[0001] The invention relates to the technical field of office furniture, in particular to a multifunctional desk. Background Art

[0002] Office desks refer to desks that are used for the convenience of work in daily life and social activities. Office desks are divided into panel desks, metal desks, soft desks, etc. The structure of panel desks includes a metal bracket, a table mounted on the metal bracket, and a screen set on the table. The structure of the screen usually includes two mounting seats mounted on the table, and a partition clamped between the two mounting seats at the bottom.

[0003] For example, in a panel desk with four workstations, two or four screens will be installed on the desk. When two screens are installed, the two screens are arranged along the length of the table top to separate the two facing workstations; when four screens are installed, the other two screens of the four screens will separate the two adjacent workstations.

[0004] In the actual installation process of the panel desk for four people, some people will choose to install four screens for privacy, some will install two screens for aesthetics, and some will install three screens for the convenience of one person using two adjacent workstations. At this time, four screens will be uniformly equipped as accessories. Because it is unclear whether there will be changes in the later needs, the extra screens will not be directly discarded after installation, so there is a storage problem for the remaining screens after installation. Summary of the invention

[0007] By adopting the above technical scheme, considering the panel office desk with four working stations, the length of the area occupied by a single person is usually 1-1.2 meters, and the width is usually 0.6 meters. At this time, the length of the first partition is usually greater than the length of the second partition, thereby providing feasibility for the operation of storing the second partition on the first partition after being rotated; if the second partition does not need to be used in full, first unlock the connecting component and turn the end of the second partition away from the intermediate tube seat into a rotating state, then rotate the second partition toward the first accommodating groove and embed it in the first accommodating groove, or rotate toward the second accommodating groove and embed it in the second accommodating groove for storage, and finally fix the second partition on the first partition through the connecting component, which finally has the function of facilitating the selection of suitable partitions for use according to needs and facilitating the storage of partitions that do not need to be used; at the same time, when the first partition and the second partition are installed, by setting the intermediate tube seat, the installation positions of the first partition and the second partition can be positioned, thereby improving the installation neatness of the first partition and the second partition.

[0008] The present invention is further configured as follows: a first limit sleeve is embedded in the position where the table corresponds to the connecting component that limits the rotation of the second partition, a mounting groove extending from top to bottom is provided at the end of the second partition away from the intermediate tube seat, a threaded hole is provided at the bottom of the mounting groove that penetrates through the bottom of the second partition, and a telescopic hole is provided at the end of the second partition away from the intermediate tube seat that communicates with the mounting groove, and the connecting component includes a countersunk limit screw threadedly connected in the threaded hole and the lower end of which is used to be embedded in the first limit sleeve, a locking tongue telescopically arranged in the telescopic hole, a first elastic structure arranged between the second partition and the locking tongue and which keeps the locking tongue from passing through the side of the second partition, and a linkage structure arranged between the countersunk limit screw and the locking tongue; when the countersunk limit screw is separated from the first limit sleeve and continues to rotate upward, the linkage structure overcomes the elastic force of the first elastic structure so that the locking tongue passes through the side of the second partition, and a second limit sleeve for the locking tongue to be embedded is provided at the position of the first partition corresponding to the locking tongue.

[0009] By adopting the above technical solution, by setting a first limit sleeve on the table top, the countersunk limit screw of the connecting assembly can be embedded in the first limit sleeve during the downward threaded connection process, so as to limit the rotation of the end of the second partition away from the intermediate tube seat, so as to fix the second partition; and when the countersunk limit screw is separated from the first limit sleeve, the rotation of the end of the second partition away from the intermediate tube seat is unlocked; at the same time, when the second partition is embedded in the first embedding groove or the second embedding groove of the first partition, by continuing to rotate the countersunk limit screw upward, the linkage structure overcomes the elastic force of the first elastic structure so that the locking tongue passes through the side of the second partition, thereby being embedded in the second limit sleeve of the first partition, so as to fix the second partition on the first partition.

