[0010] Further, two adaptation mechanisms are provided in the outer shell. The adaptation mechanism includes a cylinder fixedly installed on the inner wall of the top of the outer shell. The top of the cylinder extends into the hollow rubber air cushion. A plurality of air inlet holes are formed in the inner wall of the top of the cylinder.

The adaptation circular plate is slidably connected to the cylinder. A plurality of rectangular air outlet grooves are formed in the outer wall of the cylinder.

[0011] Further, a heat dissipation mechanism is provided on the outer shell. The heat dissipation mechanism includes a heat dissipation groove formed in the outer shell. A plurality of heat dissipation holes are formed in the back surface of the outer shell. A plurality of the heat dissipation holes penetrate through the heat dissipation groove. Two closing plates are slidably installed in the heat dissipation groove.

[0012] Further, transmission mechanisms are respectively provided on the two adaptation circular plates. The transmission mechanism includes a round rod fixedly installed at the bottom of the adaptation circular plate. The bottom end of the round rod extends outside the cylinder. A transmission plate is fixedly installed at the bottom end of the round rod. A limiting groove is formed in the inner wall of the back surface of the outer shell.

[0013] Further, an air inlet mechanism is provided on the front surface of the outer shell. The air inlet mechanism includes an air inlet arc tube one and an air inlet arc tube two fixedly installed on the front surface of the outer shell.

The ends of the air inlet arc tube one and the air inlet arc tube two both extend into the air suction box and communicate with the air suction box.

[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention is a purchase order storage device for a scanning device based on OCR technology. If the device falls during use, the gas in the hollow rubber air cushion will have a buffering effect on the outer shell when the device touches the ground, but the inner shell will also be affected. The storage inside the outer shell will generate a force to shake left and right, and the anti-fall spring will buffer the storage under the elastic force. If the device generates an up and down shaking force, when the storage falls, the storage will drive the two connecting plates below the storage to move away from each other, and the two connecting plates will drive the two rectangular blocks to move away from each other. Since the T-shaped air groove and the hollow rubber air cushion are connected, the T-shaped air groove also contains gas. At this time, the rectangular blocks will be affected by the gas in the T-shaped air groove when moving, generating resistance, thereby reducing the amplitude of the storage shaking, and further minimizing the damage caused by the shaking when the storage is subjected to the vibration caused by falling;

[0017] (2) The present invention is a purchase order storage device for a scanning device based on OCR technology. When the device is used, the drive motor is started, and the drive motor drives the drive rod to rotate. The drive rod drives the suction fan blades to rotate. The suction fan blades generate suction force when rotating. When the air enters the suction box, it will be discharged from two L-shaped air pipes. The gas in the L-shaped air pipe will flow into the T-shaped strip groove, and then the gas will be infused into the hollow rubber air cushion from the strip groove, so as to avoid the natural leakage of the gas in the hollow rubber air cushion when the device is not in use, resulting in the inability to produce effective buffering when the device is dropped. When the gas in the hollow rubber air cushion is sufficient, the air pressure will increase, and the gas will immediately enter the cylinder, and then the gas will push the adaptive circular plate in the cylinder to descend. When the adaptive circular plate passes through the rectangular air outlet slot, the gas will be discharged from a plurality of rectangular air outlet slots, thereby achieving the effect of releasing the gas. When the drive motor stops running, the adaptive spring will drive the adaptive circular plate to return to its position under the action of elastic force, thereby ensuring the stability of the air pressure in the hollow rubber air cushion.

[0018] (3) The present invention provides a purchase order storage device for a scanning device based on OCR technology. When the adaptable circular plate descends, the adaptable circular plate drives the round rod to descend, the round rod drives the transmission plate to descend, and the transmission plate drives the two closing plates to move away from each other. At this time, the heat dissipation slot is in an open state, and the gas discharged from the rectangular air outlet slot is discharged from the outer shell through the heat dissipation hole and the heat dissipation slot. During the gas discharge process, the heat in the outer shell is taken away to produce a heat dissipation effect. When the drive motor stops running, the closing plate is reset under the elastic force of the two adaptable springs, and the two closing plates are closed again to prevent dust from entering the outer shell from the heat dissipation slot and the heat dissipation hole when the device is not in use, affecting the normal use of the device.

