Problems solved by technology

Once the individual size of one of the parts of this valve locking mechanism does not fully meet the specifications, it will lose its locking effect, and after the locking mechanism has been in operation for a period of time, the protrusions on the tapered lock block will slowly wear out. To a certain extent, the lock block falls off, and the valve falls into the cylinder, so that the entire engine is scrapped and the loss is serious.

Embodiment Construction

[0007] The present invention will be further described below in conjunction with accompanying drawing.

[0008] Referring to Fig. 1, the multi-channel valve locking mechanism is provided with three rings 4 for locking on the small end of the valve stem 1, the rings 4 are integrally formed with the valve stem, and each ring is arranged at equal intervals On the small end of the valve. Correspondingly, there are three half-ring protrusions 3 equally spaced on the tapered locking block 2, so that the three half-ring protrusions 3 and the three rings 4 form multiple valve locking mechanisms for locking.

[0009] Because the present invention has multiple locking effects on the air valve, it has a good locking effect, and at the same time, its service time is greatly extended.

Abstract

This invention provides a valve retaining mechanism of a car engine including a valve rod and a taper gate piece matched to the small end of the rod, at least two loops are set in equal distance on the small end, there are at least two semi-ring humps matched with the valve on the taper gate piece, which can avoid loss of the locking caused by disqualification of the size of a traditional single valve retaining mechanism, and when a semi-ring hump is worn out, other ones can makeup it still so as to increase the locking quality of the retaining mechanism.

Description

technical field [0001] The invention relates to a valve locking mechanism, in particular to a valve locking mechanism for an engine. Background technique [0002] Usually, in order to ensure the normal opening and closing of the engine valves, a conical lock block is used on the engine to lock the valves. For the valve locking mechanism on the engine, the traditional single-ring track locking structure is adopted, that is, only one ring track is set on the valve, and a semi-circular protrusion is provided on the conical lock block to cooperate. Once the individual size of one of the parts of this valve locking mechanism does not fully meet the specifications, it will lose its locking effect, and after the locking mechanism has been in operation for a period of time, the protrusions on the tapered lock block will slowly wear out. To a certain extent, the lock block falls off, and the valve falls into the cylinder, so that the whole engine is scrapped and the loss is serious....
