Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to an antenna rotating shaft. Background Art

[0002] An antenna is a converter, a component used to transmit or receive electromagnetic waves in radio equipment. It converts guided waves propagating on the transmission line into electromagnetic waves propagating in an unbounded medium, or performs the opposite conversion. The antenna's transmission and reception are usually in a fan-shaped range. In order to facilitate better signal transmission, some antennas will be equipped with an antenna shaft to facilitate the adjustment of the antenna's direction, such as common router antennas, radio antennas, etc.

[0003] The existing antenna shaft generally achieves the effect of infinitely adjustable angle through friction or damping. After being adjusted a certain number of times, the antenna shaft with friction limit will lose its limiting effect due to increased gap due to wear, causing the antenna to become loose easily or even droop toward the ground due to gravity, affecting the normal signal reception and transmission of the antenna. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an antenna shaft to solve the technical problem that the antenna shaft that is infinitely adjusted by friction is prone to wear.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an antenna shaft, comprising a joint and a first shaft, wherein one side of the first shaft is connected to an elastic frame, and the inside of the elastic frame is connected to a spring sheet, the outer surface and the back of the elastic frame are connected to bosses, and friction rings are fixed to the outside of the two bosses.

[0006] By adopting the above technical solution, the angle of the bracket is limited by the friction between the friction ring and the bracket to prevent the bracket from loosening and sagging. When adjustment is required, the elastic frame and the spring sheet are bent by pressing the boss, so that the friction ring is separated from the bracket. Since the friction ring and the boss are both truncated cone-shaped, the inner end has a large diameter and the outer end has a small diameter, so that the boss and the friction ring can be displaced and retracted into the bracket after the elastic frame and the spring sheet are bent and deformed, and the gap between the boss and the friction ring and the bracket is increased. At this time, the friction between the friction ring and the bracket is small, which can reduce the wear between the structures and facilitate the rotation of the bracket to adjust the direction of the antenna body. After that, the elastic frame and the spring sheet are restored to their original state by releasing the hand through their own tension, so that the friction ring is again against the bracket and limited by friction.

[0007] Furthermore, the spring piece is in a herringbone shape and is made of spring steel.

[0008] By adopting the above technical solution and arranging the spring sheet made of spring steel, it is convenient to apply force to the two elastic frames to open the two frames, thereby assisting the structure to reset.

[0009] Furthermore, the spring pieces are provided in plurality and are symmetrically distributed.

[0010] By adopting the above technical solution and increasing the number of spring sheets, the elastic frame can be better driven to restore its shape so that the friction plate and the bracket are abutted against each other for limiting.

[0011] Furthermore, the elastic frame is made of POM material.

[0012] By adopting the above technical solution, the user presses down the boss hard to bend the elastic frame and the spring sheet, thereby separating the friction ring from the bracket. After the adjustment is completed, the user lets go to allow the elastic frame and the spring sheet to return to their original state through their own tension, so that the friction ring and the bracket are offset.

[0013] Furthermore, the boss and the friction ring are both truncated cone-shaped, and the two bosses and the friction rings are mirror-imaged.

[0014] By adopting the above technical solution, since the friction ring and the boss are both truncated cone-shaped, the inner end has a larger diameter and the outer end has a smaller diameter, so that the boss and the friction ring can be displaced and retracted into the bracket and increase the gap between them and the bracket after the elastic frame and the spring sheet are bent and deformed.

[0015] Furthermore, the first rotating shaft is connected to one side of the joint, a bracket is connected to one side of the outer surface of the elastic frame, and a cable is connected between the first rotating shaft and the bracket, and an antenna body is installed on the top of the bracket.

[0016] By adopting the above technical solution, the user installs the first rotating shaft on a radio device such as a router or a radio through a connector. At this time, the signal can be sent and received through the antenna body, and the direction of the antenna body can be adjusted along the X-axis through the first rotating shaft.

[0017] Furthermore, the bracket is rotatably connected to the elastic bracket, and the friction ring abuts against the bracket.

[0018] By adopting the above technical solution, the user moves the bracket to adjust its angle. After the adjustment, the friction ring and the bracket are abutted. The angle of the bracket is limited by the friction force between the friction ring and the bracket, thereby preventing the bracket from loosening and sagging.

[0019] Furthermore, fixing rings are fixed to the outside of the first rotating shaft and the bracket, and a sheath is fixed between the two fixing rings. The outer surface and back of the sheath are both provided with markings.

[0020] By adopting the above technical solution, the two ends of the sheath are respectively fixed to the first rotating shaft and the bracket through a fixing ring, so that the sheath always covers the connecting area between the two and the structure in the connecting area, avoiding negative effects of water, dust, moisture and other factors on the cable and the rotating structure.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model sets an elastic frame, a boss, a spring sheet and a friction ring, and limits the angle of the bracket by the friction force between the friction ring and the bracket, so as to avoid the bracket from loosening and sagging. When adjustment is needed, the boss is pressed to bend the elastic frame and the spring sheet, so that the friction ring is separated from the bracket. Since the friction ring and the boss are both in a truncated cone shape, the inner end has a large diameter, while the outer end has a small diameter, so that the boss and the friction ring can be displaced and retracted into the bracket after the elastic frame and the spring sheet are bent and deformed, and the gap between the boss and the friction ring and the bracket is increased. At this time, the friction force between the friction ring and the bracket is small, which can reduce the wear between the structures and facilitate the rotation of the bracket to adjust the direction of the antenna body. After that, the elastic frame and the spring sheet are restored to their original state by releasing the hand through their own tension, so that the friction ring is again against the bracket to be limited by friction, effectively reducing wear and extending the service life of the structure.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1:

