Abstract

The utility model relates to an improved flagpole device which is characterized in that a flagpole is formed by invaginating a plurality of pipes. The upper pipes and the lower pipes can be telescopic. When flag pipes upwards extends to reach a destining length, shims of the flag pipes can butt on rolled edges of the flag pipe of a lower layer, then, fixing nails are inserted, and the flagpole can be fixed. The fixing nails are pulled out, and the flagpole can be also downwards shrunk section by section. A pulley is sheathed on a fixing hook of the flagpole, and the pulley can be freely disconnected and can be also fixed by a lock. The utility model has the advantages that the sections of the flagpole are invaginated together, and the installation is simple, convenient and labor-saving. For the phenomena that the pulley is damaged, a rope is twisted and broken by pulling, etc., generally, one person can easily repair and restore on the ground.

Description

The flexible free pulley flagpole of holding concurrently of multitube

The utility model is a kind of device that improves the flagpole structure.

Known to the applicant, existing flagpole, its structure is a single tube, not flexible, pulley is fixing extremely on flagpole.Under this state of the art, must bring such drawback: must many people make a concerted effort to install, when useless, useless power; Run into pulley and damage, rope breaks, twist when phenomenon such as stumbling, and the flagpole of will separating usually, fall can keep in repair, restore, very trouble.

And task to be solved in the utility model will provide a kind of multitube the flexible free pulley flagpole of holding concurrently exactly, and this flagpole can stretch up and down, and free wheel can freely load and unload, with handled easily, maintenance.

The purpose of this utility model is achieved in that flagpole is made up of many pipeline section intussusceptions, pipeline section divides low section pipe, stage casing pipe, top section pipe, wherein the stage casing pipe has multistage (being advisable with 3～4 sections), the pipeline section diameter of low one deck is successively greater than last layer pipeline section diameter (being advisable greater than 6～7 millimeters), make and respectively manage layer overlaps, again retractable.End section pipe, pipe upper end, stage casing be crimping inwardly; Stage casing pipe, section pipe two outsides, lower end, top are pasted with pad (pad is arc), be equipped with screw, stretch on piecemeal when flagpole like this, to predetermined altitude, pad will withstand on the crimping, and flagpole is stretched on no longer, in screw, insert solid nail then, flagpole will be fixed and contract under unlikely, unplugs solid nail when needing, and flagpole can be withdrawn again piecemeal.Be equipped with admittedly on top section pipe, the end section pipe and collude, pulley sleeve is colluding admittedly, can separate easily, and also lockable is fixed.

Such flagpole because segmentation is together nestable, is installed very easy to be laborsavingly, runs into that pulley damages, rope twists to stumble and common phenomenon such as break, and generally need only a people can easily keep in repair, restore on ground.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the audio-visual picture under the full situation that contracts down of the utility model; Fig. 2 is that the utility model is at the last sectional drawing of stretching under the situation; Fig. 3 is an end section pipe; Fig. 4 is the stage casing pipe; Fig. 5 is top section pipe; Fig. 6 is a pad; Fig. 7 is solid nail; Fig. 8 is for colluding admittedly; Fig. 9 is free pulley.

Wherein: 1. crimping, 2. drain hole, 3. screw, 4. recess in the flag section, 5. pad evagination place, 6. hook part admittedly, 7. pulley trepanning, 8. top section pipe, 9. stage casing pipe, 10. end section pipe, the free pulley of , the pad, follows closely admittedly.

As shown in Figure 1 and Figure 2, the utility model is formed by many pipeline section intussusceptions.Pipeline section divides end section pipe (Fig. 3,10.), stage casing pipe (Fig. 4,9.), top section pipe (Fig. 5,8.) again.Wherein the section pipe is positioned at the flagpole bottom at the end, and a top section pipe is positioned at flagpole top, and mid portion is the stage casing pipe.End section pipe, the inside crimping in pipe top, stage casing are 1..Stage casing pipe, section pipe both sides, bottom, top respectively have successively a screw 3., an interior recess 4., pad (Fig. 6, ) is arc, on an evagination place is arranged 5., 5. 4. interior recess just coincide with the evagination place.Like this, top section pipe 8., 9. the stage casing manage that the both sides, bottom just can respectively be pasted with a pad.When top section pipe 8., the stage casing pipe reaches predetermined altitude on 9., pad will withstand on crimping and 1. go up, and inserts solid nail [Fig. 7, ] at screw on 3. again, flagpole can not be fixed any more to contract.Unplug solid nail , flagpole can bounce back again piecemeal.End section pipe 10., 8. top section pipe go up and respectively be equipped with one and collude (Fig. 8) admittedly, 7. free pulley [Fig. 9, ] is provided with trepanning, and 6. it be enclosed within the hook part of colluding admittedly, just can actual operation, also can freely separate.Certainly 6. the free pulley that 10. goes up for end section pipe can also be locked in admittedly the hook part to it.2. the lower end has drain hole to end section pipe [Fig. 3,10.], in case ponding.

Claims

1, the flexible free pulley flagpole of holding concurrently of multitube, it is characterized in that: flagpole is made up of the multitube intussusception that can stretch, and top section pipe, pipe lower end, stage casing are equipped with free pulley with pad on top section pipe, the end section pipe.

2, flagpole according to claim 1 is characterized in that: pad is arc, its evagination place just kiss with the interior recess on top section pipe, the stage casing pipe and, therefore can be attached on the flag pipe.

3, flagpole according to claim 1, it is characterized in that: pulley has trepanning, can be enclosed within consolidating of flagpole and collude, and lockable is locked in and colludes the place admittedly.
