Abstract
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 a soft cover with any finger to shorten the air cavity, and when the finger is released, the soft cover and the air cavity extend under the elastic force of the air cavity and the elastic force of the 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, a soft cover, a spring, and a back cover, characterized in that: The upper part of the soft cover is a hollow cylinder with holes and steps on the side, and the lower part is two long straps, one with a hole at the tail and the other with a B-cylinder with a large upper and a small lower step at the tail. The accordion-shaped hollow cavity with a round notch in the middle of the side and the spring are installed in the hollow cylinder of the soft cover, the thin sound membrane and the 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 back cover is stuck between the steps and the protruding ribs of the soft cover, and the back cover fixes the spring and the air cavity in the hollow cylinder of the soft cover. The hole on the strap is inserted into the cylinder with a larger upper part and a smaller lower part at the end of the other strap of the soft cover, and the bell is fixed to the handlebar of a bicycle or scooter. When the top of the soft 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 fingers are released, the elastic force of the spring and the air cavity causes the soft 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. BRIEF DESCRIPTION OF THE DRAWINGS
[0005] Figure 1 It is a three-dimensional schematic diagram of the present invention; Figure 2 A top view of the present invention; Figure 3 It is an AA cutaway perspective view of the present invention; Figure 4 It is a structural explosion diagram of the present invention.
[0006] In the figure: 1 air cavity; 2 sound column; 3 sound cavity; 4 sound membrane; 5 soft cover; 6 spring; 7 back cover. 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 made by pressing and releasing the top of 5 soft covers with any finger to shorten 1 air cavity to compress air and stretch 1 air cavity 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 cavities, 4 sound membranes, 5 soft covers, 6 springs and 7 back covers. Compared with the existing bells on the market, its notable feature is that the hole on one strap of 5 soft covers is installed in the B cylinder with a large upper step and a small lower step at the tail of another strap of 5 soft covers, and the bell is fixed 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 4 It can be seen that the upper and lower parts of the cylindrical accordion-shaped hollow air cavity 1 have multiple layers of wrinkles, and its cross-section is wavy. There is a round notch in the middle of the side of the air cavity 1. The upper half of the 5 soft sleeve is a hollow cylinder with holes and steps on the side. The lower half is two long straps, one with a hole at the tail and the other with a large upper and small lower step at the tail. The accordion-shaped hollow air cavity 1 with a round notch in the middle of the side and the 6 spring are installed in the hollow cylinder of the 5 soft sleeve. The thin 4 sound membrane and the hollow semi-cylindrical 3 sound cavity Installed in the 2nd sound post, the 2nd sound post is installed in the circular notch on the middle side of the 1st air cavity, the 2nd sound post has two protruding rings on the outer surface, the 2nd sound post is clamped in the circular notch of the 1st air cavity, the 7th back cover is clamped between the step of the 5th soft cover and the C protruding rib, the 7th back cover fixes the 6th spring and the 1st air cavity in the hollow cylinder of the 5th soft cover, the hole on one strap of the 5th soft cover is installed in the B cylinder with a large step on the upper and a small step on the lower end of the other strap of the 5th soft cover, and the bell is fixed to the handlebar position of the bicycle or scooter.
[0010] When the user presses the top of the 5 soft sleeves to overcome the elastic force of the 6 springs and the 1 air cavity to shorten the 1 air cavity, 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 fingers are released, the elastic force of the 6 springs and the 1 air cavity causes the top of the 5 soft sleeves 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, one of the 5 soft sleeves has 3 holes at the end of one strap, and the other strap has a B cylinder with a large upper part and a small lower step at the end. However, one of the 5 soft sleeves has one or more holes at the end, and the other strap has multiple B cylinders with a large upper part and a small lower step at the end, which is also within the protection scope of the present invention.
[0012] In this embodiment, 1 air cavity and 6 springs are installed in the hollow cylinder of 5 soft sleeves, but it is also within the protection scope of the present invention to install 1 air cavity without 6 springs.
[0013] In this embodiment, the upper half of the 5 soft covers is a hollow cylinder with holes and steps on the side, and the lower half is two long straps. However, the 5 soft covers are divided into two parts, the hollow cylinder with holes and steps on the side is one part, and the two straps are connected by a ring to form one part. Putting the ring on the step of the cylinder is also within the protection scope of the present invention.
[0014] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
