Description

Technical Field

[0001] The present application relates to the technical field of furniture, and in particular to an office desk. Background Art

[0002] An office desk is a table that is equipped for convenient work.

[0003] The existing office desk includes a main table, a sub-table with one end rotatably set on the main table desktop through a rotating component and the other end supported on the ground by a supporting frame. The main table and the sub-table cooperate to form the entire office area. Rotating the sub-table can also achieve certain adjustments to the office area.

[0004] Office desks are prefabricated structures for ease of transportation. The main desk, sub-desk, support frame, and connecting components are disassembled for transportation, and then fixed and connected by screws after transportation. However, the various parts of the Bao Gong desk must correspond to each other one by one. Therefore, if a part is lost during transportation, the assembly cannot be completed, making the assembly of the office desk very inconvenient. At the same time, the rotating component is installed on the main desk surface, so it is necessary to open multiple threaded holes on the main desk surface. Multiple threaded holes will damage the main desk surface, and the main desk is made of wood. The threaded holes opened on the wood material are easily damaged, which makes the stability between the main desk and the sub-desk poor, reducing the stability of the office desk when in use. Summary of the invention

[0005] In order to improve the convenience of assembling the office desk, make the main desk surface more beautiful and improve the stability of the office desk when in use, the present application provides an office desk.

[0006] The present application provides an office desk, which adopts the following technical solution: An office desk comprises a main desk, and a sub-desk with one end rotatably arranged on the main desk surface by a rotating mechanism and the other end supported on the ground by a supporting mechanism, wherein a mounting hole is provided on the main desk surface, and the rotating mechanism comprises: A mounting plate, which is placed on the main table top and is provided with a mounting rod that is plugged into the mounting hole; A positioning assembly, the positioning assembly is used to position the mounting rod; A rotating assembly, which is arranged on the mounting plate and connected to the auxiliary table and is used to realize the rotation connection between the auxiliary table and the main table; The supporting mechanism comprises: A mounting seat, the mounting seat is arranged on the auxiliary table; A support frame, the support frame is rotatably arranged on the mounting seat in a direction close to or away from the mounting rod and supported on the ground for positioning; The connecting assembly is arranged on the supporting frame; when transportation is required, the supporting frame is rotated away from the ground and close to the mounting rod and finally connected with the mounting rod through the connecting assembly.

[0007] By adopting the above technical solution, during transportation, the support frame is rotated close to the mounting rod, and then the connecting assembly fixes the support frame and the mounting rod. At the same time, the rotation points of the support frame and the mounting seat and the mounting rod are respectively located at the two ends of the sub-table, so that the support frame can be transported with a smaller volume and is more convenient for transportation. After the transportation is completed, the mounting plate on the sub-table is set on the main table, and the mounting rod is plugged into the mounting hole. At the same time, the connecting assembly is unlocked, the support frame is rotated away from the mounting rod, and the mounting rod is placed on the ground to support the sub-table. Finally, the positioning assembly is used to position the mounting rod, so that the sub-table is rotated and installed on the main table, and the support frame is pressed against the ground for support and positioning.

[0008] During the transportation process, multiple main tables are transported together, and the support frame is rotated and connected to the installation rod for transportation, thereby reducing the space occupied by the transportation of the auxiliary table. In addition, the main table is larger in size and not easy to lose, and the auxiliary table, support frame and rotating assembly are connected to each other for transportation, which greatly reduces the probability of parts falling and causing assembly inconvenience.

[0009] Because the rotating assembly will not be removed later, only the firmness needs to be considered when connecting the rotating assembly, and the firmness will not be affected by the need to be removed later. Therefore, after the main table and the auxiliary table are rotatably connected through the cooperation of the rotating assembly, the mounting plate, the mounting rod and the positioning assembly, the probability of damage caused by opening threaded holes on the wooden material is greatly reduced, thereby greatly improving the stability of the office desk during use; and there is no need to connect multiple structures with screws during installation, which greatly improves the convenience of assembly and disassembly. At the same time, only one mounting hole needs to be opened on the main table, which greatly improves the aesthetics of the main table.

