Description

TECHNICAL FIELD

[0001] The present application relates to the field of antennas, in particular to a fixing assembly, an antenna and a fixing member. BACKGROUND

[0002] The current reflecting plate and PCB board are prone to loosening or even falling off during use after being fixed by the support member, which affects the normal use of the equipment and increases the maintenance cost of the equipment. SUMMARY

[0003] In order to solve the above problems, the present application provides a fixing assembly, an antenna and a fixing member, which are ingenious in design and simple in structure. The first fixing member is tightly clamped with the plate-shaped structure through extrusion between the second fixing member and the first fixing member, which reduces the requirement for the machining precision of the preset through hole, weakens the influence of the cumulative tolerance of the assembly, and prevents loosening of the first fixing member. The technical solutions adopted by the present application are as follows:

[0004] A fixing assembly for fixing to a preset through hole of a plate-shaped structure, comprising:

[0005] A first fixing member comprising a body, a first clamping portion and a second clamping portion, wherein the body has a mounting hole extending in a first direction, and the first clamping portion and the second clamping portion are connected to the body;

[0006] A second fixing member mounted in the mounting hole;

[0007] Wherein, the first clamping portion and the second clamping portion are locally protruding relative to the body, and the first clamping portion and the second clamping portion are spaced apart along the first direction; the second clamping portion is adapted to pass through the preset through hole, so that the first clamping portion abuts against the plate-shaped structure;

[0008] The second fixing member is adapted to move in the mounting hole to push the first clamping portion and / or the second clamping portion outward to abut against the plate-shaped structure, and to clamp the plate-shaped structure by the first clamping portion and the second clamping portion.

[0009] The present application is ingenious in design and simple in structure. The first fixing member is tightly clamped with the plate-shaped structure through extrusion between the second fixing member and the first fixing member, which reduces the requirement for the machining precision of the preset through hole, weakens the influence of the cumulative tolerance of the assembly, and prevents loosening of the first fixing member.

[0010] In some embodiments, the second clamping portion is provided with a first inclined surface which gradually inclines away from the first clamping portion in a direction away from the axis of the mounting hole;

[0011] The second fastener is adapted to move within the mounting hole to push the second snap-fit ​​portion passing through the preset through hole outward, so that the first inclined surface abuts against the plate-like structure.

[0012] By setting the first inclined surface, when the second fastener pushes against the second snap-fit ​​part, the second snap-fit ​​part moves away from the axis of the mounting hole, so that the first inclined surface abuts against the edge of the preset through hole on the plate structure and squeezes the preset through hole, thereby making the plate structure tightly snapped between the first snap-fit ​​part and the second snap-fit ​​part.

[0013] In some embodiments, the portion of the second snap-fit ​​portion that protrudes relative to the portion of the body that is partially protruding includes a first protrusion portion that protrudes toward a direction close to the axis of the mounting hole;

[0014] The second fastener is adapted to move within the mounting hole to push the first protrusion of the second snap-fit ​​portion passing through the preset through hole outward, so that the second snap-fit ​​portion abuts against the plate-like structure.

[0015] By setting the first protrusion, when the second fastener moves along the depth direction of the mounting hole, it will cause the first protrusion to be squeezed away from the axis of the mounting hole, thereby driving the second snap-fit ​​part to expand the preset through hole on the plate structure, so that the plate structure is tightly snapped with the first fastener.

[0016] In some embodiments, the second snap-fit ​​portion, relative to the portion of the body that protrudes partially, includes a second protrusion that protrudes in a direction away from the axis of the mounting hole.

[0017] The second fastener is adapted to move within the mounting hole to push the second protrusion of the second snap-fit ​​portion passing through the preset through hole outward, so that the second snap-fit ​​portion abuts against the plate-like structure.

[0018] By providing a second protrusion, the maximum cross-sectional size of the second snap-fit ​​portion is increased, enabling the second snap-fit ​​portion to accommodate larger preset through-hole sizes and thicker plate structures, thereby increasing the size range of preset through-holes and the thickness range of plate structures that the first fastener can accommodate.

