Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The embodiment is that a handle of a hemispherical angle cock, as shown in figures 1 and 2, comprises an angle cock body 1, a valve core block 2 rotationally inserted with the angle cock body 1 and a handle block 3 rotationally inserted with the valve core block 2, and the toggle control of the valve core block 2 on the angle cock body 1 can be realized by the operation of the handle block 3.
The handle piece 3 includes handle rotation portion 4 and handle grip portion 5, and operating personnel holds handle grip portion 5 drive handle rotation portion 4 and rotates the regulation, and handle rotation portion 4 is equipped with installation change groove 6, can follow the lift of handle and loosen the activity that the process realized with case piece 2 top and cup joint, and installation change groove 6 is kept away from handle grip portion 5 one side be equipped with case piece 2 rotate the rotation connecting groove piece 7 of being connected, thereby has ensured the rotation of handle piece 3 for case piece 2 and has twistd reverse the regulation.
One side of the installation rotary groove 6, which is far away from the rotary connecting groove block 7, is provided with a rotary clamping block 8, the bevel door body 1 is provided with a rotary stop block 9 matched with the rotary clamping block 8, and the rotary stop block 9 can be matched with the rotary clamping block 8, so that the stability of the handle block 3 in a locking and closing state is improved.
As shown in fig. 1, 3 and 4, in order to further improve the locking stability of the handle block 3, a pair of movable locking blocks 10 are slidably connected to two sides of the rotating block 8, so as to improve the mating and abutting strength between the rotating block 8 and the rotating stop block 9. The locking fixture block 10 is provided with a mounting sliding groove 11, the rotating fixture block 8 is provided with a mounting sliding block 12 which is in sliding connection with the mounting sliding groove 11, the rotating sliding path of the locking fixture block 10 relative to the rotating fixture block 8 is limited, and the sliding displacement deviation is reduced. The locking fixture block 10 is further provided with a reset chute block 13, the rotating fixture block 8 is provided with a sliding lug block 14 which is matched with the reset chute block 13 in a sliding manner, a reset pressure spring 15 is arranged between the sliding lug block 14 and the chute wall of the reset chute block 13 in a penetrating manner, the sliding of the sliding lug block 14 relative to the reset chute block 13 is realized by means of elastic expansion and contraction of the reset pressure spring 15, and the sliding lug block 14 and the reset chute block 13 are respectively provided with a tight supporting lug 22 for clamping and embedding the end part of the reset pressure spring 15, so that the deformation reliability of the expansion and contraction process of the reset pressure spring 15 is improved. Finally, when an operator presses the handle block 3, the locking clamping block 10 is extruded relative to the rotation stopping block 9, so that the locking clamping block 10 is driven to slide relative to the rotation clamping block 8 by pressing and the reset pressure spring 15 is compressed, the tight abutting between the locking clamping block 10 and the rotation stopping block 9 is maintained, and the stability of the locking state of the handle block 3 is ensured.
In order to further improve the matching reliability between the locking clamping block 10 and the rotating clamping block 8, one end, in contact with the rotating stop block 9, of the locking clamping block 10 is provided with a locking flange 17, and an auxiliary pressing groove 18 for the embedding and the inserting of the rotating clamping block 8 is arranged on the locking flange 17, namely, when the handle block 3 is pressed by an operator to complete the locking with the folding angle cock body 1, the auxiliary pressing groove 18 is clamped with the rotating clamping block 8, so that the limiting sliding and the matching locking effect between the rotating clamping block 8 and the locking clamping block 10 are improved. Considering that the contact movement smoothness of the locking clamping block 10 and the rotation stop block 9 is realized in the process of pressing and buckling the handle block 3, the rotation stop block 9 is provided with a guide bevel edge 19, the relative sliding of the guide bevel edge 19 and the locking clamping block 10 is used for helping to realize limit guiding on the pressing movement of the handle block 3, and the gentle process of relative extrusion between the locking clamping block 10 and the rotation stop block 9 to a propping state is ensured. The friction rib blocks 23 are arranged at the end parts of the locking clamping blocks 10, so that the degree of abutting and locking sufficiency between the locking clamping blocks 10 and the rotation stop block 9 is further improved, and the free opening state of the handle block 3 is reduced.