[0010] The present invention is further configured as follows: the first elastic structure includes connecting plates arranged at the upper and lower ends of the lock tongue, a first guide shaft arranged on the telescopic hole and passing through the connecting plate, a first compression spring sleeved on the first guide shaft, and an anti-detachment cover threadedly arranged on the first guide shaft and preventing the first compression spring from detaching.

[0011] By adopting the above technical solution, the first elastic structure includes connecting plates arranged at the upper and lower ends of the lock tongue, a first guide shaft arranged on the telescopic hole and passing through the connecting plate, a first compression spring sleeved on the first guide shaft, and an anti-detachment cover threadedly arranged on the first guide shaft and preventing the first compression spring from detaching. At this time, the first compression spring can drive the lock tongue to move in the direction close to the installation groove to ensure that the lock tongue does not pass through the side of the second partition in the initial state.

[0012] The present invention is further configured as follows: the linkage structure includes a frustum arranged on the circumferential side of the portion of the countersunk limit screw located in the mounting groove, and a pressing bevel block arranged at one end of the lock tongue; when the countersunk limit screw is separated from the first limit sleeve and continues to rotate upward, the frustum overcomes the elastic force of the first elastic structure and drives the pressing bevel block to move in a direction away from the mounting groove.

[0013] By adopting the above-mentioned technical scheme, since the countersunk limit screw is in a state of spiral rotation during use, the linkage structure includes a frustum arranged on the circumferential side of the part of the countersunk limit screw located in the mounting groove, and a pressing bevel block arranged at one end of the lock tongue, thereby achieving the effect of overcoming the elastic force of the first elastic structure and driving the pressing bevel block to move in a direction away from the mounting groove during the upward movement of the countersunk limit screw, so that the lock tongue protrudes and is embedded in the first limiting groove of the first partition.

[0014] The present invention is further configured as follows: eight rotating components for connecting the first partition or the second partition are sleeved on the intermediate tube seat, the rotating component includes a rotating ring sleeved on the intermediate tube seat, a support rod at one end arranged on the rotating ring, and a connecting seat arranged at the other end of the support rod, any one of the first partition and the second partition is respectively fixed to the connecting seats of two rotating components at different heights; the rotating rings of the four rotating components located at the bottom are stacked, and the four rotating components are respectively connected to the two first partitions and the two second partitions, and the rotating rings of the four rotating components located at the top are stacked, and a shelf seat supported on the table and for the lowest rotating ring to rest is provided at the bottom of the intermediate tube seat, and a partition sleeve between the four rotating rings located at the bottom and the four rotating rings located at the top is sleeved on the intermediate tube seat, and an end cover that abuts against the highest rotating ring is threadedly connected to the intermediate tube seat; the limiting component includes a third limiting sleeve embedded in the table, and a limiting pin arranged below the end of the first partition away from the intermediate tube seat and used to be embedded in the third limiting sleeve.

[0015] By adopting the above technical solution, a plurality of rotating components are set to realize the connection between the two first partitions and the second partition, which has the effect of facilitating production, so that the plurality of rotating components used to install the first partition and the second partition are universal parts, which makes the installation of the rotating components very convenient, and can be directly put on the middle pipe seat without worrying about the sequence; at the same time, the rotating rings of the four rotating components located at the bottom are stacked, and the four rotating components are respectively connected to the two first partitions and the two second partitions, and the rotating rings of the four rotating components located at the top are stacked, which can ensure the distance between the two connection points of the two rotating components to the first partition and the second partition, thereby improving the structural stability after installation, and the stacked arrangement, in conjunction with the setting of the separation sleeve, makes the rotating components at a suitable height when connected to the first partition and the second partition.

