[0002] A flip work table, also called a flip table, generally refers to a table with a flip table top that can be flipped to adjust the angle. The table top can be flipped to be perpendicular to the ground, so that the table top can be folded up to reduce the space occupied by the table. In addition, when the table is packaged, transported or carried, the table top can also be folded up to save packaging and transportation space or to prevent the table top from being damaged by collision. Furthermore, the table top can be flipped to adjust the angle to tilt the desktop, so that the table can be used for painting, drawing and reading, etc. The flip work table of the related art is generally equipped with a locking structure, which can lock the table top after the table top is flipped to a certain angle.

[0012] In some embodiments, the driving handle is rotatably connected to the outer end of the positioning seat, and the driving handle can be rotated around the axis of the positioning seat, so that the driving handle can be rotated and switched between a first position and a second position, wherein, in the first position, the first locking structure of the connecting seat is locked with the second locking structure, and in the second position, the first locking structure of the connecting seat is disengaged and unlocked with the second locking structure.

[0013] In some embodiments, the outer end of the positioning seat is provided with a first recess and a first protrusion extending axially in sequence along the circumferential direction, and the first recess and the first protrusion have a smooth transition, and the driving handle is provided with a second protrusion matching with the first recess and a second recess matching with the first protrusion, when the driving handle is rotated to the first position, the second protrusion is abutted against the first protrusion, and when the driving handle is rotated to the second position, the second protrusion is matched in the first recess, and the first protrusion is matched in the second recess.

[0020] In addition, the cooperation of the two locking structures not only makes the locking of the table top more secure and stable after flipping, but also makes it very convenient to assemble. It only requires the connecting seat to be connected to the rotating shaft and to correspond to the positioning seat on the rotating shaft. It has low requirements on assembly precision and can greatly improve assembly efficiency.

[0021] Furthermore, the table top can slide on the rotating shaft together with the connecting seat. Especially when flipping the table top, the table top and the connecting seat are first slid to a position away from the positioning seat, and then slide in the opposite direction when locked. In this way, for a work table placed on the edge of a wall or against a wall, when flipping the table top, the table top can be slid away from the wall, which is more convenient to operate and avoids interference from the wall. When locking, the table top can be brought closer to the wall to fill the gap between the table top and the wall, thereby preventing items from falling and making reasonable use of the space.

[0042] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] See also Figures 1 to 8 , Fig.11 and Fig.12 As shown; the embodiment of the present application discloses a flip work table, which is also called a side table, a flip table, etc., and its structure includes a table top 1, table legs 2, and a rotating shaft 4 connected to the table legs 2. A connecting seat 5 is connected to the table top 1, and the connecting seat 5 is rotatably connected to the rotating shaft 4, so that the table top 1 can be flipped around the rotating shaft 4 to adjust the angle of the table top 1; moreover, the connecting seat 5 can slide along the axial direction of the rotating shaft 4, so that the table top 1 can slide synchronously with the connecting seat 5; that is, a center hole is provided on the connecting seat 5, and the center hole is sleeved on the rotating shaft 4, which can rotate relative to the rotating shaft 4 and can slide within a certain range along the axial direction of the rotating shaft 4. In this embodiment, the flip work table is a flip work table with a single table leg 2, so a base 3 is connected to the lower end of the table leg 2, and the table leg 2 is a liftable table leg 2, so that the height of the table top 1 relative to the base 3 can be adjusted; the rotating shaft 4 is connected to the upper end of the table leg 2, and the rotating shaft 4 is a cylindrical tube, in order to facilitate the circumferential rotation of the table top 1 around the rotating shaft 4. As shown Fig.11 and Fig.12 As shown, after the table top 1 is flipped over to a certain angle, it is locked and the table top 1 is in a tilted state.

[0044] In the above embodiment, the table leg 2 is a liftable table leg 2, for example, Figure 4 As shown, the table leg 2 includes an outer tube and an inner tube slidingly fitted in the outer tube, a gas spring 200 is provided in the inner tube, the upper end of the gas spring 200 is connected to the inner tube, the lower end of the gas spring 200 is connected to the bottom of the outer tube, the control valve of the gas spring 200 is provided at the upper end of the gas spring 200, and a rotary switch 201 is rotatably connected to the upper end of the inner tube, the rotary switch 201 is used to control the control valve of the gas spring 200, when the rotary switch 201 drives the control valve to open, the gas spring 200 unfolds the table leg 2 and rises, thereby realizing the height adjustment of the table top 1.

[0045] In other embodiments, the table leg 2 may also be an electrically liftable table leg 2, that is, a drive motor and a linear drive mechanism are provided in the table leg 2, and the drive motor drives the drive nut on the linear drive mechanism to move to adjust the height of the table leg 2. Similarly, in other embodiments, the table leg 2 may also be an ordinary non-liftable table leg 2.

