The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.
Below with reference to accompanying drawing, embodiments of the invention are done to concrete explaination.
A kind of length-adjustable hound of the embodiments of the invention as shown in Fig. 1 to 4, comprises screw mandrel joint 1, outer tube 9 and clutch component 6.Clutch component 6 comprises end cap 5 and some slide blocks 60.End cap 5 is provided with through hole, and outer tube 9 is provided with pilot hole 9A.One end of screw mandrel joint 1 is sheathed in through hole and pilot hole 9A successively, and can slide along through hole and pilot hole 9A.
On some slide blocks 60, be equipped with guide pillar 61.End cap 5 is provided with some locating slot 5C, in some locating slot 5C, is equipped with separating end and closing end.Guide pillar 61 is placed in locating slot 5C, and can slide along locating slot 5C.
On one end of some slide blocks 60 and screw mandrel joint 1, be respectively equipped with the first locking mechanism and the second locking mechanism that cooperatively interact.When the guide pillar 61 of some slide blocks 60 is all placed in the separating end of locating slot 5C, some slide blocks 60 are fixed by the first locking mechanism and the second locking mechanism with one end of screw mandrel joint 1; When the guide pillar 61 of some slide blocks 60 is all placed in the closing end of locating slot 5C, some slide blocks 60 and screw mandrel joint 1 matched in clearance.
Embodiments of the invention adopt the separated and locking screw mandrel joint of separation assembly, collapsing length that can quick adjustment screw mandrel joint, and process is simple and convenient, and save trouble and labor saves time.
In an embodiment of the present invention, preferred orientation groove 5C is shaped as arc, and around the through hole of end cap 5.Separating end and closing end are placed in respectively one end of arc positioning groove 5C, and the distance of separating end and through hole is greater than the distance of closing end and through hole.And the quantity of preferred orientation groove 5C and slide block 60 is 3,3 slide blocks 60 coordinate and form a manhole when closure.
And preferably the first locking mechanism and the second locking mechanism are the screw thread cooperatively interacting.
As shown in figs. 1 and 2, in an embodiment of the present invention, the end face on outer tube 9 has several keyways 9C, and for stationary positioned key 7, positioning key 7 can be slide block 60 guiding, makes slide block 60 do rectilinear motion along positioning key 7.
As shown in Fig. 1 and 3, in an embodiment of the present invention, clutch component 6 is by slide block 60, guide pillar 61, flexible member, be preferably the first spring 62 and adjustment screw 63 compositions, under the effect of adjustment screw 63 and the first spring 62, guide pillar 61 stretches out from the hole of slide block 60 and enters in the gathering sill 5C of end cap 5.
As Figures 1 and 4, in an embodiment of the present invention, end cap 5 is negative and positive pairings with the mating interface of outer tube 9, when the first baffle ring 5B of end cap 5 slips into the second interior caulking groove 9E from the indentation, there of outer tube 9 interfaces, rotating end cap 5 makes the first baffle ring 5B of end cap 5 and the second baffle ring 9D of outer tube 9 overlapping (now the baffle ring 5B of end cap 5 is in the second interior caulking groove 9E of outer tube 9, and the baffle ring 9D of outer tube 9 is in the first interior caulking groove 5A of end cap 5).When the second baffle ring 9D of the first baffle ring 5B of end cap 5 and outer tube 9 is when overlapping, slide block 60 slides into closing end along the path of the gathering sill 5C of end cap 5, and now the guide pillar 61 of one of them slide block 60 springs in the locating hole 5D of end cap 5.And combination as shown in Figures 5 and 6, the outside of end cap 5 has a spring capping 2 keying button 3 and the second spring 4 to be enclosed in to the top of the locating hole 5D of end cap 5.
And in conjunction with as shown in Figure 7, when slide block 60 is closed, lock screw 8 screws in the locking screw thread hole 9B of outer tube 9.When lock screw 8 screws out, press and open and close after button 3 rotating end cap 5, slide block 60 is radially separated, after the screw thread of slide block 60 and the disengaging of the screw thread of screw mandrel joint 1, screw mandrel joint 1 can be in the pilot hole 9A of outer tube 9 free-extension.
Adjustment process: when needs regulate dozer cutting angle, the lock screw 8 of back-outing, press when opening and closing button 3 and be rotated counterclockwise end cap 5(when end cap 5 is threaded to the position of another lock screw 8, the thread separation of slide block 60 completely and on screw mandrel joint 1), regulate the collapsing length (can and roll oil cylinder by lift cylinder controls) of hound upper screw rod joint 1.Adjust to after the hound length needing, end cap 5 to the guide pillar 61 that turns clockwise springs in the locating hole 5D of end cap 5.Tighten lock screw 8.
In embodiments of the invention, also comprise a kind of bulldozer, be provided with length-adjustable hound described above.Because above-mentioned length-adjustable hound has above-mentioned technique effect, therefore, the bulldozer that is provided with this length-adjustable hound also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
Above specific embodiments of the invention be have been described in detail, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and alternative also all among category of the present invention.Therefore, equalization conversion and the modification done without departing from the spirit and scope of the invention, all should contain within the scope of the invention.
