[0029] Specifically, both the touch screen 3 and the tempered glass 4 are set in the first mounting groove 11, and the tempered glass 4 is located on the upper surface of the touch screen 3, which serves to protect the touch screen 3 and transmit touch to the touch screen 3.

[0030] Specifically, panel 5 is used to limit touch screen 3 and tempered glass 4. By connecting panel 5 to upper housing 1, tempered glass 4 is pressed down. The lower surface of panel 5 is provided with several limiting members 51. The position of limiting members 51 corresponds to the snap-fit ​​position 12. The lower end face of limiting member 51 is provided with a cavity 52 for containing glue. The side wall of cavity 52 is provided with glue outlet hole 53. During installation, glue is first injected into cavity 52. ​​Then, panel 5 is connected to upper housing 1, so that extrusion column 13 extends into cavity 52, thereby squeezing glue out through glue outlet hole 53.

[0031] In this embodiment, the limiting member 51 does not extend into the first mounting groove 11, thereby avoiding the limiting member 51 from squeezing the sidewalls of the touch screen 3 and the tempered glass 4; at the same time, the limiting member 51 is fixed by applying glue to the sidewalls of the touch screen 3 and the tempered glass 4, that is, the limiting member 51 and the touch screen 3 are connected by glue to prevent shaking.

[0036] like Figure 3 As shown, in some embodiments, the first chamfer 41 of the tempered glass 4 protrudes from the upper housing 1; a second mounting groove 55 is provided on the panel 5, and the through hole 54 is located at the bottom of the second mounting groove 55; wherein the tempered glass 4 is flush with the bottom of the second mounting groove 55.

[0037] In this embodiment, the first chamfer 41 of the tempered glass 4 protrudes from the upper housing 1 to facilitate the panel 5 pressing down on the tempered glass 4, thereby serving as a limiting function.

[0038] In some embodiments, the height of the limiting member 51 is lower than the depth of the locking position 12.

[0039] In some embodiments, the upper surface of the extrusion column 13 is lower than the glue outlet 53, thereby preventing the extrusion column 13 from blocking the glue outlet 53, so that the fixed glue is partially located in the chamber 52.

[0040] In some embodiments, each sidewall of the first mounting groove 11 is provided with at least one snap-fit ​​position 12.

[0041] At least one embodiment also provides a PLC all-in-one machine, including: a panel 5, an upper housing 1, and a lower housing 2 arranged sequentially from top to bottom, the panel 5, the upper housing 1, and the lower housing 2 being adapted to be connected from bottom to top by a connector; a first mounting groove 11 is provided on the upper housing 1, and a touch screen 3 and a tempered glass 4 are arranged sequentially in the first mounting groove 11; a second mounting groove 55 is provided on the panel 5, and a face mask 6 is arranged in the second mounting groove 55; wherein, a plurality of snap-fit ​​positions 12 are provided on the four sides of the first mounting groove 11, and a plurality of limiting members 51 adapted to the snap-fit ​​positions 12 are provided on the lower surface of the panel 5.

[0042] In some embodiments, the lower end face of the limiting member 51 is provided with a chamber 52 for containing adhesive, and the side wall of the chamber 52 is provided with an adhesive outlet hole 53; an extrusion post 13 is provided in the snap-fit ​​position 12; the limiting member 51 is adapted to extend into the snap-fit ​​position 12 so that the adhesive in the chamber 52 is pressurized and applied to the junction of the side wall of the touch screen 3 and the tempered glass 4 through the adhesive outlet hole 53.

[0043] In some embodiments, the upper surface of the tempered glass 4 is provided with a first chamfer 41; the middle part of the panel 5 is provided with a through hole 54, and the lower surface of the through hole 54 is provided with a second chamfer 541; wherein the panel 5 is connected to the upper housing 1 so that the second chamfer 541 abuts against the first chamfer 41 of the tempered glass 4.

[0044] In some embodiments, the height of the limiting member 51 is lower than the depth of the snap-fit ​​position 12; the upper surface of the extrusion post 13 is lower than the dispensing hole 53.

[0045] In summary, the adhesive structure of this LCD touch screen and the limiting member 51 of the PLC all-in-one machine do not extend into the first mounting groove 11, thereby avoiding the limiting member 51 from squeezing the side wall of the touch screen 3 and the tempered glass 4; at the same time, by applying glue to the side wall of the touch screen 3 and the tempered glass 4 for fixation, that is, the limiting member 51 and the touch screen 3 are connected by glue to prevent shaking.
