Description

Reinforced lifting screw structure

This creation relates to a solenoid structure, and in particular to a reinforced lifting screw structure.

In the elevator, the lifting screw is often used to adjust the lifting height, and the conventional lifting screw structure is as shown in Fig. 1, which is composed of the outer tube 1 and the fixing nut 2 provided in the outer tube 1, the nut 2 The fixing manner is to form two card slots 3 on the inner side surface of the outer tube 1 by extruding the outer side of the outer tube 1 on both sides, and the two card slots 3 respectively support the metal pad behind the nut 2 in the outer tube 1. Sheet 4, thereby fixing the nut 2. The lifting screw structure mainly has the following disadvantages: when the elevator is subjected to an excessive load, the supporting force of the lifting screw is mainly concentrated on the two side card slots 3, and the card slot 3 is easily deformed by the force, thereby causing the metal gasket 4 to loose or The deformation will eventually cause the nut 2 to loosen, and even cause the nut of the nut 2 to be damaged or the nut 2 to be broken, so that the lift loses the lifting effect.

In view of this, the conventional lifting screw has been improved.

In order to solve the above problems, the present invention provides a reinforced lifting screw structure, which can greatly enhance the force of the lifting screw, prolong the service life of the nut, and greatly avoid the risk of the nut falling off when the table is subjected to excessive force.

To achieve the foregoing objectives, the present invention provides a reinforced lifting screw structure comprising: a ring gasket, an outer tube and a nut. Wherein the annular gasket has two sides, the outer tube has one end portion and an outer side surface, the nut has two end surfaces, and is disposed in one end of the outer tube, one end face of the nut abuts the end portion, and the nut The other end faces abut one side of the annular spacer. The outer side surface is pressed inwardly along the radial direction thereof to form at least three card slots, each of the card slots abutting against the other side of the annular gasket, and spot welding is respectively formed in each of the card slots to form a solder joint .

Thereby, a plurality of covering points are formed on the gasket to fix the gasket, which can better strengthen the utility, thereby effectively improving the force capacity of the lifting screw structure and prolonging the service life of the nut.

Detailed features of this creation will be described in the detailed description that follows. However, those of ordinary skill in the art should understand that the detailed description and specific embodiments of the present invention are intended to be illustrative only and not to limit the scope of the invention.

The technical contents and features of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figures 2 through 4, the present application provides a reinforced lifting screw structure 10 that includes an annular spacer 20, an outer tube 30, and a nut 40.

The annular gasket 20 has two side faces 22, 24, and the outer tube 30 has an end portion 32 and an outer side surface 34. The nut 40 has end faces 42, 44 and is disposed in one end of the outer tube 30. One end face 42 of the nut 40 The end 32 is abutted and the other end face 44 abuts against a side 22 of the annular spacer 20.

The outer side surface 34 of the outer tube 30 is pressed inwardly along the radial direction thereof to form at least three card slots 36. The card slots 36 are evenly distributed on the outer side surface 34 of the outer tube 30, and the respective card slots 36 are respectively abutted against the annular spacers. The other side 24 of the 20 is spot-welded in each of the card slots 36 to form a solder joint 38, wherein the end of the outer tube 30 The port of 32 is recessed in the axial direction thereof to form a catching portion 322, and the end surface 42 of the nut 40 is abutted against the engaging portion 322.

It should be noted that in the present embodiment, the annular spacer 20 is a metal spacer, and the number of the card slots 36 is preferably four, but the actual implementation of the present invention is not limited thereto.

Thereby, a plurality of card slots 36 are formed on the outer tube 30, a plurality of covering points are formed on the spacer 20, and the plurality of card slots 36 are evenly distributed on the outer side surface 34 of the outer tube 30, so that the nut 40 can be evenly stressed, and Each of the card slots 36 is provided with a solder joint 38 to fix the gasket 20, which can better reinforce the gasket 20 and the nut 40, thereby effectively improving the force of the screw 10 and prolonging the service life of the nut 40. .

It must be noted that the detailed descriptions of the above drawings are merely for the purpose of explaining the technical contents and features of the present invention. Anyone who has general knowledge in the field of creation is aware of this. After the technical content and characteristics of the creation, all kinds of simple modifications, substitutions or reductions of components are subject to the scope of the patent application disclosed below without departing from the spirit of the creation.
