[0016] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] For example, see Figure 1 and Figure 2 As shown, a digital pressure gauge that is easy to install quickly includes a housing and a viewing window 1 and a circuit board 2 arranged sequentially inside the housing. The housing includes an outer shell 3 and a cover (not shown). The outer shell 3 is a cylindrical structure with an internal mounting cavity and is open at both ends. One end is recessed with a mounting groove corresponding to the cover, and the other end protrudes with a limiting boss 31 corresponding to the viewing window 1. A plurality of mounting posts 32 protrude from the end of the limiting boss 31 near the cover. The end of the mounting post 32 near the cover is provided with a threaded hole, and the mounting bolts 4 of the viewing window 1 and the circuit board 2 are connected to the threaded hole.

[0020] In this technical solution, the housing is also equipped with conventional wiring holes and conventional connectors. After the window and circuit board are installed in the housing, the cover is a conventional disc structure and is fixed to the mounting groove of the housing by means of threaded connection or press-fit connection. When installing the window and circuit board, the window and circuit board are fixed to the mounting post of the housing at the same time by mounting bolts, which facilitates installation and improves installation speed and accuracy.

[0021] For example, see Figure 1 and Figure 2 As shown, a positioning boss 11 corresponding to the mounting post 32 is provided in the viewing window 1, and a positioning groove 12 corresponding to the mounting post 32 is recessed at one end of the positioning boss 11 near the mounting post.

[0022] In this technical solution, the positioning boss and the viewing window are integrally formed, and the positioning groove is slidably sleeved on the mounting post to facilitate quick positioning between the viewing window and the outer shell. The depth of the positioning groove is consistent with the length of the mounting post. That is, when the outer end face of the viewing window (the end face away from the circuit board) abuts against the inner end face of the limiting boss (the end face near the viewing window), the bottom wall of the positioning groove (the inner wall away from the circuit board) abuts against the end face of the mounting post.

[0023] For example, see Figure 1 and Figure 2 As shown, the positioning groove 12 is a U-shaped opening groove.

[0024] In this technical solution, the outer wall of the mounting column and the inner wall of the outer shell are connected by reinforcing ribs to improve the fixing strength of the mounting column; the positioning groove is a U-shaped opening groove, which avoids interference with the reinforcing ribs on the one hand, and facilitates quick positioning between the mounting column and the mounting column on the other hand.

[0025] For example, see Figure 1 As shown, the circuit board 2 has a first through hole corresponding to the mounting bolt 4, and the positioning boss 11 has a second through hole corresponding to the mounting bolt 4, which is connected to the positioning groove 12.

[0026] In this technical solution, the mounting bolts simultaneously install the viewing window and the circuit board onto the mounting post, thus completing the positioning between the housing, the viewing window, and the circuit board.

[0027] For example, see Figure 1 As shown, a display screen and several buttons are provided on the side of the circuit board 2 near the window 1. The window 1 is a transparent structure and has several functional holes corresponding to the buttons. The buttons pass through the functional holes and protrude from the window 1. A mask 5 is provided on the side of the window 1 away from the circuit board 2. The mask 5 has an observation port corresponding to the display screen and a mark corresponding to the buttons. A limiting groove corresponding to the mask 5 is recessed on the side of the window 1 near the mask 5.

[0028] In this technical solution, the mask is pasted onto the viewing window and installed as a whole. The viewing window is made of conventional materials such as acrylic glass and is integrally molded through processes such as injection molding. The observation port is hollowed out or transparent and corresponds to the display screen for observing the content displayed by the pressure gauge. Several through holes are also provided in the viewing window as functional holes corresponding to the buttons on the circuit board. The end of the button near the mask protrudes from the viewing window to ensure that the button can be pressed from one side of the mask to set the pressure gauge, etc. The mask is printed with text / letters / symbols to identify the function of the button, and the part corresponding to pressing the button is protruding to accommodate the protruding part of the button. A limiting groove is recessed on the outer end face of the viewing window near the mask, and the mask is pasted into the limiting groove.

[0029] For example, see Figure 1As shown, a limiting frame corresponding to the display screen protrudes from the side of window 1 near the circuit board.

[0030] In this technical solution, during window installation, a limiting frame is positioned around the display screen to improve the positioning accuracy between the window and the display screen.

[0031] For example, see Figure 1 As shown, the side wall of the limiting groove is recessed with several relief grooves, and the outer wall of the mask is protruded with several positioning ears corresponding to the relief grooves.

[0032] In this technical solution, the side wall of the limiting groove is recessed with three spaced relief grooves, and the circumferential surface of the mask has three positioning ears protruding. When the mask is attached to the viewing window, the three positioning ears are aligned with the corresponding relief grooves, thereby achieving rapid positioning of the mask and the viewing window and facilitating rapid positioning and installation of the mask.

[0033] In summary, this digital pressure gauge, which is easy to install quickly, has a simple structure. The viewing window and circuit board are directly fixed to the outer casing, which facilitates positioning and installation and improves the installation accuracy of the viewing window.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
