Description

Technical Field

[0001] The utility model relates to the technical field of electrical switches, and more specifically, to a protective cover for an electrical switch. Background Art

[0002] In modern society, electrical equipment is widely used in various fields, from household life to industrial production. As a key component for controlling the on / off of electrical equipment, the safety and reliability of electrical switches are of crucial importance. Early electrical switches often did not have a dedicated protective cover, which led to many problems. In crowded places such as offices and schools, people are prone to accidentally touching the switch, resulting in electric shock accidents. With the improvement of safety awareness and the development of technology, protective covers for electrical switches began to appear. During the normal operation of electrical equipment, the protective cover is in a static state, but it effectively blocks external objects from directly contacting the switch. For example, when someone accidentally touches the electrical equipment, the protective cover can prevent fingers or other objects from directly touching the switch, and the protective cover protects the switch to a certain extent.

[0003] The existing protective covers for electrical switches use fixing devices, and screws firmly fix the protective cover on the supporting structure around the switch. The bolt - fixing method is relatively cumbersome during installation and disassembly, requires specific tools, and consumes a lot of time and manpower. In an industrial environment that is frequently vibrated, the bolt - fixed protective cover is more likely to become loose or damaged, making it inconvenient to protect the switch at this time.

[0023] Embodiment

[0024] Please refer to Figures 1-5 As shown, this embodiment provides a protective cover for an electrical switch, including a main body frame 1. The existing protective cover for an electrical switch uses a fixing device, and screws are used to firmly fix the protective cover on the support structure around the switch. The bolt fixing method is relatively cumbersome during installation and disassembly, requires specific tools, and consumes a lot of time and manpower. In an industrial environment where vibrations are frequent, the bolt-fixed protective cover is more likely to become loose or damaged, making it inconvenient to protect the switch at this time. Therefore, a plurality of elastic members 11 are fixedly connected to the inner wall of the main body frame 1, and one end of the elastic member 11 away from the main body frame 1 is fixedly connected to an elastic protective frame 12. The elastic protective frame 12 is made of high-strength plastic and has good toughness and impact resistance. The elastic protective frame 12 is located in the inner cavity of the main body frame 1. A protective component 2 is arranged on the inner wall of the main body frame 1, and the protective component 2 contacts the surface of the switch. A fixing component 3 is arranged at the bottom of the elastic protective frame 12, and the fixing component 3 is used to make the protective component 2 contact the surface of the switch. Among them:

[0025] The fixing component 3 includes two brackets 31 fixed to the bottom of the elastic protective frame 12. A connecting column 32 is slidably connected to the inner walls of the two brackets 31. Springs 33 are respectively fixedly connected to both ends of the connecting column 32. The two springs 33 are provided with a protective component 2 at their ends for fitting the protective component 2 to the switch. By pulling the protective component 2 to stretch the springs 33, the protective component 2 can be separated through the stretching of the springs 33. At this time, the moving device fits the elastic protective frame 12 to the surface of the switch, and by releasing the protective component 2, the springs 33 contract to fit the protective component 2 to the surface of the switch, thereby protecting and fixing the switch.

[0026] The improvement of this embodiment lies in:

[0027] Considering that the existing covers of electrical switches use fixing devices, and screws firmly fix the cover on the supporting structure around the switch. The bolt - fixing method is rather cumbersome during installation and disassembly, requiring specific tools and consuming a lot of time and manpower. In an industrial environment with frequent vibrations, the bolt - fixed cover is more likely to become loose or damaged, making it inconvenient to protect the switch. Therefore, by connecting the main frame 1 and the elastic protection frame 12 through the elastic member 11, and the elastic protection frame 12 made of high - strength plastic has good toughness and impact resistance, which can effectively protect the switch from vibrations and external impacts. Through the spring 33 and the slidable connecting column 32 in the fixing component 3, the fitting and separation of the protection component 2 and the switch are realized. The operation is simple, without the need for specific tools, saving the time and manpower for installation and disassembly, avoiding the problems of easy loosening and damage of the traditional bolt - fixing method in a frequently vibrating environment, ensuring continuous and stable protection of the switch. This structure enables the device to adapt to switches of different sizes and shapes, having good versatility. Through the stretching and contraction mechanism of the spring 33, the protection component 2 can closely fit the surface of the switch to fix the switch.

[0028] In order to enable the protection component 2 to fix the surface of the switch under the contraction of the spring 33, therefore, an elastic fixing plate 220 is fixedly connected to the end of the spring 33, and a connecting plate 22 is fixedly connected to the inner wall of the elastic fixing plate 220. Through the contraction of the spring 33, the elastic fixing plate 220 can fit on the surface of the switch to fix the switch.

[0029] In order to enable the elastic fixing plate 220 to rotate following the stretching of the spring 33, therefore, a fixed column 21 is hinged to the bottom of the connecting plate 22 using a hinge. Four empty slots are opened on the inner wall of the main frame 1, and the fixed column 21 is fixedly connected to the inner wall of the empty slot of the main frame 1. By connecting the connecting plate 22 and the fixed column 21 using a hinge, the stretching of the spring 33 can make the connecting plate 22 rotate on the surface of the fixed column 21, and the rotation of the connecting plate 22 can make the elastic fixing plate 220 rotate.

[0030] In order to enable the cooperation of the protection component 2 and the fixing component 3 to fix the pole switch, therefore, four groups of brackets 31 are fixedly connected to the top of the elastic protection frame 12. The four groups of brackets 31 are distributed at the four corners of the elastic protection frame 12. The springs 33 arranged on the inner walls of each group of brackets 31 are respectively fixedly connected to two elastic fixing plates 220. Through the connection of the two springs 33 in each group with the elastic fixing plate 220, two springs 33 can be arranged on the inner wall of the elastic fixing plate 220 for fixing the switch.

[0031] In order to make the elastic protective frame 12 fit on the surface of the switch with the elastic fixing plate 220 for protection, therefore, a protective cover 13 is fixedly connected to the top of the main body frame 1 of the main body frame 1. The protective cover 13 is in a plastic transparent arc state. By contacting the inner wall of the elastic protective frame 12 with the elastic fixing plate 220 on the surface of the switch, the protective cover 13 will cover the surface of the switch to protect the switch.

[0032] When the protective cover of the electrical switch of the present utility model is specifically used, the connecting plate 22 is pulled to stretch the spring 33. At this time, the connecting column 32 will slide on the inner wall of the bracket 31. Due to the stretching of the spring 33, the four connecting plates 22 can rotate with the fixed column 21. By fitting the elastic protective frame 12 on the surface of the switch, the connecting plate 22 is released to contract the spring 33 to fit the elastic fixing plate 220 on the surface of the switch. Due to the contraction of the spring 33, the elastic fixing plate 220 can be firmly attached to the surface of the switch to fix the switch.

[0033] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
