Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0041] Please refer to Figures 1 to 4 , an anti-displacement structure in an embodiment of the present utility model includes a housing 1, an antenna 2, a limiting member 3 and a pressing member 4. A mounting wall 11 is formed on the housing 1, and the antenna 2 is passed through the mounting wall 11. The limiting member 3 is arranged on the housing 1, and the limiting member 3 circumferentially limits the antenna 2. The pressing member 4 is detachably arranged on the housing 1, and the mounting wall 11 and the pressing member 4 cooperate to axially limit the antenna 2.

[0042] In this embodiment, the limiting member 3 is used to circumferentially limit the antenna 2, effectively preventing the antenna 2 from rotating circumferentially. At the same time, the pressing member 4 and the mounting wall 11 cooperate to axially limit the antenna, effectively preventing the antenna 2 from moving axially in a straight line. The cooperation of circumferential limitation and axial limitation can effectively prevent the antenna 2 from being displaced under external forces, improve the overall installation stability and reliability, extend the service life of the device applying this anti-displacement structure, and effectively cope with the problem of relatively uncontrollable external force influence in the outdoor environment.

[0043] There are various ways for the limiting member 3 to circumferentially limit the antenna 2, as long as the antenna 2 is prevented from rotating circumferentially.

[0044] Optionally, for ease of assembly and disassembly, the limiting member 3 may be detachably mounted on the housing 1. For example, a structure with a limiting function or a clamping function is provided on the housing 1, and the limiting member 3 is detachably assembled on the housing 1.

[0045] In some alternative embodiments, such as Figure 1 and Figure 2 shown, a circumferential limiting groove 32 is formed in the limiting member 3, and the circumferential limiting groove 32 is a non-circular groove. The antenna 2 radially protrudes to form a first bulging portion 22, and the shape of the first bulging portion 22 is adapted to the shape of the circumferential limiting groove 32. The groove wall of the circumferential limiting groove 32 restricts the circumferential rotation of the first bulging portion 22.

[0046] Since the circumferential limiting groove 32 of the limiting member 3 is a non-circular groove, when the antenna 2 has a tendency of circumferential rotation, the side wall of the first bulging portion 22 will press against the groove wall of the circumferential limiting groove 32, and the groove wall of the circumferential limiting groove 32 prevents the antenna 2 from rotating, thereby realizing the circumferential limiting function. Moreover, the structure is simple and the assembly is convenient, which can effectively prevent the antenna 2 from rotating under the action of external force and prevent the cable from being bent and twisted.

[0047] As an example, the first bulging portion 22 may be a multi-prism, such as Figure 2 shown as a hexagonal prism in. The circumferential limiting groove 32 is adapted to the outer shape of the grooved multi-prism, and the side wall of the prism groove prevents the first bulging portion 22 from rotating, thereby preventing the antenna 2 from rotating. By adopting the multi-prism solution, the area where the groove wall of the circumferential limiting groove 32 abuts against the first bulging portion 22 can be increased to ensure the limiting effect.

[0048] Optionally, in order to facilitate the assembler to snap the first bulging portion 22 into the limiting member 3, the circumferential limiting groove 32 of the limiting member 3 is a notch groove, that is, part of the groove wall of the circumferential limiting groove 32 is missing, and reference can be made to Figure 1 . The shape of the notch groove can facilitate assembly or disassembly. During installation, first install the limiting member 3 on the housing 1, insert the antenna 2 into the installation wall 11, and then snap the first bulging portion 22 into the circumferential limiting groove 32 from the notch of the limiting member 3.

[0049] Optionally, as Figure 1 shown, in order to facilitate assembly, both ends of the notch of the limiting member 3 are provided with inclined guiding end faces 33. From the notch towards the inside of the circumferential limiting groove 32, the two guiding end faces 33 gradually incline towards each other to expand the area for the first bulging portion 22 to enter the notch, increase the tolerance, facilitate the assembler to assemble, and there is no need for precise alignment, so that the first bulging portion 22 can be smoothly snapped in during assembly.

[0050] Optionally, as Figure 1 shown, when the first bulging portion 22 is a hexagonal prism, two parallel edges of the circumferential limiting groove 32 are perpendicular to the notch for ease of assembly.

[0051] In some alternative embodiments, please refer to Figures 2 to 4 , one end of the pressing member 4 is a pressing portion 41, and the pressing portion 41 presses against the first bulging portion 22 towards the mounting wall 11 to axially position the first bulging portion 22, and the first bulging portion 22 is located between the pressing portion 41 and the mounting wall 11. In this way, the axial positioning of the antenna 2 can be achieved, preventing the antenna 2 from moving linearly in the axial direction and realizing the anti-disengagement function.

[0052] As an example, please refer to Figures 2 to 4 , the first bulging portion 22 can be a prism. One side of the first bulging portion 22 close to the mounting wall 11 is the first end face 221, and the side away from the mounting wall 11 is the second end face 222. The pressing portion 41 of the pressing member 4 presses against the second end face 222 to press the first bulging portion 22 between the mounting wall 11 and the pressing portion 41.

[0053] In some alternative embodiments, the first end face 221 of the first bulging portion 22 can press against the mounting wall 11. Optionally, in order to improve the sealing and waterproof effect, a sealing structure can be provided between the first end face 221 and the mounting wall 11.

