Description

Technical Field

[0001] This utility model relates to a sampling inspection device, and in particular to a dummy load coolant injection device. Background Technology

[0002] A dummy load coolant is a device used in laboratories or industrial production that uses a liquid circulation system to transfer heat from electronic components or equipment to achieve cooling. The working principle of a liquid-cooled dummy load is to use a water pump to draw coolant (usually water or other liquid) from the water tank, then pump the coolant into the radiator, dissipate heat through the radiator, and then return to the water tank for circulation.

[0003] The water pump has two connecting pipes. However, when the connecting pipes are not connected to external pipes, they are exposed, making it easy for foreign objects to enter the pump body through the pipes, which will affect the operation of the water pump. Utility Model Content

[0004] The main objective of this invention is to provide a dummy load coolant injection device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dummy load coolant injection device includes a motor, a pump body, a protective kit, and a limiting protective cover. The pump body is fixedly installed at the front end of the motor. The protective kit is movably fitted on the surface of the pump body. The limiting protective cover is movably embedded inside the front end of the protective kit. Mounting brackets are fixedly installed on the rear surface of the front end of the motor and on both sides below. A support block is fixedly installed on the lower surface of the rear end of the motor.

[0007] More preferably, a first connecting pipe is fixedly installed on the front surface of the injection pump body, a second connecting pipe is fixedly installed on the upper surface of the injection pump body, and an annular groove is formed on the surface of the injection pump body behind the second connecting pipe.

[0008] More preferably, the protective kit includes an L-shaped baffle, a storage sleeve, a knob, a threaded rod, and a collar. The knob is movably mounted on the upper front surface of the L-shaped baffle, the threaded rod is fixedly mounted on the lower surface of the knob, the storage sleeve is fixedly mounted on the lower front surface of the L-shaped baffle, and a collar is fixedly mounted on the lower rear surface of the L-shaped baffle.

[0009] More preferably, the collar is movably fitted in the annular groove, the protective kit is movably connected to the injection pump body through the collar, the rear surface of the receiving sleeve is provided with a groove, and the inner two sides of the groove are longitudinally provided with sliding grooves.

[0010] More preferably, the rear surface of the limiting protective cover is provided with a sleeve groove, the upper two sides of the limiting protective cover are fixedly installed with sliders, and the upper surface of the limiting protective cover is provided with threaded holes.

[0011] More preferably, the limiting protective cover is embedded in the groove, and the slider is embedded in the slide groove.

[0012] More preferably, the lower end of the threaded rod extends into the groove and is embedded in the threaded hole.

[0013] Compared with the prior art, this utility model proposes a dummy load coolant injection device, which has the following beneficial effects:

[0014] In this invention, by setting up a pump body, a protective kit, and a limiting protective cover in a coordinated manner, when the first and second connecting pipes of the pump body are disconnected from the external pipeline, the protective kit is rotated so that the L-shaped baffle of the protective kit covers the second connecting pipe. Then, the knob of the protective kit is rotated, and the knob drives the threaded rod to rotate. The rotating threaded rod causes the limiting protective cover to extend out of the groove until the limiting protective cover covers the first connecting rod. In this way, the first and second connecting pipes can be protected after disconnection, preventing foreign objects from entering the pump body. Attached Figure Description
