Detailed Description of the Embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following provides a detailed description of the specific embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0026] It should be noted that the orientations or positional relationships indicated by various orientation terms are based on the orientations or positional relationships shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", etc. in the description and claims of the present utility model are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence; and, without conflict, the embodiments and features in the embodiments of the present utility model can be combined arbitrarily with each other.

[0027] Those of ordinary skill in the art should understand that the diagrams provided herein are for illustrative purposes only and are not necessarily drawn to scale. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or there can be intervening elements; connections can be classified into fixed connections, sliding connections, and rotational connections by type. In the case where it is not explicitly specified, the connection generally refers to a fixed connection, and the fixed connection can be a detachable connection or a non-detachable connection.

[0028] To solve the problems in the prior art that the connection and fixation of signal transmission devices through bolts increase the installation complexity and time consumption, and when the bolt connection is abnormal, it will cause the signal transmission device to tilt or even fall off, etc., the embodiments of the present utility model provide a quick-release mechanism applied to signal transmission devices in a 5G private network system, aiming to improve the problem that the signal transmission devices used in the 5G private network system cannot be quickly disassembled.

[0029] As Figures 1 to 3 shown, the quick-release mechanism includes: a push block 1, a clamping assembly, and a fixed block 10. The push block 1 and the clamping assembly can be referred to as the first disassembly assembly.

[0030] Among them, the top of the fixed block 10 is connected to the bottom of the signal transmission device 13 to play a role in fixedly connecting the signal transmission device 13. When the fixed block 10 is disassembled, it can be disassembled together with the signal transmission device 13. The clamping assembly includes a transmission part and two clamping arms connected thereto. The two clamping arms are respectively located on both sides of the fixed block 10; the transmission part is connected to the push block 1 and is used to drive the two clamping arms to open in opposite directions to release the fixed block 10 under the action of the thrust provided by the push block 1, and to drive the two clamping arms to close in opposite directions to clamp the fixed block 10 when the thrust provided by the push block 1 disappears.

[0031] In this embodiment, the quick disassembly of the signal transmission device is realized through a quick disassembly mechanism. Compared with the method of disassembling the signal transmission device by bolt connection in the prior art, the installation and disassembly are simpler and more convenient, and the installation is firm, which can prevent the signal transmission device from tilting or even falling off, thereby ensuring the normal operation of the 5G private network system and the stability of the network connection.

[0032] In a specific embodiment, as Figure 3 shown, grooves are provided on both sides of the fixed block 10 (i.e., Figure 3 the left and right sides in

[0033] ). When the two clamping arms close towards each other, the clamping ends of the two clamping arms are respectively clamped into the grooves on both sides of the fixed block 10.

[0034] In a specific embodiment, as Figure 3 shown, the transmission part includes: a push rod 2, a pressure rod 4 and a first reset component. Among them, one end (the rear end) of the push rod 2 is connected to the bottom of the push block 1, and the other end (the front end) of the push rod 2 is connected to the middle area of the pressure rod 4; both ends of the pressure rod 4 are connected to the non-clamping ends of the two clamping arms, and the two clamping arms are used to open in opposite directions when subjected to the pressure of the pressure rod 4, and close towards each other when the pressure of the pressure rod 4 disappears; the first reset component is connected to the pressure rod 4 and is used to generate an elastic force when the pressure rod 4 is pushed by the thrust provided by the push block 1, and use the elastic force to drive the pressure rod 4 to reset when the thrust provided by the push block 1 disappears.

[0035] In this embodiment, by pushing the push block 1 to drive the push rod 2 to move, the push rod 2 will drive the pressure rod 4 to move when moving, and the pressure rod 4 will drive the two clamping arms to act when moving, and their respective clamping ends will open in opposite directions, thereby loosening the fixed block 10; release the push block 1, at this time the thrust applied to the push block 1 disappears, and the two clamping arms are reset under the action of the elastic force provided by the first reset component, and their respective clamping ends close towards each other, thereby clamping the fixed block 10.

[0036] In a specific embodiment, as Figure 3 shown, the first reset component includes: a slide rod 19, a first elastic element and a stopper 11. The slide rod 19 is slidably connected to the pressure rod 4, the stopper 11 and the push block 1 are respectively located on the front and rear sides of the pressure rod 4, the end of the slide rod 19 is connected to the stopper 11, and one end of the first elastic element is connected to the pressure rod 4 and the other end is connected to the stopper 11.

