The retractable support rod for supporting the heavy object is characterized in that the combined support rod is formed by sleeving an outer rod (10), an inner rod (8) and an intermediate rod (9) positioned between the outer rod (10) and the intermediate rod (9); the stressing support rod comprises a rocking handle (3), a lead screw (2) and a lead screw nut (4), a push rod (6) and an external erected pipe (5), wherein the shaft end of the rocking handle and the bottom end of the lead screw (2) are respectively provided with bevel gears which are matched, the push rod (6) is sleeved at the outer side of the lead screw (2) and attached to the upper side of the lead screw nut (4), the top of the push rod (6) is provided with a connection seat (14), the connection seat (14) is provided with a connection hole, and the connection hole is connected with at least one positioning hole of the intermediate rod (9) through a connection pin (12). The utility model has the advantages of convenience for use, large height regulating range and firm support.

Description

The manual support bar

Technical field

The utility model belongs to a kind of mechanical device, particularly relates to a kind of retractable supports bar that is used to support weight.

Background technology

In occasions such as rescue and constructions works, need build some interim bracing or strutting arrangements sometimes, to construct working space or to implement security protection, for carrying out the follow-up work preparatory condition.Because the complicated condition of operation field, abominable; And the urgency of time, require above-mentioned bracing or strutting arrangement easy to carry and transport, the process of building and dismantling is fast fast; Support distances is adjustable flexibly; And adjustable effective scope of application is the bigger the better, and, all must be solid and reliable in the support of arbitrary position.Scaffold that just generally uses at present and jack etc., the process of perhaps building and dismantling is loaded down with trivial details, and holding time is long, and perhaps spendable altitude range is extremely limited, all can not reach above-mentioned requirement well.

The utility model content

The purpose of the utility model just provides a kind of novel manual support bar, is easy to carry, builds and dismantle to reach, and the support distances adjustable range is big, the reliable purpose of firm supporting.

Manual support bar disclosed in the utility model is made up of base, combination strut and afterburning strut, it is characterized in that described combination strut is to be formed by outer bar, interior bar and intermediate bar suit between the two, and the bottom of outer bar and base connect; On above-mentioned outer bar, interior bar and the intermediate bar locating hole is arranged, cooperate, realize that the connection behind the combination strut suit is located with alignment pin; Described afterburning strut is made up of rocking handle, the leading screw that cooperatively interacts and feed screw nut, push rod, outrigger pipe; Rocking handle axle head and leading screw bottom have bevel gear to match respectively; Pushing rod sleeve is loaded on the leading screw outside, abuts in the feed screw nut upside; The outrigger pipe is positioned at the outside of push rod, and both are slidingly matched; There is connecting pore at the push rod top for connecting seat on it, through at least one locating hole connection of coupling pin and above-mentioned intermediate bar.

Manual support bar disclosed in the utility model during use, is at first regulated the pattern length of intermediate bar and interior bar according to the roughly situation of support distances; Utilize the alignment pin location; Select the connection seat at suitable locating hole and push rod top to connect then, shake rocking handle then, by the effect of push rod; Drive intermediate bar and further raise, with weight bracketing to required final height.The utlity model has good effect easy to use, that height adjustment range big, support is firm.

Description of drawings

Accompanying drawing partly discloses the specific embodiment of the utility model, wherein:

Fig. 1 is the utility model elevation;

Fig. 2 is that A-A is to view.

The specific embodiment

Like Fig. 1～shown in Figure 2, manual support bar disclosed in the utility model is made up of base 1, combination strut and afterburning strut.Described combination strut is to be formed by outer bar 10, interior bar 8 and intermediate bar 9 suits between the two.On above-mentioned outer bar, interior bar and the intermediate bar locating hole 11 is arranged, cooperate with alignment pin 13.According to the length that the roughly situation of support distances is regulated the combination strut, then alignment pin is inserted in the locating hole, realize connecting the location.For reaching the firm effect of bracketing, there is carriage 7 on the top of interior bar, can connect airtight with weights and touch.

Described afterburning strut is made up of with feed screw nut 4, push rod 6, outrigger pipe 5 rocking handle 3, the leading screw that cooperatively interacts 2.Rocking handle axle head and leading screw bottom have bevel gear to match respectively.Pushing rod sleeve is loaded on the leading screw outside, abuts in the feed screw nut upside.The outrigger pipe is positioned at the outside of push rod, and both are slidingly matched.There is connecting pore at the push rod top for connecting seat 14 on it, connect through coupling pin 12 at least one locating hole with above-mentioned intermediate bar.

Above-mentioned outer bar, interior bar and intermediate bar can be square tubes, also can be pipes, wherein are best with the square tube.According to the needs of bracketing distance, the intermediate bar between outer tube and the interior pipe can be one, also can be some, connects combination through locating hole and alignment pin and gets final product.

Claims
