Description

Technical Field

[0001] This invention relates to the field of furniture, and in particular to a table leg. Background Technology

[0002] In the table and height-adjustable table industry, the table legs are generally long, and the main body of the legs is perpendicular to the table feet. If an integrated fixed structure is used, the entire set of table legs will occupy a large packaging space, which will significantly increase the amount of packaging materials and the volume of the entire vehicle for transportation, resulting in high packaging and logistics costs for manufacturers, which is not conducive to the company's goal of reducing costs and increasing efficiency. In order to reduce the packaging volume, most existing table legs adopt a split structure in which the main body of the legs and the table feet can be detached, and rely on various connecting structures to achieve the assembly and fixation of the two.

[0003] Currently, most common table leg connection solutions on the market adopt two types of structures: screw locking and snap-fit ​​locking. The screw locking structure requires multiple screws for assembly, and consumers need to use screwdrivers and other tools to align and tighten them one by one. The disassembly and assembly steps are cumbersome, time-consuming, and the assembly experience is poor. On the other hand, although the ordinary snap-fit ​​connection structure does not require the assistance of tools, the snaps only rely on their own elasticity to achieve the limit, which has a weak load-bearing capacity. Moreover, the snaps are easy to come loose, which poses a safety hazard of table legs loosening and tipping over.

[0004] Furthermore, even if some disassembled table legs are equipped with locking mechanisms for installation, the structure controlling the movement of these mechanisms is quite complex, the locking operation is cumbersome, and the stability of the lock is difficult to guarantee. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a table leg comprising a detachably connected leg body and a table foot. Each leg is respectively provided with a connector with a locking groove, a rotatable actuator, and a movable locking component. The locking component and the actuator are linked by a linkage protrusion and a V-shaped linkage groove. The linkage groove is divided into a rapid movement section and a pressing section, located on either side of the actuator's rotation axis, with an interference point at the end of the pressing section. During assembly, after the connector is inserted, rotating the actuator drives the locking component to engage in the locking groove via the linkage groove, achieving rapid and stable locking. During disassembly, rotating the actuator in the opposite direction causes the locking component to disengage and unlock. This solution achieves rapid pressing and locking through a V-shaped segmented linkage groove, and the interference point forms an anti-loosening limit, ensuring stable locking and preventing loosening. This table leg can be quickly assembled and disassembled, with smooth and effortless operation, significantly reducing packaging and transportation volume and lowering costs.

[0006] The technical solution of this invention is implemented as follows:

[0007] A table leg includes a detachably connected leg body and a table foot. One of the table foot and the leg body has a connector with a locking groove. The other table foot and the leg body have a rotatable actuating member and a movable locking member, which are linked together. The table foot and the leg body are connected via the connector, and the rotation of the actuating member causes the locking member to enter the locking groove to lock the table foot and the leg body. The locking member has a linkage protrusion, and the actuating member has a linkage groove. The linkage protrusion is disposed in the linkage groove. When the actuating member rotates, the linkage protrusion and the linkage groove move relative to each other, causing the locking member to move towards or away from the locking groove. The linkage groove includes a connected rapid movement section and... In the clamping section, when the linkage protrusion moves toward the end of the rapid movement section, the locking member moves away from the locking groove; when the linkage protrusion moves toward the end of the clamping section, the locking member moves closer to the locking groove. When the linkage protrusion moves from the end of the rapid movement section to the end of the clamping section, the distance between the linkage protrusion and the rotation axis of the actuator increases. The linkage groove is V-shaped and inclined relative to the rotation axis of the actuator. The ends of the rapid movement section and the clamping section are located on both sides of the rotation axis of the actuator, respectively. There is an interference point near the end of the clamping section. The interference point is configured such that when the linkage protrusion passes through the interference point and is located at the end of the clamping section, the interference point stops the linkage protrusion from moving toward the end of the rapid movement section.

