DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] The utility model is a speed regulating switch which is easy to assemble. Figures 1 to 4 As shown, it includes a speed regulating switch functional component 1 and a frame 2 for connecting to a bottom box. The left and right sides of the frame 2 are respectively formed with bottom box connection holes 201. The switch mounting screw passes through the above bottom box connection holes 201 and is screwed to the bottom box embedded in the wall, so that the speed regulating switch can be fixedly installed on the wall. The frame 2 can be formed by stamping. Figure 5 As shown, the speed regulating switch functional component 1 includes a speed regulating component 11 and a switch component 12. Figure 5 As shown, the speed regulating switch functional assembly 1 comprises a rear shell 13 and a cover seat 14, wherein the cover seat 14 is disposed on the front side of the rear shell 13. Specifically, buckle ears are formed around the cover seat 14, and the buckle ears are buckled with the convex buckle blocks on the front outer side of the rear shell 13. Fig.10 As shown, the rear housing 13 is formed with a circuit board accommodating cavity 131 and a switch accommodating cavity 132, the circuit board accommodating cavity 131 and the switch accommodating cavity 132 are distributed in the left and right directions, and a partition 133 is provided between the circuit board accommodating cavity 131 and the switch accommodating cavity 132. Fig. 9 As shown, the speed regulating assembly 11 includes an encoder 111 and a circuit board 112. The encoder 111 is welded and mounted on the front side of the circuit board 112. The circuit board 112 is rectangular. Figure 8 As shown, the circuit board 112 is adapted to be disposed in the circuit board accommodating cavity 131. In other words, the circuit board 112 is positioned by the inner wall of the circuit board accommodating cavity 131 in the up-down and left-right directions, which can prevent the circuit board 112 and the encoder 111 from loosening. The switch assembly 12 is disposed in the switch accommodating cavity 132. Figure 6 and Figure 7As shown, the encoder 111 is provided with a rotating shaft 1111, and the rotating shaft 1111 is arranged to pass forward through the cover seat 14. Specifically, the cover seat 14 is provided with a rotation support hole, and the rotating shaft 1111 is adapted to be rotatably connected to the above-mentioned rotation support hole. The above-mentioned rotation support hole can support the rotating shaft 1111 when the rotating shaft 1111 is subjected to radial impact, thereby preventing the encoder 111 from being easily damaged. Figure 2 Combination Figure 4 As shown, the cover seat 14 is adapted to be installed in the frame 2. Figure 7 and Fig. 9 As shown, the switch assembly 12 includes a drive member 121, such as Fig.11 As shown, the driving member 121 is formed with a swing arm portion 1212, and the swing arm portion 1212 is arranged on the front side of the cover seat 14, but the front side of the cover seat 14 is formed with a groove structure, and the swing arm portion 1212 is sunk into the above-mentioned groove structure. The front end of the middle part of the swing arm portion 1212 in the up-down direction is formed with a swing arm hinge convex head, and the swing arm portion 1212 is hinged with the cover seat 14 through the above-mentioned swing arm hinge convex head, as shown in FIG. Fig.11 As shown, the driving member 121 is formed with a lever portion 1211, the front end of the lever portion 1211 is connected to the middle portion of the swing arm portion 1212 in the up and down direction, the lever portion 1211 passes through the cover seat 14, the lever portion 1211 is a hollow structure, a compression spring is arranged in the lever portion 1211, the switch assembly 12 includes a switch swing piece 122, the rear end of the compression spring is connected to the switch swing piece 122, as shown in FIG. Fig.10 As shown, a swing fulcrum groove 1321 is formed at the bottom of the switch accommodating cavity 132, and the rear end of the switch swing piece 122 is arranged in the swing fulcrum groove 1321, so that the rear end of the lever part 1211 swings up and down to switch the switch state; since the working principle of the switch assembly 12 belongs to the prior art, examples can refer to the Chinese utility model patent publication number CN221466483U "A swing piece contact structure of a switch and a switch with the structure", and the working principle of the switch assembly 12 is not the focus of the utility model, so it will not be described in detail.

[0026] like Fig.11 As shown, an arcuate recess 1213 is formed on one side of the middle portion of the swing arm portion 1212 in the up-down direction and relatively away from the partition plate 133. That is, the arcuate recess 1213 is arranged facing away from the encoder 111, so the swing arm portion 1212 is in an arcuate shape due to the arcuate recess 1213, as shown in FIG. Figure 5 As shown, the cover seat 14 is provided with a notch 140 for accommodating the switch mounting screws, and the arcuate recess 1213 is correspondingly arranged on the inner side of the notch 140. As described above, the switch mounting screws are used to pass through the bottom box connection holes 201 of the frame 2. Figure 1 and Figure 3As shown, the speed regulating switch of the utility model further includes a swing-arranged switch button 31, and the switch button 31 is arranged on the front side of the swing arm portion 1212, as shown in FIG. Figure 7 As shown, the upper and lower ends of the swing arm portion 1212 are respectively connected to the rear side of the switch button 31. Specifically, a hinge fork is formed on the rear side of the middle part of the switch button 31 in the up-down direction. Fig.12 As shown, the panel 3 is formed with a hinge shaft 301, and the above-mentioned hinge fork connects the hinge shaft 301, so that the upper and lower ends of the panel 3 can swing back and forth slightly, so when the switch button 31 is pressed, the upper end of the switch button 31 or the lower end of the switch button 31 pushes the swing arm part 1212 backward accordingly, so that the lever part 1211 swings to realize the switch switching function.

