Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 2 and 3, for the utility model discloses a basement ventilation structure, including hang in ventilation pipe 1 of basement top, set up suction opening 2 and air outlet 3 on ventilation pipe 1, when in-service use, suction opening 2 takes the wind in the basement out, and air outlet 3 insufflates the air in the basement with external air, guarantees the effect of the air cycle of basement.

In order to prevent dust from adhering to the side wall of the suction opening 2, a dust cover 4 is covered on the suction opening 2, the dust cover 4 comprises an installation frame 5 and a dust screen 6 installed on the installation frame 5, and the installation frame 5 is of a rectangular opening-shaped structure made of plastic materials. In order to install the dust screen 6 on the installing frame 5, a plurality of installing posts 7 for the dust screen 6 to penetrate through and install are integrally arranged on the installing frame 5, and when the dust screen 6 is installed on the frame, the dust screen 6 is hung on the installing posts 7 arranged on the installing frame 5. Besides, the ventilation pipe 1 is provided with a fixing part 8 for fixing the mounting frame 5, and the fixing part is used for fixing and mounting the mounting frame 5.

Referring to fig. 4 and 5, the fixing member 8 includes an elastic block 9 and a connection hole 10 opened on the elastic block 9, the elastic block 9 is a metal sheet structure disposed on the ventilation pipe 1, and the elastic block 9 is provided with four blocks and extends toward the direction of the mounting frame 5. The connecting hole 10 is opened on the elastic sheet and is arranged through the elastic block 9. The mounting frame 5 is integrally provided with a connecting block 11 which is fixedly clamped with the connecting hole 10. When installing frame 5 to ventilation pipe 1 on, only need connecting block 11 joint to the connecting hole 10 on the elastic block 9 in, can be with installing frame 5 joint to elastic block 9 on to install installing frame 5 to ventilation pipe 1 on.

In order to conveniently clamp the connecting block 11 on the mounting frame 5 into the connecting hole 10 on the elastic block 9, a guide surface 12 for guiding the elastic block 9 to deform is arranged on the connecting block 11, and the guide surface 12 is gradually inclined to one side close to the mounting frame 5 along the direction that the connecting block 11 is inserted into the connecting hole 10 in a clamping manner. In the in-process with connecting hole 10 mutual joint on connecting block 11 and the elastic block 9 on the installing frame 5, elastic block 9 can earlier contact with guide face 12 on the connecting block 11, because guide face 12 slope sets up, elastic block 9 can order about elastic block 9 to the direction of keeping away from installing frame 5 and take place crooked deformation with the in-process of guide face 12 contact, position until connecting hole 10 moves connecting block 11 department, elastic block 9 replies deformation, connecting hole 10 on the elastic block 9 can take place the joint with connecting block 11, make things convenient for the installation of installing frame 5.

When the mounting frame 5 needs to be replaced, the connecting holes 10 on the elastic block 9 need to be separated from the connecting blocks 11. One side of the elastic block 9 far away from the mounting frame 5 is integrally provided with a pulling block 17. In this embodiment, the pull block 17 is arranged in a T shape, and when the mounting frame 5 needs to be taken down, only the pull block 17 needs to be pulled to drive the elastic block 9 to be bent and deformed until the connecting hole 10 is separated from the connecting block 11, so that the mounting frame 5 can be taken down from the elastic block 9.

Referring to fig. 6 and 7, in order to fix the elastic block 9 to the ventilation pipe 1, an insertion column 13 is arranged on one side of the elastic block 9 close to the ventilation pipe 1, and the insertion column 13 is of a cylindrical structure and extends towards the ventilation pipe 1. One side of the insertion column 13 far away from the elastic block 9 is integrally provided with a clamping block 14, and the clamping block 14 is matched with the insertion column 13 to form a T-shaped structure. The ventilation pipe 1 is provided with an inserting hole 15 for the inserting and sliding of the inserting column 13 and the clamping block 14, the ventilation pipe 1 is further provided with a clamping groove 16 for the rotary clamping of the clamping block 14, and the clamping groove 16 is communicated with the inserting hole 15. In actual operation, the inserting column 13 and the clamping block 14 need to be inserted into the inserting hole 15; it should be noted that, in the process of inserting the inserting-connecting column 13 and the clamping block 14 into the inserting-connecting hole 15, the length direction of the elastic block 9 is parallel to the direction of the air suction opening 2. After inserting into plug hole 15 when peg 13 and joint piece 14, rotatory elastic block 9 makes joint piece 14 joint to joint groove 16 in to make elastic block 9 can not drop from ventilation pipe 1 because the joint of joint piece 14 with joint groove 16. The elastic block 9 can be fixed to the ventilation tube 1. After the elastic block 9 is rotated, the elastic block 9 is perpendicular to the suction opening 2 and protrudes toward the mounting frame 5.

Referring to fig. 8 and 9, in order to prevent dust from entering the sidewall of the suction opening 2 from the gap between the mounting frame 5 and the ventilation pipe 1, a sealing ring 18 abutting against the mounting frame 5 is disposed on the ventilation pipe 1, and the sealing ring 18 is made of rubber and has a mouth-shaped structure adapted to the mounting frame 5. In order to facilitate the installation of the sealing ring 18 on the ventilation pipe 1, a plurality of connecting columns 19 are integrally arranged on one side of the sealing ring 18 close to the ventilation pipe 1, and the connecting columns 19 extend out towards the ventilation pipe 1. The ventilation pipe 1 is provided with a connecting groove 20 for inserting and fixing the connecting column 19 and corresponding to the connecting column 19 one by one. When the sealing ring 18 is mounted on the vent pipe 1, the connecting column 19 on the sealing ring 18 is aligned with the connecting groove 20 and inserted into the connecting groove 20. In order to make the insertion of the connection post 19 into the connection groove 20 more stable, a protrusion 21 abutting against the sidewall of the connection groove 20 is integrally formed on the connection post 19. After the connecting column 19 is inserted into the connecting groove 20, the rib 21 on the side wall of the connecting column 19 is extruded and deformed, and the deformed rib 21 fills the gap between the connecting column 19 and the connecting groove 20, so that the damping of the connecting column 19 inserted into the connecting groove 20 is larger, and the connecting column 19 inserted into the connecting groove 20 is more stable.

Besides, the side wall of the sealing ring 18 is provided with a plurality of deformation grooves 22, and the deformation grooves 22 enable the outer side wall of the sealing ring 18 to form a wavy shape. When the installing frame 5 is installed on the ventilation pipe 1, the installing frame 5 can be extruded with the sealing ring 18, and the deformation groove 22 is arranged, so that the sealing ring 18 can be deformed more easily after being extruded, the installing frame 5 can be fixed on the elastic block 9 more conveniently, and the working efficiency is improved.

The implementation principle of the embodiment is as follows: when installing, install elastic block 9 to ventilation pipe 1 earlier, insert through spliced pole 19 with sealing washer 18 and spread groove 20 and close fixedly again, pass through the fixed of mounting 8 with installing frame 5 at last to install installing frame 5 to elastic block 9 on, install dust screen 6 to installing frame 5 through erection column 7 on can at last.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
