Abstract
The utility model discloses a portable manual piston type air horn, which comprises a horn body, a piston shell and a guide plate. The guide plate is provided with a through hole, a piston rod penetrates through the through hole of the guide plate, one end of the piston rod in the piston shell is provided with a piston, the other end of the piston rod outside the piston shell is provided with a handle, a spring which can reset the piston is arranged in the piston shell, the end of the piston rod with the handle is provided with a cylindrical boss matched with the through hole of the guide plate in a rotating way, the middle part of the piston rod between the cylindrical boss and the piston comprises a strip convex rib, the radial radius of the cylindrical boss is less than the radial height of the convex rib, and the through hole of the guide plate is provided with a gap matched with the strip convex rib in a sliding way. When the piston rod is accommodated in the piston shell, the guide plate can limit outward extension of the piston rod only through slightly rotating the piston rod for a certain angle so that the strip convex rib on the piston rod and the gap on the through hole of the guide plate are misaligned. The portable manual piston type air horn has simple structure and is convenient to use.
Description
Technical field
The utility model relates to a kind of loudspeaker, especially a kind of portable manual piston type pneumatic loudspeaker.
Background technology
Manually the piston type pneumatic loudspeaker are made up of speaker body, piston shell, guide plate usually, speaker body is connected with the gas outlet of piston shell, constituting one between piston shell and the guide plate can be for the cavity volume of piston activity, guide plate is provided with through hole, be equipped with piston rod in the through hole of guide plate, one end of the piston rod in piston shell is provided with piston, the other end of the piston rod outside piston shell is provided with handle, be provided with the spring that makes piston reset in the piston shell, constitute complete manual piston type pneumatic loudspeaker.Owing to be located at the elastic reaction of the spring that makes piston reset in the piston shell, so the major part of piston rod all is exposed at outside the piston shell, the utmost point is not easy to place when carrying or storing, and careless mistake is run into handle, also can make loudspeaker send the sound, bring inconvenience to the user, and traditional way of taking in piston rod is that helicitic texture is set in the through hole of guide plate, when treating that piston rod is accommodated in the piston shell, the rotary-piston bar a few make the interior helicitic texture of piston rod and guide plate through hole cooperate fixing, though such structure setting can be accommodated in piston rod in the piston shell, being convenient to the user carries or places, but take in and when extracting piston rod, all need the rotary-piston bar a few, use extremely inconvenient.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of more convenient piston rod to take in or extract the portable manual piston type pneumatic loudspeaker of piston shell.
For achieving the above object, the utility model provides a kind of portable manual piston type pneumatic loudspeaker, comprise speaker body, piston shell, guide plate, speaker body is connected with the gas outlet of piston shell, constituting one between piston shell and the guide plate can be for the cavity volume of piston activity, guide plate is provided with through hole, be equipped with piston rod in the through hole of guide plate, one end of the piston rod in piston shell is provided with piston, the other end of the piston rod outside piston shell is provided with handle, be provided with the spring that makes piston reset in the piston shell, the end that piston rod is provided with this end of handle is the cylindrical boss that is rotatably assorted with the guide plate through hole, piston rod middle part between cylindrical boss and the piston is made of rectangular convex tendon, and the radially radius of cylindrical boss is less than the radial height of convex tendon, and described guide plate through hole is provided with the breach that cooperates with rectangular convex tendon slippage.
The beneficial effects of the utility model are: because piston rod is provided with the end of this end of handle is the cylindrical boss that is rotatably assorted with the guide plate through hole, piston rod middle part between cylindrical boss and the piston is made of rectangular convex tendon, and the radially radius of cylindrical boss is less than the radial height of convex tendon, described guide plate through hole is provided with the breach that cooperates with rectangular convex tendon slippage, so when being accommodated in piston rod in the piston shell, only need piston rod is compressed to the cylindrical boss position, rotary-piston bar certain angle a little again, allow rectangular convex tendon and guide plate through hole on the piston rod be provided with and the rectangular convex tendon breach mutual dislocation that cooperates of slippage mutually, just can realize the qualification that guide plate outwards stretches piston rod, when extracting piston rod outside the piston shell, only need to continue rotary-piston bar or reverse rotation piston rod, make the rectangular convex tendon on the piston rod corresponding with the breach on the guide plate through hole, just piston rod can be pulled out outside the piston shell, such structure is provided with simple in structure, and is easy to use.
The piston rod middle part that the utility model can further be set between described cylindrical boss and the piston is made of some rectangular convex tendon circumference uniform distributions, and described guide plate through hole is provided with several breach that are complementary with some rectangular convex tendons.
The utility model also can further be set to the opening part that described guide plate is contained in piston shell.
Guide plate is arranged on the opening part of piston shell, makes piston rod take in and extract all more convenient, also be convenient to the assembling of guide plate and piston shell simultaneously.
