Abstract

The utility model discloses a lockable negative pressure sucker, It characterizes in that: it comprises a pull rod, a housing, a rubber sheet, a spring and a handle. The upper convex of the housing is provided with a blind hole. The pull rod passes through a airtight space formed by the housing and the rubber sheet, one end being permanently connected with a liftout plate embedded at the center of the rubber sheet and the other end is connected with the handle and the positioning pins. And the spring cover is positioned on the pull rod. The utility model can not only prolong the absorption time and reinforce the absorption ability, but also increase the application range of the negative pressure sucker, which can be extensively used in the absorption and locking fields of car shade umbrellas on the front and rear windscreens of the car.

Description

A kind of lockable negative pressure sucker

Technical field

The utility model has related to a kind of negative pressure sucker that can be with lock, and especially it can lock very easily, open, and can strengthen the adsorption time of negative pressure sucker greatly.

Background technique

Industrial use negative pressure sucker is more universal, and is all very necessary moving as coming by negative pressure sucker as article large-scale, that smoothly give a hand nowhere again such as carrying glass, steel, marbles, is used for industry to use and generally need not lock at factory, enterprise work because be.Along with negative pressure sucker is diverted from one use to another gradually in civilian, as be used for extension commodity, the mobile advertisement of pitch flow and be used to can be the parasols of automobile sun-shading now summer, but these article that are positioned over the public place are easy to again be stolen by the people, so negative pressure sucker there has been the demand that locks.

The model utility content

In order to overcome the absorption that existing negative pressure sucker can be firm, but the defective that can not lock, technical problem to be solved in the utility model is to propose a kind of negative pressure sucker that can be with lock, and it can lock very easily, open, and can strengthen the adsorption time of negative pressure sucker greatly.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of lockable negative pressure sucker, form by pull bar, housing, rubber plate, spring and handle, and convex with a blind hole on the housing; Pull bar passes the confined space of housing and rubber plate formation, and an end is fixedlyed connected with the riser that is embedded in the rubber plate central position, and the other end links together by locating stud and handle; Spring housing is located on the pull bar.

As optimal technical scheme of the present utility model, preferably be provided with a cavity on the above-mentioned handle, the lock core that accommodates spring in the cavity and lock by set screw, lock core and above-mentioned blind hole lock mutually.

With respect to prior art, the utility model increases by one pair of core, spring at the heart of traditional negative pressure sucker negative pressure spanner, and set up a blind hole hasp in the outer ring of sucker, when the sucker handle is depressed, lock core in the handle is pressed to the window of inhaling bowl place blind hole under the suppressing of spring, make the sucker locking handle.The utility model can make negative pressure sucker prolong the using scope of adsorption time, enhancing adsorptive power, increase negative pressure sucker.

Description of drawings

Fig. 1 is that the utility model negative pressure sucker lock is opened figure.

Fig. 2 be the utility model negative pressure sucker finish locking figure.

Fig. 3 is the utility model negative pressure sucker handle parts drawing.

Fig. 4 is that the utility model negative pressure sucker is inhaled the bowl parts drawing.

Wherein: 1 is handle; 2 is lock core; 3 is set screw; 4 is spring; 5 is locating stud; 6 is lift shaft; 7 is blind hole; 8 is the turriform spring; 9 is riser; 10 is rubber plate; 11 is key; 12 is keyhole.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in figs. 1 and 3, the lock cores 2 in the 3 locking negative pressure sucker handles of the set screw in the handle of a kind of lockable negative pressure sucker of the utility model one preferred embodiment proposition are in case the lock core ejection; With locating stud in the negative pressure sucker handle 5 is axle center when pressing downwards, and lock core is pressed to a window of inhaling bowl place blind hole 7 under the elastic force of spring 4, the locking sucker.

As shown in figs. 1 and 4, the handle 1 of negative pressure sucker is when pressing down, shell 7 by sucker compresses rubber plate 10 outer rings, drive the riser 9 of sucker bottom and the center of rubber plate 10 by sucker center lift shaft 6 simultaneously, compressing turriform spring 8 formation relative vacuum zones, lifting center, sucker produces negative pressure, thus absorption and being locked on the object of being inhaled, and locking back shape is as shown in Figure 2.

Shown in Fig. 2 and 4,12 while of the keyhole handle 1 that is inserted on the handle with private key 11 upwards promotes, and turriform spring 8 and rubber are pulled 10 and restored to the original state, and sucker 7 is opened voluntarily.Fix any object on sucker, as handle, pipe etc. then can be fixed or inhale the required object of fixing, moving, thereby finish whole adsorptive process by sucker.

Claims

1, a kind of lockable negative pressure sucker is characterized in that, is made up of pull bar, housing, rubber plate, spring and handle, convexes with a blind hole on the housing; Pull bar passes the confined space of housing and rubber plate formation, and an end is fixedlyed connected with the riser that is embedded in the rubber plate central position, and the other end links together by locating stud and handle; Spring housing is located on the pull bar.
