Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge capable of adjusting the angle of a table top and a table. Background Art

[0002] A hinge is a joint used to connect two objects, allowing them to open and close relative to each other. It's a common connecting element in furniture, doors, and windows. Common hinges on the market typically have two leaf plates, secured to the components to be connected via screws or pins. The first leaf plate is attached to the main body of the object, while the second leaf plate is attached to the secondary body. The two leaf plates are pivotally connected, allowing for relative opening and closing.

[0003] In order to maintain a normal visual angle and reduce neck fatigue when the user is working or studying, the hinge can also be used to hinge the desktop and the support frame supporting the desktop, so that the desktop can rotate relative to the desktop. The hinges commonly used on the market for hinged desktops and desktops include two plate-shaped hinges and a shaft. The hinges are provided with holes that match the shafts, and the shafts are inserted into the holes. One hinge is fixed to the bottom surface of the desktop, and the other hinge is fixed to the side of the support frame. Figure 7 As shown, after installation, the hinge is spaced significantly apart from the edge of the tabletop, creating a lever-like structure with the hinge acting as a fulcrum. If the user accidentally applies force to the edge of the tabletop closest to the hinge, the tabletop will rotate relative to the hinge, causing the other side of the tabletop to tilt, making the table structure unstable. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a hinge with adjustable table top angle, the hinge comprising a first hinge, a second hinge and a rotating shaft, the rear ends of the first hinge and the second hinge are rotatably connected by the rotating shaft, the front end of the first hinge, that is, the end away from the rotating shaft, is provided with a first hinge fixing part for fixing the first hinge, so that a distance is left between the rotating shaft and the first hinge fixing part, and by providing the first hinge fixing part, the installation of the first hinge is transferred from the position of the hinge body to the front end of the hinge, so that the first hinge can be installed in the air and support the second hinge so that the rotating shaft can be away from the front end of the first hinge and closer to the edge of the table top; therefore, when the hinge is installed on the table, compared with the prior art, the rotating shaft of the hinge is closer to the edge of the table top, and the user needs to apply a large force to the edge of the table top close to the rotating shaft to make the table top rotate relative to the rotating shaft. The hinge with this special structure can make the overall structure of the table more stable.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A hinge with adjustable table top angle includes a first hinge and a second hinge. The rear ends of the first hinge and the second hinge are rotatably connected via a rotating shaft. The second hinge is provided with a second hinge mounting portion for fixing the second hinge. The front end of the first hinge is provided with a first hinge fixing portion for fixing the first hinge, so that a distance is left between the rotating shaft and the first hinge fixing portion.

[0007] Preferably, the first hinge includes a horizontally arranged first main body portion and longitudinal portions connected to both sides of the first main body portion, and the first hinge fixing portion is connected to the front end of the longitudinal portion.

[0008] Preferably, the first main body is a plate-shaped body, the longitudinal portion is formed by bending both sides of the first main body in the same direction, and the first hinge fixing portion is formed by bending the front end of the longitudinal portion.

[0009] Preferably, the first hinge fixing portion is provided with a through hole for installation, and the first hinge can be installed and fixed by connecting members such as bolts.

[0010] Preferably, a first rotating shaft connecting portion is provided at the rear end of the longitudinal portion of the first hinge; the second hinge includes a horizontally arranged second plate-like body, and the front part of the second plate-like body forms a second hinge mounting portion with a mounting hole, and the rear part of the second plate-like body is bent downward on both sides to form a second rotating shaft connecting portion; the first rotating shaft connecting portion and the second rotating shaft connecting portion are provided with holes that cooperate with the rotating shafts, and the rotating shafts are inserted into the holes to realize the relative rotation of the first hinge and the second hinge.

[0011] Preferably, the length of the second hinge is shorter than that of the first hinge in the horizontal direction, a first hinge fixing portion is provided at the front end of the first hinge, and the rear end of the first hinge is rotatably connected to the rear end of the second hinge via a rotating shaft. In order to avoid the second hinge interfering with the installation and fixation of the first hinge, the length of the second hinge is shorter than that of the first hinge.

[0012] Preferably, arc-shaped notches are provided at the front and rear ends of the first main body. The notches can help the second hinge to rotate more flexibly, avoid collision or jamming, and improve the convenience and flexibility of the hinge.

[0013] Preferably, the second hinge mounting portion is provided with a through hole for mounting and fixing.

[0014] Preferably, when the first hinge and the second hinge are aligned, the second hinge mounting portion is placed on the upper surface of the longitudinal portion, and the second hinge mounting portion is divided into an inner portion and an outer portion with the longitudinal portion as the boundary. The inner portion is opposite to the first main body portion, and a through hole for installation is provided on the outer portion. This design can facilitate the installation and fixation of the second hinge and prevent the first main body portion from interfering with the installation of the second hinge.

