Abstract
Description
Technical Field
[0001] The utility model relates to the field of classroom equipment, in particular to a classroom management clock-in device. Background Art
[0002] At present, clocking in means placing a magnetic card on a magnetic card machine so that it can read the relevant content. It specifically refers to staff inserting their attendance cards into the magnetic card machine when they go to and from work to record the time of arrival or departure from the unit. It can be understood as "signing in, registering, and showing ID." In order to record students' attendance on university campuses, teachers generally sign in students by calling their names. However, due to the frequent occurrence of impersonation, in order to better record students' attendance, many campuses now use fingerprint clocking machines to record students' attendance.
[0003] There are currently the following problems;
[0004] Existing fingerprint time clocks are generally divided into networked and offline types. Offline fingerprint time clocks store personnel information and attendance records locally and do not need to be connected to the network, which makes the installation cost and requirements low. They are more suitable for large-scale popularization. However, if a single fingerprint time clock is maliciously damaged, the stored data inside the time clock will be lost or invalidated. Surveillance is generally not installed in universities, so there is a lack of protection measures for the time clocks. Some students also have sufficient motivation to maliciously damage the fingerprint time clocks. Utility Model Content

[0028] Example 1
[0029] Reference Figures 1 to 8 The present embodiment provides a classroom management punching device, including a protective box 100, the interior of the protective box 100 is hollow, the outer wall of the protective box 100 is provided with a first fingerprint hole 101, and one end of the outer wall of the protective box 100 is fixed to the wall by rivets or bolts; a self-locking mechanism 200, the self-locking mechanism 200 includes a push plate 201, a first slide plate 202 and a second slide plate 203, the outer wall of the push plate 201 is provided with a second fingerprint hole 201a with the same shape as the first fingerprint hole 101, the first slide plate 202 and the second slide plate 203 have the same shape and are arranged in a mirror image of a sheet, and the first slide plate 202 and the outer wall of the second slide 203 are both provided with a second fingerprint hole 201a, and the push plate 201, the first slide 202 and the second slide 203 are all slidably connected at the outer wall of the protective box 100; under normal conditions, the first fingerprint hole 101, the second fingerprint hole 201a and the third fingerprint hole 202a do not overlap, so that the time clock set inside the protective box 100 is in a closed state, which can not only protect the fingerprint time clock from human damage to a certain extent, but also prevent dust from contaminating the fingerprint recognition module of the fingerprint time clock, thereby stabilizing the time clocking efficiency of the fingerprint time clock.
[0030] The outer wall of the protective box 100 is provided with a first slide groove 102 at the bottom of the first fingerprint hole 101, and a limit plate 103 is provided at the bottom of the first slide groove 102. The bottom of the push plate 201 is connected to a sliding rod 201c, and the sliding rod 201c is slidably connected inside the first slide groove 102 and passes through the limit plate 103. The top of the push plate 201 is fixedly connected to a shielding plate 201b; under normal circumstances, the shielding plate 201b coincides with the first fingerprint hole 101 of the protective box 100, and the first fingerprint hole 101 is blocked by the shielding plate 201b, so that the interior of the protective box 100 is in a closed state. When fingerprint punching is required, the push plate 201 is pushed to make the sliding rod 201c slide up and down along the direction of the first slide groove 102, causing the second fingerprint hole 201a to coincide with the first fingerprint hole 101 to achieve punching.
[0031] The outer wall of the protective box 100 is provided with a second slide groove 104 on both sides of the first slide groove 102, and one end of the outer wall of the first slide plate 202 and the second slide plate 203 is connected with a sliding pin 202b, and the sliding pins 202b connected to the outer walls of the first slide plate 202 and the second slide plate 203 are respectively slidably connected in different second slide grooves 104. The bottom of the outer wall of the first slide plate 202 and the second slide plate 203 is penetrated by a third slide groove 202c, and the sliding rod 201c sequentially penetrates the third slide groove 202c of the first slide plate 202 and the second slide plate 203, and makes the sliding rod 201c in the third slide groove 20 2c is internally slidably connected; when it is necessary to punch in, as the push plate 201 moves upward, the sliding rod 201c is slidably connected inside the third sliding groove 202c, thereby driving the first slide plate 202 and the second slide plate 203 to move upward until the third fingerprint hole 202a of the first slide plate 202 and the second slide plate 203 coincide with each other. In this state, the first fingerprint hole 101, the second fingerprint hole 201a, and the third fingerprint hole 202a are all in a coincidence state, so that fingerprint recognition can be performed. The function of the first slide plate 202 and the second slide plate 203 is to further protect the punching machine.
[0032] A return spring 103A is connected to the bottom of the limit plate 103, and the other end of the return spring 103A is fixedly connected to the outer wall of the slide rod 201c; the function of the return spring 103A is to provide elastic force for the push plate 201 when there is no external force after the punching is completed, so that the push plate 201, the first slide 202 and the second slide 203 are reset.
[0033] Dust covers are provided on the inner wall of the protection box 100 at the first sliding groove 102 and the second sliding groove 104 .
[0034] The outer wall of the protection box 100 is rotatably connected to a switch plate 105; the switch plate 105 adopts a locking structure, the purpose of which is to facilitate management personnel to collect data from the time clock.
