Firm section material connection structure

Abstract

The invention discloses a firm section material connection structure. The section material connection structure comprises a first section material unit and a second section material unit, wherein the first section material unit comprises a first embedding pit of which the left wall is a left side plate and the right wall if a middle column, and a second embedding pit of which the left wall of the middle column and the right wall is a right side plate or a right side plate combination; the second section material unit comprises a middle column containing pit; the left wall of the middle column containing pit is a first connecting hook of which the tail end is fixed in the first embedding pit, and the right wall of the middle column containing pit is a second connecting hook of which the tail end is fixed in the second embedding pit; the tail end of the middle column is positioned in the middle column containing pit; the first embedding pit, the middle pit containing pit, and the second embedding pit are arranged in order from left to right. According to the firm section material connection structure, the situation that a traditional dual-edge clip hook structure must forms a cavity is omitted, so that the volume of the connection structure is greatly reduced. The connection structure is ingenious in structure, is safe and stable, is quick and convenient to assemble, and can be widely used in connection structures of section material units.

Description

technical field [0001] The invention relates to a connection structure of profiles in the field of profiles. Background technique [0002] In order to achieve the required profile shape, many profiles are formed by connecting profile units, such as double-color glue injection profiles or spliced ​​profiles. However, for combined profiles, it is often difficult to resist torsion and easy to loosen between its profile units, so most of the existing designs use the connection structure of double-sided hooks. refer to figure 1 , the connection structure of the bilateral hooks, including the left profile unit 1a and the right profile unit 2a, the right profile unit 2a stretches out two right connecting hooks 21a to the left up and down, and the left profile unit 1a stretches out two pairs of connecting groups to the right, respectively The two right connecting hooks 21a are connected, specifically, each pair of connecting groups includes an abutment plate 11a on the outside tha...

Problems solved by technology

But this connection structure has an obvious defect: in order to resist the left and right torque, it has to make two pairs of connection groups (if one is missing, the reverse torque can easily loosen the hook joint, and the abutment plate is not at all can not be blocked), and the upper and lower connecting groups cooperate with the upper and lower right connecting hooks, naturally forming a cavity 3a when combined, the cavity 3a is bulky and takes up space, making it difficult for engineers to design a portable combination Profiles, for example, only one type of "I" type combined profiles needs to be provided in actual work, but according to the design of the double-sided hook connection structure, the "II" type will eventually be produced

And to form a double-sided hook connection structure, it is necessary to apply force to the panels of the left profile unit 1a and the right profile unit 2a, which will easily deform the panels
