For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0042] like Figure 1-Figure 8 As shown, an emergency call device according to an embodiment of the present invention includes:

[0043] The pager body 1, the hanging part 2, the storage shell 3, the winding part 4 and the positioning part 5.

[0044] Among them, the pager body 1 is used for communication in case of emergency;

[0045] The hanging member 2 is used to hang the pager body 1;

[0046] The storage shell 3 is used to store the hanging member 2;

[0047] The winding member 4 is used to wind up the hanging member 2;

[0048] The positioning member 5 is used to lock the winding member 4 .

[0049] like Figure 1-Figure 4 As shown, the pager body 1 includes a pager body 101 , an emergency button 102 is provided at the center of the front side of the pager body 101 , and the rear side of the pager body 101 is fixedly connected to one side of the storage shell 3 .

[0050] like Figure 1 as well as Figure 2 As shown, the front side of the pager body 101 is rotatably connected with a blocking cover 103 via a damping shaft. The blocking cover 103 can shield and protect the emergency button 102, effectively preventing the user from accidentally touching the emergency button 102 and accidentally sending out a call for help. Moreover, the setting of the damping shaft can maintain the function of fixing the torsion angle, ensuring that the blocking cover 103 does not loosen after shielding.

[0051] like Figure 3 as well as Figure 4 As shown, the hanging member 2 includes a hanging ring 201 disposed above the storage shell 3, a connecting rope 202 is movably provided on the top of the storage shell 3, and a hanging rope 203 is fixedly connected between the hanging ring 201 and the connecting rope 202. The hanging ring 201 can be used to hang the emergency call device on a wall or a bedside at home, and the hanging rope 203 can be effectively prevented from being completely stored inside the storage shell 3, so that the hanging rope 203 can be taken out from the inner cavity of the storage shell 3 later. The connecting rope 202 can be used to hang the emergency call device around the user's neck when going out, which not only prevents loss, but also facilitates the user to press the emergency button 102 in time in an emergency.

[0052] like Figure 4 As shown, there are two suspension ropes 203 , and the diameter of the suspension rope 203 is smaller than the radius of the connecting rope 202 .

[0053] like Figure 5-Figure 7 As shown, the winding member 4 includes a rope winding column 401 movably arranged on one side of the inner cavity of the storage shell 3, one end of the connecting rope 202 away from the hanging rope 203 is glued to the surface of the rope winding column 401, one end of the rope winding column 401 is fixedly connected with a baffle 402, and the other end of the rope winding column 401 is fixedly connected with a limit ring 403, and one side of the inner cavity of the storage shell 3 is provided with a limit groove 404 for the limit ring 403 to slide. The rope winding column 401 and the baffle 402 can be used to wind up the connecting rope 202 and the hanging rope 203, effectively preventing the connecting rope 202 and the hanging rope 203 from being entangled and knotted when they are stored in the inner cavity of the storage shell 3, so that the hanging rope 203 can be taken out next time.

[0054] like Figure 7 As shown, the cross-sections of the limiting ring 403 and the limiting groove 404 are both trapezoidal. The trapezoidal shape can effectively prevent the limiting ring 403 from slipping out of the inner cavity of the limiting groove 404.

[0055] like Figure 8As shown, a first groove 405 is provided at one end of the rope winding column 401 away from the baffle 402, a coil spring 406 is provided in the inner cavity of the first groove 405, a pillar 407 is inserted in the inner cavity of the coil spring 406, one end of the pillar 407 is fixedly connected to one side of the inner cavity of the storage shell 3, a second groove 408 matching with the pillar 407 is provided on one side of the inner cavity of the first groove 405, and the inner end and the outer end of the coil spring 406 are respectively fixedly connected to the outer surface of the pillar 407 and the inner wall surface of the first groove 405. The coil spring 406 can automatically return the rope winding column 401 to its original position after the rope winding column 401 is unwound once, so as to prepare for the next unwinding operation.

[0056] like Figure 8 As shown, a plurality of third grooves 409 are formed at one end of the surface of the pillar 407 and are distributed in an annular manner and at equal intervals. A ball 410 is movably embedded in the inner cavity of the third groove 409, and a slide groove 411 is formed on the inner wall of the second groove 408 for the ball 410 to roll. The third groove 409, the ball 410 and the slide groove 411 are used in coordination to reduce the friction between the second groove 408 and the pillar 407, and effectively improve the flexibility of the rope winding column 401 when rotating.

