[0021] When in use, the operator takes out the annular measuring tool 400, hangs the topmost spring coil of the spring to be measured on the positioning plate 500 for fixation, and then inserts the annular measuring tool 400 and the spring onto the measuring rod 200. When the bottommost spring coil contacts the base 100, the adjusting screw 600 is tightened to fix the position of the annular slider 300, and the spring height and the spacing between the spring coils are recorded, thereby calculating the number of coils of the spring.

[0022] Preferably, an anti-slip ring 700 is fixedly provided on the base 100, the center of the anti-slip ring 700 is the same as the center of the bottom surface of the measuring rod 200, and the diameter of the anti-slip ring 700 matches the diameter of the spring to be measured, ensuring that the spring does not slide laterally during measurement.

[0023] Preferably, a plurality of hanging grooves 800 are fixedly provided at the edge of the lower surface of the annular measuring tool 400, and the hanging grooves 800 are directed inward. When the topmost spring coil is hung on the positioning plate 500, the spring coil can be hung on the hanging grooves 800 to ensure that the spring can be stably hung on the annular measuring tool 400 without falling.

[0024] Preferably, a transmission device 110 is fixedly disposed on the base 100 , a paddle 120 is fixedly disposed on the transmission device 110 , and the transmission device 110 is used to adjust the height of the paddle 120 .

[0025] Preferably, the transmission device 110 includes a servo motor 111, a coupling 112 and a screw rod 113, the servo motor 111 and the coupling 112 are fixedly connected, the coupling 112 and the screw rod 113 are fixedly connected, and the paddle 120 is arranged on the screw rod 113 and slides up and down on the screw rod 113 in a vertical direction.

[0026] Preferably, an electronic counter 140 is fixedly provided on the side wall of the transmission device 110, and a touch sensor is provided on the paddle 120. The electronic counter 140 is connected to the touch sensor. When the paddle 120 passes through the spring coil from top to bottom, the touch sensor transmits a signal to the receiving device in the electronic counter 140, and the number displayed on the electronic counter 140 increases by one. Each time the paddle 120 is turned, the displayed number of the electronic counter 140 increases, thereby quickly calculating the number of coils of the spring, which is suitable for situations where the number of coils of the spring is relatively dense.

[0027] Preferably, a slideway 900 is provided on the side wall of the annular slider 300, and the positioning piece 500 can slide on the slideway 900 with the center point of the annular slider 300 as the center of the circle. A slot 150 is provided on the upper surface of the positioning piece 500. When fixing the spring, the uppermost spring coil is clamped in the slot 150 to fix the spring. A plurality of slots 150 are provided to adapt to and clamp springs of different diameters.

[0028] Preferably, a rotatable measuring disk 130 is fixedly provided on the base 100, the center of the measuring disk 130 is the same as the center of the bottom surface of the measuring rod 200, and the upper surface of the measuring disk 130 is marked with length scales in all directions with the center of the circle as the origin. A measuring ruler is used to continuously advance from the outside to the inside from the edge of the measuring disk 130, and the measuring disk 130 is rotated to drive the spring and the positioning plate 500 to rotate, so as to find the maximum eccentric position of the spring, and the eccentric distance of the spring is calculated according to the position of the measuring ruler on the measuring disk 130 at this time.

[0029] The working principle of this embodiment is more specifically as follows: the operator moves the annular measuring tool 400 to the outside of the measuring rod 200, hangs the spring to be measured on the annular measuring tool 400, hangs the top spring coil on the positioning piece 500 and the hanging groove 800 to fix the spring, and then inserts the annular measuring tool 400 onto the measuring rod 200. When the bottom spring coil contacts the base 100, tighten the adjusting screw 600 to fix the position of the annular slider 300. At this time, the bottom spring coil enters the anti-slip ring 700 to prevent the spring from sliding laterally. The operator starts the servo motor 111 through the control system. The servo motor 111 drives the screw rod 113 to rotate through the coupling 112. The screw rod 113 drives the paddle 120 to move. The touch sensor in the paddle 120 is connected to the electronic counter 140. When the paddle 120 passes through the spring coil from top to bottom, it is pushed once and the number displayed on the electronic counter 140 increases by one. In this way, the number of coils of the spring is quickly calculated, and the measurement of the number of coils of the spring is completed when the number of coils is relatively dense.

[0030] The mattress spring coil measuring ruler of the utility model is provided with an annular measuring tool 400 which can slide up and down on the measuring rod 200. The operator first fixes the spring on the annular measuring tool 400, and then inserts the annular measuring tool 400 into the measuring rod 200 to determine the position of the annular measuring tool 400 according to the height of the spring, records the height of the spring and the spacing of the spring coils, and then calculates the number of coils of the spring. The mattress spring coil measuring ruler can be used to quickly measure the number of coils of the spring, with small measurement error and high work efficiency.