[0010] Optionally, the positioning component includes: A positioning screw, which is rotatably arranged at the bottom of the mounting rod and has a rotation direction parallel to a rotation direction of the support frame and is used to connect with the connecting assembly; A positioning nut is threadedly connected to the positioning screw, and the positioning nut and the mounting plate are respectively pressed against two side walls of the main table opposite to each other for positioning.

[0011] By adopting the above technical solution, the positioning screw and the mounting rod are passed through the mounting holes in sequence, so that the mounting plate is placed on the main table for positioning, and then the positioning nut is threadedly connected to the positioning screw to achieve positioning of the mounting plate, thereby achieving the rotational connection between the sub-table and the main table.

[0012] When the office desk needs to be transported, the positioning nut is removed from the positioning screw, the sub-table is moved to drive the mounting plate, the mounting rod and the positioning screw to be removed from the main table, and then the positioning nut is threadedly connected to the positioning screw. Then the positioning screw and the support frame are rotated close to each other, and the connecting assembly connects the support frame and the positioning screw together. Then it can be transported and the positioning nut can be positioned, which reduces the probability of the positioning nut being lost, thereby further reducing the probability of parts falling and causing inconvenience to assembly, and improving the convenience of assembling the office desk.

[0013] Optionally, the connection component includes: A connecting tube, wherein the connecting tube is slidably arranged on the support frame; the support frame rotates to drive the connecting tube close to the positioning screw and the positioning screw rotates close to the connecting tube so that the axes of the two coincide; the connecting tube slides close to the positioning screw and is threadedly connected to the positioning screw after rotation and presses against the positioning nut for positioning; The limiting ring is arranged on the outer side wall of the connecting tube and is used to provide leverage when rotating the connecting tube. When the supporting frame is supported on the ground, the connecting tube is pressed against the ground under the action of gravity for positioning.

[0014] By adopting the above technical solution, the support frame rotates to drive the connecting tube to approach the positioning screw, and at the same time the positioning screw rotates to approach the connecting tube, so that the connecting tube is aligned with the positioning screw, and the limiting ring and the connecting tube are pushed against the positioning screw. The limiting ring is rotated to drive the connecting tube threadedly connected to the positioning screw, so that the connecting tube is against the positioning nut for positioning, thereby connecting the support frame and the positioning screw to each other, and the connecting tube can also protect the thread on the positioning screw, thereby reducing the probability of damage to the positioning screw thread during transportation and causing inconvenience in subsequent assembly, while also improving the convenience during connection and the convenience during assembly of the office desk.

[0015] Furthermore, when the support frame is supported on the ground, the connecting tube is pressed against the ground under the action of gravity, thereby realizing the positioning of the connecting tube and reducing the probability of the connecting tube being lost.

[0016] Optionally, a plurality of universal wheels rolling on the ground are rotatably mounted on the bottom of the support frame, and a limit assembly is provided on the support frame. When the universal wheels are supported on the ground, the limit assembly is used to position the connecting tube and the support frame.

[0017] By adopting the above technical solution, the universal wheel rolls on the ground. Therefore, when the sub-table needs to be supported, the support frame is rotated close to the ground to make the universal wheel roll on the ground until the support frame rotates to a vertical state and stops, and then the limit assembly positions the connecting tube and the support frame.

[0018] Therefore, when the support frame is supported on the ground, there is no need to lift the sub-table upwards, which reduces the resistance during rotation and improves the convenience during operation. In addition, the position of the connecting tube and the support frame is positioned by the limit assembly, which reduces the probability of losing the connecting tube and improves the stability of the sub-table, thereby improving the stability of the office desk during use and the convenience of assembly.

[0019] Optionally, when the universal wheel is supported on the ground, the connecting tube is supported on the ground for positioning, and the limiting assembly includes: A limit block, which is slidably disposed on the support frame in a direction close to or away from the connecting tube and is provided with a limit surface that fits the connecting tube; A limit screw is threadedly connected to the support frame and pushes the limit surface to press against the connecting tube for positioning.

