Abstract
The utility model relates to a suspension rod device, which comprises a sleeve head, a sleeve and a telescopic sleeve, wherein the sleeve head is connected to the sleeve through a first buckle at the end, a plurality of clamping holes are formed in the sleeve along the length direction of the sleeve, the clamping holes are arranged in pairs in the diameter direction of the sleeve, second buckles, which are fixedly connected to the end of the telescopic sleeve, are clamped in the clamping holes, and the other end of the telescopic sleeve is fixedly connected to a handle. The suspension rod device has a simple structure, the telescopic sleeve is telescopic in the sleeve, so that the length of the device is shortened or lengthened, a ladder or a foot stool is replaced, the safety is improved, and meanwhile, the sleeve head can be replaced, so that the working efficiency is improved.
Description
Technical field
The utility model belongs to aid technical field in air-conditioning installation process, relates to a kind of derrick rig.
Background technology
In air-conditioning installation process, in upper hanger, all also with ladder and foot rest, on personnel, go down to exist like this potential safety hazard; Meanwhile, now used is pullover single cannot replacing, and connecting rod used is can not regulating according to the height of floor of fixing, therefore inefficiency.
Summary of the invention
The utility model provides a kind of safety, efficient derrick rig for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of derrick rig, comprise pullover, sleeve pipe and telescopic tube, described pullover the first buckle by end is connected with sleeve pipe, on described sleeve pipe, be provided with some hole clippings along casing length direction, described hole clipping arranges in pairs in the diametric(al) of sleeve pipe, in described hole clipping, snap in the second buckle that is fixedly connected on telescopic tube end, the other end of described telescopic tube is fixedly connected with jug.
Described the second buckle is identical with the structure of the first buckle, be all respectively by spring be connected to telescopic tube and pullover on.
Advantage and the good effect that the utlity model has are: the utility model is simple in structure, at cover inner telescoping tube, can make the length of this device shorten or elongated by telescopic tube, ladder or foot rest are replaced, improve security, simultaneously pullover replaceable, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model mounting structure schematic diagram;
In Fig. 1,1. pullover, 2. the first buckle, 3. sleeve pipe, 4. hole clipping, 5. telescopic tube, 6. handle, 8, the second buckles.
The specific embodiment:
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of derrick rig, comprise pullover 1, sleeve pipe 3 and telescopic tube 5, pullover 1 is connected with sleeve pipe 3 by the first buckle 2 of end, on sleeve pipe 3, be provided with some hole clippings 4 along sleeve pipe 3 length directions, hole clipping 4 arranges in pairs in the diametric(al) of sleeve pipe 3, snaps in the second buckle 7 that is fixedly connected on telescopic tube 5 ends in hole clipping 4, and the other end of telescopic tube 5 is fixedly connected with jug 6.The second buckle 7 is identical with the structure of the first buckle 2, is to be all connected on telescopic tube 5 and pullover 1 by spring respectively.
When use, the first buckle 2 on pullover 1 is snapped in the hole of sleeve pipe 3, and then the second buckle 7 of telescopic tube 5 ends is snapped in the hole clipping 4 of sleeve pipe 3, suspension rod expand tube passes from No. 1 pullover centre, the holding screw of expand tube is just in time stuck in pullover wheel like this, operating personnel, as long as sleeve pipe 1 is lifted and expand tube is aimed to the hole of accomplishing fluently in advance installs, just can carry out fastening bolt by handle 6.
Pullover 1 can select wheel spanner, can also change pullover 1 according to the size of expand tube simultaneously.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and those of ordinary skill in the field should be appreciated that still and can modify or part technical characterictic is equal to replacement the specific embodiment of utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technology of the utility model request protection.
