Description

Technical Field

[0001] The utility model generally relates to the technical field of tableware, and in particular to a table column expansion structure and tableware. Background Art

[0002] A lifting table is a table with an adjustable height, which is increasingly used in daily life and office. Traditional lifting tables usually use telescopic sleeve-type table legs. The upper end of the table legs is connected to the crossbeam at the bottom of the table board. A screw is set inside the table legs, and the screws in the legs on both sides are driven to slide through a worm gear mechanism to achieve the lifting of the table board. However, the adjustment range of traditional lifting tables is very limited due to the length and number of sections of the screw and sleeve.

[0003] In order to solve the above problems, the applicant has previously provided a lifting table (application number: 202310327610.1), including a lifting column, a table support and a driving mechanism, the lifting column is composed of a telescopic sleeve, and the telescopic sleeve includes an outer sleeve and at least one inner sleeve, and the table support is movably connected to the outer sleeve; the driving mechanism is configured to drive the lifting column to lift, and the table support moves with the outer sleeve and stays at a preset position when the lifting stops; compared with the traditional lifting table, the table support can be installed after adjusting the height from the ground according to the required installation position, so that the initial height of the table support is variable, so as to adapt to different lifting groups; when lifting, the inner sleeve does not move, and the driving mechanism drives the outer sleeve to lift, so that the table support can be installed at any position of the outer sleeve and can be lifted and lowered smoothly. In addition, the protruding part of the lifting column relative to the table is the column head, and the column head can be used as a connector for installing modular expansion parts, such as the upper end opening of the column head on the table bracket, and the side wall can be installed with expansion parts, so that the outer sleeve can be used for multiple purposes.

[0004] For example, the applicant previously provided a table connection structure (application number: 202320698883.2), the connection structure includes a sleeve with no covering at both ends, after the sleeve is inserted into the outer tube, the through hole on the sleeve and the positioning hole on the outer tube are screwed and fixed, and various external brackets can be connected to the sleeve. Therefore, not only the column head is decorated through the connection structure, but also various external brackets can be connected through the sleeve, expanding the function of the lifting table and improving its practicality.

[0005] However, the above scheme has the following problems: if the connecting structure is set as an integrated tubular sleeve, if the length of the column head exposed from the table top is long, the corresponding sleeve also needs to be made of a corresponding length, which not only makes it necessary to spend more materials and high cost to make the sleeve, but also the longer length of the sleeve makes it impossible to ensure the flatness and straightness of the sleeve surface when making the sleeve, which will cause the sleeve to be unable to be sleeved on the column head, making the production and installation operations of the sleeve more inconvenient. Summary of the invention

[0006] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a pillar expansion structure and table furniture, which, by setting the peripheral structure as a split structure and installing it on the front, rear end and top surface of the pillar respectively, not only serves to decorate the pillar, but also consumes less material in manufacturing, thus saving costs; after installation, the middle parts of the left and right sides of the pillar are exposed, so that there is no need to consider the flatness and straightness of the peripheral structure during installation, thereby making the production and installation operations of the peripheral structure more convenient.

[0007] The effect of the utility model is achieved in this way:

[0008] In a first aspect, the present application provides a pillar expansion structure, including a pillar and a peripheral structure, the peripheral structure including a front baffle and a rear baffle respectively connected to the front and rear end surfaces of the pillar, and a top plate covering the top of the pillar, the front baffle and the rear baffle are both detachably arranged on the pillar, and the middle parts of the left and right sides of the pillar are exposed to the peripheral structure.

[0009] Furthermore, the rear baffle includes a cable management plate, the middle portion of which is bent to form a cable management groove extending in the vertical direction, and a first cable routing hole is provided on the rear end surface of the column, the first cable routing hole and the cable management groove are connected. The line passing through the top of the column can be passed through the first cable routing hole into the cable management groove and then connected to the socket on the rear side of the table, so that the line in the column will not be exposed to the table, thereby improving the overall aesthetics of the table.

