Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water pumps and relates to a submersible pump. Background Art
[0002] At present, the outlet port pipeline of the submersible pump is integrally formed and cannot be adapted to external pipelines of multiple different specifications. Submersible pumps with different specifications of outlet ports are equipped for different specifications of external pipelines. Therefore, the cost for users will be very high. Summary of the Invention
[0003] The purpose of the utility model is to provide a new type of submersible pump that can be adapted to external pipelines of different specifications for the above problems existing in the prior art.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A submersible pump includes a pump body. It is characterized in that an outlet seat extends outward from the pump body and is formed at the top position. The outlet seat has internal threads. An outlet pipeline is threadedly connected to the outlet seat. A sealing structure is provided between the outlet pipeline and the outlet seat.
[0005] In the above-mentioned submersible pump, the sealing structure is composed of a sealing body and sealing lips formed at the upper and lower ends of the sealing body. The outer end of the sealing body has an extending portion extending outward, and the top of the extending portion has a surrounding portion that bends and extends. A sealing protrusion is formed at the inner end of the surrounding portion. Sealing grooves for receiving the corresponding sealing lips are provided at the top of the outlet seat and the bottom of the outlet pipeline. A clamping groove for the sealing protrusion to be clamped into is provided on the outer circle of the outlet pipeline.
[0006] Compared with the prior art, the submersible pump of the utility model has the advantage of strong versatility. Brief Description of the Drawings
[0007] Figure 1 is a perspective view of the submersible pump.
[0008] Figure 2 is a partial cross-sectional view of the submersible pump.
[0009] In the figure, 1, pump body; 2, outlet seat; 3, outlet pipeline; 4, sealing body; 5, sealing lip; 6, extending portion; 7, surrounding portion; 8, sealing protrusion. Detailed Description of the Embodiments
[0010] The following are specific embodiments of the utility model in combination with the drawings. The technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.
[0011] Such as Figure 1 、 Figure 2As shown in the figure, this submersible pump includes a pump body 1. An outlet seat 2 extends outward from the pump body 1 and is formed at the top position. The outlet seat 2 has an internal thread. A water outlet pipe 3 is threadedly connected to the outlet seat 2. The water outlet pipe 3 is connected by threads and can be disassembled and assembled. The port of the water outlet pipe 3 can be designed with different diameters to meet different specifications of external pipes. A sealing structure is provided between the water outlet pipe 3 and the outlet seat 2.
[0012] Specifically, the sealing structure is composed of a sealing body 4 and sealing lips 5 formed at the upper and lower ends of the sealing body 4. The outer end of the sealing body 4 has an extension part 6 extending outward, and the top of the extension part 6 has a bent and extended surrounding part 7. A sealing protrusion 8 is formed at the inner end of the surrounding part 7. Sealing grooves for the corresponding sealing lips 5 to access are provided at the top of the outlet seat 2 and the bottom of the water outlet pipe 3. A clamping groove for the sealing protrusion 8 to be inserted into is provided on the outer circle of the water outlet pipe 3. When replacing the water outlet pipe 3, the sealing protrusion 8 is peeled off from the clamping groove, and then the water outlet pipe 3 is taken out; the formation of the sealing lips 5 greatly improves the sealing performance of the sealing structure; and the formation of the sealing protrusion 8 can position the sealing structure well and will not shift, and the sealing stability is better.
[0013] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0014] Although terms such as pump body 1, outlet seat 2, water outlet pipe 3, sealing body 4, sealing lips 5, extension part 6, surrounding part 7, sealing protrusion 8, etc. are used more in this article, the possibility of using other terms is not excluded. Using these terms is only for more convenient description and explanation of the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
