Description

TECHNICAL FIELD

[0001] The utility model relates to steel processing equipment field, concretely relates to a hydraulic pump oil inlet filtering structure. BACKGROUND

[0002] In the operation process of the hydraulic pump, the filter screen is the key component to guarantee the cleanliness of the hydraulic oil. The traditional hydraulic pump filter screen has obvious defects, and its installation structure design lacks convenience consideration. Common installation methods such as fastening bolt connection or interference fit make it very inconvenient to disassemble and clean the filter screen when maintenance is needed. Maintenance personnel often need to spend a lot of time to disassemble the surrounding auxiliary components to access the filter screen, and the disassembly process may be further increased in difficulty due to limited operation space and restricted tool use, and the filter screen is prone to falling off from the cleaning equipment or placement platform during cleaning due to the lack of effective fixing auxiliary devices. Once it falls off, it may cause damage to the filter screen, affect its filtering accuracy and reuse effect, and also pollute the surrounding environment, increasing the cleaning workload. This not only affects the maintenance efficiency of the hydraulic pump, but also adversely affects the stable operation and service life of the entire hydraulic system, which needs to be improved.

[0006] A through hole is provided in the first connecting block, and the through hole is used for placing the telescopic rod. The through hole is concentrically arranged with the circular hole, and the telescopic rod is symmetrically arranged at both ends of the through hole.

[0007] The driving assembly includes a connecting plate connected to one end of the telescopic rod. The connecting plate facilitates the movement of the telescopic rod. A limit groove is provided above the through hole. The limit groove is used to limit the connecting plate so that when the connecting plate drives the telescopic rod to move, the connecting rod is prevented from running away and the connecting plate moves better. The connecting plate is slidably set in the limit groove, and a reset assembly is provided between the symmetrically arranged connecting plates.

[0008] The reset component is a reset spring. When the connecting plate moves toward the middle, the reset spring is squeezed.

[0010] The beneficial effects of the above technical solution of the utility model are as follows:

[0011] 1. When the filter needs to be cleaned, just leak out the oil inlet, pull the filter near the second groove to separate the magnets at the bottom of the second groove and the bottom of the second connecting block, and then you can clean the flip filter.

[0012] 2. When the filter needs to be disassembled, press the symmetrically arranged connecting plates at the same time, pull the telescopic rod away from the round hole by moving the connecting plates toward the middle, so that the first connecting block loses the limit of the telescopic rod, and the reversible filter is disassembled.

[0013] 3. When the reversible filter needs to be installed, when placing the first connecting block into the first groove, the same operation is performed to move the connecting plate closer to the middle to squeeze the reset spring. After the first connecting block is placed in the first groove, the connecting plate is released to reset the reset spring and release the compressed elastic potential energy to push the adjacent connecting plate. By pushing the connecting plate, the connecting plate drives the telescopic rod to move toward one side of the circular hole, pushing the telescopic rod into the circular hole, limiting the first connecting block to prevent it from falling, and at the same time making the second connecting block adsorbed with the magnet in the second groove to prevent the reversible filter from flipping during use, causing the filter to lose its function.
