Embodiment Construction

[0015] refer to figure 1 As shown in FIG. 3, a simple pressure gauge is mainly composed of a base 1, a watch case 2, a Barton tube 3, a pointer 4, an indicating panel 5 and a transparent mask 6, and the watch case 2 is arranged on the outer peripheral edge of the upper surface of the base 1. The above-mentioned base 1 and watch case 2 can be two parts that are processed independently of each other, or can be a part that is integrally formed and processed. Here, as a preferred processing method, the base 1 and the watch case 2 are obtained by injection molding and integral molding; The inner cavity enclosed by the watch case 2 and the base 1 is provided with a fluid input portion 10 that can communicate with the fluid. The fluid input portion 10 is fixedly installed on the base 1 , and the fluid input portion 10 is in contact with one end of the Barton tube 3 . Connection, the other end of the Barton tube 3 is connected with a link rod 30, the other end of the link rod 30 is co...

Abstract

The invention discloses a simple pressure gauge which is mainly composed of a base, a gauge case, a Barton tube, a pointer, an indication panel and a transparent cover. The gauge case is arranged at the edge of the periphery of the upper surface of the base, a fluid inputting portion which can be communicated with fluid is arranged inside an inner cavity defined by the gauge case and the base, the fluid inputting portion is fixedly installed on the base, the fluid inputting portion is connected with one end of the Barton tube, the other end of the Barton tube is connected with a linkage rod, the other end of the linkage rod is connected with a rotary disk, a rotary shaft is arranged in the center of the rotary disk, the rotary shaft is installed on the upper surface of the base and located on one side of the fluid inputting portion, and the upper portion of the rotary shaft is fixedly connected with the pointer. The linkage rod and the rotary disk are used in a matching mode, so that a movement with a complex structure is replaced, and therefore production and installation of the pressure gauge are simpler and faster, improvement of the production efficiency of the pressure gauge is facilitated, and the social competitive power of an enterprise is enhanced.

Description

technical field [0001] The invention relates to a pressure gauge, which belongs to the technical field of measurement and control instruments. Background technique [0002] As is well known, pressure gauges are widely used in industry for measuring the pressure of fluids such as gases or liquids. The current pressure gauge is generally composed of a base, a watch case, a Barton tube, a pointer, an indicating panel, a movement and a transparent mask. The watch case is arranged at the outer peripheral edge of the upper surface of the base. The inner cavity is provided with a fluid input part that can communicate with the fluid, the fluid input part is fixedly installed on the base, the fluid input part is connected with one end of the Barton tube, the other end of the Barton tube is connected with the movement, the The movement is connected to the hands. When the above-mentioned pressure gauge is used to measure the pressure of the fluid, the Barton tube is affected by the f...
