Description

Folding support frame Technical Field The utility model relates to the technical field of support frames, in particular to a folding support frame. Background In recent years, flexible tank structures (such as bathtubs, air conditioning hoods, portable reservoirs, etc. formed of tarpaulins) have been widely used in home, industrial and outdoor settings due to their lightweight, portability and rapid deployment characteristics. Such flexible tanks often require a rigid or semi-rigid support structure (i.e., a keel support) to maintain their in-use configuration, preventing collapse and deformation due to internal pressure irregularities or external forces. However, in the prior art, the support frame for supporting the flexible tank body mostly adopts an integral fixed frame structure, and the side wall of the tank body is restrained by the support frame made of metal or plastic materials. Although the design can provide stable mechanical support, the design has the obvious defects that the whole support frame can not fold the flexible tank body, the occupied space is large when the flexible tank body is not in use, the transportation and storage costs are high, and the support frame and the flexible tank body are detachably connected, but extra disassembly and assembly steps are needed, so that the operation is troublesome. Disclosure of utility model In order to solve the problems, the utility model provides the following technical scheme: The utility model provides a folding support frame, includes a plurality of fossil fragments boards, link to each other through the articulated elements in proper order between the fossil fragments board, the articulated elements be damping articulated elements or the articulated department of fossil fragments board is provided with locating component, and is a plurality of fossil fragments board includes the main joist board, both ends are articulated respectively about the main joist board have the auxiliary joist board, the auxiliary joist board is highly less than the height of main joist board towards main joist board one end. The damping hinge is further provided with damping hinges, two sides of each damping hinge are respectively fixed with two adjacent keel plates, and the damping hinges limit the rotation angle through friction force of interference fit or a damper. The positioning assembly is further arranged to comprise an L-shaped bolt movably arranged on the main keel plate and a slot arranged on the auxiliary keel plate, wherein the L-shaped bolt penetrates into the slot so as to limit the rotation angle of the auxiliary keel plate. The utility model is further characterized in that the support frame is provided with a connecting piece, and the connecting piece is used for hanging the support frame. The utility model is further characterized in that the keel plates are rectangular, the length of the main keel plate is greater than or equal to that of the auxiliary keel plate, and a plurality of keel plates are connected to form a semi-closed structure. The utility model is further arranged that the tops of the left end and the right end of the main keel plate are respectively provided with a first round corner, and the top of one end, far away from the main keel plate, of the auxiliary keel plate is provided with a second round corner. The main keel plate is further provided with reinforcing ribs, and the reinforcing ribs are formed by bending the main keel plate. The utility model is further characterized in that the top of the auxiliary keel plate is provided with a bending part which is horizontally arranged and vertical to the auxiliary keel plate, and the bending part is bent inwards. The utility model is further characterized in that the connecting piece is a hanging rope, and two ends of the hanging rope are respectively fixed on the side walls of the two auxiliary keel plates. The utility model is further arranged that one end of at least one auxiliary keel plate far away from the main keel plate is hinged with a third keel plate. Compared with the prior art, the utility model has at least the following advantages: 1. Including a plurality of fossil fragments boards can be fixed with the lateral wall of flexible cell body respectively through using the fastener, articulated through the damping hinge between the fossil fragments board, makes fossil fragments board can not take place to rotate easily, both can provide stable polygon bearing structure for flexible cell body, when needs are accomodate, can make fossil fragments board drive flexible cell body folding accomodate through applying external force again simultaneously, is showing to reduce storage and cost of transportation, and the operation is very convenient and fast still. 2. The height of the auxiliary keel plate towards one end of the main keel plate is set to be lower than that of the main keel plate, so that the support frame is more suitable for an air conditioner cleaning cover, th
