JPS58101826A - Clamp of intake pipe for autobicycle - Google Patents

Abstract

PURPOSE:To always prevent turning movement of a pipe in no relation to a shape of a carburetor, by constituting the captioned clamp, which tightens the intake pipe to a discharge port of the carburetor, from a loop shaped band provided with both a tightening part and stopper groove in the internal peripheral face. CONSTITUTION:This clamp 11 is to tighten an intake pipe 41 and the main unit is constituted from a loop shaped band 21 consisting of a band main unit 23 and sliding element 25. Here erecting elements 27, 29 are formed respectively to external both end parts of the main unit 23, and a tightening part 35 comprising a tightening bolt 31 and nut 33 is provided in each element 27, 29. While the sliding element 25 is formed by folding its intermediate part toward the outside to a sectional shape squarely turned and opened with one end, and a stopper groove 43 is formed. Then the groove 43 of the band 21 is stopped to a stopper protruding stripe 45 of the pipe 41 to fit the clamp 11, and then the bolt 31 is tightened to unturnably tighten the pipe 41 to a discharge port of a carburetor.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an intake pipe clamp for a motorcycle that prevents rotation about the intake pipe.

As shown in FIG. 1, a motorcycle intake pipe clamp (hereinafter referred to as a clamp) 11 connects an intake hole (not shown) of an engine 15 provided in a motorcycle 13 to a carburetor 1.
? This prevents the intake air 119 that connects the engine from getting caught in the throttle link that is fastened to the exhaust port of the carburetor 1f,
In order to simplify the work of tightening the carburetor of the intake $19, the conventional clamp 11 has a loop-shaped band 2 to prevent rotation about the intake t19.
A U-shaped locking fitting 23 is spit welded to the carburetor 1, and rotation is prevented by locking this fitting 23 to the protrusions and recesses of the carburetor F. However, this conventional clamp 11
Different detent fittings 23 are required depending on the shape of the
In some cases, it was impossible to install the detent fitting 23.

An object of the present invention is to provide an intake pipe clamp for a motorcycle that can prevent rotation at all times regardless of the shape of the carburetor.

Hereinafter, an embodiment of this ball-starting ball will be described based on the drawings. In FIGS. 3 and 4, 21 is a loop-shaped band, which is composed of a band body 23 and a sliding piece 25.

Both ends of the band body 23 are individually bent to form vertical pieces 2'7 and 29, respectively. A fastening portion 35 consisting of a fastening pole 31 and a nut 33 is provided on the vertical piece 2'7.
A hole (not shown) is drilled in one of the vertical pieces 27.
33 is melted. The fastening bolt 31 is inserted into the bolt through hole of the other vertical piece 29 from the outside, and the vertical piece 2
It is screwed into the nut 33 of No.7. 37,37°37.3f is vertical piece 2? , 29 is a support piece for maintaining the strength of the band body 23, and is melted on both edges of the bent portion 39, 39' of the band body 23.

The sliding piece 25 is a prominent piece that tightens the clamp 11.
This is to prevent the intake pipe '41 made of synthetic 11 resin from swelling up between the openings 9 and 9, and is welded to the inner circumferential surface of the band body 23 near one bent portion s9. The intermediate portion of this sliding piece 25 is bent outward in a cross-sectional shape, and as a result, a lock 11143 is formed in the inner circumferential direction. This locking groove 43 has a clamp 1 on the g & trachea 41.
1, a locking protrusion 45 integrally molded with the intake pipe 41 engages with the intake pipe 41. Note that the locking groove 43 is located at m of the sliding piece 25.
Since the clamp 11 is provided from - to the other end, the clamp 11 can be fitted to the intake pipe 41 from either the front side or the back side.

Therefore, when tightening the intake pipe 41 to the carburetor 17, first check the intake! Intake at the tip of 41! The clamp 11 is fitted so that the locking protrusion 45 of the band 21 locks into the engagement groove 43 of the band 21, and the exhaust of the carburetor 17 is connected to the tip of the intake pipe 41! (not shown), the fastening bolt 31 of the clamp 11 is tightened to the nut 33.

As described above, this invention is an intake pipe clamp for a motorcycle consisting of a loop-shaped band having a fastening portion and a locking groove provided on the inner circumferential surface. Rotation can be prevented by engaging the locking protrusion of the intake pipe with the locking groove provided in the band. Since there is no need to protrude the carburetor, rotation can be prevented at all times regardless of the shape of the so-called carburetor. Therefore, the fastening portion of the clamp does not get caught on the throttle link, and the work of fastening the intake pipe to the carburetor is simplified.
