Problems solved by technology

[0003] Both the universal connector and the pipe connector have their own shortcomings and cannot be applied to the vacuum cleaner. The Chinese patent application number 03130050.2 discloses a connection device between the handle and the hose; the application number is 98109388.4 The Chinese patent discloses a rotatable connector between the hose and the handle part. Both patents provide a connector between the hose and the handle, and do not disclose it between the dust collection hood and the dust removal pipe. set connector

Embodiment 1

[0043] Such as figure 1 , 2 As shown, a variable angle connector includes a large-diameter hemispherical connector 1, a small-diameter hemispherical connector 2, a bearing 5, a bearing end cover 6, a radial fastening ring 7, a card slot 8, and a stepped shaft 19 ;

[0044] refer to Figure 4 , 5It can be seen that there is a circular cut surface a1 20 on the surface parallel to the section of the large-diameter hemispherical connector 1, and two circular cut surfaces a2 21 are cut out on both sides of the circular cut surface a1 20, and on the circular cut surface a2 21 Two circular planes a3 are fixed, and a slot 8 connecting the circle center and the boundary is provided on the circular plane a3;

[0045] On the surface parallel to the section of the small-diameter hemispherical connector 2, there is a circular cut surface b1 22, and two circular cut surfaces b2 23 are cut out on both sides of the circular cut surface b1 22, and two circular cut surfaces b2 22 are fixed ...

Embodiment 2

[0054] Such as image 3 As shown, a variable-angle connector connected to the vacuum cleaner, the variable-angle connector is connected between the dust collection cover 11 and the dust removal pipeline 10, and also includes a large-diameter hemispherical connector 1, a small-diameter hemispherical Connector 2, first pipe 3, second pipe 4, bearing 5, bearing end cover 6, radial fastening ring 7, card slot 8, first hoop 9, second hoop 18, stepped shaft 19;

[0055] Wherein, there is a circular section a1 20 on the surface parallel to the section of the large-diameter hemispherical connector 1, the circular section a1 20 is fixedly connected with the second pipeline 4, and the diameter of the circular section a1 20 is the same as the diameter of the second pipeline 4 Same; cut out two circular planes a2 21 on both sides of the circular plane a1 20, fix two circular planes a3 on the circular plane a2 21, the diameter of the circular plane a3 is the same as that of the circular pl...

Embodiment 3

[0061] Install the variable-angle connector in smoking areas in public places such as shopping malls, hospitals, restaurants, etc., sense the position of the smoke through the smoke sensing device, drive the variable-angle connector to change the angle through the transmission mechanism, and track the position of the smoke to achieve more Efficient dust collection effect, reducing the amount of smoke and dust in public places, especially indoors, improving air quality and reducing pollution.

Abstract

The invention relates to a variable-angle connector. The variable-angle connector is mainly applied to connection between a dust hood and a dust removal pipe in an industrial dust removal system. The connector comprises a large-diameter hemispheric connector (1), a small-diameter hemispheric connector (2), a bearing (5), a bearing end cover (6), a radial fastening ring (7), a clamping groove (8) and a stepped shaft (19), wherein the small-diameter hemispheric connector (2) is connected onto the large-diameter hemispheric connector (1) through the stepped shaft (19), then the radial fastening ring (7) is sleeved, the bearing (5) and the bearing end cover (6) are assembled and screws are tightened. The connector can realize angle change from 0 degree to 45 degrees, the space limitation is broken through, the dust hood is not like the traditional dust hood which is fixed at a position in a space but is enabled to flexibly track smoke dust according to the produced amount and scattering direction of the dust smoke, the dust suction range is expanded, the maximum-efficiency absorption is achieved and the environmental quality is improved.

Description

technical field [0001] The invention relates to a variable-angle connector, which is mainly used in the connection between a dust collection hood and a dust removal pipeline in an industrial dust removal system. Background technique [0002] Existing connectors are mainly divided into two categories, one is a universal connector and the other is a pipe connector. Among them, the main features of the pipe connector are: the front and rear parts are provided with flange pressure plates, and the inner cavity is provided with seals and clamping parts. Its main purpose is to connect two pipes horizontally and at fixed angles. The two sections of pipeline are fastened through the connector, and the rear end of the flange compression plate and the connecting body is fixed by axial bolts, so that it is very leak-proof, and the operation is convenient and fast, but there is one disadvantage that it is impossible to make an angle after fixing Transformation, such as the Chinese paten...
