Description

A kind of plug-type Aluminum plastics door and window security protection lock

Technical field:

The utility model relates to a kind of security protection lock that is installed on the plug-type Aluminum plastics door and window fan, belongs to a kind of of lock.

Background technology:

Existing plug-type Aluminum plastics door and window, close between two bars of back and locked by being installed in bar middle woodruff key or core-pulling lock, make and be in the disjunctor state between two bars, can not slide relatively, reach the purpose of locking, when two bars are in opening, just break away from the disjunctor state between two bars, can slide relatively, make and to be spurred arbitrarily between two fans and enlarged the open gap, make child can produce the tragedy of falling down from the building because the gap is arbitrarily enlarged, the thief is also enlarged the theft of chamber, people from gap because of bar easily voicelessly spurs easily, bring safe going up and psychological hidden danger and worry to people, but existing a kind of patent No. is " 200520082598.X " at present, name is called the patented product of " a kind of Multiple locking point safety plastic-aluminum sash lock ", from the design shape of product and manual thereof the above, solved the problems referred to above.But in fact, its product design exists very big defective, does not solve practical problem well.Reason is as its " 200520082598.X " product structure shown in Figure 1, height at the following horizontal edge that pairing another fan sash of this product is installed is certain, the glazing rebate K1 that certain depth is arranged in interior, be embedded with glass in the groove, as shown in Figure 2, the only lockhole that bores in order to cooperate lock pin, just glazing rebate K1 should avoided, end lockhole such as K2 at glazing rebate to bore down, end lockhole and have only this just can not get into glass below position, just can't bore and end lockhole otherwise just will inevitably get into glass such as K3 and K4 position, as shown in Figure 3, also just make this lock to install, can't realize its function, ineffective.Reach the installation purpose that does not get into glass, lock body is moved down, be positioned as close to the slide rail K5 on window frame base, the base 10 of existing " 200520082598.X " patented product is provided in a side of the two sides of the lock housing of existing lock body, as shown in Figure 1, its base 10 has fixedly played the fixedly effect of lock body by screw when mounted, but because base 10 designs are in the two sides of lock housing, base position on one side must be arranged between lock body and slide rail, lock body can't be moved down, base 10 as shown in Figure 3, end lockhole K3 or K4 if bore like this, just got to the on glass of glazing rebate, caused the glass fragmentation, so this defective has caused " 200520082598.X " patented product can't install on a lot of windows.

Summary of the invention:

The purpose of this utility model is to solve the deficiency of prior art, and a kind of " a kind of plug-type Aluminum plastics door and window security protection lock " that can be widely used is provided.

The utility model is can cross following technical scheme to realize:

The utility model " a kind of plug-type Aluminum plastics door and window security protection lock ", it is made up of lock housing 1, lock core body 2, spring 3, as shown in Figure 4.The inner chamber of lock housing 1 is a cylindrical cavity, and an end is for containing the circular open 1-1 of lock core body 2, and the other end is the plane of a sealing, and the central part on the plane is provided with a lockpin hole 1-2.Lock core body 2 is a cylinder, its end is provided with keyhole 2-1, the other end is provided with a lock pin 2-2, on lock pin, be with spring 3, when key being inserted lockpin hole 2-1 twisting, lock core body is outwards ejected under the effect of spring 3 this moment, in the cylindrical cavity of just indentation lock housing of lock pin 2-2, state goes out of lock.

Technical characterstic of the present utility model is, not to establish firm banking in the two sides of lock housing, but establish firm banking at the two ends of lock housing, promptly extend outward one section transverse slat 4 to circular open 1-1 one end along lock housing body 1, at the other end along the plane that has lockpin hole 1-2, towards extending another section riser 5 vertically downward with extension transverse slat 4 direction at an angle of 90, extended transverse slat 4 and the riser 5 common firm bankings of forming lock.The effect of transverse slat 4 and riser 5 is with screw lock body to be fixed on the lower end of sash by being located at the fixing hole gone up separately, at least respectively establishes a fixing hole on transverse slat 4 and the riser 5.

The advantage of firm banking design at the lock housing two ends is, the one, eliminated the obstacle of lock body side, lock body is had can be to the as close as possible space of the track on window frame base, just can make the lockhole that ends on the corresponding sash that the space that moves down is also arranged, avoided the glazing rebate on sash base, it is on glass that lockhole can not got into again, shown in Fig. 6,7.The 2nd, because riser 5 and lock housing at an angle of 90, have formed the turning stuck point, make riser 5 play location and stabilization to lock body.The 3rd, reduced the lock housing volume, conservation.
