[0002] Firefighting equipment refers to fixed facilities such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants in buildings. Engineering construction is a special accounting subject for construction and installation companies to collect and account for engineering costs. It is an activity of new construction, expansion, and reconstruction of construction projects based on the requirements of construction project design documents. During the construction process, corresponding temporary firefighting equipment must be set up on site, and firefighting pipes are pipes used to transmit firefighting water. Firefighting pipes must be able to withstand a certain water pressure.

The purpose of this arrangement is to connect the water guide hose to the flange of the fire-fighting pipe to be tested, and then the fire-fighting pipe can be filled through the electric pressure test pump body to test the water pressure of the pipe. When the electric pressure test pump body vibrates, the support pad can be pushed up through the buffer ring. Since the positioning pad limits the limit top plate and the support pad moves up, the two mounting collars can be pushed close to each other through the buffer connecting rod, thereby squeezing the buffer spring to contract. The deformation force of the buffer spring can buffer the impact force transmitted to the electric pressure test pump body through the buffer ring, so as to maintain the stability of the electric pressure test pump body.

[0006] Preferably, each of the buffer springs is sleeved on the outer side of the connecting cross bar.

[0012] (1) When the device is used, the water guide hose can be connected to the flange of the fire-fighting pipe to be tested, and then the fire-fighting pipe can be filled through the electric pressure test pump body to test the water pressure of the pipe. When the electric pressure test pump body vibrates, the support pad can be pushed up by the buffer ring. Since the positioning pad limits the limit top plate, and when the support pad moves up, the two mounting rings can be pushed close by the buffer connecting rod, thereby squeezing the buffer spring to contract. The deformation force of the buffer spring is used to buffer the impact force transmitted from the electric pressure test pump body through the buffer ring, so as to maintain the stability of the electric pressure test pump body.

[0013] (2) When it is necessary to remove a series of buffer structures to inspect the electric pressure test pump body, the positioning bolts can be removed to move the positioning pads upward, making it easier to move the limit top plate and the structure between the buffer ring upward and remove the electric pressure test pump body, so that the electric pressure test pump body can be directly inspected.
