Connecting piece and central air-conditioning air opening

Abstract

The invention belongs to a central air conditioner accessory, and particularly relates to a connecting piece and a central air-conditioning air opening. The connecting piece comprises fasteners and aconnecting plate which are arranged at corresponding positions of an air opening outer frame and an air opening inner frame, wherein the connecting plate is used for connecting the two fasteners, andthe fasteners comprise sliding blocks and limiting blocks which are connected with frame bodies; and the connecting plate is provided with a sliding groove for allowing the sliding blocks to slide, and the sliding groove is further provided with a disassembly and assembly opening which is in consistent with the limiting blocks in section shape. According to the connecting piece, the two fastenersfixed to the outer frame and the inner frame are connected through the connecting plate, the sliding blocks on the fasteners are arranged in the sliding groove in the connecting plate in a sliding mode, and therefore relative sliding of the outer frame and the inner frame can be achieved. According to the central air-conditioning air opening connected through connecting pieces, four fasteners areadditionally arranged on the basis of the existing outer frame and the existing inner frame correspondingly, and then the four sets of fasteners are connected through four connecting plates, so that the manufacturing procedure is simplified, the labor cost is greatly reduced, and materials are saved.

Description

technical field [0001] The invention belongs to a central air-conditioning accessory, in particular to a connecting piece and a central air-conditioning outlet. Background technique [0002] At present, there are two ways to open the air inlet / outlet of the central air conditioner: one is a metal bolt; the other is a plastic (elastic) buckle. [0003] Both of the above two types have some disadvantages: the former has many manufacturing processes (fixed position, punching, and rivets), and requires skilled workers to complete, with high labor costs and high material costs; the latter relies on the elasticity of plastic materials to achieve openability And close, there is a risk of falling due to external force and gravity; and the opening method is not familiar when using, and it cannot be correctly distinguished from the appearance, which increases the inconvenience of use; there are many accessories, which will increase the cost and difficulty of production and assembly. ...
