Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of antenna, especially to an antenna structure with adjusting and locking functions. BACKGROUND

[0002] With the development of smart phones, the number of antennas required by the mobile phone is increasing. At the same time, due to the increasing integration of mobile phones, the design of full-screen and multiple cameras makes the survival environment of mobile phone antennas worse and worse. A large number of occupied antenna use space makes the available area of the antenna less and less.

[0003] Antenna miniaturization has always been the goal pursued by the industry. In the current environment, most of the methods to reduce the size of the antenna are to modify the environment of the antenna and the material of the antenna body to reduce the frequency of the antenna. The disadvantage of standardizing the antenna is that the antenna cannot be debugged after being shaped. In order to make up for the multi-frequency requirement of the antenna, the size of the antenna is made larger.

[0004] The existing patent (announcement number: CN113471671B) is an antenna structure with adjustable electric length and communication equipment. In the case of connecting one end of the matching component to the first matching line or the second matching end of the basic line, the position of the first matching line or the second matching end of the basic line is adjusted, thereby modifying the electric length of the basic line. Under the premise of miniaturization of the board size, by setting the basic line and at least one matching line, an antenna structure with multiple electric lengths can be formed, thereby meeting different frequency requirements.

[0005] In view of the above problems, the existing patent provides a solution, but when the other end of the second matching line is connected to the basic end through the matching component, the position of the second matching end of the basic line changes, that is, the electric length between the second matching end and the basic end is modified. Its position is modified by modifying the length of the second matching end. When modifying the length, different lengths of basic lines need to be connected, which leads to adaptive interleaving, and on-site connection increases the operation steps, and connection point faults are also likely to occur, affecting the performance of the antenna. SUMMARY

[0006] The utility model aims at providing an antenna structure with adjusting and locking functions, which can solve the problem of connecting different lengths of basic lines when modifying the length, leading to adaptive interleaving, increasing the operation steps of on-site connection, and easily causing connection point faults, affecting the performance of the antenna.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an antenna structure with adjusting and locking functions, comprising an antenna main body, a first matching line is fixedly connected to the antenna main body, and a locking mechanism is arranged in the middle of the first matching line.

[0008] The locking mechanism comprises an adjusting plate arranged on one side of the first matching line, a moving groove is formed in the inside of the adjusting plate close to one side of the first matching line, a moving block is slidably connected in the inside of the moving groove, a first fixing rod is rotatably connected to one side of the moving block close to the first matching line, a transmission plate is fixedly installed on the top surface of the moving block, a pulling spring is fixedly installed on the top surface of the moving block, and a second fixing rod is arranged on one side of the first fixing rod.

[0009] Preferably, the adjusting plate is provided with two adjusting plates, and the two adjusting plates are arranged on both sides of the first matching line.

[0010] Preferably, the first fixing rod and the second fixing rod are arranged on both sides of the adjusting plate, and the structures of the two ends of the first fixing rod and the second fixing rod are the same.

[0011] Preferably, one end of the transmission plate penetrates through the top of the adjusting plate and extends into the inside of the adjusting plate, and the outer surface of the transmission plate is slidably connected with the adjusting plate, and one end of the transmission plate is located outside the adjusting plate.

[0012] Preferably, one end of the pulling spring is fixedly connected with the inner surface of the top of the moving groove.

[0013] Preferably, the middle part of the first matching line is S-shaped, and the locking mechanism is arranged at the bending part of the first matching line.

[0014] Preferably, gear grooves are formed around one end of the moving block inside the first fixing rod, and a stable block is fixedly installed on the bottom of the moving groove.

Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0027] Please refer to Figures 1 to 5 , the present application provides a technical solution:

[0028] An antenna structure with adjusting and locking functions, comprising an antenna main body 1, a first matching line 2 is fixedly connected to the antenna main body 1, and a locking mechanism 3 is arranged at the middle part of the first matching line 2.

