Abstract

The utility model discloses a suction cup assembly, comprising a casing, a suction cup, a connecting rod, a screw rod, and a wing-shaped screw nut, wherein, the bottom of the campanulate casing is provided with the suction cup. The suction cup in the casing is connected with the screw rod which extends through the top of the casing by the connecting rod. The screw rod is joined with the wing-shaped screw nut, on the top of the casing. The wing-shaped screw nut is screwed to pull the suction cup for enhancing the sorption strength.

Description

Suction cup assembly

Disk taper sucker by soft rubber is made utilizes the effect of pull of vacuum and atmospheric pressure, and the sucker center is upwards lifted, and its adsorption strength is strengthened, to promote the practical effect on using.

The primary and foremost purpose of the utility model is to provide a kind of Suction cup assembly, by applying pressure to the sucker periphery, and the sucker center is upwards lifted to strengthen its adsorption strength, to promote the practical effect on using.

Time purpose of the utility model is to provide a kind of Suction cup assembly, by bell housing play dual parts simultaneously to compress the sucker periphery and as the center lifting rod upwards lift against, to obtain dual enhancing benefit.

For reaching above-mentioned purpose, the utility model includes shell, sucker, connecting rod, screw rod, wing nut etc.; Wherein, sucker places bell housing bottom end opening place, its periphery is compressed by the shell aperture edge, it is in central link one connecting rod of enclosure, mat connecting rod connecting screw rod, screw rod runs through the shell top and engages with packing ring and wing nut, and mat is tightened wing nut and lifted the sucker center and compress the sucker periphery simultaneously, thereby strengthens adsorption strength.

Now with regard to detailed content of the present utility model, feature and effect for an embodiment and be described with reference to the accompanying drawings as follows:

Fig. 1 is the perspective exploded view of the utility model;

Fig. 2 is the perspective view of the utility model;

Fig. 3 is the sectional view of the utility model in free state;

Fig. 4 is the sectional view of the utility model in the sucker depressed state.

Fig. 5 is the utility model is upwards lifted state at sucker a sectional view.

Consult Fig. 1 and Fig. 2, the utility model system is made of sucker 2, connecting rod 18, screw rod 14, shell 1 and wing nut 13 etc.; Wherein, sucker 2 is by the soft rubber moulding, and is in the form of annular discs, the center raises up, on establish the pressure edge 20 of tool T shape caulking groove, and can have protruding grain (burr) 22 on these sucker 2 back sides, or dimpled grain (groove) 23, also can on periphery, establish the interrupted fin 24 or the bulge loop 25 that raise up;

Connecting rod 18 is round bar shape, and the interior flange 19 of T shape caulking groove in the flange 20 that adapts to sucker 2 is formed on the bottom;

Screw rod 14 is formed with the embedding seat 15 adaptive with connecting rod 18 in the bottom, establish a screw 16 on the embedding seat 15 and be screwed into for screws 17;

Shell 1 is bell, and bottom open end extends into and compresses edge 11, and an open-work 10 is established on the top;

The flange 19 of connecting rod 18 is embedded in the T shape caulking groove in the flange 20 of suckers 2, connecting rod 18 embeds in the bottom embedding seat 15 of screw rod 14 and with screw 17 again and fixes, screw rod 14 inserts from the bottom open end of shell 1 then, pass top open-work 10, load onto packing ring 12 and wing nut 13, be assembled into Suction cup assembly as shown in Figure 3.

Shown in Fig. 4 and 5, the periphery of sucker 2 is subjected to the opening end of shell 1 to compress edge 11 to compress, by wing nut 13 top of screw rod 14 with respect to shell 1 upwards lifted, thereby lift connecting rod 18, and then the center flange 20 of sucker 2 up lifted, strengthening the pull of vacuum of sucker 2, and when screw rod 14 upwards lifts sucker 2, shell 1 is also compressing the periphery that edge 11 compresses sucker 2, and reaches the effect that adsorption strength is promoted in expection.

And, because the back side of sucker 2 or periphery are provided with concave, convex grain (line) 22,23 or fin 24, bulge loop 25, increase shell 1 compress edge 11 compress intensity the time can not slide, strengthen the adsorption strength of sucker 2.

In sum, the utility model provides a kind of tool to strengthen the Suction cup assembly of sucker adsorption strength, and it constructs still unexposed in the prior art mistake, thereby has patentability.

Claims

1, a kind of Suction cup assembly comprises members such as shell, sucker, connecting rod, screw rod, wing nut; It is characterized in that this sucker places bell housing bottom end opening place, periphery is compressed by the shell aperture edge, it is in central link one connecting rod of enclosure, the mat connecting rod connects a screw rod, screw rod runs through the shell top, this screw rod engages with wing nut with packing ring in outside, shell top, and mat is tightened wing nut and lifted the sucker center and compress the sucker periphery simultaneously, thereby strengthens adsorption strength.

2,, it is characterized in that to have on this sucking disc back side protruding grain, burr or groove, dimpled grain, or be provided with interrupted fin or the bulge loop that raises up in the sucker periphery by the described Suction cup assembly of claim 1.
