The bolt is the bolt buckle which is capable of opening automatically, comprising a ring edge, a buckle seat and a bolt rod, wherein, the buckle seat is provided with an arched back whose interior is the position where the bolt rod is used for making the longitudinal movement. The utility model used in the door and the window is characterized in that the interior of the buckle seat is provided with a shape memory alloy spring; the shape memory alloy spring can restore the original position so as to drive the bolt rod to move after the shape memory alloy spring is heated and deforms.

Description

Automatic-opening bolt button

The utility model relates to the latch of using on the door and window, especially refers to a kind of automatic-opening latch.

Existing latch as shown in Figure 1, so-called bolt button generally claims latch, it is separately fixed at doorframe and door sheet by ring seat 91 and Button Block 92, utilizes moving of tightening latch 93, reaches the purpose of switching, is used on the building window, can manual unlocking when needing; The only curtain wall face of glass that is installed in that has owing to lack openable design, meets emergency, and as fire, need are knocked at the door by the fire fighter and gone into, and are convenient inadequately.

The purpose of this utility model provides a kind of automatic-opening bolt button, promptly automatic-opening latch.

The purpose of this utility model is achieved in that automatic-opening bolt button, it comprises ring seat, Button Block and tightening latch, Button Block has hogback, for tightening latch moves the place as lengthwise, it is characterized in that in the back of the body: be provided with the shape memory alloy spring that is heated and resets and move after the distortion in the Button Block with the drive tightening latch.

Above-mentioned design mainly is to utilize the characteristic of marmem to be made as spring, and when meeting fire, door and window is heated and opens automatically, so that personnel's turnover.In addition, the ring lip of protrusion is established at a back side of Button Block, and the tightening latch end can be established the cap head of protrusion, and full spring is closed in shape note memory can be set in cap head and the tightening latch that encircles between lip; Also can in Button Block away from the ring seat end be set as sealing for the fixing wall of shape memory alloy spring one end, shape alloy spring end in addition is fixed in tightening latch; Perhaps, tightening latch is provided with the screw for a screw rod combination, and the back of the body of Button Block is provided with screw rod and can protrudes in its outside and gripped mobile open-work groove.
