[0029] In order to solve the problems of easy falling off between the fixed support and the gasket in the related art and high cost and low assembly efficiency, in the present application, the fixed part 122 is arranged on the gasket 12, and the assembly between the fixed support 11 and the gasket 12 is realized by the clamping and matching mode of the fixed part 122 and the fixed support 11, which can improve the mutual limiting between the fixed support 11 and the gasket 12, thereby reducing the probability of disengagement between the gasket 12 and the fixed support 11 during transportation, and reducing the required accuracy during assembly, improving the assembly efficiency and reducing the production cost.

[0030] The present application discloses an electrical device, which includes but is not limited to a safety device (such as a safety box), and the electrical device includes a support structure.

[0031] As shown in Figures 1 to 3 The support structure 10 can include a fixed support 11 and a gasket 12, wherein Figure 4 and Figure 5The fixing support 11 defines a fixing hole 111 which is arranged through the fixing support 11 in the axial direction. The fixing hole 111 can be a circular hole, a rectangular hole or a hole with other shapes, for example, the fixing hole 111 can be a waist-shaped hole, and the fixing hole 111 is arranged near the middle of the fixing support 11.

[0032] The washer 12 is arranged in the fixing hole 111, and the fixing portion 122 of the washer 12 is arranged in clamping cooperation with the fixing support 11 along the axial direction of the fixing hole 111. Further, the overall shape of the washer 12 is the same as or similar to the shape of the fixing hole 111, so that the washer 12 can be arranged in the fixing hole 111 and better cooperate with the fixing hole 111. For example, the fixing hole 111 is a waist-shaped hole, and the overall shape of the washer 12 is a waist-shaped structure (see Figure 6 and Figure 7 ).

[0033] As shown in Figures 1 to 3 , when the washer 12 and the fixing support 11 are assembled, the washer 12 can be arranged in the fixing hole 111 in the axial direction of the fixing hole 111. After the washer 12 is assembled, the fixing portion 122 of the washer 12 is arranged in clamping cooperation with the fixing support 11 in the axial direction, so as to limit the axial movement of the washer 12 in the fixing hole 111, thereby reducing the probability of the washer 12 being pulled out of the fixing hole 111. At the same time, the washer 12 and the fixing support 11 are assembled by clamping cooperation, and the clamping position is difficult to separate under the action of friction or external force, thereby improving the assembly stability between the washer 12 and the fixing support 11. Further, the assembly precision requirement is low, the assembly time is short, the assembly efficiency is improved, and the production cost is reduced.

[0034] As shown in Figure 6 and Figure 7 , the washer 12 can include a washer body 121 and a fixing portion 122 connected to the washer body 121.

[0035] Specifically, the washer 12 includes the washer body 121 and the fixing portion 122 connected to the washer body 121. The fixing portion 122 is arranged in clamping cooperation with the fixing support 11 along the axial direction of the fixing hole 111. In the state that the washer 12 is arranged in the fixing hole 111, the washer body 121 is arranged in the fixing hole 111, and the fixing portion 122 is arranged in clamping cooperation with the fixing support 11.

[0036] The washer 12 can be made of a metal material, which includes but is not limited to stainless steel, carbon steel, aluminum, brass or red copper.

[0037] In some embodiments, as shown in Figures 1 to 3As shown, the fixing portion 122 is arranged at both ends of the gasket body in the axial direction. Both ends of the gasket body 121 are provided with the fixing portion 122, and the fixing portions 122 at both ends cooperate to limit the displacement of the gasket 12 in both directions in the axial direction of the fixing hole 111. As shown in Figures 1 to 3 As shown, the fixing portion 122 at the upper end of the gasket body 121 is in clamping cooperation with the fixing support 11 to limit the downward movement of the gasket 12 in the axial direction. The fixing portion 122 at the lower end of the gasket body 121 is in clamping cooperation with the fixing support 11 to limit the movement of the gasket 12 in the axial direction.

[0038] In other embodiments, the fixing portion 122 can also be arranged at the middle or other positions of the gasket body 121 in the axial direction, which can be selected according to actual needs, and is not limited here.

[0039] In this embodiment, by arranging the fixing portion 122 at both ends of the gasket body 121 in the axial direction, the displacement of the gasket 12 can be limited by two limiting points, further improving the assembly stability between the gasket 12 and the fixing support 11. At the same time, the fixing portion 122 arranged at the end can facilitate the operation of the fixing portion 122 by the staff.

[0040] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 In some embodiments, the gasket body 121 defines a first notch 1211, and the fixing portion 122 is arranged at the first notch 1211. In the state of clamping cooperation between the fixing portion 122 and the fixing support 11, the fixing portion 122 and the side wall of the gasket body 121 are of a bent type.

[0041] As shown in Figure 6 and Figure 7 The end of the gasket body 121 defines a first notch 1211 recessed inward relative to the end face of the gasket body 121, and the fixing portion 122 is arranged in the first notch 1211.

