Abstract
The invention discloses a pneumatic lock. The pneumatic lock comprises a cylinder (1), a drive connecting rod (2), an upper driven connecting rod (3), a lower driven connecting rod (4), an upper bolt (5), a lower bolt (6) and a door plate (9), and is characterized in that: the upper driven connecting rod (3) is fixedly connected with the upper bolt (5); the lower driven connecting rod (4) is fixedly connected with the lower bolt (6); the door plate (9) is provided with a fixed pivot; one end of the cylinder (1) is connected with the fixed pivot while the other end of the cylinder (1) is movably connected with the drive connecting rod (2); a shaft (7) is fixedly arranged on the door plate (9); the middle part of the drive connecting rod (2) is connected with the shaft (7) moveably; the two ends of the drive connecting rod (2) are respectively connected with the upper driven connecting rod (3) and the lower driven connecting rod (4) moveably; and the drive connecting rod (2) drives the upper driven connecting rod (3) and the lower driven connecting rod (4) to move under the action of the cylinder (1). The pneumatic lock has a simple structure and high safety.
Description
Technical field
The present invention relates to the used special use in a kind of field of guarding against theft lock, especially a kind of oil truck special-purpose anti-theft gaseous moving lock of chamber door of draining the oil.
Background technology
Environment is abominable during the oil truck transportation, is in the explosive gas atmosphere of high-risk, and requirement of explosion proof is higher, and the friction of general mechanical lock metal is easy to generate static, is easy to cause that accident takes place, and has satisfied not the needs of transporting safely.Conventional door lock adopts the minitype motor driving gear, and intermediary element such as chain drive the switch of dead bolt, complex structure; The mode that frame for movement employing equipment in the past exposes is fixed; Destroyed by stealer easily, the size of this external cause dead bolt and connecting rod is indefinite, and is more loaded down with trivial details during installation.
Summary of the invention
The object of the invention provides a kind of simple in structure, employing air cylinder driven, is easy to the gas-operated lock that oil truck is transported safely.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of gas-operated lock; Comprise cylinder, drive connecting rod, last follower link, following follower link, upper lock tongue, following dead bolt, door-plate, last follower link is fixedly connected with upper lock tongue; Following follower link is fixedly connected with following dead bolt; A fixed support is arranged on door-plate, and an end of cylinder is connected with fixed support, and the other end of cylinder and drive connecting rod flexibly connect; Be fixed with axle on the door-plate, the middle part of drive connecting rod flexibly connects with axle, and the two ends of drive connecting rod flexibly connect with last follower link, following follower link respectively, and drive connecting rod is driving follower lever, follower link motion down under the effect of cylinder; Thereby realize upper lock tongue, dead bolt, springing into and ejecting in lockhole down.
Said cylinder and vertical direction acutangulate.
Said cylinder can place drive connecting rod upside or downside.
Said cylinder is that type is stretched in single-acting in advance.
The said follower link that goes up adopts with following dead bolt and is threaded with upper lock tongue, following follower link.
Said upward follower link and upper lock tongue, following follower link adopt with following dead bolt and are welded to connect.
Said upper lock tongue, following dead bolt adopt copper material, and last follower lever, following follower lever also are copper material.
The invention has the beneficial effects as follows: simple in structure, employing cylinder directly drives the gas-operated lock of dead bolt, can realize Long-distance Control.Upward follower link, following follower link have flexible adjustable function, are applicable to various operating modes.All executing agencies are all hidden in the Yu Menti, are not easy to be destroyed by stealer, upper lock tongue, down dead bolt, go up follower lever, follower lever adopts copper material down, is not easy to produce static and spark, the safety anti-explosive performance is good.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Accompanying drawing 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of gas-operated lock comprises cylinder 1; Drive connecting rod 2, last follower link 3, following follower link 4, upper lock tongue 5, following dead bolt 6, ventilating pipe 8, door-plate 9, door-plate 9 is provided with the lockhole that cooperates with dead bolt, and last follower link 3 is fixedly connected with upper lock tongue 5; Following follower link 4 is fixedly connected with following dead bolt 6; A fixed support is arranged on door-plate 9, and an end of cylinder 1 is connected with fixed support, and the other end of cylinder 1 and drive connecting rod 2 flexibly connect; Be fixed with axis of rotation 7 on the door-plate 9; The middle part of drive connecting rod 2 and axis of rotation 7 flexibly connect; The two ends of drive connecting rod 2 are respectively with last follower link 3, follower link 4 flexibly connects down; Drive connecting rod 2 serves as to support knee-action with axis of rotation 7, follower lever 3, follower link 4 motions down in the drive, thus accomplish dead bolt springing into and ejecting in lockhole.All executing agencies all hide in door-plate 9, and last follower link 3, follower link 4 can adopt with the connected mode of dead bolt and be threaded down, also can adopt the fixed connection mode that waits other of welding.Cylinder 1 is stretched type in advance for single-acting, and cylinder can place drive connecting rod upside or downside, and cylinder 1 acutangulates with vertical direction.Last follower lever 3, upper lock tongue 5, down follower lever 4, dead bolt 6 adopts copper materials down.
At closing time, dead bolt utilizes the spring deformation of cylinder 1 itself, the compression of stressed back, and dead bolt springs into the lockhole place, and door lock is tight.
When opening the door, through the contraction of cylinder 1, follower link 3 in the drive, follower link 4 actions down, last follower link 3 is by drop-down, following follower link 4 by on draw, thereby upper lock tongue 5 all is in contraction state with following dead bolt 6, dead bolt ejection lockhole is opened.
