Description

Technical Field

[0001] The utility model relates to the technical field of hubs, and specifically relates to a protective housing for a hub. Background Art

[0002] The English name of a hub is "Hub". "Hub" means "center". The main function of a hub is to regenerate, reshape and amplify the received signal to expand the transmission distance of the network, and at the same time concentrate all nodes on the node centered on it. It works at the first layer of the OSI (Open System Interconnection Reference Model), that is, the "physical layer". Like network cards, network cables and other transmission media, a hub belongs to the basic equipment in a local area network and adopts the CSMA / CD (Carrier Sense Multiple Access with Collision Detection) medium access control mechanism.

[0003] In our life, hubs can be seen everywhere, but the hubs on the market are generally exposed, so when the hub contacts the outside world, it is easy to be damaged. And after the hub is plugged into an external interface, if it is pulled by an external force, the plug connector is likely to fall off from the plug interface, thus affecting subsequent use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a protective housing for a hub to solve the problems existing in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A protective housing for a hub, including a protective shell, further including:

[0006] Limiting plates rotatably connected to both sides of the top of the protective shell. Sliding grooves are opened in the front, back, left and right of both sides of the protective shell. Sliders are slidably connected inside the sliding grooves. A folding plate for limiting the limiting plates is rotatably connected between the front and back sliders;

[0007] A number of first springs fixed to the bottom of the inner cavity of the protective shell. The top of the first spring is fixed with a support plate, and a hub body is arranged above the support plate;

[0008] A number of moving grooves opened on the surface of the protective shell. A fixed rod is fixed inside the moving groove. A moving block is movably connected to the surface of the fixed rod. A second spring is sleeved and connected to the surface of the fixed rod. Two ends of the second spring are respectively fixed between the moving block and the bottom of the inner cavity of the moving groove. A baffle is fixed to the surface of the moving block.

[0009] Preferably, fastening bolts for limiting the position of the folding plate are threadedly connected to the front and back of the top of the folding plate.

[0010] Preferably, movable grooves are formed in the front and rear of both sides of the inner cavity of the protective shell. Movable blocks are fixedly connected to the front and rear of both sides of the support plate, and the surface of the movable block is slidably connected to the inside of the movable groove.

[0011] Preferably, a soft pad is fixed to the bottom of the limiting plate, and the soft pad is made of rubber.

[0012] Preferably, a plurality of heat dissipation holes are formed in both sides of the protective shell, and the heat dissipation holes on both sides are symmetrically distributed.

[0013] Preferably, a push plate is fixed to the surface of the baffle.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, through the arrangement that limiting plates are hinged to both sides of the top of the protective shell, after the hub body is placed inside the protective shell, the limiting plates can be rotated to press the top of the hub body. Subsequently, the folded plate is slid above the limiting plate to limit the limiting plate, so as to facilitate the subsequent disassembly and assembly between the hub body and the protective shell. At the same time, through the elastic force of the second spring itself, the moving block and the baffle can be driven to move upward, so as to facilitate the limitation of the plug connector inserted on the surface of the hub body and prevent the phenomenon of slipping.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 As shown, a protective shell of a hub includes a protective case 1. Both sides of the top of the protective case 1 are rotatably connected with limit plates 2. The front and rear sides of both sides of the protective case 1 are provided with sliding grooves 3. A slider 4 is slidably connected inside the sliding groove 3. A folding plate 5 for limiting the limit plate 2 is rotatably connected between the front and rear sliders 4. A plurality of first springs 7 are fixed at the bottom of the inner cavity of the protective case 1. A support plate 8 is fixed at the top of the first spring 7. Above the support plate 8 is provided a hub body 12. A plurality of moving grooves 13 are provided on the surface of the protective case 1. A fixing rod 14 is fixed inside the moving groove 13. A moving block 15 is movably connected to the surface of the fixing rod 14. A second spring 16 is sleeved and connected to the surface of the fixing rod 14. Both ends of the second spring 16 are fixed between the moving block 15 and the bottom of the inner cavity of the moving groove 13. A baffle 17 is fixed on the surface of the moving block 15.

[0024] Threaded connections are provided at the front and rear of the top of the folding plate 5 with fastening bolts 6 for limiting the position of the folding plate 5. After the folding plate 5 limits the top of the limit plate 2, the fastening bolts 6 can be rotated so that the bottom end of the fastening bolts 6 fits and fixes with the top of the limit plate 2. In this way, not only the effect of limiting the limit plate 2 is improved, but also the random movement of the folding plate 5 is avoided.

[0025] Moving grooves 9 are provided at the front and rear of both sides of the inner cavity of the protective case 1. Moving blocks 10 are fixedly connected to the front and rear of both sides of the support plate 8. The surface of the moving block 10 is slidably connected to the inside of the moving groove 9. In this way, the support plate 8 can be supported and the stability during its up and down movement can be maintained.

[0026] A soft pad 18 is fixed at the bottom of the limit plate 2, and the soft pad 18 is made of rubber material. In this way, not only the friction between the limit plate 2 and the hub body 12 can be increased, but also the wear between them can be avoided.

[0027] A plurality of heat dissipation holes 11 are provided on both sides of the protective case 1, and the heat dissipation holes 11 on both sides are symmetrically distributed. In this way, the heat generated by the hub body 12 can be dissipated through the heat dissipation holes 11, which is convenient for subsequent use.

[0028] A push plate is fixed on the surface of the baffle 17, so that it is convenient for the user to have a force application point on the baffle 17 to drive the baffle 17 to be pushed downward.

[0029] It should be noted that in this technical solution, technical features such as... should be regarded as the prior art. For the specific structures, working principles, and possible control methods and spatial arrangement methods of these technical features, conventional selections in this field can be adopted, and this technical solution will not be further elaborated specifically.

[0030] Working principle: When in use, the hub body 12 can be placed inside the protective shell 1. Then, slide the folding plates 5 on both sides to the middle position. Next, flip the limiting plate 2 to the top surface of the hub body 12. Subsequently, slide the folding plate 5 above the limiting plate 2 so that the folding plate 5 can limit the position of the limiting plate 2. At the same time, through the elastic force of the first spring 7 itself, it can drive the support plate 8 to always move upward and drive the hub body 12 to move together. In this way, the top of the hub body 12 can always be in contact with the bottom of the limiting plate 2, thereby improving the fixing effect. After that, apply a downward force to the baffle 17 so that the insertion interface on the surface of the protective shell 1 is exposed. Then, insert the plug through the insertion interface on the surface of the protective shell 1 and plug it into the hub body 12. After the insertion is completed, through the elastic force of the second spring 16 itself, it can drive the moving block 15 and the baffle 17 to move upward so that the baffle 17 limits the plug.