[0042] The fixing portion 122 can be a trapezoidal structure, an elliptical structure, or other shape structures, as shown in Figure 6 and Figure 7 The fixing portion 122 can be a rectangular structure.

[0043] In the state that the gasket 12 and the fixing support 11 are not assembled, the end of the fixing portion 122 away from the bottom wall of the first notch 1211 can be flush with the end face of the gasket body 121, or can be lower than the end face of the gasket body 121, for example, the end of the fixing portion 122 away from the bottom wall of the first notch 1211 is flush with the end face of the gasket body 121.

[0044] Further, in the state that the gasket 12 and the fixing support 11 are not assembled, the fixing portion 122 is vertically arranged, when the gasket 12 and the fixing support 11 are assembled, the gasket 12 can be installed in the fixing hole 111 along the axial direction of the fixing hole 111, and after the gasket 12 is assembled in place, the fixing portion 122 of the gasket 12 is bent by a tool, so that the outer side of the fixing portion 122 is bent and abuts against the fixing support 11, thereby limiting the axial movement of the gasket 12 in the fixing hole 111.

[0045] Through the arrangement of the first notch 1211, the end of the fixing portion 122 away from the bottom wall of the first notch 1211 does not protrude from the end of the gasket body 121, thereby maintaining the overall flatness of the end of the gasket 12, and the fixing portion 122 is limited in position by being bent to abut against the fixing support 11, which is simple in structure and convenient to operate, and can further improve the assembly efficiency.

[0046] In some embodiments, as shown in Figures 1 to 3 , Figures 6 to 7 , the fixing portion 122 is provided in plurality, and the plurality of fixing portions 122 are distributed in the circumferential direction of the gasket body 121.

[0047] The fixing portion 122 can be three, four, seven or other numbers, for example, two fixing portions 122 are provided at one end of the gasket body 121, and the two fixing portions 122 are distributed in the circumferential direction.

[0048] The plurality of fixing portions 122 can be uniformly distributed in the circumferential direction of the gasket body 121, or can be unevenly distributed in the circumferential direction of the gasket body 121, for example, as shown in Figure 6 and Figure 7 , the two fixing portions 122 are uniformly distributed in the circumferential direction of the gasket body 121.

[0049] By providing the fixing portion 122 in plurality and distributing the plurality of fixing portions 122 in the circumferential direction of the gasket body 121, the number of clamping points between the gasket 12 and the fixing support 11 can be increased, thereby improving the limiting effect of the fixing portion 122 on the gasket body 121 and further improving the assembly stability between the gasket 12 and the fixing support 11.

[0050] In some embodiments, as shown in Figure 6 and Figure 7 , the thickness of the fixing portion 122 is less than the thickness of the gasket body 121.

[0051] As shown in Figure 6 and Figure 7 , the thickness of the fixing portion 122 can be half of the thickness of the gasket body 121, or 1 / 3 of the thickness of the gasket body 121, or other values.

[0052] Since the fixed portion 122 needs to be bent by a tool during assembly, the greater the thickness of the fixed portion 122 in the same axial height of the fixed portion 122, the more difficult it is to bend. Therefore, the thickness of the fixed portion 122 is set to be smaller than the thickness of the gasket body 121, which can reduce the probability of bending the gasket body 121 during bending of the fixed portion 122, facilitate bending of the fixed portion 122, and improve assembly efficiency.

[0053] In some embodiments, as shown in Figs. 1 and 2, the gasket body 121 has a first notch 1211 extending through the gasket body 121 in the axial direction. Figure 6 and Figure 7 As shown in Figs. 1 and 2, the gasket body 121 has a second notch 1212 extending through the gasket body 121 in the axial direction.

[0054] The second notch 1212 cuts the gasket body 121, i.e., the gasket body 121 can be understood as a rectangular structure rolled into a waist-shaped structure, and the ends of the gasket body 121 are spaced apart in the circumferential direction, and the gap between the two ends forms the second notch 1212.

[0055] Through the above-mentioned setting of the second notch 1212, the size of the gasket 12 can be adjusted when the gasket 12 is installed, so that the gasket 12 can better fit the inner wall of the fixing hole 111, thereby improving the assembly stability between the gasket 12 and the fixing bracket 11.

[0056] In some embodiments, the second notch 1212 is provided with a protrusion 1214 protruding outward on a first side in the circumferential direction of the gasket body 121, and the second notch 1212 is provided with a limiting groove 1213 recessed inward on a second side in the circumferential direction of the gasket body 121, and at least part of the protrusion 1214 is located in the limiting groove 1213.

