Detailed ways

The technical solution of the utility model will be clearly disclosed through the description of the preferred embodiments of the utility model below.

The opening and locking structure of a folding furniture of the present utility model is shown in Figure 1a and Figure 1b. A foldable panel 110 and a second foldable panel 120 can be unfolded through a folding shaft. The part shown in FIG. 1a is a partial enlarged view of part A of the part shown in FIG. 1b.

The unlocking and locking structure is shown in FIG. 1a, FIG. 2a and FIG. 2b, and is arranged between the first foldable panel 110 and the second foldable panel 120, and includes an engaging piece 112 with a cut-off portion 111, Fixed on the first foldable panel, it can be set as a single-piece structure; as shown in the figure, it is better to adopt a double-piece structure, and the engaging piece 112 is set as an arc segment, and the The cut-off portion 111 is a discontinuous portion provided on the arc segment, such as a nearly vertical corner provided in this embodiment.

Simultaneously, an adapter sheet 122 with an exit channel 121 is also provided, as shown in Fig. 1a, Fig. 2a and Fig. 2b, the adapter sheet 122 is fixed on the second foldable panel 120, and is connected with the card The joint pieces 110 are pivotally connected in the coaxial direction of the folding shaft, and the pivot shaft is designated as 180, so that when the first foldable panel and the second foldable panel rotate around the folding shaft to open or close the desktop, the The matching piece 122 and the engaging piece 112 rotate relative to each other according to the pivot axis.

The opening and locking structure of the present utility model also includes an elastically supported pin shaft 130, as shown in Fig. 1a, Fig. 2a and Fig. The matching piece 122 is withdrawn from the disengagement channel, and snapped into the cut-off portion 111 to keep the first foldable panel and the second foldable panel in a flat unfolded state; the elastic pin 130 is pushed out of the cut-off portion 111, When entering the exit passage 121 , the folding furniture can be closed by folding the first foldable panel and the second foldable panel.

The elastic pin shaft 130 realizes the above-mentioned action of being pushed out of the cut-off portion 111 through a pressing handle 140, and the pressing handle 140 is pivotally connected with the engaging piece 112, as shown in Fig. 1a, Fig. 2a and Fig. 2b. The pivot axis can be set to be consistent with the pivot axis between the engaging piece and the adapter piece, and a circular arc fitting channel 141 is provided on the pressing handle 140, which is compatible with the withdrawal channel 121 and the The position of the cut-off part 111 intersects and can be adapted to the elastic pin 130 at the same time (at this time, the folding desktop is in an open and locked state); when the pressing handle 140 is pressed by hand, the arc fits the circle of the channel 141 The arc is configured to push the pin shaft 130 out of the cut-off portion 111 and move backward along the exit passage, thereby releasing the locked state. At this time, the first foldable panel and the second foldable panel can be Fold it away.
