[0044] Embodiment 1

[0045] This embodiment provides a reset switch. As shown in the attached Figures 1-7 figure, it includes:

[0046] A body 11, the body 11 is provided with a receiving cavity 111, and here the receiving cavity 111 is a closed cavity.

[0047] A common terminal component 12, the common terminal component 12 is accommodated in the receiving cavity 111. The common terminal component 12 specifically means common, that is, in the electrical connection process, the remaining shrapnel components cooperate with the common terminal component 12 to form a part of the electrical circuit. Here, a part of the common terminal component 12 is located in the receiving cavity 111, and a part of the common terminal component 12 extends through the receiving cavity 111 to the outside of the body 11. Here, the extending direction of the common terminal component 12 can be axially vertically downward, or horizontally outward. In this embodiment, taking the common terminal component 12 extending axially vertically downward as an example.

[0048] A shrapnel component 13, the shrapnel component 13 is accommodated in the receiving cavity 111. When the shrapnel component 13 is in contact connection with the common terminal component 12, the shrapnel component 13 and the common terminal component 12 form an electrical connection effect, and the two are connected to the circuit. Here, the number of the shrapnel components 13 can be one group, two groups, three groups, or even more. The number of the shrapnel components 13 is specifically determined according to the size of the receiving cavity 111. For example, when the number of the shrapnel components 13 is two groups, when the rotating handle rotates, at this time, the two groups of shrapnel components 13 can simultaneously form an electrical connection with the common terminal component 12, or the two groups of shrapnel components 13 form one group connected and one group disconnected, or can also form the effect that both groups are disconnected. Here, it can be adjusted according to actual needs. In this embodiment, taking the number of the shrapnel components 13 as two groups as an example. A part of the shrapnel component 13 is located in the receiving cavity 111, and the remaining part of the shrapnel component 13 extends outside the receiving cavity 111. Here, the shrapnel component 13 is the same as the common terminal component 12 and also extends axially vertically downward. The part of the shrapnel component 13 located in the receiving cavity 111 is elastically arranged, and its end is used to cooperate with the common terminal component 12. Here, a contact is provided at the end, and the middle part is used to cooperate with the rotating handle. When the rotating handle rotates, it will drive the shrapnel component 13 to move, realizing the connection or disconnection between the end and the common terminal component 12. This is the prior art, so it will not be described in detail in this embodiment.

[0049] The rotating handle 14 is received in the receiving cavity 111. A part of the rotating handle 14 is located inside the receiving cavity 111, and the remaining part of the rotating handle 14 extends vertically upward in the axial direction. The part of the rotating handle 14 located outside is used to cooperate with the operator to form a rotating effect. The lower end of the rotating handle 14 is provided with gear slots 141 distributed in a circumferential array, and the rotating handle 14 rotates relative to the body 11. In this embodiment, it should also be noted that the rotating handle 14 is further provided with a boss for cooperating with the elastic piece assembly 13. Here, the boss is a prior art and will not be described in detail either.

[0050] The reset assembly 15 is received in the receiving cavity 111. The reset assembly 15 cooperates with one end of the rotating handle 14 close to the top surface of the body 11. Here, the reset assembly 15 is located in the upper region of the receiving cavity 111. The reset assembly 15 gives a restoring force to the rotating handle 14. When the rotating handle 14 rotates, the reset assembly 15 will deform. When the force applied to the rotating handle 14 is withdrawn, at this time, the reset assembly 15 will drive the rotating handle 14 to rotate and return to the initial state.

