Abstract

The utility model discloses an umbrella-teeth shaped special floor nail, which is applicable for decorating and fixing a wooden floor and a composite floor. Umbrella-teeth shaped screw thread and a bullet shaped screw tip are arranged on a screw stem; a tool slot is arranged in a groove arranged at the end surface of a screw head; and the hole shrinkage is slightly thicker than the screw stem. The utility model overcomes the problems that the present wooden floor or the composite floor used for floor decoration can be easy to be broken off when being hammered by polish rods or twist steel nails, and the floor can loosen as the nails are off from the floor easily when people tread on the floor. The screw stem can be hammered in a floor base body or screwed in the floor base body mechanically, thereby being fast and convenient, stopping nail back and preventing nail off, so as to effectively avoid the floor loosening caused by the screw stem self-off due to treading or expansion on heating and contraction on cooling; meanwhile, the groove of the screw head can be filled with a putty that is in the same color with the floor, and the surface of the floor is flat, so as to realize the unified entity.

Description

The special-purpose flooring nail of umbrella thread form

Technical field the utility model relates to the special-purpose flooring nail of a kind of umbrella thread form, is used for the fixing wooden and composite floor board of finishing.

Background technique is present, people carry out ground surface finishing in family, market, hotel and other house places, when adopting wooden and composite floor board, it is fixed and is mostly directly to hammer into polished rod or fried dough twist steel nail, they are in fitment process, and directly hammering fractures easily and damages the floor, simultaneously along with people trample because of the floor elasticity or the reason of expanding with heat and contract with cold, can cause screw to withdraw from the generation of phenomenon naturally, make the floor very easily loosening.

Model utility content the purpose of this utility model is exactly at the problems referred to above, for people provide a kind of umbrella thread form special-purpose flooring nail, it is to be made up of the ailhead of sub warhead staple point, umbrella V-thread, Mi Zixing well on screw rod, can directly hammer into hammering or machinery screw-in floor.

The purpose of this utility model realizes by following technical measures:

Comprising screw rod, screw thread, screw head composition, is that umbrella V-thread and bullet-headed screw tip are arranged on screw rod, the slightly thick screw rod of undergauge, and its top is a screw head, end face is that well is arranged in groove.

Described well is a Mi Zixing.

Described screw tip angle is 55 °-75 °.

Advantage of the present utility model: 1, screw thread is the umbrella thread form on the screw rod, have quick, light nail or screw in all kinds of ground board substrate, simultaneously characteristics non-return, anti-retrogression are arranged again, avoid phenomenon generation because of trampling floor elasticity or expanding with heat and contract with cold and cause screw to withdraw from naturally.2,55 ° of-75 ° of sharp configuration are adopted in the screw tip, and are different with 45 ° of plain screw tips, and when effectively preventing to use hammering, the screw tip too sharply fractures or damages the floor.3, groove and well are reserved in the screw head position, the putty of being convenient to construct and being fit to the machinery screw-in and filling different colours,

Make whole floor color unanimity, surfacing, one integrated mass.

Description of drawings elaborates to the utility model below with reference to accompanying drawing:

Fig. 1 is that profile master of the present utility model looks schematic representation.

Fig. 2 is the schematic top plan view of the utility model Fig. 1.

Embodiment is by shown in Fig. 1,2, comprise screw rod (3), screw thread (4), screw head (1) composition, be that umbrella V-thread (4) and bullet-headed screw tip (5) are arranged on screw rod (3), this screw tip (5) machining angle is 60 ° of the bests, undergauge on the screw rod (2) slightly is coarser than screw rod (3) part, in undergauge (2) top is screw head (1), and end face is a groove, and Mi Zixing well (6) is arranged within it.
