Embodiment 1

[0031] Such as Figure 1-7 As shown, a switch with a locking device includes a knob assembly 1 and a housing 3. The knob assembly 1 includes a knob 11, a limit pin 12 and a rotating shaft 13. The limit pin 12 is arranged on the On the rotating shaft 13 and close to the knob 11, the limit pin 12 is movably connected with the rotating shaft 13, and the large return spring 6 is set at the bottom of the rotating shaft 13, and the housing 3 is provided with a gear Block 4, the switch controls the limit pin 12 to cooperate with the gear block 4 by controlling the lifting of the rotating shaft 13, there is at least one gear block 4, and the switch has at least one gear.

[0032] In this embodiment, the limiting pin 12 is loosely matched with the rotating shaft 13, and a channel is provided on a diameter line of the radial section of the rotating shaft 13, and the limiting pin 12 is located on the rotating shaft 13. Only one end of the limit pin 12 protrudes out of the passage.

Abstract

The invention relates to a switch with a locking device. The switch comprises a turn button assembly and a housing. The turn button assembly comprises a turn button, a limiting pin and a rotating shaft. The limiting pin is arranged on the rotating shaft and is close to the turn button. The limiting pin is movably connected with the rotating shaft. A large reset spring is arranged on the lower part of the rotating shaft. The housing is provided with a gear block. The switch controls the lifting of the rotating shaft so as to control the matching between the limiting pin and the gear block, the number of the gear block is at least one, and the switch is provided with at least one gear. According to the invention, functions corresponding to different gears are output, switching between two or more modes is random, an interlocking function is realized, and false operation is prevented.

Description

technical field [0001] The invention belongs to the field of electric control equipment and relates to a switch with a locking device. Background technique [0002] Ordinary switches, the knob is rotated under force, and the corresponding functions can be output when corresponding to different gear positions, but for some functions, misoperation is not allowed, such as the anti-aircraft light switch on military vehicles, in addition to having the light control function of civilian vehicles In addition, it also needs to have the light control function in the air defense mode during combat. The two modes cannot be switched at will, and an interlock function is required to prevent misuse. Therefore, some switches require a conduction lock function, that is, when the switch is turned on, it is locked, so that the switch remains in the conduction state. The existing locking mechanism of a switch that realizes conduction locking generally consists of a lock twist, a guide rod and...
