Description

Technical Field

[0002] A pressure gauge is an instrument for measuring fluid pressure, and a U-type pressure gauge is a type of pressure gauge. The operating principle of a U-type pressure gauge is: when the U-type pressure gauge is not connected to the pressure measuring point, the liquid levels on both sides of the U-shaped glass tube are level at the zero scale line. When one end of the U-shaped tube is connected to the pressure measuring point, the liquid level in the U-shaped tube will change. If the liquid level on the side connected to the pressure measuring point drops, it means that the pressure at the pressure measuring point is positive pressure, otherwise it is negative pressure.

[0022] In this embodiment, when the U-shaped pressure gauge body 6 or the LED light board 11 is damaged, the pull ring 33 is pulled outward, and the pull ring 33 will drive the fixing pin 32 to move horizontally. At this time, the fixing pin 32 will be separated from the protective shell 2, and the fixing pin 32 will drive the movable block 34 to squeeze the movable spring 35, and then the connecting head 8 is rotated to separate it from the U-shaped pressure gauge body 6, and the protective shell 2 is lifted up to separate it from the base 1, so that it is convenient to repair the U-shaped pressure gauge body 6 or the LED light board 11 arranged inside the protective shell 2.

[0023] See also Figure 1 and Figure 2 A mounting plate 5 is provided inside the protective shell 2, the bottom of the mounting plate 5 is fixedly connected to the top of the base 1, a U-shaped pressure gauge body 6 is fixedly installed on the front of the mounting plate 5, a scale pattern 7 is provided in the middle of the front of the mounting plate 5, a connector 8 is sleeved on the external thread of the top of the U-shaped pressure gauge body 6, and the top of the U-shaped pressure gauge body 6 penetrates and extends to the top of the protective shell 2;

[0026] In this embodiment, when the charging interface 43 is used to connect the external circuit, the electric energy in the external circuit can be transmitted along the charging line 42 to the inside of the battery 41, thereby facilitating the storage of the electric energy. If the switch 10 is pressed to connect the circuit of the wire 9, the electric energy inside the battery 41 can be transmitted to the inside of the LED light board 11, causing the LED light board 11 to generate light due to power on.
