[0002] Fluid is a form of object corresponding to solid. It is a general term for liquids and gases. It is composed of a large number of molecules that are constantly in thermal motion and have no fixed equilibrium position. Its basic characteristics are that it has no definite shape and has fluidity. Pumps are often used in fluid transportation, but when the pump is adjusted, the pressure in the pipeline used to transport the fluid will change, which can easily cause the connection between the pump and the pipeline to burst.

[0003] A Chinese patent discloses a fluid pump with the publication number CN210919430U. The article states that "a driving rotor, a driven rotor meshing with the driving rotor, and a rotor drive shaft driving the driving rotor are installed in the fluid pump; the driving rotor has an axial hole for inserting the rotor drive shaft, the inner wall of the axial hole is provided with internal teeth, the rotor drive shaft is provided with external teeth meshing with the internal teeth of the inner wall of the axial hole, and the rotation center of the rotor drive shaft is eccentrically arranged relative to the rotation center of the driving rotor." However, the prior art does not have an explosion-proof function, and cannot buffer the connection between the pump and the fluid delivery pipeline when the fluid pump is adjusted, and the connection between the pump and the pipeline is prone to explosion. Therefore, it is very necessary to design a connector for fluid equipment with an explosion-proof function. Utility Model Content

[0008] Preferably, the number of support plates in each group is equal, and two adjacent support plates are connected by a rotating shaft. The support plates are arc-shaped and are evenly distributed outside the corrugated flow guide tube in a circular array.

[0009] Preferably, brackets are welded to both side outer walls of the connector body, and an oblique support rod is inserted into the bottom of the bracket, and a support block is provided at one end of the bottom of the oblique support rod.

[0010] Preferably, a plurality of insertion holes are equidistantly formed on the diagonal support rod, an insertion rod is inserted into the bracket, and one end of the insertion rod extends into the insertion hole.

[0014] Beneficial effects of the utility model:

[0015] 1. The fluid can be transported to the corrugated guide tube through the connecting hose. When the fluid flow rate increases instantly, the fluid will stretch the corrugated guide tube to release the pressure and avoid the pressure acting on the connection between the pump body and the connector body. The support plate can fit the corrugated guide tube from all angles. When the corrugated guide tube bulges, the support plate and spring rod can play a buffering effect, which is beneficial to improve the explosion-proof performance and avoid the explosion at the connection between the pump and the pipeline.

[0016] 2. The sealing gasket can be used to increase the tightness of the connection between the connecting ring and the connecting hose. The lifting block can be lifted to move the insertion rod out of the socket, and the diagonal support rod can be pulled out. The connector body can be supported by the diagonal support rod and the support block, which is beneficial to improve the stability of the connector body. Loosen the lifting block, and under the action of the reset spring, the insertion rod can be pushed into the socket, thereby fixing the length of the diagonal support rod. The sealing ring can be used to increase the connectivity between the pump body and the connector body, which is beneficial to improve the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS
