Abstract
The utility model relates to a dead weight stopping device for an eight-sound musical instrument, relating to a starting/ stopping device for an eight-sound box. The utility model comprises a worm wheel (1), a regulating shaft (2) with a worm screw, an inertial frame (3), a friction wheel (4), a fixed support (5) for the regulating shaft, a weight dropper (6) and a weight support (7). The utility model is characterized in that the weight support can be injected by using plastic to present a n shape, and both sides of the weight support are provided with convex lugs (8), (9) connected with the bottom plate of the eight-sound box. The utility model has the advantages of simple assemblage, high assemblage precision, and reliable motion of weight dropper; in addition, the utility model also has the advantages that the plastic is used to replace the metal, the manufacture cost is low, etc.
Description
The utility model relates to musical box, is a kind of musical box headstock gear (or claiming stop motion mechanism).
Weight support in the musical box stop motion mechanism is metal in the prior art, when the dress weight, the metal support both legs must be pushed aside laterally by force, then with the hole of the axle alignment bracket both legs of weight side, and firmly metal support is returned to original device.Defectives such as support is the U font in addition, and screw mounting hole is positioned at the weight below, must earlier support be installed on the musical box with screw during assembling, and weight is installed again, like this, exists assembling complicated, and assembly precision is low.In addition, weight support is not originally crossed the barrier element of stop generation reverse flip owing to prevent weight, so, the anti-phase upset that weight is probably crossed stop, the generation of this situation can cause weight can not carry out normal stop action, tends to be difficult to upset and gets back to the normal position because be in anti-phase weight; Also having a kind of situation is exactly that be fixed in motion process its framework top Beam friction of weight is fixed on the position and is unable to stir any more, thereby makes its ability that loses operate as normal, and locking function is lost.
The purpose of this utility model be to provide a kind of rational in infrastructure, easy to assembly, assembly precision is high, the Weight stop of the musical box of reliable in action.
For achieving the above object, the technical solution of the utility model is such: it includes speed governing axle, inertial frame, friction pulley, speed governing shaft fixing support, weight, the weight support of worm gear, band worm screw, weight support can form with plastic injection-moulded, support is " ∩ " font, there is the lug that is connected with musical movements baseboard its both sides, and the top is provided with the baffle plate that prevents that weight is offside.
Described both sides lug can be provided with the reference column that cooperates with the musical movements baseboard hole down, and outside lug can be established mounting hole on the boss from the boss that cooperates with speed governing shaft fixing support lug.
Described weight upper surface has a horizontal right angle groove that cooperates with baffle plate with the rear wall junction, and described weight bottom is useful on and fastens the button pawl that the speed governing inertial frame stops operating the speed governing axle.
One recess that cooperates with speed governing shaft fixing support protuberance is arranged at described weight support top.
Compared with prior art, the utlity model has simple in structure, easy for installation, weight reliable in action, also have to mould advantages such as substituting metal, low cost of manufacture in addition.

The utility model is described in further detail below in conjunction with drawings and Examples:
The utility model comprises speed governing axle 2, inertial frame 3, friction pulley 4, speed governing shaft fixing support 5, weight 6, the weight support 7 (seeing Fig. 1, Fig. 4) of worm gear 1, band worm screw.Weight support 7 can form with plastic injection-moulded, is " ∩ " font, and there is lug 8,9 its both sides, and the lug below is provided with reference column 11,12, cooperates with the pilot hole on the musical movements baseboard 20 respectively.Wherein outside lug 9 has the boss 14 that cooperates with speed governing shaft fixing support 5 lugs 13, has screw or rivet mounting hole 15 on the boss 14.In order to increase assembly precision weight support 7 is moved axially, recess 19 (see figure 2)s that cooperate with speed governing shaft fixing support 5 top lug 18 are arranged at support 7 tops.
Reliable in order to guarantee stop action, prevent that weight 6 from crossing " ∩ " shape doorframe or weight 6 and being fixed on can not reverse on the position by its support 7 friction-top and being difficult to upset and getting back to the normal position in motion process, set up a baffle plate 10 (see figure 1)s at the top of weight support 7, have horizontal right angle groove 16 (see figure 3)s that cooperate with baffle plate 10 at weight 6 upper surfaces with the junction of rear wall, weight 6 bottoms are established one and are used to fasten the button pawl 17 that speed governing inertial frame 7 stops operating speed governing axle 2.
The utility model only needs support 7 one is broken off with the fingers and thumb gently when dress weight 6 owing to adopted the elastoplast support, and with axle alignment bracket 7 (see figure 3)s of weight 6 both sides, loosing one's grip then gets final product, and has changed original defective of firmly installing.When weight support 7 connects with musical movements baseboard 20, at first with two pilot holes on two reference columns, 11, the 12 aligning base plates 20 of support 7 belows, the mounting hole 21 that mounting hole 15 on the boss 14 is aimed on the speed governing shaft fixing support 5 is followed fixedly (see figure 5) of base plate 20 to both with screw again.During use, (see figure 6) when the button pawl 17 in the weight 6 fastens speed governing inertial frame 3, musical box speed governing axle 2 stops operating, during disengagement, the musical box starting like this, utilizes the action of weight mass centre changing musical box, can be widely used in miniature casket, starting when lid is opened, music is played ring, when lid is shut, musical box stop, music stops.