[0010] Furthermore, the rear baffle also includes a connecting plate, one end of which is connected to the platform column, and the other end of which is connected to the cable management plate and the external bracket. By arranging the connecting plate to support the cable management plate and the external bracket, the load on the platform column is reduced, and the platform column is prevented from bending and deforming due to excessive load.

[0011] Furthermore, the left and right sides of the front baffle are each extended backward with a first positioning portion, and the left and right sides of the rear baffle are each extended forward with a second positioning portion. When the peripheral structure is connected to the pillar, the left and right side walls of the pillar are clamped by the two first positioning portions and the two second positioning portions to facilitate positioning of the front baffle and the rear baffle on the pillar, thereby making the installation operation of the peripheral structure easier.

[0012] Furthermore, a digital display device is integrated on the front baffle, which expands the function of the platform column and improves its practicality.

[0013] Furthermore, a mounting groove is provided on the front baffle, the digital display device is installed in the mounting groove, a clearance opening is provided on the front end surface of the front baffle, the clearance opening is connected to the mounting groove, and the digital display device outputs images through the clearance opening.

[0015] Furthermore, the notch of the installation slot is located at the top of the front baffle, and when the top plate cover is arranged on the front baffle, the notch of the installation slot is covered by the top plate. The installation slot will not be exposed on the front baffle, thereby making the appearance of the front baffle more integrated and beautiful.

[0016] Furthermore, a connecting beam is connected to the rear end of the tailgate, and the connecting beam is configured to connect to an external bracket, so that the table can be connected to more external brackets, with more diverse functions and higher practicality.

[0017] Furthermore, the connecting beam is a hollow sheet metal part, and an extension part extends backward from the rear end of the top plate, and the extension part covers the top end of the connecting beam. By setting the connecting beam as a sheet metal part, not only the manufacturing cost of the connecting beam is lowered, but also the load of the connecting beam on the column is reduced.

[0018] Furthermore, the portion where the rear end of the column and the connecting beam meet is recessed downward to form a mounting portion. When the top plate is covered on the column, the top plate fits the mounting portion so that the top plate can be embedded in the hollow portion of the column and the connecting beam, thereby improving the connection strength between the top plate, the column and the connecting beam.

[0019] Furthermore, there are protruding clamps on the left and right sides of the top plate, and overlapping parts are recessed on the left and right walls of the pillars. When the top plate is covered on the pillars, the clamps overlap the overlapping parts. This improves the connection strength between the top plate and the pillars, so that when the top plate is embedded in the pillars, it is supported by the overlapping parts and will not sink into the pillars.

[0020] Furthermore, a hook is vertically arranged at the front end of the top plate, and a card interface for engaging with the hook is provided at the rear end of the front baffle, thereby further improving the connection strength between the top plate and the front baffle, and facilitating the assembly and disassembly of the top plate through the hook.

[0021] Furthermore, the front baffle and the rear baffle are connected to the platform column by means of threaded connection, which ensures the connection strength and facilitates the assembly and disassembly of the front baffle and the rear baffle.

[0022] In the second aspect, the present application provides a table, a table top, table legs and a column extension structure. The table is a lifting table. The table legs include an outer tube and an inner tube that are socketed with each other. The outer tube can slide up and down relative to the inner tube. The table top and the outer tube remain relatively fixed and the two are lifted and lowered synchronously. The part of the outer tube formed above the table top constitutes the column.

[0023] Furthermore, a connecting piece is embedded in the table top, and a mounting hole for connecting the table column is opened in the middle of the connecting piece, and the part of the connecting piece near the mounting hole is recessed downward to form a positioning groove, and when the table column is connected to the connecting piece, the lower ends of the front baffle and the rear baffle fit into the positioning groove, so that the lower ends of the front baffle and the rear baffle are not easy to swing left and right, and the stability of the connection between the front baffle and the rear baffle and the table column 1 is further improved.

[0024] In a third aspect, the present application provides a table set, including a table top, table legs, and a table column extension structure, wherein the table top and the table legs are relatively fixed, and the table column is a columnar component fixed to the top of the table top.