[0019] In some embodiments, the portion of the second snap-fit ​​portion that protrudes relative to the body portion includes a first protrusion portion and a second protrusion portion, wherein the first protrusion portion protrudes toward a direction close to the axis of the mounting hole, and the second protrusion portion protrudes toward a direction away from the axis of the mounting hole.

[0020] The second fastener is adapted to move within the mounting hole to push the first and second protrusions of the second snap-fit ​​portion passing through the preset through hole outward, so that the second snap-fit ​​portion abuts against the plate-like structure.

[0021] By simultaneously providing the first protrusion and the second protrusion, the plate structure can be easily and tightly engaged with the first fastener, and the maximum cross-sectional size of the second engaging part can be increased, allowing the second engaging part to accommodate larger preset through-hole sizes and thicker plate structures.

[0022] In some embodiments, the second protrusion is provided with a first guide surface, which gradually slopes away from the first snap-fit ​​portion along the direction close to the axis of the mounting hole.

[0023] By setting a first guide surface, during the process of inserting the first fastener into the preset through hole of the plate structure, the edge of the preset through hole will cause the first guide surface to be squeezed towards the axis of the mounting hole, causing the second protrusion to move towards the axis of the mounting hole, thereby allowing the second snap-fit ​​portion of the first fastener to gradually pass through the preset through hole. The setting of the first guide surface facilitates the insertion of the first fastener into the preset through hole.

[0024] In some embodiments, the first snap-fit ​​portion has a second inclined surface relative to the partially protruding portion of the body, and the second inclined surface gradually slopes away from the second snap-fit ​​portion along a direction away from the axis of the mounting hole.

[0025] The preset through hole may have a second chamfer. When the first snap-fit ​​part and the second snap-fit ​​part clamp the plate-shaped structure, the second inclined surface is in contact with the surface of the second chamfer.

[0026] By setting a second bevel, since the cross-sectional dimensions of the part of the first snap-fit ​​portion where the second bevel is set are continuously changing, the first snap-fit ​​portion can adapt to preset through holes of different sizes, thus increasing the adaptability range of the first snap-fit ​​portion; in addition, when the preset through hole is set with a second chamfer, the first snap-fit ​​portion can be connected to the plate structure by the fit between the second bevel and the second chamfer surface, without the first snap-fit ​​portion protruding from the plate surface of the plate structure.

[0027] In some embodiments, the first snap-fit ​​portion has a first plane relative to the partially protruding portion of the body, and when the first snap-fit ​​portion and the second snap-fit ​​portion clamp the plate-like structure, the first plane abuts against the plate-like structure.

[0028] By setting the first plane, the contact area between the first snap-fit ​​part and the plate structure can be increased, thus making the connection more secure.

[0029] In some embodiments, the inner wall of the mounting hole is provided with internal threads, and the second fastener is a bolt adapted to the internal threads.

[0030] In some embodiments, the inner wall of the mounting hole is provided with internal threads within a certain length range, and the bolt is provided with external threads within a certain length range.

[0031] By setting internal threads within a localized length of the mounting hole and external threads within a localized length of the bolt, the bolt can be installed into the mounting hole without needing to be fully tightened, thus shortening the bolt tightening stroke and improving bolt installation efficiency.

[0032] In some embodiments, the second fixing member is a rod, which, when moving within the mounting hole along the depth direction of the mounting hole, pushes the second locking portion away from the axis of the mounting hole.

[0033] On the other hand, this application provides an antenna including the aforementioned fixing components.

[0034] On the other hand, this application provides a fastener for fixing to a pre-defined through hole in a plate-like structure, comprising:

[0035] The body has mounting holes extending along a first direction;

[0036] The first latching part and the second latching part are both connected to the main body;

[0037] Wherein, both the first snap-fit ​​portion and the second snap-fit ​​portion are partially protruding relative to the body, and the first snap-fit ​​portion and the second snap-fit ​​portion are spaced apart along the first direction; the second snap-fit ​​portion is adapted to pass through the preset through hole, so that the first snap-fit ​​portion abuts against the plate-like structure;

[0038] The mounting hole is adapted to insert a bolt to push the first snap-fit ​​portion and / or the second snap-fit ​​portion outward against the plate-like structure, so that the first snap-fit ​​portion and the second snap-fit ​​portion clamp the plate-like structure.

