Description

Portable rapid telescopic supporting post
Technical field
The present invention relates to a kind of supporting apparatus of mechanical field, particularly a kind of portable rapid telescopic supporting post.
Background technology
Existing suspension device, hydraulic pressure or the pneumatic pillars of adopting as the power source that supports more, suspension device support degree although it is so is big, but because its power fluid potential source or source of the gas weight are big, carry inconvenience, and need use a lot of auxiliary equipment when using it to support, use is loaded down with trivial details, operation inconvenience has a strong impact on rescue time under the emergency relief situation.
Summary of the invention
The present invention be directed to defectives such as existing suspension device structure is loaded down with trivial details, need power source, provide a kind of simple in structure, swift to operate, the portable rapid telescopic supporting post that need not power source easy to carry.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of portable rapid telescopic supporting post, comprise the support post body, described support post body comprises the interconnective extension sleeve of more piece, wherein:
The first segment cover tube bottom on a, described support post body top is connected with a nut, is sleeved on the affixed bottom of the second joint cover tube bottom of first segment sleeve outside, is connected with the screw rod that is connected with nut on this bottom;
B, described support post body bottom the bottom of respectively saving sleeve be equipped with the bottom in band bottom hole, and respectively save sleeve inner and be equipped with the support diving board, this initiating terminal that supports diving board all is connected with the inwall of this section sleeve;
The bottom of c, bottom is connected with next and saves the corresponding alignment pin in bottom hole on the sleeve bottom;
D, respectively save sleeve upper end internal sleeve the fairlead that is connected with a last joint sleeve is housed.
Compared with prior art, the present invention is simple in structure, and load-bearing is big, regulates highly fast, and height adjustment range is big, does not need auxiliary power source, and own wt is light, and is easy to carry, is fit to large batch of systematization production.

Fig. 2 is a sleeve syndeton schematic diagram of the present invention.
Fig. 3 is that the A-A of Fig. 2 is to view.
Fig. 4 is that the B-B of Fig. 2 is to view.
Fig. 5 is a structural representation after the sleeve indentation.
The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Referring to accompanying drawing 1-5, in the present embodiment, this portable rapid telescopic supporting post, comprise the support post body, support post body among the present invention comprises the interconnective extension sleeve of more piece, in the present embodiment, comprise first sleeve 1, second sleeve 2, the 3rd sleeve 6, quadruplet tube 7, the 5th sleeve 9, wherein:
The bottom of first sleeve 1 on support post body top is connected with a nut 3, be sleeved on the affixed bottom 5 in bottom of second sleeve 2 of first sleeve, 1 outside, be connected with the leading screw 4 that is connected with nut 3 on this bottom 5, this leading screw 4 passes the screwed hole at nut 3 centers, spins with nut 3.
Support post body bottom respectively save sleeve, promptly the bottom of the 3rd sleeve 6, quadruplet tube 7, the 5th sleeve 9 is equipped with the bottom 14 in band bottom hole 13, and respectively save sleeve inner and be provided with support diving board 12, this initiating terminal that supports diving board 12 is all fixedlyed connected with the inwall of this section sleeve.
The bottom of the bottom of second sleeve 2, the 3rd sleeve 6, quadruplet tube 7 all is connected with next and saves bottom hole 13 corresponding alignment pins 11 on the bottom 10 that overlaps tube bottom.Because the 5th sleeve 9 is the lowermost end sleeve, so do not have alignment pin 11 on the bottom 14 of this sleeve.
Each saves sleeve upper end internal sleeve the fairlead 8 that is connected with a last joint sleeve is housed, and this fairlead 8 is arranged between the two neighbouring joint sleeves, is fixed in down the top of joint sleeve, last joint sleeve is played the effect of stabilising direction.
Supporting diving board 12 is the drum structure that stretches along the hand of spiral.Alignment pin 11 is arranged on the inboard of the support diving board 12 in next joint sleeve on the last joint sleeve bottom, when supporting diving board 12 inboards and being subjected to the support force of alignment pin 11 near its place sleeve lining, and when supporting diving board 12 and not being subjected to the support force of alignment pin 11, owing to itself have elastic buckling power, supporting diving board 12 can curl and structure in the form of a roll along the hand of spiral, its drum diameter is slightly less than the diameter of a joint sleeve bottom, and a last joint sleeve is played a supporting role.
Can be during minimum support with in the whole indentation outermost of the more piece sleeve sleeve, can rapidly inner sleeve be pulled out when supporting higher weight, diving board can prop up the sleeve of pulling out automatically, go up most a joint and be the feed screw nut type, can reconcile the arbitrary height in the joint, generally be applicable to the trace adjusting, the present invention can make series height and joint number.
Below according to structural representation explanation using method: as Fig. 1 is the state that whole support column is all pulled out, when being drawn out on the bottom 10 alignment pin 11 that connects and surpassing the height that supports diving board 12 as quadruplet tube 7, support diving board 12 and lose support force, be curled into the cylindric joint bottom that props up of Fig. 3, Fig. 4, the initiating terminal that supports diving board 12 is connected with sleeve 9 inwalls, be curled into than the smaller wound packages of a last joint bottom diameter, will go up a joint and prop up; Clockwise rotate a joint sleeve during indentation, as clockwise rotate quadruplet tube 7, alignment pin 11 on the bottom 10 promotes to support diving board 12 along the circumference hand of spiral and abuts on the inwall of the 5th sleeve 9, after rotating a circle, four alignment pins 11 on quadruplet tube 7 bottoms, when supporting on the inwall that diving board 12 all abuts in the 5th sleeve 9, as Fig. 5, quadruplet tube 7 can fall back in the 5th sleeve 9, adjust the position four alignment pins 11 on the bottom 10 are all dropped in four holes on the bottom 14 of the 5th cover tube bottom, as Fig. 5, this moment, the quadruplet tube 7 just all fell back in the 5th sleeve, bottom 10 is close to bottom 14, guarantees support strength.The syndeton and the using method of the 4th joint, the 3rd joint, the second joint sleeve are identical.And employing feed screw nut form between first sleeve 1 and second sleeve 2, screw mandrel 4 is fixedlyed connected with the second sleeve bottom 5, nut 3 is connected with first sleeve, rotates the height that first sleeve 1 can be adjusted first sleeve, is beneficial to adjust the arbitrary height between joint and the joint.
