[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Reference Figure 1-2 A pressure reducing filter air tightness test fixture comprises a base 1, a mounting frame 1 2 and a mounting frame 2 3 arranged on the base 1, a positioning component 4 arranged on the mounting frame 1 2 for placing a pressure reducing filter 5, a pressing component 6 arranged on the mounting frame 2 3 for fixing the pressure reducing filter 5 on the positioning component 4, and an air intake component 7 for inflating air into the pressure reducing filter 5.

[0017] The utility model fixes the pressure reducing filter 5 by the cooperation of the positioning component 4 and the pressing component 6, and inflates the pressure reducing filter 5 through the air inlet component 7 to observe the pressure gauge (not shown) on the pressure reducing filter 5, so as to complete the process of detecting the air tightness of the pressure reducing filter 5, with simple operation and high detection efficiency.

[0018] In an optional embodiment of the present invention, the positioning assembly 4 includes a plug connector 401 and a bolt 402 connecting the plug connector 401 and the mounting frame 2. Preliminary positioning is performed by inserting one side of the pressure reducing filter 5 into the plug connector 401, so that the clamping assembly 6 is aligned with the other side of the pressure reducing filter 5 for clamping and fixing.

[0019] In an optional embodiment of the present invention, the clamping assembly 6 includes a clamping part 601, a power part 602 for driving the clamping part 601 to clamp the pressure reducing filter 5, and a control part 603 for controlling the action of the power part 602. The control part 603 controls the power part 602 to push the clamping part 601 toward the pressure reducing filter 5, and clamps and fixes the pressure reducing filter 5, so as to facilitate the air tightness detection of the pressure reducing filter 5.

[0020] In an optional embodiment of the present invention, the clamping portion 601 includes a plug connector 60101 for inserting the pressure reducing filter 5, and a bolt 60102 fixed to one end of the plug connector 60101. The bolt 60102 and the bolt 1 402 cooperate to clamp the pressure reducing filter 5 and simultaneously drive the plug connector 60101 to be inserted into the pressure reducing filter 5.

[0021] In an optional embodiment of the present invention, the power unit 602 is a cylinder, and the plug connector 2 60101 is driven to enter and exit the pressure reducing filter 5 through the extension and contraction action of the cylinder.

[0022] In an optional embodiment of the present invention, the control unit 603 is a pneumatic switch. The pneumatic switch in this embodiment is connected to the cylinder through a hose (not shown). The movement of the cylinder is controlled by toggling the pneumatic switch, thereby controlling the plug connector 60101 to enter and exit the pressure reducing filter 5.

[0023] In an optional embodiment of the utility model, the air intake assembly 7 includes an air intake channel 701 opened in the plug connector 60101 and an air intake pipe 702 connected to the air intake channel 701. Preferably, the air intake pipe 702 in this embodiment is connected to an external air source. After the plug connector 60101 is inserted into the pressure reducing filter 5, the air intake pipe 702 is used to inflate the pressure reducing filter 5. Workers can judge the air tightness of the pressure reducing filter 5 by observing the pressure gauge on the pressure reducing filter 5. The operation is simple and the detection efficiency is high.

[0024] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