[0016] A further setting of the present invention is that: the metal bracket includes a square support frame and three leg brackets in a "凵" shape arranged at the bottom of the support frame. A slide rail is arranged on the inner side of the support frame along the length direction. The cross-section of the chute of the slide rail is in a "口" shape. A plurality of support components that can be fixed at any position after sliding are slidably connected between two adjacent slide rails. The plurality of support components support the lower surface of the table board.

[0017] By adopting the above technical solution, by arranging a plurality of slidable support components, the plurality of support components support the lower surface of the table board, so as to improve the support effect on the table board and prevent problems such as deformation of the table board during long-term use.

[0018] A further setting of the present invention is that: the support component includes two sliding sleeves respectively slidably connected to two slide rails, a support square tube, and two threaded shafts arranged at both ends of the support square tube with opposite thread directions. The two threaded shafts are respectively threadedly connected to the sliding sleeves. The support square tube supports the lower surface of the table board. A limiting tooth groove is arranged in the chute, and a limiting tooth block for engaging with the limiting tooth groove is arranged on the sliding sleeve.

[0019] By adopting the above technical solution, the support position of the support square tube can be adjusted as the sliding sleeve slides. After the support square tube is adjusted to a suitable position, by rotating the support square tube, the two sliding sleeves move in a direction away from each other, so that the sliding sleeves are抵紧 against the chute of the slide rail, thereby realizing the fastening of the support component.

[0020] A further setting of the present invention is that: a through hole is arranged in the middle of the table board, and a threaded installation part is arranged at the bottom of the middle pipe seat and penetrates downward through the through hole. The support square tube of one of the support components is located below the through hole. A threaded groove corresponding to the threaded installation part is arranged on the support square tube located below the through hole. The threaded installation part is threadedly connected in the threaded groove.

[0021] By adopting the above technical solution, by making the support square tube of one of the support components located below the through hole, at this time, the support square tube can support the middle part of the table board. At the same time, the threaded installation part of the middle pipe seat is threadedly connected in the threaded groove of the support square tube, so as to facilitate the installation of the middle pipe seat.

[0022] The present invention is further configured as follows: a total of five support components are provided, and adjustment seats with threaded shafts are slidably provided at the ends of the support square tubes of two of the support components located at the edge, and when the support square tubes are rotated to a state of supporting the table plate, the support square tubes and the adjustment seats slide relative to each other in the horizontal direction; in the support component located at the edge, a second elastic structure is provided between the sliding sleeve and the support square tube to drive the support square tube to have a tendency to slide toward an adjacent support component, and a clamping cavity is formed between the support square tube located at the edge and the support square tube adjacent to it; a connecting bracket is provided on the lower surface of the table plate, which is embedded in the clamping cavity during the vertical downward placement process, and a card groove for the support square tube to be embedded is provided on one side of the connecting bracket close to the support square tube located at the edge, and the other side of the connecting bracket is in conflict with the side surface of another support square tube, and a guiding structure is provided between the connecting bracket and the support square tube located at the edge, which first overcomes the elastic force of the second elastic structure during the vertical downward placement of the table plate to allow the support square tube to move outward.

[0023] By adopting the above technical solution, the metal bracket and the table top are involved in the fixation problem. Usually, the table top is fixed by multiple bolts, but there is an inconvenience in operation when fixing by bolts. At this time, by further optimizing the support assembly located at the edge, when the table top is placed vertically downward, the guide structure overcomes the elastic force of the second elastic structure to make the supporting square tube move outward. After the table top is installed in place, the supporting square tube is re-embedded in the card slot of the connecting bracket under the action of the second elastic structure; at the same time, the through hole during the installation of the intermediate tube seat is moved to the position of the threaded groove matching the supporting square tube located in the middle for positioning, which facilitates the installation of the table top.

