In figure：1 cylinder head, 2 catheter bodies, 3 through-holes, 4 blind holes, 5 fixation kits, 51 pressing sleeves, 52 lock sleeves, 53 hexagonal spiral shells
Cap, 54 first chamfering inclined-planes, 55 second chamfering inclined-planes, 56 rectangular channels, 57 pressure heads, 6 stop collars.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution：A kind of valve guide of internal combustion engine, including cylinder head 1, institute
Cylinder head 1 is stated equipped with blind hole 4, the bottom of the blind hole 4 is equipped with through-hole 3, is equipped with catheter body 2 in the through-hole 3, described
It is excessively to cooperate between catheter body 2 and through-hole 3, fixation kit 5, the inner wall of the fixation kit 5 is installed in the blind hole 4
It is excessively to cooperate between catheter body 2, the fixation kit 5 includes pressing sleeve 51 and lock sleeve 52, the lower end of the pressing sleeve 51
Internal orifice is equipped with the first chamfering inclined-plane 54, and first chamfering inclined-plane 54 is bonded with the second chamfering inclined-plane 55 of 52 upper end of lock sleeve,
The rectangular channel 56 of the lock sleeve 52 is formed separately several pressure heads 57, is threadedly coupled between the pressing sleeve 51 and blind hole 4, institute
State between lock sleeve 52 and blind hole 4 to be flexibly connected, the lock sleeve 52 is made using low-alloy steel Q345, it is ensured that pressure head 57 by
The raw flexible deformation of pressure can be restored.
