Description

Technical Field

[0001] The utility model relates to the field of office and household products, in particular to a flip table. Background Art

[0002] Office desks are a commonly used item at present. In order to be able to store them together when not in use, more and more office desks are now designed with flippable table tops. Patent announcement document CN203399802U discloses an office desk with a flippable table top. However, there is a problem with this type of office desk during actual use, that is, when the table top of a table with this structure is in a horizontal state (that is, when the engaging groove and the engaging piece are engaged together), the entire table top is in a fixed state, and when the engaging groove and the engaging piece are not engaged together (that is, the table top is in a vertical state), the table top is in a state where it can shake freely, and the free shaking of the table top will inevitably cause damage to the table top. Utility Model Content

[0003] In view of the above problems, the utility model provides a flip table.

[0004] The technical solution adopted by the utility model is as follows:

[0005] The two ends of the lever are connected with the support frame, and the two ends of the lever are connected with the support frame by the spring, and the two ends of the lever are connected with the support frame by the spring.

[0006] When the first supporting surface is in close contact with the first contact surface, and the second engaging hook is engaged with the second engaging groove, the table top is in a state perpendicular to the supporting legs (i.e., the table top is parallel to the ground);

[0007] When the first locking angle surface (the first locking angle surface is composed of two planes, and the angle between the two planes of the first locking angle surface is 90 degrees) is in close contact with the first locking surface and the first contact surface, the table top is in a state parallel to the support leg (that is, the table top is perpendicular to the ground).

[0008] In the flip table, a support is installed on each leg, and a sliding support plate is installed on each support through a pin shaft. A pull rod is installed on each sliding plate through a spring elastic limiter, so there are two pull rods in total for the flip table. The two ends of the handle are respectively matched with the two pull rods. By dragging the handle, the pull rod can be pulled to move on the sliding support. The movement of the handle on the sliding frame will cause the first card surface, the first contact surface and the second card groove on the pull rod to change the coordination with the first card block and the second card block.

[0009] First, when the first supporting surface is in close contact with the first contact surface, and the second engaging hook is engaged with the second slot, the sliding plate is perpendicular to the supporting foot, and the table top on the sliding plate is parallel to the ground. If the table top needs to be flipped at this time, the handle is manually pulled, and the handle drives the pull rod to move on the sliding plate. After the pull rod moves, the second engaging hook no longer engages the second slot, and the first contact surface is also out of contact with the first supporting surface. At this time, under the action of the table top's own weight, the table top (with the sliding plate and the pull rod) rotates together, and the axis of rotation is the pin. When the first engaging surface and the first contact surface are in close contact with the first engaging angle surface, the table top is perpendicular to the ground. At this time, the handle is released, and under the action of the spring, the first engaging surface and the first contact surface are in close contact with the first engaging angle surface. At this time, the sliding plate is in an elastic locking state, and the sliding plate cannot deviate, and the table top cannot deviate. When the table top needs to be flipped from perpendicular to the ground to parallel to the ground, continue to pull the handle, and the handle pulls the pull rod to move on the slide plate, so that the first card surface and the first contact surface on the pull rod are out of contact with the first card angle surface. At this time, the user can flip the table top, so that the table top is rotated again until the first supporting surface is close to the first contact surface, and the second card hook is engaged with the second card slot. Due to the elastic force of the spring, the table top is always in a locked state (i.e., it cannot shake) regardless of whether it is perpendicular to the ground or parallel to the ground. During the above rotation of the table top, the first card block needs to enter and exit the slide plate through the first through hole, and the second card block needs to enter and exit the slide plate through the second through hole.

[0010] Therefore, in the flip table, the table top is in a locked state in both states. When the table top is locked, it cannot shake, which reduces the probability of the table top being damaged.

[0011] In the specific flip table, a connecting piece is provided on the slide tray, and the table top is fixed together with the connecting piece by bolts or screws, and there are no less than 2 connecting pieces on the same slide tray, and the connecting pieces on the same slide tray are in a parallel state.

