[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-Figure 5 As shown, a detection device capable of automatically replacing disinfection paper comprises a detection body 1, a limiting mechanism 3, a reeling mechanism 4 and a pedal 2; a mounting seat 11 with a hollow interior is arranged at the bottom of the detection body 1, and the limiting mechanism 3 and the reeling mechanism 4 are both installed in the hollow part of the mounting seat 11; the reeling mechanism 4 is installed with disinfection paper, and the disinfection paper covers the detection surface of the detection body 1 from one side to the other side;

[0027] The pedal board 2 is slidably connected to the mounting seat 11 and is connected to the limiting mechanism 3. The pedal board 2 is located between the detection surface of the detection body 1 and the disinfection paper. When the pedal board 2 slides toward the bottom of the mounting seat 11, the limiting mechanism 3 and the winding mechanism 4 are driven to idle. When the pedal board 2 slides toward the top of the mounting seat 11, the winding mechanism 4 and the limiting mechanism 3 are driven to rotate synchronously. When the winding mechanism 4 and the limiting mechanism 3 rotate synchronously, the disinfection paper located on the detection surface of the detection body 1 is wound up.

[0028] When the user steps on the pedal 2, the pedal 2 will slide to the bottom of the mounting seat 11, and at the same time drive the limit mechanism 3 to work and enter the idling state, that is, when the user stands on the pedal 2 to perform weight detection, the reeling mechanism 4 will not actively reel the disinfection paper, thereby avoiding the accuracy of the detection result being affected by the movement of the disinfection paper during the detection process; when the user completes the weight detection and leaves the pedal 2, the pedal 2 automatically slides to the top of the mounting seat 11 due to the loss of pressure, and this resetting process drives the limit mechanism 3 and the reeling mechanism 4 to resynchronize. At this time, the reeling mechanism 4 starts to work, rolls up and collects the old disinfection paper covering the detection surface of the detection body 1, and releases new disinfection paper to cover the detection surface, ready for the next use: the new disinfection paper is automatically replaced after each detection, effectively avoiding the risk of cross infection and ensuring the health and safety of each user; the automatic paper replacement process is fast and does not require manual intervention, which simplifies the process of replacing disinfection paper, reduces waiting time, and improves the overall use efficiency of the detection equipment. The user only needs to step on the pedal 2 to complete the detection and paper replacement process, which is simple and fast to operate.

[0029] In one embodiment, the limiting mechanism 3 includes a transmission component 31 and a limiting component 32; the transmission component 31 is rotatably mounted on the mounting seat 11, the transmission component 31 is connected to the pedal board 2, when the pedal board 2 moves, the transmission component 31 rotates, the transmission component 31 and the limiting component 32 are limitedly abutted, the limiting component 32 is fixedly mounted on the winding mechanism 4, when the transmission component 31 rotates in the opposite direction, it abuts against the limiting component 32 and drives the limiting component 32 to rotate, when the limiting component 32 rotates, it drives the winding mechanism 4 to rotate and rewind the disinfection paper; when the user steps on the pedal board 2, the pedal board 2 will slide to the bottom of the mounting seat 11, so that the transmission component 31 starts to rotate, when the transmission component 31 rotates, It will form a limiting abutment with the limiting component 32. In the initial stage when the pedal 2 slides to the bottom, this abutment relationship makes the limiting component 32 remain stationary, while the transmission component 31 idles, thereby avoiding the erroneous action of the winding mechanism 4 to also wind up the disinfectant paper when the human body is detecting weight; when the user completes the weight detection and leaves the pedal 2, the pedal 2 will automatically slide to the top of the mounting seat 11 to reset. During the resetting process, the transmission component 31 rotates in the opposite direction. At this time, due to the change in the rotation direction of the transmission component 31, the limiting component 32 is driven to start rotating, and the rotational force is transmitted to the winding mechanism 4, thereby winding up the used disinfectant paper and re-spreading new disinfectant paper.

[0030] In one embodiment, the transmission assembly 31 includes a vertical screw 311, a first bevel gear 312, and a second bevel gear 313; the vertical screw 311 is rotatably mounted on the mounting seat 11, the pedal 2 is threadedly connected to the vertical screw 311, the first bevel gear 312 is fixedly mounted on the upper part of the vertical screw 311, the second bevel gear 313 and the first bevel gear 312 are meshed to change the horizontal rotation direction to the vertical rotation direction; the pedal 2 is tightly connected to the vertical screw 311 through a threaded hole, and when the user steps on the pedal 2, the pedal 2 will move downward along the vertical screw 311. Due to the constraint of the thread, the movement of the pedal 2 will drive the vertical screw 311 to rotate. Since the first bevel gear 312 is fixedly installed on the upper part of the vertical screw 311, when the vertical screw 311 rotates, the first bevel gear 312 will also rotate synchronously. This design ensures that the vertical movement of the pedal 2 can be converted into the horizontal rotation of the first bevel gear 312. The first bevel gear 312 and the second bevel gear 313 are meshed with each other to form a pair of bevel gear transmission pairs, and the horizontal rotation of the first bevel gear 312 is converted into the vertical rotation of the second bevel gear 313. When the second bevel gear 313 rotates, it will drive the winding mechanism 4 to start working, so as to realize the winding and replacement of the disinfection paper.

