Description

Sucker

Technical field

The utility model relates to a kind of sucker being adsorbed in wall.Belong to daily living article technical field.

Background technique

Existing sucker, be widely used in daily life, sucker is pressed on smooth wall by people usually, the air of draining between sucker and wall, then knob is rotated, thus make sucker be adsorbed on wall by suction function, above-mentioned sucker has the following disadvantages: (1) is due to Long-Time Service, the disk body of sucker can be out of shape, disk body and wall is caused not to fit completely, easily space is produced between disc perimeter and wall, cannot hook clothing etc. for a long time, easily come off.(2) thickness of the disk body of existing sucker is thin, and grip is inadequate, and the suction of sucker so also can be caused poor.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of sucker, and this kind sucker is thicker, grip large and long service life.

The purpose of this utility model is achieved in that

A kind of sucker, comprise plastic disk and fixed tray, plastic disk is coated on fixed tray, and fixed tray comprises threaded stem, basal disc and reinforced sheet, and one end of described threaded stem is fixed on basal disc, and the other end stretches out plastic disk, and described reinforced sheet is evenly arranged on the surrounding of basal disc.

A kind of sucker of the utility model, the edge of reinforced sheet is provided with two projections positioned opposite, and described projection is L-type, and the middle part of reinforced sheet is provided with three salient points.

A kind of sucker of the utility model, its sucker also comprises gland, and the center of gland has the hole with shaft, and threaded stem stretches out the perforate at gland center, and the part that threaded stem stretches out coordinates with nut, and the outer wall of gland and plastic disk is fitted.

A kind of sucker of the utility model, its plastic disk adopts plastic material to make, and fixed tray adopts plastic materials to make.

Compared with prior art, the beneficial effects of the utility model are:

1. a kind of sucker of the utility model, have the fixed tray with reinforced sheet in plastic disk, reinforced sheet can improve the intensity of the disk body of sucker, makes the long service life of sucker.

2. a kind of sucker of the utility model, it is protruding that the edge of reinforced sheet is provided with two L-types positioned opposite, and the middle part of reinforced sheet is provided with three salient points, and L-type projection effectively can improve the thickness of disk body, coordinates three salient points can increase the grip of disk body greatly.

Embodiment

See Fig. 1-5, the utility model relates to a kind of sucker, it comprises plastic disk 1, fixed tray 2 and gland 3, plastic disk 1 adopts plastic material to make, fixed tray 2 adopts plastic materials to make, plastic disk 1 is coated on fixed tray 2, described fixed tray 2 comprises threaded stem 2.1, basal disc 2.2, reinforced sheet 2.3, threaded stem 2.1 is provided with screw thread, one end of described threaded stem 2.1 is fixed on basal disc 2.2, the other end stretches out plastic disk 1, described reinforced sheet 2.3 is evenly arranged on the surrounding of basal disc 2.2, the edge of described reinforced sheet 2.3 is provided with two protruding 2.3.1 positioned opposite, described protruding 2.3.1 is L-type, the middle part of reinforced sheet 2.3 is provided with three salient point 2.3.2.

The center of described gland 3 has the hole coordinated with threaded stem 2.1, and threaded stem 2.1 stretches out the perforate at gland 3 center, and the part that threaded stem 2.1 stretches out coordinates with nut, and gland 3 is fitted with the outer wall of plastic disk 1.

Mounting type: fixed tray 2 is placed in special mould, plastic to fixed tray 2, fixed tray 2 surrounding forms plastic disk 1, finally gland 3 is arranged on the outer wall of plastic disk 1,

During use, be first fitted on wall by the inwall of plastic disk 1, then tightening nuts, threaded stem 2.1 pulls out and plastic disk 1 is out of shape, and under the effect of negative pressure, plastic disk 1 is tightly attached on wall.

Owing to there being the fixed tray 2 with reinforced sheet 2.3 in plastic disk 1, reinforced sheet 2.3 can improve the intensity of the disk body of sucker, makes the long service life of sucker; The edge of reinforced sheet 2.3 is provided with two protruding 2.3.1 of L-type positioned opposite, and the middle part of reinforced sheet 2.3 is provided with three salient point 2.3.2, and the protruding 2.3.1 of L-type effectively can improve the thickness of disk body, coordinates three salient point 2.3.2 can increase the grip of disk body greatly.
