Description

Technical Field

[0001] This utility model relates to the field of probe technology for lithium battery testing, specifically to a lithium battery test probe. Background Technology

[0002] There are many types of lithium batteries, and even the common cylindrical shapes vary. Some cylindrical batteries have their positive and negative electrodes located at both ends, while others integrate the positive and negative electrodes at one end, with the positive electrode in the middle and the negative electrode around the positive electrode. There are also flat lithium batteries. The application areas of various lithium batteries are also different, but their main functions are the same: to store electricity and power some devices.

[0003] To ensure normal charging and discharging of batteries, it is necessary to test the positive and negative electrodes. This testing is done using probes. However, setting up the probes for batteries where both the positive and negative electrodes are on the same end is problematic. Since the positive and negative probes are concentrated at one end and operate independently, the installation space requirements are very high. Furthermore, because they are independent of each other, disassembly and assembly are also affected and become cumbersome. At the same time, the installation positions of probes of different sizes need to be changed accordingly. Due to the above problems, changing the probes becomes cumbersome. Therefore, a lithium battery test probe is proposed. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: a lithium battery test probe, including a lamp holder, an inner groove is opened inside the lamp holder, a protective post is fixedly connected to the middle of one side wall of the lamp holder, the protective post is a ring structure and communicates with the inside of the inner groove, a positive electrode probe is inserted through the middle of the protective post, four movable grooves are opened through the side wall of the lamp holder and communicate with the inside of the inner groove, a negative electrode probe is slidably connected in the movable groove, a side plate is fixedly connected to one end of the negative electrode probe in the inner groove, a screw is threaded through the side plate, a bevel gear is fixedly connected to one end of the screw, and a toothed ring is meshed with the bottom of the bevel gear.

[0005] As a preferred technical solution of this utility model, the top of the toothed ring is an inclined structure opposite to the bevel gear and is fixedly connected with teeth. The bottom side wall of the lamp holder is provided with an annular rotating groove. A rotating ring is rotatably connected in the rotating groove. The toothed ring is fixedly connected to one end of the rotating ring through the bottom end. The rotating ring is an annular structure. An annular toggle plate is fixedly connected to the outer wall of the rotating ring.

[0006] As a preferred technical solution of this utility model, an annular limiting groove is provided on one side wall of the rotating groove, and a positioning ring is rotatably connected in the limiting groove. The positioning ring is fixedly connected to the inner wall of the rotating ring at one end.

[0007] As a preferred technical solution of this utility model, four fixing plates are fixedly connected to the inner groove and the side wall near the positive probe. One end of the screw is rotatably connected to one side wall of the fixing plate. The bottom ends of the positive probe and the negative probe are connected to wires, which are inserted and connected to the bottom side wall of the lamp holder.

[0008] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to one end of the positive electrode probe located in the inner groove, a spring is fixedly connected to the bottom of the fixing plate, one end of the spring is fixedly connected to the bottom side wall of the inner groove, and an annular connecting post is fixedly connected to the bottom outer wall of the lamp holder.

[0009] This invention has the following advantages: Four movable slots are opened on the side wall of the lamp holder, and a negative electrode probe is slidably installed in each movable slot. The positive electrode probe is installed in the middle of the lamp holder. In this way, the negative electrode probe and the positive electrode probe can be installed together on one lamp holder, saving the space required for installation, and without affecting the independent operation of the negative electrode probe and the positive electrode probe. Furthermore, the rotating connecting column drives the toothed ring to drive the screw to rotate via the bevel gear, thereby driving the negative electrode probe to slide along the movable slot. This allows for the detection of batteries of different sizes. Since the center point is fixed, only the position of the negative electrode probe needs to be adjusted to detect the positive and negative electrodes of batteries of different sizes, improving the convenience of operation.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figure 1-3This utility model discloses a lithium battery test probe, including a lamp holder 1, an inner groove 7 inside the lamp holder 1, a protective post 4 fixedly connected to the middle of one side wall of the lamp holder 1, the protective post 4 having a ring structure and communicating with the inside of the inner groove 7, a positive electrode probe 5 inserted through the middle of the protective post 4, four movable grooves 2 through the side wall of the lamp holder 1, and the movable grooves 2 communicating with the inside of the inner groove 7, a negative electrode probe 3 slidably connected in the movable grooves 2, a side plate 10 fixedly connected to one end of the negative electrode probe 3 located in the inner groove 7, a screw 12 threadedly inserted in the side plate 10, a bevel gear 16 fixedly connected to one end of the screw 12, and a toothed ring 17 meshing with the bottom of the bevel gear 16;