[0015] A table with a rotatable table top, comprising the above-mentioned hinge with an adjustable table top angle, a rotatable table top and a support frame for supporting the table top; a first hinge fixing portion is fixed to the side of the support frame, and a second hinge mounting portion is fixed to the corresponding edge of the bottom surface of the table top; and the rotating shaft located at the rear end of the hinge is closer to the edge of the table top than the first hinge fixing portion located at the front end of the hinge; after installation, the table top can be rotated around the rotating shaft relative to the support frame. Due to the use of a hinge with a special structure, on the one hand, the user can easily adjust the angle of the table top to meet different usage requirements and comfortable angles. On the other hand, when there is no need to adjust the table top angle and the table top is set horizontally, the user needs to apply a large force to the edge of the table top close to the rotating shaft to rotate the table top relative to the rotating shaft, making the table more stable.

[0016] The principle and beneficial effects of the present invention using the above technical solution are:

[0017] 1. The utility model includes a first hinge, a second hinge and a rotating shaft. The rear ends of the first hinge and the second hinge are rotatably connected via the rotating shaft. The second hinge is provided with a second hinge mounting portion for fixedly mounting the second hinge. The front end of the first hinge, that is, the end away from the rotating shaft, is provided with a first hinge fixing portion for fixedly mounting the first hinge, so that a distance is left between the rotating shaft and the first hinge fixing portion. By providing the first hinge fixing portion, the installation of the first hinge is transferred from the position of the hinge body to the front end of the hinge, so that the first hinge can be installed in the air and supports the second hinge, so that the rotating shaft can be away from the front end of the first hinge and closer to the edge of the table top.

[0018] 2. The hinge of the present invention can be used to realize the rotatable function of the table top. Compared with the hinge used in the angle-adjustable table in the prior art, the hinge proposed by the present invention has a rotating shaft closer to the edge of the table top. In short, the table top is regarded as a lever and the rotating shaft as a fulcrum. The rotating shaft of the hinge is closer to the edge of the table top, that is, compared with ordinary hinges, the lever arm is reduced. In this way, the user needs to apply a greater force to the edge of the table top close to the rotating shaft to make the table top rotate relative to the rotating shaft. The hinge with this special structure can make the overall structure of the table more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] The specific implementation of the utility model is as follows:

[0030] refer to Figures 1-6 , this embodiment first provides a hinge with adjustable table top angle, including a first hinge 1 and a second hinge 2. The rear ends of the first hinge 1 and the second hinge 2 are rotatably connected via a rotating shaft 3. The second hinge 2 is provided with a second hinge mounting portion 22 for fixing the second hinge 2. The front end of the first hinge 1 is provided with a first hinge fixing portion 12 for fixing the first hinge 1. The part for fixing the hinge is set at the front end of the hinge, and the part for enabling the hinge to rotate is set at the rear end of the hinge, so that a distance is left between the rotating shaft 3 and the first hinge fixing portion 12.

[0031] Further, if Figure 2 As shown, the first hinge 1 includes a horizontally arranged first main body portion 13 and longitudinal portions connected to both sides of the first main body portion 13 , and the first hinge fixing portion 12 is connected to the front end of the longitudinal portion.

[0032] More specifically, the first main body 13 is a plate-shaped body. As an implementation case, the longitudinal portion is formed by bending both sides of the first main body 13 in the same direction, and the first hinge fixing portion 12 is formed by bending the front end of the longitudinal portion; as another implementation case, the longitudinal portion is welded to both sides of the first main body 13, and the first hinge fixing portion 12 is welded to the front end of the longitudinal portion.

[0033] Please refer to Figure 1-2 The first hinge fixing portion 12 is provided with a through hole 221 for installation, and the first hinge 1 can be installed and fixed by connecting members such as bolts.

[0034] Furthermore, a first rotating shaft connecting portion 11 is provided at the rear end of the longitudinal portion of the first hinge 1; the second hinge 2 includes a horizontally arranged second plate-like body 23, and the front part of the second plate-like body 23 forms a second hinge mounting portion 22 with a mounting hole, and the rear part of the second plate-like body 23 is bent downward on both sides to form a second rotating shaft connecting portion 21; the first rotating shaft connecting portion 11 and the second rotating shaft connecting portion 21 are provided with holes that cooperate with the rotating shaft 3, and the rotating shaft 3 is inserted into the hole to realize the relative rotation of the first hinge 1 and the second hinge 2.

[0035] like Figure 1 As shown, in the horizontal direction, the length of the second hinge 2 is shorter than that of the first hinge 1, a first hinge fixing portion 12 is provided at the front end of the first hinge 1, and the rear end of the first hinge 1 is rotatably connected to the rear end of the second hinge 2 through a rotating shaft 3. In order to avoid the second hinge 2 interfering with the installation and fixation of the first hinge 1, the length of the second hinge 2 is shorter than that of the first hinge 1.

