Object of the present invention can also further realize by following technical measures.

Aforesaid Portable antenna mast, wherein said joint pin lower end is provided with axial flat recess, and joint pin lower end periphery is provided with the inverted L shape groove that axial groove turns radial slot, and the radial slot of described inverted L shape groove intersects vertically with axial flat recess; When upper pole, several middle pole and lower pole link into an integrated entity, limiting rivet is connected in the axial groove of inverted L shape groove.

Aforesaid Portable antenna mast, the axial groove oblique of wherein said axial flat recess and inverted L shape groove, the angle α of oblique is 83 °～85 °.

The present invention is simple and compact for structure, during installation, middle pole joint pin lower end is injected in lower pole upper end, the axial flat recess of joint pin lower end is aimed at the limiting rivet in lower pole, pole in pushing downwards, flexible connection mechanism pressurized, limiting rivet withstands on axial flat recess bottom land, then in rotation, pole nearly 90 is spent, hear that noise made in coughing or vomiting clatter sound represent that limiting rivet on lower pole slips in the axial groove of inverted L shape groove of middle pole joint pin, be that joint pin has hooked the limiting rivet on time pole, now, stage clip bounce-back compresses pillar, limited the rotation of joint pin and moved up and down, thereby dock to pole and lower pole fast and reliable in realizing, using the same method can be by upper pole, several middle poles, lower pole links into an integrated entity, easy to operate.The present invention can be as required by several middle poles assemblings or split into different length, combine versatile and flexiblely, be convenient to transportation and carry, lightweight, antiseptic property is good, long service life.

Advantage and disadvantage of the present invention, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structure for amplifying schematic diagram of joint pin of the present invention;

Fig. 3 is the A-A cutaway view of Fig. 2.

Embodiment

Below in conjunction with drawings and Examples, the invention will be further described.

As shown in FIG. 1 to 3, the present invention includes the base 1, lower pole 2, several end to end pole 3, the upper pole 4 on top, the joint pin 5 that are arranged in lower end, described joint pin 5 upper ends are separately fixed in upper pole 4 lower ends or middle pole 3 lower ends by rivet 9, and base 1 can be fixed on other positions of shelter bulkhead 10 or shelter.Upper pole 4, middle pole 3 are circular tube structure with lower pole 2, upper pole 4, several middle pole 3 link into an integrated entity by joint pin 5 respectively with lower pole 2, can length according to actual needs assemble and split, upper pole 4 upper ends are fixedly connected with upper flange 6, upper flange 6 is for fixed antenna, and the two can be threaded connection with upper pole 4 upper ends and upper flange 6, also can adopt grafting, a kind of mode before the present embodiment adopts, upper flange 6 can be according to different antenna size customizations.Lower pole 2 is fixedly connected with lower flange 7 by rivet 9, lower flange 7 is fixedly connected with base 1 by bolt, middle pole 3, in lower pole 2, be respectively equipped with flexible connection mechanism 8, flexible connection mechanism 8 comprises stage clip 81, be positioned at a pair of T-shaped retaining screw 82 of stage clip 81 upper and lower sides, horizontal on pipe and lay respectively at the limiting rivet 83 in T-shaped retaining screw 82 outsides, T-shaped retaining screw 82 can along in pole 3 or lower pole 2 slide up and down, upper pole 4, when several middle poles 3 link into an integrated entity with lower pole 2, limiting rivet 83 is connected in joint pin 5 lower ends, T-shaped retaining screw 82 upper ends are resisted against on joint pin 5 lower ends.

Joint pin 5 lower ends are provided with axial flat recess 51, and joint pin 5 lower end peripheries are provided with the inverted L shape groove 52 that axial groove turns radial slot, and the radial slot 521 of inverted L shape groove 52 intersects vertically with axial flat recess 51; When upper pole 4, several middle pole 3 link into an integrated entity with lower pole 2, limiting rivet 83 is connected in the axial groove 522 of inverted L shape groove 52, axial groove 522 obliques of axial flat recess 51 and inverted L shape groove 51, and the angle α of oblique is 83 °～85 °, in the present embodiment, angle α is 84 °.

During installation, the joint pin of middle pole 35 lower ends are put in lower pole 2 upper ends, the axial flat recess 51 of joint pin 5 lower ends is aimed at the limiting rivet 83 in lower pole 2, pushing joint pin 5, now stage clip 81 compressions, limiting rivet 83 withstands on axial flat recess 51 bottom lands, limiting rivet 83 is aimed at the radial slot 521 of inverted L shape groove 52 on joint pin 5 peripheries, then pole 3 in rotating, hear that noise made in coughing or vomiting clatter sound represent that limiting rivet 83 on lower pole 2 slips in the axial groove 522 of inverted L shape groove of joint pin 5, T-shaped retaining screw 82 is resisted against on joint pin 5 lower end surfaces, middle pole 3 links into an integrated entity by joint pin 5 and lower pole 2, limited the rotation of joint pin 5 and moved up and down, thereby dock to pole 3 and lower pole 2 fast and reliable in realizing, using the same method can be by upper pole 4, many middle poles 3, lower pole 2 links into an integrated entity.While removing the pole connecting, first push joint pin 5, limiting rivet 83 falls back on radial slot 521 from the axial groove 522 of the inverted L shape groove of joint pin 5, then pole 3 in rotating, limiting rivet 83 falls back in the axial flat recess 51 of joint pin 5, just can extract middle pole 3, with the connection between separated each pole of such method.

Upper pole 4 of the present invention, middle pole 3, lower pole 2 all adopt aluminum pipe to make, and joint pin 5 adopts aluminium bar to make, and lightweight, antiseptic property is good.

In addition to the implementation, the present invention can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
