Specific implementation mode
Below in conjunction with attached drawing, invention is further described in detail.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
Embodiment 1, as shown in Figure 1, Figure 2 and Figure 3, a kind of protection arm with limit function suitable for industrial vehicle, packet
Fixed frame containing protection arm 1, protection arm fixed frame 1 are main holder and main fixed component, are mounted on industrial vehicle
On.Corresponding digital keys, startup, stop button etc. are generally provided on protection arm fixed frame 1.
Mounting base 2 is installed, mounting base 2 includes fixed frame interconnecting piece and arm body interconnecting piece 21, arm on protection arm fixed frame 1
Body interconnecting piece 21 can be vertical with 1 direction of protection arm fixed frame, i.e., front-rear direction extends, and arm body interconnecting piece 21 is used for and arm body 3
Connection.And arm body 3 is connect further through overturning self-locking device 5 with protection arm fixed frame 1 simultaneously.
Specifically, arm body 3 is two sets, the first from left right side is located at both sides.It overturns self-locking device 5 and includes at least three parts,
It is hinge joint 1, catch bar 52 and hinge joint 2 53 respectively.Wherein, catch bar 52 can use gas spring, for lasting
Uniform thrust.Hinge joint 1 and protection arm fixed frame 1 are hinged, and hinge joint 2 53 is hinged with mounting base.It is opened in arm body 3
During, when the tie point of arm body 3 and the mounting base 2, hinge joint 1 and 2 53 three of hinge joint are in the horizontal plane
Projection is located along the same line, and just reaches the dead point state of self-locking at this time, and arm body 3 will not be pushed easily again.This opening angle
For degree generally between 30 ° -60 °, the open angle corresponding to this self-locking state is also holding angle of the arm body 3 in operation,
Operator just stands the operation in the guard interval that two inclined arm bodies 3 are constituted.When worker needs to continue opening arms body 3,
More forcibly rotating arm body 3, the angle that arm body 3 crosses dead point self-locking is then needed to continue to flip outward.
As shown in figure 3, when arm body 3 continues to outwardly open, the rotation abutting portion 34 of 3 tail end of arm body can connect with arm body
The resistance surface 212 in 21 outside of socket part contradicts, and due to conflict herein, arm body 3 can not continue to flip outward, and reach mechanical position limitation
Effect.Conversely, when arm body 3 is inwardly overturn, mounting base 2 is equipped with close to switch 6, can sense the close of arm body 3, when
Arm body 3 can also control the deceleration and closing of catch bar 52 close to a certain extent.Arm body 3 is equipped with cushion pad 31, on the one hand
Buffering is provided when closing, buffering is also provided when on the other hand conflict with worker's body.
Mounting base 2 includes the arm body interconnecting piece 21 for being connect with arm body 3, and arm body interconnecting piece 21 is equipped with for connecting shaft 4
By through hole 22, arm body interconnecting piece 21 is arc-shaped, and arm body 3 is equipped with match arc with 21 form fit of arm body interconnecting piece
Slot 33.Arm body 3 is equipped with rotating junction 32, and rotating junction 32 is connect by connecting shaft 4 with arm body interconnecting piece 21, and rotation connects
Socket part 32 is equipped with transition cambered surface.
Further, when inside overturning, arm body blocking portion 23 is equipped in mounting base 2, on arm body blocking portion 23
Equipped with gasket 231 flexible, and arm body blocking portion 23 and gasket 231, it is respectively positioned on close to the outside of switch 6.Arm in the other side
When body 3 is inwardly overturn, the signal of deceleration or braking can be provided close to switch 6, when arm body 3 leans on proximal arm body blocking portion 23
When, it can finally be blocked by arm body blocking portion 23 by gasket 231 flexible into row buffering, complete limit, avoid excessively overturning.
