124a clamping, when connecting rod 121b is moved right, the first idler wheel 122 can be withheld on positioning seat 120.
Positioning seat 120 includes that internal be equipped with passes through the seat ontology 120a in region for strut 121a, is used for seat ontology 120a
The positioning bolt part 120b being located on sliding rail 10, wherein seat ontology 120a can be slidably arranged on sliding rail 10, and seat sheet
Body 120a is slope 120c close to the end of locking part, and when strut 121a is moved with respect to seat ontology 120a, the first idler wheel 122 exists
It is rolled on the 120c of slope.
Present ontology 120a is equipped with positioning region 120d far from the end of slope 120c, and spring support 124b includes sliding setting
First connecting portion b1 on sliding rail 10, along the horizontal-extending second connecting portion b2 of 10 length direction of sliding rail, from the second connection
The third interconnecting piece b3 that portion b2 extends to region between two strut 121a, glass column 124a two-end part is in first connecting portion b1
Between the 120d of positioning region；Elastic parts 124c is between third interconnecting piece b3 and connecting rod 121b.
Specifically, glass column 124a is located at the top of elastic parts 124c and is exposed to outer, elasticity from the opening of sliding rail 10
Component 124c is spring g, spring g and glass column 124a of the both ends conflict between third interconnecting piece b3 and connecting rod 121b
It is arranged in parallel.
In this example, spring g has two, and is symmetrical arranged about glass column 124a.
Second connecting portion b2 separates glass column 124a and spring g, and spring g is hidden, while in second connecting portion b2
Bottom be additionally provided with the separator 125 for being spaced two spring g.
In addition, locking part 123 is second be rotatably arranged between two strut left parts around sliding rail width direction
Idler wheel, auxiliary section 11a include with the ontology a1 with the second idler wheel matching slot and being located at setting in ontology a1 close to positioning seat
120 wedging module a2, wherein wedging module a2 is in the gradually smaller wedging slope of thickness from ontology a1 to positioning seat 120.Cause
This is locked by wedging the setting on slope convenient for auxiliary section 11a and the cooperation of locking part 123.
In conclusion the state description of the present embodiment is as follows:
When door and window, which is in closure, is not switched on state, in conjunction with attached drawing 2, under the support of glass column 124a, so that the first rolling
Wheel 122 is withheld on present ontology 120a, and bracket 121 is static with respect to ontology 120a, meanwhile, spring g is in compressive state；
When windowing, rocker arm 3 struts window outward, and auxiliary section 11a is mobile to locking part 123, and wedges and pass through matching slot
When the two matches, under the action of spring g, the movement of limit bracket 121, at this point, the locking of window in the open state
State；
When a fire, glass column 124a is broken, and spring support 124b loses the active force of glass column 124a, and in bullet
Under the action of spring g, bracket 121 rolls to the left on the slope with the first idler wheel 122, at this time the second idler wheel (namely locking part
123) it is separated with auxiliary section 11a, then, under the effect of cylinder body 2, sliding block is mobile, the inside folding of rocker arm 3, and then window is closed.
