[0043] The present invention will be further described below with reference to the accompanying drawings.

[0044] Reference Figure 1 The flip table includes a table top 100, a support member, and a flip mechanism. The bottom of the support member is fixed to the left or / right side of the seat, the backrest side of the seat is the rear, the side away from the backrest is the front, and the armrests on both sides of the seat are the left and right directions. The flip mechanism is set at the top of the support member, and the table top 100 is connected to the flip mechanism.

[0045] Reference Figure 2 The flip mechanism includes a base 200 and a flip seat 230 movable on the base 200. The flip seat 230 is provided with a fixed central axis 210. Ear plates 201 are provided on the front and rear sides of the upper part of the base 200. The ear plates 201 are provided with through holes running through the front and rear. The central axis 210 is passed through the through holes. The central axis 210 is movably matched with the through holes. The flip seat 230 has the ability to move forward and backward along the axial direction of the central axis 210 relative to the base 200, and the ability to flip up and down with the central axis 210 as the movable axis.

[0046] A connecting block 220 is sleeved on the central axis 210, and the connecting block 220 is fixed to the central axis 210 by a positioning screw that radially penetrates the central axis 210. The flip seat 230 is provided with a downwardly extending side panel 223 near the inner side of the seat. As a preferred embodiment, the side panel 223 is perpendicular to the horizontal plane. The flip seat 230 can adopt an L-shaped metal angle iron, and the side panel 223 is one side of the angle iron. The front end of the positioning screw extends to the side panel 223 and is connected to the side panel 223. The flip seat 230, the central axis 210, and the connecting block 220 are connected as one, and the movement state remains consistent. The flip plate 203 is fixedly connected to the bottom end surface of the inner side of the seat of the table board 100. The table board 100 is connected as one with the flip seat 230, the central axis 210, and the connecting block 220. A lower connecting plate 202 is provided at the bottom of the base 200, and the lower connecting plate 202 is connected to the top of the support member.

[0047] The bottom end surface of the connecting block 220 is a first locking surface 221. A locking block 240 is provided on the bottom side of the central axis 210 on the base 200. The upper surface of the locking block 240 is a second locking surface 241 that cooperates with the first locking surface 221. As a preferred embodiment, the first locking surface 221 and the second locking surface 241 are both inclined surfaces. Along the axial direction of the central axis 210, the front side height of the first locking surface 221 is higher than the rear side height thereof. The first locking surface 221 fits in with the second locking surface 241. Due to the locking The block 240 is fixed, and the second locking surface 241 limits the rotation of the first locking surface 221, and then locks the axial rotation of the central axis 210 to limit the flipping movement of the table top 100. The central axis 210 has the ability to move forward and backward. When the central axis 210 moves backward, the first locking surface 221 disengages from the second locking surface 241, and the rotation ability of the central axis 210 is restored. The table top 100 can be flipped up and down. The central axis 210, the locking block 240, and the connecting block 220 form a clutch mechanism for controlling the up and down flipping movement of the table top 100.

[0048] In one embodiment, the first locking surface 221 is in contact with the second locking surface 241 , and the locking block 240 prevents the central axis 210 from rotating, thereby maintaining the table top 100 in an open state.

[0049] A spring 250 is sleeved on the central axis 210 to keep the central axis 210 always moving forward. In one embodiment, the spring 250 is sleeved on the shaft body of the central axis 210 on the front side of the base 200. The rear end of the spring 201 abuts against the front side surface of the front ear plate 201, and the front end of the spring 201 abuts against the retaining spring set on the front shaft body of the central axis 210. The spring 250 is in a compressed state. The spring 250 has a forward force on the central axis 210, so that the central axis 210 always keeps moving forward. When the table top 100 is in the open state, the table top 100 is in a horizontal state. The elastic force of the spring 250 keeps the central axis 210 and the connecting block 203 moving forward. The first locking surface 221 and the second locking surface 241 remain in contact and locked, and the open state of the table top 100 remains stable.

[0050] The table top 100 flips and closes: push the table top 100 backward, the table top 100 drives the central axis 210 and the connecting block 220 to move backward synchronously, and the first locking surface 2031 disengages from the second locking surface 2041. When the first locking surface 2031 is completely disengaged from the second locking surface 2041, the central axis 210 resumes its rotation ability. Since the flip seat 230 is connected to the inner side of the table top 100, under the weight of the table top 100, the table top 100 automatically flips downward with the central axis 210 as the flip axis and folds to the side of the seat to complete the closing of the table top 100. The closing operation is simple and quick, which is convenient for people sitting on the seat to use. The use effect of the table top 100 is significantly enhanced compared with the existing technology.

[0051] Table top 100 opening operation: The table top 100 flips upward from the bottom. When the table top 100 is opened to a horizontal state, under the action of the spring 250, the spring pushes the connecting block 220, the central axis 210, and the table top 100 forward, and the first locking surface 2031 fits with the second locking surface 2041 to achieve locking, and the table top 100 is in a horizontally opened state.

[0052] The table top 100 features simple opening and closing operations, a fast response speed, and a sophisticated flip mechanism, significantly improving the usability of the flip table top. Compared to existing technologies, the flip table top has a fast closing response speed, fully utilizes the structural design to achieve table top movement, and achieves an organic combination of table top movement and structure. The simple and quick operation improves the practicality of the table top, and has the advantages of low cost and high usability.

