Technical Field

[0001] The utility model relates to the technical field of visible hinges, in particular to an anti-prying visible hinge. Background Art

[0002] At present, the mainstream visible hinge products on the market install a screw on the hinge panel, and this screw is used as the anti-prying point of the hinge. The size of the screw head is relatively short, and the anti-prying bearing force is correspondingly small, so improvement is needed. Summary of the Invention

[0003] Aiming at the defects in the prior art that the visible hinge installs a screw on the hinge panel for anti-prying, resulting in a small anti-prying bearing force of the visible hinge, etc., the utility model provides a new anti-prying visible hinge.

[0004] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] An anti-prying visible hinge includes a fixed page and a movable page. The movable page is rotationally connected to the fixed page, and the movable page rotates towards or away from the fixed page. A first anti-prying plate extending along the thickness direction of the fixed page is arranged on the fixed page, and a second anti-prying plate extending along the thickness direction of the movable page is arranged on the movable page. A deployed state and a folded state are formed between the movable page and the fixed page. In the folded state, the movable page rotates towards the fixed page until the movable page is attached to the fixed page, and the outer surface of the first anti-prying plate faces the inner surface of the second anti-prying plate.

[0006] In the folded state, the first anti-prying plate and the second anti-prying plate face each other, thus forming an anti-prying structure extending along the thickness direction of the fixed page, improving the anti-prying force that the visible hinge can bear, and improving the anti-prying effect of the visible hinge.

[0007] Preferably, for the above-mentioned anti-prying visible hinge, the side of the fixed page away from the movable page is bent upward to form the first anti-prying plate.

[0008] The edge of the fixed page is bent upward to form the first anti-prying plate, which has the advantages of high structural strength and low cost.

[0009] Preferably, for the above-mentioned anti-prying visible hinge, the movable page includes a first section, a second section and a connecting section. The first section and the second section are respectively arranged at both ends of the connecting section. The second anti-prying plate is arranged at one end of the second section away from the connecting section. The second anti-prying plate faces the connecting section and is parallel to the connecting section. In the folded state, the first section is attached to the fixed page.

[0010] The first section, the second section and the third section form a Z-shaped movable page, improving the structural strength of the movable page.

[0011] Preferably, for the anti-prying visible hinge described above, the length of the first anti-prying plate is 60 cm, the length of the second anti-prying plate is 59 cm, the width of the first anti-prying plate is 9 cm, the width of the second anti-prying plate is 15.5 cm, the length of the fixed page is 140 cm, and the length of the movable page is 139 cm.

[0012] Through the above structure, the anti-prying structure formed by the first anti-prying plate and the second anti-prying plate is rectangular, further improving the anti-prying force that the first anti-prying plate and the second anti-prying plate can withstand, and further improving the anti-prying effect of the visible hinge.

[0013] Preferably, for the anti-prying visible hinge described above, a hollow sleeve is provided on the fixed page, an insertion pipe is provided on the movable page, and a rotating shaft and a damping sleeve are further included. A positioning piece is coaxially provided at one end of the damping sleeve. The sleeve, the damping sleeve, and the insertion pipe are all sleeved on the rotating shaft. The insertion pipes are distributed at both ends of the sleeve. One end of the damping sleeve is inserted into the sleeve, and both sides of the positioning piece are abutted against the sleeve and the insertion pipe respectively.

[0014] One end of the damping sleeve is inserted into the sleeve, improving the stability of the sleeve sleeved on the rotating shaft. The positioning piece is abutted against the insertion pipe and the sleeve respectively, improving the stability of the insertion pipe and the sleeve sleeved on the rotating shaft, and also reducing the sound when the movable page rotates.

[0015] Preferably, for the anti-prying visible hinge described above, the damping sleeve is made of nylon material and glass fiber material.

[0016] The damping sleeve made of nylon material and glass fiber material has the advantages of high strength, strong durability, and quietness. BRIEF DESCRIPTION OF THE DRAWINGS

A second anti-prying plate 21 extending along the thickness direction of the movable page 2 is provided on the movable page 2. An unfolded state and a folded state are formed between the movable page 2 and the fixed page 1. In the folded state, the movable page 2 rotates towards the fixed page 1 until the movable page 2 is attached to the fixed page 1, and the outer surface of the first anti-prying plate 11 faces the inner surface of the second anti-prying plate 21.

[0023] Preferably, the first anti-prying plate 11 is formed by bending the side of the fixed page 1 away from the movable page 2 upwards.

[0024] Preferably, the movable page 2 includes a first section 22, a second section 23, and a connecting section 24. The first section 22 and the second section 23 are respectively arranged at both ends of the connecting section 24. The second anti-prying plate 21 is arranged at one end of the second section 23 away from the connecting section 24. The second anti-prying plate 21 faces the connecting section 24 and is parallel to the connecting section 24. In the folded state, the first section 22 is attached to the fixed page 1.

[0025] Preferably, the length of the first anti-prying plate 11 is 60 cm, the length of the second anti-prying plate 21 is 59 cm, the width of the first anti-prying plate 11 is 9 cm, the width of the second anti-prying plate 21 is 15.5 cm, the length of the fixed page 1 is 140 cm, and the length of the movable page 2 is 139 cm.

[0026] Preferably, a hollow sleeve 12 is provided on the fixed page 1, and an insertion pipe 25 is provided on the movable page 2. A rotating shaft 3 and a damping sleeve 4 are further included. A positioning piece 41 is coaxially arranged at one end of the damping sleeve 4. The sleeve 12, the damping sleeve 4, and the insertion pipe 25 are all sleeved on the rotating shaft 3.
