Sealing barb parts are annularly formed at the upper end and the lower end of the inner wall of the sealing structure, the sealing barb parts are arranged in a curved shape, and the sealing barb parts abut against the pump body to form pressing sealing. The sealing structure has the advantage that the sealing performance is improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps and relates to a deep well pump, in particular to a novel deep well pump. Background Art

[0002] Currently, deep well pumps on the market are equipped with filters to prevent impurities in the water from entering the pump body and causing structural wear and damage. However, there is a lack of a sealing structure between the filter and the pump body, which allows small particles in the water to enter the pump body, affecting its use. Summary of the Invention

[0003] The purpose of the utility model is to provide a new deep well pump to solve the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a new deep well pump, comprising a pump body and a filter cover arranged on the pump body, characterized in that a sealing structure is installed between the upper and lower ends of the filter cover and the pump body, and the positions on the pump body for installing the sealing structure are provided with a plurality of guide columns, the sealing structure has a guide groove installed on the guide column, the upper and lower ends of the inner wall of the sealing structure are annularly formed with a sealing hook portion, and the sealing hook portion is curved, the sealing hook portion abuts against the pump body and forms a compression seal.

[0005] In the above-mentioned novel deep well pump, the filter cover is mounted on the pump body by screws, and the screws are staggered with the guide column.

[0006] Compared with the prior art, the novel deep well pump has the advantage of improving the overall sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a three-dimensional diagram of the new deep well pump.

[0008] Figure 2 It is a partial cross-sectional view of the new deep well pump.

[0009] In the figure, 1. pump body; 2. filter cover; 3. sealing structure; 4. guide column; 5. sealing hook part; 6. screw. DETAILED DESCRIPTION

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1 、 Figure 2As shown, the new deep well pump includes a pump body 1 and a filter cover 2 arranged on the pump body 1, and a sealing structure 3 is installed between the upper and lower ends of the filter cover 2 and the pump body 1, and the positions for installing the sealing structure 3 on the pump body 1 are provided with a plurality of guide columns 4, and the sealing structure 3 has a guide groove installed on the guide column 4, which plays a role in radial positioning, and the upper and lower ends of the inner wall of the sealing structure 3 are annularly formed with sealing hook portions 5, and the sealing hook portions 5 are curved. The sealing hook portions 5 abut against the pump body 1 and form a compression seal. During installation, the sealing structure 3 is inserted into the guide column 4, and the sealing hook portions 5 abut against the corresponding installation surface of the pump body 1 and form extrusion, thereby achieving a compression seal after installation.

[0012] Preferably, the filter cover 2 is mounted on the pump body 1 by means of screws 6 , and the screws 6 are staggered with the guide posts 4 .

[0013] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0014] Although this document frequently uses terms such as pump body 1, filter housing 2, sealing structure 3, guide post 4, sealing barb 5, and screw 6, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
