[0027] A limiting ring 445 is fixed to the bottom of the outer wall of the movable rod 444, and the bottom wall of the outer shell 2 is in contact with the movable rod 444. The upward movement distance of the movable rod 444 is limited by the limiting ring 445, so that the movable plate 41 and the handle 42 are moved upward and maintain a certain distance from the bottom of the outer shell 2, so that the hand can hold the handle 42 to control the downward movement of the movable plate 41.

[0028] Please see Figure 5 The flow-limiting air valve assembly 446 includes a valve body 4461, a sealing plate 4462, an air hole 4463, a straight rod 4464, a limiting ring 4465, a compression spring 4466, a fixing rod 4467, an end cap 4468, and a filter screen 4469.

The resistance distance measuring ruler 52 is connected to the middle of the bottom end of the support plate 51. The bottom corner of the support plate 51 is fixedly connected to the top end of the limiting telescopic rod 53. The bottom ends of both the resistance distance measuring ruler 52 and the limiting telescopic rod 53 are fixedly connected to the gearbox 54. The motor 55 is installed on the right side of the gearbox 54. The output shaft of the motor 55 is connected to the transmission shaft 56. The transmission shaft 56 is located inside the gearbox 54. The bottom end of the threaded telescopic rod assembly 57 is connected to the transmission shaft 56. The top end of the threaded telescopic rod assembly 57 is fixedly connected to the support plate 51. The support plate 51 is embedded in the top wall of the base 1, and the gearbox 54 is fixed to the bottom inner side of the base 1.

[0030] The limiting telescopic rod 53 is a telescopic rod consisting of a pipe and a rod assembly. The pipe and rod are fixed to the support plate 51 and the support box 54 respectively. The limiting telescopic rod 53 is used to restrict the movement trajectory of the support plate 51 and extends and retracts in accordance with the movement of the support plate 51.

[0031] Please see Figure 8 The threaded telescopic rod assembly 57 includes a vertical rod 571, a screw 572, a worm gear 573, a worm 574, and a dustproof sleeve 575. The top end of the screw 572 extends into the vertical rod 571, and the inner wall of the vertical rod 571 is threadedly connected to the screw 572. The bottom end of the screw 572 extends into the gearbox 54 and is drivenly connected to the center of the worm gear 573. The outer wall of the worm gear 573 meshes with the worm 574. The center of the worm 574 is penetrated by a drive shaft 56, and the drive shaft 56 is drivenly connected to the worm 574. The outer wall of the vertical rod 571 is fitted with a dustproof sleeve 575, and the bottom end of the dustproof sleeve 575 is fixedly connected to the gearbox 54. The top end of the vertical rod 571 is fixedly connected to the support plate 51.

[0032] The drive shaft 56 and the screw 572 are rotatably connected to the gearbox 54 through bearings. The bearings support the drive shaft 56 and ensure its rotational accuracy.

[0033] Resistance distance measuring rulers (also known as resistance distance measuring instruments) are well-known measuring devices in this field. Their basic principle is to measure distance by measuring the linear relationship between the resistance change and the length change of a conductive material. This technology has been maturely applied in the industrial field.

[0034] In use, the height of the support plate 51 needs to be adjusted according to the height of the battery. The motor 55 is controlled to generate power to drive the transmission shaft 56 to rotate. The transmission shaft 56 drives the worm 574 to rotate. The worm 574 drives the worm wheel 573 to rotate. The worm wheel 573 drives the screw 572 to rotate. The rotation of the screw 572 drives the vertical rod 571 to slide vertically on the inner wall of the dustproof sleeve 575 through the threaded engagement between the screw 572 and the vertical rod 571. The vertical rod 571 drives the support plate 51 to move. The height of the support plate 51 is adjusted, and the displacement distance of the support plate 51 is measured by the resistance distance measuring ruler 2 52.

[0035] When measuring the height of the battery, the user holds the handle 42 and pulls it down, which moves the movable plate 41 downward. The movable plate 41 moves the conductive measuring rod of the resistance distance measuring ruler 43 downward, and at the same time moves the movable rod 444 of the elastic rod assembly 44 downward. The movable rod 444 moves the slider 442 downward. When the slider 442 moves downward, it pulls the tension spring 443 to extend. At the same time, air enters from the top of the straight tube 441. After the external air is filtered by the filter screen 4469, it pushes the sealing plate 4462. The sealing plate 4462 moves the straight rod 4464 and squeezes the compression spring 4466 to the right, so that the external air can quickly enter the interior of the straight tube 441, avoiding affecting the downward speed of the movable plate 41. The movable plate 41 is moved down until it is in contact with the top surface of the battery. The downward distance of the movable plate 41 is measured by the resistance distance measuring ruler 43. The height of the battery is calculated based on the height of the support plate 51 and the downward distance of the movable plate 41.

[0036] After the battery height measurement is completed, release the control of the handle 42. The elastic potential energy generated by the tension spring 443 pulls the slider 442 upward. The slider 442 drives the movable plate 41 upward through the movable rod 444. When the slider 442 moves upward, it squeezes the air at the top of the straight tube 441. Since the valve port of the valve body 4461 is blocked by the sealing plate 4462 at this time, the air at the top of the straight tube 441 is slowly discharged through the air hole 4463 opened in the sealing plate 4462, thereby slowing down the upward speed of the slider 442, that is, slowing down the upward speed of the movable plate 41. This prevents the movable plate 41 from moving too fast and causing equipment vibration, and avoids equipment vibration causing component failure or damage, thus ensuring the stability of the measurement process.

[0037] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0038] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