[0039] The fixing component, antenna, and fixing element provided in this application have at least the following beneficial effects:

[0040] 1. The fixing component, antenna and fixing member provided in this application are ingeniously designed and have a simple structure. By squeezing the second fixing member and the first fixing member, the first fixing member is tightly engaged with the plate structure, which reduces the requirements for the machining accuracy of the preset through hole, weakens the influence of the cumulative tolerance of the component, and can prevent the first fixing member from loosening.

[0041] 2. The fixing component, antenna and fixing member provided in this application, by setting a first inclined surface, when the second fixing member abuts against the second locking part, the second locking part moves away from the axis of the mounting hole, so that the first inclined surface abuts against the edge of the preset through hole on the plate structure and squeezes the preset through hole, thereby making the plate structure tightly locked between the first locking part and the second locking part.

[0042] 3. The fixing component, antenna and fixing member provided in this application, by setting a first protrusion, causes the second fixing member to be squeezed in a direction away from the axis of the mounting hole when it moves along the depth direction of the mounting hole, thereby driving the second snap-fit ​​part to expand the preset through hole on the plate structure, so that the plate structure is tightly snapped with the first fixing member.

[0043] 4. The fixing component, antenna and fixing member provided in this application increases the maximum cross-sectional size of the second snap-fit ​​portion by setting the second protrusion, so that the second snap-fit ​​portion can adapt to a larger preset through hole size and a thicker plate structure, thereby increasing the size range of the preset through hole and the thickness range of the plate structure that the first fixing member can adapt to.

[0044] 5. The fixing component, antenna and fixing member provided in this application, by setting a first guide surface, when the first fixing member is inserted into the preset through hole of the plate structure, the edge of the preset through hole will squeeze the first guide surface in the direction close to the axis of the mounting hole, so that the second protrusion moves in the direction close to the axis of the mounting hole, thereby allowing the second snap-fit ​​part of the first fixing member to gradually pass through the preset through hole. The setting of the first guide surface facilitates the insertion of the first fixing member into the preset through hole.

[0045] 6. The fixing component, antenna and fixing member provided in this application, by setting a second inclined surface, can adapt to preset through holes of different sizes because the cross-sectional size of the part of the first snap-fit ​​portion where the second inclined surface is set is continuously changing, thereby increasing the adaptability range of the first snap-fit ​​portion; in addition, when a second chamfer is set in the preset through hole, the first snap-fit ​​portion can be abutted against the plate structure by the fit of the second inclined surface and the second chamfer surface, without the first snap-fit ​​portion protruding from the plate surface of the plate structure;

[0046] 7. The fixing component, antenna and fixing part provided in this application, by setting internal threads in a local length range of the inner wall of the mounting hole and external threads in a local length range of the bolt, can shorten the bolt tightening stroke and improve the bolt installation efficiency when the bolt is installed into the mounting hole without having to tighten the bolt for the entire length.

[0064] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0065] To enable the first fastener 1 to adapt to plate structures 3 with various preset through-hole sizes, reduce the requirements for the machining accuracy of the preset through-holes, mitigate the impact of cumulative tolerances in the components, and simplify the installation procedure of the first fastener 1, please refer to the accompanying drawings in the instruction manual. Figures 1 to 9 This application provides a fixing component for fixing to a pre-set through hole in a plate-like structure 3, comprising:

[0066] The first fastener 1 includes a body 11, a first snap-fit ​​portion 12, and a second snap-fit ​​portion 13; the body 11 has a mounting hole 111 extending in a first direction, and the first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 are both connected to the body 11.

[0067] The second fastener 2 is installed in the mounting hole 111;

[0068] The first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 are both partially protruding relative to the body 11, and the first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 are spaced apart along the first direction; the second snap-fit ​​portion 13 is adapted to pass through a preset through hole so that the first snap-fit ​​portion 12 abuts against the plate structure 3.

[0069] The second fastener 2 is adapted to move within the mounting hole 111 to push the first snap-fit ​​portion 12 and / or the second snap-fit ​​portion 13 outward against the plate-like structure 3, and to clamp the plate-like structure with the first snap-fit ​​portion 12 and the second snap-fit ​​portion 13.

