Fig. 2 is the structural schematic diagram at A in Fig. 1.
In figure：1 Switch main body, 2 shells, 3 first rotating members, 4 first worm screws, 5 second rotating members, 6 second worm screws, 7 snails
Wheel, 8 third rotating members, 9 threaded rods, 10 helical gears, 11 nuts, 12 openings, 13 opening sliding slots, 14 sliding blocks, 15 closed plates, 16 connect
Bar, 17 operating levers.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of operating lever accesses convenient switching device, including Switch main body 1, the upper end of Switch main body 1
Equipped with shell 2, shell 2 uses insulating materials, and electric current is directed on shell 2 after preventing electric leakage accident, during shell 2 is
The upper end side wall of hollow structure, shell 2 is equipped with opening 12, and the inner wall of shell 2 is rotatably connected to lateral setting by the first rotating member 3
The first worm screw 4, be enclosed with sponge protective case on the first worm screw 4, prevent from abrading when rotation, and the first worm screw 4 is through shell 2
The setting of side side wall, the bottom of shell 2 by the rotation connection of the second rotating member 5 there are two the second worm screw 6 being vertically arranged, two
The screw thread of second worm screw 6 uses identical helicitic texture, two such helical gear 10 to be engaged with identical two the second worm screws 6
When, the direction of rotation of two helical gears 10 is opposite, to make the moving direction of two nuts 11 on the contrary, and two
Two worm screws 6 are located at the both sides of opening 12, and the side wall of two the second worm screws 6 is arranged with and 4 matched worm gear of the first worm screw
7, the both sides inner wall of shell 2 is rotatably connected to the threaded rod 9 being laterally arranged by third rotating member 8, and threaded rod 9 is far from
One end of three rotating members 8 be equipped with 6 matched helical gear 10 of the second worm screw, the side wall of two threaded rods 9 is arranged with and it
The upper end side wall of matched nut 11, shell 2 is additionally provided with two opening sliding slots 13, and the opening of two opening sliding slots 13 is arranged
There is dust cover, prevent dust from dropping into shell 2, and two opening sliding slots 13 are located at the both sides of opening 12, two openings
Sliding slot 13 slidably connects the closed plate 15 being laterally arranged by sliding block 14, and closed plate 15 is located at the top of opening 12, sliding
The side wall of block 14 is also connect by connecting rod 16 with sliding block 14, operating lever 17 is additionally provided in shell 2, and operating lever 17 is located at opening 12
Lower section.
When the utility model operates, the first worm screw 4 is first rotated, the first worm screw 4 nibbles with the worm gear 7 on 6 side wall of the second worm screw
It closes, worm gear 7 drives two the second worm screw 6 rotations, and the second worm screw 6 engages with helical gear 10, since two helical gears 10 are symmetrical
Be arranged, and the helicitic texture of two the second worm screws 6 is identical, thus the direction of two helical gears 10 rotation be it is opposite,
The direction of two threaded rods 9 rotation be also it is opposite, nut 11 on threaded rod 9 because there is the limitation of connecting rod 16 and sliding block 14,
So nut 11 can move on threaded rod 9 without being rotated together with threaded rod 9, nut 11 is by connecting rod 16 with sliding block
14 slide being open in sliding slot 13, and sliding block 14 drives closed plate 15 to move again, can be controlled by rotating the first worm screw 4 in this way
Being turned on and off for two closed plates 15, facilitates and is removed or placed into operating lever 17.
