Abstract
The utility model provides a joint pin used for dead holes, comprising a joint pin body. An inside threaded hole is arranged on a central shaft at the joint ends of the joint pin and the dead hole, a through hole is arranged on a central shaft back to the inside threaded hole and is communicated with the inside threaded hole. A ventilation pipe is arranged in the joint pin to prevent air pressure production and to facilitate installation; in addition, the inside threaded hole arranged at the joint ends of the joint pin and the dead hole to facilitate the joint pin to be screwed out through a screw. The utility model is characterized by simple structure and convenient operation.
Description
Technical field:
The utility model relates to a kind of blind hole attachment pegs.
Background technique:
Existing blind hole attachment pegs is solid pin, two defectives of this kind attachment pegs existence, and the one, in the blind hole connection procedure,, produce air pressure owing to the gas that can't get rid of in the blind hole, make difficulty is installed, the 2nd, work as attachment pegs and fracture in blind hole, it is big to dismantle difficulty.
Summary of the invention:
The purpose of this utility model just provides a kind of easy for installation, and dismounting is easy to the blind hole attachment pegs.
The purpose of this utility model can realize by following scheme, comprises the connection shank, is provided with interior threaded hole on the end central shaft that the connection shank connects with blind hole, is provided with through hole on the central shaft of the back of interior threaded hole, and described interior threaded hole is communicated with through hole.
The diameter of described through hole is greater than the diameter of interior threaded hole.
Because the attachment pegs the inside is provided with breather line, has avoided the air pressure generation, and is easy for installation, again because an end that connects with blind hole at the connection shank is provided with interior threaded hole, be convenient to attachment pegs be back-outed in addition by the jackscrew screw rod.
The utlity model has characteristics such as simple in structure, easy to use.
