the device comprises a protective cover plate 11, a transparent observation groove 12, an expansion link 13, a clamping part 14, a warning plate 15, an anti-misoperation screw 16, an expansion hole 17, an elastic knob 18, an air switch 19 and a switch handle 20.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Please refer to fig. 1 to 3.

The embodiment provides a novel warning sign of air switch of maloperation function is prevented in area, including protection cover plate 11, be provided with the transparent observation groove 12 that is used for covering switch handle 20 on the protection cover plate 11.

The open state of the switch handle 20 can be directly observed through the transparent observation groove 12, and the malfunction can be prevented.

The two sides of the protection cover plate 11 are respectively provided with a telescopic rod 13 in a telescopic manner, and each telescopic rod 13 is provided with a clamping part 14 for clamping two sides of an air switch 19.

In this embodiment, the telescopic rod 13 is L-shaped. One side of the L-shaped telescopic rod 13 is the gripping portion 14, and the other side is a rack portion with teeth.

Specifically, telescopic holes 17 for telescopic the telescopic rods 13 are respectively formed in two sides of the protective cover plate 11, and the telescopic rods 13 can slide in the telescopic holes 17.

The protective cover plate 11 is further provided with a mounting hole for mounting the elastic knob 18, one end of the elastic knob 18 is provided with a gear, and the gear is meshed with the rack portion. Therefore, by rotating the tightening knob 18, the two telescopic rods 13 are synchronously extended outwards or retracted inwards. When retracted, the two clamping portions 14 are available for clamping on both sides of the air switch 19. By utilizing the characteristic of the telescopic rod 13, the warning board can be fixed on air switches 19 with different sizes, and the universality is strong.

The protection cover plate 11 is also connected with a warning plate 15 with warning marks. Specifically, the warning plate 15 is connected to the bottom of the protective cover plate 11. The content of the warning mark is used for reminding an operator to prevent misoperation. The content can be characters or pictures.

Furthermore, an anti-misoperation screw 16 for preventing the misoperation of the switch handle 20 is also arranged on the protective cover plate 11. In general, when the switching handle 20 is switched from the open state to the closed state, the switching handle 20 needs to be pushed up. In this embodiment, when the switch handle 20 is in the open state, the misoperation prevention screw 16 is used to prop against the switch handle 20, so as to prevent the switch handle 20 from being mistakenly moved upwards, thereby greatly enhancing the safety.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "including," and "having" are intended to be inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

When an element or layer is referred to as being "on" … … "," engaged with "… …", "connected to" or "coupled to" another element or layer, it can be directly on, engaged with, connected to or coupled to the other element or layer, or intervening elements or layers may also be present. In contrast, when an element or layer is referred to as being "directly on … …," "directly engaged with … …," "directly connected to" or "directly coupled to" another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship of elements should be interpreted in a similar manner (e.g., "between … …" and "directly between … …", "adjacent" and "directly adjacent", etc.). As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region or section from another element, component, region or section. Unless clearly indicated by the context, use of terms such as the terms "first," "second," and other numerical values herein does not imply a sequence or order. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

Spatially relative terms, such as "inner," "outer," "below," "… …," "lower," "above," "upper," and the like, may be used herein for ease of description to describe a relationship between one element or feature and one or more other elements or features as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below … …" can encompass both an orientation of facing upward and downward. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
