Description

Adjustment type antenna joint chair package assembly

The utility model relates to a kind of adjustment type antenna, refers to a kind of adjustment type antenna joint chair package assembly especially.

The utility model indication adjustment type antenna is meant that this antenna can be that the different directions adjustment is done in the axle center with the pivoting point, and its joint chair more can be done circumferentially to rotate to adjust.This type of antenna structure is widely used on the electrical equipment of Source Music and so on, is also applied to now in the car on mobile phone or the general mobile phone.

This type of adjustment type antenna commonly used roughly is provided with a top joint chair for the movable antenna that articulates, and this joint chair is also located with other associated components.The novel patent case of known adjustment type antenna structure of this kind such as Taiwan the 82210828th " mobile phone antenna structure " is an example, below will cooperate this its structure of case constitutional diagram detailed explanation:

As shown in Figure 1, above-mentioned joint chair 10 roughly is provided with a vertical clip slot 11 and a radial direction through hole 12 and is provided with a bolt 15 movable bottom plat parts 14 that articulate antennas 13.Whole joint chair 10 is also located with package assembly 16, hollow screwed pipe 17, screw-jointing seat 18 and internal inductance coil 19.For making above-mentioned joint chair 10 can do revolution adjustment, this joint chair is provided with the top flanging 160 that is pressed against package assembly 16 by the end formed shoulder 100 of prominent ring for the tension force that cooperates inductance coil 19.This is one for making joint chair 10 can freely turn round the location structure of adjustment, can find out and to use more and complicated assembled component, simultaneously, because joint chair 10 bottoms are subjected to the axial vertical compression thrust of inductance coil 19, and making its resistance when the direction revolution adjustment of carrying out as shown by arrow A bigger, application of force adjustment has some setbacks.

The purpose of this utility model is promptly providing a kind of adjustment type antenna joint chair package assembly, and whole joint chair can be located with the structure of more simplifying, and in addition adjustment gyratory directions that can be more portable and smart.

A purpose more of the present utility model is providing a kind of adjustment type antenna joint chair package assembly, and its joint chair extension rod and resilient bushing are set at different inserting tightnesses with the more visual antenna heavy burden of medium pore state.

The purpose of this utility model is achieved in that

A kind of adjustment type antenna joint chair package assembly, this joint chair are provided with clip slot and the radial direction through hole that articulates antenna for movable, and it is characterized in that: joint chair is had the outrigger shaft of a suitable size diameter and length by the bottom face mediad; Other establishes a bearing, and this bearing is provided with the medium pore for the inserting outrigger shaft, the inserting of joint chair outrigger shaft in the bearing medium pore and in the bearing bottom with an extremity piece in conjunction with outrigger shaft bottom abutting end; Be situated between between joint chair outrigger shaft and the bearing medium pore and adorn a hollow tubular resilient bushing, the location joint chair is also allowed its revolution adjustment.

This resilient bushing is provided with complete ring up and down, a plurality of axial long slot bore on the stack shell.

The diameter that matches of this joint chair outrigger shaft and bearing medium pore is to set according to the stressed load condition of the mast that articulates.

After adopting technique scheme, clearly can simplify the location structure of this adjustment type antenna joint chair, make making or assembling all more quick and convenient, and, can make joint chair and more portable and smart when controlling adjustment with its movable mast that articulates because of the resilient bushing between joint chair outrigger shaft and bearing medium pore only has less level to reaction force.

Novelty of the present utility model and other characteristics will be tending towards clear in the detailed description that cooperates the following drawings embodiment, as shown in the figure:

Fig. 1 is an adjustment type antenna assumption diagram commonly used;

Fig. 2 is the utility model embodiment stereogram;

Fig. 3 is the element exploded view of Fig. 2;

Fig. 4 is the cross-section cutaway view of Fig. 2.

The number in the figure explanation:

20...... joint chair 21...... clip slot

22...... radial direction through hole 23...... bottom face

24...... abutting end at the bottom of the outrigger shaft 25......

30...... bearing 31...... medium pore

32...... top end face 33...... concave step surface

40...... extremity piece 50...... resilient bushing

51, complete ring 53...... long slot bore about the 52......

As shown in Figure 2, the utility model roughly also is provided with the joint chair 20 that articulates antenna for movable, and this joint chair 20 is combined in a bearing 30 surfaces, and in the bottom with an extremity piece 40 respectively this element give combination.Above-mentioned joint chair 20 is provided with vertical clip slot 21 equally and radial direction through hole 22 supplies to articulate antenna.

Now see also Fig. 3,4, this joint chair 20 is provided with a downward outrigger shaft 24 that extends suitable length and be made as suitable size diameter by bottom face 23, these outrigger shaft 24 default bottom abutting ends 25.And bearing 30 bodies can be made as and joint chair 20 sizable diameters, and default one medium pore 31 that is slightly larger than outrigger shaft 24.This bearing 30 preferably forms a concave step surface 33 by top end face 32 with a shallow degree of depth.Can combine with extremity piece 40 according to the end abutting end 25 of above-mentioned outrigger shaft 24, according to illustrated embodiment, this abutting end 25 be an external screw teeth, and extremity piece 40 then is provided with relative inner bolt hole 41, makes both combinations that can be spirally connected mutually, and both also can make up thought in the mode of closely cooperating.

When above-mentioned joint chair outrigger shaft 24 and bearing medium pore 31 insertings combination, can preset a resilient bushing 50 between the two, in preferred embodiment as shown, this resilient bushing 50 can be made hollow tubular with metal material, it contains

complete loop portions

51,52 up and down, and most axially long slot bores 53 of being located at stack shell.Whole resilient bushing 50 thereby can be when the mutual insertings combination of outrigger shaft 24 and medium pore 31, this lining 50 becomes elastic insert between the two, makes the joint chair 20 on the one hand can be with suitable tightness and bearing 30 combinations, and allows the revolution adjustment that these joint chair 20 works 360 are spent.

Because the mast that articulated of joint chair 20 may have different length and diameter, thereby the mast of these different types is understood clip slot 21 and the different stressed heavy burden state of through hole 22 formation at joint chair 20 with after joint chair engages.Joint chair package assembly of the present utility model can be to this in addition elasticity adapt to.For example,, the diameter of outrigger shaft 24 slightly can be amplified or bearing medium pore 31 is slightly dwindled, make both form tighter inserting state, use under this bigger stressed load and can adapt to if joint chair 20 articulates when length reaches heavier mast; Otherwise, then can adopt slightly the outrigger shaft 24 of diameter reduction or the medium pore 31 that slightly amplifies if when using short or lighter mast.

In the whole structure-improved of the utility model, not only member is less for it, and structure is also simplified, and therefore no matter makes or assemble all more quick and convenient.And the resilient bushing between joint chair outrigger shaft and bearing medium pore more only has less level to reaction force, it is more portable and smart when controlling adjustment to make that joint chair reaches with its movable mast that articulates, it really has value on actual utilization benefit and the industry, so mere formality proposes utility application in accordance with the law.
