Description

Technical Field

[0001] The invention belongs to the technical field of data collector devices, and in particular relates to an anti-fall type data collector. Background Art

[0002] A data collector refers to a terminal device that integrates information scanning devices and data analysis and storage.

[0003] However, the existing anti-fall type data collector often has the following problems when in use:

DETAILED DESCRIPTION

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0033] like Figure 1-Figure 3 As shown, a fall-proof data collector comprises a chassis 1, a data collector 2 and a hand-held adjustment component: a closed door 3 is hinged on the top of the chassis 1; the hand-held adjustment component comprises two limit plates 4, a telescopic plate 5, a first rack plate 6, a protective outer frame 7, a rotating shaft 8, a first gear 9, a rotary motor 10 and a handle 11, the two limit plates 4 are fixedly connected to the outer wall of the chassis 1, the telescopic plate 5 is slidably connected in the two limit plates 4, the inner surfaces of the two limit plates 4 and the outer surfaces of the telescopic plates 5 are both provided with a grease layer, the first rack plate 6 is fixedly connected to the telescopic plate 5, the protective outer frame 7 is fixedly connected to the outer wall of the chassis 1, the rotating shaft 8 is rotatably connected to the side wall of the protective outer frame 7 through a bearing, the first gear 9 is fixedly connected to the middle part of the rotating shaft 8, the first gear 9 is meshed with the rack on the first rack plate 6, the rotary motor 10 is installed on the outer wall of the protective outer frame 7, the output end of the rotary motor 10 is fixedly connected to one end of the rotating shaft 8 through a coupling, and the handle 11 is fixedly connected to the end of the telescopic plate 5;

[0034] Start the rotary motor 10, and drive the rotating shaft 8 to rotate through the rotary motor 10, so that the first gear 9 on the rotating shaft 8 rotates synchronously. Since the first gear 9 is meshed with the first rack plate 6 on the telescopic plate 5, the telescopic plate 5 can be driven to move, so that the telescopic plate 5 can be telescoped and slid within the two limit plates 4, and then the lifting height of the telescopic plate 5 relative to the chassis 1 and the telescopic length of the handle 11 can be conveniently adjusted, thereby improving the suitability and convenience of the device for hand-carrying.

[0035] like Figure 1 and Figure 4 As shown, two auxiliary moving components are arranged at the bottom of the chassis 1, each of which includes two supporting sleeves 12, two supporting sleeve columns 13, two moving brackets 14, two moving rollers 15, a supporting plate 16 and a plurality of buffer springs 17. The two supporting sleeves 12 are fixedly connected to the bottom of the chassis 1, the two supporting sleeve columns 13 are respectively sealed and slidably connected in the two supporting sleeves 12, the supporting sleeves 12 are filled with compressed air, the two moving brackets 14 are respectively fixedly connected to the lower ends of the two supporting sleeve columns 13, the two moving rollers 15 are respectively rotatably connected to the two moving brackets 14 through rollers, the supporting plate 16 is fixedly connected to the lower ends of the two supporting sleeve columns 13, one end of the plurality of buffer springs 17 is fixedly connected to the supporting plate 16, and the other ends of the plurality of buffer springs 17 are fixedly connected to the bottom of the chassis 1;

[0036] When the device moves on an uneven road surface, the moving roller 15 at the bottom of the chassis 1 will cause the chassis 1 to vibrate and bump. At this time, the support sleeve 13 begins to slide in a sealed manner in the support sleeve 12. Since the support sleeve 12 is filled with compressed air, the support sleeve 13 will squeeze the compressed air when it slides in a sealed manner in the support sleeve 12. The reaction force of the compressed air can make the support sleeve 13 slide in a buffered sealed manner in the support sleeve 12, thereby reducing the degree of bumping in the movement of the device. At the same time, during the process of the support sleeve 13 retracting and moving relative to the support sleeve 12, the support sleeve 13 will drive the support plate 16 to move upward synchronously, so that the support plate 16 squeezes the buffer spring 17. The buffer spring 17 generates elastic mechanical energy due to being in a compressed state, and then the elastic mechanical energy released by the buffer spring 17 is used to further alleviate the vibration effect of the moving roller 15 on the chassis 1, thereby fully alleviating the bumpy vibration caused by the movement of the device, avoiding the device from tipping over or even falling when being carried by hand, and ensuring the stability of the data collector 2 in mobile carrying.

[0037] like Figure 5-Figure 7 As shown, a shock absorbing component is arranged inside the chassis 1, and the shock absorbing component includes two sliding rods 18, a plurality of sliding bottom blocks 19, a mounting base 20 and a plurality of compression springs 21. The two sliding rods 18 are fixedly connected to the inner wall of the chassis 1, and a plurality of sliding bottom blocks 19 are respectively slidably connected to the two sliding rods 18. The mounting base 20 is fixedly connected to the plurality of sliding bottom blocks 19. The data collector 2 is arranged in the mounting base 20. The mounting base 20 is threadedly connected with a mounting bolt 31. One end of the mounting bolt 31 is rotatably connected to a clamping plate 32, and the other end of the mounting bolt 31 is fixedly connected to a knob 33. A plurality of compression springs 21 are respectively sleeved on the two ends of the two sliding rods 18, and the two ends of each compression spring 21 are respectively fixedly connected to the end of the sliding rod 18 and the sliding bottom block 19. The shock absorbing component also includes a concave bracket 22, a second rack plate 23, two rotating brackets 24, a rotating rod 25, a second gear 26, two The threaded rod 27, two sliders 28 and two abutment brackets 29, the concave bracket 22 is fixedly connected to the bottom of the mounting base 20, the second rack plate 23 is fixedly connected to the concave bracket 22, the two rotating brackets 24 are respectively fixedly connected to the two inner side walls of the chassis 1, the rotating rod 25 is rotatably connected to the two rotating brackets 24, the second gear 26 is fixedly connected to the middle of the rotating rod 25, the second gear 26 is meshed with the rack on the second rack plate 23, the two threaded rods 27 are respectively fixedly connected to the two ends of the rotating rod 25, the two sliders 28 are respectively threadedly connected to the two threaded rods 27, the slider 28 is fixedly connected to the limited block, the inner side wall of the chassis 1 is fixedly connected to the limited rod, the limited block is provided with a through hole, the through hole matches the limited rod, the two abutment brackets 29 are respectively fixedly connected to the two sliders 28, the abutment bracket 29 and the inner side wall of the chassis 1 are provided with soft anti-skid pads 30, and the soft anti-skid pads are provided with anti-skid patterns;