[0008] This solution allows for quick assembly and disassembly of the table legs and main body by rotating the actuator. During assembly, the table legs and main body are first connected via a connector, ensuring the locking groove on the connector is next to the locking element. Rotating the actuator then moves the linked locking element, inserting it into the locking groove for quick locking. Disassembly is simple: rotate the actuator in the opposite direction to disengage the locking element from the locking groove, then separate the table legs from the main body. Because this solution allows for quick assembly and disassembly, manufacturers can easily separate the two parts during packaging and transportation, significantly reducing costs and increasing efficiency. Consumers can also easily and quickly assemble the table legs and main body upon receiving the product, enhancing the user experience.

[0009] The linkage protrusion and linkage groove are linked to restrict the movement trajectory of the locking component through the trajectory of the linkage groove. The linkage groove always extends towards or away from the center of the actuating component between its two ends. Therefore, when it acts on the locking component, the locking component will always move in the radial direction of the actuating component, ensuring the smoothness of the locking component and ensuring different functions at different positions of the linkage groove. The linkage groove is V-shaped, so that the linkage groove and linkage protrusion are adapted to the rotation of the actuating component, and the two ends of the linkage groove provide different movement trajectories and functions. Although the linkage groove is V-shaped and has corners, its deflection arrangement on the rotation axis and the design of the fast movement section and the pressing section located on both sides of the rotation axis of the actuating component can take into account the direction of the linkage groove always moving away from or close to the rotation axis. The presence of the interference point can maintain the stability of the table legs and the main body when locked.

[0010] Preferably, the slope of the rapid movement section is greater than the slope of the pressing section in the direction approaching or moving away from the locking groove. The greater slope of the rapid movement section allows the linkage protrusion to quickly approach or move away from the rotation axis of the actuating member when moving on the rapid movement section, so that the locking member moves quickly towards or away from the locking groove.

[0011] Preferably, in the radial direction of the actuating element, the distance spanned by the rapid movement section is greater than the distance spanned by the pressing section. That is, the movement of the linkage protrusion in the linkage groove moves away from or towards the rotation axis of the actuating element, causing the locking element to move closer to or away from the locking groove. When the linkage protrusion moves in the rapid movement section, it can generate more radial displacement, thereby causing the locking element to generate more sliding displacement. When the locking element is directly subjected to external force and moves inward, the linkage protrusion and the linkage groove abut against each other. The greater the slope, the easier it is for the linkage protrusion and the linkage groove to generate relative movement, which may cause the locking element to disengage from the locking groove. Conversely, the smaller the slope, the less likely it is to generate relative movement. When it reaches the pressing section, the slope becomes gentler. Although the displacement generated is less, it can effectively prevent the linkage protrusion and the linkage groove from generating relative displacement, thus preventing the locking element from disengaging from the locking groove on its own.

[0012] Preferably, a stop bar protruding from the groove wall is provided at the interference point.

[0013] Preferably, the actuating element is disc-shaped or disc-shaped.

[0014] Preferably, the actuator has a drive hole, which is hexagonal. The actuator does not have a built-in operating part, thereby further reducing packaging space and preventing the operating part from protruding from the table leg; moreover, the drive hole is hexagonal, so the user can turn the actuator with an Allen wrench without the need for a special operating part.

[0015] Preferably, the locking element is slidably or rotatably disposed within the table leg. Sliding or rotating the locking element within the table leg allows for selective engagement between the locking element and the locking groove, enabling a more rational selection based on specific circumstances.

[0016] Preferably, the end of the locking member near the locking groove has a bevel, and the thickness of the locking member at the bevel increases from the outside to the inside. The bevel at the end of the locking member makes it easier for the locking member to enter the locking groove, and also allows for engagement even when the locking member and the locking groove are not fully aligned.

