Description

Technical Field

[0001] This application relates to the field of antennas, and more particularly to a disassembly and installation device. Background Technology

[0002] Traditional antenna component installation primarily uses fasteners (bolts, screws, etc.), which is cumbersome, time-consuming, and inconvenient. For example, the antenna adapter, as a key connection component in a wireless communication system, functions to achieve efficient signal transmission between the antenna and the device or to provide power to the antenna through a mechanical interface. In existing technologies, the connection between the adapter and the antenna generally uses a plug-in structure, where the physical fixation and electrical conduction are achieved through the insertion and mating of the plug and pins. However, this structure has significant drawbacks in practical applications: when the adapter and antenna are exposed to a dynamic environment for extended periods, if the antenna vibrates, the mechanical fit between the plug and pins can gradually loosen. Loosening of the plug and pins can cause poor contact at the connection point between the adapter and the antenna, and in severe cases, can lead to separation and the antenna malfunctioning. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a disassembly and installation device.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides:

[0006] A disassembly and installation device, comprising:

[0007] A connector, which is fixedly connected to the antenna, has a receiving space;

[0008] A limiting member, wherein the limiting member is disposed in the accommodating space, and the limiting member has a limiting portion;

[0009] A linear drive unit is located on one side of the limiting member and is connected to the limiting member in a transmission manner. The linear drive unit is used to drive the limiting member to move in the accommodating space.

[0010] A connecting plate, located on one side of the connecting seat;

[0011] A snap-fit ​​component is fixedly disposed on the side of the connecting plate facing the connecting seat. The snap-fit ​​component passes through the outer wall of the connecting seat to the receiving space. The snap-fit ​​component has a limiting surface, and the limiting part abuts against the limiting surface.

[0012] Furthermore, the connecting seat includes a seat body and a cover, the seat body and the cover are fixedly connected, the seat body and the cover define the receiving space, the snap-fit ​​member is located in the receiving space, and the seat body is provided with a plug.

[0013] Furthermore, the base body is provided with a plurality of first clearance holes, and the snap-fit ​​part is located in the first clearance holes.

[0014] Furthermore, the cover is provided with a second clearance hole adapted to the plug and a third clearance hole corresponding to the snap-fit ​​component.

[0015] Furthermore, the limiting member has a relief groove, and the limiting part includes a first abutting part and a second abutting part disposed on the inner wall of the relief groove. The first abutting part and the second abutting part abut against the corresponding limiting surface on one side away from the connecting plate.

[0016] Furthermore, the connecting plate is provided with a fourth clearance hole adapted to the plug.

[0017] Furthermore, the snap-fit ​​component includes a connecting post, one end of which is integrally formed with a snap-fit ​​post, the snap-fit ​​post having the limiting surface, and both the connecting post and the snap-fit ​​post having through holes at their center positions.

[0018] Furthermore, the diameter of the connecting post is D1, and the diameter of the snap-fit ​​post is D2, satisfying that D2 > D1, and the connecting post and the snap-fit ​​post transition to form the limiting surface.

[0019] Furthermore, the snap-fit ​​component is detachably connected to the connecting plate via a connecting assembly. The connecting plate has multiple connecting holes. The connecting assembly includes a threaded post that passes through the through hole and through the connecting hole. One end of the threaded post is provided with an abutment, and the end of the threaded post away from the abutment is provided with a fastener.

[0020] Furthermore, the end face of the snap-fit ​​post away from the connecting post is provided with a receiving hole, the receiving hole is connected to the through hole, and the abutment is located in the receiving hole.

[0021] This application uses a linear drive to drive the limiting part of the limiting component to form a rigid abutment with the limiting surface of the snap-fit ​​component. The accommodating space of the connector constrains the movement trajectory of the limiting component, so that the snap-fit ​​component forms a bidirectional mechanical lock after passing through the outer wall of the connector. The rigid connection between the connecting plate and the adapter achieves vibration resistance and anti-detachment, effectively solving the problem of short circuits and connection detachment caused by friction failure in traditional plug-in structures under dynamic environments. The active locking mechanism driven by the linear drive makes the limiting part and the limiting surface form a surface contact pressure self-locking. Combined with the constraint of the hole wall of the snap-fit ​​component by the connector, it significantly improves the connection reliability of the antenna adapter in the case of antenna shaking.

[0042] This application provides a disassembly and installation device, specifically, the disassembly and installation device includes a connecting base 100, a limiting member 200, a linear drive member 300, a connecting plate 400, and a snap-fit ​​member 500.