[0057] The first end of the gasket body 121 in the circumferential direction is the first side of the second notch 1212 in the circumferential direction of the gasket body 121, and the second end of the gasket body 121 in the circumferential direction is the second side of the second notch 1212 in the circumferential direction of the gasket body 121, i.e., the first end of the gasket body 121 in the circumferential direction is provided with a protrusion 1214 protruding towards the second end of the gasket body 121 in the circumferential direction, and the second end of the gasket body 121 in the circumferential direction is provided with a limiting groove 1213 recessed in a direction away from the first end of the gasket body 121 in the circumferential direction.

[0058] The protrusion 1214 can be partially located in the limiting groove 1213 or completely located in the limiting groove 1213. For example, the protrusion 1214 is completely located in the limiting groove 1213. Since the protrusion 1214 and the limiting groove 1213 are circumferentially arranged, when the protrusion 1214 is located in the limiting groove 1213, the protrusion 1214 can abut against the side wall of the limiting groove 1213. When the washer body 121 is axially deformed under the action of an external force, the protrusion 1214 abuts against the side wall of the limiting groove 1213 in the axial direction, thereby preventing the washer body 121 from being axially deformed.

[0059] Through the arrangement of the protrusion 1214 and the limiting groove 1213, the axial deformation of the washer body 121 can be reduced, thereby further improving the assembly stability between the washer 12 and the fixing support 11.

[0060] In some embodiments, the width of the protrusion 1214 gradually decreases from one end of the protrusion 1214 facing the limiting groove 1213 to the other end of the protrusion 1214 away from the limiting groove 1213 in the axial direction, and the width of the limiting groove 1213 gradually decreases from one end of the limiting groove 1213 away from the protrusion 1214 to the other end of the limiting groove 1213 facing the protrusion 1214 in the axial direction.

[0061] Preferably, the protrusion 1214 and the limiting groove 1213 are both in trapezoidal structures. Specifically, the protrusion 1214 is in a trapezoidal structure as a whole, and the limiting groove 1213 is also in a trapezoidal structure as a whole. The one end of the protrusion 1214 facing the limiting groove 1213 is the upper base of the trapezoidal structure, and the other end of the protrusion 1214 away from the limiting groove 1213 is the lower base of the trapezoidal structure. The one end of the limiting groove 1213 facing the protrusion 1214 is the lower base of the trapezoidal structure, and the other end of the limiting groove 1213 away from the protrusion 1214 is the upper base of the trapezoidal structure.

[0062] During the process of arranging the protrusion 1214 in the limiting groove 1213, the upper base of the protrusion 1214 is moved circumferentially first, enters the limiting groove 1213 after passing through the lower base of the limiting groove 1213, and then gradually moves the whole protrusion 1214 into the limiting groove 1213.

[0063] It can be understood that, if the width of the protrusion 1214 is consistent and the width of the limiting groove 1213 is consistent, the corners of the protrusion 1214 can be stuck with the corners of the limiting groove 1213 during the process of arranging the protrusion 1214 in the limiting groove 1213, which reduces the processing efficiency. Therefore, arranging the protrusion 1214 and the limiting groove 1213 in trapezoidal structures can facilitate the processing of the washer body 121, reduce the probability of the protrusion 1214 being stuck with the limiting groove 1213, and improve the processing efficiency of the washer 12.

[0064] For example, Figures 1 to 5As shown in the drawings, in some embodiments, the fixing support 11 is provided with a groove 112 on the end face along the axial direction of the fixing hole 111, and the fixing portion 122 is in clamping fit with the bottom wall of the groove 112.

[0065] As shown in the drawings, in some embodiments, the fixing support 11 is provided with a groove 112 on the end face along the axial direction of the fixing hole 111, and the fixing portion 122 is in clamping fit with the bottom wall of the groove 112. Figure 3

[0066] Through the above-mentioned arrangement of the groove 112, the fixing portion 122 can be bent and located in the groove 112, so as not to protrude from the end face of the fixing support 11, so as to keep the flatness of the gasket 12 and the end face of the fixing support 11 after assembly, facilitate the subsequent installation of the fixing support 11 and the gasket 12 with other components, and reduce the overall space occupied by the fixing support 11 and the gasket 12.

[0067] As shown in the drawings, in some embodiments, the fixing portion 122 is located on the side close to the fixing support 11 of the bottom wall of the first gap 1211. Figures 1 to 3 Figures 6 to 7 As shown in the drawings, in some embodiments, the fixing portion 122 is located on the side close to the fixing support 11 of the bottom wall of the first gap 1211.

[0068] As shown in the drawings, in some embodiments, the fixing portion 122 is located on the side close to the fixing support 11 of the bottom wall of the first gap 1211.

[0069] As shown in the drawings, in some embodiments, the fixing portion 122 is located on the side close to the fixing support 11 of the bottom wall of the first gap 1211.

[0070] It can be understood that the above embodiments only express the preferred embodiments of the present application, which are described in detail and specifically, but cannot be understood as the limitation of the patent scope of the present application; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application should belong to the scope of the claims of the present application.​​