[0017] Preferably, two connectors are located at the bottom of the leg body and extend downwards. These two connectors are symmetrically arranged, with a mounting plate between them. Both ends of the mounting plate are fixedly connected to the two connectors. The number of locking components is the same as the number of connectors. The presence of two connectors and two locking components ensures a more stable connection between the table leg and the leg body. The connectors are plate-shaped, and both are simultaneously mounted to the bottom of the leg body via the mounting plate, simplifying the connection. The simpler structure of the connectors, located on the leg body while the locking and actuating components are integrated into the table leg, simplifies production and assembly. Furthermore, the leg body does not require additional space or slots that could compromise its strength.

[0018] Preferably, a mounting base is fixed on the table leg, and the actuator is rotatably mounted on the mounting base. A rack is also slidably mounted in the mounting base, and the outer contour of the actuator has meshing teeth that mesh with the rack. When the rack slides between the mounting base and the table leg, it drives the actuator to rotate, thereby driving the locking mechanism to move. The actuator can be driven to rotate by the sliding of the rack, thus eliminating the need for tools such as hex wrenches to disassemble or assemble the table legs.

[0019] Preferably, a control component is rotatably connected to the table leg. This control component is linked to the rack. When the control component rotates near the table leg, it causes the rack to slide and drives the locking component into the locking groove. The rack is controlled by the control component. To ensure a small packaging and transportation volume, the control component can rotate to be close to the table leg. When locking, the control component is also close to the table leg to prevent it from protruding and tripping the consumer.

[0020] Preferably, the table legs are provided with receiving grooves, and the control component is rotatably disposed in the receiving grooves. When the control component rotates into the receiving grooves, it drives the rack to slide and drives the locking component into the locking groove. Providing receiving grooves on the table legs for accommodating the control component further reduces the packaging and transportation volume, allowing the control component to directly enter the receiving grooves without protruding from the side of the table legs. Similarly, when locking is complete, the control component can also be located in the receiving grooves, making the surface of the table legs flat.

[0021] Preferably, the control component and the rack are connected by a guide groove and guide block structure or a connecting rod structure. This ensures that the rotation of the control component does not affect the sliding of the rack, allowing for smooth and seamless transmission.

[0022] The design starting point, concept, and beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0023] This solution allows for quick assembly and disassembly of the table legs and main body by rotating the actuator. During assembly, the table legs and main body are first connected via a connector, ensuring the locking groove on the connector is next to the locking element. Rotating the actuator then moves the linked locking element, inserting it into the locking groove for quick locking. Disassembly is simple: rotate the actuator in the opposite direction to disengage the locking element from the locking groove, then separate the table legs from the main body. Because this solution allows for quick assembly and disassembly, manufacturers can easily separate the two parts during packaging and transportation, significantly reducing costs and increasing efficiency. Consumers can also easily and quickly assemble the table legs and main body upon receiving the product, enhancing the user experience.

[0024] The linkage protrusion and linkage groove are linked to restrict the movement trajectory of the locking component through the trajectory of the linkage groove. The linkage groove always extends towards or away from the center of the actuating component between its two ends. Therefore, when it acts on the locking component, the locking component will always move in the radial direction of the actuating component, ensuring the smoothness of the locking component and ensuring different functions at different positions of the linkage groove. The linkage groove is V-shaped, so that the linkage groove and linkage protrusion are adapted to the rotation of the actuating component, and the two ends of the linkage groove provide different movement trajectories and functions. Although the linkage groove is V-shaped and has corners, its deflection arrangement on the rotation axis and the design of the fast movement section and the pressing section located on both sides of the rotation axis of the actuating component can take into account the direction of the linkage groove always moving away from or close to the rotation axis. The presence of the interference point can maintain the stability of the table legs and the main body when locked. Attached Figure Description

Detailed Implementation

[0042] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0044] In the description of this invention, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] The specific embodiments of the present invention are as follows:

