Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a multi-purpose height-adjustable table. Background Technology

[0002] In modern office environments, employees' work styles are becoming increasingly diverse, ranging from prolonged sitting to frequent standing interactions. This frequent switching between sitting and standing postures creates a clear and urgent need for height-adjustable desks. Traditional fixed-height desks cannot meet this need, forcing employees to work in only one position for extended periods. This not only easily leads to physical fatigue but may also cause various health problems. Furthermore, when conducting group discussions or team collaborations, multiple desks may need to be joined together to provide a larger work platform. However, due to their fixed structure, traditional desks often cannot be extended, causing significant inconvenience for team collaboration. Employees are forced to work within limited desktop space, impacting work efficiency and collaboration effectiveness.

[0003] For example, patent document with patent application number 201920442231.6 and publication date of December 31, 2019 discloses an integrated office desk frame, which has an outer frame, an inner frame, an upper crossbar, a main crossbar, and a lower crossbar; the outer frame has an outer end bar and two outer bars diagonally connected to the two ends of the outer end bar; the inner frame has an inner end bar, two inner bars diagonally connected to the two ends of the inner end bar, and a top vertical bar vertically connected to the middle of the inner end bar, with a top bar end block at the top of the top vertical bar; an inner frame is provided between the two outer frames and is connected horizontally by two main crossbars in sequence, forming an office unit between the inner and outer frames; it has the characteristics of simple structure and stable and solid structure. Another integrated office desk is proposed, which includes the aforementioned desk frame. The office unit of the desk frame is provided with an upper shelf, a tabletop, and a lower shelf from top to bottom. The top of the office unit is equipped with a strip light. It has a certain degree of isolation while facilitating communication between office staff, and does not affect lighting, thus creating a bright, comfortable, and open office environment.

[0004] The above-mentioned desks without height adjustment on the outer frame cannot meet the needs of switching between sitting and standing postures. If the desktop height is adjusted via a drive mechanism, the desk legs need to be connected to the drive device, making the entire desk heavy and structurally complex. Furthermore, each office unit consists of an outer frame and an inner frame, and the structures of the outer and inner frames are different, requiring careful distinction between their connection methods and positions during installation. This not only increases the complexity of installation but may also lead to installation errors. Moreover, the outer frame in the above-mentioned documents cannot be spliced ​​outwards, making it impossible to add new office units according to actual needs. Summary of the Invention

[0005] This utility model provides a versatile height-adjustable table that is easy to adjust in height and has a simple structure.

[0006] To achieve the above objectives, the technical solution of this utility model is: a multi-application height-adjustable table, comprising one or more supports, each support including side frames, two side frames connected by a connecting component, a tabletop provided on two adjacent side frames, each side frame including a side connecting rod, two or more stop rods provided on the two side connecting rods, the two or more stop rods being spaced apart along the length direction of the side connecting rods, a limiting groove provided on the tabletop corresponding to the stop rod position, a limiting mechanism provided on the limiting groove, the limiting mechanism including a limiting plate and a locking member, the locking member passing through the limiting plate and connected to the tabletop, the limiting plate and the limiting groove forming a cavity, one end of the stop rod passing through the side connecting rod and being limited within the cavity.

[0007] The above configuration involves two side connecting rods connecting to form a side frame, and two side frames connecting to form a support. Each side connecting rod has two or more stop rods arranged along its length, resulting in eight stop rods on one support. Four stop rods are positioned on a horizontal plane. When a tabletop is placed on the support, the tabletop's limiting groove is placed on the corresponding stop rod. The limiting plate then abuts against the stop rod, and fasteners are passed through the limiting plate to connect with the tabletop. This design allows the limiting plate to confine the stop rods within the cavity and fix them to the tabletop, thus securing the tabletop. When the tabletop needs to be moved to one of the other four position levers, loosen the fasteners, remove the limiting plate, and then move the tabletop to the other four position levers. Similarly, place the limiting groove of the tabletop on the corresponding position lever, and then the limiting plate abuts against the position lever. Then, pass the fastener through the limiting plate and connect it to the tabletop to complete the height adjustment of the tabletop. When adjusting the height, only the tabletop needs to be moved, and the tabletop can be fixed to the side connecting rod by means of the position lever, the limiting plate, and the limiting part through the locking device. This makes the entire tabletop height adjustment mechanism simple in structure.

