Description

Technical Field

[0001] This utility model belongs to the field of walkie-talkie technology, specifically a handheld explosion-proof walkie-talkie. Background Technology

[0002] A walkie-talkie is a portable two-way communication device that uses radio signals to propagate through the air to achieve instant communication between points or multiple points. It mainly consists of a casing, main unit, battery, belt clip, charging dock, and antenna. Its main feature is that it can achieve instant communication without the need for network support.

[0003] Currently, in the use of explosion-proof walkie-talkies, operators typically communicate by holding the walkie-talkie by hand. When not in use, it is clipped to the chest or waist with a belt. However, during use, the walkie-talkie is held in place by the operator's grip, and there is no other mechanism to secure it to the hand, making it prone to falling during handling. Therefore, this utility model provides a handheld explosion-proof walkie-talkie. Utility Model Content

[0004] In order to overcome the shortcomings of existing technology and solve the problem of handheld walkie-talkies being easily dropped, this utility model proposes a handheld explosion-proof walkie-talkie.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The handheld explosion-proof walkie-talkie of this utility model includes a main body, a fixed base fixedly connected to the back side of the main body, a connecting column installed on the fixed base, a strap installed on the connecting column, and a take-up roller installed inside the main body connected to the end of the strap. The take-up roller is rotatably connected to the main body, and a slot is opened at one end of the take-up roller. A plug is slidably connected in the slot, and a rotating shaft rotatably connected to the end of the plug is fixedly connected to the end of the rotating shaft. An operating block is fixedly connected to the end of the rotating shaft, and a limiting member for limiting the take-up roller is connected to the outer side of the rotating shaft, so that the walkie-talkie can be tied to the hand with the strap to prevent the walkie-talkie from falling.

[0006] As a preferred technical solution of this utility model, the limiting member includes a fixed disk fixed inside the body, a ratchet gear rotatably connected to the fixed disk, the ratchet gear being slidably connected to the rotating shaft, and a sliding groove adapted to the sliding of the ratchet gear being provided on the rotating shaft. The outer side of the ratchet gear engages with a pawl, and a rotating column rotatably connected to the fixed disk is fixedly connected to the pawl. A torsion spring fixedly connected to the fixed disk is fixedly connected to the rotating column, which facilitates limiting the rotating shaft and prevents the rotating shaft from driving the take-up roller to rotate in the opposite direction, thus avoiding the situation where the strap of the walkie-talkie becomes loose during use.

[0007] As a preferred technical solution of this utility model, a fixing plate is sleeved on the outer side of the rotating shaft and fixedly connected to the body. A spring sleeved on the outer side of the rotating shaft is fixedly connected to the fixing plate. A connecting plate fixedly connected to the end of the spring is fixedly connected to the rotating shaft, so as to facilitate the rotation shaft to reset and allow the insert block to be inserted into the slot.

[0008] As a preferred technical solution of this utility model, a positioning roller is installed on the main body near the take-up roller to facilitate the positioning of the strap and avoid excessive friction between the strap and the main body.

[0009] As a preferred technical solution of this utility model, the main body is also equipped with a belt clip, which makes it easy to clip the walkie-talkie to the chest or waist.

[0010] As a preferred technical solution of this utility model, the outer side of the operating block is provided with an anti-slip groove to improve the friction during rotation, thereby making it easier to twist the operating block.

[0011] As a preferred technical solution of this utility model, the end of the insert is tapered, which facilitates the insertion of the insert into the slot.

[0012] As a preferred technical solution of this utility model, the corners of the body are all rounded to improve the comfort of holding the walkie-talkie.

[0013] The beneficial effects of this utility model are as follows:

[0014] The handheld explosion-proof walkie-talkie of this invention features a strap that secures the walkie-talkie to the hand during use. Rotation of the operating block causes the rotating shaft to rotate, which in turn causes the take-up roller to tighten the strap. A limiting component then limits the take-up roller, ensuring the strap does not loosen during use. This solves the problem of walkie-talkies easily falling out of the hand in existing technologies.

