Description

Technical Field

[0001] The utility model belongs to the technical field of pumps, in particular to a pump which is convenient for connection and fixing. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] When the water pump is transporting water, foreign matter in the water will enter the water pump along with the water, causing damage to the water pump. The existing solution is to set a filter inside the water pump to filter the water, but these foreign matter will still accumulate on the filter. If it is not cleaned in time, it will cause the water inlet pipe to be blocked for a long time, affecting the use of the water pump. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a pump which is easy to connect and fix, and solves the problem that the filter screen on the existing water pump, if not cleaned in time, will cause the water inlet pipe to be blocked for a long time, thus affecting the use of the water pump.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pump that is easy to connect and fix, comprising a water pump, the water pump is provided with a water inlet, the water inlet is provided with a first flange, a threaded barrel is fixedly connected to the first flange, an internally threaded pipe is threadedly connected to the threaded barrel, a support ring is fixedly connected to the inside of the internally threaded pipe, a connecting frame is provided inside the internally threaded pipe, a filter is provided on the connecting frame, and the connecting frame is overlapped on one side of the support ring.

[0006] As a further solution of the utility model: a rear cover is arranged on the water pump, and a plurality of heat dissipation holes are opened on the rear cover.

[0007] As a further solution of the utility model: a bracket is fixedly connected to the bottom of the water pump, and four self-locking universal wheels are arranged at the bottom of the bracket.

[0008] As a further solution of the utility model: a water outlet is provided on the water pump, and a second flange is fixedly connected to the internally threaded pipe.

[0009] As a further solution of the utility model: a plurality of handles are fixedly connected to the internally threaded tube, and a filter plate is arranged inside the rear cover.

[0010] As a further solution of the utility model: a plurality of through holes are provided on the filter plate, and a plurality of bolts are provided on the first flange.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The pump which is easy to connect and fix is ​​provided with a support ring, an internally threaded pipe, a filter screen and a threaded barrel. When the filter screen needs to be disassembled, the handle is turned to disengage the internally threaded pipe from the threaded barrel, thereby taking out the connection frame. At this time, the filter screen and the internally threaded pipe can be cleaned. When the connection frame needs to be installed, the connection frame is first placed on the support ring, and the support ring supports the connection frame. At this time, the internally threaded pipe is screwed onto the threaded barrel, and the connection frame and the filter screen are connected and fixed. The water pump is easy to connect, fix and disassemble the filter screen, so that the filter screen can be cleaned in time to avoid clogging of the filter screen.

[0013] 2. The pump is easy to connect and fix. By setting the heat dissipation holes, the filter plate, the through hole and the water pump, the heat generated by the water pump when in use can be dissipated through the heat dissipation holes to avoid damage to the water pump caused by excessive heat. By setting the filter plate, foreign matter can be prevented from entering the water pump. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a pump that is easy to connect and fix, including a water pump 1, a water inlet 6 is arranged on the water pump 1, a back cover 2 is arranged on the water pump 1, and a plurality of heat dissipation holes 3 are opened on the back cover 2.

[0020] A first flange 8 is provided on the water inlet 6. Due to the provision of the first flange 8 and the cooperation with the bolts 18, when the threaded barrel 14 is rusted, the bolts 18 can be removed to replace the threaded barrel 14, thereby improving practicality. The first flange 8 is fixedly connected to the threaded barrel 14, and the threaded barrel 14 is threadedly connected to an internal threaded tube 9, and the internal threaded tube 9 is fixedly connected to a plurality of handles 12. Due to the provision of the handles 12, the handles 12 make the internal threaded tube 9 easier to be rotated, thereby improving the convenience of operation. At the same time, the handles 12 are designed as an arc surface, which makes it more comfortable for people to hold. A filter plate 17 is provided inside the rear cover 2.

[0021] A support ring 11 is fixedly connected inside the internal threaded pipe 9 , a connection frame 15 is provided inside the internal threaded pipe 9 , a water outlet 7 is provided on the water pump 1 , and a second flange 10 is fixedly connected to the internal threaded pipe 9 .

[0022] A filter screen 13 is provided on the connecting frame 15. Due to the provision of the filter screen 13, the filter screen 13 can filter foreign matter in the water to prevent foreign matter from entering the water pump 1 and causing damage to the water pump 1, thereby protecting the water pump 1. The connecting frame 15 is overlapped on one side of the support ring 11. A bracket 4 is fixedly connected to the bottom of the water pump 1. Four self-locking universal wheels 5 are provided at the bottom of the bracket 4. Due to the provision of the self-locking universal wheels 5, when the water pump 1 is transported, the self-locking universal wheels 5 can roll on the ground to reduce friction, facilitate the transportation of the water pump 1, and reduce manual labor intensity. At the same time, by locking the self-locking universal wheels 5, the stability of the water pump 1 during operation can be ensured. A plurality of through holes 16 are provided on the filter plate 17, and a plurality of bolts 18 are provided on the first flange 8.

[0023] The working principle of the utility model is:

[0024] Connect the water pipe through the second flange 10, start the water pump 1, and when water enters the internal threaded tube 9, foreign matter in the water is filtered by the filter screen 13. When the filter screen 13 needs to be disassembled, turn the handle 12 to disengage the internal threaded tube 9 from the threaded barrel 14, so that the connecting frame 15 can be taken out. At this time, the filter screen 13 and the internal threaded tube 9 can be cleaned. When the connecting frame 15 needs to be installed, first place the connecting frame 15 on the support ring 11, and the support ring 11 supports the connecting frame 15. At this time, screw the internal threaded tube 9 onto the threaded barrel 14 to fix the connecting frame 15 and the filter screen 13.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