[0046] like Figure 1-5 As shown, the present invention provides a table leg, including a leg body 1 and a table leg 2. The table leg 2 is detachably connected to the bottom of the leg body 1. One of the table leg 2 and the leg body 1 is provided with a connector 3, and the other is provided with a receiving space 4 and a slot 5 communicating with the receiving space 4 and allowing the connector 3 to be inserted into the receiving space 4. The receiving space 4 is provided with an actuating member 6, which is rotatably disposed in the receiving space 4. The actuating member 6 is linked to a locking member 7, which is movably disposed in the receiving space 4. The connector 3 is provided with a locking groove 31. When the connector 3 enters the receiving space 4 from the slot 5, the locking groove 31 is located next to the locking member 7. The rotation of the actuating member 6 drives the locking member 7 to move and enter the locking groove 31 to lock the table leg 2 and the leg body 1.

[0047] This solution allows for quick assembly and disassembly of the table leg 2 and the main body 1 by rotating the actuator 6. During assembly, the table leg 2 and the main body 1 are first connected to the slot 5 via the connector 3, with the locking groove 31 on the connector 3 positioned next to the locking element 7. Rotation of the actuator 6 then moves the locking element 7, inserting it into the locking groove 31, thus quickly locking the table leg 2 and the main body 1. For disassembly, simply rotate the actuator 6 in the opposite direction, causing the locking element 7 to move away from the locking groove 31, and then separate the table leg 2 from the main body 1. Because this solution enables quick assembly and disassembly of the table leg 2 and the main body 1, manufacturers can easily separate them during packaging and transportation, significantly reducing packaging and transportation costs and improving efficiency. Consumers can also easily and quickly assemble the table leg 2 and the main body 1 after receiving the product, enhancing the user experience.

[0048] Specifically, such as Figure 1-7As shown, this type of table leg is more commonly used in height-adjustable desks, meaning its structural layout is closer to that of a conventional height-adjustable desk leg. Two connectors 3 are located at the bottom of the leg body 1 and extend downwards. These two connectors 3 are symmetrically arranged, and a mounting plate 32 is positioned between them. Both ends of the mounting plate 32 are fixedly connected to the two connectors 3 respectively. The number of locking components 7 is the same as the number of connectors 3. A receiving space 4 and a slot 5 are provided on the table leg 2. The slot 5 is located on the upper surface of the table leg 2, and the receiving space 4 is located below the slot 5. The lower surface of the table leg 2 is open to accommodate the receiving space. The space 4 is open, allowing the user to operate the functional component 6 installed therein; there are two plug-in components 3 and two locking components 7, so that the connection between the table leg 2 and the leg body 1 is more stable. The plug-in component 3 is plate-shaped, and the two plug-in components 3 are installed to the bottom of the leg body 1 through the mounting plate 32, making the connection simpler. The plug-in component 3 with a simpler structure is set on the leg body 1, while the locking component 7 and the functional component 6 are set in the table leg 2, which also makes the table leg simpler in production and assembly. The leg body 1 does not need to open the accommodating space 4 and the slot 5, thus affecting its strength.

[0049] The locking element 7 is slidably or rotatably disposed in the accommodating space 4. The locking element 7 can selectively engage with the locking groove 31 by sliding or rotating in the accommodating space 4, and a more reasonable selection can be made according to the specific situation. In this embodiment, the locking element 7 is slidably disposed in the accommodating space 4. Furthermore, the accommodating space 4 is also provided with a mounting base 8. The table leg 2 is a hollow tube. The accommodating space 4 is located in the table leg 2. The mounting base 8 is fixed in the accommodating space 4, that is, the mounting base 8 is fixedly connected to the table leg 2. The actuating element 6 is disc-shaped or disc-shaped. The actuating element 6 is rotatably disposed on the mounting base 8. The locking element 7 is slidably disposed on the mounting base 8.

