[0013] A method for using a connecting rod linkage type bidirectional expansion office table, comprising the following steps of use: First step: unlock the extension desktop panel, unscrew the knob locking bolt on the extension desktop panel, so that it is separated from the screw hole on the side wall of the placing box, and the locking and fixing relationship between the extension desktop panel and the placing box is released, so that the subsequent expansion action is prepared; Second step: drive the extension drive assembly to rotate the drive part at the end of the placing box, and drive the drive lead screw shaft to rotate; since the drive lead screw shaft is threadedly connected with the drive plate, and the drive plate is respectively limited in the first sliding groove and the second sliding groove through the bottom drive block and the two end sliding blocks, the drive plate rotates along with the drive lead screw shaft and moves outward along the horizontal direction, and simultaneously drives the drive connecting plate and the bearing support plate on it to translate synchronously; Third step: when the drive connecting plate moves, it drives the translation and lifting assembly to extend outward and lift, and drives the two groups of articulated connecting rod plates to swing; the sliding column on the connecting rod plate first slides along the horizontal slot of the fixed plate (realizing horizontal guidance), and then enters the upward inclined inclined slot; under the guidance of the inclined slot, the connecting rod plate pushes the translation and lifting placing seat (originally placed on the bearing support plate) to translate outward from the placing box, and simultaneously lifts along the inclined direction, completing the translation and lifting linkage action; Fourth step: the desk adjustment assembly fine-tunes the position of the extension desktop panel, starts the adjustment motor on the mounting frame seat, drives the adjustment lead screw shaft to rotate; the articulated shaft connected with the adjustment lead screw shaft drives the first sliding block to slide along the first sliding rail of the mounting frame seat, and further drives the two groups of X-shaped scissor arms to deform; the X-shaped scissor arms cooperate with the second sliding block at the top and the second sliding rail at the bottom of the adjustment plate, drive the adjustment plate (linked with the extension desktop panel) to adjust the height and calibrate the horizontal posture, so that the extension desktop panel reaches the position suitable for use.

[0014] The above-mentioned at least one technical solution adopted by the embodiment of the present application can achieve the following beneficial effects: Firstly, the present application dynamically adapts to multiple scenarios and solves the contradiction between space and expansion; the connecting rod linkage type bidirectional expansion office table accurately responds to the core needs of modern office flexible switching and on-demand expansion, and completely solves the pain points of additional side tables and folding tables required by traditional fixed-size office tables. Through the bidirectional expansion design of the two ends of the office table body, the desktop area can be greatly expanded without additional auxiliary furniture, which not only meets the compact needs of single-person focused office, but also quickly adapts to large-area use scenarios such as temporary cooperation of multiple people, batch processing of files, and drawing unfolding. In the storage state, the expansion assembly is completely embedded in the placing box, and the overall volume is consistent with that of the traditional fixed table, without occupying additional office space, perfectly balancing the expansion demand and space saving, and adapting to various space layouts such as small offices and open office areas.

[0015] Secondly, the application simplifies the operation process, improves the adaptation accuracy and office continuity; in view of the defects of the traditional expandable office table (pull-out type, folding type) that the operation is complicated, the desktop is uneven after expansion, and the gap is obvious, the application realizes convenient and efficient expansion experience through the integrated structure of driving-linkage-adjustment. Only by loosening the locking bolt and rotating the driving hand disc, the translation and rising of the expansion assembly can be completed, and the fine adjustment and small-angle inclination adaptation of the expanded desktop can be realized by cooperating with the X-shaped scissor arm adjustment mechanism driven by the motor, so that the expanded desktop is flush with the body, and problems such as file jamming and poor writing are avoided. The whole process does not need to be manually disassembled, spliced or additionally fixed and supported, and one person can quickly complete the expansion-shrinkage switching, greatly improving the continuity and operation convenience of the office scene switching.

