Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Please refer to Fig. 1 to Fig. 3, the present invention stays door gear and is fixed in a body 21 rear side shop fronts, has tubing string 2, sucker 1 and Joining clasp. Joining clasp comprises the first Joining clasp 11 and the second Joining clasp 12, and both are fixedly connected in a body 21 rear side shop fronts, and tubing string 2 activities are plugged in Joining clasp, and sucker 1 is arranged on the lower end of tubing string 2.
As Fig. 4, the tubing string 2 of the present embodiment is hollow cylinder, comprises pipe 210 and end socket 3, and end socket 3 is connected to pipe 210 upper ends, by the upper end closed of tubing string 2. The hollow lumen of tubing string 2 comprises the stem stem chamber and the venting cavity 9 that are interconnected and set gradually from top to bottom.
For realize sucker 1 can free adsorbing in door body 21 scopes of activities below on ground 22, on tubing string 2, be provided with sucker intake and exhaust mechanism, this sucker intake and exhaust mechanism comprises driving lever 7, stem stem 5, spring 4 and cushion 8, stem stem 5 and spring 4 are placed in the stem stem chamber of tubing string 2, spring 4 is compressed to be arranged between stem stem top of chamber and stem stem 5, stem stem 5 lower surfaces is closely against to the upper port of venting cavity 9. Driving lever 7 one end connect one end of stem stem 5 and stretch out outside tubing string 2 through the sidewall of tubing string 2. The Shang Qie center, lower surface that cushion 8 is fixed on stem stem 5 is provided with passage to be made it to connect with the venting cavity 9 at tubing string 2 centers. Because spring 4 is compression settings, there is the elastic force stretching outward, stem stem 5, under this elastic force effect, is tight against the cushion 8 on stem stem 5 lower surfaces on the blow vent of venting cavity 9 upper ends.
When door body 21 moves to need to park in a certain position time, sucker 1 is landed, and light press seal head 3, tubing string 2 moves down and pushes sucker 1, air in sucker 1 is extruded in venting cavity 9 and backs down the cushion 8 that is pressed in venting cavity 9 upper port, after Bas Discharged in sucker 1, make the interior formation negative pressure of sucker 1, because spring 4 is all the time in outside stretched condition, after Bas Discharged in sucker 1, cushion 8 is under the effect of spring 4, seal in time venting cavity 9 upper port, air in sucker 1 external world can not enter in sucker 1 again by venting cavity 9 upper port, now sucker 1 is securely adsorbed on ground 22, thereby a body 21 is maintained static, use the present invention's time in door gear, ground 22 is required smooth bright and clean, and to sucker 1 non-corrosiveness.
Change and dismantle in order to facilitate sucker 1, connect a sleeve 10 in sucker 1 upper end, on the inner peripheral wall of the upper end of this sleeve 10, internal thread is set, center arranges passage 101, on the lower end outer circle wall of pipe 210, be provided with the external screw thread suitable with above-mentioned internal thread, sucker 1 is detachably connected on pipe 210 lower ends by externally threaded the spinning of internal thread on sleeve 10 and tubing string 2 lower ends simultaneously. Sleeve 10 upper vent hole 101 Yu Guan 210 center venting cavities 9 connect, and in two junctions, hole, center are set and are provided with the sealing gasket 13 of passage, make venting cavity 9 lower ends be sealedly attached to passage 101.
In the time that door transfers rotary state to by docked state, need to remove the absorption affinity of sucker 1, for this reason, be provided with discharge chamber 6 at the sidewall of tubing string 2 corresponding to the position of described driving lever 7, the hole that this discharge chamber 6 is radial direction, connects with the stem stem chamber on tubing string 2. Simultaneously driving lever 7 extend in discharge chamber 6 its one end by this discharge chamber 6 and spiral is connected on stem stem 5. The aperture of discharge chamber 6 is greater than the diameter of driving lever 7, thereby driving lever 7 can be moved up and down in discharge chamber 6. Will remove a body 21 positions when fixing, driving lever 7 is upwards gently dialled, the elastic force that driving lever 7 drives stem stem 5 to overcome spring 4 moves upward, stem stem 5 drives cushion 8 to move upward together, now outside air enters into sucker 1 by venting cavity 9 upper end blow vents, negative pressure in sucker 1 is removed, the present invention's disengaging in door gear ground, and 21 activities of door body are freely.
Please refer to Fig. 5 to Fig. 7, Joining clasp comprises the first Joining clasp 11 and the second Joining clasp 12 that arrange along tubing string 2 axial directions, the first Joining clasp 11 comprises the first connecting plate 110 and the first connecting ring 111, the second Joining clasp 12 comprises that the second connecting plate 120 and the second connecting ring 121, the first connecting rings 111 and the second connecting ring 121 are fixedly connected on the first connecting plate 110 and the second connecting plate 120 by the 3rd connecting plate 112 respectively. Wherein on the first connecting plate 110 and the second connecting plate 120, be equipped with screwed hole 1100. Joining clasp, by the screw that spins at screwed hole 1100, is fixed in the shop front of a body 21; Or according to door body 21 materials, the length of service time and environment for use, can take the modes such as the bonding and sucker of seccotine is fixing that Joining clasp is fixed in the shop front of a body 21.
The present invention stays door gear in the time not using, between sucker 1 and ground 22, contact, thereby the movement of impact door body 21, and door body 21 moves the friction infringement that sucker 1 is caused, by apparatus of the present invention in the time not using, be articulated on snap ring, the first connecting ring 111 on the first Joining clasp 11 is arranged to the open loop with bayonet socket 1111, and on the anchor ring of the first connecting ring 111 upper ends, be provided with the groove 1110 being disposed radially, bayonet socket 1111 is all suitable with driving lever 7 with groove 1110, do not using the present invention's time in door gear, driving lever 7 is placed in the groove 1110 of the first connecting ring 111 upper surfaces, now sucker 1 departs from ground 22, and when moving door body 21, sucker 1 also can not contact with ground 22. in the time that door body 21 need to be parked, stir driving lever 7 to bayonet socket 1111, press end socket 3, sucker 1 is adsorbed on ground 22, realizes door body 21 and parks.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make under the premise without departing from the principles of the invention some improvement, and these improve and also should be considered as protection scope of the present invention.
