Pressure-resistant air leakage detection device provided with limiting structure and used for plastic bottle

Abstract

The invention discloses a pressure-resistant air leakage detection device provided with a limiting structure and used for a plastic bottle. The pressure-resistant air leakage detection device comprises a base body, a water tank and a bracket fixing seat; a first sealing ring is arranged in the lower end of the base body; a first groove is formed in the base body; a first spring is arranged in thefirst groove; the first spring is connected with a first stop block; base body external threads are arranged at the upper end of the base body; and base body internal threads are arranged in the lowerend of the base body. According to the pressure-resistant air leakage detection device provided with the limiting structure and used for the plastic bottle, the bracket fixing seat, a first fixing bracket, a second fixing bracket and a friction pad are adopted, so that the device is convenient to fix and limit the plastic bottle. The working principle of the device is as follows: the outer side of the plastic bottle is attached to the friction pad on the inner side of the first fixing bracket; and the inserting rod of the second fixing bracket is inserted into an inserting hole in the first fixing bracket until the inserting rod is clamped with a second stop block, so that fixing and limiting of the plastic bottle can be completed, great convenience is achieved, and practicability is improved.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a pressure-resistant air leakage detection device for plastic bottles with a position-limiting structure. Background technique [0002] Plastic bottles use polyester (PET), polyethylene (PE) and polypropylene (PP) as raw materials, after adding corresponding organic solvents, after high temperature heating, blow molding, extrusion blowing, or injection molding through plastic molds Plastic containers, plastic bottles have the characteristics of unbreakable, low cost, high transparency, and food-grade raw materials. Plastic bottles need to be tested for air tightness during production, which requires the use of air leakage detection devices, but currently There are still many deficiencies in the air leakage detection device for plastic bottles, such as: [0003] 1. At present, the air leakage detection device for plastic bottles on the market is not easy to detect. Due ...