[0012] Optionally, a first arc transition surface is provided on the first engaging block, and the two ends of the first arc transition surface are respectively connected to the first engaging angle surface and the first supporting surface; a second guide clamping inclined surface is provided on the second engaging block, and a second guide inclined surface is provided at the second engaging groove of the pull rod, and the second guide clamping inclined surface is used to contact the second guide inclined surface.

[0013] Since the first engaging surface and the first contact surface on the pull rod may come into contact with the first engaging block during the rotation of the table top, a first arc transition surface is provided on the first engaging block. The first arc transition surface is used to contact the first engaging angle surface and the first supporting surface. This can minimize the wear of the first engaging block and the pull rod and reduce the resistance encountered when the table top rotates.

[0014] A second guide clip bevel is provided on the second engaging block (the second guide clip bevel is located on one side of the second engaging hook), and a second guide bevel is provided at the second engaging slot of the pull rod. The second guide clip bevel is used to contact the second guide bevel. This is to ensure that the second engaging hook slides into the second engaging slot more smoothly and reduce the resistance encountered when the second engaging hook engages with the second engaging slot.

[0015] Optionally, an extension rod is also included, the pull rod is provided with a plurality of inserts and a plurality of embedding grooves, the extension rod is provided with a plurality of holes and a plurality of embedding hooks, some of the inserts on the pull rod cooperate with some of the holes on the extension rod, some of the embedding grooves on the pull rod cooperate with some of the embedding hooks on the extension rod, and the handle is plugged and cooperated with the extension rod.

[0016] Specifically, the inserts on the pull rod are square inserts, and there are two rows of inserts on the pull rod, and the distance between two adjacent inserts in each row is equal, and the two rows of inserts are in a parallel state. The sockets on the extension rod are square sockets, and the two rows of sockets on the extension rod are in a parallel state, and the distance between two adjacent sockets in each row of sockets on the extension rod is equal. Some inserts on the pull rod cooperate with some sockets on the extension rod, and some embedded grooves on the pull rod cooperate with some embedded hooks on the extension rod, which is equivalent to the pull rod and the extension rod forming a rod together. The length of the rod can be adjusted appropriately as needed, so that the relative distance between the handle and the beam can be adjusted. Since the distance between the handle and the beam can be adjusted appropriately according to usage requirements, the sliding plate can adapt to the installation of table tops of different widths.

[0017] Optionally, the slide plate is a flat-bottomed U-shaped slide plate, a limiting slide column is arranged on the slide plate, a limiting slide hole is arranged on the pull rod or the extension rod, and the limiting slide column is located in the limiting slide hole.

[0018] Specifically, it also includes an auxiliary plate, which is installed on the sliding plate by screws. The auxiliary plate and the sliding plate form a clamping space similar to the shape of a U.S. character. The pull rod (and the extension rod) slide in the clamping space similar to the U.S. character. This can further improve the stability of the pull rod when sliding. The limiting sliding column is opened on the auxiliary plate, and the limiting sliding column is perpendicular to the auxiliary plate, the pull rod and the extension rod.

[0019] The flat-bottomed U-shaped slide tray allows the pull rod (and the extension rod) to slide stably on the ground inside the slide tray, because the flat-bottomed U-shaped slide tray itself is equivalent to a slide groove.

[0020] The function of the above-mentioned limit sliding hole and limit sliding column is to limit the sliding amount of the pull rod (and the extension rod) on the sliding tray. When the limit sliding column is close to the limit position of the limit sliding hole, the pull rod will not be able to continue to slide on the sliding tray.

[0021] Specifically, the limit sliding column is a cylindrical limit sliding column, and the limit sliding hole is a waist-shaped limit sliding hole.

[0022] Optionally, a plug-in square hole is provided on the support, the crossbeam is a square tubular crossbeam, the crossbeam and the plug-in square hole are matched together, and the support and the crossbeam are fixed together by a bolt assembly.

[0023] Specifically, the square tube-shaped crossbeam is inserted into the inserting square hole, and the crossbeam and the support are fixed together by a bolt assembly, and can be disassembled and assembled as needed.

