The driving bevel gear 21 is engaged with the driven bevel pinion 301, the driven pinion 302 and the No.1 tooth The lower gear 82 of wheel 31 engages, and the gear 81 of the No.1 gear 31 is engaged with the lower gear 82 of No. two gears 32, institute The gear 81 for stating No. two gears 32 is engaged with the lower gear 82 of No. three gears 33, the gear 81 of No. three gears 33 It is engaged with the lower gear 82 of No. four gears 34, the gear 81 of No. four gears 34 is engaged with the core gear 351；

The driver 2 drives the driving bevel gear 21 to rotate, the driven gear component 30, No.1 gear 31, two Number 32, No. three gears 33 of gear and No. four gears 34 are driven successively, and the core gear 351 is made to rotate.

It illustrates further, the design's is coaxial by No.1 gear 31 and No. three gears 33, No. two gears 32 and No. four Gear 34 is coaxial, and the vertical rotation of driving bevel gear 21 is converted to horizontally rotating for driven bevel pinion 301 by gearing Effect, and make driven pinion 302,33, No. four gears 34 of the gear of gear 32, three of No.1 gear 31, two and core gear 351 are driven successively, and gear one layer is driven integral into vertical direction last layer, dexterously save transmission component 3 in shell 1 Vertical space；Achieve the effect that core gear 351 rotates, and makes driving bevel gear 21 slow down, increases system middle gear again simultaneously Torsion；

And the driving bevel gear 21 and driven bevel pinion 301 of the design is bevel gear, the two passes through between umbrella tooth and umbrella tooth Between side be engaged, have maximum contact ratio, the thickness of its umbrella tooth is small in addition, can energy expeditiously be reached transmission In component 3, so the collision loss of bevel gear and bevel gear is low, reach transmission efficiency raising and the starting current made in system Low effect.

In conclusion the bevel gear of the design and bevel gear engage, coordinate the driven gear component 30, one in the design Number gear 33, four of gear 32, three of a gear 31, two mutual floor on vertical direction between gear 34 and core gear 351 One layer of meshing relation makes space of the transmission component 3 in shell 1 in the design be conserved, and the specification of shell 1 is minimum, again Make that there is higher transmission efficiency and lower starting current in transmission system.

It illustrates further, the core gear 351 is located at the edge of the shell 1, and the shell 1 is made to be surrounded by half in institute Core gear 351 is stated, the gear of the core gear 351 is exposed to the outside of the shell 1.

It illustrates further, the core gear 351 of the design is reduced core gear 351 and contacted outside by 1 semi-surrounding of shell The region on boundary, only a small amount of gear expose one end of shell 1, or a small amount of gear is exposed to one end of shell 1 and its adjacent side Face effectively provides core gear 351 effect of anti-oxidation, Anti-dislocation and anti-screens, while also providing multiple meshing points with suitable Gear with multiple and different external connection modules；

It is empty that core gear 351 can be effectively reduced into occupancy of the gear parts of core gear 351 in shell 1 simultaneously Between, make the design has volume smaller, but the effect that transmission efficiency is constant.

Illustrate further, in 31, No. two gears 32 of the No.1 gear and No. three gears 33, the gear 81 it is straight Diameter is not more than the lower gear 82.

It illustrates further, in 31, No. two gears 32 of No.1 gear of the design and No. three gears 33, the gear of three 81 be all pinion gear, and pinion gear only needs to engage with another gear, because of the gear that volume is bigger, the energy of loss is got over It is more, and without using the gear that volume is larger under identical function and effect, it is using small or small radius gear 81 It can reach and effectively save energy, the energy utilization in raising system.

It illustrates further, the shell 1 is equipped with arcwall face structure 12, institute at one end in the core gear 351 Arcwall face structure 12 is stated to extend to another side of the shell 1 at radian from a side of the shell 1.

It illustrates further, arcwall face is equipped at shell 1, arcwall face is used to improve the aesthetic appearance of the design, is also convenient for The gears of other module institute bands of door lock engages in arcwall face structure 12 with core gear 351, solves in the prior art The problem of shape dullness.

It illustrates further, the core rotary components 35 further include：Bearing 352 and rotation axis 353；

The bearing 352 is fixed on the shell 1, and the core gear 351 is installed on the rotation axis 353, the axis Hold 352 both ends for being rotatably fixed on the rotation axis 353 respectively.

It illustrates further, the bearing 352 of the design is ball bearing, and cooperation rotation axis 353 uses, by No. four gears 34 Lower gear 82 core gear 351 is acted on, keep rotation axis 353 rotatable, and the core gear 351 of the design be connected with it is existing The bolt component of technology is released or is pushed by rotating the lock tongue that core gear 351 achievees the effect that control in bolt component.

Shell 1 limits the position of core gear 351, in the state that both sides are all compressed, core gear by bearing 352 351 have locked the position coordinated with the gear of No. four gears 34 81, therefore can guarantee that core gear 351 will not misplace, and improve The position of core gear 351 is stablized, and ensure that the overall operation of reduction box is normal.

It illustrates further, the shell 1 includes successively from top to bottom at the perpendicular where the bearing 352： Mounting groove 13 and dashpot 14；

The mounting groove 13 is for being fixedly mounted the bearing 352；The both ends of the dashpot 14 are connected to described The inner wall of mounting groove 13 and the shell 1.

It illustrates further, the mounting groove 13 of the design is used for fixing bearing 352, and the vertical direction of bearing 352 connects Have a dashpot 14, dashpot 14 can effectively reduce internal influence of the extraneous impact to shell 1, such as energetically switch gate when, Such as cotton, foam or paper scrap can be added in dashpot 14 to be filled it, achieve the effect that vibration damping.

It illustrates further, the outside of the shell 1 sets Packed buffering protective case 15；

The buffering protective case 15 is fixed on the region that the shell 1 carries the transmission component 3.

It illustrates further, the mounting groove 13 of the design is used for fixing bearing 352, and the vertical direction of bearing 352 connects There are dashpot 14, dashpot 14 to be connected with buffering protective case 15 further through the outer wall of shell 1, when shell 1 is impacted, cannot influence To the structure of the transmission component 3 in shell 1, the engagement of especially each gear；Therefore the material of the buffering protective case 15 of the design is The material of elastomer, the elastomer can be elastically-deformable material, and such as rubber, punching can be disperseed when large impact by reaching The vibration hit, and protect the effect inside shell 1.

It illustrates further, the outside of the shell 1 is equipped with wire clamp 16；

The shell 1 is equipped with string holes 17 at the driver 2；The string holes 17 and 16 homonymy of the wire clamp.
