Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a quick-install table leg. Background Art

[0002] In the prior art, utility model patent CN213154661U discloses a rotary quick-assembly table leg, comprising a table leg and a foot plate installed at the bottom of the table leg, a cover plate installed at the lower end of the table leg, and the cover plate is installed on the foot plate through a locking device; the locking device comprises a locking pin fixedly installed on the foot plate and a locking unit installed in cooperation with the locking pin, a lifting wedge is formed on the cover plate, when the column is rotated, the locking pin enters the locking hole through the positioning hole through the guide hole, and the lower end surface of the upper limit block enters the locking hole after being lifted by the lifting wedge, but there is no gap between the lifting wedge and the cover plate to provide space for the lifting wedge to deform, resulting in a large resistance to the lower end surface of the upper limit block being lifted by the lifting wedge, which makes the assembly of the table leg more difficult. Utility Model Content

[0003] The purpose to be achieved by the utility model is to provide a quick-install table leg, which solves the problem that the table leg assembly is relatively difficult, makes the table leg assembly simpler, and improves the installation efficiency of the table leg.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a quick-install table leg, including a column and a foot installed at the bottom of the column, the foot is provided with a mounting hole, two cantilevers are pre-installed in the mounting hole, the two cantilevers surround a locking hole position, an unlocking hole position connected to the locking hole position is provided in the mounting hole, a lifting inclined surface and an opening connecting the locking hole position and the unlocking hole position are provided on the cantilever, a locking piece is pre-installed on the column, the locking piece includes an end portion and a connecting portion provided on the end portion, when the connecting portion penetrates into the unlocking hole position and moves into the locking hole position, the end portion squeezes the cantilever and is interference fit with the lifting inclined surface to lock the foot onto the column.

[0005] After adopting the above technical scheme, the utility model has the following advantages: First, by combining the locking piece pre-installed on the column with the locking hole and the unlocking hole on the foot, the user only needs simple steps to complete the installation or disassembly of the table legs without the need for professional tools, which greatly improves the efficiency and reduces the difficulty of installation. Secondly, the cantilever has good deformation ability, so that the locking piece can easily enter the locking hole until it is completely locked, thereby improving the installation efficiency of the table legs, and also avoiding excessive squeezing of the locking piece, thereby ensuring the service life of the locking piece.

[0006] Furthermore, the cantilever protrudes from the surface of the foot so that the lifting slope is higher than the surface of the foot.

[0007] With the aforementioned technical solution, the protruding lifting slope design makes it easier for users to find and touch the lifting point during installation, without the need to take special effort to find or align the position, thereby simplifying the operation process and improving assembly efficiency.

[0008] Furthermore, the lifting slope includes an inclined section that guides the locking piece from the unlocking hole position to the locking hole position, a horizontal section that is interference fit with the end, and a transition section between the inclined section and the horizontal section, and the inclined section is located on the side of the lifting slope close to the unlocking hole position.

[0009] With the above technical solution, the segmented design makes the entire locking process smoother through step-by-step guidance, making the installation between the foot and the column easier. First, the inclined design of the inclined section can naturally guide the locking piece to slide from the unlocking hole to the locking hole. During the installation process, the user does not need to perform complicated alignment operations, but only needs to gently apply pressure along the guiding direction, which greatly simplifies the installation steps and improves the assembly efficiency. Secondly, the transition section serves as a bridge between the inclined section and the horizontal section, helping the locking piece to transition smoothly and ensure that it can be correctly aligned and fully contacted when reaching the horizontal section, avoiding misalignment or damage caused by direct hard impact, and improving the accuracy of installation. Finally, the interference fit between the horizontal section and the end ensures high stability in the locked state. This close fit can not only withstand greater vertical loads, but also effectively reduce the risk of loosening due to external forces, and enhance the stability and safety of the entire table leg.

[0010] Furthermore, the height of the highest point of the inclined section relative to the surface of the foot is L1, and the height of the horizontal section relative to the surface of the foot is L2, and L1≤L2.