[0019] (4) The purchase order storage device for a scanning device based on OCR technology according to the present invention. During the process of the cylinder sucking air, the heat dissipation holes in the second air inlet arc-shaped pipe will approach the direction of the housing under the action of air suction. At this time, the movable spring undergoes a tensile deformation. After the arc-shaped plate passes through the two connecting pipes, at this time, under the action of the air inlet hole, the second air inlet arc-shaped pipe, the connecting pipe, and the first air inlet arc-shaped pipe, the outside is communicated with the cylinder. At this time, the air suction force will draw air from the outside into the air suction box and inflate and dissipate heat for the device. After stopping the operation of the driving motor, the air suction force will disappear. At this time, under the elastic force of several movable springs, the arc-shaped plate will reset. At this time, the housing will be sealed with the outside. Since the air suction box no longer rotates, the sealing of the housing can further ensure the stability of the air pressure in the hollow rubber air cushion, thereby ensuring the protection of the memory in the housing by the hollow rubber air cushion.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 - Figure 8 As shown, the present invention is a purchase order storage device for a scanning device based on OCR technology, including an outer shell 1. An anti-fall mechanism 100 is provided on the outer shell 1. The anti-fall mechanism 100 includes hollow rubber air cushions 101 respectively fixedly installed on the top and bottom of the outer shell 1. T-shaped air grooves 102 are respectively opened on the inner walls of the top and bottom of the outer shell 1. Rectangular blocks 103 are respectively slidably installed in the two T-shaped air grooves 102. Connecting plates 104 are respectively hingedly installed on the sides of the two rectangular blocks 103 close to each other. The ends of several connecting plates 104 close to each other are hingedly installed with a C-shaped frame 105. Further included are:

[0034] Two T-shaped air grooves 102 are fixedly installed with rectangular sliding rods 106. The rectangular sliding rods 106 penetrate through the C-shaped frame 105 and are slidably connected to the C-shaped frame 105. Two rectangular long rods 107 are fixedly installed inside the C-shaped frame 105. Two fixing plates 108 are slidably sleeved on the two rectangular long rods 107. Two anti-fall springs 109 are respectively sleeved on the two rectangular long rods 107. One ends of several anti-fall springs 109 close to each other are fixedly connected to the two fixing plates 108 respectively. One ends of several anti-fall springs 109 away from each other are fixedly connected to the C-shaped frame 105. A memory 110 is fixedly installed on the front surface of the two fixing plates 108.

[0035] As Figure 3 shown, a driving mechanism 2 is arranged on the outer shell 1. The driving mechanism 2 includes a suction box 201 fixedly installed on the inner wall of the front surface of the outer shell 1. A driving motor 202 is fixedly installed on the inner wall of the front surface of the outer shell 1. A driving rod 203 is fixedly installed on the output shaft of the driving motor 202. The end of the driving rod 203 extends into the suction box 201 and is rotatably connected to the suction box 201. Several suction fan blades 204 are fixedly installed on the driving rod 203.

[0036] Start the driving motor 202. The driving motor 202 drives the driving rod 203 to rotate. The driving rod 203 will drive the suction fan blades 204 to rotate. The suction fan blades 204 will generate suction force when rotating.

[0037] As Figure 3 and Figure 5 shown, two inflation mechanisms 3 are arranged on the suction box 201. The inflation mechanism 3 includes an L-shaped air pipe 301 fixedly installed on the back surface of the suction box 201. A strip-shaped groove 302 is opened inside the outer shell 1. The bottom end of the L-shaped air pipe 301 extends into the strip-shaped groove 302. The left end and the right end of the strip-shaped groove 302 communicate with the hollow rubber air cushion 101.

[0038] When air enters the suction box 201, it will be discharged from the two L-shaped air pipes 301. The gas in the L-shaped air pipes 301 will pour into the T-shaped strip-shaped groove 302, and then the gas will be poured into the hollow rubber air cushion 101 from the strip-shaped groove 302, avoiding the natural leakage of the gas in the hollow rubber air cushion 101 when the device is not in use, resulting in ineffective buffering when the device is dropped.

