The utility model can maintain the firmness of the clamped battery by respectively arranging the battery plate and the battery cover on the two connecting rods and using the magnetic attraction of the electromagnet and the adsorption iron plate. The utility model has a reasonable structure and strong practicality.

[0004] Some problems were found when using the above-mentioned existing battery parallel clamp for the charge and discharge test machine. First, the positive and negative terminal positions of batteries of different models are different, and the positions of the negative and positive contacts cannot be changed, so the applicability is low and it can only clamp batteries of fixed models. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a battery parallel clamp, including a base 1, a transparent vertical plate 3 is fixedly installed on one side of the base 1, a limiting slide groove 301 is provided in the transparent vertical plate 3, a first conductive column 4 is slidably installed in the limiting slide groove 301, a second conductive column 401 is slidably installed in the limiting slide groove 301 and in front of the first conductive column 4, an adjustment frame 302 is fixedly installed on the other side of the transparent vertical plate 3, two adjusting screws 6 are rotatably installed in the adjusting frame 302, a threaded ring 501 is threadedly installed on the adjusting screw 6, a conductive copper column 5 is fixedly installed on one side of the threaded ring 501, one of the conductive copper columns 5 is fixedly connected to one side of the first conductive column 4 through the conductive column, and the other conductive copper column 5 is fixedly connected to the lower end of the second conductive column 401 through the conductive column.

[0022] In this embodiment, the threaded collar 501 can be driven to move by rotating the adjustment screw 6, and the movement of the threaded collar 501 can drive the conductive copper column 5 to move. The two conductive copper columns 5 are respectively fixed to the first conductive column 4 and the second conductive column 401 through the conductive columns, so that adjusting one conductive copper column 5 alone can drive the first conductive column 4 or the second conductive column 401 to move, thereby adjusting the positions of the first conductive column 4 and the second conductive column 401, so that the first conductive column 4 and the second conductive column 401 are aligned with the positive and negative poles of the battery, thereby connecting the positive and negative poles of multiple batteries in parallel, and being able to adapt to batteries of different specifications and different positive and negative pole positions. The two conductive copper columns 5 are staggered up and down to avoid interference.

[0023] Among them, in order to achieve the purpose of clamping the battery, the present device is implemented by the following technical scheme: a stop block 101 is fixedly installed on the base 1 and close to the edge of the other side, a telescopic column 102 is fixedly installed on one side of the stop block 101, a clamping plate 104 is fixedly connected to the other end of the telescopic column 102, a return spring 103 is sleeved on the telescopic column 102, and a positioning plate 2 is fixedly installed equidistantly on the base 1.

[0024] The clamping plate 104 can be connected by the telescopic column 102 to move the clamping plate 104 left and right. The return spring 103 can provide a certain thrust for the clamping plate 104, so that the clamping plate 104 and the transparent vertical plate 3 cooperate with each other to clamp the battery in the middle position. Figure 2As shown, the positioning plate 2 can be used to position the batteries, and the batteries are attached to the positioning plate 2, so that multiple groups of batteries are clamped on the base 1 at equal intervals.

[0025] Among them, in order to achieve the purpose of stable connection of the battery, the present device is implemented by adopting the following technical solutions: the second conductive column 401 and the opposite surfaces of the first conductive column 4 are fixedly installed with insulating protrusions 403, the first conductive column 4 and the second conductive column 401 are fixedly installed with conductive springs 402 near the upper edge on one side, the conductive copper column 5 is fixedly installed with a wiring terminal 502 at one end, and the adjusting screw 6 is fixedly installed with a knob 601 at one end.

[0026] The insulating boss 403 can prevent the second conductive column 401 from fitting against the first conductive column 4, which would cause a short circuit between the positive and negative electrodes. After the conductive spring 402 contacts the positive and negative electrodes of the battery, it will be deformed by force. When the battery shakes slightly, the conductive spring 402 can reset and still maintain a stable connection with the positive and negative electrodes of the battery. The terminal 502 is used to connect to an external power source, so that electricity is transmitted to the first conductive column 4 and the second conductive column 401 through the conductive copper column 5. The knob 601 can drive the adjusting screw 6 to rotate.

[0027] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, the clamping plate 104 is pulled to move to one side, the battery fitting positioning plate 2 is placed on the base 1, and at the same time, the positive and negative poles are ensured to face the transparent vertical plate 3, and the clamping plate 104 is released. The battery will be clamped under the push of the return spring 103, and the rotating knob 601 drives the adjusting screw 6 to rotate. The rotation of the upper adjusting screw 6 can drive the first conductive column 4 to move, and the rotation of the lower adjusting screw 6 can drive the second conductive column 401 to move. The first conductive column 4 and the second conductive column 401 are adjusted to suitable positions, so that the first conductive column 4 and the second conductive column 401 are respectively against the positive and negative poles of the battery, and the positive and negative poles of the battery can be clamped in parallel.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
