Preferably, a toothed plate positioning table matched with the toothed plate is arranged in the adjusting sleeve.

Preferably, the adjusting sleeve is internally provided with an adjusting sleeve positioning spigot matched with the toothed plate positioning table for use.

Preferably, a plurality of concave platforms matched with the bosses for use are arranged in the inner cavity of the adjusting sleeve.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model reduces the size clearance between the upper lug boss of the toothed plate and the concave table of the adjusting sleeve by connecting the upper lug boss of the toothed plate with the T-shaped bolt, prevents the phenomenon that the toothed plate deflects when the cone crusher is used, and ensures that the toothed plate is more stable and is not easy to loosen;

2. the utility model discloses a single T type bolted connection makes the installation of whole locking mechanism more swift with the dismantlement, has saved staff's time and has reduced staff's working strength to its pinion rack is more stable with being connected of adjustment cover, is difficult for appearing the cracked phenomenon of locking mechanism.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, a locking mechanism for a fixed toothed plate of a cone crusher comprises an adjusting sleeve 1, a toothed plate 2 is arranged inside the adjusting sleeve 1, a plurality of bosses 7 are arranged on the surface of the toothed plate 2, a plurality of T-shaped bolts 3 are arranged on the surface of the toothed plate 2, the transverse ends of the T-shaped bolts 3 are clamped with the insides of the bosses 7, locking baffles 4 are sleeved on the surfaces of the vertical ends of the T-shaped bolts 3, disc springs 6 matched with the locking baffles 4 are sleeved on the surfaces of the vertical ends of the T-shaped bolts 3, nuts 5 matched with the disc springs 6 are in threaded connection with the vertical ends of the T-shaped bolts 3, the toothed plate is connected with the T-shaped bolts through the upper bosses, the size gap between the toothed plate bosses and the concave table of the adjusting sleeve is reduced, the phenomenon that the toothed plate is deviated in the use process of the cone crusher is prevented, the toothed plate connection is more stable and is not easy to loosen, and is connected, make whole locking mechanism installation and dismantlement more swift, saved staff's time and reduced staff's working strength to its pinion rack is more stable with being connected of adjustment cover, is difficult for appearing the cracked phenomenon of locking mechanism.
