Abstract
The utility model discloses self-locking bolt for locking and unlocking a door or a window. With the self-locking bolt being used, the cases that the door or window can be damaged and a bolt rod can be bent due to the crash between the door or window and a frame can be prevented. By the wind power, the gravity of the bolt rod, or the elasticity of a spring, the door or the window can be self-locked. Compared with an original bolt, the characteristics of the self-locking bolt is that the self-locking bolt head has a curvilinear surface or an oblique section, and a spring is installed on an upper guiding frame; the self-locking bolt can be used for locking and unlocking the door or window.
Description
The utility model relates to the latch of closing the doors and windows.
The utility model is by the latch development of selling on the market.
Known latch is by base plate, upper valve crosshead guide, guide card, drawing strickle guide, bolt rod, pull bar, plug housing constitute down, do not have an auto-lock function, and bolt rod with or window frame flexible modification when bumping.
The purpose of this utility model is: when preventing to draw together wind, because the collision of door, window and frame causes door, window to damage and the bolt rod bending, make the door and window self-locking by wind-force bolt rod gravity or spring force.
Technical solution of the present utility model is: whole latch is by the upper valve crosshead guide (3) of base plate (2) guide bar moving linearly, guide card (4) the guide bar that the restriction bolt rod rotates and the following drawing strickle guide (7) of fork moving linearly, be subjected to the drawing strickle guide restriction also partly or entirely to place the bolt rod (5) of drawing strickle guide, the pull bar (6) that upper and lower push-and-pull bolt rod is used, with bolt rod be an integral body, be positioned at the bolt rod lower end, and have the fork (8) of curvilinear plane or sloping section, place spring (1), plug housing (9) in the upper valve crosshead guide.
When causing the collision of window page or leaf and window frame when blowing, Bolt with latching action head curvilinear plane or sloping section contact with plug housing, and by plug housing jack-up, therefore can not produce flexural deformation, when fork moves to the socket hole position, be subjected to the promotion of spring, headed into socket hole, thereby reach self-locking, when latch is installed on the position of fork directed towards ground, can not establish spring, can not self-locking and cause door by gravity self-locking (only needing curvilinear plane of processing or sloping section on the fork of former latch this moment) thereby solved former latch, the problem of window damage and bolt rod bending.
Accompanying drawing is the shaft side figure of an embodiment of the utility model
The material of latch each several part is made with metal material or plastics, and bolt rod is four prisms cylinder or cylinder, and the length of base plate equals upper valve crosshead guide, guide card, lower drawing strickle guide sum. The length of lower drawing strickle guide equals the length of fork, and the length of guide card equals fork length and adds the pull bar diameter, and it is long that upper valve crosshead guide, length equal 2.5 times of forks.
Claims (2)
1, a kind of for the latch of closing door, window, have base plate, upper valve crosshead guide, guide card, drawing strickle guide down, bolt rod, pull bar, plug housing is characterized by: fork has curvilinear plane or sloping section.
2, latch according to claim 1 is characterized in that: spring is housed in the upper valve crosshead guide.
