Description

Technical Field

[0001] This utility model relates to the field of table technology, specifically to a mechanical flipping and adjusting mechanism and a table. Background Technology

[0002] Tables are used in all aspects of daily life, such as in kitchens, schools, and offices. As people's living standards improve, they have new requirements for the quality of home life, and tables have also evolved into various forms and functions. For example, there is a type of small table on the market that can be used to support small objects such as books, speakers, and lamps. Its overall structure is small, making it suitable for various scenarios and easy to move around.

[0003] However, the tabletops of existing storage tables on the market cannot be flipped or folded. This means that when the storage table is not in use, it occupies a large amount of space in both the horizontal and vertical directions, making it inconvenient for storage and resulting in low space utilization.

[0004] Therefore, in order to reduce the space occupied by the table when storing it, how to design a table with a tabletop that is easy to flip and fold has become the main problem that needs to be solved. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a mechanical flip adjustment mechanism and table, which locks or unlocks the rotating seat and the base through mechanical transmission, thereby controlling the tabletop unit to be fixed or movable relative to the table leg unit. The tabletop unit can be flipped and adjusted by simply turning the adjustment component, making the flip adjustment operation of the tabletop unit very convenient.

[0006] The effect of this utility model is achieved as follows:

[0007] In a first aspect, this application provides a mechanical flipping adjustment mechanism, including a rotating seat, a base, and a mechanical adjustment assembly. The rotating seat includes a vertically extending first connecting portion, and the base includes a vertically extending second connecting portion. The first and second connecting portions are hinged to each other, allowing the rotating seat to be flipped up and down relative to the base to adjust its angle. The mechanical adjustment assembly includes a rotating member and multiple locking slots. The rotating member is rotatably connected to the first connecting portion, and the multiple locking slots are formed in the second connecting portion. The rotating member is provided with a lock head that engages with the locking slot. The mechanical adjustment assembly also includes an adjustment member. The middle part of the adjustment member is hinged to the first connecting portion, and one end of the adjustment member is connected to the rotating member. When the adjustment member rotates relative to the first connecting portion, the rotating member is driven to rotate up and down synchronously, thereby causing the lock head to engage or disengage from the locking slot, thereby adjusting the relative fixation or movement of the rotating seat and the base.

[0008] Furthermore, the adjusting component has a bent L-shaped structure, including an adjusting part and a handle part that are inclined to each other. The intersection of the adjusting part and the handle part forms a rotating part, which is hinged to the first connecting part. The adjusting part is connected to the rotating component, and the handle part extends beyond the rotating seat in the horizontal direction. The handle part is configured to allow the user to rotate the adjusting component. When the adjusting part drives the rotating component to rotate inside the rotating seat, the handle part is always exposed outside the rotating seat and is not blocked by the rotating seat and the base, thus making the flip adjustment operation smoother.

[0009] Furthermore, a first groove is formed in the first connecting part, and a transmission pin is transversely inserted into the adjusting member. The transmission pin engages with the first groove and can slide along the first groove. The sliding engagement between the first groove and the transmission pin limits the range of motion of the adjusting member, further improving the stability of the mechanical tilting adjustment mechanism.

[0010] Furthermore, a transmission groove is hollowed out on the rotating component, and a transmission pin is transversely inserted into the adjusting component. The transmission pin engages with the transmission groove. When the transmission pin is driven by the rotating component to perform a circular motion, it slides along the transmission groove and presses against the groove wall, thereby forcing the rotating component to rotate up and down together. This creates a structure similar to a double-linkage and sliding groove between the rotating component, the adjusting component, and the transmission groove, making the adjustment operation of the mechanical flipping adjustment mechanism more stable and smooth.

[0011] Furthermore, both the rotating base and the base are U-shaped sheet metal parts. The left and right sides of the rotating base are bent to form a first connecting part, and the left and right sides of the second connecting part are bent to form a second connecting part. The first and second connecting parts on both sides are hinged to each other and kept in close contact. This makes the structure of the mechanical flip adjustment mechanism simpler, reduces manufacturing costs, and further improves the connection strength between the rotating base and the base, thereby improving the stability of the flip adjustment operation.

[0012] Furthermore, rotating parts are hinged to the outer sides of the first connecting parts on both sides, and adjusting parts are hinged between the first connecting parts on both sides. A transmission pin is transversely inserted through the adjusting part, with its left and right ends passing through the first connecting parts on both sides respectively, so that the rotating parts on both sides are connected to the transmission pin. Only one adjusting part is used to drive the rotating parts on both sides to rotate, thereby completing the locking and unlocking operation between the rotating seat and the base. This not only simplifies the structure but also makes the flipping and adjustment operation more convenient.