[0020] By adopting the above technical solution, when locking is required, the limit ring is pushed downward to press the connecting tube against the ground, and then the limit screw is turned to push the limit surface on the limit block to press against the connecting tube for positioning; when unlocking is required, the limit screw is turned away from the connecting tube, and the connecting tube can rotate freely, thereby unlocking the support frame and the connecting tube, thereby greatly improving the convenience of positioning the support frame and the connecting tube, and the limit component will not interfere with the subsequent connection between the connecting tube and the positioning screw, thereby greatly improving the convenience of assembling the office desk.

[0021] Optionally, the support frame is provided with a sliding hole slidably connected to the connecting tube, and the limiting assembly includes: A buckle plate, the buckle plate is buckled and slidably arranged on the support frame; A pushing screw, wherein the pushing screw is threadedly connected to the support frame; A push plate is arranged on the push screw, the push plate is pressed against the support frame for positioning and causes the buckle plate and the sliding hole to be misaligned, or the push plate passes through the sliding hole and then presses against the connecting tube and causes the limit ring to press against the ground for positioning.

[0022] By adopting the above technical solution, when locking is required, the connecting tube is removed from the sliding hole, the limiting ring is facing downward to the ground and the connecting tube is extended into the sliding hole, the buckle plate is moved to align with the sliding hole, and the push screw is turned to drive the push plate close to the connecting tube. The push plate pushes the connecting tube and the limiting ring close to the ground, so that the limiting ring is pressed against the ground, and the limiting ring increases the contact area with the ground, thereby improving the positioning effect, and the connecting tube is extended into the sliding hole, so that the internal thread of the connecting tube can be protected.

[0023] When unlocking, turn the push screw to drive the push plate to disengage from the sliding hole, then move the buckle plate and the sliding hole to be misaligned, turn the push screw to drive the push plate to press against the support frame for positioning, and then you can remove the connecting tube, with the limit ring facing upwards, slide the connecting tube onto the sliding hole, thereby improving the positioning effect of the support frame and the connecting tube.

[0024] Optionally, the buckle plate is provided with a fixing hole which is slidably connected to the connecting tube and enables the push plate to be aligned with the sliding hole.

[0025] By adopting the above technical solution, the connecting tube is slidably installed in the fixing hole and then extends into the sliding hole, so that the push plate is aligned with the fixing hole, making it easier for the push plate to extend into the sliding hole, thereby improving convenience during operation.

[0026] Optionally, the limiting component includes: A limiting screw, wherein the limiting screw is threadedly connected to the support frame; A limiting nut, wherein the limiting nut is threadedly connected to the limiting screw, and the connecting tube can be threadedly connected to the limiting screw for placement, and the limiting nut is pressed against the supporting frame to position the limiting screw, or the limiting nut is pressed against the connecting tube and the connecting tube rotates to drive the limiting screw to rotate; The limiting plate is arranged on the limiting screw and is pressed against the ground for support and positioning. The limiting screw rotates to drive the limiting plate closer to or away from the ground.

[0027] By adopting the above technical solution, when the support frame needs to be supported on the ground, the connecting tube is disengaged from the positioning screw, and then the connecting tube is removed from the support frame, and then the connecting tube is threadedly connected to the limiting screw, so that the connecting tube is pressed against the limiting nut for positioning, and the connecting tube can be driven to rotate by continuing to rotate the limiting screw. The rotation of the limiting screw drives the limiting plate to approach and press against the ground for positioning, and finally the limiting nut is turned to approach the support frame and press against the support frame for positioning. Therefore, the connecting tube can drive the limiting screw to rotate, which improves the convenience of positioning the support member and facilitates the placement of the connecting tube. At the same time, the connecting tube can protect the thread of the limiting screw, which greatly reduces the probability of damage to the limiting screw and further reduces the probability of injury to people after collision with parts of the human body.

[0028] When unlocking is required, the limit nut is turned close to and pressed against the connecting tube, and the limit nut is continued to be turned to drive the limit screw to rotate, so that the limit plate is away from the ground, thereby unlocking the support frame position.

[0029] Optionally, a rubber pad for increasing friction is provided at the bottom of the limiting plate.

[0030] By adopting the above technical solution, the positioning effect is improved.

[0031] Optionally, an elastic protective sleeve is provided on the outer side wall of the connecting tube.

