Description

Umbrella head is followed closely

Technical field

This utility model is related to a kind of umbrella head nail.

Background technology

Nail is the conventional connector in wood processing technique field, for two wooden devices to be fixed together.It is existing Some nails include nail body and the head of a nail, and the head of a nail is lamellar, and its side is plane, and opposite side connects nail body, nail sheet Body is vertical with the head of a nail, when using, the nail tip of nail is placed on the device with connection, and with hammer the head of a nail is tapped, and nail is thrown into In timber, the connection of two wooden devices is realized.Wooden furniture etc., people often paint paint in timber product, Not only so that wooden fixture is more attractive, and the isolation with two is painted, nail is separated with air, prevent nail from giving birth to Rust.Existing nail is plane due to the one side that the head of a nail is used to tap, therefore, nail is ordered into after timber, and due to vertical nail is tapped The face of son is also plane, therefore the head of a nail of nail at most can only be with the surface of timber-work in identical plane, more When be nail the head of a nail be located at timber outside, with handss touch can significantly feel that nail is not ordered completely in timber, this Sample is difficult to all be painted covering when flour sand is painted on nail, or paints after paint, and the paint on nail is also easily scraped Fall, the rustless property of nail is poor.

The content of the invention

The purpose of this utility model is to provide a kind of umbrella head nail, and nail is in painting process is painted in solution prior art It is difficult to be painted and all covers or paint the technological deficiency being easily scraped.

To solve the above problems, technical solution adopted in the utility model is：A kind of umbrella head nail, including nail body And the head of a nail, described nail body one end is the head of a nail, and the other end is nail tip, described nail body be integrally formed with the head of a nail and Be mutually perpendicular, on the described head of a nail away from nail body one end it is central raised.Arrange on the head of a nail in this utility model Projection, during using nail, projection when tapping position on the head of a nail of hammer, because raised area is much smaller than the head of a nail Area, nail ordered into after timber, and in the raised surface with timber is generally aligned in the same plane, the remainder of the head of a nail is ordered completely Enter in timber, and a pit is formed between the head of a nail and timber of nail, when painting paint on timber, be filled in pit Paint, the position that nail is located at outside timber is all painted covering, favorable rust preventing effect.

Used as further improvement of the utility model, the side on the described head of a nail away from nail body is multiple inclined-planes, Multiple inclined-planes intersect at high spot.Multiple inclined-planes are set on the head of a nail in this utility model, it is on the one hand further to increase nail The volume of pit after ordering in timber, another aspect plane is more beneficial for paint and is attached on the head of a nail relative to cambered surface, prevents oil Paint is scraped.

Used as further improvement of the utility model, the quantity on described inclined-plane is four, and four described inclined-planes are along circle Circumferential direction is uniformly distributed.The quantity on inclined-plane is four in this utility model, manufactures the mould easy to manufacture of nail, another aspect phase It is bigger with the difference of cambered surface for more inclined-planes, the shape of the whole head of a nail, it is more beneficial for paint and is attached on the head of a nail.

Used as further improvement of the utility model, the one end on described nail body away from the head of a nail is provided with screw thread.This It is threaded on nail body in utility model, prevents from causing nail voluntarily because the friction between nail and timber is too small Coming off or only need to apply the power of very little separates just can connected wooden implements, further enhance the bonding strength of nail.

Further improve as of the present utility model, the part being threaded on described nail body is no less than nail The 2/3 of body total length.Screw thread accounts for the length of whole nail body more than or equal to 2/3rds in this utility model, nail and wood Friction between material is bigger, and the switching performance of nail is more preferable.

In sum, the beneficial effects of the utility model are：By change the nail head of a nail shape so that nail order into Leave between the head of a nail and timber after in timber for the pit of storage paint, enable nail to be all painted covering, strengthen The rustless property of nail.

Specific embodiment

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2, the umbrella head nail shown in Fig. 3, Fig. 4 and Fig. 5, including nail body 1 and the head of a nail 2, described nail The one end of body 1 is the head of a nail 2, and the other end is nail tip 3, and described nail body 1 is integrally formed with the head of a nail 2 and both mutually hang down Directly, on the described head of a nail 2 away from nail body 1 one end central raised 4.

Side on the described head of a nail 2 away from nail body 1 is multiple inclined-planes 5, and multiple inclined-planes 5 are intersected at raised 4；This The quantity on the preferred inclined-plane 5 of embodiment is four, and four described inclined-planes 5 are distributed uniformly and circumferentially.

To strengthen the friction between umbrella head nail of the present utility model and timber, prevent nail from deviating from from timber, it is described Nail body 1 on be provided with screw thread 6 away from one end of the head of a nail 2；6 portion is threaded on the preferred nail body 1 of the present embodiment Divide 2/3 no less than the total length of nail body 1.

When following closely using umbrella head of the present utility model, the projection 4 in this utility model is tapped with hammer, whole nail is ordered Enter in timber, because nail body 1 is provided with screw thread 6, increase the frictional force between nail body 1 and timber, nail will not Voluntarily come off from timber, after nail is ordered in timber, the projection 4 on the head of a nail 2 is located at same with the surface of timber In plane, remaining position of nail is all ordered in timber, one is formed between the head of a nail 2 of nail and timber and is with raised 4 The circular pit in the center of circle, in brush paint, is filled full paint in pit, the head of a nail coating of whole nail is painted, and makes nail Son completely cuts off completely air, and nail will not get rusty, the design on inclined-plane in this utility model, the design of the cambered surface that compares, and paint more holds Easily it is attached on the head of a nail 2 of nail.

What is be not specifically noted in all this utility model description is prior art or can by existing technology Realize, it should be appreciated that for those of ordinary skills, can according to the above description be improved or be converted, and All these modifications and variations should all belong to the protection domain of this utility model claims.
