Abstract
Description
Technical Field
[0001] This application relates to the field of lead-acid battery technology, and in particular to a long-life, maintenance-free lead-acid battery. Background Technology
[0002] Lead-acid batteries (VRLA) are rechargeable batteries whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the discharge state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead. In the charging state, the positive and negative electrodes are mainly composed of lead sulfate. The nominal voltage of a single lead-acid battery cell is 2.0V, which can discharge to 1.5V and charge to 2.4V. In applications, six single lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery. There are also 24V, 36V, and 48V lead-acid batteries.
[0003] While existing lead-acid batteries can be used well in daily life, the stability between the connecting wires and the terminals on the battery surface is not high after the connection. This can lead to loosening of the connection, resulting in poor discharge contact, reduced battery damage, and increased frequency of lead-acid battery maintenance by staff. Utility Model Content
[0004] This application provides a long-life, maintenance-free lead-acid battery to solve the problem mentioned in the background art where the connecting wires and terminals become loose, resulting in poor discharge contact, reducing battery damage, and increasing the frequency of lead-acid battery maintenance by staff.
[0005] This application provides a long-life, maintenance-free lead-acid battery, including a battery body. A terminal post is provided on the top of the battery body, and a connecting conductive plate is inserted into the outer wall of the terminal post. An mounting block is installed on the top of the battery body, and a fixing post is fixedly connected to the outer wall of the mounting block. An adjusting post is threadedly connected to the inner wall of the fixing post, and a positioning block is rotatably connected to one end of the adjusting post. A nut is provided on the outer wall of the mounting block, and a bolt is threadedly connected to the inner wall of the nut. One end of the bolt is rotatably connected to a positioning plate rotatably connected to the inner sidewall of the mounting block, and a spring is fixedly connected to the outer wall of the positioning plate and also fixedly connected to the inner sidewall of the mounting block.
[0006] Preferably, the inner wall of the fixed column is provided with an inner spiral at the connection between it and the adjusting column, and the outer wall of the adjusting column is provided with an outer spiral that meshes with the surface of the inner spiral.
[0007] Preferably, the outer wall contour of the positioning block is U-shaped, and the lowest point of the positioning block is fitted to the highest point after the connecting conductive sheet is inserted.
[0008] Preferably, the positioning block and the connecting conductive sheet are configured in a one-to-one correspondence.
[0009] Preferably, the outer wall profile of the mounting block is U-shaped.
[0010] Preferably, a connecting groove is provided at the connection between the inner sidewall of the mounting block and the positioning plate.
[0011] Preferably, the contact area between the positioning plate and the battery body is provided with anti-slip texture, and the positioning plate is symmetrically arranged on both sides of the battery body.
[0012] Beneficial effects:
[0013] Considering that existing lead-acid batteries can be used well in daily life, the stability between the connecting wire and the terminal after connection is not high, which can cause the connecting wire to come loose. This results in poor discharge contact, reduces battery damage, and increases the frequency of lead-acid battery maintenance by staff.
[0014] This invention connects the conductive plate to the terminal block, inserts the mounting block into the battery casing, and rotates the bolt. Through the limiting action of the nut, the positioning plate slides along the inner wall of the mounting block, clamping and fixing the battery casing. Rotating the adjusting column, through the threaded connection between the adjusting column and the fixing column, causes the positioning block to extend and retract, bringing its bottom into contact with the top of the conductive plate. This presses and fixes the conductive plate, improving the stability of the connection between the battery and the conductive plate and reducing the frequency of battery maintenance.

[0030] This utility model provides, for example Figure 1-5 The diagram shows a long-life, maintenance-free lead-acid battery, comprising a battery body 1, a terminal 2 on the top of the battery body 1, a connecting conductive plate 3 inserted into the outer wall of the terminal 2, an mounting block 4 on the top of the battery body 1, a fixing post 5 fixedly connected to the outer wall of the mounting block 4, an adjusting post 6 threadedly connected to the inner wall of the fixing post 5, a positioning block 7 rotatably connected to one end of the adjusting post 6, a nut 9 on the outer wall of the mounting block 4, a bolt 10 threadedly connected to the inner wall of the nut 9, a positioning plate 11 rotatably connected to one end of the bolt 10 and rotatably connected to the inner wall of the mounting block 4, and a spring 12 fixedly connected to the outer wall of the positioning plate 11 and fixedly connected to the inner wall of the mounting block 4.
[0031] The inner wall of the fixed column 5 is provided with an inner spiral 8 at the connection between it and the adjusting column 6, and the outer wall of the adjusting column 6 is provided with an outer spiral that meshes with the surface of the inner spiral 8.
[0032] The inner spiral 8 helps to improve the stability of the positioning block 7 after its extension and retraction.
[0033] The outer wall of the positioning block 7 is U-shaped, and the lowest point of the positioning block 7 is fitted to the highest point of the connecting conductive sheet 3 after it is inserted.
[0034] The U-shaped outer contour of the positioning block 7 facilitates the stable pressing of the connecting conductive sheet 3.
[0035] The positioning block 7 and the connecting conductive sheet 3 are configured in a one-to-one correspondence.
[0036] The one-to-one correspondence between the positioning block 7 and the connecting conductive sheet 3 helps to improve the overall connection and stability of the battery.
[0037] The outer wall of mounting block 4 has a U-shaped profile.
[0038] The U-shaped outer contour of the mounting block 4 facilitates its pre-installation and use.
[0039] The inner sidewall of the mounting block 4 is provided with a connecting groove at the connection point between it and the positioning plate 11.
[0040] The opening of the connecting groove facilitates the limiting sliding of the positioning plate 11.
[0041] The positioning plate 11 has anti-slip texture at the contact area with the battery body 1, and the positioning plate 11 is symmetrically arranged on both sides of the battery body 1.
[0042] To facilitate passage, the contact area between the positioning plate 11 and the battery body 1 is provided with anti-slip texture, which improves the stability of the connection between the mounting block 4 and the battery casing.
[0043] Working principle: When using this long-life maintenance-free lead-acid battery, after connecting the conductive plate 3 to the terminal 2, the mounting block 4 is inserted into the battery casing. Rotating the bolt 10, through the limiting action of the nut 9, causes the positioning plate 11 to slide along the inner wall of the mounting block 4, so that the positioning plate 11 clamps and fixes the battery casing. Rotating the adjusting column 6, through the threaded connection between the adjusting column 6 and the fixing column 5, causes the positioning block 7 to move in a telescopic motion, so that the bottom of the positioning block 7 fits against the top of the conductive plate 3, which plays the role of pressing and fixing the conductive plate 3, improving the stability of the connection between the battery and the conductive plate, and reducing the frequency of battery maintenance by the staff.
