Description

Technical Field

[0001] The utility model belongs to the technical field of table legs and relates to a table leg and foot assembly and a table. Background Art

[0002] The mainstream table products on the market currently generally adopt a design strategy in which the table legs and table feet are detachable when considering transportation convenience. That is, the table feet need to be disassembled and separated from the table legs before transportation, and then packaged independently.

[0003] However, such table leg and foot assemblies mostly rely on screw fasteners for assembly and fixation, which means that consumers must invest time and effort to reassemble the table legs after receiving the goods. This process is not only inconvenient and reduces user satisfaction, but also increases the difficulty of product assembly and the potential risk of installation errors. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the prior art and to provide a table leg and foot assembly and a table.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a table leg and foot assembly, comprising:

[0006] A table leg, wherein the bottom surface of the table leg is provided with at least two upper locking holes;

[0007] A table foot, the table foot being rotatably connected to the table leg;

[0008] A locking unit, the locking unit comprising a limit block, the limit block is movably connected to the table leg, the limit block is provided with a limit pin, the limit block can move relative to the table leg so that the limit pin is inserted into the upper locking hole or withdrawn from the upper locking hole;

[0009] When the limiting pin is inserted into the upper locking hole, the table foot is restricted from rotating relative to the table leg; when the limiting pin is withdrawn from the upper locking hole, the table foot is allowed to rotate relative to the table leg.

[0010] Preferably, the table leg is provided with a lower locking hole, and the limit pin is movably inserted into the lower locking hole. When the upper locking hole is aligned with the lower locking hole, pushing the limit block toward the table leg can make the limit pin pass through the lower locking hole and be inserted into the upper locking hole to limit the rotation of the table leg relative to the table leg.

[0011] Preferably, the locking unit also includes an elastic member, one end of which abuts against the table foot and the other end of which abuts against the limit block, and under the action of the elastic member, the limit pin can withdraw from the upper locking hole to allow the table foot to rotate relative to the table leg.

[0012] Preferably, the locking unit further comprises an eccentric block, the eccentric block is rotatably connected to the table leg, and the eccentric block can be rotated to a locking position or an unlocking position;

[0013] When the eccentric block is in the locking position, the eccentric block contacts the limiting block and constrains the limiting pin in the upper locking hole; when the eccentric block is in the unlocking position, the limiting pin withdraws from the upper locking hole due to the elastic force of the elastic member.

[0014] Preferably, the limit block is further provided with a positioning pin, the table leg is provided with a positioning hole, the positioning pin is passed through the positioning hole, and the elastic member is sleeved on the positioning pin.

[0015] Preferably, it further comprises a handle, wherein the handle is connected to the eccentric block.

[0016] Preferably, the table leg is further provided with at least two first arc-shaped holes with the rotation center of the table leg as the center of the circle, and a connecting piece is provided in the first arc-shaped hole, and the connecting piece passes through the first arc-shaped hole to be fixedly connected to the table leg.

[0017] Preferably, it also includes a friction plate, which is arranged between the table foot and the bottom surface of the table leg, and the friction plate is provided with an avoidance hole and a second arc hole, the limit pin can pass through the avoidance hole and be inserted into the upper locking hole, the number of the second arc holes is the same as that of the first arc holes and is arranged one-to-one, and the connecting piece is also fixedly connected to the table leg through the second arc hole.

[0018] Preferably, the number of the upper locking holes is four, and the four upper locking holes are distributed in a ring shape with the rotation center of the table leg as the center of the circle.

[0019] A table comprises the table leg and table foot assembly, and also comprises a table top, wherein the table top is connected to the top of the table leg.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The table legs are locked and unlocked through a locking unit. The table legs do not need to be removed from the table legs during packaging and transportation. Instead, the lock between the table legs and the table legs can be released to rotate the table legs to a folded state, thereby achieving the purpose of folding and folding; when in use, the table legs can be rotated to the use state and the table legs and the table legs can be locked together, avoiding the complicated assembly operations that may be required by users.