[0024] At the same time, in order to facilitate the rapid assembly of the crossbeam on the support, two side pieces can be set on the support, the two side pieces are located at the openings of the plug-in square holes, the two side pieces are in a parallel state, and the two side pieces are respectively pressed against the crossbeam from both sides.

[0025] Optionally, it also includes a covering cover, the supporting foot is a hollow square tubular supporting foot, the supporting base is inserted into the supporting foot, a side hole is opened on the supporting base, the covering cover is arranged on the supporting base, and the elastic hook on the covering cover cooperates with the side hole.

[0026] The specific function of the covering cover is to cover the support. Since the covering cover is matched with the side holes on the support through its own elastic hooks, the covering cover can be removed from the support as needed.

[0027] Optionally, the crossbeam includes an inner crossbeam and an outer crossbeam, both of which are in the shape of hollow square tubes, the inner crossbeam consists of two, the two inner crossbeams are respectively sleeved on the two ends of the outer crossbeam, and the two inner crossbeams are respectively cooperated with the two supports; the handle includes an inner hand rod and an outer hand rod, both of which are in the shape of hollow tubes, the inner hand rod has two, the two inner hand rods are respectively sleeved on the two ends of the outer hand rod, and the inner hand rod is used to indirectly cooperate with the support.

[0028] Specifically, the two inner crossbeams are respectively connected to the two ends of the outer crossbeam, and the inner crossbeam and the outer crossbeam are fixed together by screws or bolts, which is equivalent to that the length of the entire crossbeam can be adjusted according to the use needs. In order to adapt to the adjustable design of the above crossbeam length, the two inner hand rods are respectively connected to the two ends of the outer hand rod, and the inner hand rod and the outer hand rod are fixed together by screws or bolts. The inner hand rod and the outer hand rod together form a handle with adjustable length. The inner hand rod is plugged and fixed with the extension rod on the pull rod. Since the length of the crossbeam and the handle can be adjusted according to needs, the table board used for the entire table can also be selected according to needs.

[0029] Specifically, the inner cross beam is inserted into the inserting square hole of the support and is fixed on the support through a bolt assembly.

[0030] Optionally, a stabilizing frame is provided on the supporting leg, and wheels are installed on the stabilizing frame.

[0031] Optionally, the spring is located between the sliding plate and the pull rod, and the spring is parallel to the sliding plate and the pull rod, one end of the spring directly or indirectly presses against the sliding plate, and the other end of the spring directly or indirectly presses against the pull rod.

[0032] Specifically, one end of the spring is against the auxiliary plate on the sliding plate, and the spring is parallel to the sliding plate and the auxiliary plate. The other end of the spring is against the pull rod. In order to improve the installation stability of the spring, contacts are provided on the auxiliary plate and the pull rod. The two ends of the spring are respectively embedded in the contacts of the auxiliary plate and the pull rod to ensure that the spring will not detach during the extension and retraction process.

[0033] Optionally, the handle is parallel to the crossbeam, and the handle and the crossbeam are perpendicular to the supporting legs.

[0034] The beneficial effect of the utility model is that the table top is in a locked state in both states, and the table top cannot shake when locked, thereby reducing the probability of the table top being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The utility model is described in detail below in conjunction with the accompanying drawings.

[0044] As attached Figure 1 , 2, 3, 4, 5, 6 and 7, a flip table includes a leg 2, a beam and a support 7, there are two legs 2, each leg 2 is provided with a support 7, the two ends of the beam are respectively matched with the supports 7 on the two legs 2, and also includes a slide plate 1, a pull rod 14, a spring 17 and a handle, the support 7 is provided with a first clamping block 701 and a second clamping block 702, the first clamping block 701 is provided with a pin shaft, the slide plate 1 is rotatably mounted on the pin shaft, and the pull rod 14 is slidably elastically mounted on the slide plate 1 through the spring 17; the two ends of the handle The ends are respectively matched with two pull rods 14, the first engaging block 701 is provided with a first engaging angle surface 7012 and a first supporting surface 7011, the second engaging block 702 is provided with a second engaging hook 7021, the pull rod 14 is provided with a first contact surface 1405 and a first card surface 1406, the first contact surface 1405 and the first card surface 1406 are in a vertical state, and the pull rod 14 is provided with a second card slot 1403; the slide plate 1 is detachably provided with a table top; the slide plate 1 is provided with a first through hole and a second through hole;