[0038] When the device is subjected to vibration such as collision or falling, the mounting base 20 will start to drive the sliding bottom block 19 to move due to the influence of the vibration, so that the sliding bottom block 19 slides on the sliding rod 18. In this process, the sliding bottom block 19 will push and squeeze the compression spring 21, so that the compression spring 21 generates elastic mechanical energy and pushes the sliding bottom block 19, and then the vibration influence on the mounting base can be alleviated by the compression spring 21. At the same time, when the mounting base 20 moves, it will synchronously drive the concave bracket 22 at the bottom thereof to move, so that the second rack plate 23 on the concave bracket 22 starts to move abnormally. Since the second gear 26 on the rotating rod 25 is meshed with the second rack plate 23, the rotating rod 25 can be driven to start rotating, so that the threaded rod 27 at the end of the rotating rod 25 starts to rotate, and then one of the sliders 28 threadedly connected to the threaded rod 27 gradually approaches the inner wall of the chassis 1, so that the soft anti-skid pad 30 on the abutment bracket 29 contacts and generates friction with the soft anti-skid pad 30 on the inner wall of the chassis 1, thereby further alleviating the vibration effect on the mounting base 20, avoiding damage to the internal electronic components of the data collector 2, and ensuring the normal operation of the data collector 2.

[0039] The working principle of the present invention is as follows:

[0040] 1. When in use, if the hand-held position needs to be adjusted when the device is being transported, the rotary motor 10 can be started to drive the rotating shaft 8 to rotate, so that the first gear 9 on the rotating shaft 8 rotates synchronously. Since the first gear 9 is meshed with the first rack plate 6 on the telescopic plate 5, the telescopic plate 5 can be driven to move, so that the telescopic plate 5 can be telescopically slid in the two limit plates 4, and then the lifting height of the telescopic plate 5 relative to the chassis 1 and the telescopic length of the handle 11 can be conveniently adjusted, thereby improving the applicability and convenience of the device for hand-carrying;

[0041] 2. When the device moves on an uneven road surface, the moving roller 15 at the bottom of the chassis 1 will cause the chassis 1 to vibrate and bump. At this time, the support sleeve 13 begins to slide in a sealed manner in the support sleeve 12. Since the support sleeve 12 is filled with compressed air, the support sleeve 13 will squeeze the compressed air when sliding in a sealed manner in the support sleeve 12. The reaction force of the compressed air can make the support sleeve 13 slide in a buffered sealed manner in the support sleeve 12, thereby reducing the degree of jolting of the device. At the same time, during the process of the support sleeve 13 retracting and moving relative to the support sleeve 12, the support sleeve 13 will drive the support plate 16 to move upward synchronously, so that the support plate 16 squeezes the buffer spring 17. The buffer spring 17 generates elastic mechanical energy due to being in a compressed state, and then the elastic mechanical energy released by the buffer spring 17 further alleviates the vibration of the moving roller 15 on the chassis 1, thereby fully alleviating the jolting vibration caused by the movement of the device, avoiding the device from tipping over or even falling when being carried by hand, and ensuring the stability of the data collector 2 in mobile carrying;

[0042] 3. When the device is subjected to vibration such as collision or falling, the mounting base 20 will start to drive the sliding bottom block 19 to move due to the vibration, so that the sliding bottom block 19 slides on the sliding rod 18. During this process, the sliding bottom block 19 will push and squeeze the compression spring 21, so that the compression spring 21 generates elastic mechanical energy and pushes the sliding bottom block 19, and then the vibration effect on the mounting base can be alleviated by the compression spring 21. At the same time, when the mounting base 20 moves, it will synchronously drive the concave bracket 22 at the bottom thereof to move, so that the second rack plate 23 on the concave bracket 22 starts to move abnormally. Since the second gear 26 on the rotating rod 25 is meshed with the second rack plate 23, the rotating rod 25 can be driven to start rotating, so that the threaded rod 27 at the end of the rotating rod 25 starts to rotate, and then one of the sliders 28 threadedly connected to the threaded rod 27 gradually approaches the inner wall of the chassis 1, so that the soft anti-skid pad 30 on the abutment bracket 29 contacts and generates friction with the soft anti-skid pad 30 on the inner wall of the chassis 1, thereby further alleviating the vibration effect on the mounting base 20, avoiding damage to the internal electronic components of the data collector 2, and ensuring the normal operation of the data collector 2.
