Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery detection, and particularly relates to a portable lithium battery detection device. Background Technique

[0002] Lithium battery detection refers to a series of tests and evaluations on lithium batteries to determine the performance, status and safety of the batteries. These tests include appearance inspection, voltage test, capacity test, internal resistance test, cycle life test, temperature detection and safety test, etc. Through these detections, the health status and service life of lithium batteries can be understood to ensure their operation within a safe range. Currently, a resistance detector is often used to detect batteries. However, during the detection process, currently, the detector is held by the operator's two hands respectively, and then the two detection ends are respectively contacted with the positive and negative electrodes of the battery to achieve detection. Since two hands are required for operation, the operator cannot operate the detector anymore, resulting in inconvenience during detection. Therefore, we introduce a portable lithium battery detection device. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a portable lithium battery detection device, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A portable lithium battery detection device includes a resistance detector. A first wire and a second wire are fixedly connected to the upper end of the resistance detector. The first wire is located in front of the second wire. The ends of the first wire and the second wire far from the resistance detector are jointly fixedly connected with a clamping device. The clamping device is located behind the resistance detector. A display screen is fixedly connected to the upper right part of the resistance detector, and a control button is fixedly connected to the lower right part of the resistance detector. Connecting blocks are fixedly connected to the upper part and the lower part of the front end of the resistance detector respectively. One ends of the two connecting blocks close to each other are jointly movably connected through a rotating shaft with a battery holder.

[0006] Preferably, the clamping device includes a frame. The frame is of a "U" - shaped structure. Two reinforcing plates are fixedly connected to the upper part and the lower part of the front inner wall of the frame respectively. A second contact is fixedly inserted and connected to the upper end of the frame, and a first contact is movably inserted and connected to the lower end of the frame. A spring is sleeved on the outer surface of the first contact.

[0007] By adopting the above technical solution: The reinforcing plates improve the strength of the frame and prevent the frame from deforming and breaking during detection.

[0008] Preferably, a first limiting plate is fixedly connected to the upper part of the outer surface of the first contact, and a second limiting plate is fixedly connected to the lower end of the first contact.

[0009] Preferably, the second limiting plate is located at the lower end of the frame.

[0010] Preferably, the No. 2 contact is a structure that is wide at the top and narrow at the bottom, the No. 1 contact is a structure that is narrow at the top and wide at the bottom, the No. 2 contact is fixedly connected to the No. 2 wire, and the No. 1 contact is fixedly connected to the No. 1 wire.

[0011] Preferably, the battery rack is a "U"-shaped structure.

[0012] Preferably, a plurality of No. 1 battery slots are opened at the left portion of the rear end of the battery rack, and a plurality of No. 2 battery slots are opened at the right portion of the rear end of the battery rack.

[0013] By adopting the above technical solution, there are gaps between a plurality of No. 1 battery slots and a plurality of No. 2 battery slots, which facilitates their distinction.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, by setting a clamping device, the No. 2 contact is connected to the No. 2 wire, the No. 1 contact is connected to the No. 1 wire, the No. 1 contact is pressed downward to move the No. 1 contact downward, so that the No. 1 contact and the No. 2 contact are separated from each other, and then the cylindrical lithium battery is placed between the No. 2 contact and the No. 1 contact, and the No. 1 contact is released. Under the elastic action of the spring, the No. 1 contact is pushed up by the spring, so that the No. 1 contact and the No. 2 contact are close to each other, so that the No. 1 contact cooperates with the No. 2 contact to clamp the two ends of the battery. On the one hand, the battery test can be carried out without manual holding, and on the other hand, it is also suitable for the test of batteries of different sizes;

[0016] 2. In the utility model, by connecting the battery rack to the resistance tester, and the battery rack is movably connected to the resistance tester through two connecting blocks at the front end of the resistance tester, the angle of the battery rack can be freely adjusted.

[0026] A portable lithium battery testing device comprises a resistance tester 1, wherein a No. 1 wire 2 and a No. 2 wire 3 are fixedly connected to the upper end of the resistance tester 1, the No. 1 wire 2 is located in front of the No. 2 wire 3, the No. 1 wire 2 and the No. 2 wire 3 are fixedly connected to a clamping device 4 at one end away from the resistance tester 1, the clamping device 4 is located at the rear of the resistance tester 1, a display screen 6 is fixedly connected to the upper right end of the resistance tester 1, a control button 5 is fixedly connected to the lower right end of the resistance tester 1, a connecting block 8 is fixedly connected to the upper front end and the lower front end of the resistance tester 1, and a battery rack 7 is movably connected to the two connecting blocks 8 at ends close to each other through a rotating shaft.

[0027] In this embodiment, the clamping device 4 includes a frame 41, and the frame 41 is a "U"-shaped structure. Two reinforcement plates 45 are fixedly connected to the upper part and the lower part of the front inner wall of the frame 41. A No. 2 contact 44 is inserted and fixedly connected to the upper end of the frame 41, and a No. 1 contact 42 is inserted and movably connected to the lower end of the frame 41. A spring 43 is sleeved on the outer surface of the No. 1 contact 42; a No. 1 limit plate 421 is fixedly connected to the upper part of the outer surface of the No. 1 contact 42, and a No. 2 limit plate 422 is fixedly connected to the lower end of the No. 1 contact 42; the No. 2 limit plate 422 is located at the lower end of the frame 41; the No. 2 contact 44 is a structure that is wide at the top and narrow at the bottom, and the No. 1 contact 42 is a structure that is narrow at the top and wide at the bottom. The No. 2 contact 44 is fixedly connected to the No. 2 wire 3, and the No. 1 contact 42 is fixedly connected to the No. 1 wire 2.

[0028] Through the above scheme: press down the No. 1 contact 42 to make the No. 2 contact 44 and the No. 1 contact 42 move away from each other, put the battery between the No. 1 contact 42 and the No. 2 contact 44, release the No. 1 contact 42, and under the elastic action of the spring 43, the No. 1 contact 42 is pushed up, so that the No. 1 contact 42 and the No. 2 contact 44 clamp the battery.

[0029] In this embodiment, the battery rack 7 is a "U"-shaped structure; a plurality of No. 1 battery slots 71 are opened at the left rear end of the battery rack 7, and a plurality of No. 2 battery slots 72 are opened at the right rear end of the battery rack 7.
