[0008] Also includes:

[0009] A limiting mechanism is provided on the inner side of the limiting base to press the component and fix the office chair in a limited position.

[0010] A folding mechanism, located inside the assembly rack, is used for folding and storage, and provides a resting place for workers when unfolded.

[0011] A further improvement of the present invention is that the limiting mechanism includes a clamping plate and a limiting groove, a buffer column is fixedly installed on the top of the clamping plate, and the top of the buffer column is fixedly installed on the top of the inner cavity of the limiting groove.

[0012] A further improvement of this utility model is that: a spring-loaded post is fixedly installed on the top of the limiting base, and a slider is fixedly connected to the telescopic end of the spring-loaded post; the top of the slider is movably sleeved on the bottom of the desk.

[0013] A further improvement of the present invention is that the folding mechanism includes a first folding plate, a second folding plate, and a third folding plate, which are connected by hinges, and the left end of the first folding plate is movably connected to one side of the support frame.

[0014] A further improvement of this utility model is that: connecting frames are movably connected to both sides of the bottom of the assembly frame, and the connection between the connecting frames and the assembly frame is through a movable column; the top of the connecting frame is movably sleeved on the bottom of the right end of the third folding plate.

[0015] A further improvement of this utility model is that: movable plates are fixedly installed at the bottom of both ends of the second folding plate, a sliding groove is provided on the inner side of the movable plate, a sliding block is movably connected inside the sliding groove, a connecting rod is movably connected to the bottom of the sliding block, a supporting bottom column is movably connected to the other end of the connecting rod, and the top of the supporting bottom column is movably connected to the bottom of the movable plate.

[0018] 1. This utility model provides a modular office desk and chair. After the support frame is pulled out from inside the assembly frame, the folding plate can rotate around the hinge axis due to the hinge connection and gradually unfold. During the unfolding process, the right end of the third folding plate pulls the connecting frame, and the connecting frame rotates around the movable column to unfold and form a bottom support for it. At the same time, when the movable plate at the bottom of the second folding plate moves with the unfolding, the sliding block slides along the slide groove and drives the connecting rod to rotate, thereby pushing the support bottom column to lower and contact the ground, providing stable support for the second folding plate. Finally, the entire folding mechanism unfolds to form a stable resting surface, which meets the resting needs of the staff, and the safety of the resting surface is ensured by the coordinated support of various components.

[0019] 2. This utility model provides a modular office desk and chair. When each folding panel is in the folded storage state, the connecting shaft can be manually rotated to cause the gear shaft to mesh with one end of the bottom of the transmission plate. The rotation of the gear shaft will be converted into the linear motion of the transmission plate, which will drive the clamping plate to extend, thereby clamping and fixing each folding panel. This prevents the panels from becoming loose or shifting due to accidental collisions or shaking during storage, ensuring the reliability of the folded storage state, making the assembly operation smoother and more efficient, and improving the convenience of the overall device for storage and assembly.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] like Figure 1-6 As shown, this utility model has the following three specific embodiments.

[0029] Example 1

[0030] This utility model provides a modular office desk and chair, including an office desk 1, an office display screen 2 movably installed on the top of the office desk 1, a limiting base 6 provided on the left side of the bottom of the office desk 1, an office chair 4 movably connected to the inner side of the limiting base 6, a storage cabinet 3 detachably installed on the left side of the inner cavity of the office desk 1, a pulley fixedly installed at the bottom of the storage cabinet 3, an assembly rack 5 fixedly installed on the right side of the inner cavity of the office desk 1, and a support frame 52 movably installed on the inner side of the assembly rack 5.

[0031] Also includes:

[0032] The limiting mechanism is located inside the limiting base 6 and uses a pressing component to limit and fix the office chair 4.

[0033] The folding mechanism, located inside the assembly rack 5, is used for folding and storage, and provides a resting place for staff when unfolded.

[0034] like Figure 1 As shown, the desk 1 is the basic load-bearing component of the overall assembly. The storage cabinet 3 on the left side of the desk 1's inner cavity is detachable, and the casters at the bottom allow for flexible movement. When the worker leaves the workstation, the handles at both ends of the office chair 4 engage with the limiting base 6. The clamping component makes close contact with the handles of the office chair 4 and applies pressure, using friction to restrict the office chair 4 from moving freely, thus achieving the function of limiting connection and preventing the office chair 4 from shifting. The folding mechanism is located inside the assembly frame 5 and is mainly used for folding and unfolding related components. When the rest function is not needed, the folding mechanism is in the folded state, effectively saving space in the inner cavity of the desk 1. When the worker needs to rest, the folding mechanism is operated to unfold it, at which point it will adjust to a suitable position, providing a temporary rest support structure to meet the worker's rest needs.

[0035] Example 2

[0036] The difference from Embodiment 1 is that this embodiment discloses a clamping plate 65, a first folding plate 53, a second folding plate 54, and a third folding plate 55. The limiting mechanism includes the clamping plate 65 and the limiting groove 63. A buffer post 64 is fixedly installed on the top of the clamping plate 65, and the top of the buffer post 64 is fixedly installed on the top of the inner cavity of the limiting groove 63. A spring-loaded post 62 is fixedly installed on the top of the limiting base 6. A slider 61 is fixedly connected to the telescopic end of the spring-loaded post 62. The top of the slider 61 is movably sleeved on the bottom of the desk 1. The folding mechanism includes a first folding plate 53, a second folding plate 54, and a third folding plate 55. The first folding plate 53, the second folding plate 54, and the third folding plate 55 are connected together. The components are connected by hinges. The left end of the first folding plate 53 is movably connected to one side of the support frame 52. The two sides of the bottom of the assembly frame 5 are movably connected to the connecting frame 51, and the connection between the connecting frame 51 and the assembly frame 5 is through the movable column. The top of the connecting frame 51 is movably sleeved on the bottom of the right end of the third folding plate 55. Movable plates 544 are fixedly installed at the bottom of both ends of the second folding plate 54. The inner side of the movable plate 544 is provided with a sliding groove. The sliding block 543 is movably connected inside the sliding groove. The bottom of the sliding block 543 is movably connected to the connecting rod 542. The other end of the connecting rod 542 is movably connected to the support base column 541. The top of the support base column 541 is movably connected to the bottom of the movable plate 544.

