Description

Technical Field

[0001] The utility model relates to the technical field of panel mounted instruments, in particular to a display screen of a panel mounted instrument. Background Art

[0002] Panel-mounted instruments refer to instruments installed on a specific plane or structural member. These instruments are usually used for on-site observation and simple control operations. This type of instrument is usually installed on a panel that is easy for operators to access. It can be a screen, frame, channel or cabinet structure. They are mainly used for on-site operations, such as temperature survey meters, electric adjustment indicators, etc. These devices do not perform remote transmission or interlocking, and are mainly used for on-site observation and simple control loops. In addition, there is a specific type of on-site panel-mounted instrument, that is, the instrument is installed in the instrument panel on site, which is mainly used for on-site observation without remote transmission or interlocking operations.

[0003] This type of panel-mounted instrument is mostly used in industrial environments. Since there are many types of data monitored by equipment in industrial environments, the number of panel-mounted instruments installed at the terminal or control end will increase. The dense instruments and the small dial display content make it more difficult for workers with poor eyesight to read the data, reducing work efficiency. In addition, the display structure of the instrument panel is mostly fixed. When a fault occurs and the display does not appear, the instrument needs to be disassembled for inspection or replacement, which is more troublesome. Therefore, this problem is urgently needed.

[0022] To make the technical solution of the present utility model clearer and more definite to those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present utility model are not limited thereto.

[0023] As Figures 1 - 4 shown, a display screen of a disk-mounted instrument provided in this embodiment includes an outer frame 1 of the display screen. An inner display screen mounting panel 2 is integrally formed inside the outer frame 1 of the display screen. A display screen module 4 is detachably mounted on the display screen mounting panel 2. Lock holes 11 are provided on both sides of the outer wall of the display screen module 4. A lock head 12 is correspondingly arranged on one side outside the lock holes 11. The lock head 12 is connected to the bottom of a push plate 13, and a spring 14 is pressed against the back of the push plate 13.

[0024] A display screen plug-and-play wire tube 15 is integrally mounted on the back of the display screen module 4. The display screen plug-and-play wire tube 15 is used to connect to the instrument circuit board to realize data and power transmission, to realize the display of instrument monitoring data on the display screen module 4, and is also conducive to modular installation and maintenance.

[0025] The push plate 13 is slidably connected to the display screen mounting panel 2 through a limiting groove. The spring 14 is encapsulated in the limiting groove. The lock head 12 is slidably connected to the inner wall of the limiting groove. After the lock head 12 is separated from the lock hole 11, the top of the display screen module 4 extends beyond the display screen mounting panel 2, and the display screen module 4 can be manually pulled out.

[0026] A first magnifying glass 3 and a second magnifying glass 9 are slidably arranged in the gap between the display screen mounting panel 2 and the outer frame 1 of the display screen. Sliding grooves 5 are provided on both sides of the outer wall of the outer frame 1 of the display screen. A protruding slider 6 is slidably arranged in the sliding grooves 5. The first magnifying glass 3 and the second magnifying glass 9 can be used in combination or separately.

[0027] The protruding slider 6 is adhesively fixed to both the first magnifying glass 3 and the second magnifying glass 9. The slider slides in the sliding groove 5, and can drive the two groups of magnifying glasses to move parallel above the display screen mounting panel 2.

[0028] Indicator lights 7, indicator light labels 8 and button labels 10 are also provided on the display screen mounting panel 2.

[0029] The working principle of this device:

[0030] The first step: The outer frame 1 of the display screen is encapsulated on the instrument housing. The instrument circuit in the instrument housing is connected to the display screen module 4 through the display screen plug-and-play wire tube 15 to realize data and power transmission. At the same time, the display screen module 4 is clamped into the lock head 12 through the lock holes 11 on both sides, and the spring 14 is used to press to realize the locking of the display screen module 4 and the display screen mounting panel 2.

[0031] Step 2: During use, the user can push out the first magnifying glass 3 and the second magnifying glass 9 on both sides from the inner wall of the outer frame 1 of the display screen through the raised slider 6 and slide along the chute 5. The first magnifying glass 3 and the second magnifying glass 9 magnify and display the display screen module 4, the indicator light 7, the indicator light label 8, and the button label 10 at the bottom, improving the display size of the characters, facilitating the user's viewing, and reducing the work burden of the staff with poor eyesight.

[0032] Step 3: When it is found that the display screen module 4 fails, slide the push plate 13 to both sides. The push plate 13 squeezes the spring 14, and at the same time, the lock head 12 is withdrawn into the internal channel. The display screen module 4 loses the extrusion force and can be pulled out by an external force. At the same time, the display screen plug-in tube 15 is pulled out from the instrument circuit module, and a new display screen can be replaced, which is convenient and fast.

[0033] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
