Description

Technical Field

[0001] This utility model relates to the field of filter screen technology, specifically a water pump inlet filter screen. Background Technology

[0002] The water pump inlet filter screen is used to filter out impurities in the water, prevent them from entering the pump, and ensure that the impeller is not entangled in impurities.

[0003] Currently, traditional water pump inlet filter covers require additional fasteners such as cable ties to connect and secure them to the water pump. This makes assembly and disassembly cumbersome and cannot guarantee a proper fit between the top of the water pump and the top of the filter cover. This can easily cause debris to flow into the filter cover from the top of the connection point, resulting in ineffective filtration. Therefore, we propose a new water pump inlet filter cover. Utility Model Content

[0004] The purpose of this invention is to provide a water pump inlet filter screen 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 inlet filter screen cover, comprising:

[0006] The filter screen body is used to protect the water inlet of the water pump;

[0007] The clamping ring is used to seal the connection between the filter screen body and the water pump;

[0008] The locking device is used to fix the water pump by pressing the ring, so that the filter screen body is directly connected to the water pump.

[0009] Preferably, the locking device includes a mounting post and a limiting post, both welded to the top edge of the filter screen body. A circular hole is formed in the center of each post. A U-shaped handle is provided on each post, passing through the circular hole in the center. A limiting slot is formed on the side of the limiting post closest to the mounting post. A washer is rotatably mounted on the side of the limiting post furthest from the mounting post. A connecting spring is fixed to the side of the washer furthest from the limiting post. The end of the connecting spring furthest from the washer is fixed to the U-shaped handle. An L-shaped pressure rod is fixed to the end of the U-shaped handle. First, the clamping ring is placed around the outside of the water pump, then the water pump... After inserting the filter screen body, pull the U-shaped handle to lift it up, causing the L-shaped pressure rod to abut against the top of the clamping ring. At this time, the L-shaped pressure rod moves to the position of the limiting groove, and the L-shaped pressure rod no longer abuts against the limiting post. Under the action of the connecting spring, the U-shaped handle moves a certain distance closer to the limiting post. The L-shaped pressure rod inserts into the limiting groove, restricting the U-shaped handle so that it cannot rotate, thus restricting the water pump. The overall operation is convenient. Furthermore, the clamping ring fills the space between the filter screen body and the water pump, preventing debris from entering from the top of the filter screen body. The L-shaped pressure rod abuts against the clamping ring, preventing direct contact between the L-shaped pressure rod and the water pump, which could cause scratches on the water pump surface.

[0010] Preferably, the locking device is provided in two sets, and both sets of the locking device are arranged in a circular array with the center point of the filter screen body as the center. The water pump can be fixed more securely by the two sets of locking devices.

[0011] Compared with the prior art, the present invention provides a water pump inlet filter screen cover, which has the following beneficial effects:

[0012] 1. The water pump inlet filter screen cover, through the setting of the locking device and the clamping ring, after the water pump is placed into the filter screen cover body, pull the U-shaped handle to lift it up, so that the L-shaped pressure rod abuts against the top of the clamping ring. At this time, the L-shaped pressure rod moves to the position of the limiting groove, and the L-shaped pressure rod no longer abuts against the limiting post. Under the action of the connecting spring, the U-shaped handle moves a certain distance towards the side of the limiting post. The L-shaped pressure rod inserts into the limiting groove, restricting the U-shaped handle so that the U-shaped handle cannot rotate, thus completing the restriction of the water pump. The overall operation is convenient.

[0013] 2. The water pump inlet filter screen is filled between the filter screen body and the water pump by a pressing ring to prevent debris from entering from the top of the filter screen body. The L-shaped pressure rod abuts against the pressing ring to prevent the L-shaped pressure rod from directly contacting the water pump and causing scratches on the water pump surface.

[0018] like Figures 1-3 As shown, this utility model provides a technical solution: a water pump inlet filter screen cover, including a filter screen cover body 1 and a pressing ring 2. A locking device 3 is provided on the top edge of the filter screen cover body 1. Two sets of locking devices 3 are provided, and both sets of locking devices 3 are arranged in a circular array with the center point of the filter screen cover body 1 as the center. The water pump can be more securely fixed by the two sets of locking devices 3.

[0019] The locking device 3 includes a mounting post 31 and a limiting post 32. Both the mounting post 31 and the limiting post 32 are welded to the top edge of the filter screen body 1. A circular hole is formed in the center of each mounting post 31 and the limiting post 32. A U-shaped handle 33 is provided on the mounting post 31 and the limiting post 32, passing through the circular hole in the center of each. A limiting slot 34 is formed on the side of the limiting post 32 closest to the mounting post 31. A washer 35 is rotatably mounted on the side of the limiting post 32 away from the mounting post 31. A connecting spring 36 is fixed to the side of the washer 35 away from the limiting post 32. The end of the connecting spring 36 away from the washer 35 is fixed to the U-shaped handle 33. An L-shaped pressure rod 37 is fixed to the end of the U-shaped handle 33. First, the clamping ring 2 is placed around the outside of the water pump, and then the water pump is placed... After the filter screen body 1 is inside, pull the U-shaped handle 33 to lift it up, so that the L-shaped pressure rod 37 abuts against the top of the clamping ring 2. At this time, the L-shaped pressure rod 37 moves to the position of the limiting slot 34. The L-shaped pressure rod 37 no longer abuts against the limiting post 32. Under the action of the connecting spring 36, the U-shaped handle 33 moves a certain distance towards the side closer to the limiting post 32. The L-shaped pressure rod 37 is inserted into the limiting slot 34, which restricts the U-shaped handle 33, so that the U-shaped handle 33 cannot rotate, thus restricting the water pump. The overall operation is convenient. The clamping ring 2 fills the space between the filter screen body 1 and the water pump, preventing debris from entering from the top of the filter screen body 1. The L-shaped pressure rod 37 abuts against the clamping ring 2, preventing the L-shaped pressure rod 37 from directly contacting the water pump and causing scratches on the surface of the water pump.

[0020] In this utility model, during use, the clamping ring 2 is first placed on the outside of the water pump. After the water pump is placed inside the filter screen body 1, the U-shaped handle 33 is pulled up, causing the L-shaped pressure rod 37 to abut against the top of the clamping ring 2. At this time, the L-shaped pressure rod 37 moves to the position of the limiting groove 34, and the L-shaped pressure rod 37 no longer abuts against the limiting post 32. Under the action of the connecting spring 36, the U-shaped handle 33 moves a certain distance towards the side closer to the limiting post 32, and the L-shaped pressure rod 37 is inserted into the limiting groove 34, restricting the U-shaped handle 33 so that the U-shaped handle 33 cannot rotate, thus completing the restriction of the water pump. The overall operation is convenient, and the water pump can then be put into the water for operation.

[0021] When removal is required, simply pull the U-shaped handle 33 to move it closer to the mounting post 31 so that the L-shaped pressure rod 37 is no longer stuck in the limiting groove 34. Then, rotate the U-shaped handle 33 so that the L-shaped pressure rod 37 no longer applies pressure to the clamping ring 2. At this point, the water pump and the clamping ring 2 can be removed from the filter screen body 1.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