[0057] like Figure 5 , Figure 6 As shown, the positioning member 5 includes a movable plate 501 disposed on the side of the baffle 402 away from the rope winding column 401, and two symmetrical racks 502 are integrally formed on the side of the movable plate 501 facing the baffle 402, and the racks 502 are meshed with the baffle 402. A pressing block 503 is integrally formed on the side of the movable plate 501 away from the baffle 402, and one side of the pressing block 503 is movable and penetrates to the outside of the storage shell 3. The baffle 402 can be locked by the rack 502, so that the rope winding column 401 is stably maintained at a certain position, and the exposed length of the suspension rope 203 can be adjusted according to actual use requirements.

[0058] like Figure 5 , Figure 6 As shown, a hollow block 504 is fixedly connected to the surface of the rack 502, a guide rod 505 is slidably inserted into the inner cavity of the hollow block 504, both ends of the guide rod 505 are fixedly connected to the inner wall surface of the storage shell 3, a spring 506 is sleeved on the surface of the guide rod 505, and both ends of the spring 506 are respectively fixedly connected to one side of the hollow block 504 and one side of the inner cavity of the storage shell 3. The coordinated use of the hollow block 504, the guide rod 505 and the spring 506 can automatically reset the movable plate 501 and the rack 502.

[0059] like Figure 5As shown, the top of the inner cavity of the storage shell 3 is penetrated with a conduit 6 for the connecting rope 202 to pass through. The conduit 6 can guide the connecting rope 202, effectively prevent friction between the connecting rope 202, the hanging rope 203 and the baffle 402, and further extend the service life of the connecting rope 202 and the hanging rope 203.

[0060] Working principle:

[0061] 1) Wall hanging: Use the ring 201 to hang the emergency call device on the wall or bedside. By opening the cover 103, the emergency button 102 on the call device body 101 can be pressed;

[0062] 2) Use by hanging around the neck: First, hold the pager body 101 with one hand, and use the thumb to press the pressing block 503 in the direction of the winding piece 4, the pressing block 503 drives the movable plate 501, the rack 502 and the hollow block 504 to move synchronously, the hollow block 504 slides on the surface of the guide rod 505, and the spring 506 contracts under the force until the teeth of the rack 502 are disengaged from the tooth grooves of the baffle 402, and the baffle 402 can be unlocked; secondly, use the lifting ring 201 with the other hand to pull the lifting rope 203 and the connecting rope 202 upwards, so as to adjust the length of the lifting rope 203 extending out of the storage shell 3, and at the same time of unwinding, the rope column 401 drives the baffle 40 2 and the limiting ring 403 rotate synchronously, the limiting ring 403 slides in the inner cavity of the limiting groove 404, and the coil spring 406 is stretched by force. At the same time, the ball 410 rolls in the inner cavity of the slide groove 411. The user can adjust the length of the hanging rope 203 to a suitable position according to his own use needs, and then loosen the pressing block 503 and the hanging ring 201 in turn, and use the elastic restoring force of the spring 506 to finally restore the rack 502 to its original state and mesh with the baffle 402, so that the baffle 402 can be fixed, thereby locking the length of the hanging rope 203; finally, the hanging rope 203 can be used to hang the emergency call device on the user's neck.

[0063] In summary, the emergency call device, through the provision of the winding member 4, can wind up the hanging member 2 when it is not hung around the neck, effectively avoiding the phenomenon of entanglement and knotting of the hanging member 2, which not only ensures the overall simplicity of the emergency call device, but also facilitates the subsequent use of the hanging member 2, further improving the convenience of the emergency call device; through the provision of the positioning member 5, the winding member 4 can be locked, so that the winding member 4 can be stably maintained in a certain position, and then the user can adjust the exposed length of the hanging member 2 according to their own usage needs, which has the advantage of a wide range of applications. The winding member 4 can be unlocked by pressing the positioning member 5 in the opposite direction of the winding member 4, and the overall operation is simple and convenient.
