[0040] To make the objectives, technical solutions and advantages of the embodiments clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the drawings in the embodiments. Obviously, the described embodiments are some but not all of the embodiments. Based on the embodiments in the embodiments, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the embodiments.

[0041] The following will be described with reference to the drawings. Figures 1-8 The control box panel 100 of the embodiments is described. The control box panel 100 of the embodiments is mainly used to be installed on a control box, to seal the control box against water, to improve weather resistance, and to improve the protection performance of the control box.

[0042] The following will be described with reference to the drawings. Figures 1-5 First, the structure of the control box panel 100 is described. The control box panel 100 provided by the embodiments mainly includes:

[0043] The face frame 10 mainly plays a supporting role and serves as a mounting carrier for the following components. The middle part of the face frame 10 is hollowed out to form a display area. The front surface of the face frame 10 is provided with a mounting area 11 on at least one side of the display area. The mounting area 11 can be arranged on one side or adjacent two sides of the front surface of the face frame 10. The position of the mounting area 11 is specifically arranged according to the need. The back surface of the face frame 10 is provided with a sealing groove 13, that is, the sealing groove 13 is arranged on the back surface of the face frame 10.

[0044] It should be noted that the "front surface" and "back surface" refer to the position of the control box panel 100 relative to the box body 70 after installation. The surface facing outward of the box body 70 is the "front surface", and the surface facing inward of the box body 70 is the "back surface".

[0045] For example, the face frame 10 can be square-shaped to facilitate matching and installation with the square-shaped box body 70.

[0046] The display screen 50 is installed in the display area and is mainly used to display various test data.

[0047] The control board 20 is adapted to the mounting area 11 and is mounted on the mounting area 11. The mounting area 11 is formed as a groove-like structure, and the control board 20 can be embedded in the groove to achieve positioning.

[0048] The sealing ring 12 is mounted on the sealing groove 13 and partially protrudes from the sealing groove 13. The protruding part of the sealing ring 12 serves as a sealing function. After the control box panel 100 is mounted on the control box, the protruding part of the sealing ring 12 of the control box panel 100 abuts the side wall of the opening 71 of the cabinet 70, thereby sealing the cabinet 70.

[0049] The tempered glass 30 has a key slot 31 formed on the surface, which facilitates the installation of the key assembly 40. In this embodiment, the tempered glass 30 is mounted on the face frame 10, which can provide better protection, corrosion resistance, oxidation resistance, and strong waterproof ability. Specifically, the strength of the tempered glass 30 is several times higher than that of ordinary glass, and it is resistant to bending. In addition, it is safe to use, and its carrying capacity is increased to improve its fragile nature. Even if the tempered glass 30 is broken, it will be small and sharp, greatly reducing the harm to the human body. The tempered glass 30 has 3-5 times higher resistance to sudden temperature changes than ordinary glass, and can generally withstand temperature changes of 250 degrees or more, which has a significant effect on preventing thermal cracking.

[0050] The key assembly 40 is inserted into the key slot 31 and is sealingly connected with the key slot 31, so that only the keys that need to be pressed are exposed outside the tempered glass 30, as shown, which facilitates manual operation. The rest of the key assembly 40 is sealed below the tempered glass 30, which serves as a waterproof seal. Figure 3

[0051] The tempered glass 30 can be fixed to the front of the face frame 10 by glue sealing. The key assembly 40 is tightly connected with the control board 20 and is electrically connected, i.e., the key assembly 40 is tightly connected with the control board 20 and is electrically connected.

[0052] The control box panel 100 of this embodiment is sealed and assembled together by the face frame 10, the tempered glass 30, the control board 20, and the key assembly 40, which serves as a waterproof seal and has good weather resistance and long service life.

[0053] In a specific embodiment, as shown in Figures 1-5 ​As shown, the key assembly 40 comprises silica gel keys 41 and a key pressing frame 42, the silica gel keys 41 and the key pressing frame 42 are assembled to form the key assembly 40, the silica gel keys 41 are installed on the key pressing frame 42, the key pressing frame 42 is sealedly installed on the key slot 31 of the tempered glass 30 through sealing glue, the size and shape of the key pressing frame 42 match the size and shape of the key slot 31 of the tempered glass 30, after the key pressing frame 42 is pressedly installed on the key slot 31, in order to ensure the sealing, the sealing glue is applied at the joint of the key slot 31 and the key pressing frame 42, so as to avoid the water vapor from entering the interior of the tempered glass 30 and ensure the sealing. Compared with the common keys, the silica gel keys 41 have a longer service life, and have excellent heat resistance, cold resistance, environmental resistance, electrical insulation, fatigue resistance and other characteristics.