[0032] By adopting the above technical solution, the protective sleeve can facilitate the use of force when rotating the connecting tube, thereby improving the convenience of rotating the connecting tube. The protective sleeve can also provide cushioning when colliding with parts of the human body, thereby greatly reducing the safety of the office desk when in use.

[0033] Optionally, the rotating assembly includes: A fixed plate, the fixed plate is arranged on the auxiliary table and is provided with a rotating rod; The rotating member is arranged on the mounting plate and is rotatably connected with the rotating rod.

[0034] By adopting the above technical solution, the fixed plate is fixedly installed on the lower surface of the sub-table, and the fixed plate does not need to be removed during transportation, so a variety of connection methods can be added, such as glue plus screws to improve the firmness of the connection, and the rotating plate is fixedly installed on the mounting plate and rotatably connected to the rotating rod, thereby further improving the strength when connected to the sub-table and improving the stability of the office desk when in use.

[0035] Optionally, the rotating member is detachably connected to the mounting plate via screws.

[0036] By adopting the above technical solution, the rotating part and the mounting plate are made of metal materials, and therefore will not be easily damaged due to the soft material. Therefore, the rotating part and the mounting plate are detachably connected by screws. When the fixed plate is fixedly installed on the sub-table, the mounting plate and the rotating part are disassembled, and then the connection between the fixed plate and the sub-table can be conveniently achieved, which improves the convenience during installation and the convenience of assembly.

[0037] In summary, the present application includes at least one of the following beneficial technical effects: During the transportation process, multiple main tables are transported together, and the support frame is rotated and connected with the installation rod for transportation, thereby reducing the space occupied by the transportation of the auxiliary table.

The size of the mounting hole 12 is opened according to needs, and only one mounting hole 12 is required, which makes the main table 11 more beautiful; at the same time, during transportation, the supporting mechanism 5 and the rotating mechanism 2 are connected to each other for positioning, so that the sub-table 13, the rotating mechanism 2 and the supporting mechanism 5 can be placed together for transportation, thereby reducing the probability of parts being lost during transportation and affecting subsequent assembly.

[0043] The rotating mechanism 2 and the supporting mechanism 5 are respectively located at the two ends of the sub-table 13 in the length direction. The main table 11 forms a storage space for placing items, and the mounting hole 12 passes through the desktop of the main table 11 and extends into the storage space; the rotating mechanism 2 includes a mounting plate 21, a positioning component 3 and a rotating component 4. The mounting plate 21 is set on the desktop of the main table 11, and a mounting rod 22 in a vertical state is fixedly installed on the lower surface of the mounting plate 21. The mounting rod 22 is vertically inserted downward into the mounting hole 12, and the bottom end of the mounting rod 22 is located in the mounting hole 12.

A rotating column 23 in a horizontal state is fixedly installed at the bottom of the mounting rod 22, and the axis of the rotating column 23 is perpendicular to the length direction of the sub-table 13; the top of the positioning screw 31 is rotatably installed on the rotating column 23 and the diameter of the positioning screw 31 is smaller than the diameter of the mounting rod 22, and the bottom of the positioning screw 31 extends vertically downward into the storage space, and at the same time, the axes of the positioning screw 31, the mounting rod 22 and the mounting hole 12 coincide; the positioning nut 32 is threadedly connected to the positioning screw 31 and pressed against the side wall of the storage space, so that the mounting plate 21 and the positioning nut 32 are respectively pressed against the opposite side walls of the main table 11 for positioning.

[0045] Reference Figure 1 and Figure 2 The rotating component 4 is arranged on the mounting plate 21 and is connected to the sub-table 13 to realize the rotating connection between the sub-table 13 and the main table 11. The rotating component 4 includes a fixed plate 41 and a rotating member 42. The fixed plate 41 is fixedly mounted on the lower surface of the sub-table 13, and the fixing method of the fixed plate 41 can be screws and / or glue. At the same time, the fixed plate 41 does not need to be removed later, so only the firmness needs to be considered, and there is no need to consider the ease of removal, thereby improving the firmness of the connection; a rotating rod 45 is fixedly mounted on the lower surface of the fixed plate 41, and the axes of the rotating rod 45 and the mounting hole 12 coincide.

