Specific embodiments

[0021] As Figure 1 、 2 shown, a safety structure of an emergency power supply quick access cabinet includes a low-voltage cabinet 10, and a quick access device 11 is arranged at the front end inside the low-voltage cabinet 10; a cabinet door 12 is installed on the front of the low-voltage cabinet 10, and a protection mechanism 20 is arranged on the front of the cabinet door 12.

[0022] When there is a power outage outside, the plug can be electrically connected to the socket on the quick access device 11, so as to achieve the effect of supplying emergency power to the outside.

[0023] Refer to Figure 2 、 3 、4, the protection mechanism 20 includes a protection frame 201 fixedly connected to the front of the cabinet door 12, the surface of the cabinet door 12 is open at the connection with the protection frame 201, a sliding groove 202 is opened inside the protection frame 201, and a movable L-shaped plate 203 is slidably connected inside the sliding groove 202.

[0024] Preferably, a pair of limiting grooves 204 are formed on the right side of the sliding groove 202. A sliding block 205 is slidably connected inside the limiting groove 204. The left sides of the pair of sliding blocks 205 are fixedly connected to the L-shaped plate 203. When the L-shaped plate 203 moves up and down, the sliding block 205 is driven to slide along the surface of the limiting groove 204, so as to achieve the effect of guiding the movement of the L-shaped plate 203 and limit the moving distance of the L-shaped plate 203, preventing the L-shaped plate 203 from detaching from the protective frame 201.

[0025] Specifically, the L-shaped plate 203 includes a vertical plate and a horizontal plate. The vertical plate is perpendicularly connected to the bottom edge of the horizontal plate. A pair of insertion blocks 206 are fixedly connected to the top of the horizontal plate. A positioning groove 207 is formed on the left side of the insertion block 206. Docking grooves 208 are respectively formed at the bottom parts of the front and rear sides of the protective frame 201. An activity groove 209 is formed on the left side of the docking groove 208. A support spring 211 is fixedly connected to the left side inside the activity groove 209. The right side of the support spring 211 is fixedly connected to a positioning block 210.

[0026] Preferably, the right side surface of the positioning block 210 is an arc gradually becoming longer from bottom to top. When it is necessary to protect the quick access device 11, the L-shaped plate 203 is pulled upward. The L-shaped plate 203 slides inside the sliding groove 202 until the L-shaped plate 203 is completely merged with the protective frame 201, thus forming a complete whole to protect the quick access device 11. When the L-shaped plate 203 moves upward, the insertion block 206 is inserted into the docking groove 208 and contacts the surface of the positioning block 210. The contact force makes the positioning block 210 move leftward and compresses the support spring 211 at the same time until the positioning groove 207 corresponds to the position of the positioning block 210. Then the support spring 211 drives the positioning block 210 to rebound and insert into the positioning groove 207, so as to achieve the fixing effect after the L-shaped plate 203 is merged with the protective frame 201.

[0027] Preferably, a guiding groove 212 is formed on the left side of the positioning block 210. A guiding rod 213 is slidably connected inside the guiding groove 212. The left side of the guiding rod 213 is fixedly connected to the side wall of the activity groove 209. When the positioning block 210 moves, the activity groove 209 is driven to slide along the surface of the guiding rod 213, so as to achieve the effect of guiding the movement of the positioning block 210.

[0028] Further, a through groove 214 is formed in the front surface of the protection frame 201. The through groove 214 communicates with the movable groove 209. A pull handle 215 is slidably connected inside the through groove 214. The rear side of the pull handle 215 is fixedly connected to a positioning block 210. When the quick access device 11 needs to be used, pull the two pull handles 215 to the left. The pull handle 215 drives the positioning block 210 to move leftward out of the positioning groove 207. Thus, the L-shaped plate 203 loses its restriction and moves downward under gravity, exposing the quick access device 11. Usually, the quick access device 11 is exposed outside or installed inside the cabinet body. When the quick access device 11 is completely exposed outside, sediment from the outside easily enters its interface and it is easily impacted by foreign objects, resulting in unstable connection during use. When the quick access device 11 is installed inside the cabinet body, the installation door needs to be opened for use, but the installation door is usually locked. Therefore, it is difficult to quickly use the quick access device 11. However, the above device can effectively protect the quick access device 11 when it is not in use by setting a protection mechanism 20 on the cabinet door 12. When the quick access device 11 is in use, the quick access device 11 can be quickly and conveniently exposed, perfectly solving the above problems. And because the protection mechanism 20 is convenient to open, it further achieves the effect of quickly electrically connecting the external plug to the quick access device 11.

[0029] Reference Figure 1 、 5 On the bottom of the left and right sides of the low-voltage cabinet 10, a heat dissipation mechanism 30 is provided. The heat dissipation mechanism 30 includes heat dissipation grooves 301 formed on the left and right sides of the low-voltage cabinet 10. A dust-proof net 302 is fixedly connected to the outside of the heat dissipation grooves 301. A waterproof breathable film 303 is arranged inside the heat dissipation grooves 301. A fan 305 is fixedly installed on one side of the low-voltage cabinet 10 close to the waterproof breathable film 303 through a mounting bracket 304.

[0030] When the components inside the low-voltage cabinet 10 are in use, a large amount of heat is generated. In order to keep the temperature inside the low-voltage cabinet 10 appropriate and discharge the heat, the heat dissipation mechanism 30 is designed. During use, the fan 305 is started through an external power supply. The input end of the fan 305 sucks in the hot air inside the low-voltage cabinet 10, and then discharges the hot air through the waterproof breathable film 303 and the dust-proof net 302. The dust-proof net 302 has a relatively hard material, which can prevent dust from entering the low-voltage cabinet 10 while being resistant to collision. The waterproof breathable film 303 can prevent rain or splashing water from entering the inside of the low-voltage cabinet 10.

[0031] The working principle of the present utility model is as follows: When it is necessary to protect the quick access device 11, the L-shaped plate 203 is pulled upward, and the L-shaped plate 203 slides inside the sliding groove 202 until the L-shaped plate 203 is completely merged with the protection frame 201, thereby forming a complete whole to protect the quick access device 11. During the upward movement of the L-shaped plate 203, the insertion block 206 inserts into the docking groove 208 and contacts the surface of the positioning block 210. The contact force causes the positioning block 210 to move leftward and compresses the support spring 211 at the same time until the positioning groove 207 corresponds to the position of the positioning block 210. Thus, the support spring 211 drives the positioning block 210 to rebound and insert into the positioning groove 207, thereby achieving the fixing effect after the L-shaped plate 203 is merged with the protection frame 201.

[0032] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
