Description

Technical Field

[0001] The utility model relates to the technical field of limiting devices, in particular to a door limiting device. Background Art

[0002] The distribution box is a widely used low-voltage power distribution product. When the distribution box is used, maintained and repaired, the door is often opened. In some special occasions and environments, the door is required to be restricted after opening and cannot be allowed to shake. Usually, a door limit device is set between the door and the box body.

[0003] After checking, the disclosure (announcement) number: CN209228225U discloses a door limit device. This technology discloses "comprising a fixed plate, a limit plate and a bent plate, wherein the limit plate is penetrated with a guide long groove along its length direction, and one end of the limit plate is penetrated with a U-shaped groove, wherein the U-shaped groove comprises a limit protrusion, a left accommodating groove and a right accommodating groove, wherein the limit protrusion is located between the left accommodating groove and the right accommodating groove, wherein the limit protrusion faces one end of the limit plate close to the U-shaped groove, wherein the left accommodating groove and the right accommodating groove are connected with one end of the guide long groove in sequence, and when the door panel is rotated to open, the door panel drives the limit plate to rotate around the fixing screw, and the convex shaft slides along the guide long groove toward the right accommodating groove, and when the convex shaft slides After moving to the right receiving groove, continue to rotate to open the door panel, the convex shaft is stuck in the left receiving groove through the limiting protrusion, and the left receiving groove and the limiting protrusion limit the convex shaft, and the door panel is limited to remain in the open state. Due to the limiting effect of the limiting protrusion, the door panel will not close suddenly; when closing the door panel, it is necessary to manually move the limiting plate to make the convex shaft disengage from the left receiving groove and slide into the right receiving groove through the limiting protrusion, and the limiting protrusion then slides along the guide long groove until the door panel is completely closed. The limiting structure is simple and reliable, and the operation is convenient. Due to the limiting effect of the limiting protrusion, the door panel will not close suddenly. When the door panel is opened, it has a locking function, which is very safe; the limiting device has a simple and ingenious structure, is easy to process and manufacture, is convenient to install, and has low cost.

[0004] However, the above-mentioned door limit device has the following disadvantages:
