Description

Technical Field

[0001] This utility model belongs to the field of support structures, and specifically relates to a support structure. Background Technology

[0002] Triangular supports offer good support and are stable and reliable, making them widely used in various scenarios. Existing triangular supports consist of a vertical bar, a horizontal bar, and a strut. One end of the horizontal bar abuts against and is fixed to the vertical bar, while the two ends of the strut connect to the horizontal and vertical bars respectively, forming a triangular support structure. A drawback of this structure is that once the three bars are fixed, it cannot be used in certain devices that require shape changes. Utility Model Content

[0021] The components include a first crossbar 1, a roller groove 1a, a second crossbar 2, a second roller 2a, a first support rod 3, a second support rod 4, a third support rod 5, and a slide block 6. Detailed Implementation

[0022] like Figure 1-4 As shown, this embodiment includes a first crossbar 1, a second crossbar 2, a first support rod 3, a second support rod 4, and a third support rod 5.

[0023] In this embodiment, the second horizontal bar 2 is in a horizontal state and the first horizontal bar 1 is in a downward angled state, with the first horizontal bar 1 being in a relatively fixed state.

[0024] One end of the second crossbar 2 abuts against the first crossbar 1, and this end is hinged to the first crossbar 1.

[0025] The first support rod 3 is located below the hinge point between the second crossbar 2 and the first crossbar 1. One end of the first support rod 3 is hinged to the first crossbar 1, and the other end of the first support rod 3 is hinged to one end of the second support rod 4. The other end of the second support rod 4 is hinged to the bottom surface of the second crossbar 2.

[0026] The third support rod 5 is also located below the hinge point between the second crossbar 2 and the first crossbar 1, but above the first crossbar 1. One end of the third support rod 5 is hinged to the first crossbar 1, and the other end of the third support rod 5 is hinged to the middle of the second support rod 4.

[0027] When in use, if a vertically downward force is applied to the second crossbar 2, the third support rod 5 lifts the second support rod 4, and the second support rod 4, under the action of the first support rod 3, will be given an upward support force, so that the second crossbar 2 can withstand the vertically downward force, and thus the second support rod 4 can be used to carry objects.

[0028] Preferably, this embodiment also includes a slide block 6 that can slide along the length of the first crossbar 1 but cannot detach from the first crossbar 1. Specifically, a groove 1a is provided along the length of the first crossbar 1, and a first roller corresponding to the groove 1a is provided on the slide block 6. The first roller can slide within the groove 1a but cannot detach from the groove 1a.

[0029] Furthermore, in this embodiment, a strip-shaped through hole is provided on the first crossbar 1, and two opening grooves, namely rolling grooves 1a, are provided on each of the two sides of the through hole. The two rolling grooves 1a have a U-shaped cross section and their openings face each other. The slide block 6 is hollow or U-shaped, and first rollers are provided at both ends of both sides of the slide block 6.

[0030] The first support rod 3, the second support rod 4, and the third support rod 5 are all located inside the through hole. One end of the first support rod 3 is hinged to the lower end of the slide block 6. There are two third support rods 5, located on both sides of the second support rod 4. The other end of the third support rod 5 is hinged to the upper end of the slide block 6, and the lower ends of the two third support rods 5 are respectively hinged to both sides of the second support rod 4.

[0031] In this embodiment, a second roller 2a is also provided at one end of the first crossbar 1 corresponding to the rolling groove 1a. The second roller 2a is located inside the rolling groove 1a and can roll on the rolling groove 1a without leaving the rolling groove 1a. The second crossbar 2 can rotate about the axis of the second roller 2a.

[0032] Furthermore, it also includes a pull strap, one end of which is connected to the hinged end of the second crossbar 2 and the first crossbar 1, and the other end of which is located at the upper end of the first crossbar 1. The pull strap is equipped with a winding mechanism that can retract the pull strap by winding it. The retraction of the pull strap pulls the hinged end of the second crossbar 2 to move upwards along the first crossbar 1. This upward movement of the second crossbar 2 causes the angle between the first support rod 3 and the second support rod 4 to widen until they approach a horizontal state, thus serving to retract the support structure. During the retraction process, the first crossbar 1 and the second crossbar 2 gradually become parallel until they overlap. In other embodiments, a pull rope can be used instead of a pull strap.

[0033] It should be noted that the terms of "upper," "lower," "top," "bottom," "front," and "rear" used in this application are all based on the accompanying drawings in the specification and are only used to clearly and simply express the technical solution, and do not imply any limitation on the scope of protection.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