[0016] The top of the gear ring 17 is an inclined structure opposite to the bevel gear 16 and is fixedly connected with teeth. The bottom side wall of the lamp holder 1 is provided with an annular rotating groove 18. A rotating ring 13 is rotatably connected in the rotating groove 18. The gear ring 17 is fixedly connected to one end of the rotating ring 13 through its bottom end. The rotating ring 13 is an annular structure. An annular actuating plate 6 is fixedly connected to the outer wall of the rotating ring 13. An annular limiting groove 19 is provided on one side wall of the rotating groove 18. A positioning ring 20 is rotatably connected in the limiting groove 19. One end of the positioning ring 20 is fixedly connected to the inner wall of the rotating ring 13. Four fixing plates 11 are fixedly connected in the inner groove 7 and on the side wall near the positive electrode probe 5. One end of the screw 12 is rotatably connected to one side wall of the fixing plate 11.

[0017] The technical effect of this solution is as follows: rotating the toggle plate 6 drives the rotating ring 13 to rotate, which in turn drives the gear ring 17 to rotate synchronously, thereby driving the bevel gear 16 and the screw 12 to rotate. As the screw 12 rotates, it drives the negative electrode probe 3 to move back and forth along the moving groove 2. By adjusting the position of the four negative electrode probes 3, cylindrical batteries of different sizes can be tested. Because the position of the positive electrode probe 5 is fixed, the distance between the negative electrode probe 3 and the positive electrode probe 5 can be ensured to be the same, avoiding probe skew and affecting the test effect. In this way, the position of the negative electrode probe 3 can be adjusted very conveniently without cumbersome disassembly and assembly. Furthermore, by independently connecting the negative electrode probe 3 and the positive electrode probe 5 to the wires 15, the independence between the negative electrode probe 3 and the positive electrode probe 5 can still be guaranteed.

[0018] Both the positive probe 5 and the negative probe 3 are connected to the bottom of a wire 15. The wire 15 is inserted and connected to the bottom side wall of the lamp holder 1. The positive probe 5 is fixedly connected to a fixing plate 8 on the side wall of one end inside the inner groove 7. A spring 9 is fixedly connected to the bottom of the fixing plate 8. One end of the spring 9 is fixedly connected to the bottom side wall of the inner groove 7. An annular connecting post 14 is fixedly connected to the bottom outer wall of the lamp holder 1.

[0019] The technical effect of this solution is as follows: the fixed plate 8 and spring 9 can alleviate the resistance force on the positive electrode probe 5, and the extension of the spring 9 can ensure that the positive electrode probe 5 is stably pressed against the center point of the battery. Sufficient length of wire 15 is reserved in the inner groove 7, so that the wire 15 can move synchronously with the movement of the negative electrode probe 3, avoiding the problem that the length of the wire 15 is insufficient and will affect the movement adjustment of the negative electrode probe 3.

[0020] Specifically, when using this utility model, the lamp holder 1 is connected to the designated position via the connecting post 14, and the wire 15 is connected to the detection device. Then, the center point of the battery is aligned with the positive probe 5, and the battery is pressed onto the positive probe 5. This ensures that the negative probe 3 is also against the end of the battery, allowing the positive and negative terminals of the battery to be detected. Rotating the toggle plate 6 drives the gear ring 17 to rotate synchronously, and then drives the bevel gear 16 to rotate synchronously through the meshing connection principle. This drives the screw 12 to rotate, and through the threaded connection, drives the side plate 10 and the negative probe 3 to move. This allows the position of the four negative probes 3 to be adjusted simultaneously, thereby adapting to batteries of different sizes and improving the flexibility of application and the convenience of adjustment.

[0021] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0022] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
