Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a switch. Background Technology

[0002] A switch is a network device that operates at the data link layer (Layer 2) of the OSI reference model. It connects multiple network devices (such as computers, servers, and printers) to enable intelligent forwarding of data frames and network communication. In current technology, the installation and fixing methods of switches, as key network communication devices, directly affect ease of use and stability. The current mainstream switch installation structures have the following problems: traditional switches mostly use fixed brackets or screws for direct fastening, which can only adapt to a single installation scenario (such as horizontal fixing in a server rack or vertical fixing on a wall). They cannot flexibly adjust the installation angle and position according to the actual spatial layout (such as narrow corners, sloping walls, or desktop edges), making deployment difficult in complex environments (such as office cubicles, industrial control cabinets, and home electrical boxes). Therefore, improvements to existing technologies are needed. Utility Model Content

[0003] The purpose of this invention is to provide a switch to solve the problems mentioned in the background art.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 As shown, a switch includes a switch housing 1, inside which a switch 18 is assembled. A support arm 4 is assembled on the rear side wall of the switch housing 1, and an adjusting cylinder 5 is assembled at the end of the support arm 4. An installation plate 8 is assembled at the end of the adjusting cylinder 5. A hinge cylinder b7 is installed on the side wall of the installation plate 8, and a hinge shaft b6 is installed at the end of the adjusting cylinder 5. The hinge shaft b6 is installed inside the hinge cylinder b7. One end of the support arm 4 is inserted into the interior of the adjusting cylinder 5, and the other end of the support arm 4 is vertically mounted with a hinge shaft a3. A hinge cylinder a9 is assembled at the bottom end of the hinge shaft a3. A snap-fit ​​mechanism 2 is assembled between the hinge cylinder a9 and the switch housing 1. The snap-fit ​​mechanism 2 includes a mating block 10 installed at the bottom end of the hinge cylinder a9. A mating groove 11 is opened on the front side of the upper end of the mating block 10. A sleeve block 13 is installed on the rear side wall of the switch housing 1, and a mating opening 17 is opened at the bottom end of the sleeve block 13. The mating opening 17 is snapped into the mating groove 11.

[0020] In practical implementation, the switch housing 1 is integrally injection molded from ABS engineering plastic, possessing flame-retardant and impact-resistant properties. Its interior forms a closed cavity to house the switch 18 (including the core processing module, port circuits, etc.), providing dustproof, moisture-proof, and physical protection for the internal components. A support arm 4 is screwed to the rear wall of the switch housing 1. The support arm 4 is made of 6061 aluminum alloy, offering lightweight and high strength. One end engages with the adjusting cylinder 5, and the other end connects to the switch housing 1 via a hinge structure, forming the core framework for installation support. The adjusting cylinder 5 is a hollow cylindrical structure, made of the same material as the support arm 4. A hinge shaft b6 is welded to the end furthest from the support arm 4. The hinge shaft b6 can rotate freely within the hinge cylinder b7 on the side wall of the mounting plate 8, allowing the adjusting cylinder 5 to rotate 360° horizontally relative to the mounting plate 8, facilitating adaptation to different installation orientations. A hinge shaft a3 is vertically welded to the end of the support arm 4 away from the adjusting cylinder 5. The bottom end of the hinge shaft a3 is inserted into the hinge cylinder a9, allowing the support arm 4 to rotate 180° vertically relative to the hinge cylinder a9. Combined with the horizontal rotation of the hinge shaft b6, this allows the switch housing 1 to flexibly adjust its angle in three-dimensional space, meeting the installation requirements of complex scenarios. The snap-fit ​​mechanism 2 is a key component connecting the hinge cylinder a9 and the switch housing 1: the mating block 10 is fixed to the bottom end of the hinge cylinder a9 with screws, and the mating groove 11 on the front side of its upper end has a U-shaped structure; the bottom end of the sleeve block 13 welded to the rear side wall of the switch housing 1 has a mating opening 17 that matches the mating groove 11. When the mating opening 17 is snapped into the mating groove 11, the hinge cylinder a9 and the switch housing 1 can be quickly pre-positioned, avoiding component misalignment during installation.

[0021] In some technical solutions, drive cavities 14 are provided at both ends of the rear sidewall of the sleeve block 13, and screw holes 15 are provided at the center of the sidewall of the drive cavity 14. Screw grooves 12 are provided at both ends of the front sidewall of the mating block 10, and bolt bodies 16 are screwed into the screw holes 15 and screw grooves 12.

