DETAILED DESCRIPTION

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0022] The following is combined with Figure 1-Figure 4 This embodiment is described in further detail.

[0023] See also Figure 1 and Figure 2In this embodiment, a chemical identification plate includes a substrate 200, display panels 201 are provided on both sides of the substrate 200, and pillars 210 are provided on the lower side of the substrate 200 and near both ends;

[0024] It also includes a protective cover 100 disposed outside the display board 201, and a cleaning component is disposed on the upper end surface of the protective cover 100, and the cleaning component is used to scrape and clean the side of the protective cover 100;

[0025] The cleaning assembly includes a mounting box 120, a mounting cavity 211 is provided inside the mounting box 120, a cleaning sweeping plate 130 for scraping the side of the protective cover 100 is provided outside the mounting box 120, and a driving assembly is provided in the mounting cavity 211 for driving the cleaning sweeping plate 130 to move back and forth.

[0026] In this embodiment, the base plate 200 is rectangular, the upper end of the support 210 is fixedly connected to the lower side of the base plate 200, and the lower end of the support 210 is provided with a bottom plate, which is fixed to the ground by bolts, thereby preferably supporting the chemical identification plate so that it can be used in a chemical workshop;

[0027] Among them, one side of the display board 201 is painted or spray-painted to present the content to be displayed (such as dangerous goods, flammable and explosive, etc.) on the display board 201, and the other side of the display board 201 is glued to one side of the substrate 200, thereby preferably forming a chemical identification board;

[0028] The protective cover 100 is made of a transparent acrylic plate material, which has good anti-corrosion performance. Through the setting of the protective cover 100, it can be set outside the display board 201, thereby protecting the logo content on the display board 201 and the display board 201 from corrosion damage. At the same time, since the protective cover 100 is transparent, the logo content on the display board 201 can be displayed;

[0029] Among them, one end of the protective cover 100 is open, so that the protective cover 100 can be preferably covered on the outside of the display board 201 through the opening. In order to ensure the sealing performance of the protective cover 100, when the protective cover 100 is covered on the outside of the display board 201, its open end and the side of the display board 201 are sealed by glass glue, so that the protective cover 100 is closed and a better protective effect is achieved;

[0030] The drive assembly is configured to drive the cleaning sweeping plate 130 to reciprocately clean the outer side of the protective cover 100, thereby keeping the outer side of the protective cover 100 clean, so that the marking content on the display board 201 can be clearly displayed;

[0031] In actual use of this example, a sponge (not shown in the figure) is provided on the side of the cleaning sweeping plate 130 facing the protective cover 100 so as to contact the side of the protective cover 100, so as to prevent the cleaning sweeping plate 130 from scratching the outer surface of the protective cover 100 and affecting the clear display of the identification content on the display board 201.

[0032] In this embodiment, the upper end of the installation cavity 211 is opened, and a mounting cover 140 is provided at the opening of the installation cavity 211. The mounting cover 140 is fixed to the upper end surface of the installation box 120 by bolts, so that the installation cavity 211 is sealed to prevent the entry of external dust, thereby keeping the drive assembly clean.

[0033] Combination Figure 3 and Figure 4 As shown, the driving assembly includes a fixed plate 220, and a rotatable sprocket 440 is provided on one side of the fixed plate 220 and at both ends. The sprockets 440 at both ends are connected by a chain 420, and a block-shaped hub 450 is provided on the chain 420;

[0034] The driving assembly also includes a card block 410, which is provided with a card slot 411. The block-shaped hub 450 extends into the card slot 411 and slides. A limit block 460 perpendicular to the card block 410 is provided on one side surface of the card block 410 along the moving direction of the chain 420. A slide groove 121 is provided on the outer wall of the installation box 120 along the moving direction of the chain 420. The limit block 460 is slidably arranged in the slide groove 121, and the cleaning sweeping plate 130 is connected to the side of the limit block 460 extending out of the slide groove 121.

[0035] In this embodiment, the sprockets 440 are rotatably mounted on the fixed plate 220 via a rotating shaft. The sprockets 440 and the chains 420 are arranged so that the chains 420 can move between the sprockets 440, thereby driving the block-shaped hub 450 to move along the chains 420.

[0036] In actual use, a motor 430 is disposed on the other side of the fixed plate 220, and the motor 430 is used to drive the corresponding sprocket 440 to rotate, thereby realizing the movement of the chain 420;

[0037] Among them, through the cooperation setting of the limit block 460 and the slide groove 121, the limit block 460 is located in the slide groove 121 and slides, so that the slide groove 121 can limit the sliding distance and sliding direction of the limit block 460, and further limit the moving distance and direction of the card block 410;

[0038] The movement track of the chain 420 located above the two sprockets 440 is the upper track, and the movement track of the chain 420 located below the two sprockets 440 is the lower track; wherein, through the coordinated arrangement of the block hub 450, the card block 410 and the card slot 411, when the chain 420 drives the block hub 450 to move on the upper track, it can drive the card block 410 to move along the upper track, even if the limit block 460 drives the cleaning sweeping plate 130 to move along the upper track, at this time, when the card block 410 moves and drives the limit block 460 on the chain 420 When the upper track moves to one end of the slide groove 121, the slide groove 121 will limit the block 410 to be stationary for a short time. At this time, the block hub 450 will slide from the upper track to the lower track as the sprocket 440 rotates, thereby driving the block hub 450 to slide along the slot 411, so that it slides from the upper end to the lower end. Even if the movement direction of the block hub 450 on the chain 420 is switched, it can move along the lower track, drive the block 410 to move along the lower track, and finally drive the cleaning sweeping plate 130 to move in the opposite direction along the lower track;

[0039] Similarly, when the block 410 moves and drives the limit block 460 to move to the other end of the slide groove 121 on the lower track of the chain 420, the slide groove 121 will limit the block 410 to be temporarily stationary. At this time, the block hub 450 switches the movement direction as the chain 420 moves, thereby allowing the chain 420 to continuously rotate to achieve the reciprocating movement of the cleaning sweeping plate 130, thereby allowing the cleaning sweeping plate 130 to reciprocate and clean the outer side of the protective cover 100.

[0040] In this embodiment, the length of the cleaning sweeping plate 130 is matched with the height of the protective cover 100, so that the cleaning sweeping plate 130 can evenly clean the outer side surface of the protective cover 100 when working.

[0041] In this embodiment, the two end surfaces of the fixed plate 220 are fixed to the two end surfaces of the installation box 120 by screws, so that the fixed plate 220 is fixedly installed in the installation cavity 211; wherein, when the fixed plate 220 is fixedly installed in the installation cavity 211, the chain 420 can drive the block-shaped hub 450 to extend into the slot 411, and abut the block 410 to make the limit block 460 extend into the slide groove 121, thereby realizing the installation of the drive component.

[0042] Working principle: First, in chemical production, the protective cover 100 is set outside the display board 201, so that it can protect the logo content on the display board 201 and play a role in corrosion and aging; when the outer side of the protective cover 100 needs to be cleaned, the motor 430 is started to drive the sprocket 440 to rotate, thereby driving the block hub 450 on the chain 420 to move with the chain 420, and with the cooperation of the block 410, the limit block 460 and the slide groove 121, the block hub 450 can be switched on the upper and lower tracks of the chain 420, so that the cleaning sweeping plate 130 can reciprocate, thereby reciprocating cleaning of the protective cover 100.

[0043] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
