Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a connection structure that clean factory building ventilating board was used, includes ventilation pipe 1, and the air outlet department of ventilation pipe 1 is provided with ventilating board 2, and ventilation pipe 1 has seted up butt joint groove 3 towards one side of ventilating board 2 on the surface, and ventilation board 2 is fixed connection and butt joint plate 4 to 3 looks adaptations of butt joint groove towards one side of butt joint groove 3 on the surface, consequently when ventilation board 2 installs on ventilation pipe 1, and butt joint plate 4 extends into in the butt joint groove 3.

Furthermore, a built-in control cavity 5 is arranged in the inner wall of the ventilation pipe 2, a fixed slide bar 6 with the lower end penetrating into the butt joint groove 3 in a sliding mode is arranged in the built-in control cavity 5, meanwhile, the lower end of the fixed slide bar 6 is hemispherical, and a fixing groove 7 matched with the lower end of the fixed slide bar 6 is formed in the upper surface of the butt joint plate 4, so that when the fixed slide bar 6 extends into the fixing groove 7, the fixed slide bar 6 forms a limiting effect on the butt joint plate 4, and the ventilation pipe 1 is fixed on the ventilation pipe 2.

Furthermore, one end of the fixed slide bar 6, which is located in the built-in control cavity 5, is fixedly connected with a limiting pull plate 8, a movable sleeve is fixedly connected between the limiting pull plate 8 and the bottom wall of the built-in control cavity 5, a reset tension spring 9 is sleeved on the fixed slide bar 6, and one side, which is close to the ventilation pipe 1, of the butt plate 4 is in a right triangle shape, so that when the butt plate 4 extends into the butt groove 3, an inclined surface on the butt plate 4 is in contact with the lower end of the fixed slide bar 6, so that the fixed slide bar 6 moves into the built-in control cavity 5 under the extrusion of the butt plate 4, and the reset tension spring 9 stretches at the same time, when the butt plate 4 extends into the butt groove 3 completely, the fixed slide bar 6 and the fixed groove 7 are at the same vertical position, so that the fixed slide bar 6 moves into the fixed groove 7 under the tension spring 9, and thus the ventilation board 2 is fixed.

The lower end of the fixed slide rod 6 is hemispherical, so that the smoothness degree of a contact surface between the fixed slide rod 6 and the inclined surface of the butt plate 4 is increased, and the friction force generated when the fixed slide rod 6 slides along the inclined surface of the butt plate 4 is reduced, so that the problem that the fixed slide rod 6 shrinks and cannot enter the built-in control cavity 5 due to the fact that mechanical clamping is generated between the fixed slide rod 6 and the inclined surface of the butt plate 4 is avoided, and the smoothness of the connecting structure during use is effectively guaranteed.

Further, the inner wall of the built-in control cavity 5 is rotatably connected with a first gear 10, and the upper surface of the limiting pulling plate 8 is fixedly connected with a control rack 11 which is meshed with the first gear 10, so that the control rack 11 is synchronously driven to move upwards when the first gear 10 rotates anticlockwise, and the fixing slide rod 6 is pulled to move out of the fixing groove 7, so that the ventilating plate 2 can be detached from the ventilating pipe 1.

Further, a second gear 12 meshed with the first gear 10 is rotatably connected to the inner wall of the built-in control cavity 5, a third gear 13 meshed with the second gear 12 is rotatably connected to the inner wall of the built-in control cavity 5, and the diameter of the first gear 10 is twice the diameter of the third gear 13, so that when the third gear 13 rotates counterclockwise, the first gear 10 rotates counterclockwise synchronously under the transmission of the second gear 12.

Furthermore, a control pull rod 14 which penetrates through the side face of the vent pipe 1 in a sliding manner is arranged in the built-in control cavity 5, the control pull rod 14 is positioned above the third gear 13, a driving gear 15 which is meshed with the third gear 13 and connected with the third gear 13 is arranged on the surface of one side of the control pull rod 14, the surface of one side of the vent plate 2 facing the control pull rod 14 is provided with an extending sliding hole 16 which extends out of one side of the vent plate 2 back to the vent pipe 1, one end of the control pull rod 14, far away from the vent pipe 1, extends out of one side of the vent plate 2 back to the vent pipe 1 through the extending sliding hole 16, the control pull rod 14 is connected with the extending sliding hole 16 in a sliding manner, a pull plate 17 is fixedly connected to the surface of one side of the control pull rod 14, far away from the vent pipe 1, therefore, when the vent plate 2 needs to be dismounted, only the pull plate 17 needs to be pulled, so that the control pull rod 14 is synchronously moved out of the built-in control cavity 5, and therefore, the driving teeth 15 drive the third gear 13 to rotate in a counterclockwise direction, just so can make fixed slide bar 6 to shift out fixed slot 7, make this connection structure operating procedure more simple and easy through this kind of mode, reduce staff's working strength, reduced the operating difficulty and the operating time of staff when installing or demolising ventilating board 2 effectively, consequently further improved the efficiency that the staff detected the environment in ventilating pipe 1.

The diameter through first gear 10 sets up to the twice of third gear 13 diameter in this scheme, has reduced the rotatory required power of spending of third gear 13 drive first gear 10 effectively like this, has consequently reduced the operating difficulty of staff when pulling arm-tie 17 to the too big ventilating board 2 problem of dismantling the difficulty that leads to of extension spring 9 intensity that resets has been avoided.

The working principle is as follows: when the ventilation board 2 needs to be installed, the butt joint board 4 extends into the butt joint groove 3, the inclined surface on the butt joint board 4 is contacted with the lower end of the fixed slide rod 6, so that the fixed slide rod 6 moves into the built-in control cavity 5 under the extrusion lower position of the butt joint board 4, and the reset tension spring 9 stretches simultaneously, when the butt joint board 4 extends into the butt joint groove 3 completely, the fixed slide rod 6 and the fixed groove 7 are in the same vertical position, so that the fixed slide rod 6 moves into the fixed groove 7 under the pulling lower position of the reset tension spring 9, and the ventilation board 2 is fixed;

when the ventilation board 2 needs to be removed, the pulling plate 17 is pulled, so that the control pull rod 14 is synchronously moved out of the built-in control cavity 5, the driving teeth 15 drive the third gear 13 to rotate anticlockwise, the control rack 11 is synchronously driven to move upwards, the fixing slide rod 6 is pulled to move out of the fixing groove 7, and the ventilation board 2 can be removed from the ventilation pipe 1.