[0045] In this embodiment, by providing the first positioning portion 210 and the second positioning portion 330, when installing the peripheral structure, the front baffle 2 and the rear baffle 3 can clamp the left and right side walls of the pillar 1 through the protruding first positioning portion 210 and the second positioning portion 330, so as to facilitate positioning the front baffle 2 and the rear baffle 3 on the pillar 1, making the installation operation of the peripheral structure easier.

[0046] In some embodiments of the present application, a digital display device 5 is integrated on the front baffle 2. By integrating the digital display device 5, the user can use the digital display device 5 on the front baffle 2 as a secondary screen, which solves the problem that the user places a secondary screen on the desktop and occupies the desktop space, expands the function of the column 1, and improves practicality.

[0047] In some embodiments of the present application, a mounting groove 220 is provided on the front baffle plate 2, the digital display device 5 is installed in the mounting groove 220, a clearance opening 221 is provided on the front end surface of the front baffle plate 2, the clearance opening 221 is connected to the mounting groove 220, and the digital display device 5 outputs images through the clearance opening 221.

[0048] In this embodiment, the digital display device 5 is inserted into the front baffle 2 through the installation slot 220 , which not only makes the connection between the two more stable, but also makes the installation and removal operations of the digital display device 5 more convenient.

[0049] In some embodiments of the present application, the digital display device 5 includes a substrate and a display screen. The substrate is installed in the installation groove 220, and the display screen is installed on the front end surface of the front baffle 2. The display screen and the substrate are connected through an avoidance opening 221.

[0050] In this embodiment, if the digital display device 5 is a split structure, the installation can be completed by inserting the base plate into the installation groove 220 and then installing the display screen on the front end surface of the front baffle 2, which ensures the connection strength while making the loading and unloading operations more convenient.

[0051] In some embodiments of the present application, the notch of the mounting groove 220 is located at the top of the front baffle 2, and when the top plate 4 is covered on the front baffle 2, the notch of the mounting groove 220 is covered by the top plate 4. When the peripheral structure is installed on the column 1, the mounting groove 220 is covered by the top 4 and will not be exposed, thereby making the appearance of the front baffle 2 more integrated and beautiful.

[0052] In some embodiments of the present application, a connecting beam 340 is connected to the rear end of the tailgate 3 , and the connecting beam 340 is configured to be connected to an external bracket.

[0053] In this embodiment, by setting a connecting beam 340, the rear ends of the left and right columns 1 on the table are connected with connecting beams 340, and the two ends of the perforated board or the connecting frame can be connected to the two connecting beams 340 respectively, so that the table can be connected to more external brackets, with more diverse functions and higher practicality.

[0054] In some embodiments of the present application, the connecting beam 340 is a hollow sheet metal part, and an extension portion 410 extends backward from the rear end of the top plate 4 , and the extension portion 410 covers the top end of the connecting beam 340 .

[0055] In this embodiment, by setting the connecting beam 340 as a sheet metal part, not only the manufacturing cost of the connecting beam 340 is lowered, but also the load of the connecting beam 340 on the column 1 is reduced, thereby preventing the column 1 from bending due to excessive load.

[0056] Among them, the lower end of the connecting beam 340 is set at an angle, and the vertical length of the connecting beam 340 gradually decreases from the end connected to the pillar 1 to the rear, so that the weight borne by the connecting beam 340 can be dispersed through the inclined surface at the bottom, thereby improving the load-bearing capacity of the connecting beam 340.

[0057] In some embodiments of the present application, the portion where the rear end of the pillar 1 and the connecting beam 340 meet is recessed downward to form a mounting portion 341. When the top plate 4 is covered on the pillar 1, the top plate 4 fits the mounting portion 341, so that the top plate 4 can be embedded in the hollow portion of the pillar 1 and the connecting beam 340, thereby improving the connection strength between the top plate 4 and the pillar 1 and the connecting beam 340.

[0058] When the top plate 4 is embedded in the pillar 1 and the connecting beam 340 , the top plates 4 , the pillar 1 and the top ends of the connecting beam 340 are flush, thereby making the top end of the pillar 1 more flat and beautiful.