[0045] When the first supporting surface 7011 is close to the first contact surface 1405, and the second engaging hook 7021 is engaged with the second engaging groove 1403, the table top is in a state perpendicular to the supporting leg 2 (ie, the table top is parallel to the ground);

[0046] When the first snap-fitting angle surface 7012 (the first snap-fitting angle surface 7012 is composed of two planes, and the angle between the two planes of the first snap-fitting angle surface 7012 is 90 degrees) is in close contact with the first snap-fitting surface 1406 and the first contact surface 1405, the table top is in a state parallel to the support leg 2 (that is, the table top is perpendicular to the ground).

[0047] In the flip table, a support 7 is installed on each leg 2, and a sliding support plate 1 is installed on each support 7 through a pin shaft. Each sliding plate is installed with a pull rod 14 through a spring 17 for elastic limitation. Therefore, there are two pull rods 14 in total on the flip table. The two ends of the handle are respectively matched with the two pull rods 14. By dragging the handle, the pull rod 14 can be pulled to move on the sliding support. The movement of the handle on the sliding frame will cause the first card surface 1406, the first contact surface 1405 and the second card groove 1403 on the pull rod 14 to change the coordination with the first card block 701 and the second card block 702.

[0048] First, when the first supporting surface 7011 is pressed against the first contact surface 1405 and the second engaging hook 7021 is engaged with the second engaging groove 1403, the slide plate 1 is perpendicular to the support leg 2, and the table top on the slide plate 1 is parallel to the ground. If the table top needs to be flipped at this time, the handle is manually pulled, and the handle drives the pull rod 14 to move on the sliding plate. After the pull rod 14 moves, the second engaging hook 7021 no longer blocks the second engaging slot 1403, and the first contact surface 1405 also breaks contact with the first supporting surface 7011. At this time, under the action of the table top's own weight, the table top (together with the sliding tray 1 and the pull rod 14) rotates together, and the axis of rotation is the pin. When it rotates until the first engaging surface 1406 and the first contact surface 1405 are close to the first engaging angle surface 7012, the table top is in a state perpendicular to the ground. At this time, the handle is released, and under the action of the spring 17, the first engaging surface 1406 and the first contact surface 1405 are close to the first engaging angle surface 7012. At this time, the sliding tray 1 is in an elastic locking state, and the sliding tray 1 cannot sway, and the table top cannot sway either. When the table top needs to be flipped from perpendicular to the ground to parallel to the ground, continue to pull the handle, and the handle pulls the pull rod 14 to move on the slide plate 1, so that the first card surface 1406 and the first contact surface 1405 on the pull rod 14 are out of contact with the first snap angle surface 7012. At this time, the user can flip the table top, so that the table top is rotated again to the state where the first supporting surface 7011 is close to the first contact surface 1405, and the second snap hook 7021 is snapped together with the second slot 1403. Due to the elastic force of the spring 17, the table top is always in a locked state (i.e., it cannot shake) regardless of whether it is perpendicular to the ground or parallel to the ground. During the above-mentioned rotation of the table top, the first snap block 701 needs to enter and exit the slide plate 1 through the first through hole, and the second snap block 702 needs to enter and exit the slide plate 1 through the second through hole.

[0049] Therefore, in the flip table, the table top is in a locked state in both states. When the table top is locked, it cannot shake, which reduces the probability of the table top being damaged.

[0050] In the specific flip table, a connecting piece 13 is provided on the slide plate 1, and the table top (not shown in the drawings) is fixed together with the connecting piece 13 by bolts or screws 12, and there are no less than two connecting pieces 13 on the same slide plate 1, and the connecting pieces 13 on the same slide plate 1 are in a parallel state.

