Abstract

A fixing device used in the vehicle-mounted navigation device comprises a bracket at one end of which a fixed rear cover is arranged, a fixed front cover, a rotary seat and a groove, wherein one end of the fixed front cover is connected with the fixed rear cover, and a plurality of openings are formed on the other end surface of the fixed front cover; the rotary seat is arranged at the periphery of the fixed front cover and fixed between the fixed front cover and the rear cover, and a plurality of first magnetizers are arranged on the inner side of the rotary seat, closely correspond to the opening , and can be rotated at the periphery of the fixed front cover along the rotary seat; the groove is formed on the navigation device, and a plurality of second magnetizers are arranged in the groove and are matched with and placed in the opening; and at least one of the first magnetizers and the second magnetizers adopt magnets. The fixing device can facilitate the disassembly of the navigation device without influencing the aesthetic sense of the appearance and the vision of the driver.

Description

Anchor fitting

[technical field]

The utility model relates to a kind of anchor fitting, particularly a kind of anchor fitting that is applied in the on-vehicle navigation apparatus.

[background technology]

The fast development of mobile communication makes modern life rhythm more and more faster, and the update of mobile communication product and market fight are also more and more strong.A large amount of navigational aid is emerged in large numbers on market, as: have PDA, PND, GPS of navigation feature etc., and these navigational aid have obtained a large amount of application on the vehicle such as automobile, train, aircraft.General used navigational aid is installed in the car interior trim by a fixed support on the automobile now.Because of navigational aid various in style, so just need on the variety classes support support that navigational aid is carried in support to connect frame.Existing homing advice fixed support generally all fixes homing advice with manner, existing fastening direction can be divided into: (1) is vertical to fasten, homing advice fastens with support from top to bottom, the shortcoming of this mode is the Windshield collision of easy and car, especially when taking off homing advice, exert oneself to be easy to bump against after excessive with windshield; (2) horizontal shutting, homing advice fasten with fixed support from front to back, and the shortcoming of this mode is that the fixed support area is excessive, and after homing advice took off, because of the excessive vision that influences of support bracket fastened area, and its external form was more scrappy not attractive in appearance.

In view of this, be necessary to propose a kind of anchor fitting in fact, utilize the magnetic force manner of the rotatable magnet of this anchor fitting to realize dismounting homing advice in a horizontal manner, and the fixed support in this anchor fitting and homing advice external form are irrelevant, can make external form less, attractive in appearance.

[summary of the invention]

Therefore, the purpose of this utility model is to provide a kind of homing advice easy to assemble and fixed anchor fitting.

For achieving the above object, the utility model provides a kind of anchor fitting, and it is applied in the on-vehicle navigation apparatus, and this anchor fitting comprises:

A support, the one end is provided with fixedly bonnet;

A fixing protecgulum, the one end is connected with the said fixing bonnet, and this fixedly is provided with several openings in the other end of protecgulum;

A rotary seat, it is located at the peripheral of said fixing protecgulum and places fixedly protecgulum and fixedly between the bonnet, this rotary seat inboard is provided with several first magnetizers, and this first magnetizer is corresponding and mutually close with above-mentioned opening, these some first magnetizers with rotary seat in that fixedly protecgulum is peripherally pivoted;

A groove, it is located on the above-mentioned homing advice, is provided with several second magnetizers in this groove, and this second magnetizer and above-mentioned opening match to merge and place opening;

Wherein, one of them is a magnet at least for above-mentioned first magnetizer and second magnetizer.

Especially, the said fixing protecgulum and fixedly bonnet link together in the mode of bottle screw.

Especially, the said fixing protecgulum and fixedly bonnet link together in the mode of buckle.

Especially, the outside of above-mentioned rotary seat also is provided with screw thread or several recesses.

Compared to prior art, anchor fitting of the present utility model has realized that by having increased magnetizer on rotary seat and the homing advice homing advice controls in the mode of magnetic force when the dismounting, reach easy-to-dismount purpose, more can not influence aesthetic appearance and driver's vision.

For the purpose of this utility model, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[specific embodiment]

With reference to Fig. 1, Fig. 2, shown in Figure 3, in present embodiment, it is applied to anchor fitting of the present utility model in the on-vehicle navigation apparatus 1, and this anchor fitting comprises:

A support 10, one end are provided with fixedly bonnet 101, this fixedly the inwall of bonnet 101 be provided with some negative threads 1011;

A fixing protecgulum 20, the one end is provided with some outside threads 201 and matches with negative thread 1011 on the said fixing bonnet 101 and links together, and this fixedly is provided with three openings 202 (this opening 202 can be a plurality of) and center position also is provided with a circular hole 203 in the other end of protecgulum 20;

A rotary seat 30, it is located at the peripheral of said fixing protecgulum 20 and places fixedly protecgulum 20 and fixedly between the bonnet 101, these rotary seat 30 inboards are provided with three first magnetizers 301, this first magnetizer 301 is the magnetic post, this first magnetizer 301 is corresponding and mutually close with above-mentioned opening 202, this first magnetizer 301 along with rotary seat 30 in that fixedly protecgulum 20 is peripherally pivoted, these rotary seat 30 outsides also are provided with several recesses 302, this recess 302 can make things convenient for the driver to rotate this rotary seat 30;

A groove 40, it is located on the above-mentioned homing advice, be provided with three second magnetizers 401 in this groove 40, this second magnetizer 401 is an iron prop, this second magnetizer 401 matches to merge with above-mentioned opening 202 and places opening 202, and inhale mutually with above-mentioned first magnetizer 301, the center position of this groove 40 also is provided with a cylinder 402, and it places circular hole 203 and matches with it.

In present embodiment, fixedly protecgulum 20 in this anchor fitting links together with fixing bonnet 101, and the centre is provided with rotary seat 30, this rotary seat 30 can freely rotate in said two devices, when homing advice is installed, only need second magnetizer 401 that homing advice is provided with is aimed at opening 202, when the two is close mutually, this second magnetizer 401 can be inhaled mutually with first magnetizer 301 on the rotary seat 30, thereby make homing advice be fixed on fixedly on the protecgulum 20, when the dismounting homing advice, only need rotate rotary seat 30 gently, at this moment first magnetizer 301 can rotate along with rotary seat 30, after rotating to an angle, first magnetizer 301 and second magnetizer 401 be mutually away from making the magnetic force between the two diminish, and at this moment the driver can be easily takes off homing advice from fixing protecgulum 20.
