Example Embodiment

[0070] Combine below figure 1 , figure 2 with image 3 The specific structure and working principle of the barrier type mechanical anti-theft lock proposed by the present invention are described in detail.

[0071] 1. The lock box (1) is made of steel plate, the front steel plate thickness is 5mm, the back (indoor side) steel plate thickness is 4mm, and the surrounding steel plate thickness is 3mm.

[0072] 2. The key is a rectangular sheet with a thickness of 0.5mm, a width of 27mm, a working length of 32mm, and a total length of 55mm. In the upper working area, 24 positions are arranged according to the rules, and 12 positions are randomly selected to open holes with a diameter of 3.2mm. There are 6 rows in the horizontal direction, the hole distance is 6.4mm, and the edge distance between two adjacent holes is 3.2mm. There are 4 rows in the longitudinal direction (the depth of the keyhole), the hole spacing is 5.2mm, and the margin between two adjacent holes is 2mm. The key b...

Abstract

The invention relates to a blocking type mechanical anti-theft lock which comprises a lock core and a lock hole and is characterized in that the lock core is formed by laminating a plurality of steel plates; the steel plates are provided with elastic body holes; the elastic body holes are ranked in parallel, vertically through and perpendicular to slit-type lock holes at the horizontal direction; and a lock hole (5) is formed on the upper surface of the downmost steel plate, and a hole sealing plate (7) arranged on the lower portion of the lock hole and an unlocking sliding plate (10) arranged on the upper portion of the lock hole are movable pieces. During unlocking, the movable hole sealing plate (7) transversally moves for an elastic body hole diameter distance to seal the middle of the elastic body hole and block contact and connection between holes in vertical mode. By means of the blocking type mechanical anti-theft lock, keys are only inserted in or pulled out, no rotation is required, unlocking can be completed by rotating a handle for 90 degrees, and keys are not required during locking. The blocking type mechanical anti-theft lock is in pure mechanical structure and is low in manufacture cost, simple to operate, and strong in damage resistant capabilities including drilling-resistant and the like.

Description

technical field [0001] The invention relates to a mechanical anti-theft lock, in particular to a barrier type mechanical anti-theft lock. Background technique [0002] A mechanical lock generally consists of a lock cylinder, a transmission mechanism, and a dead bolt (bolt). The lock cylinder is the key component, which contains the tumbler group. The movement and movement range of the marbles are determined by the key. Only when the correct key is encountered, the marbles can move to the correct position, and the lock cylinder can rotate or move in other forms, and then drive the transmission mechanism to complete the unlocking action. As the driving force, the turn key is the main driving method. Because there is a certain connection between the pin and the transmission mechanism, technical opening locks often use this connection in combination with special special tools to move the pin or other related components to the required position, and finally open the lock.
