Description

Technical Field

[0001] The utility model relates to the technical field of network security protection equipment, and in particular to a security protection terminal with a dustproof structure. Background Art

[0002] Network security protection is a network security technology that refers to technical means dedicated to solving problems such as how to effectively conduct intervention control and how to ensure the security of data transmission. It mainly includes physical security analysis technology, network structure security analysis technology, system security analysis technology, management security analysis technology, and other security services and security mechanism strategies. The network security protection terminal is an input and output device used for network security protection.

[0003] During long-term use, dust will enter the interior of the terminal. When the dust accumulates more and more, it will affect the normal operation of the internal electronic components, thereby causing failures and affecting the service life of the terminal. In order to improve the above problems, after searching, for example, a Chinese patent with patent application number 202322026666.1 provides a network security protection terminal with a dustproof structure, including a protective device, a base is installed on the left and right sides of the bottom surface of the protective device, and a heat dissipation port is opened on the left and right sides of the protective device. The outer surfaces of the heat dissipation port are respectively fixed with a dustproof net, and the terminal body is installed inside the front side of the protective device, and the left and right ends of the front side surface of the terminal body are respectively processed with push-pull blocks. The fixed frame can be pulled out of the limit slot by the pull rod, so that the staff can clean or replace the adsorption plate inside it, thereby avoiding the normal heat dissipation of the terminal body due to excessive dust adsorbed by the adsorption plate, and at the same time, the dustproof effect of the adsorption plate can be improved, and the adsorption plate made of rubber material can have a stronger dust adsorption capacity to achieve the purpose of efficient dust prevention.

[0004] Based on the above search, combined with the prior art, it is found that the connection ports of network security protection terminals with dustproof structures similar to those disclosed above are mostly directly exposed to the outside world, and dust easily falls into the inner side of the connection port where the connector is not connected, which is not conducive to the stable connection in the later stage; in addition, in order to enhance the heat dissipation performance, the existing network security protection terminals generally have heat dissipation fins fixedly installed on the outside of the shell, which is inconvenient to clean the dust falling between the heat dissipation fins. Therefore, a security protection terminal with a dustproof structure is proposed to improve the above problems. Utility Model Content

[0007] A dustproof mechanism is provided at the connection port, and the dustproof mechanism is installed on the outer wall of the terminal shell;

[0008] The dustproof mechanism includes a fixed block, a movable plate, a dustproof part and a compression spring. The fixed block is located at the lower side of the connection port and is fixed to the outer wall of the terminal housing. The movable plate is fixed to the upper end of the fixed block through the compression spring. The dustproof part is fixed to the lower end of the movable plate and covers the outer side of the connection port.

[0009] The side end of the terminal shell is provided with a heat dissipation port, and a dustproof net is detachably installed at the heat dissipation port;

[0010] The upper end surface of the terminal shell is equidistantly provided with a plurality of rectangular sliding holes, the inner sides of the plurality of rectangular sliding holes are vertically slidably mounted with heat dissipation fins, and the heat dissipation fins are elastically connected to the terminal shell.

[0011] As a further supplement to the present solution, the dustproof part is an elastic band, and the lower end of the dustproof part is fixed to the fixing block.

[0012] As a further supplement to the present solution, the dustproof mechanism further comprises a guide slide bar, one end of which is fixed to the fixed block, and the other end of which slides through the movable plate.

[0013] As a further supplement to the present solution, the width of the movable plate is greater than the width of the fixed block, and an anti-slip layer is provided on the upper end surface of the movable plate.

[0014] As a further supplement to the present solution, the dust screen is snap-connected to the inner side of the heat dissipation port, and the outer wall of the terminal shell is provided with a disassembly and assembly finger groove which is connected to the heat dissipation port.

[0015] As a further supplement to the present solution, a connecting block is fixed to the lower end of the heat dissipation fin, and a tension spring is fixed between the connecting block and the inner top end of the terminal housing.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: Reference Figure 1-4 A safety protection terminal with a dustproof structure shown in the figure comprises a terminal housing 1 with a plurality of connection ports 101 at the side end, a dustproof mechanism 3 is arranged at the connection port 101 , and the dustproof mechanism 3 is installed on the outer wall of the terminal housing 1 .