[0070] In this embodiment, the plate-like structure can be a reflective plate or a PCB board. In other embodiments, the plate-like structure can also be other types of plates. In this embodiment, the first direction refers to the length direction of the first fixing member, and also the length direction of the mounting hole.

[0071] In this embodiment, a portion of the second locking part 13 can move within an elastic range. When the second locking part 13 deforms, an elastic restoring force is generated, which causes the second locking part 13 to tend to return to its original position. It is worth noting that when the first fixing member 1 passes through the preset through hole, and the preset through hole presses against the second locking part 13, causing the second locking part 13 to move, the first fixing member 1 can be locked onto the plate-like structure 3 through the cooperation of the first locking part 12 and the second locking part 13. In this case, there is no need for the second fixing member 2 to press against the second locking part 13. However, the pressing between the second fixing member 2 and the second locking part 13 makes the first fixing member 1 more tightly locked onto the plate-like structure 3. (Refer to the accompanying drawings for details.) Figures 2 to 8 To understand.

[0072] In this embodiment, the first snap-fit ​​part 12 is elastically connected to the body 11, or the second snap-fit ​​part 13 is elastically connected to the body 11, or both the first snap-fit ​​part 12 and the second snap-fit ​​part 13 are elastically connected to the body 11.

[0073] In this embodiment, the first fixing member 1 and the plate structure 3 can be gradually locked together by the second fixing member 2 gradually pushing against the first locking part 12, or the first fixing member 1 and the plate structure 3 can be gradually locked together by the second fixing member 2 gradually pushing against the second locking part 13, or the first fixing member 1 and the plate structure 3 can be gradually locked together by the second fixing member 2 pushing against both the first locking part 12 and the second locking part 13.

[0074] In such Figure 2In the embodiment shown, the second snap-fit ​​part 13 does not have a protrusion on the side away from the axis of the mounting hole 111, but has a protrusion on the side close to the axis of the mounting hole 111. When the second snap-fit ​​part 13 passes through the preset through hole, it must rely on mutual compression with the second fixing member 2 to move. In other words, the first fixing member 1 can only be snapped onto the plate structure 3 with the help of the second fixing member 2.

[0075] In such Figure 9 In the illustrated embodiment, with Figure 1 The difference between the embodiments shown is: Figure 9 The second locking portion 13 does not have a protrusion on the side near the axis of the mounting hole 111, but instead has a variable diameter section 23 (equivalent to a protrusion) on the second fixing member 2. As the second fixing member 2 gradually penetrates deeper into the mounting hole 111, the variable diameter section 23 gradually presses against the second locking portion 13, causing the second locking portion 13 to move away from the axis of the mounting hole 111. Figure 9 In the illustrated embodiment, the second fastener 2 is installed onto the first fastener 1 from the end near the first snap-fit ​​portion 12, while... Figure 1 In the illustrated embodiment, the second fastener 2 is mounted to the first fastener 1 from the end furthest from the first engaging portion 12. It is understood that whether a protrusion is provided on the first fastener 1, the second fastener 2, or both, the protrusion serves to allow the first fastener 1 and the second fastener 2 to press against each other during relative movement, causing the first fastener 1 to move or deform. When a protrusion that can press against the second fastener 2 is provided on the first fastener 1, the protrusion on the first fastener 1 can be provided on the second engaging portion 13, such as... Figures 1 to 5 , Figures 7 to 8 As shown; the protrusion can also be provided on the first latching portion 12, such as Figure 6 As shown; or protrusions may be provided on both the first latching portion 12 and the second latching portion 13, such as Figure 6 As shown.

[0076] In this embodiment, the compression between the second fixing member 2 and the first fixing member 1 makes the first fixing member 1 tightly engaged with the plate structure 3, which reduces the requirements for the machining accuracy of the preset through hole, weakens the influence of the cumulative tolerance of the component, and prevents the first fixing member 1 from loosening.

