Abstract

A nail firmly wedged into a bearing object is characterized in that a nail cap is arranged at one end of the nail body, a V-shaped opening is formed at the other end, and a wedge-shaped block is in contact with the double inclined surface of the V-shaped opening. When being wedged into the bearing object, the nail has the functions as follows: due to the interaction of the acting force and the reacting force, the mutual squeezing effect is generated between the mutual contact of the wedge-shaped block and the V-shaped opening, and the mutual contact of the V-shaped opening and the bearing object, so that the nail can be firmly wedged into the bearing object and hard to pull out, and the using effect is effectively improved. The application range is wide, and the nail can be firmly wedged into the bearing objects such as walls, stones, iron blocks, etc.

Description

The nail in the object is born in a kind of firm wedging

Technical field

The utility model relates to a kind of nail, and the nail in the object is born in particularly a kind of firm wedging, and it can wedge hardness and bigger the bearing in the object of density such as body of wall, stone, iron block.

Background technique

Usually, the nail great majority of wedging in body of wall are iron nail or cement nail, and this kind nail is by the nail body, and the one end is connected with the head of a nail, and the other end has pointed nail point to constitute.Behind this iron nail wedging body of wall, because of with body of wall to combine soundness not good enough, be easy to be pulled out, influence the using effect of nail.And, this nail only be applicable to density and hardness less bear object such as body of wall or wooden object, for big the bearing object such as stone or iron block and then can't use of hardness, the application area of nail is restricted.

Summary of the invention

The purpose of this utility model is to provide a kind of firm wedging to bear the interior nail of object, it can overcome the deficiency of prior art, when bearing the wedging of this nail in the object, can be firm with bear object and combine, be difficult to be pulled out and, have good using effect.

Its solution is: an end of nail body is connected with the head of a nail, and the other end is provided with the V-type opening, is provided with the wedge type piece in the V-type opening, they the two between the double inclined plane contact connect.

When this nail is wedged when bearing in the object, in the V-type opening that is embedded in the nail body that the wedge type piece can be firm, the V-type opening end of nail body is when being subjected to the outside extruding force of wedge type piece, also be subjected to bearing the extruding force of the wedging hole wall in the object, under the mutual extrusion effect of this active force and reaction force, this nail can be born in the object in firm wedging, be difficult to be pulled out and, thereby can improve the using effect of nail effectively.Simultaneously, this nail not only can be wedged in the body of wall, can also wedge in stone, the iron block, has widened its application area.If during the bearing object and be wood materials of wedging, decide by situations such as the hardness of this wood materials and textures.

Description of drawings

Fig. 1 bears the structural representation plan view of the nail in the object for a kind of firm wedging.

Fig. 2 is the plan view of Fig. 1.

Fig. 3 is the side view of Fig. 1.

Embodiment

Among Fig. 1 to Fig. 3, there is the head of a nail 1 that is connected as a single entity with it upper end of nail body 2, and the lower end is provided with V-type opening 3, is double inclined plane between wedge type piece 4 and the V-type opening 3 and contacts and be connected, and leave the space between wedge type piece 4 and V-type opening 3 bottoms.Described nail body 2 is made by common carbon steel material with wedge type piece 4.

During use, bearing on the object after the boring earlier by means of drilling tool, to follow closely the end that body is connected with wedge type piece 4 again penetrates in the hole of being bored, and by means of hammer knock the nail body head of a nail end, the nail wedging is born in the object, wedge type piece 4 firm being embedded in the V-type opening 3 of following closely body of this moment, and wedging is born in the object firmly.

Claims

1, the nail in the object is born in a kind of firm wedging, comprises the nail body, it is characterized in that following closely body (2) one ends and is connected with the head of a nail (1), and the other end is provided with V-type opening (3), and the inclined-plane contact is connected with wedge type piece (4) in V-type opening (3).
