[0001] This application relates to the field of security lock technology, and in particular to a security lock structure. Background Technology
[0002] Cabinets used to store valuables or cash (such as ATM cabinets or safes) are usually equipped with security locks to prevent theft, thus ensuring the safety of the cabinet and preventing the valuables inside from being easily lost.
[0003] Existing security lock mechanisms are not secure enough after locking. They can be easily opened by pulling or prying from the outside, which can easily lead to the loss of the property protected by the security lock and is not conducive to its widespread use. Therefore, this application proposes a security lock structure to solve the above problems. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a safety lock structure that overcomes the deficiencies of the prior art and aims to solve the problems in the background art.
[0005] To achieve the above objectives, this application adopts the following technical solution: a safety lock structure, including an outer shell, a drive motor installed on the inner wall of the outer shell, a gear one fixedly connected to the power output shaft of the drive motor, a gear two rotatably installed on the inner bottom of the outer shell, a crown tooth fixedly installed on the top of the gear two, one end of a spring fixedly connected to the inner wall of the outer shell, a push bar fixedly connected to the other end of the spring, a rack fixedly installed on the side of the push bar near the gear two, one end of a torsion spring installed on the inner wall of the outer shell, the other end of the torsion spring installed on the inner wall of a connecting block, a push rod rotatably connected to the end of the connecting block away from the push bar, and the bottom of the connecting block rotatably connected to the inner bottom of the outer shell.
[0006] In a preferred embodiment, two positioning plates are symmetrically fixedly installed on the inner bottom of the outer shell, and the drive motor is fixedly installed on the inner wall of the two positioning plates.
[0007] By adopting the above technical solution, the two positioning plates can be used to position the two sides of the drive motor, ensuring the stability of the drive motor during operation, preventing it from shaking, and ensuring that it can operate stably in the initial position.
[0008] In a preferred embodiment, the outer edge of the first gear meshes with the crown tooth, a limiting rod is fixedly installed at the bottom of the second gear, a limiting hole is opened at the inner bottom of the outer shell, and the limiting rod is rotatably connected to the inner wall of the limiting hole.
[0009] By adopting the above technical solution, the rotation of gear one can cooperate with the crown tooth to drive gear two to rotate. The setting of the limiting rod can ensure that gear two rotates stably around the limiting rod as the axis and will not easily disengage from the position.
[0010] In a preferred embodiment, the outer edge teeth of the rack mesh with the outer edge teeth of the gear two, a slider is fixedly installed at the bottom of the pusher, a groove is provided at the inner bottom of the outer shell, the slider is slidably connected to the inner wall of the groove, and the bottom of the pusher is slidably connected to the inner bottom of the outer shell.
[0011] By adopting the above technical solution, the rotation of gear two can drive the push bar to slide at the inner bottom of the outer shell, thereby pushing one side of the push bar to drive the connecting block to rotate, which in turn drives the push rod to move. The push rod is slidably connected to the inner wall of the slide groove through the slider, thus ensuring that the push bar can stably slide against the inner bottom of the outer shell.
[0012] In one preferred embodiment, the inner wall of the outer casing has a through hole, and the push rod is adapted to slide and connect to the inner wall of the through hole.
[0013] By adopting the above technical solution, the connecting block can pull the push rod to slide stably on the inner wall of the through hole, thereby achieving contraction and reset.
[0014] In a preferred embodiment, a guide groove is provided on the inner bottom of the outer casing, and the push rod is slidably connected to the inner wall of the guide groove on the side near the connecting block.
[0015] By adopting the above technical solution, the stability of the push rod when it moves close to the connecting block can be guaranteed, ensuring that it can slide stably on the inner wall of the guide groove and will not easily deviate to the sides of the inner wall of the outer shell.
[0016] The beneficial effects of this application are:
[0017] 1. This safety lock structure uses a drive motor to rotate gear one, which in turn drives the crown gear and gear two to rotate. The rotation of gear two drives the push bar to slide at the bottom of the outer shell via a rack. The push bar then pushes one end of the connecting block to move, causing the connecting block to rotate at the bottom of the outer shell. This drags the push rod to slide along the inner wall of the through hole, achieving retraction. After the push bar disengages from the connecting block, the torsion spring's restoring force can drive the connecting block back to its original position, thereby causing the push rod to extend and retract to its initial state. The spring ensures effective engagement of gear two and the rack, preventing the lock body from being easily pried open from the outside, thus improving security and protection.
