Detailed description of the invention
Attached drawing 1 is the cross-sectional view on the utility model main view direction；
Attached drawing 2 is the explosive view of the utility model；
Attached drawing 3 is the explosive view of A structure in attached drawing 2.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
A kind of low noise castor as shown in attached drawing 1 to 3 includes support 1, Middle shaft assembly 2 and wheel 3；The Middle shaft assembly
2 and wheel 3 be rotatably connected respectively with support 1, and Middle shaft assembly 2 and the axis of wheel 3 are vertically arranged；
The Middle shaft assembly 2 includes middle shaft body 4, mandril 5 and control key 9；The middle shaft body 4 is cylindrical, hollow chamber
Body, the mandril 5 are set to inside middle shaft body 4.The control key 9 is bar.5 outer circle of the middle shaft body 4 and mandril
Column surface has the first through slot 10 and the second through slot 11；Second through slot 11 is kidney slot.First through slot 10 and second
The position of through slot 11 is opposite, and the control key 9 is fixed in the first through slot 10, and slides up and down in the second through slot 11.
The Middle shaft assembly 2 further includes split pin 18, and the split pin 18 is set to top and the control of the first through slot 10
Between the upper surface of key 9.The step of assembling control key 9 is as follows：Control key 9 is inserted into the first through slot 10, then by split pin
18 squeeze into the gap between the upper surface of control key 9 and the first through slot 10, and control key 9 is axially fixed at first by extruding and is led to
In slot 10.
It further include first bearing 7 and second bearing 8；The first bearing 7 and 8 inner ring of second bearing respectively with middle shaft body
4 external cylindrical surface is arranged connection, and the first bearing 7 and 8 outer ring of second bearing are connect with support 1.It is with particularly pointing out, it is conventional
Generally only design has a bearing to castor, and the castor noise using a bearing is big, and operation is unstable, thus the utility model adds
Dress is provided with second bearing 8.
The support 1 includes support body 12 and locking sub-assembly 13；The support body 12 is provided with shaft mounting hole 14,
The Middle shaft assembly 2 and locking sub-assembly 13 are coaxially connected in shaft mounting hole 14；The locking sub-assembly 13 is sheathed on axis
The external cylindrical surface of component 2.
The locking sub-assembly 13 includes buckshot pad 15, spring washer set 16 and universal spring washer 17, the buckshot pad 15, spring washer set
16 and universal spring washer 17 from top to bottom sequentially coaxially connect；The control key 9 cooperates when castor is kept straight on buckshot pad 15, described
Control key 9 cooperates in castor locking with universal spring washer 17.It is provided with fixing groove on the inner cylinder face of the shaft mounting hole 14, circle
Spring washer 15, spring washer set 16 and universal spring washer 17 are ring structure, are provided on buckshot pad 15 and the external cylindrical surface of universal spring washer 17
Retainingf key, buckshot pad 15 and universal spring washer 17 are carried out circumferentially fixed by the cooperation of retainingf key and fixing groove.
It can be seen from the above, locking sub-assembly 13 and the position of support 1 and wheel 3 are relatively fixed, control key 9 and Middle shaft assembly
2 position is relatively fixed.
Buckshot pad 15 is provided with single direction controlling slot, when the control key 9 is connect with direction controlling slot, Middle shaft assembly 2 with
The position of support 1 and wheel 3 is relatively fixed, and castor is unidirectionally kept straight on；When the control key 9 is rested in spring washer set 16, castor ten thousand
To；The upper surface circle of universal spring washer 17 shows several protrusions, when the control key 9 is slid between any two protrusion, in
Shaft assembly 2 and the position of support 1 and wheel 3 are relatively fixed, and castor swings locking.Due to universal 9 upper surface array of spring washer have it is more
A protrusion, so castor can be locked in circumferential multiple directions.
A kind of low noise castor further includes brake gear and driving device；The brake gear is set under Middle shaft assembly
Side, and be rotatably connected with support 1；The driving device is set to the top of support 1, and connects respectively with support 1 and mandril 5
