Abstract

The utility model discloses a double-bowl bell with three-preventing function for bicycle. Two shafts are respectively riveted with two bell bowls. The shafts are fixed on a bell seat after being sheathed with the middle part of a bell bracket. Fixing screws for the bell seat and a handle are tightly screwed at the position of the bell seat. A cover plate and a fixing screw bolt for the cover plate are arranged on the bell seat. A moveable door is arranged in the hole of the fixing screw bolt for the cover plate and is controlled to open and close by the position of the bell seat and the relative position of the bell seat and the handle after being fixed.

Therefore, a theft preventing function is reached by multiple actions, a long time and a big target in dismounting the double-bowl bell with three-preventing function for bicycle.

Description

Double-bowl bell with three-preventing function for bicycle

The utility model belongs to field of mechanical technique, is a kind of for three anti-two bowl bells of using on the bicycle.

Technical background of the present utility model: before the utility model is made, retrieved domestic utility model patent communique.Do not see the patent application that disclosed bicycle bell structure and bicycle bell anti-theft arrangement are arranged.The two bowl of the bicycle that technical background of the present utility model has only been known for people bell technology, the bell dome of goa is to lean on thread connection with axle.The installation of bell dome is very convenient, dismantles also very conveniently, Just because of this, also is very easy to stolenly, and people had added an oversheath afterwards, protects the bowl hoop increasing by one at a distance of the certain space of bell dome, though the dismounting of bell dome is so not convenient.But because the screw of the bell seat back of the body exposes, steal the bell person only need one prevailing bottle opener or other are had the instrument of similar functions, within maximum tens seconds in several seconds, just can connect bell seat band bell dome and steal, protect that the bell hoop is also corresponding to lose its protective effect.

The purpose of this utility model is will provide a kind of not change people's the motor habit of ringing a bell, and the bell dome rotation is sent out on the basis of bell rule and the tinkle of bells and tonequality, thief-proof, the bell seat of collection bell dome thief-proof and dual thief-proof be three anti-two bowl bells of the interior fail-safe structure of one, eliminate trouble and loss that bicycle bell is had things stolen and brought to people.

Three anti-two bowl bells support two bowls by rotatable two bowl parts, and the bell frame partial sum that dials bell clapper is used for connecting with handlebar, and the bell seat part of installing fender guard and the mechanical attachment between them and control mechanism are formed.

Fig. 1 is the axle side scheme drawing of three anti-two bowl bells, and (1), (20) are the bell dome of captiveing joint with axle among the figure; (2) (21) are bell clapper; (3) be ratchet; (4), (22) are nut; (5) be ball; (6) be the pearl bowl; (7) be the handle of ringing a bell; (8) be spring hitch; (9) be spring; (10) be the bell seat; (11) be cover plate screws; (12) be dodge gate; (13) be spring bearing; (14) be roller; (15) be cover plate; (16) be the bell frame; (17), (18) are fix screw; (19) be coupling sleeve; (23) be radius stay; (24) be stay hook; (25) be the cover plate screws hole; (26) for connecting the hoop screw; (27) for connecting hoop; (28) be screw rod; (29) protect the bolt plate; (30) be the spill draw-in groove; (31) be positioning groove.

Fig. 2 is the part figure in addition of roller among Fig. 1 (14).

Fig. 3 is the part figure in addition of Fig. 1 medi-spring bearing (13),

Fig. 4 is the part figure in addition of Fig. 1 cover plate (15).

Fig. 5 is be hit by a bullet the in addition part figure of latch (8) of Fig. 1.

The purpose of this utility model is achieved in that the axle in the original design is designed to the length that is used to pass bell frame bearing on one side by ratchet that two axles of the weak point of another side change the original design bell dome and are fixing riveted joint with axle by thread connection.Bell dome (1) is set up bell clapper (2), nut (4), pearl bowl (6), ball (5), be inserted in bell frame bearing behind the ratchet (3), overlap upper joint sleeve (19) again, bell dome (20) is set up bell clapper (21), is inserted in adapter sleeve (19) behind the nut (22), tightens fix screw (17), (18) respectively from bell flap plate (15) position; Can unscrew (17), (18) respectively from bell flap plate (15) position easily during dismounting.After the cover plate that is provided with positioning groove (15) covered, the dismounting of bell dome was just very difficult, thereby solved the stolen problem of bell dome.

Bell seat (10) is fixedly connected with bell frame (16) among Fig. 1, the axle that spring bearing (13) is inserted in roller (14) penetrates four fixed orifices of bell frame (16) bottom in the middle of bell seat (10), (13) two four statures of spring bearing are slightly crooked, prevent to come off and fixing.

Basic structure when more than belonging to product export, before being installed in the bicycle handle bar, with hand roller (14) rotation is made radius stay (23) jack-up spring hitch (8), open the movable tank circuit of dodge gate (12), the bell body is turned over turnback, dodge gate (12) is that the smooth thin slice that has certain intensity more than two is opened cover plate screws hole (25) by gliding voluntarily, insert a little thing in position, dodge gate (12) the movable tank circuit bottom this moment, as matchstick, the scraps of paper etc. can, in order to avoid turn back dodge gate (12) SELF CL when coming at the bell body; After bell is placed on the handlebar, go into stay hook (24) with an end hook that connects hoop (27), after embracing handlebar, be tightened against after the other end penetrates with screw rod (28) and connect hoop screw (26), cover cover plate (15), penetrate cover plate screws (11) from cover plate screws hole (25), cover plate is tightened, the screw rod back of the body of screw rod (28) is stuck in the spill draw-in groove (30) at dodge gate (12) tank circuit middle part.Pull out the little thing that inserts this moment on dodge gate (12) tank circuit, dodge gate (12) is closed the cover plate screw hole voluntarily, reaches the thief-proof effect of bell seat, and bicycle bell promptly installs.

Whole three anti-two bowl bells externally are closed, as dismantling bell dome, bell seat, dodge gate (12) is opened, only way is to connect car band bell to turn over turnback, dodge gate (12) is opened, and side is squatted on the ground, perhaps inserts a little thing in the dodge gate tank circuit, car turned back to dismantle cover plate screws (11), could dismantle bell seat, bell dome after unloading lower cover (15).Because the action of tearing bell open is many, the time is long, target is big, the action abnormality of overturning etc., and the person of spiriting away, child's mischief has been prevented, and specializes in surreptitiously the bell person and also can be unwilling emits so for stealing a bell that risk drops.

As dodge gate (12) is opened, not to connect car band bell to turn over turnback, but bell is overturn 180 by force on handlebar, owing to be provided with roller (14) in bell seat inside, the bearing (13) of said roller (14) is for having the spring bearing of certain elastic force to the handlebar direction, when the relative position after bell and handlebar installation rotates the angle variation, the elastic force assurance roller (14) to the handlebar direction that spring bearing (13) is had rubs mutually with handlebar and does corresponding rotation, roller (14) is gone up set radius stay (23) and is rotated thereupon, the spring hitch (8) that prelocalization bar (23) jack-up is installed is rebounded by intensity of self and the elastic force that has to dodge gate tank circuit direction, tack the movable tank circuit upper part of dodge gate (12), even bell has rotated 180 degree on handlebar, dodge gate (12) also can't self-opening, thereby plays dual thief-proof effect.

Spring hitch (8) penetrates the bell seat from the bell frame, prevents that at bell seat edge the people is provided with and protects the bolt plate for stirring spring hitch (8), with the closed structure of protection in guaranteeing.
