Abstract

The utility model discloses an improved sucker, which mainly comprises a soft sucker cover and a fixing device, wherein a conical table is arranged on the soft sucker cover. The improved sucker is characterized in that a stretching plate and a hard outer cover which penetrates through the stretching plate and is sleeved with the stretching plate are arranged on the soft sucker cover; a spring is sleeved on the stretching plate between a hard outer cover and a soft sucker; the fixing device comprises two crank shaft plates coupled with the stretching plate, two side straight edges and a lower cambered edge; the two crank shaft plates are parallel; one end of one crank shaft plate is connected with one end of the other crank shaft plate; the two side straight edges and the lower cambered edge are positioned outside the connection end of the two crank shaft plates; a groove is formed in one straight edge contacting the hard outer cover; a hook or a bracket is arranged at the connection end on the side faces of the crank shaft plates; a bulge is arranged on the inner side of the hook, which is close to the adhesive face of the sucker; the bulge and the outer edge of the soft sucker cover are positioned on the same horizontal plane; and a rubber sleeve is sleeved outside the bulge. The improved sucker has the advantages of simple structure, high practicability and the like.

Description

A kind of follow-on sucker

Technical field

The utility model relates to plastics five metals daily necessities fitting field, more particularly relates to a kind of follow-on sucker.

Background technique

At present, sucker in use generally all need push pelvic surface of sacrum, pressurized air; So that sucker cements, and sucker in use, often receives the relaxation shrinkage of material; Perhaps hang the pulling force influence of article, sucker comes off easily, has influenced the use of sucker-type hook or support greatly.

Summary of the invention

The purpose of the utility model is exactly in order to solve the deficiency of existing technology, and a kind of simple in structure, the follow-on sucker that adsorption force is stable that provide.

The utility model is to adopt following technical solution to realize above-mentioned purpose:

A kind of follow-on sucker mainly is made up of soft sucker cover and fixing device, is on the soft sucker cover to it is characterized in that the taper platform: this soft sucker cover is provided with drawing plate and the hard outer cover that passes this drawing plate and fit; On this drawing plate between hard outer cover and the soft sucker cover, also be with spring.

Said fixing device comprises two crankshaft cheeks that are coupling with drawing plate, the parallel and end connection of these two crankshaft cheeks, and outer both sides straight flange and the lower curved limit of connecting end on this crankshaft cheek, a straight flange that wherein contacts with the hard outer cover is provided with groove.

The connecting end of said crankshaft cheek side is provided with hook or support.

This hook is provided with convexity in the inboard near the sucker bonding plane, and the outer of this convexity and soft sucker cover is in a horizontal plane, and should convexity be socketed with gum cover outward.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:

The utility model is on existing sucker basis, to form through simple refit, and structure is very simple, and cost of production is low, during use because the rotation of crankshaft cheek; Make soft sucker flexible, the bonding or relieving with stationary plane is because the relaxation power of spring; When bonding, very firm, using effect is good.

Embodiment

Shown in Fig. 1-3, the follow-on sucker of the utility model mainly is made up of with fixing device soft sucker cover 1, is on the soft sucker cover 1 that taper platform, this soft sucker cover 1 are provided with drawing plate 2 and the hard outer cover 3 that passes this drawing plate 2 and fit; On this drawing plate between hard outer cover 3 and the soft sucker cover 1, also be with spring 4.Said fixing device comprises two crankshaft cheeks 5 that are coupling with drawing plate, these two crankshaft cheeks, 5 parallel and end connections, and outer both sides straight flange and the lower curved limit of connecting end on this crankshaft cheek 5, a straight flange that wherein contacts with hard outer cover 3 is provided with groove.The connecting end of said crankshaft cheek 5 sides is provided with hook 6.This hook 6 is provided with convexity in the inboard near the sucker bonding plane, and the outer of this convexity and soft sucker cover 1 is in a horizontal plane, and should convexity be socketed with gum cover outward.

Except hook structure, on the connecting end of said crankshaft cheek side support can also be set.

During use, as shown in Figure 3, soft sucker cover is in open configuration, and spring also is in extended state, at this moment end in contact on the side straight flange of crankshaft cheek and the hard outer cover; In the time of need being adsorbed on bonding plane, turning crankshaft plate and hook make the straight flange that has groove contact with the hard outer cover; Soft sucker cover shrinks, extrusion spring, and the crankshaft cheek groove ends is stuck in the taper platform upper end of hard outer cover; Sucker just can firmly be adsorbed on the stickup face like this, like Fig. 1.

The utility model is not limited to the foregoing description; The above preferred embodiment that is merely the utility model that shows; Can not limit the scope of the utility model with this; Therefore under the situation that does not break away from the utility model creation spirit, the equivalent variations of being done still belongs to the scope that the utility model is contained.
