Description

Technical Field

[0001] The utility model relates to the technical field of electrical switch protection, in particular to a switch protection structure. Background Art

[0002] In daily life and industrial production, switches are basic devices that control the on and off of circuits, and their safety performance directly affects the safe operation of electrical systems.

[0003] Therefore, when installing an electrical switch, a protective cover with a button protection function needs to be set on the switch surface to protect the button switch to prevent the electrical equipment from malfunctioning and stopping operation due to accidental touching of the switch during use.

[0004] However, most existing switch protection structures only protect their buttons from accidental touches through sealing covers, and the protective buttons cover all buttons. Before using some commonly used buttons, the protective structure still needs to be flipped open. At the same time, the remaining buttons that do not need to be controlled are also exposed, which poses a risk of accidental touches.

[0005] Therefore, the utility model proposes a protection structure for a switch. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a switch protection structure.

[0007] To achieve the above-mentioned object, the present invention adopts the following technical solution: a switch protection structure, comprising a switch mounting base, on which a first button and a second button are sequentially arranged, a rotating cover plate is rotatably connected to the switch mounting base, and a protection component is provided on the switch mounting base above the first button;

[0008] The protection component includes a protection plate, a sleeve is provided on the protection plate, a spring is provided in the sleeve, and push rods are slidably connected to both ends of the spring in the sleeve.

[0009] As a preferred embodiment, the protective plates are each provided with a rotating seat at one end thereof that is away from the push rod, and the rotating seat is in contact with the push rod.

[0010] The beneficial effect of adopting the above further solution is: by mutually locking the rotating seat and the push rod, the rotating seat after locking cannot rotate under the action of the push rod, thereby preventing the rotating seat from rotating during use and causing the limit pin to fall off from the limit groove, so that the protective component is separated from the first button.

[0011] As a preferred embodiment, a connecting rod is provided at the bottom of the rotating seat, and the bottom of the connecting rod is rotatably connected to a limiting pin.

[0012] The beneficial effect of adopting the above-mentioned further scheme is: through the setting of the connecting rod and the limit pin, when the rotating seat and the push rod are in a locked state, the limit pin is inserted into the limit groove for limiting and fixing. When the push rod is separated from the rotating seat, the limit pin can be pulled out from the limit groove through the connecting rod under the action of the lever, thereby releasing the limiting state of the protective component and the first button, so that the first button can be used normally.

[0013] As a preferred embodiment, limiting grooves are provided on both sides of the first button, and the limiting grooves and the limiting pins are engaged with each other.

[0014] The beneficial effect of adopting the above-mentioned further scheme is: through the limit groove opened on the first button, it is possible to engage with the limit pin, and the protective component after engagement is connected to the first button as a whole. At this time, the protective plate protects the top of the first button under the action of the switch mounting seat, so that the first button cannot be pressed down to trigger.

[0015] As a preferred embodiment, a sliding seat is provided on the top of the rotating cover plate, and there are two sliding seats in total, and a slide plate is slidably connected between the two sliding seats.

[0016] The beneficial effect of adopting the above further solution is: when the first button is used less frequently, the first button can be protected by sliding the slide to the top of the first button. Compared with the effect of protecting the first button by the protective component, this method is more convenient and quick, but after the machine stops running, the first button can be protected more stably by the protective component.

[0017] As a preferred embodiment, an iron sheet is provided at the bottom of the slide plate, and magnetic sheets are provided at both ends of the sliding seat on the rotating cover plate, and the magnetic sheets and the iron sheet are magnetically attracted to each other.

[0018] The beneficial effect of adopting the above further scheme is: the skateboard is limited by the mutual magnetic attraction between the iron sheet and the magnetic sheet. When the skateboard is above the first button, it can be limited by the mutual magnetic attraction between the iron sheet and the magnetic sheet close to the first button. When the skateboard is retracted into the sliding seat, the skateboard can be limited by the mutual magnetic attraction between another magnetic sheet and the iron sheet.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are:

[0020] 1. In the present invention, the first button can be protected by the provision of a protective assembly. When the device is not in use, the rotating cover can be placed above the first button and the protective plate can be pressed downward. At this time, the spring contracts and deforms, driving the limit pin to tilt to both sides until the limit pin is inserted into the limit groove, and the spring deformation is restored. At this time, the protective assembly can protect the first button to prevent the first button from being accidentally touched when it is not used for a long time.

