Abstract
An excavator armrest box locking device is characterized in that: a dowel is arranged in the locking device, the dowel cover in the sleeve is propped up by the flexibility, the head of the dowel is positioned at the upper part of the lacking core and is propped against the operation rod to stop the clockwise rotating in the locking place, and is propped against the place of the operation rod that can stop the controrotating, so as to make the operation rod is contacted with the different position of the operation rod by the dowel pushed out by the flexible force whatever the operation rod is positioned at the locking position or the unlocking position to stop the movement of the operation rod. The utility model has the advantages that: can effectively solve the problems that the lock buckle is struck to the hanging hook when maintain, and the problem that can not adjust after clock to death. In the lifting and the landing process of the operation rod, using the locking device to control the open-close of the lock, to realize the freely locking of the armrest box, and add an air spring can realize the automatic lifting, has a high automatic extent, and a simple operation.
Description
Technical field
The utility model relates to a kind of excavator armrest box locking device.
Background technology
The excavator armrest box retaining mechanism of domestic production at present and use, its locking are to be realized by the hook of off-centre.It is attractive in appearance ceaselessly to produce noise, profile in motion yet.Be to realize because hook departs from, can produce noise, also stuck phenomenon may occur simultaneously by each other active force.Be again nonadjustable when stuck, at this time need to increase a people and finish.Make operation become complicated.
Summary of the invention
When the purpose of this utility model just provides a kind of solution maintenance, the shock problem of snap close and hook; The nonadjustable problem in stuck back.In the lifting and landing of control stick rotation, by retaining mechanism, come the folding of control lock, realize freely locking of armrest box, and the adding air spring can be realized automatic rising, automatic degree height, excavator armrest box locking device simple to operate.
The utility model is that the locking device that comprises control stick, lock core, lock body, rotation pedestal is installed on the armrest box housing, in locking device, be provided with pin, guide is ejected by elastic force in sleeve, the head of pin is positioned at the top of lock core, withstand on the control stick prevention when being in locked position and clockwise rotate, when unlocked position, withstand on the position that the control stick prevention rotates counterclockwise, make when no matter control stick is in locked position or unlocked position, all join in different positions, stop the motion of control stick with the pin of releasing by elastic force.
The utility model has the advantages that in the time of effectively to solve maintenance the shock problem of snap close and hook; The nonadjustable problem in stuck back.In the lifting and landing of control stick rotation, by retaining mechanism, come the folding of control lock, realize freely lock of armrest box, and add air spring and can realize automatic rising, automatic degree height, simple to operate.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the structural representation of the utility model when non-locking state.
Accompanying drawing 2 is the utility model structural representations when locking state.
Accompanying drawing 3 is the utility model is installed air spring on housing structural representations.
The specific embodiment
Present embodiment comprises control stick 1, pin 2, sleeve 3, adjusting nut 4, lock core 5, lock body 6, rotation pedestal 7, air spring 8, snap close 9.
The locking device that comprises control stick 1, lock core 5, lock body 6, rotation pedestal 7 is installed on the armrest box housing, in locking device, be provided with pin 2, pin 2 is enclosed within the sleeve 3 and is ejected by elastic force, the head of pin 2 is positioned at the top of lock core 5, withstands on control stick 1 prevention when being in locked position and clockwise rotate, withstand on the position that control stick 1 prevention rotates counterclockwise when unlocked position.Control the locking state of lock body 6 and snap close 9 by rotating control stick 1.
Described elastic force is in sleeve 3 spring to be installed, and an end of spring is connected with pin 2.One end of pin 2 stretches out from sleeve 3, and the screw thread position on it is connected with adjusting nut 4, and rotation adjusting nut 4 is in order to the overhang of adjusting pin 2 front ends.
Air spring 8 is installed on the armrest box housing, and the other end of air spring 8 is fixed on the Connection Block.
Fig. 1 is the lock state after armrest box promotes, and control stick 1 is fixed on rotation pedestal 7 and rotatable, and pin 2 can slide in sleeve 3.When the non-locking state of armrest box, control stick 1 is by rotation pedestal rotary lifting, promote lock core 5, because lock core is a moving lock mechanism in this lock core 5 and the lock body 6, when being in, lock core 5 will stop lock core enforcement locking function in the lock body 6 this moment, and sell 2 this moment in the sleeve 3 by past interior propelling, thus owing to being with spring, pin 2 can not have the propelling that ends, thus make pin 2 block the top maintenance current state of control stick 1.
Fig. 2 is the lock state after armrest box descends, after control stick 1 descends by the rotation of rotation pedestal, lock core 5 is not being blocked in the top of control stick 1, lock core 5 is returned to original position by the spring of lock body 6 inside, lock body 6 regains locking function, thereby locking snap close 9 is sold 2 tops of blocking control stick 1 again simultaneously.
Fig. 3 has the installing hole that is drilled with air spring 8 on the housing of armrest box retaining mechanism, air spring 8 other ends are fixed on supporting base, load onto air spring 8 after, when control stick 1 up promotes lock body 6 in case the snap close below breaking away from can be realized automatic rising.