[0037] Specifically, the sliding rod 19 can pass through the pressing rod 4, so that the sliding rod 19 is slidably connected inside the pressing rod 4, and the end (front end) of the sliding rod is connected to the stopper 11. The sliding rod 19 can be arranged directly below the push rod 2.

[0038] The first elastic element can be a compression spring 3. The compression spring 3 is sleeved on the sliding rod 19, and one end of the compression spring 3 is connected to the pressing rod 4, and the other end of the compression spring 3 is connected to the stopper 11. The compression spring 3 can generate elastic force when squeezed by the pressing rod 4 and the stopper 11.

[0039] The bottom of the stopper 11 is connected to the corresponding position on the inner wall of the bottom of the base 9, and the end of the sliding rod 19 is connected to the stopper 11, so the sliding rod 19 is fixed in the base 9 through the stopper 11.

[0040] In this embodiment, the pressing rod 4 is reset under the action of elastic force through the sliding rod 19, the first elastic element and the stopper 11, and then the push block 1 is driven to reset by the push rod 2.

[0041] In a specific embodiment, as Figure 3 shown, each clamping arm includes: a connecting rod 5, a slider 6 and a fixing plate 8. One end of the connecting rod 5, as the non-clamping end of the clamping arm, is rotatably connected to the corresponding end of the pressing rod 4, the other end of the connecting rod 5 is rotatably connected to the slider 6, the slider 6 is also slidably connected to the fixing plate 8, and the end of the slider 6 opposite to the fixed block 10 is used as the clamping end of the clamping arm.

[0042] Among them, the left and right ends of the pressing rod 4 are respectively rotatably connected to one end (rear end) of two connecting rods 5, and the other ends (front ends) of the two connecting rods 5 are respectively rotatably connected to two sliders 6. The two sliders 6 are respectively slidably connected to two fixing plates 8, and each slider 6 can move left and right along a corresponding fixing plate 8.

[0043] In this embodiment, when the two connecting rods 5 move forward, they will drive the two sliders 6 to move in opposite directions along the two fixing plates 8 to release the fixed block 10; when the two connecting rods 5 move backward, they will drive the two sliders 6 to move in opposite directions along the two fixing plates 8 to clamp the fixed block 10.

[0044] In a specific embodiment, as Figure 3 shown, each clamping arm further includes: a clamping block 7. The clamping block 7 adopts a U-shaped structure, and the fixing plate 8 extends into the inside of the clamping block 7 from the opening of the U-shaped structure and is slidably connected to the clamping block 7. The clamping block 7 is also connected to the slider 6, and the bottom end of the U-shaped structure of the clamping block 7 is used as the clamping end of the clamping arm.

[0045] In this embodiment, both of the two clamping blocks 7 are U-shaped structures, and the openings of the U-shaped structures of the two clamping blocks 7 are arranged in opposite directions. Correspondingly, the bottoms of the U-shaped structures of the two clamping blocks 7 are arranged opposite to each other. The front ends of the two sliders 6 are respectively connected to the same side surface of the U-shaped structures of the two clamping blocks 7. The two clamping blocks 7 are respectively slidably connected to the two fixing plates 8 extending into them, so that the outer circumferences of the two fixing plates 8 are respectively slidably connected inside the two clamping blocks 7.

[0046] In a specific embodiment, as Figures 1 to 3 shown, the quick-release mechanism further includes: a hollow base 9.

[0047] Specifically, the base 9 is a hollow structure, and a first cavity 20 is arranged inside it. The push block 1, the clamping assembly, and the fixing block 10 are all located in the first cavity 20 of the base 9.

[0048] The two fixing plates 8 are respectively located on the left and right sides inside the base 9. The left end of the fixing plate 8 located on the left side inside the base 9 is connected to the left inner wall of the base 9, the bottom of the fixing plate 8 located on the left side inside the base 9 is connected to the corresponding position of the bottom inner wall of the base 9, the right end of the fixing plate 8 located on the right side inside the base 9 is connected to the right inner wall of the base 9, and the bottom of the fixing plate 8 located on the right side inside the base 9 is connected to the corresponding position of the bottom inner wall of the base 9.