[0024] The present invention is further configured as follows: the second elastic structure includes a base plate arranged on the side of the supporting square tube, a second guide shaft arranged on the side of the adjusting seat and passing through the base plate, a second compression spring sleeved on the part of the second guide shaft that does not pass through the base plate, and an anti-slip nut threadedly arranged on the end of the second guide shaft; the guide structure includes a first guide bevel arranged under the connecting bracket and a second guide bevel arranged on the supporting square tube. When the table plate is placed vertically downward on the metal bracket, the first guide bevel and the second guide bevel gradually collide with each other to overcome the elastic force of the second elastic structure and allow the supporting square tube to move outward.

[0025] By adopting the above-mentioned technical scheme, the second elastic structure includes a base plate, a second guide shaft, a second compression spring, and an anti-drop nut, so as to overcome the elastic force of the second elastic structure to allow the supporting square tube to move outward, and after the action on the second elastic structure is cancelled, the supporting square tube can be driven to reset; the setting of the first guide slope and the second guide slope, when the table plate is placed vertically downward, can conveniently drive the sliding sleeve to overcome the action of the second elastic structure and move during the installation process of the table plate under the action of its own gravity, which has the effect of facilitating the installation of the table plate.

One of the first partitions 32 is provided with a first accommodating groove 322 on one side facing the width direction of the table top 2, and the other first partition 32 is provided with a second accommodating groove 323 on the other side facing the width direction of the table top 2; one end of the second partition 33 is rotatably connected to the intermediate tube seat 31, and the connecting component 35 is used to limit or unlock the rotation of the end of the second partition 33 away from the intermediate tube seat 31, one of the second partitions 33 can be accommodated in the first accommodating groove 322 after rotating toward the first accommodating groove 322, and the other second partition 33 can be accommodated in the second accommodating groove 323 after rotating toward the second accommodating groove 323; when the second partition 33 is accommodated in the first accommodating groove 322 and the second accommodating groove 323, the connecting component 35 is also used to fix the second partition 33 on the first partition 32.

[0031] like Figures 2 to 4 As shown, a first limiting sleeve 21 is embedded in the position where the table plate 2 corresponds to the connecting component 35 for limiting the rotation of the second partition 33, a mounting groove 331 extending from top to bottom is provided at the end of the second partition 33 away from the intermediate tube seat 31, a threaded hole 332 penetrating to the bottom of the second partition 33 is provided at the bottom of the mounting groove 331, and a telescopic hole 333 communicating with the mounting groove 331 is provided at the end of the second partition 33 away from the intermediate tube seat 31, the connecting component 35 includes a countersunk limit screw 351 threadedly connected in the threaded hole 332 and with the lower end thereof embedded in the first limiting sleeve 21, a locking tongue 352 telescopically arranged in the telescopic hole 333, a first elastic structure 353 arranged between the second partition 33 and the locking tongue 352 and preventing the locking tongue 352 from passing through the side of the second partition 33, and a linkage structure 354 arranged between the countersunk limit screw 351 and the locking tongue 352. When the countersunk stop screw 351 is separated from the first stop sleeve 21 and continues to rotate upward, the linkage structure 354 overcomes the elastic force of the first elastic structure 353 so that the lock tongue 352 passes through the side of the second partition 33, and the first partition 32 is provided with a second stop sleeve 321 for the lock tongue 352 to be embedded in at the position corresponding to the lock tongue 352. A protective ring (not marked in the figure) surrounding the lock tongue 352 is installed on the side of the second partition 33, and a dust plug (not marked in the figure) covering the top of the installation groove 331 is installed on the top of the second partition 33.

[0032] like Figure 4 and Figure 5As shown, the first elastic structure 353 includes connecting pieces 3531 arranged at the upper and lower ends of the lock tongue 352, a first guide shaft 3532 arranged on the telescopic hole 333 and passing through the connecting piece 3531, a first compression spring 3533 sleeved on the first guide shaft 3532, and an anti-detachment cover 3534 threadedly arranged on the first guide shaft 3532 to prevent the first compression spring 3533 from detaching. The linkage structure 354 includes a round table 3541 arranged on the circumference of the part of the countersunk limit screw 351 located in the installation groove 331, and a pressing inclined block 3542 arranged at one end of the lock tongue 352; when the countersunk limit screw 351 is separated from the first limit sleeve 21 and continues to rotate upward, the round table 3541 overcomes the elastic force of the first elastic structure 353 and drives the pressing inclined block 3542 to move in a direction away from the installation groove 331.