[0043] In one embodiment, the connector 100 is fixedly connected to the antenna, the connector 100 has a receiving space, the limiting member 200 is disposed in the receiving space, the limiting member 200 has a limiting portion 210, the linear drive member 300 is located on one side of the limiting member 200, the linear drive member 300 is pulsatorically connected to the limiting member 200, the linear drive member 300 is used to drive the limiting member 200 to move in the receiving space, the connecting plate 400 is located on one side of the connector 100, the connecting plate 400 is installed and connected to the adapter, the snap-fit ​​member 500 is fixedly disposed on the side of the connecting plate 400 facing the connector 100, the snap-fit ​​member 500 passes through the outer wall of the connector 100 to the receiving space, the snap-fit ​​member 500 has a limiting surface 501, and the limiting portion 210 abuts against the limiting surface 501.

[0044] See Figure 1 and Figure 2 As shown, in the initial state, the limiting member 200 is located in the receiving space of the connecting seat 100, and the linear drive member 300 is connected to the limiting member 200. The linear drive member 300 can drive the limiting part 210 on the limiting member 200 to move linearly in the receiving space. When the adapter needs to be installed, the snap-fit ​​member 500 installed on the connecting plate 400 is first inserted through the connecting seat 100 into the receiving space. After the snap-fit ​​member 500 reaches the predetermined position, the linear drive member 300 drives the limiting member 200 to move, so that the limiting part 210 abuts against the limiting surface 501 of the snap-fit ​​member 500, thereby limiting the position of the snap-fit ​​member 500 and preventing it from snapping. When component 500 moves, since the snap-fit ​​component 500 is fixedly connected to the connecting plate 400, the position of the connecting plate 400 will also be restricted when the snap-fit ​​component 500 is positioned, thus completing the installation of the adapter connected to the connecting plate 400. When it is necessary to release the limiting position of the connecting plate 400, it is only necessary to use the linear drive component 300 to drive the limiting component 200 to move in the opposite direction, thereby separating the limiting part 210 from the limiting surface 501. The limiting part 210 and the limiting surface 501 will no longer be in contact, the position of the connecting plate 400 will no longer be restricted, and the snap-fit ​​component 500 can be detached from the receiving space, thus completing the disassembly of the connecting plate 400 and the adapter connected to the connecting plate 400.

[0045] In this embodiment, the linear drive 300 can be a butterfly lock. The limiting member 200 is connected to the moving end of the butterfly lock. By rotating the screw end of the butterfly lock, the moving end drives the limiting member 200 to move linearly, thereby driving the limiting part 210 of the limiting member 200 to abut or separate from the limiting surface 501, thereby realizing the quick installation and disassembly of the adapter connected to the connecting plate 400. In practice, the linear drive 300 can also be other structures or components that can drive the limiting member 200 to move linearly. The specific type is not limited here.

[0046] In one embodiment, the antenna is a board antenna.

[0047] In some specific embodiments, the connecting seat 100 includes a seat body 110 and a cover 120. The seat body 110 and the cover 120 are fixedly connected, and the seat body 110 and the cover 120 define the receiving space. The snap-fit ​​member 500 is located in the receiving space, and the seat body 110 is provided with a plug connector 111.

[0048] Please continue reading. Figure 1 and Figure 2As shown, the base 110 is fixedly connected to the antenna body. To enable the antenna to connect with the adapter, a connector 111 for connecting with the antenna is provided on the base 110. It can be understood that the connecting plate 400 is fixedly connected to the adapter, which has a connector head that matches the connector 111. During the insertion of the snap-fit ​​member 500 into the receiving space, the connector head contacts the connector 111 to achieve a mating connection. Then, the connecting plate 400 is fixedly connected to the connecting seat 100 through the cooperation of the limiting member 200 and the snap-fit ​​member 500. That is, the limiting part 210 abuts against the limiting surface 501 to limit the connecting plate 400 and prevent it from separating from the connecting seat 100, thus fixing the connecting plate 400 and the adapter connected to it. Compared with the existing plug-in type, since the connecting plate 400 and the connecting seat 100 are fixedly formed as a whole, the adapter is less likely to separate due to vibration or other reasons.

[0049] In some specific embodiments, the base 110 is provided with a plurality of first clearance holes 101, and the snap-fit ​​member 500 is partially located within the first clearance holes 101.