[0049] At the position on the upper surface of the base 9 corresponding to the push block 1 (i.e., Figure 1 the right side of the upper surface of the base 9 in

[0050] ), a moving hole 21 is opened. The top of the push block 1 extends outwards from the moving hole 21 and can move back and forth in the moving hole 21. The moving hole 21 can provide a pushing space for pushing the push block 1, so that the push block 1 slides in the moving hole 21 on the upper surface of the base 9. At the position on the upper surface of the base 9 corresponding to the fixing block 10, a taking-out hole (not marked in the figure) is opened, and the size of the taking-out hole is slightly larger than the size of the fixing block 10.

[0051] It should be noted that the fact that the size of the taking-out hole is slightly larger than the size of the fixing block 10 means that the difference between the size of the taking-out hole and the size of the fixing block 10 is less than a preset value. As for the specific value of the preset value, those skilled in the art can set and adjust it according to the actual situation, as long as it satisfies that the fixing block 10 can pass through the taking-out hole smoothly to take out from the base 9 and can pass through the taking-out hole smoothly to be placed into the base 9.

[0051] In this embodiment, by setting the base 9, it can not only better protect the push block 1, the clamping assembly, and the fixing block 10, but also facilitate the user to push the push block 1 to clamp and release the signal transmission device, which is convenient for the user to operate.

[0052] In a specific embodiment, as Figure 1 and Figure 2As shown, the signal transmission device 13 includes a device body, a housing, and a dust-proof net 18.

[0053] Specifically, the device body is disposed within the housing, and the dust-proof net 18 is disposed on one side of the housing for preventing dust from entering. The dust-proof net 18 is slidably connected to one side of the housing. Through holes 24 are formed in the housing at positions corresponding to the sides of the dust-proof net 18, and grooves 22 are formed in the sides of the dust-proof net 18 at positions corresponding to the through holes 24 (i.e., Figure 4 the left side of the dust-proof net 18 in the figure).

[0054] As Figure 1 、 Figure 2 and Figure 4 shown, the quick-release mechanism further includes: a pull rod 14 and a second reset assembly. The pull rod 14 and the second reset assembly may be referred to as the second disassembly assembly.

[0055] Among them, the pull rod 14 sequentially passes through the second reset assembly and the through hole 24 on the housing of the signal transmission device, and is inserted into the groove 22 on the side of the dust-proof net 18 to fix the dust-proof net 18 on the housing. Equivalently, through holes 24 are formed on one side of the housing of the signal transmission device close to the pull rod 14. The second reset assembly is connected to the housing and is configured to generate an elastic force under the action of the pulling force provided by the pull rod 14 when the pull rod 14 moves away from the signal transmission device, and to drive the pull rod 14 to reset by using the elastic force when the pulling force provided by the pull rod 14 disappears.

[0056] In this embodiment, the end of the pull rod 14 is slidably connected to the groove 22 on the side of the dust-proof net 18. When the pull rod 14 is pulled, the end of the pull rod 14 slides out of the groove 22 on the side of the dust-proof net 18 to facilitate the disassembly of the dust-proof net 18. At the same time as the pull rod 14 is pulled, the second reset assembly generates an elastic force; when the pull rod 14 is released, the end of the pull rod 14 resets under the action of the elastic force and is inserted into the groove 22 on the side of the dust-proof net 18 again.

[0057] In a specific embodiment, as Figure 4 shown, the second reset assembly includes: a housing 12, a second elastic element, and a push plate 17. The second elastic element and the push plate 17 are both disposed within the housing 12. The push plate 17 is sleeved on the pull rod 14. The pull rod 14 passes through the housing 12 and both ends extend out from both sides of the housing 12. One end of the second elastic element is connected to the inner surface of the side of the housing 12 away from the signal transmission device, and the other end is connected to the push plate 17.

[0058] It should be noted that the size of the push plate 17 should be larger than the size of the two through holes on the housing 12 for passing the pull rod 14, so that the push plate 17 is restricted within the housing 12 and will not escape from the housing 12 through these two through holes.

[0059] Among them, the housing 12 is a hollow structure, and a second cavity 23 is provided therein. Both the second elastic element and the push plate 17 are located in the second cavity 23 of the housing 12. The housing 12 serves to protect the second elastic element and the push plate 17. The second cavity 23 can provide a pulling space for the pull rod 14 to pull the push plate 17.

