Abstract
The utility model discloses a linkage gear component used in a miniature operating mechanism. The linkage gear component comprises a pin shaft, a primary gear which is fixedly arranged on the pin shaft, a secondary gear which is slidably arranged on the pin shaft, a coil which is arranged on the primary gear, a magnetic yoke which is arranged on the secondary gear, returning springs which are used for pushing the secondary gear towards direction away from the primary gear, and rolling beads which are arranged between the primary gear and the secondary gear. The primary gear is provided with multiple position-specifying holes, and the rolling beads are arranged on the opening ends of the position-specifying holes. Each returning spring is arranged in the corresponding position-specifying hole, and the external side end of each returning spring is connected with each rolling bead in an abutting way so that the rolling beads protrude out of an adjoining surface, which is used for adjoining the secondary gear, of the primary gear. When the linkage gear component is used, the primary gear can be utilized to be engaged with an output gear of an external motor, and the secondary gear is engaged with a poking gear which is needed to swing in a reciprocating way so that the linkage gear component is relatively reasonable and compact in structure and good in stability.
Description
Technical field
The utility model belongs to small-sized plastic-shell switching technique field, is specifically related to a kind of linkage gear assembly for small operation mechanism.
Background technology
Electronic close/open machine in existing small-sized plastic-shell switch, its link gear generally adopts cam or eccentric wheel type structure, its less stable, structure is still needed improvements badly.
Utility model content
The purpose of this utility model is to provide a kind of structure comparatively to be simplified, the linkage gear assembly for small operation mechanism that performance is comparatively reliable and stable.
The technical scheme that realizes the utility model object is: a kind of linkage gear assembly for small operation mechanism, comprise bearing pin, and be fixedly installed on master gear on bearing pin, be slidably arranged in pinion on bearing pin, be arranged on coil on master gear, be arranged on yoke on pinion, for back-moving spring that pinion is pushed away towards the direction away from master gear, be arranged on the ball between master gear and pinion; The adjacent surface in abutting connection with pinion of master gear is provided with a plurality of spacing holes that be arranged in parallel with bearing pin bearing of trend, ball is positioned at the openend of spacing hole, each back-moving spring is arranged in a corresponding spacing hole, its outboard end is connected on ball, and makes ball protrude from master gear for the adjacent surface in abutting connection with pinion; After coil electricity, adsorb yoke, thereby overcome the elastic force of back-moving spring, drive pinion to be connected on the adjacent surface of master gear, now master gear drives pinion to rotate by the effect of frictional force.
Described master gear is on whole excircle, to be equipped with the circumference gear of the gear teeth, and pinion is on whole excircle, to only have partial arc place to be just provided with the sector gear of the gear teeth.
The utility model in use, can utilize the output gear engagement of master gear and external motor, pinion and the thumb wheel engagement that needs reciprocally swinging, and its structure is comparatively rationally compact, and stability is better.
Accompanying drawing explanation
Fig. 1 is a kind of perspective view of the present utility model;
Fig. 2 is a kind of structural representation of the assembly of linkage gear shown in Fig. 1.
Embodiment
(embodiment 1)
Fig. 1 to Fig. 2 has shown the first embodiment of the present utility model, and wherein Fig. 1 is a kind of perspective view of the present utility model; Fig. 2 is a kind of structural representation of the assembly of linkage gear shown in Fig. 1.
The present embodiment is a kind of linkage gear assembly for small operation mechanism, see shown in Fig. 1 and Fig. 2, comprise bearing pin 544, and be fixedly installed on master gear 541 on bearing pin 544, be slidably arranged in pinion 542 on bearing pin, be arranged on coil 545 on master gear, be arranged on yoke 546 on pinion, for back-moving spring 547 that pinion is pushed away towards the direction away from master gear, be arranged on the ball 548 between master gear and pinion; The adjacent surface 5411 in abutting connection with pinion of master gear is provided with a plurality of spacing holes 549 that be arranged in parallel with bearing pin bearing of trend, ball is positioned at the openend of spacing hole, each back-moving spring is arranged in a corresponding spacing hole, its outboard end is connected on ball, and makes ball protrude from master gear for the adjacent surface in abutting connection with pinion; After coil electricity, adsorb yoke, thereby overcome the elastic force of back-moving spring, drive pinion to be connected on the adjacent surface of master gear, now master gear drives pinion to rotate by the effect of frictional force.
In the present embodiment, master gear and pinion are all on whole excircle, to be equipped with the circumference gear of the gear teeth.
In the present embodiment, the two ends of spacing hole are respectively provided with a screw plug 100, for preventing that ball and back-moving spring from dropping out.
(embodiment 2)
The present embodiment is substantially the same manner as Example 1, and difference is: described master gear is on whole excircle, to be equipped with the circumference gear of the gear teeth, and pinion is on whole excircle, to only have partial arc place to be just provided with the sector gear of the gear teeth.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
Claims (2)
1. the linkage gear assembly for small operation mechanism, comprise bearing pin (544), it is characterized in that: also comprise the master gear (541) that is fixedly installed on bearing pin (544), be slidably arranged in pinion (542) on bearing pin, be arranged on coil (545) on master gear, be arranged on yoke (546) on pinion, for back-moving spring (547) that pinion is pushed away towards the direction away from master gear, be arranged on the ball (548) between master gear and pinion; The adjacent surface in abutting connection with pinion of master gear (5411) is provided with a plurality of spacing holes (549) that be arranged in parallel with bearing pin bearing of trend, ball is positioned at the openend of spacing hole, each back-moving spring is arranged in a corresponding spacing hole, its outboard end is connected on ball, and makes ball protrude from master gear for the adjacent surface in abutting connection with pinion; After coil electricity, adsorb yoke, thereby overcome the elastic force of back-moving spring, drive pinion to be connected on the adjacent surface of master gear, now master gear drives pinion to rotate by the effect of frictional force.
