Abstract

The present invention relates to an anti-pry lock assembly for a pin tumbler lock, in the aspect of structural design, its key-cuts portion mainly consists of three longitudinal ridge ribs, an upper transverse rib and a lower transverse rib for connecting the ridge ribs, wherein the upper transverse rib is connected to the upper ends of the front two ridge ribs, and the lower transverse rib is connected to the lower ends of the rear two ridge ribs, to accordingly form a square wave structure; in addition, the pin tumbler lock main body consists of a lock body portion and a cylinder structure, the cylinder has a bored keyhole extending inwardly, with its interior being reserved with cylindrical holes perpendicular to the keyhole. Furthermore, cylindrical pins are disposed inside the cylindrical holes, and a cylinder long hole is extendedly disposed on top of the cylindrical pins in the lock body portion, and sequentially provided with a column and an elastic member; wherein the keyhole located on both sides of the cylindrical pins is a solid structure composed of a closed edge and a blocking edge, namely, there is no clearance space on both sides of the cylindrical pins in the keyhole; and the ridge ribs in the key-cuts portion that are connected by the lower transverse ribs can be inserted by the inner end of the keyhole; so that the user can only use an exclusive key having the square wave key cuts portion to lift the front end of the cylindrical pins for unlocking the lock, thereby to effectively prevent a lockpicking state in which the clearance on both sides of the cylindrical pins are directly inserted therefrom, so as to improve the effectiveness of antitheft.

Description

Bead lock anti-smashing lock set

The invention relates to a bead lock anti-smashing lock set, which is mainly arranged through a position of a cylindrical bead in a lock hole and a bead lock body, so that a solid structure of a closed edge and a shielding edge is formed on both sides of the cylindrical bead at the lock hole. And with the corresponding key with the square wave lock tooth part, it can effectively prevent the gap shackle, and improve the anti-theft effect of the lock.

According to the current general bead lock structure, as shown in Figures 1 and 2, the bead lock body (10) has a lock head (11) structure, and the lock head (11) is provided with a keyhole (13). The bead lock body (10) and the lock head (11) are provided with a plurality of cylindrical beads (15), a top post (16) and a spring (17) set perpendicular to the keyhole (13); The specially configured key (12) is inserted into the keyhole (13), and the cylindrical bead (15) is propped up through the bead groove (18) on the key (12), so that the cylindrical beads (15) and the lock head ( 10) When the edge is flush, the lock (11) can be rotated to control the opening and closing of the lock.

However, the conventional keyhole (13) and the cylindrical bead (15) are arranged to have a gap (14) on both sides of the cylindrical bead (15), and the gap (14) is shackled by the thief. The channel, and thus the loss of the main purpose of the lock, should be addressed to improve the person.

In view of the shortcomings of the conventional bead lock on the structure, the inventor developed the present invention based on years of experience in the manufacture of related products, and the main purpose of the invention was developed. It is through a key of the square wave-shaped tooth lock, with the position of the cylindrical bead in the lock hole and the bead lock body, so that the cylindrical bead forms a solid structure with no gap at the lock hole, so as to block Break the space of the shackles and achieve excellent anti-smashing effect.

With regard to the structural composition, technical means and efficacy of the present invention, only the embodiments of the present invention will be further described in detail with reference to the preferred embodiments. First, please refer to the keys of the present invention as shown in Figures 3 and 4. The locking tooth portion (22) is mainly composed of three longitudinal ribs (23) and two connecting ribs (23) and lower transverse ribs (24) (25), wherein the upper transverse ribs (24) are connected At the upper end of the front two ridge ribs (23), and the lower transverse ribs (25) are joined to the lower ends of the rear ridge ribs (23), thereby forming as " "The square wave structure."

Next, as shown in Figures 3 and 5, the bead lock body (20) of the present invention is mainly composed of a lock body portion (30) and a lock head (40) structure, and the lock head (40) is provided with an inward extension. The keyhole (41) is dug and has a plurality of cylindrical holes (42) disposed perpendicularly to the lock hole (41), and the cylindrical hole (42) is provided with a cylinder of different length and length a bead (34); further, the cylindrical hole (42) is extended inside the lock body portion (30) and has a plurality of cylindrical long holes (31), and the cylindrical long hole (31) is provided with a top column (32) and An elastic member (33); and the locking hole (41) on both sides of the cylindrical bead (34) forms a solid structure of a closed edge (44) and a shielding edge (43), that is, a cylindrical bead (34) There is no gap space between the two sides of the lock hole (41).

Furthermore, in use, the ribs of the lock (21) locking portion (22) connected by the lower transverse ribs (24) are inserted through the inner end of the locking hole (41), that is, the user can only use the exclusive lock. The key (21) of the head (40) is unlocked by the front end of each cylindrical bead (34), so as to effectively block the foreign matter from directly extending into the yoke from the gap on both sides of the cylindrical bead (34) The situation.

While only the preferred embodiments of the prior invention are described herein, and are illustrated by way of illustration of the best mode in which the present invention can be practiced, several of the details can be modified with a number of distinct points. Therefore, the above illustrations and descriptions are illustrative and not limiting.
