Abstract

The invention relates to a portable supporting frame, wherein an open clamp is made of plastic by injection molding; a bottom plate of the open clamp forms an included angle with two clamping arms respectively; each included angle is an acute angle; the two clamping arms have the same shape and are in mirror symmetry; the upper ends of the two clamping arms are open and are turned out; the upper parts of the two clamping arms are provided with shrinking shoulders; the bottom plate of the open clamp is provided with a mounting screw hole; under the action of external force, the included angles formed by the two clamping arms and the bottom plate change; and after the external force action loses, the two clamping arms are recovered to the original positions under the elastic action of the material so as to clamp supported equipment. The portable supporting frame has the advantages that the clamping arms can produce large elastic deformation, so that a clamped object is easy to clamp tightly and the outer surface of the clamped object is not damaged, and the portable supporting frame is particularly suitable for clamping pieces of light equipment which have irregular shapes and are difficult to clamp and has a wide application range and practical value.

Description

The Portable support frame

Technical field

The present invention relates to the device support device, particularly a kind of Portable support frame, Applicable scope is extensive, the light equipment that the out-of-shape that is mainly used in being installed is difficult for being installed.

Background technique

Light equipment is when outdoor application, usually need to install or provisional lifting, continuous progress along with technology, the appearance forrns of various product is more and more diversified, and shape of product is specification not, therefore give and install or the provisional equipment of lifting is made troubles, brought no small difficulty, especially aboard ship or the environment such as high-altitude.The provisional equipment of lifting adopts the assembling caliper type supporting frame to finish usually, therefore as by improving the structure of assembling caliper type supporting frame, make a kind of Portable support shelf structure be fit to simultaneously multiple light equipment and use, the versatility of raising assembling caliper type supporting frame, to greatly increase work efficiency, reduce cost.

How to address this problem and just become the problem that those skilled in the art will study and solve.

Summary of the invention

Purpose of the present invention is exactly the deficiency that exists for existing design, a kind of novel Portable support shelf structure improvement project is provided, makes every effort to improve the versatility of supporting frame, the light equipment that is fit to various shapes and size uses, convenient and practical, the height of increasing work efficiency reduce cost.

The present invention realizes by such technological scheme: a kind of Portable support frame, it is characterized in that, be the opening clamp by injection molding, the open card daughter backplane respectively and two angles that card forms between the arm, angle is acute angle, two card arm shapes are identical, mirror image is symmetrical, the uncovered valgoid that is in upper end of two card arms, the top processing contracting shoulder of two card arms has installation screw on the base plate of opening clip;

Under external force, the angles of two cards arm and base plates change, and after losing under external force, two are blocked arm under the flexible effect of self material, return to original position, thereby block supported equipment;

The Portable support frame is installed and using method, comprises the steps:

The first step is fixed on the Portable support frame on the immobilization carrier of required mounting point first by screw, installation screw;

Second step directly pushes the valgoid open-mouth of supported equipment by two card arms upper ends in the opening clamp and to tighten.

The invention has the beneficial effects as follows: the Portable support shelf structure adopts the non-metallic material injection molding process to make, the card arm can produce larger resiliently deformable, the thing that is installed is tightened easily do not damage by card beyond the region of objective existence surface the object in irregular shape of the quick loading and unloading requirement that is particularly useful for being installed.

Embodiment

For a more clear understanding of the present invention, describe in conjunction with the accompanying drawings and embodiments the present invention in detail:

Extremely shown in Figure 8 such as Fig. 1, a kind of Portable support frame, be opening clamp 1 by injection molding, opening clamp 1 base plate 14 respectively and the angles that form between two card arms 11, angle is acute angle, two card arm 11 shapes are identical, mirror image is symmetrical, the upper end uncovered 15 of two card arms 11 is valgoid, and the top processing contracting shoulder 12 of two card arms 11 has installation screw 13 on the base plate 14 of opening clip 1;

Under external force, two card arms 11 change with the angles of base plate 14, and after losing under external force, two card arms 11 return to original position, thereby block supported equipment 3 under the flexible effect of self material;

The Portable support frame is installed and using method, comprises the steps:

The first step is fixed on the Portable support frame on the immobilization carrier 2 of required mounting point first by screw, installation screw 13;

Second step directly pushes opening clamp 1 interior chucking with supported equipment 3 by two uncovered 15 places of valgoid that block arm 11 upper ends.

According to the above description, can realize the solution of the present invention in conjunction with art technology.
