Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of unlocking and timing devices, and specifically relates to an unlocking and timing device for examination rooms. Background Technology
[0002] Police officers and other professionals may encounter situations requiring them to pick locks while performing their duties. Therefore, lock-picking skills are usually assessed among these professionals to test their skills. Currently, when assessing the lock-picking skills of such professionals, an examiner is usually required to time them individually to obtain the assessment score. The drawback of this timing method is that manual timing is prone to errors and inaccurate timing. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an unlocking and timing device for examination rooms to solve the problems existing in the prior art.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A lock-unlocking timing device for examination rooms includes a lock holder with several lock positioning holes. Locks are detachably connected to the positioning holes. The device also includes a lock fixing device to secure the locks to the positioning holes, a laser sensor for sensing unlocking signals, and a control system. The control system includes a housing containing a processor. The laser sensor is connected to the processor, which is also connected to a timing module, a counting module, and a display module. The timing module records the time of a single unlock and the sum of multiple unlock times; the counting module displays the number of unlocks; and the display module displays the unlock time.
[0006] Preferably, the lock holder includes a panel with a plurality of positioning holes arranged on the panel. A pressure plate is slidably connected in the positioning holes. The holder also includes a screw. A threaded hole is provided at the top of the positioning holes. The bottom end of the screw passes through the threaded hole and is rotatably connected to the top of the pressure plate. A rotating handle is formed at the top of the screw.
[0007] Rotating the screw will cause the pressure plate to move up and down, thus fixing the lock.
[0008] Preferably, the laser sensing device includes laser emitters located at both ends of the inner side of the panel. The laser lines emitted by the two laser emitters are located above the lock. After the lock is unlocked, the bolt passes through the laser lines, generating a signal that is received by the processor.
[0009] Preferably, a sliding rail is provided on the inner side of the panel, and the two laser emitters are slidably connected on the sliding rail.
[0010] Preferably, the bottom of the panel is provided with a clamping member to fix the panel to the table surface.
[0011] Preferably, the processor is also connected to a Bluetooth module to enable screen mirroring.
[0012] Preferably, a folding rack is provided on the back of the housing for easy storage.
[0013] In use, several locks are fixed in the positioning holes. At the same time, the control system displays the number of locks to be unlocked and prepares for timing. After successful unlocking, the bolt rotates upward and passes through the laser line to obtain a successful unlocking signal. The timing module records the unlocking time. Then, the operator returns the bolt to its original position and proceeds to unlock the next lock. This process is repeated until all locks are unlocked. The timing module records the unlocking time for each lock and the total unlocking time, which can be displayed by the display module.
[0014] In summary, the present invention has the following main advantages:
[0015] This application uses a laser sensing device to obtain the unlocking signal, and includes a processor, a timing module, and a counting module to record and display the unlocking time, making the timing more accurate and efficient. Attached Figure Description

[0019] Example
[0020] refer to Figures 1 to 3 This embodiment describes a lock-unlocking and timing device for an examination room, comprising a lock holder 1 with several lock positioning holes 2 formed thereon. A lock is detachably connected to each positioning hole. The device also includes a lock fixing device to secure the lock to the positioning holes. Specifically, the lock holder includes a panel 3 with several positioning holes 2 arranged on it. A pressure plate 4 is slidably connected to each positioning hole. The device also includes a screw 5 with a threaded hole 6 at the top of each positioning hole. The bottom end of the screw passes through the threaded hole and is rotatably connected to the top of the pressure plate. A rotating handle 7 is formed at the top of the screw. Rotating the screw causes the pressure plate to move up and down, thus securing the lock.
[0021] It also includes a laser sensing device, which is used to sense the unlocking signal. The laser sensing device includes laser emitters 8 set on both ends of the inner side of the panel. The laser lines emitted by the two laser emitters are located above the lock. After the lock is unlocked, the bolt passes through the laser line, generates a signal, and is received by the processor. A sliding rail 9 is provided on the inner side of the panel, and the two laser emitters are slidably connected to the sliding rail.
[0022] The system includes a housing 10, with a folding frame 11 on the back for easy placement. A processor 12 is located inside the housing. The laser sensing device is connected to the processor. The processor is also connected to a timing module 13, a counting module 14, and a display module 15. The timing module is used to record the time of a single unlocking and the sum of the times of multiple unlockings. The counting module is used to display the number of unlockings. The display module is used to display the unlocking time.
[0023] The bottom of the panel is provided with a clamping member 16, which fixes the panel to the table surface.
[0024] In this embodiment, the processor is also connected to a Bluetooth module 17, which enables the screen projection function.
[0025] In use, several locks are fixed in the positioning holes. At the same time, the control system displays the number of locks to be unlocked and prepares for timing. After successful unlocking, the bolt rotates upward and passes through the laser line to obtain a successful unlocking signal. The timing module records the unlocking time. Then, the operator returns the bolt to its original position and proceeds to unlock the next lock. This process is repeated until all locks are unlocked. The timing module records the unlocking time for each lock and the total unlocking time, which can be displayed by the display module.
