Description

Magnetic chuck and use the antenna of this magnetic chuck

Technical field

The utility model relates to a kind of magnetic chuck and uses the antenna of this magnetic chuck, this antenna can power that sub-communication product uses as wireless receiving or sender and by magnetic chuck absorption, inhale magnetic on metal or nonmetal object plane.

Background technology

Conventional suction cups is to produce the vacuum adhesion effect by pressing down behind the air of getting rid of the bottom surface, makes magnetic that sucker can be firm on flat surface.

Tradition is used to receive the external antenna of digital signal again, and its bottom is fixed on the object by modes such as lock spiral shell, anchor clamps, magnet, suckers, but that the lock spiral shell needs in advance on object boring to cause body surface to be forced to is bad; And anchor clamps easily injure body surface or lacquer painting; Magnet can only be inhaled magnetic in but not inhaling magnetic on the metal object plane on nonmetal object plane; Though sucker can be adsorbed on flat surface, can't adsorb for a long time; Therefore, external antenna fixedly still has many problems.

Above-mentioned external antenna is secured on the object plane by sucker and magnet, but sucker and magnet are not that common structure is implemented for separating use; In other words, desire when the nonmetal smooth body surface, must be used antenna installation in sucker, can not use magnet to implement, otherwise desire when the metal object surface, must be pulled down antenna installation with sucker and changes magnet into and implement; Because sucker and magnet can not be total to structure and implement, so can not reach the effect of " dual sharing ", therefore how to overcome this problem points, just become the problem points that this novel desire solves.

The utility model content

The purpose of this utility model be to provide a kind of can suck in the plane or magnetic at lip-deep magnetic chuck of metal object and the antenna that uses this magnetic chuck, this antenna can be easy to make, reduce cost, have more splendid impedance matching and good reception function, and can be easy to folding and carry.

The utility model is to adopt following technological means to realize:

One soft colloidality awl dish; And a magnetic bolt dish, having magnetic and be hidden in the above-mentioned soft colloidality awl dish, its magnetic property penetrates soft colloidality awl dish and metal is produced the magnetic effect.

According to above-mentioned magnetic chuck, wherein, soft colloidality awl dish comprises an arc positioning disk that expands face, and one-body molded outstanding again protective disc on the arc positioning disk.

According to above-mentioned magnetic chuck, wherein, magnetic bolt dish is to go up to be bolt, is fixed disk down, and both are one-body molded combinations, and bolt exposes on protective disc again, and fixed disk is to be hidden in the protective disc.

The antenna of this novel use magnetic chuck is achieved in that

One magnetic chuck, by a soft colloidality awl dish, and one have magnetic and the magnetic bolt dish that is hidden in the above-mentioned soft colloidality awl dish is formed, the magnetic property of this magnetic bolt dish penetrates soft colloidality awl dish and to metal generation magnetic effect;

One cladding, for hollow tube and be arranged on the above-mentioned magnetic chuck, and top, two ends, the end all have perforate;

One coaxial cable; One end is as first end that receives signal, end is second end as output signal in addition, this coaxial cable by the cladding clamping, make aforementioned first end be exposed on the cladding outward, this first end comprise one section expose and outer conductor, one section that reflexed is coated on the external insulation layer periphery expose inner insulating layer outside aforementioned outer conductor, and one section outside be exposed at inside conductor outside the aforementioned inner insulating layer;

One connector is connected above-mentioned coaxial cable second end and is used for any plug joint as signal output usefulness.

According to above-mentioned antenna with magnetic chuck, wherein, soft colloidality awl dish lower end is the arc positioning disk of expansion face, has one-body molded and outstanding protective disc on positioning disk.

According to above-mentioned antenna with magnetic chuck, wherein, protective disc has vertical axis hole and vertically inserts to hold cladding, and protective disc has side opening and passes to hold coaxial cable again.

According to above-mentioned antenna with magnetic chuck, wherein, have open lateral sulcus on the protective disc, this lateral sulcus is communicated with vertical axis hole, and the cladding bottom is pivoted by the lateral shaft bolt, it can be rotated between axis hole and dissected valley change angle.

According to above-mentioned antenna with magnetic chuck, wherein, cladding is earthy metal tube.

According to above-mentioned antenna with magnetic chuck, wherein, cladding is the insulation rubber tube that beautifies usefulness.

The utility model is compared in prior art, has following remarkable advantages and beneficial effect:

After one was penetrated wrap molding, this soft colloidality awl dish was coating the fixed disk of magnetic bolt dish to magnetic chuck by magnetic bolt dish and soft colloidality awl dish, because it is moderate to coat thickness, so can not influence the external magnetic effect of magnetic bolt dish.

Because the bottom of antenna combines magnetic chuck, so its energy vacuum is attached on the nonmetallic flat surface, also can magnetic on irregular metal object plane, really reach the implementation result of " dual sharing ", owing to do not need must select sucker or one of them enforcement of magnet as tradition, tradition is more convenient so use is gone up.

When the magnetic chuck magnetic was on the metal object plane, can be made soft colloidality awl coil firmly by magnetic vacuum suction can more can reach long magnetic effect than conventional suction cups then on object plane again.
