DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1 As shown, a modem device for communication transmission includes a device body, which includes an upper shell 100 and a lower shell 200; wherein the upper shell 100 and the lower shell 200 are slidably connected; a mounting plate 300 is further provided on the upper shell 100, and the mounting plate 300 is slidably connected to the upper shell 100;

[0031] like Figure 3As shown, a mounting groove 400 is provided in the middle of the upper housing 100; a slide groove 500 is provided on the inner wall of the mounting groove 400, and a rotation groove 600 is provided at the end of the slide groove 500, and the rotation groove 600 is connected to the slide groove 500; a rotation column 700 is provided on the side of the mounting plate 300, and the rotation column 700 is slidably provided inside the slide groove 500;

[0032] like Figure 1 and Figure 2 As shown, a plurality of heat dissipation gaps 800 are provided on the mounting plate 300, and the heat dissipation gaps 800 are connected to the device body; a fixing protrusion 900 is also provided on the side of the mounting plate 300, and the fixing protrusion 900 cooperates with the slide groove 500 to fix the mounting plate 300 and the upper shell 100.

[0033] In this utility model, the sliding connection between the upper housing 100 and the lower housing 200, as well as the sliding arrangement of the mounting plate 300 within the upper housing 100, provide a high degree of structural flexibility. This design allows the device to be adjusted to different operating conditions, thus adapting to various communication environments. The design of the slide groove 500 and the rotation groove 600 allows the mounting plate 300 to slide easily within the upper housing 100. Sliding the mounting plate 300 opens the interior of the device, effectively reducing maintenance costs and time, and improving the device's maintainability.

[0034] The heat dissipation gap 800 provided on the mounting plate 300 and the connection with the device body enhances the device's heat dissipation performance, promptly dissipating heat generated during operation, helping to maintain the device's stability and extend its service life. The fixed protrusions 900 and the slide grooves 500 effectively secure the mounting plate 300 to the upper housing 100, reducing instability caused by vibration or movement and improving the device's reliability during operation.

[0035] Example 2

[0036] This embodiment is a further refinement of the first embodiment.

[0037] like Figure 2 As shown, the upper shell 100 is sleeved on the outside of the lower shell 200 , and a boss 110 is further provided on the lower shell 200 . The boss 110 cooperates with the lower end of the upper shell 100 to limit the sliding of the upper shell 100 .

[0038] When the upper shell 100 is in contact with the lower shell 200 (i.e., when the upper shell 100 is not lifted), the upper shell 100 and the lower shell 200 are in abutment state, and the lower end of the upper shell 100 is limited by the boss 110 provided on the lower shell 200.

[0039] like Figure 2As shown, an opening 111 is further provided on the side of the upper housing 100, and a plurality of baffles 112 are provided in the middle of the opening 111, forming a flow channel between adjacent baffles 112. The baffles 112 are provided to tilt outward.

[0040] like Figure 2 As shown, openings 111 are provided on the left and right sides of the upper shell 100 , and a plurality of inclined baffles 112 are provided inside the openings 111 . The inclined baffles 112 can play a certain filtering role to prevent debris from being sucked into the interior of the device.

[0041] Furthermore, there are 12 to 16 baffles 112 .

[0042] A mounting cavity 113 is provided inside the lower housing 200 , and the mounting cavity 113 is used for mounting a circuit board.

[0043] like Figure 3 As shown, a plurality of mounting portions 118 are provided at the rear end of the mounting cavity, and the mounting portions 118 are used for mounting the connectors.

[0044] like Figure 4 As shown, a first mounting post 114 is provided inside the mounting cavity of the lower housing 200, and a second mounting post 115 is provided inside the upper housing 100. The second mounting post 115 is sleeved around the outside of the first mounting post 114 and slidably connected to the first mounting post 114. A telescopic rod 116 is provided inside the first mounting post 114. One end of the telescopic rod 116 is fixedly connected to the first mounting post 114, and the other end of the telescopic rod 116 is fixedly connected to the second mounting post 115.

