Specific embodiment
The utility model embodiment provides a kind of site construction protective fence, as shown in figs. 1-11, including two support rods 1
And multiple cross bars 1 for being used to connect two support rods 1.Support rod 1 includes multiple slots 11 being inserted into for cross bar 1,
Multiple fixture blocks 12 are provided in slot 11.The quantity of fixture block 12 is 4, and fixture block 12 overturns 90 ° when cross bar 1 enters slot 11
It is caught in cross bar 1.Card slot 22 compatible with fixture block 12 is offered on cross bar 1, and card slot is embedded in by one end of fixture block 12
In 22, reaches and cross bar 1 is fixed on support rod 1.
The inside of cross bar 1 offers a plurality of cavities 21, and air bag 4 is equipped in cavity 21.Air bag 4 is internally provided with gear
Plate 41 is equipped with compressed air bottle 42 in baffle 41, is full of compressed air in bottle.42 surrounding of compressed air bottle is equipped with pedestal
43, spring 1 is installed between baffle 41 and pedestal 43.When baffle 41 is collided, spring 1 is squeezed generation bullet
Power slows down impact force.Multiple grooves 45 are offered on baffle 41, when baffle 41 is by certain shock, baffle 41 opens up recessed
It is hit and is split at slot 45, hit and split place and sharp towards 410 points of the baffle of compressed air bottle 42, compressed air bottle 42 is punctured, it is internal
Compressed air release and be full of air bag 4, to reduce impact.
The site construction protective fence, by opening up groove 45 on baffle 41, so that baffle 41, which is hit, will compress sky when splitting
Gas cylinder 42 punctures, and compressed air passes through baffle 41 and pedestal 43 to improve the buffer capacity of protective fence full of air bag 4
It is inside connected with spring 1, improves the impact resistance of protective fence, protective fence is avoided to be led to compressed air bottle 42 by minor impact
Rupture, causes unnecessary waste.
Connecting rod 3 is provided between cross bar 1, connecting rod 3 includes cross bar 2 31, the internal structure and cross bar of cross bar 2 31
One 2 is identical, and the both ends of cross bar 2 31 are slidably fitted with sliding sleeve 32 respectively, and several through-holes 33 are offered on sliding sleeve 32.
Link block 5 for fixed connecting rod 3 is installed, link block 5 is internally provided with pedestal 51, base on support rod 1
The surrounding of seat 51 is provided with small lugs 52 compatible with through-hole 33.Wherein one end of small lugs 52 extends to the outer of link block 5
Side.Spring 2 53 is connected between the other end and pedestal 51 of small lugs 52.By spring 2 53 small lugs 52 are prolonged always
The outside of link block 5 is extended to, small lugs 52 are passed through through-hole 33 when link block 5 is inserted in sliding sleeve 32, made using spring 2 53
Small lugs 52 can pass through through-hole 33 and extend to the outside of sliding sleeve 32, so that removing more convenient.
Using being used cooperatively for spring 2 53 and small lugs 51, small lugs 51 are passed through into sliding sleeve 32, reaches fixed effect, makes
Connecting rod 31 connects more convenient with cross bar 1, play the role of being easy for installation and removal.
Working principle: in use, when protective fence is hit, the movement of baffle 41 in air bag 4 squeezes spring 1, into
Row damping, buffering, when the impact force being subject to is excessive, baffle 41 opens up to be broken at groove 45, and the baffle 41 of breaking part is to pressure
Contracting air bottle 42 is hit, and compressed air bottle 42 is punctured, the air of compression, which releases, is full of air bag 4, delays to impact
Punching.
In conclusion the site construction protective fence, by opening up groove 45 on baffle 41, so that baffle 41 is hit when splitting
Compressed air bottle 42 is punctured, compressed air passes through baffle 41 to improve the buffer capacity of protective fence full of air bag 4
With spring 1 is connected in pedestal 43, improve the impact resistance of protective fence, protective fence avoided to be caused to compress by minor impact
Air bottle 42 ruptures, and causes unnecessary waste.
Also, using being used cooperatively for spring 2 53 and small lugs 51, small lugs 51 are passed through into sliding sleeve 32, reach fixed effect
Fruit plays the role of being easy for installation and removal so that connecting rod 31 connects more convenient with cross bar 1.