[0013] Furthermore, a baffle is provided between the first connecting parts on both sides, and the baffle is configured to cover the adjusting component. This ensures that during the adjustment process, no matter which angle the rotating seat is rotated to, the adjusting component inside the base will not be exposed, thus protecting the mechanical adjusting assembly.

[0014] Furthermore, the first connecting part and the rotating part are hinged together by a transverse pivot; the top of the baffle protrudes to form a vertical first locking part and a second locking part, both of which are hook-shaped structures, and the pivot is engaged between the first locking part and the second locking part, so that the baffle and the rotating seat remain relatively fixed in the horizontal direction. This not only makes the connection between the baffle and the base strong and stable, but also makes the installation and operation of the baffle simpler.

[0015] Furthermore, a rotation limiting structure is provided between the first connecting part and the second connecting part. The rotation limiting structure includes a second sliding groove and a limiting member. The second sliding groove is formed in one of the first connecting part and the second connecting part, and the limiting member is disposed in the other of the first connecting part and the second connecting part. When the rotating seat rotates relative to the base, the limiting member slides within the second sliding groove. The sliding cooperation between the limiting member and the second sliding groove restricts the range of motion of the rotating seat, further improving the stability of the mechanical tilting adjustment mechanism.

[0016] Secondly, this application provides a table, including a tabletop unit, table legs, and a mechanical flipping and adjusting mechanism. The tabletop unit is connected to the top of a rotating base, and the table legs are connected to the bottom of the base, so that when the rotating base flips relative to the base, the tabletop unit is driven to flip up and down relative to the table legs. This not only improves the practicality of the table, but also makes the flipping and adjusting operation of the tabletop unit very simple.

[0017] The mechanical flipping and adjusting mechanism and table provided in this application allow for easy flipping and adjusting of the table unit. Simply turn the adjusting component, causing the rotating component to rotate upwards, disengaging the lock from the locking groove. The rotating seat can then rotate relative to the base again. When the table unit is flipped to the desired position, simply release the adjusting component, causing it to rotate back, engaging the lock in the corresponding locking groove. The rotating seat and base then remain relatively fixed. Thus, by rotating the rotating component, the adjusting component engages or disengages the lock, locking or unlocking the rotating seat and base mechanically. This makes the flipping and adjusting of the table unit very convenient. Furthermore, during adjustment, the first and second connecting parts remain in contact and relatively fixed in the horizontal direction, resulting in good stability during the adjustment operation.

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0031] Please refer to the attached document. Figure 1-10This application provides a mechanical flipping adjustment mechanism, including a rotating seat 1, a base 2, and a mechanical adjustment assembly. The rotating seat 1 includes a vertically extending first connecting portion 110, and the base 2 includes a vertically extending second connecting portion 210. The first connecting portion 110 and the second connecting portion 210 are hinged to each other, so that the rotating seat 1 can be flipped up and down relative to the base 2 to adjust the angle. The mechanical adjustment assembly includes a rotating member 3 and a plurality of locking slots 211. The rotating member 3 is rotatably connected to the first connecting portion 110, and the plurality of locking slots 211 are formed in the second connecting portion 210. The rotating member 3 is provided with a lock head 310 that engages with the locking slot 211. The mechanical adjustment assembly also includes an adjustment member 4. The middle part of the adjustment member 4 is hinged to the first connecting portion 110, and one end of the adjustment member 4 is connected to the rotating member 3, so that when the adjustment member 4 rotates relative to the first connecting portion 110, the rotating member 3 is driven to rotate up and down synchronously, thereby causing the lock head 310 to engage or disengage from the locking slot 211, thereby adjusting the relative fixation or movement of the rotating seat 1 and the base 2.

[0032] In this embodiment, when it is necessary to flip and adjust the rotating seat 1, it is only necessary to turn the adjusting member 4, as shown in the attached figure. Figure 5-6 As shown, the adjusting member 4 drives the rotating member 3 to rotate upwards together, thereby causing the lock head 310 to disengage from the locking groove 211, and the rotating seat 1 can rotate relative to the base 2 again; when flipping the rotating seat 1 to the appropriate position, simply loosen the adjusting member 4, as shown in the attached diagram. Figure 6-7 As shown, the adjusting member 4 drives the rotating member 3 to rotate back together, and the locking head 310 engages with the corresponding locking groove 211, so that the rotating seat 1 and the base 2 remain relatively fixed. Thus, by the adjusting member 4 driving the rotating member 3 to rotate together, the locking head 310 is driven to engage or disengage from the locking groove 211, locking or unlocking the rotating seat 1 and the base 2 by mechanical transmission. This makes the adjustment operation of the mechanical flipping adjustment mechanism very simple, and during the adjustment process, the first connecting part 110 and the second connecting part 210 remain in contact with each other and are relatively fixed in the horizontal direction, which makes the stability of the adjustment operation better.

