Abstract
The utility model discloses a bolt. In particular, a close type semiautomatic bolt for door and window which can be conveniently locked and unlocked automatically by press is disclosed. The utility model belongs to the technical field of the hardware for daily use. A bolt body is form by a straight bolt shaft 2 which penetrates through a main shell 5 lengthways. The bolt shaft 2 is provided with an opening bolt 3 which fixes the bolt shaft, an opened locking plate 8, and a spring 7. The bolt shaft 2 is provided with a locking slot 4. The opened locking plate 8 is locked tightly by the elastic force of the spring 7, the bolt shaft is made to generate the driving force for opening automatically, and the utility model task is completed. The disadvantages that the traditional bolt switch is not flexible and firm and is inconvenient to be installed are overcome. The utility model can be used in the doors and windows of various buildings.
Description
The utility model discloses the closed semi-automatic thumb-latch that to press locking easily, press automatic unlatching.It is a kind of miscellaneous hardware.
Traditional thumb-latch is made up of the main casing and the subshell of the band symmetry fixed tab of L type bearing pin and full open model.Though this thumb-latch structure is simple, result of use is bad.Main shortcoming is the switch inconvenience, two 90 ° of L type bearing pin elder generation retrotorsions just can need be finished action expendable locked or that open.The upright spacer of main casing usually can scratch finger or scratch clothes in the use; Mechanical strength and polarization are poor, and the vibrations that automatically closing door and window produced that stronger wind-force causes usually can make bearing pin stretch out voluntarily, thereby make latch bearing pin deformed damaged when door and window is closed once more automatically; Inconvenience is installed, and subshell often needs to imbed in the doorframe and window frame fixing, makes the installation work trouble.Many defectives of above traditional latch are for the utility model proposes good invention problem.
Goal of the invention of the present utility model be design a kind of easy to use, open closed semi-automatic thumb-latch flexible, firm, easy for installation.
Figure of description 1 is an organigram of the present utility model.Among the figure: 1 Capsule, 2 bearing pins, 3 cottor pins, 4 lock slots, 5 main casings, 6 square holes, 7 springs, 8 open locking plate, 9 fixing holes, 10 fixed tabs, 11 pin-and-holes, 12 subshells, 13 fixing holes, 14 fixed tabs, 15 release the button.
Figure of description 2 is organigrams of the utility model lock-out state.
Figure of description 3 is organigrams of the utility model opening.
The technical solution of the utility model shows as: adopted a direct selling axle that vertically runs through main casing 5 2 consist of the latch main body, split pin 3, unlatching locking plate 8, the spring 7 of fixed pin shaft 2 have been installed on bearing pin 2 successively, near split pin 3, opened lock slots 4 by opening locking plate 8 bearing pin on one side, utilize the elastic force locking of spring 7 to open locking plate 8 and make bearing pin 2 produce the motive force of automatically opening, finished the pin task fixed and that automatically open of latch.
Followingly structure of the present utility model is described: a kind of closed semi-automatic thumb-latch according to Figure of description, comprise the known fixed tab 10,14 that is positioned at the band fixing hole 9,13 of main casing 5 and the symmetrical distribution of subshell 12 two sides, it is characterized in that main casing 5 is the hollow rectangular shapes that are closed state, vertically connect the bearing pin 2 that main casing 5 has been installed cylindrical shape, to the other end cottor pin 3 of fixed pin shaft 2, two faces that do not face mutually being installed successively from an end on the bearing pin 2 in main casing 5 has circle hole sleeve on bearing pin 2
Type is opened locking plate 8; Be positioned on the bearing pin 2 of opening locking plate 8 centres spring 7 is installed, one end of spring 7 and bearing pin 2 are fixing, the other end is crimped on an inboard of opening in 8 two faces that do not face mutually of locking plate, angle α between this face and the face that faces mutually releases the button 15 opening the square hole 6 that has on the locking plate 8 on a square convex and the main casing 5 formation that coincide in obtuse angle; Opening annular lock groove 4 by opening on locking plate 8 bearing pin 2 on one side near the cottor pin 3, the width of annular lock groove 4 and the degree of depth are wherein being advisable opening locking plate 8 flexible embeddings; Subshell 12 is the hollow square shapes that are closed state, has a pin-and-hole 11 at least on the face in the middle of the fixed tab 14.In order to adapt to the needs of different mode of occupation, subshell 12 can have pin-and-hole 11, both sides to have the rectangle metal sheet of fixing hole 13 to substitute by the centre, and this structure is particluarly suitable for installing and using on the window.For easy to use, Capsule 1 is installed at an end of bearing pin 2.
The utility model is separately fixed at the major-minor shell on door and window and the doorframe and window frame with screw in use, pressing Capsule 1 makes the other end of bearing pin 2 combine with pin-and-hole 11, open locking plate 8 and embed and make bearing pin 2 lockings in the lock slots 4, open locking plate 8 owing to spring 7 is pressed together itself and lock slots 4 to the elastic acting force of its angle α face in obtuse angle; When needs are opened, to open releasing the button on the locking plate 8 and 15 overcome the radial effect power that spring is split the sheet that undoes the lock as long as press gently, bearing pin 2 takeoffs under the effect of spring, and then latch is opened.
Major advantage of the present utility model is totally-enclosed when being to use state, and sturdy and durable not hanging clothes and human body opened easy to usely flexibly, and simple installation is of many uses, and the door and window that can adapt to various structures is installed and used.
