Description
Technical field:
The present invention relates to the mankind life article, relate in particular to furniture, the particularly feet of seat, concrete is a kind of improved supporting base of seat.
Background technology:
Seat in the office furniture as computer chair, executive chair, adopts star base.In the prior art, star base is the global formation manufacturing, the color of five adjutages is identical can not be changed, color is more single, be difficult to satisfy the collocation requirement of different color seat cushion,, certainly will involve bigger production change if change the color of star base, and being difficult to form specialized batch process the in batches, the user uses inconvenience, cost height.In addition, the castor of star base does not contain brake apparatus, can slide significantly after the collision of vacant seat chair, takes a seat for the user once more and brings inconvenience.
Summary of the invention:
The object of the present invention is to provide a kind of improved supporting base of seat, the adjutage that described this improved supporting base of seat will solve seat star base in the prior art can not change the technical problem that color, castor do not have brake apparatus.
This improved supporting base of seat of the present invention is made of center joint pin and five adjutages, described five adjutages are radial and are fixedly connected on the joint pin of center, the outer end downside of any one adjutage all is connected with castor, wherein, all be coated with a cover fillet on the end face of any one described adjutage, cover fillet is made by the elasticity macromolecular material, be provided with projection on the bottom surface of any one described cover fillet, be provided with at least two spill draw-in grooves in the end face of any one adjutage, described projection is connected with described spill draw-in groove interference fit, is provided with locking device on any one described castor.
Further, described spill draw-in groove is V-shaped, and described projection is dumbbell shaped along the length direction of described cover fillet, and the middle part of described projection cooperates with the spill draw-in groove.
Further, described castor is the weak foot wheel that is provided with locking device.
Operation principle of the present invention is: on adjutage top cover fillet is set, can changes the color of adjutage by the cover fillet of changing different colours; Establish spring in the weak foot wheel, reserve the space after spring was compressed when seat was stressed, castor thereby can move flexibly, after the people disseats then spring resile, make castor be difficult to move, the vacant seat chair original place of slipping away no longer easily.
The present invention compares with prior art, and its effect is actively with tangible.The present invention is provided with cover fillet on the adjutage top of improved supporting base of seat, can change the color of adjutage by the cover fillet of changing different colours, and cost is low, and is easy to use, and retaining mechanism is set in castor, the problem of having avoided the vacant seat chair to slide arbitrarily.
Description of drawings:
Fig. 1 is the structural representation of improved supporting base of seat of the present invention.
The specific embodiment:
Embodiment 1:
As shown in Figure 1, improved supporting base of seat 1 of the present invention, constitute by center joint pin 11 and five adjutages 12, described five adjutages 12 are radial and are fixedly connected on the center joint pin 11, the outer end downside of any one adjutage 12 all is connected with castor 2, wherein, all be coated with a cover fillet 3 on the end face of any one described adjutage 12, be provided with projection 31 on the bottom surface of any one described cover fillet 3, be provided with at least two spill draw-in grooves 121 in the end face of any one adjutage 12, described projection 31 is connected with described spill draw-in groove 121 interference fit.
Further, described spill draw-in groove 121 is V-shaped, and described projection 31 is dumbbell shaped along the length direction of described cover fillet 3, and the middle part of described projection 31 cooperates with spill draw-in groove 121.
Further, be provided with locking device (not drawing among the figure) on any one described castor 2.
Further, described castor 2 is the weak foot wheels 2 that are provided with locking device.
Further, described cover fillet 3 is made by the elasticity macromolecular material.
The operation principle of present embodiment is: on adjutage 12 tops cover fillet 3 is set, can changes the color of adjutage 12 by the cover fillet 3 of changing different colours; Establish spring in the weak foot wheel 2, reserve the space after spring was compressed when seat was stressed, castor 2 thereby can move flexibly, after the people disseats then spring resile, make castor 2 be difficult to mobile vacant seat chair, the original place of slipping away no longer easily.
Further, described cover fillet 3 is made by the elasticity macromolecular material.Cover fillet 33 colors are changeable, and change conveniently, not only satisfied the collocation requirement with various color seat cushions, and adapted to the demand of different clients different color, thereby brought pleasure of the senses for different customers, make and adopt the seat of product of the present invention to be easy to be accepted by client.
