Abstract
The invention discloses a kind of used in fire-fighting go-cart lockable mechanism, this lockable mechanism comprises the latch hook fixed head be installed on floor, and latch hook is fixed on described latch hook fixed head, and described latch hook manipulatable end is connected with pull bar, and spring housing is contained in the link of pull bar.Adopt the go-cart lockable mechanism of technical solution of the present invention, the beneficial effect of generation is that structure is simple, easy to operate, and effectively reliable.A preferred technical scheme of the present invention is that the manipulatable end of latch hook is connected with pull bar by contiguous block, and such structure is conducive to spring and better embodies gyroscopic action, avoids contacting with the latch hook of long-term action, better protects spring.Be that described contiguous block and pull bar are rigidly connected by nut as another preferred technical scheme of the present invention, avoid spring and be subject to the infringement of cross force, thus effectively extend spring life.
Description
Technical field
The present invention relates to the locking system of go-cart, especially relate to a kind of lockable mechanism for fire fighting truck go-cart.
Background technology
Go-cart locking mode in the market for fire fighting truck has two kinds: one to be use rope bondage to fix; Another kind uses baffle plate and pin fixing vehicle wheel.
The first locking mode is not firm, and rope is meeting wear and aging in long-term use procedure, and uses very inconvenient, unsightly; The second locking mode utilizes baffle plate and pin, repeats cumbersome, uses inconvenience, and degree of blocking does not reach the requirement of fire protection sector.
Summary of the invention
It is more effective reliable that the technical problem to be solved in the present invention is to provide one, and used in fire-fighting go-cart lockable mechanism simple to operate.
For solving the problems of the technologies described above, lockable mechanism of the present invention comprises the latch hook fixed head be installed on floor, and latch hook is fixed on described latch hook fixed head, and described latch hook manipulatable end is connected with pull bar, and spring housing is contained in the link of pull bar.
Adopt the go-cart locking system of said structure, structure is simple, easy to operate, and effectively reliable.Be provided with fixed head, and latch hook is rigidly connected is fixed on fixed head, and fixed head is installed on floor, because this increasing the firm performance of whole latch hook; The manipulatable end of latch hook is connected with pull bar, is controlled the operative orientation of latch hook, in addition, be set with spring at the link of pull bar, utilize the Hui Li of spring that latch hook is turned round when locking, the spacing latch hook of blocking arm of fixed head, thus play locking effect by pull bar.
As a further improvement on the present invention, the manipulatable end of described latch hook is connected with pull bar by contiguous block.Be connected with pull bar by latch hook by contiguous block, such structure is conducive to spring and better embodies gyroscopic action, avoids contacting with the latch hook of long-term action, better protects spring.
As a further improvement on the present invention, latch hook is fixed on described latch hook fixed head by bearing pin, adopts bearing pin latch hook to be fixed on latch hook fixed head and the fixed performance of latch hook is promoted further, and in addition, such structure is also convenient to staff's maintenance.
As a further improvement on the present invention, pull bar is limited in pull bar gripper shoe, easy to operate, be convenient to control.
As a further improvement on the present invention, contiguous block and latch hook are by pinned connection, and the fixed performance of such contiguous block and latch hook promotes further, and maintenance also facilitates.
As a further improvement on the present invention; described contiguous block and pull bar are rigidly connected by nut; pull bar and contiguous block adopt and are rigidly connected, and be conducive to realizing the integrated action of contiguous block and pull bar, this is also more conducive to protecting spring not suffer the destruction of cross force simultaneously.
As a further improvement on the present invention, the manipulatable end of pull bar is provided with handle ball, the setting of this handle ball, and its beneficial effect produced is that the hand of protection workman preserves from when operating pull bar, makes it more easily operate pull bar.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiments of the present invention are described further:
Fig. 1 is structural representation of the present invention;
Wherein: 1, handle ball; 2, pull bar gripper shoe; 3, pull bar; 4, latch hook fixed head; 5, latch hook; 6, bearing pin; 7, spring; 8, nut; 9, contiguous block; 10, bearing pin.
Detailed description of the invention
As shown in Figure 1, this lockable mechanism comprises the latch hook fixed head 4 be installed on floor, latch hook 5 is fixed on described latch hook fixed head 4, latch hook 5 manipulatable end is connected by contiguous block 9 with pull bar 3, and spring 7 is sleeved on the link of pull bar 3, and latch hook 5 is fixed on latch hook fixed head 4 by bearing pin 6, pull bar 3 is limited in pull bar gripper shoe 2, contiguous block 9 is connected by bearing pin 10 with latch hook 5, and contiguous block 9 and pull bar 3 are rigidly connected by nut 8, and the manipulatable end of pull bar 3 is provided with handle ball 1.
Operating personnel pass through pull bar 3 outward, and pulling force makes latch hook 5 rotate by the transmission of contiguous block 9 grade, and spring 7 also compresses in the vertical, thus makes go-cart lose constraint, and go-cart just can pull out; During locking go-cart, go-cart pushed and make it be tied a little to spacing place, unclamp the pull bar 3 of pulling, the elastic force of spring 7 can make latch hook 5 go back to, and the blocking arm of latch hook fixed head 4 or latch hook own dimensions can spacing latch hooks 5, thus locking go-cart.
Adopt the go-cart lockable mechanism of structure of the present invention, its beneficial effect produced is that structure is simple, easy to operate, and effectively reliable.