[0046] The rotating member 42 includes a rotating tube 43 and a bearing 44. The rotating tube 43 is fixedly mounted on the upper surface of the mounting plate 21 by screws, so that the rotating tube 43 and the mounting plate 21 can be detached, and the axes of the rotating tube 43 and the rotating rod 45 coincide with each other. The bearing 44 is coaxially fixedly mounted on the inner wall of the rotating tube 43, and the rotating rod 45 is fixedly mounted in the bearing 44, so that the fixing plate 41 is rotatably connected to the mounting plate 21, thereby making the auxiliary table 13 and the main table 11 rotatably connected; at the same time, a plurality of ball bearings can be arranged on the upper surface of the rotating tube 43, and the ball bearings rest on the lower surface of the auxiliary table 13 for support and positioning.

[0047] Reference Figure 1 and Figure 2 The supporting mechanism 5 includes a mounting seat 51, a supporting frame 52 and a connecting assembly 6. The mounting seat 51 is fixedly installed on the lower surface of the end of the sub-table 13 away from the rotating mechanism 2, and the fixing method of the mounting seat 51 is the same as the fixing method of the fixing plate 41, and only the firmness needs to be considered without considering the ease of removal; two mounting seats 51 are arranged at intervals along the width direction of the sub-table 13, and a horizontal rotating shaft 14 is fixedly installed on the two mounting seats 51, and the axis of the rotating shaft 14 is parallel to the axis of the rotating column 23.

[0048] Reference Figure 1 and Figure 3 The support frame 52 includes two vertical rods 53 and a connecting rod 54. The top ends of the two vertical rods 53 are rotatably mounted on two rotating shafts 14 respectively, and the bottom ends of the two vertical rods 53 are vertically arranged downward. The rotating mechanism 2 is located between the two vertical rods 53 and has the same distance as that between the two vertical rods 53; the connecting rod 54 is fixedly mounted on the side wall on the opposite side of the bottom ends of the two vertical rods 53.

[0049] The connecting component 6 is arranged on the connecting rod 54 and is used to connect with the positioning screw 31. A positioning block 56 is fixedly installed at the bottom of the mounting seat 51 and on the side of the rotating shaft 14 away from the positioning screw 31. During transportation, the two vertical rods 53 are in a horizontal state and are connected to the positioning screw 31 through the connecting component 6. During installation, the connecting component 6 is unlocked, and the two vertical rods 53 are rotated to move closer to the positioning block 56, so that when the two vertical rods 53 are in a vertical state, the bottom is supported on the ground for positioning, and at the same time, the vertical rods 53 are positioned against the positioning block 56, so that the two vertical rods 53 cannot continue to rotate.

[0050] The vertical rod 53 rotates away from the positioning block 56 and approaches the positioning screw 31, and the positioning screw 31 rotates close to the vertical rod 53, so that the vertical rod 53 and the positioning screw 31 are both turned to a horizontal state. At this time, the support frame 52 and the positioning screw 31 are both placed parallel to the sub-table 13, and then the connecting component 6 is started to connect the connecting rod 54 with the positioning screw 31, so that the sub-table 13, the rotating mechanism 2 and the supporting mechanism 5 can be transported together; when installation is required, the connecting component 6 is unlocked, and then the rotating mechanism 2 is installed on the main table 11, and the vertical rod 53 is rotated at the same time so that the vertical rod 53 abuts against the positioning block 56 for positioning. At this time, the vertical rod 53 is in a vertical state and the bottom support is positioned on the ground, so that the sub-table 13 can be supported and positioned.

[0051] Reference Figure 1 and Figure 3 The connecting assembly 6 includes a connecting tube 61 and a limiting ring 62. The connecting tube 61 is a tubular structure. The axis of the connecting tube 61 is parallel to the length direction of the vertical rod 53, that is, the vertical rod 53 and the connecting tube 61 are both in a vertical state or a horizontal state. The following explanation is given when the connecting tube 61 is in a horizontal state. The connecting tube 61 slides along its own axis direction, that is, in a horizontal direction, and is penetrated on the connecting rod 54. The two ends of the connecting tube 61 are located on both sides of the connecting rod 54 and can be removed from the connecting rod 54. At the same time, a thread is provided in the connecting tube 61. When the vertical rod 53 and the positioning screw 31 are both in a horizontal state, the axes of the connecting tube 61 and the positioning screw 31 coincide, and the connecting tube 61 is pushed close to the positioning screw 31, and the threads of the connecting tube 61 and the positioning screw 31 are rotated and pressed against the positioning nut 32 for positioning.

