Description

Technical Field

[0001] The present invention relates to a table frame, in particular to a table frame with quick-installable table feet. Background Art

[0002] Since installing table feet can make the placement of the table frame on the ground more stable, installing table feet under the table legs is very common in production and use. However, currently, the installation of table feet on the market is generally carried out by screws or bolts. Screws or bolts are not only easily omitted during the packaging by merchants but also easily lost during the installation by users. Moreover, when users install, they need to align the pre-drilled holes on the table legs and table feet, place the screws or bolts, and use tools to tighten them laboriously, which is very time-consuming and laborious. Summary of the Invention

[0003] The purpose of the present invention is to provide a table frame with quick-installable table feet, including: table legs and table feet installed at the lower ends of the table legs. The table feet further include two opposite side surfaces, and each side surface is provided with two sliding grooves, namely a first sliding groove and a second sliding groove. At least two rotatable arms hinged to each other are further provided inside the table feet. One end of each rotatable arm is hinged to each other through a hinge shaft, and the other end of each rotatable arm is connected to a locking rod respectively, namely a first locking rod and a second locking rod. The two ends of the first locking rod are slidably connected to the first sliding grooves on the two side surfaces, and the two ends of the second locking rod are slidably connected to the second sliding grooves on the two side surfaces. The first locking rod and the second locking rod move between an unlocking position and a locking position in the sliding grooves; the first locking rod and the second locking rod are further connected by an elastic connecting member for providing a pulling force to make the two approach each other when the first locking rod and the second locking rod move away from each other in the sliding grooves; at least two locking hooks are provided at the lower end of the table legs. When the locking rods are located at the unlocking positions in the sliding grooves, the first locking rod and the second locking rod approach each other, the hinge shaft is located below the plane where the center lines of the first locking rod and the second locking rod are located, the locking rods are disengaged from the locking hooks, the table legs can move up and down relative to the table feet, and the locking hooks can move into the table feet. When the first locking rod and the second locking rod move towards the direction of moving away from each other to the locking positions, the hinge shaft moves above the plane where the center lines of the first locking rod and the second locking rod are located. Due to the elastic connecting member applying a pulling force to the two locking rods, the two locking rods apply a squeezing force to the ends of the locking hooks located inside the table feet, so that the locking rods and the locking hooks are mutually locked to prevent the table legs from detaching from the table feet.

[0004] The beneficial effect is that the user only needs to press the hinge shaft. When the hinge shaft moves below the plane formed by the center lines of the two locking rods, the elastic connecting member provides a pulling force for the two locking rods to approach each other as the two locking rods move away from each other. Therefore, at the locking position, the locking rods apply a squeezing force to the end of the locking hook and finally lock. The whole process is simple for the user to operate. The connection between the table leg and the table foot is locked by the locking rod and the locking hook, and the connection becomes more stable due to the abutment of the table foot and the table leg against each other with this locking.

[0005] Preferably, a positioning groove adapted to the locking hook is provided at the upper end of the table foot. During installation, the locking hook is inserted into the positioning groove, and the positioning groove plays a role in positioning before the connection between the table leg and the table foot.

[0006] Preferably, a foot pad is provided at the lower end of the table foot.

[0007] Preferably, the locking rod passes through the sliding groove, and anti-disengagement members are provided at both ends of the locking rod extending outside the sliding groove.

[0008] Preferably, the first locking rod and the second locking rod are parallel locking rods.

[0009] Preferably, the table foot is a hollow structure, the hinge shaft is connected to a pressing member, and a pressing port for the pressing member to extend out is provided at the lower end of the table foot.

Detailed implementation mode

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above - mentioned terms should not be construed as limiting the present invention.

