Public building door window antitheft hinge can effectively solve the problems, such as that Theft-proof hinge causes crack between a door and its frame excessive.
Its technical solution solved is to include by slot, the first positioning plate, and offers the second positioning plate composition of sliding slot
Door chain ontology；Vertical fixed plate is installed on the second positioning plate；Offered on the leading flank of fixed plate it is multiple up and down according to
The rectangular location hole of secondary arrangement, the inside of fixed plate are equipped with cavity, are placed with riser in cavity, the trailing flank of riser and cavity it
Between multiple pressure springs are installed；One of them in multiple location holes is fitted with the positioning pin of rotation, and the rear end of positioning pin is equipped with positioning
Block, locating piece can be equipped with baffle by location hole, positioning pin middle part after turning an angle.
The utility model is easy to operate, clever structure, low in cost, easily manufactured, safely and effectively, substantially increases antitheft
The safety and convenience of hinge, ensure that the safety of indoor occupant.
Detailed description of the invention
Fig. 1 is the whole main view of the utility model.
Fig. 2 is the stereoscopic schematic diagram of the utility model positioning pin.
Fig. 3 is the left view sectional view of the utility model vertical plate.
Specific embodiment
Specific embodiment of the present utility model is described in further details below in conjunction with attached drawing.
It is provided by Fig. 1 to Fig. 3, the utility model includes and offering the second fixed of sliding slot by slot 1, the first positioning plate 2
The door chain ontology that position plate 3 forms；Vertical fixed plate 4 is installed on second positioning plate 3；It is opened up on the leading flank of fixed plate 4
There are multiple rectangular location holes 5 being arranged successively up and down, the inside of fixed plate 4 is equipped with cavity 6, is placed with riser 7 in cavity 6, erects
Multiple pressure springs 8 are installed between the trailing flank and cavity 6 of plate 7；One of them in multiple location holes 5 is fitted with the positioning pin of rotation
9, the rear end of positioning pin 9 is equipped with locating piece 10, and locating piece 10 can pass through location hole 5 after turning an angle, pacify in the middle part of positioning pin 9
Equipped with baffle 11.
In order to be inserted into positioning pin 9 in location hole 5, the locating piece 10 is fixed simultaneously also to be rectangular
The trailing flank of position block 10 is equipped with rounded corners, convenient for inserting.
In order to preferably realize fixation, the diameter of the positioning pin 9 is less than the aperture of slot 1.
In order to preferably realize blocking, the baffle 11 is circle, and the diameter of baffle 11 is greater than the aperture of slot 1.
In order to preferably fix fixed plate 4, bolt hole 12, while 4 trailing flank of fixed plate are offered in the fixed plate 4
Lower end be equipped with notch 13, convenient for fixed plate 4 and the second positioning plate 3 fixation.
When the utility model is used, it is necessary first to the first positioning plate 2 is fixed on door, then consolidate the second positioning plate 3
It is scheduled on metope, finally fixed plate 4 is fixed on the second positioning plate 3；After three fixes, one end of slot 1 turns at this time
Dynamic to be connected on the first positioning plate 2, the free end of slot 1 is connected with a sliding block, and sliding block can be in the sliding slot of the second positioning plate 3
Sliding.
When in use, it as conventional door chain, needs to place sliding block in the sliding slot with the second positioning plate 3, so
Afterwards, slot 1 is in a kind of state that comparison is loose at this time, and the tightness of slot 1 also determines the size of crack between a door and its frame；Ordinary circumstance
Under, after the first positioning plate 2 and the second positioning plate 3 fix, the relaxed state of slot 1 just cannot be adjusted.
In the present apparatus, it is necessary first to take out the positioning pin 9 being inserted into location hole 5, then need to select as needed
In one of ring in slot 1, positioning pin 9 is inserted into the link, when insertion, since locating piece 10 is side
Shape, it is therefore desirable to it is inserted at a slant, it, can be by the baffle of 9 rear side of positioning pin after allowing the locating piece 10 on positioning pin 9 to pass through slot 1
11 are stopped, and can then select one of them in multiple location holes 5 as needed；Positioning pin 9 is inserted.
After the locating piece 10 of 9 rear end of positioning pin is inserted into location hole 5, locating piece 10 can squeeze shield riser 7 at this time,
Compress the pressure spring 8 of 7 rear side of riser；990 degree of rotary positioning pin are then needed, hinders locating piece 10 by location hole 5
Gear.Simultaneously because squeezing action of the riser 7 to locating piece 10, positioning pin 9 can keep the state.
In this way, pass through the cooperation of positioning pin 9 and location hole 5 at the middle part of slot 1, the relaxation degree of slot 1 will
Change, so as to adjust the size of crack between a door and its frame as needed, anti-anti-skid chain 1 puts in the pincers come by crack between a door and its frame and cuts short.
When not needing the relaxation degree to slot 1 and being adjusted, it is only necessary to which positioning pin 9 is inserted into any one positioning
In hole 5, prevent positioning pin 9 from losing.
The present apparatus is easy to operate, traditional sliding block by 1 end of slot place with the sliding slot on the second positioning plate 3 with
Afterwards, it is only necessary to which the middle part that slot 1 is passed through using positioning pin 9 is inserted into location hole 5, and is rotated by 90 ° and can complete to operate.
The present apparatus is safe and effective, by the way that adjustable fixed point is arranged at the middle part of slot 1, makes the relaxation degree of slot 1
Change, so that the width of crack between a door and its frame be made also to change, in this way, can effectively prevent pliers be inserted into crack between a door and its frame it
It is interior.
Present apparatus modulability is strong, and the position that slot 1 on the one hand can be inserted by replacement positioning pin 9 is adjusted, another
It is convenient to be adjusted by positioning pin 9 and the cooperation of which location hole 5, substantially increase the optional degree of user.
The utility model is easy to operate, clever structure, low in cost, easily manufactured, safely and effectively, substantially increases antitheft
The safety and convenience of hinge, ensure that the safety of indoor occupant.
