Description

Technical Field

[0001] This application relates to the field of furniture and equipment technology, specifically to a connection structure between table legs and table feet, and a table. Background Technology

[0002] To accommodate users of different heights, most tables are height-adjustable. Taking an electric height-adjustable table as an example, its structure includes a tabletop, legs, a crossbeam, and two height-adjustable legs. The tabletop is connected to the top of the crossbeam, the upper ends of the legs are connected to the crossbeam, and the lower ends of the legs are connected to the table legs. To reduce packaging volume and save on packaging costs, manufacturers often package the crossbeam, legs, and table legs separately, requiring users to assemble the components themselves after purchase. In tables using the aforementioned technology, the table legs are typically bolted to the lower end of the table legs. This installation method requires drilling holes in the table legs, aligning the holes in the table legs with pre-drilled screw holes on the lower end of the table legs, and then inserting bolts from bottom to top to secure them, thus assembling the table legs and table legs.

[0003] The table legs of the aforementioned related technologies have some shortcomings in the actual assembly process: tools must be used to tighten and loosen bolts during the assembly and disassembly of the table legs, which is quite time-consuming and laborious, and cannot meet the user's need for quick assembly. Utility Model Content

[0004] The technical problem to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a connection structure between table legs and table legs that does not require the use of tools to tighten or loosen bolts, is simple, convenient and labor-saving to assemble, and can meet the user's need for rapid assembly.

[0005] The technical solution of this application is to provide a connection structure between a table leg and a table leg, which includes a locking rod disposed on one of the table leg and the other table leg, and a lock hole on the other table leg that is adapted to be inserted into the locking rod. The locking rod is inserted into the lock hole and can move between an unlocked position and a locked position in the lock hole. A cam is rotatably connected to one of the table leg and the other table leg, and a positioning hole is provided on the other table leg that is inserted into the cam. The cam rotates and switches between a first position and a second position. When the cam rotates to the first position, the convex part of the cam presses against the inner wall of the positioning hole to move the locking rod to the locked position of the lock hole, and the table leg and the table leg are locked and fixed. When the cam rotates to the second position, the convex part of the cam disengages from the inner wall of the positioning hole, and the locking rod can move from the locked position to the unlocked position of the lock hole.

[0006] In some embodiments, the bottom of the table leg is connected to a base plate, and a plurality of vertically arranged locking rods are connected to the base plate. The cam is rotatably connected to the base plate. There are a plurality of locking holes, which are respectively arranged on the table leg, and the positioning hole is arranged on the table leg. When the locking rod is inserted into the locking hole, the cam is accommodated in the positioning hole.

[0007] In some embodiments, the locking rod includes a rod body and a limiting post disposed on the free end of the rod body, wherein the outer diameter of the limiting post is larger than the outer diameter of the rod body, and the limiting post is located outside the lock hole when the locking rod is inserted into the lock hole.

[0008] In some embodiments, the lock hole includes a first hole and a second hole communicating with the first hole, wherein the diameter of the second hole is smaller than the diameter of the first hole; the diameter of the first hole is greater than or equal to the outer diameter of the limiting post, and the diameter of the second hole is greater than or equal to the outer diameter of the rod and smaller than the outer diameter of the limiting post.

[0009] In some embodiments, the rod of the locking bar is threadedly connected to the base plate.

[0010] In some embodiments, the cam is provided with a connecting hole for inserting a wrench to drive the cam to rotate, or the cam is connected with a drive wrench for driving the cam to rotate.

[0011] In some embodiments, the table leg includes a foot plate and a bottom shell fixedly connected to the bottom of the foot plate. The locking hole and the positioning hole are both provided on the foot plate, and the bottom of the bottom shell has a notch for exposing the locking hole and the positioning hole.

