The utility model discloses coordinate locking device to lock cramping the cover at overhead opening and the transverse groove of setting up of fastening, can be fine when locking device locks the opening part will cramp set is also locked together for it not only locks the convenience, locks effectually moreover, improves the bracket travelling comfort, increase of service life.
Description
Technical field
This utility model relates to the parts of a kind of chair or stool, particularly relates to a kind of foot-operated circle.
Background technology
The chair higher at a lot of seats or stool bottom, often arrange a foot-operated circle for people's leg rest；Existing foot-operated circle, typically all include fastener head, outer ring, banding set and locking nut, fastener head is enclosed within the gas bar of chair or stool, locking nut screwing makes banding set banding on gas bar, banding set is compressed by this kind of structure due to locking nut typically all single-point, and banding set stress is not very uniform, not only locks cumbersome, and affect gripping effect, thus affect leg rest comfortableness and service life.
Utility model content
This utility model is in order to solve defect and deficiency present in above-mentioned prior art, it is provided that one is not only locked conveniently, and locking effect is good, improves leg rest comfortableness, the foot-operated circle increased the service life.
The technical solution of the utility model: a kind of foot-operated circle, including outer ring, fastener head be arranged on the banding set inside fastener head, described fastener head bottom is provided with opening and coordinates two transverse grooves of opening, and described opening part is provided with locking device.
This utility model arranges opening and transverse groove on fastener head and locks banding set to lock device, banding set can well be locked while being locked by opening part by locking device the most together, it is made not only to lock conveniently, and locking effect is good, improve leg rest comfortableness, increase the service life.
Preferably, described locking device includes clamping screw and locking wrench, described opening part is provided with two locking lugs, and described locking lug is provided with the locking hole locking bolt, and described clamping screw front end is connected with locking wrench after the locking hole of two locking lugs.
This kind of structure makes it easy to operate, and reliable lock.
Preferably, described locking wrench includes hands tommy bar and locking head, and described locking head is hinged with the front end of clamping screw by bearing pin, and locking head wears the through hole eccentric setting of bearing pin.
Preferably, the shape of described locking wrench matches with the profile of fastener head, and the distance of locking head locking state through hole to locking lug is more than the distance of locking head releasing orientation through hole to locking lug；During locking, locking head holds out against locking lug.
This kind of structure is further such that its locking effect is good, and compact conformation, good looking appearance.
Preferably, two transverse groove lines centered by opening are symmetrical arranged, and the length of each transverse groove is less than the length of fastener head semi-circumference.
This kind of structure makes fastener head bottom be possible not only to lock and be deformed, and will not excessive deformation, it is ensured that its firmness.
Preferably, described outer ring is connected with upper connecting rod by three with fastener head, and described connecting rod one end is fixed on bottom outer ring, and the connecting rod other end is fixed on fastener head top.
This kind of structure makes its sound construction reliable.
This utility model arranges opening and transverse groove on fastener head and locks banding set to lock device, banding set can well be locked while being locked by opening part by locking device the most together, it is made not only to lock conveniently, and locking effect is good, improve leg rest comfortableness, increase the service life.

1. outer ring in figure, 2. fastener head, 3. banding set, 4. opening, 5. transverse groove, 6. locking lug, 7. clamping screw, 8. hands tommy bar, 9. locking head, 10. connecting rod, 11. bearing pins.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, but is not the restriction to this utility model protection domain.
As Figure 1-3, a kind of foot-operated circle, including outer ring 1, fastener head 2 be arranged on the banding set 3 inside fastener head 2, fastener head 2 bottom is provided with opening 4 and coordinates two transverse grooves 5 of opening 4, being provided with locking device at opening 4.Locking device includes clamping screw 7 and locking wrench, is provided with two locking lugs 6 at opening 4, and locking lug 6 is provided with the locking hole locking bolt 7, and clamping screw 7 front end is connected with locking wrench after the locking hole of two locking lugs 6.Locking wrench includes hands tommy bar 8 and locking head 9, and locking head 9 is hinged with the front end of clamping screw 7 by bearing pin 11, and locking head 9 wears the through hole eccentric setting of bearing pin 11.The shape of locking wrench matches with the profile of fastener head 2, and the distance of locking head 9 locking state through hole to locking lug 6 is more than the distance of locking head 9 releasing orientation through hole to locking lug 6；During locking, locking head 9 holds out against locking lug 6.Two transverse groove 5 lines centered by opening 4 are symmetrical arranged, and the length of each transverse groove 5 is less than the length of fastener head 2 semi-circumference.Outer ring 1 is connected by four connecting rods 10 with fastener head 2, and connecting rod 10 one end is fixed on bottom outer ring 1, and connecting rod 10 other end is fixed on fastener head 2 top.
During this utility model assembling, hands tommy bar pulls open, and fastener head is in releasing orientation, is first enclosed within by fastener head on the gas bar of chair or stool, after position is reserved, pulls hands tommy bar so that locking head slowly holds out against locking lug so that fastener head is in locking state.
This utility model arranges opening and transverse groove on fastener head and locks banding set to lock device, banding set can well be locked while being locked by opening part by locking device the most together, it is made not only to lock conveniently, and locking effect is good, improve leg rest comfortableness, increase the service life.
