Abstract
The utility model discloses a reinforced elevating spiral tube structure, which comprises an outer tube, a nut and an annular gasket, wherein the nut is arranged in one end of the outer tube; one end face of the nut is pressed against one end part of the outer tube, and the other end face of the nut is pressed against one side face of the annular gasket; at least three clamping grooves are formed on the outer side face of the outer tube by extruding inwards along a radial direction; each clamping groove is pressed against the other side face of the annular gasket respectively; a welding spot is formed in each clamping groove respectively by spot welding. According to the reinforced elevating spiral tube structure, a plurality of coating points are formed on the outer side face, and the coated clamping grooves are reinforced by spot welding, so that the stress capacity of an elevating spiral tube is increased greatly, the service life of the nut is prolonged, and the risk of nut fall due to excessive stress of a workbench and potential safety hazards caused by damage or fall of the nut are avoided to a large extent.
Description
Technical field
The utility model relates to a kind of solenoid structure, relates in particular to a kind of reinforced lifting solenoid structure.
Background technique
In lift, often can regulate adjustable height with lifting screwed pipe; and current used lifting solenoid structure as shown in Figure 1; it is comprised of outer tube 1 and the nut 2 being fixedly arranged in this outer tube; the means of fixation of its nut adopts the mode of both sides extruding outer tube outer side surface to extrude on the inner side surface of outer tube and forms two draw-in grooves 3; these two draw-in grooves 3 support respectively the annular gasket 4 below of nut that is positioned at outer tube, thus set screw nut.This kind of lifting solenoid structure mainly has following shortcoming: when lift bears super heavy burden, the suffered support force of lifting screwed pipe mainly concentrates on both sides draw-in groove, the stressed easy distortion of draw-in groove, thereby cause annular gasket to become flexible or distortion, finally can cause nut loosening, even cause the damage of nut thread or nut cracked, thereby make lift lose lift action.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of reinforced lifting solenoid structure, can greatly strengthen the stress-bearing capability of lifting screwed pipe, extends the working life of nut, and avoids greatly the stressed risk that nut comes off when excessive of worktable.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of reinforced lifting solenoid structure, comprise outer tube and be located at nut and the annular gasket in this outer tube one end, one end face of this nut pushes against described outer tube one Qie Qi other end, end and pushes against on described annular gasket one side, described outer tube outer side surface on along its radially inwardly extruding be formed with at least three draw-in grooves, this each draw-in groove pushes against respectively on the another side of described annular gasket, and in this each draw-in groove respectively spot welding form a solder joint.
As further improvement of the utility model, described draw-in groove is uniformly distributed on the outer side surface of described outer tube.
As further improvement of the utility model, described draw-in groove is four.
As further improvement of the utility model, described annular gasket is metallic shim.
As further improvement of the utility model, the structure that an end face of described nut pushes against described outer tube one end is: the port of described outer tube one end forms an inserted part to its axial direction indent, and an end face of described nut pushes against on this inserted part.
The beneficial effects of the utility model are: this reinforced lifting solenoid structure forms several coated points on outer side surface, and the draw-in groove place spot welding after coated is reinforced, thereby greatly strengthen the stress-bearing capability of lifting screwed pipe, extend the working life of nut, and avoid greatly the stressed risk that nut comes off when excessive of worktable, and damage or the caused potential safety hazard that comes off because of nut.
Accompanying drawing explanation
Fig. 1 is existing lifting solenoid structure schematic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the cut-away section structural representation of Fig. 2.
By reference to the accompanying drawings, make the following instructions:
1---outer tube 2---nut
3---draw-in groove 4---annular gasket
5---solder joint 11---inserted part
Embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
A kind of reinforced lifting solenoid structure, as Fig. 2, shown in 3, comprise outer tube 1 and be located at nut 2 and the annular gasket 4 in this outer tube one end, one end face of this nut pushes against described outer tube one Qie Qi other end, end and pushes against on described annular gasket one side, described outer tube outer side surface on along its radially inwardly extruding be formed with at least three draw-in grooves 3, this each draw-in groove pushes against respectively on the another side of described annular gasket, and spot welding forms a solder joint 5 respectively in this each draw-in groove, like this, on outer tube, form a plurality of draw-in grooves, annular gasket is formed to a plurality of coated points, and in each draw-in groove, add solder joint with stationary annular pad, thereby can play better reinforcement effect to annular gasket and nut, thereby effectively promote the stress-bearing capability of screwed pipe, extend the working life of nut,
Preferably, described draw-in groove is uniformly distributed on the outer side surface of described outer tube, so that nut is stressed evenly.
Preferably, described draw-in groove is four.
Preferably, described annular gasket is metallic shim.
Preferably, the structure that an end face of described nut pushes against described outer tube one end is: the port of described outer tube one end forms an inserted part 11 to its axial direction indent, and an end face of described nut pushes against on this inserted part.
