[0002] A firewall is a combination of a series of components set up between different networks (such as a trusted corporate intranet and an untrusted public network) or network security domains. It can monitor, restrict, and change data flows that cross the firewall, and shield the information, structure, and operating conditions inside the network from the outside as much as possible, thereby achieving network security protection. Firewall equipment has become an indispensable part of the network. The firewall is an advanced access control device. It is a combination of a series of components placed between different network security domains. It is the only channel for communication flows between different network security domains and can control access behavior in and out of the network according to the company's relevant security policies.

[0003] The existing stacking structure of firewall equipment is generally fixed on the outside of the protective wall equipment. Such a structural coordination leads to the need to remove the top firewall equipment in sequence when the lower firewall equipment needs to be repaired until the location of the firewall equipment that needs to be repaired is reached, resulting in complex maintenance operations for the bottom firewall equipment and inflexible structural coordination, which affects the effect of the stacking structure. In view of this, we propose a firewall device with a stacking structure. Utility Model Content

[0033] Working principle: During assembly, first place the firewall device body 1 inside the stacking assembly 2 so that the limit card strip 101 is combined with the limit card slot 207. The limit card slot 207 has no obstruction at the front end, so that the two can be connected. Then, the firewall device body 1 is moved to the inside of the stacking assembly 2 by pushing. In this way, the first convex strip 102 on the limit card strip 101 can be combined with the second convex strip 208 on the limit card slot 207. In this way, the firewall device body 1 can be limited so that it can only move in parallel. The moving distance of the firewall device body 1 can be limited under the limit of the baffle 209. After moving into place, the positioning member 3 can automatically align with the firewall The positioning groove 103 at the bottom of the firewall device body 1 is combined to limit the firewall device body 1 to achieve the effect of fixed assembly and ensure the stability of the combination of the two. Then, the support block 204 on the stacking component 2 is combined with the connecting groove 205 to stack them in sequence to achieve a stacking effect. Such a structural combination can be used to separate the positioning piece 3 from the positioning groove 103 when the bottom firewall device body 1 needs to be inspected, and then the firewall device body 1 can be pulled out for inspection. In this way, the overall position can be guaranteed to be stable under the support of the stacking component 2 itself, thereby eliminating the step of removing the firewall device body 1 in sequence, reducing the workload of inspection and facilitating use.
