover can be attached to the side cover surface. The bolt passes through the docking cover and the connection hole in sequence, and finally the thread is connected to the nut, thereby realizing the connection between the pump cover and the docking cover. With the above connection method, even if the bolt and nut strip, only the bolt and nut need to be replaced. It will not be affected by the wall thickness. The overall disassembly and assembly are convenient and the connection stability is high.

[0008] Preferably, the mounting groove is provided with a protrusion.

[0009] Through the above technical solution, the protrusion can abut against the outer wall of the nut, thereby further restricting the circumferential rotation of the nut.

[0010] Preferably, there are two protrusions, with a gap between them.

[0011] Through the above technical solution, the nut can be confined to the space between the two protrusions, thereby providing more stable support for the entire nut.

[0012] Preferably, the mounting groove has a fixing groove on the groove wall opposite to the connecting hole.

[0013] With the above technical solution, after the bolt passes through the nut, it can pass through the fixing groove. On the one hand, the fixing groove can avoid the bolt; on the other hand, the width of the fixing groove can be controlled, thereby limiting the bolt laterally and improving the installation stability.

[0014] Preferably, the exposed surface is provided with reinforcing ribs.

[0015] Through the above technical solutions, the reinforcing ribs can strengthen the exposed surface and improve the structural stability of the pump cover.

[0016] Preferably, the water passage includes an inlet and an outlet, and the side cover has two holes, with the inlet and outlet located on two different side cover surfaces.

[0017] Through the above technical solution, the entire pump cover can simultaneously perform the functions of water outlet and water inlet, making it more versatile and compact in structure.

[0018] Preferably, the reinforcing rib includes a first rib, which is connected between the water inlet and the water outlet.

[0019] Through the above technical solution, the first rib can provide targeted structural reinforcement to the pump cover area corresponding to the water inlet and water outlet.

[0020] Preferably, the reinforcing rib includes a second annular rib, the center of which coincides with the center of the cover.

[0021] Through the above technical solution, the annular second rib can provide regional structural reinforcement to the pump casing.

[0022] Preferably, the reinforcing ribs include a third rib distributed radially, the length of which passes through the center of the cover.

[0023] Through the above technical solution, the radially distributed third ribs can further and effectively increase the overall structural strength of the pump casing. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.

[0027] A pump cover structure includes a cover body 1, the side of which includes an exposed surface 2 and a side cover surface 3. Two side cover surfaces 3 are provided and located on two opposite sides of the cover body 1.

[0028] The side cover 3 is provided with a water passage hole 4. In this embodiment, the water passage hole 4 includes a water inlet hole 41 and a water outlet hole 42, which are located on two side cover surfaces 3 respectively.

[0029] Connection holes 6 are also provided on the two side cover surfaces 3. In this embodiment, each side cover surface 3 has two connection holes 6, which are symmetrically distributed on both sides of the water passage hole 4.

[0030] An installation groove 5 is provided on the exposed surface 2, and the connecting hole 6 communicates with the installation groove 5.

[0031] The mounting groove 5 is provided with two protrusions 7, with a gap 8 between them.

[0032] A fixing groove 9 is provided on the groove wall of the mounting groove 5 opposite to the connecting hole 6.

[0034] The reinforcing rib 10 includes a first rib 101, a second rib 102, and a third rib 103. The first rib 101 connects the water inlet 41 and the water outlet 42. The second rib 102 is annular, and its center coincides with the center of the cover 1. The third rib 103 is radially distributed, and its length passes through the center of the cover 1.