[0046] In this embodiment, in order to lock the table top 1 with the rotating shaft 4 after being turned over, a locking structure is provided between the table top 1 and the rotating shaft 4, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the locking structure includes a first locking structure 503 connected to the connecting seat 5, at least one positioning seat 6 installed on the rotating shaft 4 and corresponding to the connecting seat 5, and a driving handle 7, and the positioning seat 6 is provided with a second locking structure 604 matched with the first locking structure 503 and locked at one end thereof close to the connecting seat 5; the driving handle 7 is connected to the connecting seat 5 and is located below the table top 1, and can drive the connecting seat 5 to slide. The connecting seat 5 and the table top 1 can move in the direction of approaching or moving away from the positioning seat 6 along the axial direction of the rotating shaft 4. Specifically, when the driving handle 7 drives the connecting seat 5 to approach the positioning seat 6, the first locking structure 503 on the connecting seat 5 can be locked with the second locking structure 604, so that the connecting seat 5 is in a locked state, the circumferential rotation of the connecting seat 5 is restricted, and the position of the table top 1 is locked; and when the connecting seat 5 is away from the positioning seat 6, the first locking structure 503 is disengaged from the second locking structure 604, so that the connecting seat 5 is in an unlocked state, and the connecting seat 5 can rotate circumferentially around the rotating shaft 4, so that the table top 1 can be flipped to adjust the angle. In this embodiment, the first locking structure 503 and the second locking structure 604 are coaxially arranged.

[0047] In this embodiment, the table top 1 of the flip work table is connected to the connecting seat 5, and can be rotated and flipped synchronously with the connecting seat 5. When flipping the table top 1, the connecting seat 5 or the table top 1 is axially moved along the rotating shaft 4, so that the first locking structure 503 on the connecting seat 5 is disengaged from the second locking structure 604 on the positioning seat 6. At this time, the table top 1 can be flipped to adjust the angle of the table top 1 or flip the table top 1 to a vertical folded state; when locking the table top 1, it is only necessary to drive the table top 1 and the connecting seat 5 to slide in the direction close to the positioning seat 6 until the first locking structure 503 and the second locking structure 604 are locked, so that the circumferential rotation of the connecting seat 5 is restricted, and the angle of the table top 1 relative to the rotating shaft 4 is fixed. Therefore, when the table top 1 is locked and unlocked, the flip work table of the present application only needs to move the table top 1 or the connecting seat 5, and its structure is simple, easy to operate and very labor-saving.

[0048] Furthermore, in the embodiment of the present application, the cooperation of the two locking structures can not only make the locking of the table top 1 after flipping more secure and stable, but also make the assembly very convenient. It only needs to put the connecting seat 5 on the rotating shaft 4 and correspond to the positioning seat 6 on the rotating shaft 4. It has low requirements on the assembly precision and can greatly improve the assembly efficiency.

[0049] It is not difficult to understand that the table top 1 can slide on the rotating shaft 4 along with the connecting seat 5, especially in the operation of flipping the table top 1, the table top 1 and the connecting seat 5 are first slid to a position away from the positioning seat 6, and then slid in the opposite direction when locked; in this way, for a work table placed on the edge of a wall or against a wall, when flipping the table top 1, the table top 1 can be slid away from the wall, which is more convenient to operate and avoids interference from the wall; when locking, the table top 1 can be brought closer to the wall to make up for the gap between the table top 1 and the wall, thereby preventing items from falling and making reasonable use of the space.

[0050] In this embodiment, the first locking structure 503 and the connecting seat 5 are an integrally formed structure, and the second locking structure 604 and the positioning seat 6 are an integrally formed structure, the connecting seat 5 and the table top 1 are connected by screws, and the positioning seat 6 and the rotating shaft 4 are also connected by screws. Therefore, its structure is simple and the assembly is very convenient.

[0051] In other embodiments, the first locking structure 503 may also be connected and fixed to the connecting seat 5 via fasteners. Similarly, the second locking structure 604 may also be connected and fixed to the positioning seat 6 via fasteners.

[0052] It is not difficult to understand that in this embodiment, since the table leg 2 is set as a single one, the table leg 2 is located on one side of the table top 1, and the table top 1 and the base 3 both extend to the side away from the table leg 2; therefore, the stability of the flip work table when standing and the stability of the table top 1 when flipping and adjusting the angle are important performance indicators of the flip work table. In order to make the table top 1 more stable and firm when locked, to prevent the table top 1 from shaking, and to consider the stability of the table top 1 in rotation and its high load-bearing capacity; in this embodiment, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the connecting seat 5 and the positioning seat 6 are both provided in pairs, and the two connecting seats 5 are respectively connected with a first locking structure 503, and the two positioning seats 6 are respectively connected with a second locking structure 604 matched and locked with the first locking structure 503. Because the two connecting seats 5 are both connected to the table top 1, when the table top 1 or any one of the connecting seats 5 is moved, the two connecting seats 5 can move synchronously.

