Technical Field
[0001] The utility model relates to the technical field of cell voltage detection devices, and particularly relates to a cell voltage detection device. Background Art
[0002] A cell voltage detection device is a device for detecting the voltage of cells inside a battery. The cell is placed on the surface of an operating table, and the positive and negative electrodes of the cell are contacted by probes so as to detect the voltage of the cell.
[0003] The inventor found during daily use of the cell voltage detection device that when detecting the voltage of cells of different sizes, the probes are usually moved by an electric telescopic rod. Since the probes need to contact the cells to detect the voltage, it will cause the probes to be damaged easily when the probes are moved and directly hit the surface of the cells for a long time, thus causing an impact. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a cell voltage detection device.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A cell voltage detection device includes an operating table. A fixing plate is fixedly connected to the upper top of the operating table. A hydraulic rod is fixedly connected to the upper top of the operating table. One end of the hydraulic rod is fixedly connected to a push rod. A probe is arranged on the side of the push rod. A rectangular groove is opened on the upper top of the operating table. The push rod is slidably connected to the inside of the rectangular groove. A clamping assembly is arranged on the surface of the fixing plate. A buffer device is arranged on the side of the push rod. An adjusting device is arranged on the surface of the push rod. The buffer device includes a circular groove opened on the side of the push rod. A spring rod is arranged inside the circular groove. One end of the spring rod is fixedly connected to a sliding rod. One end of the sliding rod is fixedly connected to a circular plate. The probe is fixedly connected to the side of the circular plate.
[0006] The effects achieved by the above components are as follows: Under the action of the spring rod, when the push rod contacts the cell under the action of the hydraulic rod, a rigid clamping phenomenon will not occur, avoiding the situation that the probe cannot buffer after hitting the surface of the cell. When it is necessary to detect the cell, the cell is placed on the surface of the fixing plate, and the cell is fixed on the surface of the fixing plate by the clamping assembly. The hydraulic rod is started to make the push rod move inside the rectangular groove, and then the probe is pushed against the positive and negative electrodes of the cell on the surface of the fixing plate, and then the voltage of the cell is detected.
[0007] Preferably, a groove is opened on the side of the push rod. A round rod is slidably connected to the inside of the groove. One end of the round rod is fixedly connected to the side of the circular plate.
[0008] The effects achieved by the above components are as follows: Under the action of the round rod, the sliding rod will not shake during buffering, so that the sliding rod can move smoothly.
[0009] Preferably, a rubber ring is fixedly connected to the side surface of the round plate, and the rubber ring is arranged on the side of the round plate close to the push rod.
[0010] The effects achieved by the above components are as follows: Under the action of the rubber ring, the round plate will not directly impact the surface of the push rod, thus avoiding the phenomenon that one end of the sliding rod directly impacts the inner wall of the round groove during buffering and cannot be buffered.
[0011] Preferably, a baffle is fixedly connected to the inner wall of the round groove, and a baffle is fixedly connected to one end of the sliding rod.
[0012] The effects achieved by the above components are as follows: Under the action of the baffle, the sliding rod will not extend out of the round groove, thus avoiding the separation of the sliding rod from the round groove. When detecting the voltage of the battery cell, the hydraulic rod is started to push the push rod to move towards the side of the fixed plate, so that the probe contacts the positive and negative electrodes of the battery cell. When the probe contacts the positive and negative electrodes of the battery cell, under the action of the spring rod, the sliding rod contracts towards the inside of the round groove, so that the probe will not directly contact the battery cell, avoiding the phenomenon of damage after directly impacting the surface of the positive and negative electrodes of the battery cell. Under the action of the round rod, the sliding rod will not shake during buffering, so that the sliding rod can move smoothly. During the buffering process, under the action of the rubber ring, the round plate will not directly impact the surface of the push rod, thus avoiding the phenomenon that one end of the sliding rod directly impacts the inner wall of the round groove during buffering and cannot be buffered. Under the action of the baffle, the sliding rod will not extend out of the round groove, thus avoiding the separation of the sliding rod from the round groove, thereby achieving the buffering effect.
[0013] Preferably, the adjusting device includes a long groove opened in the push rod, a telescopic rod is slidably connected inside the long groove, a first spring is fixedly connected inside the long groove, and both ends of the first spring are fixedly connected to the bottom of the telescopic rod and the inner wall of the long groove respectively.
[0014] The effects achieved by the above components are as follows: Under the action of the first spring, the telescopic rod can slide inside the long groove, thus achieving the phenomenon of adjusting the height of the probe.
[0015] Preferably, a clamping rod is inserted into the side surface of the push rod, a clamping groove is opened on the side surface of the telescopic rod, and the clamping rod is inserted into the inside of the clamping groove.
[0016] The effects achieved by the above components are as follows: Under the action of the clamping rod, after the telescopic rod extends and retracts to a suitable position, it can be fixed by inserting the clamping rod into the inside of the clamping groove.
[0017] Preferably, a second spring is sleeved on the side surface of the clamping rod, and two ends of the second spring are respectively fixedly connected to the side surface of the push rod and an end of the clamping rod away from the push rod.
[0018] The effect achieved by the above components is that under the action of the second spring, the clamping rod is inserted into the interior of the clamping slot in a self-locking manner, thereby achieving a fixing effect.
[0019] Preferably, a clamping plate is fixedly connected to the inner wall of the long slot, and a clamping plate is fixedly connected to the bottom of the telescopic rod.
[0020] The effects achieved by the above components are: under the action of the card plate, the telescopic rod will not disengage from the inside of the long slot. When it is necessary to adjust the height of the push rod, the card rod is pulled outward to separate the card rod from the card slot, and then under the action of the first spring, the telescopic rod can slide inside the long slot. Under the action of the card plate, the telescopic rod will not disengage from the inside of the long slot, thereby achieving the phenomenon of adjusting the height of the probe. After adjusting to the appropriate height, under the action of the second spring, the card rod is self-locking and inserted into the inside of the card slot, thereby achieving the effect of fixing, thereby achieving the effect of adjustment.
[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

