Abstract
The utility model relates to the field of door/window members, and particularly relates to a bolt. The bolt comprises a bolt base, a plug and a bridge-shaped baffle plate, wherein the middle part of the bridge-shaped baffle plate forms a circular arch shape; flat plates which horizontally extend outwards are arranged at two circular-arch-shaped ends; one end, far away from the circular-arch-shaped part, of one flat plate is connected with the plug; a fixing device for connecting the bridge-shaped baffle plate is arranged on the bolt base; the bridge-shaped baffle plate can generate relative displacement together with the bolt base; a strip hole is formed in the part, opposite to the middle part of the bridge-shaped baffle plate, of the bolt base; a rotatable spanner is arranged on the strip hole; a connecting shaft for controlling the bridge-shaped baffle plate to move is arranged between the spanner and the bridge-shaped baffle plate. By adopting the bolt provided by the utility model, the bridge-shaped baffle plate is arranged on one side, contacting a door, of the bolt base, and the bridge-shaped baffle plate plays a protecting role on the spanner, so that the damage to spare parts caused by friction is effectively prevented, and the service life of the bolt is ensured.
Description
Technical field
The utility model relates to component of the doors and windows field, in particular to a kind of latch.
Background technology
At present, the latch that security door is used, its fork all connects together with plug housing, by pulling spanner, drives plug to move, and realizes the folding of latch; Wherein, the plug housing back side is directly to embed in door, and the inner body of latch directly contacts with the inside of door, during use, inner body easily produces friction with the inside of door, and use easily causes the damage of latch back side component for a long time, loss is too fast, often changes, and increases cost.
Utility model content
The purpose of this utility model is to provide a kind of latch, to solve the above problems.
A kind of latch is provided in embodiment of the present utility model, has comprised plug housing, plug and bridge type baffle plate;
Described bridge type baffle plate middle part is dome-shaped, and dome-shaped two ends are outside horizontally extending flat board, and a described flat board is connected with described plug away from dome-shaped one end partly;
Described plug housing is provided with for connecting the fastening devices of bridge type baffle plate, and described bridge type baffle plate can produce relative displacement with described plug housing;
The opposite position at the middle part of described plug housing and described bridge type baffle plate is provided with bar hole, and described bar hole is provided with rotating spanner, between described spanner and described bridge type baffle plate, is provided with the connecting axle moving for controlling described bridge type baffle plate.
A kind of latch of the utility model above-described embodiment, plug housing arranges bridge type baffle plate with the side that contacts of door, and bridge type baffle plate has protective effect to spanner, has effectively prevented because the damage of the part that friction causes, and has guaranteed the application life of latch.
Accompanying drawing explanation
Fig. 1 shows one of structural representation of a kind of latch described in the utility model embodiment;
Fig. 2 show a kind of latch described in the utility model embodiment structural representation two;
Fig. 3 shows the upward view of a kind of latch described in the utility model embodiment.
In figure:
1, plug housing; 2, header body; 3, Connection Block; 4, bridge type baffle plate; 5, flat board; 6, rotating shaft; 7, connecting axle; 8, torsion spring; 9, spanner.
The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
As Figure 1-3, a kind of latch, comprises plug housing 1, plug and bridge type baffle plate 4;
Bridge type baffle plate 4 middle parts are dome-shaped, and dome-shaped two ends are outside horizontally extending dull and stereotyped 5, and one flat plate 5 is connected with plug away from one end of dome-shaped part;
A kind of latch of above-described embodiment, plug housing 1 arranges bridge type baffle plate 4 with the side contacting of door, and 4 pairs of spanners 9 of bridge type baffle plate have protective effect, have effectively prevented because the damage of the part that friction causes, and have guaranteed the application life of latch.
In order further to make this insert, can mutually combine with the door of various models, plug comprises Connection Block 3, and Connection Block 3 is connected with dismountable header body 2.Preferably, Connection Block 3 is provided with screwed hole, and header body 2 is provided with screw rod, header body 2 with Connection Block 3 for being threaded.Header body 2 is dismountable, for the door of different model, the header body 2 that different size can be installed, and if header body 2 damaged, only need to change header body 2.
Further, plug housing 1 is provided with two groups of fastening devicess, and every group of fastening devices comprises two risers that are oppositely arranged, and on two risers, cross-under has rotating shaft 6, between rotating shaft 6 and plug housing 1, is provided with gap, and two flat boards 5 are respectively through two gaps.
Further, connecting axle 7 takes the shape of the letter U, comprise one group of sidewall and a base plate, two sidewalls are connected with spanner 9 away from one end of base plate, between two sidewalls, be provided with transverse axis, on transverse axis, cross-under has torsion spring 8 and junction plate, and one end of junction plate is fixedly connected with dull and stereotyped 5, torsion spring 8 one end are connected on base plate, and the other end is connected on dull and stereotyped 5.
Spanner 9 is all connected by removable screw with sidewall with plug housing 1, spanner 9.When spanner 9 need to be changed, only need to change separately spanner 9 by dismounting screw, do not need whole latch all to change, cost-saving.
Transverse axis and base plate are parallel to each other.Transverse axis and base plate are parallel to each other, comparatively laborsaving while making to pull spanner 9, convenient use.
Bridge type baffle plate 4 and plug are for being welded to connect.Guarantee the interlock of plug and bridge type baffle plate 4.
This latch at original plug with on basis that plug housing one is combined, original welded type plug is changed over to spiral dismountable plug, by screw type propulsion method, can directly dismantle plug, be convenient for changing longer plug, can be used in like this above a greater variety of doors; And if any damage, replacing for convenience detach.
At the plug housing back side, fixed a monoblock bridge type baffle plate 4, protected the back side of latch, the rear end of spanner 9 can directly not contacted with door, effectively prevented because the damage of the part that friction causes; Directly the end structure of plug is welded in addition to one end of bridge type baffle plate 4; Guarantee the interlock of plug and bridge type baffle plate 4; Spanner 9 interfixes with connecting axle 7, and connecting axle 7 is fixed on bridge type baffle plate by transverse axis and torsion spring, thus when spanner is pulled up and down, by connecting axle, drive bridge type baffle plate to move together, thus promoted the flexible of plug.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