[0008] Furthermore, the gear lever is provided with gear positions on both sides, and the limiting plate includes a limiting portion, which includes two or more limiting notches, the width of which is smaller than the diameter of the gear position.

[0009] The above settings, including the width of the limiting notch and the diameter of the gear position, ensure that when the gear position is placed inside the limiting notch, the limiting notch can limit the gear position, preventing it from moving freely within the limiting notch, thereby limiting the horizontal movement of the tabletop.

[0010] Furthermore, the limiting plate also includes a locking part, which has two or more locking grooves, and a locking element is provided in each locking groove.

[0011] The above configuration provides a connection point for the locking mechanism with the locking groove, and the cooperation between the limiting notch and the stop part provides a preliminary limiting function. The cooperation between the locking mechanism and the locking groove further enhances the fixing effect, effectively preventing the tabletop from loosening in the vertical direction, and also effectively preventing the tabletop from accidentally moving or loosening due to external forces, thereby improving the safety of the office environment.

[0012] Furthermore, the tops of the two side connecting rods are connected by a first positioning rod, and the bottoms of the two side connecting rods are connected by a second positioning rod.

[0013] With the above configuration, the top and bottom of the two side connecting rods are connected by the first positioning rod and the second positioning rod respectively, thereby achieving a stable connection between the two side connecting rods and forming a side frame from the two independent side connecting rods.

[0014] Furthermore, the first positioning rod has two or more first positioning holes on both sides, and the second positioning rod has two or more second positioning holes on both sides.

[0015] In the above configuration, the first positioning hole and the second positioning hole are configured to provide connection positions for the first connecting rod and the second connecting rod.

[0016] Furthermore, the connecting assembly includes a first connecting rod and a second connecting rod, with the tops of the two side frames connected by the first connecting rod and the bottoms of the two side frames connected by the second connecting rod.

[0017] With the above configuration, the top and bottom of the two side frames are connected by a first connecting rod and a second connecting rod, respectively, thereby achieving a stable connection between the two side frames and forming an office unit from the two independent side frames. The second connecting rod also provides a leg support position for office workers.

[0018] Furthermore, the first connecting rod is connected to the first positioning hole, and the second connecting rod is connected to the second connecting hole.

[0019] The above configuration includes two or more first positioning holes on both sides of the first positioning rod and two or more second positioning holes on both sides of the second positioning rod, which facilitates the connection between the first connecting rod and the second connecting rod. The first positioning holes and the second positioning holes are located on both sides of the first positioning rod and the second positioning rod, respectively, which facilitates the splicing and extension of the first connecting rod and the second connecting rod to both sides, thereby facilitating the splicing of new office units.

[0020] Furthermore, a placement cavity is provided between the two first connecting rods, in which a flower trough box, a socket box, and an LED light box can be placed. A connection hole is provided at the top of the side connecting rod, through which the connection wires of the socket box and the LED light box can pass.

[0021] The above design, with its storage compartment, provides the desk with additional multifunctional space. Users can place flower troughs, socket boxes, or LED lightboxes inside the compartment according to their needs, offering versatile storage space that not only increases the desk's practicality but also enhances its aesthetics.

[0022] Furthermore, a shelf is provided on one side of the side frame.

[0023] The above settings allow for easy categorization and storage of items, providing additional storage space for the desk and further enhancing its practicality.

[0024] Furthermore, the connection points on both sides of the tabletop are designed with curved chamfers.

[0025] The above design features rounded corners on both sides of the tabletop. These rounded corners better fit the human arm, thus improving the comfort of office workers and preventing discomfort caused by contact with hard edges during long working hours. Attached Figure Description

Detailed Implementation

[0032] Example 1.

