Abstract

The invention provides a roll up supporting rod and an assembling method thereof. The roll up supporting rod comprises a fat tube, a thin tube, a connecting rope, fixed rings and hooks, wherein the fixed rings and the hooks are manufactured by winding metal wires. The thin tube is sleeved with the fat tube. The hooks bend towards the directions of the fixed rings and are on the same axis with the fixed rings. During assembling, the connecting rope is tied to one fixed ring, and the fixed ring is pushed from one end of a lower thin tube until the corresponding hook is located in a lower fat tube; after the connecting rope is penetrated through a center fat tube, the tail end of the connecting rope is tied to the other fixed ring, the fixed ring is pushed from one end of an upper thin tube until the corresponding hook is in an upper fat tube located at the tail end, of the corresponding hook, and assembling is completed. According to the roll up supporting rod, the hooks are elastic and can stretch out and draw back flexibly in the thin tube, so that the hooks can be fixed in the fat tube conveniently, and the fixed rings and the hooks can be taken out conveniently; the roll up supporting rod is small in structure and high in practicability.

Description

A kind of post stand strut and assembling method thereof

Technical field

The present invention relates to post stand and make field, be specifically related to a kind of post stand strut and assembling method thereof.

Background technique

For the ease of storage, post stand strut is set to the multistage of movable connection more, and the multistage body of rod is internally connected with bridle line, is convenient to preserve after being convenient to the dismounting of multistage strut.As described in Figure 1, what use in prior art is an annular ring, by bridle line tying-up on the annular rings, with longer hook, bridle line is drawn in extra heavy pipe inside from longer extra heavy pipe one end, until annular ring is fixed on the capillary tips in extra heavy pipe, troublesome poeration, and also more difficult when annular ring is pulled out from extra heavy pipe.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of post stand strut, comprise extra heavy pipe, tubule, bridle line, one coiling and shaping retainer ring and hook, described extra heavy pipe comprises extra heavy pipe, middle extra heavy pipe, lower extra heavy pipe, described tubule comprise tubule, lower tubule, described upper extra heavy pipe is set on described upper tubule, described lower extra heavy pipe is set on described lower tubule, and described hook is bending towards described retainer ring direction, and described hook and described retainer ring are on the same axis.

Further, described retainer ring and described hook are formed by Spring Steel Wire coiling, make hook elastic strain can occur, and compressed with by tubule, open to be fixed in extra heavy pipe in extra heavy pipe time in tubule.

Further, the width of described hook increases to the one end near described retainer ring gradually from the one end away from described retainer ring.

Further, the Extreme breadth of described hook is greater than the diameter of described thin tube inner wall, to ensure that hook is pushed to after in extra heavy pipe, freely can not eject from tubule.

Further, the external diameter of described tubule equals the inner diameter of described extra heavy pipe.

Further, the length of described tubule is the 1/4-1/3 of the length of described extra heavy pipe.

Further, the 1/5-1/2 of the length of described tubule is positioned at described extra heavy pipe outer end, and the tubule being positioned at extra heavy pipe outer end is socketed in another extra heavy pipe, to connect into longer strut.

When assembling this post stand strut, need following operating procedure:

(1) by bridle line tying-up on described retainer ring, described hook is front, and described retainer ring, rear, promote described retainer ring to described hook and is arranged in lower extra heavy pipe and is positioned on the end wall of described lower tubule from described lower tubule one end;

(2) described bridle line is passed middle extra heavy pipe;

(3) by end tying-up retainer ring described in another of described bridle line, described hook is front, described retainer ring, rear, promote described retainer ring to described hook from described upper tubule one end and is arranged in the described upper extra heavy pipe of end and is positioned on the end wall of described upper tubule.

The advantage that the present invention has and good effect are:

Hook in post stand strut of the present invention has elasticity, in compressive state in tubule, open-shaped state in extra heavy pipe, this character is utilized to advance extra heavy pipe from shorter tubule end easily and to be fixed in extra heavy pipe, also convenient will hook from tubule one end pulls out with retainer ring, solve in prior art and need, with longer hook, bridle line is drawn in extra heavy pipe inside from longer extra heavy pipe one end, until annular ring is fixed on the capillary tips in extra heavy pipe, troublesome poeration, problem also more difficult when annular ring is pulled out from extra heavy pipe.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, the invention provides a kind of post stand strut, comprise extra heavy pipe 1, tubule 2, bridle line 5, one coiling and shaping retainer ring 3 and hook 4, described extra heavy pipe 1 comprises extra heavy pipe 13, middle extra heavy pipe 12, lower extra heavy pipe 11, described tubule 3 comprise tubule 22, lower tubule 21, described upper extra heavy pipe 13 is set on described upper tubule 22, described lower extra heavy pipe 11 is set on described lower tubule 21, described hook 4 is bending towards described retainer ring 3 direction, and described hook 4 and described retainer ring 3 are on the same axis.

Further, described retainer ring 3 and described hook 4 are formed by Spring Steel Wire coiling, make hook 4 elastic strain can occur, and compressed with by tubule 2, open to be fixed in extra heavy pipe 1 in extra heavy pipe 1 time in tubule 2.

Further, the width of described hook 4 increases to the one end near described retainer ring 3 gradually from the one end away from described retainer ring 3.

Further, the Extreme breadth of described hook 4 is greater than the diameter of described tubule 2 inwall, to ensure that hook is pushed to after in extra heavy pipe 1, freely can not eject from tubule 2.

Further, the external diameter of described tubule 2 equals the inner diameter of described extra heavy pipe 1.

Further, the length of described tubule 2 is the 1/4-1/3 of the length of described extra heavy pipe 1.

Further, the 1/5-1/2 of described tubule 3 length is positioned at described extra heavy pipe 1 outer end, and the tubule 2 being positioned at extra heavy pipe 1 outer end is socketed in another extra heavy pipe 1, to connect into longer strut.

When assembling this post stand strut, need following operating procedure:

(1) by bridle line 5 tying-up on described retainer ring 3, described hook 4 is front, and described retainer ring 3, rear, promote described retainer ring 3 to described hook 4 from described lower tubule 21 one end and is arranged in lower extra heavy pipe 11 and is positioned on the end wall of described lower tubule 21;

(2) described bridle line 5 is passed middle extra heavy pipe 12;

(3) by end tying-up retainer ring 3 described in another of described bridle line 5, described hook 4 is front, described retainer ring 3, rear, promote retainer ring 3 to described hook 4 from described upper tubule 22 one end and is arranged in the described upper extra heavy pipe 13 of end and is positioned on the end wall of described upper tubule 22.

Also than being easier to during taking-up, because tubule is shorter, can put in tubule 2 with general clip, and the flared end clamping hook 4 makes the mouth that opens linked up with compress thus take out retainer ring 3 and hook 4.

Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
