[0002] Industrial automatic control instruments refer to instruments and equipment used to monitor, measure, adjust and control industrial production processes. Industrial automatic control instruments are widely used in production fields such as electricity, chemical industry, petroleum, metallurgy, machinery, light industry, building materials and food. They can accurately and timely monitor, control and adjust the production process to improve production efficiency, product quality and safety. In order to protect these instruments, it is often necessary to add protective mechanisms to their screens to effectively prevent the instrument screens from being worn, scratched, dusted or otherwise damaged.

[0003] The utility model with the existing authorization announcement number CN216451611U discloses a screen protection device for a display control instrument, including a protection seat, rectangular cavities are opened on both sides of the protection seat, and sliding rails are opened on the inner walls of one side of the two rectangular cavities, and arc plates are slidably connected to the inner walls of one side of the two rectangular cavities near the sliding rails, and the arc inner walls of the two arc plates are rotatably connected to connecting shafts, and the outer walls on the opposite sides of the two connecting shafts are fixed with the same cleaning roller by bolts, and the inner walls of one side of the two rectangular cavities are slidably connected to a transmission assembly that drives the cleaning roller to rotate.

[0004] The above technical solution, by pushing the connecting plate, drives the limiting block to slide through the limiting rod, drives the movement of the connecting rod and the arc plate through the L-shaped plate, and then drives the cleaning roller to move through the connecting shaft. There is no need to disassemble the protective device, thereby improving the cleaning efficiency of the screen of the display control instrument. This solution focuses on solving the technical problem of cleaning the surface of the protective plate, but does not consider the technical problem of how the protective device is sealed and stably connected to the surface of the control instrument display, and therefore there are certain safety hazards.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0045] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0046] Please refer to Figure 1-3 The instrument display screen protection structure of the utility model includes an instrument base 1, an instrument display 2 is fixedly connected to the upper surface of the instrument base 1, and a protection mechanism 3 is arranged above the instrument display 2. The protection mechanism 3 includes an inner frame 301 and an outer frame 302, the bottom surface of the inner frame 301 contacts the upper surface of the instrument base 1, the outer frame 302 is located on the outer surface of the inner frame 301, one end of the outer frame 302 is hinged to the back of the inner frame 301 through a latch mechanism, and the other end of the outer frame 302 is snap-fitted to the front of the inner frame 301 through a snap-fit ​​mechanism.

[0047] In specific implementation, the latch mechanism has two rotating seats 4 fixedly connected to the back of the inner frame 301, and four rotating pieces 5 fixedly connected to the bottom surface of the outer frame 302. The side surfaces of each group of rotating pieces 5 close to each other are in contact with the left and right side surfaces of the rotating seat 4. The rotating seat 4 is a rotating device of the inner frame 301, and the rotating piece 5 is a rotating device of the outer frame 302. A rotating rod 11 is arranged on the outer side of each rotating seat 4, and the end of each rotating rod 11 close to the rotating seat 4 passes through the rotating piece 5 and the rotating seat 4 in sequence, and extends to the outside of the rotating piece 5.

[0048] like Figure 5As shown, in a specific implementation, the buckle mechanism has two fixed frames 6 fixedly connected to the upper surface of the outer frame 302, and two limit seats 7 fixedly connected to the front of the inner frame 301 and corresponding to the positions of the fixed frames 6. The inner wall of each limit seat 7 is slidably connected with a sliding latch 8, and the end of the sliding latch 8 can be buckled on the outer edge of the upper end of the fixed frame 6. The front of each sliding latch 8 is fixedly connected with a pressing pad 10, and the back of each sliding latch 8 is fixedly connected with a spring 9, and the end of each spring 9 away from the sliding latch 8 is fixedly connected to the front of the inner frame 301. When in use, the outer frame 302 is rotated down by utilizing the relationship between the inner frame 301 and the outer frame 302 and the movable hinge. At this time, the pressing pad 10 is manually pressed, and the pressing pad 10 can drive the sliding latch 8 to slide. The spring 9 is used to fix the inner frame 301 and the sliding latch 8 respectively. The pressure is absorbed by the spring 9, and the outer frame 302 is rotated down to allow the fixed frame 6 to pass through the upper end of the sliding latch 8. At this time, the pressing pad 10 is released, and the sliding latch 8 is clamped to the outer edge of the upper end of the fixed frame 6 by the rebound force of the spring 9, thereby achieving the function of fixing the inner frame 301 and the outer frame 302.

[0049] like Figure 4 As shown, in order to improve the overall strength and sealing performance of this embodiment, a support bar 303 is fixedly connected to the inner wall of the outer frame 302, and an acrylic plate 304 is fixedly connected to the upper surface of the support bar 303. The outer surface of the acrylic plate 304 is in contact with the inner wall of the outer frame 302. A partition bar 305 is fixedly connected to the upper surface of the acrylic plate 304. The outer surface of the partition bar 305 is fixedly connected to the inner wall of the outer frame 302. A tempered glass 306 is fixedly connected to the upper surface of the partition bar 305. The outer surface of the tempered glass 306 is in contact with the inner wall of the outer frame 302. A sealing strip 307 is fixedly connected to the upper surface of the tempered glass 306. The outer surface of the sealing strip 307 is fixedly connected to the inner wall of the outer frame 302. This embodiment utilizes the cooperation of the support strip 303, the acrylic plate 304, the partition strip 305, the tempered glass 306 and the sealing strip 307 to protect the display 2, improve the overall sealing performance, and provide good observation. If the tempered glass 306 is broken by external force, the broken debris will be caught by the acrylic plate 304 and will not fall on the display 2, which provides double protection.

[0050] In this embodiment, the bottom surface of the inner frame 301 is connected to the instrument base 1 through a positioning mechanism. The positioning mechanism has four grooves 308 arranged on the bottom surface of the inner frame 301. The inner top wall of each groove 308 is rotatably connected with a rotating leg 309. The bottom surface of each rotating leg 309 is rotatably connected with a mounting leg 310. The upper surface of each mounting leg 310 is provided with three mounting holes 311. When in use, the device is placed as a whole on the instrument base 1, and the rotating legs 309 and the mounting legs 310 are manually rotated to align the mounting holes 311 with the reserved holes on the surface of the instrument base 1. The four mounting legs 310 can be fixed on the instrument base 1 by screws passing through the mounting holes 311.

[0051] In addition, in this embodiment, the positioning mechanism also includes a magnetic strip 12 arranged below the inner frame 301. The upper surface of the magnetic strip 12 is fixedly connected to the bottom surface of the inner frame 301. The magnetic strip 12 is used for auxiliary fixation.
