Detailed ways

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

As shown in Figures 1 to 2, a support frame of the present invention mainly includes a main frame body 1 and a sub-frame body 2 connected to the side of the main frame body, and the main frame body 1 includes two groups of left and right sides A bracket 11 and a middle bracket 12 located in the middle, two symmetrical panels 3 are connected above each bracket of the main frame body 1 .

Wherein, the side support 11 includes two legs 111 juxtaposed, the middle bracket 12 includes two legs 121 juxtaposed, and a group of sub-frame bodies 2 are connected on the sides of one group of side brackets 11, and the sub-frame body 2 includes two legs. 21. An upper rod 22 is movably connected between the top of the leg 21 and the leg 121, and a cross bar 23 is movably connected between the two upper rods 22 or a panel is directly covered, so that the support frame is on the basis of the main frame body 1 , the use of at least one sub-frame body 2 increases the use area of the support frame.

In the utility model, in order to make the support frame formed by the combination of the main frame body 1 and the sub-frame body 2 reach foldable, in this embodiment, the adjacent two legs of each adjacent bracket in the main frame body 1 are connected There is a group of movable cross support rods 4, cross support rods 4 are also connected between the sub-frame body 2 and the legs of the side brackets 11, and one end of the two panels 3 is pivotally connected to the top of the middle bracket 12. As shown in Fig. 1 and Fig. 2, the cross strut 4 includes two cross struts 41 cross-connected on the inner surface of the legs, the lower ends of each cross strut 41 are fixed on the bottom of the legs, and the upper ends of the cross struts 41 are connected on a slide Set on the movable block 42 on the support leg, the ends of the two overlapped cross struts 41 are pivotally connected and superimposedly connected. For the two intersecting cross struts 41 at the middle leg 121, the lower ends of the two cross struts 41 are pivotally connected and superimposed, and the upper ends of the two cross struts 41 are connected to the movable block at one of the cross struts 41. 42, the upper end of another cross strut 41 is superimposed and connected on the same movable block 42 after being pivotally connected with the aforementioned cross strut connected on the movable block 42, so that the two cross struts 41 can go upward at the same time. Or move downwards to make the cross support bar 4 close. In the same way, on the legs 111 of the side brackets 11 connected with the sub-frame body 2, because it is the junction of the cross support rods 4 on both sides, a sub-frame is also pivotally connected above a cross support rod 41 connected on the movable block 42. The upper end of a cross strut 41 of the body 2, the upper end of the cross strut 41 of the sub-frame body 2 is also connected to a movable block 42 that is slidably arranged on the side bracket legs, so the upper ends of the two cross struts 41 are pivotally connected. The back is superimposed and connected on the same movable block 42, so that the three groups of cross support rods move up and down under the action of the movable block to realize deployment and retraction.

It should be noted that when the sub-frame body 2 is used separately from the main frame body 1, the cross support rods 4 connected to the side brackets 11 in the sub-frame body 2 are independent, and do not cross with the cross braces in the main frame body 1. The support rods 4 are connected. At this time, the upper end of a cross strut 41 in the subframe body 2 is connected on a first movable block that is slidably arranged on the side support legs, and a cross strut in the main frame body 1 The upper end of 41 is connected to the second movable block (not shown in the figure) on the side support leg 111, and the first movable block is located above the second movable block. When leaning or unfolding, the sub-frame body 2 can be selectively unfolded and then stowed, so the sub-frame body 2 can be folded or unfolded according to usage requirements to increase the use area of the support frame.

Further, in order to make the movable block 42 not slide down to the lower end of the leg when the legs of each support are launched and erected, a stopper 421 for erecting the movable block is provided below each support leg, and the movable block 42 is erected on the stopper 421 To support the cross bracing bar 4 that expands. Each bracket in the utility model can also be set as a telescopic frame rod to adjust the height of the support frame. In the present embodiment, a telescopic rod is connected above each bracket leg in the main frame body 1, as shown in Figure 1 A telescopic rod 112, a compression spring (inside the rod, not shown in the figure) is provided between the telescopic rod 112 and the support foot 111, and a positioning hole 422 for locking and positioning the telescopic rod is provided above the support leg 111, and the telescopic rod 112 can be placed on the Use the desired extension to raise the height of the feet, allowing the stand to be height-adjustable.

In order to make the supporting effect between the legs of each support more stable, a horizontal support rod 44 is horizontally arranged between the front and rear two legs of the same support, and the two ends of the horizontal support rod 44 are respectively connected to the two relative movable blocks 42 above. Connected cross struts 41.

Because the top of the main frame body 1 is connected with two symmetrical panels 3, the two panels 3 are also folded downward when the brackets of the main frame body 1 are closed and folded, and one end of the two panels 3 is pivotally connected to the middle bracket 12. above, and the other end is erected above the side support 11. A connecting piece 50 is connected above the support foot 121 of the middle bracket, and a torsion spring 51 is connected between the connecting piece 50 and the panel 3, and the torsion spring 51 can limit the panel 3 from falling instantly when it is folded downward, so that it can be slowly retracted , when the support frame is folded, lightly press down the two panels 3, and the torsion spring 51 is bent downward so that the two panels 3 are folded against the two sides of the main frame body 1, as shown in Figure 2 .

When the bracing frame of the present utility model is in use, because the bracing frame includes the main frame body 1 and the sub-frame body 2 connected thereto, when folding, the sub-frame body 2 is first received against the side support 11. If the sub-frame body 2 is used separately from the main frame body 1, the cross support bar 4 connected with the side bracket 11 in the sub-frame body 2 is independent, and it is not connected with the cross support bar 4 in the main frame body 1 , when it needs to be used, unfold it as a sub-frame body 2 and stand beside the side bracket 11, and when it is not in use, directly close it to the side without affecting the use of the main frame body 1 of the support frame, and the use has options sex. In the present embodiment as shown in Fig. 1, three groups of cross support rods 4 are connected. The upper upper rod 22 is folded downwards, and it can be placed next to the legs 111 of the side bracket 11, and then the side bracket 11, the middle bracket 12 and the sub-frame body 2 are concentrated inwardly by utilizing the telescopic effect of the cross support rod 4. , and finally fold down the panel 3 above the main frame body 1 to complete the folding of the support frame, as shown in FIG. 2 . On the contrary, the support frame can be unfolded for use.

The above-mentioned embodiments and drawings do not limit the product form and style of the present utility model, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present utility model.
