[0035] like Figure 1-10 As shown, the antenna is described in detail:

[0036] An antenna includes a line body 101, a base 102 and a mounting base 201. The base 102 is arranged at the lower end of the line body 101, and the base 102 can be detachably installed in the mounting base 201. Clamping frames are symmetrically rotated at both ends of the mounting base 201. The two clamping frames can be clamped and fixed on the beam column to fix the line body 101.

[0037] The wire body 101 is the main body of the converter, and the base 102 is used to support the wire body 101. When the wire body 101 needs to be installed and fixed on a cylindrical beam, the base 102 is installed in the mounting seat 201, and then the two clamping frames are rotated to clamp the two clamping frames on the beam to fix the wire body 101, so that the antenna can adapt to complex environment installation and fixation.

[0038] like Figure 8-10 As shown:

[0039] The clamping frame includes a transverse axis 401 rotating on the mounting seat 201 and arm plates 402 symmetrically fixed at both ends of the transverse axis 401 . A worm 404 rotates on the mounting seat 201 , and the worm 404 is meshed with the worm wheel on the transverse axis 401 for transmission.

[0040] When the wire body 101 needs to be installed and fixed on a cylindrical beam, the mounting base 201 is placed on the beam, and then the worm 404 is rotated to rotate the horizontal shaft 401 through the meshing of the worm 404, thereby driving the two support arm plates 402 to rotate, and then the two pairs of support arm plates 402 at both ends of the mounting base 201 are rotated relative to each other, thereby buckling on the horizontal shaft 401, and completing the fixation of the wire body 101 on the beam.

[0041] Further:

[0042] The clamping frame also includes a middle seat 501 installed between the two support arm plates 402, and the middle seat 501 extends away from the mounting seat 201 and has two lower clamping plates 502, and a cross bar 601 is rotated on the two lower clamping plates 502, and two upper clamping plates 506 are rotated on the cross bar 601, and a clamping shaft 507 is slid through a long hole 509 on the two upper clamping plates 506, and an adjusting screw 508 is rotated in the middle of the clamping shaft 507, and the adjusting screw 508 passes through the middle seat 501 and is threadedly connected to the middle seat 501.

[0043] When the rotating worm 404 drives the two arm plates 402 to rotate, the two arm plates 402 will drive the two lower clamping plates 502 and the two upper clamping plates 506 to rotate through the middle seat 501, so that the two groups of lower clamping plates 502 and upper clamping plates 506 on the two middle seats 501 are moved towards each other, and then the beams and columns are clamped by the lower clamping plates 502 and the upper clamping plates 506, replacing the arm plates 402 to clamp the beams and columns. Since each group of lower clamping plates 502 and upper clamping plates 506 is open, the clamped beams and columns can be more stable.

[0044] Moreover, by rotating the adjusting screw 508, the thread between the adjusting screw 508 and the middle seat 501 will cause the adjusting screw 508 to move axially on the middle seat 501. Since the two ends of the clamping shaft 507 respectively slide in the long holes 509 opened on the two upper clamping plates 506, when the adjusting screw 508 moves axially, the clamping shaft 507 will be driven to move accordingly, and then the two ends of the clamping shaft 507 will slide in the long holes 509 opened on the two upper clamping plates 506, so that the two upper clamping plates 506 can rotate on the cross bar 601, and then change the angle between the lower clamping plate 502 and the upper clamping plate 506, so that the antenna can adapt to the clamping installation of beams and columns with different diameters.

[0045] Further:

[0046] A plurality of star-shaped holes 403 are evenly arranged on the support arm plate 402, control frames 503 are slidably arranged at both ends of the middle seat 501, triangular blocks 504 are fixed on the outer sides of the two control frames 503, and springs I 505 are arranged between the two control frames 503 and the middle seat 501 to push the control frames 503 to both sides, so that the two triangular blocks 504 are respectively inserted into the corresponding star-shaped holes 403 to complete the installation of the middle seat 501.

[0047] The middle seat 501 is provided with a mounting groove at the end away from the lower clamping plate 502, and the two control frames 503 respectively penetrate the two sides of the mounting groove, and the inner ends of the two control frames 503 are fixed with limiting plates for limiting the control frames 503 to prevent the control frames 503 from slipping off the middle seat 501 when the spring I 505 pushes the control frames 503 to move outward.