[0077] Refer to the attached diagram in the instruction manual. Figures 1 to 10 In one embodiment, the second snap-fit ​​portion 13 is provided with a first inclined surface 131, which gradually tilts away from the first snap-fit ​​portion 12 along the direction away from the axis of the mounting hole 111; the second fastener 2 is adapted to move within the mounting hole 111 to push the second snap-fit ​​portion 13 passing through the preset through hole outward, so that the first inclined surface 131 abuts against the plate structure 3.

[0078] In this embodiment, by providing a first inclined surface 131, when the second fixing member 2 pushes against the second locking part 13, the second locking part 13 moves away from the axis of the mounting hole 111, causing the first inclined surface 131 to abut against the edge of the preset through hole on the plate-like structure 3 and press against the preset through hole, thereby making the plate-like structure 3 tightly locked between the first locking part 12 and the second locking part 13. In this embodiment, the first inclined surface 131 is a plane; in other embodiments, it can also be a curved surface or an arc surface. For example, when the preset through hole is a round hole and the preset through hole has a chamfer, the first inclined surface 131 can be replaced by a part of a conical surface, so that when the second locking part 13 abuts against the plate-like structure 3, the conical surface and the chamfered surface are tightly attached.

[0079] Refer to the attached diagram in the instruction manual. Figures 1 to 10 In one embodiment, the portion of the second snap-fit ​​portion 13 that protrudes partially relative to the body 11 includes a first protrusion portion 132, which protrudes toward the axis of the mounting hole 111; the second fastener 2 is adapted to move within the mounting hole 111 to push the first protrusion portion 132 of the second snap-fit ​​portion 13 that passes through the preset through hole outward, so that the second snap-fit ​​portion 13 abuts against the plate structure 3.

[0080] In this embodiment, by providing the first protrusion 132, when the second fixing member 2 moves along the depth direction of the mounting hole 111, it will cause the first protrusion 132 to be squeezed away from the axis of the mounting hole 111, thereby driving the second snap-fit ​​part 13 to expand the preset through hole on the plate-like structure 3, so that the plate-like structure 3 is tightly snapped with the first fixing member 1. In other embodiments, the second snap-fit ​​part 13 may not have the first protrusion 132, but instead has a protrusion on the second fixing member 2. When the second fixing member 2 moves relative to the first fixing member 1, the protrusion on the second fixing member 2 and the second snap-fit ​​part 13 squeeze each other, driving the second snap-fit ​​part 13 to move or deform.

[0081] refer to Figure 1 , Figures 3 to 10 In one embodiment, the portion of the second snap-fit ​​portion 13 that protrudes partially relative to the body 11 includes a second protrusion portion 133, which protrudes in a direction away from the axis of the mounting hole 111; the second fastener 2 is adapted to move within the mounting hole 111 to push the second protrusion portion 133 of the second snap-fit ​​portion 13 that passes through the preset through hole outward, so that the second snap-fit ​​portion 13 abuts against the plate-like structure 3.

[0082] In this embodiment, by providing the second protrusion 133, the maximum cross-sectional size of the second snap-fit ​​portion 13 is increased, allowing the second snap-fit ​​portion 13 to accommodate larger preset through-hole sizes and thicker plate-like structures 3. This, in turn, increases the range of preset through-hole sizes and the range of plate-like structure 3 thicknesses that the first fastener 1 can accommodate. In other embodiments, refer to... Figure 2 The second snap-fit ​​portion 13 may also omit the second protrusion 133.

[0083] In one embodiment, a first protrusion 132 and a second protrusion 133 can be provided simultaneously. By providing the first protrusion 132 and the second protrusion 133 simultaneously, the plate structure can be easily and tightly engaged with the first fastener 1, and the maximum cross-sectional size of the second engaging part 13 can be increased, so that the second engaging part 13 can adapt to a larger preset through hole size and a thicker plate structure, resulting in better performance.

[0084] Reference Manual Figure 1 , Figures 3 to 10 In one embodiment, the second protrusion 133 is provided with a first guide surface 134, which gradually tilts away from the first snap-fit ​​portion 12 along the direction close to the axis of the mounting hole 111.