[0011] With the above technical solution, if L1>L2, the end portion will get stuck when moving from the inclined section to the horizontal section, resulting in the inability to assemble continuously.

[0012] Furthermore, the cantilever and the base are integrally injection molded; or, further comprising a fixing plate detachably connected to the base, the mounting hole and the cantilever are arranged on the fixing plate.

[0013] By adopting the above-mentioned technical solution, the integrated design eliminates the connecting parts, reduces the potential weak links caused by the connecting points, enhances the structural strength between the cantilever and the column, and improves the stability and load-bearing capacity of the entire table leg; or, by setting a fixed plate, it is convenient to facilitate the separate processing of structures such as the lifting ramp, thereby avoiding the processing of structures such as the lifting ramp being affected by the material of the foot, etc. The detachable design also allows the user to replace or adjust the fixing plate as needed, thereby improving the adaptability and flexibility of the table legs and facilitating maintenance and upgrading.

[0014] Furthermore, the width of the opening is smaller than the diameter of the connecting portion so as to restrict the connecting portion from entering the unlocking hole position from the locking hole position.

[0015] By adopting the above-mentioned technical solution, the design in which the opening width is smaller than the diameter of the connecting part effectively limits the connecting part from accidentally moving from the locking hole position to the unlocking hole position under normal use, avoids the loose structure of the table leg due to unintentional operation, and enhances the reliability of the system.

[0016] Furthermore, the cantilever is provided at the edge of the opening with a guide surface for guiding the connecting part to enter the locking hole position from the unlocking hole position.

[0017] By adopting the above-mentioned technical solution, the design of the guide surface provides the user with a clear path indication, so that during installation or adjustment, the connecting part can easily slide into the locking hole along the guide surface without the need for complicated alignment actions, thereby simplifying the operation process and further improving installation efficiency.

[0018] Furthermore, the foot is also provided with an anti-dropping member which can be inserted into the unlocking hole to limit the locking member from moving from the locking hole into the unlocking hole.

[0019] By adopting the above-mentioned technical solution, the anti-slip component effectively prevents the accidental displacement of the locking component due to accidental collision or external force during use, thereby ensuring the stability and safety of the table leg structure.

[0020] Furthermore, a buckle that can extend into the locking hole through an opening is provided on one side of the anti-slip component close to the locking hole, and the buckle is clamped and fixed to the locking component.

[0021] The above-mentioned technical solution is adopted to realize the installation of the anti-dropping piece, thereby preventing the anti-dropping piece from falling off and ensuring that the anti-dropping piece plays an effective limiting role on the locking piece.

[0022] Furthermore, at least one locking member is provided, and the locking member is centrally symmetrically arranged about the center point of the column, and the foot is provided with locking holes and unlocking holes having the same number as the locking member.

[0023] By adopting the aforementioned technical solution, since the number of locking holes and unlocking holes corresponds one-to-one to the locking parts, the user can intuitively operate according to the position of each locking part during installation, avoiding the possibility of confusion and incorrect installation, simplifying the installation process, and improving efficiency. It can ensure that the force on the table legs in all directions is more balanced, further improving the installation reliability of the table legs. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0047] like Figures 1 to 13 As shown, the utility model provides a quick-install table leg, including a column 10 and a foot 20 installed at the bottom of the column 10, the foot 20 is provided with a mounting hole 41, two cantilevers 42 are pre-installed in the mounting hole 41, the two cantilevers 42 surround a locking hole 411, an unlocking hole 412 connected to the locking hole 411 is provided in the mounting hole 41, a lifting inclined surface 44 and an opening 45 connecting the locking hole 411 and the unlocking hole 412 are provided on the cantilever 42, a locking member 30 is pre-installed on the column 10, the locking member 30 includes an end portion 31 and a connecting portion 32 provided on the end portion 31, the diameter of the end portion 31 is smaller than the diameter of the unlocking hole 412 and larger than the diameter of the locking hole 411, and the diameter of the connecting portion 32 is smaller than the diameter of the locking hole 411 and the unlocking hole 412 at the same time. The diameter of the locking hole 412, when the connecting portion 32 passes through the unlocking hole 412 and moves into the locking hole 411, the end 31 squeezes the cantilever 42 and interferes with the lifting inclined surface 44 to lock the foot 20 on the column 10, which can effectively increase the stability of the table leg and prevent the table leg from shaking or loosening during use, thereby improving the user experience and safety. The pre-installed locking member 30, locking hole 411 and unlocking hole 412 do not require the user to use complex tools for assembly, and the user can quickly complete the assembly of the table leg. Secondly, the cantilever 42 has good deformation ability, so that the locking member 30 can easily enter the locking hole 411 until it is completely locked, thereby improving the installation efficiency of the table leg, and also avoiding excessive squeezing of the end 31 to ensure the service life of the locking member 30.

