[0021] Combination Figure 1-4 As shown, a withdrawable switch cabinet with a withdrawable limit function includes a switch cabinet body 1, and connecting plates 101 integrally formed therewith are symmetrically provided on both sides of the front end of the switch cabinet body 1, and a plurality of evenly distributed docking grooves 103 are provided on the inner end surface of the connecting plate 101. An accommodating cavity 102 is provided on the switch cabinet body 1 between the two connecting plates 101, and a plurality of drawers 2 are slidably connected in the accommodating cavity 102.

[0022] Among them, guide blocks 104 that match the guide groove 201 are provided on both inner walls of the accommodating cavity 102. Through the setting of the guide blocks 104 and the guide grooves 201, the stability of pulling out the drawer 2 is improved. Limiting grooves 105 that can allow the limiting blocks 202 to move are opened on the inner walls of the accommodating cavity 102 on the upper and lower sides of the guide blocks 104. Through the setting of the limiting grooves 105 and the limiting blocks 202, the displacement of the drawer 2 can be limited to prevent the drawer 2 from being pulled out of the accommodating cavity 102 and causing the drawer 2 to fall.

[0023] The switch cabinet body 1 is provided with a plurality of heat dissipation holes, thereby improving the heat dissipation effect of the switch cabinet body 1 .

[0024] Combination Figure 3-4The drawer 2 shown in the figure has a guide groove 201 with a trapezoidal structure on both the left and right outer walls of the drawer 2, and a limit block 202 with a T-shaped structure is provided on the outer end surface of the drawer 2 on the upper and lower sides of the guide groove 201, and support rods 203 are symmetrically provided on both sides of the top of the drawer 2, and one end of the support rod 203 is provided with a docking column 204 that can be inserted into the docking groove 103, and the other end of the support rod 203 is hingedly connected to a mounting column 205, and the mounting column 205 is rotatably connected to the drawer 2, so as to facilitate the staff to adjust the support rod 203 to insert the docking column 204 into the docking groove 103.

[0025] Wherein, buckles 206 capable of clamping and fixing the support rod 203 are provided on both side end surfaces of the top of the drawer 2. By setting the buckles 206, the support rod 203 in an unused state can be fixed.

[0026] like Figure 3 As shown, the support rod 203 is clamped in the buckle 206 when not in use, thereby preventing the support rod 203 from being displaced when the drawer 2 is pushed into the switch cabinet body 1, making it impossible for the drawer 2 to be reset, affecting the use effect.

[0027] like Figure 4 As shown, when the drawer 2 is pulled out to the outside of the switch cabinet body 1, the support rod 203 is disconnected from the buckle 206, and the docking column 204 on the support rod 203 is inserted into the docking groove 103 on the connecting plate 101, thereby improving the supporting force and bearing capacity of the drawer 2 pulled out to the outside of the switch cabinet body 1, and preventing one end of the drawer 2 from tilting downward.

[0028] The working principle of the utility model is:

[0029] When in use, the drawer 2 is pulled out of the accommodating chamber 102 through the groove (not marked) on the drawer 2. The guide block 104 in the accommodating chamber 102 is arranged with the guide groove 201 on the drawer 2, so that the displacement of the drawer 2 is more stable. At the same time, the limit block 202 on the drawer 2 is matched with the limit groove 105 provided on the inner side wall of the accommodating chamber 201, so that the displacement of the drawer 2 can be limited to prevent the drawer 2 from being pulled out of the accommodating chamber 102 and causing the drawer 2 to fall. When the drawer 2 is pulled out to the outside of the switch cabinet body 1, the support rod 203 is driven to disengage it from the connection with the buckle 206, and the support rod 203 is rotated to cooperate with the mounting column 205 so that the docking column 204 on the support rod 203 is plugged into the connecting column 206. The docking groove 103 on the connecting plate 101 improves the supporting force and bearing capacity of the drawer 2 pulled out to the outside of the accommodating cavity 102, and prevents one end of the drawer 2 from tilting downward. When the drawer 2 needs to be pushed into the accommodating cavity 102, the support rod 203 is driven to make the docking column 204 disengage from the connection with the docking groove 103, and the support rod 203 is snapped into the buckle 206, the support rod 203 is snapped and fixed, and then the drawer 2 is pushed to reset. The new type of use can maintain the connection relationship with the switch cabinet body 1 after the drawer 2 is pulled out, and prevents the drawer 2 from being disconnected from the switch cabinet body 1 during the pulling process, causing a safety hazard, and at the same time can support the drawer 2 pulled out of the switch cabinet body 1.
