[0035] The folding mechanism 7 includes bearings 71 fixedly connected to both sides of the connecting head 3 and the mounting seat 1. The outer sides of the two sets of bearings 71 are both rotatably sleeved with connecting plates 72. The surfaces of the two connecting plates 72 are provided with slide grooves 73 used in conjunction with the bearings 71, and the slide grooves 73 are arranged on the side of the connecting plate 72 close to the connecting head 3. A round pin 74 is fixedly connected to one side of the connecting head 3. A guide groove 75 used in conjunction with the round pin 74 is provided on one side of the inner wall of the protective cover 5, and the guide groove 75 consists of an arc groove and a vertical groove.

[0036] The sealing mechanism 8 includes an arc-shaped plate 81 movably sleeved on the outside of the connector 3, and a guide plate 82 used in conjunction with the arc-shaped plate 81 is symmetrically fixedly connected to the inside of the protective cover 5;

[0037] A square frame 83 is fixedly connected to one end of the top of the protective cover 5, and the cross-sectional shape of the square frame 83 is a sideways U-shape. The square frame 83 and the protective cover 5 are designed as an integral body. A T-shaped rod 84 is fixedly connected to the top of the inner wall of the square frame 83. The outer movably sleeve of the T-shaped rod 84 is connected to a limiting tube 85. A first spring 86 is arranged inside the limiting tube 85. One end of the top of the first spring 86 is fixedly connected to the bottom end of the T-shaped rod 84. Two limiting holes 87 used in conjunction with the limiting tube 85 are provided on the surface of the arc plate 81, and one of the limiting holes 87 is arranged on the side away from the connector 3, and the other limiting hole 87 is arranged on the side close to the connector 3.

The outer part of the limiting tube 85 is symmetrically fixedly connected with a protruding rod 89 used in conjunction with the dial plate 88, and the two protruding rods 89 are arranged above the dial plate 88.

[0038] The cross-sectional shape of the protective cover 5 is circular, the bearings 71 on both sides of the mounting seat 1 are arranged at the center of the protective cover 5, and the mounting seat 1 is provided with an anti-slip knob on the outside, and the anti-slip knob and the mounting seat 1 are designed as an integrated whole;

[0039] Before using the antenna 2, it is necessary to first connect the mounting base 1 to the intercom through the threaded connector at one end of the bottom of the mounting base 1. When the intercom antenna 2 needs to be unfolded, it is only necessary to press the paddle downward so that the paddle drives the outer portion of the T-shaped rod 84 of the limiting tube 85 to move upward through the two protruding rods 89 and squeeze the second spring 100 so that the limiting tube 85 moves out of one of the limiting holes 87 on the surface of the arc plate 81, thereby releasing the limiting effect of the limiting tube 85 on the arc plate 81. At this time, the connecting head 3 can be directly rotated so that the connecting head 3 is guided by the two connecting plates 72 and rotates along the through groove with the bearing 71 on the mounting base 1 as the center of the circle, so that the connecting head 3 pushes the arc plate 81 to slide synchronously between the two guide plates 82. In this process, the round pin 74 connected to the guide groove 75 is synchronously driven. When the connecting head 3 is rotated to the other side of the through groove, the connecting head 3 is in a vertical state, and the convex plate at one end of the top of the connecting head 3 corresponds to the groove at one end of the top of the mounting seat 1. At this time, the paddle can be loosened first to release the lifting effect of the paddle on the two convex rods 89, so that the limiting tube 85 drives the two convex rods 89 to move downward under the resetting effect of the second spring 100, so that the limiting tube 85 is inserted into another limiting hole 87 on the surface of the arc plate 81, thereby fixing the position of the arc plate 81 again, and then the connecting head 3 can be pushed downward, so that the connecting head 3 slides down inside the arc plate 81, so that the connecting head 3 drives the round pin 74 to move downward in the vertical groove in the guide groove 75 synchronously, so that the convex plate at one end of the top of the connecting head 3 is inserted into the groove at one end of the top of the mounting seat 1, and the antenna 2 can be unfolded and fixed.

[0040] When the antenna 2 needs to be folded, the connector 3 can be moved upward first, so that the connector 3 drives the round pin 74 to move upward inside the guide groove 75 synchronously, so that the connector 3 is moved out of the groove at the top of the mounting seat 1, and then the paddle is pressed again, so that the paddle releases the limiting fixing effect of the limiting tube 85 on the arc plate 81 through the cooperation between the above structures, and then the connector 3 is rotated in the opposite direction, so that the connector 3 rotates along the through groove to a position parallel to the mounting seat 1, so that the connector 3 drives the round pin 74 to slide inside the guide groove 75, and at the same time, the connector 3 drives the arc plate 81 to close the through groove, and then the paddle is released, so that the limiting tube 85 fixes the arc plate 81 under the cooperation between the above structures, and the folding of the antenna 2 and the sealing of the protective cover 5 can be completed;

[0041] The present invention is provided with a folding mechanism 7 and a sealing mechanism 8, which can not only realize the folding of the antenna 2, reduce the overall volume of the walkie-talkie, and improve the portability of the walkie-talkie, but also can protect the connection between the antenna 2 and the mounting base 1 and the wiring 4 when the antenna 2 is folded, so as to avoid the wiring 4 and the connection being exposed to the outside and being damaged by bumps or water ingress, so that the folding antenna 2 can be applied to various harsh environments, and the service life of the folding antenna 2 can be effectively extended, and the application range of the folding antenna 2 is increased.