[0050] Please see Figure 2 , Figure 7 , Figure 9 as well as Figure 10 As shown, since the bottom surface of the limiting member 200 contacts the upper surface of the base 110, in order for the limiting part 210 to abut against the limiting surface 501, the limiting surface 501 needs to be at least flush with the upper surface of the base 110. For this purpose, the number of first clearance holes 101 is the same as the position and number of the snap-fit ​​member 500 on the upper surface of the base 110. During installation, the snap-fit ​​member 500 is partially located in the first clearance hole 101, and the limiting surface 501 is located below the upper surface of the base 110. Therefore, the limiting part 210 can be moved to the position of the limiting surface 501 and abut against it by the linear drive member 300, thereby limiting the position of the snap-fit ​​member 500, which also limits the position of the connecting plate 400.

[0051] In some specific embodiments, the cover 120 is provided with a second clearance hole 121 adapted to the plug 111 and a third clearance hole 122 corresponding to the snap-fit ​​500.

[0052] The connecting plate 400 is provided with a fourth clearance hole 401 that is adapted to the plug 111.

[0053] See Figure 2 as well as Figure 3As shown, in order to enable the adapter connector to connect with the plug 111 and to allow the snap-fit ​​500 to extend into the receiving space, a second clearance hole 121 and a third clearance hole 122 are provided through the upper surface of the cover 120, and a fourth clearance hole 401 is provided on the connecting plate 400. It should be noted that the number and position of the second clearance hole 121 and the fourth clearance hole 401 correspond to the number and position of the plug 111, and the number and position of the third clearance hole 122 correspond to the number and position of the snap-fit ​​500. Furthermore, the number and position of the third clearance hole 122 correspond to the position and number of the first clearance hole 101 mentioned above. That is, the number and position of the first clearance hole 101, the third clearance hole 122, and the snap-fit ​​500 are all the same, so that the snap-fit ​​500 can pass through the third clearance hole 122 into the receiving space and partially extend into the first clearance hole 101.

[0054] Furthermore, by opening a second clearance hole 121 on the cover 120 and a fourth clearance hole 401 on the connecting plate 400, the traditional method can still be used to connect the adapter connector to the plug 111 on the base 110. That is, the adapter leads out a cable, the end of the cable is provided with a connector, and then the connector passes through the fourth clearance hole 401 and the second clearance hole 121 to connect with the plug 111. Thus, in practice, the specific connection method can be selected according to the different types of adapters, and no specific limitation is made here.

[0055] In some specific embodiments, the limiting member 200 has a relief groove 201, and the limiting part 210 includes a first abutting part 211 and a second abutting part 212 disposed on the inner wall of the relief groove 201. The first abutting part 211 and the second abutting part 212 abut against the corresponding limiting surface 501 on a side away from the connecting plate 400.

[0056] See Figure 2 , Figure 4 , Figure 9 as well as Figure 10 As shown, in this embodiment, there are four snap-fit ​​pieces 500 arranged in a rectangular shape. The four snap-fit ​​pieces 500 are divided into two groups: two snap-fit ​​pieces 500 closer to the linear drive member 300 form one group, and the other two form another group. Since the positions of the two groups of snap-fit ​​pieces 500 are different, the limiting parts 210 are also different. Specifically, the limiting part 210 mainly includes a first abutting part 211 and a second abutting part 212. It should be noted that the first abutting part 211 is a protrusion located in the clearance groove 201, and the second abutting part 212 is located at the edge of the limiting member 200. A groove (not shown in the figure) for clearance is provided at the position of the second abutting part 212, so that the side wall of the clearance groove 201 avoids the connecting post 510 of the snap-fit ​​piece 500, preventing collision and motion interference.

[0057] In this embodiment, there are two first abutting portions 211 and two abutting portions 212. The bottom surface of the second abutting portion 212 abuts against the limiting surfaces 501 of the two latching members 500 in the direction close to the linear drive member 300. Correspondingly, the bottom surface of the frame of the limiting member 200 at the second abutting portion 212 abuts against the limiting surfaces 501 of the other two latching members 500, thereby achieving abutment and limiting of the limiting surfaces 501 of the four latching members 500, and thus limiting the position of the connecting plate 400 fixedly connected to the latching members 500.

