Description

Technical Field

[0001] The invention relates to the technical field of bells, and in particular to a bell that produces sound by compressing air. Background Art

[0002] Bells are widely used in transportation vehicles such as bicycles, electric bicycles and scooters. Most bells make sounds by using the thumb to poke an object and hit it against a metal object. Most bells have a brake handle installed between the handlebars, which makes it inconvenient to press the bells. The rotating bells used on shared bicycles will slip on the handlebars and make no sound after being used for a period of time. Summary of the invention

[0003] The purpose of the present invention is to provide a bell which can compress air by pressing the upper cover with any finger to shorten the air cavity, and when the finger is released, the air cavity extends under the action of elastic force and spring, and the air quickly runs out of and into the gap between the sound cavity and the sound membrane, causing the sound membrane to vibrate and produce sound.

[0004] To achieve the above object, the present invention provides the following technical solution: a bell that produces sound by compressing air, comprising an air cavity, a sound column, a sound cavity, a sound membrane, an upper cover, a lower cover, a binding strap, and a spring, characterized in that: The upper cover and the lower cover are provided with blocks around one side, and an accordion-shaped hollow cavity with a round notch in the middle of the side is installed in the upper cover and the lower cover, a thin sound membrane and a hollow semi-cylindrical sound cavity are installed in the sound column, and the sound column is installed in the round notch in the middle of the side of the air cavity. The spring connects the cylinders at the four corners of the upper cover and the lower cover, and the cylinders at the four corners of the upper cover and the lower cover have inverted buckles to prevent the springs from detaching from the cylinders. The two ends of the elastic straps are hung in the grooves on both sides of the lower cover to fix the bell to the handlebar position of the bicycle or scooter. When the upper cover is pressed to overcome the elastic force of the spring and the air cavity to shorten the air cavity, the air in the air cavity is compressed and quickly runs out from the gap between the sound membrane and the sound cavity, causing the thin sound membrane to vibrate and make a sound. When the upper cover is released, the elastic force of the spring and the air cavity causes the upper cover to rise, and the air cavity stretches, causing the air to quickly enter the air cavity from the gap between the sound membrane and the sound cavity, causing the sound membrane to vibrate and make a sound.

[0006] In the figure: 1 air cavity; 2 sound column; 3 sound cavity; 4 sound membrane; 5 upper cover; 6 lower cover; 7 strap; 8 spring. DETAILED DESCRIPTION

[0007] The technical solution of the present invention is further described below in conjunction with the drawings of the embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0008] from Figure 1 It can be seen that the present invention provides a bell which can be installed under any finger by pressing and releasing 5 upper covers to shorten 1 air cavity to compress air and 1 air cavity to stretch to inhale air, and the air quickly runs out of and into the gap between 3 sound cavity and 4 sound membrane to make 4 sound membrane vibrate and make sound. The bell is composed of 1 air cavity, 2 sound columns, 3 sound cavity, 4 sound membrane, 5 upper covers, 6 lower covers, 7 straps and 8 springs. Compared with the existing bells on the market, the bell has the following notable feature: the two ends of 7 elastic straps are clamped in the grooves on both sides of 6 lower covers to fix the bell on the handlebar of a bicycle or a scooter, the bell can be installed under any finger of the user, and the user can press the bell at any time to make it make sound during use.

[0009] from Figures 2 to 6 It can be seen that the cylindrical accordion-shaped air cavity 1 has multiple layers of wrinkles on the top and bottom, and its cross section is wavy. There is a circular notch in the middle of the side of the air cavity 1. There are blocks around one side of the 5 upper cover and the 6 lower cover. The 1 air cavity is installed in the blocks of the 5 upper cover and the 6 lower cover. The thin 4 sound membrane and the hollow semi-cylindrical 3 sound cavity are installed in the 2 sound columns. The 2 sound columns are installed in the circular notch in the middle side of the 1 air cavity. There are two protruding rings on the outer surface of the 2 sound columns, which clamp the 2 sound columns in the circular notch of the 1 air cavity. There is a C cylinder at each of the four corners of the cover and the lower cover 6, the head diameter of the C cylinder is smaller than the bottom diameter, and the outer surface of the bottom of each C cylinder has a D undercut, and the 8 spring is installed on the C cylinder of the upper cover 5 and the lower cover 6, and the D undercut prevents the 8 spring from detaching from the C cylinder. There is an arc-shaped groove under the lower cover 6, and there are multiple horizontal strips at both ends of the strap 7. When the handlebars of the bicycle or scooter are of different sizes, the horizontal strips of the strap 7 at the appropriate position can be hung in the grooves on both sides of the lower cover 6.

[0010] When the user presses the upper cover 5, the elastic force of the 8 springs and the 1 air cavity is overcome to shorten the 1 air cavity, and the air in the 1 air cavity is compressed and quickly runs out from the gap between the 4 sound membrane and the 3 sound cavity, causing the thin 4 sound membrane to vibrate and make a sound. When the upper cover 5 is released, the elastic force of the 8 springs and the 1 air cavity causes the upper cover 5 to rise, and the 1 air cavity stretches, causing the air to quickly enter the 1 air cavity from the gap between the 4 sound membrane and the 3 sound cavity, causing the 4 sound membrane to vibrate and make a sound.

[0011] In this embodiment, the shape of the air cavity is a cylinder, but the shape of the air cavity is a round air bag, a cuboid, a cube, a sphere or a combination thereof, which is also within the protection scope of the present invention.

[0012] In this embodiment, there is only one air cavity 1, but it is also within the protection scope of the present invention that two or more air cavities 1 are superimposed between the upper cover 5 and the lower cover 6.

[0013] In this embodiment, there are two layers of wrinkles on each of the upper and lower sides of the air cavity 1, but it is also within the protection scope of the present invention that there is one layer or multiple layers of wrinkles on each of the upper and lower sides of the air cavity 1.

[0014] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