[0021] As Figures 1 to 7 shown, in a preferred embodiment of the present invention, a table frame with a quick - installation table leg includes: table leg 2, and table foot 1 installed at the lower end of table leg 2. It should be noted that the upper and lower positions in the following description are based on the position of the table foot below the table leg; the table foot 1 further includes two opposite sides 111, 112, and each side is provided with two sliding grooves, namely first sliding groove 161 and second sliding groove 162. At least two mutually hinged rotating arms 13 are further provided inside the table foot 1. One end of the rotating arm 13 is hinged to each other through a hinge shaft 18, and the other end of each is connected to a locking rod, namely first locking rod 121 and second locking rod 122. The shapes of the first locking rod 121 and the second locking rod 122 are not limited to straight rod shapes. The locking rods in this embodiment are as Figures 2 to 6Shown are straight rods arranged parallel to each other. Both ends of the first locking rod 121 are slidably connected to the first sliding grooves 161 on two sides 111 and 112. Both ends of the second locking rod 122 are slidably connected to the second sliding grooves 162 on two sides 111 and 112. The first locking rod 121 and the second locking rod 122 move between the unlocking position and the locking position in the sliding grooves. The first locking rod 121 and the second locking rod 122 are also connected by an elastic connecting member 15, which is used to provide a pulling force to make the two approach each other when the first locking rod 121 and the second locking rod 122 move away from each other in the sliding grooves. Figures 2 to 6 Among them, the number of the elastic connecting members 15 is two, which are symmetrically installed on both sides near the two ends of the locking rod. The elastic connecting member 15 can be a spring. At least two locking hooks 21 are provided at the lower end of the table leg 2. As Figures 2 to 6 shown in Figures 2 to 6 , the number of the locking hooks 21 is four, and they are arranged in pairs symmetrically at the four corners of the lower end of the table leg. When the first locking rod 121 and the second locking rod 122 are in the unlocking position in the first sliding groove 161 and the second sliding groove 162, the first locking rod 121 and the second locking rod 122 approach each other. The hinge shaft 18 is located below the plane where the center lines of the first locking rod 121 and the second locking rod 122 are located. The locking rod is disengaged from the locking hook 21, and the table leg 2 can move up and down relative to the table foot 1. The locking hook 21 can move into the table foot 1. When the first locking rod 121 and the second locking rod 122 move away from each other to the locking position, the hinge shaft 18 moves above the plane where the center lines of the first locking rod 121 and the second locking rod 122 are located. Due to the elastic connecting member 15 applying a pulling force to the two locking rods, the two locking rods apply a squeezing force to the end of the locking hook 21 located in the table foot 1, so that the locking rod and the locking hook 21 are locked with each other, preventing the table leg 2 from detaching from the table foot 1. It should be noted that when the locking rod applies a squeezing force to the end of the locking hook 21, the lower end of the table leg 2 also applies a squeezing force to the upper end of the table foot 1, ensuring the stability of the installation.

[0022] Further, referring to Figures 2 to 7 , a positioning groove 11 adapted to the locking hook 21 is provided at the upper end of the table foot 1. When installing the table foot 1, align the locking hook 21 with the positioning groove 11 and insert it. This facilitates the positioning of the locking hook 21 in the table foot 1 and its locking with the locking rod.

[0023] Further, a foot pad 3 is provided at the lower end of the table foot 1, which plays a role in anti-slip and stabilizing the table frame.

[0024] Further, the locking rod passes through the sliding groove 16. Anti-disengagement members 17 are provided at both ends of the locking rod 12 extending outside the sliding groove 16, so that the locking rod 12 can only move horizontally in the sliding groove 16.

[0025] Further, the table leg 1 has a hollow structure. Refer to Figures 1 to 7 , the hinge shaft is connected to a pressing member 14. A pressing opening 19 for the pressing member 14 to extend out is provided at the lower end of the table leg 1, hiding the connection structure between the table leg 2 and the table leg 1, and the pressing member facilitates the pressing operation of the user.

[0026] During installation, align the locking hook 21 at the lower end of the table leg 2 with the positioning groove at the upper end of the table leg 1 and insert it. At this time, the lower end of the table leg 2 and the upper end of the table leg 1 only abut against each other, and the table leg and the table leg can still be separated; as Figure 3 shown, the pressing member 14 extends out below the table leg 1. The user presses the mutually hinged rotating arm 13 towards the lower end of the table leg by pressing the pressing member 14. The acting forces of the rotating arm 13 on the first locking rod 121 and the second locking rod 122 cause the two locking rods to move away from each other. When the user presses the pressing member 14 until the hinge shaft is above the plane where the center lines of the first locking rod 121 and the second locking rod 122 are located, stop pressing. The two locking rods experience a process of first moving away and then approaching. The pulling force exerted by the elastic connecting member 15 on the two locking rods pulls the two locking rods towards the direction of approaching each other. Since the locking rods are also restricted by the mutually hinged rotating arm 13, therefore, the two locking rods exert a squeezing force on the end of the locking hook 21 located in the table leg 1, and then the two locking rods are locked with the locking hook 21 to prevent the table leg 2 from detaching from the table leg 1. At this time, the pressing member 14 is located in the pressing opening 19 and basically covers the entire pressing opening.
