Description

Technical Field

[0001] This utility model relates to a transmission-type changeover switch. Background Technology

[0002] Currently, most changeover switches on the market use a handle to drive a square shaft for gear switching. However, when encountering heavier gears or higher torque, the torque required to turn the handle is too large, and on-site conditions do not allow for the installation of a large handle, making the changeover switch less quick and convenient to operate. The overall protection of the changeover switch is also poor, with the bearings and screws exposed, which can easily cause accidental activation and poses a certain risk. Based on previous changeover switches, the positioning mechanism (positioning seat, pulley, self-resetting spring, limit wheel, ratchet) has been reduced, optimizing the structure and saving materials. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings, provide a transmission-type changeover switch, and increase the protection level to solve the functional deficiencies.

[0004] The purpose of this utility model is achieved as follows: A transmission-type changeover switch includes a handle assembly and a base assembly. A flip cover is fastened into a groove in the base assembly. A self-resetting disc is mounted on top of the base assembly. A self-resetting wheel and a torsion spring are mounted in the self-resetting disc and connected to the lower cam of the self-resetting wheel through a slot. The handle assembly is mounted in the upper groove of the self-resetting wheel, and a mounting plate is fastened on top of the self-resetting wheel and fixed as a whole with a screw and a fastening nut. Gear 1 is installed in the upper shaft hole of the handle assembly. The upper slot of gear 1 forms a limit with the internal bracket of the mounting plate. Gear 2 is installed in the left slot of the mounting plate and meshes with gear 1. The emblem frame is fixed to the mounting plate with four emblem screws and four nuts. The panel is snapped onto the emblem frame. The handle is installed on gear 2 with a cross-head screw and tightened.

[0005] The rotating handle assembly consists of a rotating handle connected to a square shaft via screws.

[0006] The base assembly consists of an upper base, a base, a rear cover, a flip cover, a stationary contact assembly, a drive rod assembly, and a cam.

[0007] The beneficial effects of this utility model are: When operating the handle of this transmission-type changeover switch, gear two drives gear one to rotate, overcoming the torque of the torsion spring, allowing for easy operation of the changeover switch and realization of various functions; the flip cover effectively blocks and prevents accidental touches, and increases the protection level.

[0016] See Figures 1 to 7 This utility model relates to a transmission type changeover switch, which includes a handle assembly 11 and a base assembly 15.

[0017] The rotating handle assembly 11 is formed by connecting the rotating handle and the square shaft with screws to make them a whole; the base assembly 15 consists of an upper base, a base, a rear cover, a flip cover, a stationary contact assembly, a drive rod assembly, and a cam.

[0018] The flip cover 16 is fastened into the groove of the base assembly 15 to increase the protection level; the self-resetting disc 14 is installed above the base assembly 15, reducing the positioning seat mechanism and optimizing the material; the self-resetting wheel 13 and the torsion spring 12 are installed in the self-resetting disc 14 and connected to the lower cam of the self-resetting wheel 13 through a slot. At this time, the torsion spring 12 has a large torque, making it difficult to directly rotate the square shaft with the handle. The rotating handle assembly 11 is installed in the upper groove of the self-resetting wheel 13, and the mounting plate 8 is fastened above the self-resetting wheel 13 and fixed as a whole with the screw 9 and the fastening nut 17.

[0019] Gear 16 is installed in the upper shaft hole of the handle assembly 11. The upper slot of gear 16 forms a limit with the internal bracket of the mounting plate 8. Gear 27 is installed in the left slot of the mounting plate 8 and meshes with gear 16. The emblem frame 5 is fixed to the mounting plate 8 with four emblem screws 4 and four nuts 10. Finally, the panel 3 is snapped onto the emblem frame 5, and the handle 2 is installed on gear 27 with a cross-head screw 1 and tightened. This completes the installation of this type of transmission changeover switch.

[0020] In this type of transmission-type changeover switch, when the handle is operated, gear 2 7 drives gear 1 6 to rotate. When the handle 2 is rotated 45° to the left or right, gear 2 7 can rotate 45° synchronously, and gear 1 6 only needs to rotate 18° to complete the operation. This overcomes the torque of the large torsion spring, making it easy to operate the changeover switch and realize various functions. The flip cover 16 can effectively block and prevent accidental touch, and increase the protection level.
