Specific embodiments

[0021] To make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0022] Please refer to Figures 1 to 5 , the embodiment of the present application provides a mobile police intelligent terminal, including a body 1 and a cover body 2 detachably installed on the back of the body 1. The body 1 is the main body of the mobile police intelligent terminal, and the cover body 2 is detachably connected to the body 1 by screws 5; a winding mechanism 3 and a releasing mechanism 4 are provided inside the cover body 2;

[0023] The winding mechanism 3 includes a winding shaft 31, a driving shaft 32, a first gear 33, a second gear 34, a coil spring 35, and a hanging rope 36. The winding shaft 31 and the driving shaft 32 are both rotatably installed on the body 1. Both ends of the hanging rope 36 are wound in the same direction on the winding shaft 31. A first opening 21 for the hanging rope 36 to extend out is provided on the cover body 2. One end of the coil spring 35 is fixedly connected to the body 1, and the other end of the coil spring 35 is fixedly connected to the driving shaft 32. The first gear 33 is fixedly installed on the winding shaft 31, the second gear 34 is fixedly installed on the driving shaft 32, and the first gear 33 is meshed with the second gear 34;

[0024] The release mechanism 4 includes a clamping plate 41, a button 42, a guiding square rod 43, a guiding square cylinder 44, and a compression spring 45. The guiding square cylinder 44 is fixedly installed on the machine body 1. One end of the guiding square rod 43 is slidably inserted into the guiding square cylinder 44. The other end of the guiding square rod 43 is fixed with the button 42. One end of the button 42 away from the guiding square rod 43 extends out of the cover body 2. The clamping plate 41 is fixedly installed on the guiding square rod 43. The clamping plate 41 can move along a direction parallel to the axis direction of the driving shaft 32. One end of the clamping plate 41 has a clamping tooth 411 engaged with the second gear 34. One end of the compression spring 45 is connected to the machine body 1, and the other end is connected to the clamping plate 41. The guiding square rod 43 and the guiding square cylinder 44 play a guiding role for the clamping plate 41, so that when the button 42 is pressed, the button 42 drives the guiding square rod 43 and the clamping plate 41 to move linearly along a direction parallel to the axis direction of the driving shaft 32, thereby separating the clamping tooth 411 from the second gear 34.

[0025] To facilitate pressing the button 42, a second opening 22 is provided on the cover body 2. The button 42 includes a pressing part 421 and a limiting part 422. The pressing part 421 and the limiting part 422 are fixedly connected. The size of the pressing part 421 is smaller than the size of the second opening 22. The pressing part 421 passes through the second opening 22. The size of the limiting part 422 is larger than the size of the second opening 22. The second opening 22 restricts the passing of the limiting part 422. Under the elastic force of the compression spring 45, a thrust can be provided to the clamping plate 41, the guiding square rod 43, and the button 42, so that the limiting part 422 abuts against the second opening 22. At this time, the clamping tooth 411 is engaged with the second gear 34; when the button 42 is pressed and one end of the pressing part 421 away from the limiting part 422 is pressed into the second opening 22, the clamping tooth 411 is separated from the second gear 34.

[0026] To facilitate the installation of the torsion spring 35, one end of the torsion spring 35 is connected to the machine body 1. An installation seat 37 is fixedly installed on the machine body 1. The installation seat 37 is cylindrical. The torsion spring 35 is located inside the installation seat 37. One end of the torsion spring 35 is fixedly connected to the installation seat 37, and the other end is fixedly connected to the driving shaft 32.

[0027] To facilitate the rotational installation of the winding shaft 31 and the driving shaft 32 on the machine body 1, a first bearing 38 and a second bearing 39 are installed on the back of the machine body 1. The winding shaft 31 is rotationally connected to the machine body 1 through the first bearing 38, and the driving shaft 32 is rotationally connected to the machine body 1 through the second bearing 39.

[0028] To facilitate wearing the hanging rope 36, the winding shaft 31 is arranged above the driving shaft 32. To facilitate the installation of the button 42, the release mechanism 4 is arranged below the driving shaft 32.

[0029] Working principle: By pressing the button 42 with the thumb, the clamping tooth 411 is separated from the second gear 34, as Figure 4As shown; at the same time, hold the body 1 with other fingers, so that when wearing the lanyard 36, the body 1 can be firmly held. After holding the body 1 tightly, under the action of the elastic restoring force of the coil spring 35, there will be a tendency to wind up the lanyard 36;

[0030] Quickly move the body 1 by holding the body 1, so that the body 1 is away from the human body wearing place. The winding shaft 31 is stressed to unwind the lanyard 36, and the length of the lanyard 36 can be quickly adjusted. The winding shaft 31 drives the second gear 34 and the drive shaft 32 to rotate through the first gear 33, and then drives the coil spring 35 to move, and the coil spring 35 stores elastic energy;

[0031] After the length of the lanyard 36 is adjusted, release the button 42. Under the action of the elastic restoring force of the compression spring 45, the compression spring 45 pushes the clamping plate 41 to reset, so that the clamping teeth 411 are engaged with or abutted against the second gear 34. At the same time, under the action of the elastic restoring force of the coil spring 35, the drive shaft 32 and the second gear 34 will be driven to rotate. When the second gear 34 rotates to the angle where it is engaged with the clamping teeth 411, the clamping teeth 411 are re-engaged with the second gear 34 under the thrust of the compression spring 45, restricting the rotation of the second gear 34; at this time, the unwinding length of the lanyard 36 is longer, which is convenient for using the police intelligent terminal;

[0032] After the police intelligent terminal is used up, press the button 42 again, hold the body 1 and move it closer to the human body wearing place. Under the action of the elastic restoring force of the coil spring 35, the drive shaft 32 and the winding shaft 31 are driven to rotate, and the winding shaft 31 automatically winds up the lanyard 36; after the lanyard 36 is adjusted to an appropriate length, release the button 42, and the clamping teeth 411 are engaged with the second gear 34 again, restricting the rotation of the winding shaft 31, and the length of the lanyard 36 can be quickly adjusted, which is convenient to use.

[0033] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