[0045] Specifically, mounting holes are provided inside the first mounting column 114 and the second mounting column 115, and the first mounting column 114 and the second mounting column 115 are connected. One end of the telescopic rod 116 is fixedly provided inside the first mounting column 114, and the other end of the telescopic rod 116 extends to the inside of the second mounting column 115. The telescopic rod 116 is extended and retracted up and down, thereby pushing the upper shell 100 to rise, and then the opening 111 is separated from the obstruction of the side wall of the lower shell 200, so that a flow channel is formed between adjacent baffles 112 to connect the mounting cavity with the outside, thereby improving the heat dissipation effect inside the mounting cavity.

[0046] like Figure 4 As shown, a plurality of supporting legs 117 are provided below the lower housing 200 , and the supporting legs 117 are used to support the lower housing 200 .

[0047] Specifically, there are four supporting legs 117 , which are respectively arranged at the four ends of the lower shell 200 to support the device.

[0048] A mounting portion 118 is further provided at the rear end of the lower housing 200 , and the mounting portion 118 is used for mounting a connector.

[0049] Specifically, the mounting portion 118 is provided at the rear end of the lower housing 200 . There are multiple mounting portions 118 , and the multiple mounting portions 118 can be used to install different connectors to accommodate different line connections.

[0050] An indicator light hole 119 is also provided on the upper housing 100 , and the indicator light hole 119 is used for indicating the signal of the indicator light.

[0051] Further, such as Figure 5 As shown, in order to improve the heat dissipation effect of the device, a heat dissipation fan is further provided below the mounting plate 300 to improve the heat dissipation effect inside the mounting cavity.

[0052] Further, such as Figure 6 and Figure 7 As shown, the slide groove 500 is connected to the rotating groove 600; wherein, the height of the slide groove 500 is smaller than the diameter of the rotating groove 600 (for example, the height of the slide groove 500 is 4 mm, and the diameter of the rotating groove 600 is 7 mm); such an arrangement enables the rotating column 700 on the mounting plate 300 to only slide inside the slide groove 500 and rotate inside the rotating groove 600.

[0053] Furthermore, the fixing protrusion 900 provided on the side of the mounting plate 300 cooperates with the first slide groove. When the end of the mounting plate 300 slides into the interior of the mounting groove 400 and abuts against the inner wall of the mounting groove 400, the fixing protrusion 900 slides into the interior of the slide groove 500, limiting the mounting plate 300 and the upper shell 100.

[0054] Furthermore, the slide groove 500 includes a first slide groove and a second slide groove; and the length of the first slide groove is shorter than the length of the second slide groove (for example, the first slide groove is 3 cm, and the second slide groove is 8 cm), to ensure that the fixed protrusions 900 set on the side of the mounting plate 300 all slide out of the first slide groove to avoid affecting the subsequent rotation.

[0055] Optionally, in order to prevent the mounting plate 300 from directly detaching from the upper shell 100, the height of the first slide groove can be set to be smaller than the height of the second slide groove, and the height of the first slide groove matches the height of the fixed protrusion 900; the height of the second slide groove is matched with the height of the rotating column 700, so that the rotating column 700 can only slide in the second slide groove and rotate in the rotating groove 600.

[0056] The working principle of the present utility model is: when the device body needs to work normally, it is connected to the connector through the mounting portion 118 arranged at the rear end of the lower shell 200, and the working status of the device is indicated through the indicator light hole 119, and the heat is dissipated inside the device body through the heat dissipation gap 800 arranged on the mounting plate 300.

[0057] When the device body needs to work at high intensity, the telescopic rod 116 can be used to push the upper shell 100 to move upward (the upper shell 100 and the lower shell 200 remain connected, that is, in this state, the upper shell 100 and the lower shell 200 are not separated), so that the opening 111 set on the side of the upper shell 100 is separated from the obstruction of the side wall of the lower shell 200; so that a flow channel is formed between adjacent baffles 112 to connect the installation cavity and the outside, thereby improving the heat dissipation effect inside the installation cavity 113 and ensuring the needs of high-intensity operation of the device body.

[0058] When the device needs to be repaired, the user only needs to pull the mounting plate 300 and slide it out of the mounting slot 400 of the upper housing 100 to open the device body, avoiding the need to disassemble the upper housing 100 and the lower housing 200, thus saving maintenance time. By rotating the mounting plate 300, the cooling fan located below the mounting plate 300 can be installed or removed, making it easier to install and remove the cooling fan.

[0059] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