[0051] The gear component is received in the receiving cavity 111. Here, the entire gear component is located in the lower region of the receiving cavity 111. Specifically, the entire receiving cavity 111 is divided into three regions: upper, middle, and lower. The upper region is used to cooperate with the reset assembly 15, the middle region is used to cooperate with the elastic piece assembly 13, and the lower region is used to cooperate with the gear component. Here, the cooperation is specifically with the rotating handle 14. The gear component includes a bracket 16 and an elastic structure. The bracket 16 is located above the bottom surface of the receiving cavity 111. The bracket 16 is provided with a groove 161, and the groove 161 opens toward the side of the gear slot 141. The elastic structure is received in the groove 161. A part of the elastic structure is located inside the groove 161, and the part of the elastic structure extending outside the groove 161 cooperates with the gear slot 141, that is, one end of the elastic structure extends outside the groove 161 to cooperate with the gear slot 141. When the rotating handle 14 rotates, the position where the elastic structure abuts against the two gear slots 141 will form a contraction effect. When passing this position, the elastic structure will release energy and abut against the next gear slot 141. With this structural arrangement, the reset assembly 15 and the gear component are arranged independently. The gear component is located above the bottom surface of the receiving cavity 111, and the overall fixation of the gear component is achieved through the bracket 16. Compared with the prior art where the gear component is connected to the rotating handle 14 or the gear component is connected to the base cover, this structure is independently installed, making the installation more convenient, thus improving the efficiency. At the same time, it also gives the technical personnel in this field the expansion trend of this structure, spreads the research and development direction of the R & D personnel, and improves the innovation ability.

[0052] Specifically, the bracket 16 is fixedly connected to the bottom surface of the accommodation cavity 111. The connection and fixation method between the bracket 16 and the bottom surface of the accommodation cavity 111 can be a fixed fit, an interference fit, a bolt fixation, a snap fixation, etc. Alternatively, the bracket 16 is fixedly connected to the side wall of the accommodation cavity 111. Here, the connection and fixation method can be an interference fit, a fixed fit, a bolt fixation, a snap fixation, etc.

[0053] Specifically, as shown in Figures 3-5 Figures 6 and 7, one of the bottom surface of the bracket 16 and the accommodation cavity 111 is provided with a fixing post 17, and the other of the bottom surface of the bracket 16 and the accommodation cavity 111 is provided with a fixing hole 18 that cooperates with the fixing post 17. When the bracket 16 is provided with the fixing post 17, the bottom surface of the accommodation cavity 111 is provided with the fixing hole 18; conversely, when the bracket 16 is provided with the fixing hole 18, the bottom surface of the accommodation cavity 111 is provided with the fixing post 17. In this embodiment, taking the bracket 16 being provided with the fixing hole 18 as an example, the bottom surface of the accommodation cavity 111 is provided with a corresponding fixing post 17. Here, the number of the fixing holes 18 and the fixing posts 17 can be adjusted according to actual needs. In this embodiment, two groups are taken as an example. Further, the fixing post 17 can be a cylinder, a prism, or a frustum of a pyramid. In this embodiment, the cross-section of the fixing post 17 is a runway shape. Since the bracket 16 is located above the bottom surface of the accommodation cavity 111, under the action of gravity, the bracket 16 fits with the bottom surface of the accommodation cavity 111, and horizontal limit fixation is formed through the cooperation of the fixing post 17 and the fixing hole 18. It should be noted here that when other parts such as the rotating handle 14 are fixed, limit fixation of the bracket 16 in the axial vertical direction is also formed, and at this time, the bracket 16 will not shake. In addition, when the bracket 16 is fixed, snap protrusions can also be provided on the side wall of the accommodation cavity 111 to form a limitation in the axial vertical direction.

[0054] Specifically, as shown in Figure 2As shown in the figure, the elastic structure includes a sleeve 19 and an elastic member 20. The sleeve 19 is provided with a cavity 191. At this time, one end of the sleeve 19 is open, and the other end of the sleeve 19 is closed. The closed end cooperates with the gear position groove 141 to form the switching effect between gear positions. The elastic member 20 is accommodated in the cavity 191, and the other end of the elastic member 20 abuts against the bracket 16. At this time, the groove 161 is only open at one end. Or, the other end of the elastic member 20 abuts against the side wall of the accommodation cavity 111. At this time, the groove 161 is open at both ends, and the elastic member 20 passes through the cavity 191, the groove 161 and abuts against the side wall of the accommodation cavity 111. The cooperation between the sleeve 19 and the elastic member 20 forms the effect of the gear position. Here, the sleeve 19 cooperates with the gear position groove 141, and the other end of the elastic member 20 can abut against the bracket 16, and the other end of the elastic member 20 can also abut against the side wall of the accommodation cavity 111, which can be adjusted by those skilled in the art according to actual needs. In addition, in order to improve the installation convenience of the elastic member 20, the groove 161 can also be provided with a lower opening, that is, the groove 161 is located on the bottom surface of the bracket 16, forming openings in three directions: the left and right ends and the lower part. At this time, the elastic member 20 is located above the bottom surface of the accommodation cavity 111. In this embodiment, the elastic member 20 can be a spring. In addition, the elastic structure can also be a combination of a spring and a steel ball.

