Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
Embodiment 1, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of protection arm having regulatory function, including protection arm is solid
Determine frame 1, protection arm fixed frame 1 is main holder and main fixed component, is mounted on industrial vehicle.Protection arm is solid
Determine to be generally provided with corresponding digital keys, startup, stop button etc. on frame 1.
Mounting base 2 is installed, mounting base 2 is connect with arm body 3 on protection arm fixed frame 1.And arm body 3 is simultaneously further through overturning
Self-locking device 5 is connect with protection arm fixed frame 1.
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.Arm body 3 is equipped with cushion pad
31, buffering on the one hand is provided when closing, buffering is also provided when on the other hand conflict with worker's body.Arm body 3 is logical
It crosses vertical connecting shaft 4 to be rotatablely connected with mounting base 2 so that arm body 3 mounting base 2 can open and close in the horizontal direction relatively.
As shown in figure 3, mounting base 2 is not to be fixedly connected, but mounting base 2 is equipped in water with protection arm fixed frame 1
Square to extension connecting shaft 24, connecting shaft 24 and protection arm fixed frame 1 be rotatablely connected, so that entire mounting base 2 can be
It is rotated on vertical direction, to drive entire arm body 3 to be rotated in vertical direction.
When needing to lock the flip angle of mounting base 2 and arm body 3 in the vertical direction, it is necessary to catch means 7 are overturn,
Specifically, can be offered through slot in the position on the lower of mounting base 2, it is logical that overturning catch means 7 may be mounted at this
It crosses in slot.As shown in figure 4, overturning catch means 7 include the high-order positioning bead 711 and low level positioning bead 712 of spring 72 and both ends,
Two positioning beads 71 are all acted on by the outside elastic force of spring 72.When entire mounting base 2 is rotated in place, corresponding positioning bead 71
It is popped up, is stuck in corresponding location hole 11 by elastic force, mounting base 2 is prevented to continue to rotate, complete position and fix.
In the technical scheme, location hole 11 includes two, and the first from left right side is located at the both sides of mounting base 2, is opened in protection
On arm fixed frame 1.The two location holes 11 are respectively high-order location hole 111 and low level location hole 112, are located on different height.
When entire mounting base 2 and arm body 3 rotate to eminence, spring 72 ejects high-order positioning bead 711, blocks and arrive high-order location hole
111.When entire mounting base 2 and arm body 3 rotate to lower, spring 72 ejects low level positioning bead 712, blocks and arrive low level positioning
Hole 112.