[0016] Thirdly, the application strengthens the structural stability, prolongs the service life and reduces the comprehensive cost; compared with the design defects of the traditional pull-out type expansion table that the single side slide rail is unevenly stressed and the folding type expansion table that the support is insufficient, the application adopts a composite stable structure of double sliding groove guide, connecting rod linkage and screw rod transmission, the driving and supporting assembly is uniformly stressed, and the bearing capacity is strong after expansion, which can stably support the weight demand of file stacking and office equipment placement, and avoid shaking and deviation during use. The locking structure connected by threads and the rubber pad built-in the expansion desktop panel not only guarantee the fixing reliability, but also buffer the collision, prevent scratching and sliding, and reduce the structure wear. The design of one table for multiple uses does not need enterprises to frequently replace office tables or plan additional cooperation space, which not only prolongs the service life of the application, but also reduces the procurement cost and space planning cost of office furniture, and takes into account the practicability and economy.

[0019] The following will describe in detail the technical scheme of the linkage linkage type bidirectional expansion office table and its use method provided by each embodiment of the present application in combination with the drawings.

[0020] Reference Figures 1 to 10As shown, the embodiment of the present application provides a connecting rod linkage type bidirectional expansion office table, which comprises an office table body 1, both ends of the office table body 1 are respectively provided with a placing box 10, the side wall of each placing box 10 is provided with a hinged expansion desktop panel 11, the expansion desktop panel 11 and the placing box 10 can be locked and fixed, the inside of each placing box 10 is provided with a desktop expansion mechanism 2, each desktop expansion mechanism 2 comprises an expansion drive assembly 20, a translation lifting assembly 21 and a desktop adjusting assembly 22, the expansion drive assembly 20 is in sliding fit with the placing box 10, the translation lifting assembly 21 is located inside the placing box 10, the expansion drive assembly 20 can drive the translation lifting assembly 21 to move out of the placing box 10, the desktop adjusting assembly 22 is located on the top of the translation lifting assembly 21, and the desktop adjusting assembly 22 can drive the expansion desktop panel 11 to adjust the position.

[0021] It should be noted that the office table body 1 is provided with a controller and a control button, which can control the expansion and contraction of the expansion desktop panel 11. In the use process, the office table body 1 is moved to a sufficient expansion space for use.

[0022] In the initial state, the office table body 1 is normally used: When the office table body 1 is not expanded, the expansion desktop panel 11 is in threaded connection with the side wall screw hole of the placing box 10 through the knob locking bolt 14, in a locked and fixed state, and is attached to the outside of the placing box 10; the translation lifting assembly 21 is fully accommodated in the inside of the placing box 10, and the translation lifting placing seat 210 is borne on the bearing branch plate 206 of the drive plate 200; the desktop adjusting assembly 22 is in a contraction state, ensuring that the overall structure is compact and does not occupy additional office space; the rubber pad 15 in the expansion desktop panel 11 is in a natural state, attached to the inside of the desktop, so as to normally use the office table body 1.

[0023] In specific embodiments, the expansion drive assembly 20 comprises a drive plate 200, a drive screw shaft 201, a drive part 202 and a drive connecting plate 203. The bottom of the placing box 10 is provided with a horizontally arranged first sliding groove 12. The two side walls of the placing box 10 are each provided with a second sliding groove 13. The bottom of the drive plate 200 is provided with a drive block 204. The drive plate 200 is slidably connected in the first sliding groove 12 through the drive block 204. The two ends of the drive screw shaft 201 are rotatably connected in the placing box 10, and the drive part 202 is located at the end of the drive screw shaft 201. The drive screw shaft 201 is threadedly connected with the drive plate 200. The two ends of the drive plate 200 are each provided with a sliding block 205. The two ends of the drive plate 200 are each slidably connected in the second sliding groove 13 through the two sliding blocks 205. The drive connecting plate 203 is vertically arranged on the drive plate 200. The drive plate 200 is provided with a bearing support plate 206.

[0024] It should be noted that the drive part 202 is an electric motor or a hand disc. In use, the drive screw shaft 201 can be automatically rotated by the electric motor or manually rotated by the hand disc.