[0059] In some embodiments of the present application, a clamping head 401 protrudes from the left and right sides of the top plate 4, and a lap joint 102 is recessed on the left and right side walls of the pillar 1. When the top plate 4 is covered on the pillar 1, the clamping head 401 overlaps the lap joint 102.

[0060] In this embodiment, the clamping head 401 of the top plate 4 overlaps the overlapping portion 102, which improves the connection strength between the top plate 4 and the pillar 1, so that when the top plate 4 is embedded in the pillar 1, it is supported by the overlapping portion 102 and will not sink into the inside of the pillar 1.

[0061] In some embodiments of the present application, a hook 402 is vertically disposed at the front end of the top plate 4, and a card interface 201 is provided at the rear end of the front baffle 2 to engage with the hook 402. This further improves the connection strength between the top plate 4 and the front baffle 2, and also facilitates loading and unloading of the top plate 4 through the hook 402.

[0062] Among them, a screw connection part 403 is vertically arranged at the rear end of the top plate 4. When the top plate 4 is installed on the pillar 1, the screw connection part 403 at the rear end of the top plate 4 fits with the rear end of the connecting beam 340, and the two are fixed by a threaded connection, which further improves the connection strength between the top plate 4 and the connecting beam 340 and facilitates installation and disassembly.

[0063] In some embodiments of the present application, the front baffle 2 and the rear baffle 3 are connected to the column 1 by threaded connection. The peripheral structure and the column 1 are fixed by threaded connection, which ensures the connection strength and facilitates the loading and unloading of the front baffle 2 and the rear baffle 3.

[0064] The embodiment of the present application also provides a table set, including a table top 6, table legs 7 and a pillar extension structure as described above. The table set is a lifting table. The table legs 7 include an outer tube 103 and an inner tube 104 that are mutually socketed. The outer tube 103 can slide up and down relative to the inner tube 104. The table top 6 and the outer tube 103 remain relatively fixed and the two are lifted and lowered synchronously. The outer tube 103 protrudes upward above the table top 6. That is to say, the table top 6 is connected to the middle and upper part of the outer tube 103 by a connecting beam, and the part of the outer tube 103 formed above the table top 6 constitutes the pillar 1.

[0065] In this embodiment, the column expansion structure not only serves to decorate the column 1, but also allows various external brackets to be connected through the peripheral structure to expand the function of the lifting table and greatly improve the practicality of the lifting table.

[0066] In some embodiments of the present application, a connecting piece 610 is embedded on the table top 6, and a mounting opening 611 for connecting the table column 1 is opened in the middle of the connecting piece 610. The portion of the connecting piece 610 close to the mounting opening 611 is recessed downward to form a positioning groove 612. When the table column 1 is connected to the connecting piece 610, the lower ends of the front baffle 2 and the rear baffle 3 are fitted into the positioning groove 612.

[0067] In this embodiment, when the front baffle 2 and the rear baffle 3 are installed on the pillar 1, the lower ends are positioned by the positioning grooves 612, which further improves the stability of the connection between the front baffle 2 and the rear baffle 3 and the pillar 1, and avoids the lower ends from swinging left and right due to the excessive length of the front baffle 2 and the rear baffle 3.

[0068] The embodiment of the present application also provides a table set, including a table top 6, table legs 7, and a column extension structure. The table set is a fixed table, the table top 6 and the table legs 7 are relatively fixed, and the column 1 is a columnar component fixed to the top of the table top 6. Of course, the column 1 can be a part of the table leg 7. In this case, it is equivalent to the table leg 7 crossing the table top 6 and continuing to extend upward, and the part of the table leg 7 located above the table top 6 forms the column 1; of course, the column 1 may not be connected to the table leg 7. In this case, the column 1 is a separate component and is fixed separately above the table top 6. There are various fixing methods, which are not the focus of this utility patent. For a fixed table, when a column 1 for connecting an external bracket or for decorative purposes is provided on the table top 6, the column extension structure can still be adapted to the table set.
