Description

Technical Field

[0001] This utility model belongs to the field of battery auxiliary tool technology, and specifically relates to a battery cell pry bar repair auxiliary device. Background Technology

[0002] During long-term cyclic use, lead-acid batteries and power lithium-ion batteries will experience electrolyte loss due to evaporation and decomposition, leading to battery capacity decay. Performance can only be restored by replenishing electrolyte. Before replenishing electrolyte, the sealing aluminum sheet of the electrolyte inlet must be pried open, which is the core maintenance procedure.

[0003] Currently, this process is mostly done manually using common tools such as screwdrivers and metal pry bars. The battery filler neck is close to the positive and negative terminals, and the operating space is limited. When prying, uneven force can easily cause the tool to slip or shift, accidentally touching the positive and negative terminals and causing a short circuit. A short circuit will cause the battery to spark instantly, burning out the internal electrode structure and directly rendering the battery unusable. Furthermore, electrolyte leakage can corrode equipment and cause safety accidents.

[0004] Therefore, there is an urgent need for an auxiliary device that can accurately isolate and protect the positive and negative terminals when the sealing aluminum sheet is pried open, in order to solve the problem of battery scrapping caused by improper operation and improve maintenance safety and reliability. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a battery cell pry bar repair auxiliary device to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A battery cell prying nail repair auxiliary device includes a cover, which has a front and a back. The back of the cover is fitted onto the battery and has clearance grooves on both sides. A clearance notch is provided in the middle of the cover to facilitate the prying nail.

[0008] The card cover is attached to the battery to protect the terminal post. The recessed groove allows for quick positioning, making it easy for operators to quickly find the welding cap position and facilitate prying operations. This avoids battery arcing and damage due to improper operation, greatly improving work efficiency.

[0009] Preferably, the cover is made of insulating material.

[0010] The cover has insulating properties to avoid the risk of electrostatic discharge.

[0011] Preferably, a protective protrusion is installed on the front of the card cover corresponding to the clearance groove, and the protective protrusion protrudes from the front of the card cover.

[0012] Because the pole has a certain thickness, the wall at the top of the groove is relatively thin, and adding a protective protrusion can increase the protection of the pole.

[0013] Preferably, the cover includes a positive cover and a negative cover, and also includes an adapter component and a locking component. The positive cover and the negative cover are spliced ​​together by the adapter component to form the cover and locked by the locking component, with a clearance notch located between the positive cover and the negative cover.

[0014] The positive and negative electrode caps are spliced ​​together by an adapter component and locked by a locking component. The positive electrode cap can be freely adapted to different negative electrode caps to match batteries of different specifications, increasing flexibility.

[0015] Preferably, the adapter component includes a slide rod installed on the positive or negative electrode cover and a slide groove opened on the negative or positive electrode cover. Both the slide groove and the slide rod are on the same side as the clearance notch. The slide groove and the slide rod are slidably inserted into each other and are fixed relative to each other by a locking component.

[0016] By sliding and inserting the slide rail and slide bar and fixing them with the locking assembly, the positive and negative electrode covers can be moved closer or further apart to accommodate batteries of different lengths.

[0017] Preferably, a protective cover is installed on the side of the protective protrusion near the clearance notch.

[0018] Prying pins is usually done manually with tools such as screwdrivers. If the operation is accidentally damaged, the protective protrusion may be directly punctured. The protective cover can thicken the protective protrusion, which can better protect the terminal post. Moreover, if it is damaged, it can be replaced without affecting the overall use of the cover.

[0019] Preferably, it also includes a rotating disk and a fixing sleeve, with the bottom end of the battery inserted into the fixing sleeve, and the fixing sleeve mounted on the rotating disk.

[0020] When prying the nail, it is usually necessary to use a screwdriver to pry the sealing aluminum sheet from multiple directions, which requires rotating the battery multiple times. The fixing sleeve can fix the battery, and the rotating disk can drive the battery to rotate, reducing the workload of the operator.

[0021] This utility model proposes a battery cell pry bar repair auxiliary device. By aligning the relief groove with the terminal post, the clip can be quickly positioned and installed on the battery. The protective protrusion protects the terminal post, and the protective cover further protects the terminal post. The pry bar can be easily removed from the relief notch, avoiding the risk of electrostatic discharge.

[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The cover 1 has a clearance notch 6 through the middle. The fixing sleeve 9 is installed on the rotating disk 8. When prying the battery, the battery terminal end is inserted into the fixing sleeve 9, the cover 1 is fitted onto the sealed end of the battery, and the rotating disk 8 is rotated while prying the sealing aluminum sheet with a screwdriver or other tools. The prying work can be completed from multiple directions, saving the operator's physical strength and facilitating the prying work.

