[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The sensor impact force test device provides two technical solutions:

[0024] like Figure 1 and 2 The first embodiment is shown: comprising a test tube 1 and a T-shaped end cap 2, the front and back of the test tube 1 are both provided with a highly applicable mounting mechanism for mounting a sensor, and the highly applicable mounting mechanism comprises:

[0025] The mounting assembly 3 comprises a groove 31 and a sealing plate 32 which are provided on the front side of the test tube 1. A test hole 33 is provided on the back side of the inner wall of the groove 31. A rubber sleeve 34 is placed inside the test hole 33, and the sensor to be tested is installed inside the rubber sleeve 34. Long slide grooves 35 are provided on the left and right sides of the inner wall of the groove 31. Long blocks 36 are fixedly connected on the left and right sides of the sealing plate 32. The sealing plate 32 is inserted into the groove 31 through the cooperation of the long slide grooves 35 and the long blocks 36. The shape of the inner surface of the rubber sleeve 34 is specially made according to the size and shape of the sensor to be tested, and the shape of the outer surface is consistent with the shape of the test hole 33. Two left and right magnets 37 are inlaid on the top of the sealing plate 32, and iron blocks corresponding to the positions of the two magnets 37 are inlaid on the bottom of the inner wall of the groove 31.

[0026] When the sensor is installed in the test device, the outside of the sensor is wrapped by the rubber sleeve 34. The inner surface shape of the rubber sleeve 34 is specially made to adapt to the sensor. There is no need for a special test hole 33. When testing different sensors, it is only necessary to replace the special rubber sleeve 34, which improves the applicability of the device when used.

[0027] like Figure 2 and 3The second embodiment is shown, and the main difference from the first embodiment is that a clamping assembly 4 is arranged in a sealing plate 32, and is used to clamp the sensor and rubber sleeve 34 installed in the test hole 33. The clamping assembly 4 includes a U-shaped groove 41 opened in the sealing plate 32, and two left and right arc grooves 42 are opened on the back of the sealing plate 32, and the two arc grooves 42 are connected to the U-shaped groove 41. An intermediate rod 43 is fixedly connected between the left and right sides of the inner wall of the U-shaped groove 41, and the surface of the intermediate rod 43 is slidably connected with left and right semicircular blocks 44. The middle parts of the opposite sides of the two intermediate rods 43 are provided with wire holes, and the surfaces of the intermediate rod 43 located on the opposite sides of the two semicircular blocks 44 are sleeved with a reset spring 45, and the front of the right semicircular block 44 is fixedly connected with a push plate 46.

[0028] After the sensor is installed in the test hole 33 through the rubber sleeve 34, the left and right semicircular blocks 44 of the clamping assembly 4 are blocked in front of the rubber sleeve 34 and the sensor, thereby ensuring the stability of the sensor and the rubber sleeve 34 during the impact force test.

[0029] When in use, a special rubber sleeve 34 is made according to the shape of the sensor to be tested, so that the inner surface of the rubber sleeve 34 is consistent with the size and shape of the sensor, the sensor is inserted into the inside of the rubber sleeve 34, and the rubber sleeve 34 with the sensor is placed in the test hole 33, and the sealing plate 32 is inserted from the bottom of the groove 31. During insertion, the long slide groove 35 and the long block 36 are aligned. After insertion, the position of the sealing plate 32 is fixed by the adsorption effect of the magnet 37. In addition, while inserting the sealing plate 32, the two semicircular blocks 44 are moved away from each other by the push plate 46. After the sealing plate 32 is inserted into place, the push plate 46 is released, and the two semicircular blocks 44 are reset under the action of the reset spring 45, and the wires on the sensor are led out from the wire hole between the two semicircular blocks 44.