[0054] For example, as shown in Figure 2 , a mounting through hole 111 is formed on the mounting wall 11, and one end of the antenna 2 is inserted into the mounting through hole 111. The first bulging portion 22 cannot pass through the mounting through hole 111. A sealing ring 6 is sleeved on the antenna 2, and the sealing ring 6 is located between the first bulging portion 22 and the mounting wall 11. The sealing ring 6 is used to seal the gap between the antenna 2 and the hole wall of the mounting through hole 111.

[0055] For the convenience of assembly and disassembly, the pressing member 4 is detachably arranged on the housing 1. As a reference solution, a structure with a limiting function or a clamping function can be provided on the housing 1; as another reference solution, additional parts can be provided on the pressing member 4 to detachably connect the pressing member 4 to the housing 1.

[0056] For example, please refer to Figure 1 and Figure 2 , the anti-disengagement structure further includes a locking member 5. The housing 1 forms a locking structure 15, and the locking member 5 is detachably connected to the locking structure 15. A positioning portion 42 is formed on the pressing member 4, and the locking member 5 positions the positioning portion 42 on the locking structure 15.

[0057] Optionally, the connection between the locking member 5 and the locking structure 15 is a threaded connection. For example, the locking member 5 is a screw, and the locking structure 15 includes a threaded groove column 151. The thread of the threaded groove column 151 is an internal thread. After the pressing member 4 is assembled, the locking member 5 can be screwed together with the positioning portion 42 onto the threaded groove column 151.

[0058] Alternatively, the locking member 5 can be a bolt, and the locking structure 15 can be a socket adapted to the bolt.

[0059] In some alternative embodiments, in order to increase the strength of the threaded groove column 151 and prevent the threaded groove column 151 from breaking, the locking structure 15 further includes a plurality of reinforcing ribs 152. The accommodating cavity 12 protrudes to form the reinforcing ribs 152, and one end of the reinforcing rib 152 is connected to the locking structure 15. Optionally, the other end of the reinforcing rib 152 extends to be connected to the clamping structure 13.

[0060] Optionally, for the convenience of processing and simplifying the component structure, as Figure 1 shown in, the pressing member 4 can be a bent member. The two ends of the pressing member 4 are respectively a fixing portion 42 and a pressing portion 41. A first included angle is formed between the fixing portion 42 and the pressing portion 41, and the first included angle is one of an acute angle, a right angle, and an obtuse angle. The pressing member 4 can be in a sheet shape.

[0061] Exemplarily, a first included angle is formed between the fixing portion 42 and the pressing portion 41, and the first included angle is a right angle. The mounting wall 11, the limiting member 3, and the pressing portion 41 are arranged side by side, and the fixing portion 42 abuts against the top end faces of the clamping structure 13 and the locking structure 15. The pressing portion 41 can prevent the antenna 2 from being displaced in the z-axis ( Figure 4 ) direction.

[0062] In some alternative embodiments, a receiving cavity 12 is formed on the housing 1, and the antenna 2 is located in the receiving cavity 12. A clamping structure 13 is formed in the receiving cavity 12, and the clamping structure 13 divides the receiving cavity 12 into a first groove body 121. The limiting member 3, the first bulging portion 22, and the pressing portion 41 are all located in the first groove body 121.

[0063] The clamping structure 13 is in a wall shape, and the limiting member 3, the first bulging portion 22, the pressing portion 41, and the clamping structure 13 are arranged side by side in sequence and pressed in sequence.

[0064] For the convenience of assembly, a first avoidance groove 131 can be formed on the clamping structure, and the first avoidance groove 131 can allow the antenna 2 to axially pass through.

[0065] The clamping structure 13 is both a limiting end for axial limitation and can be a positioning end for the fixing portion 42 of the pressing member 4.

[0066] Optionally, the clamping structure 13 divides the receiving cavity 12 into a first groove body 121 and a second groove body 122. One end of the antenna 2 is an exposed section 21, and the exposed section 21 passes through the outside through the mounting through hole 111. The first bulging portion 22 is located in the first groove body 121, and the other end of the antenna 2 away from the exposed section 21 is located in the second groove body 122.

[0067] In some alternative embodiments, please refer to Figure 1 and Figure 4, to facilitate the installation of the limiting member 3 on the housing 1, a buckling portion 14 is formed in the accommodating cavity 12. A first buckling groove 31 is formed on the limiting member 3, and the buckling portion 14 is buckled into the first buckling groove 31. The buckling portion 14 positions the limiting member 3 on the housing 1 in the y-axis ( Figure 4 ) direction, preventing the limiting member 3 from moving relative to the housing 1 in the y-axis direction.

[0068] Optionally, a second buckling groove 44 is formed on the pressing portion 41, and the buckling portion 14 is buckled into the second buckling groove 44. In this way, the buckling portion 14 positions the pressing portion 41 on the housing 1 in the y-axis ( Figure 4 ) direction, preventing the pressing member 4 from moving relative to the housing 1 in the y-axis direction.

[0069] In some alternative embodiments, the antenna 2 radially protrudes to form a second bulging portion 23, the size of the second bulging portion 23 is smaller than that of the first bulging portion 22, and the first bulging portion 22 is located between the second bulging portion 23 and the mounting wall 11.