[0033] like Figure 1-5 As shown, a multi-purpose height-adjustable table includes one or more supports. The supports include side frames 2, and two side frames 2 are connected by a connecting component. A tabletop 5 is provided on two adjacent side frames 2. The side frames 2 include side connecting rods 21, and two or more stop rods 22 are provided on the two side connecting rods 21. The tabletop 5 is provided with a limiting groove 51 at the corresponding position of the stop rod 22. A limiting mechanism is provided on the limiting groove 51. The limiting mechanism includes a limiting plate 11 and a locking member 12. The locking member 12 passes through the limiting plate 11 and is connected to the tabletop 5. The limiting plate 11 and the limiting groove 51 form a cavity, and the stop rod 22 is placed in the cavity.

[0034] like Figure 1-2 As shown, the tops of the two side connecting rods 21 are connected by the first positioning rod 3, and the bottoms of the two side connecting rods 21 are connected by the second positioning rod 4. The tops and bottoms of the two side connecting rods 21 are connected by the first positioning rod 3 and the second positioning rod 4 respectively, thereby achieving a stable connection between the two side connecting rods 21, and thus forming a side frame 2 from the two independent side connecting rods 21.

[0035] The first positioning rod 3 has two or more first positioning holes 31 on both sides, and the second positioning rod 4 has two or more second positioning holes 41 on both sides. The first positioning holes 31 and the second positioning holes 41 are configured to provide a connection position for the first connecting rod 6 and the second connecting rod 7.

[0036] The connecting assembly includes a first connecting rod 6 and a second connecting rod 7. The tops of the two side frames 2 are connected by the first connecting rod 6, and the bottoms of the two side frames 2 are connected by the second connecting rod 7. The tops and bottoms of the two side frames 2 are connected by the first connecting rod 6 and the second connecting rod 7 respectively, thereby achieving a stable connection between the two side frames 2. This allows the two independent side frames 2 to form an office unit, and the second connecting rod 7 provides a leg support position for office workers.

[0037] The first connecting rod 6 is connected to the first positioning hole 31, and the second connecting rod 7 is connected to the second positioning hole 41. Two or more first positioning holes 31 are provided on both sides of the first positioning rod 3, and two or more second positioning holes 41 are provided on both sides of the second positioning rod 4, facilitating the connection of the first connecting rod 6 and the second connecting rod 7. The first positioning holes 31 and the second positioning holes 41 are located on both sides of the first positioning rod 3 and the second positioning rod 4, respectively, facilitating the splicing and extension of the first connecting rod 6 and the second connecting rod 7 to both sides. In this embodiment, two sets of first positioning holes 31 are provided on both sides of the first positioning rod 3, with two holes in each set. A first connecting piece 61 is provided at one end of the first connecting rod 6, and the first connecting piece 61 has two holes connected to the first positioning hole 41. A first mounting hole 611 is provided corresponding to a positioning hole 31. Screws are provided in the first mounting hole 611 and the first positioning hole 31 to fix the first connecting rod 61 to the first positioning rod 3. The first positioning rod 3 has a first positioning hole 31 on each side, so that the first connecting rod 61 can be installed on both sides of the first positioning rod 3 to form two sets of side frames. The connection relationship between the second positioning rod 4 and the second connecting rod 7 is the same as the connection relationship between the first positioning rod 3 and the first connecting rod 6. When it is necessary to splice a new office unit on one side of the two independent side frames 2, it is only necessary to insert another first connecting rod and second connecting rod into the first positioning hole 31 and the second positioning hole 41, so as to facilitate the splicing of the new office unit.

[0038] A placement cavity is provided between the two first connecting rods 6, which can hold a flower trough box 8, a socket box 9, and an LED light box box 10. A connection hole 211 is provided at the top of the side connecting rod 21, allowing the connection wires of the socket box 9 and the LED light box box 10 to pass through. The design of the placement cavity provides additional multifunctional space for the desk. Users can place the flower trough box 8, the socket box 9, or the LED light box box 10 in the placement cavity according to their needs, providing multifunctional storage space. Therefore, it not only increases the practicality of the desk but also enhances its aesthetics.

