Abstract

The utility model relates to a mechanical leaf lock with wavy key teeth. The mechanical leaf lock with wavy key teeth is characterized in that the surface of a key (1) is provided with wavy teeth, a lock (9), a lock core (8), a leaf (5), a slide block (6), dust prevention assemblies (2), (3), (4), (10), etc. Since a grade of slope is arranged at a groove in opening state in the leaf groove of the central hole of the lock (9), no key is needed when closing, and the leaf (5) contracts in the lock core (8) automatically on the grade of slope of the lock (9) via revolving a knob (4) and rotating the lock core (8). The lock has the advantages of automatic closing, beauty, durable use, dust prevention, theft prevention, compact and reasonable structure, low fabrication cost, etc.

Description

Automatically close locking head

1, technical field:

The utility model " closes locking head automatically " and relates to a kind of self-locking mechanical type tapered end.

2, technical prospect:

The tapered end major part of Xiao Shouing all will be made locking action with key in the market, and pellet shot from a slingshot exposes, and is easy to be entered by the dust rainwater, causes damage easily, is difficult to satisfy the easy durable pursuit of modern really.I once designed in the design of the patent No.: ZL01271507.7, ZL01243057.9, ZL02230652.8 etc. and mentioned dust reduction capability.Therefore how to utilize advantage on the tapered end to make the tapered end can be in use more convenient more durable, and can without key can lock lock core and structure simpler attractive in appearance and theftproof is strong.The utility model has successfully solved the problems referred to above.

3, summary of the invention:

The purpose of this utility model provides the self-locking mechanical type tapered end of a kind of energy, it is provided with corrugated tartar on the surface of key, the effect that utilizes the page or leaf sheet outwards to eject, on the page or leaf film trap of tapered end endoporus, wherein on the page or leaf film trap of opening, be provided with gradient, make it when closing as long as rotary locking cylinder, the page or leaf sheet is just with in the automatic retraction lock core of variation of gradient, thereby reach self-locking function, and the transmission pin is housed, slide block is housed at the tapered end afterbody at the lock core afterbody.Pin transmission by the lock core afterbody moves up and down slide block to reach locks or function that transmission is closed.And have additional the combination of roller type spoon door, thus realized making this lock head structure more reasonable, attractive and durable, easy to use, the door that can be widely used in various locksets, automobile gear lock and drawer and indoor and outdoor is gone up use.

The utility model is achieved by the following scheme: form complete lock head structure by key, lock core, tapered end, page or leaf sheet, trundle, slide block and the dustproof composite member of spoon door etc.When inserting key, outside two side shiftings of roller bearing on the spoon door, key is inserted smoothly, in the position retraction lock core of page or leaf sheet according to tartar lock core is rotated flexibly, transmission pin by the lock core afterbody slides up and down slide block simultaneously, and after key was extracted in a page or leaf film trap position that goes to opening, the page or leaf sheet moved laterally by the effect of spring, and spoon door roller bearing moves to the inside by the effect of spring simultaneously, thereby reaches the effect of sealed key hole.

4, description of drawings:

Fig. 1 is a configuration diagram of the present utility model.

Fig. 2 is that the A-A of Fig. 1 makes up diagrammatic sketch to the dustproof spoon door of roller bearing.

Fig. 3 is that the C-C of Fig. 1 is to the slide block movement diagrammatic sketch.

Fig. 4 be the B-B of Fig. 1 to lock core spacing and page or leaf sheet diagrammatic sketch.

Fig. 5 is the diagrammatic sketch after Fig. 4 rotates.

5, the specific embodiment:

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, it comprises: in the hole groove that lock core (8) front end of at first roller bearing (3) and spring (10) being packed into is provided with, refill upper envelope (2) and knob (4), with pin (11) and lock core (8) just riveted forms complete dustproof combination.Stamp pin (7) in the default hole of lock core (8) afterbody, be fitted into a page sheet (5) then at lock core (8) spring (12) of packing into, and by the tartar of key (1).At the chute of tapered end (9) slide block (6) of packing into, the lock core (8) that will prepare page sheet is more packed in the hole of tapered end (9), the pin (13) of packing into then is fixed on lock core (8) in the tapered end (9) and can rotates flexibly, has just formed complete automatic locking tapered end by above-mentioned steps.

Claims

1, closes locking head automatically: the mechanical lock head that is a kind of page of chip.It comprises: key (1), lock core (8), page or leaf sheet (5), slide block (6), pin (7), tapered end (9) and dustproof composite member (2), (3), (4) and other pin spring etc. are formed complete automatic pass locking head.

2, assembly part according to claim 1 is characterized in that dustproof composite member by shown in Figure 2, loads onto roller bearing (3) and the dustproof built-up section of big envelope (2) composition at lock core (8) front end.

3, according to claim 1, it is characterized in that tapered end (9) is provided with the page or leaf film trap of chute and centre bore, be provided with gradient, press Fig. 4, shown in Figure 5 in a direction of symmetry, make page sheet when rotational lock core (8), can be under the effect of gradient in the automatic retraction lock core.

4, according to claim 1, it is characterized in that slide block (6) has the hole groove, by being contained in pin (7) transmission of lock core (8) afterbody,, make slide block locate to slide up and down at tapered end (9) by shown in Figure 3.