[0048] The middle seat 501 will push the control frame 503 and the triangular block 504 to move away from the middle seat 501 through the elastic force of the spring I 505, so that the triangular block 504 is inserted into the corresponding star-shaped hole 403, thereby completing the fixation of the middle seat 501 and the support arm plate 402. When it is necessary to cooperate with the worm 404 to drive the two support arm plates 402 to rotate and adjust the opening directions of the two sets of lower clamping plates 502 and upper clamping plates 506, the two control frames 503 can be pressed simultaneously to approach the middle seat 501, and then the two triangular blocks 504 are disengaged from the two star-shaped holes 403, and then the middle seat 501 is rotated to adjust the angle between the two triangular blocks 504 and the star-shaped holes 403, and then the two control frames 503 are loosened to insert the two triangular blocks 504 into the two star-shaped holes 403 again, and the opening directions of the lower clamping plates 502 and the upper clamping plates 506 are changed, so as to adapt to complex installation environments and fix the antenna;

[0049] The triangular block 504 is a convex block with three pointed tips evenly arranged around the periphery, and the star-shaped hole 403 is a through hole with a plurality of pointed grooves evenly arranged on the edge, and the number of the pointed grooves is an integer multiple of three, so as to ensure that the three pointed tips of the triangular block 504 can be smoothly inserted into the star-shaped hole 403, and then, by changing the three pointed tips of the triangular block 504 to correspond to the three pointed grooves in the star-shaped hole 403 in a clockwise or counterclockwise manner, the relative angle between the triangular block 504 and the support arm plate 402 can be changed and adjusted by a certain angle;

[0050] At the same time, since the two arm plates 402 on the same side are both provided with a plurality of star-shaped holes 403, the installation position of the triangle block 504 can also be adjusted to further adapt to a complex installation environment, and the height of the antenna can be adjusted at the same time;

[0051] Furthermore, the cross bar 601 also slides in the long holes 509 opened on the two upper clamping plates 506. The outer ends of the two upper clamping plates 506 on the same side are transversely fixed with a cross plate 602. A round block runs through the middle of the cross bar 601. A tension spring 603 is provided between the cross plate 602 and the round block. Through the tension of the tension spring 603, the cross bar 601 will press against the outer ends of the long holes 509, so that the two upper clamping plates 506 extend inward to the longest state.

[0052] When the two upper clamping plates 506 are extended inward to the longest state, the matching triangular block 504 is located in the farthest star-shaped hole 403 on the support arm plate 402. Fig.11As shown, the opening between the two lower clamping plates 502 and the upper clamping plate 506 is buckled on both sides of the cylindrical beam with a larger diameter, so that the antenna is clamped and fixed on the cylindrical beam with a larger diameter; when clamping a cylindrical beam with a smaller diameter, first rotate the two worm screws 404 at the same time, so that the two groups of lower clamping plates 502 are first symmetrically pressed and located at the lower end of the cylindrical beam with a smaller diameter, and then rotate the two adjusting screws 508 at the same time, and then the clamping shaft 507 slides in the long hole 509, and then the two groups of upper clamping plates 506 are relatively pressed. After the two groups of upper clamping plates 506 are relatively pressed, the upper clamping plate 506 will slide on the clamping shaft 507 and the cross bar 601 through the long hole 509, and then the cross plate 602 pulls the tension spring 603 until the two groups of upper clamping plates 506 clamp the top of the cylindrical beam with a smaller diameter, completing the clamping and fixing, thereby achieving the clamping and fixing of the antenna to adapt to cylindrical beams with different diameters;

[0053] Moreover, by adjusting the installation position of the triangular block 504 and the opening direction of the lower clamping plate 502 and the upper clamping plate 506, and rotating the worm 404 to drive the two arm plates 402 to rotate, adjusting the opening direction of the two sets of lower clamping plates 502 and the upper clamping plates 506, and rotating the adjusting screw 508 to adjust the rotation of the upper clamping plate 506, the two clamping frames can be adapted to the clamping of beams with irregular shapes;

[0054] Among them, when the cross section of the beam column is a regular polygon with a regular pentagon or more, it can be directly regarded as a circular beam column for clamping and fixing;

[0055] When the cross section of the beam column is a square, when clamping, the angle between the lower clamping plate 502 and the upper clamping plate 506 can be adjusted to 90°, so that the openings between the two lower clamping plates 502 and the upper clamping plates 506 are buckled at the two opposite corners of the regular quadrilateral beam column, or the upper end surface of the regular quadrilateral beam column can be attached to the lower end surface of the mounting seat 201, and then the lower clamping plates 502 on both sides are pressed against the two sides of the regular quadrilateral beam column, and the upper clamping plates 506 on both sides are pressed against the lower end surface to clamp and fix;

