DETAILED DESCRIPTION

[0026] The utility model provides a multi-purpose new hinge structure component with 180-degree flat-angle flipping of a dislocation plate, which solves the problem that the existing hinges cannot be well applied to dislocation components, realizes a relatively dislocation flipping structure, and meets the complex functional requirements of the product.

[0027] See also Figure 1 , Figure 4 , Figure 6 The utility model discloses a multi-purpose hinge structure for 180-degree flat-angle flipping of a dislocation plate in one embodiment, comprising an upper flip movable member 11 and a lower flip movable member 12 arranged in a dislocation, wherein a first ear-shaped linkage clamping member 21 is rotatably connected to the upper flip movable member 11, and the other end of the first ear-shaped linkage clamping member 21 is rotatably and slidably connected to the lower flip movable member 12; a second ear-shaped linkage clamping member 22 is rotatably connected to the lower flip movable member 12, and the other end of the second ear-shaped linkage clamping member 22 is rotatably and slidably connected to the upper flip movable member 11. In this way, the two dislocation flip movable members are rotatably and movably connected together through the two ear-shaped linkage clamping members.

[0028] It can be understood that the descriptions of spatial states such as "above" and "below" in this article are merely illustrative definitions based on the embodiments of the accompanying drawings for the convenience of expression and understanding, and the present invention is not limited to this; the rotational connection means that the ear-shaped linkage clamping member can rotate relative to the flipping movable member; the rotatable sliding connection means that the end of the ear-shaped linkage clamping member can slide along a track, and that the end of the ear-shaped linkage clamping member does not translate along the track, but moves and rotates at the same time, so as to achieve the functional effect of flipping conversion between the retracted 0 degree state and the flat 180 degree state as shown in the figure.

[0029] For more information, see also Figure 2 , Figure 3 , Figure 5The upper flip movable member 11 includes an upright upper connecting plate 111, and the lower flip movable member 12 includes an upright lower connecting plate 121. The upper connecting plate 111 and the lower connecting plate 121 are arranged adjacent to each other, for example, located in the same vertical plane. The first ear-shaped linkage clamping member 21 and the second ear-shaped linkage clamping member 22 are located on both sides of the upper connecting plate 111 and the lower connecting plate 121 (in the structure shown in this embodiment, the first ear-shaped linkage clamping member 21 / the second ear-shaped linkage clamping member 22 can be located on either side, in other words, the side positions can be interchanged without affecting the working principle).

[0030] An upper shaft hole 112 and an upper sliding displacement groove 113 are provided on the upper connecting plate 111. The upper shaft hole 112 is located on the side of the upper sliding displacement groove 113 close to the lower connecting plate 121. The upper sliding displacement groove 113 is inclined and has an arc so as to better realize the required functional process. An upper shaft member 211 (such as a cylindrical shaft) is inserted into the upper shaft hole 112. One end of the first ear-shaped linkage clamping member 21 is rotatably connected to the upper connecting plate 111 through the upper shaft member 211, thereby forming a pivot connection; of course, there is also a limiting structure to ensure that the pivot connection is stable and will not fall apart. This enables the ear-shaped linkage clamping member to rotate around a fixed axis on the flip movable member.

[0031] The lower flip movable member 12 can optionally adopt a similar structure to realize the rotation connection. That is, the lower connecting plate 121 is provided with a lower rotating shaft hole 122 and a lower sliding displacement groove 123, and the lower rotating shaft hole 122 is located on the side of the lower sliding displacement groove 123 close to the upper connecting plate 111; the lower rotating shaft member 221 is inserted into the lower rotating shaft hole 122, and one end of the second ear-shaped linkage clamping member 22 is rotationally connected to the lower connecting plate 121 through the lower rotating shaft member 221. The first ear-shaped linkage clamping member 21 and the second ear-shaped linkage clamping member 22 are, for example, both in an arc shape.

[0032] As for the rotatably sliding connection structure at the other end, a first sliding shaft 212 (such as a pin shaft) is inserted into the strip-shaped lower sliding displacement groove 123, and one end of the first ear-shaped linkage clamping member 21 away from the upper shaft 211 is rotatably slidably connected to the lower sliding displacement groove 123 through the first sliding shaft 212; the first sliding shaft 212 is, for example, cylindrical and can rotate / slide in the lower sliding displacement groove 123. It is conceivable that, for example, a slider is strictly slidably connected in the sliding displacement groove, and the slider is rotatably connected to the ear-shaped linkage clamping member, which can also achieve the required function.

