Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to make it easy to understand, Fig. 1 to Fig. 8 is please referred to, a kind of radix saposhnikoviae reinforcing of safety door buckle function provided by the present application
Device, comprising: the first support base 1, the second support base 2, elastic lock mechanism, trip line 6 and support component 3；Snap lock deduction
Structure is mounted on the first support base 1；The dropout part of elastic lock mechanism and the first support base 1 are rotatablely connected；Elastic lock mechanism
Locking member connect with trip line 6；Trip line 6 is connect with turning the handle；Support component 3 is fixed on the second support base 2.
It should be noted that as shown in Figure 1, door knob hand-motion trip line 6 makes to lock when people turns the handle indoors
Part movement, after dropout part loses the lock of locking member, rotates, windproof rod 11 loses lock down under the gravity of windproof rod 11
It being fallen after the support of tight part, the other end of windproof rod 11 starts due to the variation by force direction toward the movement of tripping direction,
Until skidding off support component 3, then windproof rod 11 is fallen on the ground.
As an improvement, as shown in Figure 2 to Figure 3, the first support base 1 and the second support base 2 are concave support base；Concave branch
It supports seat and is equipped with extension bar pedestal 9, outer panel 1-1 and interior plate 1-2；The bottom outer panel 1-1 is equipped with notch；First support base 1 and

It connects；Power part 5-3 is connect with trip line 6；Turning point 5-2 is provided with connecting shaft 12；Connecting shaft 12 and the fixed company of Z-type grip tab 5
It connects；Connecting shaft 12 and the first support base 1 are rotatablely connected, and 13 sets of torsional spring in connecting shaft 12.
It should be noted that door knob hand-motion trip line 6, Z-type threads off piece 5 de- when indoor people turns the handle
Turn under the drive of fastening wire 6 toward direction of action, latch portion 5-1 releases the lock to L-type tripping piece 4, and L-type threads off piece 4 in windproof rod
Around the bearing rotary of hinge under 11 gravity, windproof rod 11 is fallen on extension bar pedestal 9.When lock, Z-type grip tab 5 exists
Under the elastic force effect of torsional spring 13, latch portion 5-1 tightly clasps L-type tripping piece 4, at this point, L-type tripping piece 4 is used to support windproof rod
11。
It should be noted that 1 bottom plate 1-3 of the first support base is equipped with hanging hole 1-4, connecting shaft 12 injects hanging hole 1-4 and first
Support base 1 is rotatablely connected, and torsional spring 13 is wound in connecting shaft 12, and Z-type grip tab 5 is equipped with notch, torsional spring 13 in 13 junction of torsional spring
One end connect with Z-type grip tab 5, the other end is connect by notch with bottom plate 1-3, and Z-type grip tab 5 can be enhanced in torsional spring 13
Reset capability, when lock, latch portion 5-1 can tightly push down L-type tripping piece 4.
It should be noted that outer panel 1-1 and interior plate 1-2 are equipped with hole, axis as shown in fig. 6, hinge can also be replaced with axis
It is rotatablely connected in inserting hole with the first support base 1, axis is fixedly connected with L-type tripping piece 4；As shown in fig. 7, axis can also be with L-type
4 turning point integration of piece of threading off connects, and is equivalent to L-type tripping 4 turning point of piece and rises equipped with crown of roll, L-type tripping piece 4 and the first support
Seat 1 is rotatablely connected.
It should be noted that as shown in figure 8, Z-type grip tab turning point 5-2 can also it is integrated with connecting shaft 12 connection,
It is equivalent at the 5-2 deflection angle of turning point and is risen equipped with crown of roll, Z-type grip tab 5 and the first support base 1 are rotatablely connected, and torsional spring 13 is wound on
On crown of roll rises, one end of torsional spring 13 is connect with Z-type grip tab 5, and the other end is connect with bottom plate 1-3.
It should be noted that as shown in figure 5, power part 5-3 is equipped with the connecting hole 5-4 of connection trip line 6.
It should be noted that as shown in Figure 1, further including clip 7, clip 7 is mounted on door handle, and trip line 6 passes through card
Hoop 7 is connect with door handle, is fastened on one end of trip line 6 on door handle by clip 7.
It should be noted that as shown in Figure 1, further include line code 8, line code 8 is fixed on door, on wall or the first support base
On bottom plate 1-3, trip line 6 is brake cable, and when the door handle is turned, the interior core of brake cable is driven, and will be stopped by line code 8
Fare is fixed on the wall, guarantees the route of brake cable transmission.
It should be noted that further including windproof rod 11, windproof rod 11 makes using Q235 galvanized steel bar pipe.
It should be noted that being provided with cushion 10 on extension bar pedestal 9, prevent windproof rod 11 from falling on extension bar pedestal 9
It directly pops up, avoids the generation of safety accident.
It should be noted that the first support base 1 and the second support base 2 wash off molding using stainless-steel sheet.
It should be noted that a kind of windproof bracing means of safety door buckle function provided by the present application, comprising: first
Support seat 1, the second support base 2, elastic lock mechanism, trip line 6 and support component 3；Elastic lock mechanism is mounted on the first support
On seat 1；The dropout part of elastic lock mechanism and the first support base 1 are rotatablely connected；The locking member and trip line 6 of elastic lock mechanism
Connection；Trip line 6 is connect with turning the handle；Support component 3 is fixed on the second support base 2.When people rotates door knob indoors
When hand, door knob hand-motion trip line 6 acts locking member, after dropout part loses the lock of locking member, in the gravity of windproof rod 11
It is rotated down under effect, windproof rod 11 is fallen after losing the support of locking member, and the other end of windproof rod 11 is due to by active force
The variation in direction starts toward the movement of tripping direction, until skidding off support component 3, then windproof rod 11 is fallen on the ground.It solves
Due to the problem of safety door adds cross bar in opening direction, and people is unable to opening safety door indoors.