[0051] As attached Figure 3 , 5As shown in Figure 6, a first arc transition surface 7013 is provided on the first locking block 701, and the two ends of the first arc transition surface 7013 are respectively connected to the first locking angle surface 7012 and the first supporting surface 7011; a second guide clamping inclined surface 7022 is provided on the second locking block 702, and a second guide inclined surface 1402 is provided at the second locking groove 1403 of the pull rod 14, and the second guide clamping inclined surface 7022 is used to contact the second guide inclined surface 1402.

[0052] Since the first engaging surface 1406 and the first contact surface 1405 on the pull rod 14 may contact the first engaging block 701 during the rotation of the table top, a first arc transition surface 7013 is set on the first engaging block 701. The first arc transition surface 7013 is used to contact the first engaging angle surface 7012 and the first supporting surface 7011. This can minimize the wear of the first engaging block 701 and the pull rod 14 and reduce the resistance encountered when the table top rotates.

[0053] A second guide clamp slope 7022 is provided on the second locking block 702 (the second guide clamp slope 7022 is located on the side of the second locking hook 7021), and a second guide slope 1402 is provided at the second locking groove 1403 of the pull rod 14. The second guide clamp slope 7022 is used to contact the second guide slope 1402. This is to ensure that the second locking hook 7021 slides into the second locking groove 1403 more smoothly and reduce the resistance encountered when the second locking hook 7021 is engaged with the second locking groove 1403.

[0054] As attached Figure 6 As shown in FIG. 7 , it also includes an extension rod 10, a plurality of inserts 1401 and a plurality of embedding grooves 1404 are provided on the pull rod 14, a plurality of sockets 1001 and a plurality of embedding hooks 1003 are provided on the extension rod 10, some of the inserts 1401 on the pull rod 14 cooperate with some of the sockets 1001 on the extension rod 10, some of the embedding grooves 1404 on the pull rod 14 cooperate with some of the embedding hooks 1003 on the extension rod 10, and the handle is plugged and matched with the extension rod 10.

[0055] Specifically, the inserts 1401 on the pull rod 14 are square inserts 1401, and there are two rows of inserts 1401 on the pull rod 14, and the distance between two adjacent inserts 1401 in each row of inserts 1401 is equal, and the two rows of inserts 1401 are in a parallel state, and the sockets 1001 on the extension rod 10 are square sockets 1001, and the two rows of sockets 1001 on the extension rod 10 are in a parallel state, and the distance between two adjacent sockets 1001 in each row of sockets 1001 on the extension rod 10 is equal, and some of the inserts on the pull rod 14 The sheet 1401 cooperates with the partial insertion hole 1001 on the extension rod 10, and the partial embedding groove 1404 on the pull rod 14 cooperates with the partial embedding hook 1003 on the extension rod 10, which is equivalent to the pull rod 14 and the extension rod 10 forming a rod together. The length of the rod can be adjusted appropriately as needed, so that the relative distance between the handle and the crossbeam can be adjusted. Since the distance between the handle and the crossbeam can be adjusted appropriately according to usage requirements, the sliding plate can adapt to the installation of table tops of different widths.

[0056] As attached Figure 2 As shown, the slide plate 1 is a flat-bottomed U-shaped slide plate 1, a limit slide column 1501 is provided on the slide plate 1, a limit slide hole 1002 is provided on the pull rod 14 or the extension rod 10, and the limit slide column 1501 is located in the limit slide hole 1002.

[0057] Specifically, it also includes an auxiliary plate 15, which is fixed on the sliding plate 1 by screws 12. The auxiliary plate 15 and the sliding plate 1 form a clamping space similar to a U-shaped clamping space. The pull rod 14 (and the extension rod 10) slide in the clamping space similar to a U-shaped clamping space, which can further improve the stability of the pull rod 14 when sliding. The limiting sliding column 1501 is opened on the auxiliary plate 15, and the limiting sliding column 1501 is perpendicular to the auxiliary plate 15, the pull rod 14 and the extension rod 10.

[0058] The flat-bottomed U-shaped sliding tray 1 allows the pull rod 14 (and the extension rod 10 ) to slide stably inside the sliding tray 1 , because the flat-bottomed U-shaped sliding tray 1 itself is equivalent to a slide groove.