[0037] like Figure 2 , 3As shown in Figure 4, when the staff needs to rest, the handle of the office chair 4 slides into the inner side of the limiting base 6, and the clamping plate 65 is pressed against the buffer column 64. At this time, the rebound force of the buffer column 64 is used to make the clamping plate 65 fit tightly against the top of the handle of the office chair 4, achieving the function of clamping and fixing. At the same time, the slider 61 can slide at the corresponding position at the bottom of the desk 1, and then adapt to the position change by the extension and retraction adjustment of the rebound column 62, which is convenient for assembling office chairs 4 of different widths. Then the support frame 52 is pulled out from the inside of the assembly frame 5. Because of the first folding plate 53, the second folding plate 54, and the third folding plate 55, the support frame 52 is pulled out from the inside of the assembly frame 5. The folding plates 55 are connected by hinges. Each folding plate rotates around the hinge axis and gradually unfolds, with the support frame 52 providing basic support during unfolding. As unfolding occurs, the right end of the third folding plate 55 pulls down the connecting frame 51. The connecting frame 51 rotates around the movable column connected to the assembly frame 5, gradually unfolding from the folded state and forming bottom support for the right end of the third folding plate 55. Simultaneously, the movable plates 544 at the bottom of both ends of the second folding plate 54 move as the folding plate unfolds. The sliding blocks 543 in the inner grooves of the movable plates 544 slide along the grooves, causing the connecting rod 542 at the bottom to rotate. The support column 541, connected to the other end of the connecting rod 542, is lowered from the bottom of the movable plate 544 under the push of the connecting rod 542 until the bottom of the support column 541 touches the ground, providing stable support for the second folding plate 54. At this point, the entire folding mechanism unfolds to form a planar structure for resting. When folding is required, the folding plates are pushed in the opposite direction, and the components move along opposite trajectories, retracting and folding back into the assembly frame 5.

[0038] Example 3

[0039] The difference from Embodiment 2 is that this embodiment discloses a connecting shaft 524 and a gear shaft 525. The two ends of the support frame 52 are fixedly installed with fixing plates 521. The sides of the fixing plates 521 are fixedly installed with fixing blocks 522. The inside of the fixing blocks 522 is movably installed with a clamping plate 523. The bottom of the clamping plate 523 is fixedly connected with a transmission plate 526. One end of the bottom of the transmission plate 526 is engaged with the gear shaft 525. The inside of the gear shaft 525 is fixedly connected with a connecting shaft 524. The other end of the connecting shaft 524 is movably sleeved on the surface of the fixing block 522.

[0040] like Figure 5 , 6 As shown, when the first folding plate 53, the second folding plate 54, and the third folding plate 55 are folded and stored, the connecting shaft 524 is manually rotated to drive the gear shaft 525 to mesh with one end of the bottom of the transmission plate 526. The rotation of the gear shaft 525 is converted into the linear motion of the transmission plate 526, which causes the transmission plate 526 to drive the clamping plate 523 to extend and clamp and fix the first folding plate 53, the second folding plate 54, and the third folding plate 55, thereby facilitating the folding and assembly of the support frame 52 inside the assembly frame 5.

[0041] The working principle of this modular office desk and chair set will be explained in detail below.

[0042] like Figure 1-6 As shown, the desk 1 is the basic load-bearing component of the overall device. The storage cabinet 3 on the left side of the inner cavity of the desk 1 is detachable. The casters at the bottom give the storage cabinet the ability to move flexibly. When the staff leaves the workstation to rest, the handle of the office chair 4 slides into the inner side of the limiting base 6. The clamping plate 65 is pressed against the buffer column 64. At this time, the rebound force of the buffer column 64 makes the clamping plate 65 fit tightly against the top of the handle of the office chair 4, achieving the function of clamping and fixing. At the same time, the slider 61 can slide at the corresponding position at the bottom of the desk 1, and then adapt to the position change by the extension and retraction adjustment of the rebound column 62, which is convenient for assembling office chairs 4 of different widths. Then the support frame 5 2. Pull out from inside the assembly frame 5. Because the first folding plate 53, the second folding plate 54, and the third folding plate 55 are connected by hinges, each folding plate will rotate around the hinge axis and gradually unfold. The support frame 52 provides basic support for them during unfolding. As the unfolding process occurs, the right end of the third folding plate 55 pulls down the connecting frame 51. The connecting frame 51 rotates around the movable column connected to the assembly frame 5, gradually unfolding from the folded state, forming bottom support for the right end of the third folding plate 55. At the same time, the movable plates 544 at the bottom of both ends of the second folding plate 54 move as the folding plate unfolds. The sliding block 543 in the inner groove of the movable plate 544 will slide along the groove, driving the connecting rod 542 at the bottom to rotate. The support base column 541 connected to the other end of the connecting rod 542 is pushed down from the bottom of the movable plate 544 by the connecting rod 542 until the bottom of the support base column 541 touches the ground, providing stable support for the second folding plate 54. At this time, the entire folding mechanism unfolds to form a planar structure that can be rested. When storage is required, push the folding plate in the opposite direction, and each component will move along the opposite trajectory, retracting and folding back into the assembly rack 5.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
