Shoe cream room.Shoe cream room can be formed after the towing pin simple structure of the setting, pallet and the combination of towing pin body.
Further, first oil storage tank is less than second oil storage tank.The setting can slow down the loss speed of lubricating oil
Degree.
Further, the diameter with diameter greater than the oil outlet of the pallet oil filler point.The setting makes the speed of oiling
The speed fuel-displaced compared with block is slower.
Further, the towing pin body is further opened with towing pin oil filler point, and the towing pin oil filler point connection is described
Oil outlet and shoe cream room.The speed that lubricating oil is lost in the towing pin that the setting is further controlled.
Further, the towing pin oil filler point with diameter greater than the oil outlet, and less than the pallet oil filler point.Rank
The footpath mouthful that ladder type is successively decreased, keeps the smooth of circulation of the lubricating oil inside towing pin, slows down the speed of lubricating oil loss.
Further, the oil outlet is radially opened up along the towing pin body.Changing setting enables lubricating oil smoothly to flow out.
Further, the pallet oil filler point and the towing pin oil filler point are coaxially disposed.The setting keeps lubricating oil stream
Dynamic is unobstructed.
Compared to prior art, the wear-resisting towing pin top of oiling described in the utility model offers oil filler point, can be convenient
Ground to be added and be additionally provided with shoe cream room inside lubricating oil, and towing pin, and lubricating oil can be stored in towing pin body, by oil storage hole
Gradually flow out, can for a long time keep the degree of lubrication of towing pin, so that towing pin is more resistant, service life is longer.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of prior art towing pin；
Fig. 2 is the structural representation of the wear-resisting towing pin of oiling described in the utility model；
Fig. 3 is the three-dimensional exploded view of the wear-resisting towing pin of oiling described in the utility model.
Specific embodiment
As shown in Figures 2 and 3, Fig. 2 is the structural representation of the wear-resisting towing pin of oiling described in the utility model, and Fig. 3 is this
The three-dimensional exploded view of the wear-resisting towing pin of oiling described in utility model.A kind of wear-resisting towing pin of oiling, including pallet 1, towing pin sheet
If body 2 and bolt stem 3.The pallet 1 and towing pin body 2 respectively offer the screw worked in coordination, and are assembled by the bolt 3
Together, in the present embodiment, the pallet 1 and towing pin body 2 is each has eight screws, correspondingly, the utility model bag
