The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Sun-blind device as shown in Figure 1, be arranged on engineering truck, in operator's compartment and/or operator's compartment as Spiral digging machine and hoisting crane, sun-blind device comprises pilot bar 5, strut bar 3 and cord 4, one end of pilot bar 5 is fixedly installed in operator's compartment or operator's compartment, as is placed in an end of Abat vent scroll, and the other end is unsettled or be fixedly installed, strut bar 3 is sheathed on pilot bar 5, and can move around on pilot bar 5.Particularly, offer pilot hole on strut bar 3, the shape of the shape of pilot hole and pilot bar 5 is complementary, one end of cord 4 is fixed on strut bar 3, the other end of cord 4 is placed in spool, and along with strut bar 3 moving around on pilot bar 5, cord 4 also stretches out thereupon or retracts.
In technique scheme, pilot hole can be opened on the earrings 2 of strut bar 3, earrings 2 is arranged on strut bar by pawl, in one embodiment, be provided with damping structure in pilot hole, particularly, pilot hole is located in the earrings 2 of strut bar 3 terminations, damping structure is damping ring 1, as shown in Figures 2 and 3, damping ring 1 comprises damping ring body 11 and is located at the damping ring head 12 at damping ring body 11 two ends, and the shape of damping ring 1 can be varied, do not do concrete restriction at this, can play the increase rubbing effect and get final product.The material of damping ring 1 can increase the material of friction force between pilot bar 5 and strut bar 3 for rubber etc., and coordinating between damping ring 1 and pilot hole is interference fit.Earrings 2 can be the integral type structure, also can split-type structural,, because split-type structural is conducive to Assembly ﹠Disassembly damping ring 1, can not damage the integraty of damping ring 1, therefore, preferred split-type structural.
In another kind of embodiment, damping ring 1 is sheathed on pilot bar 5, the quantity of damping ring 1 can be for a plurality of, strut bar 3 between two damping rings 1, when needs movable support bar 3, first moves the damping ring 1 that is positioned at strut bar 3 one sides, after damping ring 1 is moved to the position that needs, again strut bar 3 is moved to relevant position, the friction force between damping ring 1 and pilot bar 5, can effectively prevent the movement of strut bar 3.
Need to prove, the sun-blind device of said structure, as adopt two pilot bars 5, the structure of strut bar 3 between two pilot bars 5, all can arrange damping ring 1 in two of strut bar 3 pilot holes.In addition, also the guide spring sheet can be set on earrings 2, more smooth and easy when cord 4 is pulled out, the resistance when increasing simultaneously cord 4 and furling.
In addition, also can offer chute on pilot bar 5, strut bar 3 can move around along chute.When adopting sliding groove structure, can consider at the friction force damping structure that is provided on chute increasing between strut bar 3 and chute.
The sun-blind device of said structure has following advantage:
At first, cord 4 can hover over optional position.The sun-blind device of said structure, be provided with damping ring 1 on pilot bar 5 and/or in the pilot hole of strut bar 3, damping ring 1 has increased the friction force between strut bar 3 pilot holes and pilot bar 5, strut bar 3 can hover over optional position as required, because an end of cord 4 is fixed on strut bar 3, therefore cord 4 can rest on optional position, efficiently solves the problem that hovers over optional position that cord 4 can not be firm, has alleviated the work capacity of operator or chaufeur.
Secondly, simple in structure, easily operation.The sun-blind device of said structure, only need to arrange in pilot hole and/or in pilot bar damping ring 1, and directly movable support bar 3 can realize that just cord 4 hovers over optional position, and therefore, structure is comparatively simple, and easily operation, is easy to realize.
Again, with low cost, be easy to promote.The sun-blind device of said structure, the damping ring 1 that only need increase one or more elastomeric materials just can solve cord 4 and can not hover over the problem of optional position, and therefore, cost is comparatively cheap, easily promotes the use.
On the other hand, the utility model also proposes a kind of engineering truck, and engineering truck comprises operator's compartment and/or operator's compartment, and is provided with sun-blind device as above in operator's compartment and/or operator's compartment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
