Description

Technical Field

[0001] This utility model relates to the field of battery electrode protection cover technology, specifically an electrode protection cover connection structure. Background Technology

[0002] A car battery, also called a storage battery, is a type of battery that converts chemical energy into electrical energy. Usually, when people refer to a car battery, they are referring to a lead-acid battery. This type of battery is primarily made of lead and its oxides, and its electrolyte is a sulfuric acid solution. Car batteries supply power to the car's electrical system through positive and negative terminals on their surface. To prevent accidental short circuits caused by metal-to-metal connections between the positive and negative terminals, protective covers are typically installed on the surface of the terminals.

[0003] Currently, existing protective covers are usually made by injection molding, so that the protective cover is fitted onto the surface of the positive and negative electrode posts by interference fit. However, due to the different models of car batteries, the diameters of the positive and negative electrode posts are different. As a result, a protective cover of a certain model can only protect positive and negative electrode posts of a specific diameter, which has low applicability. Based on this, an electrode protective cover connection structure that solves the above problems is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an electrode protection cover connection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrode protection cover connection structure, including a storage battery, wherein the storage battery is provided with two electrode posts, characterized in that: a female cover is sleeved on the surface of the electrode posts, a protective groove is provided at the lower end of the female cover, a plurality of contact springs are installed in a circumferential array on the inner wall of the protective groove, the contact springs are L-shaped, a toggle ring is slidably installed below the contact springs inside the protective groove, and a daughter cover is installed at the upper end of the female cover in a liftable manner, the lower end of the daughter cover is located between the contact springs and the female cover.

[0006] Preferably, the upper end of the female cover is provided with a threaded hole, the surface of the female cover is provided with threads, and the female cover is threadedly connected to the inside of the threaded hole.

[0007] Preferably, a toggle block is installed on the upper end of the sub-cover, and the toggle block is cross-shaped.

[0008] Preferably, the surface of the female cover below the contact spring is provided with a plurality of sliding grooves arranged in a circumferential array. A connecting rod is slidably installed inside each sliding groove. One end of each of the connecting rods is connected to a toggle ring, and the other end of each of the connecting rods is provided with a removal ring, which is sleeved on the outside of the female cover.

[0009] Preferably, the plurality of sliding grooves are located on the surface of the cover between two contact springs.

[0010] Preferably, the width of the sliding groove matches the width of the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The electrode protection cover connection structure, by setting a female cover and a female cover, will press the contact spring when the female cover rotates and moves down, so that the contact spring and the electrode post surface are in contact, effectively preventing the female cover and the female cover from accidentally falling off the electrode post surface. At the same time, the contact spring is suitable for electrode posts of various diameters, which has a certain applicability and eliminates the need for multiple specifications of protective covers based on the electrode post diameter.

[0013] 2. The electrode protection cover connection structure is equipped with components such as a toggle ring, a connecting rod, and a removal ring. By moving the removal ring upward, the removal ring drives the toggle ring upward through the connecting rod. The toggle ring toggle the contact spring upward, so that the contact spring is released from contact with the electrode post, making it easy to remove the female cover and the female cover.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 4 As shown, the electrode protection cover connection structure of this embodiment includes a battery 1. The battery 1 is provided with two electrode posts 2, which are the positive and negative terminals of the battery. A female cover 3 is sleeved on the surface of the electrode posts 2. A protective groove 12 is provided at the lower end of the female cover 3. The protective groove 12 is used to protect the electrode posts 2. Multiple contact springs 4 are installed in a circumferential array on the inner wall of the protective groove 12. The contact springs 4 are L-shaped. A toggle ring 5 is slidably installed below the contact springs 4 inside the protective groove 12. A daughter cover 6 is installed on the upper end of the female cover 3 in a liftable manner. The lower end of the daughter cover 6 is located between the contact springs 4 and the female cover 3. By moving the daughter cover 6 down, the lower end of the daughter cover 6 will press the contact springs 4, thereby making the multiple contact springs 4 and the surface of the electrode posts 2 fit together, effectively preventing the female cover 3 from accidentally falling off the surface of the electrode posts 2. Moreover, the contact springs 4 are suitable for electrode posts 2 of various diameters and have a certain degree of applicability.

[0022] Specifically, the upper end of the female cover 3 is provided with a threaded hole 7, and the surface of the female cover 6 is provided with threads. The female cover 6 is threadedly connected to the inside of the threaded hole 7. By rotating the female cover 6, the female cover 6 can be raised and lowered, so that the lower end of the female cover 6 can press the contact spring 4.

[0023] Furthermore, a toggle block 8 is installed on the upper end of the sub-cover 6. The toggle block 8 is cross-shaped. The toggle block 8 is designed to facilitate the rotation of the sub-cover 6 and effectively prevent accidental slippage when rotating the sub-cover 6.

[0024] Furthermore, several sliding grooves 9 are arranged in a circumferential array on the surface of the female cover 3 below the contact spring 4. Connecting rods 10 are slidably installed inside each sliding groove 9. One end of each connecting rod 10 is connected to the actuating ring 5, and the other end of each connecting rod 10 is connected to a removal ring 11. The removal ring 11 is sleeved on the outside of the female cover 3. By moving the removal ring 11 upward, the removal ring 11 drives the actuating ring 5 through the connecting rods 10 to push the contact spring 4 upward, so that the contact spring 4 does not contact the surface of the electrode post 2, making it convenient to remove the female cover 3 from the surface of the electrode post 2.

[0025] Furthermore, several sliding grooves 9 are located on the surface of the cover 3 between two contact springs 4. When the connecting rod 10 rises inside the sliding grooves 9, the contact springs 4 will not come into contact with the connecting rod 10, thus avoiding affecting the normal upward movement of the connecting rod 10.

[0026] Furthermore, the width of the sliding groove 9 matches the width of the connecting rod 10, and both ends of the connecting rod 10 contact the inner wall of the sliding groove 9. Under the action of no external force, the connecting rod 10 and the removal ring 11 will not move.

[0027] The method of use in this embodiment is as follows: By fitting the female cover 3 onto the surface of the electrode post 2 of the battery 1, the electrode post 2 is positioned between multiple contact springs 4. Then, the female cover 6 is installed. By rotating, the female cover 6 is moved downward, and the lower end of the female cover 6 presses against the contact springs 4. Since the contact springs 4 have an L-shaped structure, multiple contact springs 4 will contact the electrode post 2, thus protecting the electrode post 2 with the female cover 3 and the female cover 6. When it is necessary to remove them, the female cover 6 is moved upward by rotating. The female cover 6 does not press against the contact springs 4. Then, the removal ring 11 is lifted upward. The removal ring 11 drives the actuating ring 5 through the connecting rod 10 to move the contact springs 4 upward, releasing the contact springs 4 from the electrode post 2. The female cover 3 and the female cover 6 can then be removed.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
