Technical Field

[0001] The utility model relates to the technical field of padlocks, in particular to a high-security low-interaction pin padlock. Background Art

[0002] Pin-tumbler padlocks are a common and widely used type of locks. Their basic working principle relies on a combination of pins and springs, which are unlocked by matching the height of the key teeth. Nowadays, a suitable key is usually inserted into the padlock, so that the internal lock pin, under the action of the key teeth, pushes up the drive pin, so that the drive pin squeezes the spring and keeps the end of the drive pin flush with the opening of the active cavity, contacting the limit of the lock core, so that the lock core can be unlocked by turning the key.

[0003] However, common pin tumbler padlocks are easily inserted into locks with the same type of key. Although there are differences in the tooth sizes, there is still a risk of opening the same type of lock, which reduces its confidentiality effect and affects the security protection effect. In view of this, we propose a high-confidentiality and low-mutual-opening pin tumbler padlock. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and provides a high-security and low-interaction-opening pin-tumbler padlock.

[0010] Preferably, the limiting assembly includes a driving pin, a second spring is connected to the back end of the driving pin, and the other end of the second spring is connected to the first active cavity wall body at a corresponding position.

[0011] Preferably, a guide collar is sleeved on the outer ring surface of the driving pin, an auxiliary slider is welded on the outer surface wall of the guide collar, and a positioning pin is connected to one side wall of a plurality of the auxiliary sliders.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model utilizes the elasticity of the second spring so that the driving pin, under the elastic action of the second spring, drives the guide ring and the auxiliary sliding block to move toward the lock core, so that the positioning pin is inserted into the positioning slot provided on the outer wall of the first spring. The plurality of positioning slots are adapted to the lengths of the positioning pins corresponding to the positions, so that a key with a tooth size adapted thereto can squeeze the plurality of lock pins into the second active cavity corresponding to the positions. When the lock pin moves to the second active cavity corresponding to the position, the driving pin can be squeezed to move, so that the pushing end of the driving pin and the limiting end of the lock pin are kept flush, thereby making the positioning pins of different sizes disengage from the adapted positioning slots and contact the position of the lock core to lock the position, thereby improving the confidentiality of the padlock and reducing the risk of being opened by a key of the same model.

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-3As shown, the utility model proposes a high-confidentiality low-interactive pin padlock, comprising a lock body 1, wherein a transverse cavity, a first vertical cavity and a second vertical cavity are provided in the lock body 1, a copper pin 3 is arranged in the transverse cavity, a lock core 5 is arranged in the second vertical cavity, and a paddle at the top of the lock core 5 is arranged at the paddle position at the bottom of the copper pin 3, so as to facilitate the contraction of the locking head of the copper pin 3 during the rotation of the lock core 5; one end of the lock beam 2 passes through the top opening of the first vertical cavity, and is connected to the top of the first spring 4 installed on the bottom wall of the first vertical cavity, so as to facilitate the other end of the lock beam 2 that is released from the limit to be separated from the lock body 1; a plurality of lock pins 6 are respectively arranged in a plurality of second active cavities provided on the lock core 5, and the sizes of the plurality of lock pins 6 are different, and the plurality of second active cavities all correspond to the positions of the plurality of first active cavities provided on one side wall of the second vertical cavity.

[0021] Furthermore, a limiting component 7 is provided on one side of each of the plurality of lock pins 6 for further limiting the position of the lock core 5. A first movable cavity is provided on one side wall of the second vertical cavity. Multiple groups of limiting components 7 are respectively arranged in the first movable cavity corresponding to the position. The limiting component 7 includes a driving pin 71, a second spring 72, a guide collar 73, an auxiliary slider 74 and a positioning latch 75. The driving pin 71 is located in the first movable cavity. The back end of the driving pin 71 is connected to the end of the second spring 72 fixedly mounted on the wall of the first movable cavity. Through the setting of the second spring 72, the driving pin 71 can be pushed to the corresponding structure of the first movable cavity and the second movable cavity by the elasticity of the second spring 72 during the resetting process of the lock pin 6, so that part of the structure of the driving pin 71 is located in the first movable cavity and the other part of the structure is located in the second movable cavity, so as to achieve the purpose of positioning the lock core 5, so that the lock core 5 cannot rotate, and thus cannot contact the limiting position of the lock beam 2; the guide collar 73 is fixedly sleeved on the outer ring surface of the driving pin 71 and is provided on the wall of the first movable cavity. The first guide slot 74 is provided on the lock body, and the guide ring 73 cooperates with the first guide slot 74 to help the auxiliary driving pin 71 to maintain stability during the movement; multiple auxiliary sliders 74 are welded on the outer ring surface of the guide ring 73, and multiple auxiliary sliders 74 are arranged in multiple second guide slots provided on the wall body of the first guide slot, further improving the stability of the driving pin 71 during the movement; multiple positioning slots are provided on the outer wall of the lock cylinder 5, and multiple positioning pins 75 are respectively welded on the side walls of multiple auxiliary sliders 74, so that when the driving pin 71 positions the lock cylinder 5, it can drive the positioning pin 75 to be inserted into the positioning slot corresponding to the position, further restricting the position of the lock cylinder 5 and improving the confidentiality of this lock.
