Abstract

The utility model provides a decorating screw which comprises a decorating cover (1), a screw (2) and a gasket (3). The decorating screw is characterized in that a screw head is provided with threads, the decorating cover (1) and the screw (2) are connected in a threaded mode, the threads on the screw head are threaded holes (21) on the screw head or outer threads (22) of the column-shaped screw head, and the decorating cover is provided with a threaded column (11) or a threaded hole (12) matched with the screw head.

Description

A kind of Decorative screw

Technical field

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

Background technique

Screw is one of the most frequently used fastening piece, but very not attractive in appearance at the exposed screw head of some occasion; Therefore on market, diversified Decorative screw has appearred.Wherein the patent No. is the disclosed patent working scheme of Chinese utility model patent of ZL00215090.5 (notification number is CN2431434Y), includes screw, thread bush, decorating cap.The Decorative screw that above-mentioned patent is related, owing to having used thread bush, trim is relatively outstanding, and the trim pattern is comparatively dull; Very large in the coupling mechanism force requirement, the shape of screw head has in the situation of particular requirement, seems helpless.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of preferred version for existing background technique.

The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of Decorative screw comprises trim (1), screw (2), packing ring (3); It is characterized in that being processed with on screw head screw thread, trim (1) and screw (2) are linked together with thread forms.

Screw thread on above-mentioned screw head can be according to multi-form screw, and selection is to process outside thread (22) on tapping hole (21) or column screw head on screw head, to reach best assembling effect.

Screw column on above-mentioned trim (11) or tapped hole (12) are that the scyewed joint form with screw head matches, and make trim and screw attachment solid and reliable.

Compared to the prior art the utility model has the advantage of: because different situations screw used can change, this programme all is suitable for for multi-form screw; The trim of difformity and unlike material be can satisfy simultaneously, decorative effect and content enriched.

Embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Figure 3, it is the first example structure schematic diagram of model utility, the cross recess center tapping (21) of screw head (2), there is double-screw bolt (11) inside of trim (1), the packing ring endoporus is tapered hole (31), screw head (2) end face can be concordant with packing ring (3) end face, and after screw (2) was urgent, trim (1) was assembled on screw (2).The height of trim (1) reduces greatly.

As Fig. 4, Fig. 5, shown in Figure 6, be second example structure schematic diagram of model utility, column screw head (2) external threading (22).Screw head in embodiment (2) is cross recess, also can be interior hexagonal or other form.Tapped hole (12) is arranged in trim (1), after screw (2) is in place, refills equipped decorative cover (1) and tighten.

As Fig. 7, Fig. 8, shown in Figure 9, be the 3rd example structure schematic diagram of the present utility model, there is double-screw bolt (11) in tapping hole (21) in the middle of screw head (2) in trim (1).This kind situation is used in the lock power situation that Assembly part will be very large, and screw head must be outer-hexagonal or other shape, to guarantee that screw is applied very large torsion, satisfies matching requirements.

Claims

1. a Decorative screw, comprise trim (1), screw (2), packing ring (3); It is characterized in that being processed with on screw head screw thread, trim (1) and screw (2) are linked together with thread forms.

2. Decorative screw according to claim 1, is characterized in that the screw thread on described screw head, refers to process outside thread (22) on tapped hole (21) or column screw head processing on screw head.

3. Decorative screw according to claim 1, is characterized in that having on described trim the screw column (11) or the tapped hole (12) that match with screw head.
