The end faces of the first adjustment block 4 and the second adjustment block 5 that are attached to each other are both provided with protrusions protruding towards each other. A fixing screw 7 is provided on the outer end face of the leaf 1 and penetrates through the thickness direction. After the end of the fixing screw 7 passes through the first adjustment block 4 and the second adjustment block 5, it is connected to the third adjustment block 6. An eccentric screw 8 is penetrated along the thickness direction of the adjustment structure 3, and an adjustment hole 101 is opened on the leaf 1 corresponding to the position of the eccentric screw 8.

[0027] As Figures 1 to 4 shown, when the present utility model is in use, there are two leaves 1 arranged along the length direction of the hinge shaft 2. The leaf 1 is connected to the profile assembly 9 through the adjustment structure 3. An installation groove 10 is provided along the length direction of the profile assembly 9. The adjustment structure 3 includes a first adjustment block 4, a second adjustment block 5, and a third adjustment block 6 that are stacked and attached to each other. Among them, the third adjustment block 6 is movably arranged along the length direction of the installation groove 10. By sequentially passing the second fixing screw 702 through the leaf 1, the first adjustment block 4, and the second adjustment block 5, and then screwing the second fixing screw 702, the third adjustment block 6 is fixed in the installation groove 10. Further, by screwing the first fixing screw 701, the leaf 1, the first adjustment block 4, and the second adjustment block 5 are fixed on the third adjustment block 6.

[0028] As Figure 2 shown, further, when the first fixing screw 701 is screwed and fixed to the third adjustment block 6, the leaf 1, the first adjustment block 4, and the second adjustment block 5 are sleeved on the first fixing screw 701 and all have the freedom to move up and down along the length direction of the first fixing screw 701. When it is necessary to adjust the gap between the fan body and the frame body, rotate the eccentric screw 8 along the adjustment hole 101, so that the second adjustment block 5 moves along the length direction of the first adjustment block 4, and the tightening effect is achieved by using the mutually attached inclined surfaces, and the gap between the leaf 1 and the third adjustment block 6 is tightened, so as to achieve the effect of adjusting the gap error between the fan body and the frame body.

[0029] As Figure 4 and Figure 5As shown in the figure, in the hinge structure of the present utility model, on one end face of the blade 1 that fits with the adjusting structure 3, there is a second installation groove 102 adapted to the width dimension of the first adjusting block 4. The second installation groove 102 extends along the length direction of the blade 1. On one end face of the profile assembly 9 facing the direction of the blade 1, there is a first installation groove 10. The adjusting structure 3 is arranged in the gap between the first installation groove 10 and the second installation groove 102. Among them, the third adjusting block 6 is arranged in the first installation groove 10, and the first adjusting block 4 is arranged in the second installation groove 102;

[0030] Further, a second fixing screw 702 is passed through the end face of the blade 1 on the side facing away from the profile assembly 9. There is a threaded hole 601 on the third adjusting block 6, and the threaded hole 601 penetrates along the thickness direction of the third adjusting block 6. In one implementation, when the second fixing screw 702 is screwed and fixed with the third adjusting block 6, after adjusting the hinge to the correct height position, the end of the second fixing screw 702 passes through the threaded hole 601 and abuts against the bottom of the first installation groove 10. The third adjusting block 6 is fixed in the first installation groove 10 by screwing it into the profile assembly 9, and further fixed at a position close to the notch of the first installation groove 10;

[0031] As Figure 2 and Figure 4 shown in the figure, further, in the above solution, the blade 1 is connected to the profile assembly 9 through the adjusting structure 3. There is a first installation groove 10 adapted to the adjusting structure 3 on the profile assembly 9. The third adjusting block 6 is arranged in the first installation groove 10. The two sides of the opening of the first installation groove 10 are clamped in a pincer shape between the third adjusting block 6 and the second adjusting block 5. In one implementation, when the adjusting structure 3 is in a tensioned state, the gap between the second adjusting block 5 and the third adjusting block 6 is reduced, which plays a certain role in clamping and fixing the pincer-shaped opening of the first installation groove 10.

