Description

a musical swing

technical field

The invention relates to a swing capable of emitting musical sounds as it swings.

Background technique

As everyone knows, swing is a kind of outdoor play tool that people especially children like very much. Children use swings to swing, which not only brings joy to the mood, but also exercises the body. However, the present swing has a single function, only plays a wandering effect, lacks entertainment, and cannot meet people's increasingly strong diversified needs. At present, in some outdoor sports venues, there is a music swing with a music player that can play music as long as the switch is turned on. More expensive, also waste a lot of electricity.

In order to solve the above problems, the present invention discloses a swing that can provide mechanical sounding of music as the swing swings.

In order to achieve the above object, the present invention provides the following technical solutions:

A musical swing, comprising a swing bracket and a swing body, the swing body includes a swing rod connected to the swing bracket and a swing seat connected to the bottom of the swing rod, the top of the swing rod is connected to the swing bracket through a rotating shaft, the upper part of the swing rod A first rotating shaft is provided, the first rotating shaft is connected with the first transmission rod, the first transmission rod is connected with the second transmission rod through the second rotating shaft, the second rotating shaft is fixed on the top of the swing bracket, and the second rotating shaft A plectrum is fixed, and the plectrum can follow the rotation of the second shaft. A sounding cylinder is also arranged on the top of the swing bracket. The sounding cylinder is cylindrical and hollow inside, and a protrusion is provided on the inner wall of the sounding cylinder. The plectrum Located inside the sound tube, the plectrum touches the protruding part when it is rotated.

Further, a protective cover is provided at the top of the swing bracket.

Further, a limit device is provided at the top of the swing bracket.

Further, a sound amplifier is provided at one end of the sound tube.

Further, the plectrum should preferably be comb-shaped.

Further, the paddle is parallel to the axis of the third rotating shaft.

Beneficial effect:

By swinging back and forth on the swing, it can drive the plectrum in the sound tube to rotate, thus producing a wonderful music sound. The frequency of music performance changes with the swing range of the swing, which greatly enhances the fun and improves children's rhythm and sense of rhythm. , Promote brain development. Simultaneously, the swing provided by the invention generates sound through machinery, saves energy, is very environmentally friendly, and has broad space for promotion.

detailed description

The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

Embodiment one:

As shown in Figures 1 to 5, a musical swing includes a swing bracket 1 and a swing body, the swing body includes a swing rod 2 connected to the swing bracket and a swing seat 3 connected to the bottom of the swing rod 2, the The top of the swing rod 2 is connected with the swing bracket 1 through the rotating shaft 4, and the upper part of the swing rod 2 is provided with a first rotating shaft 5, and the first rotating shaft 5 is connected with the first transmission rod 6, and the first transmission rod 6 is connected with the second transmission rod 7 through the second rotation shaft 7. The two transmission rods 8 are connected, and the end of the second transmission rod 8 away from the second rotating shaft 7 is provided with a third rotating shaft 71, and the third rotating shaft 71 is fixed on the top of the swing bracket 1, and a dial is fixed on the third rotating shaft 71. Sheet 10, plectrum 10 can follow described third rotating shaft 71 to rotate, and the top of swing bracket 1 is also provided with sounding tube 9, and described sounding tube 9 is cylindrical, and its interior is hollow, and the inner wall of sounding tube 9 is provided with protrusion, According to the different positions of the protrusions, different syllables in the scale can be produced. The plectrum is arranged inside the sounding cylinder, and the plectrum 10 touches the protrusions 91 when rotating, thereby producing wonderful music. When the swing is swinging, the swing rod 2 swings back and forth, and through the cooperation of the first transmission rod 6, the second transmission rod 8, and the first rotating shaft 5 and the second rotating shaft 7, finally drives the third rotating shaft 71 to rotate, and the plectrum 10 also Rotate accordingly, and due to the cooperative action of the transmission rod and the rotating shaft, the second rotating shaft 7 can rotate around the axis for one circle. When the swing bracket swings relatively large, the plectrum 10 can be made to form a circular motion, so that it can completely run on the inner wall of the sounding tube 9 for a week, and all the protrusions on the inner wall of the sounding tube 9 move the plectrum in turn, thereby playing a complete a piece of music.

Further, the paddle 10 is parallel to the axis of the third rotating shaft 71 .

Embodiment two:

As an improved solution of the first embodiment, a protective cover 11 is provided at the top of the swing bracket 1 . The protective cover can protect various transmission parts and sounding parts on the top of the swing bracket from being damaged. The remaining technical features in this example are the same as those in Embodiment 1.

Embodiment three:

As an improved solution of Embodiment 1 or 2, limit devices 12 are provided on both sides of the top end of the swing bracket 1 . The limit device 12 can ensure that when the swing swings to the maximum extent, the plectrum 10 just completes one rotation. The remaining technical features in this example are the same as those in Embodiment 1.

Embodiment four:

Considering that the sound tube is set on the top of the swing bracket, and the swinger is sitting at the bottom of the swing, the sound effect of the sound tube is poor. As an improvement, a sound amplifier 13 is provided at one end of the sound tube. The sound amplifier is preferably a simple horn shape (of course, it can also be a broadcast horn). On the basis of being able to amplify the sound effect, it is very environmentally friendly and saves energy. If the top of the swing support 1 is provided with a protective cover, the sound amplifier 13 should be drawn out of the protective cover, and the protective cover is airtight and produces a certain reverberation effect, and the sound can be effectively amplified by the sound amplifier. The rest of the technical features in this example are the same as those in Embodiment 1, 2 or 3.

Embodiment five:

Further, the plectrum 10 should preferably be comb-shaped. The comb-shaped plectrum 10 should be made of metal, and when it comes into contact with the protrusion on the inner wall of the sound tube, the rack of the plectrum 10 will be bounced to make a crisp sound, which is very beautiful. The rest of the technical features in this example are the same as those in Embodiment 1, 2, 3 or 4.

It must be noted that the figure is only a schematic diagram, and the ratio between the transmission rods should not be a limitation of the present invention, and those skilled in the art can modify the ratio according to needs to achieve a better rotation effect.

The technical means disclosed in the solutions of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for those skilled in the art, some improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