A buffer device 2 is arranged on the side surface of the push rod 5. An adjusting device 3 is arranged on the surface of the push rod 5. When it is necessary to detect the cell, the cell is placed on the surface of the fixed plate 6, and the cell is fixed on the surface of the fixed plate 6 through the clamping component 7. The hydraulic rod 4 is started to make the push rod 5 move inside the rectangular groove 8, so as to push the probe to stick to the positive and negative poles of the cell on the surface of the fixed plate 6, and then the voltage of the cell is detected.

One end of the spring rod 22 is fixedly connected to a slide rod 23. One end of the slide rod 23 is fixedly connected to a circular plate.

When it is necessary to detect the battery cell, the battery cell is placed on the surface of the fixing plate 6, and the battery cell is fixed on the surface of the fixing plate 6 through the clamping assembly 7. The hydraulic rod 4 is started to make the push rod 5 move inside the rectangular groove 8, and then the probe is pushed against the positive and negative electrodes of the battery cell on the surface of the fixing plate 6, and then the voltage of the battery cell is detected. A groove 26 is formed on the side surface of the push rod 5. A round rod 25 is slidably connected inside the groove 26. One end of the round rod 25 is fixedly connected to the side surface of the circular plate. Under the action of the round rod 25, the slide rod 23 will not shake during buffering, and then the slide rod 23 can move smoothly. A rubber ring 27 is fixedly connected to the side surface of the circular plate. The rubber ring 27 is arranged on the side of the circular plate close to the push rod 5. Under the action of the rubber ring 27, the circular plate will not directly impact the surface of the push rod 5, and then the situation where one end of the slide rod 23 directly impacts the inner wall of the circular groove 21 and cannot buffer during buffering is avoided. A baffle 24 is fixedly connected to the inner wall of the circular groove 21. One end of the slide rod 23 is fixedly connected to the baffle 24.

When detecting the voltage of the battery cell, the hydraulic rod 4 is started to push the push rod 5 to move towards the side surface of the fixing plate 6, and then the probe is brought into contact with the positive and negative electrodes of the battery cell.

A clamping rod 34 is inserted into the side of the push rod 5, and a clamping slot 36 is provided on the side of the telescopic rod.
