Detailed Implementation

[0017] 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.

[0018] Example 1 like Figure 1-5 As shown, this embodiment provides a lead-acid battery maintenance device for discharging, maintaining, and fixing a lead-acid battery 100. It includes a mounting box 1, with a cover plate 103 hinged to the lower part of the mounting box 1. The cover plate 103 and the mounting box 1 are locked together by a locking device 2. A fixing seat 3 is installed on the top of the inner wall of the mounting box 1. Cylinders 4 are installed at both ends of the fixing seat 3. The output end 41 of the cylinders 4 is connected to a clamping plate 5. A load plate 6 is detachably mounted on the bottom of the clamping plate 5 via bolts 61. A clamping groove 62 is formed in the inner opening of the load plate 6, and the lead-acid battery 100 is clamped between the clamping grooves 62.

[0019] Cylinder 4 is mounted mirror images of each other along the central axis of mounting box 1. Clamping plate 5 and load plate 6 are arranged in an "L" shape after installation.

[0020] The cover plate 103 has an external mounting handle 102. The cover plate 103 and the mounting box 1 are hinged together by a hinge seat 101.

[0021] Mounting box 1 serves as the main frame, supporting the battery and its fixing mechanism. A cover plate 103 is hinged to the lower part of the mounting box to close the battery compartment. A hinge seat 101 connects the cover plate to the mounting box via a hinge structure. A handle 102 is mounted on the outside of the cover plate for easy opening and closing.

[0022] The mounting base 3 is installed on the top of the inner wall of the mounting box to support the cylinder mechanism. The cylinder 4 is the power element that drives the clamping action and is arranged in a mirror-symmetrical manner. The clamping plate 5 is directly connected to the clamping component at the output end of the cylinder and is fixed to the load plate 6 by bolts. The load plate 6 is a detachable component, and its bottom is connected to the clamping plate 5 by bolts 61 to form an "L"-shaped structure. The groove opened in the inner opening of the clamping slot 62 is used to directly clamp the lead-acid battery 100.

[0023] The locking device 2 includes a vertical rod 21, a horizontal rod 22, a locking block I 23, a T-shaped movable rod 25, and a locking block II 26. The vertical rod 21 is installed on the inner wall of one end of the cover plate 103, and the horizontal rod 22 is fixed to the top left side of the vertical rod 21. The locking block I 23 is fixed to the lower side of the horizontal rod 22. A guide hole 24 is opened on the outer wall of the mounting box 1, and the T-shaped movable rod 25 passes through the guide hole 24 to connect the locking block II 26. The locking block I 23 and the locking block II 26 are rotated and engaged.

[0024] The T-shaped movable rod 25 is located on the outer wall of the mounting box 1 and is wound with the spring 27.

[0025] Initially, spring 27 is compressed. When needed, the operator pushes cover 103 inward, causing vertical rod 21 to swing inward, which in turn causes horizontal rod 22 to swing inward, and vertical rod 62 to swing inward, causing locking block I 23 to swing. Locking block I 23 disengages from locking block II 26. Due to the action of spring 27, T-shaped movable rod 25 moves, causing locking block II 26 to move outward to a suitable position, allowing the operator to open cover 103 for use of lead-acid battery 100. After the lead-acid battery 100 is tested, cover 3 can be pulled upward to reset, and then T-shaped movable rod 25 can be pushed to the right. Spring 27 is compressed, and T-shaped movable rod 25 moves to the right, causing locking block II 26 to move to the right. When locking block II 26 moves to the right below locking block I 23, T-shaped movable rod 25 can be released. Due to the action of spring 27, locking block II 26 and locking block I 23 cooperate to fix cover 103.

[0026] In its specific operation, the mounting box 1 serves as the main frame, with its lower part hinged to the cover plate 103 via a hinge seat 101, forming an openable and closable battery compartment. The cover plate 103 is locked to the mounting box 1 via a locking device 2, and a spring 27 ensures that the T-shaped movable rod 25 automatically resets, achieving stable locking.

[0027] The mounting base 3 is installed on the top of the inner wall of the mounting box 1, with cylinders 4 symmetrically arranged at both ends. The cylinder output end 41 is connected to the clamping plate 5. The clamping plate 5 is fixed to the load plate 6 by bolts 61, forming an "L" shaped clamping structure. The clamping groove 62 of the load plate 6 directly contacts both sides of the lead-acid battery 100.

[0028] Battery placement stage: Pull out handle 102 to release the engagement of locking device 2, locking block I 23 and locking block II 26, and flip down cover 103 to open the mounting box. Place lead-acid battery 100 into mounting box 1, and initially align its side with the clamping groove 62 of load plate 6.

[0029] Clamping and fixing stage: When cylinder 4 is activated, its output end 41 pushes clamping plate 5 and load plate 6 horizontally toward lead-acid battery 100, clamping both sides of the battery through clamping groove 62 to prevent shaking. The "L"-shaped structure ensures that the bottom of the battery is suspended, facilitating heat dissipation and preventing displacement.

[0030] Locking and maintenance stage: When the cover plate 103 is closed, the vertical rod 21 moves the horizontal rod 22 and the locking block I 23 upwards. The T-shaped movable rod 25 is reset under the action of the spring 27, causing the locking block II 26 to rotate and engage with the locking block I 23, thus completing the locking. The battery is discharged and maintained in a fixed state, with the clamping force evenly distributed to avoid poor electrode contact.

[0031] Disassembly stage: After maintenance, manually pull out the T-shaped movable rod 25 to release the locking block and open the cover 103. The cylinder 4 retracts, releasing the battery, allowing for quick replacement of load plates 6 of different specifications to accommodate new battery models.

[0032] This novel design utilizes a mirror-arranged cylinder-driven clamping plate and load plate to form an "L"-shaped clamping structure. This, combined with the clamping slots, precisely secures the battery, preventing movement and improving discharge stability. The detachable load plate design allows for quick replacement of clamping slots of different sizes, accommodating various battery models.

[0033] The locking device uses locking blocks I and II to rotate and engage, combined with a spring-loaded T-shaped movable rod for automatic return, ensuring the cover is securely locked and preventing accidental opening. The hinged base and handle design simplify the opening and closing process, making it easy for maintenance personnel to operate.

[0034] The above description is merely an illustrative example of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in the claims, all of which should fall within the protection scope of this utility model.