[0031] In one embodiment, the limiting assembly 32 includes a connecting block 321, a spring block 322 and a clamping block 323. The connecting block 321 is provided with at least two mounting grooves 3211 toward the center of the circle. Any mounting groove 3211 is rotatably connected to the spring block 322 and the clamping block 323. The rotation points of the spring block 322 and the clamping block 323 are respectively located at the ends of the installing groove 3211. The other end of the spring block 322 abuts against the clamping block 323 from the inner side of the clamping block 323. A ratchet 5 is provided inside the second bevel gear 313. The second bevel gear 313 is coaxially arranged with the connecting block 321. The ratchet 5 is located at the outer periphery of the connecting block 321. The end of the clamping block 323 away from the rotation point is a clamping surface. When the second bevel gear 313 rotates in the opposite direction, it abuts against the clamping surface to drive the connecting block 323. The connecting block 321 rotates synchronously with the second bevel gear 313; when the engaging surface of the block 323 does not contact the ratchet teeth 5 of the second bevel gear 313, the connecting block 321 and the second bevel gear 313 are in a relatively free state; when the second bevel gear 313 rotates in the positive direction, its ratchet teeth 5 will slide over the engaging surface of the block 323 in sequence without causing any hindrance, because at this time the abutment force of the spring block 322 on the block 323 is not sufficient to cause the block 323 to rotate in the opposite direction to engage the ratchet teeth 5; therefore, in this direction, the second bevel gear 313 can rotate freely, while the winding mechanism 4 connected to the connecting block 321 remains stationary; however, when the second bevel gear 313 rotates in the opposite direction, the ratchet teeth 5 will try to push the engaging surface of the block 323. Due to the relative position of the ratchet 5 and the engaging surface at this time, the clamping block 323 can overcome the preload force and rotate with the assistance of the spring block 322, thereby engaging the ratchet 5. Once the clamping block 323 engages with the ratchet 5, the reverse rotation of the second bevel tooth 313 is transmitted to the connecting block 321 through the clamping block 323, so that the connecting block 321 rotates synchronously with the second bevel tooth 313, and drives the winding mechanism 4 to rotate and wind together.

[0032] In one embodiment, the pitch of the vertical screw 311 is at least 30 mm, and the tooth number ratio of the first bevel gear 312 and the second bevel gear 313 is 2:1, so that when the pedal 2 moves from the top to the bottom of the mounting base 11, the vertical screw 311 rotates at least one circle, and when the vertical screw 311 rotates one circle, it also drives the first bevel gear 312 to rotate one circle. Since the tooth number ratio of the first bevel gear 312 and the second bevel gear 313 is 2:1, when the first bevel gear 312 rotates one circle, the second bevel gear 313 rotates two axes, that is, the second bevel gear 313 drives the active roller 41 to rotate two circles. At this time, the ratio of the width of the detection surface to the circumference of the active roller 41 is set to 1:2, then the active roller 41 rotates 2 circles just to completely reel up the used disinfection paper, and at the same time, it can also reduce the space occupied by the mounting base 11.

[0033] In one embodiment, it also includes a reset member 6. The detection surface of the detection body 1 is provided with a sliding groove 12. When detecting the weight, the pedal 2 is moved to the sliding groove 12. The reset member 6 is installed in the sliding groove 12. When there is no gravity on the detection surface, the pedal 2 is automatically reset to the top of the mounting seat 11; the reset member 6 includes a support column 61 and a spring 62. The support column 61 is fixedly installed on the mounting seat 11 and extends to the sliding groove 12, which is used to transmit the force of the spring 62 when it is compressed to the mounting seat 11; one end of the spring 62 is fixed to the support column 61, and the other end is fixedly connected to the bottom of the pedal 2; the spring 62 is in a compressed state when it bears the weight of the pedal 2 and the person being detected, but this compression The state does not change the overall balance of the detection surface. The detection surface is mainly used to detect the weight of the human body. When the person being detected stands on the pedal 2, the pedal 2 transmits the force to the mounting seat 11 instead of the detection surface. In this process, although the spring 62 is compressed, the elastic force of the spring 62 does not directly act on the detection surface and will not have a direct impact on the detected weight. The existence of the spring 62 enables the pedal 2 to automatically reset to the top of the mounting seat 11 when there is no gravity on the detection surface. No manual operation is required, thereby improving the convenience and efficiency of use. The elastic force of the spring 62 does not directly act on the detection surface and therefore will not have a direct impact on the detected weight, thereby ensuring the accuracy of the detection.

[0034] In one embodiment, the height of the mounting base 11 is higher than the height of the detection surface of the detection body 1. The increased height of the mounting base 11 allows the pedal 2 to have a larger space during movement and resetting, and is also beneficial for the spreading and rolling of the disinfection paper, ensuring that the disinfection paper can be located on the detection surface and the top of the pedal 2.

[0035] In one embodiment, the winding mechanism 4 includes an active roller 41 and a passive roller 42; the active roller 41 and the passive roller 42 are both rotatably mounted on the mounting seat 11, one end of the disinfection paper is wound on the active roller 41, and the other end is wound on the passive roller 42; the connecting block 321 is fixedly mounted on the active roller 41, the ratchet 5 and the card block 323 are limitedly abutted and drive the active roller 41 to rotate, and the active roller 41 rotates to wind up the disinfection paper located on the detection surface; one end of the disinfection paper is wound on the active roller 41, and the other end is wound on the passive roller 42. The active roller 41 and the passive roller 42 are both mounted on the mounting base 11 through bearings or other rotating devices to ensure that they can rotate freely. The connecting block 321 is fixedly mounted on the active roller 41 to transmit external power or torque. After a single weight test is completed, the pedal 2 loses the effect of gravity, causing the limit mechanism 3 to rotate in the opposite direction, thereby driving the active roller 41 to rotate and rewind the used disinfection paper. As the rewinding proceeds, the passive roller 42 also rotates to re-spread the new disinfection paper on the test surface and restart the test.

Although the present invention has been disclosed as above in the form of preferred embodiments, it is not intended to limit the present invention. Any technical personnel in the field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
