Abstract

The utility model provides a swivel chair with a strong magnetic base. The utility model is composed of a chair seat, a vertical spindle, a shaft seat, support legs and permanent magnets respectively provided with a suction releasing device. The utility model is characterized in that the shaft seat extends at least three support legs which are uniformly distributed along a radial direction; the front end of each support leg is fixedly provided with the permanent magnet provided with the suction releasing device. When the swivel chair needs to be fixed, a turn knob is rotated, the permanent magnets provided with the suction releasing devices generate suction force and the swivel chair can be firmly fixed on a ferromagnetic steel deck of a ship. When the swivel chair needs to be moved, the turn knob is rotated, the suction force of the permanent magnets is released, the swivel chair is not adsorbed on the deck any longer, so the swivel chair can be moved. The utility model has the advantages of convenient use and simple structure.

Description

Strong magnetic force base swivel chair

The utility model relates to a kind of chair, particularly a kind of chair that the chair foot-rest combination of turning seat is arranged.

On existing boats and ships or warship, in order to adapt to sea going particular surroundings, be that the naval vessel is all ceaselessly waving under sail constantly, the oscillating motion that this orientation is indefinite, the equipment of putting on the requirement naval vessel, good fixing must be arranged, in order to avoid equipment is damaged in waving, or, it destroys other equipment because of moving turning over, this requirement also is identical to what be seen everywhere on the naval vessel with chair, for this reason, use chair on the naval vessel, need on the living conditions or instrument no matter be, the operation of equipment use chair, usually all be to adopt stationary structure, fixing mode is welded in hull, also useful bolt is in hull, but this arrangement, and each needs the place at seat, a chair all need be set, make this narrow naval vessel available space,, give to be in the people who works and live in crowded position for a long time because fixedly the setting of chair seems narrower and small, with extremely uncomfortable sensation, the chair that sets firmly can only be limited to set point and use, and also brings inconvenience for the user, a corresponding chair must be established in each position, also increases and acquires the quantity and weight of setting.For avoiding above-mentioned defective, adopt common displaceable chair, on the naval vessel, then bring the damage of chair again inevitably or destroy the contiguous equipment or the decoration of hull because of the movement and inclination of chair.

The purpose of this utility model is that a kind of strong magnetic force base swivel chair will be provided, and it can improve the environmental conditions in limited work living space, naval vessel, and is easy to use, alleviates weight of equipment.

Utility model is achieved in that on axle bed radial equipartition stretches to few 3 legs, sets firmly one at the front end of each leg and has the permanent magnet of removing suction device.

The knob of removing suction device is positioned at the inboard of magnet.

The magnetic force that the utility model utilizes magnet to produce, the ferromagnetic object that is in contact with it is firmly held, promptly be provided with the swivel chair leg of magnet, can firmly swivel chair be fixed on the steel deck, naval vessel, to adapt to the various demands of operating or living on the naval vessel, when needs are moved swivel chair, as long as stir the knob of removing suction device, magnet no longer includes suction, and swivel chair can break away from the steel deck and can move arbitrarily, can improve the work and the living environment of finite space on the naval vessel, and having the permanent magnet of removing suction device is existing product, can not increase the technical risk that swivel chair is made, its connection structure is also fairly simple, movable equipment, finite quantity equipment is fully used, can reduce number of devices, thereby alleviate weight of equipment, also be favourable factor to the naval vessel.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the strong magnetic force base of a utility model swivel chair axonometric drawing.

Fig. 2 is Fig. 1 textural association scheme drawing.

Fig. 3 is an A partial enlarged drawing among Fig. 2.

With reference to Fig. 1,2,3, strong magnetic force base swivel chair includes seat support 1, vertical axle 2, axle bed 3, leg 4 and has the permanent magnet 5 of removing suction device.

The below of seat support 1 sets firmly a vertical axle 2, vertical axle 2 is plugged in the centre hole of axle bed 3, vertical axle 2 can be rotated in the centre hole of axle bed 3, thereby constitutes the swivel chair structure that seat support 1 rotates, and still can make not only rotatable but also can regulate seat support 1 structure highly as required; The bottom of axle bed 3 forms the bigger hub portion 31 of a size, radial equipartition is stretched the leg 4 of establishing some supporting swivel chairs in axle bed 3 hub portions 31, the quantity of leg 4 is 3 to 6, in the overhanging portion foremost 41 of each leg 4, be provided with a cylinder 42, be provided with a screw 43 at the center of cylinder 42, cylinder 42 and leg 4 are made one.

One has the permanent magnet 5 of removing suction device, include double-screw bolt 51, spring washer 52, remove suction device 53 and magnet 54, be circular arc, square or other polygons around the magnet 54, double-screw bolt 51 and magnet 54 set firmly and are integral, have that the permanent magnet 5 mat double-screw bolts 51 of removing suction device screw in screws 43 and the leading section 41 that is fixed on leg 4, install a spring washer 52 in the middle of it, in order to prevent that double-screw bolt 51 from getting loose in screw 43, the baseplane of the magnet 54 of each leg 4 should be on the plane; Remove the inside of the main body 531 of suction device 53 at magnet 54; 532 sides of stretching in magnet 54 outward of its control dial; and be positioned at the inboard of magnet 54; promptly be positioned at the side of magnet 54 corresponding vertical axles 2; the turn to avoid 532 rounds uncontrolled collisions of knob; thereby cause the fixing unstable fault of swivel chair, also can protect not sensitive for damages of knob 532 simultaneously, and better appearance.

During use, swivel chair moved to needs the position is set, and the bottom surface that makes each permanent magnet 54 on the leg 4 is flattened on the deck level of ferromagnetics, each knob 532 of turn is to producing the suction position then, the deck adhesive that magnet 54 produces strong magnetic force and ferromagnetics, realize firmly with the fixing function above deck of swivel chair, when the swivel chair that will set firmly original position when needs moves to the another location, as long as each knob 532 of turn is to removing the suction position, magnet 54 suction with permanent magnet 5 of removing suction device disappear, and swivel chair can move easily.

The primary member of strong magnetic force base swivel chair can be made of metal, and also can adopt the reinforced plastics manufacturing, and it is applicable to all kinds naval vessels, boats and ships, also needs the various places of fixed seat applicable to having the ferrimagnetism floor.Simultaneously, this fixed form is not limited only to swivel chair, also applicable to the seat of other patterns.