[0053] During the opening process of the table top 100, the flip seat 230 flips upward synchronously. When the table top 100 flips to a horizontal state, the side panel 223 changes from a horizontal state to a vertical state, and the bottom of the side panel 223 contacts the bottom of the base 200 to form a limit when opening. When limited at this position, the first locking surface 221 and the second locking surface 241 are exactly parallel. Under the push of the spring 250, they fit together smoothly, and the table top 100 opens horizontally, effectively ensuring the smoothness of the opening process.

[0054] A limit plate 260 is provided on the side of the bottom of the flip seat 230 away from the side panel. The distance between the limit plate 260 and the side panel 223 is consistent with the width of the ear plate 201. After the table top 100 is opened horizontally, that is, after the first locking surface 221 and the second locking surface 241 are fitted together, the limit plate 260 just moves to the outside of the ear plate 201, forming a downward limit for the table top 100, which significantly enhances the load-bearing capacity of the table top 100. After the table top 100 is opened, it is more reliable and stable to place items.

[0055] The upper inner part of the limit plate 260 is provided with a limit arm 261 extending toward the side of the side panel 223. After the table panel 100 is opened horizontally, the limit arm 261 just moves the limit plate 9 to the top of the ear plate 201. To facilitate the flipping of the flip seat 230, the top of the ear plate 201 is an arc surface, and the limit arm 261 and the limit plate 260 are transitioned by an arc surface. The limit arm 261 is stuck between the upper side of the ear plate 201 and the bottom end surface of the flip seat 230. The arc surface transition cooperates with the arc surface structure of the ear plate 201, forming an upward limit for the table panel 100. When the table panel 100 is flipped to open horizontally, the arc surface transition at the limit arm 261 and the top of the ear plate 201 form a limit, which can limit the table panel 100 from continuing to flip up, thereby ensuring that the connecting block 220 and the locking block 240 can be smoothly locked.

[0056] In one embodiment, referring to Figure 3A convex positioning block 222 is provided on the top of the connecting block 220, and a positioning hole 231 is provided at the corresponding position on the flip seat 230. The positioning block 222 is embedded in the positioning hole 231. Preferably, an interference fit is adopted between the positioning block 222 and the positioning hole 231. The connecting block 220 is fixed on the flip seat 230, thereby enhancing the connectivity between the connecting block 220 and the flip seat 230 and realizing the synchronization of the movement state. A table top positioning hole 110 can also be provided at the corresponding position of the table top 100, and the connecting block 220 can extend into the table top positioning hole 110 to improve the installation accuracy of the table top 100 and at the same time improve the reliability of the fixation of the table top 100.

[0057] Reference Figure 4 The top of the limiting plate 260 is provided with an engaging block 262. The flip seat 230 is provided with an engaging hole 232 that mates with the engaging block 262. The table top 100 is provided with a corresponding table top connecting hole 120 that mates with the engaging block 262. After the engaging block 29 is engaged with the engaging hole 232, it continues to engage upward into the table top connecting hole 120. An interference fit is achieved between the engaging block 262, the engaging hole 232, and the table top connecting hole 120, thereby achieving the connection between the table top 100 and the flip seat 230. To strengthen the connection, welding is also used between the flip seat 230, the table top 100, and the limiting plate 260.

[0058] Reference Figure 5 The table top 100 includes a metal base plate 130 and a decorative plate 140 on the upper surface of the metal base plate 130. The table top connecting holes 120 and the table top positioning holes 110 are opened on the metal base plate 130. The decorative plate 140 and the metal base plate 130 can be connected by gluing.

[0059] In one embodiment, referring to Figure 2 The bottom of the locking block 240 is provided with a bottom plate 242, and the bottom plate 242 is provided with a downward-opening clamping groove. The bottom plate 242 is connected to the base 200 through the clamping groove. The clamping groove is provided with an inwardly convex claw at the notch of the clamping groove to loosen the surface. Further, the bottom plate 242 is fastened to the base 200 by screws. The locking block 240 and the bottom plate 242 are an integrated structure, which is convenient for rapid assembly and production.

[0060] In one embodiment, referring to Figure 6The connecting block 220 includes a connecting portion 223 and a locking portion 224. The connecting portion 223 and the locking portion 224 are an integrated structure. The connecting portion 223 is used to cooperate with the central axis 210. A through hole that cooperates with the central axis 210 is provided at the center of the connecting portion 223. The through hole extends to the locking portion 224. The locking portion 224 cooperates with the axis of the central axis 210 to increase the contact area between the central axis 210 and the connecting block 220, thereby improving the stability and reliability of the connection between the central axis 210 and the connecting block 204. The positioning screw is inserted from one side of the connecting portion 223, penetrates the central axis 210, and then comes out from the other side, and then screwed into the side plate 223 to realize the connection block. 220 is effectively fixedly connected to the central axis 210, the locking portion 224 is located in front of the connecting portion 223, the bottom surface of the connecting portion 223 is lower than the bottom surface of the locking portion 224, and the junction of the connecting portion 223 and the locking portion 224 is a stepped limiting surface 225. When the central axis 210 and the connecting block 220 move forward, the limiting surface 225 contacts the rear side surface of the locking block 240, and the locking block 240 restricts the connecting block 220 from continuing to move forward. The first locking surface 221 is located at the bottom surface of the locking portion 224. When the limiting surface 245 contacts the rear side surface of the locking block 240, the first locking surface 221 and the second locking surface 241 are completely fitted together, and the table top 100 is locked in an open state.
