Abstract
The utility model discloses a turning mechanism for liftable control boxes of mini-excavators, which belongs to the field of mechanical turning. The turning mechanism comprises a box, a turning support, a limit block, a fixed support limited shaft, a fixed support, a safety switch, a rotary shaft, a turning handle and an air spring, the turning support is connected with the fixed support through the rotary shaft, the safety switch is mounted at the articulating joint between the fixed support and the turning support, one end of the air spring is fixed on the fixed support, the other end of the air spring is fixed on the turning support, the turning handle and the rotary shaft are welded together, the turning handle is connected with the limit block through a pin, the limit slot of the limit block is connected with the fixed support limited shaft, and the box is mounted on the turning support. The turning mechanism has the advantages that: the turning stress is uniform, turning is flexible, the locking force of the air spring can be overcome, the structure is simple, the arrangement is reasonable, and the shape is attractive.
Description
Technical field
The utility model relates to a kind of rotating mechanism, specifically is the rotating mechanism that a kind of mini-excavator can start operation panel.
Background technology
At present, little tonnage excavator causes driver's difficult problem of getting on or off the bus because of cab space restriction, and little tonnage digging machine operation panel adopts the device that can start.Can start operation panel at present all adopts stopping means to add the form of spring; Existing stopping means all adopts arc, and the shortcoming of this device is a complex structure, spring force is required big; And require the operation panel below that the activity space of arc is arranged, do not meet the requirement of saving cab space.
Summary of the invention
To the problem that above-mentioned prior art exists, the rotating mechanism that the utility model provides a kind of mini-excavator can start operation panel, simple in structure, rationally distributed, handsome in appearance, save cab space, overcome the locked power of air spring, operation is easily.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of mini-excavator can start the rotating mechanism of operation panel; Comprise: casing, swinging mounting, limited block, fixed support limit shaft, fixed support, safety switch, turning cylinder, turning handle, air spring, swinging mounting links together through turning cylinder and fixed support, and safety switch is installed in the position of articulating point of fixed support and swinging mounting; Air spring one end is fixed on the fixed support; The other end is fixed on the swinging mounting, and turning handle and turning cylinder weld together, and is connected with limited block through pin; The stopper slot of limited block is connected with the fixed support limit shaft, and casing is installed on the swinging mounting.
The beneficial effect of the utility model is: spacing and damping unit all places in the operation panel, does not take the operation panel space outerpace.Air spring and limited block symmetric arrangement are rotated and stressedly evenly rotated flexibly, and be locked reliable.The component of air spring capable of using self and limited block are realized self-locking, and be simple in structure, rationally distributed, handsome in appearance.Because it is longer to lift the arm of force of power of handle,, operate light so just can overcome the locked power of air spring with very little power.

Fig. 3 is the front view of the utility model.
Among the figure: 1, casing, 2, swinging mounting, 3, limited block, 4, limit shaft, 5, fixed support, 6, safety switch, 7, turning cylinder, 8, turning handle, 9, air spring.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As shown in Figure 1, a kind of mini-excavator can start the rotating mechanism of operation panel, comprises casing 1, swinging mounting 2, limited block 3, limit shaft 4,5 fixed supports 5, safety switch 6, turning cylinder 7, turning handle 8, air spring 9; Fixed support 5 is installed on the other base plate of driver's cabin seat; Swinging mounting 2 links together through turning cylinder 7 and fixed support 4, and safety switch 6 is installed in the position of articulating point of fixed support 4 and swinging mounting 2, and air spring 9 one ends are fixed on the fixed support 5; The other end is fixed on the swinging mounting 2; Simulate through strict calculating the installation site, and turning handle 8 welds together with turning cylinder 7, and be connected with limited block 3 through pin; The stopper slot of limited block 3 is connected with fixed support limit shaft 4, and casing 1 is installed on the swinging mounting 2.
When operation panel is in when starting the position, the stroke of air spring 9 reaches capacity, and the restriction operation panel continues upset.Move turning handle 8 downwards, turning handle 8 is that hinge rotates with turning cylinder 7, and swinging mounting 2 rotates with the hinge of swinging mounting 2 and fixed support 5 simultaneously; Air spring 9 rotates and elongation gradually with two hinges of oneself, and fixed support limit shaft 4 slides in the scope of limited block 3 stopper slots, when turning in air spring 9 compression processes at the shortest; Begin elongation, realize self-locking, be rotated further handle 8 to below this moment; Limited block 3 reaches rotational limitation, the rotation of the stopper slot of limited block 3 and fixed support limit shaft 4 common limit rotation supports 2, further self-locking; In pressing process, safety switch 6 connection that is depressed.Otherwise, upwards lift turning handle 8 operation panel swinging mountings 2 and rotate thereupon, reach the elongation limit until air spring 9.In starting process, safety switch 6 breaks off, and system can not work.
