Description

A kind of scissor-like jack with quick change top structure
Technical field
The present invention relates to a kind of lifting gears of removable load-supporting part, specifically a kind of to have quick change top structure Scissor-like jack.
Background technique
A large amount of family-sized car or urban off-road vehicle or small-sized pickup, which are provided with, acts the scissor-like jack reused with vehicle, It is widely applied and is facilitated to the suitability demand of specific vehicle the diversity of scissor-like jack pattern.It is standby as automobile With the professional production quotient of tool, various vehicles are obtained by jacking portion in long-term design, the practice of each link of producing and selling Position entity structure pattern, thus also forms the scissor-like jack with various styles top structure, that is to say, that for being matched Cover vehicle by the different every technical characteristic and special requirement in jacking position, manufacturer can will be with the matched scissor-like jack of vehicle Component is come directly towards from rational mechanics, the angle Method of Spreading Design of the mechanics of materials, production service, especially protrudes such jack load-supporting part Use reliability and safety.These tops with various application characteristics and matching are in general in same specified carrying On the scissor-like jack of amount, often its two pivot hole center for coming directly towards component is away from two pivots coupled with the implementation rotation of jack ontology Center between axis is similar away from material used in identical, two pivots, and all makes the shaft shoulder at the both ends of pivot, joins in being permanently fixed It connects, in this way, the top component list of every kind of specific structure just can only be thin after having matched the jack ontology with common structural feature Point in various specific vehicles, in short, this scissor-like jack with identical jack ontology be difficult to realize produce, Sale or even the versatility in client is specifically used are exchanged, for this purpose, designer proposes on jack ontology with simplicity Feasible method exchanges the new approaches theory of top component, from the reasonable arrangement for being conducive to production technology and reduces operating cost, Sale, carrying cost are advantageously reduced, the top that client selects each money adaptation vehicle using the combination of same jack ontology is conducive to The angle of head part studies the Quick Release and fast-assembling between various tops and same jack ontology.
Summary of the invention
Task of the invention lies in the deficiency for above-mentioned background technique and correlation technique scheme, designers think scissors Jack comes directly towards in two pivot holes of component in jacking vehicle and has been primarily subjected to the support reaction from two pivots, and is removing When moving the jack, often having user to compare smoothly, directly holding top component proposes scissor-like jack entirety, exists in this way In handling process, the requirement to top component can necessarily be such that it is bound up on properly on the ontology of jack always, certainly, The effect of lateral force can be all generated when lifting vehicle, equally when coming directly towards component by turning torque effect, ought to also ensure to push up It is coupled jack ontology to head part all-the-time stable, then, the reliability of continuation of insurance barrier traditional structure is relayed in new solution Just become the important content of this case technology change with exchange of the multifarious top component on jack ontology is realized.
Above-mentioned purpose of the invention is achieved through the following technical solutions: a kind of scissors thousand with quick change top structure Jin top, including pedestal lower branch arm assembly, screw rod power part, top component and upper branch arm assembly, it is characterized in that: upper branch arm In assembly, the second teeth portion that support arm connects firmly in upper left the first teeth portion, third teeth portion are connected firmly with upper right support arm respectively, the 4th tooth Portion's engagement;The left pivot hole of the third in the support arm of upper left, the first left pivot hole on U-shaped hog frame, are successively passed through with left pivot The 4th left pivot hole in two left pivot holes and upper left support arm;The third right pivot in upper right support arm is successively passed through with right pivot The first Right, the second Right on hole, U-shaped hog frame and the 4th Right in upper right support arm, and with locking Screw external screw thread and the threaded hole of right pivot end form screw thread pair;The left pivot of formation is machined in left pivot small end Two shaft shoulders and axial limiting of the left pivot of left first shaft shoulder of pivot common implementing in upper branch arm assembly;In right pivot outside cylinder On to be machined the axial limiting lug formed combine with the right pivot shaft shoulder axis of the implementation right pivot in upper branch arm assembly To limit;It is equipped with the first oblique cutting slot of top on two side plate bodies on the component of top and the second oblique cutting slot of top corresponds respectively to a left side Pin circle column implements clearance fit, and the top arc-shaped slot being equipped with and top Thuban shaft through-hole correspond respectively to right pivot outer circle Column implements clearance fit.
Wherein, the outer end face that axially-displaceable momentum of the right pivot on upper branch arm assembly meets threaded hole being capable of the retraction right side 4th Right of upper branch arm entity, while meeting top arc-shaped slot and being rotatably inserted into right pivot outside cylinder implementation gap Cooperation.
Wherein, asymmetrical frame top technology groove is offered in the top end part position of U-shaped hog frame.
Wherein, axially-displaceable momentum of the left pin circle column in upper branch arm assembly meets the first oblique cutting slot of top, top The conformability of first second oblique cutting slot is inserted into.
Wherein, the nominal radius of the center cambered surface of arc-shaped slot is come directly towards equal to the right pivot and left pivot in upper branch arm assembly The axis center of axis away from.
Compared with the prior art, the invention has the beneficial effects that: by the way that traditional upper branch arm component is decomposed into upper branch Arm assembly and top component simultaneously form each geometric element of quick convenient disassembly and assembly structure, greatly facilitate identical upper branch arm combination Body is assembled different style tops component by permutation and combination respectively, is reduced manufacturing process cost, is also substantially improved automobile factory and given birth to Free assembling of the various different automobile types that production and marketing is sold to top component, so it facilitates terminal user and chooses a variety of style tops portion After part using same jack ontology carry out applicability replacement top it is preferable to use.