[0033] like Figure 2 , Figure 3 and Figure 6 As shown, eight rotating components 36 for connecting the first partition 32 or the second partition 33 are sleeved on the intermediate tube seat 31. The rotating component 36 includes a rotating ring 361 sleeved on the intermediate tube seat 31, a support rod 362 with one end arranged on the rotating ring 361, and a connecting seat 363 arranged at the other end of the support rod 362. Any first partition 32 or second partition 33 is respectively fixed to the connecting seats 363 of the rotating components 36 at two different heights. The rotating rings 361 of the four rotating components 36 located at the bottom are stacked, and the four rotating components 36 are respectively connected to the two first partitions 32 and the two second partitions 33. The rotating rings 361 of the four rotating components 36 located at the top are stacked, and a shelf 311 supported on the table 2 and for the bottom rotating ring 361 to be placed is provided at the bottom of the middle pipe seat 31. The middle pipe seat 31 is sleeved with a separation sleeve 312 between the four rotating rings 361 located at the bottom and the four rotating rings 361 located at the top, and the middle pipe seat 31 is threadedly connected with an end cover 313 that abuts against the top rotating ring 361. The limiting component 34 includes a third limiting sleeve 341 embedded in the table 2, and a limiting pin 342 disposed below the end of the first partition 32 away from the middle pipe seat 31 and used to be embedded in the third limiting sleeve 341.

[0034] Implementation effect: Considering the panel desk with four working positions, the length of the area occupied by a single person is usually 1-1.2 meters, and the width is usually 0.6 meters. At this time, the length of the first partition 32 is usually greater than the length of the second partition 33, thereby providing feasibility for the operation of storing the second partition 33 on the first partition 32 after rotation; if the second partition 33 does not need to be used in its entirety, first unlock the connecting assembly 35 and change the end of the second partition 33 away from the middle pipe seat 31 to a rotating state, and then rotate the second partition 33 toward the first receiving groove 322 The second partition 33 is then embedded in the first accommodating groove 322, or rotated toward the second accommodating groove 323 and then embedded in the second accommodating groove 323 for storage, and finally the second partition 33 is fixed to the first partition 32 through the connecting component 35, which finally has the function of conveniently selecting suitable partitions for use according to needs and conveniently storing unnecessary partitions; at the same time, when the first partition 32 and the second partition 33 are installed, by setting the intermediate pipe seat 31, the installation positions of the first partition 32 and the second partition 33 can be positioned, thereby improving the installation neatness of the first partition 32 and the second partition 33.

[0035] By setting the first limit sleeve 21 on the table top 2, the countersunk limit screw 351 of the connecting assembly 35 can be embedded in the first limit sleeve 21 during the downward threaded connection process, so as to limit the rotation of the end of the second partition 33 away from the intermediate tube seat 31, so as to fix the second partition 33; and when the countersunk limit screw 351 is separated from the first limit sleeve 21, the rotation of the end of the second partition 33 away from the intermediate tube seat 31 is unlocked; at the same time, when the second partition 33 is embedded in the first embedding groove or the second embedding groove of the first partition 32, by continuing to rotate the countersunk limit screw 351 upward, the linkage structure 354 overcomes the elastic force of the first elastic structure 353 so that the locking tongue 352 passes through the side of the second partition 33, thereby being embedded in the second limit sleeve 321 of the first partition 32, so as to fix the second partition 33 on the first partition 32.