[0059] The function of the above-mentioned limiting sliding hole and limiting sliding column 1501 is to limit the sliding amount of the pull rod 14 (and the extension rod 10) on the sliding tray 1. When the limiting sliding column 1501 is close to the limit position of the limiting sliding hole, the pull rod 14 will not be able to continue to slide on the sliding tray 1.

[0060] Specifically, the limiting sliding column 1501 is a cylindrical limiting sliding column 1501, and the limiting sliding hole is a waist-shaped limiting sliding hole.

[0061] As attached Figure 3As shown in FIG. 5 , a square plug-in hole 703 is provided on the support 7, and the crossbeam is a square tubular crossbeam. The crossbeam and the square plug-in hole 703 are matched together, and the support 7 and the crossbeam are fixed together by a bolt assembly.

[0062] Specifically, the square tube-shaped crossbeam is inserted into the inserting square hole 703, and the crossbeam and the support 7 are fixed together by a bolt assembly, and can be disassembled and assembled as needed.

[0063] At the same time, in order to facilitate the rapid assembly of the crossbeam on the support 7, two side panels 704 can be set on the support 7. The two side panels 704 are located at the openings of the plug-in square holes 703. The two side panels 704 are in a parallel state, and the two side panels 704 are respectively pressed against the crossbeam from both sides.

[0064] As attached Figure 5 As shown, it also includes a cover 8, the support leg 2 is a hollow square tubular support leg 2, the support base 7 is inserted into the support leg 2, a side hole 705 is opened on the support base 7, the cover 8 is arranged on the support base 7, and the elastic hook 801 on the cover 8 cooperates with the side hole 705.

[0065] Specifically, the function of the cover 8 is to cover the support 7. Since the cover 8 is matched with the side hole 705 on the support 7 through its own elastic hook 801, the cover 8 can be removed from the support 7 as needed.

[0066] As attached Figure 1 As shown in Figure 2, the crossbeam includes an inner crossbeam 502 and an outer crossbeam 501, both of which are in the shape of hollow square tubes. The inner crossbeam 502 consists of two, and the two inner crossbeams 502 are respectively sleeved on the two ends of the outer crossbeam 501, and the two inner crossbeams 502 are respectively matched with two supports 7; the handle includes an inner hand rod 1101 and an outer hand rod 1102, both of which are in the shape of hollow tubes. There are two inner hand rods 1101, and the two inner hand rods 1101 are respectively sleeved on the two ends of the outer hand rod 1102, and the inner hand rod 1101 is used to indirectly cooperate with the support 7.

[0067] Specifically, the two inner cross beams 502 are respectively sleeved at the two ends of the outer cross beam 501, and the inner cross beam 502 and the outer cross beam 501 are fixed together by screws 12 or bolts, which is equivalent to that the length of the entire cross beam can be adjusted according to the use needs. In order to adapt to the adjustable design of the above cross beam length, the two inner hand rods 1101 are respectively sleeved at the two ends of the outer hand rod 1102, and the inner hand rod 1101 and the outer hand rod 1102 are fixed together by screws 12 or bolts. The inner hand rod 1101 and the outer hand rod 1102 together form a handle with adjustable length. The inner hand rod 1101 is plugged and fixed with the extension rod 10 on the pull rod 14. Since the length of the cross beam and the handle can be adjusted according to needs, the table board used for the entire table can also be selected according to needs.

[0068] Specifically, the inner cross beam 502 is inserted into the inserting square hole 703 of the support 7 and is fixed on the support 7 by a bolt assembly.

[0069] As attached Figure 1 As shown, a stabilizing frame 3 is provided on the supporting foot 2 , and wheels 4 are installed on the stabilizing frame 3 .

[0070] As attached Figure 4 As shown in FIG. 6 , the spring 17 is located between the sliding plate 1 and the pull rod 14 , and the spring 17 is parallel to the sliding plate 1 and the pull rod 14 , one end of the spring 17 directly or indirectly abuts against the sliding plate 1 , and the other end of the spring 17 directly or indirectly abuts against the pull rod 14 .
