Detailed Description
Referring to fig. 1, the hinge of the present invention comprises a rotating shaft 1, a fixed blade 2 and a movable blade 3, wherein the rotating shaft 1 sequentially passes through a fixed shaft sleeve 4 of the fixed blade 2 and a movable shaft sleeve 5 of the movable blade 3, one end of the rotating shaft 1 is provided with a clamping head 6 matched with the fixed shaft sleeve 4, and the clamping head 6 is in interference fit with the fixed shaft sleeve 4; and oil grooves 7 are formed in the periphery of the rotating shaft 1 and/or the inner hole of the moving shaft sleeve 5.
In this application, stator blade 2 is provided with three groups of fixed axle sleeve 4, it is provided with two groups of axle sleeves 5 to move blade 3, fixed axle sleeve 4 and axle sleeve 5 are dentate distribution to crisscross meshing. Still include plug 10, plug 10 is provided with block and screw thread portion, plug 10 is used for the upper and lower both ends of shutoff pivot 1, screw thread portion cooperatees with the dead axle sleeve 4 at both ends, and the shutoff is on the upper end of upper portion dead axle sleeve 4 and the lower extreme of lower part dead axle sleeve 4, and plug 10 can effectively have dustproof and shutoff effect to a certain extent concurrently.
Referring to fig. 2 and 4, in the first embodiment of the present application, the outer ring of the chuck 6 is provided with a plurality of straight threads 8 along the axial direction, and the chuck 6 is clamped in the fixed shaft sleeve 4 through the straight threads 8. In the use process, the clamping head 6 is placed at the upper end, so that the rotating shaft 1 cannot fall off due to the fact that the fixing shaft sleeve 4 is not restrained by the self gravity and other structures. Therefore, the design of the straight lines 8 is adopted, so that the clamping head 6 is more easily clamped into the fixed shaft sleeve 4 in the installation process, and the straight lines 8 can be longitudinally cut into the inner wall of the fixed shaft sleeve 4 to prevent the movable blade 3 from driving the rotating shaft 1 to move axially in the later period.
In the present embodiment, the oil grooves 7 are spirally distributed on the outer circumference of the rotating shaft 1 and/or on the inner wall of the inner hole of the moving shaft sleeve 5. By adopting the design, the spiral oil groove 7 is mainly utilized to better provide lubrication for the contact surface which can be contacted with the oil groove, for example, if the oil groove is arranged on the periphery of the rotating shaft 1, the contact surfaces of the movable shaft sleeve 5 and the rotating shaft 1 are in the action range of the oil groove 7 no matter how the movable shaft sleeve is matched with the rotating shaft, and the lubrication effect is better. When the oil groove 7 is arranged on the inner wall of the inner hole of the movable shaft sleeve 5, because the rotating shaft 1 is locked due to the matching of the straight grains 8 and the shaft sleeve 4, the lubricating oil on the oil groove 7 can automatically fill the working surface between the movable shaft sleeve 5 and the rotating shaft 1 due to the rotation of the movable shaft sleeve 5, and the effect is better.
Of course, the oil groove 7 can also be designed in an annular shape in this embodiment, but it will not be described in detail here.
Referring to fig. 3 and 5, of course, in another embodiment of the present application, the outer ring of the chuck 6 is provided with at least one protruding ring 9, and the chuck 6 is clamped in the fixed shaft sleeve 4 through the protruding ring 9. The structural cooperation of bulge loop 9 and fixed axle sleeve 4 hole adopts complete interference fit, and certainly bulge loop 9 not only limits one, and its main objective utilizes bulge loop 9 and fixed axle sleeve 4 interference fit's effort to drive pivot 1 axial force when offsetting movable leaf 3 and rotate, though set up differently with the straight line 8 in last embodiment, but the requirement of assembly has been saved to the easier processing on the whole. Furthermore, for better lubrication, the oil grooves 7 are annularly distributed on the outer circumference of the rotating shaft 1 and/or on the inner wall of the inner hole of the moving sleeve 5. In this embodiment, the protruding ring 9 is not limited to be provided on the chuck 6, and therefore, when the protruding ring 9 is provided, the oil groove 7 is provided in a ring shape, and it is needless to say that the protruding ring 9 and the oil groove 7 are selectively used to lock the entire rotating shaft 1, which can prevent the play problem and can also be lubricated by the lubricating oil in the oil groove 7.
The hinge is provided with the clamping head 6 on the rotating shaft 1, so that the rotating shaft 1 is clamped on the fixed shaft sleeve 4, and the radial force applied to the rotating shaft 1 by the anti-locking shaft sleeve 5 in the rotating process is converted into the axial force, thereby playing the effect of preventing the rotating shaft 1 from moving; because radial friction is applied to the rotating shaft 1, oil grooves 7 are formed in the periphery of the rotating shaft 1 and/or an inner hole of the moving shaft sleeve 5, and the friction between the rotating shaft 1 and the moving shaft sleeve 5 is reduced by using lubricating oil stored in the oil grooves 7, so that the generation of the whole friction is reduced, and the possibility of axial movement of the rotating shaft 1 is further reduced; in addition, because of the existence of the lubricating oil, the relative movement of the rotating shaft 1 and the movable shaft sleeve 5 is smoother, and the noise is smaller.
The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should be all included in the protection scope of the present invention as long as the technical effects are achieved by any of the same or similar means.