[0055] Specifically, the number of elastic components is two, that is, two grooves 161 are provided on the bracket 16, and the two elastic components are symmetrically arranged. In addition, the number of elastic components can be adjusted according to actual needs, and can be one or more.

[0056] Specifically, as shown in the attached Figure 7 figure, the bracket 16 is provided with a first strengthening portion 162, and the first strengthening portion 162 is located above the groove 161. The setting of the first strengthening portion 162 improves the strength of the area where the groove 161 is located. In this embodiment, since the number of grooves 161 is two, the number of the first strengthening portions 162 is also two.

[0057] Specifically, as shown in the attached Figure 7 figure, the bracket 16 is provided with a second strengthening portion 163, and the fixing hole 18 is arranged on the second strengthening portion 163; or, the fixing post 17 is arranged on the second strengthening portion 163. In this embodiment, taking the fixing hole 18 being arranged on the second strengthening portion 163 as an example, the second strengthening portion 163 also increases the strength of the bracket 16.

[0058] Specifically, the rotating handle 14 is provided with an arc-shaped protrusion 142. The arc-shaped protrusion 142 is located at the upper end of the part of the rotating handle 14 in the receiving cavity 111, that is, the arc-shaped protrusion 142 extends vertically upward toward the top surface of the receiving cavity 111. The reset assembly 15 is sleeved on the rotating handle 14. One end of the reset assembly 15 abuts against one end of the arc-shaped protrusion 142, and the other end of the reset assembly 15 abuts against the side wall of the receiving cavity 111. The reset assembly 15 cooperates with the rotating handle 14 to form a restoring force for rotating the rotating handle 14. In this embodiment, the reset assembly 15 is specifically a torsion spring.

[0059] Specifically, the receiving cavity 111 is provided with a limiting protrusion 21. The limiting protrusion 21 is located on the movement track of the arc-shaped protrusion 142. The limiting protrusion 21 forms a limiting effect to prevent excessive rotation.

[0060] Specifically, as shown in the attached Figure 2 figure, one of the bottom surfaces of the rotating handle 14 and the receiving cavity 111 is provided with a connection hole 22, and the other of the bottom surfaces of the rotating handle 14 and the receiving cavity 111 is provided with a connection post 23 that cooperates with the connection hole 22. The connection post 23 rotates relative to the connection hole 22. In this embodiment, the bottom surface of the receiving cavity 111 is provided with the connection post 23, and the bottom surface of the rotating handle 14 is provided with the connection hole 22, so that the rotating handle 14 is sleeved on the connection post 23.

[0061] Specifically, as shown in the attached Figures 1-2 figure, the body 11 includes a base 24 and a base cover 25. The base 24 and the base cover 25 cooperate to form the receiving cavity 111. The base 24 and the base cover 25 can be detachably connected, such as bolt connection or snap connection. In this embodiment, the rotating handle 14 extends through the base cover 25 to the outside, and the common end assembly 12 and the elastic sheet assembly 13 extend through the base 24 to the outside. Here, the common end assembly 12, the elastic sheet assembly 13 and the base 24 can be integrally injection-molded. The limiting protrusion 21 is arranged on the side of the base cover 25 facing the base 24. The base 24 is provided with structures such as a connection post 23 and a fixing post 17.
