The utility model discloses a set up a gasket that has circular lockhole, avoided the locking of traditional locking mechanism to wave the problem of waving that appears behind the arm.
Description
Technical field
This utility model relates to waving tricycle technical field, is specifically related to wave the retaining mechanism in rocking equipment in tricycle.
Background technology
The feature waving tricycle is to utilize rocking equipment to make its reduction centrifugal force that slopes inwardly when bicyclist turns round, and its advantage is to solve the problem easily turned on one's side when tricycle turns round.Existing rocking equipment generally includes a Swing Arm, and Swing Arm is connected to connecting tube rear, and locks Swing Arm by retaining mechanism, by locking or unblock rocking equipment, is turned on and off swing function.Retaining mechanism engages the locking realizing Swing Arm typically by an alignment pin with the lockhole on Swing Arm, in existing retaining mechanism, lockhole on Swing Arm is elongated waist-shaped hole, remains able to wave after locking, and such bicyclist especially old people can be very inconvenient when riding.
Utility model content
The applicant improves for disadvantages mentioned above of the prior art, it is provided that the retaining mechanism in the tricycle rocking equipment of a kind of reliable lock.
The technical solution of the utility model is as follows:
Retaining mechanism in tricycle rocking equipment, including positioning seat and Swing Arm, positioning seat is fixed in connecting tube rear end, positioning seat is provided with alignment pin, with elongated lockhole on Swing Arm, elongated lockhole is correspondingly arranged with alignment pin, positioning seat rear end is provided with installation axle, Swing Arm is worn on the mounting shaft and is rotatably supported on installation axle by bearing arrangement, axle axle head is installed and is provided with locking nut, Swing Arm is provided with on the sidewall of elongated lockhole and is connected with pad, pad is used for installing between the pin-and-hole of alignment pin and elongated lockhole on positioning seat, pad is with round keyhole, the centrage of round keyhole, the axis of alignment pin and the central axis of elongated lockhole are point-blank.
Its further technical scheme is:
Described pad is circular gasket.
Described Swing Arm is provided with the container installed surface of arc.
Technique effect of the present utility model:
This utility model is by having on elongated lockhole Swing Arm affixed one have the pad of round keyhole existing, the size of round keyhole matches with alignment pin external diameter, compared to traditional elongated lockhole, round keyhole is fitted with alignment pin outer wall, occur after preventing tradition retaining mechanism locking Swing Arm waves, it is ensured that the locking effect of Swing Arm.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model, and in figure, Swing Arm is locking state.
Fig. 2 is A portion enlarged drawing in Fig. 1.
Fig. 3 is the side-looking structural representation of pad described in the utility model.
Wherein: 1, positioning seat；11, axle is installed；2, Swing Arm；21, elongated lockhole；22, container installed surface；3, alignment pin；4, locking nut；5, pad；51, round keyhole；6, connecting tube.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described.
nullSee Fig. 1、Fig. 2、Fig. 3，This utility model includes positioning seat 1 and Swing Arm 2，Positioning seat 1 is fixed in connecting tube 6 rear end，Connecting tube 6 is the connecting tube in tricycle frame，Connecting tube 6 is connected with the middle pipe lower end in tricycle frame，Positioning seat 1 is provided with alignment pin 3，With elongated lockhole 21 on Swing Arm 2，Elongated lockhole 21 is correspondingly arranged with alignment pin 3，Positioning seat 1 rear end is provided with installation axle 11，Swing Arm 2 is set on installation axle 11 and is rotatably supported on installation axle 11 by bearing arrangement，Axle 11 axle head is installed and is provided with locking nut 4，Swing Arm 2 is provided with on the sidewall of elongated lockhole 21 and is connected with pad 5，Pad 5 is used for installing between the pin-and-hole of alignment pin 3 and elongated lockhole 21 on positioning seat 1，Pad 5 is with round keyhole 51，The centrage of round keyhole 51、The axis of alignment pin 3 and the central axis of elongated lockhole 21 are point-blank.
The preferably circular pad of pad 5.
Swing Arm 2 is provided with the container installed surface 22 of arc.
Time actually used, between locking nut 4 and Swing Arm 2 rear end, leave axial gap, it is simple to Swing Arm 2 is installing swing on axle 11.When rocking equipment is locked, alignment pin 3 is sequentially inserted into pad 5, Swing Arm 1, alignment pin 3 is combined successively with round keyhole 51, elongated lockhole 21, owing to the size of round keyhole 21 matches with the external diameter size of alignment pin 3, compared to being used alone of traditional Changxing lockhole 21, can preferably locking positioning pin 3, therefore ensure that the locking effect of Swing Arm 2.
Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model limited range sees claim, within protection domain of the present utility model, can make any type of amendment.