[0031] An antenna shaft, such as Figure 2-Figure 4 As shown, it includes a joint 1 and a first rotating shaft 2, one side of the first rotating shaft 2 is connected to an elastic frame 8, the elastic frame 8 is made of POM material, a spring sheet 10 is connected inside the elastic frame 8, and the boss 9 is pressed to make the elastic frame 8 and the spring sheet 10 bend under force, so that the friction ring 11 is separated from the bracket 3; the spring sheet 10 is in a herringbone shape, and is made of spring steel material. There are multiple spring sheets 10, and the multiple spring sheets 10 are symmetrically distributed. The elastic frame 8 and the spring sheets 10 restore their original state through their own tension, so that the friction ring 11 and the bracket 3 are against each other; the outer surface and the back of the elastic frame 8 are connected to bosses 9, and friction rings 11 are fixed outside the two bosses 9. The bosses 9 and the friction rings 11 are both truncated cone-shaped, and the two bosses 9 and the friction rings 11 are mirror-set. The angle of the bracket 3 is limited by the friction force between the friction ring 11 and the bracket 3 to prevent the bracket 3 from loosening and sagging.

[0032] See also Figure 1-Figure 3 In the above embodiment, the first rotating shaft 2 is connected to one side of the joint 1, so that the antenna body 4 can be adjusted along the X-axis; a bracket 3 is connected to one side of the outer surface of the elastic frame 8, the bracket 3 is rotatably connected to the elastic frame 8, and the friction ring 11 abuts against the bracket 3 to adjust the direction of the antenna body 4 along the Z-axis; a cable 5 is connected between the first rotating shaft 2 and the bracket 3, and the antenna body 4 is installed on the top of the bracket 3 to facilitate sending and receiving signals.

[0033] Embodiment 2:

[0034] On the basis of the above-mentioned embodiment 1, although the elastic frame 8, the boss 9, the spring piece 10 and the friction ring 11 are provided to effectively reduce wear and thus extend the service life of the structure; however, factors such as water, dust and moisture have a negative impact on the cable 5 and the rotating structure; now, by providing the sheath 7, the connection area between the two and the structure in the connection area can be shielded to avoid the negative impact of factors such as water, dust and moisture on the cable 5 and the rotating structure. The connection area between the two and the structure in the connection area can be shielded to avoid the negative impact of factors such as water, dust and moisture on the cable 5 and the rotating structure.

[0035] See also Figure 1 and Figure 2In the above embodiment, a fixing ring 6 is fixed to the outside of the first rotating shaft 2 and the bracket 3, and a sheath 7 is fixed between the two fixing rings 6. The sheath 7 is made of silicone rubber material to shield the connection area between the two and the structure in the connection area to prevent water, dust, moisture and other factors from having a negative impact on the cable 5 and the rotating structure; the outer surface and back of the sheath 7 are provided with a mark 12, and the mark 12 is used to facilitate the user to determine the area where the boss 9 is located. The user only needs to put two fingers on the two marks 12 respectively to feel the boss 9.

[0036] The implementation principle of the utility model is as follows: first, the user installs the first rotating shaft 2 on a radio device such as a router or a radio through the connector 1, and adjusts the direction of the antenna body 4 along the X-axis through the first rotating shaft 2, that is, the center of the connector 1, and at the same time, fixes the two ends of the sheath 7 on the first rotating shaft 2 and the bracket 3 respectively through the fixing ring 6, so that the sheath 7 always shields the connection area between the two and the structure in the connection area, so as to prevent water, dust, moisture and other factors from having a negative impact on the cable 5 and the rotating structure;

[0037] When the user needs to adjust the direction of the antenna body 4 along the Z axis, that is, the center of the boss 9, the mark 12 is used to facilitate the user to determine the area where the boss 9 is located. The user only needs to put two fingers on the two marks 12 respectively to feel the boss 9. At this time, the user presses the boss 9 hard to bend the elastic frame 8 and the spring 10, so that the friction ring 11 is separated from the bracket 3. Since the friction ring 11 and the boss 9 are both truncated cones, the inner end has a large diameter, and the outer end has a small diameter, so that the boss 9 and the friction ring 11 can be separated after the elastic frame 8 and the spring 10 are bent and deformed. The friction ring 11 and the bracket 3 are small at this time. Firstly, the wear between the structures can be reduced. Secondly, it is convenient to rotate the bracket 3 to adjust the direction of the antenna body 4. At this time, the user can use the other hand to move the antenna body 4 to adjust its direction. After the adjustment, the user lets go so that the elastic frame 8 and the spring sheet 10 return to their original state through their own tension, so that the friction ring 11 and the bracket 3 are against each other. The angle of the bracket 3 is limited by the friction between the friction ring 11 and the bracket 3 to avoid the bracket 3 from loosening and sagging.
