Description

Technical Field

[0001] This utility model relates to the field of water pump control technology, and in particular to a water pump pressure switch housing. Background Technology

[0002] A water pump pressure switch is a fully electronic and intelligent water pump control device. It starts and stops the water pump based on data such as the detected water source status, water consumption in the pipeline, and changes in pipeline pressure. The lower limit pressure of the water pump pressure switch is usually set at the factory. However, in actual use, the lower limit pressure needs to be changed according to the working environment. This requires disassembling the water pump pressure switch, rotating the adjusting bolt or spring nut to change the lower limit pressure, and then reinstalling the switch. However, the disassembly and installation of existing water pump pressure switches is inconvenient, requiring the use of various disassembly tools. The lower limit pressure needs to be readjusted every time a new working environment is encountered, which is cumbersome and affects work efficiency.

[0003] Therefore, it is necessary to invent a housing for a water pump pressure switch to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a housing for a water pump pressure switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water pump pressure switch housing, comprising a first housing and a second housing. A mounting base is connected to the bottom of the first housing. The second housing consists of a top plate, two first side plates, and two second side plates. A vent is provided on the first side plate, and a vent filter is connected to the vent. Limiting components are connected to both sides of the first housing. Each limiting component includes a first mounting block connected to the first housing. A second mounting block is connected to one side of the first mounting block. Cavities are formed in the inner walls of both the first and second mounting blocks, and these cavities are connected. A sliding rod is provided within the cavity of the second mounting block. A fixing plate is connected to the inner wall of the cavity of the first mounting block. A spring is connected between the fixing plate and the inner wall of the second mounting block. The sliding rod passes through the fixing plate and the second mounting block and is connected to a rotating rod. The sliding rod passes through the first mounting block and is connected to the limiting block. Horizontal limiting openings are formed on one side of the first mounting block and both sides of the first housing. Vertical limiting openings are formed on one side of each of the two second side plates.

[0006] Preferably, the first housing and the first side plate are fitted together, and a gap is left between the first housing and the second side plate, the width of which is the same as the thickness of the limiting block.

[0007] Preferably, a pad is connected to one side of the limiting block, and the pad is made of rubber.

[0008] Preferably, a plurality of limiting grooves corresponding to the first side plate and the second side plate are formed at the bottom of the inner wall of the first housing.

[0009] Preferably, the first housing has slots on both sides corresponding to the air-permeable filter.

[0010] The technical effects and advantages of this utility model are as follows: By using a first housing, a second housing, a second side plate, a sliding rod, a spring, a rotating rod, and a limiting block in conjunction, when installing the water pump pressure switch, pushing the rotating rod causes the limiting block to move via the sliding rod. The limiting block passes through the lateral limiting opening between the first mounting block and the first housing and enters the gap between the first and second housings. Rotating the rotating rod causes the limiting block to rotate 90°. Pushing the rotating rod again causes the limiting block to pass through the vertical limiting opening of the second housing via the sliding rod. Rotating the rotating rod again without applying force causes the limiting block to limit the second housing due to the spring force, thus realizing the installation of the water pump pressure switch. To disassemble the water pump pressure switch, simply reverse the above steps. The water pump pressure switch can be disassembled without tools, facilitating the adjustment of the lower limit pressure according to the working environment and improving work efficiency.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-7 The water pump pressure switch housing shown includes a first housing 1 and a second housing 2. A mounting base 3 is connected to the bottom of the first housing 1. The second housing 2 consists of a top plate 4, two first side plates 5, and two second side plates 6. A vent is provided on each of the first side plates 5, and a vent filter 7 is connected to the vent. Limiting components 8 are connected to both sides of the first housing 1. Each limiting component 8 includes a first mounting block 9 connected to the first housing 1, and a second mounting block 10 connected to one side of the first mounting block 9. Both the first mounting block 9 and the second mounting block 10 have cavities in their inner walls. The cavities are connected. A sliding rod 11 is provided in the cavity of the second mounting block 10. A fixing plate 12 is connected to the inner wall of the cavity of the first mounting block 9. A spring 13 is connected between the fixing plate 12 and the inner wall of the second mounting block 10. The sliding rod 11 passes through the fixing plate 12 and the second mounting block 10 and is connected to a rotating rod 14. The sliding rod 11 passes through the first mounting block 9 and is connected to a limiting block 15. A horizontal limiting port 16 is provided on one side of the first mounting block 9 and on both sides of the first housing 1. A vertical limiting port 17 is provided on one side of each of the two second side plates 6. The limiting block 15 can simultaneously fix the first housing 1 and the second housing 2.

[0021] The first housing 1 and the first side plate 5 are attached to each other, and there is a gap between the first housing 1 and the second side plate 6. The width of the gap is the same as the thickness of the limiting block 15, which facilitates the multiple rotations of the limiting block 15.

[0022] A pad 18 is connected to one side of the limiting block 15. The pad 18 is made of rubber to increase friction and make the fixation more stable.

[0023] Multiple limiting grooves corresponding to the first side plate 5 and the second side plate 6 are opened at the bottom of the inner wall of the first housing 1 to initially position the second housing 2.

[0024] The first housing 1 has slots on both sides corresponding to the breathable filter 7, so that the breathable filter 7 can be used normally, and at the same time, it is easy to remove the second housing 2 from the first housing.

[0025] The working principle of this utility model is as follows: When installing the water pump pressure switch, push the rotating rod 14, which drives the limiting block 15 to move through the sliding rod 11. The limiting block 15 passes through the horizontal limiting port 16 of the first mounting block 9 and the first housing 1 and enters the gap between the first housing 1 and the second housing 2. Rotate the rotating rod 14, which drives the limiting block 15 to rotate 90°. Push the rotating rod 14 again, which drives the limiting block 15 to pass through the vertical limiting port 17 of the second housing 2 through the sliding rod 11. Rotate the rotating rod 14 again, and no longer apply force to the rotating rod 14. Due to the elastic force of the spring 13, the limiting block 15 will limit the second housing 2, thus realizing the installation of the water pump pressure switch. If you want to disassemble the water pump pressure switch, simply reverse the above steps.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