[0053] When the driving handle 7 is released, in order to allow the first locking structure 503 of the connecting seat 5 and the second locking structure 604 of the positioning seat 6 to be quickly disengaged; Figure 4 , Figure 5 and Figure 6 As shown, an elastic member 8 is sleeved on the rotating shaft 4 between the first locking structure 503 and the second locking structure 604, and the two ends of the elastic member 8 are respectively against the first locking structure 503 and the second locking structure 604, and the elastic member 8 makes the first locking structure 503 always have a movement tendency away from the second locking structure 604. Further, in order to prevent the elastic member 8 from shifting when compressed or expanded, a first annular groove 502 coaxial with the first locking structure 503 is provided at one end of the first locking structure 503 close to the second locking structure 604, and a second annular groove 600 coaxial with the second locking structure 604 is provided at one end of the second locking structure 604 close to the first locking structure 503, and the two ends of the elastic member 8 are respectively clamped in the first annular groove 502 and the second annular groove 600.

[0054] In this embodiment, if Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the driving handle 7 can be rotatably connected to the outer end of the positioning seat 6, and the driving handle 7 can be rotated around the axis of the positioning seat 6, so that the driving handle 7 can be rotated and switched between the first position and the second position, wherein, in the first position, the first locking structure 503 of the connecting seat 5 is locked with the second locking structure 604, and in the second position, the first locking structure 503 of the connecting seat 5 is disengaged from the second locking structure 604. Specifically, the outer end of the positioning seat 6 is provided with a first recess 601 and a first protrusion 602 extending in the axial direction in sequence along the circumferential direction, and the first recess 601 and the first protrusion 602 are smoothly transitioned, and the driving handle 7 is provided with a second protrusion 700 matched with the first recess 601 and a second recess 701 matched with the first protrusion 602. When the driving handle 7 is rotated to the first position, the second protrusion 700 is against the first protrusion 602, and when the driving handle 7 is rotated to the second position, the second protrusion 700 is matched in the first recess 601, and the first protrusion 602 is matched in the second recess 701. When the driving handle 7 is rotated to the first position, the second protrusion 700 is abutted against the first protrusion 602, so that the driving handle 7 is axially away from the positioning seat 6 along the rotating shaft 4. When the driving handle 7 is rotated to the second position, the second protrusion 700 cooperates with the first recessed portion 601, and the driving handle 7 is axially close to the positioning seat 6 along the rotating shaft 4. Therefore, when the driving handle 7 is rotated from the second position to the first position, the first locking structure 503 of the connecting seat 5 can be driven to approach the second locking structure 604 of the positioning seat 6 and lock with it; conversely, the first locking structure 503 can be moved in a direction away from the second locking structure 604 and the two can be disengaged and unlocked.

[0055] Furthermore, in order to avoid misoperation or accidental rotation of the driving handle 7 in the locked state, an inwardly concave positioning groove 603 is provided in the center of the first convex portion 602 and the first concave portion 601, and an outwardly convex positioning block 702 is provided in the center of the second convex portion 700 and is adapted to be engaged with the positioning groove 603; therefore, when the driving handle 7 is in the first position, the positioning block 702 of the second convex portion 700 is engaged in the positioning groove 603 of the first convex portion 602, thereby avoiding accidental rotation of the driving handle 7 and causing unlocking.

[0056] In other embodiments, a convex positioning block may be provided at the center of the first convex portion 602 and the first concave portion 601 , and a concave positioning groove adapted to engage with the positioning block may be provided at the center of the second convex portion 700 .

[0057] In other embodiments, the driving handle 7 may also be a cam handle, which utilizes the cam structure to drive the connecting seat 5 to move and lock.

[0058] In this embodiment, the driving handle 7 is connected to the connecting seat 5 and drives the connecting seat 5 to move, which means that a pull rod 501 is connected inside the rotating shaft 4. Figure 4As shown, the pull rod 501 is connected to the positioning column 500 on any one of the connection seats 5 or is connected to the positioning columns 500 on both connection seats 5 at the same time, and the outer end of the pull rod 501 is connected to the driving handle 7. When the driving handle 7 is rotated to adjust the position, the pull rod 501 can drive the connection seat 5 to slide on the rotating shaft 4.