[0033] Preferably, the second connecting part 210 is detachably connected to a locking tooth 220. The top of the locking tooth 220 is recessed to form multiple tooth-shaped locking grooves 211, which are arranged in an arc shape. The bottom of the rotating part 3 protrudes to form multiple locking teeth-shaped lock heads 310. This not only makes the connection strength between the rotating seat 1 and the base 2 stronger when the lock head 310 is engaged with the locking groove 211, but also allows the mechanical adjustment assembly to have multiple adjustable positions, that is, the rotating seat 1 can be suspended at multiple tilt angles, with a high degree of adjustment freedom.

[0034] Please refer to the attached document. Figure 3-4In some embodiments of this application, the adjusting member 4 is a bent L-shaped structure, including an adjusting part 410 and a handle part 420 that are inclined to each other. The intersection of the adjusting part 410 and the handle part 420 forms a rotating part 430. The rotating part 430 is hinged to the first connecting part 110. The adjusting part 410 is connected to the rotating member 3. The handle part 420 extends beyond the rotating seat 1 in the horizontal direction. The handle part 420 is configured to allow the user to rotate the adjusting member 4.

[0035] In this embodiment, the rotating member 3 is located at the lower part of the first connecting part 110. If the adjusting member 4 is a straight rod, it may be blocked by the rotating seat 1 or the base 2 during the adjustment process, resulting in a less smooth adjustment operation. By setting the adjusting member 4 as a bent L-shaped structure, when the adjusting part 410 drives the rotating member 3 to rotate inside the rotating seat 1, the handle part 420 is always exposed outside the rotating seat 1 and is not blocked by the rotating seat 1 and the base 2, thereby making the flip adjustment operation smoother.

[0036] Please refer to the attached document. Figure 4 In some embodiments of this application, a first groove 111 is formed on the first connecting portion 110, and a transmission pin 440 is transversely inserted on the adjusting member 4. The transmission pin 440 is engaged with the first groove 111 and can slide along the first groove 111. The sliding cooperation between the first groove 111 and the transmission pin 440 limits the range of motion of the adjusting member 4, further improving the stability of the mechanical flipping adjustment mechanism.

[0037] Please refer to the attached document. Figure 3 In some embodiments of this application, a transmission groove 301 is formed on the rotating member 3, and a transmission pin 440 is transversely inserted on the adjusting member 4. The transmission pin 440 is engaged with the transmission groove 301. When the transmission pin 440 is driven by the rotating member 3 to perform circumferential motion, the transmission pin 440 slides along the transmission groove 301 and squeezes the groove wall, thereby forcing the rotating member 3 to rotate up and down together.

[0038] In this embodiment, the transmission pin 440 is engaged in the transmission groove 301, so that the rotating part 3, the adjusting part 4 and the transmission groove 301 form a structure similar to a double connecting rod and a sliding groove. That is, when the adjusting part 4 rotates, the transmission pin 440 slides in the transmission groove 301 and drives the rotating part 3 to rotate, making the adjustment operation of the mechanical flipping adjustment mechanism more stable and smooth.

[0039] Please refer to the attached document. Figure 3 In some embodiments of this application, the rotating seat 1 and the base 2 are both U-shaped sheet metal parts. The left and right sides of the rotating seat 1 are bent to form a first connecting part 110, and the left and right sides of the second connecting part 210 are bent to form a second connecting part 210. The first connecting part 110 and the second connecting part 210 on both sides are hinged to each other and kept in contact.

[0040] In this embodiment, both the rotating seat 1 and the base 2 are U-shaped sheet metal parts, which makes the structure of the mechanical flip adjustment mechanism simpler and the manufacturing cost lower. Furthermore, the first connecting part 110 and the second connecting part 210 on both sides remain in contact during the flip adjustment process, which further enhances the connection strength between the rotating seat 1 and the base 2, thereby further improving the stability of the flip adjustment operation.

[0041] The second connecting parts 210 on both the left and right sides are provided with horizontal side support parts 230. The side support parts 230 are configured to install extension components such as headphone brackets, cup holders, and power strips, thereby expanding the function of the mechanical flip adjustment mechanism, effectively utilizing the space under the table, and having good practicality.

