Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-7, a kind of valve handle with self-locking mechanism, including handwheel 1 are please referred to, the adjustable spiral shell of handwheel 1 is rotated
Bar 13 moves up and down, and the material of handwheel 1 offers helicla flute compatible with screw rod 13 for the middle part of steel material and handwheel 1,
The quantity of locating rod 2 is six and the material of locating rod 2 is steel material, and the inner wall of handwheel 1 is fixedly connected with locating rod 2, fixed
Position bar 2 plays the role of limitation, and the top in 2 outside of locating rod is rotatably connected to kelly 3, and kelly 3 is played with 14 grafting of limiting slot
Self-locking effect, the shape of kelly 3 are that T-shaped and kelly 3 material is steel material, and the quantity of kelly 3 is six, bull stick 4
Quantity be six and the material of bull stick 4 is steel material, the top of 3 inside of kelly is rotatably connected to bull stick 4, and bull stick 4 plays
The effect of transmission, the lower rotation in 4 outside of bull stick are connected with the switch block 5 with the rotation connection of the inner wall of handwheel 1, and switch block 5 plays biography
Dynamic effect, the shape of switch block 5 are the internal diameter that circular and switch block 5 internal diameter is not less than handwheel 1, and the material of switch block 5 is steel
The outer diameter of material and switch block 5 is not more than the outer diameter of handwheel 1.
The bottom of switch block 5 is fixedly connected with teeth piece 6, and the material of tooth block 6 is not less than for the internal diameter of steel material and tooth block 6 to be turned
The internal diameter of block 5, the outer diameter of torsional spring 7 are equal to the internal diameter of tooth block 6, and the inner wall of tooth block 6 is fixedly connected with and the fixed company of the inner wall of handwheel 1
The torsional spring 7 connect, the bottom of tooth block 6 are engaged with gear 8, and the middle part of gear 8, which is fixedly connected with, runs through and extend to 1 right side of handwheel
Pull ring 9, the left side of pull ring 9 are fixedly connected with ring gear 1, ring gear 1 engaged with ring gear 2 12 can limiting gear 8 rotate, tooth
The shape of ring 1 is that circular and ring gear 1 material is steel material, and spring 11 is compressive state, the shape of ring gear 2 12
Shape is annular shape, and the middle part in 9 left side of pull ring is fixedly connected with the spring 11 being fixedly connected with the inner wall of handwheel 1, and spring 11 plays
Ring gear 1 is engaged with ring gear 2 12 when pull ring 9 is pulled to left side simultaneously, and the effect that limitation pull ring 9 rotates, the inner wall of handwheel 1 is fixed
It is connected with ring gear 2 12 compatible with ring gear 1, the middle spiral of handwheel 1 is connected with screw rod 13, and the outside of screw rod 13 opens up
There is limiting slot 14 compatible with kelly 3.
Working principle: under original state, handwheel 1 is in self-locking state, and kelly 3 is stretched out from the middle part of handwheel 1 at this time, positioning
The state of bar 2, kelly 3 and bull stick 4 as shown in figure 4, and kelly 3 and 14 grafting of limiting slot, torsional spring 7 be in equilibrium state, drawing
Ring 9 moves to the left under the action of spring 11, but gear 8 is still engaged with tooth block 6, and ring gear 1 is engaged with ring gear 2 12 and led
It causes pull ring 9 that can not rotate, to guarantee that handwheel 1 can not rotate, is pulled to the right in self-locking state when needing to rotate handwheel 1
Pull ring 9, so pull ring 9 moves to the right with moving gear 8, makes ring gear 1 and ring gear since gear 8 is fixedly connected with pull ring 9
2 12 no longer engage, and are rotated further by pull ring 9 and rotate with moving gear 8, and gear 8 is rotated with movable tooth block 6, since tooth block 6 and switch block 5 are fixed
Connection, so switch block 5 also can rotate, switch block 5 drives bull stick 4 to rotate, and bull stick 4 drives kelly 3 to rotate, and makes kelly 3 around positioning
Bar 2 is rotated and is taken in handwheel 1, unlocks handwheel 1, can be rotated handwheel 1 at this moment to be adjusted.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