[0033] The second ear-shaped linkage clamping member 22 can optionally adopt a similar structure to achieve a rotatable sliding connection. That is, a second sliding shaft member 222 is inserted into the upper sliding displacement groove 113, and one end of the second ear-shaped linkage clamping member 22 away from the lower shaft member 221 is rotatably slidably connected to the upper sliding displacement groove 113 through the second sliding shaft member 222.

[0034] Furthermore, a limiting abutment portion for limiting the angle range between the upper flip movable member 11 and the lower flip movable member 12 is provided on the upper flip movable member 11, the second ear-shaped linkage locking member 22, the lower flip movable member 12 and the first ear-shaped linkage locking member 21, thereby achieving limitation in both the 0-degree retracted state and the 180-degree flattened state, and the structure can remain stable and stationary in these two states.

[0035] For example, the upper rotating shaft 211 extends out from the side of the upper connecting plate 111 close to the second ear-shaped linkage clamping member 22 to form an upper limiting protrusion; the second ear-shaped linkage clamping member 22 is provided with a second limiting abutment portion 223 (such as a concave notch) matching the upper limiting protrusion near the second sliding rotating shaft 222. Figure 2 As shown, in the 0-degree retracted state, the second limit abutment portion 223 and the end of the upper rotating shaft 211 are locked and limited; Figure 5 As shown, in the flattened 180-degree state, the second position-limiting abutting portion 223 leaves the upper position-limiting protrusion, and the second sliding shaft member is located at the end of the upper sliding displacement groove 113 to achieve position limiting.

[0036] The structure on the other side is similar. The lower rotating shaft 221 extends out from the side of the lower connecting plate 121 close to the first ear-shaped linkage clamping member 21 to form a lower limiting protrusion; the first ear-shaped linkage clamping member 21 is provided with a first limiting abutment portion 213 matched with the lower limiting protrusion near the first sliding rotating shaft 212. Thus, a double limiting function is performed to ensure the reliability of flipping and limiting positioning.

[0037] More specifically, the upper flip movable member 11 includes an upper mounting member 114 connected to the upper connecting plate 111 (e.g., vertically), and the lower flip movable member 12 includes a lower mounting member 124 connected to the lower connecting plate 121 (e.g., vertically). The upper connecting plate 111 and the lower connecting plate 121 are used to form the above-mentioned rotation connection, and the upper mounting member 114 and the lower mounting member 124 are used to install components such as furniture boards, and the upper mounting member 114 and the lower mounting member 124 have screw holes, for example.

[0038] See also Figure 3 , Figure 4 , Figure 6, an upper stopper 115 is provided on the upper mounting member 114 (e.g. vertically), and a lower stopper 125 is provided on the lower mounting member 124 (e.g. vertically). The upper mounting member 114 and the lower mounting member 124 are located on both sides of the upper connecting plate 111 and the lower connecting plate 121. The installed furniture panels and other components are pressed against the stopper to be installed in place, and the state after installation is as follows Figure 7 , Figure 8 shown.

[0039] Preferably, the upper flip movable member 11 and the lower flip movable member 12 have the same structure, the first ear-shaped linkage clamping member 21 and the second ear-shaped linkage clamping member 22 have the same structure, and the positions and angles of the same parts differ by 180 degrees. The upper flip movable member 11 and the lower flip movable member 12 are made of sheet metal, for example. This method makes production and processing easier and reduces costs.

[0040] To sum up, the utility model of the 180-degree flat-angle flip multi-purpose new hinge structure of the offset plate is mainly composed of an upper flip movable part and a lower flip movable part. A fixed rotating shaft part, a sliding rotating shaft part and a sliding displacement groove are designed in these two hardware parts. The positional relationship between the fixed axis and the sliding axis is utilized to realize the flipping movement and limiting of the upper flip movable part and the lower flip movable part through the ear-shaped linkage clamping parts based on physical principles; in addition, the offset fixed limiting structural design of the upper flip movable part and the lower flip movable part provides a position and conditions for installing relatively offset furniture panels, etc., thereby realizing the implementation of the relatively offset flip structure and achieving the complex functional requirements of the product; this scheme cancels the unstable application structure of the traditional spring, and can be widely used in multifunctional and versatile furniture, such as tables, chairs, library stairs and other versatile furniture products, effectively reducing the product cost, and making the product structure simpler to operate, easy to operate, and marketable.