[0039] As Figure 7As shown in the figure, two adaptation mechanisms 4 are arranged inside the housing 1. The adaptation mechanism 4 includes a cylinder 401 fixedly installed on the inner wall of the top of the housing 1. The top of the cylinder 401 extends into the hollow rubber air cushion 101. A number of air inlet holes 402 are opened on the inner wall of the top of the cylinder 401. An adaptation spring 403 is fixedly installed on the inner wall of the top of the cylinder 401. The bottom end of the adaptation spring 403 is fixedly installed with an adaptation circular plate 404. The adaptation circular plate 404 is slidably connected to the cylinder 401. A number of rectangular air outlet grooves 405 are opened on the outer wall of the cylinder 401.

[0040] The gas will then enter the cylinder 401, and then the gas will push the adaptation circular plate 404 inside the cylinder 401 to descend. When the adaptation circular plate 404 passes through the rectangular air outlet grooves 405, the gas will be discharged from a number of rectangular air outlet grooves 405, so as to achieve the effect of releasing gas. When the drive motor 202 stops running, the adaptation spring 403 will drive the adaptation circular plate 404 to return to its original position under the action of elastic force, so as to ensure the stable air pressure inside the hollow rubber air cushion 101.

[0041] As Figure 6 shown in the figure, a heat dissipation mechanism 5 is arranged on the housing 1. The heat dissipation mechanism 5 includes a heat dissipation groove 501 opened inside the housing 1. A number of heat dissipation holes 502 are opened on the back of the housing 1. A number of heat dissipation holes 502 all penetrate through the heat dissipation groove 501. Two closing plates 503 are slidably installed in the heat dissipation groove 501.

[0042] The gas discharged from the rectangular air outlet grooves 405 will be discharged from the heat dissipation holes 502 and the heat dissipation groove 501 outside the housing 1. During the process of gas discharge, the heat inside the housing 1 will be taken away, thus producing a heat dissipation effect. When the drive motor 202 stops running, the closing plates 503 will return to their original positions under the elastic force of the two adaptation springs 403, and the two closing plates 503 will close again, preventing dust from entering the housing 1 from the heat dissipation groove 501 and the heat dissipation holes 502 when the device is not in use, which will affect the normal use of the device.

[0043] As Figure 2 、 Figure 7 and Figure 8 shown in the figure, transmission mechanisms 6 are respectively arranged on the two adaptation circular plates 404. The transmission mechanism 6 includes a round rod 601 fixedly installed at the bottom of the adaptation circular plate 404. The bottom end of the round rod 601 extends outside the cylinder 401. The bottom end of the round rod 601 is fixedly installed with a transmission plate 602. A limit groove 603 is opened on the inner wall of the back of the housing 1. The end of the transmission plate 602 penetrates through the limit groove 603 and is fixedly connected to the closing plate 503.

[0044] When the adaptation circular plate 404 descends, the adaptation circular plate 404 will drive the round rod 601 to descend. The round rod 601 will drive the transmission plate 602 to descend. The transmission plate 602 will drive the two closing plates 503 to move away from each other. At this time, the heat dissipation groove 501 is in an open state.

[0045] As Figure 2 shown, an air inlet mechanism 7 is provided on the front surface of the outer shell 1. The air inlet mechanism 7 includes an air inlet arc tube one 701 and an air inlet arc tube two 702 fixedly installed on the front surface of the outer shell 1. A plurality of air inlet holes 703 are formed on the arc surface of the air inlet arc tube two 702.

[0046] Since the air inlet arc tube one 701 and the air inlet arc tube two 702 are in a connected state, after the air inlet arc tube two 702 is sealed, the air inlet arc tube one 701 will also be sealed, and the corresponding outer shell 1 will remain in a sealed state with the outside world.

[0047] As Figure 8 shown, a movable mechanism 8 is arranged in the air inlet arc tube two 702. The movable mechanism 8 includes a plurality of movable springs 801 fixedly installed on the inner wall of the front surface of the air inlet arc tube two 702. An arc plate 802 is fixedly installed at the ends of the plurality of movable springs 801. The arc plate 802 is adapted to the air inlet arc tube two 702. Two connecting tubes 803 are fixedly installed at the bottom of the air inlet arc tube two 702. The bottom ends of the two connecting tubes 803 are fixedly connected to and communicate with the air inlet arc tube one 701. The ends of the air inlet arc tube one 701 and the air inlet arc tube two 702 both extend into the air suction box 201 and communicate with the air suction box 201.

