Abstract

The utility model discloses a connecting pin, which aims to provide a connecting pin that has a simple structure, a reliable connection, convenient assembly and invisible outer surface and can be produced in large quantities and standardization. The utility model is composed of a cylindrical pin sheath whose two ends are provided with a circular hole and a pin shaft that is respectively arranged in the circular hole and interference matched with the circular hole. The pin shaft is cylindrical or conical. The utility model has the advantages of simple structure, convenient manufacture and use, reliable connection, high intensity and nice outline, which is suitable for connecting different materials.

Description

A kind of connecting pin

Technical field

The utility model relates to link, particularly is used for a kind of connecting pin that connects between the entity component goods such as timber, plastics, cement, steel part.

Background technique

At the processing manufacturing industry of building industry, product, often can use two or above part are coupled together.Traditional link is a lot of, and they mostly require to be fixed with instrument at the end face of link as wood screw, iron nail, assembly nail, bolt, screw, tapping screw, swell fixture etc., and this can influence the attractive in appearance of object.

The model utility content

The utility model has overcome the deficiency of above-mentioned existence, provide a kind of manufacturing simple, connect reliably, easy to assembly, outer surface loses, and can carry out a kind of connecting pin of in enormous quantities and standardized production.

In order to address the above problem, the utility model is realized by the following method: it comprise two ends be shaped on the columniform guide of circular port and be installed in respectively in the circular port and with the bearing pin of its interference fit, described bearing pin is cylindrical or conical.

According to a kind of connecting pin that said structure is made, have simple in structure, easy to manufacture, easy to use, connect reliable, intensity is high, beautiful shape is fit to the advantage that unlike material connects.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is the enlarged front view of guide.Guide 1 is the cylindrical body made from timber, is shaped on columniform hole 2 at its two ends, also hole 2 can be made little conical hole 2, big the inside, aperture; Also can be shaped at the outer surface of guide 1 annular or spiral groove 3 as shown in Figure 2; Can be shaped on groove 4 as shown in Figure 3, Figure 4 in the one or both ends of guide 1 again.Fig. 5 is the enlarged front view of bearing pin, and bearing pin 5 is cylindrical bodys made from timber, is shaped on the groove 6 of annular on the surface of bearing pin 5, is shaped on chamfering 8 at the head 7 of bearing pin 5.Also bearing pin 5 can be made the big cone in head 7 little back, groove 6 also can be made into spiral.2 one-tenth interference fit of the diameter of bearing pin 5 and guide 1 cylindrical or conical hole.

Using method:

1, on two links left sides plank 9 and face that right plank 10 is connected, be drilled with the attachment hole 11 bigger slightly respectively than guide 1 external diameter, attachment hole 11 be deeply be a bit larger tham guide 1 length overall half as Fig. 6, shown in Figure 7.

2, respectively the head 7 of bearing pin 5 is inserted guide 1 aperture as shown in Figure 8 in the two-port of guide 1.

3, guide 1 one ends that will be inserted with bearing pin 5 put into right plank 10 attachment hole 11 as shown in Figure 9.

4, the attachment hole 11 of left plank 9 be inserted in guide 1 the other end as shown in figure 10.

5, at left plank 9 and the 10 both sides reinforcings of right plank guide 1 is entered in the attachment hole 11, bearing pin 5 enters in the hole 2 of guide 1, and makes and do not have visible slit between the two junction.Because entering of bearing pin 5, the hole 2 of guide 1 is strutted, and it is big that diameter becomes, and makes guide 1 be securely fixed in the attachment hole 11 of left plank 9 and right plank 10, and they are linked together as shown in figure 11 reliably.

Bearing pin 5 and guide 1 also can be made of timber or plastics or iron and steel, and the size of matching allowance between them and attachment hole 11 and the degree of depth etc. are determined according to the concrete conditions such as material of material, bearing pin 5 and the guide 1 of connected piece.To get loose in order preventing to connect,, to make connection more reliable when assembling, can a spot ofly being coated with a little tackiness agents between the fitting surface of bearing pin 5 and guide 1, guide 1 and attachment hole 11.
