[0026] Embodiment: A portable hidden telescopic support leg structure includes a box body 1, support legs 2 and fasteners 3, wherein a cavity structure is formed inside the box body 1, and the support legs 2 can be accommodated and hidden in the cavity structure of the box body 1, and one end of at least two support legs 2 can be fixedly connected to the lower end of the box body 1, and each support leg 2 is evenly distributed at the lower end of the box body 1 along the circumferential direction of the box body 1 and supports the box body 1.

[0027] When the vertical stand is used to install a large-size display, one end of the support leg 2 can be fixedly connected to the lower end of the box body 1. Two or more support legs 2 (preferably three or more evenly distributed around the box body 1 to improve support stability) can form a stable support for the box body 1, expand the support area, and achieve stable support when installing a large-size display. When the vertical stand is used for a small-size display or for storage, the fastener 3 can be opened and the support leg 2 can be placed in the cavity structure in the box body 1 for storage. This structure makes the vertical stand have a wide range of applications, flexible use, and easy storage, transportation and carrying.

[0028] The other end of the support leg 2 is provided with a universal wheel 4. After the support leg 2 is fixedly mounted on the box body 1, the vertical support position can be easily moved through the universal wheel 4, which is conducive to freely changing the display position and direction of the display as needed.

[0029] At least two groups of slide grooves 5 with openings at the lower ends extending in the longitudinal direction are provided on the inner side wall of the box body 1, and the support legs 2 can be slidably inserted into the slide grooves 5 one by one. When the support legs 2 are stored, each support leg 2 is correspondingly inserted into a slide groove 5 to prevent the support legs 2 from shaking and colliding in the box body 1, and to prevent the support legs 2 and the inner side wall of the box body 1 from being damaged. In order to accommodate the support legs 2 and the universal wheels 4 thereon, a size expansion structure can be formed at the lower end of the slide groove 5 to accommodate the universal wheels 4.

[0030] The two opposite side walls of the slide groove 5 are respectively provided with groove structures 6 extending in the longitudinal direction, and the two opposite side walls at one end of the support leg 2 are fixed with hinge shafts 7, and the hinge shaft 7 can be slidably inserted in the groove structure 6, and the hinge shaft 7 can rotate in the groove structure 6, and a stop surface is provided at the lower end of the groove structure 6, and the hinge shaft 7 stops on the upper side of the stop surface, and the upper side surface of the support leg 2 stops on the side wall of the box body 1 or the lower end surface of its internal structure. When in use, it is only necessary to pull the supporting leg 2 to make the supporting leg 2 slide in the slide groove 5, while the hinge shaft 7 slides synchronously in the groove structure 6. When the hinge shaft 7 slides to the bottom, it is blocked by the stop surface at the lower end of the groove structure 6 and cannot continue to slide downward. At this time, the supporting leg 2 rotates around the hinge shaft 7, and the upper surface of the supporting leg 2 is attached to the end surface of the lower end of the side wall of the box body 1. At this time, a force balance is formed on the supporting leg 2, which can support the box body 1. This structure ensures that the supporting leg 2 and the box body 1 are always connected and will not detach from each other, thereby avoiding the loss of the supporting leg 2. The intersection shaft will bear the load together with the fastener 3, which greatly reduces the tension borne by the fastener 3 and avoids damage to the fastener 3.

[0031] The upper side of one end of the support leg 2 forms a contoured surface structure that matches the outer shape of the lower end face of the side wall of the box body 1 or its internal structure. When the hinge shaft 7 is in close contact with the upper surface of the stop surface, the contoured surface structure on the upper side of one end of the support leg 2 is just in close contact with the lower end face of the side wall of the box body 1 or its internal structure. This structure allows the support leg 2 to slide down to the bottom of the intersection shaft on it, and it can be in close contact with the lower end face of the side wall of the box body 1 to avoid warping. The lower end face of the side wall of the box body 1 is preferably a plane, and the square surface on one end of the support leg 2 is also a plane. This structure is easy to process and has stable support. The lower end of the side wall of the box body 1 can be provided with a notch structure 8 corresponding to the support leg 2 one by one, and the support leg 2 can extend to the outside of the box body 1 through the notch structure. In this way, the notch structure can also limit the left and right side walls of the support leg 2, thereby improving the installation strength and stability of the support leg 2.

