Description

Technical Field

[0001] The utility model relates to an electrical cabinet, in particular to an electrical cabinet with a double locking structure. Background Art

[0002] An electrical cabinet, also known as a distribution cabinet, is a box or cabinet structure used to install and protect electrical equipment. It is usually closed, made of metal, and placed in a power room within a building or industrial facility to centrally store electrical control equipment, power distribution equipment, automation equipment, and other related electronic and electrical equipment.

[0003] In order to ensure the safety of parts and electrical components in the electrical cabinet, it is common to add locks to the electrical cabinet. In the prior art, most electrical cabinets use a single locking structure to lock the cabinet door to prevent the cabinet door from opening, thereby protecting the equipment inside the electrical cabinet. However, a single locking mechanism is easily targeted for destruction. Because the single locking structure has only one layer of protection, there is a risk of being easily opened. Once the lock is cracked or damaged, the entire electrical cabinet will be exposed, and the internal equipment is vulnerable to damage or theft. Utility Model Content

The locking mechanism 3 includes a first locking component 31 and a second locking component 32, wherein the first locking component 31 is provided with two groups parallel to each other, and the second locking component 32 is provided between the two groups of the first locking components 31.

[0026] The first locking component 31 includes a double T-shaped limit frame 3101 installed transversely on the cabinet door 2, the limit frame 3101 is composed of a first limit rod 3108 and two first end heads 3109 parallel to each other, the contact surface between the limit frame 3101 and the cabinet door 2 is respectively provided with first slide grooves 3103 corresponding to the two first end heads 3109, and the first end heads 3109 and the first slide grooves 3103 constitute a sliding structure; a limit groove 3107 is provided at the edge of the first end head 3109 close to the second locking component 32; a first rack 3102 is installed on the other side of the limit frame 3101 away from the first slide groove 3103, the first rack 3102 is meshedly connected with the first gear 3106 below, the upper end surface of the first rack 3102 is provided with a first slide rod 3104, and the first slide rod 3104 is slidably connected with the first slide rail 3105.

[0027] The second locking assembly 32 includes a limit rod 3201 which is installed on the cabinet door 2 in a transverse direction. The limit rod 3201 and the cabinet door 2 form a sliding structure. A second rack 3202 is provided at one end of the limit rod 3201. A second gear 3209 is meshed and connected below the second rack 3202. A second slide rod 3203 is provided on the upper end surface of the second rack 3202. The second slide rod 3203 is slidably connected to a second slide rail 3204. The middle position of the limit rod 3201 is connected to two sets of The first connecting rod 3205, the other end of the first connecting rod 3205 is respectively connected to the second connecting rod 3206 through a rotating shaft and a bearing, the contact surface of the second connecting rod 3206 and the cabinet door 2 is provided with a second sliding groove 3208, and the end of the second connecting rod 3206 is provided with a limiting block 3207, the limiting block 3207 is adapted to the limiting groove 3107 provided at the first end 3109 close to the second locking component 32, so that the two groups of first locking components 31 respectively form a buckling structure with the second locking component 32. Therefore, only when the second locking component 32 is in an open state, can the first locking component 31 be opened, thereby unlocking the cabinet door 2.

[0028] A first rotating handle 4 connected to the first gear 3106 and a second rotating handle 5 connected to the second gear 3209 are respectively provided on the side of the cabinet door 2 away from the cabinet body 1. An electronic password lock protective cover 6 is installed around the first rotating handle 4 and the second rotating handle 5. Only authorized personnel can open the electronic password lock protective cover 6 and open the cabinet door 2 through the first rotating handle 4 and the second rotating handle 5 by entering the correct password or using an authorized identity authentication method. This can effectively prevent unauthorized personnel from illegally opening the cabinet door 2, thereby improving the safety of internal equipment.

[0029] like Figure 5 , 6As shown, the edge of the inner wall of the cabinet 1 is provided with a first locking groove 101 and a second locking groove 102, and the first locking groove 101 is adapted to the first end 3109 of the double T-shaped limiting frame 3101, and the second locking groove 102 is adapted to the limiting rod 3201. The second rotating handle 5 is rotated to rotate the second gear 3209 to drive the second rack 3202 and the second slide bar 3203 to move on the second slide rail 3204, thereby driving the limiting rod 3201 to move, so that the limiting rod 3201 is separated from the second locking groove 102, and at the same time, the first connecting rod 3205 and the second connecting rod 3206 drive the limiting block 3207 away from the limiting groove 3107, and at this time, the second locking assembly 32 is separated from the cabinet door 2 and the two sets of second locking assemblies 31 respectively. Then, the two groups of second locking components 31 are opened respectively, and the two first rotating handles 4 are rotated in turn, so that the first gear 3106 rotates to drive the first rack 3102 and the first slide bar 3104 to move on the first slide rail 3105, thereby driving the limit frame 3101 to move, and the two ends of the limit frame 3101 are separated from the first locking groove 101, finally separating the cabinet body 1 and the cabinet door 2.

[0030] Working principle: When using an electrical cabinet with a double locking structure, you first need to obtain the password through authorization and enter the correct secret to open each electronic password lock protective cover 6 before you can rotate the two first rotating handles 4 and the second rotating handle 5 to open the locking mechanism 3; when opening the locking mechanism 3, you need to first rotate the second rotating handle 5 to open the second locking component 32, and then you can rotate the two first rotating handles 4 in turn to open the two groups of first locking components 31.

[0031] When the second rotating handle 5 is rotated, the second gear 3209 rotates and drives the second rack 3202 and the second slide bar 3203 to move on the second slide rail 3204, thereby driving the limit rod 3201 to move, so that the limit rod 3201 is separated from the second locking groove 102, and at the same time, the first connecting rod 3205 and the second connecting rod 3206 drive the limit block 3207 away from the limit groove 3107. At this time, the second locking assembly 32 is separated from the cabinet door 2 and the two groups of second locking assemblies 31 respectively.

[0032] When the two first rotating handles 4 are rotated, the first gear 3106 rotates to drive the first rack 3102 and the first slide bar 3104 to move on the first slide rail 3105, thereby driving the limit frame 3101 to move, and the two ends of the limit frame 3101 are separated from the first locking groove 101, finally separating the cabinet body 1 and the cabinet door 2.