[0048] Since the foot 20 is usually made of metal, it is difficult to process structures such as the mounting hole 41 and the cantilever 42. For this reason, the present embodiment also includes a fixing plate 40 detachably connected to the foot 20. The fixing plate 40 is fixed to the foot 20 by a fastener 60, and the cantilever 42 is arranged on the fixing plate 40. By providing the fixing plate 40, the separate processing of structures such as the cantilever 42 is facilitated, thereby avoiding the processing of structures such as the lifting slope 44 that are affected by the material of the foot 20. The detachable design also allows the user to replace or adjust the fixing plate 40 as needed, thereby improving the adaptability and flexibility of the table legs and facilitating maintenance and upgrading.

[0049] To further facilitate assembly, the cantilever 42 protrudes from the surface of the foot 20 so that the lifting slope 44 is higher than the surface of the foot 20. Correspondingly, the cantilever 42 also protrudes from the surface of the fixing plate 40. The design of the protruding lifting slope 44 makes it easier for the user to find and contact the lifting point during installation without the need to take special effort to find or align the position, thereby simplifying the operation process and improving assembly efficiency.

[0050] Specifically, the lifting inclined surface 44 includes an inclined section 441 for guiding the locking member 30 from the unlocking hole position 412 to the locking hole position 411, a horizontal section 443 which is interference fit with the end portion 31, and a transition section 442 between the inclined section 441 and the horizontal section 443. The inclined section 441 is located on the side of the lifting inclined surface 44 close to the unlocking hole position 412. The inclined design of the inclined section 441 can naturally guide the locking member 30 to slide from the unlocking hole position 412 to the locking hole position 411, and the user does not need to perform complicated installation. The alignment operation only requires light pressure along the guide direction, which greatly simplifies the installation steps and improves the assembly efficiency. Secondly, the transition section 442 acts as a bridge between the inclined section 441 and the horizontal section 443, helping the locking member 30 to transition smoothly, ensuring that it can be correctly aligned and fully contacted when reaching the horizontal section 443, avoiding misalignment or damage caused by direct hard impact, and improving the accuracy of installation. Finally, the interference fit between the horizontal section 443 and the end face of the locking member 30 ensures high stability in the locked state. This close fit can not only withstand greater vertical loads, but also effectively reduce the risk of loosening caused by external forces, and enhance the stability and safety of the entire table leg.

[0051] In order to further facilitate the locking member 30 to enter the locking hole 411, the height of the highest point of the inclined section 441 relative to the surface of the foot 20 is L1, and the height of the horizontal section 443 relative to the surface of the foot 20 is L2, L1≤L2, making the process more natural. The user can easily complete the installation without special force or precise alignment, which simplifies the operation process.

[0052] In order to prevent the connection part 32 from being easily moved from the locking hole position 411 to the unlocking hole position 412 under the action of external force in normal use, in this embodiment, the width of the opening 45 is D1, and the diameter of the connection part 32 is D2, D1<D2, so as to limit the connection part 32 from entering the unlocking hole position 412 from the locking hole position 411, effectively limiting the connection part 32 from accidentally moving from the locking hole position 411 to the unlocking hole position 412 in normal use, avoiding the loosening of the table leg structure due to unintentional operation, and enhancing the reliability of the system.

