Description

Blade lock enhanced anti-theft structure

The present invention relates to a blade lock reinforced anti-theft structure, in particular, a design of a card abutting piece and a main latch body pinning by the lower end of the locking piece, thereby increasing the difficulty of the foreign object extending into the main latch of the shackle. According to the effect of strengthening the anti-theft unlocking.

According to the conventional design of the lock type door lock, please refer to the first figure, mainly using the lock (10) preset gate (11) brake hole (12) to the main lock (13) The card body (14) is limited and acts as a slip prohibition structure for the main latch.

However, the main purpose of the door lock setting is to prevent theft. However, the front door lock is locked on the slip prohibition of the main latch (13), and the lock hole (12) is used to open the hole (12) to the main lock. The limit of the latch (13) card body (14) is achieved, so that when theft is stolen, the operator only needs to tilt the locking piece (10) so that the main latch body (13) card body (14) is located at the locking piece (10). On the gateway (11), and synchronously dialing the main latch body (13) to move the tooth (15) inward, it is designed for the above-mentioned anti-theft structure, and should be further strengthened to improve the theft. Difficult.

In view of the fact that there is still room for improvement in the design of the lock structure, the creator is based on years of experience in the manufacture of related products, and has specially developed and developed this creation. Its main purpose is It is to provide a door lock structure that can effectively increase the difficulty of thieves to pirate, and can effectively improve the overall security performance of theft.

Another purpose of the present invention is to design a lower snap-in contact with the main latch body by the lower end of the lock piece, so that when the foreign matter is to be disturbed by the foreign object, the lower card must be dialed off at the same time. The piece and the swaying lock piece enable the main latch body to be located on the sluice of the locking piece, and simultaneously move the main latch body to move inwardly, which is to improve the effectiveness of the locking device against burglary.

Figure 2 is a schematic diagram 1 of the anti-theft structure of the present creation.

Figure 3 is a schematic diagram 2 of the anti-theft structure of the present creation.

With regard to the structural composition, technical means and efficacy of the present invention, only the examples of the preferred embodiment are further illustrated in the following:

First, as shown in Figures 2 and 3, the structure is mainly provided with a lower card abutting piece (40) at the lower end of the locking piece (30) in the lock (20), and the lower end of the lower card abutting piece (40) The lower clamping piece (40) is further protruded from the lower end of the shaft column (21) with a plug (41), and the plug (41) is provided with an elastic member ( 42), and the rear end of the elastic member (42) is fastened to the inner wall of the lock (20), and the lower retaining piece (40) forms a receiving portion with respect to the position of the key hole (25) ( 44), and the lower end of the lower card (40) has a latching end (43) extending upwardly, and a latching end (43) The card is placed between the teeth (23) of the main latch body (22); that is, when the key (50) is inserted into the key hole (25) and rotated, the key (50) can press the lower card (40) Rotating the shaft (21) as the axis, and causing the snap end (43) to disengage from the tooth (23), and simultaneously pushing the locking piece (30) to move upward and the main latch body (22) The teeth (23) are used to cause the main latch body (22) to be convex or contracted to cause unlocking or latching, and the lower tab (40) can be automatically reset by the elastic member (42).

Thus, if you want to use the foreign object to disturb the tamper lock (30), you need to simultaneously disengage the lower zipper (40) to disengage the snap end (43) from the plucking (23) and slam the lock (30). The main latch body (22) card body (24) is located on the gate (31) of the locking piece (30), and simultaneously moves the main latch body (22) to move inward, which will greatly increase the difficulty of stealing. In order to improve the effectiveness of the lock against burglary.

The above description is only a preferred embodiment of the present invention, and it is still within the scope of the present invention to have equivalent changes made by those skilled in the art in accordance with the present invention and well-known changes of those skilled in the art.
