Description

Technical Field

[0001] This utility model relates to the field of location positioning equipment technology, and in particular to a personal positioning device to prevent autistic children from getting lost. Background Technology

[0002] Anti-wandering personal positioning device is an electronic device that integrates satellite positioning, wireless communication and portable design. It is mainly used in the field of safety monitoring of the elderly, children and special groups, and realizes the risk of getting lost through real-time positioning and information transmission.

[0003] Typically employing a lightweight casing structure, these devices incorporate a built-in GPS / BeiDou positioning module, SIM communication module, and low-power battery. They can connect to the guardian's terminal via Bluetooth or mobile network, providing real-time feedback on the wearer's location and movement trajectory. These devices are generally worn or installed using methods such as wristbands, pendants, and clips. However, regardless of the method, when used by autistic children, due to their sensory sensitivity, the material's feel, the restrictive sensation, or even slight weight can easily cause severe discomfort. Furthermore, their strong aversion to unfamiliar objects makes it difficult for them to understand the device's protective function. Repeated disassembly and reassembly may become a habitual behavior to relieve anxiety, easily leading to device loss and directing the positioning function to fail. This prevents guardians from tracking the child's location in real time, significantly increasing the risk of getting lost or accidentally injured. Utility Model Content

[0004] The purpose of this invention is to provide a personal positioning device to prevent autistic children from getting lost, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A personal positioning device for preventing autistic children from getting lost includes a positioning device. A first wristband is fixedly connected to one side of the positioning device, and a second wristband is fixedly connected to the other side of the positioning device. A plurality of connectors are fixedly connected to the side of the first wristband away from the positioning device. A fixing sleeve is fixedly connected inside each connector. A limiting rod is inserted through the fixing sleeve. A pin is inserted between two adjacent limiting rods. A limiting buckle is rotatably connected between two connectors through the pin. A pin is rotatably connected to the pin located between two limiting rods. A limiting mechanism is provided on the limiting rod and the pin. The limiting mechanism includes a retaining sleeve. A retaining ring is inserted through the retaining sleeve. The retaining sleeve is movably connected to the limiting rod and the pin through the retaining ring.

[0007] As a further preferred embodiment of this utility model, a motherboard is fixedly connected inside the positioning device, and a display screen is fixedly connected inside the positioning device located on the motherboard. The display screen is electrically connected to the motherboard via a ribbon cable. The motherboard with an integrated communication positioning module can provide real-time positioning information to other terminals.

[0008] As a further preferred embodiment of this utility model, the second wristband has several eyelets for inserting a pin, one end of which is inserted into the corresponding eyelet to connect the first wristband and the second wristband in conjunction with the limiting buckle.

[0009] As a further preferred embodiment of this utility model, the longitudinal section of the limiting rod is polygonal, and two slots are provided on the outer side of the limiting rod. After the limiting rod with the polygonal longitudinal section is inserted and connected in the corresponding fixed sleeve, the axial movement of the limiting rod can be restricted. The slots provide positioning and limiting conditions for the connection between the retaining ring and the limiting rod.

[0010] As a further preferred embodiment of this utility model, the limiting buckle has limiting grooves on both sides with the same longitudinal cross-section as the limiting rod. One end of the limiting rod is inserted into the corresponding limiting groove, which can cooperate with the fixing sleeve to limit the axial movement of the limiting buckle. Thus, after one end of the second wristband is inserted into the limiting buckle, the limiting buckle cannot rotate, thereby limiting the separation distance between the first wristband and the second wristband. This prevents the pin from falling out of the corresponding buttonhole, and the positioning device achieves the function of preventing it from falling off through the first wristband, the second wristband, the limiting buckle, and the pin.

[0011] As a further preferred embodiment of this utility model, a first slot is provided on one side of the sleeve, and a second slot is provided on the other side of the sleeve. A sliding groove is also provided on the sleeve between the first slot and the second slot. A locking block is fixedly connected to both sides of the retaining ring, and an operating block is fixedly connected to the outside of the retaining ring. An insertion hole is provided in the operating block, and the operating block is slidably connected in the sliding groove. One side of the sleeve is inserted into the pin through the first slot, and the other side of the sleeve is inserted into the limiting rod through the second slot. The locking block is engaged in the corresponding slot. When the sleeve is inserted into the limiting rod and the pin through the first slot and the second slot, the locking blocks on both sides of the retaining ring can be engaged in the corresponding slot to achieve the engagement of the retaining ring and the limiting rod. Thus, the retaining ring is restricted between the limiting rod and the pin by the engagement of the retaining ring and the limiting rod.