[0022] 2. When the table leg and the table foot need to be locked as one, the limit block will achieve the locking action through the limit pin, and a part of the limit pin will penetrate into the pre-set lower locking hole of the table leg. At the same time, the other part of the limit pin will be accurately inserted into the upper locking hole at the bottom of the table leg; when the table leg needs to be unlocked in order to rotate or fold the table leg, the limit block is operated (for example, through the rotation of the eccentric block and the elastic force of the elastic part), which will prompt the limit pin to withdraw from the upper locking hole; despite this, in the process of releasing the upper lock, a part of the limit pin will still remain in the lower locking hole, which helps to maintain the relative position of the limit block and the table foot during the rotation of the table leg, ensuring the accuracy and convenience of subsequent re-locking.

[0023] 3. When the eccentric block is in the locked position, the protrusion on the eccentric block is in close contact with the limit block, which effectively constrains the limit block to the position closest to the table leg, ensuring that the limit pin is firmly inserted into the upper locking hole on the table leg, thereby limiting the rotation of the table leg relative to the table leg; when the table leg needs to be unlocked for angle adjustment, the eccentric block only needs to be rotated to the unlocked position. In this position, the protrusion of the eccentric block no longer constrains the limit block, and the elastic member will exert its force to push the limit block and make the limit pin withdraw from the upper locking hole, thereby releasing the restriction on the rotation of the table leg, and the user can easily rotate the table leg to the desired folding or use angle.

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] like Figure 1-7 As shown, a table leg and foot assembly includes: a table leg 100, wherein the bottom surface of the table leg 100 is provided with at least two upper locking holes 110; a table foot 200, wherein the table foot 200 is rotatably connected to the table leg 100; a locking unit, wherein the locking unit includes a limit block 300, wherein the limit block 300 is movably connected to the table foot 200, wherein the limit block 300 is provided with a limit pin 310, wherein the limit block 300 can be moved relative to the table foot 200 so that the limit pin 310 is inserted into the upper locking hole 110 or withdrawn from the upper locking hole 110; when the limit pin 310 is inserted into the upper locking hole 110, the table foot 200 is restricted from rotating relative to the table leg 100; and when the limit pin 310 is withdrawn from the upper locking hole 110, the table foot 200 is allowed to rotate relative to the table leg 100.

[0034] In the table leg and table foot assembly, the table leg 200 and the table leg 100 are connected in a rotational manner, that is, the table leg 200 can rotate relative to the table leg 100, and the limit block 300 in the locking unit is movably connected to the table leg 200, and when the limit pin 310 of the limit block 300 is aligned with the upper locking hole 110, it can be inserted into the upper locking hole 110 to lock the table leg 200 and the table leg 100 together, thereby limiting the relative rotation between the two, and when the limit pin 310 exits the upper locking hole 110, the table leg 200 can rotate relative to the table leg 100.

[0035] Among them, the table leg 200 can be rotated around the rotation center and locked in multiple preset positions to adapt to different space requirements and usage scenarios. Specifically, the bottom surface of the table leg 100 has at least two upper locking holes 110, which means that the table leg 200 has at least two locking states at different angles; when the table leg 200 is rotated to a set position, the limit pin 310 of the limit block 300 is aligned with one upper locking hole 110; and when the table leg 200 is rotated to another set position, the limit pin 310 of the limit block 300 is aligned with the other upper locking hole 110.

[0036] Based on the above structure, the limiting block 300 in the locking unit can be manipulated so that the limiting pin 310 can move along the designed path and then be inserted into or withdrawn from the upper locking hole 110 on the bottom surface of the table leg 100. When the limiting pin 310 is inserted into the upper locking hole 110, the table leg 200 cannot rotate relative to the table leg 100, that is, it reaches a locked state, and the table leg 200 is maintained at a fixed angle. If the angle of the table leg 200 is to be changed or folded up, the user can make the limiting pin 310 withdraw from the upper locking hole 110 through appropriate operation, and the table leg 200 can be freely rotated to the desired position, and the limiting pin 310 can be pushed again to insert into the corresponding upper locking hole 110 to re-lock the table leg 200.

