Description

Technical Field

[0001] The utility model relates to the field of antennas, in particular to a wifi antenna structure which is convenient for disassembly, assembly and maintenance. Background Art

[0002] Antenna is an indispensable item in daily life. It is a converter that converts guided waves propagating on the transmission line into electromagnetic waves propagating in unbounded media, or performs the opposite conversion. It is a component used to transmit or receive electromagnetic waves in radio equipment and is often used in router devices.

[0003] Most routers are composed of a supporting body, an antenna housing and an antenna. There are multiple sets of antennas inside the body, and the antennas are extended to the outside of the body. At the same time, the outside of the antenna is equipped with an antenna housing matching the number of antennas for protection. At the same time, the body is connected to various local area networks and wide area networks in the Internet. It will automatically select and set the route according to the channel conditions, send signals in the best path and in a forward and backward order, and transmit and receive radio waves carrying data through the antenna.

[0004] Most existing routers are equipped with multiple sets of antennas. However, most of these antennas are connected by clips or bolts. When an antenna fails and needs to be repaired inside, workers need to remove the antenna casing. In addition, since the antenna casing is mostly fixed by a simple clip structure composed of grooves and blocks, in order to ensure its stability, the connection between the block and the groove is relatively tight, which makes it more laborious to remove. The clip will be deformed due to multiple disassembly, resulting in a reduced engagement amount and a reduced connection effect, resulting in a limited number of disassembly times for most clips. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a wifi antenna structure that is easy to disassemble, assemble and repair, so as to solve the technical problem.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wifi antenna structure that is easy to disassemble and repair includes a fixed bracket, an antenna housing and an antenna, a fixed block is fixedly installed at one end of the fixed bracket, and sliding shafts are symmetrically installed on both sides of the fixed block, a second sliding groove for the sliding shaft to slide is provided inside the antenna housing, a connecting rod is fixedly installed at one end of the sliding shaft, and a spring shaft is slidably connected inside the sliding shaft, a sliding block is fixedly installed at one end of the spring shaft, a first sliding groove for the sliding block to slide is provided inside the sliding shaft, a first spring connected to the spring shaft is sleeved on the outside of the connecting rod, and the other end of the first spring is connected to the fixed block, and a limiting hole for limiting the spring shaft is provided inside the antenna housing.

[0007] By adopting the above technical scheme, a sliding shaft, a spring shaft, a fixed block and a limiting hole are provided, and the angle of the antenna shell is controlled by the cooperation of the limiting hole and the sliding shaft. When disassembly is required, the spring shaft only needs to be pressed into the sliding shaft, and the antenna shell body is rotated to directly separate the antenna shell from the fixed bracket to complete the disassembly. Compared with the traditional snap-on structure, it is more convenient to disassemble, and workers can disassemble and repair it more quickly and conveniently, and the force required for disassembly will be reduced, which can better protect the antenna shell and the antenna inside it, reduce the probability of damage, and increase the disassembly speed of the antenna shell. By providing a push block, a limiting groove and a pull rod, the antenna can be automatically fixed when the antenna is adjusted to the optimal angle, preventing the user from accidentally touching the antenna during use, causing the overall angle of the antenna to change, affecting the signal transmission of the antenna.

[0008] The utility model is further configured that a limiting groove is provided on the side of the antenna housing, a reset rod is movably installed inside the fixed bracket, and a push block engaged with the limiting groove is fixedly installed at one end of the reset rod.

[0009] By adopting the above technical solution, the push block can enter the limiting groove after the antenna housing moves a certain distance, and the antenna housing is fixed by limiting the position with the limiting groove.

[0010] The utility model is further configured that a pull rod is fixedly mounted on the top surface of the push block and the end surface corners of the push block are designed as arc-shaped bevel angles.

[0011] By adopting the above technical solution, the pull rod allows the user to control the push block more conveniently. The end face corners of the push block are designed with arc-shaped bevels so that the push block will move toward the inside of the fixed bracket when under pressure, ensuring that it can smoothly enter the limit groove.

[0012] The utility model is further configured that the outer sleeve of the reset rod is provided with a second spring connected to the fixed bracket, and the other end of the second spring is connected to the push block.

