Abstract

Firing pin formula wall body rivet, including nail pole and lance, the nail pole comprises upper portion nail pole and lower part nail pole, and upper portion nail peak of the staff portion sets up the head of a nail, and inside the inside and head of a nail of upper portion nail pole was arranged in to lance inslot, the lance imbedded to the lance groove in, and the lower part is followed closely the pole and is formed by the combination of the split type nail pole of a plurality of. The utility model discloses a form firing pin formula structure at the built -in lance of nail pole, during the split type nail pole radiating type embedding wall body of pole can be followed closely with the lower part to the lance, improved the joint strength of rivet and wall body greatly, have reasonable in design, convenient to use and firm in connection's advantage, but the wide application is in building, car, rail vehicle, electric and furniture trade.

Description

Firing pin type body of wall rivet

Technical field

The utility model is related to securing member is connected technical field and in particular to a kind of firing pin type body of wall rivet.

Background technology

In the connection of nonmetallic thin plate, such as wall body structure is general to select 6 grades of nuts to connect, between nonmetallic thin plate On-link mode (OLM) is rough, and difficulty is big, is also unable to machining internal thread, its bonding strength does not much reach ideal value yet.Due to nonmetallic The restriction of the various performances of connected material, nor be attached fixing using common pulling rivet, and, nonmetallic thin plate Require surface can not have ridge after connection, so the connection of nonmetallic thin plate is always a difficult problem.

Utility model content

The utility model provides a kind of firing pin type body of wall rivet, to solve the low discomfort of bonding strength that existing rivet exists Close the problem that nonmetallic materials connect.

The utility model solves its technical problem and be employed technical scheme comprise that：

A kind of firing pin type body of wall rivet, including nail rod and lance, nail rod is made up of top nail rod and bottom nail rod, and top is followed closely Masthead portion arranges the head of a nail, and a lance groove is built in inside top nail rod inside and the head of a nail, and lance is embedded in lance groove, bottom Nail rod is combined into by several split type nail rods.

Above-mentioned top nail rod bottom is threaded.

When the utility model uses, using rivet driver, nail rod is hammered into body of wall, then hit by clashing into head of a nail top Lance in bar groove, lance impacts bottom nail rod and dissipates, thus opening the split type nail rod of bottom nail rod, the body of wall being embedded in surrounding In.

The utility model passes through to form firing pin type structure in the built-in lance of nail rod, and lance can be by the split type nail of bottom nail rod Bar divergence expression embeds in body of wall, substantially increases the bonding strength of rivet and body of wall, has reasonable in design, easy to use and connects Firm advantage, can be widely applied to building, automobile, rail vehicle, in electric and furniture industry.

Brief description

With reference to the accompanying drawings and examples the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model；

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

Fig. 3 is the schematic cross-section of the utility model bottom nail rod；

Fig. 4 is use state schematic diagram of the present utility model.

In figure 1 top nail rod, 2 bottom nail rods, 3 lances, 4 heads of a nail, 5 screw threads, 21 split type nail rods, 41 lance grooves.

Specific embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4：A kind of firing pin type body of wall rivet, including nail rod and lance 3, nail rod is by top Nail rod 1 and bottom nail rod 2 form, and top nail rod 1 top arranges the head of a nail 4, lance groove 41 be built in top nail rod 1 internal and Inside the head of a nail 4, lance 3 is embedded in lance groove 41, and bottom nail rod 2 is combined into by several split type nail rods 21, and top is followed closely Bar 1 bottom is threaded 5.

When the utility model uses, using rivet driver, nail rod is hammered into body of wall, then hit by clashing into head of a nail top Lance in bar groove, lance impacts bottom nail rod and dissipates, thus opening the split type nail rod of bottom nail rod, the body of wall being embedded in surrounding In.

The utility model passes through to form firing pin type structure in the built-in lance of nail rod, and lance can be by the split type nail of bottom nail rod Bar divergence expression embeds in body of wall, substantially increases the bonding strength of rivet and body of wall, has reasonable in design, easy to use and connects Firm advantage, can be widely applied to building, automobile, rail vehicle, in electric and furniture industry.