[0012] As a further preferred embodiment of this utility model, an elastic support member is inserted and connected inside the sleeve. One side of the elastic support member abuts against one side of the retaining ring, and the other side of the elastic support member abuts against one side inside the sleeve. The elastic support member also includes several arc-shaped fixing rods, and an arc-shaped connecting rod is fixedly connected between two adjacent arc-shaped fixing rods. The open elastic support member composed of several arc-shaped fixing rods and arc-shaped connecting rods can provide support force to the retaining ring without affecting the assembly efficiency of the sleeve and the retaining ring, so that one end of the limiting rod can be inserted into the corresponding limiting groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the positioning device is worn on the user's wrist via a first wristband, a second wristband, a limiting buckle, and a pin. The locking groove cooperates with the limiting groove on the inner side of the limiting buckle to restrict the rotation of the limiting buckle, thereby controlling the separation distance between the first and second wristbands and preventing the pin from being pulled out of the buckle hole, which would cause the first and second wristbands to separate, thus providing an anti-tamper function. When removing the positioning device, the guardian can use pliers or other tools to insert into the two holes and push the corresponding locking ring to move, thereby pulling one end of the limiting rod out of the limiting groove, realizing the rotation of the limiting buckle. This allows one end of the pin to be pulled out of the buckle hole by pulling the second wristband, thus removing the positioning device. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-9 As shown, this utility model provides a personal positioning device for preventing autism from getting lost, including a positioning device 1. A first wristband 2 is fixedly connected to one side of the positioning device 1, and a second wristband 3 is fixedly connected to the other side of the positioning device 1. Several connectors 4 are fixedly connected to the side of the first wristband 2 away from the positioning device 1. A fixing sleeve 14 is fixedly connected inside the connector 4. A limiting rod 15 is inserted and connected inside the fixing sleeve 14. A pin 5 is inserted and connected between two adjacent limiting rods 15. A limiting buckle 6 is rotatably connected between two connectors 4 through the pin 5. A pin 7 is rotatably connected to the pin 5 located between two limiting rods 15. A limiting mechanism 8 is provided on the limiting rod 15 and the pin 5. The limiting mechanism 8 includes a retainer 9. A retaining ring 10 is inserted and connected inside the retainer 9. The retainer 9 is movably connected to the limiting rod 15 and the pin 5 through the retaining ring 10.

[0027] like Figure 2 As shown, a motherboard 11 is fixedly connected inside the locator 1, and a display screen 12 is fixedly connected inside the locator 1 on the motherboard 11. The display screen 12 is electrically connected to the motherboard 11 via a ribbon cable. The motherboard 11, which integrates a communication and positioning module, can provide real-time positioning information to other terminals.