[0056] When the cross section of the beam column is a quadrilateral, the corresponding lower clamping plate 502 and upper clamping plate 506 can be appropriately adjusted in the above manner to ensure that the quadrilateral beam column is clamped and fixed;

[0057] When the cross section of the beam column is a triangle, the upper end surface can also be attached to the lower end surface of the mounting seat 201 to perform the above-mentioned fixation, or the opening between the two lower clamping plates 502 and the upper clamping plate 506 can be made to correspond to the two sharp corners of the triangle, and then the two openings are buckled on the two sharp corners to complete the clamping fixation;

[0058] When the cross section of the beam column is an I-shaped beam, and the middle plate is flat, the base 102 can be directly placed on the middle plate. When the middle plate is hollowed out, the base 102 can be placed on the middle plate. Fig.13 In the manner shown, two sets of arm plates 402 are first inserted into the I-shaped frame, and then two worm gears 404 are rotated to drive the two sets of arm plates 402 to rotate outward, and then press against the two side walls of the I-shaped frame to complete the outward pressing clamping fixation;

[0059] It can be seen from the above embodiments that the two clamping frames of the antenna of the present application can adapt to the clamping effect of beams with irregular shapes.

[0060] Further:

[0061] By extending a control panel on the control frame 503 in a direction away from the middle seat 501 , the frame 503 can be more conveniently controlled to slide on the middle seat 501 through the control panel.

[0062] like Figure 4-7 As shown:

[0063] The middle part of the upper end of the mounting seat 201 is provided with a mounting groove 202 , and the middle part of the mounting seat 201 on both sides of the mounting groove 202 is provided with a slide groove 203 , and a clamping block 301 slides in the two slide grooves 203 , and both ends of the base 102 are provided with a clamping groove 103 .

[0064] First, the base 102 is installed in the installation slot 202 , and then the sliding block 301 is slid into the slot 103 , so as to limit the base 102 , thereby forming a firm fixation between the base 102 and the installation seat 201 .

[0065] Further:

[0066] A shifting plate 302 is fixed on each of the two clamping blocks 301 . The two shifting plates 302 are respectively limitedly slid on the two ends of the mounting seat 201 , and a spring II 303 is provided between the two shifting plates 302 and the mounting seat 201 .

[0067] The elastic force of spring II 303 can push the dial plate 302 and then drive the card block 301 to slide into the card slot 103, thereby ensuring that the card block 301 is always located in the card slot 103, thereby ensuring a firm installation and fixing state between the base 102 and the mounting seat 201, and preventing the card block 301 from automatically sliding out of the card slot 103, causing the base 102 and the mounting seat 201 to separate.

[0068] Further:

[0069] A chamfer I is provided at the upper end of the clamping block 301 , and a chamfer II 104 is provided at the lower end of the middle seat 501 .

[0070] When installing the base 102 into the installation groove 202, the base 102 can be aligned with the installation groove 202, and the base 102 can be pressed down. The chamfer I on the block 301 can be squeezed by the chamfer II 104, so that the two blocks 301 can squeeze the spring II 303, so that the block 301 slides into the slide groove 203, so that the base 102 can automatically slide into the installation groove 202, and after the base 102 completely slides into the installation groove 202, the two blocks 301 can automatically slide into the slot 103, completing the automatic installation and locking of the base 102, thereby improving the installation speed of the base 102.

[0071] Further:

[0072] A recessed groove 204 is provided at the center of the bottom of the installation groove 202 , a spring III 205 is provided in the recessed groove 204 , and a top plate 206 is provided at the upper end of the spring III 205 .

[0073] After the base 102 is installed in the installation groove 202, the base 102 will squeeze the spring III 205 through the top plate 206. When the base 102 needs to be removed from the mounting seat 201, the plate 302 is pushed outward at the same time to make the two blocks 301 slide out of the slot 103. The compressed spring III 205 will push the base 102 to quickly slide out of the installation groove 202 through the top plate 206, completing the rapid disassembly of the base 102 and the mounting seat 201; moreover, when the installation is completed, the spring III 205 presses the base 102 upward through the top plate 206, and cooperates with the two blocks 301 to limit the base 102, so that the installation of the base 102 and the mounting seat 201 is more stable.

[0074] Further:

[0075] By providing an anti-skid layer at the lower end of the base 102, when the base 102 is used to place objects directly, the anti-skid layer can ensure the stability of the base 102 and protect the surface of the placed object, thereby preventing the base 102 from damaging the surface of the placed object.
