Description

Technical Field

[0001] This utility model relates to the field of security device technology, and in particular to a novel portable walkie-talkie. Background Technology

[0002] New portable walkie-talkies are innovative devices based on wireless communication technology, widely used in personal, home, business, and public safety applications. With technological advancements, they have not only improved in size and functionality but also integrated advanced technologies such as digital communication, multi-band support, Bluetooth and Wi-Fi connectivity, intelligent operation, and IoT integration. Digital walkie-talkies offer clearer and more stable voice communication, intelligent design enhances user experience, and Bluetooth and Wi-Fi integration expands application scenarios. Their waterproof, dustproof, and shock-resistant design ensures reliability in harsh environments, while high-efficiency batteries and fast-charging technology improve battery life. These new walkie-talkies play a vital role in public safety, outdoor exploration, and business management. In the future, with continued technological development, they will continue to meet growing communication needs and become an important component of modern communication tools.

[0003] A search revealed an existing patent (publication number: CN213094198U) disclosing a portable security device for community security, comprising a security mechanism. The security mechanism includes a walkie-talkie body, a receiving antenna connected to the top of the walkie-talkie body, a rubber pad fixedly connected to the side of the walkie-talkie body, and a protective mechanism fixedly connected to the front of the walkie-talkie body. The protective mechanism includes a sliding groove, with an isolation plate embedded inside the sliding groove. An isolation block is connected to the front of the isolation plate, and a mesh is fixedly connected to the front of the walkie-talkie body. This invention prevents droplets from entering the interior of the walkie-talkie body, thus preventing malfunctions of internal components. It also enhances the protection of the receiving antenna, resulting in more stable signal transmission and extending the lifespan of the walkie-talkie body.

[0004] However, in actual use, while the above solution secures the walkie-talkie to the body via a clip, it requires slightly lifting the clip to easily insert it inside clothing. Due to friction, a greater angle is needed to easily hang the clip on the outside of clothing. But because of this method of use, there isn't much friction between the clip and the clothing, compromising the stability of the walkie-talkie. Especially during vigorous activity or in working environments, the walkie-talkie is prone to shaking, slipping, or falling off, potentially leading to damage or loss.

[0005] Therefore, this utility model provides a novel portable walkie-talkie. Utility Model Content

[0015] Beneficial effects:

[0016] 1. The present invention provides a novel portable walkie-talkie, which converts the friction between the back clip and clothing into rotation between the rubber roller and clothing by setting a rubber roller on the back clip. This facilitates the fixation of the main unit and provides a smoother wearing experience. At the same time, the material and properties of the rubber roller itself increase the stability between the clothing and the device and reduce the risk of the device falling off.

[0017] 2. The novel portable walkie-talkie described in this utility model, by adding a folding bracket to the back clip, allows the user to simply unfold the first and second folding brackets to securely place the device on a flat surface when the main unit is inconvenient to use, thus avoiding fatigue from holding the walkie-talkie, especially when long-term calls or information viewing are required.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Reference Figure 1-7 A novel portable walkie-talkie includes a main unit 1. The main unit 1 has uniformly distributed first fixing frames 2 fixedly connected to its outer wall, supporting and fixing multiple first fixing frames 2. A rotation limiting component is provided on the outer side of each first fixing frame 2, and a back clip 24 is provided at the limiting end of the rotation limiting component. The rotation limiting component connects the first fixing frames 2 and the back clip 24. A one-way roller assembly is provided on the inner side of the back clip 24, and a rubber roller 3 is provided at the rolling end of the one-way roller assembly. The one-way roller assembly connects the back clip 24 and the rubber roller 3, allowing the rubber roller 3 to rotate only in one direction. A folding bracket assembly is provided on the outer side of the back clip 24, and a second folding frame 41 is provided at the supporting end of the folding bracket assembly.

