Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to an adjustable fingerprint input device based on the Internet of Things. Background Art

[0002] The Internet of Things is a network based on information carriers such as the Internet and traditional telecommunications networks, which enables all ordinary objects that can perform independent functions to be interconnected. Its application areas mainly include transportation and logistics, industrial manufacturing, health care, smart environment (home, office, factory), etc., and it has a very broad market prospect.

[0003] When employees go to work, they need to clock in through a time clock machine, enter their fingerprints into the time clock machine, and upload the data to the Internet through the time clock machine for collection. However, when entering the fingerprint, once the fingerprint and the recording plate generate an intersecting force, the fingerprint will be deformed on the surface of the recording plate, making it difficult to identify and need to be entered again, which reduces the efficiency of clocking in and wastes employee time. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides an adjustable fingerprint input device based on the Internet of Things, which has the advantages of automatically adjusting the angle of the fingerprint entry plate when the fingerprint and the fingerprint entry plate generate an interlaced force, so that the fingerprint is no longer deformed and it is easy to enter successfully. This solves the problem that the existing fingerprint entry device cannot automatically adjust the angle of the fingerprint entry plate when the fingerprint and the fingerprint entry plate generate an interlaced force, so that the fingerprint is deformed and it is difficult to enter successfully.

[0006] (II) Technical solution

[0007] In order to achieve the purpose of automatically adjusting the angle of the fingerprint entry plate when the fingerprint and the fingerprint entry plate generate an interlaced force, so that the fingerprint is no longer deformed and is easy to enter successfully, the present invention provides the following technical solution: an adjustable fingerprint input device based on the Internet of Things, comprising a shell, a recording plate is inserted on the top of the shell, a pressing spring is fixedly connected to the bottom of the recording plate, an adjusting air box is fixedly connected to the inner bottom wall of the shell, a receiving plate is slidably connected to the inside of the adjusting air box, a receiving plate is fixedly connected to the top of the receiving plate, a receiving rod is meshedly connected to the side of the receiving rod, a vibration wheel is rotatably connected to the top of the receiving wheel through a belt, a support rod is fixedly connected to the side of the recording plate, a pressing rod is slidably connected to the bottom of the support rod, a connecting rod is fixedly connected to the side of the pressing rod, a connecting rod is fixedly connected to the top of the connecting rod, a suction plate is fixedly connected to the top of the connecting rod, a suction box is slidably connected to the side of the suction box, an air spring is fixedly connected to the top of the suction box through a conduit, and an air bag is fixedly connected to the bottom of the pressing rod.

[0008] Preferably, a connecting pipe is fixedly connected to a side of the airbag close to the extrusion spring.

[0009] Preferably, a slide groove is provided inside the shell, and one end of the support rod slides in the slide groove.

[0010] Preferably, the receiving wheel is rotationally connected to the vibration wheel via a belt.

[0011] Preferably, a support spring is provided inside the airbag to automatically restore the recording plate to a horizontal level when the recording plate is no longer pressed.

[0012] Preferably, a protrusion is provided at the bottom of the support rod.

[0013] Preferably, the air extraction box is connected to the air spring via a conduit.

[0014] Preferably, vibration rods are interspersed on the surface of the vibration wheel. When the vibration wheel rotates, under the action of centrifugal force, the vibration rods interspersed on the surface of the vibration wheel move away from the wheel center and collide with the bottom of the recording plate above, causing the recording plate to vibrate, so that an adjusting force is exerted between the fingerprint and the recording plate, and the deformed part of the fingerprint on the surface of the recording plate is adjusted and restored.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides an adjustable fingerprint input device based on the Internet of Things, which has the following beneficial effects:

[0017] 1. The adjustable fingerprint input device based on the Internet of Things uses a support rod and an extrusion rod in combination. When entering a fingerprint, an employee needs to press the fingerprint onto the surface of the recording board with his or her fingers.

[0018] When there is no intersecting force between the fingerprint and the recording plate, the recording plate can recognize the fingerprint, so that the fingerprint can be recorded normally. When there is an intersecting force between the fingerprint and the recording plate, the recording plate is pushed by the fingerprint to drive the support rod to move horizontally. The movement of the support rod causes the squeezing rod to be squeezed through the protrusion set at the bottom. The squeezing rod is squeezed and moves downward to squeeze the airbag below. The squeezed airbag conducts the internal gas to the regulating air box through the connecting pipe. The air pressure in the regulating air box increases to push the receiving plate upward. The receiving plate moves up to drive the receiving rod upward, causing the recording plate to deflect, which is perpendicular to the pressing force of the fingerprint.

[0019] When the receiving rod moves upward, it will mesh with the receiving wheel. The receiving wheel rotates and drives the vibration wheel to rotate through the belt. Under the action of centrifugal force, the vibration rods interspersed on the surface of the vibration wheel move away from the wheel center and collide with the bottom of the collecting plate above, causing the collecting plate to vibrate. This makes the fingerprint and the collecting plate have an adjusting force, and the deformed part of the fingerprint on the surface of the collecting plate is adjusted and restored. Therefore, when the fingerprint and the fingerprint entry plate generate an interlaced force, the angle of the fingerprint entry plate is automatically adjusted, so that the fingerprint is no longer deformed and the entry is successful.