[0021] 2. In the present invention, the first button can be further provided with double-layer protection by the slide, and when the first button needs to be pressed during use, the protective component is removed. At this time, the first button can be temporarily protected by the slide, and the slide is limited by the mutual magnetic attraction between the iron sheet and the magnetic sheet. When the slide is above the first button, the iron sheet and the magnetic sheet close to the first button can be magnetically limited by each other. When the slide is retracted into the sliding seat, the slide can be limited by the mutual magnetic attraction between another magnetic sheet and the iron sheet. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-4 As shown, the utility model provides a technical solution: a switch protection structure, including a switch mounting base 1, a first button 11 and a second button 12 are sequentially arranged on the switch mounting base 1, a rotating cover plate 2 is rotatably connected to the switch mounting base 1, and a protection component 3 is arranged on the switch mounting base 1 above the first button 11; the protection component 3 includes a protection plate 31, a sleeve 32 is provided on the protection plate 31, a spring 33 is provided in the sleeve 32, and push rods 34 are slidably connected at both ends of the spring 33 in the sleeve 32, and a rotating seat 35 is provided at one end of the protection plate 31 away from the push rod 34, the rotating seat 35 and the push rod 34 are in contact with each other, and a connecting rod 36 is provided at the bottom of the rotating seat 35, connecting The bottom of the rod 36 is rotatably connected to the limit pin 37, and a limit slot 111 is provided on both sides of the first button 11. The limit slot 111 and the limit pin 37 are mutually engaged. The first button 11 can be protected by the setting of the protective component 3. When the device is not in use, the rotating cover 2 can be placed above the first button 11 and the protective plate 31 can be pressed downward. At this time, the spring 33 contracts and deforms, driving the limit pin 37 to tilt to both sides until the limit pin 37 is inserted into the limit slot 111, and the spring 33 is deformed and restored. At this time, the protective component 3 can protect the first button 11 to prevent the first button 11 from being accidentally touched when it is not used for a long time, thereby solving the technical problem of accidental touch of the switch.

[0032] A step further, such as Figure 2-Figure 4 As shown: a sliding seat 22 is provided on the top of the rotating cover 2, and there are two sliding seats 22 in total, and a slide plate 21 is slidably connected between the two sliding seats 22. When the first button 11 is used less frequently, the slide plate 21 can be slid to the top of the first button 11 to protect the first button 11. Compared with the effect of protecting the first button 11 by the protection component 3, this method is more convenient and quick. However, after the machine stops running, the first button 11 can be protected more stably by the protection component 3, which solves the technical problem of switch protection during use.

[0033] The above solution also has the problem that the slide plate 21 is easy to slide in the slide seat 22. Figure 4As shown: In this solution, an iron sheet 24 is provided at the bottom of the slider 21, and magnetic sheets 23 are provided at both ends of the sliding seat 22 on the rotating cover 2. The magnetic sheets 23 and the iron sheet 24 are magnetically attracted to each other, and the slider 21 is limited by the mutual magnetic attraction between the iron sheet 24 and the magnetic sheet 23. When the slider 21 is above the first button 11, the iron sheet 24 and the magnetic sheet 23 close to the first button 11 can be magnetically limited by each other. When the slider 21 is retracted into the sliding seat 22, the slider 21 can be limited by the mutual magnetic attraction between another magnetic sheet 23 and the iron sheet 24.

[0034] Working principle:

[0035] like Figure 1-4 As shown, when in use, the switch mounting base 1 is set in the specified position, the first button 11 can be connected to the control interface with general frequency of use, and the second button 12 is connected to the control interface of emergency stop. At this time, when the second button 12 needs to be used, the rotating cover 2 can be flipped upward. Due to the setting of the rotating cover 2, the second button 12 requires a specified operation to be opened, but when the first button 11 needs to be used, the protective component 3 is removed from the first button 11, so that the first button 11 can be pressed and used normally. However, during use, the protective component 3 that is easy to open is also required to protect the first button 11. At this time, the slide plate 21 is slid to the top of the first button 11, and the magnetic sheet 23 and the iron sheet 24 are magnetically attracted to each other to limit the slide plate 21. When the slide plate 21 is used, the first button 11 can be pressed by sliding the slide plate 21 into the sliding seat 22.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
