[0006] To achieve the above purpose, the utility model adopts the technical scheme of:

[0007] A detection device of explosion -proof test product, which comprises a protective shell, a protective cover, a clamping assembly and a detection assembly, wherein the protective cover is rotatably connected to the protective shell and surrounded in the protective shell to form a detection cavity.

[0008] The clamping assembly comprises a cylinder, a pushing plate and a bearing plate, the cylinder is arranged on the top of the protective cover, the output end of the cylinder penetrates the protective cover and is connected with the pushing plate in the detection cavity, the pushing plate is provided with a limiting rod, and the limiting rod is matched with the limiting hole on the protective cover; the bearing plate is arranged on the bottom of the detection cavity, the bottom of the bearing plate is provided with a plurality of springs, the bearing plate is in abutting connection with the bottom of the detection cavity through the springs, the bearing plate is provided with a tube positive rod, and the tube positive rod is matched with the tube positive hole on the bottom of the protective shell;

[0009] The detection assembly comprises a gas pump, a hose, a gas nozzle and a positioning member, the gas pump is arranged on the outer side wall of the protective shell, one end of the hose is connected with the gas pump, the other end is communicated with the gas nozzle, the upper end face of the gas nozzle is provided with a first magnet, and the gas nozzle is adsorbed on the pushing plate through the first magnet; the positioning member comprises a positioning piece and a limiting piece, the positioning piece is in U-shaped structure, the bottom of the positioning piece is provided with a second magnet, and the positioning piece is adsorbed on the bearing plate through the second magnet; the limiting piece is movably connected in the U-shaped structure of the positioning piece, the bottom of the limiting piece is provided with a third magnet, and the limiting piece is adsorbed on the bearing plate through the third magnet; the limiting piece is provided with a movable rod, and the movable rod is matched with the movable hole on the positioning piece.

[0010] The detection device of the explosion-proof test product with the structure, the detection cavity surrounded by the protective cover and the protective shell is used for placing the detected piece and carrying out explosion-proof test, so first of all, the component capable of pumping gas for detection is needed, therefore, the gas pump is arranged outside the protective shell, the hose communicated with the gas pump is connected with the gas nozzle after penetrating the protective shell, the gas nozzle is sleeved on the gas inlet of the detected piece, in order to pump gas, the gas nozzle on the gas inlet of the detected piece needs to be pressed, so as to avoid gas leakage, therefore, the clamping assembly needs to be additionally arranged, therefore, the bearing plate is arranged on the bottom of the detection cavity for placing the detected piece, the cylinder is arranged on the top of the protective cover for pushing the pushing plate in the detection cavity, in order to ensure that the pushing plate moves vertically downward without deviation, therefore, the limiting rod is arranged on the pushing plate, and the limiting rod is matched with the limiting hole on the protective cover, so that the pushing plate can keep vertical downward during movement. After the detected piece is placed on the bearing plate, the gas nozzle is sleeved on the gas inlet, the protective cover is closed, the cylinder is started to push the pushing plate downward, so that the pushing plate abuts on the gas nozzle and keeps downward pressing force, and the gas is pumped during the starting of the gas pump to detect the explosion-proof performance of the detected piece.

[0011] But the structure can only detect a group of to-be-detected pieces, and each group needs to be placed after the air nozzle is pressed, and it cannot be detected quickly, so a first magnet is arranged on the upper end face of the air nozzle, so that the air nozzle can be adsorbed on the push plate, and in addition, a positioning member is additionally arranged, and the U-shaped positioning piece is adsorbed on the bearing plate through the second magnet at the bottom of the positioning piece, so that before detecting the to-be-detected piece, the positioning piece is placed at any position on the bearing plate, and the bottom of the to-be-detected piece is abutted on the positioning piece, and then the air nozzle is sleeved on the air inlet, the protective cover is closed, and the push plate is pressed down, when the push plate contacts the first magnet, the air nozzle is adsorbed on the push plate, and the to-be-detected piece is taken out after the protective cover is opened, so that in the subsequent detection, the to-be-detected piece only needs to be placed and abutted on the positioning piece at the position of the last detection, so that the air nozzle can be kept at the last pressing position when the push plate is pressed down, so that the positioning of each time can be accurate, and the specific position of the first detection can also be defined, and the positioning piece can be placed at will.

[0012] But because the sizes of the bottoms of different types of to-be-detected pieces are different, the positioning piece cannot be suitable for all types of to-be-detected pieces, so a limiting piece is movably connected on the positioning piece, and the limiting piece is matched with the movable hole on the positioning piece through the movable rod, so that the limiting piece can be flexibly adjusted in the transverse direction, and a third magnet is additionally arranged at the bottom of the limiting piece, so that after the position adjustment of the limiting piece is completed, a single type of to-be-detected piece can be matched, and when other to-be-detected pieces need to be detected, the limiting piece needs to be adjusted, so that more different types of to-be-detected pieces can be matched.
