Description

bicycle horn

The present invention relates to a "bicycle horn" that can be used to alert oncoming vehicles and passers-by and has good combination strength.

According to the current common bicycle horn (60), most of them have a pressing member (61) (as shown in Figure 8). The pressing member (61) is a sphere, and an opening is formed at one end and a combined tube (62) is provided. , the combined tube (62) is provided with an internal thread, so that a resonant spring (not shown) is threaded inside, and the combined tube (62) is sleeved at one end of the pressing member (61). The group has a resonance tube (63).

When in use, the bicycle horn (60) is fixed on the handlebar of the bicycle by using the tube bundle (70), and the pressure is provided through the pressing member (61), so that the bicycle rider can use the bicycle horn (60) in an emergency. ) to make a warning sound to remind passers-by or oncoming vehicles to pay attention, which can effectively prevent accidents.

However, the conventional structure as mentioned above still has the following problems in practical application: (1) the pressing member (61), the combined tube (62) and the resonance tube (63) are simply The set will easily cause the pressing member (61), the combined tube (62) and the resonance tube (63) to separate from each other with a slight application of force, so that the bicycle horn (60) has obvious binding force. Inadequate problem; (2) The bicycle horn (60) is mounted on the bicycle handlebar in a completely open manner, and the pressing member (61), the combined tube (62) and the resonance tube (62) are 63) There is also the problem of insufficient bonding strength, so during use, it is quite easy for curious people to play with the pressing member (61) and the combined tube (62). Or the resonance tube (63) is removed and taken away, which will cause a lot of unnecessary trouble to the system.

Therefore, the inventor of the present invention took this into account and thought about the idea of creation, so he designed it based on many years of experience. After many discussions and sample tests, and many revisions and improvements, he came up with the present invention.

It is commonly known that bicycle horns have insufficient bonding strength, and this is a technical problem that needs to be solved.

The bicycle horn of the present invention includes: a pressing member, a fixed seat and a horn body, wherein the pressing member is an elastic hollow sphere with a neck extending from one end of the neck, and the center of the neck An opening is provided, and the opening is connected to the internal space of the pressing member. An annular groove is recessed on the outer periphery of the neck. The fixing base has a horn mounting part and a handle fixed in a staggered shape. The horn mounting portion and the handle fixing portion are respectively located above and below the fixing base, and a first tightening ring with a first elastic groove is formed on the horn mounting portion, and the handle fixing portion A second tightening ring with a second elastic groove is formed on the top. A first locking part is provided on both sides of the first elastic groove. A second locking part is provided on both sides of the second elastic groove. The first locking part and the second locking part respectively provide a locking unit for locking, which can be used to change the inner diameter of the first tightening ring and the second tightening ring, The horn mounting part and the handle fixing part can produce a tightening effect, and the inner wall of the first tightening ring is provided with a number of limiting blocks, and the two ends respectively form a first port and a second port. , when the pressing member is so When the neck portion is inserted into the first tightening ring from the first port, it can be evenly stuck into the ring groove with the limiting block. The horn body has a resonance tube, and the resonance tube One end of the tube is formed with an enlarged bell mouth, and the other end is connected to an extension tube, and the side end of the extension tube has a set of sockets. When a resonance reed is set in the socket, the extension tube is connected from When the second port is inserted into the neck through the opening, the first tightening ring can be locked by the locking unit provided on the first locking portion. The neck part and the extension tube can be tightened at the same time, and when the limiting block is fully clamped in the ring groove, the pressing member can be prevented from being pulled away by force again, and the positioning effect is good; This is what can constitute the bicycle horn.

(1) The bicycle horn of the present invention uses the limiting block to be clamped in the ring groove, and then tightens it with the first tightening ring to produce multiple positioning effects, allowing the pressing The components, the fixing base and the speaker body are not likely to be easily separated when pulled with force.

(2) In the bicycle horn of the present invention, the pressing member, the fixing seat and the horn body are difficult to pull and separate from each other, so the pressing member and the horn body cannot be pulled out and taken away. No worries, it can save a lot of unnecessary troubles in use.
