[0005] In view of the problems existing in the above and / or existing flexible transmission devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a flexible transmission device for ear loops of medical masks. The movable wheels set at the lower end of the U-shaped plate facilitate the movement of the entire flexible transmission device, enhancing the practicality of the device. The adjusting plate and the buffer base plate can be adjusted up and down by rotating the threaded rod. When the buffer base plate is in contact with the ground, it limits the movable wheels, thereby limiting the device. When the buffer base plate is not in contact with the ground, it releases the limitation on the movable wheels, so that the device can be moved by the movable wheels. At the same time, the elastic element set up enhances the cushioning of the device.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a flexible transmission device for ear loops of medical masks. The movable wheels set at the lower end of the U-shaped plate facilitate the movement of the entire flexible transmission device, enhancing the practicality of the device. The adjusting plate and the buffer base plate can be adjusted up and down by rotating the threaded rod. When the buffer base plate is in contact with the ground, it limits the movable wheels, thereby limiting the device. When the buffer base plate is not in contact with the ground, it releases the limitation on the movable wheels, so that the device can be moved by the movable wheels. At the same time, the elastic element set in the device enhances the cushioning of the device.

[0027] Figures 1-3 The diagram shown is a structural schematic of one embodiment of a flexible ear loop transmission device for medical masks according to this utility model. Please refer to [link / reference]. Figures 1-3 The medical mask ear loop flexible transmission device of this embodiment includes a flexible transmission component 100, a support and movement component 200 and an adjustment and limiting component 300.

[0028] The flexible transmission assembly 100 includes a transmission belt 110 and a mounting frame 120 disposed outside the transmission belt 110. Preferably, in this embodiment, the top of the mounting frame 120 is slightly higher than the top of the transmission belt 110. The mounting frame 120, with its top slightly higher than the top of the transmission belt 110, acts as a barrier to prevent the ear loops of the medical mask from falling off the transmission belt 110 during transmission. A first protective pad, made of rubber, is disposed on the upper side of the inner wall of the mounting frame 120, which protects the inner wall of the mounting frame 120.

[0029] The supporting movable assembly 200 includes a plurality of U-shaped plates 210 disposed at the lower end of the mounting frame 120 and movable wheels 220 disposed at the lower end of the U-shaped plates 210. The outer walls of the U-shaped plates 210 are provided with sliding grooves 211, and a fixing plate 212 is vertically fixed on the upper side of the inner wall of the U-shaped plates 210.

[0030] The adjusting limit assembly 300 includes a threaded rod 310 vertically threaded on a fixed plate 212, an adjusting plate 320 vertically threaded at the lower end of the threaded rod 310, a horizontal plate 330 fixed at the lower end of the adjusting plate 320, an elastic element 340 at the lower end of the horizontal plate 330, and a buffer base plate 350 at the lower end of the elastic element 340. A handwheel 311 is provided at the upper end of the threaded rod 310. The adjusting plate 320 has a U-shaped cross section, and the outer wall of the adjusting plate 320 fits against the inner wall of the slide groove 211. Preferably, in this embodiment, two elastic members 340 are provided at the lower end of the horizontal plate 330. The elastic members 340 are symmetrically distributed along the vertical central axis of the horizontal plate 330. The two elastic members 340 provided at the lower end of the horizontal plate 330 further enhance the buffering performance of the entire flexible transmission device. A second protective pad is provided at the lower end of the buffer base plate 350. The second protective pad is made of rubber. The second protective pad provided at the lower end of the buffer base plate 350 plays a protective role for the buffer base plate 350, preventing the buffer base plate 350 from directly contacting the ground and causing wear.

[0031] Combination Figures 1-3The flexible transmission device for medical mask ear loops according to this embodiment is used as follows: When the device needs to be moved, the handwheel 311 is manually rotated to drive the threaded rod 310 to rotate, which in turn drives the adjusting plate 320 and the buffer base plate 350 to move upward, so that the buffer base plate 350 does not contact the ground, thereby releasing the restriction on the moving wheel 220, so that the device can be moved by the moving wheel 220. When the device moves to the designated position, the handwheel 311 is manually rotated again to drive the threaded rod 310 to rotate, which in turn drives the adjusting plate 320 and the buffer base plate 350 to move downward, so that the buffer base plate 350 contacts the ground, thereby limiting the moving wheel 220 and ensuring the stable placement of the device. At the same time, the elastic element 340 set between the horizontal plate 330 and the buffer base plate 350 enhances the cushioning of the entire flexible transmission device. During transmission, the mounting bracket 120, whose top is slightly higher than the top of the transmission belt 110, acts as a barrier to prevent the ear loops of the medical mask from falling off the transmission belt 110 during the transmission process.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
