Abstract
The utility model relates to a screw lifting middle pipe which belongs to the furniture technical field and comprises a sheath, a screw, a nut and a nut fixing sheath and other parts. The utility model is characterized in that the nut is connected with a gasket by concave and convex or electric welding method, the heaves around the edge of the gasket are embedded with concave mouth of the sheath, which overcomes the shortcomings that the nut and the gasket revolve and go down and the sheath and the gasket revolve relatively.
Description
The utility model relates to screw lifting mechanism, belongs to furniture technical field.
Existing screw lifting mechanism is made up of screw rod and two parts of nut, early stage screw rod, the working process of nut, comprise operations such as founding, turner, not only require great effort but also costly, in the recent period, nut has steel pipe to dash a screw thread to make instead, and at plastics fixed cover of said steel pipe nut outside cover, nut fixed cover outside puts long overcoat again.This nut structure does not need founding, therefore have make simple, work efficiency is high, the low advantage of cost, but in practicality three kinds of bad phenomenon can appear, be to rotate between nut and the pad, nut can break away from fixed cover, also can rotate between pad and the overcoat, above-mentioned phenomenon can influence the lifting of swivel chair and the Security of seat support.
The purpose of this utility model provides a kind of characteristics that still can keep original saving of labor, economize this, can make between pad and nut and the overcoat again and can not rotate, and reaches in the new screw lifting that nut can not sink to manage.
The technical solution of the utility model is as follows:
In a kind of new screw lifting pipe comprise screw rod, nut, near the nut periphery establish the nut fixed cover, nut fixed cover outside is overlapped again by overcoat, assemble with concavo-convex or electric welding mode between the recess that it is characterized in that nut and the convex of lower levelling plate and be connected, it is chimeric fixing with the recess that puts outward that following square washer periphery is established projection, and propped up by the overcoat recess.
Technique effect of the present utility model:
1,, therefore still kept prior art saving of labor and economized advantage originally because the utility model nut and overcoat all adopt steel pipe to make, and the injection moulding of nut fixed cover is made, and has cancelled operations such as founding, turner.
2, nut and pad have carried out location technology, therefore overcome relative rotation and nut sinking defective between them.
3, because the pad periphery establish by projection, can with the chimeric location of the recess that puts outward, prevented to rotate between pad and the overcoat.
Description of drawings:
Fig. 1 is the utility model broken section structural drawing.
Fig. 2 is the front view of pad.
Fig. 3 is the right elevation of Fig. 2,
Fig. 4 is the nut perspective view.
Fig. 5 is the part schematic representation that is linked and packed.
Fig. 6 is that the another kind of stereochemical structure of nut is economized sketch map.
1 is that overcoat, 2 screw rods, 3 overcoat recesses, 4 nuts, 5 nut fixed cover muscle ribs, 6 nut fixed covers, 7 overcoat flange, 8 nuts are towards putting shoulder, 15 nut lower end shoulders on a screw thread, 9 nut recesses, 10 screw thread stops, 11 pads, 12 pad periphery projectioies, 13 pad convexes, the 14 nut fixed covers among the figure.
The utility model is described in further detail with reference to the accompanying drawings below:
Consult Fig. 1, pipe is made of overcoat (1), screw rod (2), nut (4), nut fixed cover (6) and pad (11) in the new screw lifting, overcoat is that hollow seamless steel pipe is made, overcoat top flange bag mouth (7) is pushed down nut fixed cover (6), nut (4) outside is close to Luo Dingtao (6), the built-in screw rod of nut (2), it can be along the upper and lower lifting of nut, screw thread stop (10) is established in the screw rod lower end, in case screw rod is because of the excessive nut that skids off that rises, so improved safety in utilization.The nut fixed cover is upper and lower to be established shoulder or only establishes shoulder (14) in the upper end.
Referring to Fig. 2, it is circular pad (11), place on the nut fixed cover (6), lower end or only be arranged on its lower end, place the pad of lower end to be propped up by overcoat recess (3), pad can not sunk, make nut can not break away from fixed cover (6) simultaneously and sink, pad hollow, establish in interior week convex (13) at least one, the recess (9) of this convex (13) and nut (4) is just in time chimeric, its effect: be to make between pad (11) and the nut can not rotate, simultaneously pad periphery side establish projection (12) at least one, this projection and the chimeric location of overcoat upper notch (3) make between overcoat and the pad and can not rotate.
Fig. 3 is the right elevation of Fig. 2 pad.
Fig. 4 represents the stereochemical structure of nut, and its adopts seamless steel pipe to make, Guan Shangshe dash a some screw thread (8), nut lower end (being the upper end in the diagram) establish recess (9) at least one.
Fig. 6 represents another kind of nut structure, and its end is established shoulder (15) and recess (9).
Fig. 5 represents the structure after nut (4), nut fixed cover (6) and pad (11) assembling.
The utility model is applicable to particularly swivel chair lifting field of furniture.
Claims (4)
1, in a kind of new screw lifting pipe comprise screw rod, nut, near the nut periphery establish the nut fixed cover, nut fixed cover outside is overlapped again by overcoat, assemble with concavo-convex or electric welding mode between the recess (9) that it is characterized in that nut and the convex (13) of lower levelling plate (11) and be connected, it is chimeric fixing with the recess (3) that puts outward that following square washer (11) periphery is established projection (12), and propped up by the overcoat recess.
2, by managing in the described new screw lifting of claim 1, it is characterized in that pad (11) periphery side establishes a projection (12) at least, establish a convex (13) interior week at least.
3, by managing in claim 1, the 2 described new screw liftings, it is characterized in that nut (4) one ends establish a recess (9) at least, perhaps nut one end is established shoulder (15) and recess (9).
4,, it is characterized in that also establishing pad above the nut fixed cover by managing in claim 1, the 2 described new screw liftings.
