Description

Technical Field

[0001] The utility model relates to the technical field of WiFi antennas, and in particular to a small WiFi antenna which is convenient for adjusting the antenna receiving direction. Background Art

[0002] A WiFi antenna is a device that is mainly used to enhance wireless network signals. It is divided into two types: internal and external. External WiFi antennas generally need to be installed on related equipment in some way. However, existing external WiFi antennas do not have a fixing plate and are generally directly inserted into the device in use. They are easily pulled out by external forces, affecting signal transmission.

[0003] A Chinese patent discloses a new type of WiFi antenna (authorization announcement number is CN215266634U). The WiFi antenna body can adjust the angle through an adjustment mechanism to adapt to more actual situations, reduce the situation where the signal is affected, and improve the stability of WiFi signal transmission.

[0004] Since the only device used to adjust the angle of the WiFi antenna in the above device is the rotating shaft, although this can quickly adjust the angle of the WiFi antenna, the above device is not provided with a structure that can lock the angle. When external forces such as gravity act on the WiFi antenna, the WiFi antenna can easily rotate and deviate under the influence of the external forces, causing the receiving direction of the WiFi antenna to change, thereby affecting the signal reception accuracy of the WiFi antenna.

[0005] Therefore, a small WiFi antenna which is convenient for adjusting the antenna receiving direction is proposed to solve the above problems. Utility Model Content

[0009] Preferably, a second arc groove in contact with the universal ball is formed at one end of the friction block, and the center point of the second arc groove coincides with the center point of the universal ball, which can increase the contact area between the friction block and the universal ball, and further increase the limiting effect on the position of the WiFi antenna body.

[0010] Preferably, a reserved groove is formed at the other end of the friction block, and one end of the rubber spring is fixedly connected to the reserved groove, which can reserve sufficient expansion and contraction space for the rubber spring and avoid the possibility of the rubber spring being damaged due to excessive pressure.

[0011] Preferably, the direction adjustment mechanism also includes two adjustment components, the adjustment component includes an adjustment block hinged to the outer surface of the n-shaped threaded seat, one end of the adjustment block is slidably connected to a slide rod, one end of the slide rod sequentially penetrates the n-shaped threaded seat, the installation cavity and the rubber spring and is fixedly connected to the reserved groove, when the staff needs to adjust the angle of the WiFi antenna body, the user only needs to squeeze the two adjustment blocks relative to each other, and the adjustment blocks can separate the friction block from the universal ball by pulling the slide rod. At this time, the WiFi antenna body loses its obstruction, and the user can easily adjust the angle of the WiFi antenna body, and after the adjustment is completed, the user only needs to loosen the adjustment block, and the rubber spring can reset the friction block by itself and fix the n-shaped threaded seat on the surface of the universal ball, without the need for manual adjustment by the user, thereby achieving the purpose of facilitating the user to adjust the receiving direction of the WiFi antenna body.

[0012] Preferably, the vertical cross-section of the adjusting block is V-shaped, which can increase the length of the adjusting block pulling the sliding rod outward, so as to ensure that the friction block can be effectively separated from the universal ball.

[0013] Preferably, a slide groove is provided at one end of the adjustment block, and the other end of the slide rod passes through the interior of the slide groove and is slidably connected to the slide groove, which can ensure that the slide rod can move normally horizontally following the rotation of the adjustment block, and further ensures that the friction block can be effectively separated from the universal ball.

[0014] Preferably, the horizontal cross-sections of the slide groove and the contact portion between the slide rod and the slide groove are both T-shaped, which can not only prevent the slide rod from sliding out of the slide groove, but also the slide groove can prevent the slide rod and the friction block from rotating to ensure the normal operation of the friction block.

[0015] The beneficial effects of the utility model are:

[0016] 1. When the WiFi antenna body moves in a specific direction, the rubber spring can press the friction block tightly against the surface of the universal ball, which can prevent the n-shaped threaded seat from driving the WiFi antenna body to rotate and deviate, making the WiFi antenna body run more stably;

[0017] 2. When the staff needs to adjust the angle of the WiFi antenna body, the user only needs to squeeze the two adjustment blocks relative to each other, and the adjustment blocks can separate the friction block from the universal ball by pulling the sliding rod.

At this time, the rubber spring can reset the friction block by itself and fix the n-shaped threaded seat on the surface of the universal ball. There is no need for the user to manually adjust it, thereby achieving the purpose of facilitating the user to adjust the receiving direction of the WiFi antenna body.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4 As shown, a small WiFi antenna that is easy to adjust the antenna receiving direction includes: a WiFi antenna body 1 and a USB interface 2, wherein the WiFi antenna body 1 is electrically connected to the top of the USB interface 2; and a direction adjustment mechanism 3, wherein the direction adjustment mechanism 3 is fixedly connected between the WiFi antenna body 1 and the USB interface 2.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the direction adjustment mechanism 3 includes a universal ball 31 and an n-shaped threaded seat 32, the universal ball 31 is fixedly connected to the top of the USB interface 2, the n-shaped threaded seat 32 is threadedly connected to the bottom of the WiFi antenna body 1, and the two opposite inner surfaces of the n-shaped threaded seat 32 are provided with a first arc groove 321 that is slidably connected to the universal ball 31, and the n-shaped threaded seat 32 is provided with two installation cavities 322 that are respectively connected to the two first arc grooves 321. A friction block 33 in contact with the universal ball 31 is slidably connected inside the mounting cavity 322, and a rubber spring 34 that is always in a compressed state is arranged between the friction block 33 and the mounting cavity 322; a second arc groove 331 in contact with the universal ball 31 is formed at one end of the friction block 33, and the center point of the second arc groove 331 coincides with the center point of the universal ball 31; a reserved groove 332 is formed at the other end of the friction block 33, and one end of the rubber spring 34 is fixedly connected to the reserved groove 332.

[0026] like Figure 3 and Figure 4As shown, the direction adjustment mechanism 3 also includes two adjustment components 35, and the adjustment components 35 include an adjustment block 351 hinged on the outer surface of the n-shaped threaded seat 32, one end of the adjustment block 351 is slidably connected to a slide rod 352, one end of the slide rod 352 passes through the n-shaped threaded seat 32, the mounting cavity 322 and the rubber spring 34 in sequence and is fixedly connected to the reserved groove 332; the vertical cross-sectional shape of the adjustment block 351 is V-shaped; a slide groove 3511 is provided at one end of the adjustment block 351, and the other end of the slide rod 352 passes through the interior of the slide groove 3511 and is slidably connected to the slide groove 3511; the horizontal cross-sectional shapes of the slide groove 3511 and the contact parts of the slide rod 352 and the slide groove 3511 are both T-shaped.
