Description

Technical Field

[0001] This utility model relates to the technical field of internal electrode group positioning brackets for lead-acid batteries, specifically a novel positioning bracket for lead-acid batteries. Background Technology

[0002] Tubular plate valve-regulated sealed gel lead-acid batteries are a type of valve-regulated sealed lead-acid battery that uses a tubular plate design and a gel electrolyte. The electrolyte is in a gel state, exhibiting high stability, long lifespan, and excellent high and low temperature resistance. Tubular plates are one type of 'plate' structure used in lead-acid batteries. Unlike 'sheet plates,' which involve coating the active material paste onto a 'grid-like lead plate,' tubular plates involve extruding the active material paste into a 'cylindrical fiber tube.' Lead-acid batteries are typically installed using positioning brackets in 'vertical,' 'horizontal,' or 'side-mounted' configurations.

[0003] Existing positioning brackets for horizontal installation of lead-acid batteries cannot prevent cracking of the welding joints between the tabs and the busbars due to equipment vibration during use, which will affect the normal use of the battery. Secondly, the plates may also bend or deform under the influence of gravity.

[0004] Therefore, those skilled in the art have provided a novel positioning bracket for lead-acid batteries to solve the problems mentioned in the background art. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a novel positioning bracket for lead-acid batteries. By setting a positioning mechanism, when the lead-acid battery is installed horizontally, it can prevent the plates from bending or deforming due to gravity, and prevent the welding joint between the tabs and the busbar from cracking due to equipment vibration. This greatly ensures the normal use of the horizontal installation method of the battery. Furthermore, by setting a locking mechanism, the limiting buckle can be fixed based on the external frame, preventing the limiting buckle from falling off during use and ensuring the overall stability of the positioning bracket, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel positioning bracket for lead-acid batteries includes an upper positioning bracket with a positioning mechanism. The positioning mechanism includes an outer frame fixedly connected to the lower end of the upper positioning bracket, a lower positioning bracket fixedly connected to the lower end of the outer frame, a limit block fixedly connected to the side wall of the outer frame, a limit strip provided on the outer frame, and a limit slot provided on the limit strip, the limit slot being adapted to the limit block.

[0008] As a further embodiment of this utility model, the upper positioning bracket, the outer frame and the lower positioning bracket are provided in two sets, which are stacked together. The front and rear ends of the two outer frames are fixedly connected to limit blocks. The two ends of the limit buckle are provided with limit slots, and the limit slots are adapted to the limit blocks one by one.

[0009] As a further improvement of this utility model, the front and rear ends of the outer frame are provided with limit buckles, and the two limit buckles are sleeved on the limit block through limit slots.

[0010] As a further embodiment of this utility model, the limiting block is provided with a locking mechanism, the locking mechanism including a spring rod fixedly connected inside the limiting block, a trapezoidal block fixedly connected to the upper end of the spring rod, a movable rod fixedly connected to the upper end of the trapezoidal block, and limiting strips slidably connected to both sides of the limiting block, one end of the limiting strip contacting the side wall of the trapezoidal block.

[0011] As a further embodiment of this utility model, the upper end of the movable rod extends through to the outside of the limiting block, and the end of the limiting strip away from the trapezoidal block extends through to the outside of the limiting block.

[0012] As a further improvement of this utility model, the lower surface of the limiting strip is in full contact with the upper surface of the limiting buckle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting up a positioning mechanism, when installing lead-acid batteries horizontally, it can prevent the plates from bending or deforming due to gravity, and prevent the welding parts between the tabs and the busbars from cracking due to equipment vibration. This greatly ensures the normal use of the horizontal installation method of the battery. Secondly, by setting up a locking mechanism, the limit strip can be fixed based on the external frame to prevent the limit strip from falling off during use and ensure the overall stability of the positioning bracket.

[0020] Please see Figures 1-4 In this embodiment of the utility model, a novel positioning bracket for a lead-acid battery includes an upper positioning bracket 1. An outer frame 2 is fixedly connected to the lower end of the upper positioning bracket 1, and a lower positioning bracket 3 is fixedly connected to the lower end of the outer frame 2. Two sets of upper positioning bracket 1, outer frame 2, and lower positioning bracket 3 are provided, respectively corresponding to the thickness surfaces on both sides of the tubular electrode plate at the bottom of the electrode group. Limiting blocks 4 are fixedly connected to the front and rear ends of the outer frame 2. Limiting strips 5 are provided at the front and rear ends of the two outer frames 2. Limiting slots 6 are provided at both ends of the limiting strips 5. By aligning the limiting slots 6 with the limiting blocks 4, the limiting strips 5 can be installed based on the outer frame 2, and the installation of the positioning bracket can be completed.

[0021] A spring rod 9 is fixedly connected inside the limiting block 4. A trapezoidal block 8 is fixedly connected to the upper end of the spring rod 9. A movable rod 7 is fixedly connected to the upper end of the trapezoidal block 8. The upper end of the movable rod 7 extends through to the outside of the limiting block 4. When the limiting block 4 is manually pushed to move inward, it will cause the trapezoidal block 8 to move downward, thus squeezing the spring rod 9. Limiting strips 10 are slidably connected to both sides of the limiting block 4. When the trapezoidal block 8 moves downward, it will no longer limit the limiting strip 10. When it moves upward, it will push the limiting strip 10 to move outward from the limiting block 4. After the limiting buckle 5 is installed, the limiting strip 10 can limit the limiting buckle 5 from the outside to prevent it from falling off.

[0022] The working principle of this utility model is as follows: When it is necessary to install a positioning bracket on a lead-acid battery, firstly, the upper tubular electrode plate locking points of the positioning plate composed of two upper positioning brackets 1, an outer frame 2, and a lower positioning bracket 3 can be respectively locked onto the thickness surfaces on both sides of the tubular electrode plate at the bottom of the electrode group. Then, the limiting slots 6 at both ends of the limiting buckle 5 are aligned with the limiting blocks 4 on the side wall of the outer frame 2. At this time, the movable rod 7 can be pushed into the limiting block 4. When the movable rod 7 moves, it can drive the trapezoidal block 8 to move synchronously and realize the compression of the spring rod 9. When the trapezoidal block 8 moves, it loses its restraint on the limiting strip 10. At this time, the limiting strip 10 can be moved inward to the limiting block 4, and then the limiting buckle 5 can be pressed onto the limiting block 4 to complete the initial fixation. Then, the movable rod 7 is released. At this time, under the action of the spring rod 9, the trapezoidal block 8 and the movable rod 7 return to their original positions. When the trapezoidal block 8 moves, it can push the limiting strip 10 to move outward again to the limiting block 4 to complete the fixation of the limiting buckle 5. At this time, the installation of the limiting buckle 5 can be completed based on the outer frame 2, thereby realizing the installation of the positioning bracket.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
