Description

Technical Field

[0001] The utility model relates to the technical field of fluid detection, and particularly relates to a fluid detection device. Background Art

[0002] In the prior art, there are devices to be detected with multiple channels, such as a pressure sensor box. Since there are several different independent channels inside the pressure sensor box, it is necessary to perform fluid detection on multiple channels under different working environments at the finished product stage.

[0003] The prior art usually directly connects a single channel of the pressure sensor box to a pressure control device, and then places the pressure sensor box in a high and low temperature environment for testing. As a result, only one channel of a single product can be tested each time, and integrated testing cannot be performed, resulting in low detection efficiency. Summary of the Utility Model

[0004] Aiming at the above problems in the prior art, the utility model provides a fluid detection device, which solves the problem of low fluid detection efficiency of the device to be detected in the prior art.

[0006] A fluid detection device is provided, including a first fixing plate and a second fixing plate which are relatively fixedly arranged. At least two air vent pipes are arranged on two adjacent surfaces of the first fixing plate and the second fixing plate. An air inlet for communicating with an external fluid is arranged at one end of each air vent pipe, and at least two air outlet ports which are all communicated with the air inlet are arranged on the outer wall of each air vent pipe. A connecting piece for quick plug connection with an external device to be detected is arranged at each air outlet port.

[0007] This scheme can at least perform fluid detection on multiple channels in two devices to be detected. For example, fluid detection is performed on two pressure sensor boxes. Since air vent pipes are arranged on both the first fixing plate and the second fixing plate, and each air vent pipe can be quickly plugged and connected to multiple channels on the pressure sensor box through multiple connecting pieces, after the fluid with a certain air pressure is introduced into the multiple air vent pipes located on the first fixing plate and the second fixing plate, fluid detection can be at least respectively performed on multiple channels in two pressure sensor boxes, completing integrated testing and improving the detection efficiency.

[0008] Furthermore, both the first fixing plate and the second fixing plate are rectangular plate structures, and the first fixing plate and the second fixing plate are connected by multiple connecting rods through screw threads. The screw connection of the connecting rods facilitates installation and disassembly.

[0009] Further, a plurality of bumps are provided on both side surfaces of the first fixing plate and the second fixing plate, and a connection hole is provided on each bump. One end of each connecting rod passes through the first fixing plate and the second fixing plate in sequence through the connection hole and is threadedly connected with a wing nut.

[0010] Further, at least two mounting grooves for fixing the ventilation pipe are provided on two adjacent surfaces of the first fixing plate and the second fixing plate. The arrangement of the mounting grooves facilitates the positioning of the ventilation pipe.

[0011] Further, each ventilation pipe is a rectangular column structure with a flow channel provided therein. The cross-section of each mounting groove is rectangular, and each ventilation pipe is embedded in the corresponding mounting groove. The ventilation pipe with a rectangular cross-section is convenient to be embedded in the mounting groove.

[0012] Further, the number of mounting grooves on the second fixing plate is greater than the number of mounting grooves on the first fixing plate.

[0013] Further, an air inlet nozzle is provided at the air inlet on one end of each ventilation pipe, and a plug is provided in the opening at the other end of each ventilation pipe. The arrangement of the air inlet nozzle facilitates the connection with an external pressure device, and facilitates the introduction of a fluid with a certain air pressure into the ventilation pipe to detect the pressure sensor box.

[0014] Further, each air inlet nozzle has a stepped circular structure. The large diameter end of the air inlet nozzle is conical, and the small diameter end of the air inlet nozzle is threadedly connected to the air inlet on the corresponding ventilation pipe.

[0015] Further, the connecting member is a quick-connect adapter. A sealing ring is provided at the connection between the top of the quick-connect adapter and the external device to be detected. The arrangement of the sealing ring improves the sealing performance.

[0016] Further, the quick-connect adapter includes a transfer portion and a connection portion that are interconnected. The transfer portion is used for connection with the external device to be detected, and the connection portion is used for connection with the air outlet on the ventilation pipe. An annular groove is provided on the outer wall of the connection portion, and an O-ring is provided on the annular groove.

[0017] The present utility model discloses a fluid detection device, and its beneficial effects are as follows:

[0018] In the present utility model, since ventilation pipes are provided on both the first fixing plate and the second fixing plate, and each ventilation pipe can be quickly plugged and connected to a plurality of passages on the pressure sensor box through a plurality of connecting members, after the plurality of ventilation pipes on the first fixing plate and the second fixing plate are connected to a fluid with a certain external air pressure, they can at least respectively perform fluid detection on a plurality of passages in two pressure sensor boxes, perform integrated detection on the device to be detected, and improve the detection efficiency.
