Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to the attached drawings 1 to 17 in the specification, a connection structure for reducing shaking comprises a panel 1 and two support frames 2 which are connected with each other, wherein a groove 10 is arranged on the panel 1, and two opposite side edges of the panel 1 are respectively provided with a cross rod assembly 11; the supporting frame 2 comprises a first supporting leg 21, a second supporting leg 22 and a connecting rod 23 connected to the top ends of the first and second supporting legs, the connecting rod 23 is inserted into the opening 11a of the cross bar assembly 11 for connection, wherein the connecting rod 23 is a circular tube, a part of the connecting rod 23 is flattened to form a mounting portion 23a, the mounting portion 23a is disposed in the groove 10, wherein the cross section a of the mounting portion 23a is a non-circular cross section, and the cross section a has a long axis portion a1 and a short axis portion a2 with different lengths. Because the connecting rod 23 and the cross rod assembly 11 are connected with a gap, the shaking of the panel is very easy to cause when a user uses the device, the utility model matches the mounting part with the bottom of the groove, the long shaft part a1 of the mounting part can be directly contacted and propped against the bottom of the groove 10, thereby the height of the connecting rod is improved, and the gap is reduced; preferably, the section a is elliptical, and the highest point of the major axis portion a1 can prop against the bottom of the groove 10, so that the gap between the connecting rod 23 and the upper edge of the opening 11a of the panel is reduced by 2-3 mm, that is, the connecting rod 23 is raised by 2-3 mm relative to the upper edge of the opening 11a, and the connecting rod is directly contacted and matched with the upper edge b1 of the opening of the panel, thereby reducing the shaking. Preferably, the first and second mounting portions are partially disposed on the mounting portion 23a, and the first and second mounting portions are engaged with the two grooves 10 on the respective panels, so as to further ensure the reliability of the operation.

Specifically, referring to the drawings, opposite ends of the connecting rod 23 are hinged to the cross bar assembly 11, for example, opposite ends of the connecting rod 23 are inserted into openings of the cross bar assembly 11, so that the connecting rod 23 can rotate around the cross bar assembly 11. Referring to the drawings, when the folding stand is in the folded or fully unfolded state, the long axis portion a1 of the setting portion is in the same direction as the first supporting leg 21; when the first or second support legs are unfolded to drive the connecting rod 23 to rotate, the long shaft part a1 of the connecting rod rotates along with the first or second support legs until the support legs are completely unfolded, the long shaft part a1 just props against the groove 10, so that the height of the connecting rod 23 is improved, the gap between the connecting rod and the cross rod assembly 11 is reduced, and the stability of the folding frame is enhanced (when the folding frame is folded, the connecting rod has a gap with the upper edge of the opening (refer to the attached figure 3), and after the unfolding frame is directly contacted and matched with the upper edge b1 of the opening of the panel (refer to the attached figure 15)).

Preferably, the height of the supporting frame 2 is adjustable, for example, the first supporting leg 21 includes an outer rod 21a and a sleeve rod 21b, the sleeve rod 21b is sleeved in the outer rod 21a and can extend and retract along the outer rod, and the extending and retracting manner is realized by using a locking member 21c to realize sliding or locking. The locking member 21c comprises a body 211 and a pressing assembly 212, the body 211 comprises an upper cavity and a lower cavity, a through hole is formed between the upper cavity and the lower cavity, the pressing assembly 212 comprises a key, a positioning rod and a spring, the positioning rod and the spring are respectively positioned at two opposite ends of the key, and the spring is arranged in the upper cavity; usable pin joint axle is articulated between this locating lever and the button, and the other end of this locating lever passes through the through-hole and cooperates the height-adjusting with a plurality of locating holes on the loop bar 21b, can set up the regulation of a plurality of locating holes realization co-altitude not on this loop bar, and like this, the user can adjust the height of these a little supporting legss as required, and is very humanized.

Further, in order to enhance the stability of the support frame, an inclined rod 24 may be installed between the locking member 21c and the cross rod assembly 11, the inclined rod 24 is disposed opposite to the pressing assembly 212, and the inclined rod 24 is hinged to the locking member 21c and the cross rod assembly 11, respectively, and is connected to rotate by a pin. Preferably, the locking member 21c further has a yielding portion g, and a connecting rod 26 passes through the yielding portion g to connect with the outer rod, so that the first and second supporting legs are connected together, the stability of the supporting frame is further enhanced, and the operational reliability of the locking member is also ensured.
