A kind of blind hinge comprises:
First hinge plate (1), second hinge plate (2) and axle (3);
One side of first hinge plate (1) is that first cylinder (1A) opposite side is first plane (1C), and the arm of first hinge plate (1) is V-arrangement bending (1B);
One side of second hinge plate (2) is that second cylinder (2A) opposite side is second plane (2C);
Axle (3) can pass the concentric drums of first cylinder (1A) and second cylinder (2A) formation.
Preferably, said cylinder is a reel.
Alternatively, two planes of said V-arrangement bending (1B) are 1～1.5 times circular arc connection of blind hinge thickness of slab with the radius of curvature.
Alternatively, have at least two unthreaded holes (2B) on second plane (2C).
Preferably, above-mentioned blind hinge also comprises: have two seats (6) that the plane is relative, one of them plane has and the corresponding screw socket of said two unthreaded holes (2B) at least, the height of said seat (6) more than or equal to the diameter of cylinder and blind hinge thickness of slab and.
Preferably, concentric drums and its two ends of passing first cylinder (1A) and second cylinder (2A) formation, the two ends of said axle (3) have round end.
Alternatively, said first cylinder (1A) has at least 1 groove with second cylinder (2A) cooperation place, forms at least 3 concentric cylinders.
Can find out that from above technical scheme the utility model embodiment has the following advantages: needn't slot, easy for installation, having solved that the cross section that fluting brings is irregular, the fluting edge is uneven and hinge and fluting between slit big problem.
Description of drawings
Fig. 1 is the structural representation of the utility model blind hinge;
Fig. 2 looks sketch map for the master of the utility model blind hinge;
Fig. 3 looks sketch map for the left side of the utility model blind hinge;
Fig. 4 is the sketch map of the installation of the utility model blind hinge when closed;

The specific embodiment
The utility model embodiment provides a kind of blind hinge, sees also Fig. 1～Fig. 5, and wherein Fig. 1 is the structural representation of the utility model blind hinge; Fig. 2 looks sketch map for the master of the utility model blind hinge; Fig. 3 looks sketch map for the left side of the utility model blind hinge; Fig. 4 is the sketch map of the installation of the utility model blind hinge when closed; Sketch map when Fig. 5 opens for the installation of the utility model blind hinge.
The blind hinge that the utility model embodiment provides, as shown in Figure 1, comprising:
First hinge plate (1), second hinge plate (2) and axle (3)
One side of first hinge plate (1) is that first cylinder (1A) opposite side is first plane (1C), and the arm of first hinge plate (1) is V-arrangement bending (1B);
One side of second hinge plate (2) is that second cylinder (2A) opposite side is second plane (2C);
Axle (3) can pass the concentric drums of first cylinder (1A) and second cylinder (2A) formation.
The blind hinge that the utility model provides needn't be slotted, and is easy for installation, having solved that the cross section that fluting brings is irregular, the fluting edge is uneven and hinge and fluting between slit big problem.
Based on consideration easy to process, above-mentioned cylinder can be reel.
Two planes of above-mentioned V-arrangement bending (1B) are that 1～1.5 times circular arc of blind hinge thickness of slab connects with the radius of curvature R.As shown in Figure 4.
Alternatively, have at least two unthreaded holes (2B) on second plane (2C).What provide in the diagram is 4 unthreaded holes (2B), and the number of unthreaded hole (2B) and position can be come to confirm that the utility model will not limit according to the actual requirements.Can pass fixing second hinge plate (2) of unthreaded hole (2B) with screw, in the subsequent installation explanation, can provide more detailed description.
The blind hinge of the utility model aborning straight forming also can be in installation process installation shaft (3); If moulding when producing, so: concentric drums and its two ends that first cylinder (1A) and second cylinder (2A) formation are passed in the two ends of above-mentioned axle (3) have round end.Above-mentioned round end processing mode can be riveting.
More reliable and more stable when making the hinge folding, above-mentioned first cylinder (1A) has at least 1 groove with second cylinder (2A) cooperation place, forms at least 3 concentric cylinders.Among Fig. 1,1 place fluting is arranged on first hinge plate (1), form 2 concentric reels.2 places fluting is arranged on second hinge plate (2), form 3 concentric reels.Need to prove that concrete fluting quantity can come to confirm that the utility model will not limit according to the actual requirements.
As shown in Figure 4, first plane (1C) of first hinge plate (1) can become solder side, adopts welding manner to fix with guard shield door-plate (4).On present (6), seat (6) welds with guard shield frame plate (5) second hinge plate (2) with bolt.Need to prove that seat (6) can not be the novel necessary parts of this use when producing.
It is thus clear that the blind hinge that the utility model provides can also comprise: have two seats (6) that the plane is relative; One of them plane has and the corresponding screw socket of above-mentioned two unthreaded holes (2B) at least, the height of above-mentioned seat (6) more than or equal to the diameter of cylinder and blind hinge thickness of slab and
If the utility model blind hinge is quoted in journey mechanical protection cover door field, can confirm guard shield door opening angle α through the size of a, b, c, d, e among adjustment Fig. 4, the effect after the guard shield door is opened is as shown in Figure 5.Blind hinge is installed in guard shield door (4) and guard shield frame plate (5) inboard, and the erection bolt of blind hinge also is that what see outside is smooth guard shield door (4) and guard shield frame plate (5) in the cover the inside.The utility model has well improved some shortcomings of traditional backflap hinge, and the fluting size is improper during such as installation can form very big slit, and slotting causes that thin plate distortion and panel edges have problems such as burr.The novel blind hinge that provides of this use need not slotted on door-plate, is installed in the guard shield inboard, and cover door is closed the back hinge and do not exposed, and the outside can't see the bolt that hinge is used is installed, and makes guard shield door-plate neat appearance.
More than a kind of blind hinge that the utility model provided has been carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, to sum up, this description should not be construed as the restriction to the utility model.