[0018] 2. This safety lock structure, by setting a slider to slide on the inner wall of the groove, can ensure that the push bar can stably fit against the inner bottom of the outer shell and slide in a straight line. Attached Figure Description

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0026] Reference Figure 1-5 A safety lock structure includes an outer shell 1. A drive motor 2 is installed on the inner wall of the outer shell 1. A gear 3 is fixedly connected to the power output shaft of the drive motor 2. A gear 4 is rotatably installed on the inner bottom of the outer shell 1. A crown tooth 5 is fixedly installed on the top of the gear 4. One end of a spring 6 is fixedly connected to the inner wall of the outer shell 1. A push bar 7 is fixedly connected to the other end of the spring 6. A rack 8 is fixedly installed on the side of the push bar 7 near the gear 4. One end of a torsion spring 11 is installed on the inner wall of the outer shell 1. The other end of the torsion spring 11 is installed on the inner wall of a connecting block 12. A push rod 13 is rotatably connected to the end of the connecting block 12 away from the push bar 7. The bottom of the connecting block 12 is rotatably connected to the inner bottom of the outer shell 1.
[0027] See Figure 4 Two positioning plates 14 are symmetrically fixedly installed on the inner bottom of the outer shell 1. The drive motor 2 is fixedly installed on the inner wall of the two positioning plates 14, so that the two positioning plates 14 can be used to position the two sides of the drive motor 2, ensuring the stability of the drive motor 2 during operation, ensuring that it will not shake during operation, and can operate stably in the initial position.
[0028] See Figure 4 and Figure 5 The outer edge of gear 3 meshes with crown tooth 5. A limit rod is fixedly installed at the bottom of gear 4. A limit hole 15 is opened at the bottom of the outer shell 1, and the limit rod is rotatably connected to the inner wall of the limit hole 15, so that the rotation of gear 3 can cooperate with crown tooth 5 to drive gear 4 to rotate. The limit rod can ensure that gear 4 rotates stably around the limit rod as the axis and will not easily disengage from the position.
[0029] See Figure 5 The outer edge teeth of rack 8 mesh with the outer edge teeth of gear 4. A slider 10 is fixedly installed at the bottom of push bar 7. A groove 9 is provided at the inner bottom of outer shell 1. The slider 10 is slidably connected to the inner wall of groove 9. The bottom of push bar 7 is slidably connected to the inner bottom of outer shell 1, so that the rotation of gear 4 can drive push bar 7 to slide at the inner bottom of outer shell 1, thereby pushing one side of push bar 7 to push connecting block 12 to rotate, thereby driving push rod 13 to move. Through the slider 10 slidably connected to the inner wall of groove 9, it can be ensured that push bar 7 can stably slide against the inner bottom of outer shell 1.
[0030] See Figure 4 and Figure 5 The inner wall of the outer shell 1 has a through hole 16. The push rod 13 is adapted to slide and connect to the inner wall of the through hole 16, so that the connecting block 12 can pull the push rod 13 to slide stably on the inner wall of the through hole 16, thereby achieving retraction and reset.
[0031] See Figure 4 The bottom of the outer shell 1 is provided with a guide groove 17. The push rod 13 is slidably connected to the inner wall of the guide groove 17 on the side near the connecting block 12, so as to ensure the stability of the push rod 13 when it moves near the connecting block 12, and ensure that it can slide stably on the inner wall of the guide groove 17, and will not easily deviate to the sides of the inner wall of the outer shell 1.
[0032] Working principle: When using this device, the drive motor 2 first drives the gear 3 to rotate, which in turn drives the crown tooth 5 and the gear 4 to rotate. The rotation of the gear 4 drives the push bar 7 to slide on the inner bottom of the outer shell 1 through the rack 8. Then, the push bar 7 pushes one end of the connecting block 12 to move, and the connecting block 12 rotates on the inner bottom of the outer shell 1. This drags the push rod 13 to slide on the inner wall of the through hole 16 to achieve retraction. After the push bar 7 is disengaged from the connecting block 12, the restoring force of the torsion spring 11 can drive the connecting block 12 to return to its original position, which can then drive the push rod 13 to extend and retract to its initial state. The spring 6 can ensure the effective meshing of the gear 4 and the rack 8. At the same time, the slider 10 is slidably connected to the inner wall of the slide groove 9 to ensure that the push bar 7 slides in a straight line on the inner bottom of the outer shell 1.
