Description
Technical field
The utility model relates to protective door technical field more particularly to a kind of locking and use the closed guard gate of the locking.
Background technique
People's air defense door latching system is the most important structure that closed guard gate resists explosion wave overbottom pressure, is to guarantee that closed guard gate exists
Closed guard gate's sealing function most important component is also able to maintain when by remainder pressure of shock wave.Existing Authorization Notice No. is
The utility model patent of CN204703637U provides blocking device built in a kind of closed guard gate's door leaf, including sequentially connected shakes
Handle, commutator, retarder, scissors reduction top, lock head structure, the lock head structure include locking head, locking set, split pin.?
In actual use, rocking handle rotates and drives waling stripe by commutator, then vertically to connect up and down using scissors reduction top
Bar simultaneous retractable drives locking head to lock locking set or lock out to be latched and covers, and completes locking and opening after closing the door or opening the door and appoints
Business.
But in actual use, if locking head misalignment locking set, vertical links drive locking head rise will so that
Locking head collides with locking set or doorframe, it is possible to can damage locking head, or locking head and vertical links are occurred
Deformation；If things go on like this, locking head matches the attainable latch effect of institute with locking head and will be greatly reduced, so that be entirely latched
Reduced service life, and then the protective performance of entire closed guard gate is influenced indirectly.
Utility model content
For the shorter problem of existing locking service life, first technical purpose of the utility model is to provide one kind and closes
Lock extends the service life of locking using bolt, locking bar and elastic parts for connecting bolt and locking bar, guarantees closed guard gate
Protective performance.
To realize above-mentioned first technical purpose, the utility model provides following technical solution:
A kind of locking, including connecting rod and the hinged tapered end for being set to connecting rod one end, the tapered end includes being used for articulated linkage
Locking bar and be set to bolt of the locking bar far from connecting rod one end；The bolt is close to locking bar one end integrally formed with inserted link, institute
Inserted link is stated with locking bar adjacent end portion in mating；The locking further includes the elastic parts for connecting bolt and locking bar, described
Elastic parts includes the elastic component being sheathed on inserted link and the connection component for locking latch and locking bar, the elastic component
Both ends push against bolt and locking bar respectively.
By using above-mentioned technical proposal, tapered end is splitted into locking bar and bolt two parts, and by taking shape on bolt
Inserted link formed with locking bar it is mating so that inserted link can stretch in locking bar；Meanwhile bolt and locking bar being connected using elastic parts
It picks up, the both ends of elastic component push against bolt and locking bar, and mating connection component guarantees the stability and company that bolt is connect with locking bar
Globality after connecing.In actual use, when bolt and other positions of closed guard gate collide, elastic component can be to collision
Buffering is played the role of in impact, reduces the risk of the parts damages such as tapered end damage and connecting rod, facilitates the use for extending the locking
Service life guarantees that closed guard gate can keep good protective performance for a long time indirectly.
The utility model is further arranged to: integrally formed with the first otic placode on the bolt, the locking bar is far from connecting rod
End integrally formed with the second otic placode；The elastic component is compressed spring, and the compressed spring is sheathed on inserted link, and described
