As shown in the attached figure 1, the anti-falling device of the glass scrubber comprises an anti-falling rope 1 and a fixer 2, wherein the fixer 2 comprises a negative pressure suction cavity 3, in the embodiment, the negative pressure suction cavity 3 is hemispherical or bowl-shaped and is made of glass, plastic and other hard materials, the diameter of a suction opening at the bottom of the negative pressure suction cavity 3 is generally 8-15cm, and the surface of the glass is very flat, so that the suction opening can be in good sealing contact with the glass, and the negative pressure suction cavity 3 can be firmly adsorbed on the glass as long as the pressure inside the negative pressure suction cavity 3 is lower than the atmospheric pressure. In order to ensure the sealing and adsorption between the adsorption port and the glass, as shown in fig. 1, a sealing gasket 5 is applied to the edge of the adsorption port, and the sealing gasket 5 may be a rubber gasket.
As shown in fig. 1, a negative pressure suction valve 4 is provided on a wall of the negative pressure suction chamber 3, air in the negative pressure suction chamber 3 is sucked by the negative pressure suction valve 4, and when the negative pressure suction chamber 3 is separated, the pressure in the suction chamber is restored by the valve so that the negative pressure suction chamber is smoothly separated from the glass. When in suction, the suction gun can be abutted with the suction valve 4 to suck the air in the negative pressure suction cavity 3, and the structures of the suction gun and the negative pressure suction valve 4 belong to the prior art, for example, a valve body and a gun body on a suction cup are adopted, which are not described in detail herein.
When the glass cleaner is used, one end of the anti-falling rope 1 is connected with the negative pressure suction cavity 3, the other end of the anti-falling rope is connected with an outdoor cleaning piece of the glass cleaner, and the negative pressure suction cavity 3 is adsorbed on glass. The negative pressure suction cavity 3 can be adsorbed on the outdoor surface of the glass or adsorbed at the corners of the inner surface of the glass chamber, and the indoor cleaning piece is connected with a rope-free body, so that the length of the anti-falling rope can be effectively shortened, the negative pressure suction cavity 3 is taken down after cleaning is finished, and the cleaning work of the glass can be completed by cleaning the surface of the glass adsorbed by the negative pressure suction cavity 3.
When the outdoor scrubbing piece of the glass scrubber falls carelessly, the outdoor scrubbing piece can generate large impact force on the anti-falling rope, if the impact force is directly transmitted to the negative pressure suction cavity 3, the negative pressure suction cavity 3 can be separated from the glass, and the falling of the outdoor scrubbing piece and the negative pressure suction cavity 3 is formed, so that the potential safety hazard of falling objects exists.
In the present embodiment, as shown in fig. 1, a through pipe 6 penetrating the cavity is provided at the top of the negative pressure suction cavity 3, the through pipe 6 is made of a rigid material without deformation, a piston 7 capable of sliding up and down is provided inside the through pipe 6, and a seal ring (not shown in the drawing) is provided at the edge of the piston 7 to ensure the sealing property of the piston 7, so that the piston 7 and the inner wall of the through pipe 6 slide in a sealing manner.
As shown in fig. 1, the upper surface of the piston 7 is connected to the bottom end of the support spring 8, and the top end of the support spring 8 abuts against a spring abutment provided on the through pipe 6. In the present embodiment, a cap 9 is provided at the tip end of the through pipe 6, and the cap 9 is used as a spring abutment, and the tip end of the spring 8 directly abuts against the cap 9. Through setting up the dismantlement closing cap that closing cap 9 can be nimble to make things convenient for the change of spring 8 and anticreep rope 1.
As shown in fig. 1, a rope hole 10 is provided on the cover 9, and one end of the anti-slip rope 1 passes through the rope hole 10 and the inside of the spring 8 to be connected and fixed with the upper surface of the piston 7.
As shown in fig. 1, an annular limit table 11 is further arranged inside the through pipe 6 below the piston 7, and the maximum downward moving depth of the piston is controlled by the limit table 11. The stop 11 can be omitted if the resting length of the spring 8 plus the thickness of the piston 7 ensure that the piston 7 does not go beyond the bottom end of the through-tube 6.
Through setting up above-mentioned structure after, when outdoor scrubbing piece falls and drags the time of drawing to anticreep rope 1 formation, anticreep rope 1 drags piston 7 outside the motion in lining up pipe 6, and supporting spring 8 is compressed, can effectively reduce the impact force that anticreep rope 1 inhaled chamber 3 to the negative pressure through supporting spring 8's effect, prevents that the negative pressure from inhaling chamber 3 and glass and taking place the separation. In addition, when the piston 7 moves outwards, the space inside the negative pressure suction cavity 3 is enlarged, the pressure of residual air in the negative pressure suction cavity 3 is further reduced, and the difference between the internal pressure and the external pressure is further enlarged, so that the adsorption force of the negative pressure suction cavity is increased, and the adsorption stability of the negative pressure suction cavity is further ensured.
Example 2
The device still has a hidden danger at the during operation, and anticreep rope 1 is when carrying out the pulling suddenly, and its direction is indefinite, probably to having a perfect understanding pipe 6 formation slope hard, if pass through pipe 6 and negative pressure and inhale and adopt the rigid coupling between the chamber 3, the slope that the pipe 6 receives of having a perfect understanding is dragged the pulling force and is directly transmitted to the negative pressure and inhale the chamber 3 on, and the chamber 3 is inhaled to the negative pressure also causes the absorption failure easily under the effect of this oblique pulling force.
As shown in figure 1, in the embodiment, the bottom end of the through pipe 6 is flexibly connected with the negative pressure suction cavity 3. Specifically, the through pipe 6 and the negative pressure suction cavity 3 are connected and fixed by a corrugated rubber pipe 12, and the corrugated rubber pipe 12 can be bent and deformed. Adopt the flexonics back, when anticreep rope 1 drags the time of drawing to link up pipe 6, link up pipe 6 can be according to dragging the direction and slope, and the buffering through flexible ripple rubber tube 12 can reduce the direct impact of inhaling chamber 3 to the negative pressure, ensures that the negative pressure inhales firmly adsorbing in chamber 3.
