Description

Technical Field

[0001] The utility model relates to a protective cover for a lead-acid battery, belonging to the technical field of lead-acid batteries. Background Art

[0002] During the storage and transportation of lead-acid batteries, it is necessary to protect the battery terminals. If the battery terminals are connected to other conductors such as metals, short circuits may occur, burning out the terminals and causing the battery to fail.

[0003] Currently, there are already some protections for battery terminals in the lead-acid battery market. For example, in the patent "A Protective Cap for Lead-Acid Battery Terminals", the authorization announcement number is CN220155719 U, which can be installed on the conical terminals of lead-acid batteries. It has a proper tightness and is not easy to fall off, and can prevent the battery terminals from connecting with other metals and causing sparking short circuits.

[0004] However, in the lead-acid battery market, a considerable part of the terminal states are angular terminals, screw terminals, etc., and there are no protective devices, which poses risks. Summary of the Invention

[0005] The purpose of the utility model is to provide a protective cover for a lead-acid battery to overcome the above deficiencies. The protective cover is designed with an inverted buckle, which is installed on the lead-acid battery. The inverted buckle can hook the lower edge of the battery to avoid falling off and prevent short circuits of the lead-acid battery during storage and transportation.

[0006] The technical solution of the utility model is: a protective cover for a lead-acid battery, including a cover. Inside the cover, there are positioning columns that are in interference fit with the positioning holes of the battery. Outside the cover, there is a retaining edge. At the inner corner of the front side of the cover, there is a supporting retaining edge. The end face of the supporting retaining edge has a stop face for cooperating with the cover surface of the battery. Near the outer corner of the front side of the cover, there are hook claws for hooking the skirt of the large cover. The hook claws include an extension rib and an inverted buckle arranged at the end of the extension rib.

[0007] The positioning column includes a column body and rib strips connected to the side of the column body.

[0008] There are three rib strips, and the three rib strips are distributed around the side of the column body to form a triangular rib. The positioning hole is a blind hole, and there is a notch outside the blind hole. The surface of the triangular rib is in interference fit with the blind hole.

[0009] The lower end face of the rib strip is an inclined surface.

[0010] The retaining edge and the supporting retaining edge have the same height.

[0011] The extension rib is a bent rib strip composed of an upper rib and a lower rib connected to the upper rib. The included angle between the upper rib and the lower rib is an obtuse angle.

[0012] The cover is marked with positive and negative pole symbols.

[0013] There is an observation window A between the supporting rib and the hook claw.

[0014] The inner surface of the cover near the positioning post has a groove.

[0015] The groove is 2 mm wide and 1.5 mm deep.

[0016] The protective cover of the present utility model is installed on the lead-acid battery and is not easily detached; it can effectively protect the battery terminal post, prevent the battery terminal post from being bruised or damaged during handling; and prevent the battery terminal post from being connected to other metals and causing spark short circuit. For the terminal post states of various models of the battery, this kind of protective cover can be used, and the versatility is good. Installing the protective cover increases the aesthetic degree of the battery. Brief Description of the Drawings

[0023] Figure 1 、 2 In [specific embodiments], a positive protective cover 2 is installed outside the positive terminal post of the battery, and a negative protective cover 3 is installed outside the negative terminal post. The positive protective cover 2 and the negative protective cover 3 are in a mirror image relationship; the positive protective cover 2 and the negative protective cover 3 are collectively referred to as the protective cover. The protective cover is installed on the battery 1 and is not easily dropped; the product of the protective cover is marked with a positive sign and is installed on the positive side of the battery; the product of the protective cover 3 is marked with a negative sign and is installed on the negative side of the battery. Installing the protective cover on the battery 1 can protect the battery terminal post 8 and prevent it from being connected to other metals and causing spark short circuit.

[0024] Figure 3 、 4Inside, positioning posts 9 that are in interference fit with the positioning holes of the storage battery 1 stand upright on the inner side of the cover. A retaining edge stands upright on the outer side of the cover. There is a supporting retaining edge at the inner corner of the front side of the cover. The end face of the supporting retaining edge has a rabbet face 11 for mating with the cover face 5 of the storage battery 1. There is a claw for hooking the skirt edge 7 of the large cover near the outer corner of the front side of the cover. The claw includes an extension rib 13. The extension rib 13 is a bent rib formed by an upper rib and a lower rib connected to the upper rib. The angle between the upper rib and the lower rib is an obtuse angle, and the end of the lower rib is arranged at the undercut 12.

[0025] The storage battery 1 has two blind holes 4, which are in interference fit with the positioning posts 9 of the protective cover. During installation, the positioning posts 9 are inserted into the blind holes 4 for fixation. The rabbet face 11 fits with the cover face 5, and the undercut 12 hooks the skirt edge 7 of the large cover to prevent the protective cover from falling off.

[0026] There is a positive electrode symbol 6 on the cover face of the storage battery 1. The positive electrode symbol 6 indicates that this is the positive electrode side of the storage battery 1, and only the positive protective cover 2 can be installed.

[0027] The positioning posts 9 are made in the shape of triangular ribs. The middle is a column with a diameter of 2 mm, and 3 ribs extend from the side of the column, which are designed to be in interference fit with the blind holes 4.

[0028] The main glue thickness of the protective cover 2 is 2 mm, and the glue thickness of the groove 10 is 0.5 mm. The undercut 12 hooks the skirt edge 7 of the large cover to prevent the positioning posts 9 from being pulled out of the blind holes 4. The undercut 12 hooks the skirt edge 7 of the large cover. Due to the buffering effect of the groove 10, the positioning posts 9 will not become loose. Without this groove, when the undercut 12 hooks the skirt edge 7 of the large cover, the positioning posts 9 will tilt and become loose.

[0029] Figure 5 、 6 Inside, the protective cover 2 is installed on the storage battery 1, and the extension rib 13 will be squeezed and deformed. The deformed shape is shown as the extension rib 14. This squeezing and deforming force causes the undercut 12 to hook the skirt edge 7 of the large cover to prevent the protective cover from falling off.