[0052] The limit ring 62 is coaxially fixedly installed on the outer wall of the connecting tube 61 away from the end of the positioning screw 31, and the limit ring 62 is used to provide leverage when rotating the connecting tube 61; at the same time, when the bottoms of the two vertical rods 53 are supported on the ground, the bottom of the connecting tube 61 is supported on the ground under the action of gravity for positioning, and there is a certain distance between the limit ring 62 and the connecting rod 54; or, the limit ring 62 is placed on the connecting rod 54 for positioning under the action of its own gravity or the gravity of the connecting tube 61.

[0053] The working principle of the embodiment of the present application is as follows: Twist the positioning nut 32 to disengage it from the positioning screw 31, remove the mounting rod 22 and the positioning screw 31 from the mounting hole 12, then thread the positioning nut 32 onto the positioning screw 31, rotate the vertical rod 53 and the positioning screw 31 to a horizontal state, thread the connecting tube 61 onto the positioning screw 31 and press it against the positioning nut 32 for positioning, and then the sub-table 13, the rotating mechanism 2 and the supporting mechanism 5 can be transported together.

[0054] After being transported to the destination, twist the connecting tube 61 to disengage the positioning screw 31, turn the two vertical rods 53 to a vertical state, slide the connecting tube 61 through the connecting rod 54, remove the positioning nut 32 from the positioning screw 31, and pass the positioning screw 31 and the mounting rod 22 through the mounting hole 12 in sequence, so that the mounting plate 21 is set on the desktop of the main table 11. At the same time, the bottom of the vertical rod 53 is supported on the ground, and the positioning nut 32 is threadedly connected to the positioning screw 31 and pressed against the main table 11 for positioning, thereby reducing the probability of parts falling off during transportation and affecting assembly, improving the convenience of assembling and disassembling the office desk, and also improving the stability of the office desk during use, making the main table 11 more beautiful. Example

[0055] Reference Figure 1 , Figure 4 and Figure 5 The difference between this example and Example 1 is that universal wheels 55 are fixedly installed at the bottom of the two vertical rods 53 and below the connecting rod 54. The two universal wheels 55 roll on the ground to support and position the sub-table 13; a limiting assembly 7 is provided on the connecting rod 54. When the universal wheels 55 roll on the ground, the limiting assembly 7 is used to position the connecting tube 61 and the support frame 52.

[0056] A vertical sliding hole 57 is provided on the upper surface of the connecting rod 54, and the connecting tube 61 is vertically slidably installed on the sliding hole 57. A horizontal sliding groove 58 is provided on the side wall of the sliding hole 57; the bottom of the connecting tube 61 is supported on the ground for positioning, and the limit assembly 7 includes a limit block 81 and a limit screw 82. The limit block 81 is horizontally slidably installed on the sliding groove 58, and a limit surface that fits with the outer wall of the connecting tube 61 is provided on one end of the limit block 81 close to the connecting tube 61.

[0057] The limit screw 82 is horizontally threadedly connected to the side wall of the connecting rod 54 close to the mounting rod 22, and the limit screw 82 pushes the limit block 81 close to the connecting tube 61, so that the limit surface is pressed against the connecting tube 61 for positioning, thereby realizing the positioning of the connecting tube 61, and the connecting tube 61 is pressed against the ground to position the support frame 52, blocking the rotation of the two vertical rods 53; when unlocking is required, the limit screw 71 is turned away from the connecting tube 61, so that the connecting tube 61 can move freely, thereby realizing the unlocking of the connecting tube 61 and the support frame 52.

