[0003] However, the subway working environment is characterized by high personnel flow, crowded spaces, and frequent equipment vibrations. This way of carrying the communicator makes it very easy for it to fall off due to accidental collisions, crowding, or staff negligence. Once the communicator falls off, it may not only damage the equipment but also affect communication between staff, thereby interfering with the normal operation and scheduling of the subway.
[0004] To address these issues, we provide a portable wearable device for subway communication. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0029] Example 1
[0030] Please see Figures 1 to 4 This utility model is a portable wearable device for subway communication, including a mounting base 100 and a communicator 200; the back of the communicator 200 is fixedly connected to a connector 300 that is compatible with the mounting base 100, two straps 400 are installed on the back of the mounting base 100, and an anti-loss device 500 is installed on the back of the communicator 200. The straps 400 make it easy to wear the device on the body, improving the portability of the device; the anti-loss device 500 effectively prevents the communicator 200 from being lost accidentally, ensuring the safety of the device.
[0031] The mounting base 100 includes a base body 101. Both sides of the inner wall of the base body 101 are provided with insertion ports 101a. A ventilation frame 102 is fixedly connected to the back of the base body 101, and two straps 400 are fixedly connected to the back of the ventilation frame 102. The ventilation frame 102, while ensuring the structural strength of the mounting base 100, can effectively promote air circulation, avoid stuffiness caused by wearing for a long time, and improve user comfort.
[0032] The connector 300 includes a connecting plate 301 slidably connected inside the base 101. Two symmetrical sliding grooves 302 are formed on the side of the connecting plate 301 facing the communicator 200. Insert plates 303, adapted to sockets 101a, are slidably connected inside each of the two sliding grooves 302. L-shaped push plates 305 are fixedly connected to the side of each insert plate 303 facing the communicator 200. Two springs 304 are installed between the insert plates 303 and the inner walls of the sliding grooves 302. A cover plate 306 is fixedly connected between the communicator 200 and the connecting plate 301. The springs 304 push the insert plates 303 into sockets 101a, achieving a secure connection between the communicator 200 and the mounting base 100, ensuring the device will not easily detach in the complex environment of the subway. The design of the push plates 305 facilitates easy disassembly of the communicator 200 by the user, making operation simple and convenient.
[0033] Specifically, a silicone pad 103 is fixedly connected to the side of the ventilation frame 102 facing away from the communicator 200. The silicone pad 103 has evenly distributed ventilation holes that communicate with the ventilation frame 102. The silicone pad 103 is soft and conforms to human skin, reducing discomfort when wearing it. Its ventilation holes communicate with the ventilation frame 102, further enhancing the ventilation effect, keeping the wearing area dry, and improving the comfort of long-term use.
[0034] Both straps 400 are elastic silicone straps, and both straps 400 have evenly distributed ventilation holes inside. The free ends of the two straps 400 are connected by Velcro.
[0035] Furthermore, two connecting limiting holes 302a are provided on the opposite side of the two sliding grooves 302. The end of the insert plate 303 located inside the sliding groove 302 is fixedly connected to two limiting rods 303a that are movably inserted into the corresponding limiting holes 302a. The spring 304 is movably sleeved on the outside of the corresponding limiting rod 303a. The limiting rod 303a can prevent the spring 304 from bending.
[0036] The two push plates 305 are symmetrically arranged, and rubber pads 305a are fixedly connected to the opposite sides of the two push plates 305. The rubber pads 305a increase the friction of the push plate 305 surface, making the pressing operation and grip more comfortable.
[0037] The top of the communicator 200 is rotatably connected to a hanging ring 600, which provides an additional way to hang the communicator 200. Users can hang it on backpacks, belts, or other items, increasing the flexibility and versatility of carrying the device when not wearing it.
[0038] The operation process of this embodiment is as follows: When it is necessary to fix the communicator 200, the user first presses the two push plates 305 with his / her fingers. The push plates 305 drive the insert plate 303 to retract into the sliding groove 302 against the elastic force of the spring 304. Then, the connector 300 is placed into the mounting base 100. Then, the two push plates 305 are released. Then, under the action of the spring 304, the insert plate 303 is inserted into the socket 101a, thereby fixing the communicator 200 and ensuring that the device will not easily fall off in the complex vibration and crowded environment of the subway.
[0039] Example 2
[0040] Please see Figure 3 , Figure 5 and Figure 6 Based on the first specific embodiment, the anti-loss device 500 includes a mounting compartment 501 fixedly connected to the back of the communicator 200. The mounting compartment 501 is internally divided into a drive compartment 501a and a winding compartment 501b. A rotating shaft 502 is rotatably connected to the center of the mounting compartment 501. A coil spring 503 for rotating the rotating shaft 502 is installed inside the drive compartment 501a. An anti-loss rope 504 is wound around the outside of the rotating shaft 502, and the anti-loss rope 504 is located in the winding compartment 501b. Inside, one end of the anti-loss rope 504 is fixedly connected to the outside of the rotating shaft 502, and the other end of the anti-loss rope 504 extends through the inner wall of the winding chamber 501b to the outside and is fixedly connected to a T-shaped locking block 505. The top of the base 101 is fixedly connected to a locking seat 506 that matches the locking block 505. The rotating shaft 502 can be driven to rotate by the coil spring 503, so that the anti-loss rope 504 can be automatically wound, thereby preventing the anti-loss rope 504 from getting tangled.
[0041] The operation process of this embodiment is as follows: When the communicator 200 is accidentally dropped, the coil spring 503 inside the anti-loss device 500, which is in a stretched state and stores elastic potential energy, will play its role instantly. At this time, the anti-loss rope 504 bears tension due to the fall of the communicator 200 and transmits this force to the rotating shaft 502 fixedly connected to it. The coil spring 503 then converts the elastic potential energy into a restoring force, driving the rotating shaft 502 to rotate in the opposite direction, generating a rewinding force on the anti-loss rope 504. This rewinding force can not only play a buffering role and reduce the impact of the communicator 200 falling, but also, the taut anti-loss rope 504 will firmly fix the communicator 200 and restrict its range of motion, thereby effectively preventing the communicator 200 from being lost.
