阅读说明：本技术 一种固定孔销的圆倒尖 (Round inverted tip of fixed hole pin ) 是由 唐登巨 于 2019-03-18 设计创作，主要内容包括：本发明公开了一种固定孔销的圆倒尖,它的主体包括有倒尖头(1)、倒尖尖(2)、防退齿(3)的一体铁制倒尖,采用普通钢材经模具冲压成上端是倒尖头(1),下端是倒尖尖(2),中段是倒尖防退齿(3),倒尖头(1)有较强硬度让锤子把它钉进木头里,倒尖尖(2)在木头起开路的作用,倒尖的防退齿(3)有防止倒尖钉进木头里倒尖不倒退的作用,倒尖钉进销里使销没有收缩的余地了。(The invention discloses a round reversed point of a fixed hole pin, which comprises a reversed point (1), a reversed point (2) and an anti-withdrawal tooth (3) which are integrally made of iron, wherein common steel is punched into the reversed point (1) at the upper end through a die, the reversed point (2) at the lower end and the anti-withdrawal tooth (3) at the middle section, the reversed point (1) has high hardness to enable a hammer to nail the reversed point into a wood head, the reversed point (2) plays a role of opening a circuit on the wood, the anti-withdrawal tooth (3) with the reversed point has the function of preventing the reversed point from being nailed into the wood head and preventing the reversed point from being withdrawn, and the reversed point is nailed into the pin to enable the pin not to be retracted.)

1. The utility model provides a round point of fixed orifices round pin which characterized in that: the main body of the tooth-back-proof tooth comprises a back-off-tip (1), a back-off-tip (2) and an integrated iron back-off tip of a back-off-tip (3).

2. The rounded tip of a fixed orifice pin as defined in claim 1, wherein: the upper end of the common steel material punched by the die is the inverted tip (1), the lower end of the common steel material is the inverted tip (2), the middle section of the common steel material is the inverted tip anti-withdrawal tooth (3), the inverted tip (1) has strong hardness to allow the hammer to nail the inverted tip into wood, the inverted tip (2) plays a role in opening a way in wood, the inverted tip anti-withdrawal tooth (3) has a role in preventing the inverted tip nail from falling into the wood, and the inverted tip nail has no room for shrinkage when entering the pin.

Technical Field

The invention is applied to the fixing construction of the intelligent furniture with round holes and round pins.

Background

The intelligent furniture of steel-wood structure, the hole is steel, and the round pin is wood, and in the use of day long and night, the cold and hot change of weather, the degree of contraction size of hole round pin is different, and the hole will become flexible with the round pin and drop.

Disclosure of Invention

The invention aims to provide a round and sharp fixed hole pin which can ensure that a hole and a pin do not fall off after being fixed, is convenient to use and has low cost.

In order to achieve the purpose, the technical content of the invention is as follows: a round inverted point of a fixed hole pin comprises an inverted point head, an inverted point and an integrated iron inverted point for preventing tooth withdrawal.

The invention has the technical characteristics of simple structure, convenient use and convenience.

Drawings

Fig. 1 is a perspective view of the present invention.

In the figure: 1, 2 and 3, anti-back teeth.

Detailed Description

As shown in figure 1, the round inverted point of the fixing hole pin of the invention comprises an integrated iron inverted point of an inverted point 1, an inverted point 2 and an anti-back tooth 3.

The upper end of the common steel material is punched by a die to form the inverted tip 1, the lower end of the common steel material is the inverted tip 2, the middle section of the common steel material is the inverted tip anti-withdrawal tooth 3, the inverted tip 1 has strong hardness to allow a hammer to nail the inverted tip into wood, the inverted tip 2 plays a role in opening a way in the wood, the inverted tip anti-withdrawal tooth 3 has a role in preventing the inverted tip nail from entering the wood, the inverted tip does not withdraw, and the inverted tip nail has no room for contracting the pin when entering the pin. The defects of the prior art are overcome, and construction convenience is brought.