[0060] A pull rod 14 is slidably connected inside the housing 12, and the push plate 17 is sleeved on one end of the pull rod 14 close to the signal transmission device 13.

[0061] The second elastic element can be a spring 16. The spring 16 is sleeved on the pull rod 14, and one end of the spring 16 is connected to the inner surface of the side of the housing 12 away from the signal transmission device, and the other end of the spring 16 is connected to the push plate 17.

[0062] In this embodiment, pulling the pull rod 14 will drive the push plate 17 to move together in a direction away from the signal transmission device 13. At this time, the push plate 17 will compress the spring 16, and the spring 16 will compress the inner wall of the housing 12 to generate elastic force. Continue to pull the pull rod 14 until the pull rod 14 slides out of the groove on the side of the dust-proof net 18. At this time, the dust-proof net 18 can be disassembled.

[0063] In a specific embodiment, a pull cap 15 is provided at one end of the pull rod 14 away from the signal transmission device 13.

[0064] In this embodiment, one end of the pull rod 14 is inserted into the groove on the side of the dust-proof net 18, and the other end of the pull rod 14 is connected to the pull cap 15. By providing the pull cap 15, the pull rod 14 can be pulled more conveniently.

[0065] The following will Figures 1 to 4 describe in detail the working principle of the quick-release mechanism of the present utility model:

[0066] When it is necessary to disassemble the signal transmission device 13, by pushing the push block 1 to drive the push rod 2 to move, when the push rod 2 moves, it will drive the pressure rod 4 to move. When the pressure rod 4 moves, it will compress the pressure spring 3, and the pressure spring 3 will compress the stop block 11 to generate elastic force. While the pressure rod 4 moves, it will also drive two connecting rods 5 to move. When the two connecting rods 5 move, they will drive two sliders 6 to slide. When the two sliders 6 slide, they will drive two clamping blocks 7 to slide along the outer circumferences of two fixing plates 8 respectively. When the two clamping blocks 7 slide out of the grooves on both sides of the fixing block 10, the two clamping arms open, and the fixing block 10 can be taken out from the extraction hole on the upper surface of the base 9. Because the fixing block 10 is fixed to the signal transmission device 13, the signal transmission device 13 can also be taken out together. At this time, if the push block 1 is released, the push block 1 will drive other structures back to the initial position due to the elastic force of the pressure spring 3.

[0067] When the signal transmission device 13 needs to be installed, first fix the base 9 at the place where the signal transmission device 13 needs to be installed. Then, push the push block 1. The push block 1 will drive the push rod 2, the pressure rod 4, the two connecting rods 5, the two sliders 6 and the two clamping blocks 7 to move in sequence. At this time, the two clamping arms will open. Align the grooves on the left and right sides of the fixing block 10 with the ends of the two clamping blocks 7, and then release the push block 1. The clamping blocks 7 will be stuck in the grooves on the left and right sides of the fixing block 10, thus realizing the quick installation of the signal transmission device 13.

[0068] When the dust-proof net 18 needs to be disassembled, the push plate 17 can be driven to move by pulling the pull rod 14. While the push plate 17 is moving, it will squeeze the spring 16. The spring 16 will squeeze the inner wall of the housing 12 to generate an elastic force. When the pull rod 14 is continuously pulled until it slides out of the groove 22 on the side of the dust-proof net 18, the dust-proof net 18 can be disassembled. After the disassembly is completed, release the pull rod 14. At this time, the pull rod 14 will bounce back to the initial position due to the elastic force of the spring 16.

[0069] The quick-release mechanism for a signal transmission device provided by the embodiment of the present utility model realizes the quick disassembly of the signal transmission device by pushing the push block to open the two clamping arms and then releasing the fixing block. At this time, when the push block is released, the push block will drive other structures back to the initial position due to the elastic force, thus realizing the effect of quickly installing the signal transmission device; by pulling the pull rod until the pull rod slides out of the groove on the side of the dust-proof net, the dust-proof net can be disassembled. At this time, when the pull rod is released, the pull rod will return to the initial position due to the elastic force, solving the problem of quickly disassembling the dust-proof net.

[0070] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some 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 utility model.