[0025] When it is necessary to expand the desktop area, the knob locking bolt 14 is first manually loosened to release the fixation of the expansion desktop plate 11 and the placing box 10. Then, the drive part 202 is rotated to rotate the coaxially connected drive screw shaft 201. Since the drive screw shaft 201 is threadedly connected with the drive plate 200, and the drive plate 200 is slidably fitted in the first sliding groove 12 through the drive block 204 at the bottom and slidably fitted in the second sliding groove 13 through the sliding blocks 205 at the two ends, the rotational movement is converted into the linear sliding of the drive plate 200 in the horizontal direction. The drive plate 200 synchronously drives the vertically fixed drive connecting plate 203 to translate, thereby providing a power basis for the subsequent linkage. In this stage, the screw rod transmission and the double sliding groove guide ensure the smooth movement of the drive plate 200 and avoid the unilateral stress deviation.

[0026] In a specific embodiment, the translation and lifting assembly 21 comprises a translation and lifting placing seat 210, a fixed plate 211 and two connecting rod plates 212. The fixed plate 211 is horizontally arranged on the side wall inside the placing box 10, and is provided with a translation groove 213. The fixed plate 211 is located on the bearing support plate 206 when it is inside the placing box 10. One end of each of the two connecting rod plates 212 is hinged to the driving connecting plate 203, and the other end is hinged to the translation and lifting placing seat 210. One of the connecting rod plates 212 is provided with a sliding column 216 that is in sliding cooperation with the translation groove 213. The translation groove 213 is divided into a horizontal groove 214 and an inclined groove 215, which are connected. The inclined groove 215 is arranged upwardly inclined.

[0027] When the driving connecting plate 203 is translated, the two connecting rod plates 212 are driven to move through the hinge points. In the initial storage state, the sliding column 216 is located in the horizontal groove 214 of the translation groove 213. When the driving connecting plate 203 is translated outwardly, the connecting rod plate 212 pushes the sliding column 216 to slide along the horizontal groove 214, and drives the translation and lifting placing seat 210 to be translated synchronously outwardly from the placing box 10, so as to realize horizontal expansion. When the sliding column 216 slides to the connection between the horizontal groove 214 and the inclined groove 215, since the inclined groove 215 is designed upwardly inclined, when the connecting rod plate 212 continues to move, the sliding column 216 climbs upwardly along the inclined groove 215, and the translation and lifting placing seat 210 is lifted upwardly through the lever action of the connecting rod, so as to realize synchronous lifting. Finally, the translation and lifting placing seat 210 is completely moved out of the placing box 10, and the top is kept at an initial height that is approximately flush with the desktop of the office table body 1, which lays a foundation for subsequent precise adjustment.

[0028] In this stage, through the linkage of the connecting rod and the guidance of the groove, the integrated action of translation and lifting can be completed without additional manual operation, which solves the cumbersome problem of manual support of the traditional folding table.

[0029] In specific embodiments, the desktop adjusting assembly 22 comprises an adjusting plate 220, a mounting frame 221, an adjusting motor 222, an adjusting screw rod shaft 223, and two groups of X-shaped scissors arms 224. The mounting frame 221 is horizontally arranged on the translation and lifting placement seat 210 and is connected to the translation and lifting placement seat 210 by bolts. Two first supports 225 are arranged in the mounting frame 221 in a symmetrical manner. The adjusting screw rod shaft 223 is rotationally connected to the two first supports 225. The adjusting motor 222 is arranged on the first support 225 and is drivingly connected to the adjusting screw rod shaft 223. Two first sliding rails 226 are arranged on the mounting frame 221. First sliding seats 227 are slidingly arranged on the two first sliding rails 226. Two second sliding rails 228 are arranged on the bottom of the adjusting plate 220. Second sliding seats 229 are slidingly arranged on the two second sliding rails 228. The bottom ends of the two groups of X-shaped scissors arms 224 are hingedly connected to the mounting frame 221. The other ends of the bottom of the two groups of X-shaped scissors arms 224 are hingedly connected to the first sliding seats 227. The top ends of the two groups of X-shaped scissors arms 224 are hingedly connected to the adjusting plate 220. The other ends of the top of the two groups of X-shaped scissors arms 224 are hingedly connected to the second sliding seats 229. Hinge shafts 2290 are arranged on the first sliding seats 227 and are hingedly connected to the two groups of X-shaped scissors arms 224. The hinge shafts 2290 are threadedly connected to the adjusting screw rod shaft 223.