[0027] As mentioned above and Figure 2 As shown, the speed regulating switch functional component 1 of the utility model is provided with a rear shell 13 to accommodate the speed regulating component 11 and the switch component 12, so that the speed regulating function and the lamp switch function are integrated into one functional component (i.e. Figure 3 and Figure 4 The speed regulating switch functional assembly 1 shown in the figure can reduce the types and quantity of parts of the speed regulating switch. In the final assembly process, the speed regulating assembly 11 and the switch assembly 12 can be installed and connected to the frame 2 in one assembly. Therefore, compared with the prior art, the utility model is conducive to making the speed regulating switch assembly simple. By providing the notch 140 and the arched recess 1213, as shown in FIG. Figure 2 As shown, the cover 14 is prevented from interfering with the switch mounting screws passing through the frame 2, and, as shown Figure 3 and Figure 5 As shown, the upper and lower ends of the swing arm portion 1212 can be relatively close to the edge, that is, the upper and lower ends of the swing arm portion 1212 can be close to the edge of the shape of the speed control switch in the left and right directions, so that the upper and lower ends of the switch button 31 set close to the edge can well transmit the thrust to the swing arm portion 1212, that is, to avoid the situation where the switch does not work when the user presses the switch button 31 backwards close to the outer edge (in the left and right directions) of the speed control switch. Of course, it can also be understood that by providing the notch portion 140 and the arched recess 1213, the speed control switch functional component 1 can avoid the above-mentioned switch mounting screws and can make the switch button 31 as close to the edge as possible (in the left and right directions), as shown in FIG. Figure 1 As shown, the switch button 31 can have a larger pressing operation range, and the speed regulating assembly 11 can have sufficient installation position and speed regulating operation space. The speed regulating assembly 11 and the switch assembly 12 are insulated and separated by the partition plate 133, which is beneficial to the safety of electricity use.

[0028] Furthermore, if Figure 1 , Figure 3 and Figure 4As shown, the speed regulating switch of the utility model further includes a panel 3, the panel 3 is covered on the front side of the frame 2, and the switch button 31 is located on the front side of the panel 3, as shown in FIG. Fig.12 As shown, a through hole 302 is formed on the panel 3. Figure 3 As shown, the rotating shaft 1111 is arranged through the through hole 302, as shown in FIG. Fig.12 As shown, a card 303 is formed on the rear side of the panel 3, and the card 303 is arranged correspondingly near the through hole 302, as shown in FIG. Figure 7 As shown, a snap-on bridge shaft 1401 is formed on the cover seat 14. Specifically, a rectangular hole is formed on the cover seat 14. The snap-on bridge shaft 1401 connects the opposite sides of the rectangular hole, so that the snap-on bridge shaft 1401 is in the shape of a bridge. The snap-on bridge shaft 1401 is located between the rotating shaft 1111 and the swing arm portion 1212. The card 303 is snap-connected with the snap-on bridge shaft 1401. That is, the card 303 is inserted into the rectangular hole, and the snap-on port of the card 303 is connected to the snap-on bridge shaft 1401, so that the card 303 is positioned in the radial direction of the snap-on bridge shaft 1401. Since the snap-on bridge shaft 1401 is located between the rotating shaft 1111 and the swing arm portion 1212, as shown in FIG. Figure 1 As shown, the middle portion of the panel 3 can be prevented from arching forward, and the edges of the panel 3 can correspond to the edges of the buckled frame 2 respectively.

[0029] Furthermore, if Figure 5 As shown, a positioning protrusion 141 and a buckle hook 142 are formed on the outer side of the cover seat 14. The positioning protrusion 141 is located at the front side of the buckle hook 142. Figure 3 and Figure 4 As shown, the inner edge of the frame 2 is formed with a rear folded edge 21, that is, the rear folded edge 21 is folded backwards, as shown in FIG. Figure 2 As shown, the rear folded edge 21 is located on the outer side of the cover seat 14, and the rear folded edge 21 is adapted to be arranged between the positioning protrusion 141 and the hook 142 in the front-to-back direction. Specifically, the cover seat 14 is formed with a slot at the front end position of the rear folded edge 21. During the assembly process, the speed control switch functional component 1 is inserted into the frame 2 from front to back, and then the hook 142 is elastically squeezed inward by the relative compression of the rear folded edge 21. At the same time, the positioning protrusion 141 is also inserted into the corresponding above-mentioned slot from front to back. When the positioning protrusion 141 reaches the bottom of the above-mentioned slot, the hook 142 also just passes over the rear folded edge 21 backward, and the hook 142 elastically resets and swings outward, so that the hook 142 is buckled with the rear end edge of the rear folded edge 21. Specifically, two hooks 142 are respectively provided at the upper and lower ends of the cover seat 14; it can be seen from the above that the assembly of the speed control switch functional component 1 and the frame 2 only requires a single insertion operation, which is conducive to the easy assembly of the speed control switch.

[0030] Furthermore, if Figure 1As shown, a knob 4 is mounted on the rotating shaft 1111. Specifically, an elastic inner tooth clamp is formed on the rear side of the knob 4, and the rotating shaft 1111 is inserted into the above-mentioned elastic inner tooth clamp. The knob 4 is located on the front side of the panel 3, and the switch button 31 is located on the right side of the knob 4. Through the above-mentioned arrangement, when the switch button 31 is pressed by the thumb or index finger of the right hand, the right hand is not easy to touch the knob 4. When the knob 4 is pinched with the right hand, since the forward protruding height of the switch button 31 is small, the right hand is not easily hindered by the switch button 31. Therefore, the speed control switch of the utility model is suitable for users with right-handed habits.

[0031] Furthermore, if Figure 2 and Fig.10 As shown, heat dissipation grooves 1311 are formed around the rear of the circuit board accommodating cavity 131 , and the heat generated by the speed regulating component 11 during operation can be dissipated outward through the heat dissipation grooves 1311 , thus facilitating heat dissipation of the speed regulating component 11 .
