Abstract

The utility model relates to a billiard of a billiard idle-motion locking head. One side of the billiard is a plane, and the other side is an arc surface, which forms a semi-circular or a large semi-circular column; the plane of the billiard is provided with one or more recesses. The billiards can be cooperated with other components of the billiard idle-motion locking head to realize the functions of the lock such as locking, unlocking, idle motion, etc., so that the lock is characterized in that the lock is free from being unlocked while the lock core can be randomly rotated when a key of other locks is inserted, thereby greatly improving the anti-theft performance.

Description

A kind of pellet shot from a slingshot of marble idle rotation lock head

Technical field:

The utility model relates to a kind of pellet shot from a slingshot of cylinder lock, especially the pellet shot from a slingshot of marble idle rotation lock head.

Background technology:

Common cylinder lock locks by pellet shot from a slingshot, and each the pellet shot from a slingshot group in the lock is formed by two pellets shot from a slingshot, and every pellet shot from a slingshot is a cylinder.This pellet shot from a slingshot can not be applicable to has increased lost motion functionality, and the marble idle rotation lock head that locks by on-of pin.

Summary of the invention:

The purpose of this utility model provides a kind of new pellet shot from a slingshot, and this pellet shot from a slingshot can be applicable to has increased lost motion functionality, and the marble idle rotation lock head that locks by on-of pin.

The technical solution of the utility model is: one side is cambered surface, and another side is semicircle or more than half cylindrical pellet shot from a slingshot on plane, and its plane has one or more notch.

Pellet shot from a slingshot of the present utility model can match with other parts of idle-run lock head, makes that this lock is realized unblanking, functions such as locking and idle running

The beneficial effects of the utility model are: it can match with other parts of idle-run lock head, realize functions such as the unblanking of this lock, locking and idle running, make this lockset have non-lock key to insert, lock core can rotate arbitrarily and lock the characteristics that are not unlocked, and theftproof greatly improves.

Description of drawings:

Below in conjunction with accompanying drawing the technical solution of the utility model is described further.

Fig. 1 is the structural representation of first embodiment of the utility model pellet shot from a slingshot.

Fig. 2 is the structural representation of second embodiment of the utility model pellet shot from a slingshot.

Fig. 3 is the structural representation of the 3rd embodiment of the utility model pellet shot from a slingshot.

Fig. 4 is the structural representation of the 4th embodiment of the utility model pellet shot from a slingshot.

Fig. 5 is the cross sectional representation that the marble idle rotation lock head of first embodiment pellet shot from a slingshot of the utility model has been installed.

The specific embodiment:

Shown in Figure 1 is first embodiment of the utility model pellet shot from a slingshot, and this embodiment pellet shot from a slingshot is to be cambered surface 2 by one side, and another side is semicircle or the large semicircle cylinder that plane 3 constitutes, and 3 have one or more notch 4 on the plane.It is applicable to double marble idle rotation lock head shown in Figure 5, this tapered end is by housing 7, with be enclosed within rotating clutch cores 8 in the housing 7, lock core 9 formations such as grade, cylindrical lock core 9 is enclosed within clutch core 8 interior clutch cores 8 cylindraceous and is the main body of unblanking, lock core 9 has two row's pellet shot from a slingshot holes 10 vertically, establish a pellet shot from a slingshot spring 11 in every hole, the utility model pellet shot from a slingshot 1, vertically have secondary bullet groove 12 perpendicular to pellet shot from a slingshot hole 10, in establish secondary pellet shot from a slingshot 13, the inner of secondary pellet shot from a slingshot 13 is pressed on the plane 3 of the utility model pellet shot from a slingshot 1, have clutch cotter way 14 at clutch core 8 corresponding to secondary bullet groove 12 places, in establish on-of pin 15, have lock slots 16 at ground housing 7 corresponding to clutch cotter way 14 places, be provided with pellet shot from a slingshot hole 17 in the groove, insert return pellet shot from a slingshot 18 and return pellet shot from a slingshot spring 19.When unblanking, under the effect of key 20, the notch 4 of all the utility model pellets shot from a slingshot 1 is all to chief and vice pellet shot from a slingshot 13, on-of pin 15 and secondary pellet shot from a slingshot 13 move together under the effect of return pellet shot from a slingshot 18 and return pellet shot from a slingshot spring 19, the inner of secondary pellet shot from a slingshot 13 enters the notch 4 of the utility model pellet shot from a slingshot 1, and lock core 9 is inserted in the inner of on-of pin 15, is stuck between lock core 9 and the clutch core 8, lock slots 16 is withdrawed from the outer end of on-of pin 15, at this moment twists key 20 and just can will lock unlatching by lock core 9 drive clutch cores 8.During locking, extract key 20, the utility model pellet shot from a slingshot 1 moves under the effect of spring 11, its notch 4 departs from secondary pellet shot from a slingshot 13, the top is compeled secondary pellet shot from a slingshot 13 and is moved, secondary pellet shot from a slingshot 13 promotes on-of pin 15, originally the on-of pin 15 that was stuck between lock core 9 and the clutch core 8 withdraws from lock core 9, lock core 9 is separated with clutch core 8, and lock core 9 is in idling conditions, and the lock slots 16 that the outer end of on-of pin 15 enters housing 7 is stuck between housing 7 and the clutch core 8, form lock-out state, at this moment, non-lock key or other foreign matters insert can rotational lock core 9, but this lock is not unlocked.

Shown in Figure 2 is second embodiment of the utility model pellet shot from a slingshot, and the difference of it and first embodiment shown in Figure 1 is as follows: be provided with limited step 5 at afterbody one end on the plane 3 of the utility model pellet shot from a slingshot 1.

Fig. 3, shown in Figure 4 be the 3rd embodiment of the utility model pellet shot from a slingshot, it and Fig. 1, difference embodiment illustrated in fig. 2 are as follows: afterbody one end at the utility model pellet shot from a slingshot 1 is provided with spring fixed column 6.