[0030] After the translation and lifting placement seat 210 is positioned, the extended desktop plate 11 is perfectly matched with the desktop of the main body by the desktop adjusting assembly 22. First, the adjusting motor 222 is started, and the output shaft drives the adjusting screw rod shaft 223 to rotate. The adjusting screw rod shaft 223 is threadedly connected to the hinge shafts 2290 of the first sliding seats 227, and the rotating motion is converted into the horizontal sliding of the first sliding seats 227 along the first sliding rails 226. When the first sliding seats 227 slide, the two groups of symmetrically arranged X-shaped scissors arms 224 are driven to extend and retract. The bottom ends of the X-shaped scissors arms 224 are hingedly connected to the mounting frame 221, and the other ends are hingedly connected to the first sliding seats 227. The top ends of the X-shaped scissors arms 224 are hingedly connected to the adjusting plate 220, and the other ends are hingedly connected to the second sliding seats 229. The second sliding seats 229 slide along the second sliding rails 228 at the bottom of the adjusting plate 220. The X-shaped scissors arms 224 drive the adjusting plate 220 to rise and fall, thereby finely adjusting the height of the extended desktop plate 11. At the same time, the symmetrical structure of the X-shaped scissors arms 224 ensures that the adjusting plate 220 is level, avoiding tilting. If different collaboration scenarios need to be adapted, such as placing drawings at an inclined angle, the extension and retraction amount of the scissors arms can be accurately controlled by the forward and reverse rotation of the adjusting motor 222, thereby achieving small-angle inclination adjustment of the extended desktop plate 11 to meet the needs of multi-element office work.

[0031] In a specific embodiment, the extension desktop panel 11 is provided with two threaded knob locking bolts 14, and the side wall of the placing box 10 is provided with screw holes for the threaded knob locking bolts 14.

[0032] In a specific embodiment, the extension desktop panel 11 is internally provided with a rubber pad 15; when the adjusting plate 220 contacts the extension desktop panel 11, the rubber pad 15 is contacted first, thereby protecting the extension desktop panel 11.

[0033] When the area needs to be extended, the following steps are performed: the threaded knob locking bolts 14 are loosened, the X-shaped scissor arms 224 are retracted by starting the adjusting motor 222, the adjusting plate 220 is lowered, the driving part 202 is rotated in the reverse direction, the driving plate 200 drives the driving connecting plate 203 to move inward, the connecting rod plate 212 pulls the slide column 216 to slide along the inclined groove 215 and then reset along the horizontal groove 214, the translating and rising placing seat 210 is retracted into the placing box 10, and finally the threaded knob locking bolts 14 are tightened, the extension desktop panel 11 is reattached to the placing box 10, and the initial compact state is restored.

[0034] A method for using a connecting rod linkage type bidirectional extension office table, comprising the following steps: First step: unlock the extension desktop panel 11, loosen the threaded knob locking bolts 14 on the extension desktop panel 11, so that they are separated from the screw holes in the side wall of the placing box 10, and the locking and fixing relationship between the extension desktop panel 11 and the placing box 10 is released, thereby preparing for the subsequent extension operation; Second step: rotate the driving part 202 at the end of the placing box 10 to drive the extension driving assembly 20 to rotate, thereby driving the driving screw shaft 201 to rotate; since the driving screw shaft 201 is threadedly connected with the driving plate 200, and the driving plate 200 is limited in the first sliding groove 12 and the second sliding groove 13 through the bottom driving block 204 and the two end sliding blocks 205, respectively, the driving plate 200 rotates along the horizontal direction to move outward of the placing box 10, and simultaneously drives the driving connecting plate 203 and the bearing support plate 206 on it to move synchronously; Third step: when the driving connecting plate 203 moves, it drives the translating and rising assembly 21 to extend outward and lift, thereby driving the two groups of connecting rod plates 212 to swing; the slide column 216 on the connecting rod plate 212 first slides along the horizontal groove 214 of the fixed plate 211 (to realize horizontal guidance), and then enters the upward inclined inclined groove 215; under the guidance of the inclined groove 215, the connecting rod plate 212 pushes the translating and rising placing seat 210 (originally placed on the bearing support plate 206) to move outward of the placing box 10, and simultaneously lifts in the inclined direction, thereby completing the linkage action of translation and rising; Fourth step: the desktop adjustment assembly 22 fine-tune the position of the extended desktop panel 11 start installation frame seat 221 on the adjustment motor 222, drive adjustment screw shaft 223 rotation; and adjustment screw shaft 223 threaded connection of articulated shaft 2290 drive the first sliding seat 227 along the first slide rail 226 of installation frame seat 221 sliding, in turn drive two groups of X type scissor arm 224 telescopic deformation; X type scissor arm 224 through the second sliding seat 229 of the top and the second slide rail 228 of the bottom of the adjustment plate 220 cooperation, drive adjustment plate 220 (with extended desktop panel 11 linkage) height adjustment and horizontal posture calibration, make the extended desktop panel 11 reach the position of adaptive use.