[0030] The rotation limiting assembly includes a first connecting rod 21, which is fixedly connected to a first fixing frame 2. The first fixing frame 2 supports and fixes the first connecting rod 21. A corresponding first spring 22 is provided on the outside of the first connecting rod 21, which limits the first spring 22. A second fixing frame 23 is rotatably connected to the outside of the first connecting rod 21. One end of the first spring 22 is engaged with the outer wall of the first fixing frame 2, and the other end of the first spring 22 is engaged with the second fixing frame 23. The first fixing frame 2 limits the second fixing frame 23 with the first spring 22 as the stress point.

[0031] The unidirectional roller assembly includes a second connecting rod 31, which is fixedly connected to a rubber roller 3. The second connecting rod 31 fixes the rubber roller 3. The second connecting rod 31 is rotatably connected to a back clamp 24, which limits the second connecting rod 31. Ratchets 32 are fixedly connected to both sides of the second connecting rod 31, which simultaneously fixes the ratchet 32 ​​on both sides. Limiting teeth 35 are provided on the outer side of the ratchet 32. The limiting teeth 35 are rotatably connected to the back clamp 24. A second spring 34 is fixedly connected to the outer wall of the middle section of the limiting teeth 35. The other end of the second spring 34 is fixedly connected to a stress plate 33. The stress plate 33 is fixedly connected to the back clamp 24, which fixes the stress plate 33. At the same time, the second spring 34 pushes the limiting teeth 35 towards one side of the ratchet 32 ​​with the stress plate 33 as the stress point, limiting the ratchet 32 ​​so that the ratchet 32 ​​can only rotate in one direction.

[0032] The folding bracket assembly includes a first folding frame 4, the bottom end of which is rotatably connected to a back clip 24. The back clip 24 limits one side of the first folding frame 4. A second folding frame 41 is rotatably connected to the inner side of the first folding frame 4, limiting the second folding frame 41. A sliding groove 46 is provided on the outer side of the second folding frame 41. A limiting rod 44 is rotatably connected to the outer side of the first folding frame 4, limiting the limiting rod 44. A locking post 45 is fixedly connected to the other end of the limiting rod 44, fixing the locking post 45. The locking post 45 is slidably connected to the sliding groove 46, limiting the locking post 45 through the sliding groove 46, thereby limiting the angle of the first folding frame 4 and the second folding frame 41.

[0033] The first folding frame 4 is rotatably connected to the outside of the first limiting card 42. The first limiting card 42 is engaged with the second folding frame 41. The first folding frame 4 supports and limits the first limiting card 42, and at the same time, the first limiting card 42 engages and fixes the second folding frame 41.

[0034] The back clip 24 is rotatably connected to the second limiting clips 43 on both sides. The second limiting clips 43 are engaged with the first folding frame 4. The back clip 24 limits the second limiting clips 43 on both sides, and at the same time, the second limiting clips 43 fix the angle between the first folding frame 4 and the back clip 24.

[0035] Specifically, when using this new portable walkie-talkie: First, insert the back clip 24 into clothing. During this process, the clothing will stretch the rubber roller 3. At the same time, the back clip 24 and the second fixing bracket 23 support the first spring 22. Then, push the back clip 24 inward. During the pushing process, the rubber roller 3 will rotate. Simultaneously, the rubber roller 3 will drive the ratchet 32 ​​to rotate via the second connecting rod 31. This ratchet 32 ​​will then compress the limiting tooth 35, allowing the limiting tooth 35 to rotate outward and compress the second spring 34. At the same time, the second spring 34 will push the limiting tooth 35 towards the ratchet 32 ​​with the stress plate 33 as the stress point, thus compressing the ratchet. 32 is squeezed and limited, thereby limiting the rotation direction of ratchet 32. When the main unit 1 is inconvenient to use, it is only necessary to rotate the first limit card 42 and the second limit card 43 at the same time to cancel the locking and fixing of the second folding frame 41 and the first folding frame 4, and unfold the first folding frame 4 and the second folding frame 41. At the same time, when unfolding between the first folding frame 4 and the second folding frame 41, the sliding groove 46 on the outside of the second folding frame 41 will limit the locking post 45 and the limiting rod 44, causing the limiting rod 44 to rotate. At the same time, the sliding groove 46 will limit the angle between the second folding frame 41 and the first folding frame 4 through the limiting rod 44 and the locking post 45.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
