In the figure: 1. a telescoping device; 2. rotating the handle; 3. a length adjustment rod; 4. a fulcrum point.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, in this embodiment: the novel deformation-preventing support arm comprises a telescopic device 1, a rotating handle 2, a length adjusting rod 3 and a fulcrum 4, wherein the telescopic device 1 is a cylindrical internal thread sleeve, threaded rods are respectively inserted into two ends of the telescopic device 1, the rotating directions of the threads of the two threaded rods are opposite, and a bolt hole is formed in one end of each threaded rod, which is far away from the sleeve; the support arm can support base materials such as large steel pipes or I-shaped steel, construction time is saved, personnel investment is reduced, the support arm can be flexibly used and is convenient to operate, and construction quality and working efficiency of a jacket, a ship leaning piece or I-shaped steel are improved.

In the embodiment, the whole rotary handle 2 is of a concave structure, a connecting rod in the middle of the rotary handle 2 penetrates through the middle of a sleeve of the telescopic device 1, and two ends of the connecting rod in the middle of the rotary handle 2 are respectively and vertically welded with a short upright post; the rotating handle 2 is a concave structure as a whole, and a middle connecting rod vertically penetrates through the middle of a sleeve of the telescopic device 1 and can move transversely. The length adjusting rod 3 is a steel pipe with a bolt hole at one end and a pipe sleeve at the other end, and a bolt is arranged in the middle of the side wall of the pipe sleeve on the length adjusting rod 3; a steel tube or threaded rod may be inserted into the tube housing and a bolt of the tube housing can be screwed into a bolt hole of the steel tube or threaded rod. The fulcrum 4 is an arc-shaped steel plate or a plane steel plate, a fixed pipe sleeve is welded in the middle of the bottom of the fulcrum 4, and a bolt is vertically arranged in the middle of the pipe sleeve; reasonable structure and convenient use.

The utility model discloses a theory of operation and use flow: first step, adjust twist grip 2 and make novel type support arm of preapring for an unfavorable turn of events stretch out and draw back to the shortest. And secondly, increasing or reducing the length adjusting rod 3 according to the field requirement, so that the novel deformation-preventing support arm reaches a proper length. In a third step, a suitably shaped fulcrum 4 is mounted on the telescopic device 1 or the length adjustment lever 3. And fourthly, placing the novel deformation-preventing support arm in a position needing to be supported, and adjusting the rotating handle 2 to enable the novel deformation-preventing support arm to be tightly attached to the base material needing to be supported. And fifthly, after the construction is finished, operating the steps in a reverse order.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
