Connecting structure

Technical Field

The utility model belongs to the field of furniture, a connection structure is related to.

Background

The current furniture market is wide in variety, the requirements of people on furniture are higher and higher, and the requirements on the attractiveness of the furniture are higher and higher when the furniture is selected and purchased in addition to the stability of the furniture. For example, in furniture products such as tables and chairs, because the furniture products are assembled by a plurality of parts, the traditional connecting structure is generally installed by hardware fittings such as bolt and screw or a joggle, wherein the joggle is complex in installation structure, and the stability of the installation mode of the bolt and the screw is relatively poor.

Such as chinese patent application No.: CN200720057267 discloses a seat back connector of office chair, this connector includes side connecting plate and the end connecting plate that is the L type, and two adjacent sides on the side connecting plate respectively with two side fixed connection on the end connecting plate, still seted up a plurality of screw mounting holes on the end connecting plate. When using the installation, only need paste the both sides of end connecting plate respectively and lean on adjacent two treat the equipment parts, the rethread bolt installation can realize connecting, and the installation is very simple, and the side connecting plate can increase the stability of structure simultaneously, prevents that the end connecting plate of L type from taking place deformation.

However, the connector is usually integrally formed, and due to the connection between the side connecting plate and the bottom connecting plate, the connector cannot be adjusted, the requirement on the matching degree of parts to be assembled in an application place and the connector is high, but on the basis of machining precision, the verticality between the parts to be assembled has deviation, the connector cannot be installed with the parts, and the connector and the assembled parts have poor structural stability and poor applicability. In this regard, it is readily conceivable by the person skilled in the art to provide the side webs with a gap so that the base webs can be adjusted relative to one another, but this can easily affect the structural strength.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a connection structure, the utility model aims to solve the technical problem that: the existing connecting structure cannot simultaneously improve the applicability and the structural strength.

The power of two positions of installation department and supporting part is concentrated the crooked section portion department, and the crooked section portion that is the arcuation can strengthen the stability of this structure to crooked section and installation department, supporting part rounding off are connected and can be reduced between supporting part and the installation department because stress concentration takes place cracked possibility, have guaranteed whole connection structure's structural strength.

In the above connection structure, the lower surface of the curved section is an upwardly concave arc surface. The supporting part is when resisting connecting portion self deformation, and the crooked section can be effectual with this power guide transition to the installation department to this connection structure's structural strength is guaranteed.

In the above connection structure, the height of the support portion gradually increases from one end of the support portion away from the mounting portion to the mounting portion. Set up like this and to guarantee that the connection between supporting part and bending segment and the installation department is stable, and its three atress is more stable to this guarantees structural strength.

In the above connection structure, the mounting portion and the lower surface of the support portion are smoothly transited. Can guarantee again when structural strength like this can guarantee that crooked section and supporting part lower surface can not the fish tail user's hand, guarantee the security.

In the above connection structure, the height of the mounting portion is greater than that of the supporting portion, and the height of the mounting portion is greater than that of the bending portion. The aforesaid shows the installation department be used for with treat that equipment part erection joint, consequently the installation department is final stress point, the stress intensity of installation department is greater than bending section and supporting part, highly the design is in order to guarantee the stable transmission of power between the three between installation department and bending section, the supporting part, the design that the installation department is greater than the kink is then in order to reserve the space that supplies the user to install, avoids causing the hindrance to the installation as far as possible, realizes convenient installation.

In the above connection structure, the mounting portion is located at an edge of the connection portion, and a shape of a side of the connection portion connected to the mounting portion is identical to an extending shape of the mounting portion. Through the design of above-mentioned structure, guarantee the holistic aesthetic property of connection structure.
