Description

Technical Field

[0001] The utility model relates to the technical field of access control system identification, in particular to an identification device that can be used in an access control system. Background Art

[0002] Fingerprints are the lines of skin on the tips of human fingers. They form before birth and remain unchanged as individuals grow, only their degree of visibility changes. Furthermore, each person's fingerprint is unique. Fingerprint recognition technology is often used in access control systems for identity verification, offering advantages such as high efficiency and accuracy.

[0003] However, the existing fingerprint recognition device still has certain defects when in use. The collection terminal on the existing fingerprint recognition device is easy to accumulate dust. When not used for a long time, the dust will cover and corrode the collection window on the collection terminal, affecting the accuracy of fingerprint collection.

[0004] For example, Chinese patent CN212515859U discloses a fingerprint recognition device for an access control system. By providing a cover that can move up and down, the card seat and card slot at the bottom of the cover can be used to engage the collection terminal seat. The card slot engages the top of the collection terminal seat to prevent the collection window on the collection terminal seat from being exposed. This can effectively protect the collection window from dust, effectively extend the service life of the collection window, and improve the accuracy of the collection.

[0005] However, if the identification device is used outdoors, the strong sunlight outdoors will shine on the collection terminal, which will affect the collection of fingerprints.

[0006] For this reason, we urgently need to provide an identification device for an access control system that can provide sunshade. Utility Model Content

[0007] The purpose of the present invention is to provide an identification device that can be used in an access control system, so as to solve the problem raised in the above background technology that when the identification device is used outdoors, strong sunlight outdoors will affect the collection of fingerprints when it shines on the collection terminal.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an identification device that can be used for an access control system, comprising a mounting plate for installing the access control system identification device and a fingerprint identification terminal, the fingerprint identification terminal being fixedly connected to the front left side of the mounting plate, and an identification mechanism being installed on the front side of the mounting plate.

[0010] A further improvement is that the inner side of the limit frame is slidably connected to the outer side of the gear rod, so that when the first spring drives the gear rod to move, the gear rod can only slide along the inner side of the limit frame.

[0011] A further improvement is that the large gear and the driven gear are meshed, and the driving gear and the outer end of the gear rod are meshed, so that when the gear rod is moved, the driving gear can be driven to move, and the rotating rod can be rotated.

[0012] A further improvement is that a threaded hole is opened in the middle position inside the sliding block, the outer side of the sliding block is slidingly connected to the inner side of the rectangular sleeve, the outer side of the threaded rod is threadedly connected to the inner side of the threaded hole, and the lower side of the top plate abuts against the upper side of the sliding block, so that when the driven gear rotates and drives the threaded rod in the threaded hole to rotate, it can drive the sliding block to slide along the inner side of the sliding block.

[0013] A further improvement is that a cleaning mechanism is provided at the front right end of the mounting plate, the cleaning mechanism includes a storage box fixedly connected to the front right end of the mounting plate, the upper end of the storage box is connected to a sealing plate, the front upper right end of the storage box is fixedly connected to a U-shaped frame, the inner front end of the U-shaped frame is fixedly connected to a second spring, the rear end of the second spring is fixedly connected to a connecting ring, and the inner side of the connecting ring is fixedly connected to an insertion rod.

[0014] A further improvement is that a sliding groove is provided at the inner upper end of the storage box, and the outer sides of the front and rear ends of the sealing plate are slidably connected to the inner side of the sliding groove, so that after the sealing plate is slid to the inner side of the sliding groove, the upper end of the storage box can be closed.

[0016] In summary, the present application discloses an identification device that can be used in an access control system.

[0017] According to this technical solution, when the finger is pressed onto the collection end seat to collect the fingerprint, the sun visors on the left and right ends of the collection end seat will block the sunlight, the sunlight irradiated by the front end of the collection end seat will be blocked by the staff recording the fingerprint, and the upper end of the collection end seat will be blocked by the raised protective cover, so that light from all angles will be blocked during fingerprint collection, which will not affect the collection of fingerprints by the collection end seat.

[0018] Furthermore, by placing the entire pack of wet wipes upside down into the storage box, and passing the wet wipe to be drawn out at the outer end through the paper withdrawal port at the lower end of the storage box, the sealing plate is slid into the slide groove at the upper end of the inner side of the storage box, and then the second spring rebounds and pushes the connecting ring backward, driving the insertion rod to move backward along the inner side of the slide hole until the rear end of the insertion rod moves backward into the insertion hole, and the sealing plate is fixed to the slide groove, so that the upper end of the storage box is closed. In this way, before the staff touches the collection end seat with their fingers, they can first draw a wet wipe from the storage box and wipe their fingers, which can make the identification during collection more accurate and ensure the cleanliness of the surface of the collection end seat.

After the closing plate 402 is slid to the inner side of the slide groove, the second spring 404 rebounds and pushes the connecting ring 405 backward, driving the insertion rod 406 to move backward along the inner side of the slide hole until the rear end of the insertion rod 406 moves backward into the socket, so that the closing plate 402 can be fixed to the slide groove and the upper end of the storage box 401 can be closed, so that the wet tissues used for cleaning in the storage box 401 can be added after use.

[0033] Working principle: When performing fingerprint recognition, the finger whose fingerprint needs to be collected moves between the rectangular cover plate 302, and at the same time, the other fingers first touch the front end of the gear rod 317, pressing the gear rod 317 backward. During the backward movement of the gear rod 317, the first spring 316 is compressed, and at the same time drives the driving gear 306 to rotate, so that the rotating rod 304 rotates, thereby driving the large gear 305 at the lower end to rotate, so that the driven gear 309 and the threaded rod 308 inside it rotate, driving the sliding block 311 at the outer end of the threaded rod 308 to slide up along the inner side of the rectangular cover plate 302, and at the same time driving the connecting frame 318 and the shield 319 together. After the hand is removed from the collecting position, the first spring 316 rebounds and drives the gear rod 317 to move forward, causing the driving gear 306 to rotate in the opposite direction, thereby driving the sliding block 311 to move downward, causing the shield 319 to move down again to the upper side of the bottom frame 301 to cover the laser scanning seat 312 and the collecting end seat 313 for protection.