The bottom of the adjustment plate (220) is provided with two second slide rails (228), and the second slide rails (228) are provided with second slide blocks (229) that are slidably disposed. The bottom end of the two sets of X-shaped scissor arms (224) is hinged to the mounting frame (221), the other bottom end of the two sets of X-shaped scissor arms (224) is hinged to the first slide (227), the top end of the two sets of X-shaped scissor arms (224) is hinged to the adjusting plate (220), and the other top end of the two sets of X-shaped scissor arms (224) is hinged to the second slide (229). The first slide (227) is provided with a hinge shaft (2290) that is hinged to the two sets of X-shaped scissor arms (224). The hinge shaft (2290) is threadedly connected to the adjusting screw shaft (223).

6. A linkage-type bidirectional extendable desk according to claim 5, characterized in that: The extended desktop panel (11) is provided with two threaded knob locking bolts (14), and the side wall of the placement box (10) is provided with screw holes that are threadedly connected to the knob locking bolts (14).

7. A linkage-type bidirectional extendable desk according to claim 1, characterized in that: The extended desktop board (11) has a rubber pad (15) inside.

8. The method of using the linkage-type bidirectional extension desk according to any one of claims 1-7, characterized in that: The following usage steps are included: Step 1: Unlock the extension desktop panel (11) Loosen the knob locking bolt (14) on the extension desktop panel (11) to disengage it from the screw hole on the side wall of the placement box (10), thereby releasing the locking relationship between the extension desktop panel (11) and the placement box (10) and preparing for subsequent expansion actions; Step 2: Drive the extended drive assembly (20) to rotate the drive unit (202) at the end of the placement box (10), which drives the drive screw shaft (201) to rotate. Since the drive screw shaft (201) is threadedly connected to the drive plate (200), and the drive plate (200) is limited in the first slide groove (12) and the second slide groove (13) respectively by the bottom drive block (204) and the two end sliders (205), the drive plate (200) moves outward in the horizontal direction along with the rotation of the drive screw shaft (201), and at the same time drives the drive connecting plate (203) and the bearing support plate (206) on it to move synchronously. Step 3: When the drive connecting plate (203) moves, it drives the translation and lifting assembly (21) to extend outward and lift, causing the two sets of hinged connecting rod plates (212) to swing. The sliding column (216) on the connecting rod plate (212) first slides along the horizontal groove (214) of the fixed plate (211) to achieve horizontal guidance, and then enters the upward inclined groove (215). Under the guidance of the inclined groove (215), the connecting rod plate (212) pushes the translation and lifting placement seat (210) to move outward of the placement box (10) and lifts along the inclined direction at the same time, completing the translation and lifting linkage action. Step 4: The desktop adjustment component (22) fine-tunes the position of the extended desktop board (11). The adjustment motor (222) on the mounting frame (221) is started, driving the adjustment screw shaft (223) to rotate. The hinge shaft (2290) threadedly connected to the adjustment screw shaft (223) drives the first slide (227) to slide along the first slide rail (226) of the mounting frame (221), thereby driving the two sets of X-shaped scissor arms (224) to extend and retract. The X-shaped scissor arms (224) cooperate with the second slide rail (228) at the bottom of the adjustment plate (220) through the second slide (229) at the top, driving the adjustment plate (220) and the extended desktop board (11) to perform height adjustment and horizontal posture calibration, so that the extended desktop board (11) reaches the position suitable for use.