[0012] In summary, the connection structure between the table leg and table leg of this application has the following advantages compared with related technologies: the connection structure between the table leg and table leg has a locking rod on one of the table leg and table leg, and a locking hole adapted to the locking rod for insertion on the other, and the locking hole has an unlocking position and a locking position; furthermore, a cam is rotatably connected to one of the table leg and table leg, and a positioning hole is provided on the other for insertion and cooperation with the cam. When the cam rotates to the first position, the cam's protrusion presses against the inner wall of the positioning hole to move the locking rod to the locking position of the locking hole, at which time the table leg and table leg are locked and fixed; and when the cam rotates to the second position, the cam's protrusion disengages from the inner wall of the positioning hole, and the locking rod can move from the locking position of the locking hole to the unlocking position. In other words, when connecting the table legs to the table feet, the locking rods and lock holes of both are engaged. At this time, the cam is located in the positioning hole. Rotating the cam causes the eccentric protrusion of the cam to press against the inner wall of the positioning hole, causing the table legs and table feet to move relative to each other. This moves the locking rod to the locking position of the lock hole and locks it in place, thus completing the installation of the table legs and table feet. The entire installation process does not require the use of tools to tighten or loosen bolts. Assembly is simple, convenient, labor-saving, and meets the user's need for quick assembly. Conversely, when disassembling the table legs, simply rotate the cam again to disengage the cam protrusion from pressing against the inner wall of the positioning hole. At this time, there is a play between the inner wall of the positioning hole and the cam, allowing the locking rod to move from the locked position of the lock hole to the unlocked position, thus removing the table legs. The operation is simple and convenient.

[0013] Another technical solution of this application is to provide a table with the following structure: a tabletop, table legs, and table feet, wherein the connection structure between the table feet and the table legs adopts the table foot and table leg connection structure described in any of the above embodiments. This table uses the table foot and table leg connection structure of the above embodiments. When connecting the table feet and table legs, it is only necessary to mate the locking rods and locking holes of both, and then rotate the cam. This causes the eccentric protrusion of the cam to press against the inner wall of the positioning hole, causing the table feet and table legs to move relative to each other. The locking rod moves to the locking position of the locking hole and locks, thereby completing the installation of the table feet and table legs. The entire installation process does not require the use of tools to tighten or loosen bolts, making assembly simple, convenient, labor-saving, and increasing the table assembly speed.

[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1 to 7 As shown in the figure, this application discloses a connection structure between a table leg and a table leg, used for the installation between a table leg 1 and a table leg 2. The connection structure includes a locking rod 3 disposed on one of the table leg 2 and the table leg 1, and a locking hole 4 on the other table leg that is adapted to be inserted into the locking rod 3. The locking rod 3 is inserted into the locking hole 4 and can move between the unlocked position and the locked position in the locking hole 4. That is, when the table leg 2 and the table leg 1 are installed, the locking rod 3 on one of them is inserted into the locking hole 4 on the other, so that the table leg 2 and the table leg 1 move relative to each other, thereby moving the locking rod 3 in the locking hole 4 to the locked position of the locking hole 4, or from the locked position of the locking hole 4 to the unlocked position.

[0029] In this embodiment, see Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a base plate 100 is connected to the bottom of the table leg 1, and a locking rod 3 is connected to the base plate 100. A locking hole 4 is provided on the table leg 2 to engage with the locking rod 3. The diameter of the locking hole 4 is larger than the outer diameter of the locking rod 3, allowing the locking rod 3 to be inserted into the locking hole 4 and to move within it. It can be understood that the position in the locking hole 4 where the locking rod 3 is inserted is also the unlocking position, and the position in the locking hole 4 that restricts the movement of the locking rod 3 is also the locking position. In other words, the position where the locking rod 3 moves within the locking hole 4 until it abuts against the inner wall of the locking hole 4 is also the locking position.

