Description

A kind of Decorative screw

Technical field

The utility model relates to a kind of screw, especially a kind of Decorative screw.

Background technique

Along with the raising of people's living standard, the requirement for domestic environment is more and more higher.Screw, as a kind of conventional fastening piece, is widely used; But in a lot of situation, the screw due to excessive use, screw head can affect decorative effect.At present, market has also occurred some screws having decorative effect, but these product decoration effects are single, versatility is poor; Processing technology requires higher; Require stricter to Material selec-tion.

A patent No. is had to be the Chinese utility model patent of CN00215090.5 (notification number: CN2431434Y), disclose a kind of Decorative screw, screw is first fixed thread bush, and thread bush has outside thread, decorating cap has tapped hole, and decorating cap is threadedly attached on thread bush.The decorated sunshade lid of screw head.Shortcoming is after a period of time, and thread bush has loosening possibility, and when often going out to want to unload trim, thread bush one runs up, and is difficult to the situation of taking off trim.

A patent No. is had to be the Chinese utility model patent of CN201220534718.5 (notification number: CN203009515U), disclose a kind of Decorative screw, screw head processes screw thread, trim has corresponding stud or screw coordinate with it, thus trim is connected on screw head.Trim is covered on screw head.

Above-mentioned two kinds of patents have a common ground, and trim is all be threaded connection the head being fixed to screw, first use instrument after screw-driving, then assemble trim with hand during assembling, equally also trim can be screwed down with hand again.In some public arenas or the large place of some flows, some trim is often removed by the child of some fribbles or curiosity, leaves exposed screw head, always allows people feel under the weather.Just there is the defect of this type in two kinds of structural designs above.The occasion used in the open, adopts the trim be threaded to be easy to occur the retardance of screw corrosion and dust, causes trim not opened, often will destroy it, just can open target object.Cause the difficulty of maintenance.

Summary of the invention

Technical problem to be solved in the utility model is a kind of preferred version provided for prior art background.

The utility model solves the problems of the technologies described above adopted technological scheme: a kind of Decorative screw, comprises trim (1), screw (4), packing ring (3) and magnet (2).Trim (1), by the magnetic force of strong magnets (2), is connected on screw (4) or packing ring (3) securely.

Compared to the prior art the utility model has the advantage of: on concrete operating level, trim can not take off by direct hand, just can must be taken off by special tool.

The utility model flexible structure is changeable, and decorative effect is rich and varied, and do not have many restrictions to choosing of material, processing technology is simple.

Trim of the present utility model can not only be positioned at bead interior, and can surround outward packing ring and screw head, more can adapt to different decorative environment requirement.

Embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Figure 1 and Figure 2, it is the structural representation of first embodiment of the present utility model, trim (1) is fixed with iron plate (5) below or other can by the material of attraction, and means of fixation is bonding with mighty bond or other mode comparatively firmly connected.The edge flange of packing ring (3) forms groove.During assembling, with screw (4), packing ring (3) is fixed on target object, then magnet (2) is put into the groove of packing ring (3), finally trim (1) is placed on magnet (2); Under the effect of magnetic force, iron plate (5) joins same trim (1) together, by magnet (2) being adsorbed on screw (4) and packing ring (3) tightly.Because trim (1) is very little with the flange gap of packing ring (3), trim (1) is difficult to take out after putting into groove, only has and just can be taken out by special instrument.This makes product can be widely used in different occasion.

As shown in Figure 3, Figure 4, be second example structure schematic diagram of the present utility model, trim (1) is inner fluted, and trim (1) ferrous material or other can be formed by the materials processing of attraction.During assembling, with screw (4), packing ring (3) is fixed on target object; Then ring magnet (2) is enclosed within screw (4) head, trim (1) covers on screw (4) and packing ring (3).Under the effect of magnetic force, trim (1) will by being adsorbed on screw (4) and packing ring (3) tightly.

As can be seen from above two instantiations, trim (1) is not by the impact of material, mode of structure, concrete production technology.Trim (1) both can be the monolithic entity of single material, also can be the assembly parts of various material, multiple part, different process requirement and decorative effect.This has greatly enriched form and the content of decoration, and decorative effect is rich and varied.

Claims (4)

1. a Decorative screw, comprise trim (1), screw (4) and packing ring (3), it is characterized in that, also comprise magnet (2), trim (1), by the effect of the magnetic force of magnet (2), is attached on screw (4) or packing ring (3).

2. Decorative screw according to claim 1, is characterized in that, trim (1) is positioned at the inside grooves that packing ring (3) flange is formed.

3. Decorative screw according to claim 1, is characterized in that, screw (4) and packing ring (3) are positioned at the inside grooves that trim (1) is formed.

4. Decorative screw according to claim 1, is characterized in that, the assembly parts that trim (1) is made up of multiple part or single component.