[0037] During transportation and packaging, the limiting block 300 is first pulled to make the limiting pin 310 withdraw from an upper locking hole 110 to release the rotation restriction on the table leg 200. Then, the table leg 200 can be rotated along its rotation center to an angle suitable for reducing the packaging volume. In this way, the table leg 200 can be more tightly packaged with the table leg 100 without increasing too much packaging space. After receiving the goods, the user does not need to assemble them. First, make sure that the limiting block 300 is in an unlocked state, then rotate the table leg 200 to a suitable angle, and at this angle, the limiting pin 310 of the table leg 200 is aligned with a corresponding upper locking hole 110, and then push the limiting block 300 so that the limiting pin 310 is inserted into the corresponding upper locking hole 110, thereby locking the table leg 200 and the table leg 100 together to ensure that the table leg 200 is fixed in the use position.

[0038] The table leg 200 is locked and unlocked with the table leg 100 via a locking unit. During packaging and transportation, the table leg 200 does not need to be removed from the table leg 100. Instead, the lock between the table leg 200 and the table leg 100 can be released to rotate the table leg 200 to a folded state, thereby achieving the purpose of folding and folding. When in use, the table leg 200 can be rotated to a use state and the table leg 200 and the table leg 100 can be locked together, avoiding the complicated assembly operations that the user may need.

[0039] It should be supplemented that, in the example, the table leg 100 is composed of a leg tube and a connecting piece, the connecting piece is fixed to the bottom surface of the leg tube by screws, and the upper locking hole 110 is opened on the connecting piece.

[0040] like Figure 1-3As shown, on the basis of the above embodiment, the table leg 200 is provided with a lower locking hole 210. Specifically, the table leg 200 includes a flat plate, the upper surface of which is opposite to the table leg 100, and the lower surface of which is opposite to the limiting block 300, and the lower locking hole 210 passes through the upper and lower surfaces of the flat plate. The limiting pin 310 is movably provided in the lower locking hole 210, and when the upper locking hole 110 is aligned with the lower locking hole 210, the limiting block 300 is pushed upward so that the limiting pin 310 passes through the lower locking hole 210 and is inserted into the upper locking hole 110 to limit the rotation of the table leg 200 relative to the table leg 100.

[0041] The stop pin 310 locks the table leg 200 and the table leg 100 through the lower locking hole 210 and the upper locking hole 110, and the stop block 300 can move on the table leg 200 along the axis direction of the stop pin 310. When the table leg 100 and the table leg 200 need to be locked as one, the stop block 300 will achieve the locking action through the stop pin 310: a part of the stop pin 310 will be inserted into the lower locking hole 210 pre-set in the table leg 200, and at the same time, the other part of the stop pin 310 will be accurately inserted into the upper locking hole 110 at the bottom of the table leg 100. In this way, the upper locking hole 110 and the lower locking hole 210 cooperate with the stop pin 310 at the same time to form a stable locking structure, ensuring that the table leg 200 will not rotate at will, thereby firmly fixing the table leg 200 at a specified angle.

[0042] On the contrary, when the table leg 200 needs to be unlocked so as to rotate or fold the table leg 100, the limiting block 300 is operated (for example, by the rotation of the eccentric block 500 and the elastic force of the elastic member 400), which will cause the limiting pin 310 to withdraw from the upper locking hole 110. Nevertheless, during the process of releasing the upper lock, a part of the limiting pin 310 will still remain inside the lower locking hole 210, which helps to maintain the relative position of the limiting block 300 and the table leg 200 during the rotation of the table leg 200, ensuring the accuracy and convenience of the subsequent re-locking.

[0043] like Figure 1-7 As shown, on the basis of the above embodiment, the locking unit further includes an elastic member 400, one end of the elastic member 400 abuts against the table leg 200 and the other end abuts against the stop block 300, and under the action of the elastic member 400, the stop pin 310 can exit the upper locking hole 110 to allow the table leg 200 to rotate relative to the table leg 100. In the absence of other external forces, the elastic force of the elastic member 400 can push the stop block 300 downward, so that the stop pin 310 can exit the upper locking hole 110 to allow the table leg 200 to rotate relative to the table leg 100.

[0044] The role of the elastic member 400 is to maintain a continuous elastic force. Under normal conditions, the elastic member 400 always tends to push the stop block 300 to move away from the table leg 100, thereby driving the stop pin 310 to exit the upper locking hole 110. This means that when the external force constraint is removed, due to the force of the elastic member 400, the stop pin 310 will naturally try to leave the upper locking hole 110, so that the table leg 200 can be transformed from a locked state to a freely rotatable state. This design greatly simplifies the unlocking process of the table leg 200.