[0029] The locking mechanism 3 comprises an adjusting plate 31 arranged on one side of the first matching line 2, the adjusting plate 31 is internally provided with a moving groove 32 near one side of the first matching line 2, the moving groove 32 is internally and slidably connected with a moving block 33, the moving block 33 is rotatably connected with a first fixed rod 34 on one side close to the first matching line 2, the top surface of the moving block 33 is fixedly connected with a transmission plate 35, and the top surface of the moving block 33 is fixedly connected with a pulling spring 36, and one side of the first fixed rod 34 is provided with a second fixed rod 37.

[0030] The fixing of the adjusting plate 31 is achieved by clamping the adjusting plate 31 by the cover plates on both sides after the antenna is connected, or a groove matched with the transmission plate 35 is arranged on the cover plate, so that one end of the transmission plate 35 is located in the groove.

[0031] The adjusting plate 31 is provided with two adjusting plates 31, and the two adjusting plates 31 are located on both sides of the first matching line 2, and the structures connected on the two adjusting plates 31 are the same.

[0032] The two adjusting plates 31 can limit the first fixed rod 34 from both sides of the first fixed rod 34.

[0033] The first fixed rod 34 and the second fixed rod 37 are located on both sides of the adjusting plate 31, and the structures of the first fixed rod 34 and the second fixed rod 37 at both ends are the same.

[0034] One end of the transmission plate 35 penetrates through the top of the adjusting plate 31 and extends to the inside of the adjusting plate 31, and the outer surface of the transmission plate 35 is slidably connected with the adjusting plate 31, and one end of the transmission plate 35 is located outside the adjusting plate 31.

[0035] One end of the pulling spring 36 is fixedly connected with the inner surface of the top of the moving groove 32.

[0036] The middle part of the first matching line 2 is S-shaped, and the locking mechanism 3 is located at the bending part of the first matching line 2.

[0037] By bending the first matching line 2, the length of the first matching line 2 can be reduced.

[0038] The first fixed rod 34 is provided with a gear groove 4 around one end in the moving block 33, and the bottom of the moving groove 32 is fixedly connected with a stable block 5.

[0039] The gear groove 4 is provided with a plurality of gear grooves 4, and the plurality of gear grooves 4 are equidistantly distributed, and the stable block 5 is triangular.

[0040] When the mobile block 33 moves downward, the first fixed rod 34 is driven to move downward, and the first fixed rod 34 moving downward makes one end of the stable block 5 enter the inside of the gear groove 4, thereby limiting the first fixed rod 34 from rotating, and improving the stability of positioning the first matching line 2.

[0041] Working principle:

[0042] When it is needed to lock the first matching line 2 after moving, the adjusting plate 31 is vertically placed, and after being placed, the transmission plate 35 at both ends of the adjusting plate 31 is extruded by the cover plates on both sides, so that the transmission plate 35 is extruded to move to the inside of the adjusting plate 31, the transmission plate 35 moving drives the mobile block 33 to move, the mobile block 33 moving drives the first fixed rod 34 and the second fixed rod 37 to move close to each other, thereby making the first fixed rod 34 and the second fixed rod 37 clamp the bent part of the first matching line 2, so that the position of one end of the first matching line 2 can be fixed, when it is needed to adjust the position of one end of the first matching line 2, the fixing of the cover plates on both sides of the adjusting plate 31 is released, so that the cover plates no longer extrude the transmission plate 35, and then the mobile block 33 is pulled by the pulling spring 36, so that the mobile block 33 drives the first fixed rod 34 and the second fixed rod 37 to move away from each other, thereby the first matching line 2 can be moved, so that the position of the first matching line 2 is adjusted.

[0043] Beneficial effects:

[0044] Through the locking mechanism 3, when the cover plate is not placed, the position of the first matching line 2 can be changed by moving the first matching line 2, and the electrical length between the first matching line and the base end is modified, so that it can adapt to more frequency requirements, and after adjustment, the transmission plate 35 is extruded by the cover plate, so that the transmission plate 35 drives the first fixed rod 34 and the second fixed rod 37 to move close to each other, so that the first fixed rod 34 and the second fixed rod 37 clamp the first matching line 2, so that the positioning of the first matching line 2 after adjustment is completed, avoiding the existing connection of different lengths of the first matching line 2, which not only increases the operation steps, but also the connection point is prone to failure, which affects the performance of the antenna main body 1.

[0045] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
