Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a hinge structure that opens and closes with a lifting mechanism. Background Technology

[0002] Shower room: A separate shower enclosure. Modern homes have increasingly higher requirements for bathroom facilities, and many families hope to have a separate bathing space. However, due to the limited space in the living room, the bathing facilities and sanitary ware can only be placed in one room.

[0003] The shower room makes full use of a corner of the room, clearly delineating the shower area with a fence to form a relatively independent bathing space.

[0004] Currently, shower doors are designed to ensure dry and wet separation, with the door fitting snugly against the floor or door frame. This can easily cause wear and tear on the door frame or door body when opening and closing. Utility Model Content

[0005] (I) Problems to be solved

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a hinge structure that can lift and open while ensuring the function of the door and facilitating its opening and closing.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a hinge structure for lifting and opening, including a shaft core and an outer ring that is rotatably sleeved with the shaft core. The upper and lower ends of the inner wall of the outer ring are both engaged with moving wheels, and two sets of fixed wheels are fixed on the shaft core corresponding to the positions of the two sets of moving wheels.

[0009] Two sets of V-shaped grooves are recessed on the adjacent surfaces of the moving wheel and the fixed wheel;

[0010] When the hinge is in the extended position:

[0011] The V-grooves of the upper moving wheel and the fixed wheel are positioned correspondingly, while the V-grooves of the lower moving wheel and the fixed wheel are offset.

[0012] The top and bottom of the shaft are connected to a first hinge, and the outer ring is connected to a second hinge at the end away from the first hinge. The first hinge has a slot that matches the height of the shaft.

[0013] As an improvement, the first hinge includes a first inner shell and a first outer shell, which are fixed together by bolts.

[0014] As an improvement, the second hinge includes a second inner shell and a second outer shell, with the second inner shell being fixed to the first outer shell by bolts.

[0015] As an improvement, the inner wall of the outer ring is provided with a shaft hole that can accommodate the drive wheel, and a locking groove is provided on both sides of the shaft hole. The outer wall of the drive wheel has a locking wing that mates with the shaft groove.

[0016] As an improvement, an outer protective sleeve is also fitted around the outer outer ring. The top and bottom of the outer protective sleeve are rotatably fitted with two sets of fixed wheels. An opening is provided on the outer protective sleeve near the second hinge. The side wall of the outer outer ring passes through the opening and is fixedly connected to the second outer shell.

[0017] (III) Beneficial Effects

[0018] The advantages of this utility model compared with the prior art are as follows: In this application, the height of the second hinge is controlled by cooperating with the shaft core and the moving wheel of the hinge structure during opening and closing rotation, thereby controlling the height of the door body, reducing resistance and friction during opening and closing, and facilitating operation and use.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] Please refer to the appendix carefully. Figure 1-5 A hinge structure for lifting and opening includes a shaft core 1 and an outer ring 2 that is rotatably sleeved with the shaft core 1. The upper and lower ends of the inner wall of the outer ring 2 are both engaged with moving wheels 3. Two sets of fixed wheels 4 are fixed on the shaft core 1 corresponding to the positions of the two sets of moving wheels 3.

[0031] The adjacent surfaces of the moving wheel 3 and the fixed wheel 4 are each provided with two sets of V-shaped grooves 5, which are used to control the position of different hinge connectors during rotation.

[0032] In practical use:

[0033] When the hinge is in the extended position:

[0034] The upper moving wheel 3 and the fixed wheel 4 have corresponding V-shaped grooves 5, while the lower moving wheel 3 and the fixed wheel 4 have misaligned V-shaped grooves 5.

[0035] The top and bottom of the shaft core 1 are connected by a first hinge, and the outer ring 2 is connected to a second hinge at the end away from the first hinge. The first hinge is provided with a slot 6 that matches the height of the shaft core 1.

[0036] In one embodiment:

[0037] The first hinge includes a first inner shell 7 and a first outer shell 8, which are fixed together by bolts 9. The second hinge includes a second inner shell 10 and a second outer shell 11, which are fixed together by bolts 9.

[0038] like Figure 2 ,4 As shown, reinforcing plates are bolted to the inner sides of both the first and second hinges to increase their strength.

[0039] In one embodiment:

[0040] The inner wall of the outer ring 2 is provided with a shaft hole 12 that can accommodate the drive wheel 3. The shaft hole 12 has a locking groove 13 on both sides. The outer wall of the drive wheel 3 has a locking wing 14 that protrudes outward from the shaft groove. The linkage control between the drive wheel and the outer ring 2 is completed through the structural cooperation between the locking wing and the locking groove 13, so that the second hinge can be driven to rotate when the door panel rotates, thereby driving the drive wheel to rotate.

[0041] To ensure aesthetics, reduce structural gaps, and guarantee structural stability, an outer protective sleeve 15 is fitted around the outer ring 2. The top and bottom of the outer protective sleeve 15 are rotatably fitted with two sets of fixed wheels 4. An opening 16 is provided on the outer protective sleeve 15 near the second hinge. The side wall of the outer ring 2 passes through the opening 16 and is fixedly connected to the second outer shell 11. When opening and closing, the outer ring moves along the height direction inside the outer protective sleeve 15.