[0045] On the basis of the above embodiment, the locking unit also includes an eccentric block 500, which is rotatably connected to the table leg 200, and the eccentric block 500 can be rotated to a locked position or an unlocked position; when the eccentric block 500 is in the locked position, the eccentric block 500 contacts the limit block 300 and constrains the limit pin 310 in the upper locking hole 110; when the eccentric block 500 is in the unlocked position, the limit pin 310 withdraws from the upper locking hole 110 due to the elastic force of the elastic member 400.

[0046] The eccentric block 500 is rotatably connected to the table leg 200, that is, the eccentric block 500 can rotate around its own axis. According to different rotation positions, the eccentric block 500 can be switched to two states: locked or unlocked. The specific working principle is: the eccentric block 500 has a protrusion, and the eccentric block 500 controls the protrusion to contact or separate from the limit block 300 by rotating, thereby constraining the position of the limit block 300. Alternatively, it can be said that the distance between the circumferential outer wall of the eccentric block 500 and its rotation axis is unequal. When the circumferential outer wall far from the rotation axis contacts the limit block 300, the limit block 300 can be squeezed to move upward; when the circumferential outer wall close to the rotation axis is opposite to the limit block 300, a certain space is released between the circumferential outer wall of the eccentric block 500 and the limit block 300, and the limit block 300 can move downward under the action of the elastic member 400.

[0047] When the eccentric block 500 is in the locked position, the protrusion on the eccentric block 500 is in close contact with the limit block 300, thereby effectively constraining the limit block 300 at the position closest to the table leg 100, ensuring that the limit pin 310 is firmly inserted into the upper locking hole 110 on the table leg 100, thereby limiting the rotation of the table leg 200 relative to the table leg 100.

[0048] When it is necessary to unlock the table leg 200 for angle adjustment, the eccentric block 500 only needs to be rotated to the unlocking position. In this position, the protrusion of the eccentric block 500 no longer constrains the limit block 300, and the elastic member 400 will exert its force to push the limit block 300 and make the limit pin 310 withdraw from the upper locking hole 110, thereby releasing the restriction on the rotation of the table leg 200, and the user can easily rotate the table leg 200 to the desired folding or use angle.

[0049] like Figure 1-5 , Figure 7 As shown, on the basis of the above embodiment, the limit block 300 is further provided with a positioning pin 320 , the table leg 200 is provided with a positioning hole 220 , the positioning pin 320 is passed through the positioning hole 220 , and the elastic member 400 is sleeved on the positioning pin 320 .

[0050] The limit block 300 is also specially provided with a positioning pin 320, and correspondingly, a matching positioning hole 220 is provided on the table leg 200. The positioning pin 320 is designed to ensure that the limit block 300 can accurately correspond to the table leg 200 during the movement and maintain the precise positional relationship between the two. The specific working principle is: the positioning pin 320 passes through the positioning hole 220 on the table leg 200 to guide and limit the movement trajectory of the limit block 300, ensuring that the limit block 300 can be aligned or disengaged with the upper locking hole 110 in a timely manner as the table leg 200 rotates. In addition, in order to provide sufficient stability and reset capability, the elastic member 400 (which may be a spring or other type of elastic member) is carefully designed and sleeved on the positioning pin 320. In actual application, the elastic member 400 will provide a certain rebound force when the limit block 300 moves. When the table leg 200 is switched from a locked state to an unlocked state, the elastic member 400 can assist the limit block 300 to return to a predetermined position and assist the limit pin 310 to exit the upper locking hole 110 according to the design intention, thereby ensuring the reliability and flexibility of the entire locking unit.

[0051] like Figure 1-6 As shown, on the basis of the above embodiment, a handle 600 is further included, and the handle 600 is connected to the eccentric block 500. The handle 600 is effectively mechanically connected to the eccentric block 500. By manually shaking the handle 600, the user can directly control the rotation of the eccentric block 500. When the user needs to adjust the angle of the table leg 200 or fold it, he only needs to grab the handle 600 and apply appropriate force to rotate it. This rotation action will be synchronously transmitted to the eccentric block 500, so that the eccentric block 500 turns from the locked position to the unlocked position, or vice versa.

