Description

Lock

The utility model relates to a kind of novel tapered end, belongs to the lockmaking technical field.

Be locked in people's the life and be absolutely necessary, door, drawer, safety cabinet, combination lock etc. all be can't do without the device-lock of a key.The kind of lock is a lot, as padlock, many tongues safety lock, coded lock etc.On opening-closing structure and principle, be mainly cylinder lock and the concavo-convex combination lock of splitting.But which kind of lock all will have the key that matches with it, opens different locks with different keys.So everybody has a lot to carry by key, just in case lose one or key lock will be occasioned a great deal of trouble in the room.

The utility model aims to provide a kind of number ball lock head that does not need key, can be used for all kinds of locksets.

The three parts that are configured with of the present utility model:

One. core, closing cylinder portion in the heart have n horizontal circular groove of a row to do the spring marble chamber, following abbreviation pellet shot from a slingshot chamber.N is not less than 3 positive integer (down together).Each pellet shot from a slingshot chamber outwards is placed with one on spring, one of conehead pellet shot from a slingshot of square pellet shot from a slingshot in proper order from the lining.Core top has alignment pin and decides arc groove, is used for core is connected with lock body, prevents that core from coming off from lock body.The core top can be provided with the driving member that is communicated with dead bolt, gets final product with the corresponding component structure that has lockset.Projection or screw or the pin-and-hole that handle is installed arranged at the core bottom, connects one handle; Or core and handle are as one.

Two. rotate letter disk, letter disk is the garden ring-type, can be an annulus, can be one by the internal and external double-circular nail also.The letter disk number is n.Mint-mark has ten digital codes of 0-9 on the face of the outer garden of outer shroud, evenly is distributed as suitablely, and interior ring the inside and the corresponding position of outer shroud character code are fluted, and depth of groove matches with corresponding core pellet shot from a slingshot length.For a tapered end, have only an outer annular recess to match on each letter disk with corresponding pellet shot from a slingshot length, when this specific groove part on each letter disk was aimed at corresponding pellet shot from a slingshot simultaneously, core can rotate in lock body, drove dead bolt, and lockset promptly leaves.

Accurately convenient in order to check the number, can on the character code position, alignment mark be set.For the ease of night or dark place check mark establishing the salient point marking at " 0 " character code place of each letter disk, groove rubs to collide slight vibration, and character code of revolution can be by feel to once vibration, and pellet shot from a slingshot and outer annular recess grind the spy sidewipe collision slight vibration, and character code of revolution can

Three. lock body, between core and letter disk is lock body, corresponding to the perforate of core pellet shot from a slingshot chamber place, is convenient to contacting of pellet shot from a slingshot and letter disk inner ring surface groove.With detent corresponding position, core top alignment pin is being arranged; Lock body can be designed to various forms according to product needed, as padlock, lock, safety cabinet lock, built-in lock etc.

The size of above each several part and connection can be with reference to existing locksets.Lettered dial tightly is enclosed within outside the lock body, be advisable rotating easily flexibly, during lockmaking outside lock body letter disk up and down Ying You prevent the facility that letter disk breaks away from, as convex tendon, garden ring etc.Core matches with the lock body size, rotating certain angle therein, and institute's gyration is consistent with the radian that core top alignment pin is decided groove.Ordinary circumstance is advisable for radian 20-90 °.

Fig. 1 is that the utility model tapered end is in the structural representation when opening, wherein, and 1. core, 2. pellet shot from a slingshot chamber, 3. spring, 4. square pellet shot from a slingshot, 5. conehead pellet shot from a slingshot, 6. letter disk, 7. letter disk inner ring surface groove, 8. the core alignment pin is decided groove, 9. alignment pin, 10. lock body, 11. letter disks are prevented knocking over, 12. core turning handles.

Fig. 2 is the vertical view of Fig. 1 tapered end, the same Fig. 1 of number in the figure.

Fig. 3 is that the core alignment pin is decided the groove vertical view, the same Fig. 1 of number in the figure.

Fig. 4 is the structural representation of the utility model tapered end when being in closure.Wherein, ring in 13. letter disks, 14. letter disk outer shrouds.

Fig. 5 is the vertical view of Fig. 4 tapered end, the same Fig. 4 of number in the figure.

Fig. 6 is the utility model tapered end part letter disk external surface schematic diagram.Wherein, 15, alignment mark, 16. salient points.The same Fig. 1 of other labels.

Fig. 7 is that the utility model tapered end is used for different lockset schematic diagrames.Wherein, a. padlock, b. lock, c. door lock, the same Fig. 1 of number in the figure.

Embodiment 1, shown in Figure 5 as Fig. 1 Fig. 2, n=4, row's pellet shot from a slingshot chambers 4,4 letter disk garden rings, each figure disc external surface has ten numbers of 0-9, and the groove of ten different depths is arranged on the corresponding letter disk inner ring surface, and one of them depth of groove matches with corresponding pellet shot from a slingshot, the two is on time, the taper pellet shot from a slingshot just in time is arranged in groove and lock body wall, and just in time when pellet shot from a slingshot was indoor, this a pair of pellet shot from a slingshot did not hinder core to rotate to square pellet shot from a slingshot.When the particular groove of four letter disks was alignd corresponding pellet shot from a slingshot, core just can twist.It is 30 ° that alignment pin is decided the groove radian, also rotatable 30 ° of cores.This tapered end can make 10 ⁴The lock of individual jack per station.

Embodiment 2, and is shown in Figure 5 as Fig. 3 Fig. 4, and letter disk is fixed as one by inside and outside two annulus, and ten numbers of 0-9 are arranged on the outer ring outer surface, and corresponding ten grooves are arranged on the interior ring inner ring surface.Core top alignment pin is decided 60 ° of grooves, and other structures are with embodiment 1.

Embodiment 3, and as described in embodiment 2, that different is n=5, can make 10 ⁵The lock of individual jack per station.

The utility model tapered end need not worn key, the number of an alignment settings, and the twisting handle can be unblanked, and is safe and reliable.It is also very convenient to unblank night.Make simply, be beneficial to suitability for industrialized production.N the letter disk in n pellet shot from a slingshot chamber can be made into 10 ⁿThe cylinder lock of individual jack per station.