[0058] In some specific embodiments, the snap-fit ​​component 500 includes a connecting post 510, one end of which is integrally formed with a snap-fit ​​post 520. The snap-fit ​​post 520 has the limiting surface 501. Both the connecting post 510 and the snap-fit ​​post 520 have through holes 530 at their center positions. The diameter of the connecting post 510 is D1, and the diameter of the snap-fit ​​post 520 is D2, satisfying that D2 > D1. The limiting surface 501 is formed by the transition between the connecting post 510 and the snap-fit ​​post 520.

[0059] See Figure 6 , Figure 8 , Figure 9 as well as Figure 10 As shown, in order for the limiting part 210 to abut against the limiting surface 501, the diameter of the snap-fit ​​post 520 is made larger than the diameter of the connecting post 510. Thus, the shape formed by the connecting post 510 and the snap-fit ​​post 520 is a stepped shaft, and the stepped surface of the stepped shaft is the limiting surface 501. That is, the connecting post 510 and the snap-fit ​​post 520 transition through the limiting surface 501.

[0060] In another embodiment, the diameters of the connecting post 510 and the snap-fit ​​post 520 can be the same, that is, the connecting post 510 and the snap-fit ​​post 520 form a cylinder with a through hole 530. An annular groove can be formed on the outer circumferential surface of the cylinder. The bottom surface of the annular groove is the limiting surface 501. The height of the annular groove can be adaptively selected according to the thickness of the limiting member 200. It can be understood that the part below the annular groove is the snap-fit ​​post 520, and the part above the annular groove is the connecting post 510.

[0061] In some specific embodiments, the snap-fit ​​member 500 is detachably connected to the connecting plate 400 via the connecting assembly 600. The connecting plate 400 has a plurality of connecting holes 402. The connecting assembly 600 includes a threaded post 610 that passes through the through hole 530 and through the connecting hole 402. One end of the threaded post 610 is provided with an abutment member 620, and the end of the threaded post 610 away from the abutment member 620 is provided with a fastener 630.

[0062] See Figure 5 and Figure 6 as well as Figure 11 As shown, this application uses a bolt connection to achieve the specified connection between the snap-fit ​​member 500 and the connecting plate 400. Specifically, the threaded post 610 and the abutment member 620 are integrally formed to form a bolt. In order to enable the bolt to have a connection point, a connection hole 402 corresponding to the position and number of snap-fit ​​members 500 is opened on the connecting plate 400. Next, the threaded post 610 passes through the through hole 530 and the connection hole 402 and extends to the side of the connecting plate 400 away from the cover member 120. At this time, the abutment member 620 abuts against the snap-fit ​​post 520. Then, the end of the threaded post 610 is screwed to install the fastener 630. As the fastener 630 is screwed, the stepped shaft with a central hole formed by the connecting post 510 and the snap-fit ​​post 520 is installed on the connecting plate 400, and the snap-fit ​​member 500 is located on the side of the connecting plate 400 facing the cover member 120.

[0063] In one embodiment, fastener 630 is a nut adapted to threaded post 610.

[0064] In another feasible embodiment, the inner wall of the through hole 530 can also be provided with internal threads. Then, the bolt is passed through the connecting hole 402 into the through hole 530. The external thread of the bolt is connected with the internal thread of the through hole 530. As the bolt continues to be tightened, the connection between the snap-fit ​​part 500 and the connecting plate 400 is realized. When using this method, it is not necessary to open the receiving hole 540 on the bottom surface of the snap-fit ​​post 520, and the through hole 530 does not need to be a through hole. It can also be a blind hole to achieve the connection, thereby improving the processing efficiency of the snap-fit ​​part 500 and reducing the processing difficulty.

[0065] In some specific embodiments, the end face of the snap-fit ​​post 520 away from the connecting post 510 is provided with a receiving hole 540, the receiving hole 540 is connected to the through hole 530, and the abutment 620 is located in the receiving hole 540.

[0066] Please continue reading. Figure 9 and Figure 10 as well as Figure 11 As shown, in order to prevent the abutment 620 from contacting the bottom wall of the first clearance hole 101 and causing the first clearance hole 101 to be opened deeper, a receiving hole 540 adapted to the abutment 620 is opened on the bottom surface of the snap-fit ​​post 520, and the receiving hole 540 is connected to the through hole 530.

[0067] It is understandable that the opening of the receiving hole 540 is only to reduce the depth of the first clearance hole 101. If the depth of the first clearance hole 101 meets the requirements, the receiving hole 540 does not need to be opened to accommodate the abutment 620. In practice, it can be selectively opened according to the actual situation.
