Detailed Description

To facilitate an understanding of the present invention, it is described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 to 6, in the present embodiment, a flip folding stand includes a movable arm 2, a fixed arm 1, a support link arm 3, a guide slide 4, and an elastic buckle 5, wherein, as shown in the drawings, for convenience of description, both ends of the movable arm 2 are defined as a front end portion and a rear end portion, respectively, and both ends of the fixed arm 1 are defined as an upper end portion and a lower end portion. The rear end part of the movable arm 2 is pivoted with the upper end part of the fixed arm 1 through a first pin shaft 6, and the movable arm 2 rotates around the pin shaft relative to the fixed arm 1, so that the movable arm 2 and the fixed arm 1 are opened and closed, namely, when the movable arm 2 rotates upwards to a specified position relative to the fixed arm 1, the movable arm 2 and the fixed arm 1 are unfolded; conversely, when the movable arm 2 rotates downward to a specific position relative to the fixed arm 1, it means that the movable arm 2 and the fixed arm 1 are unfolded and folded.

In this embodiment, the fixed arm 1 is formed with a guiding sliding chute 21 extending along the length direction thereof, specifically, the bottom surface of the movable arm 2 is formed with a first receiving groove 11 extending along the length direction thereof, two inner side walls of the first receiving groove 11 are formed with two long grooves which are oppositely arranged in parallel and extend along the length direction of the movable arm 2, and the two long grooves at this time serve as the guiding sliding chutes 21 for slidably connecting two end portions of the guiding sliding shaft 4, respectively, so that the guiding sliding shaft 4 can move along the guiding sliding chutes 21.

In this embodiment, two end portions of the supporting link arm 3 are respectively pivoted to the fixed arm 1 and the guiding sliding shaft 4, specifically, a second accommodating groove 22 extending along the length direction is formed in the front surface of the fixed arm 1, and one end portion of the supporting link arm 3 is disposed in the second accommodating groove 22 and is pivoted with the fixed arm 1 through a preset second pin 7; secondly, the guide sliding shaft 4 penetrates through one end part of the support connecting arm 3 to realize pin joint matching, so that during the opening and closing action of the movable arm 2 and the fixed arm 1, the two end parts of the support connecting arm 3 correspondingly rotate around the second pin shaft 7 and the guide sliding shaft 4, and one end of the guide sliding shaft can drive the guide sliding shaft 4 to move along the guide sliding groove 21, so that the movable arm 2, the fixed arm 1 and the support connecting arm 3 form a connecting rod kinematic pair.

In the embodiment, the elastic fastener 5 is pivotally connected to the guiding sliding shaft 4 (the elastic fastener 5 is pre-opened with a through hole for the guiding sliding shaft 4 to pass through), that is, the elastic fastener 5 moves along the guiding sliding slot 21 along with the guiding sliding shaft 4. Next, the fixing arm 1 is provided with a locking hole 24 for the elastic fastener 5 to engage and cooperate (the locking hole 24 of the embodiment is provided on the inner top surface of the first accommodating groove 11). Specifically, when the movable arm 2 and the fixed arm 1 are in the unfolded state, the elastic fastener 5 moves to a predetermined position along with the guide sliding shaft 4 and is just aligned to and clamped into the locking hole 24 (taking the attached drawing as an example, the elastic fastener 5 is clamped into the locking hole 24 counterclockwise at this time), so that the elastic fastener 5 can be clamped with the locking hole 24, the stopper limits the guide sliding shaft 4 to move along the guide sliding groove 21, the locking effect is realized, the movable arm 2 is limited to be turned up or down relative to the fixed arm 1, and the support connecting arm 3 supports the movable arm 2 and the weight borne by the movable arm 2.

Furthermore, by pressing the elastic fastener 5 to rotate around the guide sliding shaft 4, the elastic fastener 5 is made to exit from the locking hole 24 (taking the attached drawing as an example, the elastic fastener 5 at this time is rotated clockwise to exit from the locking hole 24), so that the unlocking effect is realized, the movable arm 2 at this time is no longer limited and can be turned over relative to the fixed arm 1, and then the movable arm 2 and the fixed arm 1 are folded.

In this embodiment, the present invention further includes a torsion spring 8 sleeved on the guiding sliding shaft 4, wherein two legs of the torsion spring 8 respectively support against the supporting connecting arm 3 and the elastic fastener 5, so as to drive the elastic fastener 5 to move counterclockwise by using an elastic force generated by the torsion spring 8 on the elastic fastener 5, so that the elastic fastener 5 can be aligned to the locking hole 24 and be locked therein. Secondly, the user presses the elastic fastener 5 to overcome the elastic force of the torsion spring 8 to drive the elastic fastener 5 to rotate out of the indicated hole.

Further, in order to improve the bearing support capacity of the support arm to the movable arm 2 in the unfolded state, the two support arms of the present embodiment are arranged in parallel, and the two end portions of the two support arms are correspondingly pivoted on the same second pin shaft 7 and the same guide sliding shaft 4.

In this embodiment, when the movable arm 2 and the fixed arm 1 are in the retracted state, the first receiving groove 11 is used for receiving the support link arm 3, the guide sliding shaft 4 and the elastic fastener 5; when the movable arm 2 and the fixed arm 1 are in the folded state, the second receiving groove 22 can be used for the movable arm 2, so that the movable arm 2, the fixed arm 1 and the support connecting arm 3 can be completely or partially folded and overlapped together through the receiving effects of the first receiving groove 11 and the second receiving groove 22, and the turnover folding frame can reduce the occupied space as much as possible after being folded, and particularly reduce the thickness in the folded state.

In this embodiment, the bottom surface of the movable arm 2 is formed with a clearance 23 for accommodating the second pin 7, so that when the movable arm 2 and the fixed arm 1 are in the folded state, the second pin 7 can be placed in the clearance 23, so that the fixed arm 1 and the support connecting arm 3 are folded and overlapped as much as possible, and the occupied space is further reduced.

In this embodiment, the foldable roll-over stand according to the above embodiments can be used in practical application scenarios such as wall-mounted storage boards, foldable window enclosures, foldable clothes hangers, and the like. In order to facilitate understanding of the above-described flip-fold stand, the following description will be given with reference to specific embodiments.

Referring to fig. 7, in the present embodiment, a wall-mounted foldable storage board includes a storage board 100 and a pair of foldable racks according to the above embodiments, and the foldable racks are disposed in parallel on two sides of the bottom surface of the storage board 100. Specifically, the bottom surface of the object placing plate 100 is connected with the movable arm 2 of the turning folding frame through fixing methods such as screws, glue, and buckles, and the fixed arm 1 is connected to the wall surface through fixing methods such as screws, so that the object placing plate 100 is correspondingly driven to be switched between the unfolding state and the folding state through synchronously turning the folding frame up and unfolding or turning the folding frame down. The object placing plate 100 in the unfolded state is in a horizontal state and can be used for bearing heavy objects; the storage plate 100 in the folded state is in a vertical state, is tightly attached to the front as much as possible, and occupies a small space.
