Abstract

The utility model discloses a lock of an aluminum plastic window, and belongs to a lock installed on aluminium alloy and plastic steel sliding doors and windows. The utility model is composed of a locking head 1, a lock core 2, a key 3 and a lock plug 6. The utility model is characterized in that the end part of the lock core 2 is provided with a thumb wheel 12 which is connected with the lock core to form a body, the lock plug 6 is in a shaft shape and transversely penetrates through the end part of the lock head, and a notch which is engaged with and makes contact with the thumb wheel 12 is arranged on the contact surface of the shaft-shaped lock plug and the thumb wheel 12. Because after the lock is installed on the plastic-aluminum window, the lock needs the key to control the opening and closing of the aluminum plastic window, and the utility model can thoroughly overcome the defects of a rotary hanging hook. The utility model has the advantages of safe, theft prevention, reliable performance, convenient use, compact structure and low cost.

Description

The plastic-aluminum sash lock

Technical field:

The utility model relates to a kind of plastic-aluminum sash lock, belongs to the lock that is installed on aluminium alloys and the plastic-steel sliding window.

Background technology:

What generally install on the existing plastic-aluminum sliding door and window is a kind of rotary hook, and its utilizes hook and the relative rotary motion of ending jam plate to realize unlatching, locking control to aluminium plastic window.Rotary hook theftproof performance is poor, and the security hidden trouble of existence is more, and is of common occurrence by the incident of Aluminum plastics door and window burglary in daily life.There are following two problems in rotary hook: the one, hook, end that jam plate easily comes off, easily brittle failure, and directly cause linking up with locking and lost efficacy; The 2nd, under the effect of certain external force, small deflection flexural deformation can take place in the plastic-aluminum window frame in the horizontal direction, makes the slit that produces between the two-light frame about 5mm, and the existence in slit makes the very easy disengaging of hook end jam plate, causes linking up with disabler.

Summary of the invention:

The technical problems to be solved in the utility model is, designs a kind of safe antitheft, dependable performance, easy to use, compact conformation, plastic-aluminum sash lock that cost is low.

The structure of this plastic-aluminum sash lock is, it is by tapered end 1, lock core 2, key 3 and locking bolt 6 are formed, its special character is, establishes a thumb wheel of fixedlying connected with it 12 in the end of lock core 2, and locking bolt 6 is for crossing the axle shape in the tapered end end, on 12 contacted of this shape locking bolt and thumb wheels, establish and notches that thumb wheel 12 coincide and touches mutually.

A kind of embodiment preferably of the utility model is that the left end position or the right-hand member position of axle shape locking bolt notch place face are the plane.Like this, can cause under the situation of locking bolt distortion, can under the situation of motionless tapered end, directly make and be decreased locking bolt disengaging tapered end, and change new locking bolt because of misoperation, easy to maintenance.

The utility model another kind embodiment preferably is, thumb wheel 12 is three tooth thumb wheels, and this thumb wheel can more effectively guarantee the intensity of its tooth, increases reliability, and the thumb wheel tooth is carried out the transition on the locking bolt plane, makes locking bolt and tapered end convenient separation.

Operating principle: utilize the straight reciprocating motion of the control locking bolt that rotatablely moves of lock core thumb wheel.One, opening process: insert key 3, the dextrorotation three-sixth turn, lock core 2 is with key 3 rotations, thumb wheel 12 on the lock core 2 drives the locking bolt 6 that is engaged with and withdraws from window frame lockhole (as shown in Figure 2), at this moment, lock is in opening, and two fan windows can be done relative slip to realize unlatching on slideway.Two, locking process: close window to determining the position, insert key 3, be rotated counterclockwise 360 degree, lock core 2 is with key 3 rotations, thumb wheel 12 on the lock core 2 drives the locking bolt 6 that is engaged with and inserts window frame lockholes (as shown in Figure 3), and at this moment, two window frames by the firm bolt of locking bolt together, can not on slideway, do relative slip, realize locking.

Because the utility model has adopted above technical solution, makes it compared with prior art, has characteristics easy to use, stable performance, as: key dextrorotation three-sixth turn can be finished unlatching, is rotated counterclockwise 360 degree and can finishes locking; This is locked in unlatching, locking states all can plug and unplug key; In unlatching, locking process, can not plug and unplug key.Safe and reliable, locking bolt 6 crosses tapered end 1 and is meshed with the lock core thumb wheel, and tapered end 1 is vertical mutually with the axis of locking bolt 6, like this, even the fixed screw 13 of tapered end 1 (with reference to figure 5) becomes flexible, has come off, tapered end 1 still by the firm bolt of locking bolt 6 on window frame, can not come off thereupon, lose efficacy.

The drawing explanation:

The structural representation of an embodiment of Fig. 1-the utility model

Fig. 2-lock shown in Figure 1 is in the user mode reference diagram of opening

Fig. 3-lock shown in Figure 1 is in the user mode reference diagram of locking states

The locking bolt of Fig. 4-lock shown in Figure 1 and thumb wheel engagement figure

The positive user mode reference diagram of Fig. 5-lock shown in Figure 1

The specific embodiment:

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.

Embodiment 1, with reference to figure 1-Fig. 5.Find out that by Fig. 1 the concrete structure of this lock is by tapered end 1, lock core 2, key 3, following pellet shot from a slingshot 4, lock core pin 5, locking bolt 6, locking ball 7, retainer spring 8, pellet shot from a slingshot hole mounting 9, marble spring 10, last pellet shot from a slingshot 11 and thumb wheel 12 are formed.Thumb wheel 12 is three tooth thumb wheels, and here, it and tapered end 1 are integral structures.Locking bolt 6 is the axle shape vertical with tapered end 1, and touches mutually by notch and thumb wheel 12 are identical, and the left end position of locking bolt notch place face is plane.In the time of can seeing that by Fig. 2 lock is positioned at the window frame back side, be in the structure of opening; In the time of can seeing that by Fig. 3 lock is positioned at the window frame back side, be in the structure of locking states; Can see the lock that is positioned on the window frame back side by Fig. 4, analyse and observe under the state structure that its locking bolt 6 is meshed with thumb wheel 12; What see by Fig. 5 is the structure that is positioned at the positive lock of window frame.This lock is easy to maintenance, reason is that the left end position of locking bolt notch place face is plane, and thumb wheel 12 is three tooth thumb wheels, when key rotates to definite position, when making two teeth of three tooth thumb wheels 12 be on as shown in Figure 4 locking bolt 6 planes, locking bolt 6 can be realized under the effect of external force and effectively the separating of thumb wheel 12 smoothly.Like this, in use as because of misoperation causes locking bolt 6 gross distortions, and then cause lockset to open and close also need not to dismantle tapered end when smooth,, extract old locking bolt, replace with new locking bolt and get final product as long as key is rotated to definite position.The principle of its unlatching, locking as previously mentioned.

In like manner, according to the technical solution that the utility model provides, can also provide with embodiment 1 and compare, the structure of other parts is constant, only thumb wheel 12 is four tooth thumb wheels, five tooth thumb wheels, six tooth thumb wheels ... multiple tooth thumb wheel, the notch of locking bolt 6 become the embodiment of the structure that matches with it thereupon.Perhaps, the structure of comparing other parts with embodiment 1 is constant, and only locking bolt 6 for not with the embodiment on plane.

The lock of this form of structure goes on the convenient various windows of installing, the door.