[0030] It is easy to understand that when the locking rod 3 moves to the locking position within the lock hole 4, the table leg 2 is secured to the bottom of the table leg 1. The locking engagement between the locking rod 3 and the lock hole 4 can be implemented in various ways. For example, a locking hook extending radially outward from the free end of the locking rod 3 can be provided. When the locking rod 3 moves to the locking position within the lock hole 4, the locking hook engages with the lock hole 4, thus securing or locking the table leg 2 to the bottom of the table leg 1. Alternatively, a pin extending radially outward from the free end of the locking rod 3 can be provided. The inner wall of the lock hole 4 has an insertion hole. When the locking rod 3 moves to the locking position of the lock hole 4, the pin on the locking rod 3 is inserted and fixed into the insertion hole on the inner wall of the lock hole 4, thereby securing or locking the table leg 2 to the bottom of the table leg 1. Alternatively, a slot or wedge-shaped slot with a width slightly smaller than the outer diameter of the locking rod 3 can be provided at the locking position of the lock hole 4. When the locking rod 3 moves to the locking position of the lock hole 4, the locking rod 3 is tightly fitted into the slot of the lock hole 4, thereby securing or locking the table leg 2 to the bottom of the table leg 1. In this embodiment, see... Figure 3 , Figure 4 and Figure 5 As shown, the locking rod 3 includes a rod body 300 connected to the base plate 100 and vertically downward, and a limiting pin 301 disposed on the lower end or free end of the rod body 300. The outer diameter of the limiting pin 301 is larger than the outer diameter of the rod body 300. When the locking rod 3 is inserted into the lock hole 4, the limiting pin 301 is located outside the lock hole 4. When the locking rod 3 is inserted into the lock hole 4 and moves until the rod body 300 abuts against the inner wall of the lock hole 4, a portion of the limiting pin 301 engages with the end face outside the lock hole 4, thereby limiting the table leg 2 relative to the table leg 1 in both the horizontal and vertical directions, thus securing the table leg 2 to the bottom of the table leg 1.

[0031] Furthermore, in this embodiment, the rod body 300 of the locking rod 3 is threadedly connected to the base plate 100, thereby adjusting the length of the locking rod 3 extending out of the base plate 100, or adjusting the distance between the limiting column head 301 and the base plate 100, so as to adapt to table legs 2 with different wall thicknesses and improve their versatility.

[0032] In other embodiments, the locking rod 3 can also be connected to the table leg 2, and the locking hole 4 can be set on the table leg 1. Specifically, a vertically arranged locking rod 3 is fixedly connected to the top of the table leg 2, and a locking hole 4 for the locking rod 3 to be inserted is provided on the bottom plate 100 of the bottom of the table leg 1. When the table leg 2 is installed with the table leg 1, the locking rod 3 on the table leg 2 is inserted into the locking hole 4 of the bottom plate 100 of the table leg 1 from bottom to top. Then the table leg 2 is moved so that the locking rod 3 moves to the locking position of the locking hole 4, thereby fixing the table leg 2 to the bottom of the table leg 1.

[0033] Furthermore, in this embodiment, to make the connection between the table leg 2 and the table leg 1 more secure and stable, multiple locking rods 3 and locking holes 4 are provided, see [reference]. Figure 3 and Figure 5 As shown, multiple locking rods 3 are connected to the base plate 100 at the bottom of the table leg 1, and multiple locking holes 4 are set on the table leg 2. The locking holes 4 and the locking rods 3 are inserted one by one. When the table leg 2 moves relative to the table leg 1, all the locking rods 3 can move to the locking position of the locking holes 4 at the same time, thus making the connection between the table leg 2 and the table leg 1 more firm and stable.

[0034] Furthermore, the connection structure between the table leg and the table leg also includes a cam 6 rotatably connected to one of the table leg 2 and the table leg 1, and a positioning hole 5 provided on the other for insertion and engagement with the cam 6; specifically in this embodiment, see further details. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, cam 6 is rotatably connected to the bottom of table leg 1, and positioning hole 5 that mates with cam 6 is provided on table leg 2. Cam 6 rotates between a first position and a second position. When cam 6 rotates to the first position, the protrusion 600 of cam 6 presses against the inner wall of positioning hole 5 to move locking rod 3 to the locking position of locking hole 4, and table leg 2 is locked and fixed to table leg 1. When cam 6 rotates to the second position, the protrusion 600 of cam 6 disengages from the inner wall of positioning hole 5, and locking rod 3 can move from the locking position of locking hole 4 to the unlocking position.

