Machine 3, the avris of installation casing 1 are provided with pushing-off the wagons bar 4, and one end of pushing-off the wagons bar 4 is fixed with connecting rod 5, connecting rod 5 it is outer
Side is equipped with connection sleeve 6, and the end point for connecting sleeve 6 is provided with non-slip mat 7, and the lower section of pushing-off the wagons bar 4 is equipped with protection
Block 8, and the end point of pushing-off the wagons bar 4 is connected with fixed link 9, and the inside of fixed link 9 is provided with limit plate 10, support base 11
It is mounted on the avris of fixed link 9, and the inside of support base 11 is provided with active column 12, rubber pad 13 is adhered to active column 12
Bottom, and the middle position of active column 12 is equipped with link block 14, and the top and bottom of link block 14 are respectively arranged with
Push rod 15 and lower push-rod 16, and the centre of upper push-rod 15 and lower push-rod 16 is provided with solution cavity 17, and the bottom of lower push-rod 16
It is connected with compressed spring 18；
The middle position of pushing-off the wagons bar 4 is connected by elastic hinge, and the protective block 8 of 4 bottom of pushing-off the wagons bar is hardhead sponge material,
When pushing-off the wagons bar 4 is hit by the external world, the middle position of pushing-off the wagons bar 4 be can rotate, and can be constantly in when not stressing with always
On line, it can reduce to extraneous rammer and the damage of itself, the protective block 8 of sponge material can hit to avoid active column 12
Pushing-off the wagons bar 4 is impaired；
Connecting rod 5 and connection sleeve 6 form slide construction, and the one end for connecting sleeve 6 extends to the inside of installation casing 1, and
And connection sleeve 6 and non-slip mat 7 are heat bonding, connecting rod 5 and connection sleeve 6 are arcuate structure, and the arc core of the two and are blocked
The rotation center of circle of car bumper bar 4 coincides, and the end point of pushing-off the wagons bar 4 and connecting rod 5 be welded to connect, pushing-off the wagons bar 4 to
Upper rotation drives connecting rod 5 to slide in connection sleeve 6, and such connecting rod 5 and connection sleeve 6 have the rotation of pushing-off the wagons bar 4
The junction of restricted effect, connecting rod 5 and connection sleeve 6 is provided with non-slip mat 7, and when mechanical disorder, non-slip mat 7 is increased
Resistance to sliding, the pushing-off the wagons bar 4 for turning to half, which will not land rapidly, pounds vehicle, increases safety when use；
Limit plate 10 and active column 12 be magnetic connection, and limit plate 10 looks up the arc-shaped structure of angle, and activity is vertical
Column 12 forms rotational structure by support base 11 and pushing-off the wagons bar 4, and when active column 12 and ground are in plumbness, activity is vertical
The avris and limit plate 10 of column 12 are attracting, and the position vertical to active column 12 has fixed function, the limit plate of arcuate structure
10 can preferably fit with active column 12；
There are gaps for the top of link block 14 and active column 12, and the bottom of link block 14 and active column 12 are fixed connect
It connects, had not only facilitated movement of the upper push-rod 15 in link block 14 in this way, but also extruding of the lower push-rod 16 to compressed spring 18 will not be interfered
Operation, increases the integrally-built stability of active column 12；
Upper push-rod 15 and lower push-rod 16 form stretching structure with link block 14, and the section that the two is is T-shaped knot
Structure, and inner wall of the edge of upper push-rod 15 and lower push-rod 16 with link block 14 fits closely, compressed spring 18 and activity
Column 12 and lower push-rod 16 are to be welded to connect, and the centre of active column 12 is connected by link block 14, when rubber pad 13 with
When ground struck, upper push-rod 15 is driven to move in link block 14 downwards, lower half of the solution in solution cavity 17 to link block 14
Part is flowed, and plays a hydraulic effect, and then compressed spring 18 is driven to be squeezed in 12 bottom of active column, vertical to activity
The landing of column 12 has buffer function, alleviates vibration and noise, and extend the service life of device.
Working principle: it when using estate management service parking lot vehicle automatic railing, according to Fig. 1-2, revolves first
Rotating motor 3 can control the rotation of pushing-off the wagons bar 4, and when there is vehicle to pass through, pushing-off the wagons bar 4 is rotated up, and generate to connecting rod 5
Pulling force, and then connecting rod 5 is driven to slide in connection sleeve 6, one end of connection sleeve 6 extends to the inside of installation casing 1, side
Just storage also increases the aesthetics of device, and connecting rod 5 and connection sleeve 6 are arcuate structure, and connecting rod 5 and connector sleeve
The rotation center of circle of the arc core and pushing-off the wagons bar 4 of cylinder 6 coincides, the rotation of such connecting rod 5 and connection sleeve 6 to pushing-off the wagons bar 4
With limitation and supporting role, the junction of connecting rod 5 and connection sleeve 6 is provided with the non-slip mat 7 of rubber material, when machine event
When barrier, non-slip mat 7 increases the resistance to sliding of connecting rod 5, has slowed down the sliding of the speed and connecting rod 5 of the whereabouts of pushing-off the wagons bar 4
Speed, the pushing-off the wagons bar 4 for turning to half in this way will not pound vehicle because of the uncontrolled rapid landing of mechanical disorder, increase
Safety when use, when pushing-off the wagons bar 4 is hit by the external world, the middle position of pushing-off the wagons bar 4 is connected by elastic hinge,
With restorative well, it therefore can rotate when pushing-off the wagons 4 stress of bar, can be constantly on same straight line when not stressing, it can
Reduce to extraneous rammer and the damage of itself；
It can be rotated between the top and support base 11 of active column 12 according to Fig. 1 and Fig. 3-5 when pushing-off the wagons bar 4 lands,
When pushing-off the wagons bar 4 turns to horizontality, active column 12 and ground are in plumbness, the avris of active column 12 and limit
Plate 10 is attracting, has fixed function to the position of 12 plumbness of active column, active column 12 and the position of ground face contact are set
Be equipped with rubber pad 13, can reduce active column 12 directly with ground face contact is impaired generates noise and vibration, when rubber pad 13 with
When ground struck, upper push-rod 15 is driven to move downward in link block 14, pushes the solution in solution cavity 17 to link block 14
Lower half portion flowing drives the position decline of lower push-rod 16, and then generates pressure to compressed spring 18 by the bottom of lower push-rod 16
Power plays a hydraulic effect in the internal contraction of active column 12, and droping to ground to active column 12, there is buffering to make
With, alleviate vibration and noise, and extend the service life of device, when pushing-off the wagons bar 4 rise when drive active column 12
It is rotated between support base 11, active column 12 can be folded to and 4 phase of pushing-off the wagons bar when pushing-off the wagons bar 4 turns to vertical state
Fitting, it is impaired that the protective block 8 of sponge material can hit pushing-off the wagons bar 4 to avoid active column 12, while increasing pushing-off the wagons bar 4
The stability unfolded and folded.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
