Platform 113 can pass through the stop projection 332 of connector 3.
Hereinbefore, boss 113 is formed in pin-and-hole, and alternatively, boss 113 can also be formed in through hole.
During installation：
1) first, referring to Fig. 9 and Figure 11, wear-resisting root 1, which is fixed on after bucket labial lamina, can install wear-resisting tip 2, will be resistance to
The chamber portion 21 in sharpening portion 2 is enclosed in the department of assembly 11 of wear-resisting root 1, chamber portion 21 and the just phase contract of department of assembly 11, now, wear-resisting
The pin-and-hole in portion 1 and the hole of wear-resisting tip 2 are in the tangent state of approximate concentric or inner circle, the first through hole 211 of wear-resisting tip 2 with it is resistance to
First pin-and-hole 111 of mill root 1 is corresponding, and the second through hole 212 of wear-resisting tip 2 is relative with the second pin-and-hole 112 of wear-resisting root 1
Should；Connector 3 is inserted into the pin-and-hole of wear-resisting root 1 and the through hole of wear-resisting tip 2, bearing pin main body 312 passes through wear-resisting tip 2
First through hole 211 enter wear-resisting root 1 the first pin-and-hole 111, be persistently inwardly inserted into, until cause wear-resisting root 1 boss
113 by the second slideway 315 on the bearing pin head 311 of connector 3, and now, boss 113 is entered in the first slideway 323,
In X-direction due to jump ring 33 jump ring main body 331 barrier effect, connector 3 can not continue deeper into shifting in the X-axis direction
It is dynamic；
2) then, referring to Figure 10 and Figure 12, toothed tool 4 will be torn open and insert or put dismounting clamping part 313 on connector 3,
The certain angle of rotary connector 3, now boss 113 to jump ring 33 apply pressure, cushion 32 cause jump ring 33 in the Y-axis direction
Produce certain elastic module so that boss 113, can be convex by the stop on connector 3 in the rotation process of connector 3
332 are played, until boss 113 is entered in the receiving area 324 of connector 3, and the end of bearing pin main body 312 then passes through wear-resisting root
1 the second pin-and-hole 112 enters the second through hole 212 of wear-resisting tip 2；Then, due to the elastic-restoring force of cushion 32, cushion
32 resiliences, stop that projection 332 can prevent the activity of boss 113 from (boss 113 being prevented to return to first in the Y-axis direction
In slideway 323), and the second end end wall 3142 and jump ring 33 of the groove 314 on bearing pin head 311 to boss 113 in the X-axis direction
There is restrictive function.Thus, connector 3 can not be movable in X-axis and Y direction, and wear-resistant components are in stable state, by means of
Tear toothed tool 4 open, this installation process becomes very comfortable.
After use after a while, wear-resisting tip 2 is worn, it is necessary to when changing, using tearing the rotary connector of toothed tool 4 open
3, direction of rotation during installation on the contrary, clearly rotation can be labeled with connector 3 with indicating, so that wear-resisting root 1
Boss 113 invert from the receiving area 324 of connector 3 and return to the first slideway 323, then from the second through hole 212 of wear-resisting tip 2
Touch connector 3 (applying active force on the axial direction of bearing pin 31), the first slideway that boss 113 is taken advantage of a situation by connector 3 in place
323 and second slideway 315, it is thus connected device 3 and is come off from wear-resistant components, tears the completion of tooth process open.
When excavating equipment works, digging force is acted on wear-resisting tip 2, and the wear-resisting transit chamber portion 21 of tip 2 is to excavating equipment
Conduction, the pin-and-hole of wear-resisting root 1 and the through hole of wear-resisting tip 2 are to be in concentric or tangent inner circle state in this case, by
It is less than pin-and-hole, clear size of opening in the radial dimension of connector 3, so connector 3 is in free state in pin-and-hole, through hole.When
Right irregular building stones also can produce shock from side to connector 3, but non-frontal shock dynamics is limited, bearing pin main body
312 have strong restriction effect to the boss 113 of wear-resisting root 1 with jump ring 33, and the side impact of building stones can not also make connector 3
Wear-resistant components are escaped, ensure that the security that connector 3 uses.Alternatively, connector can be flexible, now its radial ruler
It is very little to be more than pin-and-hole, the size of through hole.
Muddy water can enter when connector 3 uses, and by accumulating for a long time, muddy water can become hard, and in the market much connects
The reason for failure for connecing device 3 is all such, the present invention has taken into full account this case, by controlling the wear-resisting pin-and-hole of root 1 and company
Connecing the size of device 3 prevents the building stones of bulk from entering.Captured for a long time by the boss 113 of wear-resisting root 1 by accommodating area 324, then
The region that the intrusion of muddy water may be present is the second slideway 315 and the first slideway 323.Each part need not totally consider mud during installation
Water；After use after a while, when wear-resisting tip 2 is removed, although hard clod occupies the second slideway 315 and first and slided
Road 323, but another effect of the boss 113 of wear-resisting root 1 highlights again in demolishing process, that is, shearing mud
Block, connector 3 is touched at the second through hole 212 of wear-resisting tip 2 in the X-axis direction, now boss 113 there will be one to clod
Shear action, clod flow out along the second slideway 315 and the first slideway 323, and connector 3 and pin-and-hole, the size difference of through hole will
These clods crushed are mediated, demolishing process terminates.
Embodiment two
