Abstract
The invention discloses a rubber spring. The rubber spring comprises a main shaft, wherein a rubber layer is circumferentially fixed on the main shaft; and a cylindrical shell is fixedly sleeved out of the rubber layer. The rubber spring consists of three layers of structures and is provided with the main shaft, the rubber layer and the cylindrical shell sequentially from inside to outside, wherein the main shaft and the cylindrical shell are made of metal materials. When the rubber spring is used, two ends of the main shaft are connected with a backrest through a connecting rod; and when the backrest bends forward to apply a certain force to the main shaft to drive the main shaft to rotate a certain angle, the cylindrical shell of the rubber spring is fixed and immovable, so that the rubber layer generates a torque force through the rotation of the main shaft, the torque force is bigger when the rotation angle of the main shaft gets bigger, the main shaft and the backrest are driven by the torque force to reset, and the backrest can be adjusted by any angle.
Description
Technical field
The present invention relates to a kind of swivel chair accessory, the rubber spring that particularly a kind of swivel chair chassis is used.
Background technique
The swivel chair chassis is a vitals that is contained in swivel chair seat cushion below, the up-down of seat cushion, and the reclining angle adjustment of backrest all relies on the chassis to accomplish; In the existing technology; Can realize that in the chassis that the backrest reclining regulates all be to adopt metal spring as critical piece, not only have complex structure, shortcomings such as manufacture difficulty height; Can only realize the adjusting of limited several angles; And because people's height is different, everyone is also different to the impression of each angle comfort level of backrest, so can not satisfy proprietary needs.
Summary of the invention
The present invention has overcome above-mentioned deficiency of the prior art, provides a kind of simple in structure, can realize the rubber spring of arbitrarily angled adjusting, thereby can simplify the structure on chassis, practices thrift manufacture cost.
Technological scheme of the present invention is achieved in that
A kind of rubber spring comprises main shaft, on main shaft, circumferentially is fixed with rubber layer, is arranged with cylindrical outer casing at the rubber layer outer fixing.
As preferably, main shaft is the central axis setting along cylindrical outer casing.
In order to realize being connected,, on main shaft, be welded with a pair of lug as preferably with other parts of swivel chair chassis.
For conserve space, as preferably, described rubber layer, cylindrical outer casing are along being divided into two sections on the main shaft axial direction, and lug is welded on two sections main shafts between the cylindrical outer casing.
For fixing cylindrical outer casing,, on every section cylindrical outer casing, be provided with an engaging lug as preferably.
As preferably, the cross section outer contour shape of described rubber layer is circular.
As preferably, the both ends open of cylindrical outer casing.
Link to each other with backrest for ease, as preferably, the two ends of main shaft are exposed to outside the rubber layer.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
Rubber spring of the present invention is made up of three-decker, is provided with main shaft, rubber layer and cylindrical outer casing from inside to outside successively, and main shaft and cylindrical outer casing all are to be processed by metallic material; During application, the main shaft two ends are connected backrest through connecting rod, ought apply certain power to main shaft during the backrest reclining; Drive main spindle is rotated certain corner, and the cylindrical outer casing of rubber spring is fixed, so the rotation of main shaft makes rubber layer produce torsion; The corner of main shaft is big more; Torsion is big more, and this part torsion can order about main shaft and backrest resets, thereby makes backrest can realize regulating at any angle.
The present invention is provided with engaging lug on cylindrical outer casing, other parts link to each other in engaging lug and the chassis, have realized the cylindrical outer casing location, prevent that it from rotating.
Description of drawings
Fig. 1 is the structural representation of rubber spring in the embodiment of the invention;
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Embodiment of the present invention is following:
Embodiment: a kind of rubber spring like Fig. 1, shown in Figure 2, comprises the main shaft 3 in order to the connecting base chair backrest; Outside main shaft 3, circumferentially be fixed with rubber layer 4; The external frame of rubber layer 4 cross sections is circular, and the two ends of main shaft 3 are exposed to outside the rubber layer 4, are arranged with cylindrical outer casing 5 at rubber layer 4 outer fixing; The both ends open of cylindrical outer casing 5, main shaft 3 all is to be processed by metallic material with cylindrical outer casing 5.The course of working of rubber spring of the present invention is: main shaft 3 and cylindrical outer casing 5 are placed in the mould, and main shaft 3 is in the position of cylindrical outer casing 5 central axis, the rubber formation rubber layer 4 of between main shaft 3 and cylindrical outer casing 5, casting then.
Described rubber layer 4, cylindrical outer casing 5 are along being divided into two sections on the main shaft axial direction; Two sections cylindrical outer casings 5 do not link to each other; On every section cylindrical outer casing 5, be provided with an engaging lug 6; On engaging lug 6, be provided with axis hole 1, on the main shaft that exposes between two sections cylindrical outer casings 5, be welded with a pair of lug 15, on lug 15, be provided with axis hole 2 17.
When main shaft 3 rotates, cylindrical outer casing 5 is in fixed state, and the rotation of main shaft makes rubber layer 4 produce torsion, and the corner of main shaft is big more, and torsion is big more, and this part torsion can order about main shaft 4 and reset, thereby makes backrest can realize regulating at any angle.
Claims (5)
1. rubber spring; It is characterized in that: comprise main shaft, on main shaft, circumferentially be fixed with rubber layer, be arranged with cylindrical outer casing at the rubber layer outer fixing; On main shaft, be welded with a pair of lug; Described rubber layer, cylindrical outer casing are along being divided into two sections on the main shaft axial direction, lug is welded on two sections main shafts between the cylindrical outer casing, on every section cylindrical outer casing, is provided with an engaging lug.
2. a kind of rubber spring according to claim 1 is characterized in that: main shaft is the central axis setting along cylindrical outer casing.
