Description

Technical Field

[0001] This utility model belongs to the field of protective equipment technology, and in particular relates to a transparent and visible dust cover. Background Technology

[0002] Most factory workplaces are in dusty environments, especially processing jobs such as woodworking, metal cutting, and cement making, which are more likely to generate powder and dust. Powder and dust can easily enter the interior of visual equipment (equipment with a display screen that needs to be observed) or settle on the surface of the visual equipment, affecting the observation. Furthermore, if the screen of the visual equipment is wiped by hand for easy observation during work, it can easily cause scratches or even damage. In acid mist environments, it can corrode the visual equipment, reducing its service life.

[0003] Therefore, it is necessary to study a visual dust cover to cover the designated location to protect the target area, thereby protecting the equipment from external environmental corrosion and damage, while also having an easy-to-install, easy-to-disassemble, replaceable or washable structure. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art by designing a transparent and visible dust cover.

[0005] To achieve the above objectives, the technical solution of this utility model is a transparent and visible dust cover, comprising a frame and a cover, characterized in that the cover is installed on the frame by a snap-fit ​​mechanism; a gasket is provided on the inner side of the frame to assist in the assembly of the cover; and the frame is provided with an observation window.

[0006] Preferably, the inner wall of the frame is formed with a fastener limiting boss and an assembly limiting boss.

[0007] Preferably, the bottom edge of the cover is designed and formed with a raised edge.

[0008] Preferably, a fastener is integrally formed on the raised edge.

[0009] Preferably, the fastener is formed with a fastening position to cooperate with the fastener limiting boss, and it is also designed with a pressing plate.

[0010] Preferably, the recessed depth of the assembly limiting protrusion on the inner wall of the frame is greater than that of the fastener limiting protrusion, so as to fit tightly against the cover during assembly.

[0011] Preferably, a gasket is also provided at the bottom of the frame, and the gasket can be made of silicone or EVA material.

[0012] Preferably, auxiliary mounting holes are pre-drilled on the inner side of the frame.

[0013] Compared with the prior art, the advantages of this utility model are as follows: The structure of this utility model is simple and reasonable, and it is easy to install and disassemble. Even if the cover is damaged, it can be replaced individually without replacing the whole thing. Gaskets made of EVA material are provided between the cover and the frame and at the bottom of the frame. EVA material has a certain degree of elasticity and is resistant to acids and alkalis, low temperatures, ozone, and mold. It can better fit the cover when it is placed inside the frame and the frame is placed on the surface of the object. The elasticity can reduce the possibility of gaps to a certain extent and prevent external gases or liquids from seeping into the interior that needs to be protected. In addition, adhesive tape or glue such as double-sided tape can be added to the gasket at the bottom of the frame to assist in positioning and installation. This allows the utility model to be customized and adhered to a specified plane according to the needs of covering and protection, or it can be connected and fixed by screws or other means through the auxiliary mounting holes pre-drilled on the inside of the frame. This provides a more effective connection and fixation when the utility model is installed perpendicular to the ground. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5As shown, this utility model is a transparent and visible dust cover, mainly composed of a frame 1 and a cover 2. The frame 1 has gaskets 3 installed on its inner side and bottom. The gaskets 3 can be made of elastic silicone or EVA material, preferably EVA material, because it also has the characteristics of acid and alkali resistance, low temperature resistance, ozone resistance, and mildew resistance, achieving better results in less than ideal factory processing environments, indirectly improving the practicality and service life of this utility model. The cover 2 is directly installed on the frame 1 with the gaskets 3 on its inner side by a snap-fit ​​connection. The cover 2 installed in the frame 1 is fixed and pressurized by the fasteners 21 and the assembly limiting protrusions 11, ensuring close contact with the gaskets 3 on the inner side of the frame 1. The gaskets 3 may even undergo elastic deformation. This assembly method and state allow the cover 2 and the gaskets 3 to fit better together, preventing external gases or liquids from seeping into the protected interior. The gasket 3 provided at the bottom of the frame 1 can be fitted with adhesive tape or glue such as double-sided tape to assist in positioning and installation. This allows the present invention to be customized and adhered to a specified plane according to the needs of covering and protection, or to be connected and fixed by screws or other means through the auxiliary mounting holes pre-drilled on the inner side of the frame. This provides a more effective connection and fixation when the present invention is installed perpendicular to the ground.

[0021] Regarding the assembly, it can be further explained that a raised edge 20 is designed and formed at the bottom edge of the cover 2, and a fastener 21 is integrally formed on the raised edge 20. The fastener 21 has a fastening position 210 formed on it to cooperate with the fastener limiting boss 10 for assembly. The inner side of the frame 1 not only has the fastener limiting boss 10 formed, but also has an assembly limiting boss 11 formed. The depth of the assembly limiting boss 11 on the inner wall of the frame 1 is greater than that of the fastener limiting boss 10. When the cover 2 is assembled, it will be set to fit tightly against it so that it is installed as tightly as possible against the gasket 3 on the inner side of the frame 1. Based on the above structural description, when the cover 2 is assembled into the frame 1 with the washer 3, one side of its protruding edge 20 should first be inserted into the gap between the assembly limiting protrusion 11 and the washer 3. Then, the side with the fastener 21 is pressed down. The fastener 21 has a certain elasticity and will contract when pressed down due to the protrusion of the fastener limiting protrusion 10 until the fastener limiting protrusion 10 falls into the fastener position 210, which can effectively position and assemble the cover 2. This structural design makes disassembly simple and quick. Since the fastener 21 also has a pressing plate 211, you only need to press the pressing plate 211 to make the fastener 21 disengage from the fastener limiting protrusion 10 and then bend it outward to release the cover 2 from the limiting fixation of the fastener limiting protrusion 10. This allows for replacement or touch operation or maintenance of the screen or object inside that needs protection.
