[New patent introduction] A smart digital pressure gauge

Today, I will introduce a national invention authorized patent-a smart digital pressure gauge. The patent was applied for by Wuxi Kaifeng Pressure Gauge Co., Ltd., and the authorization was announced on December 22, 2017.

Content description

The invention relates to the technical field of pressure gauges, in particular to an intelligent digital pressure gauge.

Background of the invention

Intelligent digital pressure gauges are widely used in petroleum, chemical fiber, plastics, rubber and other industries to measure and control pressure. Generally, they have upper and lower pressure alarms, which can be output by relay contacts, voltage pulses, and triac-driven triggers. ; Two-channel constant current output and other functions. Working pressure is one of the most important parameters in the hydraulic system. In order to detect the pressure, a pressure gauge is required. However, the existing pressure gauge cannot effectively monitor the display during use. For protection, it is easy to cause damage to the display screen, thereby affecting people's normal use.

Summary of the invention

The purpose of the present invention is to provide an intelligent digital pressure gauge, which has the advantages of being able to effectively protect the display screen without being easily damaged, and solves the problem that the display screen cannot be effectively protected and is prone to damage.

In order to achieve the above objective, the present invention provides the following technical solutions: an intelligent digital pressure gauge, including a body, the front of the body is provided with a display screen, the front of the body is provided with buttons at the bottom of the display screen, and the top and bottom of the left side of the body The cover plate is hinged by a hinge; the first card slot is opened at the axis on the right side of the front of the body, and the first card block used in conjunction with the first card slot is fixedly connected to the axis on the left side of the front of the cover plate. A first through hole is opened on the left side of the front of the block, a second slot is opened on the right side of the first block, and the second slot is connected to the first through hole, and a first hole is opened on the axis on the right side of the body. A long hole, and the first long hole communicates with the first card slot, the inside of the first through hole is provided with a connecting rod, the right side of the connecting rod extends to the outside of the body is fixedly connected with a fixing block, the surface of the body is located on the first card A second elongated hole is opened on the left side of the slot, and the second elongated hole is connected with the first slot. The left side of the inner cavity of the second elongated hole is fixedly connected with a first spring, and the end of the first spring is far away from the inner wall of the second elongated hole A second clamping block used in cooperation with the second clamping slot is fixedly connected, and one end of the second clamping block away from the first spring extends to the inside of the first clamping slot.

The top and bottom of the connecting rod are fixedly connected to the right side of the sliding block. The surface of the body and located at the top and bottom of the first long hole are provided with sliding grooves for use with the sliding block, and the sliding groove is connected with the first long hole. The sliding block is slidably connected with the sliding groove. A second spring is fixedly connected to the left side of the sliding block, and one end of the second spring away from the sliding block is fixedly connected to the inner wall of the sliding groove. The bottom of the machine body is fixedly connected with a connecting block, and the bottom of the connecting block is fixedly connected with a threaded rod. The front of the cover plate is provided with a second through hole used in cooperation with the display screen, and a glass plate is arranged inside the second through hole.

Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention achieves the effect of pressure detection by arranging the body and the display screen, and achieves the effect of protecting the display screen and the body through the cover plate. Block and the first card slot, to achieve the effect of fixing the cover, through the second card block and the second card slot, to achieve the effect of fixing the first card block, through the connecting rod, press to drive the second card block to move , It can effectively protect the display screen, is not easy to appear damaged, and is convenient for people to use. 2. The present invention facilitates the movement of the connecting rod through the first through hole, and at the same time, it is convenient for the cover plate to drive the first block to be drawn out from the first card slot, and through the second through hole and the glass plate, it is convenient for pressure on the display To watch, it also achieves the effect of protecting the display screen. Through the fixed block, it is convenient for the user to press the connecting rod to prevent the connecting rod from being unable to move. Through the connecting block and the threaded rod, the effect of fixing the body is achieved and avoiding the appearance For undetectable conditions, through the slider and the sliding groove, the effect of assisting the movement of the connecting rod is achieved, avoiding the situation that the connecting rod cannot be reset after the movement, and the second spring achieves the effect of supporting the slider.
