Detailed Description
The utility model will be described in detail below with respect to certain specific embodiments thereof in order to better understand the utility model and thereby to more clearly define the scope of the utility model as claimed. It should be noted that the following description is only some embodiments of the inventive concept and is only a part of examples of the present utility model, wherein the specific direct description of the related structures is only for the convenience of understanding the present utility model, and the specific features do not naturally and directly limit the implementation scope of the present utility model.
Referring to the drawings, the utility model adopts the following technical scheme that the positioning plate of the perforating gun comprises a positioning plate main body 1, wherein a through hole 2 is formed in the positioning plate main body 1;
a first accommodating hole 3 is formed in one side of the positioning disc main body 1, the positioning disc main body further comprises a first screw hole 4 which is communicated with the first accommodating hole 3 at an included angle, steel balls 5 are placed in the first accommodating hole 3, and a screw 7 is connected in the first screw hole 4 in a threaded manner so that the steel balls 5 move outwards to be matched with a bullet rack of the perforating gun;
At least one positioning screw hole 6 is radially formed in the positioning disc main body 1.
Through the technical scheme, the utility model is fixedly installed in the existing positioning disk installation mode, namely, the positioning screw 7 is used for preliminary installation and fixation, and then the screw 7 is connected in a threaded manner, so that the steel balls 5 are radially pushed outwards, and the steel balls are propped against the spring frame, so that stable positioning is realized.
As one preferable aspect, the first accommodating hole 3 is formed on the circumferential side of the puck body 1.
