Abstract

The utility model relates to a wall plug for fixing metal goods on the wall, which has a tubby structure, the outer wall of the wall plug is provided with protrusions such as strip shaped processes and short thorns, the bottom of the wall plug is provided with a bottom hole, the inner diameter of the bottom hole can be slightly smaller than the outer diameter of the tail segment of the metal handle of the goods to be fixed, the tail segment is minutely provided with pit grain, when the wall plug is sleeved with the metal handle, the outer diameter of the wall plug is slightly larger than the outer diameter of the metal handle. The utility model has the advantages of firm fixation when driven into the wall, not easily dropping off, and so on.

Description

The wall plug

Technical field

It is relevant that the utility model and building wall hammer into metal, particularly a kind of wall plug.

Background technique

Article with equivalent area are installed on building walls, often to use many to expanding nut and metallic screw, but expanding nut and metallic screw are because its working principle and structural reason, firm not enough in porthole, deviate from easily, particularly for the hook that only has single strut, iron sieve and so on article, it is just unlikely still to adopt expanding nut and metallic screw to install on metope, in other words, earlier simple article are fixed on the plate face, again this plate face is adopted many expanding nut and metallic screw are just installed to draw a snake and add feet to it a little, simple article fixedly become very complicated, even diminish original metope picture attractive in appearance, this loses more than gain.

Summary of the invention

The technical problems to be solved in the utility model is the defective that will overcome above-mentioned prior art, and a kind of wall plug is provided, and solves simple article and still is fixed on simply on the metope, makes wall plug and article fixed in porthole, is difficult for deviating from.

Technical solution of the present utility model is as follows: a kind of wall plug of the goods of fixing metal on the wall, it is characterized in that it has the tubular construction of inner core, and a bottom outlet is established at its end, and outer wall is provided with bar shaped projection and short thorn;

Said bar shaped projection and short thorn are provided with respectively on the outer wall of wall plug, and the axisymmetric relation of each self-forming;

Said two short thorns are upwards outwards holded up with 45 degree angles;

The internal diameter of said inner core should be slightly less than the slightly thin external diameter that is provided with the rear of cheating line of metal handle for the treatment of the fixing metal article, and after the wall plug sleeve was gone into metal handle, its external diameter slightly was coarser than the external diameter of this metal handle;

It is that PP glue is made by polypropylene.

Technique effect of the present utility model mainly is:

1. adopt polypropylene (PP) glue to make the wall plug, its cylinder body outer wall is provided with a little long strip projection and short thorn, and these protrusions can make the wall plug more firm after squeezing into porthole, are difficult for deviating from;

2. the internal diameter of the utility model wall plug is slightly less than the external diameter of rear that is provided with the hole line for the treatment of that the fixture metal handle is thinner, and after the wall plug sleeve gone into metal handle, the external diameter of wall plug slightly was coarser than this metal handle again, and its function is that itself and wall plug inwall are linked closely, and more difficultly deviates from;

Therefore the utility model wall plug to be particularly suitable for single strut article fixing on metope, make metope more clear attractive in appearance.

Embodiment

See also Fig. 1, Fig. 2, Fig. 3, the utility model wall plug 1 is the tubular construction with inner core 11,, there is bottom outlet 14 at its end, its outer wall is provided with bar shaped projection 13 and short thorn 12 protrusions such as grade, the purpose of protrusion setting is to make the wall plug more firm after squeezing into porthole, be difficult for deviating from, and how to be provided with not is to be most critical, from manufacturing process and angle attractive in appearance, Fig. 1, what Fig. 2 and Fig. 3 explained is the preferred embodiment of the utility model wall plug, and the short thorn 12 of two row is upwards outwards holded up with 45 degree angles, forms hangnail, this structure helps the wall plug is compressed into porthole, and is difficult for deviating from from porthole.

Fig. 4 is that the utility model wall plug 1 is inserted in the schematic representation of metal metal handle 2.The external diameter of the rear that is provided with hole line 21 that wherein metal handle 2 is slightly thin should be slightly larger than the internal diameter of wall plug 1 inner core 11, and after wall plug 1 was inserted in metal handle 2, its external diameter slightly was coarser than the external diameter of this metal handle, and the direction that hole line 21 is provided with also should help into, and is difficult for deviating from.

The using method of the utility model wall plug 1 comprises the following steps:

1. earlier wall plug 1 is inserted in need that pinup metal is for example linked up with, the rear (seeing Fig. 4, Fig. 5) of the metal handle 2 of iron sieve etc.;

2. metal handle 2 is connected wall plug 1 and squeeze into (referring to Fig. 5, Fig. 6) in the pre-drilled porthole 31 together, be about to metal and fixed on the wall solid and reliablely.

The above only is the preferred embodiment of the utility model wall plug, should not limit the utility model with this, and promptly the equalization of being done according to the utility model application such as changes and modifies, and all must belong to the protection domain of the utility model patent.

Claims
