[0035] A retaining ring 26 is fixedly sleeved on the upper end of the barrel body 21 , a first threaded portion 27 is fixedly connected to the top of the barrel body 21 , and a second nut 28 is threadedly sleeved on the first threaded portion 27 .

[0036] Specifically, the barrel 21 is detachably connected to the outer sleeve 23 through a first nut 22 provided at the bottom. The upper part of the inner sleeve 24 is clamped to the upper end of the outer sleeve 23 and is tightened and fixed by the first nut 22. During operation, the probe 25 is used to perform contact testing with the battery test point. When the applied pressure is within a normal range, the probe 25 does not move. When improper operation or other unexpected circumstances cause the probe 25 to be subjected to excessive force, the probe 25 disengages from the clamping part with the inner sleeve 24 and moves upward, and the bottom of the probe 25 is retracted into the inner sleeve 24, which can protect the probe 25 and avoid damage, and also avoid damage to the battery test point.

[0037] The outer sleeve 23 is provided with a second threaded portion 231 on the upper part, and a clamping groove 232 is symmetrically opened on the second threaded portion 231. A first through hole 233 is opened horizontally through the middle part of the outer sleeve 23. Blocks 242 are provided on both sides of the top of the inner sleeve 24. A second through hole 241 is opened horizontally through the position below the block 242 on the inner sleeve 24. The second through hole 241 has the same size and position as the first through hole 233. Positioning balls 243 are rolled and connected on both sides of the inner sleeve 24. The first nut 22 is threadedly sleeved on the second threaded portion 23 1, the clamping block 242 is clamped in the clamping groove 232, the top of the first nut 22 is fixedly connected to the bottom of the barrel 21, and the bottom is press-fitted on the clamping block 242. The probe 25 is arranged through the barrel 21 and the inner sleeve 24. Positioning grooves 251 corresponding to the positioning balls 243 are opened on both sides of the probe 25. The positioning balls 243 are clamped in the positioning grooves 251. The two sides of the middle of the probe 25 are fixedly connected with the shifting rods 252. The shifting rods 252 are arranged through the second through hole 241 and the first through hole 233. The spring 253 is fixedly sleeved on the upper part of the probe 25.

[0038] Specifically, the bottom of the inner sleeve 24 is sleeved in the outer sleeve 23, the clamping block 242 is clamped in the clamping groove 232, the first nut 22 is threadedly connected to the second threaded portion 231 and tightened, the first nut 22 is pressed tightly on the clamping block 242, so that the inner sleeve 24 is firmly fixed in the outer sleeve 23, the probe 25 is inserted into the inner sleeve 24, and the positioning ball 243 is clamped in the positioning groove 251. The positioning ball 243 can be made of a material with a small range of elastic deformation and a large friction force, such as rubber material. Under normal pressure, the positioning ball 243 and the positioning groove The engagement of 251 fixes the probe 25. When the force is too great, the positioning groove 251 disengages from the positioning ball 243, and the probe 25 moves upward, compressing the spring 253 and driving the lever 252 to move upward at the same time. The end of the lever 252 away from the probe 25 extends to the outside of the second through hole 241 and the first through hole 233, so that the inspector can grasp the position of the probe 25. That is, when the lever 252 moves upward, the probe 25 is in an abnormal position, and the inspector can move the lever 252 downward to re-engage the positioning groove 251 with the positioning ball 243.

[0039] The above technical solution can, on the one hand, avoid damage to the probe 25 and the battery test point, and on the other hand, enable the tester to understand the working status of the probe 25 and make timely adjustments, which is simple and quick.

[0040] like Figure 1-Figure 3 and Figure 5As shown, the probe test mounting frame with probes according to the embodiment of the present application includes a support plate 14 and a storage box 12, the probe is movably arranged on the support plate 14, a movable groove 141 is provided on the support plate 14, both ends of the support plate 14 are fixedly connected to the storage box 12, an installation groove 121 is provided on the storage box 12, a cleaning brush 122 is inserted in the installation groove 121, a level 13 is fixedly installed in the middle of the support plate 14, two storage boxes 12 are grouped together, and two groups are provided. The two groups of storage boxes 12 are movably connected by screws 15 and guide rods 16, and the bottom of the storage box 12 is fixedly connected to an adjustable support rod 11, wherein the bottom of one group of adjustable support rods 11 is fixedly connected to the two guide rails 1, and the bottom of the other group of adjustable support rods 11 is slidably connected to the guide rail 1.

Figure 1 One end of the screw 15 is rotatably installed on the upper left storage box 12, and a screw sleeve 123 is fixedly connected to the lower left storage box 12. The screw sleeve 123 is threadedly sleeved on the screw 15, and one end of the guide rod 16 is fixedly installed on the upper right storage box 12, and the other end is slidably sleeved on the lower right storage box 12. The distance between the upper and lower groups of storage boxes 12 is adjusted by the screw 15. Rotating the screw 15 makes the lower group of storage boxes 12 approach or move away from the upper group of storage boxes 12, and the adjustable support rod 11 corresponding to the bottom of the storage box 12 moves accordingly, which can be adjusted accordingly according to the position of the battery test point. The height is adjusted and fixed by the adjustable support rod 11. During the adjustment process, the level of the support plate 14 can be grasped by observing the level instrument 13 to ensure that the probe moves horizontally in the movable groove 141.

[0042] Specifically, the storage box 12 is used to store probes. After each test is completed, the retaining ring 26 is clamped on the upper end of the storage box 12, and the probe is pushed into the storage box 12 for storage. By providing a cleaning brush 122 on the storage box 12, dust or impurities on the surface of the probe can be removed when the probe is sent into the storage box 12, thereby ensuring the cleanliness of the probe.

[0043] In summary, the working principle of a probe and a probe test mounting bracket in an embodiment of the present invention is: when in use, the probe is adjusted according to the position and height of the battery test point, the distance between the two groups of probes is adjusted by the screw 15, the probe height is adjusted by the adjustable support rod 11, and the detection position of the probe is adjusted and fixed by the second nut 28, and the probe 25 is brought into contact with the battery test point, and the test results are displayed and recorded by the corresponding test equipment. During use, when the probe is subjected to excessive force due to improper operation or an unexpected situation, the positioning groove 251 disengages from the positioning ball 243, and the probe 25 drives the lever 252 to move upward, and the bottom of the probe 25 is retracted into the inner sleeve 24, thereby avoiding damage to the probe 25 and the battery test point.
