DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 , a building curtain wall air tightness detection device capable of adjusting position in multiple directions, comprises a base 1, a first negative pressure cover 4 and a second negative pressure cover 5, the second negative pressure cover 5 is provided with a one-way valve, an air bag and an adsorption member, a hydraulic cylinder 2 is fixedly arranged on the base 1, a driving end of the hydraulic cylinder 2 is fixedly connected to a support block 11, a bracket 8 is slidably arranged above the support block 11, a rotating frame 7 is rotatably connected to the bracket 8, a negative pressure pump is arranged on the rotating frame 7, the negative pressure pump is communicated with the first negative pressure cover 4 through a connecting pipe, the first negative pressure cover 4 and the rotating frame 7 are fixedly connected, an annular plate 16 is fixedly connected to the rotating frame 7, a plurality of through holes are opened on the annular plate 16, a limiting assembly is arranged on the bracket 8, the limiting assembly comprises a limiting rod 19 connected to the bracket 8 through a first spring 20, the cross section of the limiting rod 19 is U-shaped, a rotating plate 14 is connected to the bracket 8 through a torsion spring 15, a protrusion 10 is fixedly connected to the rotating plate 14, and the protrusion 10 is clamped with the limiting rod 19.

[0024] A fixing rod 13 with an L-shaped cross section is slidably connected to the bracket 8. The surface of the fixing rod 13 fits the surface of the rotating plate 14. The upper surface of the support block 11 is provided with a plurality of circular grooves 18 for connecting the fixing rod 13. When the lower end of the fixing rod 13 is engaged with the circular groove 18, relative movement between the bracket 8 and the support block 11 can be prevented. During the upward movement of the fixing rod 13, under the elastic force of the torsion spring 15, the rotating plate 14 will rotate upward, and the protrusion 10 will disengage from the slot on the limit rod 19 after moving.

[0025] A second spring 17 is sleeved on the fixing rod 13, one end of the second spring 17 is fixedly connected to the fixing rod 13, and the other end of the second spring 17 is fixedly connected to the bracket 8. A rubber sleeve 12 with a circular cross-section is fixedly connected to the lower surface of the bracket 8. The surface of the rubber sleeve 12 with a circular cross-section fits the outer surface of the fixing rod 13. The friction between the fixing rod 13 and the rubber sleeve 12 is relatively large, which can effectively prevent the fixing rod 13 from moving at will.

[0026] The first negative pressure cover 4 and the second negative pressure cover 5 are fixedly connected to one side surface with a sealing ring 6, and the sealing ring 6 is set to a rubber material. The rubber sealing ring 6 can improve the sealing performance of the first negative pressure cover 4 and the second negative pressure cover 5 when they are in contact with the curtain wall surface. The support block 11 is provided with a slide groove with a convex cross-section. A convex block 9 is slidably connected in the slide groove. The convex block 9 is fixedly connected to the bottom surface of the bracket 8. The coordinated use of the convex block 9 and the slide groove can limit the moving trajectory of the bracket 8 so that the bracket 8 can move stably along the support block 11. A plurality of fixed plates are fixedly connected to the bottom surface of the base 1, and each fixed plate is rotatably connected with a pulley 3 to push the base 1. Each pulley 3 rolls on the ground to facilitate the rapid movement of the device.

[0027] In the present invention, in the initial state, the lower end of the fixing rod 13 is inserted into the corresponding circular groove 18, the surface of the fixing rod 13 and the upper surface of the rotating plate 14 are fitted, and the fixing rod 13 is pulled upward. During the relative sliding of the fixing rod 13 and the bracket 8, the second spring 17 is deformed. After the fixing rod 13 moves up, one end of the torsion spring 15 is fixedly connected to the rotating plate 14, and the other end is fixedly connected to the bracket 8. Under the elastic force of the torsion spring 15, the rotating plate 14 will rotate upward, and the protrusion 10 will be disengaged from the slot on the limit rod 19 after moving. At this time, the lower end of the fixing rod 13 is still located in the circular groove 18, and the fixing rod 13 is moved upward. When the limit rod 19 is pulled outward and the limit rod 19 and the bracket 8 slide relative to each other, since one end of the first spring 20 is fixedly connected to the limit rod 19 and the other end is fixedly connected to the bracket 8, the first spring 20 is deformed until one end of the limit rod 19 is separated from the through hole and the limit rod 19 is located on one side of the annular plate 16 as a whole. After that, the rotating frame 7 and the bracket 8 can be rotated relative to each other, thereby changing the inclination angle of the first negative pressure hood 4. When the building curtain wall is tilted or has an inclined surface during detection, the first negative pressure hood 4 can conveniently adjust the inclination angle according to the inclination degree of the curtain wall. The operation is relatively convenient, which is conducive to the use of the detection device.

[0028] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
