Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauges, and particularly relates to a pressure gauge which is convenient to install. Background Technique

[0002] When a traditional pressure gauge (as shown in Figure 1 and Figure 2 ) is installed on a panel, accessories such as a mounting panel 5, mounting screws 7, and a mounting flange 8 are required. A hole is drilled in the mounting panel 5 according to the outer diameter of the pressure gauge product. The pressure gauge is installed on the mounting flange 8, and the pressure gauge with the mounting flange 8 already installed is placed on the mounting panel 5 with the hole already drilled, and the pressure gauge product is locked with the mounting screws 7. More accessories are required to achieve the installation, and the installation cost is high and the installation is cumbersome. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pressure gauge which is convenient to install, saves material costs and installation costs, and is more convenient to install, and can solve the problems of inconvenient installation and high cost of traditional pressure gauges in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A pressure gauge which is convenient to install, including a gauge body, a limiting plate is fixedly arranged at the top of the gauge body, an external thread is opened at the upper part of the gauge body, and the external thread extends upward to contact with the limiting plate, and the external thread extends downward to be able to be screwed with a locking flange.

[0006] Further, the locking flange is in a circular ring structure, and an internal thread matched with the external thread is arranged on the inner side of the locking flange. The locking flange can be locked with the external thread of the gauge body to ensure the installation stability of the pressure gauge.

[0007] Further, the gauge body is installed on a panel, and a mounting hole for installing the gauge body is opened on the panel. The diameter of the limiting plate is larger than the diameter of the mounting hole, which can ensure that the pressure gauge is installed into the mounting hole from top to bottom and is limited in a fixed position.

[0008] Further, the locking flange is located below the panel, and the locking flange is screwed with the external thread of the gauge body from below the panel. It only needs to be tightened from below, and the installation is convenient.

[0009] Further, a joint is arranged at the bottom of the gauge body, which is a connecting body for connecting the device or pipeline for measuring the medium and the pressure gauge.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] Compared with traditional pressure gauges, the present utility model has external threads provided on the gauge body and simplifies the installation fittings. It only needs to screw the locking flange onto the gauge body from below the panel to complete the installation of the pressure gauge, saving material costs and installation costs, and making the installation more convenient.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to Figure 3 , a pressure gauge that is convenient for installation, including a gauge body 1. A limit plate 2 is fixedly provided at the top of the gauge body 1. The limit plate 2 and the gauge body 1 can be fixedly connected by welding. An external thread 3 is provided on the upper part of the gauge body 1. The external thread 3 extends upward to contact the limit plate 2, and the external thread 3 extends downward to be able to be screwed with the locking flange 4, so as to ensure that the external thread 3 has sufficient height. The external thread 3 extends downward through the installation hole of the panel 5, so that the locking flange 4 can be screwed tightly with the external thread 3 from below.

[0020] Specifically, refer to Figure 4 , the locking flange 4 has an annular structure. An internal thread that cooperates with the external thread 3 is provided on the inner side of the locking flange 4. The locking flange 4 is screwed onto the gauge body 1 through the thread to ensure the installation stability of the gauge body 1.

[0021] In addition, the meter body 1 is installed on the panel 5. The panel 5 is provided with mounting holes for installing the meter body 1. The diameter of the limiting plate 2 is larger than the diameter of the mounting holes. The limiting plate 2 is located at the top of the panel 5 to limit the meter body 1.

[0022] Specifically, the locking flange 4 is located below the panel 5. The locking flange 4 is screwed onto the external thread 3 of the meter body 1 from below the panel 5. A joint 6 is provided at the bottom of the meter body 1. The locking flange 4 passes through the joint 6 and is sleeved on the meter body 1 and tightened with the external thread 3, so that the pressure gauge can be installed on the panel 5.

[0023] The installation process of the pressure gauge of the present utility model is as follows:

[0024] When installing the pressure gauge on the panel 5, only the locking flange 4 needs to be installed, specifically as follows:

[0025] Drill holes on the panel 5 according to the outer diameter of the pressure gauge, that is, the above-mentioned mounting holes. Place the pressure gauge on the panel 5 with the holes already drilled. Since the pressure gauge has an external thread 3 that matches the internal thread of the locking flange 4, only by tightening the locking flange 4 at the bottom of the panel 5 can the installation be completed. The installed pressure gauge is as Figure 5 shown.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
