As the sliding member 31 is driven by the driving mechanism 2, the limiting portion 33 slides along the guide groove 34 to drive the linkage member 32 to move in a direction perpendicular to the support surface 10, that is, to move in a direction close to or away from the support surface 10. The formation of the limiting portion 33 and the guide groove 34 has the advantages of simple processing and low cost.

[0044] Combination Figure 1-10 A first embodiment of a mechanical emergency start contactor device is provided.

[0045] like Figure 1 , 2 As shown, the mechanical emergency starting contactor device includes a supporting structure 1, a driving mechanism 2, a steering mechanism 3 and a transmission mechanism 4, wherein the supporting structure 1 is used to provide an assembly position, a contactor 6 and a transmission mechanism 4 are arranged on a supporting surface 10 of the supporting structure 1, the driving mechanism 2 and the steering mechanism 3 are respectively arranged on the supporting structure 1, wherein the driving mechanism 2 is rotatably assembled and connected with an operating member 5, the steering mechanism 3 is linked and connected between the driving mechanism 2 and the transmission mechanism 4, the transmission mechanism 4 is linked with the contact support of the contactor 6, and the opening and closing of the contactor 6 can be manually operated through the operating member 5.

[0047] Among them, Figure 5 , 6 As shown, the sliding member 31 is provided with a guide groove 34, the guide groove 34 is extended in a direction close to the driving mechanism 2, and the groove line of the guide groove 34 is to the support surface 10 (see Figure 8 ) are not completely equal. In the present embodiment, the distances from both ends of the guide groove 34 to the support surface 10 are not equal. The linkage member 32 is provided with a limit portion 33 which is slidably matched with the guide groove 34. When the sliding member 31 slides in a direction parallel to the support surface 10, the limit portion 33 slides along the guide groove 34. At the same time, the limit portion 33 also moves in a direction close to or away from the support surface 10, thereby driving the linkage member 32 and the transmission plate 41 to move in a direction perpendicular to the support surface 10.

[0048] Combination Figure 2 and 5 -9 provides a specific structure of a steering mechanism 3.

[0049] like Figure 2 , 5As shown in Figure 6, the steering mechanism 3 includes a sliding member 31 and a linkage member 32, wherein the sliding member 31 includes a connecting plate 311. The connecting plate 311 in the figure is a rectangular plate-shaped structure as a whole. A pair of connecting walls 312 arranged at intervals are connected to both sides of the connecting plate 311. The pair of connecting walls 312 and the connecting plate 311 together form a U-shaped cavity. When the sliding member 31 is set on the support structure 1, the U-shaped cavity provides a movement space for the linkage plate 321 to prevent the linkage member 32 from being disturbed by the outside; the edge of each connecting wall 312 is bent outward and extended to form a sliding portion 314. Correspondingly, a slide rail that cooperates with the sliding portion 314 can be opened on the support structure 1, and the sliding portion 314 slides with the support structure 1. Dynamic cooperation, of course, it is also possible not to set the sliding part 314, and the side of the connecting plate 311 facing away from the connecting wall 312 can be slidably cooperated with the support structure 1; each connecting wall 312 is provided with a guide groove 34. In the present embodiment, each connecting wall 312 is provided with two guide grooves 34, and the two guide grooves 34 are arranged at intervals, and the guide grooves 34 located on the two connecting walls 312 correspond to each other, so that a symmetrical structure can be formed, which is beneficial to improve the cooperation stability between the guide linkage 32 and the sliding member 31; a driving groove 313 is extended outward from one end of the connecting plate 311, and the driving groove 313 is connected to the driving of the driving mechanism 2, thereby driving the sliding member 31 to move in the direction of approaching or away from the driving mechanism 2.

[0050] In this embodiment, the guide groove 34 is preferably a strip groove, and the inner diameter of the strip groove is approximately equal to the outer diameter of the limiting portion 33, which is conducive to improving the degree of matching. Figure 6 As shown, the guide groove 34 includes a first straight section 341 and a second straight section 342. The distance from the first straight section 341 to the support surface 10 is greater than the distance from the second straight section 342 to the support surface 10. An inclined transition section 343 is connected between the first straight section 341 and the second straight section 342, so that the guide groove 34 is Z-shaped as a whole. In this embodiment, the first straight section 341 and the second straight section 342 are respectively parallel to the support surface 10. In the same guide groove 34, the first straight section 341 is closer to the driving groove 313 than the second straight section 342.

[0051] in addition, Figure 6 The lengths of the first straight section 341 and the second straight section 342 are smaller than the transition section 343. According to actual needs, the lengths of the first straight section 341, the second straight section 342 and the transition section 343 can be appropriately adjusted, and the spacing between the first straight section 341 and the second straight section 342 can also be adjusted, thereby adjusting the inclination and length of the transition section 343, thereby adjusting the moving stroke of the limit portion 33, and further adjusting the moving stroke of the transmission mechanism 4.