[0036] The first elastic structure 353 includes connecting pieces 3531 arranged at the upper and lower ends of the locking tongue 352, a first guiding shaft 3532 arranged on the telescopic hole 333 and passing through the connecting pieces 3531, a first compression spring 3533 sleeved on the first guiding shaft 3532, and an anti - detachment cover 3534 thread - arranged on the first guiding shaft 3532 to prevent the first compression spring 3533 from detaching. At this time, the first compression spring 3533 can drive the locking tongue 352 to move towards the direction close to the installation groove 331, so as to ensure that the locking tongue 352 does not protrude from the side surface of the second partition 33 in the initial state. Since the countersunk head limit screw 351 is in a state of spiral rotation during use, the linkage structure 354 includes a frustum 3541 arranged on the circumferential side of the part of the countersunk head limit screw 351 located in the installation groove 331, and a pressing inclined block 3542 arranged at one end of the locking tongue 352. Thus, during the upward movement of the countersunk head limit screw 351, it can overcome the elastic force of the first elastic structure 353 and drive the pressing inclined block 3542 to move away from the installation groove 331, so that the locking tongue 352 protrudes and is embedded in the first limiting groove of the first partition 32.

[0037] By arranging a plurality of rotating components 36 to connect the two first partitions 32 and the second partition 33, it has the function of facilitating production at this time. The plurality of rotating components 36 for installing the first partition 32 and the second partition 33 are common parts, making the installation of the rotating components 36 very convenient. They can be directly sleeved on the middle pipe seat 31 without worrying about the sequence; at the same time, the rotating rings 361 of the four rotating components 36 located below are stacked. These four rotating components 36 are respectively connected to the two first partitions 32 and the two second partitions 33. The rotating rings 361 of the four rotating components 36 located above are stacked, which can ensure the distance between the two connection points of the two rotating components 36 to the first partition 32 and the second partition 33, thereby improving the structural stability after installation. And they are stacked on each other, combined with the setting of the separation sleeve 312, so that when the rotating components 36 are connected to the first partition 32 and the second partition 33, the rotating components 36 are already at an appropriate height.

[0038] Embodiment 2: A multifunctional office desk, as Figure 1 and Figure 8 shown, the difference from Embodiment 1 is that the metal bracket 1 includes a square support frame 11 and three "凵"-shaped leg brackets 12 arranged at the bottom of the support frame 11. A slide rail 13 is arranged on the inner side of the support frame 11 along the length direction. The cross - section of the chute 131 of the slide rail 13 is in the shape of a "mouth". Five support components 14 that can be fixed at any position are slidably connected between two adjacent slide rails 13, and the plurality of support components 14 support the lower surface of the table board 2.

The two threaded shafts 143 are respectively threadedly connected to the sliding sleeves 141, and the supporting square tube 142 is supported on the lower surface of the table plate 2. A limiting tooth groove 132 is arranged in the sliding groove 131, and a limiting tooth block 1411 for engaging with the limiting tooth groove 132 is arranged on the sliding sleeve 141.

[0040] like Figures 8 to 10 As shown, the middle of the table 2 is provided with a through hole 22, an intermediate pipe seat 31 (see Figure 3 ) A threaded mounting portion 314 is provided at the bottom and passes through the through hole 22 downward. The supporting square tube 142 of the supporting assembly 14 located in the middle is located below the through hole 22. A threaded groove 1421 corresponding to the threaded mounting portion 314 is provided on the supporting square tube 142 located below the through hole 22. The threaded mounting portion 314 is threadedly connected in the threaded groove 1421.

