Description
Technical field
A kind of castor is the utility model is related to, particularly a kind of castor of more convenient maintenance.
Background technology
Existing castor generally includes roller body, transverse axis and support, and roller body is fixed on support by transverse axis, support
It is fixed on again on the bearing for needing to install castor.Castor with after a period of time, it is necessary to carry out note lubricating oil.Typically roller is torn open
Under, by lubrication oil drop to transverse axis and roller body connection is needed, reach the purpose of lubrication.This castor lubricating system compares
Trouble is, it is necessary to dismantle castor, and lubricating oil easily drops onto and ground is stain on ground, the mode of lubrication is not to facilitate very much.
The content of the invention
The purpose of this utility model is to provide a kind of castor of more convenient maintenance, the castor of this convenient maintenance, including
Roller body, support and transverse axis, the transverse axis pass through roller body center, and transverse axis both ends are fixed on support, wherein, the rolling
Wheel body central is provided with through hole, and bearing is arranged with through hole, and transverse axis is set in Bearing inner and is fitted close with bearing medial surface；
Oiling groove is provided with inside the transverse axis, oiling groove one end communicates with the pouring orifice of transverse axis end, the oiling groove other end and bearing phase
It is logical.
Further, the oiling groove is L-type.Lubricating oil enters from one end of oiling groove, is flowed out from the oiling groove other end,
Enter at bearing and be lubricated.
Further, the oiling groove is T-shaped.Lubricating oil enters from T-shaped one end, flows out, enters from T-shaped both ends
It is lubricated at bearing, lubricating efficiency is higher.
Further, the pouring orifice is provided with the plug being adapted, it is necessary to dismantle plug when lubricating, and oiling is filled in after terminating
Upper plug head, prevent outflow of lubrication oil from staiing ground.
Further, the transverse axis is a nut bolt, and nut bolt includes hold-doun nut and movable nut, the oiling
Mouth is located at hold-doun nut end, and movable nut is used to transverse axis being locked at support.
Further, the roller body is provided with the convex surface protruded to both sides close to through hole, the height on the convex surface from
Become larger again close to through hole to tapering into away from through hole, during to close to roller body outer.
The castor of this convenient maintenance of the utility model compared with prior art, has the following advantages that：
1. castor is provided with oiling groove, oiling groove one end communicates with transverse axis end, and the other end is communicated with bearing, it is necessary to oiling
When, lubricating oil is injected from pouring orifice, lubricating oil is left at bearing by oiling groove, and oiling mode is simple, without castor is torn open
Under.Coordinate plug, can prevent outflow of lubrication oil from staiing ground.After plug is blocked, castor is rolled, and lubricating oil can be more
Comprehensive lubrication bearing.
2. oiling groove can be L-type or T-shaped, convenient to lead to lubricating oil at bearing at pouring orifice.
3. roller body is provided with the convex surface protruded to both sides close to through hole, the height on convex surface from close to through hole to remote
Taper into, become larger again during to close to roller body outer, this structure can not only save roller body from through hole
Raw material, and structural stability it is convenient than prior art by increasing the stronger of reinforcement.
Brief description of the drawings

Fig. 2 is the structural representation of roller body 1 of the present utility model；
Fig. 3 is the utility model right view（The part of transverse axis 3 is sectional view）；
Fig. 4 is the schematic diagram of transverse axis 3 of the utility model embodiment one；
Fig. 5 is the schematic diagram of transverse axis 3 of the utility model embodiment two.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one：
Referring to the drawings 1 ~ 4, the castor of this convenient maintenance, including roller body 1, support 2 and transverse axis 3, the transverse axis 3 are worn
The center of roller body 1 is crossed, the both ends of transverse axis 3 are fixed on support 2, and the center of roller body 1 is provided with through hole 4, and axle is arranged with through hole 4
5 are held, transverse axis 3 is set in the inside of bearing 5 and is fitted close with the medial surface of bearing 5；The inside of transverse axis 3 is provided with oiling groove 31, oiling groove
31 one end communicate with the pouring orifice 32 of transverse axis end, and the other end of oiling groove 31 communicates with bearing 5.
Roller body 1 is provided with the convex surface 6 protruded to both sides at through hole 4, and the height on the convex surface 6 is from close to through hole 4
Place becomes larger again to away from tapering at through hole 4, during to close to 1 outer of roller body, and on convex surface 6, height diminishes again gradual
The changeover portion for becoming big forms groove 7, therefore roller body 1 forms the shape and structure with convex surface 6 and groove 7.This structure
Relatively complete solid structure more saves material, test indicate that, this roller body structural stability is stronger.
In the present embodiment, oiling groove 31 is T-shaped, and pouring orifice 32 is provided with the plug 33 being adapted.By plug when needing oiling
33 open, and after lubricating oil is injected into oiling groove 31, then, prevent lubricating oil from dropping onto on ground by plug 33 beyond the Great Wall.
In the present embodiment, transverse axis 3 is a nut bolt, and nut bolt includes hold-doun nut 34 and movable nut 35, described
Pouring orifice 32 is located at the end of hold-doun nut 34, and movable nut 35 is used to transverse axis being locked at support 2.During actual installation, by horizontal stroke
Axle 3 is passed through from support, is then passed through in bearing 5, is passed from another support, and transverse axis 3 is fixed on into branch with movable nut 35
On frame 2, then mounted castor is fixed on bearing 8, completes the installation of castor., will when castor needs to add lubricating oil
Plug 33 is removed, and lubricating oil is injected from pouring orifice 33, then, prevent lubricating oil from dripping by plug beyond the Great Wall.When castor starts to roll,
Lubricating oil is flowed on bearing from oiling groove 31, reaches lubricant effect.
Embodiment two：
Referring to the drawings 5, the difference of embodiment two and embodiment one is that oiling groove 31 is L-type.The shape of oiling groove 31 is unlimited
It is set to T-shaped or L-type or the curved groove with radian.
In summary, preferred embodiment of the present utility model is these are only, is not intended to limit of the present utility model
Protection domain.All made within spirit of the present utility model and principle any modification, equivalent substitution and improvements etc., all should be wrapped
It is contained within the scope of protection of the utility model.
