Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery production technology, and in particular to a battery terminal screwing device. Background Technology

[0002] To better utilize the internal space of the battery and achieve better sealing, some lead-acid batteries are designed with the entire busbar terminals and other lead parts immersed in sealant. After the battery is sealed, the terminals are buried in the battery cover and sealant. Before soldering the terminals, the battery cover cap needs to be removed to expose the terminals.

[0003] Currently, there are two main methods for removing battery cover caps: one is milling the terminals, which uses a dedicated milling machine, resulting in low efficiency and cumbersome operation; the other is screwing the terminals off, which involves designing the battery cover cap into a hexagonal structure with a thin, easily foldable section at the base of the cap, and then using a dedicated screwing device to unscrew it. The problem with this method is that the torque required to break the cap is too high, and the deformed cap can get stuck in the screwing device, requiring considerable force to push it out. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a battery terminal screwing device, comprising a tubular main body with a hexagonal opening at its lower end. A push rod extends through the main body from the bottom upwards, and an L-shaped ejector handle is rotatably connected to the upper end of the push rod. A return spring is sleeved on the push rod, with one end of the return spring abutting the upper end of the main body and the other end abutting the ejector handle. Two upwardly inclined rotating handles are symmetrically fixed to the side wall of the main body. Arc-shaped connecting rods are provided on both sides of the main body, with their ends rotatably connected to the main body and the ejector handle, respectively. In use, the lower end of the main body, i.e., the hexagonal opening, is fitted onto the battery cap. Then, the main body is rotated by rotating the handles to unscrew the battery cap. One hand then holds the ejector handle and presses down, causing the push rod to move downwards along the axis of the main body, pushing out the battery cap remaining in the hexagonal opening.

[0005] Both sides of the main body are equipped with arc-shaped connecting rods, and each end of the connecting rod is fitted with a pin. One end of the connecting rod is rotatably connected to the main body via the pin, and the other end of the connecting rod is rotatably connected to the bend of the ejector handle via the pin. The purpose of the connecting rods is that the ejector handle only needs to rotate around the connection between the ejector handle and the push rod to move the push rod downwards, which facilitates pushing the battery cover cap out from the bottom of the main body. The ejector handle, push rod, and connecting rods form a crank-slider mechanism, making ejection more efficient.

[0006] Preferably, a washer is provided between the return spring and the ejector handle to ensure smooth force distribution between them.

[0007] Preferably, a pin is inserted at the connection between the push rod and the ejector handle. The pin enables a rotatable connection between the two.

[0008] Preferably, one end of each pin is fitted with an anti-disengagement spring to prevent the pin from sliding axially and falling off.

[0009] Preferably, the lower part of the push rod is provided with an elongated hole that does not interfere with the pin. The elongated hole ensures that the push rod slides downward and that the pin at this location is not obstructed.

[0010] The beneficial effects of this utility model are as follows: With the help of the main body and the rotating handle, the battery cover cap can be unscrewed. Then, in conjunction with the crank-slider mechanism composed of the push rod, the ejector handle, the connecting rod and other components, the battery cover cap embedded in the regular hexagonal opening at the lower end of the main body can be easily pushed out, thereby increasing the lever arm and achieving the effect of pushing out the material with less effort.

[0013] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0014] like Figures 1 to 3As shown, a battery terminal screwing device includes a tubular body 1-1. The lower end of the body 1-1 has a regular hexagonal opening, and a circular through hole is located above the hexagonal opening with an inner diameter smaller than the diameter of the inscribed circle at the opening. A push rod 1-2 is inserted through the body 1-1 from bottom to top. The lower end of the push rod 1-2 has a larger diameter portion, preventing it from extending through the upper end of the body 1-1. A material ejection handle 1-4 is rotatably connected to the upper end of the push rod 1-2. The material ejection handle 1-4 is used for... The push rod 1-2 is L-shaped, and the ejector handle 1-4 is L-shaped. A return spring 1-6 is sleeved on the push rod 1-2 to keep the push rod 1-2 in the upper position. One end of the return spring 1-6 abuts against the upper end of the main body 1-1, and the other end abuts against the ejector handle 1-4. Two upwardly tilted rotating handles are symmetrically fixed to the side wall of the main body 1-1. Arc-shaped connecting rods 1-3 are provided on both sides of the main body 1-1, and the two ends of the connecting rods 1-3 are rotatably connected to the main body 1-1 and the ejector handle 1-4, respectively. When using the device, the hexagonal opening of the main body 1-1 is fitted onto the battery cover cap. Then, the handle is rotated to unscrew the battery cover cap. The lower end of the main body 1-1 is then aligned with the battery cover cap recycling container. The ejector handle 1-4 is pressed down, and the push rod 1-2 moves downward relative to the main body 1-1, pushing the battery cover cap out of the hexagonal opening.

[0015] A washer is provided between the return spring 1-6 and the ejector handle 1-4. The washer ensures that the return spring 1-6 is subjected to force smoothly. Furthermore, a retaining ring is provided at the upper end of the washer, and the retaining ring is engaged in a pre-set slot at the upper end of the push rod 1-2.

[0016] A pin 1-5 is inserted at the connection between the push rod 1-2 and the ejector handle 1-4.

[0017] Both sides of the main body 1-1 are provided with arc-shaped connecting rods 1-3. Pins 1-5 are inserted at both ends of the connecting rods 1-3. One end of the connecting rod 1-3 is rotatably connected to the main body 1-1 via the pins 1-5, and the other end of the connecting rod 1-3 is rotatably connected to the bend of the ejector handle 1-4 via the pins 1-5. There are a total of three pins 1-5. With the main body 1 as the fixed entity, the ejector handle 1-4, push rod 1-2, and connecting rods 1-3 form a crank-slider mechanism. At this time, only rotating the ejector handle 1-4 is needed to move the push rod 1-2 downwards.

[0018] Each of the pins 1-5 is fitted with an anti-disengagement snap ring at one end. The anti-disengagement snap ring is designed to prevent the pins 1-5 from moving axially and falling off.

[0019] The lower part of the push rod 1-2 is provided with an elongated hole that does not interfere with the pin 1-5. This ensures that the push rod 1-2 can move up and down without restriction.
