[0001] The application relates to the technical field of testing devices, in particular to a filter assembly pressure burst testing device. BACKGROUND

[0002] The filter assembly is a structure for filtering impurities in liquid or gas, and is mainly applied to an oil pump of an automobile. The filter assembly needs to be tested for pressure burst to detect the maximum pressure resistance under blockage of the filter assembly.

[0003] In the related art, the testing device comprises a water inlet pipeline, a pressure cylinder and a pressure tester. The water inlet pipeline supplies water to the filter assembly. The pressure cylinder is provided with a detection column. The detection column is provided with a connecting pipeline. The pressure cylinder drives the detection column to be inserted into the filter assembly. The pressure tester is arranged on the connecting pipeline and can detect the pressure in the connecting pipeline.

[0004] The water inlet pipeline supplies water to the filter assembly. The pressure cylinder allows the detection column to be stably inserted into the filter assembly, so that the connecting pipeline is filled with water. The pressure tester detects the pressure when the connecting pipeline is damaged.

[0005] After the connecting pipeline is damaged, water will be discharged, and the water will flow to the ground. Therefore, the staff needs to clean up the water, which is troublesome for the staff to use the testing device. CONTENT OF THE INVENTION

[0006] In order to solve the problem that the water flows to the ground after the connecting pipeline is damaged, the application provides a filter assembly pressure burst testing device.

[0007] The filter assembly pressure burst testing device provided by the application adopts the following technical scheme:

[0008] The filter assembly pressure burst testing device comprises a water inlet pipeline, a pressure cylinder and a pressure detector. The water inlet pipeline is used to supply water to the filter assembly. The pressure cylinder is provided with a detection column. The detection column is provided with a connecting pipeline. The connecting pipeline is connected with the pressure detector. The device further comprises a base. The water inlet pipeline, the pressure cylinder and the pressure detector are arranged on the base. The base is provided with a water retaining ring. The connecting pipeline is located in the water retaining ring.

[0009] By arranging the water retaining ring on the base and locating the connecting pipeline in the water retaining ring, when the connecting pipeline is damaged, the water in the connecting pipeline can flow in the water retaining ring. The water retaining ring limits the water, so that the water does not flow outside. This facilitates the staff to wipe the water and reduces the difficulty of the staff to clean up.

[0010] Optionally, the base is provided with a mounting block, the mounting block is provided with a mounting groove for placing the filtering assembly, the mounting block is provided with a through hole communicating with the mounting groove, and the through hole is used for inserting the water inlet pipeline.

[0011] By placing the filtering assembly in the mounting groove, the groove wall of the mounting groove supports the filtering assembly, so that the filtering assembly is not easy to move, and the pressing cylinder can stably press the filtering assembly, thereby avoiding shaking of the filtering assembly during water conveying.

[0012] Optionally, the base is rotatably connected with a limiting plate, the limiting plate is provided with a through hole for passing the connecting pipeline, and the limiting plate is provided with a fixing assembly for limiting rotation of the limiting plate.

[0013] By limiting the rotation of the limiting plate by the fixing assembly and locating the connecting pipeline in the through hole, the limiting plate can limit the movement of the connecting pipeline on the base, thereby avoiding the problem of random flow of water in the connecting pipeline due to random swinging of the connecting pipeline after the connecting pipeline is broken.

[0014] Optionally, the fixing assembly comprises a fixing strip and a fixing block, the fixing strip is slidably connected to the base, the fixing block is arranged on the fixing strip, the limiting plate is provided with a fixing hole for passing the fixing strip, the limiting plate is provided with a receiving hole for passing the fixing block, the limiting plate is provided with a groove for inserting the fixing block, and the receiving hole and the groove are in communication with the fixing hole; when the fixing block is located in the groove, the fixing strip is fixed to the limiting plate.

[0015] By sliding the fixing strip, passing the fixing strip through the fixing hole and the fixing block through the receiving hole, and then sliding the fixing strip to locate the fixing block in the groove, the fixing block can limit the limiting plate, and the limiting plate can be fixed to the base, thereby reducing the swinging of the connecting pipeline due to breakage.

[0016] Optionally, the base is provided with a water outlet, and the water outlet is slidably connected with a water blocking block for blocking the water outlet.

[0017] By arranging the water outlet on the base and blocking the water outlet by the water blocking block, when the water blocking block is slid, the water blocking block does not block the water outlet, so that the water outlet can stably discharge accumulated water, and the worker does not need to wipe the water blocking ring, thereby reducing the operation steps of the worker.

[0018] Optionally, the water blocking block is provided with a connecting strip, and the fixing strip is slidingly connected to the connecting strip; when the fixing block is located in the fixing hole, the water blocking block can be separated from the water outlet; and when the fixing block is located in the groove, the water blocking block blocks the water outlet.

[0019] By adopting the above technical scheme, since the fixing strip is slidingly connected to the connecting strip, the connecting strip can drive the fixing strip to move, when the fixing block is separated from the groove, the water blocking block is moved by the staff, the water blocking block can drive the fixing strip to move through the connecting strip, so that the fixing block can be moved from the groove to the fixing hole, and the unlocking of the limiting plate by the fixing strip is realized.

[0020] Optionally, the fixing strip is provided with a fixing spring, the fixing spring is arranged on the connecting strip, and the fixing spring drives the fixing block to be inserted into the groove.

[0021] By adopting the above technical scheme, the fixing spring is arranged on the fixing strip and the connecting strip, so that the fixing spring can drive the fixing strip to move, and the fixing block is located in the groove, thereby avoiding that the fixing strip slides on the connecting strip to cause the fixing block to be separated from the groove, and further increasing the firmness between the fixing strip and the connecting strip.

[0022] Optionally, the water blocking block is rotatably connected with a stop strip, and the base is provided with a stop groove for inserting the stop strip; when the stop strip is inserted into the stop groove, the water blocking block blocks the water outlet.

[0023] By adopting the above technical scheme, the stop strip is located in the stop groove, the groove wall of the stop groove limits the movement of the stop strip, that is, the base limits the movement of the stop strip, thereby reducing the possibility that the water blocking block is driven by water flow and does not block the water outlet.

[0024] Optionally, the base is provided with a containing groove, the limiting plate is rotatably connected in the containing groove, a containing inclined surface is arranged on the bottom wall of the containing groove, and the distance between the containing inclined surface and the water outlet gradually decreases in the vertically downward direction.

[0025] By adopting the above technical scheme, the distance between the containing inclined surface and the water outlet gradually decreases in the vertically downward direction, so that the water flow can flow along the inclined direction of the containing inclined surface towards the water outlet, the possibility of water accumulation on the base is reduced, the staff does not need to perform water absorption treatment on the base, and the operation steps of the staff are reduced.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] 1. The water retaining ring is arranged on the base through the water retaining ring, and the connecting pipeline is located in the water retaining ring. When the connecting pipeline breaks, the water in the connecting pipeline can spread in the water retaining ring, so that the water retaining ring limits the water, avoids the water flowing out, and facilitates the staff to wipe the water, reduces the difficulty of the staff to clean up.

[0028] 2. The fixing assembly limits the rotation of the limiting plate, and the connecting pipeline is located in the through hole, so that the limiting plate can limit the movement of the connecting pipeline on the base, avoiding the problem that the water in the connecting pipeline flows randomly after the connecting pipeline breaks and swings randomly.