[0041] like Figures 8 to 11 As shown, there are five support assemblies 14 in total. The ends of the support square tubes 142 of the two support assemblies 14 located at the edge are slidably provided with adjustment seats 144 having threaded shafts 143. When the support square tubes 142 are rotated to a state where the table 2 is supported, the support square tubes 142 and the adjustment seats 144 slide relatively in the horizontal direction. In the support assemblies 14 located at the edge, a second elastic structure 15 is provided between the sliding sleeve 141 and the support square tube 142 to drive the support square tube 142 to have a tendency to slide toward the adjacent support assemblies 14. A clamping cavity is formed between the support square tube 142 located at the edge and the support square tube 142 adjacent thereto. A connecting bracket 23 is provided on the lower surface of the table top 2 and is embedded in the clamping cavity during the vertical downward placement process. A slot 24 for the supporting square tube 142 to be embedded is provided on one side of the connecting bracket 23 close to the supporting square tube 142 located at the edge. The other side of the connecting bracket 23 is in conflict with the side surface of another supporting square tube 142. A guiding structure is provided between the connecting bracket 23 and the supporting square tube 142 located at the edge to first overcome the elastic force of the second elastic structure 15 so that the supporting square tube 142 moves outward during the vertical downward placement of the table top 2.

[0042] The second elastic structure 15 includes a base plate 151 disposed on the side of the supporting square tube 142, a second guide shaft 152 disposed on the side of the adjusting seat 144 and passing through the base plate 151, a second compression spring 153 sleeved on the portion of the second guide shaft 152 that does not pass through the base plate 151, and an anti-slip nut 154 threadedly disposed at the end of the second guide shaft 152. The guide structure includes a first guide slope 41 disposed below the connecting bracket 23 and a second guide slope 42 disposed on the supporting square tube 142. When the table 2 is placed vertically downward on the metal bracket 1, the first guide slope 41 and the second guide slope 42 gradually collide with each other to overcome the elastic force of the second elastic structure 15 and allow the supporting square tube 142 to move outward.

[0043] Implementation effect: By setting a plurality of slidable support components 14, the plurality of support components 14 are supported on the lower surface of the table 2, thereby improving the support effect on the table 2, and preventing the table 2 from deforming during long-term use. The support square tube 142 can adjust the position of the support as the sliding sleeve 141 slides, and after the support square tube 142 is adjusted to a suitable position, the two sliding sleeves 141 are moved in a direction away from each other by rotating the support square tube 142, so that the sliding sleeve 141 is tightly pressed against the slide groove 131 of the slide rail 13, thereby fastening the support component 14.

[0044] By positioning the supporting square tube 142 of one of the supporting assemblies 14 below the through hole 22, the supporting square tube 142 can support the middle of the platform 2, and the threaded mounting portion 314 of the intermediate tube seat 31 is threadedly connected in the threaded groove 1421 of the supporting square tube 142 to facilitate the installation of the intermediate tube seat 31.

[0045] There is a fixation issue involved between the metal bracket 1 and the table top 2. Usually, the table top 2 is fixed by multiple bolts, but there is an inconvenience in operation when fixing by bolts. At this time, by further optimizing the support assembly 14 located at the edge, when the table top 2 is placed vertically downward, the guiding structure overcomes the elastic force of the second elastic structure 15 to make the supporting square tube 142 move outward. After the table top 2 is installed in place, the supporting square tube 142 is re-embedded in the slot 24 of the connecting bracket 23 under the action of the second elastic structure 15; at the same time, the through hole 22 during the installation of the intermediate tube seat 31 is moved to the position of the threaded groove 1421 matching the supporting square tube 142 located in the middle for positioning, which facilitates the installation of the table top 2. The second elastic structure 15 includes a base plate 151, a second guide shaft 152, a second compression spring 153, and an anti-slip nut 154, so as to overcome the elastic force of the second elastic structure 15 to allow the supporting square tube 142 to move outward, and after the action on the second elastic structure 15 is cancelled, the supporting square tube 142 can be driven to reset; the setting of the first guide bevel 41 and the second guide bevel 42, when the table plate 2 is placed vertically downward, can conveniently drive the sliding sleeve 141 to overcome the action of the second elastic structure 15 and move during the installation process of the table plate 2 under the action of its own gravity, which has the effect of facilitating the installation of the table plate 2.