[0059] Furthermore, an elongated hole 400 is axially provided on the rotating shaft 4, and a positioning column 500 is gap-fitted in the elongated hole 400. A sliding seat 504 is slidably sleeved on the rotating shaft 4 on the side of the connecting seat 5 away from the driving handle 7. The sliding seat 504 is connected to the positioning column 500, and the sliding seat 504 is abutted against the connecting seat 5. Since the sliding seat 504 is circumferentially limited on the rotating shaft 4 by the positioning column 500, when the connecting seat 5 rotates with the table top 1, the connecting seat 5 and the sliding seat 504 can rotate relative to each other; a pull rod 501 is connected inside the rotating shaft 4, the pull rod 501 is connected to the positioning column 500, and the outer end of the pull rod 501 is connected to the driving handle 7. When the driving handle 7 is rotated from the second position to the first position, the pull rod 501 drives the positioning column 500 and the sliding seat 504 to slide along the length direction of the elongated hole 400 toward the positioning seat 6, and the sliding seat 504 drives the connecting seat 5 to slide synchronously; when the driving handle 7 is rotated from the first position to the second position, under the elastic force of the elastic member 8, the connecting seat 5 and the sliding seat 504 slide in the direction away from the positioning seat 6 and disengage and unlock from it.

[0060] In some embodiments, Fig. 9 and Fig.10 As shown, the driving handle 7 can also be a handle 9 rotatably connected to the positioning seat 6, and a buckling portion 900 is provided on the handle 9. When the first locking structure 503 of the connecting seat 5 is locked with the second locking structure 604 of the positioning seat 6, the buckling portion 900 can be rotated to buckle with the positioning seat 6 or the table top 1 to keep the connecting seat 5 in a locked state; when the buckling portion 900 of the handle 9 is disengaged from the positioning seat 6 or the table top 1, pulling the handle 9 can drive the connecting seat 5 to move in a direction away from the positioning seat 6 and disengage the first locking structure 503 from the second locking structure 604. In this embodiment, there is no need to set a pull rod in the rotating shaft 4. Of course, in order to limit the sliding stroke of the connecting seat 5 and make the connecting seat 5 rotate more smoothly relative to the rotating shaft, a guide hole 401 matching the connecting seat 5 is provided on the rotating shaft 4, and a guide column is connected to the connecting seat 5 with a clearance fit in the guide hole 401. The width of the guide hole 401 is much larger than the width of the elongated hole in the above-mentioned embodiment. The matching clearance between the guide hole 401 and the guide column can meet the requirement that the connecting seat 5 can not only slide on the rotating shaft 4, but also rotate around the rotating shaft 4.

[0061] In the embodiment of the present application, the locking between the first locking structure 503 and the second locking structure 604 is achieved by a tooth-engaging structure, such as Figure 5 and Figure 6As shown, the end surface of the first locking structure 503 is provided with teeth distributed in a circular shape, and the end surface of the second locking structure 604 close to the first locking structure 503 is provided with teeth engaged with the teeth of the first locking structure 503. When the teeth of the second locking structure 604 are engaged with the teeth of the first locking structure 503, the table top 1 is in a locked state, and when the teeth on the two locking structures are disengaged, the table top 1 is in an unlocked state.

[0062] In addition to the tooth-engagement locking, in other embodiments, the locking between the first locking structure 503 and the second locking structure 604 can also be achieved by a concave-convex snap-fit ​​structure, that is, the end face of the first locking structure 503 is provided with a plurality of protrusions or grooves distributed circumferentially, and the end face of the second locking structure 604 close to one end of the first locking structure 503 is provided with a groove or protrusion that matches the first locking structure 503 and snaps into place.

[0063] In other embodiments, Fig.13 and Fig.14 As shown, the locking between the first locking structure 503 and the second locking structure 604 can also be locked by a clutch member, that is, the first locking structure 503 and the second locking structure 604 are locked by a clutch plate 11, and the end faces of the two opposite ends of the first locking structure 503 and the second locking structure 604 are connected with an annular clutch plate 11, and the clutch plate 11 is an accessory of the prior art. When the clutch plate of the second locking structure 604 is pressed against the clutch plate of the first locking structure 503, the connecting seat or the table top is locked, and when the clutch plate of the second locking structure 604 is out of contact with the clutch plate of the first locking structure 503, the connecting seat or the table top is unlocked.

[0064] Likewise, in other embodiments, the locking between the first locking structure 503 and the second locking structure 604 may also be achieved by a friction structure, such as Fig.15 As shown, friction disks with rough friction surfaces are connected to the opposite end surfaces of the first locking structure 503 and the second locking structure 604. The friction surface can be a plurality of friction convex points or a rough surface with concave and convex alternatingly.