[0013] By adopting the above technical solution, the second spring is connected to the push block and the fixed bracket, so that the reset rod applies a forward force to the push block, ensuring that the position will not shift when the antenna housing is fixed and limited, making the fixation more secure.

[0014] The utility model is further configured such that the diameter of the sliding shaft is greater than the diameter of the limiting hole and greater than the diameter of the spring shaft.

[0015] By adopting the above technical solution, since the diameter of the sliding shaft 3 is larger than the limiting hole 12, the sliding shaft 3 can only slide in the second sliding groove 11. At the same time, since the diameter of the spring shaft 10 is smaller than the diameter of the limiting hole 12, the spring shaft 10 can be smoothly popped out of the limiting hole 12, so that the antenna housing 4 can rotate around the spring shaft 10.

[0016] The utility model is further configured that a moving groove for the push block to move is provided inside the fixed bracket, and a third sliding groove for the pull rod to move is provided at the top of the fixed bracket.

[0017] By adopting the above technical solution and setting the movable groove, the push block 13 can slide smoothly in the fixed bracket 1, ensuring that the push block 13 can subsequently successfully complete the limiting fixation of the antenna housing 4. By setting the movable groove and the third sliding groove 9, the pull rod 14 can move the push block 13 in the hole of the movable groove inside the fixed bracket 1 within a certain range.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] The utility model is provided with a sliding shaft, a spring shaft, a fixing block and a limiting hole, etc., and the angle of the antenna shell is controlled by the setting of the limiting hole and the sliding shaft. When disassembly is required, the spring shaft only needs to be pressed into the sliding shaft, and the antenna shell body is rotated, so that the antenna shell can be directly separated from the fixing bracket to complete the disassembly. Compared with the traditional snap-on structure, the disassembly is more convenient, and the workers can disassemble and repair more quickly and conveniently. At the same time, the force required for disassembly will also be reduced, and the probability of damage when disassembling the antenna shell is reduced. By providing a push block, a limiting groove and a pull rod, the antenna can be automatically fixed when the antenna is adjusted to the optimal angle, thereby ensuring the fixity of the angle of the antenna when in use, and preventing the antenna from being accidentally touched by a kitten or other people during use, causing the antenna position to shift, thereby affecting the transmission of the antenna signal.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] A wifi antenna structure that is easy to disassemble and repair, such as Figure 1-6 As shown, it includes a fixed bracket 1, an antenna housing 4 and an antenna 18, a fixed block 2 is fixedly installed at one end of the fixed bracket 1, and sliding shafts 3 are symmetrically installed on both sides of the fixed block 2, the setting of the sliding shaft 3 allows the fixed block 2 to be connected to the antenna housing 4, a second sliding groove 11 for the sliding shaft 3 to slide is opened inside the antenna housing 4, so that the antenna housing 4 can rotate around the fixed block 2 through the second sliding groove 11, a connecting rod 5 is fixedly installed at one end of the sliding shaft 3, and a spring shaft 10 is slidably connected inside the sliding shaft 3, a slider 7 is fixedly installed through one end provided with the spring shaft 10, a first sliding groove 8 for the slider 7 to slide is opened inside the sliding shaft 3, a first spring 6 connected to the spring shaft 10 is sleeved on the outside of the connecting rod 5, and The other end of the first spring 6 is connected to the fixed block 2. At the same time, a limiting hole 12 for limiting the spring shaft 10 is opened inside the antenna housing 4. When the antenna housing 4 is rotated, the sliding shaft 3 rotates in the second sliding groove 11. The second sliding groove 11 applies pressure to the spring shaft 10. The cooperation between the first sliding groove 8 and the slider 7 allows the spring shaft 10 to enter the sliding shaft 3 when under pressure. After rotating a certain distance, since the limiting hole 12 is larger than the spring shaft 10, the spring shaft 10 loses pressure, and the first spring 6 inside it pops out the spring shaft 10. The spring shaft 10 can be limited and fixed through the limiting hole 12, so that the antenna housing 4 can rotate around the spring shaft 10 and freely adjust the angle within the limit, which is convenient for use.

