Later, a lead-acid battery capacity detection device disclosed in Chinese Patent Publication No. CN217133330U appeared, including a base, a frame arranged on the upper side of the base, a carrier plate arranged in the frame, and a control module arranged on the surface of one side of the frame. An adjustment component is arranged in the middle of the carrier plate, and the carrier plate is connected to the frame through a lifting component; the adjustment component includes a bidirectional ball screw, and the bidirectional ball screw is rotatably arranged in an adjustment port. A first nut and a second nut are symmetrically arranged on both sides of the bidirectional ball screw, a positive terminal is arranged on one side surface of the first nut, and a negative terminal is arranged on one side surface of the second nut. Positioning components are arranged on one side surfaces of the first nut and the second nut, and one end of the bidirectional ball screw is connected to the carrier plate through a transmission structure.

[0004] By adjusting the positive and negative terminal connectors on the fixed bracket, the positive and negative terminal connectors can be quickly connected to the positive and negative electrodes of the lead-acid battery by simply pressing down the fixed bracket. However, the adjustment range of the positive and negative terminal connectors of this device is limited by the length of the fixed bracket, and the scope of application is relatively small.

[0014] Beneficial Effects

[0015] The utility model provides a lead-acid battery detection device. It has the following beneficial effects:

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

An adjustable connecting device is installed at the output end of the cylinder 3, and its own structure can be adjusted according to the detected positive and negative pole positions of the lead-acid battery. After the adjustment is completed, the cylinder 3 is started, and the cylinder 3 is automatically pressed down to drive the adjustable connecting device to connect with the positive and negative poles of the lead-acid battery, and the detection result is displayed on the detector 4.

[0026] In particular, the adjustable connecting device includes an outer ring 5 movably mounted on the output end of the cylinder 3, the outer ring 5 is a circular ring structure, the side wall of the outer ring 5 is provided with a circular inner groove 6, an inner ring 7 movably mounted in the inner groove 6 and rotatable around the outer ring 5, further a second extension rod 9 is fixedly mounted on the inner ring 7, a first extension rod 8 is fixedly mounted on the outer ring 5 at a position corresponding to the second extension rod 9, a detection head 10 is movably mounted on the first extension rod 8 and the second extension rod 9, the detection head 10 is electrically connected to the detector 4, and the outer ring 5 and the inner ring 7 can rotate around the cylinder 3. The characteristics of the outer ring 5 and the inner ring 7 being rotatable around the cylinder 3 can be used to rotate at multiple angles to adapt to the different positive and negative positions of the lead-acid battery, and the side wall of the outer ring 5 crosses the inner groove 6 to connect the first extension rod 8, so that the first extension rod 8 and the second extension rod 9 can be at the same horizontal height, so that when the cylinder 3 is pressed down, the detection heads 10 on the first extension rod 8 and the second extension rod 9 can contact the positive and negative poles of the lead-acid battery together, and the structure is simple and effective.

[0027] Furthermore, in order to prevent the outer ring 5 and the inner ring 7 from shaking after being adjusted to a suitable position, a damping ring is provided between the cylinder 3 , the outer ring 5 and the inner ring 7 .

[0028] Furthermore, the top ends of the first extension rod 8 and the second extension rod 9 are both provided with a flat anti-slip sheet 11, and the detection head 10 is threadedly connected with a fastening screw 12 at the position above the anti-slip sheet 11. After the first extension rod 8 and the second extension rod 9 are rotated to the appropriate positions, the detection head 10 is moved to the appropriate position and then the fastening screw 12 is tightened to fix the position of the detection head 10.

[0029] The above embodiment is applicable to lead-acid batteries of the same size with different positive and negative pole positions. In some cases, lead-acid batteries of different sizes need to be tested. Therefore, in other embodiments, a lead-acid battery clamping device is also provided on the base 1 to clamp lead-acid batteries of different sizes to the center directly below the cylinder 3.

[0030] Specifically, the clamping device includes an adjustment groove 13 opened on the top of the base 1, the adjustment groove 13 is a cross-shaped groove, and a first bidirectional screw rod 14 and a second bidirectional screw rod 15 are vertically and staggeredly installed in the adjustment groove 13.

Both ends of the first bidirectional screw rod 14 are threadedly connected with a first clamping plate 17, and both ends of the second bidirectional screw rod 15 are threadedly connected with a second clamping plate 16. The second clamping plate 16 and the first clamping plate 17 are symmetrically arranged in the adjustment groove 13 in pairs, distributed on the four sides of the lead-acid battery in the middle of the base 1. When clamping, the first bidirectional screw rod 14 and the second bidirectional screw rod 15 are rotated, and the characteristics of the bidirectional screw rod are used to make the second clamping plate 16 and the first clamping plate 17 move closer to the middle of the base 1, so as to clamp the lead-acid battery in the center.

[0031] Furthermore, handles 18 are fixedly mounted on the ends of the first bidirectional screw rod 14 and the second bidirectional screw rod 15 for easy manipulation.

[0032] Furthermore, the cross-sectional area of ​​the bottom of the cross-shaped adjusting groove 13 is a trapezoid, and correspondingly, the bottoms of the second clamping plate 16 and the first clamping plate 17 are also matching trapezoids, so that the second clamping plate 16 and the first clamping plate 17 will not separate from the adjusting groove 13 .

[0033] The working principle of the utility model is as follows: under normal circumstances, the lead-acid battery is fixed on the base 1, and then the first extension rod 8 and the second extension rod 9 are rotated and adjusted so that the first extension rod 8 and the second extension rod 9 intersect with the positive and negative poles of the lead-acid battery, and then the position of the detection head 10 is adjusted according to the position of the positive and negative poles. After the adjustment is completed, the fastening screw 12 is tightened, and then the cylinder 3 is started. The cylinder 3 is pressed down to make the detection head 10 contact with the positive and negative poles of the lead-acid battery, so that the detector 4 tests the lead-acid battery. The rotatable first extension rod 8 and the second extension rod 9 are used to greatly expand the test adjustment range and increase the applicability. Among them, the outer ring 5 and the inner ring 7 are rotated alternately, so that the side wall of the outer ring 5 crosses the structure of the inner groove 6 connecting the first extension rod 8, so that the first extension rod 8 and the second extension rod 9 can be at the same horizontal height, so that when the cylinder 3 is pressed down, the detection heads 10 on the first extension rod 8 and the second extension rod 9 can contact the positive and negative poles of the lead-acid battery together, and the structure is simple and effective.

[0034] In special cases, the first bidirectional screw 14 and the second bidirectional screw 15 are rotated, and the second clamping plate 16 and the first clamping plate 17 are moved closer to the middle of the base 1 by utilizing the characteristics of the bidirectional screws, so as to clamp and center lead-acid batteries of different sizes.