[0042] like Figure 1-Figure 9 As shown, the interior of the mounting seat 1 is provided with a wire-retracting and -releasing mechanism 9 used in conjunction with the folding mechanism 7;

[0043] The wire-reeling and reeling mechanism 9 comprises a wire-reeling groove 91 provided inside the mounting seat 1, a wire-reeling roller 92 being rotatably connected inside the wire-reeling groove 91, a wire-threading groove 93 being provided inside the wire-reeling roller 92, and a side section of the wire-threading groove 93 being in an L-shape, the wire 4 passing through the wire-threading groove 93, a gear 94 being rotatably connected to the side of the mounting seat 1 away from the guide groove 75, a plurality of teeth 95 meshing with the gear 94 being evenly fixedly connected to the outer side of one end of one connecting plate 72 close to the mounting group, a group of pulleys 96 being used in coordination with each other being fixedly connected to one end of the gear 94 axle away from the mounting seat 1 and one end of the wire-reeling roller 92;

[0044] A square rod 97 is slidably connected to the side of the mounting seat 1 away from the guide groove 75, and the square rod 97 is arranged between the gear 94 and the take-up roller 92. One end of the square rod 97 extends to the inside of the take-up groove 91 and is fixedly connected to a collar 98, and the collar 98 is movably sleeved on the outside of the wiring 4. One end of the square rod 97 away from the collar 98 extends to the outside of the mounting seat 1 and is fixedly connected to an L-shaped plate 99. A second spring 100 is fixedly connected to the side of the L-shaped plate 99 close to the mounting seat 1, and the second spring 100 is movably sleeved on the outside of the square rod 97. A round rod 101 is fixedly connected to the bottom end of the L-shaped plate 99. A sleeve 102 is fixedly sleeved on the outside of the take-up roller 92, and a groove 103 used in conjunction with the round rod 101 is provided on the surface of the sleeve 102.

[0045] The outside of the take-up roller 92 is fixedly connected with a protrusion 104, and the protrusion 104 is arranged on one side of the threading groove 93 in the take-up direction;

[0046] The circumference of the pulley 96 at the end of the take-up roller 92 is one fifth of the circumference of the pulley 96 at the end of the axle of the gear 94, and the top view and bottom view of the groove 103 are both V-shaped;

[0047] In the process of opening the antenna 2, the connector 3 drives the two connecting plates 72 to rotate clockwise synchronously with the bearings 71 on both sides of the mounting seat 1 as the center. At this time, one of the connecting plates 72 drives the gear 94 to rotate counterclockwise through the meshing action between the multiple teeth 95 on the outer side and the gear 94, so that the gear 94 drives a group of pulleys 96 to rotate counterclockwise synchronously, so that a group of pulleys 96 drives the take-up roller 92 to rotate counterclockwise synchronously, and the wiring 4 is wound around the outside of the take-up roller, so that the exposed wiring 4 is collected into the take-up groove 91 when the antenna 2 is unfolded;

[0048] In the above-mentioned process of winding, the convex plate outside the winding roller 92 can be used as a pad to prevent the wiring 4 from being directly wound outside the winding roller 92, thereby preventing the bending part of the wiring 4 from being damaged due to too small an angle.

[0049] When the antenna 2 is folded, the connector 3 drives one of the connecting plates 72 to rotate counterclockwise under the cooperation between the above structures. At this time, the wiring board 4 drives a group of pulleys 96 to rotate clockwise through the meshing action between the multiple teeth 95 on the outside and the gear 94, so that the group of pulleys 96 drives the wire-receiving roller 92 to rotate clockwise synchronously, so that when the antenna 2 is folded, the distance between the connector 3 and the mounting seat 1 is coordinated, and the wiring 4 stored in the wire-receiving groove 91 is unfolded;

[0050] When the wire 4 is wound on the outside of the take-up roller 92, the take-up roller 92 drives the sleeve 102 to rotate synchronously. When the sleeve 102 rotates, the groove 103 on its surface drives the round rod 101 to move back and forth, so that the round rod 101 pushes the L-shaped plate 99 to move synchronously. When the L-shaped plate 99 moves toward the mounting seat 1, the second spring 100 is squeezed, and the ring 98 is pushed to move synchronously inside the take-up groove 91 through the square rod 97. When the L-shaped plate 99 moves away from the mounting seat 1, the sleeve 102 moves synchronously under the driving action of the second spring 100 and the L-shaped plate 99, so that the ring 98 drives the wire 4 to move back and forth inside the take-up groove 91, so that when the take-up roller 92 winds up the wire 4, the uniformity of the winding of the wire 4 is improved, thereby improving the utilization rate of the volume of the take-up groove 91 when the volume of the take-up groove 91 is limited.

[0051] The present invention is provided with a wire retracting and releasing mechanism 9, which can evenly reel the exposed wiring 4 into the mounting base 1 when the antenna 2 is unfolded, thereby preventing the antenna 2 from being exposed and getting stuck at the connection between the connector 3 and the mounting base 1, affecting the unfolding and use of the antenna 2. When the antenna 2 is folded, the folding mechanism 7 can cooperate to release the reeled wiring 4 to avoid pulling the wiring 4 when the antenna 2 is folded, thereby effectively improving the stability of the use of the folding antenna 2 and improving the overall practicality of the folding antenna 2.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
