[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-2An industrial control LCD module includes a circuit board 1 and a display screen module 2. The display screen module 2 is mounted on the circuit board 1. Four positioning angle brackets 3 are fixed on the circuit board 1. Each positioning angle bracket 3 is an L-shaped structure. The four positioning angle brackets 3 are respectively located at the four corners of the display screen module 2. The side surfaces of the positioning angle brackets 3 are fitted with the side surfaces of the display screen module 2. The design of the positioning angle brackets 3 can improve the installation accuracy of the display screen module 2, so that the connection between the display screen module 2 and the circuit board 1 does not need to rely on the work experience of the staff, which is conducive to improving the installation quality and efficiency of the LCD module by the staff.

[0023] A fixing assembly is provided on the circuit board 1, and the fixing assembly includes two fixing plates 4, two positioning plates 5, two slide grooves 6, two sliders 7 and two springs 8. The two fixing plates 4 are fixed on the circuit board 1, and the two positioning plates 5 are respectively slidably mounted on the two fixing plates 4. The outer surface of the positioning plate 5 is provided with anti-slip textures, and the two positioning plates 5 are provided with inclined surfaces. The two slide grooves 6 are respectively opened on the top surfaces of the two fixing plates 4, and the two sliders 7 are respectively fixed on the two positioning plates 5, and the two sliders 7 are respectively slidably connected in the two slide grooves 6, and the slide grooves 6 and the sliders 7 are respectively connected to each other. The cross-sections are all T-shaped structures, which can prevent the slider 7 from escaping from the slide groove 6 and ensure the stability of the positioning plate 5. The groove wall of the slide groove 6 and the side of the slider 7 fit each other, one end of the two springs 8 are respectively connected to the groove walls of the two slide grooves 6, and the other ends of the two springs 8 are respectively connected to the two sliders 7. When the display screen module 2 is assembled in place, under the elastic force of the two springs 8, the two positioning plates 5 can jointly press the display screen module 2, thereby fixing the display screen module 2, which is beneficial to improve the stability of the display screen module 2 on the circuit board 1.

[0024] The specific working principle of the utility model is as follows:

[0025] When assembling the industrial control LCD module proposed by the utility model, the staff first applies glue on the back of the display screen module 2, and then assembles the display screen module 2 on the circuit board 1. In this process, the four corners of the display screen module 2 need to be respectively clamped on the four positioning angle brackets 3, and the display screen module 2 is fixed by using the four positioning angle brackets 3. The design of the positioning angle brackets 3 can improve the installation accuracy of the display screen module 2, so that the connection between the display screen module 2 and the circuit board 1 does not need to rely on the work experience of the staff, which is conducive to improving the installation quality and installation efficiency of the LCD module by the staff. In addition, in the process of connecting the display screen module 2 with the circuit board 1, the display screen module 2 will first squeeze the inclined surfaces of the two positioning plates 5. When the inclined surfaces of the two positioning plates 5 are squeezed, they can move synchronously and move away from each other, so that the two sliders 7 are squeezed with the two springs 8 respectively. When the display screen module 2 is assembled in place, under the elastic force of the two springs 8, the two positioning plates 5 can jointly press the display screen module 2, thereby fixing the display screen module 2, which is conducive to improving the stability of the display screen module 2 on the circuit board 1.
