Description

[Technical field]

[0001] The invention relates to the technical field of flip tables, and in particular to a self-locking flip table frame with high stability. [Background technology]

[0002] A table is a commonly used piece of furniture on which one can eat, work, put things, etc. A table consists of a desktop top and a table frame. The desktop top of a traditional table is fixed on the table frame, which is not convenient for storage. For people living in cities, housing prices are growing rapidly and living space is small. The table occupies a large space, making the entire room appear crowded and small.

[0003] In response to the above problems, foldable flip tables have appeared on the market. Their table frames are composed of crossed table legs, and the table top is hinged to one of the crossed table legs. When folding, the table legs are folded, the table top is flipped down and placed sideways next to the table legs. When in use, the table legs are crossed and unfolded, the table top is flipped upward and placed flat on the table frame. However, the table top of the flip table is easy to flap when folded, and the table legs are poor in stability. Generally, it needs to be leaned against a corner or the like. At the same time, there is a lack of fixing devices when in use, so it is easy to tip over and has poor stability. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and to design a self-locking flip table frame with simple structure and high stability.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A self-locking flip table frame with high stability comprises a crossbeam and a longitudinal beam rotatably connected to the crossbeam and capable of flipping relative to the crossbeam, the crossbeam is provided with a socket component, the socket component is provided with a receptacle, the flip table frame comprises a use mode and a storage mode, and the conversion between the use mode and the storage mode is achieved by flipping the longitudinal beam on the crossbeam, the longitudinal beam comprises an outer tube rotatably connected to the crossbeam and a locking piece arranged on the outer tube and capable of telescoping relative to the outer tube, when the flip table frame is in the use mode, the longitudinal beam is placed flat on the crossbeam, and the locking piece is inserted into the receptacle to lock the longitudinal beam.

[0007] The beneficial effects of adopting this solution:

By rotating the two fixed points of the connection point and the locking point, the longitudinal beam is firmly locked on the cross beam, and then the desktop panel is locked to avoid the desktop panel driving the longitudinal beam to be lifted when one side of the desktop panel is stressed during use, thereby improving the stability of the flip table frame. When storing after use, the locking piece is pulled out of the socket, and the storage operation is performed after the lock is released. The use mode and the storage mode are switched by flipping the longitudinal beam on the cross beam, which has strong functionality and convenient operation. The locking mechanism of the above-mentioned locking piece and the socket plug-in between the cross beam and the longitudinal beam has a simple structure, few parts, low difficulty in operation, low cost, and is easy to install and use.

[0009] Preferably, the locking piece is arranged in the outer tube, and the locking piece is axially retractable relative to the outer tube.

[0015] Preferably, the crossbeam is further provided with a connecting piece rotatably connected to the outer tube, and when the flip table frame is in the storage mode, the longitudinal beam side is placed beside the crossbeam side and locked.

[0016] Preferably, a notch is provided at the lower end of the connecting member, and the limiting member is elastically inserted into the notch to lock the longitudinal beam.

[0017] Preferably, a left longitudinal beam and a right longitudinal beam are respectively provided at both ends of the cross beam, a left drawer is provided on the left longitudinal beam, and a right drawer is provided on the right longitudinal beam. The left drawer and the right drawer are connected by a connecting rod to achieve synchronous flipping of the left and right longitudinal beams.

[0034] Example:

[0035] like Figures 1 to 8 As shown, a self-locking flip table frame with high stability includes a crossbeam 1 and a longitudinal beam 2 which is rotatably connected to the crossbeam 1 and can be flipped relative to the crossbeam 1, a socket 3 is provided on the crossbeam 1, and a socket 302a is provided on the socket 3. The flip table frame includes a use mode and a storage mode. The conversion of the use mode and the storage mode is achieved by flipping the longitudinal beam 2 on the crossbeam 1. The longitudinal beam 2 includes an outer tube 201 which is rotatably connected to the crossbeam 1 and a locking piece 202 which is provided on the outer tube 201 and can be telescoped relative to the outer tube 201. When the flip table frame is in the use mode, the longitudinal beam 2 is placed flat on the crossbeam 1, and the locking piece 202 is inserted into the socket 302a to lock the longitudinal beam 2.

[0036] The flip table uses the flip table frame of the present invention, and the desktop board is fixedly installed on the longitudinal beam 2. When in use, the outer tube 201 is manually flipped downward so that the locking piece 202 on the outer tube 201 is inserted into the socket 302a to realize the locking of the longitudinal beam 2 on the cross beam 1. By rotating the two fixed points of the connection point and the locking point, the longitudinal beam 2 is firmly locked on the cross beam 1, and then the desktop board is locked, so as to avoid the longitudinal beam 2 being lifted up by the desktop board when one side of the desktop board is subjected to force during use, thereby improving the stability of the flip table frame. When storing after use, the locking piece 202 is pulled out of the socket 302a, and the storage operation is performed after the lock is released. The use mode and the storage mode are switched by flipping the longitudinal beam 2 on the cross beam 1, which has strong functionality and convenient operation. The locking mechanism of the above-mentioned locking piece 202 and the socket 302a is used between the cross beam 1 and the longitudinal beam 2, which has a simple structure, few parts, low difficulty in operation, low cost, and is easy to install and use.

