Abstract
The utility model discloses a wind pressure resisting hand wheel lock. The wind pressure resisting hand wheel lock comprises a support, a cover plate, a driving wheel, a lock shaft and a lock bar and is characterized in that a cover plate is welded on the support, a shaft sleeve is welded at the centre of the cover plate, the lock shaft is welded at the center of the driving wheel, passes through the two ends of the shaft sleeve and is in screw joint with a hand wheel, a sliding chute is formed in the driving wheel, and one end of the lock bar is movably connected to the sliding chute which is an evolvent sliding chute. The wind pressure resisting hand wheel lock is mainly used for air blower houses in subways, tunnels and civil air-defense construction and under the shaft.
Description
Technical field
The utility model relates to a kind of handwheel lock, relates 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 lock jail, easily cause door distortion, leak out and be not durable.
Summary of the invention
The purpose of this utility model is to provide a kind of handwheel lock of Wind-Pressure Resistance, to solve the above-mentioned problem existing.
For achieving the above object, technical solution of the present utility model 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, on drive 4, be also provided with chute 8, one end of locking bar 9 is flexibly connected with chute 8.
Described chute 8 is involute chutes.
The beneficial effects of the utility model are: because Wind-Pressure Resistance handwheel lock of the present utility model has adopted, the special construction that a plurality of involute chutes add locking bar is set on drive, slided in one end of locking bar in chute, the other end inserts door behind free and relaxed in the lockhole of doorframe different directions and by handwheel open and close door lock and lock jail can Wind-Pressure Resistance, shock wave resistance, do not leak out, indeformable, durable in use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model drive.
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 utility model and the specific embodiment thereof are described in further detail.
Referring to Fig. 1-2, the utility model comprises 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, is also provided with chute 8 on drive 4, and one end of locking bar 9 is flexibly connected with chute 8.
Described chute 8 is involute chutes.
Key of the present utility model is on drive 4, to be provided with 3 involute chutes 8, one end of locking bar 9 is flexibly connected with chute and slides in chute, movable the pegging graft of lockhole on the other end and doorframe, involute chute is equivalent to cam wheel, when one 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 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 depart 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 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.