[0085] In this embodiment, by providing a first guide surface 134, during the process of inserting the first fixing member 1 into the preset through hole of the plate structure 3, the edge of the preset through hole will compress the first guide surface 134 towards the axis of the mounting hole 111, causing the second protrusion 133 to move towards the axis of the mounting hole 111. This allows the second snap-fit ​​portion 13 of the first fixing member 1 to gradually pass through the preset through hole. The provision of the first guide surface 134 facilitates the insertion of the first fixing member 1 into the preset through hole. In other embodiments, the second snap-fit ​​portion 13 may not have the first guide surface 134. The second protrusion 133 can be clamped by hand during the installation of the first fixing member 1, allowing the second snap-fit ​​portion 13 to pass through the preset through hole. Alternatively, a clamping member can be used to hold the second protrusion 133 of the second snap-fit ​​portion 13. After the second snap-fit ​​portion 13 passes through the preset through hole, the clamping member can be removed to release the second snap-fit ​​portion 13.

[0086] In such Figure 6In the illustrated embodiment, the first snap-fit ​​portion 12 is provided with a third protrusion 123. As the second fixing member 2 is inserted deeper into the mounting hole 111, the second fixing member 2 will press against the third protrusion 123, driving the first snap-fit ​​portion 12 to move away from the axis of the mounting hole 111, making the snap-fit ​​between the first fixing member 1 and the plate structure 3 tighter. A second guide surface 124 can also be provided on the first snap-fit ​​portion 12, so that the first fixing member 1 can be inserted into the preset through hole not only along the first guide surface 134, but also along the second guide surface 124, thus realizing bidirectional installation of the first fixing member 1.

[0087] Refer to the attached diagram in the instruction manual. Figures 1 to 3 , Figures 6 to 10 In one embodiment, the first snap-fit ​​portion 12 is provided with a second inclined surface 121 relative to the portion of the body 11 that is partially protruding. The second inclined surface 121 gradually slopes away from the second snap-fit ​​portion 13 along the direction away from the axis of the mounting hole 111.

[0088] In this embodiment, preferably, reference is made to the accompanying drawings. Figure 3 The pre-set through hole has a second chamfer (not shown in the figure). When the first snap-fit ​​part 12 and the second snap-fit ​​part 13 clamp the plate-shaped structure, the second inclined surface 121 is in contact with the surface of the second chamfer.

[0089] In this embodiment, by providing a second inclined surface 121, since the cross-sectional dimensions of the portion of the first snap-fit ​​part 12 where the second inclined surface 121 is provided are continuously changing, the first snap-fit ​​part 12 can adapt to preset through holes of different sizes, thus increasing the adaptability range of the first snap-fit ​​part 12. In addition, when a second chamfer is provided in the preset through hole, the first snap-fit ​​part 12 can be abutted against the plate structure 3 by the fit between the second inclined surface 121 and the second chamfer surface, without the first snap-fit ​​part 12 protruding from the plate surface of the plate structure 3.

[0090] Refer to the attached diagram in the instruction manual. Figure 4 , Figure 5 In one embodiment, the first snap-fit ​​portion 12, which protrudes partially from the body 11, has a first plane 122. When the first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 clamp the plate-like structure, the first plane 122 abuts against the plate-like structure 3. Figure 4 and Figure 5 In the illustrated embodiment, the first snap-fit ​​portion 12 can be fixedly connected to the body 11, while... Figure 6 In the illustrated embodiment, the first snap-fit ​​portion 12 can be elastically connected to the body 11, similar to the second snap-fit ​​portion 13. Additionally, Figure 4 and Figure 5 In the illustrated embodiment, both the first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 are located near one end of the body 11, so that after the first fastener 1 is installed, it will be as follows: Figure 3As shown, one end of the first fastener 1 is flush with one side of the plate-like structure 3. Figure 5 In the installation configuration shown, a countersunk hole can also be provided on one side of the plate-like structure 3, so that the first snap-fit ​​part 12 is located within the countersunk hole, similarly achieving an installation effect where one end of the first fastener 1 is flush with one side of the plate-like structure 3. However, the first snap-fit ​​part 12 and the second snap-fit ​​part 13 can also be located at any position along the length of the body 11, so that after installation, the body 11 of the first fastener 1 is located on both sides of the plate-like structure 3, which can be used in application scenarios where installation is required on both sides. The second snap-fit ​​part 13 can be connected to the body 11 on one side in a cantilever structure, or it can be connected to the body 11 on both sides along the length of the body 11.

