The utility model solves the technical scheme that its technical problem adopted: a kind of combined harvester is used the Concealable cat ladder; Comprise the cat ladder body, it is characterized in that described cat ladder bodies top along continuous straight runs is fixed with a fixed disk; The top of fixed disk is provided with a flat board; Flat board vertically is respectively equipped with bearing pin sleeve and shaft sleeve through being bolted on the frame on the flat board, on fixed disk, be respectively equipped with through hole with bearing pin sleeve and the corresponding position of shaft sleeve; Described flat board is fixed on the fixed disk through the rotating shaft in the shaft sleeve, is provided with bearing between rotating shaft and the shaft sleeve; Along continuous straight runs also is fixed with a plate through bearing pin on the described shaft sleeve, and an end of connecting plate is fixed with a compression leg, and the other end is fixed with handle; Be provided with bearing pin in the described bearing pin sleeve, an end of bearing pin is provided with through hole and is enclosed within on the handle, and the other end of bearing pin becomes to taper, inserts in the through hole corresponding on the fixed disk; Also be provided with a manual lock handle on the described cat ladder body, described manual shank of the key is through frame and cat ladder body.
The beneficial effect of the utility model is: through the fixing cat ladder of a plurality of locking devices, strengthen the stability of cat ladder, can rotate cat ladder through rotating shaft simultaneously and make it be hidden in the vehicle frame below, make compact overall structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 cat ladder body, 2 fixed disks, 3 flat boards, 31 bearing pin sleeves, 32 shaft sleeves, 4 frames, 5 rotating shafts, 6 connecting plates, 7 compression legs, 8 handles, 9 bearing pins, 10 manual shank of the keys
Embodiment
As shown in Figure 1; A kind of combined harvester is used the Concealable cat ladder, comprises cat ladder body 1, and described cat ladder body 1 top along continuous straight runs is fixed with a fixed disk 2; The top of fixed disk 2 is provided with one dull and stereotyped 3; Dull and stereotyped 3 through being bolted on the frame 4, vertically is respectively equipped with bearing pin sleeve 31 and shaft sleeve 32 on the flat board 3, on fixed disk 2, is respectively equipped with through hole with bearing pin sleeve 31 and shaft sleeve 32 corresponding positions; Described dull and stereotyped 3 are fixed on the fixed disk 2 through the rotating shafts 5 in the shaft sleeve 32, are provided with bearing between rotating shaft 5 and the shaft sleeve 32; Along continuous straight runs also is fixed with a plate 6 through bearing pin on the described shaft sleeve 32, and an end of connecting plate 6 is fixed with a compression leg 7, and the other end is fixed with handle 8; Be provided with bearing pin 9 in the described bearing pin sleeve 31, an end of bearing pin 9 is provided with through hole and is enclosed within on the handle 8, and the other end of bearing pin 9 becomes to taper, inserts in the through hole corresponding on the fixed disk 2; Also be provided with a manual lock handle 10 on the described cat ladder body 1, described manual shank of the key 10 is through frame 4 and cat ladder body 1.
During use, with flat board 3 through being bolted to frame 4 belows, during locking; Handle 8 is pressed down; Bearing pin 9 is inserted in the through hole corresponding on the fixed disk 2, and also can insert manual shank of the key 10 cat ladder bodies 1 on corresponding hole in for better fixedly cat ladder body 1 this moment; Realize locking, improve the stability of cat ladder body 1.Push downwards or when trampling compression leg 7; Connect the other end perk of the connecting plate 6 of compression leg 7; The bearing pin 9 that drive is enclosed within on the handle 8 vertically moves up, and extract manual shank of the key 10 this moment, only leans on rotating shaft 5 to link between the cat ladder body 1 and dull and stereotyped 3; Because rotating shaft 5 is passed through bearing fixing in shaft sleeve 32, so cat ladder body 15 axial directions rotation around the shaft.