[0022] In the specific implementation process, in order to enhance the connection stability of the snap-fit ​​mechanism 2, drive cavities 14 are symmetrically opened at both ends of the rear sidewall of the sleeve block 13. A screw hole 15 is opened at the center of the inner sidewall of the drive cavity 14, and a screw groove 12 is opened at the corresponding position on the front sidewall of the mating block 10. The bolt body 16 is made of 304 stainless steel, and its screw part is screwed into the screw hole 15 and the screw groove 12, while the head is accommodated in the drive cavity 14. The sleeve block 13 and the mating block 10 are rigidly connected by thread engagement. Combined with the initial snap-fit ​​positioning, a double fixing structure of snap-fit ​​and screw connection is formed to avoid the loosening problem caused by single snap-fit.

[0023] In some technical solutions, a circular groove 161 is provided at the bottom end of the bolt body 16, and a bolt rod 163 is vertically installed inside the circular groove 161. The bolt rod 163 is screwed into the bolt hole 15 and the bolt groove 12.

[0024] In practical implementation, a circular groove 161 is provided at the bottom of the bolt body 16 for easy operation with an internal hex wrench; a bolt shank 163 is integrally formed vertically at the center of the circular groove 161, and the bolt shank 163 passes through the threaded hole 15 and is screwed into the threaded groove 12 to achieve the fastening of the sleeve block 13 and the mating block 10. This structure ensures connection accuracy through standardized thread design, while the internal hexagonal groove avoids the problem of traditional external hexagonal bolts being easily damaged by impact, thus improving operational convenience.

[0025] In some technical solutions, a fixing ring 166 is installed on the upper outer end of the bolt rod 163, and an annular pressure plate 165, a spring 167 and an annular rubber sheet 162 are fitted on the circumferential surface of the bolt rod 163. An extrusion block 164 is installed at the upper edge of the annular rubber sheet 162.

[0026] In the specific implementation process, a fixing ring 166 is welded to the upper outer end of the bolt rod 163 to limit the axial displacement of the upper component; the circumferential surface of the bolt rod 163 is fitted with an annular rubber sheet 162, a spring 167, and an annular pressure plate 165 from bottom to top. The upper edge of the annular rubber sheet 162 has an integrally formed extrusion block 164. When the bolt body 16 is tightened, the spring 167 is compressed by the annular pressure plate 165, generating a continuous preload. The extrusion block 164 is embedded in the inner wall of the drive cavity 14 of the sleeve block 13, and together with the elastic deformation of the annular rubber sheet 162, it absorbs vibration energy, effectively preventing the bolt from loosening due to equipment operation or environmental vibration. It is particularly suitable for vibration environments such as industrial workshops and machine rooms.

[0027] In some technical solutions, a heat sink 21 is installed on the top of the switch housing 1.

[0028] In the specific implementation process, a heat sink 21 is mounted on the top of the switch housing 1 using thermally conductive silicone adhesive or screws. The heat sink 21 is made of aluminum extrusion and has 20 fins on its surface. The bottom of the heat sink contacts the heat-generating components inside the switch housing 1 through a thermal pad. This design utilizes the high thermal conductivity of aluminum alloy to quickly conduct internal heat to the fins, which is then dissipated through air convection, compared to traditional structures that rely solely on the housing for heat dissipation.

[0029] In some technical solutions, the front end of the switch housing 1 is provided with an insertion cavity 19, and the side wall of the switch housing 1 is provided with an interface cavity 20.

[0030] In practical implementation, the front of the switch housing 1 has a socket 19, which integrates 8-24 RJ45 network ports. The opening faces forward for easy plugging and unplugging of network cables. The side wall (right or left side) of the switch housing 1 has an interface cavity 20, which contains a power interface, a console configuration port, and indicator lights. The positions of the socket 19 and interface cavity 20 avoid the support arm 4 and the snap-fit ​​mechanism 2 on the rear side wall, ensuring that cable plugging and unplugging are not obstructed by the installation structure when the switch housing 1 is adjusted to any angle, thus improving operational convenience.

[0031] In some technical solutions, the adjusting cylinder 5 and the support arm 4 are interference fit.

[0032] In practical implementation, this structure requires no additional locking components and achieves stepless length adjustment through mechanical cooperation, adapting to different installation distances. Compared with sliding rail adjustment, it is simpler and lower in cost.