[0036] Specifically, arc-shaped notches 131 are provided at the front and rear ends of the first main body 13. The notches 131 can help the second hinge 2 rotate more flexibly, avoid collision or jamming, and improve the convenience and flexibility of the product.

[0037] Furthermore, the second hinge mounting portion 22 is provided with a through hole 221 for installation and fixation. When the first hinge 1 and the second hinge 2 are aligned, the second hinge mounting portion 22 is placed on the upper surface of the longitudinal portion. With the longitudinal portion as the boundary, the second hinge mounting portion 22 is divided into an inner portion 22a and an outer portion 22b. The inner portion 22a is opposite to the first main body portion 13, and a through hole 221 for installation is provided on the outer portion 22b. This design can facilitate the installation and fixation of the second hinge 2 and prevent the first main body portion 13 from interfering with the installation of the second hinge 2.

[0038] In some embodiments of the present application, Figure 1-2As shown, the shaft 3 is a rivet, and a limit portion 31 is formed at both ends to prevent the shaft 3 from falling out of the hinge. The rivet is not only quick and easy to install, but also has high tensile strength and torsional strength, which can ensure that the connection between the first hinge 1 and the second hinge 2 is firm and reliable.

[0039] Specifically, the first hinge 1, the second hinge 2, and the rotating shaft 3 are assembled as follows: the first rotating shaft connecting portion 11 of the first hinge 1 is aligned with the second rotating shaft connecting portion 21 of the second hinge 2, so that the holes therein correspond. The rotating shaft 3 is inserted into the holes, ensuring that the rotating shaft 3 is securely installed to achieve relative rotation between the first hinge 1 and the second hinge 2. The second hinge mounting portion 22 is placed on the upper surface of the longitudinal portion of the first hinge 1, so that the inner portion 22a of the second hinge mounting portion 22 is opposite the first main body portion 13.

[0040] Furthermore, the hinge can be used on a table after being assembled, so that the table can realize the function of adjusting the angle of the table top. Therefore, this embodiment also proposes a table with a rotatable table top, including the above-mentioned hinge with adjustable table top angle, a rotatable table top 200 and a support frame 300 for supporting the table top; the first hinge fixing portion 12 is fixed to the side of the support frame 300, and the second hinge mounting portion 22 is fixed to the bottom edge of the corresponding rotatable table top 200; and the rotating shaft 3 at the rear end of the hinge is farther away from the rotatable table top than the first hinge fixing portion 12 at the front end of the hinge. The edge of the board 200 is closer; after installation, the rotatable table top 200 can be rotated around the rotation axis 3 relative to the support frame 300. Due to the use of a hinge with a special structure, on the one hand, the user can easily adjust the angle of the rotatable table top 200 to meet different usage requirements and comfortable angles. On the other hand, when there is no need to adjust the angle of the rotatable table top 200 and the rotatable table top 200 is set horizontally, the user needs to apply a large force to the edge of the rotatable table top 200 close to the rotation axis 3 to make the table top rotate relative to the rotation axis 3, making the table more stable.

[0041] For more details, refer to Figure 3-Figure 4 The hinges are fixed to the support frame 300 and the rotatable table top 200 as follows: This embodiment uses bolts as connecting parts. First, a threaded hole is provided on the side of the support frame 300 at the fixed connection with the first hinge 1, corresponding to the through hole 221 provided on the first hinge fixing part 12. The bolt passes through the through hole 221 and is screwed into the threaded hole to fix the first hinge 1 to the side of the support frame 300; then a threaded hole is also provided on one side of the bottom edge of the rotatable table top 200 at the fixed connection with the second hinge 2, corresponding to the through hole 221 provided on the second hinge mounting part 22. The bolt passes through the through hole 221 and is screwed into the threaded hole to fix the second hinge 2 to the bottom surface of the rotatable table top 200.

[0042] After the hinges are installed, the rotatable tabletop 200 can rotate about the axis 3 relative to the connecting component, allowing the user to manually adjust the angle of the tabletop according to actual needs. To adjust the angle, apply appropriate force to rotate the tabletop about the axis 3 to the desired angle. The hinge's rotating structure ensures smooth rotation of the tabletop. A knob lock device is also connected to the bottom surface of the tabletop to stabilize the tabletop at the adjusted angle.

[0043] like Figure 3-Figure 6 As shown, when the user places the table top horizontally, the second hinge mounting portion 22 of the second hinge 2 rests on the upper surface of the longitudinal portion of the first hinge 1; when the user needs to adjust the angle of the rotatable table top 200, as shown in FIG. Figure 5 As shown, an upward force is applied to the bottom surface of the table top away from the position where the table top is connected to the hinge. Because the table top can be regarded as a lever and the rotating shaft 3 is regarded as a fulcrum, the farther away from the fulcrum, the longer the lever arm is, and the smaller the force required to be applied; after adjusting to the appropriate angle, the angle is fixed by the knob locking device 400 connected to the bottom surface of the table top.

[0044] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