[0039] Side shelf 2 has a storage rack 1 on one side, which can conveniently classify and store items, providing extra storage space for the desk and further increasing the desk's practicality.

[0040] like Figure 3-4 As shown, gear lever 22 has gear parts 221 on both sides, and limiting plate 11 includes limiting part 112. Limiting part 112 includes two or more limiting notches 1120. The width of limiting notches 1120 is smaller than the diameter of gear part 221. That is, when gear part 221 is placed inside limiting notch 1120, limiting notch 1120 can fit with gear part 221, so that gear part 221 cannot move freely inside limiting notch 1120, thereby limiting the horizontal direction of table board 5.

[0041] The limiting plate 11 also includes a locking part 111, which is provided with two or more locking grooves 1111. The locking grooves 1111 are correspondingly provided with locking members 12. The locking grooves 1111 provide a connection position for the locking members 12. The cooperation between the limiting notch 1120 and the stop part 221 provides a preliminary limiting function, while the cooperation between the locking member 12 and the locking grooves 1111 further enhances the fixing effect, effectively preventing the tabletop 5 from loosening in the vertical direction, and also effectively preventing the tabletop 5 from accidentally moving or loosening due to external force, thereby improving the safety of the office environment.

[0042] like Figure 5 As shown, the limiting part 112 includes a first connecting plate 1121, a second connecting plate 1122, and a third connecting plate 1123 arranged in parallel. Both ends of the third connecting plate 1123 are connected to one end of the first connecting plate 1121 and one end of the second connecting plate 1122, respectively, so that the entire limiting part 112 forms a plate structure with a Z-shaped cross-section. The first connecting plate 1121 has one or more limiting notches 1121. The tabletop 5 has an upwardly recessed cavity on the side near the stop lever 22, and a limiting groove is provided at the entrance of the cavity. One end of the limiting plate 111 is connected to the bottom surface of the second connecting plate 1122 and... The side of the third connecting plate 1123 abuts against the limit plate 11, so that the limit plate 11 can hold one side of the limit part and fix it to the table 5 by the locking member 12 on the limit plate 11. The first connecting plate 1121 covers the cavity to form a cavity for accommodating the gear lever. In this embodiment, one end of the gear lever 22 is provided with a gear part 221, which is a bolt. The first connecting plate 1121 is provided with a limiting notch 1120 for accommodating the bottom part of the bolt. The top of the gear part 221 abuts against the inner side wall of the limiting groove, so that the gear part 221 can be limited in the horizontal direction by the limiting notch 1120.

[0043] The tabletop 5 has curved sides, which can better fit the human arm, thereby improving the comfort of office workers and preventing discomfort caused by contact with hard edges during long working hours.

[0044] The working principle of this utility model is as follows: Two side connecting rods 21 are connected to form a side frame 2, and two side frames 2 are connected to form a support. Two stop rods 22 are provided on the side connecting rods 21, that is, there are eight stop rods 22 on one support. Every four stop rods 22 are on the same horizontal plane. When it is necessary to place the table board 5 on the support, the limiting groove 51 of the table board 5 is placed on the stop rod 22 accordingly, and then the limiting plate 11 abuts against the stop rod 22. Then the fastener passes through the limiting plate 11 and connects with the table board 5, thereby completing the fixing of the table board 5. When it is necessary to move the table board 5 to another four stop rods 22, the fastener is loosened, the limiting plate 11 is removed, and then the table board 5 is moved to another four stop rods 22. Similarly, the limiting groove 51 of the table board 5 is placed on the stop rod 22 accordingly, and then the limiting plate 11 abuts against the stop rod 22. Then the fastener passes through the limiting plate 11 and connects with the table board 5, thereby completing the adjustment of the table board 5.