[0058] The working principle of the embodiment of the present application is as follows: The positioning screw 31 and the mounting rod 22 are passed through the mounting hole 12 in sequence, so that the mounting plate 21 is set up on the desktop of the main table 11, and the two vertical rods 53 are rotated to drive the two universal wheels 55 to roll and support on the ground. Then, the positioning nut 32 can be threadedly connected to the positioning screw 31 for positioning, and the connecting tube 61 is pushed downward to press against the ground. The limiting screw 71 is turned so that the limiting surface presses against the connecting tube 61 for positioning, thereby positioning the support frame 52 and the connecting tube 61. At the same time, the limiting screw 71 is turned away from the connecting tube 61 to unlock the connecting tube 61 and the support frame 52, thereby improving the convenience during assembly and disassembly of the office desk, and also improving the stability of the office desk when in use. Example

[0059] Reference Figure 6 , Figure 7 and Figure 8 The difference between this example and Example 2 is that: the limiting component 7 includes a snap-on plate 91, a pushing screw 92 and a push plate 93, the snap-on plate 91 is U-shaped and snap-on against the side wall and the upper and lower surfaces of the connecting rod 54, and a fixing hole 94 connected to the inner side of the snap-on plate 91 is opened on the lower surface of the snap-on plate 91, and the fixing hole 94 is in a vertical state; the pushing screw 92 is threadedly connected to the upper surface of the snap-on plate 91, and the push plate 93 is coaxially fixed on the bottom of the pushing screw 92, and the push plate 93 is pressed against the upper surface of the connecting rod 54 for positioning, or the push plate 93 extends into the sliding hole 57, and the axes of the push plate 93, the fixing hole 94 and the sliding hole 57 coincide, and the diameter of the fixing hole 94 is the same as the outer diameter of the connecting tube 61.

[0060] When it is necessary to position the support frame 52, the connecting tube 61 is removed from the sliding hole 57, the buckle plate 91 is moved to the sliding hole 57, the limiting ring 62 is downward and the connecting tube 61 is extended into the sliding hole 57 through the fixing hole 94, and then the pushing screw 92 is turned to drive the push plate 93 to extend into the sliding hole 57. The push plate 93 pushes the connecting tube 61 downward, so that the limiting ring 62 is pressed against the ground, thereby positioning the support frame 52 and the connecting tube 61. At the same time, relative to the connecting tube 61 pressing against the ground, the limiting ring 62 pressing against the ground can increase the contact area with the ground, and at the same time, the connecting tube 61 extending into the sliding hole 57 can protect the internal thread of the connecting tube 61.

[0061] When positioning is not required, turn the push screw 92 to drive the push plate 93 to move outside the sliding hole 57, move the buckle plate 91 to be misaligned with the sliding hole 57, turn the push screw 92 to make the push plate 93 press against the connecting rod 54 for positioning, and then remove the connecting tube 61 and pass it through the sliding hole 57 from above the connecting rod 54, so as to facilitate connection with the positioning screw 31, so that when the support frame 52 and the connecting tube 61 are positioned, the probability of slippage of the connecting tube 61 is reduced, which is convenient, fast and stable, and can protect the threads in the connecting tube 61, thereby improving the convenience of assembly and disassembly of the office desk, and also improving the stability of the office desk when in use.

[0062] The working principle of the embodiment of the present application is as follows: Remove the connecting tube 61 from the sliding hole 57, move the buckle plate 91 to the sliding hole 57, extend the connecting tube 61 through the fixing hole 94 into the sliding hole 57, then turn the push screw 92 to drive the push plate 93 to push the connecting tube 61 downward, so that the limiting ring 62 is pressed against the ground, thereby realizing the positioning of the support frame 52 and the connecting tube 61. When positioning is not required, turn the push screw 92 to drive the push plate 93 to move outside the sliding hole 57, move the buckle plate 91 to be misaligned with the sliding hole 57, turn the push screw 92 to make the push plate 93 press against the connecting rod 54 for positioning, and then remove the connecting tube 61 and pass it through the sliding hole 57 from above the connecting rod 54, so as to facilitate connection with the positioning screw 31, so that when the support frame 52 and the connecting tube 61 are positioned, the probability of slippage of the connecting tube 61 is reduced, which is convenient, fast and stable, and can protect the threads in the connecting tube 61, thereby improving the convenience of assembly and disassembly of the office desk, and also improving the stability of the office desk when in use. Example

