Abstract

A ball lockset structure is characterized by comprising a lock tongue (2), a ball (3), and a locking block (4), wherein the lock tongue (2), the ball (3) and the locking block (4) are arranged in a lock body shell (1), the lock body shell (1) is provided with an inclined plane groove (11) and an inserting hole (12), the ball (3) is arranged in the inclined plane groove (11) and connected with one end of the locking block (4), the lock tongue (2) is inserted in the inserting hole (12) and limited by the ball (3), and when the lock tongue (2) moves up and down, pushing force is generated to the ball (3). The ball lockset structure is simple in structure and convenient to produce.

Description

A kind of cylinder lock set structure

Technical field

The utility model relates to a kind of lockset, in particular, relates to a kind of cylinder lock set structure.

Background technology

At present, common lock structure more complicated on the market, component are many, cost is high.

The utility model content

The purpose of this utility model is for a kind of cylinder lock set structure is provided, and it is simple in structure, good reliability, cost of production are low.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of cylinder lock set structure is characterized in that: comprise the dead bolt 2, pellet 3, the latch 4 that are assemblied in the lock body shell 1; Lock body shell 1 is provided with surface groove 11, jack 12, and pellet 3 is assemblied in the surface groove 11 and links to each other with an end of latch 4, and dead bolt 2 inserts in the jack 12 and is subjected to the spacing of pellet 3, can produce thrust to pellet 3 when dead bolt 2 moves up and down.

The spheroid of described pellet 3 for rolling.

The limit method of 3 pairs of dead bolts 2 of described pellet is not limited to following situation: dead bolt 2 is provided with breach 21, and pellet 3 matches with breach 21; Breach 21 can also be semi-spherical shape.

In order better to save the space, the end that latch 4 links to each other with pellet 3 is ramp structure.

Consider that dead bolt 2 is easy to extract and inserts lock body shell 1 in the actual use, can be provided with arc end at the top of dead bolt 2.

Because adopt said structure, thereby improved safety, the reliability of lockset, and simple in structure, exquisite small and exquisite, be fit to large-scale promotion and application.

Description of drawings

Fig. 1 is that dead bolt inserts in the lock body shell lock-out state generalized section;

Fig. 2 is that dead bolt is extracted outside the lock body shell, the unlocking condition generalized section.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

As shown in Figure 1, for dead bolt 2 inserts in the jack 12 of lock body shell 1, the lock-out state schematic diagram; When latch 4 was subject to External Force Acting and moves up, the top of latch 4 promoted pellet 3 and upwards moves surface groove 11 in, and pellet 3 is matched with breach 21 on the dead bolt 2, and dead bolt 2 is subject to the spacing of pellet 3 and can't moves up and down, and maintains the lock status.

As shown in Figure 2, extract outside the jack 12 of lock body shell 1 the unlocking condition schematic diagram for dead bolt 2; When latch 4 is subject to External Force Acting and moves down, the resistance of 4 pairs of pellets 3 of latch disappears, at this moment, outer bound pair dead bolt 2 applies pulling force upwards, can promote pellet 3 when dead bolt 2 moves upward moves downward, simultaneously, because pellet 3 residing groove positions are surface groove, and the spheroid of pellet 3 for rolling, so the thrust that produces when pellet 3 is moved upward by self gravitation and dead bolt 2 is rolled downwards, at this moment, pellet 3 is no longer spacing to dead bolt 2, dead bolt 2 can be extracted the jack 12 on the lock body shell 1 smoothly, reaches the purpose of unblanking.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim; Should be pointed out that for a person skilled in the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these distortion and improvement all belong to protection domain of the present utility model; Therefore, all equivalents and modifications of doing with the utility model claim scope all should drop within the protection domain of the utility model claim.