[0052] Of course, the guide groove 34 is not limited to a strip groove, that is, the guide groove 34 can also be a groove with a diameter larger than the limiting portion 33, but the contact surface of the guide groove 34 used to cooperate with the limiting portion 33 is preferably higher on one side and lower on the other side, and the higher part and the lower part are connected by an inclined surface.

[0053] like Figure 7 As shown, the linkage member 32 includes a linkage plate 321, the size of the linkage plate 321 is smaller than the cavity of the sliding member 31, and the two ends of the linkage plate 321 are bent toward the same side to form a linkage portion 322. Preferably, the linkage portion 322 slides and limits with the support structure 1 to ensure that the linkage member 32 can move in a direction perpendicular to the support surface 10, but will not be driven by the sliding member 31 to move toward or away from the driving mechanism 2. The edge of each linkage portion 322 extends outward and bends to form a hook 324, and each hook 324 is used to connect with the slot 411 of the transmission mechanism 4, which is convenient for assembly and ensures the connection stability. The hook 324 used to connect with the transmission mechanism 4 protrudes from the middle edge of the linkage plate 321 to form a limiting portion 33, wherein the limiting portion 33 can be formed by the linkage portion 322 protruding as a whole, or it can be a separately assembled limiting portion 33.

[0054] In this embodiment, the limiting portion 33 is preferably a separately assembled structure to facilitate the assembly of the linkage member 32 and the sliding member 31. Figure 7 As shown, the edges of both sides of the middle part of the connecting plate 311 are bent and extended to the same side to form a pair of convex edges 323, and a pair of through holes are provided on the pair of convex edges 323. A shaft rod is limitedly installed in each pair of through holes, and the end of the shaft rod serves as a limit part 33 and slides with the guide groove 34. In addition, an anti-dropping piece can be sleeved on the shaft rod, or an anti-dropping boss can be formed by protruding from the circumferential side wall of the shaft rod, so as to prevent the shaft rod from falling out of the through hole.

[0055] When the limiting portion 33 is located in the first straight section 341, the linkage member 32 is farthest from the support surface 10; when the limiting portion 33 is located in the second straight section 342, the linkage member 32 is closest to the support surface 10; when the limiting portion 33 moves in the transition section 343, the linkage member 32 moves in a direction perpendicular to the support surface 10 and drives the transmission mechanism 2 to move in a straight line, that is, when the limiting portion 33 moves from the first straight section 341 into the transition section 343, the linkage member 32 moves toward the support surface 10; when the limiting portion 33 moves from the second straight section 342 into the transition section 343, the linkage member 32 moves away from the support surface 10.

[0056] Combination Figure 2-4A driving mechanism 2 applied to the present embodiment is provided, the driving mechanism 2 comprises a driving wheel 21 and an energy storage assembly 22, an indicating portion 211 and a driving portion 212 are respectively provided at opposite ends of the driving wheel 21, a protruding circular boss is provided in the middle of one end of the driving wheel 21, the outer diameter of the circular boss is smaller than the outer diameter of the driving wheel 21, a driving hole 214 is provided in the middle of the circular boss, the operating member 5 is connected to the driving wheel 21 through the driving hole 214, a boss as an indicating portion 211 is provided on the circumferential side wall of the circular boss, and a driving portion 212 is provided on the other end of the driving wheel 21. Two bosses serving as driving parts 212 are protruding from the middle of one end, and the two driving parts 212 form a rotationally symmetrical structure about the axis of the driving wheel 21. The driving part 212 is connected to the driving groove 313 of the sliding member 31 to drive the sliding member 31; a matching part 213 matching with the energy storage component 22 is provided on the circumferential side wall of the driving wheel 21. In the present embodiment, four matching parts 213 are protruding from the circumferential side wall of the driving wheel 21, and the end of each matching part 213 is an arc surface, and the center angle between two adjacent matching parts 213 is 90°.

[0057] The energy storage assembly 22 includes a pair of reaction plates 221 and a pair of elastic members 222. The pair of reaction plates 221 are respectively arranged on opposite sides of the driving wheel 21 and form a rotationally symmetrical structure with respect to the driving wheel 21. The middle part of the same reaction plate 221 is respectively abutted against two adjacent matching parts 213 on the driving wheel 21. The first end of each reaction plate 221 is connected to a reaction shaft 223, and the reaction shaft 223 is connected to the support structure 1. A pair of elastic members 222 are respectively arranged on the other two sides of the driving wheel 21, one end of each elastic member 222 is connected to the reaction shaft 223, and the other end is connected to the second end of an elastic member 222.

