Defect:
(1) employing carries out security protection with upper type, although can play the effect that warning is reminded, but due to common band
Formula is stretched does not has fixation between enclosure seat and large cover, fence is placed built on the sand；
(2) easily it is subjected to displacement under the least External Force Acting, even topples over, be not reaching to the purpose of essential safety；
(3) it is susceptible to variation due to position during using, and then result in the change of position during use, bring
Hidden danger.
Utility model content
This utility model provides the belt of a kind of band sucked type base to stretch fence, this fence and common rustless steel belt
Flexible fence differ primarily in that base portion, the base of this fence is designed as a kind of sucked type base, base be connected convex
Platform inner space, one exhaust passage of boss design, a ball valve is installed, base sucking disc can be controlled by the switch of ball valve
Interior air pressure.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that a kind of band sucked type base
Belt stretch fence, it includes that sucker base, the top of described sucker base are provided with top pressure closure, described top pressure closure with
Sucker base is connected, and the sidewall at top pressure closure is provided with air inlet and outlet device, and the top of described top pressure closure is provided with connection
Boss, the center of described connection boss is threaded hole, has been threaded connection fence vertical rod inside described screwed hole, described
The top of fence vertical rod is provided with and is linked with connecting rod.
Described sucker base includes sealing shirt rim, and sealing on shirt rim is telescopic bellows, described telescopic bellows energy
Enough by flexible discharge inner air tube, form vacuum cavity.
Described air inlet and outlet device includes that exhaustor, one end of described exhaustor are connected on top pressure closure, and with sucker at the bottom of
Seat is connected, and described exhaustor is provided with ball valve switch.
Described sealing shirt rim and telescopic bellows all use rubber or polyurethane material to make.
Described fence vertical rod uses stainless steel tube.
Described exhaustor is removably connected by screw thread and is connected with top pressure closure.
This utility model has the advantages that:
1, by the stretching motion of telescopic bellows, it is possible to form vacuum therein, and then ensure to achieve sealing
Connection between shirt rim and ground, closes telescopic bellows by ball valve switch, and then maintains its internal vacuum environment,
Thus ensure that the connection between whole fence vertical rod and ground.
2, open exhaustor by ball valve switch, make telescopic bellows be connected with air, change its vacuum environment, energy
Enough unclamp the connection between telescopic bellows and ground.
3, the dismounting of fence vertical rod is facilitated by fence vertical rod with removably connecting of being connected between boss.
4, the sucked type base of fence is designed as rubber or polyurethane material, and fence overall weight is light, it is simple to carrying and
Use.
5, sucked type base, easy to use, fence steadiness is good.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is structural representation during this utility model uses.
In figure: seal shirt rim 1, telescopic bellows 2, exhaustor 3, ball valve switch 4, top pressure closure 5, connection boss 6, enclose
Hurdle vertical rod 7, it is linked with connecting rod 8, shroud 9.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
The fence as it is shown in figure 1, the belt of a kind of band sucked type base is stretched, it includes sucker base, described sucker base
Top be provided with top pressure closure 5, described top pressure closure 5 is connected with sucker base, the sidewall at top pressure closure 5 be provided with into
Exhaust apparatus, the top of described top pressure closure 5 is provided with connection boss 6, and the center of described connection boss 6 is threaded hole,
Being threaded connection fence vertical rod 7 inside described screwed hole, the top of described fence vertical rod 7 is provided with and is linked with connecting rod 8.
Further, described sucker base includes sealing shirt rim 1, and sealing on shirt rim 1 is telescopic bellows 2, described can
Expansion corrugated pipe 2 can discharge inner air tube by flexible, forms vacuum cavity.
Further, described air inlet and outlet device includes that exhaustor 3, one end of described exhaustor 3 are connected to top pressure closure 5
On, and be connected with sucker base, described exhaustor 3 is provided with ball valve switch 4.One ball valve is installed, ball valve can be passed through
Switch control the air pressure in base sucking disc.
Further, described sealing shirt rim 1 and telescopic bellows 2 all use rubber or polyurethane material to make.Inhale
Disc type base is designed as rubber or polyurethane material, and fence overall weight is light, it is simple to carries and uses.
Further, described fence vertical rod 7 uses stainless steel tube.And then reduce the weight of whole device, facilitate it to remove
Fortune.
Further, described exhaustor 3 is removably connected by screw thread and is connected with top pressure closure 5.
Further, sucked type base can be designed to the profile of other mechanism, such as sucker base, size etc.
Adjust as required.Sucker base can also be designed as the structure more simplified, and uses screw thread advance and retreat formula to control the pressure in sucker chamber.
Specific works process of the present utility model and operation principle be:
Utilize the air pressure difference inside and outside sucker.Before this fence uses, valve is in opening, when using fence, and will
Fence is placed on the ground, firmly presses downwards, and in base sucking disc, air is discharged by steam vent, closes ball valve, now, in sucker
Close to vacuum, sucker firmly holds ground, reaches the purpose that fence is firm.When needs are mobile or remove fence, manual unlocking
Valve, air enters base sucking disc by valve, destroys vacuum, and fence just can easily move.