[0032] Further, in the above solution, the fixing screw 7 includes a first fixing screw 701 for connecting and fixing the blade 1 and the third adjusting block 6, and a second fixing screw 702 for connecting and fixing the third adjusting block 6 and the profile assembly 9;

[0033] As Figure 3As shown, in the adjustment structure 3 of the utility model, the adjustment structure 3 includes a first adjustment block 4, a second adjustment block 5 and a third adjustment block 6 which are stacked and fitted together. The third adjustment block 6 is arranged in the installation slot 10, and the first adjustment block 4 is arranged in the installation slot 2 102. The first adjustment block 4 and the second adjustment block 5 are sandwiched between the leaf 1 and the third adjustment block 6. The end of the fixing screw 7 passes through the leaf 1, the first adjustment block 4, the second adjustment block 5 and the third adjustment block 6 in sequence. The fitted end surfaces of the first adjustment block 4 and the second adjustment block 5 are provided with protrusions protruding toward each other. An eccentric screw 8 is penetrated along the thickness direction of the second adjustment block 5. An adjustment hole 101 is opened at the position of the leaf 1 corresponding to the eccentric screw 8. By rotating the eccentric screw 8 in the adjustment hole 101, the second adjustment block 5 is driven to move in the tightening or loosening direction, thereby adjusting the gap between the fan body and the frame body.

[0034] It should be noted that the leaf piece 1, the first adjustment block 4 and the second adjustment block 5 are sleeved on the fixing screw 7 and can all be moved along the height direction of the fixing screw 7. The second adjustment block 5 is driven to move in the tightening direction by rotating the eccentric screw 8, and the protrusion 2 501 moves toward the direction of the protrusion 1 401. The tightening effect is achieved by utilizing the inclined surface 2 502 and the inclined surface 1 402 that fit between the protrusion 2 501 and the protrusion 1 401, thereby adjusting the gap between the first adjustment block 4 and the second adjustment block 5.

[0035] Further, in the above scheme, a threaded hole 601 adapted to the fixing screw 7 is provided along the thickness direction of the third adjusting block 6, and the end of the fixing screw 7 passes through the first adjusting block 4 and the second adjusting block 5 and is connected to the threaded hole 601, and the second adjusting block 5 is provided with a plurality of strip-shaped through holes 503 corresponding to the position of the fixing screw 7, and the length direction of the strip-shaped through hole 503 is aligned with the length direction of the second adjusting block 5, and a movable gap is reserved between the inner surface of the strip-shaped through hole 503 and the fixing screw 7;

[0036] It should be noted that, under the rotation of the eccentric screw 8, the second adjustment block 5 reciprocates in the tightening direction or the loosening direction, and the single movement path length of the second adjustment block 5 does not exceed the width of the active gap reserved between the strip through hole 1 503 and the fixing screw 7.

[0037] Furthermore, in the above scheme, an eccentric screw 8 is passed through the thickness direction of the first adjustment block 4 and the second adjustment block 5, the bottom end face of the first adjustment block 4 is fitted with the top end face of the second adjustment block 5, and there is a gap between the bottom end face of the second adjustment block 5 and the top end face of the third adjustment block 6, thereby forming an adjustment structure 3 with an I-shaped cross-section.

[0038] Furthermore, in the above solution, the second adjusting block 5 is provided with a second strip-shaped through hole 504 corresponding to the position of the eccentric screw 8, and the length direction of the second strip-shaped through hole 504 is aligned with the width direction of the first adjusting block 4.

[0039] It should be noted that the eccentric screw 8 includes an eccentric rod 801 and an eccentric table 802. The eccentric rod 801 penetrates along the thickness direction of the third adjusting block 6, and the eccentric table 802 is arranged in the second strip-shaped through hole 504 in the second adjusting block 5. When it is necessary to adjust the gap between the fan body and the frame body, the eccentric screw 8 is rotated through the adjusting hole 101 on the blade 1, and the eccentric table rotates around the axis of the eccentric rod. By rotating in the second strip-shaped through hole 504, the second adjusting block 5 is pushed to move in the direction of tensioning or loosening;

[0040] Furthermore, in the above solution, the end surface of the first adjusting block 4 facing the second adjusting block 5 is provided with a first convex block 401, the end surface of the second adjusting block 5 facing the first adjusting block 4 is provided with a second convex block 501, the first convex block 401 is provided with a first inclined surface 402 that fits with the second convex block 501 in the direction facing the second convex block 501, and the second convex block 501 is provided with a second inclined surface 502 that matches the first inclined surface 402 in the direction facing the first convex block 401;

[0041] It should be noted that when the eccentric screw 8 is rotated clockwise, the eccentric table pushes the second adjusting block 5 to move in the direction of tensioning, that is, the first adjusting block 4 remains stationary, and the second convex block 501 moves in the direction facing the first convex block 401. After the second convex block 501 fits with the first convex block 401, the second inclined surface 502 fits with the first inclined surface 402, and the first convex block 401 moves along the second inclined surface 502, so that the first adjusting block 4 rises, plays a role in tensioning the blade 1, and thus realizes the adjustment of the gap error between the fan body and the frame body.

[0042] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