[0091] In this embodiment, the first latching portion 12 is further away from the body 11 of the first fastener 1 than the second latching portion 13. In other embodiments, the first latching portion 12 may be closer to the body 11 of the first fastener 1 than the second latching portion 13. In other words, the first latching portion 12 and the second latching portion 13 may interchange positions, that is, the first plane 122 of the first latching portion 12 abuts against the side of the plate structure 3 closer to the body 11, while the protrusion of the second latching portion 13 abuts against the side of the plate structure 3 away from the body 11.

[0092] Refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 In one embodiment, the inner wall of the mounting hole 111 is provided with an internal thread 112, and the second fastener 2 is a bolt adapted to the internal thread 112.

[0093] It is understandable that the second fastener 2 and the first fastener 1 can be connected by other methods besides threaded connection, such as... Figure 8 The snap-fit ​​method shown in the figure. Figure 8 In the embodiment shown, the mounting hole 111 has a plurality of slots 113 on its wall, and the second fixing member 2 has a plurality of teeth 22. The connection between the second fixing member 2 and the first fixing member 1 is completed by the teeth 22 being engaged in the slots 113.

[0094] Refer to the attached diagram in the instruction manual. Figure 7 In one embodiment, an internal thread 112 is provided within a certain length of the inner wall of the mounting hole 111, and an external thread 21 is provided within a certain length of the bolt.

[0095] In this embodiment, by providing an internal thread 112 within a local length range of the inner wall of the mounting hole 111 and an external thread 21 within a local length range of the bolt, when the bolt is installed into the mounting hole 111, it is not necessary to fully tighten the bolt, which can shorten the bolt tightening stroke and improve the bolt installation efficiency.

[0096] In one embodiment, the second fixing member 2 is a rod. When the rod moves along the depth direction of the mounting hole 111 within the mounting hole 111, it pushes the second engaging portion 13 away from the axis of the mounting hole 111. In this embodiment, the rod's function is simply to push against the second engaging portion 13, driving it away from the axis of the mounting hole 111, so that the first fixing member 1 is fixed in the preset through hole of the plate structure 3. The rod can be a threaded bolt or a smooth rod; in short, as long as the rod can provide a tightening effect, it is acceptable.

[0097] Refer to the attached diagram in the instruction manual. Figure 10 In one embodiment, the preset through hole is a square hole, and the second snap-fit ​​portion 13 is adapted to abut against the square hole.

[0098] In this embodiment, the preset through hole is set as a square hole. When the second snap-fit ​​part 13 is adapted to the square hole, it can prevent the first fixing member 1 from rotating relative to the plate-like structure 3 in the preset through hole, further restricting the relative movement of the plate-like structure 3 and the first fixing member 1. In other embodiments, the preset through hole can also be a round hole, an elliptical hole, or other types of holes. It is understood that the hole wall of the preset through hole can be set as chamfered or beveled as needed.

[0099] In one embodiment, this application also provides a fastener for fixing to a pre-defined through hole in the plate-like structure 3, comprising:

[0100] The body 11 has a mounting hole 111 extending in a first direction;

[0101] The first latching part 12 and the second latching part 13 are both connected to the main body 11;

[0102] The first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 are both partially protruding relative to the body 11, and the first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 are spaced apart along the first direction; the second snap-fit ​​portion 13 is adapted to pass through a preset through hole so that the first snap-fit ​​portion 12 abuts against the plate structure 3.

[0103] Mounting hole 111 is adapted to pass through bolts to push the first snap-fit ​​portion 12 and / or the second snap-fit ​​portion 13 outward against the plate-like structure 3, so that the first snap-fit ​​portion 12 and the second snap-fit ​​portion 13 clamp the plate-like member.

[0104] In this embodiment, the features of the fastener are the same as those of the first fastener 1 described above, and will not be repeated here to save space.

[0105] In one embodiment, this application also provides an antenna including the aforementioned fixing component. For brevity, the features of the fixing component will not be described again here.

[0106] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
