Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a shaft yoke comprises a middle paint spraying part 1, wherein an end mounting part 2 is fixedly arranged at one end of the middle paint spraying part 1, the end mounting part 2 and the middle paint spraying part 1 are coaxially arranged, and the end mounting part 2 is arranged in a stepped manner. The middle part 1 that sprays paint keeps away from 2 one ends of tip installation department and has set firmly middle part installation department 3, and middle part installation department 3 and the 1 copper coaxial setting of middle part portion of spraying paint. The dark installation department in middle part is kept away from 1 one end of middle part portion of spraying paint and is set firmly tip portion 4 of spraying paint, and 4 length direction in tip portion 4 of spraying paint is parallel with 3 length direction in middle part installation department.

Referring to fig. 2 and 4, for the utility model discloses a shaft yoke protection architecture that sprays paint, locate tip protection sleeve 5 of tip installation department 2 including one end opening and cover, wherein tip protection sleeve 5's inside shape and tip installation department 2's outside shape looks adaptation, tip protection sleeve 5 open end inner wall is coaxial to be set firmly rubber sleeve 6, 6 outer walls of rubber sleeve and 5 inner wall laminating adaptations of tip protection sleeve. Four fixture blocks 7 are fixedly arranged on the outer wall of the rubber sleeve 6 close to the opening of the end protective sleeve 5 around the axis of the rubber sleeve 6, and the four fixture blocks 7 are arranged at equal angles along the circumferential direction of the rubber sleeve 6. The inner wall of the end protective sleeve 5 is provided with a clamping groove 8 matched with the clamping block 7 in a clamping manner at the position of the clamping block 7. Inside and the 2 outside laminating adaptations of tip installation department of tip protective sheath 5 can make the difficult swing of tip protective sheath 5, and 7 joints of fixture block can make rubber sleeve 6 be connected more firm with tip protective sheath 5 in draw-in groove 8 simultaneously.

Referring to fig. 3 and 4, the end protection sleeve 5 is close to 6 pot heads of rubber sleeve and is equipped with rotary drum 9 and keeps away from 6 one end of rubber sleeve and 5 outer wall threaded connection of end protection sleeve, and wall groove 10 has all been seted up in four fixture block 7 positions department to the 9 inner walls of rotary drum, and 10 openings in wall groove set up around the rotary drum 9 axis, and wall groove 10 bottom is the inclined plane setting and is perpendicular with the rotary drum 9 lateral wall. All be provided with locking structure in four fixture block 7 positions between rotary drum 9 and the rubber sleeve 6 department, locking structure is including setting up the butt pole 11 between wall groove 10 and fixture block 7, and wherein, 11 length direction of butt pole are perpendicular with the axis of tip protective sheath 5. One end of the abutting rod 11, far away from the wall groove 10, penetrates through the end protection sleeve 5, extends into the clamping groove 8 and abuts against one end of the clamping block 7, far away from the rubber sleeve 6. The other one end of butt-joint pole 11 is stretched into in the wall groove 10 and the tip has set firmly hemisphere piece 12, and hemisphere piece 12 is kept away from butt-joint pole 11 one end and is set up for the curved surface, and 11 one end butt wall groove 10 bottoms of butt-joint pole are kept away from to hemisphere piece 12, and butt-joint pole 11 can slide in wall groove 10 along with the hemisphere, and the length of wall groove 10 bottom along rotary drum 9 axis equals the twice of the fast sphere diameter of hemisphere. The outer wall of the end protective sleeve 5 is provided with a cylindrical sinking groove 13 at the position of the abutting rod 11, wherein the diameter of the shaft of the sinking groove 13 is larger than the diameter of the hemispherical block 12, and the abutting rod 11 is externally provided with a spring 14 between the bottom end of the hemispherical block 12 and the sinking groove 13. When the rotating drum 9 is rotated, the inclined surface at the bottom end of the wall groove 10 forces the abutting rod 11 to slide towards the clamping block 7 so as to abut against the clamping block 7, so that the rubber sleeve 6 and the end mounting part 2 are more stable.

Referring to fig. 3 and 5, the paint spraying protection structure for the shaft fork further comprises a middle protection sleeve 15 for protecting the middle installation part 3, the middle protection sleeve 15 comprises two half-ring sleeves 16, ring openings of the two half-ring sleeves 16 are arranged oppositely, rubber pads 17 matched with the half-ring sleeves are fixedly arranged on the inner walls of the half-ring sleeves 16, side plates 18 are fixedly arranged on two sides of each half-ring sleeve 16, and end faces of the two side plates 18 are located on the same horizontal plane. A fixing structure is arranged between the side plates 18 corresponding to the two half-ring sleeves 16, the fixing structure comprises fixing screw rods 19, through holes 20 penetrating through the side plates 18 and nuts 21, the through holes 20 on the two opposite side plates 18 are arranged oppositely, the fixing screw rods 19 sequentially penetrate through the two opposite through holes 20, and the end parts of the fixing screw rods are in threaded connection with the nuts 21. By the cooperation of the fixing screw 19 and the nut 21, the two half ring plates can be fixed to each other when the nut 21 is tightened, and the half ring plates can be abutted against the middle mounting portion 3.

The implementation principle and the beneficial effects of the embodiment are as follows: locate tip installation department 2 with tip protective sheath 5 cover on and make tip protective sheath 5 can cover tip installation department 2 completely, rotate rotary drum 9 this moment, the hemisphere slides in being faster than wall groove 10, and then drives the pole 11 that butts and slides in wall groove 10, and the inclined plane of wall groove 10 bottom forces the pole 11 that butts to slide towards fixture block 7 this moment. After the end protection sleeve 5 is installed, the two half-rings 16 are attached to the outer wall of the middle installation part 3, and the fixing screw 19 penetrates through the through hole 20 and then the end part is in threaded connection with the nut 21.

When tip installation department 2 was located to tip protective sheath 5 cover, rotated rotary drum 9, made the cooperation of butt pole 11 through the inclined plane of wall groove 10 bottom and butt pole and supported tight fixture block 7 by 11 tip, and then can make rubber sleeve 6 hug closely with tip installation department 2 surface, made rubber sleeve 6 difficult emergence not hard up, made tip protective sheath 5 difficult emergence not hard up simultaneously, made tip protective sheath 5 more firm with tip installation department 2's cooperation. When the end protection sleeve 5 needs to be taken down, the rotary drum 9 is rotated reversely, at the moment, the abutting rod 11 is forced to slide back to the clamping block 7 under the action of the elastic force of the spring 14, and then the end protection sleeve 5 can be taken down conveniently. The fit of the fixing screw 19 and the nut 21 can fix the two half-rings 16, and at the same time, the half-rings 16 can be tightly attached to the surface of the middle mounting part 3, thereby protecting the middle mounting part 3.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
