DETAILED DESCRIPTION

[0025] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0026] Example 1

[0027] like Figure 1-Figure 6 As shown, in this embodiment, an intermittent action transmission structure applied to a high-voltage switch operating mechanism is provided, comprising:

[0028] The power transmission part 2 includes a driving plate group 202, and a roller shaft 204 is provided on the driving plate group 202;

[0029] The power output part 3 includes a groove wheel 302. A groove 303 is provided on the side wall of the groove wheel 302. When the driving plate group 202 rotates, the protrusion 203 brings the roller 204 into the groove 303 to drive the groove wheel 302 to rotate. The groove wheel 302 is connected with a power output member. The power output member can be an output rod 301. The output rod 301 is fixed on the rotating shaft of the groove wheel 302. The lower end of the output rod 301 is provided with a spline or a coupling to facilitate the output of the power of the output rod 301.

[0030] Among them, a locking arc is arranged on the driving plate assembly 202, and a locking groove 304 is arranged on the side wall of the groove wheel 302 and on both sides of the groove 303, and the two locking grooves 304 are alternately engaged with the locking arc to maintain the stability of the switch opening or closing action.

[0031] The locking arc includes a plurality of roller shafts 205 , and the plurality of roller shafts 205 are evenly distributed and rotatably connected to the side positions of the driving plate assembly 202 .

[0032] The driving plate group 202 includes two installation disks 2021 arranged at intervals, and multiple roller shafts 205 rotate between the two installation disks 2021. A protrusion 203 is provided on one side of the driving plate group 202, and a roller shaft 1 204 is provided at one end of the protrusion 203 away from the driving plate group 202. The protrusion 203 includes two protrusion pieces 2031 arranged at intervals, and the two protrusion pieces 2031 are respectively connected to the two installation disks 2021, and the roller shaft 1 204 is installed between the two protrusion pieces 2031.

[0033] The intermittent transmission structure is also provided with a power drive unit 1, which includes a rotatable worm 102. The worm 102 is driven to rotate by the motor 101. The power output end of the motor 101 is connected to one end of the worm 102. When the motor 101 is started, the power output end of the motor 101 will drive the worm 102 to rotate. A worm wheel 201 is rotatably connected to the driving plate group 202. The worm wheel 201 is connected to the driving plate group 202 in the form of a coaxial line. The worm 102 is meshed with the worm wheel 201. The screw 102 cooperates with the worm wheel 201 to generate self-locking for the worm wheel 201, thereby improving stability.

[0034] How it works:

[0035] The motor 101 provides energy to drive the worm 102 to rotate, and the worm 102 drives the worm wheel 201 to rotate. Since the worm wheel 201 and the driving plate group 202 are an integrated structure, the driving plate group 202 rotates together with the worm wheel 201. When the roller shaft 204 on the driving plate group 202 is inserted into the groove 303 of the groove wheel 302, the output shaft 301 integrated with the groove wheel 302 is driven to rotate together. When the roller shaft 204 on the driving plate group 202 leaves the groove 303 of the groove wheel 302, the output shaft 301 stops rotating, and at the same time, the locking groove 304 of the groove wheel 302 is meshed with the locking arc of the driving plate group 202 to complete a switch opening or closing action;

[0036] refer to Figure 2-Figure 4 , Figure 3 The state shown is the switch-on state. When the starting motor 101 drives the worm 102 to rotate, the worm wheel 201 drives the driving plate assembly 202 to rotate. Figure 3 The roller 204 rotates in the direction of the arrow shown in FIG. 304 . Figure 4 As shown in FIG. 1 , under the cooperation of the roller 204 and the groove 303, the groove wheel 302 rotates together with the output shaft 301 to the position as shown in FIG. Figure 2The state shown in FIG. 1 stops. At this time, the switch is in the open state, thus completing the opening action of the switch. Similarly, the worm gear 201 drives the drive plate assembly 202 according to Figure 2 Rotating in the direction of the arrow shown can complete the closing action of the switch. The closing action of the switch is the same as the opening action, so it is not described in detail.

[0037] like Figure 1 , Figure 2 As shown, in an emergency state (for example, when the motor 101 is damaged and cannot be started), in order to manually drive the worm 102 to rotate so as to manually complete the opening and closing operations of the switch, a manual operation port 4 is opened at the end of the worm 102 away from the motor 101. The manual operation port 4 is U-shaped. In an emergency state, an external tool (for example, a flat-blade screwdriver or a special tool) is inserted into the manual operation port 4, and the external tool is rotated to manually drive the worm 102 to rotate, thereby manually opening and closing the switch.

[0038] like Figure 1 , Figure 6 As shown, in order to connect the worm gear 201 and the drive plate assembly 202 together, a connecting shaft 5 is fixed at the center of the worm gear 201, and two mounting plates 2021 are fixedly sleeved on the connecting shaft 5, as shown in FIG. Figure 6 As shown, a limit block is provided on the connecting shaft 5, and a limit groove matched with the limit block is provided on the central hole wall of the two mounting plates 2021. When the limit block cooperates with the limit groove, the driving plate group 202 and the worm gear 201 can be ensured to rotate synchronously.

[0039] Example 2

[0040] like Figure 5 , Figure 6 As shown, on the basis of Example 1, in order to quickly assemble the power transmission part 2, both ends of the roller shaft 1 204 and the plurality of roller shafts 205 are provided with plug connectors 9, and the side walls of the mounting plate 2021 and the protruding piece 2031 are provided with plug holes 7, and the plug connectors 9 are plugged into the corresponding plug holes 7, and the upper end of the connecting shaft 5 is connected to a pressing block 8 for pressing the mounting plate 2021 through a bolt 6;

[0041] The assembly process of the power transmission unit 2 is as follows:

[0042] Install roller shaft 205 between the two mounting plates 2021, and install roller shaft 1 204 between the two protruding pieces 2031. At this time, the two mounting plates 2021 are sleeved on the connecting shaft 5, and then the pressure block 8 is buckled on the connecting shaft 5 and tightened with the bolt 6. The pressure block 8 is used to press the mounting plates 2021, and then the two mounting plates 2021, roller shaft 205, roller shaft 1 204 and the two protruding pieces 2031 can be fixed on the connecting shaft 5, so as to realize the rapid assembly of the power transmission part 2 and improve the installation efficiency.

[0043] like Figure 6 As shown, a support sleeve 10 is sleeved between the two mounting disks 2021 and on the connecting shaft 5. The support sleeve 10 can limit the interval between the two mounting disks 2021. The height of the support sleeve 10 is slightly larger than the height of the second roller shaft 205, thereby preventing the two mounting disks 2021 from squeezing the second roller shaft 205 too tightly and ensuring smooth rotation of the second roller shaft 205.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