[0042] Please refer to the attached document. Figure 3 In some embodiments of this application, rotating members 3 are hinged to the outer sides of the first connecting portions 110 on both sides, and adjusting members 4 are hinged between the first connecting portions 110 on both sides. A transmission pin 440 is transversely inserted through the adjusting member 4, with its left and right ends passing through the first connecting portions 110 on both sides, so that the rotating members 3 on both sides are connected to the transmission pin 440. By connecting the rotating members 3 on both sides with a single transmission pin 440, that is, by using only one adjusting member 4 to drive the rotating members 3 on both sides to rotate, the locking and unlocking operations between the rotating seat 1 and the base 2 are completed. This not only simplifies the structure but also makes the flipping and adjustment operation more convenient.

[0043] Please refer to the attached document. Figure 2-3 In some embodiments of this application, a baffle 120 is provided between the first connecting portions 110 on both sides, and the baffle 120 is configured to cover the adjusting member 4. This ensures that during the adjustment process, no matter which angle the rotating seat 1 is rotated to, the adjusting member 4 inside the base 2 will not be exposed, thereby protecting the mechanical adjusting assembly.

[0044] Please refer to the attached document. Figure 3 In some embodiments of this application, the first connecting part 110 and the rotating member 3 are hinged by a transverse pivot 130; the top of the baffle 120 protrudes to form a vertical first locking part 121 and a second locking part 122, both of which are hook-shaped structures, and the pivot 130 is engaged between the first locking part 121 and the second locking part 122, so that the baffle 120 and the rotating seat 1 remain relatively fixed in the horizontal direction.

[0045] In this embodiment, the baffle 120 clamps the rotating shaft 130 in the middle through the first snap-fit ​​part 121 and the second snap-fit ​​part 122. This not only makes the connection between the baffle 120 and the base 2 stronger and more stable, but also makes the installation of the baffle 120 simple. The first snap-fit ​​part 121 and the second snap-fit ​​part 122 of the baffle 120 only need to be aligned with the rotating shaft 130 and snapped in, or the baffle 120 and the moving seat 1 are spliced ​​together and then inserted into the rotating shaft 130 for series fixation. This makes the installation of the baffle 120 relatively simple.

[0046] Please refer to the attached document. Figure 1-2 In some embodiments of this application, a rotation limiting structure is provided between the first connecting portion 110 and the second connecting portion 210. The rotation limiting structure includes a second sliding groove 212 and a limiting member 140. The second sliding groove 212 is formed in one of the first connecting portion 110 and the second connecting portion 210, and the limiting member 140 is disposed in the other of the first connecting portion 110 and the second connecting portion 210. When the rotating seat 1 rotates relative to the base 2, the limiting member 140 slides within the second sliding groove 212. The sliding cooperation between the limiting member 140 and the second sliding groove 212 restricts the range of motion of the rotating seat 1, further improving the stability of the mechanical flipping adjustment mechanism.

[0047] Preferably, the limiting member 140 is a bolt, which is detachably connected to the first connecting portion 110, and the second connecting portion 210 is correspondingly hollowed out to form an arc-shaped second sliding groove 212. Of course, in other embodiments of this application, the limiting member 130 can also be provided on the second connecting portion 210, and the first connecting portion 110 can be hollowed out to form the second sliding groove 212.

[0048] Please refer to the attached document. Figure 8-10 This application embodiment also provides a table, including a tabletop unit 5, a table leg unit 6 and a mechanical flipping adjustment mechanism. The tabletop unit 5 is connected to the top of the rotating seat 1 and the table leg unit 6 is connected to the bottom of the base 2, so that when the rotating seat 1 flips relative to the base 2, the tabletop unit 5 is driven to flip up and down relative to the table leg unit 6.

[0049] In this embodiment, a mechanical flipping adjustment mechanism is provided between the tabletop unit 5 and the table leg unit 6, allowing the tabletop unit 5 to be flipped up and down relative to the table leg unit 6 to adjust its tilt angle. The tabletop unit 5 can not only be flipped to fit snugly against the table leg unit 6 to reduce its space occupation and facilitate storage, but it can also be flipped to tilt relative to the horizontal plane, making it easier for users to browse books and other objects on the table. This not only improves the practicality of the table, but also makes the flipping adjustment operation of the tabletop unit 5 very simple.

[0050] The mechanical switch 4 is located at the bottom of the tabletop unit 5, allowing the user to press the mechanical switch 4 with one hand while holding and flipping the tabletop unit 5 when flipping it, making the adjustment operation relatively simple.

[0051] Of course, in other embodiments of this application, the base 2 can be connected to the bottom of the tabletop unit 5, and the rotating seat 1 can be connected to the top of the table leg unit 6.
