Description

Technical Field

[0001] This utility model belongs to the field of negative electrode post technology, specifically, it relates to a sealing clamp for a negative electrode post. Background Technology

[0002] With the rapid development of the new energy industry, energy storage devices such as lithium batteries and lead-acid batteries are being used more and more widely. As a key component connecting the battery to the external circuit, the sealing quality of the negative terminal directly affects the battery's safety, stability, and lifespan. In the manufacturing process of the negative terminal, the sealing process is the core link to ensure the sealing and electrical performance of the negative terminal, and high-quality sealing fixtures are the basic guarantee for achieving stable and efficient sealing.

[0003] Currently, existing negative electrode post sealing clamps on the market have many problems in practical applications. Some clamps use simple fixing methods, which result in insufficient positioning accuracy of the negative electrode post cover plate. This causes the cover plate and sealing plate to easily shift during the sealing process, leading to defects such as gaps and unevenness at the sealing joint, which seriously affects the sealing performance and appearance quality of the product.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A sealing clamp for a negative electrode post includes a sealing plate and a cover plate. The sealing plate has a placement slot, and the cover plate is placed inside the placement slot. Two flip plates are arranged above the sealing plate, which are used to press the cover plate. The sealing plate also has four rectangular slots, which are symmetrical to each other in pairs. Each of the four rectangular slots has a sliding plate inside, and each of the four sliding plates has a pressing block at its bottom, which is used to limit the position of the cover plate. The sealing plate also has two symmetrical mounting slots above it.

[0006] In a preferred embodiment of this utility model, each of the two flip plates is provided with a rotating rod at both ends, the four rotating rods are symmetrical to each other in pairs, and bearings are provided at opposite ends of the four rotating rods in pairs, the four bearings are symmetrical to each other in pairs, and the four bearings are respectively placed on the inner wall of the mounting slot.

[0007] In a preferred embodiment of this utility model, each of the four rectangular slots has a movable sliding groove on its opposite side wall, and each movable sliding groove is symmetrical to the other. Each movable sliding groove has a movable slider slidably disposed in its inner cavity, and each movable slider is symmetrical to the other.

[0008] In a preferred embodiment of this utility model, a reset spring is provided at the bottom of each of the movable sliders, and the end of each reset spring away from the movable slider is provided at the bottom of the inner cavity of the movable groove.

[0009] Compared with the prior art, the present invention has the following advantages: This utility model allows the cover plate to be placed into the slot opened inside the sealing plate. At this time, the operator will cover it with a flip plate. Therefore, the top of the cover plate can be limited by the flip plate. When the flip plate is closed, the pressing block can also press the bottom of the cover plate, thereby achieving clamping and limiting.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0014] like Figures 1 to 5As shown, a sealing clamp for a negative electrode post includes a sealing plate 1 and a cover plate 2. The sealing plate 1 has a placement slot 11, into which the cover plate 2 is placed. Two flip plates 3 are positioned above the sealing plate 1, pressing down on the top of the cover plate 2. The sealing plate 1 also has four rectangular slots 12, symmetrically arranged in pairs. Each of the four rectangular slots 12 has a sliding plate 4, and each of the four sliding plates 4 has a pressing block 41 at its bottom, used to limit the position of the cover plate 2. Two symmetrical mounting slots are also provided above the sealing plate 1. By placing the cover plate 2 into the placement slot 11 within the sealing plate 1, and then covering it with the flip plates 3, the top of the cover plate 2 can be limited by the flip plates 3. Furthermore, when the flip plates 3 are closed, the pressing blocks 41 press down on the top of the bottom of the cover plate 2, thus achieving clamping and limiting.

[0015] In a specific embodiment, each of the two flip plates 3 has a rotating rod 31 at both ends. The four rotating rods 31 are symmetrical to each other in pairs. Bearings 311 are provided at opposite ends of the four rotating rods 31 in pairs. The four bearings 311 are symmetrical to each other in pairs and are placed on the inner wall of the mounting slot. This configuration ensures that the flip plates 3 can be flipped.

[0016] Furthermore, each of the four rectangular slots 12 has a movable groove 121 on its opposite side wall. Each movable groove 121 is symmetrical to the others, and each movable groove 121 has a movable slider 122 slidably mounted inside it. Each movable slider 122 is also symmetrical to the others. In this configuration, when the flip plate 3 is closed, it can press the movable plate 4 to move vertically downward with the assistance of the movable grooves 121 and the movable sliders 122. When the movable plate 4 moves vertically downward, it can drive the pressing block 41 to move vertically downward, thereby pressing the bottom and top of the placed cover plate 2 through the pressing block 41, thus achieving the positioning of the cover plate 2.

[0017] Furthermore, each movable slider 122 is equipped with a return spring 123 at its bottom, with one end of each return spring 123 located at the bottom of the inner cavity of the movable slide groove 121, away from the movable slider 122. This configuration ensures that when the flip plate 3 is opened, the movable slider 122 can be reset with the assistance of the return spring 123.

[0018] The implementation principle of the sealing clamp for the negative terminal in this embodiment is as follows: First, the operator opens the flip plate 3 and places the cover plate 2 at an angle into the placement slot 11 on the sealing plate 1. Once the cover plate 2 is in the placement slot 11, the operator straightens it. After straightening, the operator rotates the flip plate 3 so that it covers the cover plate 2, thus positioning the top of the cover plate 2. When the flip plate 3 is closed, it presses the moving plate 4, which moves vertically downward with the assistance of the moving slide 121 and the moving slider 122. When the moving plate 4 moves vertically downward, it drives the pressing block 41 to move vertically downward, thus pressing the top of the bottom of the placed cover plate 2, thereby positioning the cover plate 2. After positioning, the operator connects the sealing plate 1 to the negative terminal post on the top of the battery, thus connecting the cover plate 2 to the negative terminal post, ensuring the stability of the sealing and preventing the cover plate 2 from shifting during the sealing process.
