The design of arc chute 103, plays the position-limiting action to the first slide block 108 on the one hand, is limited in the scope of this arc chute 103 by the whole motion track of the first slide block 108; On the other hand, also serve the supporting role to driving link 105, the stability of the afterburning mechanical arm of whole variable block can be strengthened, make the slip of driving link 105 more level and smooth, steady, make it more convenient and practical.Meanwhile, the setting of arc chute 103 also mitigates the weight of box body, decreases materials.
When rotating driving link 105, rotate centered by the axis of the axis of through hole 102 or perhaps limiting stopper 107, and the motion track of the first slide block 108 is tracks that arc chute 103 limits, therefore the center of circle of this arc chute 103 is also positioned at the center of this through hole 102.
Second slide block 109 slides thus drives bracing wire to pull in straight 104, and the stroke of therefore whole bracing wire is consistent with the length of straight 104, and concrete length can design according to the demand of reality.
Preferably, in the present embodiment, the box body 101 of the afterburning mechanical arm of variable block is triangle, and one jiao near through hole 102 is rounded down 112.Leg-of-mutton box body 101 can receiving opening 102, arc chute 103 and straight 104 preferably, can guarantee the function of each parts, compare again saving material.Due to user, hand is closer to this angle with through hole 102 on box body 101 in use, and user may touch herein in some cases, and the setting of fillet 112 makes comparatively round and smooth herein, can not hurt the hand of user.
The afterburning mechanical arm of the variable block obtained by above-mentioned design, its structure is simple, easy and simple to handle, comparatively laborsaving during use.
Second embodiment, refers to Fig. 7-11
The afterburning mechanical arm of the variable block that the present embodiment provides, its basic structure is identical with the first embodiment with the technique effect of principle and generation, is concise and to the point description, and the not mentioned part of the present embodiment part, can with reference to corresponding contents in the first embodiment.
The afterburning mechanical arm of the variable block obtained by above-mentioned design substantially can be met it and normally use, but in line with improving the aim of its function further, designer has carried out further improvement to the afterburning mechanical arm of this variable block.
In use, control lever 201 is be fixedly connected with limiting stopper 107 to the afterburning mechanical arm of variable block, limiting stopper 107 can be driven to rotate when guaranteeing rotating operation bar 201.Concrete connection mode can select welding, clamping, by other modes such as the engagements of gear.Specifically can determine according to the shape of the connecting bore of control lever 201 coupling end.
Present embodiments provide a kind of structure of concrete limiting stopper 107: on the limiting stopper 107 stretching out described through hole 102, annular is distributed with latch 110.Latch 110 can coordinate with the draw-in groove of the connecting bore inside of control lever 201 coupling end, makes control lever 201 relative with both limiting stoppers 107 fixing.
Preferably, the middle part of stretching out the limiting stopper 107 of described through hole 102 is provided with groove 111.Be provided with elastic bumps in the connecting bore of some control lever 201 coupling end, during installation, first by projection by entering, connecting bore is packed in limiting stopper 107, during to correct position, projection can stick in groove 111, now control lever 201 substantially very firm be connected to limiting stopper 107 together with.
Preferably, described latch 110 has 20-40.The latch 110 of this quantity can match with more control lever 201.
Preferably, the both sides of described box body 101 are provided with the mounting hole 114 that afterburning for this variable block mechanical arm can be installed on the vehicle.Offer the tapped bore mated with this mounting hole 114 on a vehicle, can by firm being fixed on the vehicle of the afterburning mechanical arm of this variable block by bolt and pad.
This box body 101 is divided into the left side and right-hand part that can cooperatively interact, during making, two parts separately make, during assembling, driving link 105 and driven member 106 are put in corresponding through hole 102, arc chute 103 and straight 104, again left side and right-hand part are secured together, the assembling of the afterburning mechanical arm of variable block can be completed.
Left side and right-hand part are fixed together by welding, clamping or screw thread.Guarantee both stable being connected.
Described driven member 106 is provided with the fixed part 113 of the bracing wire can fixing the vehicle.The bracing wire of the vehicle can be fixed on driven member 106 by fixed part 113.Present embodiments provide a kind of fixed part 113 of concrete shape, consult Figure 10, bracing wire, for having the hole of opening, during installation, can be mounted on driven member 106 by this fixed part 113 easily.
Preferably, described box body 101 is made with metal, and described driving link 105 and driven member 106 are made with hard alloy.Metal box body 101 can guarantee the service life that the afterburning mechanical arm of this variable block is longer.And driving link 105 and driven member 106 play afterburning effect, larger pulling force during use, need be born, therefore adopt hard alloy to make.
In the present embodiment, the inwall of the through hole 102 of box body 101, arc chute 103 and straight 104 is through cementation process.By the inside allowing active high carbon atom be diffused into metal, form the cementation zone that certain thickness carbon content is higher, then through quenching tempering, its superficial layer carbon content is improved, and the carbon content of heart portion maintenance original concentration.The effect of cementation process is: the resistance to abrasion improving superficial layer, keeps heart portion to have high shock-resistant ability, i.e. obdurability simultaneously.
More durable by box body 101 1 aspect of cementation process, still keep it tough on the other hand, further increase service life.
The afterburning mechanical arm of the variable block that the present embodiment provides has carried out further restriction by above-mentioned supplementary features to the afterburning mechanical arm entirety of this variable block, the basis of guaranteeing original function turn increases practicality and stability, makes it convenient durable.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
