The model utility content
The purpose of this utility model is, at above-mentioned deficiency, provides a kind of simple in structure, the long commentaries on classics power flexible rod of the accurate controlling rod of easy to use and energy.
For achieving the above object, technological scheme provided by the utility model is:
A kind of commentaries on classics power flexible rod, it comprises that a body of rod and is movably set in the bar cover on this body of rod, and it also comprises a rotating machinery, and this rotating machinery is arranged on described bar and puts, and can control that the described body of rod stretches out or this bar cover of withdrawing.
Described bar cover comprises a protecgulum and a bonnet that is connected with this protecgulum, the front end of this bonnet is provided with claw, tail end is provided with assembly department, and the tail end of described protecgulum is provided with and the suitable draw-in groove of described claw, and front end is provided with and the suitable opening of the appearance profile of the described body of rod.Overall structure is simple, makes simple and easyly, effectively reduces cost.Be provided with assembly department, be beneficial to other assembly and assemble mutually, design ingeniously, be beneficial to installation and removal.
Described rotating machinery comprises a rotating shaft, this rotating shaft one end is provided with a live axle, the other end is provided with for the flexible holding cavity of the described body of rod, be provided with internal thread in this holding cavity along its axially-aligned, and be provided with the outside thread suitable with this internal thread corresponding to the described body of rod, at least be provided with one on the described body of rod along its axially extended guide slot, and be provided with the guiding projection suitable with this guide slot corresponding to described opening.Match with guide slot by guiding projection, can effectively prevent the body of rod because of stressedly rotate, bad phenomenon such as displacement, be beneficial to use.
The quantity of described guide slot is four, and it is the center of circle and is symmetricly set on the described body of rod.Make the cross section of the body of rod be one " ten " font structure, reasonable in design, structural strength is big, and stability is high, increases the service life greatly.
Described live axle stretches out from described bonnet, and is provided with a driving gear.Be convenient to be connected convenient the adjusting with other assembly.
The beneficial effects of the utility model are: the utility model structural design is ingenious, rotating machinery adopts the worm structure design, frictional force is big, stability is high, stop to occur skidding, and be drive the body of rod and manifest and stretch out accordingly or the action of withdrawing, can regulate length of telescopic bar arbitrarily, accurately by rotating forward or backwards, easy to use, applied range; Overall structure is simple, rationally in addition, and long service life is made simple and easyly, and cost is low, is beneficial to extensive popularization, is specially adapted to the toy technique field, as is applied in toy excavator, bulldozer etc.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