[0053] Since the width of the opening 45 is smaller than the connecting portion 32, in order to facilitate the connecting portion 32 to enter the locking hole from the unlocking hole position 412, the cantilever 42 is located at the edge of the opening 45 and is provided with a guide surface 43 for guiding the connecting portion 32 to enter the locking hole position 411 from the unlocking hole position 412. The design of the guide surface 43 provides the user with a clear path indication, so that during installation or adjustment, the connecting portion 32 can easily slide into the locking hole position 411 along the guide surface 43 without complicated alignment actions, thereby simplifying the operation process and further improving the installation efficiency.

[0054] In order to further prevent the locking member 30 from loosening from the locking hole position and entering the unlocking hole position 412, the foot 20 is also provided with an anti-slip component 50 which can be inserted into the unlocking hole position 412 to limit the locking member 30 from moving from the locking hole position 411 to the unlocking hole position 412. The anti-slip component 50 effectively prevents accidental displacement of the locking member 30 due to accidental collision or external force during use, thereby ensuring the stability and safety of the table leg structure.

[0055] It should be noted that the anti-slip component 50 can be a plastic anti-slip plug with a certain deformation ability, which is convenient for installation into the locking hole 411.

[0056] Among them, an arc-shaped locking surface 51 is provided on the side of the anti-slip component 50 close to the locking hole 411, and the locking surface 51 is abutted and fit with the outer peripheral side surface of the locking component 30 located in the locking hole 411. The close fit between the locking surface 51 and the outer peripheral side surface of the locking component 30 forms an additional mechanical barrier, which can effectively prevent the locking component 30 from shifting along the unlocking hole 412 even under strong vibration or lateral force, thereby greatly reducing the risk of loosening or falling off due to accidents.

[0057] In order to install the anti-dropping member 50, a buckle 52 is provided on one side of the anti-dropping member 50 near the locking hole 411, which can be inserted into the locking hole 411 through the opening 45, and the buckle 52 is fixedly engaged with the locking member 30. Preferably, the buckle 52 is fixedly engaged with the end surface of the end portion 31 facing the lifting inclined surface 44, effectively preventing the anti-dropping member 50 from falling off, so that the anti-dropping member 50 can reliably prevent the locking member 30 from falling off.

[0058] In order to achieve the installation reliability of the table legs, at least one locking member 30 is provided, and the locking member 30 is symmetrically arranged about the center point of the column 10. The base 20 is provided with locking holes 411 and unlocking holes 412 which are the same in number as the locking members 30. Since the number of locking holes 411 and unlocking holes 412 corresponds one-to-one to the locking members 30, the user can intuitively operate according to the position of each locking member 30 during installation, thereby avoiding the possibility of confusion and incorrect installation, simplifying the installation process, and improving efficiency. It can ensure that the force on the table legs in all directions is more balanced, thereby further improving the installation reliability of the table legs.

[0059] Preferably, two locking members 30 are provided, and correspondingly, two locking holes 411 and unlocking holes 412 are provided on the foot 20 , and two anti-slip members 50 are provided.

[0060] When assembling, Figure 5 and Figure 6 As shown, two locking members 30 are pre-installed on the column 10, and a fixing plate 40 is pre-installed on the foot 20. The connecting parts 32 of the two locking members 30 on the column 10 are passed through the unlocking holes 412, and the foot 20 is attached to the surface of the column 10. Figure 7 and Figure 8 As shown, then, the two ends of the anchor 20 are rotated clockwise with force to make the locking member 30 enter the locking hole 411. At this time, the locking member 30 is resisted by the hole wall of the locking hole 411, and the anchor 20 cannot continue to rotate. At this time, the locking member 30 and the lifting inclined surface 44 are interference fit to fix the anchor 20 on the column 10. After installation, an anti-slip member 50 is inserted into the unlocking hole 412 to effectively prevent the anchor 20 from being loosened by force.

[0061] It can be understood that in other embodiments, the cantilever and the base are integrally injection molded, and the integrated design eliminates connecting parts, reduces potential weak links caused by connecting points, enhances the structural strength between the cantilever and the column, and improves the stability and load-bearing capacity of the entire table leg.

[0062] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
