DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-5 The utility model provides a technical solution: an electric energy metering box with a pull-out structure, comprising a cabinet 1 and a push-pull mechanism 2, a push-pull mechanism 2 is arranged on one side of the surface of the cabinet 1, and a heat dissipation mechanism 3 is arranged at one end of the cabinet 1;

[0020] The push-pull mechanism 2 includes a first rolling groove 201, a second rolling groove 202, a connecting block 203, a first rotating shaft 204, a push-pull plate 205, a roller 206, a second rotating shaft 207, a locking block 208, a rotating door 209, a push-pull groove 210, a rotating groove 211 and a handle 212. The first rolling groove 201 is opened on one side of the surface of the cabinet 1, the second rolling groove 202 is opened on one side of the surface of the cabinet 1, the connecting block 203 is fixedly connected to the surface of the cabinet 1, and the first The cabinet 1 has a rotating shaft 204, a push-pull plate 205 attached to the inside, a roller 206 embedded in the first rolling groove 201, a second rotating shaft 207 embedded in the second rolling groove 202, a clamping block 208 connected to one end of the connecting block 203, a rotating door 209 connected to one side of the surface of the first rotating shaft 204, a push-pull groove 210 opened at one end of the push-pull plate 205, a rotating groove 211 opened at one end of the push-pull plate 205, a handle 212 fixedly connected to one side of the rotating door 209, and a rotating door 209 connected to the rotating door 209. Through the arrangement of the first rolling groove 201, the second rolling groove 202, the connecting block 203, the first rotating shaft 204, the push-pull plate 205, the roller 206, the second rotating shaft 207, the engaging block 208, the rotating door 209, the push-pull groove 210, the rotating groove 211 and the handle 212, when the pull-out structure is needed, the engaging block 208 is rotated, and when one end of the engaging block 208 completely leaves the rotating door 209, the handle 212 is pulled, and the handle 212 makes a pair of rotating doors 209 open. After 209 is opened and closed, the push-pull groove 210 is pulled to move the push-pull plate 205 to the outside of the cabinet 1. The push-pull plate 205 causes the second rotating shaft 207 inside the rotating groove 211 to rotate, and the second rotating shaft 207 drives the rollers 206 fixedly connected at both ends thereof to rotate in the first rolling groove 201. When the second rotating shaft 207 rotates to the end of the second rolling groove 202, the push-pull plate 205 is pulled out, and then the above process is reversed to achieve the pulling and pulling effect, thereby facilitating the inspection and maintenance of the electric energy meter box.

[0021] Furthermore, the second rotating shaft 207 is embedded in the rotating groove 211, and the rollers 206 are fixedly connected to both ends of the second rotating shaft 207. Through the setting of the second rotating shaft 207, the second rotating shaft 207 connects the push-pull plate 205 with the roller 206, so that the push-pull plate 205 is moved out of the cabinet body 1 by the rolling of the roller 206 in the first rolling groove 201, thereby ensuring the normal operation of the push-pull mechanism 2.

[0022] Furthermore, the rotating door 209 forms a mutually rotating structure with the cabinet 1 through the first rotating shaft 204, and the locking block 208 forms a mutually rotating structure with the cabinet 1 through the connecting block 203. One side of the locking block 208 is in contact with the rotating door 209. Through the setting of the locking block 208, when the cabinet 1 is closed, one side of the locking block 208 is in contact with the rotating door 209, thereby limiting the rotating door 209 on one side of the cabinet 1, thereby avoiding the circuit components on the push-pull plate 205 from being exposed due to the opening of the rotating door 209, causing unnecessary losses.

[0023] Further, the heat dissipation mechanism 3 includes a first vent 301, a heat dissipation component 302, a mounting groove 303, a second vent 304, a filter frame 305 and a filter screen 306. The first vent 301 is provided on one side of the surface of the cabinet 1, the heat dissipation component 302 is installed at one end of the cabinet 1, the mounting groove 303 is provided at one end of the cabinet 1, the second vent 304 is provided at one end of the push-pull plate 205, the filter frame 305 is embedded in the mounting groove 303, and the filter screen 306 is installed in the filter frame 305. Through the first vent 301, the heat dissipation component 302, the mounting groove 303, the second vent 304, the filter screen 306 The setting of the filter frame 305 and the filter screen 306 will generate heat when the cabinet 1 is running for a long time. At this time, the heat dissipation component 302 is turned on. The activation of the heat dissipation component 302 allows the hot air in the cabinet 1 to be discharged from the cabinet 1 through the first vent 301. At the same time, hot air from different layers can pass through the second vent 304 on the push-pull plate 205, and then the layers where the heat dissipation mechanism 3 is located, and finally be discharged through the heat dissipation component 302 and the first vent 301. At the same time, the filtering structure inside the installation groove 303 can filter out the dust in the cabinet 1. Through regular cleaning and replacement, the purpose of extending the service life of the heat dissipation mechanism 3 is achieved.

[0024] Furthermore, one end of the heat dissipation component 302 is arranged inside the first air vent 301, and the positions of the first air vent 301 and the filter frame 305 are relatively aligned. Through the setting of the heat dissipation component 302, the heat dissipation component 302 and the first air vent 301 are staggered and installed, which can increase the heat dissipation efficiency of the first air vent 301. When the heat inside the cabinet 1 is high, the first air vent 301 can quickly discharge the hot air out of the cabinet 1, thereby protecting the circuit components inside the cabinet 1.

[0025] Working principle: when the pull-out structure is needed, rotate the engaging block 208. When one end of the engaging block 208 completely leaves the rotating door 209, pull the handle 212. The handle 212 causes a pair of rotating doors 209 to be pulled open. When the rotating door 209 is opened and closed, pull the push-pull groove 210 to move the push-pull plate 205 to the outside of the cabinet 1. The push-pull plate 205 causes the second rotating shaft 207 inside the rotating groove 211 to rotate. The second rotating shaft 207 drives the rollers 206 fixedly connected at both ends thereof to rotate in the first rolling groove 201. When the second rotating shaft 207 rotates to the end of the second rolling groove 202, the push-pull plate 205 is pulled out. Then the above process is reversed to achieve the pulling effect, thereby making it possible to pull the push-pull plate 205 to the outside of the cabinet 1. During the inspection and maintenance of the electric energy meter box, heat will be generated during the long-term operation of the cabinet 1. At this time, the heat dissipation component 302 is turned on. The activation of the heat dissipation component 302 allows the hot air in the cabinet 1 to be discharged from the cabinet 1 through the first vent 301. At the same time, hot air from different layers can pass through the second vent 304 on the push-pull plate 205, and then the layers where the heat dissipation mechanism 3 is located, and finally discharged through the heat dissipation component 302 and the first vent 301. At the same time, the filtering structure inside the mounting groove 303 can filter out the dust in the cabinet 1. Through regular cleaning and replacement, the service life of the heat dissipation mechanism 3 can be extended, thereby better dissipating the heat. In this way, an electric energy meter box with a pull-out structure is completed.