[0035] The cover 1 is divided into a front and a back. The back of the cover 1 is fitted onto the battery and has clearance grooves 3 on both sides. The front of the cover 1 has a protective protrusion 2. The protective protrusion 2 protrudes from the front of the cover 1. The clearance grooves 3 are aligned with the terminals, which can make way for the terminals and also allow for quick positioning, making it convenient to install the cover 1. The protective protrusion 2 increases the protection of the terminals.

[0036] Specifically, the protective protrusion 2 includes a positive terminal protection 21 and a negative terminal protection 22, and the clearance groove 3 includes a positive terminal groove 31 and a negative terminal groove 32. The positive terminal protection 21 and the positive terminal groove 31 correspond to each other, and the negative terminal protection 22 and the negative terminal groove 32 correspond to each other.

[0037] Different specifications and batches of batteries may have different lengths. To increase practicality, the cover 1 includes a positive cover 11 and a negative cover 12. The distance between the positive cover 11 and the negative cover 12 can be adjusted to accommodate batteries of different lengths. It also includes an adapter component 4 and a locking component 5. The positive cover 11 and the negative cover 12 are spliced ​​together by the adapter component 4 to form the cover 1 and locked by the locking component 5, leaving a notch 6 between the positive cover 11 and the negative cover 12.

[0038] Positive electrode post protection 21 and positive electrode post groove 31 are installed on positive electrode cover 11, and negative electrode post protection 22 and negative electrode post groove 32 are installed on negative electrode cover 12.

[0039] Preferably, both the positive terminal protection 21 and the negative terminal protection 22 are fitted with protective covers 7 on the side near the clearance notch 6. The protective covers 7 are made of metal and have impact resistance, further protecting the terminal. If the protective cover 7 is deformed, it can be directly replaced without affecting the use of the cover 1, thus reducing wear and tear costs.

[0040] Preferably, the adapter component 4 includes a slide rod 42 mounted on the positive electrode cover 11 or the negative electrode cover 12 and a slide groove 41 opened on the negative electrode cover 12 or the positive electrode cover 11. The slide groove 41 and the slide rod 42 are both on the same side as the clearance notch 6. The slide groove 41 and the slide rod 42 are slidably inserted into each other. The locking component 5 includes a fastening bolt 51.

[0041] by Figure 4For example, two sets of sliding rods 42 are installed on both sides of the positive electrode cover 11, and two sets of sliding grooves 41 are respectively opened on both sides of the negative electrode cover 12. According to the length of the battery, the relative positions of the positive electrode cover 11 and the negative electrode cover 12 are adjusted by pulling the sliding rods 42 and the sliding grooves 41. After adjusting to the appropriate position, the fastening bolts 51 pass through the negative electrode cover 12 and abut against the sliding rods 42 to fix the sliding rods 42 and the sliding grooves 41 relatively.

[0042] Preferably, the slide groove 41 is L-shaped, with the opening facing downward and inward, with the back of the cover 1 as the bottom and the clearance notch 6 as the inside. When the cover 1 is fitted onto the battery, the inner wall of the slide rod 42 is close to the outer wall of the battery.

[0043] Preferably, the slide groove 41 has a locking groove 43 along its length, and the locking groove 43 is connected to the slide groove 41. The slide rod 42 is equipped with a positioning rod 44 along its length, and the positioning rod 44 is inserted into the locking groove 43. When the cover 1 is not used, the positioning rod 44 and the locking groove 43 prevent the positive cover 11 and the negative cover 12 from being completely separated, so as to avoid the need to re-insert them when adjusting the distance.

[0044] Correspondingly, the fixing sleeve 9 includes a first insertion sleeve 91 and a second insertion sleeve 92. The first insertion sleeve 91 and the second insertion sleeve 92 are inserted into each other and fixed relative to each other by a locking member 93. A slot 81 is installed on the rotating disk 8, and the fixing sleeve 9 is snapped into the slot 81.

[0045] In summary, during maintenance, the fixing sleeve 9 is inserted into the slot 81, the distance between the first insertion sleeve 91 and the second insertion sleeve 92 is adjusted, the closed end of the battery is then inserted into the fixing sleeve 9, and the cover 1 is fitted onto the battery terminal end, so that the positive terminal is located in the positive terminal groove 31 and the negative terminal is located in the negative terminal groove 32, and the battery filling port is located within the clearance notch 6. Then the fastening bolt 51 is tightened to ensure that the cover 1 is firmly fitted onto the battery. The operator uses tools to rotate the rotating disk 8 while changing the direction of the pry pin. The cover 1 protects the side wall of the battery, and the protective protrusion 2 and the protective cover 7 protect the terminal, solving the problem of battery scrapping caused by improper operation and improving maintenance safety and reliability.
