Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only the utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of engine rocker of band brake boss, bag
Include wear-resisting contact 1, rocker arm bush 2, lubricant reservoir 3, braking insert 4, braking boss 5, regulating bolt 6, the first rocking arm 7, oil-feed
The 8, second rocking arm 9 of mouth, rocker arm shaft 10, holddown spring 11, brake 12, piston return spring 13 and return pin 14, rocker arm bush 2
Left side be provided with wear-resisting contact 1, and its right positions is fixed with regulating bolt 6, and the top of rocker arm bush 2 is connected with lubricating oil
Chamber 3, the inner side for braking boss 5 are provided with braking insert 4, and brake the depth of groove in boss 5 to be is screw thread in 12mm, groove
Shape, the mode of threaded connection guarantee that braking insert 4 does not fall out, and braking boss 5 and rocker arm bush 2 are braked convex for being welded to connect
Good stability when platform 5 works, the first rocking arm 7 are connected with each other with the second rocking arm 9 by brake 12, the first rocking arm 7 and second
The size of rocking arm 9 is identical, and the braking boss 5 in outside be same level, be convenient for switch type work, brake 12 it is upper
Lower two ends are connected with oil-in 8, and 9 right-hand member of the second rocking arm is fixed with rocker arm shaft 10, and the outside of rocker arm shaft 10 is provided with compression bullet