[0063] Reference Figure 1 , Fig. 9 and Fig.10 The difference between this example and Example 2 is that the limiting assembly 7 includes a limiting screw 71, a limiting nut 72 and a limiting plate 73. The following is an explanation taking the vertical rod 53 in a vertical state as an example. The limiting screw 71 vertically passes through the upper surface of the connecting rod 54 and extends to the bottom of the connecting rod 54, and the limiting screw 71 can be threadedly connected to the connecting tube 61. At the same time, after the connecting tube 61 is separated from the positioning screw 31, the connecting tube 61 can be removed and threadedly connected to the limiting screw 71; an elastic protective sleeve 63 is provided on the outer wall of the connecting tube 61, which is convenient for holding during rotation, and the protective sleeve 63 can also provide buffering when in contact with the body.

[0064] The limiting nut 72 is threadedly connected to the limiting screw 71 and is located above the connecting rod 54. The limiting nut 72 presses against the connecting tube 61 so that the connecting tube 61 rotates and drives the limiting screw 71 to rotate, or the limiting nut 72 presses on the upper surface of the connecting rod 54 to position the limiting screw 71; the limiting plate 73 is coaxially fixedly installed at the bottom of the limiting screw 71, and the rotation of the limiting screw 71 drives the limiting plate 73 to press against the ground for positioning; a rubber pad for increasing friction is fixedly installed on the lower surface of the limiting plate 73.

[0065] When it is necessary to position the support frame 52, the connecting tube 61 is threadedly connected to the limit screw 71 and pressed against the limit nut 72 for positioning, and the connecting tube 61 is continued to be rotated. Due to the limitation of the limit nut 72, the limit screw 71 is driven to rotate, so that the limit plate 73 is pressed against the ground for positioning, and finally the limit nut 72 is screwed to press against the connecting rod 54 for positioning, and the connecting tube 61 can be turned to continue to move closer to the limit nut 72 for positioning; when it is necessary to unlock, the connecting tube 61 is screwed away from the limit nut 72, and then the limit nut 72 is screwed to press against the connecting tube 61, and the limit nut 72 is continued to be rotated. Due to the positioning of the connecting tube 61, the limit screw 71 is driven to rotate, so that the limit plate 73 moves up and away from the ground, thereby achieving unlocking.

[0066] The working principle of the embodiment of the present application is as follows: When transportation is required, screw the connecting tube 61 away from the limiting nut 72, screw the limiting nut 72 to press against the connecting tube 61 and continue to rotate to drive the limiting plate 73 to disengage from the ground, remove the connecting tube 61 from the limiting screw 71 and slide it onto the connecting rod 54, and at the same time, screw the positioning nut 32 to disengage from the positioning screw 31, remove the mounting rod 22 and the positioning screw 31 from the mounting hole 12, and then thread the positioning nut 32 to the positioning screw 31, rotate the vertical rod 53 and the positioning screw 31 to a horizontal state, thread the connecting tube 61 to the positioning screw 31 and press against the positioning nut 32 for positioning, and then the sub-table 13, the rotating mechanism 2 and the supporting mechanism 5 can be transported together.

[0067] After being transported to the designated position, the connecting tube 61 is twisted to disengage the positioning screw 31, the connecting tube 61 is threadedly connected to the limiting screw 71 and pressed against the limiting nut 72 for positioning, the positioning nut 32 is removed from the positioning screw 31, the positioning screw 31 and the mounting rod 22 are passed through the mounting hole 12 in sequence, so that the mounting plate 21 is erected on the desktop of the main table 11, and the vertical rod 53 is turned to a vertical state and the universal wheel 55 is rolled on the ground for support, the positioning nut 32 is threadedly connected to the positioning screw 31 and pressed against the main table 11 for positioning, the connecting tube 61 is twisted to drive the limiting plate 73 to press against the ground for positioning, and finally the limiting nut 72 is twisted to press against the connecting rod 54 for positioning, thereby reducing the probability of parts falling off during transportation and affecting assembly, improving the convenience during assembly and disassembly of the office desk, and also improving the stability of the office desk during use, making the main desk 11 more beautiful.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