[0035] In this embodiment, when connecting table leg 2 and table leg 1, the locking rod 3 and locking hole 4 of both are engaged. At this time, cam 6 is located in positioning hole 5. Rotating cam 6 causes the eccentric protrusion 600 of cam 6 to press against the inner wall of positioning hole 5, causing table leg 2 and table leg 1 to move relative to each other. This moves locking rod 3 to the locking position of locking hole 4 and locks it in place, thus completing the installation of table leg 2 and table leg 1. The entire installation process does not require the use of tools to tighten or loosen bolts. Assembly is simple, convenient, labor-saving, and meets the user's need for rapid assembly. Conversely, when disassembling table leg 2, simply rotate cam 6 again to disengage the protrusion 600 of cam 6 from pressing against the inner wall of positioning hole 5. At this time, there is a movable gap between the inner wall of positioning hole 5 and cam 6, allowing locking rod 3 to move from the locking position of locking hole 4 to the unlocking position, thereby disassembling table leg 2. The operation is simple and convenient.

[0036] It is understood that the cam 6 is rotatably connected to the base plate 100 at the bottom of the table leg 1 via a rotating shaft. The outer peripheral wall of the cam 6 has a distal end and a proximal end relative to the rotating shaft. The distal end is the protrusion 600 of the cam 6, and the proximal end is in the opposite position to the distal end and is located closer to the rotating shaft. The cam 6 fits in the positioning hole 5. When the cam 6 rotates, the protrusion 600 of the cam 6 pushes or squeezes the squeezing part of the inner wall of the positioning hole 5, causing the table leg 2 to move relative to the table leg 1, thereby allowing the locking rod 3 to move to the locking position of the locking hole 4. Rotating the cam 6 again causes the protrusion 600 of the cam 6 to disengage from the squeezing part of the inner wall of the positioning hole 5, or causes the cam 6 to rotate so that the proximal end of the cam 6 faces the squeezing part of the inner wall of the positioning hole 5. At this time, there is a gap between the squeezing part of the inner wall of the positioning hole 5 and the cam 6. At this time, the table leg 2 can be moved so that the locking rod 3 moves from the locking position of the locking hole 4 to the unlocking position, thereby removing the locking rod 3 from the locking hole 4.

[0037] For example, see Figure 6 As shown, when connecting table leg 2 to table leg 1, the locking holes 4 on table leg 2 and locking rods 3 on table leg 1 are aligned and engaged. At this time, cam 6 is inserted into the positioning hole 5 on table leg 2, and the protrusion 600 of cam 6 is away from the pressing part of the inner wall of positioning hole 5. When cam 6 is rotated, the protrusion 600 of cam 6 presses against the inner wall of positioning hole 5, causing table leg 2 to translate relative to table leg 1. This causes locking rod 3 to move relative to table leg 2 towards the side of locking hole 4 and move locking rod 3 to the locking position of locking hole 4. See [link to documentation]. Figure 7 As shown, under the pressure of the protrusion 600 of the cam 6 and the inner wall of the positioning hole 5, the locking rod 3 and the locking hole 4 are engaged and locked, and the table leg 2 is firmly connected to the table leg 1.

[0038] In other embodiments, the cam 6 can be rotatably connected to the table leg 2, and the positioning hole 5 can be set on the bottom plate 100 at the bottom of the table leg 1. In this case, rotating the cam 6 will cause the cam 6 to press against the inner wall of the positioning hole 5, so that the table leg 2 moves synchronously with the cam 6, and the locking rod 3 reaches the locking position of the locking hole 4.