[0050] Specifically, such as Figure 5-8 As shown, the mounting base 8 has a sandwich structure with at least three layers from bottom to top. It includes a bottom limiting layer 81, a middle rotating layer 82, and an upper sliding layer 83. The rotating layer 82 is sandwiched between the limiting layer 81 and the sliding layer 83. The three are installed together with screws and fixed to the table leg 2. The rotating layer 82 has a circular cutout in the middle, which corresponds to the shape of the actuating member 6. The actuating member 6 is rotatably set in the rotating layer 82. The two parts of the limiting layer 81 press on the actuating member 6 to prevent it from falling off. The middle part of the limiting layer 81 is open to expose the linkage groove 62 and drive hole 61 on the actuating member 6. The sliding layer 83 has a groove in the middle to allow the locking member 7 to slide in it. Furthermore, there are two slots 5 arranged symmetrically. The two slots 5 are located on both sides of the mounting base 8 so that the connector 3 can be located on both sides of the mounting base 8 after being inserted into the slot 5. This means that the locking groove 31 on the connector 3 is located next to the locking member 7.

[0051] Furthermore, the end of the locking member 7 near the locking groove 31 has a bevel 71, and the thickness of the locking member 7 at the bevel 71 increases from the outside to the inside; the bevel 71 at the end of the locking member 7 makes it easier for the locking member 7 to enter the locking groove 31, and can also cooperate even when the locking member 7 and the locking groove 31 are not completely aligned.

[0052] The actuator 6 has a drive hole 61, which is a hexagonal hole. The actuator 6 does not have an operating part, which further reduces the packaging space and prevents the operating part on the table leg 2 from protruding and interfering with the table leg 2. Moreover, the drive hole 61 is a hexagonal hole, so the user can rotate the actuator 6 with an Allen wrench without the need for a special operating part.

[0053] Further describe the linkage relationship between locking element 7 and actuating element 6: such as Figure 7-14 As shown, the locking member 7 or the actuating member 6 is provided with a linkage protrusion 72, and the other is provided with a linkage groove 62. The linkage protrusion 72 is disposed in the linkage groove 62. When the actuating member 6 rotates, the linkage protrusion 72 moves in the linkage groove 62 to make the locking member 7 move toward or away from the locking groove 31. The linkage protrusion 72 is linked with the linkage groove 62 to limit the movement trajectory of the locking member 7 through the trajectory of the linkage groove 62. In this embodiment, the locking member 7 is provided with a linkage protrusion 72, and the actuating member 6 is provided with a linkage groove 62. There are two linkage grooves 62 to correspond to the two locking members 7.

[0054] Specifically, the linkage groove 62 is V-shaped and inclined relative to the rotation axis of the actuating member 6. The linkage groove 62 includes a connected rapid movement section 621 and a pressing section 622. The ends of the rapid movement section 621 and the pressing section 622 are located on both sides of the rotation axis of the actuating member 6, and the two are connected at the corner of the V-shaped linkage groove 62. This allows the linkage groove 62 and the linkage protrusion 72 to adapt to the rotation of the actuating member 6, and provides different motion trajectories and functions at the two ends of the linkage groove 62. When the linkage protrusion 72 moves toward the end of the rapid movement section 621, the locking member 7 moves away from the locking groove 31. When the linkage protrusion 72 moves toward the end of the pressing section 622, the locking member 7 moves closer to the locking groove 31; when the linkage protrusion 72 moves from the end of the rapid movement section 621 to the end of the pressing section 622, the distance between the linkage protrusion 72 and the rotation axis of the actuating member 6 increases; between the two ends of the linkage groove 62, it always extends toward or away from the center of the actuating member 6, so when it acts on the locking member 7, the locking member 7 will also always move in the radial direction of the actuating member 6, ensuring the smoothness of the locking member 7, and at the same time ensuring the different functions of the linkage groove 62 at different positions.

