Abstract

The utility model relates to a wooden trapezoidal lock pin comprising assembly components and a bolt; the assembly components are connected by the bolt; the bolt forming a trapezoidal structure is obliquely inserted in the assembly components and is penetrated through an assembly component at an utmost outside; the assembly components are respectively provided with oblique holes and oblique through holes; contact surfaces between the assembly components can be planes or concave and convex junction surfaces; the two junction surfaces which are mutually coincide have no influence on use of the bolt; the bolt forms a cylinder; one end is a litter sharp; the bolt using the sharp end as a head is inserted into the two assembly components so that the two assembly components are tightly combined; the utility model can be used for reinforcing connection relation between the wooden assembly components so that the wooden assembly components has the advantages of no looseness, non-perishable deformation and very convenient assembly.

Description

Trapezoidal bayonet catch

Technical field

The utility model relates to a kind of wooden trapezoidal bayonet catch, is used for wooden door and window structure more.

Background technique

How to connect between at present traditional assembly parts with glue or clamp groove form, between two assembly parties that link to each other, be connected with glue besides with timber wedge, promptly on corresponding assembly parts, be provided with the hole of not running through separately, in above-mentioned hole, insert glue, again timber wedge is inserted in the above-mentioned hole, connect two assembly parties with this, the result who does like this is exactly connection between each assembly and insecure, and is loosening easily.

The model utility content

In order to overcome above-mentioned deficiency, the utility model provides a kind of wooden trapezoidal bayonet catch, just a kind of pin structure, it comprises assembly parts and pin, can connect with described pin between the described assembly parts, described pin is trapezium structure, can tiltedly be inserted among the described assembly parts, and runs through an outermost described assembly parts.

Described assembly parts can be provided with oblique hole and oblique through hole separately, surface of contact between the described assembly parts can be the plane, also can be to have certain ups and downs mating face, these two mating faces be to coincide mutually, do not influence the use of pin.Described pin is a cylindrical body, and the one end is point slightly, with this tip serving as head when being inserted among two described assembly parties, can not intersect, and two assembly parties are more closely combined.

The beneficial effects of the utility model are by using above-mentioned trapezoidal bayonet catch, can be used for reinforcing the annexation between the wooden assembly parts, make that it cannot not have looseningly, on-deformable advantage, and assemble very convenient.

Embodiment

The utility model first embodiment provides a kind of wooden trapezoidal bayonet catch, as depicted in figs. 1 and 2, comprise assembly parts 1, assembly parts 2 and pin 5, connect with described pin 5 between assembly parts 1 and the assembly parts 2, described pin 5 is trapezium structure, can tiltedly be inserted among assembly parts 1 and the assembly parts 2, and runs through an outermost assembly parts 2.

Described assembly parts can be provided with oblique hole and oblique through hole separately, is drilled with two holes 4 on assembly parts 1 from the side inwardly, obliquely, and it has certain degree of depth, but does not intersect; On assembly parts 2, be drilled with two through holes 3 that run through whole assembly parts 2 from the side inwardly, obliquely, do not intersect too, on the face that hole 4 and through hole 3 each comfortable two assembly parts are in contact with one another is one to one, and be combined into a straight straight line shape, so that pin 5 is inserted in hole 4 and the through hole 3.

Surface of contact between the described assembly parts is the plane, described pin 5 is a cylindrical body, the one end is point slightly, serving as that head is when being inserted among two described assembly parties (assembly parts 1 and assembly parts 2) with this tip, these two assembly parties are more closely combined, can be used to reinforce the annexation between the wooden assembly parts, make it more difficult loosening, not yielding.

The utility model second embodiment provides a kind of wooden trapezoidal bayonet catch equally, as shown in Figure 3, difference is, surface of contact between the described assembly parts (assembly parts 1 and assembly parts 2) is to have certain ups and downs mating face, two mating faces are to coincide mutually, do not influence the use of pin 5, so just make that assembling is very convenient.

Claims

1. a trapezoidal bayonet catch comprises assembly parts and pin, it is characterized in that, connects with described pin between the described assembly parts, and described pin is trapezium structure, tiltedly is inserted among the described assembly parts, and runs through an outermost described assembly parts.

2. trapezoidal bayonet catch as claimed in claim 1 is characterized in that described assembly parts is provided with oblique hole.

3. trapezoidal bayonet catch as claimed in claim 1 is characterized in that described assembly parts is provided with oblique through hole.
