Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and particularly relates to a lifting and adjustable inner and outer angle structure. Background Technique

[0002] A hinge, also known as a hinge joint, is a mechanical device used to connect two solids and allow relative rotation between them. A hinge can be composed of movable components or foldable materials. The disadvantages are as follows: The lifting structure is hidden inside. In the process of lifting and the state of opening the door, the internal lifting structure of a conventional lifting hinge can be seen, causing relatively large defects in appearance; the closing angle can be adjusted, but a conventional lifting hinge does not have the function of adjusting the closing angle; the hinge can be opened and closed inside and outside, but a conventional lifting hinge can only close the door in one direction.

[0003] Therefore, a hidden adjustable lifting structure of a hinge with the publication number of "CN213477963U" includes a movable clamp seat. A clamping plate assembly is installed on one side of the movable clamp seat, a rotating core is installed in the middle of the movable clamp seat, a lifting sleeve assembly is installed in the rotating core, a rotating shaft is installed in the lifting sleeve assembly, and a mounting plate is arranged on one side of the lifting sleeve assembly. Compared with the prior art, the beneficial effects of the utility model are as follows: The structure of the utility model is simple and novel. Some advantages of the structure of the utility model in terms of function are relatively obvious. Advantage one: The lifting structure is hidden inside. In the process of lifting and the state of opening the door, the internal lifting structure of a conventional lifting hinge can be seen, causing relatively large defects in appearance. Because the lifting structure of the new utility model is covered by a decorative sleeve, the internal structure cannot be seen during the lifting process in the state of opening the door, making the appearance effect of the entire hinge very good.

[0004] However, for the above-mentioned hidden adjustable lifting structure of the hinge, although the rotating shaft passes through the lower end hole of the clamp seat and then passes through the middle hole of the rotating core to connect the whole part in series, and then the adjustable lifting sleeve is pushed into the upper end hole of the clamp seat and fixed with two fastening screws, so that the adjustable lifting sleeve is fixed with the clamp seat part. There are still the following obvious defects in the use process: The adjustable lifting sleeve and the lifting sleeve in the above-mentioned adjustment structure realize the lifting and inner and outer angle adjustment of the hinge. However, after the hinge is adjusted, the adjustable lifting sleeve needs to be locked and fixed by fastening screws, and the hinge cannot be adjusted in terms of lifting and angle anymore. Instead, the fastening screws need to be disassembled and assembled continuously to perform angle and lifting adjustments. Content of the Utility Model

[0005] The purpose of the utility model is to provide a lifting and adjustable inner and outer angle structure to solve the problems raised in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solutions: A lifting and internal and external angle adjustable structure, comprising:

By using the lifting angle arc surface on the rotating adjustment shaft cam, the special-shaped rotating shaft sleeve A and the special-shaped rotating shaft sleeve B are pushed relative to each other for lifting and adjustment of the internal and external angles. After the hinge is adjusted, the shaft limit groove and the shaft limit outer convex block can be used to limit the special-shaped rotating shaft sleeve A and the special-shaped rotating shaft sleeve B after adjustment. And it can be rotated from small to large according to the angles of the rotating adjustment cams on the special-shaped rotating shaft sleeve A and the special-shaped rotating shaft sleeve B, so as to realize the adjustment of different angles and heights of the hinge, and adjust the door body to a suitable position angle for opening and closing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-7 , the present utility model provides a technical solution: a lifting and adjustable internal and external angle structure, including:

[0025] A movable clamp seat 1, on the upper end surface of the movable clamp seat 1, there is a hinged installation cavity 2, which enables the rotating core shaft seat 13 to be connected inside the hinged installation cavity 2 for angular rotation. At the port position of the hinged installation cavity 2, there is a hinge installation frame 3 extending upward, so that the rotating core shaft seat 13 is movably hinged through the hinge installation frame 3. On both inner side walls of the hinge installation frame 3, there are hinge shaft holes 4 for the lifting adjustment shaft member to rotate, enabling the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 to be combined inside the hinge shaft holes 4 for rotation-guided lifting adjustment. On the inner side of the hinge shaft hole 4 on one side inside the hinge installation frame 3, there are shaft limit grooves 12 extending in two directions, which can limit one end of the special-shaped rotating shaft sleeve A7 inside the hinge shaft hole 4 to ensure the stability of the special-shaped rotating shaft sleeve A7 during lifting.