[0048] During the process of the cylinder 401 sucking air, the heat dissipation holes 502 in the air inlet arc tube two 702 will approach the direction of the outer shell 1 under the action of air suction. At this time, the movable springs 801 undergo tensile deformation. After the arc plate 802 passes through the two connecting tubes 803, at this time, under the action of the air inlet holes 703, the air inlet arc tube two 702, the connecting tubes 803 and the air inlet arc tube one 701, the outside world communicates with the cylinder 401. At this time, the suction force will draw air from the outside into the air suction box 201 and perform corresponding inflation and heat dissipation on the device. After stopping the operation of the driving motor 202, the suction force will disappear. At this time, under the elastic force of the plurality of movable springs 801, the arc plate 802 will reset. At this time, the outer shell 1 will remain sealed with the outside world. Since the air suction box 201 no longer rotates, the sealing of the outer shell 1 can further ensure the stability of the air pressure in the hollow rubber air cushion 101, thereby ensuring the protection of the storage device 110 in the outer shell 1 by the hollow rubber air cushion 101.

[0049] When the device drops during use, the gas in the hollow rubber air cushion 101 will buffer the outer shell 1 when the device touches the ground. However, the inside of the outer shell 1 will still be affected. The storage 110 inside the outer shell 1 will generate a left - right shaking force. The anti - fall spring 109 will buffer the storage 110 under the action of elastic force. If the device generates an up - down shaking force, when the storage 110 descends, the storage 110 will drive the two connecting plates 104 below the storage 110 to move away from each other. The two connecting plates 104 will drive the two rectangular blocks 103 to move away from each other. Since the T - shaped air groove 102 is connected to the hollow rubber air cushion 101, the T - shaped air groove 102 also contains gas. At this time, the rectangular block 103 will be affected by the gas in the T - shaped air groove 102 to generate resistance during movement, thereby reducing the shaking amplitude of the storage 110. When using the device, start the drive motor 202. The drive motor 202 drives the drive rod 203 to rotate. The drive rod 203 will drive the suction fan blade 204 to rotate. The suction fan blade 204 will generate a suction force when rotating. When the air enters the suction box 201, it will be discharged from the two L - shaped air pipes 301. The gas in the L - shaped air pipes 301 will pour into the T - shaped strip groove 302, and then the gas will be infused into the hollow rubber air cushion 101 from the strip groove 302, preventing the natural leakage of the gas in the hollow rubber air cushion 101 when the device is not in use, resulting in ineffective buffering when the device is dropped. When the gas in the hollow rubber air cushion 101 is sufficient, the air pressure will rise, and the gas will then enter the cylinder 401. Then the gas will push the adaptive circular plate 404 in the cylinder 401 to descend. When the adaptive circular plate 404 passes through the rectangular air outlet groove 405, the gas will be discharged from several rectangular air outlet grooves 405, thus achieving the effect of releasing gas. When the drive motor 202 stops running, the adaptive spring 403 will drive the adaptive circular plate 404 to return to its original position under the action of elastic force;

[0050] When the adaptive circular plate 404 descends, the adaptive circular plate 404 drives the circular rod 601 to descend, the circular rod 601 drives the transmission plate 602 to descend, and the transmission plate 602 drives the two closing plates 503 to move away from each other. At this time, the heat dissipation slots 501 are in an open state, and the gas discharged from the rectangular air outlet slot 405 will be discharged from the heat dissipation holes 502 and the heat dissipation slots 501 outside the housing 1. During the process of gas discharge, the heat inside the housing 1 will be taken away, thus producing a heat dissipation effect. When the driving motor 202 stops running, the closing plates 503 will reset under the elastic force of the two adaptive springs 403, and the two closing plates 503 will close again; during the air suction process of the cylinder 401, the heat dissipation holes 502 in the second air inlet arc-shaped pipe 702 will approach the housing 1 under the action of air suction. At this time, the movable spring 801 undergoes a tensile deformation. After the arc-shaped plate 802 passes through the two connecting pipes 803, at this time, due to the action of the air inlet hole 703, the second air inlet arc-shaped pipe 702, the connecting pipes 803 and the first air inlet arc-shaped pipe 701, the outside is communicated with the cylinder 401. At this time, the air suction force will draw air from the outside into the air suction box 201 and inflate and dissipate heat from the device. After stopping the operation of the driving motor 202, the air suction force will disappear. At this time, under the elastic force of several movable springs 801, the arc-shaped plate 802 will reset, and at this time, the housing 1 will maintain airtightness with the outside because the air suction box 201 no longer rotates.
