Description

Technical Field

[0001] This utility model relates to the field of electrical switches, and in particular to a protection component and its electrical switch. Background Technology

[0002] Electrical switches are devices used to control the flow of current. They are widely used in various places such as homes, industries, and commerce. When the switch is in the "on" state, current can pass through, and when it is in the "off" state, the current is cut off. The working principle of a switch is usually based on the connection and disconnection of a circuit.

[0003] When using switches on machinery in some factories, they are usually installed directly in a conspicuous and easily accessible place using fixing components, so that personnel can operate the electrical switches. However, because the electrical switches are installed in conspicuous and easily accessible places, they are also easily touched by external objects or pedestrians, which can lead to scratches and damage to the electrical switches, or even change their switching state, thereby reducing the stability of the electrical switches and thus having certain defects.

[0034] 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.

[0035] This utility model provides, for example Figure 1-3 The protective component shown is a type of protective component.

[0036] Example 1: Includes a mounting plate 1, a protective housing 2, a cover 3, positioning posts 4, a locking assembly 5, a transparent plate 6, and a handle 7. The mounting plate 1 is used to install an electrical switch. The protective housing 2 is located on the front of the mounting plate 1. The top of the cover 3 is provided with a hinge, and the cover 3 is rotatably connected to the front of the protective housing 2 via the hinge. The protective housing 2 and the cover 3 are used to protect the electrical switch. Rotating the cover 3 allows direct operation of the electrical switch. The end of the positioning post 4 is fixedly connected to the mounting plate 1. The positioning post 4 is slidably engaged inside the protective housing 2, and the four positioning posts 4 are located at the four corners of the inner cavity of the protective housing 2, thereby limiting the movement of the protective housing 2. The locking assembly 5 is located inside the protective housing 2 and engages with the positioning posts 4, thereby ensuring the stability of the protective housing 2 installation. The transparent plate 6 is fixedly embedded on the front of the cover 3, allowing observation of the electrical switch inside the protective housing 2 through the transparent plate 6. The handle 7 is fixedly connected to the bottom of the cover 3, facilitating the opening and rotation of the cover 3.

[0037] Furthermore, the locking assembly 5 includes a fixing plate 51 and a locking rod 52. The fixing plate 51 is fixedly connected to one side of the inner wall of the protective housing 2. A connecting hole is provided at the end of the fixing plate 51. The outer wall of the locking rod 52 is slidably sleeved with the inner cavity of the connecting hole. A locking groove is provided on one side of the positioning post 4. The outer wall of the locking rod 52 is slidably engaged with the inner cavity of the locking groove. Thus, the locking rod 52 is engaged between the fixing plate 51 and the positioning post 4, which can lock the protective housing 2 and ensure the stability of the installation of the protective housing 2.

[0038] Furthermore, the locking assembly 5 also includes a mounting groove 53, a connecting block 54, and a limiting assembly 56. The mounting groove 53 is located on the front of the fixing plate 51. The connecting block 54 is slidably disposed inside the mounting groove 53. One end of the locking rod 52 is fixedly connected to the connecting block 54. A groove 55 is provided on the front of the connecting block 54. The groove 55 can be used to drive the connecting block 54 to slide inside the mounting groove 53, thereby causing the connecting block 54 to drive the locking rod 52 to separate from the positioning post 4, thereby unlocking the protective shell 2 and disassembling the protective shell 2. The limiting assembly 56 is disposed inside the groove 55. The limiting assembly 56 is used to limit the connecting block 54. Under the action of the limiting assembly 56, the stability of the connecting block 54 and the locking rod 52 when stationary can be ensured.

[0039] Example 2: Based on Example 1, the limiting component 56 includes a limiting block 561 and a limiting spring 562. The limiting block 561 is slidably engaged inside the mounting groove 53. The limiting spring 562 is disposed between the limiting block 561 and the connecting block 54. The limiting spring 562 can provide an elastic compressive force to the connecting block 54, thereby ensuring the stability of the connecting block 54 driving the locking rod 52 to engage with the positioning post 4. Furthermore, the elastic force of the limiting spring 562 acting on the connecting block 54 is sufficient to support the weight of the connecting block 54 and the locking rod 52.

[0040] Furthermore, the limiting assembly 56 also includes a guide rod 563 and a limiting rod 564. One end of the guide rod 563 is fixedly connected to the limiting block 561. The limiting spring 562 is slidably sleeved on the outside of the guide rod 563. A through hole matching the guide rod 563 is opened on one side of the connecting block 54. The outer wall of the guide rod 563 is slidably sleeved with the inner cavity of the through hole. The limiting rod 564 is fixedly connected to the inside of the mounting groove 53. A limiting hole is opened on the front of the limiting block 561. The outer wall of the limiting rod 564 is slidably engaged with the inner cavity of the limiting hole. The guide rod 563 can ensure the stability of the limit spring 562. When the locking rod 52 is slidably sleeved with the connecting hole on the fixing plate 51, the guide rod 563 can also limit the limit block 561. In conjunction with the limit rod 564, it can ensure the stability of the limit block 561 installed inside the mounting groove 53. When the locking rod 52 is separated from the connecting hole on the fixing plate 51, the connecting block 54, the locking rod 52 and the limit assembly 56 can be taken out from the mounting groove 53 for easy disassembly and maintenance.

[0041] Another objective of this invention is to provide an electrical switch that includes the aforementioned protective components.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