[0055] In the direction of approaching or moving away from the locking groove 31, the slope of the rapid movement segment 621 is greater than the slope of the pressing segment 622. Furthermore, in the radial direction of the actuating member 6, the distance traversed by the rapid movement segment 621 is greater than the distance traversed by the pressing segment 622. The greater slope of the rapid movement segment 621 allows the linkage protrusion 72 to quickly approach or move away from the rotation axis of the actuating member 6 when moving on the rapid movement segment 621, thereby causing the locking member 7 to quickly approach or move away from the locking groove 31. The linkage protrusion 72, moving in the linkage groove 62, will move away from or approach the rotation axis of the actuating member 6, thereby causing the locking member 7 to move closer to or away from the locking groove 31. When the linkage protrusion 72... During the rapid movement section 621, more radial displacement is generated, which in turn causes more sliding displacement of the locking member 7. When the locking member 7 is directly subjected to external force and moves inward, the linkage protrusion 72 and the linkage groove 62 abut against each other. The greater the slope, the easier it is for the linkage protrusion 72 and the linkage groove 62 to generate relative movement, which may cause the locking member 7 to disengage from the locking groove 31. Conversely, the smaller the slope, the less likely it is to generate relative movement. When it reaches the pressing section 622, the slope becomes gentler. Although the displacement generated is less, it can effectively prevent the linkage protrusion 72 and the linkage groove 62 from generating relative displacement, thus preventing the locking member 7 from disengaging from the locking groove 31 on its own.

[0056] Furthermore, an interference point is provided near the end of the clamping section 622. The interference point is configured such that when the linkage protrusion 72 passes through the interference point and is located at the end of the clamping section 622, the interference point stops the linkage protrusion 72 from moving towards the end of the rapid movement section 621. A stop rib 623 protruding towards the center of the groove is provided at the interference point. When the linkage protrusion 72 is located at the end of the clamping section 622, the stop rib 623 can effectively prevent the linkage protrusion 72 from leaving this location, thus maintaining the stability of the lock.

[0057] like Figure 15 , 16As shown, in some other embodiments, the actuating member 6 can be driven to rotate by the control member 9 and the rack 10. Specifically, the actuating member 6 is rotatably mounted on the mounting base 8, and the rack 10 is also slidably mounted in the mounting base 8. The outer contour of the actuating member 6 is provided with meshing teeth 11 that mesh with the rack 10. The meshing teeth 11 are arranged circumferentially on the outer contour of the actuating member 6. When the rack 10 slides in the mounting base 8 and the table leg 2, the actuating member 6 is driven to rotate through the meshing teeth 11, thereby driving the locking member 7 to move. The actuating member 6 can be driven to rotate by the sliding of the rack 10, thus eliminating the need for tools such as hex wrenches to disassemble and assemble the table legs. Furthermore, the table leg 2 is rotatably connected to the control member 9, which is a control wrench. The control component 9 is linked to the rack 10. When the control component 9 rotates near the table leg 2, it drives the rack 10 to slide and drives the locking component 7 into the locking groove 31. The control component 9 and the rack 10 are connected by a guide groove and guide block structure or a connecting rod structure to ensure that the rotation of the control component 9 will not affect the sliding of the rack 10, so that the transmission is smooth. In this embodiment, the control component 9 and the rack 10 are connected by a connecting rod 12, and the two ends of the connecting rod 12 are rotatably connected to the control component 9 and the rack 10 respectively. The user can directly control the rack 10 through the control component 9. In order to ensure a small packaging and transportation volume, the control component 9 can rotate to be close to the table leg 2. At the same time, when locking, the control component 9 is also close to the table leg 2 to prevent the control component 9 from protruding and tripping the consumer.

[0058] In other embodiments, the control member 9 has a cam portion, and the rack 10 is provided with a spring on the side away from the cam portion. The spring provides elastic force to the rack 10 so that the rack 10 always abuts against the cam portion. When the control member 9 rotates, the cam portion rotates accordingly to drive the rack 10 to slide on the mounting base 8.

