Abstract
The utility model discloses a protective cylinder taper pin type combination bolt, which comprises a bolt sleeve, a taper pin and a bolt body; the middle part of the bolt sleeve is provided with a threaded hole, one side of the bolt sleeve is provided with a guide positioning groove, the middle part of the taper sleeve is provided with a taper hole matched with the taper pin, and one end of the taper sleeve is provided with a guide positioning convex ring matched with the guide positioning groove. The utility model discloses improving original bolt round pin for taper pin and bolt, making the cutting force in the positive, opposite direction act on the taper pin completely, and the bolt is only locking and guide effect as the center pin, and the clearance between the two separates the cutting force totally, and is consumed by the taper pin, has improved the bearing capacity of work piece, increase of service life shortens the change time, easily operation.
Description
Technical Field
The utility model relates to a connecting piece technical field specifically indicates a protect a section of thick bamboo taper pin formula combination bolt.
Background
The bolt in the existing market generally adopts 3 sets of combinations, and bolt cover, protects a section of thick bamboo, bolt, and the bolt plays the tight and round pin axle effect of round pin in the use, and when protecting a section of thick bamboo rotation, produced vibration and distortion power make the bolt receive torsional force, because screw thread and round pin axle are as an organic whole, cause the screw thread to damage easily, connect to lose efficacy or change the difficulty, increase the loss, influence the construction progress.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a protect a section of thick bamboo taper pin formula assembling bolt.
In order to solve the technical problem, the utility model provides a technical scheme is a protect a section of thick bamboo taper pin formula assembling bolt: the bolt comprises a bolt sleeve, a taper pin and a bolt body; the middle part of the bolt sleeve is provided with a threaded hole, one side of the bolt sleeve is provided with a guide positioning groove, the middle part of the taper sleeve is provided with a taper hole matched with the taper pin, and one end of the taper sleeve is provided with a guide positioning convex ring matched with the guide positioning groove.
As a refinement, the outer diameter of the bolt sleeve is the same as the outer diameter of the taper sleeve.
As an improvement, the length of the taper pin is smaller than the depth of the taper hole.
Compared with the prior art, the utility model the advantage lie in: the utility model discloses improving original bolt round pin for taper pin and bolt, making the cutting force in the positive, opposite direction act on the taper pin completely, and the bolt is only locking and guide effect as the center pin, and the clearance between the two separates the cutting force totally, and is consumed by the taper pin, has improved the bearing capacity of work piece, increase of service life shortens the change time, easily operation.

Detailed Description
The following will explain in detail a kind of protection tube taper pin type assembling bolt of the present invention with reference to the attached drawings.
With reference to the attached drawings 1-3, the protecting cylinder taper pin type combined bolt comprises a bolt sleeve 1, a taper sleeve 2, a taper pin 3 and a bolt body 4; the middle part of the bolt sleeve 1 is provided with a threaded hole 5, one side of the bolt sleeve 1 is provided with a guide positioning groove 6, the middle part of the taper sleeve 2 is provided with a taper hole 7 matched with the taper pin 3, and one end of the taper sleeve 2 is provided with a guide positioning convex ring 8 matched with the guide positioning groove 6.
The outer diameter of the bolt sleeve 1 is the same as that of the taper sleeve 2.
The length of the taper pin 3 is less than the depth of the taper hole 7.
The utility model discloses when concrete implementation, inlay the welding respectively with bolt housing 1, taper sleeve 2 and protect a corresponding position of public head and female head of a section of thick bamboo to inserting, with taper pin 3, bolt body 4 with the jump ring assembly together as whole, insert bolt housing 1, taper sleeve 2 to with 1 screw locking of bolt housing, reach the requirement of locking and being connected.
The utility model discloses improving original bolt round pin for taper pin and bolt, making the cutting force in the positive, opposite direction act on the taper pin completely, and the bolt is only locking and guide effect as the center pin, and the clearance between the two separates the cutting force totally, and is consumed by the taper pin, has improved the bearing capacity of work piece, increase of service life shortens the change time, easily operation.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
