[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0028] A preferred embodiment of the utility model is a tamper-proof wristband and a wearable device having the tamper-proof wristband; Figure 1-2 As shown, it includes a watch head 10, and wristbands arranged at both ends of the watch head, the wristbands include a long wristband 20 and a short wristband 30, the long wristband and the short wristband are respectively detachably connected to one end of the watch head, and a locking mechanism 40 is provided on the long wristband 20 and the short wristband 30, and the long wristband and the short wristband are connected and locked by the locking mechanism to facilitate wearing and taking off the wearable device.

[0029] Specifically, Figure 3As shown, the long wristband 20 and the short wristband 30 are detachably connected to the meter head 10 using the same structure, so only the connection between the short wristband and the meter head is specifically described here. The short wristband 30 includes an inner end 303 of the short wristband connected to the meter head, and a spring ear through hole 302 is provided at the inner end of the short wristband. The spring ear through hole penetrates the broken wristband in the left and right directions, and the short wristband is detachably connected to the meter head through a spring ear 50. The spring ear 50 includes a fixed portion 501 provided in the spring ear through hole 202, and a telescopic portion 500 provided in the fixed portion and passing through both sides of the fixed portion. The telescopic portion is provided inside the fixed portion, and a rotating handle 502 is provided along the vertical direction of the fixed portion 501. When the rotating handle is rotated relative to the fixed portion, the telescopic portion shrinks into the fixed portion. At this time, the short wristband and the meter head are detachable. When the short wristband with the spring ear is connected to the meter head, the rotating handle is released, and the telescopic portion extends out of the fixed portion under its own restoring force to connect with the meter head, thereby connecting and fixing the short wristband to the meter head. In order to facilitate the rotation of the rotating handle, a ball head 503 is provided at the end of the rotating handle away from the fixed part, and a switch slot 300 is provided on the short wristband 30. When the rotating handle is placed in the switch slot, the telescopic part extends out of the fixed part. When the rotating handle is turned out of the switch slot, the telescopic part contracts.

[0030] Furthermore, if Figure 2 and Figure 6-8 As shown, the locking mechanism 40 includes a fixing screw 401 connected to the short wristband 30, and a fixing screw cavity 305 is provided on the short wristband. The fixing screw is fixedly arranged in the fixing screw cavity. The fixing screw and the short wristband can also be formed in one piece. The one-piece forming arrangement makes the inner sides of the short wristband and the fixing screw flat and does not affect normal wearing. The fixing screw is provided with an inner mechanical tooth 4010, and the long wristband 20 is provided with a plurality of sets of fixing holes 201. The locking mechanism also includes a switch screw 400 passing through the fixing hole and connected to the fixing screw. The switch screw is provided with an outer mechanical tooth 4000 corresponding to the inner mechanical tooth. After the outer mechanical tooth enters the inner mechanical tooth, the switch screw and the fixing screw can be connected and locked, thereby connecting and locking the long wristband and the short wristband. Since the radius of the switch screw is larger than the radius of the fixing hole, only a specific tool can be used to disassemble the switch screw and the fixing screw at this time, thereby loosening the long wristband and the short wristband.

[0031] Furthermore, if Figure 2-6 As shown, in order to make the smart watch suitable for different people to wear, the fixing holes 201 are set in multiple groups, and the multiple groups of fixing holes are evenly distributed on the long wristband 20. The surface of the switch screw 400 is provided with a rotation groove 4001, and the switch screw can be rotated by inserting a specific tool into the rotation groove, thereby separating the switch screw from the fixing screw. The rotation groove can be set to be a straight shape, a cross shape, a plum blossom shape or other special shapes, so that it is necessary to use a specific tool to rotate the switch screw.

[0032] Furthermore, if Figure 3-6As shown, in order to improve the wearing comfort, the side of the short wristband 30 in contact with the skin is the inner side 307 of the short wristband, and the side away from the skin is the outer side 308 of the short wristband. The inner side of the short wristband is provided with an arc-shaped recess 301, so that the contact surface of the wristband with the skin is smaller when the wristband is worn, and the air permeability of the skin is increased. Multiple groups of convex strips 200 are provided on the outer side 308 of the short wristband, and the convex strips are arranged obliquely to increase the aesthetics of the wristband when worn, and the hand feel is better when touched. The inner side 202 of the long wristband is also provided with an arc-shaped recess 301, and the outer side 203 of the long wristband is also provided with a convex strip.

[0033] Furthermore, if Figure 1-6 As shown, a perforation 306 is provided on the short wristband 30, and after a part of the long wristband passes through the perforation, the outer side 203 of the part of the long wristband contacts the inner side 307 of the part of the short wristband. Due to the multiple sets of fixing holes, the distance between the fixing hole closest to the inner end 205 of the long wristband and the outer end 204 of the long wristband should be smaller than the distance from the fixing screw cavity 305 to the inner end 303 of the short wristband. At this time, the part of the long wristband passing through the perforation to the outer end of the long wristband contacts the skin, and the part of the perforation to the inner end of the short wristband contacts the skin. At this time, since the part of the long wristband is placed between the skin and the short wristband, the part is also prevented from warping.

[0034] The wearable device is suitable for special management groups, such as children, the elderly, people with dementia, people with intellectual disabilities, etc., who need to strictly wear or prevent themselves from removing the wristband. This wristband is not limited to wrist watches, but can also be used for the anti-tampering of equipment worn on the arm, the anti-tampering of equipment worn on the waist, and the anti-tampering of equipment worn on the leg, etc.

[0035] When in use, connect the short wristband 30 with the spring ear 50 to the watch head, turn the rotating handle 502 to shrink the telescopic part 500, and then release the rotating handle after the short wristband and the watch head are connected. The telescopic part can be extended to connect and lock the short wristband and the watch head. The long wristband is connected to the watch head in the same way. Then pass the outer end 204 of the long wristband through the perforation 306, select a suitable fixing hole position to align with the fixing screw, insert the switch screw into the fixing hole, and use a tool to lock the switch and the fixing screw to complete the wearing of the smart wearable device. When disassembly is required, a specific tool is inserted into the rotating slot to separate the switch screw from the fixing screw to complete the disassembly.

[0036] It should be understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
