Abstract

The utility model relates to a sound production rotation ware of moving away to avoid possible earthquakes, it discloses one and has elastic sound production spring of moving away to avoid possible earthquakes, sound production spring of moving away to avoid possible earthquakes includes a curved sound production steady arm (2), and circular-arc arm (1) of moving away to avoid possible earthquakes, arm shake arm (1) central authorities have an axle core, have a rotatable gear (3) on the axle core, it is fixed mutually with certain angle with the one end of sound production steady arm (2) to move away to avoid possible earthquakes arm (1) one end, the other end of sound production steady arm (2) has one in the gear orientation one side can with gear (3) meshed gear latch, gear (3) below have one rather than meshed gear. The utility model discloses have to the restriction of drive mechanism, fixed, avoid possible earthquakes and the function of sound production.

Description

Sounding shock-absorbing rot

The utility model relates to machinery, the transmission part of toy and sounding parts.

At present, all promising its transmission in the product of machinery, toy etc., sounding and be provided with some equipment or parts makes the transmission of its machinery or toy, and sounding is smooth.But present implementation methods be comprise the limiting gear rotational speed in the transmission, the shock-absorbing when gear stops operating on fixed gear slip, face of gear and the gear and these four aspects of need sounding all will be disaggregatedly introduce a set of equipment or parts in design, in making, cause design complicated like this, procedure is many and machining accuracy is strict, body is huge and heavy, and is with high costs.

The purpose of this utility model provides a kind of sounding shock-absorbing rot, and can collect the restriction of driving mechanism, fixing, shock-absorbing and required sounding four functions is one, simplicity of design, and procedure is few, and machining accuracy is loose, the body miniaturization, in light weight, cost is low.

Technical solution of the present utility model is that a flexible sounding shock-proof spring is arranged, the sounding shock-proof spring comprises the sounding arm of stability of an arc, and circular-arc shock-absorbing arm, there is an axle core in shock-absorbing arm central authorities, on the axle core a rotatable gear is arranged, one end of its shock-absorbing arm one end and the sounding arm of stability fixes at a certain angle, the other end of the sounding arm of stability on gear one side, have one can with the gear latch of gear engagement, there is its meshed gears face the gear below.

One end of shock-absorbing arm one end of the present utility model and the sounding arm of stability fixes at a certain angle, and this angle is to decide according to different product used gear size, radius.

Working principle of the present utility model is in working order the time, the latch of the sounding arm of stability places on the gear, when gear rotates, latch can promote with the tooth of gear upwards to move, move past the tooth top of gear when latch after, under the elastic force pressure effect of the sounding arm of stability, latch hits the tooth root portion of gear down rapidly and sends the sound of " clatter ", in gear continues to rotate, will send " clatter, clatter ... " sound.The purpose that the rotating speed of the gear of the sounding arm of stability in can also stable rotation and realizing limits.When state of rest, can play the effect of fixed gear, thereby fix face of gear again by gear.The shock-absorbing arm has weakened the vibrations of gear and face of gear because of having elasticity.

Four functions that the utility model has the advantages that the restriction that can collect driving mechanism, fixing, shock-absorbing and required sounding are one, simplicity of design, and procedure is few, and machining accuracy is loose, this miniaturization of machine, in light weight, cost is low.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Fig. 1: organigram of the present utility model;

Fig. 2: sounding shock-proof spring organigram of the present utility model;

Fig. 3: sounding shock-proof spring of the present utility model is loaded onto the organigram behind the gear;

According to Fig. 1,2, shown in 3, the utility model has a rubber-like sounding shock-proof spring, the sounding shock-proof spring comprises the sounding arm of stability 2, and the circular-arc shock-absorbing arm 1 of an arc, there is a core in shock-absorbing arm 1 central authorities, on the axle core a rotatable gear 3 is arranged, one end of its shock-absorbing arm 1 one ends and the sounding arm of stability 2 fixes at a certain angle, the other end of the sounding arm of stability 2 on gear one side, have one can with gear 3 meshed gears latches, gear 3 belows have one with its meshed gears face 4.

Claims

1. sounding shock-absorbing rot, it is characterized in that having a rubber-like sounding shock-proof spring, the sounding shock-proof spring comprises the sounding arm of stability (2) of an arc, and circular-arc shock-absorbing arm (1), there is a core in shock-absorbing arm (1) central authorities, on the axle core a rotatable gear (3) is arranged, one end of its shock-absorbing arm (1) one end and the sounding arm of stability (2) fixes at a certain angle, the other end of the sounding arm of stability (2) on gear one side, have one can with gear (3) meshed gears latch, gear (3) below have one with its meshed gears face (4).