[0037] like Figure 3 to Figure 6 As shown, the front and rear ends of the locking member 202 are respectively provided with sliders 203, which slide in the outer tube 201. The sliders 203 prevent the locking member 202 from directly contacting the inner tube to reduce friction. The locking member 202 is preferably a telescopic block that slides in the outer tube 201.

[0038] like Figure 5 As shown, the socket 3 includes a fixing portion 301 fixed on the cross beam 1 and a socket portion 302 cooperating with the locking piece 202. The socket portion 302 protrudes from the upper surface of the cross beam 1 and is provided with a socket 302a. An opening is provided on the bottom wall of the outer tube 201 near the locking piece 202. In the use mode, the socket portion 302 is inserted into the outer tube 201 through the opening and cooperates with the locking piece 202.

[0039] In this embodiment, Figure 6 As shown, the locking member 202 is disposed in the outer tube 201. Figures 2 to 8As shown, the longitudinal beam 2 also includes a drawer 204, which is connected to the locking member 202 via a transmission rod 205. The drawer 204 drives the locking member 202 to extend and retract relative to the outer tube 201. The drawer 204 is disposed at one end of the outer tube 201 and at least partially extends out of the outer tube 201. The drawer 204 slides axially along the outer tube 201, and a pipe plug 206 is disposed at the other end of the outer tube 201.

[0040] like Figure 3 to Figure 5 As shown, a fixing block 207 is provided between the drawer 204 and the locking member 202. The fixing block 207 is fixed on the outer tube 201. The transmission rod 205 passes through the fixing block 207. In order to realize the automatic locking of the locking member 202, as shown in FIG. Figure 3 to Figure 6 As shown, an elastic return member 208, preferably a spring, is provided between the locking member 202 and the fixing block 207. The elastic return member 208 is sleeved on the transmission rod 205, and the transmission rod 205 guides the elastic return member 208. The two ends of the elastic return member 208 are respectively in contact with the locking member 202 and the fixing block 207. The elastic return member 208 is always in an extruded state, undergoes elastic deformation, and has a tendency to restore the elastic deformation, thereby giving the locking member 202 a forward thrust, so that the locking member 202 will not slide backwards from the socket 302a, thereby improving the stability of the flip table frame when in use.

[0041] Of course, the elastic reset member 208 may also be made of other elastic materials capable of realizing an automatic rebound function, such as elastic silicone, rubber, or a gas spring.

[0042] like Figure 5 and Figure 6 As shown, the front end of the locking piece 202 is provided with a downward inclined surface to form a first guide surface 202a. When in use, the longitudinal beam 2 is manually flipped downward and the outer tube 201 is pressed downward. The first guide surface 202a at the front end of the locking piece 202 slides downward and backward on the socket 3 and squeezes the elastic reset piece 208 until the front end of the first guide surface 202a also passes over the socket 3. The elastic reset piece 208 generates a forward thrust during the process of restoring the deformation and rebounding. The locking piece 202 is automatically inserted into the socket 302a under the action of the thrust to form a self-locking.

[0043] When storage is required, the drawer 204 is pulled backwards, and the drawer 204 pulls the locking member 202 through the transmission rod 205, and the locking member 202 moves toward the fixed block 207, squeezing the elastic reset member 208 until the locking member 202 is disengaged from the socket 302a. After releasing the drawer 204, the longitudinal beam 2 is flipped upwards.

[0044] Of course, in other embodiments of the present invention, a wrench or a pull wire may be used instead of the pull member 204 to pull the locking member 202 to achieve the unlocking function.

[0045] In order to achieve the above-mentioned automatic locking and control the backward pulling distance, the self-locking flip table frame with high stability also includes a limiting structure for limiting the telescopic stroke of the locking member 202.

[0046] In this embodiment, the limiting structure includes a limiting member 2021 provided on the side wall of the locking member 202 and a limiting hole 2011 provided on the outer tube 201. The limiting member 2021 slides in the limiting hole 2011. The limiting hole 2011 includes a first limiting end and a second limiting end away from the first limiting end. The first limiting end and the second limiting end limit the limiting member 2021. The first limiting end and the second limiting end are preferably the front hole wall and the rear hole wall of the limiting hole 2011. The limiting member 2021 is limited by the front hole wall, so as to limit the forward movement of the locking member 202, thereby preventing the locking member 202 from moving forward by itself. The forward sliding further improves the stability in the use mode, and at the same time controls the position of the first guide surface 202a of the locking piece 202. When it is close to the horizontal position, the rear end of the first guide surface 202a of the locking piece 202 can contact the socket 3, so that when the outer tube 201 is pressed downward, the locking piece 202 can smoothly slide into the socket 302a. Of course, the fixing block 207 can also be used to limit the pull-out piece 204 to limit the forward movement of the locking piece 202. In the best state, when the limiting piece 2021 reaches the front hole wall, the pull-out piece 204 just reaches the position of the fixing block 207.

