Description

Technical Field

[0001] This utility model relates to the field of air conditioning installation technology, and in particular to an auxiliary structure for outdoor installation of central air conditioning ducts. Background Technology

[0002] Central air conditioning is an air conditioning system that centrally processes and distributes air to multiple areas. It is widely used in large buildings, office buildings, shopping malls, hotels, and other places. Unlike split-type air conditioners, central air conditioning provides cooling, heating, ventilation, and air purification functions for the entire building through a single system. The installation of central air conditioning ducts is a crucial part of the installation process. Outdoor installations of central air conditioning ducts are typically used to connect indoor and outdoor units, or for ventilation needs in special situations (such as industrial plants and warehouses). Outdoor ducts need to be weather-resistant, waterproof, and have thermal insulation properties to ensure efficient system operation and extend its service life.

[0003] Currently, air conditioning duct installation lacks supporting auxiliary installation mechanisms and multi-directional angle quick adjustment structures, making it unable to adapt to different installation environments and needs. This results in low installation efficiency and requires multiple people to install and fix the ducts. Therefore, this invention proposes an auxiliary structure for outdoor installation of central air conditioning ducts to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary structure for the outdoor installation of central air conditioning ducts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A rotating shaft is rotatably connected inside the lifting seat. An angle seat is rotatably connected to the front end of the rotating shaft. Two fixing clamps are provided on the front side of the angle seat, sliding left and right on the front side of the angle seat. Two screw rods are rotatably connected inside the angle seat, fixedly connected, and threadedly connected to the two fixing clamps respectively. A support frame is rotatably connected to the lower end of the lifting seat, and an adjusting seat is rotatably connected to the lower end of the support frame, sliding back and forth on the device base.

[0007] Preferably, the upper side of the adjustment seat is provided with a plurality of slots, and the lower part of the device seat is provided with a positioning block that slides left and right, the positioning block corresponding to the slots.

[0008] Preferably, an end face gear is fixed to the rear end of the rotating shaft, and a second screw is rotatably connected to the rear side of the lifting seat. A spur gear that meshes with the end face gear is fixed to the upper end of the second screw.

[0009] Preferably, the screw is externally threaded with a slider, which slides up and down on the lifting seat, and the lifting seat has a groove corresponding to the slider.

[0010] Preferably, two positioning blocks are provided on the lower side of the front end of the rotating shaft, the positioning blocks are rotatably connected to the rotating shaft, and a torsion spring is provided at the junction of the positioning blocks.

[0011] Preferably, positioning rings are fixed on both the left and right outer sides of the angle seat transition, and a number of positioning grooves corresponding to the positioning clamps are opened on the outer side of the positioning rings, and the positioning grooves are arranged in a circular array on the outer side of the positioning rings.

[0012] Preferably, a spur gear is fixed at the junction of the positioning clamp block, and the two spur gears mesh with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model adjusts the height by sliding the lifting seat up and down, controls the direction by rotating the shaft horizontally / vertically, and adjusts the tilt angle by tilting the angle seat. It supports three-dimensional adjustment of the duct's spatial posture to meet the installation requirements of different building facades. The screw drives the end face gear-spur gear linkage to adjust the shaft angle, which is locked by the slider thread. The positioning clamp and the positioning ring spring engage to lock the tilt angle, realizing an integrated "adjustment-locking" operation to ensure stability after adjustment.

[0015] 2. This utility model features a screw that drives the simultaneous retraction and expansion of the two side clamps, applying pressure evenly to prevent duct deformation. It is adaptable to different pipe diameters. The support frame and adjustment seat form a telescopic triangular bracket, which is fixed in stages through slots and positioning blocks. The linkage positioning block enables one-button unlocking / locking of the pitch angle, and the torsion spring automatically resets, saving angle adjustment time. Attached Figure Description