[0058] In the initial state, the middle part of each reaction plate 221 abuts against the circumferential side wall of one end of the driving wheel 21 located between the two matching parts 213, and the spacing between the two reaction plates 221 is approximately the diameter of the circumferential side wall of the driving wheel 21. The two elastic members 222 are in the initial state, and the energy storage assembly 22 is in the energy release state at this time. The driving wheel 21 is rotated, and each reaction plate 221 rotates with the reaction axis 223 as the rotating axis. As the reaction plates 221 abut against the matching parts 213, the distance between the second ends of the two reaction plates 221 increases, and the two elastic members 222 are stretched. When the middle part of each reaction plate 221 abuts against a matching part 213, the spacing between the two reaction plates 221 is the sum of the diameter of the circumferential side wall of the driving wheel 21 and the protruding height of the two matching parts 213, and the energy storage assembly 22 is in the energy storage state at this time.

In the figure, the track grooves 111 are respectively arc-shaped through grooves. Of course, it is also possible not to set the track groove 111 on the first support plate 11. At this time, the driving wheel 21 is located between the first support plate 11 and the second support plate 12, and a gap is left between the driving portion 212 and the first support plate 11. The two ends of the driving wheel 21 are respectively rotatably cooperated with the first support plate 11 and the second support plate 12.

At the same time, the connecting holes can also limit the connecting member 32 from moving in the direction of approaching or moving away from the driving mechanism 2 as the sliding member 31 slides.

[0062] like Figure 1 , 8As shown in Figure 9, the transmission mechanism 4 includes a side plate 42 and a transmission plate 41, wherein the side plates 42 and the transmission plates 41 are arranged in pairs, each side plate 42 is vertically arranged on the support surface 10, and the two communication holes are correspondingly located between the two side plates 42, each transmission plate 41 is respectively slidably matched with a side plate 42, and each side plate 42 is located above a communication hole, each side plate 42 is linked to a linkage portion 322, and the contactor 6 is located between a pair of transmission plates 41, and a pair of transmission plates 41 are respectively linked to the contact support of the contactor 6, so as to drive the contactor 6 to open and close the switch, as shown in Figure 9.

A pressing portion 412 is also provided on the transmission plate 41. The pressing portion 412 is preferably located in the middle of the transmission plate 41, and the pressing portion 412 is located on the side facing away from the side plate 42 for cooperating with the contact support of the contactor 6.

[0063] It should be noted that the driving mechanism 2 , the transmission mechanism 4 and the supporting structure 1 of this embodiment may also adopt the existing technology, wherein the driving mechanism 2 and the transmission mechanism 4 are respectively linked with the steering mechanism 3 .

[0064] 11 and 12 provide a second embodiment of the mechanical emergency starting contactor device. In this embodiment, the structures of the supporting structure 1, the driving mechanism 2, the steering mechanism 3 and the transmission mechanism 4 are the same as those in the above embodiment.

[0065] Different from the above-mentioned embodiment, two groups of steering mechanisms 3 and one group of driving mechanisms 2 are provided in this embodiment, that is, the same driving mechanism 2 drives two steering mechanisms 3 at the same time, and each group of steering mechanisms 3 drives a corresponding group of transmission mechanisms 4, and the driving method is the same as that of the first embodiment.

[0066] like Fig.12 As shown, the two groups of steering mechanisms 3 are respectively arranged on opposite sides of the driving mechanism 2, and the two driving parts 212 of the driving wheel 21 in the driving mechanism 2 are respectively connected to the driving grooves 313 of the two sliding members 31. In this embodiment, the two groups of steering mechanisms 3 form a rotationally symmetrical structure about the axis of the driving wheel 21. When the driving wheel 21 is rotated, the two sliding members 31 approach each other or move away from each other, that is, each sliding member 31 moves in a direction approaching or moving away from the driving wheel 21. The cooperation between the linkage member 32 and the sliding member 31 in each group of steering mechanisms 3 is the same as that in the first embodiment, so that the transmission mechanism 4 can be driven to drive the contactor 6 to open and close.

[0067] In the above two embodiments, the operating member 5 includes a connecting rod 51 and a handle 52. One end of the connecting rod 51 is connected to the driving wheel 21 of the driving mechanism 2, that is, one end of the connecting rod 51 passes through the operating hole 121 and is connected to the driving hole 214 of the driving wheel 21. The other end of the connecting rod 51 is higher than the top of the contactor 6 and is equipped with a handle 52. In this way, the operating member 5 with a longer length can operate the contactor 6 from a distance, that is, when the contactor 6 is installed in the cabinet, the operating member 5 can pass out of the cabinet to operate the contactor 6 from outside the cabinet, which has the advantage of convenient operation. Of course, the operating member 5 can also adopt other existing structures.
