Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Fig. 1 shows a handle mechanism with a self-locking device for a valve according to an embodiment of the present invention. The handle comprises an operating handle rod 1 and a mounting part 2 arranged at the end part of the operating handle rod 1, wherein a clamping groove is arranged on one side surface of the mounting part 2, the clamping groove comprises two oppositely arranged bosses 21, a strip-shaped gap 22 is arranged between the two bosses, and grooves 23 which are perpendicular to the strip-shaped gap 22 and are symmetrical along the strip-shaped gap 22 are formed in the end surfaces of the two bosses 21; a first locking hole 24 penetrating through the mounting component body is arranged between the two grooves 23.
The self-locking assembly comprises a rotating head 3 and a locking shaft 4, the rotating head 3 comprises a rotating head body 31, two bulges 32 are arranged on one end face of the rotating head body 31, and a second locking hole 33 penetrating through the rotating head body is formed in the center of the end face; the locking shaft 4 is located in the first locking hole 24 and the second locking hole 33.
The width of the strip-shaped gap 22 is the same as that of the groove 23, and is matched with the width of the two protrusions 32.
The rotator body 31 is provided with a first pin hole 33 perpendicular to the second locking hole 32, the locking shaft 4 is provided with a second pin hole 41 in the radial direction, and the rotator further comprises a fixing pin (the fixing pin is a conventional component in the technical field and is not shown in the figure), and the fixing pin passes through the first pin hole 34 and the second pin hole 41 to fasten the rotator body 31 and the locking shaft 4.
In a preferred embodiment, the first locking hole 24 is a stepped hole, and a section near the clamping groove is a small hole 241, and the other section is a large hole 242; also comprises a return spring 5; the locking shaft 4 sequentially penetrates through a large hole 242, a small hole 241 and a second locking hole 33 of the first locking hole, the shape of the locking shaft 4 is matched with the stepped hole, the locking shaft 4 which is larger and is positioned in the large hole is called as a large end, the locking shaft 4 is further sleeved with a return spring 5, the return spring is positioned in the large hole, one end of the return spring is abutted to the large end of the locking shaft 4, and the other end of the return spring is abutted to the wall of the large hole 242.
Only one end of the locking shaft 4 is a big end, so that the volume of the self-locking assembly 3 can be reduced. In addition, after the return spring 5 is additionally arranged, the large end of the locking shaft 4 is pressed by the return spring 5, and the locking shaft is connected with the valve body more firmly. When the protrusion 32 is engaged in the engaging groove 23, the pulling force generated by the return spring 5 can also make the rotating head 3 more firmly engaged in the engaging groove 23.
