Description

Technical Field

[0001] The utility model relates to the technical field of intelligent data terminals, and more specifically, to an automatic terminal data security protection device. Background Technique

[0002] An intelligent terminal is a terminal device embedded with a single-chip microcomputer or a microprocessor, having programmable functions and capable of completing data processing and data transmission control. Compared with non-intelligent terminals, it has the characteristics of being expandable, flexible in function and intelligent. An intelligent data terminal not only has certain functions, but also its basic functions can be increased or modified by the user through programming. A large amount of data is stored inside the automatic terminal.

[0003] After retrieval, a power distribution network real-time data communication security protection device with the existing publication number CN206283529U includes a master station. The master station includes a front-end machine and a public network front-end machine. The front-end machine is connected to the sub-station terminal through a dedicated communication, and the public network front-end machine is connected to the sub-station terminal through a wireless communication gateway. The sub-station terminal uploads the signal and telemetry data to the public network front-end machine. A one-way authentication based on the asymmetric key technology is adopted for the control command between the front-end machine and the sub-station terminal. The front-end machine of the automatic system master station adopts a security-reinforced operating system certified by the national designated department, and strict access control measures are taken. A security module should be configured on the front-end machine to sign the control command and parameter setting instruction to realize the identity authentication of the sub-station to the master station and the protection of the message integrity; for the communication of important sub-stations and terminals, two-way authentication encryption can be adopted to realize the two-way identity authentication between the master station and the sub-station, and ensure the confidentiality and integrity of the message.

[0004] Important data is stored inside the intelligent data terminal. When the terminal box body is plugged in and unplugged with the external data cable and power supply line, it is necessary to push and pull the terminal box body relative to the support frame, resulting in wear on the bottom of the box body. Moreover, the box body and the support frame are in sliding friction, and the frictional resistance is large, making it inconvenient to move. Therefore, we propose an automatic terminal data security protection device to solve the above existing problems. Content of the Utility Model

[0005] 1. Technical Problem to be Solved

[0006] In view of the problems existing in the prior art, the purpose of the present utility model is to provide an automatic terminal data security protection device. In the initial state, the casters inside the wheel grooves of the lower housing are flush with the bottom feet, and both are attached to the supporting surface of the support frame. When it is necessary to push and pull the automatic terminal, hold the traction frame and lift it longitudinally. The return spring undergoes elastic deformation within the elastic limit, the optical rod slides relative to the guide seat, and the bottom feet are separated from the supporting surface. Then, the lower housing can be horizontally pushed and pulled. The lower housing and the supporting surface have rolling friction through the casters, with small frictional resistance, making it more labor-saving to push and pull. Moreover, the surface of the lower housing in a suspended state relative to the supporting surface is not prone to wear, maintaining the integrity of the external structure, thereby performing security protection processing on the automatic terminal data.

[0007] 2. Technical solution

[0008] To solve the above problems, the present utility model adopts the following technical solutions.

[0009] An automatic terminal data security protection device includes a lower housing and an upper housing. The upper housing is installed on the surface of the lower housing through bolts. A slot is opened at the end face of the lower housing. Wheel grooves are opened at both side wall positions of the lower housing. A caster is rotatably connected inside the wheel groove, and a silica gel ring is sleeved outside the caster.

[0010] Guide seats are fixedly connected to both side wall positions of the upper housing. A guide hole is opened on the surface of the guide seat. An optical rod is inserted through the guide hole of the guide seat. The bottom end of the optical rod is fixedly connected with a bottom foot. A traction frame is erected at the top ends of the two optical rods.

[0011] Preferably, the caster is located at the inner side position of the wheel groove, and the caster is flush with the side wall of the lower housing.

[0012] Preferably, return springs are symmetrically installed on the surface of the upper housing, and the ends of the return springs are fixedly connected with the traction frame.

[0013] Preferably, positioning cylinders are symmetrically installed on the surface of the upper housing, and the positioning cylinders are located on one side of the return springs.

[0014] Preferably, a positioning rod is fixedly connected to the lower surface of the traction frame, and the positioning rod is inserted corresponding to the positioning cylinder.

[0015] Preferably, the traction frame and the two optical rods form an inverted U-shaped structure, and the traction frame and the optical rods are erected outside the lower housing and the upper housing.

[0016] Preferably, a protective pad is bonded to the end face of the upper housing, and buffer holes are opened on the surface of the protective pad.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) In the initial state of this scheme, the casters inside the wheel groove of the lower shell are flush with the bottom feet and are both fitted on the support surface of the support frame. When the automated terminal needs to be pushed or pulled, the traction frame is held and pulled longitudinally. The reset spring undergoes elastic deformation within the elastic limit, the light rod slides relative to the guide seat, and the bottom feet are separated from the support surface. The lower shell can be pushed or pulled horizontally. The lower shell and the support surface are subjected to rolling friction through the casters, and the friction resistance is small, making pushing and pulling more labor-saving. In addition, the surface of the lower shell that is suspended relative to the support surface is not prone to wear, thereby maintaining the integrity of the external structure, thereby providing security protection for the automated terminal data.

[0020] (2) After the push-pull movement is completed, the pulling force on the traction frame is removed. Under the elastic force of the return spring, the base is attached to the support surface, and the lower shell is protected from side slip. The traction frame can be pressed down, and the positioning rod and the positioning cylinder on the lower surface of the traction frame are plugged into each other to keep the base stable.

The traction frame 4 and the two groups of light rods 5 form an inverted U-shaped structure, and the traction frame 4 and the light rods 5 are mounted on the outer sides of the lower shell 1 and the upper shell 3.

[0032] It should be noted that in the initial state, the caster 2 inside the wheel groove 101 of the lower shell 1 is flush with the base 6 and both fit on the support surface of the support frame. When the automated terminal needs to be pushed or pulled, the traction frame 4 is held and pulled longitudinally, the reset spring 10 undergoes elastic deformation within the elastic limit, the light rod 5 slides relative to the guide seat 8, and the base 6 is separated from the support surface, and the lower shell 1 can be pushed and pulled horizontally.
