Description

Technical Field

[0001] This utility model belongs to the field of padlock technology, and more specifically, it relates to an anti-knock rotation structure for a padlock. Background Technology

[0002] Padlocks, as a widely used type of lock, play a vital role in daily life, business activities, and industrial fields. From protecting doors and windows in homes to securing warehouses and containers, and temporarily locking public facilities and vehicles, padlocks are ubiquitous, fulfilling their responsibilities of protecting personal property, ensuring business security, and maintaining public order.

[0003] Among various security threats, the violent destruction of padlocks has always been a problem that plagues users, and banging is one of the more common methods. Traditional padlocks have a relatively simple structural design, and the connection between the lock cylinder and the lock body, as well as the way the bolt is secured, are clearly vulnerable to banging. When criminals use tools to bang on a padlock, the impact force on the lock body is easily transmitted to the lock cylinder, causing it to rotate and disengage the bolt, ultimately making the padlock easily open and threatening property security. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an anti-knock rotating structure for padlocks, thereby solving the technical problem that traditional padlock rotating structures often fail to prevent knocking and have poor security.

[0005] The purpose and effect of this utility model's anti-knock rotation structure for a padlock are achieved through the following specific technical means:

[0006] An anti-knock rotating structure for a padlock includes a bracket, one end of which has a bracket groove, and a rotating shaft passes through the bracket groove, allowing the rotating shaft to rotate within the bracket groove. A torsion spring is provided between the bracket groove and the rotating shaft. A swing arm is provided at the end of the bracket away from the torsion spring, and a motor is provided at the end of the swing arm away from the bracket. The main shaft of the motor faces the swing arm, and a steel ball is provided on one side of the bracket.

[0007] As a further embodiment of this utility model, a cross-shaped groove is provided at the end of the swing arm away from the bracket, and the end of the swing arm away from the bracket is assembled with a cross-shaped protrusion on the motor spindle through the cross-shaped groove.

[0008] As a further embodiment of this utility model, the end of the rotating shaft away from the torsion spring is assembled with the swing arm, and a rotating groove is provided at the end of the rotating shaft away from the torsion spring. The protrusion at one end of the swing arm is rotatably disposed in the rotating groove.

[0009] As a further embodiment of this utility model, the torsion spring is mounted on the rotating shaft.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] A torsion spring is held in place on a rotating shaft, which is supported at both ends by brackets. When the shaft is subjected to radial thrust, it rotates within the bracket slots. A swing arm is fitted onto the motor and assembled with the shaft, which is then fixed in place by the brackets. When unlocking, the motor drives the swing arm to rotate, which in turn pushes the shaft, thus unlocking. After the motor returns to its original position, the shaft, under the thrust of the torsion spring, pushes the steel ball back to lock the shackle, thus locking the lock. Compared to traditional padlocks that rely on a connection between the lock cylinder and lock body or a fixed bolt, this design offers anti-knock features, effectively preventing knocking and improving security.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] Example:

[0020] As attached Figure 1 To be continued Figure 4 As shown:

[0021] This utility model provides an anti-knock rotation structure for a padlock, including a bracket 100. One end of the bracket 100 has a bracket groove 102, and a rotating shaft 101 passes through the bracket groove 102. Both ends of the rotating shaft 101 are supported on the bracket 100, and the rotating shaft 101 can rotate within the bracket groove 102. A torsion spring 103 is provided between the bracket groove 102 and the rotating shaft 101. The torsion spring 103 is locked onto the rotating shaft 101. After the motor 105 is reset, the torsion spring 103 can push the rotating shaft 101. A swing arm 104 is provided at the end of the bracket 100 away from the torsion spring 103. A motor 105 is provided at the end of the swing arm 104 away from the bracket 100. The main shaft of the motor 105 faces the swing arm 104. A steel ball 107 is provided on one side of the bracket 100. When the motor 105 is reset, the steel ball 107 will be pressed back into position by the external locking beam and lock the locking beam.

[0022] The end of the swing arm 104 away from the bracket 100 is provided with a cross-shaped slot. The end of the swing arm 104 away from the bracket 100 is assembled with the cross-shaped protrusion on the main shaft of the motor 105 through the cross-shaped slot. After the assembly is completed, the motor 105 is fixed by the bracket 100, thereby ensuring the stability of the entire structure during operation.

[0023] The end of the rotating shaft 101 away from the torsion spring 103 is assembled with the swing arm 104. The end of the rotating shaft 101 away from the torsion spring 103 has a rotating groove 106. The protrusion at one end of the swing arm 104 is rotatably disposed in the rotating groove 106. When the motor 105 starts and drives the swing arm 104 to rotate, the protrusion at one end of the swing arm 104 will also rotate in the rotating groove 106 and rotate to the edge of the rotating groove 106. The rotating shaft 101 is pushed through the rotating groove 106 to realize the relevant unlocking operation.

[0024] The specific usage and function of this embodiment are as follows: When unlocking, the motor 105 drives the swing arm 104 to rotate, thereby causing the swing arm 104 to push the rotating shaft 101, which rotates within the bracket groove 102, thus unlocking. After the motor 105 resets, the rotating shaft 101 rotates in the opposite direction within the bracket groove 102 under the induction action of the torsion spring 103. When the external lock beam is pressed back, it pushes the steel ball 107 to reset the locking post and lock the external lock beam, thus locking. This structure uses the unlocking method of rotating shaft 101, torsion spring 103, swing arm 104, motor 105, and steel ball 107. Compared with the traditional padlock's connection method between the lock cylinder and lock body and the fixing method of the lock tongue, this structure can effectively disperse and resolve the striking force when facing malicious external knocking, avoiding the lock from being opened due to knocking, improving the security of the padlock, and providing more reliable protection for the safety of items.