[0020] 2. The adjustable fingerprint input device based on the Internet of Things uses an air spring in conjunction with an air pumping box. When the extrusion rod is squeezed and moved downward, the connecting rod is driven to move downward synchronously, and the connecting rod drives the air pumping plate to move downward, thereby expanding the space of the air pumping box. Since the air pumping box is connected to the air spring through a conduit, when the space inside the air pumping box becomes larger, the air pressure inside the air spring decreases, and the elastic force of the air spring decreases, so that the recording plate will not be subject to a large resistance from the air spring when deflected, thereby achieving the effect of reducing the elastic force of the air spring when adjusting the angle of the recording plate to prevent obstruction of the adjustment process.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-4, an adjustable fingerprint input device based on the Internet of Things, including a shell 1, the material of the shell 1 is anti-corrosion plastic, which can effectively prevent the device from being corroded, greatly prolong the service life of the equipment, reduce the production cost, and play an indispensable role in the enterprise. A slide groove is opened inside the shell 1, and one end of the support rod 11 slides in the slide groove. A recording plate 2 is inserted on the top of the shell 1, and an extrusion spring 3 is fixedly connected to the bottom of the recording plate 2. An adjusting air box 4 is fixedly connected to the inner bottom wall of the shell 1, and a receiving plate 5 is slidably connected to the inside of the adjusting air box 4. A receiving rod 6 is fixedly connected to the top of the receiving plate 5, and a receiving wheel 7 is meshedly connected to the side of the receiving rod 6. The receiving wheel 7 is rotatably connected to a vibration wheel 16 through a belt, and a vibration wheel 16 is rotatably connected to the upper part of the receiving wheel 7 through a belt. A vibration rod is inserted on the surface of the vibration wheel 16. When the vibration wheel 16 rotates, the vibration rod inserted on the surface of the vibration wheel 16 moves away from the wheel center under the action of centrifugal force, and The bottom of the upper recording plate 2 hits, causing the recording plate 2 to vibrate, so that the fingerprint and the recording plate 2 have an adjusting force, and the deformed part of the fingerprint on the surface of the recording plate 2 is adjusted and restored. The side of the recording plate 2 is fixedly connected with a support rod 11, and a protrusion is provided at the bottom of the support rod 11. The bottom of the support rod 11 is slidably connected with an extrusion rod 10, and the side of the extrusion rod 10 is fixedly connected with a connecting rod 14. The top of the connecting rod 14 is fixedly connected with a suction plate 15, and the side of the suction plate 15 is slidably connected with an suction box 13. The material of the suction box 13 is stainless steel, which can effectively prevent the equipment from being corroded. The suction box 13 is connected to the air spring 12 through a conduit, and the top of the suction box 13 is fixedly connected with the air spring 12 through a conduit. The bottom of the extrusion rod 10 is fixedly connected with an air bag 9, and a supporting spring is provided inside the air bag 9. When the recording plate 2 is no longer pressed, the recording plate 2 is automatically restored to a horizontal level, and the side of the air bag 9 close to the extrusion spring 3 is fixedly connected with a connecting pipe 8.

[0028] When recording fingerprints, employees are required to press the fingerprints onto the surface of the recording plate 2 with their fingers.

[0029] When there is no intersecting force between the fingerprint and the recording plate 2, the recording plate 2 can recognize the fingerprint, so that the fingerprint is normally recorded. When there is an intersecting force between the fingerprint and the recording plate 2, the recording plate 2 is pushed by the fingerprint to drive the support rod 11 to move horizontally. The support rod 11 moves and squeezes the squeezing rod 10 through the protrusion set at the bottom. The squeezing rod 10 is squeezed and moves downward to squeeze the airbag 9 below. The airbag 9 is squeezed and the internal gas is conducted to the regulating air box 4 through the connecting pipe 8. The air pressure in the regulating air box 4 increases to push the receiving plate 5 upward. The receiving plate 5 moves upward to drive the receiving rod 6 upward, so that the recording plate 2 is deflected, which is perpendicular to the pressing force of the fingerprint.

[0030] When the receiving rod 6 moves upward, it will mesh with the receiving wheel 7. The receiving wheel 7 rotates and drives the vibration wheel 16 to rotate through the belt. Under the action of centrifugal force, the vibration rods interspersed on the surface of the vibration wheel 16 move away from the wheel center and collide with the bottom of the upper recording plate 2, causing the recording plate 2 to vibrate, so that the fingerprint and the recording plate 2 have an adjusting force, and the deformed part of the fingerprint on the surface of the recording plate 2 is adjusted and restored, thereby achieving the effect of automatically adjusting the angle of the fingerprint recording plate when the fingerprint and the fingerprint recording plate generate an interlaced force, so that the fingerprint is no longer deformed and the recording is easy to succeed.

[0031] When the extrusion rod 10 is squeezed and moved downward, the connecting rod 14 is driven to move downward synchronously, and the connecting rod 14 drives the vacuum plate 15 to move downward, thereby expanding the space of the vacuum box 13. Since the vacuum box 13 is connected to the air spring 12 through a conduit, when the space inside the vacuum box 13 becomes larger, the air pressure inside the air spring 12 is reduced, and the elastic force of the air spring 12 is reduced, so that the recording plate 2 will not be subject to a large resistance from the air spring 12 when deflecting, thereby achieving the effect of reducing the elastic force of the air spring 12 when adjusting the angle of the recording plate 2 to prevent obstruction of the adjustment process.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