[0047] In order to improve the stability during rotation, preferably, limiting members 2021 are provided at opposite positions on both sides of the locking member 202, and corresponding limiting holes 2011 are provided at positions corresponding to the limiting members 2021 on the side wall of the outer tube 201. The limiting member 2021 in this embodiment is preferably a pin shaft.

[0048] By limiting the position of the limiting member 2021 by the rear hole wall, the backward movement stroke of the locking member 202 is limited to prevent the limiting member 2021 from sliding backward under the action of gravity when flipping upward, thereby improving the stability during flipping and enhancing the user experience.

[0049] Of course, the first limiting end and the second limiting end may also be two limiting protrusions provided at both ends of the limiting hole 2011 .

[0050] In order to improve the stability of the self-locking flip table frame when it is stored, the crossbeam 1 is also provided with a connecting piece 4 rotatably connected to the outer tube 201. When the flip table frame is in the storage mode, Figure 7 and Figure 8As shown, the longitudinal beam 2 is placed beside the transverse beam 1 and locked, a notch 401 is provided at the lower end of the connecting member 4, and the limiting member 2021 is elastically inserted into the notch 401 to lock the longitudinal beam 2. Specifically, the notch 401 opens downward, and the side wall of the notch 401 forms a stopper 402 to prevent the limiting member 2021 from escaping from the notch 401. A second guide surface 402a obliquely facing inward is provided at the stopper 402. The limiting member 2021 is limited by the second limiting end to control the position of the limiting member 2021, so that when the longitudinal beam 2 approaches the side of the cross beam 1, the limiting member 2021 approaches the upper end of the second guide surface 402a. When the outer tube 201 is pressed laterally, the limiting member 2021 moves downward and forward on the second guide surface 402a and squeezes the elastic reset member 208. After passing the apex of the stopper 402, the elastic reset member 208 is elastically snapped into the notch 401 under the rebound action of the recovery deformation of the elastic reset member 208 to achieve locking during storage, thereby improving the stability of the entire self-locking flip table frame with high stability during storage.

[0051] The flip table with a highly stable self-locking flip table frame in this embodiment can be used in application scenarios such as conference blackboard writing and upright painting after being locked in the storage mode.

[0052] In order to enable the longitudinal beam 2 to be flipped to lie flat on the cross beam 1, in this embodiment, the upper end of the connecting piece 4 is provided with a connecting ear 403 protruding from the upper surface of the cross beam 1, and the outer tube 201 is rotatably connected to the connecting ear 403 via a rotating shaft 5. The rotating shaft 5 passes through the outer tube 201 and the locking piece 202 in sequence. The locking piece 202 is provided with a slide groove 2022. The rotating shaft 5 slides in the slide groove 2022. The slide groove 2022 includes a third limit end and a fourth limit end. The third limit end and the fourth limit end limit the rotating shaft 5.

[0053] The third limiting end and the fourth limiting end are preferably the rear groove wall and the front groove wall of the slide groove 2022. The rear groove wall limits the rotation shaft 5 to limit the forward movement stroke of the locking member 202; the front groove wall limits the rotation shaft 5 to limit the backward movement stroke of the locking member 202.

[0054] Of course, the third limiting end and the fourth limiting end may also be two limiting protrusions provided at both ends of the slide groove 2022 .

[0055] In order to improve the stability of connection and rotation, preferably, the outer tube 201 has shafts 5 at opposite positions on the inner sides of both side walls, and the locking member 202 has corresponding slide grooves 2022 at positions corresponding to the shafts 5 on the side walls.

[0056] The limiting member 2021 and the limiting hole 2011 form a first limiting structure, and the slide groove 2022 and the rotating shaft 5 form a second limiting structure. Through the double limiting structure, better limiting is formed for the telescopic device locked in the outer tube 201, thereby improving stability during use and operation.

[0057] In order to make the flip table with high stability and self-locking flip table frame more stable when in use, flipping and storage, Figure 1 , Figure 3 and Figure 7 As shown, longitudinal beams 2 are respectively provided at the left and right ends of the crossbeam 1, and drawer pieces 204 are respectively provided on the longitudinal beams 2 at both ends. The two drawer pieces 204 are connected by a connecting rod 6 to realize synchronous flipping of the two longitudinal beams 2, thereby driving the two ends of the desktop panel fixed on the longitudinal beams 2 to flip synchronously.

[0058] In order to improve the functionality of the highly stable self-locking flip table frame, a lifting column 7 serving as a table leg 8 is further provided under the crossbeam 1 in this embodiment. Preferably, there are two lifting columns 7, which are respectively located at the two ends of the crossbeam 1. The lifting columns 7 are adjusted by a motor-controlled mechanical device to adjust the height of the highly stable self-locking flip table frame to suit people of different heights and to satisfy the conversion between sitting and standing office work.

[0059] Table legs 8 are provided below the lifting columns 7, and the table legs 8 ensure the overall stability of the lifting table frame.

[0060] The above embodiments are only examples and do not limit the scope of the present invention. Based on this, those skilled in the art can foresee other implementations that can achieve the same function within the scope of the claims of the present invention.

[0061] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
