Abstract
The invention discloses an air-pressure resistant hand wheel lock. The air-pressure resistant hand wheel lock comprises a support, a cover plate, a transmission wheel, a lock shaft and a lock rod, and is characterized in that the cover plate is welded on the support, a shaft bushing is welded at the center of the cover plate, the lock shaft is welded at the center of the transmission wheel, the lock shaft penetrates the shaft bushing, two ends of the lock shaft are in threaded connection with the hand wheel, the transmission wheel is provided with a slide groove, and one end of the lock rod is movably connected with the slide groove which is a an involute slide groove. The air-pressure resistant hand wheel lock is mainly used for blower rooms in subways, tunnels, wells, air-defense construction and the like.
Description
Technical field
The present invention relates to a kind of handwheel lock, relate in particular to a kind of handwheel lock of Wind-Pressure Resistance.
Background technology
The air blast machine room that subway, tunnel, down-hole, civil air defense constructions and installations etc. are located, traditional door lock is difficult to use, reason is that the blast at this place is large, door lock is difficult to the lock jail, easily cause door distortion, leak out and be not durable.
Summary of the invention
The object of the present invention is to provide a kind of handwheel lock of Wind-Pressure Resistance, to solve the above-mentioned problem existed.
For achieving the above object, technical solution of the present invention is: a kind of handwheel lock of Wind-Pressure Resistance, comprise support, cover plate, drive, lock shaft and locking bar, it is characterized in that: on described support 1, be welded with cover plate 2, the center of this cover plate is welded with axle sleeve 3, and the center of drive 4 is welded with lock shaft 5, and this lock shaft is spirally connected through axle sleeve 3 its two ends and handwheel 7, also be provided with chute 8 on drive 4, an end of locking bar 9 and chute 8 are flexibly connected.
Described chute 8 is involute chutes.
The invention has the beneficial effects as follows: because Wind-Pressure Resistance handwheel lock of the present invention has adopted, the special construction that a plurality of involute chutes add locking bar is set on the drive, one end of locking bar is slided in chute, the other end insert in the lockhole of doorframe different directions and by handwheel open and close door lock the door behind free and relaxed and lock jail can Wind-Pressure Resistance, shock wave resistance, do not leak out, indeformable, durable in use.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of drive of the present invention.
In figure: 1-support, 2-cover plate, 3-axle sleeve, 4-drive, 5-lock shaft, 6-screw, 7-handwheel, 8-chute, 9-locking bar, 10-Compress Spring, 11-stainless steel ball, 12-nut, 13-spring washer, 14-spring housing, 15-plain cushion.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention and the specific embodiment thereof are described in further detail.
Referring to Fig. 1-2, the present invention includes support, cover plate, drive, lock shaft and locking bar, it is characterized in that: on described support 1, be welded with cover plate 2, the center of this cover plate is welded with axle sleeve 3, the center of drive 4 is welded with lock shaft 5, this lock shaft is spirally connected through axle sleeve 3 its two ends and handwheel 7, also is provided with chute 8 on drive 4, and an end of locking bar 9 and chute 8 are flexibly connected.
Described chute 8 is involute chutes.
Key of the present invention is to be provided with 3 involute chutes 8 on drive 4, one end of locking bar 9 and chute are flexibly connected and slide in chute, lockhole on the other end and doorframe is movable pegs graft, the involute chute is equivalent to cam wheel, when an end of locking bar moves along a curved path in chute, the other end of locking bar is just reciprocating, when handwheel 7 is done the left or right rotation, one end of locking bar just moves along a curved path in chute, and the other end of locking bar is just made reciprocal rectilinear motion, insert or break away from the lockhole on doorframe, thereby realizing the function of locking a door and opening the door.Due to locking bar from three different directions by the door lock jail, therefore can Wind-Pressure Resistance, do not leak out, good seal, indeformable and durable in use.Screw 6 plays fixedly lock shaft.
Claims (2)
