Referring to fig. 3 to 5, the movable body 3 includes a movable base 33, and the movable base 33 has a plurality of cavities for accommodating the self-closing mechanism 4 and the pressure adjusting device 5. The moving base 33 is provided with a through hole opposite to the connecting shaft, and the through hole is used for hinging the third linkage block 23. The end of the third linkage block 23 close to the movable body 3 is provided with two support arms, and is hinged on the movable base 33 through a connecting shaft.
A sliding block 44 is slidably assembled at a position opposite to the fourth linkage block 24 in the moving body 3, and a limit groove for the sliding block 44 to slide along the depth direction is arranged on the inner wall of the moving body 3. Referring to fig. 6, a U-shaped notch is formed in the middle of the sliding block 44, and two opposite through holes are formed in two side walls of the U-shaped notch for being hinged to the end of the fourth linking block 24 through a connecting shaft. When the door is opened and closed, the sliding block 44 is driven by the fourth linkage block 24 to slide along the depth direction of the moving body 3. Drawing (A)
One side of the sliding block 44 is a straight surface and abuts against the side wall of the moving base 33, and a first bearing 32 is further provided between the side wall of the moving base 33 and the sliding block 44 to improve the sliding efficiency of the sliding block 44. The other side of the sliding block 44, i.e. the side close to the pressure regulating device 5, is provided with a track straight surface 441 and a track inclined surface, the track inclined surface is inclined towards the inner side of the sliding block 44, and the track inclined surface is used for cooperating with an elastic component in the self-closing mechanism 4 to drive the sliding block 44 to slide towards the inner side of the motor body 3, so as to drive the door hinge to close. In this embodiment, two track slopes, namely, a first track slope 442 and a second track slope 443, are provided in this order in the depth direction. The first track inclined plane 442 and the track straight plane 441 form an included angle alpha1The angle between the second inclined track surface 443 and the straight track surface 441 is alpha2And α is1<α2. The straight track surface 441, the first track inclined surface 442 and the second track inclined surface 443 are designed to be a rounded arc adjacent to each other, so that the self-closing mechanism 4 can roll thereon. Wherein alpha is not less than 9 degrees1<45°，24°≤α2≤45°。
The fixed base fixing block 12, the first linkage block 21, the second linkage block 22, the third linkage block 23, the fourth linkage block 24, the sliding block 44 and the movable base 33 are hinged by adopting a connecting shaft mode, and in order to avoid friction between adjacent structures, a shaft sleeve is further sleeved on the connecting shaft at the hinged position.
The self-closing mechanism 4 is disposed in the movable body 3, and referring to fig. 3, the self-closing mechanism 4 includes an elastic member 41, a spring slider 42, and a second bearing 43. The elastic member 41 is provided along the longitudinal direction of the motor body 3, and has one end abutting against the pressure adjusting device 5 and the other end provided with a spring slider 42. The spring slider 42 has a U-shaped configuration, and the other end of the elastic member 41 abuts against the inner wall of the spring slider 42. The end of the spring slider 42 remote from the elastic member 41 is hinged with a second bearing 43, said second bearing 43 abutting on the side of said slider 44. When the door hinge is in a fully opened state, the sliding block 44 is located at a side close to the outer end of the movable body 3, the second bearing 43 abuts against the track straight surface 441, when the door hinge is closed, the sliding block 44 gradually slides towards the inside of the movable body, when the second bearing 43 abuts against the first track inclined surface 442, an acting force applied to the sliding block 44 by the elastic member 41 has a component force along the depth direction, the sliding block 44 can be driven to continuously slide towards the inside of the movable body 3, so that the door hinge is driven to be automatically closed, an opening angle of the door hinge is an angle at which the door hinge can be automatically closed, and the size of the angle can be adjusted by adjusting the initial position of the first track inclined surface 442. The elastic member 41 is an energy storage spring in this embodiment, but it is needless to say that other elastic members such as a cylinder which has a resilient force after compression may be used.
The pressure adjusting device 5 is arranged between the elastic member 41 and the inner wall of the power machine body 3, and has the function of adjusting the elastic force of the elastic member 41, thereby adjusting the power of the self-closing mechanism 4. Referring to fig. 3 and 5, the pressure adjusting device 5 includes a first slide block 51, a second slide block 52, and a screw 53. Wherein, the first slide block 51 is slidably assembled in the power machine body 3 and can slide along the extension and contraction direction of the self-closing mechanism 4. One end of the first slider 51 is provided with a groove for accommodating the power storage spring, the power storage spring abuts against the inner wall of the groove, and the other end of the first slider 51 is provided with a first inclined surface 54.
The second slider 52 is slidably fitted in the motor body 3 in a sliding direction perpendicular to the expansion and contraction direction of the self-closing mechanism 4, i.e., in the depth direction of the motor body 3. A second inclined surface 55 abutting against the first inclined surface 54 is provided on a side surface of the second slider 52. The screw 53 is screwed on the side wall of the movable body 3, and one end thereof is rotatably connected with one end of the second slide block 52 far away from the first slide block 51. When the self-closing mechanism is used, the rotating screw 53 can drive the second sliding block 52 to slide, and further drive the first sliding block 51 to slide along the length direction of the power storage spring, so that the length of the power storage spring is changed, namely the pressure of the power storage spring is changed, and further the pressure of the self-closing mechanism is adjusted, so that the self-closing mechanism is suitable for door bodies with different weights, and the door bodies can be closed stably.
Specifically, one end of the screw 53 is provided with a connecting portion 56, one end of the second slider 52 is provided with a limiting groove 57 for accommodating the connecting portion 56, and the connecting portion 56 is clamped in the limiting groove 57, so that the connecting portion 56 can only rotate around the axial direction of the screw 53. In this embodiment, the connecting portion 56 is shaped like a round cake, and the limiting groove 57 is a strip groove, and the opening of the side edge thereof is smaller than the outer diameter of the connecting portion 56, so that the connecting portion 56 is caught in the limiting groove 57 and prevented from being displaced in the axial direction of the screw 53 in the limiting groove 57. In other embodiments, the connecting portion 56 may be spherical, and may also serve to rotatably connect the screw 53 and the second slider 52 together.
When the side wall of the moving body 3 is thick, the outer end of the screw 53 can be arranged to be flush with the outer side wall of the moving body 3, and when the side wall of the moving body 3 is thin, the outer end of the screw 53 can be exposed outside the moving body 3, at this time, a fixed body through hole 15 for accommodating the exposed section of the screw 53 needs to be arranged on the side wall of the fixed body 1, so that the screw 53 is prevented from touching the fixed body 1 when the door hinge is closed.
Further, since the other end of the first slider 51 is provided with the first inclined surface 54, the first inclined surface 54 may abut against the inner wall of the motor body 3 when the first slider 51 slides, and therefore the motor body through hole 31 is opened in the side wall of the motor body 3. When the first slider 51 slides to the end far away from the self-closing mechanism, the end with the first inclined surface 54 can penetrate into the through hole 31 of the power body, so as to ensure that the first slider can slide smoothly.
In order to ensure that the first slider 51 can slide only in the expansion and contraction direction of the self-closing mechanism 4, a first guide groove 34 is further provided in the motor body 3, the first guide groove 34 is provided along the longitudinal direction of the motor body 3, and a side surface of the first slider 51 abuts against a side surface of the first guide groove 34. Meanwhile, a second guide groove 35 is further provided in the movement body 3, the second guide groove 35 is provided in the depth direction of the movement body 3, and both sides of the second slider 52 abut against the second guide groove 35, ensuring that the second slider 52 can only slide in the depth direction of the movement body 3.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
