There is no limit to creativity, and the instrument is invented. Today we introduce a national invention patent for authorization - a device dedicated to the detection of gas meter seals. The patent was filed by Haiyan Meijie Testing Instrument Co., Ltd. and was authorized to be announced on March 29, 2017.
Description
The utility model relates to a device dedicated to the sealing detection of a gas meter, which is dedicated to detecting the sealing performance of the gas meter.
Background of the invention
The gas meter leak detection device is used to detect whether there is a gas leakage problem in the gas meter, such as the Chinese patent with the patent number 200810059910 .1. The gas meter leakage detecting device of the prior art fixes the gas meter by means of up and down clamping at the time of detection. Due to the characteristics of the meter to be inspected (gas meter), the clamp is clamped by the seal ring in the middle. If the upper and lower clamp detection methods are used, the detection data in the middle of the checklist may be incorrect.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art, and to provide a device for detecting the sealing property of a gas meter with reasonable structure and accurate detection data.
The figure is a schematic view of the front view of the embodiment of the utility model
Compared with the prior art, the utility model has the following advantages and effects: a device dedicated to the gas meter sealing detection, including a gantry and a leak detecting mechanism detecting port; and a placing position on the gantry for placing the quilt Checking table; characterized in that it further comprises: lifting cylinder, clamping cylinder, clamping mechanism and lifting main frame; the cylinder of the lifting cylinder is mounted on the gantry, the lifting cylinder is vertically arranged, the piston is facing downward; the lifting main frame is fixed On the piston of the lifting cylinder; the clamping mechanism comprises an lifting bracket and a clamping head; the clamping head comprises an upper connecting piece, a lower connecting piece, a clamping piece, a hinge one, a hinge two and a hinge three; the upper connecting piece is hinged The lifting bracket is hinged and hinged to the lower connecting piece by the hinge 2; the lower connecting piece is hinged to the lifting main frame by the hinge 3; the clamping piece is fixed on the lower connecting piece; the hinge 2, the hinge 3, and the clamping piece are sequentially arranged from top to bottom; The detecting port of the leak detecting mechanism is installed on the lifting main frame; the detecting port of the leak detecting mechanism and the clamping mechanism are located above the placing position.
The lower connecting piece of the utility model comprises an upper joint, a sheet body and a lower joint; the upper joint is hinged to the lower end of the upper connecting piece by a hinge 2; the upper end of the sheet body is screwed and fixed to the upper joint, and the lower end is screwed with the clamping piece Fixed; one end of the lower joint is fixed to the sheet body, and the other end is hinged to the lifting main frame by a hinge three.
The two clamping heads of the utility model form a pair, and the two clamping heads are oppositely disposed; one clamping mechanism matches a checked table. Compared with the prior art, the utility model has the following advantages and effects: the structural design is reasonable; the efficiency is improved to reduce the manual labor; when the clamping mechanism is clamped, the clamped table is suspended, and the central part of the tested table is not subjected to force, so that the detection The data is accurate.
