Description
Technical field
The utility model belongs to the farm machinery technical field, is specifically related to a kind of armrest frame of mini-tiller.
Background technology
Mini-size tillage machine is take small diesel engine or gasoline engine as power, has lightweightly, and the characteristics such as volume is little, and is simple in structure are widely used in the nonirrigated farmland, paddy field, orchard on Plain, mountain area, hills etc.Mini-size tillage machine generally includes the parts such as cutter, engine, transmission case, holder, arm-rest frame, and wherein, arm-rest frame one end is connected on holder, and the other end is provided with the handrail pole that grips for the people.In mini-size tillage machine when work,, operating personnel hold the direction that handrail props up the pole pair mini-size tillage machine and control.Because operating personnel have different height, when must causing the part operation personnel operation, fixing arm-rest frame height more requires great effort.In order to address this problem, the main mode of mill tooth or pull-rod spring location that adopts is regulated with the height of realizing arm-rest frame at present, still, the common complex structure of the governor motion of these arm-rest frames, complex operation during use relates to during manufacturing that part is many, cost is high.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of arm-rest frame of mini-size tillage machine, and this arm-rest frame is simple in structure, can realize fast, easily that the height of arm-rest frame is regulated.
For achieving the above object, the technical solution adopted in the utility model is: a kind of armrest frame of mini-tiller, comprise armrest seat and handrail pole, and it is characterized in that: be respectively equipped with the axial end-toothed disc of trunnion axis on described armrest seat and handrail pole; The interlaced engagement of end-toothed disc on armrest seat and handrail pole, and adjustable fixing by the lifting lock shaft that runs through end-toothed disc; One end of described lifting lock shaft is threaded with an end-toothed disc at edge.
Rotate the lifting lock shaft, intermeshing end-toothed disc is unclamped, the distance between end-toothed disc is rocked handrail pole to the height that needs, then is turned tight lifting lock shaft greater than the end-toothed disc tooth depth, has namely completed the height of the utility model armrest frame of mini-tiller and has regulated.
Useful technique effect of the present utility model is: in technical scheme of the present invention, adopt the mode of end-toothed disc engagement, the locking of lifting lock shaft, the existing height locking of end-toothed disc effect, again armrest seat and handrail pole are coupled together, and an end of lifting lock shaft is threaded with an end-toothed disc at edge, locking support point directly on end-toothed disc, need not to use other auxiliary retention portion parts.Therefore arm-rest frame of the present utility model by simple structure, has namely been realized the arm-rest frame height and has been regulated fast, easily.
Description of drawings
Fig. 1 is the structure chart of armrest frame of mini-tiller of the present utility model;
Fig. 2 is the cutaway view Amplified image of Fig. 1 lifting locking mechanism;
Fig. 3 is the cutaway view Amplified image of Fig. 1 steering lock structure.
In figure: 1-armrest seat, 2-handrail pole, 3-end-toothed disc, 4-lifting lock shaft, 5-lifting handle, the upper end-toothed disc of 6-, end-toothed disc under 7-, 8-steering lock mandrel, 9-steering handle, 10-sleeve.
Embodiment
Below the utility model is described in further detail by specific embodiment; but not in order to limit the utility model; all within the present invention spirit 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.
As depicted in figs. 1 and 2, armrest frame of mini-tiller of the present utility model comprises armrest seat 1 and handrail pole 2, it is characterized in that: be respectively equipped with the axial end-toothed disc of trunnion axis 3 on described armrest seat 1 and handrail pole 2; The interlaced engagement of end-toothed disc 3 on armrest seat 1 and handrail pole 2, and adjustable fixing by the lifting lock shaft 4 that runs through end-toothed disc 3; One end of described lifting lock shaft 4 is threaded with an end-toothed disc 3 at edge.
Armrest frame of mini-tiller of the present utility model, adopt the mode of end-toothed disc 3 engagements, 4 lockings of lifting lock shaft, the existing height locking of end-toothed disc 3 effect, again armrest seat 1 and handrail pole 2 are coupled together, and an end of lifting lock shaft 4 is threaded with an end-toothed disc 3 at edge, locking support point directly on end-toothed disc 3, need not to use other auxiliary retention portion parts.
When needs are adjusted the arm-rest frame height, rotate lifting lock shaft 4, intermeshing end-toothed disc 3 is unclamped, distance between end-toothed disc 3 is greater than end-toothed disc 3 tooth depths, rock handrail pole 2 to the height that needs, turn again tight lifting lock shaft 4, namely completed the height of the utility model armrest frame of mini-tiller and regulated.
As seen, arm-rest frame of the present utility model is by simple lifting structure, realized that namely the arm-rest frame height fast, regulate easily.These handrail pole 2 rotating angles of relative armrest seat 1 are large, and the operating personnel of different heights adjustable arm frame arrive its comfortable height.
Further, described lifting lock shaft 4 begins ascending A, B, the three grades of ladders of C of being provided with successively of diameter from the end of thread, and overlapping respectively on ladder A and ladder B has pair of end fluted disc 3, and namely overlapping altogether on lifting lock shaft 4 has 4 end-toothed discs 3.Lifting lock shaft 4 adopts the design of three grades of ladders, and ladder A and ladder B play position-limiting action to the end-toothed disc 3 of engagement on it jointly with its next ladder respectively, can prevent effectively that the slip between non-end of engagement fluted disc 3 from disturbing.The setting of 4 end-toothed discs 3 also makes armrest seat 1 be connected with handrail pole 2 more firm, locks more firm.
Described lifting lock shaft 4 is fixed with lifting handle 5 away from an end of screw thread, is convenient to the rotation of lifting lock shaft 4.
As shown in figures 1 and 3, armrest frame of mini-tiller of the present utility model, be used on armrest seat 1 and mini-size tillage machine also can corresponding being provided with on the holder of fixed armrest frame vertical axes axial and intermeshing upper end-toothed disc 6 and lower end-toothed disc 7; Armrest seat 1 and holder are adjustable fixing by the steering lock mandrel 8 that runs through upper end-toothed disc 6 and lower end-toothed disc 7; Described steering lock mandrel 8 is threaded with holder.Turn loose steering lock mandrel 8, rock armrest seat 1 to required angle, then turn tight steering lock mandrel 8, by simple steering structure, namely realized fast, easily the left rotation and right rotation of armrest seat 1, effectively enlarged the operative radius of arm-rest frame.Simultaneously, steering lock mandrel 8 also plays armrest seat 1 is connected to effect on the mini-size tillage machine holder.
Described steering lock mandrel 8 is fixed with steering handle 9 away from an end of screw thread, is convenient to the rotation of steering lock mandrel 8.
Further, the top of described upper end-toothed disc 6 is provided with the sleeve 10 that is placed on steering lock mandrel 8.Sleeve 10 can be fixed on end-toothed disc 6.10 pairs of steering lock mandrels 8 of sleeve have positioning action, can weaken rocking between armrest seat 1 and holder.
Armrest frame of mini-tiller of the present utility model adopts above-mentioned technical scheme, by simple structure, has realized fast, easily that namely the height of arm-rest frame is regulated and left rotation and right rotation, and operation is light, simple, and the operating personnel that are fit to different heights use.