[0028] like Figures 1-9As shown, the second wristband 3 has several eyelets 13 for inserting pins 7, one end of which is inserted into the corresponding eyelet 13 to connect the first wristband 2 and the second wristband 3 in conjunction with the limiting buckle 6. The longitudinal section of the limiting rod 15 is polygonal, and two slots 16 are provided on the outer side of the limiting rod 15. After the polygonal limiting rod 15 is inserted into the corresponding fixing sleeve 14, it can restrict the axial movement of the limiting rod 15. The slots 16 provide positioning and limiting conditions for the connection between the retaining ring 10 and the limiting rod 15. The limiting buckle 6 has limiting grooves 17 on both sides with the same longitudinal section as the limiting rod 15. One end of the limiting rod 15 is inserted into the retaining ring 10. When connected to the corresponding limiting groove 17, it can cooperate with the fixing sleeve 14 to limit the axial movement of the limiting buckle 6. This allows the limiting buckle 6 to be unable to rotate after one end of the second wristband 3 is inserted into the limiting buckle 6, thus limiting the separation distance between the first wristband 2 and the second wristband 3. This prevents the pin 7 from detaching from the corresponding buttonhole 13, thereby enabling the positioning device 1 to achieve the anti-dislodging function through the first wristband 2, the second wristband 3, the limiting buckle 6, and the pin 7. The card sleeve 9 has a first slot 18 on one side and a second slot 19 on the other side. The card sleeve 9 between the first slot 18 and the second slot 19 also has a sliding groove 26. The card ring 10 has two sides inside. Each is fixedly connected with a locking block 20. An operating block 21 is fixedly connected to the outside of the locking ring 10. The operating block 21 has an insertion hole 22 and is slidably connected within the sliding groove 26. One side of the locking sleeve 9 is inserted into the pin 5 through the first slot 18, and the other side of the locking sleeve 9 is inserted into the limiting rod 15 through the second slot 19. The locking block 20 is engaged in the corresponding slot 16. When the locking sleeve 9 is inserted into the limiting rod 15 and the pin 5 through the first slot 18 and the second slot 19, the locking blocks 20 on both sides of the locking ring 10 can be engaged with the corresponding slot 16 to achieve the locking of the locking ring 10 and the limiting rod 15. Furthermore, the locking ring 10 and the limiting rod 15... The snap-fit ​​mechanism restricts the sleeve 9 between the limiting rod 15 and the pin 5. An elastic support 23 is inserted and connected inside the sleeve 9. One side of the elastic support 23 abuts against one side of the retaining ring 10, and the other side of the elastic support 23 abuts against one side inside the sleeve 9. The elastic support 23 also includes several arc-shaped fixing rods 24. An arc-shaped connecting rod 25 is fixedly connected between two adjacent arc-shaped fixing rods 24. The open elastic support 23 composed of several arc-shaped fixing rods 24 and arc-shaped connecting rods 25 can provide support force to the retaining ring 10 without affecting the assembly efficiency of the sleeve 9 and the retaining ring 10, so that one end of the limiting rod 15 can be snapped into the corresponding limiting groove 17.

[0029] It should be noted that this utility model is a personal positioning device for preventing autistic children from getting lost. The positioning device 1 has a built-in motherboard 11, which integrates a GPS / BeiDou positioning module and a SIM communication module. It can capture the wearer's geographical location information in real time and transmit it to the guardian's terminal via mobile network or Bluetooth. At the same time, the motherboard 11 and the display screen 12 are electrically connected through a ribbon cable, which can intuitively display the working status of the device.

[0030] When worn, the first wristband 2 and the second wristband 3 wrap around the child's wrist. At this time, since the limiting grooves 17 on both sides of the limiting buckle 6 are still connected to one end of the corresponding limiting rod 15 and are in a relatively perpendicular position to the two connectors 4, one end of the pin 7 can be inserted into the corresponding buckle eye 13. Then, the two ends of tools such as snap ring pliers can be inserted into the insertion holes 22 of the corresponding operating block 21. By engaging the snap ring pliers, the two operating blocks 21 pull the two retaining rings 10 to one side in the corresponding retaining sleeve 9. At the same time, the elastic support 23 in the retaining sleeve 9 is compressed, so that the two limiting rods 15 can move in the corresponding fixing sleeve 14, and the other end of the limiting rod 15 moves from the corresponding... The buckle 6 disengages from the limiting groove 17, and the two ends of the limiting buckle 6 rotate at one end of the pin 5 and adhere to the outside of the second wristband 3. Then, the snap ring pliers are released, and the elastic support 23 applies a pushing force to the snap ring 10, so that one end of the limiting rod 15 is reinserted into the corresponding limiting groove 17, thereby limiting the rotation of the limiting buckle 6, fixing the angle of the limiting buckle 6, reducing the separation distance between the first wristband 2 and the second wristband 3, preventing the pin 7 from being pulled out of the buckle eye 13, and achieving the anti-tampering effect. When disassembling, first pull one end of the second wristband 3 to one side and bend it to expose the two clips 9. Then, as above, pull the two snap rings 10 and the limiting rod 15 with the snap ring pliers to release the rotation restriction of the limiting buckle 6.