[0039] Therefore, the connection structure between the table legs and table feet in this application embodiment includes the following four implementation methods: The first one, which is this embodiment... Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in the first method, the locking rod 3 and the cam 6 are set on the bottom plate 100 at the bottom of the table leg 1, and the locking hole 4 and the positioning hole 5 are set on the table leg 2 respectively; in the second method, the opposite of the first method, the locking rod 3 and the cam 6 are set on the table leg 2, and the locking hole 4 and the positioning hole 5 are set on the bottom plate 100 at the bottom of the table leg 1 respectively; in the third method, the locking rod 3 and the positioning hole 5 are set on the bottom plate 100 at the bottom of the table leg 1, and the locking hole 4 and the cam 6 are set on the table leg 2 respectively; in the fourth method, the locking hole 4 and the cam 6 are set on the bottom plate 100 at the bottom of the table leg 1, and the locking rod 3 and the positioning hole 5 are set on the table leg 2 respectively.

[0040] Further in this embodiment, see Figure 5 and Figure 6 As shown, the lock hole 4 includes a first hole 400 and a second hole 401 connected to the first hole 400. The diameter of the second hole 401 is smaller than that of the first hole 400. The diameter of the first hole 400 is greater than or equal to the outer diameter of the limiting pin 301, and the diameter of the second hole 401 is greater than or equal to the outer diameter of the rod 300 and smaller than the outer diameter of the limiting pin 301. In this embodiment, the lock hole 4 is a gourd-shaped hole. The first hole 400 is used for the insertion of the lock rod 3, which is also the unlocking position of the lock hole 4. The second hole 401 is used for locking the lock rod 3, which is also the locking position of the lock hole 4. When the lock rod 3 moves to the second hole 401 of the lock hole 4, the rod body 300 of the lock rod 3 abuts against the inner wall of the second hole 401 and is limited. Under the action of the second hole 401, the rod body 300 of the lock rod 3 is limited in all horizontal directions except the direction towards the first hole 400. Moreover, the engagement of the limiting post 301 with the end face of the lock hole 4 makes the lock rod 3 firmly locked in the lock hole 4, making the connection between the table leg 2 and the table leg 1 more stable and firm.

[0041] In this embodiment, to facilitate the rotation of cam 6, a connecting hole 601 is provided on cam 6 for inserting a wrench to drive the rotation of cam 6. See [link to documentation]. Figure 5 As shown, the connecting hole 601 is a polygonal hole, which can be inserted into an L-shaped polygonal wrench, thereby making it easier to rotate the cam 6 and making the installation of the table leg 2 more convenient and labor-saving.

[0042] In some embodiments, see Figure 8 As shown, in order to facilitate the rotation of cam 6, a drive wrench 602 for driving cam 6 to rotate is connected to cam 6. That is, cam 6 comes with a wrench, which makes it easier to rotate cam 6 and makes the installation of table leg 2 more convenient.

[0043] In this embodiment, see Figure 4 and Figure 5As shown, the table leg 2 includes a foot plate 200 and a bottom shell 201 fixedly connected to the bottom of the foot plate 200. The locking hole 4 and the positioning hole 5 are both provided on the foot plate 200, and the bottom of the bottom shell 201 has a notch 202 for the locking hole 4 and the positioning hole 5 to be exposed. This design makes it convenient for users to assemble the table leg 2.

[0044] Another embodiment of this application discloses a table, including a tabletop, table legs 1, and table feet 2. The connection structure between table feet 2 and table legs 1 adopts the connection structure of table feet and table legs in any of the above embodiments. When connecting table feet 2 and table legs 1, it is only necessary to mate the locking rods 3 and locking holes 4, and then rotate the cam 6. This causes the eccentric protrusion 600 of the cam 6 to press against the inner wall of the positioning hole 5, causing the table feet 2 and table legs 1 to move relative to each other. The locking rods 3 move to the locking position of the locking hole 4 and lock, thereby completing the installation of table feet 2 and table legs 1. The entire installation process does not require the use of tools to tighten or loosen bolts. The assembly is simple, convenient, labor-saving, and can improve the assembly speed of the table.