[0032] The structure in which one end of the support leg 2 is fixedly connected to the lower end of the box body 1 is as follows: a stopper 9 and an elastic member 10 are also provided, which can be rotatably installed on the inner side wall of the box body 1 or fixed on its internal structure around a horizontal axis. A barb structure is formed at the lower end of the stopper 9, and a reverse barb structure that can be snapped and connected with the barb structure at the lower end of the stopper 9 is formed on the support leg 2. The elastic member 10 provides an elastic holding force for the stopper 9 to maintain the snapping connection with the reverse barb structure. When the support leg 2 is turned from a vertical state to a horizontal support state, the barb structure of the stopper 9 is snapped and connected with the reverse barb structure on the support leg 2, and the elasticity will provide an elastic force to the barb structure, so that the barb structure and the reverse barb structure maintain a stable snapping connection state. A U-shaped positioning member 11 can be fixedly installed on the inner side wall of the box body 1, and the upper end of the stopper 9 is hinged to the positioning member through a pin 12, so as to realize the installation of the stopper 9 on the inner side wall of the box body 1.

[0033] The support leg 2 is provided with a hollow portion 13, and the barb structure at the lower end of the stopper 9 can pass through the hollow portion and stop on the lower side wall surface of the support leg 2. The hollow portion on the support leg 2 and its lower side wall form a reverse barb structure. In addition to the reverse barb of the hollow portion, it can also be an inverted L-shaped convex block structure, which is an equivalent replacement structure that can be easily thought of by those skilled in the art based on this patent and falls within the protection scope of this patent.

[0034] The structure in which one end of the support leg 2 is fixedly connected to the lower end of the box body 1 is as follows: a sliding pin 14 and an elastic member 10 are installed on the inner side of the box body 1 or installed in its internal structure and can slide along the longitudinal direction to set a distance. A limited hole is formed on the upper side wall of the support leg 2, and the sliding pin 14 can be inserted into and withdrawn from the limited hole. The elastic member 10 provides an elastic retaining force to keep the sliding pin 14 inserted into the limited hole. The elastic sliding pin 14 is plugged into the limited hole to achieve snap-fit ​​connection and positioning. A U-shaped positioning member can be fixedly installed on the inner side wall of the box body 1, an opening is provided on the lower bottom surface of the positioning member, and a radial convex ring is provided on the circumferential outer wall of the sliding pin 14. The sliding pin 14 is inserted into the opening on the positioning member, and the radial convex ring on the circumferential outer wall of the sliding pin 14 is stopped by the bottom surface of the positioning member to prevent it from falling out. The elastic member 10 is pressed against the upper end of the radial convex ring, so that the sliding pin 14 always maintains a snap-fit ​​state with the upper limit hole of the support leg 2.

[0035] The structure in which one end of the support leg 2 is fixedly connected to the lower end of the box body 1 is as follows: a screw 15 is also provided, a threaded hole is provided on the lower end surface of the box body 1, and a through hole is provided on the side wall of the support leg 2. The screw 15 passes through the through hole on the support leg 2 and is finally movably screwed to the threaded hole, and the head of the screw 15 is tightly against the lower surface of the support leg 2.

[0036] A cover plate 16 is also provided, which is detachably fixed to the lower end of the box body 1, and the cover plate 16 can cover the opening of the chute 5 at the lower end of the box body 1. After the support leg 2 is stored in the box body 1, the cover plate 16 closes the opening of the chute 5 to prevent the support leg 2 from falling out.
