Description

A kind of sucker

Technical field

This utility model relates to sucker, the sucker of a kind of convenient dismounting.

Background technology

Sucker is a kind of difference utilizing inside and outside atmospheric pressure, the absorption a kind of suspension member on object.Can be by sucker suction At smooth surfaces such as glass, ceramic tile, timber, under atmospheric pressure, sucker fixedly secures on smooth surface, but when needing When being taken off from smooth flat by sucker, need to stretch into the joint portion of band sucker and surface with finger or sharp-pointed instrument, Making the air pressure inside and outside sucker basically identical, sucker could split away off from smooth surface；Especially on moist surface, as defended Metope between life, due to the existence of steam, causes sucker to be more difficult to from metope and takes off.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of sucker, its convenient dismounting, simple in construction, convenient suspension Article.

For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of sucker, including discoid sucker body and company The hard circle tube neck part being connected on sucker body and the cylindrical shape sealed end being connected with cervical region, cervical region and the equal edge of sealed end The axis of sucker body is installed, and in the middle part of sealed end, the axis along sucker body is provided with the first through hole, along suction in the middle part of cervical region The axis of dish body is provided with the second through hole, and sucker body is connected with air by the second through hole and the first through hole；Sealed end External diameter is big compared with the external diameter of cervical region；The sealing-plug being closely assembled in the first through hole it is provided with at sealed end.

Improving further, described sealing-plug includes the chock plug stretching into described first through hole and the Handheld Division being connected with chock plug, Hand-held sealing-plug is facilitated to seal the first through hole.

Improving further, the cross section of described sealing-plug is T-shaped, it is simple to sealing-plug and sealed end fitted seal, prevents Air enters in suction cup main body from the first through hole.

Improving further, described sealed end outer peripheral face is additionally provided with external screw thread, is threaded connection a sealing lid, carries further The sealing of highly dense end-blocking, and the convenient connection sealing lid and sealed end.

Improving further, the described medial surface sealing lid is provided with a groove, and groove is built with the rubber for sealing sealing-plug Cushion rubber, increases the air-tightness of sealing-plug, keeps sucker suction in the fastness of smooth flat.

Improving further, the described lid that seals is connected on sealed end by a connection band, the convenient management sealing lid and receipts Receive.

This utility model include discoid sucker body and the hard circle tube neck part that is connected on sucker body and with The cylindrical shape sealed end that cervical region is connected, sucker body is connected with air, at sealed end by the second through hole and the first through hole It is provided with the sealing-plug being closely assembled in the first through hole, enters sucker by opening sealing-plug air from the first through hole and the second through hole Main body, suction cup main body inner and outer air pressure is consistent, and suction cup main body comes off from smooth flat, simple in construction, convenient dismounting；Sealed end External diameter is big compared with the external diameter of cervical region, suspended item at cervical region, convenient use.

Detailed description of the invention

With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1 to Figure 3, a kind of sucker, including discoid sucker body 1 He being made up of rubber or flexible plastic The hard circle tube neck part 2 being connected on sucker body 1 and the cylindrical shape sealed end 3 being connected with cervical region 2, cervical region 2 and close End-blocking 3 is all installed along the axis of sucker body 1, and the external diameter of sealed end 3 is big compared with the external diameter of cervical region 2, suspended item at cervical region 2, Convenient use.In the middle part of sealed end 3, the axis along sucker body 1 is provided with the first through hole 31, along sucker body in the middle part of cervical region 2 The axis of 1 is provided with the second through hole 21, is connected with air with the first through hole 31 by the second through hole 21, is provided with tightly at sealed end 3 It is assemblied in the sealing-plug 4 in the first through hole 31.Suction is entered from the first through hole 31 and the second through hole 21 by opening sealing-plug 4 air Disc main body 1, suction cup main body 1 inner and outer air pressure is consistent, and suction cup main body 1 comes off from smooth flat, simple in construction, convenient dismounting.

The cross section of sealing-plug 4 is T-shaped, including stretching into the chock plug 41 of the first through hole 31 and hand-held with what chock plug 41 was connected Portion 42, chock plug 41 makes sealing-plug 4 and sealed end 3 fitted seal, prevents air from entering in suction cup main body from the first through hole 31；Hand-held The existence in portion 42 makes sealing-plug 4 be easy to open.

Sealed end 3 outer peripheral face is additionally provided with external screw thread 32, is threaded connection a sealing lid 5, improves sealed end 3 further Sealing, the convenient connection sealing lid 5 and sealed end 3.Seal lid 5 to be connected on sealed end 3 by a connection band 51, facilitate close The management of capping 5 and storage.Sealing lid 5 medial surface and be provided with a groove 52, groove 52 is built with the rubber for sealing sealing-plug 4 Circle 53, increases the air-tightness of sealing-plug 4, keeps sucker suction in the fastness of smooth flat.

Below being only one preferred embodiment of this utility model, those skilled in the art is equal to by claim work Change the protection domain both falling within this case.
