Detailed Embodiment

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0028] Such as Figures 1 - 3As shown in the figure, a lithium battery charge and discharge detection device provided by an embodiment of the present utility model includes a support base 1. A fixing block 2 is connected to the surface of the support base 1, and a storage card slot 12 is provided on the surface of the fixing block 2. An opening 5 is provided on the surface of the fixing block 2, and the opening 5 communicates with the storage card slot 12. The opening 5 is used for arranging detection instruments;

[0029] Positioning springs 14 are installed on both sides inside the storage card slot 12. The number of positioning springs 14 on each side in the storage card slot 12 is preferably 4, and the 4 positioning springs 14 are distributed at the four corners of the inner wall of one side of the storage card slot 12. One end of the positioning spring 14 is connected to a battery clamping plate 15. The number of battery clamping plates 15 is two, and the two battery clamping plates 15 are arranged in parallel inside the storage card slot 12.

[0030] In an embodiment of the present utility model, when it is necessary to perform charge and discharge detection on a lithium battery, the staff can hold the lithium battery by hand and place it inside the storage card slot 12. During the process of placing it into the storage card slot 12, both sides of the lithium battery will abut against the surfaces of the two battery clamping plates 15, causing the battery clamping plates 15 to move through the positioning springs 14. At this time, the positioning springs 14 are in a compressed state, and the compressed positioning springs 14 will apply a squeezing force to the battery clamping plates 15 and the lithium battery located between the two battery clamping plates 15, so that the lithium battery can be stably placed inside the storage card slot 12 for charge and discharge detection.

[0031] Through the above technical solution, when performing charge and discharge detection on a lithium battery, the lithium battery can be conveniently and quickly limited in the charge and discharge detection area, avoiding the problem that the lithium battery accidentally shifts in position during the detection process, which affects the detection effect. Moreover, the limiting structure is simple in structure and low in cost, thereby improving the practicability of the lithium battery charge and discharge detection device.

[0032] Preferably, an installation block 13 is provided inside the storage card slot 12, and the positioning spring 14 is installed on the surface of the installation block 13, so that the positioning spring 14 can be more firmly installed on the inner wall of the storage card slot 12, avoiding the positioning spring 14 falling off the inner wall of the storage card slot 12 after long-term use.

[0033] Preferably, an anti-slip strip 3 is provided on the side of the storage card slot 12 far away from the opening 5. After the lithium battery is placed into the storage card slot 12, the back surface of the lithium battery will be in close contact with the anti-slip strip 3. Furthermore, through the frictional force of fitting between the lithium battery and the anti-slip strip 3, the situation of accidental position deviation of the lithium battery can be further avoided.

[0034] Such as Figure 1 and Figure 4As shown, in an embodiment of the present utility model, a sliding plate 9 is slidably connected to the surface of the support base 1, and a limiting strip 6 is connected to the side surface of the sliding plate 9. A limiting component is jointly arranged on the outer sides of the support base 1 and the sliding plate 9, and the limiting component is used to limit the position of the sliding plate 9. Preferably, the number of the limiting strips 6 is two, and they are respectively arranged on both sides of the surface of the sliding plate 9 close to the fixed block 2;

[0035] A guiding chute 7 is formed on the surface of the support base 1, and a guiding slider 16 is arranged on the surface of the sliding plate 9. The guiding slider 16 is slidably connected inside the guiding chute 7. The sliding plate 9 is slidably connected to the surface of the support base 1 through the cooperation of the guiding slider 16 and the guiding chute 7. The number of the guiding chutes 7 is two, the number of the guiding sliders 16 is two, and both the guiding slider 16 and the sliding plate 9 are T-shaped;

[0036] The limiting component includes:

[0037] A positioning ear 11 is connected to the side surface of the sliding plate 9, and a fixing threaded hole is formed on the surface of the positioning ear 11. A fixing threaded rod 10 is meshingly connected inside the fixing threaded hole. Preferably, the number of the positioning ears 11 is two;

[0038] A plurality of fixing threaded grooves 8 are formed on the surface of the support base 1, and the inner diameters of the fixing threaded grooves 8 and the fixing threaded holes are the same as the outer diameter of the fixing threaded rod 10. Preferably, there are two groups of fixing threaded grooves 8 on the surface of the support base 1, and each group of fixing threaded grooves 8 is distributed on the surface of the support base 1 in a straight line and at equal distances.

[0039] When those skilled in the art use the above technical solutions to stably limit the lithium battery and perform charge and discharge detection on the lithium battery, it is found that it is still necessary to manually hold the charge and discharge detection instrument for a long time to perform charge and discharge operations on the lithium battery, which results in a reduction in the overall work efficiency.

[0040] In this embodiment, to address the above technical problem, after stably limiting the lithium battery inside the storage card slot 12, the staff can place the detection instrument between the limiting strip 6 and the fixed block 2, and make the detection instrument contact the surface of the support base 1. Subsequently, slide the sliding plate 9 on the surface of the support base 1 towards the direction of the fixed block 2 until the limiting strip 6 on the sliding plate 9 presses the detection instrument against the surface of the fixed block 2. Then, the staff sequentially screw the fixing threaded rod 10 into the fixing threaded hole and the fixing threaded groove 8 aligned with the fixing threaded hole to stably limit the sliding plate 9 on the support base 1, so that the detection instrument is stably limited on the fixed block 2 by the limiting strip 6.

[0041] Through the above technical solution, after the lithium battery is stably positioned, the detection instrument for detecting the charging and discharging of the lithium battery can be conveniently and stably positioned on one side of the lithium battery, so that the staff does not need to hold the detection instrument for a long time to detect the charging and discharging of the lithium battery, improving the working efficiency of the lithium battery charging and discharging detection device.

[0042] Preferably, several second balls 18 and first balls 17 are respectively installed on both sides of the surface of the guiding slider 16, and both the second balls 18 and the first balls 17 are in contact with the inner wall of the guiding chute 7. Thus, when the sliding plate 9 is pushed to move, the guiding slider 16 on the sliding plate 9 can move more smoothly inside the guiding chute 7.

[0043] Such as Figure 1 and Figure 5 As shown in, in an embodiment of the present invention, a cavity is formed inside the fixed block 2, and a buffer spring 22 is installed inside the cavity. One end of the buffer spring 22 is connected to a second movable plate 21, and a support rod 20 is connected to the surface of the second movable plate 21. The end of the support rod 20 away from the second movable plate 21 is connected to a first movable plate 19, and a buffer rod 4 is installed on the surface of the first movable plate 19. A through hole is formed on the surface of the fixed block 2, and the buffer rod 4 is disposed through the inside of the through hole.

[0044] In this embodiment, by providing the buffer rod 4 supported by the buffer spring 22, the entire detection device can move up and down during operation to ensure the stability of the detection device.

[0045] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