[0015] The handheld explosion-proof walkie-talkie of this utility model has a fixing plate, a spring, and a connecting plate on the outer side of the rotating shaft. Therefore, the rotating shaft can be stably inserted into the slot, and the spring can facilitate the rotating shaft to drive the socket to reset. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Example 1:

[0025] like Figures 1 to 5 As shown, the handheld explosion-proof walkie-talkie of this utility model includes a body 1. A fixed base 2 is fixedly connected to the back side of the body 1. A connecting post 3 is installed on the fixed base 2. A strap 4 is installed on the connecting post 3. The end of the strap 4 is connected to a take-up roller 5 installed inside the body 1. The take-up roller 5 is rotatably connected to the body 1. A slot 6 is opened at one end of the take-up roller 5. An insert block 7 is slidably connected in the slot 6. A rotating shaft 8 rotatably connected to the body 1 is fixedly connected to the end of the insert block 7. An operating block 9 is fixedly connected to the end of the rotating shaft 8. A limiting member 10 for limiting the take-up roller 5 is connected to the outer side of the rotating shaft 8, so that the walkie-talkie can be tied to the hand with the strap 4 to prevent the walkie-talkie from falling.

[0026] Furthermore, the limiting member 10 includes a fixed disk 11 fixed inside the body 1. A ratchet 12 is rotatably connected to the fixed disk 11. The ratchet 12 is slidably connected to the rotating shaft 8. The rotating shaft 8 has a sliding groove 13 adapted to slide with the ratchet 12. The outer side of the ratchet 12 engages with a pawl 14. A rotating column 15 rotatably connected to the fixed disk 11 is fixedly connected to the pawl 14. A torsion spring 16 fixedly connected to the fixed disk 11 is fixedly connected to the rotating column 15. This facilitates limiting the rotating shaft 8, preventing the rotating shaft 8 from driving the take-up roller 5 to rotate in the opposite direction. Therefore, it avoids the strap 4 from becoming loose during the use of the walkie-talkie.

[0027] Furthermore, a fixing plate 17 fixedly connected to the body 1 is sleeved on the outer side of the rotating shaft 8. A spring 18 sleeved on the outer side of the rotating shaft 8 is fixedly connected to the fixing plate 17. A connecting plate 19 fixedly connected to the rotating shaft 8 is fixedly connected to the end of the spring 18, so as to facilitate the reset of the rotating shaft 8 and allow the insert 7 to be inserted into the slot 6.

[0028] Furthermore, a positioning roller 20 is installed on the main body 1 near the take-up roller 5 to facilitate the positioning of the strap 4 and avoid excessive friction between the strap 4 and the main body 1.

[0029] Furthermore, the main body 1 is also equipped with a belt clip 21, which makes it easy to clip the walkie-talkie to the chest or waist.

[0030] Furthermore, the outer surface of the operating block 9 is provided with anti-slip grooves to increase friction during rotation, thereby facilitating the turning of the operating block 9.

[0031] Furthermore, the end of the insert 7 is tapered, which facilitates the insertion of the insert 7 into the slot 6.

[0032] Furthermore, the corners of the main body 1 are all rounded to improve the comfort of holding the walkie-talkie.

[0033] Working principle: When using the walkie-talkie, first, the walkie-talkie is put on the hand using the strap 4. Then, the operating block 9 is turned. The rotation of the operating block 9 drives the rotating shaft 8 to rotate, which in turn drives the insert block 7 to rotate. The rotation of the insert block 7 causes the take-up roller 5 to rotate, and the strap 4 is wound onto the take-up roller 5. In this way, the strap 4 is tightened, so that the walkie-talkie is securely tied to the hand. During this process, the rotation of the rotating shaft 8 will drive the ratchet 12 to rotate. At this time, the rotation direction of the ratchet 12 will disengage from the pawl 14, so it will not affect the rotation of the rotating shaft 8 driving the take-up roller 5. After the strap 4 is tightened, the ratchet 12 cannot rotate in the opposite direction due to the action of the pawl 14. Therefore, the rotating shaft 8 will not rotate in the opposite direction, and the take-up roller 5 will also not rotate in the opposite direction, causing the strap 4 to loosen. Thus, during use, the strap 4 will always be in a tight state.

[0034] After use, pull the operating block 9 to move the rotating shaft 8. As the rotating shaft 8 moves, it will drive the insert 7 to move, thus moving the insert 7 away from the slot 6. At this time, the limit of the take-up roller 5 will be released, and the take-up roller 5 can rotate freely, thereby loosening the strap 4, making it easier to remove the walkie-talkie from the hand. During the movement of the rotating shaft 8, the spring 18 will be compressed. Therefore, after the strap 4 is loosened, release the operating block 9. At this time, the action of the spring 18 will cause the rotating shaft 8 to drive the insert 7 to reset, and the insert 7 will be inserted into the slot 6 again, thus facilitating the next use.