[0030] See also Figure 5A limiting groove 17 is provided on the side of the antenna housing 4, and the limiting groove 17 can limit and fix the push block 13. A reset rod 15 is movably installed inside the fixed bracket 1, and one end of the reset rod 15 is fixedly installed with a push block 13 that is engaged with the limiting groove 17. The push block 13 can be squeezed by the antenna housing 4 after the antenna housing 4 moves a certain distance and first retreats into the fixed bracket 1, and then when passing through the limiting groove 17, it enters the limiting groove 17 under the elastic force of the second spring 16. The antenna housing 4 is fixed by the limiting of the push block 13 and the limiting groove 17, so that the angle of the antenna housing 4 is fixed during use, which reduces the deviation of the angle of the antenna housing 4 due to accidental touch or collision, which makes the signal transmission effect worse and affects the use.

[0031] See also Figure 5 A pull rod 14 is fixedly installed on the top surface of the push block 13, and the pull rod 14 allows the user to more conveniently operate the push block 13, and the end surface corners of the push block 13 are designed with arc-shaped bevels. The end surface corners of the push block 13 are designed with arc-shaped bevels, so that the push block 13 will move toward the inside of the fixed bracket 1 when squeezed by the antenna housing 4, ensuring that it can smoothly enter the limit groove 17.

[0032] See also Figure 6 The outer sleeve of the reset rod 15 is provided with a second spring 16 connected to the fixed bracket 1, and the other end of the second spring 16 is connected to the push block 13. The second spring 16 is connected to the push block 13 and the fixed bracket 1, so that the second spring 16 applies a forward force to the push block 13, ensuring that when the antenna housing 4 is fixed and limited, the push block 13 and the limiting groove 17 are not misaligned, resulting in the inability to complete the limit or offset, making the fixed limit more reliable.

[0033] See also Figure 3 The diameter of the sliding shaft 3 is greater than the diameter of the limiting hole 12 and greater than the diameter of the spring shaft 10. Since the diameter of the sliding shaft 3 is greater than the limiting hole 12, the sliding shaft 3 can only slide in the second sliding groove 11. Meanwhile, since the diameter of the spring shaft 10 is smaller than the diameter of the limiting hole 12, the spring shaft 10 can be smoothly ejected from the limiting hole 12, so that the antenna housing 4 can rotate around the spring shaft 10.

[0034] See also Figure 6 A moving groove for the push block 13 to move is provided inside the fixed bracket 1. Through the setting of the moving groove, the push block 13 can slide smoothly inside the fixed bracket 1, ensuring that the push block 13 can subsequently successfully complete the limiting fixation of the antenna housing 4, and a third slide groove 9 for moving the pull rod 14 is provided at the top of the fixed bracket 1. By setting the moving groove and the third slide groove 9, the pull rod 14 can move within a certain range in the hole of the push block 13 in the moving groove inside the fixed bracket 1.

[0035] The working principle of the utility model is as follows: when it is necessary to disassemble the antenna housing 4, the pull rod 14 is pulled to make the push plate 13 move into the fixed bracket 1 to release the limit of the antenna housing 4, so that the spring shaft 10 can rotate around the limit hole 12, press the spring shaft 10 to make it enter the interior of the sliding shaft 3, rotate the antenna housing 4 to make the sliding shaft 3 move in the second slide groove 11, and after the antenna housing 4 rotates and moves to a certain distance, the antenna housing 4 is separated from the fixed block 2 to complete the disassembly. When it is necessary to install the antenna housing 4, the second slide groove 11 opened in the antenna housing 4 is aligned with the position of the spring shaft 10. When the spring shaft 10 enters the second slide groove 11, it is squeezed into the interior of the sliding shaft 3. After rotating to a certain distance, the spring shaft 10 pops out from the limit hole 12 to complete the fixation of the antenna housing 4. At the same time, when the antenna housing 4 is rotated to adjust it to reach the optimal working angle, the push plate 13 pops out and enters the limit groove 17 of the antenna housing 4 to complete the fixed limit of the antenna housing 4 and keep it at the optimal use angle.

[0036] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