[0026] An installation hinge plate 5, on the arc-shaped concave surface at one end of the surface of the installation hinge plate 5, there is a rotating core shaft seat 13. The rotating core shaft seat 13 enables the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 to be combined and inserted into the core shaft hinge hole 6 to be connected with the installation hinge plate 5. One end of the rotating core shaft seat 13 is provided with a core shaft hinge hole 6. The special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 that are movably hinged with the hinge shaft hole 4 are inserted through both ends of the core shaft hinge hole 6, realizing the functions of lifting and adjustable internal and external angles of the hinge. The outside of the rotating core shaft seat 13 is covered with a U-shaped hinge decoration frame 14, which plays a role in protecting the rotating core shaft seat 13 after angle adjustment.

[0027] On the opposite side of the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8, there is a rotating adjustment cam 9 for lifting and internal and external angle adjustment, which can enable the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 to be adjusted in lifting through the radian of the lifting adjustment angle on the rotating adjustment cam 9 in a state of mutual rotation. On both sides of one end of the special-shaped rotating shaft sleeve A7, there are shaft limit outer protrusions 10 that are adaptively combined with the shaft limit grooves 12, which play a role in limiting the special-shaped rotating shaft sleeve A7 during the rotation of the hinge and prevent the special-shaped rotating shaft sleeve A7 from shifting in position during lifting. One end of the special-shaped rotating shaft sleeve A7 is movably limited in the hinge shaft hole 4 with a leading shaft limit groove 12.

[0028] The special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 enable the hinge to rotate smoothly through the combination of the rotating adjustment cam 9. One end of the rotating shaft of the special-shaped rotating shaft sleeve B8 is movably installed in the hinge shaft hole 4 on the other side inside the hinge installation frame 3. The hinge clamping plate member 11 is installed at the end of the movable clamping seat 1, and the U-shaped slot provided on the hinge clamping plate member 11 is clamped outside the rotating core shaft seat 13. The rotating core shaft seat 13 is movably arranged inside the hinge installation frame 3 through the combination of the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 to rotate for adjusting the internal and external angles of lifting and lowering.

[0029] Specifically, during use, when the glass is installed on the hinge and the closing angle of the glass is not the ideal angle, the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 can form a misaligned rotation through the arc-shaped angle surfaces, enabling the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 to move up and down. Then, the glass cabinet door can be rotated to a suitable opening angle through the adjustment of the internal and external angles of lifting and lowering, so as to obtain the ideal opening and closing angle of the glass door. When the movable clamping seat 1 is rotated, since the movable clamping seat 1 is connected to the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8, the special-shaped rotating shaft sleeve A7 and the special-shaped rotating shaft sleeve B8 rotate accordingly. The rotating core shaft seat 13, the special-shaped rotating shaft sleeve B8, and the installation hinge plate 5 are connected and fixed. The special-shaped rotating shaft sleeve A7 is in the lowest point matching state with the special-shaped rotating shaft sleeve B8 in the closed state. When rotating, the special-shaped rotating shaft sleeve A7 forms a misalignment depending on the matching inclined plane with the special-shaped rotating shaft sleeve B8. The greater the misalignment during rotation, the higher the rising height. When lifting and lowering, the hinge decorative frame 14 is pushed by the movable clamping seat 1 and rises accordingly, and also descends when descending. Therefore, the internal structure cannot be seen during the lifting and lowering process, thus realizing the lifting and lowering of the hinge and the adjustment of the internal and external angles.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
