Abstract

The utility model relates to an antenna that is able to endure the sway, comprising a mainstay body, one end of which is connected with components in interior of the electronic device which uses the antenna and other end is projected in the shell of the electronic device. One narrow groove is arranged in the middle part of the convex end. The mainstay body is a hollow cylinder and the interior of the mainstay body is provided with a rubbing part, a spring part and a fixing part. Wherein, one end of the rubbing part projects into the narrow groove and the other end is connected with the spring part. Besides, the fixing part makes the spring part and the rubbing part fixedly arranged in the mainstay body, and the spring part is often in the compression state. The antenna device also consists of an antenna body which is connected with the mainstay body. Besides, the middle part of one end that is formed by the antenna body and the mainstay body is projected and forms an abutting plate in order to be corresponding to the narrow groove on one end of the mainstay body. The antenna body is connected with the mainstay body through a pivot, and the abutting plate is hinged in the narrow groove and counterbalances the rubbing part so that the rubbing part closely pushes against the sole board of the abutting plate under the spring and then produces relatively strong friction and the body of the antenna can be positioned randomly after a plurality of times sway.

Yet, along with antenna body 10 waves increasing of number of times, the abrasion of buttcover plate 23, pivot 11 and

metallic gasket

21,22 will make between buttcover plate 23 and the screw body 11 and antenna body 10 and first metallic gasket 21, second metallic gasket 22 between frictional force reduce gradually, can't bear the gravity of antenna body 10 at last, rotate freely downwards around pivot 11 when causing that antenna body 10 stayed in a certain angle, antenna body 10 positions can't be fixed, and receive and useful life so that influence the signal of communication equipment.

[summary of the invention]

In view of above problem, the purpose of this utility model is to provide a kind of anti-antenna assembly that waves, can't location defect after repeatedly waving to solve existing antenna.

In order to achieve the above object, the utility model provides a kind of antenna assembly, comprise a Body of pillar, this Body of pillar is connected with the case of electronic device that uses this antenna, and an end of this Body of pillar links to each other with the element that uses this electronic installation inside, the other end then protrudes this case of electronic device, the middle part, protruding end is provided with a slit, this Body of pillar is a hollow cylinder, its inside is provided with a friction member, one elastomer and a fixture, this friction member one end protrudes in the slit, and the other end is connected with single spring, this fixture is fixed in this friction member and this elastomer in the Body of pillar, and this elastomer is in compressive state usually; This antenna assembly also comprises an antenna body, this antenna body links to each other with Body of pillar, the end middle part that links to each other is protruded and is formed a buttcover plate, with corresponding with the slit of Body of pillar one end, antenna body links to each other with Body of pillar by a pivot, make antenna body Body of pillar rotation relatively, the buttcover plate pivot is in slit and inconsistent with friction member, so friction member is subjected to can tightly replacing the antenna body bottom surface behind the elastic force, thereby produce bigger frictional force, make antenna body after repeatedly waving, still can arbitrarily be positioned a certain angle around pivot.

Compare with technology is arranged now, the utility model still can make Antenna Positioning in a certain angle through after repeatedly waving, and has overcome existing antenna and easily freely topple over and influence the defective of signal reception after repeatedly waving, thereby prolonged the useful life of antenna.The utility model is simple in structure, and it is long to be easy to processing and life-span, has practicality widely, can strengthen the competitiveness of product in market.