[0059] In other embodiments, a receiving groove can be provided on the side end face of the table leg 2, so that the control member 9 can be rotatably disposed in the receiving groove. When the control member 9 rotates into the receiving groove, it drives the rack 10 to slide and drives the locking member 7 into the locking groove 31. The receiving groove for receiving the control member 9 is provided on the table leg 2, which can further reduce the packaging and transportation volume, so that the control member 9 can directly enter the receiving groove and will no longer protrude from the side of the table leg 2. Similarly, when locking is completed, the control member 9 can also be located in the receiving groove, so that the surface of the table leg 2 is flat.

1. A table leg, characterized in that: The table includes a detachably connected leg body and table legs. One of the table legs and one of the leg bodies has a connector with a locking groove. The other of the table legs and the leg body has a rotatable actuating member and a movable locking member. The actuating member and the locking member are linked. The table leg and the leg body are connected via the connector, and the rotation of the actuating member causes the locking member to enter the locking groove to lock the table leg and the leg body. The locking member has a linkage protrusion, and the actuating member has a linkage groove. The linkage protrusion is located in the linkage groove. When the actuating member rotates, the linkage protrusion and the linkage groove move relative to each other, causing the locking member to move towards or away from the locking groove. The linkage groove includes a connected rapid movement section and a pressing section. When the linkage protrusion moves toward the end of the rapid movement section, the locking member moves away from the locking groove; when the linkage protrusion moves toward the end of the pressing section, the locking member moves closer to the locking groove. When the linkage protrusion moves from the end of the rapid movement section to the end of the pressing section, the distance between the linkage protrusion and the rotation axis of the actuator increases. The linkage groove is V-shaped and inclined relative to the rotation axis of the actuator. The ends of the rapid movement section and the pressing section are located on both sides of the rotation axis of the actuator, respectively. There is an interference point near the end of the pressing section. The interference point is configured such that when the linkage protrusion passes through the interference point and is located at the end of the pressing section, the interference point stops the linkage protrusion from moving toward the end of the rapid movement section.

2. The table legs according to claim 1, characterized in that: In the direction of approaching or moving away from the locking groove, the slope of the rapid movement segment is greater than the slope of the clamping segment.

3. The table legs according to claim 2, characterized in that: In the radial direction of the action, the distance traversed by the rapid movement section is greater than the distance traversed by the clamping section.

4. The table legs according to claim 1, characterized in that: A stop bar protruding from the groove wall is provided at the interference point.

5. The table legs according to claim 1, characterized in that: The active component is disc-shaped or disc-shaped.

6. The table legs according to claim 1, characterized in that: The actuator has a driving hole, which is a hexagonal hole.

7. The table legs according to claim 1, characterized in that: The locking mechanism is slidable or rotatable within the table legs.

8. The table legs according to claim 1, characterized in that: The end of the locking element near the locking groove has a bevel, and the thickness of the locking element at the bevel increases from the outside to the inside.

9. The table legs according to claim 1, characterized in that: The connectors are located at the bottom of the leg body and extend downwards. There are two connectors in total, which are symmetrically arranged. A mounting plate is provided between the two connectors, and the two ends of the mounting plate are fixedly connected to the two connectors respectively. The number of locking pieces is the same as that of the connectors.

10. The table legs of the table according to any one of claims 1, characterized in that: A mounting base is fixed on the table leg, and the actuator is rotatably mounted on the mounting base. A rack is also slidably mounted in the mounting base. The outer contour of the actuator has meshing teeth that mesh with the rack. When the rack slides in the mounting base and the table leg, it drives the actuator to rotate, thereby driving the locking element to move.

11. The table legs according to any one of claims 10, characterized in that: A control component is rotatably connected to the table leg. The control component is linked to the rack. When the control component rotates near the table leg, it causes the rack to slide and drives the locking component into the locking groove.

12. The table legs according to claim 11, characterized in that: The table legs are provided with receiving grooves, and the control component is rotatably set in the receiving grooves. When the control component rotates into the receiving grooves, it drives the rack to slide and drives the locking component into the locking groove.

13. The table legs according to any one of claims 11, characterized in that: The control components are connected to the rack via a guide groove and guide block structure or a connecting rod structure.
