[0032] Embodiment: A mobile support leg longitudinal storage structure, comprising a support base 1 and a support leg 2, one end of the support leg 2 is rotatably mounted on the support base 1 around a rotation shaft perpendicular to the inclined positioning surface, the other end of the support leg 2 is provided with a supporting foot capable of being supported on a horizontal surface, and a stop connecting piece is further provided, which can fixedly connect the support leg 2 and the support base 1.

[0033] By rotating the support leg around the rotation shaft which has an angle with the horizontal surface, the support leg 2 can be extended in the horizontal direction or along the vertical direction, thereby realizing the unfolding and folding of the support leg 2. When the support leg 2 is in the horizontal unfolding state, the support leg 2 and the support base 1 are fixedly connected through the stop connecting piece, and when folding, the stop connecting piece is opened, and the support leg 2 can be rotated for folding. The inclined positioning surface is best at an angle of 45 degrees with the horizontal surface, so that the rotation shaft also forms an angle of 45 degrees with the horizontal surface, and the support leg 2 can be converted between the two states of parallel to the horizontal surface and perpendicular to the horizontal surface. This structure is simple, has few parts, and can easily realize the quick unfolding or folding of the support leg 2 of the support through only one rotation, is convenient to use, simple to operate, and less likely to malfunction.

[0034] A convex column 4 having a set angle with the horizontal direction is formed on the edge of the support base 1, and the end face of the convex column 4 forms an inclined positioning surface having a set angle with the horizontal surface, and one end of the support leg 2 is mounted on the inclined positioning surface of the convex column 4. This structure improves the strength of the connection position of the support leg 2 on the support base 1, and avoids interference between the support leg 2 and the support base 1 during rotation.

[0035] The support leg 2 is formed with an inclined contact surface at one end, which is in close contact with the inclined positioning surface of the convex column 4. The close contact between the two inclined surfaces enhances the connection strength, stability and firmness of the support leg 2 when it is unfolded horizontally. The inclined positioning surface of the bracket base 1 also supports and holds the one end of the support leg 2 when the support leg 2 is unfolded, which reduces the shear force of the rotating shaft between the support leg 2 and the bracket base 1, prevents the rotating shaft from being broken or deformed due to the weight pressure on the bracket base 1, and causes the gap to be too large, which weakens the connection strength between the bracket base 1 and the support leg 2, further improves the support stability of the support leg 2, and also realizes the stable storage of the support leg 2 in the folded state through the friction between the inclined surfaces of the support leg 2 and the bracket base 1. When the support leg 2 and the bracket base are made of metal, a plastic gasket is preferably arranged between the inclined contact surface of the support leg 2 and the inclined positioning surface of the bracket base for providing rotating friction of the contact surfaces. Of course, if the contact surfaces of the support leg 2 and the bracket base are made of plastic material.

[0036] The stopper connector includes a positioning hole 6 arranged on the bracket base 1 and a positioning pin 7 slidably arranged on one end of the support leg 2 along the depth direction of the positioning hole 6. The positioning pin 7 can be inserted into or pulled out of the positioning hole 6. After the support leg 2 is rotated to the unfolded support position, the positioning pin 7 and the positioning hole 6 are inserted to fix and position the support leg 2 and the bracket base 1. The positioning hole 6 can be arranged with one or multiple positioning holes for positioning the support leg 2 in the unfolded support state and the folded storage state, respectively. The above-mentioned positioning structure of the support leg 2 is simple and easy to operate. In addition, the positioning can also be achieved by screw connection or buckle fastening, which is an equivalent replacement structure easily thought of by those skilled in the art according to the present patent and belongs to the protection scope of the present patent.

[0037] An elastic member 8 and a pull ring 9 are further arranged. The positioning pin 7 is slidably arranged on one end of the support leg 2 by a certain distance. The elastic member 8 provides elastic holding force for the positioning pin 7 to keep the positioning pin 7 inserted into the positioning hole 6. The pull ring 9 is arranged on the positioning pin and exposed on the surface of the support leg 2. The positioning pin 7 can be elastically slid and extended and retracted by the elastic member 8, and always keeps the state of extending towards the positioning hole 6 when subjected to external force. The positioning pin 7 can be automatically inserted into the positioning hole 6 to position the support leg 2 and the bracket base 1 when the support leg 2 is rotated to the unfolded state. When folding is needed, the positioning pin 7 can be pulled out of the positioning hole 6 by pulling the pull ring 9. The structure is simple, easy to operate, and can automatically position, which is safe and stable to use.

[0038] The support base is further provided with an arc-shaped positioning bolt slide 10, the positioning bolt 7 can slide along the extension direction of the positioning bolt slide 10, the bottom surface of the positioning bolt slide 10 is an arc-shaped inclined surface with one end lower than the other end, and the other end of the bottom surface of the positioning bolt slide 10 is aligned with the plane where the positioning hole 6 is located on the support base. The positioning bolt 7 forms an elastic bolt structure under the action of the elastic member 8, after being lifted out of the positioning hole 6 by external force, the support leg 2 is rotated, the positioning bolt 7 enters the inner side of the other end of the arc-shaped positioning bolt slide 10, along with the rotation of the support leg 2, the positioning bolt 7 slides along the positioning bolt slide 10, at the same time, the elastic force of the elastic member 8 is gradually released, when the support leg 2 reaches the folded vertical position, the positioning bolt 7 just reaches one end of the positioning bolt slide 10, at this time, the slide pin forms an elastic extension state, in order to make the support leg 2 rotate in the opposite direction, the positioning bolt 7 needs to slide in the opposite direction, the positioning bolt 7 needs to overcome the elastic force of the elastic member 8, therefore, without external force rotating the support leg 2, the support leg 2 will maintain a stable folding state, the structure design is ingenious, which not only guides the sliding of the positioning bolt 7 while the support leg 2 is rotating, but also realizes the elastic positioning of the support leg 2 after folding, avoids free rotation out of the folding state, and releases the elastic force of the elastic member 8 in the folded state, prevents the elastic member 8 from being invalid due to long-term pressure, when the support leg 2 is unfolded, the positioning bolt 7 can enter the positioning hole 6 for positioning along the inclined bottom surface of the positioning bolt slide 10, the structure ensures the stability of unfolding and folding of the support leg 2, and is simple in structure and convenient to operate.