[0054] In one specific embodiment, the silica gel keys 41 comprise silica gel bodies 411 and a plurality of buttons 412 arranged on the surface of the silica gel bodies 411, the key pressing frame 42 is provided with through holes corresponding to the buttons 412, if the buttons 412 are square, the through holes are also square, and if the buttons 412 are circular, the through holes are also circular. The buttons 412 pass through the through holes one by one and the silica gel bodies 411 are press-fitted in the key pressing frame 42, and specifically, a groove can be formed on the surface of the silica gel body 411, and the bottom surface of the key pressing frame 42 is press-fitted in the groove, so that the two are tightly connected.

[0055] In one specific embodiment, in order to reliably install the key pressing frame 42 on the tempered glass 30, the opposite sides of the key pressing frame 42 are provided with a plurality of buckles or protrusions, the upper surface of the key pressing frame 42 is provided with an annular flange, the key pressing frame 42 is also made of silica gel and has a certain elasticity, when the key pressing frame 42 is pressed downward, the buckles or protrusions are clamped to the back surface of the tempered glass 30, and the annular flange is tightly pressed on the front surface of the tempered glass 30, and the key pressing frame 42 is clamped to the key slot 31 of the tempered glass 30 through the buckles and is sealed through the sealing glue. Thus, the stability between the installed key pressing frame 42 and the tempered glass 30 is high and the sealing is good.

[0056] According to one control box panel 100 of the embodiment, as shown in Figure 2 As shown, the control panel 20 is provided with self-resetting keys 21, the self-resetting keys 21 correspond to the buttons 412 one by one, and the self-resetting keys 21 have a self-resetting function and can help the buttons 412 automatically reset after being pressed. As shown in Figure 4 and Figure 5As shown, a cavity is formed inside the button 412. The bottom surface of the silicone body 411 is provided with an exhaust groove 413 that communicates with the cavity of the button 412. The exhaust groove 413 is used to balance the pressure difference inside and outside the button, and at the same time meets the functions of button switching and waterproofing. A guide hole 414 is formed on the bottom surface of each button 412. The self-reset button 21 is interference-fitted into the guide hole 414 and connected to the button 412, so that the self-reset button 21 and the button 412 are reliably and securely connected.

[0057] According to a control box panel 100 of this embodiment, the bottom of the silicone body 411 is provided with two rows of oppositely arranged inverted buckles 415. The inverted buckle 415 is a column with a thin base and a thick head. The control board 20 has two rows of corresponding through holes on opposite sides of the self-reset button 21. The inverted buckles 415 are inserted into the through holes one by one. Due to the structure of the inverted buckle 415 being larger at one end and smaller at the other end, after being inserted into the through hole, the larger end of the inverted buckle 415 is stuck outside the through hole, thereby effectively preventing the inverted buckle 415 from coming out of the through hole. This ensures a reliable connection between the silicone body 411 and the control board 20.

[0058] To facilitate the assembly of the control board 20 and prevent it from being installed backwards, a control box panel 100 according to this embodiment has a foolproof post on one side of the mounting area 11, and the control board 20 has a foolproof hole. The control board 20 is fitted onto the foolproof post and the mounting area 11 of the face frame 10 through the foolproof hole to prevent foolproof assembly.

[0059] To facilitate the locking of the control box panel 100 after installation in the control box, in one specific embodiment, the control box panel 100 further includes a lock body 60. One end of the lock body 60 is a lock head, and the other end is a lock tongue. The lock body 60 passes through the installation area 11. The lock head of the lock body 60 protrudes from the front of the face frame 10. The lock head is the side that is easy to open with a key. The lock head may have a triangular protrusion to facilitate opening with a corresponding keyhole. The lock tongue of the lock body 60 is located on the back of the face frame 10 and extends out of the side of the lock body 60. When the lock head rotates, the lock tongue rotates accordingly. The control plate 20, the silicone button 41, and the button frame 42 are each provided with mounting holes for the lock head to pass through. The mounting hole of the silicone button 41 is provided with a silicone plug 43 to cover the lock head, preventing the lock head from being exposed and maintaining the overall aesthetic appearance of the button assembly 40.
