DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-Figure 9 The utility model provides a technical solution: a code scanning device with a mobile phone alignment structure, comprising a scanner 1 and a horizontal shock absorbing mechanism 2, a rotational shock absorbing mechanism 3 and a vertical shock absorbing mechanism 4.

The second center limiting shaft 32 is installed on the inner side of the rotary shock absorbing shell 31, the rotating disk 35 is installed on the circumferential surface of the second center limiting shaft 32, the spring 34 is installed on the upper surface of the rotating disk 35, the upper surface of the rotating disk 35 is provided with a transmission groove 36, and the transmission shaft 33 is installed on the lower surface of the horizontal shock absorbing shell 21.

[0027] The vertical shock absorbing mechanism 4 includes a vertical shock absorbing shell 41, a vertical shock absorbing spring 42 and a vertical air pressure shock absorber 43. The vertical shock absorbing shell 41 is installed at the lower end of the rotating shock absorbing shell 31. The vertical shock absorbing spring 42 is installed inside the vertical shock absorbing shell 41. The vertical air pressure shock absorber 43 is installed inside the vertical shock absorbing shell 41. This design solves the problem that the original two-dimensional code scanning and recognition device has no effective shock absorption when it is shaken violently, resulting in the scanner 1 being unable to focus quickly and having a poor experience when used.

[0028] As the first embodiment of the utility model: the No. 1 center limit shaft 24 passes through the upper surface and the lower surface of the scanning platform 22, the lower surface of the No. 1 center limit shaft 24 is fixedly connected to the horizontal shock-absorbing shell 21, a plurality of horizontal shock-absorbing springs 23 are installed on the circumferential surface of the scanning platform 22, a plurality of horizontal air pressure shock absorbers 25 are installed on the circumferential surface of the scanning platform 22, and each horizontal air pressure shock absorber 25 is installed on the inner side of the corresponding horizontal shock-absorbing spring 23, the No. 2 center limit shaft 32 is connected to the horizontal shock-absorbing shell 21 and the rotating shock-absorbing shell 31 through bearings, the No. 2 center limit shaft 32 is connected to the rotating disk 35 through bearings, the transmission shaft 33 passes through the transmission slot 36, two rotating disks 35 are installed on the circumferential surface of the No. 2 center limit shaft 32, and a spring 34 is installed on the upper surface of each rotating disk 35. One end of each spring 34 is fixedly connected to the transmission shaft 33, and the spiral directions of the two springs 34 are opposite. Six spring grooves 352 are provided on the circumferential surface of each rotating disk 35, and a block spring 353 is installed inside each spring groove 352. A block 351 is installed on the outer end surface of each block spring 353, and the block 351 is connected to the rotating disk 35 through a hinge. The blocks 351 on the two rotating disks 35 are in opposite directions. Two groups of grooves 311 are provided on the inner surface of the rotary shock-absorbing shell 31, and each group of grooves 311 are in opposite directions, respectively corresponding to the blocks 351 on the two rotating disks 35. The vertical gas pressure shock absorber 43 is installed on the inner side of the vertical shock-absorbing spring 42, and the upper surfaces of the vertical gas pressure shock absorber 43 and the vertical shock-absorbing spring 42 are fixedly connected to the lower surface of the rotary shock-absorbing shell 31.

[0029] As a second embodiment of the utility model: when the code scanning device shakes violently during use, the horizontal shock absorbing mechanism 2, the rotational shock absorbing mechanism 3 and the vertical shock absorbing mechanism 4 work respectively to keep the scanner 1 stable. The shaking of the scanner 1 drives the horizontal shock absorbing springs 23 and the horizontal air pressure shock absorbers 25 at different positions to extend and compress. The horizontal shock absorbing springs 23 will release an opposite force to the scanning platform 22 to resist the shaking force of the scanning platform 22. The horizontal air pressure shock absorber 25 can slow down the moving speed of the scanning platform 22, thereby reducing the scanning platform. When the scanner 1 rotates, the scanner 1 drives the scanning platform 22 to rotate, and the scanning platform 22 drives the transmission shaft 33 to move, so that the transmission shaft 33 moves in the transmission slot 36. When the transmission shaft 33 moves clockwise, it drives the spring 34 above to rotate, so that the spring 34 above is tightened, and the upper block 351 is stuck in the slot 311, so that the upper rotating disk 35 cannot rotate, and the transmission shaft 33 drives the lower rotating disk 35 to rotate, and at this time the spring 34 above exerts force on the transmission shaft 33. The counterclockwise rotation force reduces the scanning platform 22's tendency to rotate clockwise. When the transmission shaft 33 moves counterclockwise, it drives the spring 34 below to rotate, so that the spring 34 below is tightened, and the clamping block 351 below is clamped into the clamping slot 311, so that the rotating disk 35 below cannot rotate. The transmission shaft 33 drives the rotating disk 35 above to rotate. When the rotating disk 35 rotates, the clamping block 351 enters the spring slot 352, and the clamping block spring 353 is compressed. At this time, the spring 34 below exerts a clockwise force on the transmission shaft 33. The clockwise rotating force reduces the counterclockwise rotation tendency of the scanning platform 22, thereby reducing the self-rotation of the scanner 1. When the scanner 1 vibrates vertically, the vertical shock absorbing spring 42 and the vertical air pressure shock absorber 43 will extend or shorten at the same time, exerting opposite forces on the horizontal shock absorbing mechanism 2 and the rotary shock absorbing mechanism 3 above, so that the vertical vibration of the scanner 1 is always within a smaller shaking range and at a lower shaking speed. The shaking of the scanner 1 is reduced through the joint action of the horizontal shock absorbing mechanism 2, the rotary shock absorbing mechanism 3 and the vertical shock absorbing mechanism 4.
