The above structure can be used as a bed or a bed frame when the first frame, the second frame and the third frame are fully unfolded, and can be used as a bed or a bed frame when the first frame, the second frame and the third frame are fully folded. Used as a table or table stand, it is easy to use, and when folded, it is small in size and takes up less space.

When the overall structure is used as a bed or bed frame, the connection position of the second frame and the third frame is easily damaged by force compared to other positions. Therefore, the applicant also set the end of the connection between the second frame and the third frame. A foldable fourth vertical support frame 110, the fourth vertical support frame can be connected with the second frame by using a 90° hinge, or can be connected with the second frame by a pin shaft as shown in FIG. 1 and FIG. 2, The rotating shaft of the hinge is connected by a telescopic rod, of course, other existing methods can also be used, which are well known to those skilled in the art and will not be repeated here. In the fully folded state, in order to enable the first frame, the second frame and the third frame to be horizontal, the height of the first vertical support frame is smaller than the height of the second vertical support frame; the second vertical support frame The height of the support frame is equal to the height of the third vertical support frame; the height difference between the first vertical support frame and the second vertical support frame is equal to the thickness of the second frame.

As a preferred embodiment, referring to FIG. 2 , the second vertical support frame is provided with a corner plate 112 , which is a plate with corners. The corner plate is used here mainly to make the corner plate 112 after folding and unfolding. It is located below the second frame to prevent it from affecting the leveling of the bed frame or the table top. One end of the corner plate is connected to the second vertical support frame, and the other end is connected to the second frame that is not connected to the third frame. One end is connected, and the gusset plate generally includes two, which are arranged on both sides of the second vertical support frame and are located on the top of the second vertical support frame.

In this embodiment, the first hinge point O is preferably located at the longitudinal support leg close to the One end of the transverse connecting piece; the end of the transverse connecting piece that is not connected with the longitudinal support leg is hinged with a locking piece 3, one end of the locking piece is provided with a chute C, and the other end of the locking piece is connected to the The transverse connecting piece is hinged, and the hinge position is the second hinge point D; the sliding groove is provided with a first card slot A and a second card groove B that communicate with the The two card grooves and the sliding groove form an F-shaped structure, and the distance from the second card groove to the second hinge point D is greater than the distance from the first card groove to the second hinge point D; A horizontal support frame is provided with a positioning pin P that cooperates with the chute. When the first support leg is in a folded state, the positioning pin is located in the second slot, and the first support leg is unfolded. In the state, the positioning pin is located in the first slot.

In the above structure, when the first support leg is in the folded state, referring to FIG. 4 and FIG. 7 , the positioning pin P is located in the second slot, and the foldable frame will not move down due to the action of the second slot. When the first support leg needs to be unfolded, refer to Figure 5 and Figure 8, move the locking piece upward to make the positioning pin P contact with the chute C of the locking piece, rotate the first support leg, and the first support When the first support leg reaches the limit position, referring to Fig. 6 and Fig. 9, the locking plate is pushed down so that the positioning pin P is located in the first position. In the second card slot, the first support leg is locked, and the foldable frame will not move. This structure does not need to use a torsion spring, so there is no situation in which the table shakes during use due to the loosening of the torsion spring.

In actual production, the relative positions of the first groove, the second groove and the positioning pin can be set according to the existing production method, the locking piece is hinged to the first horizontal support frame and the positioning pin is fixed in the chute, Using the experimental method, take the first hinge point as the rotation center, rotate the locking piece, and record the position of the positioning pin when the first support leg is in the folded state, which is the connection point of the first groove and the chute. The position of the positioning pin recorded on the support leg in the unfolded state is the position of the connection point between the second groove and the chute. Of course, the relative positions of the first groove, the second groove and the positioning pin can also be set by calculation. It can also be set by means of simulation, which is well known to those skilled in the art, and will not be repeated here.

As a specific implementation manner, the height of the positioning pin is greater than the height of the first hinge point, and the height difference between the positioning pin and the first hinge point is smaller than that of the first hinge point and the second hinge point point distance; when the first support leg is in a folded state, the first card slot and the second card slot are located above the chute. This structure facilitates the movement of the positioning pin in the chute.

As a specific embodiment, the two first support legs located at one end of the first horizontal support frame are connected by the first support rod 4, so that the connection of the two first support rods at the same end makes the overall frame more stable, In the present application, the first horizontal support frame may be plate-shaped, which is applied to a common folding table as a desktop. As a preferred solution, the first horizontal support frame includes two horizontal Both ends of the support rod are connected with second support legs 5, and the two second support legs located at the same end of the lateral support rod are connected by the second support rod 6; Above the bottom end of the supporting leg; the bottom end of the first supporting leg is located below the bottom end of the second supporting leg when the first supporting leg is unfolded. When using this structure, only the second supporting leg can be used by folding the first supporting leg As the support of the table, the first support leg can also be opened as the support of the table, and whether to expand the first support leg can be selected according to people's requirements for different heights of the table. As a preferred manner, the first support leg is inclined in the unfolded state, and the distance from the top end to the center of the corresponding lateral support rod is smaller than the distance from the bottom end to the center of the corresponding lateral support rod; the first support leg is inclined. In the unfolded state, the support leg has a contact point T with the inner side of the corresponding second support leg, so that the contact point T further restricts the first support leg to continue to expand outward, which improves the overall stability of the table frame. When the inner side of the first support leg and the second support leg are in contact, it is used as the limit position of the first support leg to expand outward, as a reference for dialing down the locking piece, which is convenient for people to dial the locking piece downward to fix the table frame in time.