[0027] Regarding the dust prevention mechanism 3, specifically, Figure 4 As shown, the dustproof mechanism 3 includes a fixed block 31, a movable plate 32, a dustproof part 33 and a compression spring 34. The fixed block 31 is located at the lower side of the connecting port 101 and is fixed to the outer wall of the terminal shell 1. The movable plate 32 is fixed to the upper end of the fixed block 31 by the compression spring 34. The dustproof part 33 is fixed to the lower end of the movable plate 32 and covers the outer side of the connecting port 101.

[0028] Based on the coordinated arrangement of the above fixed block 31, movable plate 32, dustproof part 33 and compression spring 34, the movable plate 32 covers the outer side of the connection port 101 with the dustproof part 33 under the action of the compression spring 34 to protect the connection port 101 from dust. When it is necessary to insert an external connector, the movable plate 32 is manually pressed down with the connector to expose the connection port 101, and the connector can be inserted into the connection port 101.

[0029] A heat dissipation port 102 is provided at the side end of the terminal shell 1, and a dustproof net 2 is detachably installed at the heat dissipation port 102. Specifically, the dustproof net 2 is snapped onto the inner side of the heat dissipation port 102, and a disassembly and assembly finger groove 103 connected to the heat dissipation port 102 is provided on the outer wall of the terminal shell 1 to facilitate the disassembly and assembly of the dustproof net 2.

[0030] The upper end surface of the terminal housing 1 is equidistantly provided with a plurality of rectangular sliding holes 104, and the inner sides of the plurality of rectangular sliding holes 104 are vertically slidably mounted with heat dissipation fins 4, and the heat dissipation fins 4 are elastically connected to the terminal housing 1, specifically, as Figure 3 It is shown that a connecting block 5 is fixed to the lower end of the heat dissipation fin 4, and a tension spring 6 is fixed between the connecting block 5 and the inner top end of the terminal shell 1. When cleaning the upper end surface of the terminal shell 1, for example, when wiping with a rag, the heat dissipation fin 4 is forced to move downward until its upper end surface is flush with the upper end surface of the terminal shell 1, so that dust on the upper end surface of the terminal shell 1 and the heat dissipation fin 4 can be quickly and conveniently wiped off.

[0031] Since the heat dissipation fins 4 are in sliding contact with the terminal housing 1 , a stable heat conduction and heat dissipation effect can be ensured.

[0032] Among them, the dustproof part 33 is an elastic band, and the lower end of the dustproof part 33 is fixed to the fixing block 31. Compared with the ordinary plate-shaped dustproof structure, the elastic band can be compressed and will not occupy the position of the adjacent connection port 101 and the connection head when connecting the external connection head.

[0033] In order to ensure the fit between the dustproof part 33 and the surface of the terminal housing 1 to ensure the sealing and dustproof effect, the dustproof mechanism 3 also includes a guide slide 35, one end of which is fixed to the fixed block 31, and the other end of the guide slide 35 slides through the movable plate 32.

[0034] The width of the movable plate 32 is greater than that of the fixed block 31 , and an anti-slip layer is provided on the upper end surface of the movable plate 32 , so as to facilitate the smooth pressing down of the movable plate 32 during the connection operation.

[0035] Working principle of the utility model: in the use state, the movable plate 32 covers the outer side of the connection port 101 with the dustproof part 33 under the action of the compression spring 34, and the connection port 101 is dust-proof. When an external connection head needs to be inserted, the movable plate 32 is manually pressed down with the connection head to expose the connection port 101, and the connection head is inserted into the connection port 101; when cleaning the upper end surface of the terminal shell 1, for example, when wiping with a rag, the heat dissipation fin 4 is forced to move downward until its upper end surface is flush with the upper end surface of the terminal shell 1, so that dust on the upper end surface of the terminal shell 1 and the heat dissipation fin 4 can be quickly and conveniently wiped off. After wiping, the heat dissipation fin 4 is reset under the action of the tension spring 6.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