[0052] like Figure 1-5 As shown, based on the above embodiment, the table leg 200 is further provided with at least two first arc holes 230 with the rotation center of the table leg 200 as the center, and a connecting member 240 is provided in the first arc hole 230, and the connecting member 240 passes through the first arc hole 230 and is fixedly connected to the table leg 100.

[0053] This design abandons the traditional method of directly connecting the table leg 100 and the table foot 200 through a rotating shaft to achieve rotation, and instead uses the sliding of the connecting member 240 in the first arc-shaped hole 230 to achieve the same rotation effect.

[0054] On the basis of the above embodiment, it also includes a friction plate 700, which is arranged between the bottom surface of the table foot 200 and the table leg 100. The friction plate 700 is provided with an avoidance hole 710 and a second arc hole 720. The limit pin 310 can pass through the avoidance hole 710 and be inserted into the upper locking hole 110. The number of the second arc holes 720 is the same as that of the first arc holes 230 and is arranged one by one. The connecting piece 240 also passes through the second arc hole 720 to be fixedly connected with the table leg 100.

[0055] The friction plate 700 is located between the table foot 200 and the table leg 100, which serves to raise the table foot 200 and prevent the table leg 100 from directly contacting the table foot 200 and causing wear during rotation (the friction plate 700 serves as the contact interface between the table frame and the table leg 100, and has good wear resistance, which can effectively prevent direct wear during the relative rotation of the table leg 100 and the table foot 200, ensuring that both will not be damaged due to long-term use).

[0056] The avoidance hole 710 is a channel specially reserved for the limit pin 310 on the friction plate 700. When the limit pin 310 needs to pass through the friction plate 700 from the table foot 200 to the upper locking hole 110 of the table leg 100 for locking, the avoidance hole 710 provides enough space for the limit pin 310 to pass through without obstacles, ensuring the smooth locking process. The second arc hole 720 is also designed to avoid the connection member 240. The connection member 240 needs to extend to the table leg 100 through the first arc hole 230 on the table foot 200 for fixed connection, and the second arc hole 720 on the friction plate 700 just corresponds to it, so that the connection member 240 can slide freely in the two arc holes during the rotation of the table foot 200, thereby realizing the flexible rotation and firm connection of the table foot 200 and the table leg 100. The relevant components can operate correctly and stably without interference.

[0057] like Figure 1-2 As shown, based on the above embodiment, the number of upper locking holes 110 is four, and the four upper locking holes 110 are distributed in a ring shape with the rotation center of the table leg 200 as the center. This layout means that the table leg 200 can be rotated to four different preset angles, and at each angle position, the table leg 200 can be locked at that angle by inserting the limit pin 310 into the corresponding upper locking hole 110, thereby realizing multiple adjustment and fixing functions of the angle of the table leg 200.

[0058] In the example, the table leg 200 is provided with four lower locking holes 210 with the rotation center of the table leg 200 as the center of the circle. The four lower locking holes 210 correspond to the four upper locking holes 110 one by one. When the table leg 200 is rotated to a specific angle, the four limit pins 310 on the limit block 300 can be accurately aligned and inserted into the upper locking holes 110 of the table leg 100 and the lower locking holes 210 of the table leg 200 respectively. In this way, the table leg 200 can be firmly locked at four preset angle positions, ensuring that the relative position between the table leg 200 and the table leg 100 is fixed and unchanged, thereby ensuring the overall stability of the table.

[0059] like Figure 1-7 As shown, a table includes a table leg and table foot assembly, and also includes a table top, which is connected to the top of the table leg 100. The main structure of this table includes two parts: the table leg and table foot assembly and the table top. The number of the table leg and table foot assemblies is at least two, and the table leg and table foot assemblies can support the table top to ensure the stability of the table top. Preferably, the table top is rotatably connected to the table leg 100. In this way, the table top, the table leg and the table foot can be folded into a plate-like shape, further saving the packaging size.

[0060] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0061] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0062] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
