Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a music box with an anti-falling protection function comprises a music box body 1, wherein a protective shell 3 is arranged on the outer side of the music box body 1, and a plurality of buffer mechanisms 4 are arranged between the music box body 1 and the protective shell 3;

buffer gear 4 includes fixed block 401, fixed block 401 welds in the inside side table wall of protective housing 3, and the equal fixedly connected with spring 402 in upper and lower both sides of fixed block 401, the flexible end of two springs 402 all rotates and is connected with connecting rod 403, the one end that spring 402 was kept away from to two connecting rod 403 all rotates with music box body 1 to be connected, after music box body 1 falls, will exert oneself through connecting rod 403 and pass to spring 402, and then the elastic force effect through spring 402 plays the effect of preventing falling the protection.

Specifically, as shown in fig. 1, one end of the connecting rod 403 away from the music box body 1 is slidably connected to the inner surface wall of the protective casing 3, and the top cover 2 and the protective casing 3 are used for protecting the music box body 1.

Specifically, as shown in fig. 1, the top of the protective shell 3 is connected with the top cover 2 in a threaded manner, a plurality of through holes 8 are formed in the top surface wall of the top cover 2, and the through holes 8 are convenient for sound to be transmitted.

Specifically, as shown in fig. 2, the plurality of buffer mechanisms 4 are all arranged circumferentially at equal angles with the center of the top end surface of the music box body 1 as the center of circle, and the plurality of buffer mechanisms 4 enable the music box body 1 to be prevented from falling at multiple angles.

Specifically, as shown in fig. 3, the top of top cap 2 and the bottom of protective housing 3 all wrap up and are equipped with cushion collar 5, and inner chamber 6 has been seted up to cushion collar 5's inside, and inner chamber 6's inside is equipped with a plurality of globular buffer blocks 7 of a plurality of, and cushion collar 5 and buffer blocks 7 all use elastic rubber material to make, and cushion collar 5 and buffer blocks 7 play absorbing effect.

The working principle is as follows: when the music box is used, firstly, the top cover 2 is rotated to be fixedly connected with the protective shell 3 through threads, and the sound emitted by the music box body 1 can be transmitted out through the through hole 8; secondly, after the protective shell 3 falls from a high place, the buffer sleeve 5 contacts with the ground firstly, because the buffer sleeve 5 is made of rubber, under the action of gravity, the protective shell 3 can extrude the buffer sleeve 5 and the plurality of buffer blocks 7 in the inner cavity 6, the buffer blocks 7 are of elastic spherical structures, and further play a role in shock absorption through the elastic action of the buffer blocks 7, meanwhile, after the protective shell 3 falls to the ground, the music box body 1 still has a downward speed under the action of inertia, further force is transmitted to the spring 402 through the connecting rod 403, the spring 402 positioned at the upper end of the fixed block 401 is compressed, the spring 402 at the lower end of the fixed block 401 is stretched, through the elastic action of the spring 402, the downward force of the music box body 1 is converted into the elastic force of the spring 402, further, the music box body 1 is prevented from hard contact with the ground, and the buffer action of the spring 402 and the buffer blocks 7 plays a role in anti-falling, and then can solve the problem that the existing music box is internally provided with an anti-falling protection mechanism through the steps.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
