Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box door limiting device. Background Technology

[0002] Currently, to facilitate the control and maintenance of electrical equipment, various switches and control devices are usually centrally installed in distribution boxes. During maintenance, most problems can be resolved simply by working within the distribution box, greatly simplifying the worker's operation. However, since distribution boxes often contain precision equipment such as switches and control devices, rainwater or dust entering can easily increase the probability of malfunctions. Therefore, distribution boxes are usually equipped with doors that can be opened and closed, allowing them to be opened for maintenance and kept closed at other times to protect the equipment inside. These doors are typically connected to the box body using hinges. However, since there is no limiting device, the door can easily be blown open by the wind after being opened, affecting the worker's maintenance operations. Therefore, a distribution box door limiting device is needed to limit the door's movement after it is opened, preventing it from interfering with the worker's maintenance operations and improving work efficiency and safety. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a power distribution box door limiting device. This device can limit the opening of the power distribution box door, preventing it from interfering with workers' maintenance operations and improving work efficiency and safety.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a limiting device for a distribution box door, comprising: a box body, a box door, a fixed shaft, a limiting rod, and a limiting shaft. One side of the box door is connected to the box body via a hinge. The fixed shaft is fixedly installed on the inner wall of the box body near the hinge side. The limiting shaft is fixedly installed on the inner side of the box door, and the fixed shaft and the limiting shaft are on the same horizontal plane. One end of the limiting rod is rotatably mounted on the fixed shaft, and the lower part of the other end of the limiting rod is provided with a notch. The limiting shaft is provided with a connecting groove, and the limiting rod is engaged with the connecting groove of the limiting shaft through the notch.

[0006] Furthermore, the box body has a flange on the opening side, and a baffle is fixedly installed on the flange. The baffle and the box body form a limiting groove with the opening facing upward.

[0007] Furthermore, when the end of the limiting rod is engaged with the limiting shaft, the middle part of the limiting rod is connected to the housing through the limiting groove.

[0008] Furthermore, there are 1 to 3 sets of the fixed shaft, the limiting rod, the limiting shaft, and the baffle.

[0009] Furthermore, the fixed shaft is provided with vertically symmetrical stops, and the connection between the limiting rod and the fixed shaft is provided with a groove corresponding to the shape of the stops.

[0010] Furthermore, the grooves are distributed on both sides of the through hole of the limiting rod along the length of the limiting rod.

[0011] The beneficial effects of this utility model are as follows: By setting a rotatable limiting rod inside the box, the limiting rod can limit the box door after it is opened, preventing the box door from closing due to factors such as wind, avoiding the box door from affecting the worker's maintenance operation, improving work efficiency and safety. When not in use, the limiting rod can be rotated to a vertical state to avoid the limiting rod affecting the closing of the box door. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0018] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of this utility model provides a distribution box door limiting device, including: a box body 1, a box door 2, a fixed shaft 3, a limiting rod 4, and a limiting shaft 5. One side of the box door 2 is connected to the box body 1 via a hinge. The fixed shaft 3 is fixedly installed on the inner wall of the box body 1 near the hinge side. The limiting shaft 5 is fixedly installed on the inner side of the box door 2, and the fixed shaft 3 and the limiting shaft 5 are on the same horizontal plane. One end of the limiting rod 4 is rotatably installed on the fixed shaft 3, and the other end of the limiting rod 4 has a notch 6 at its lower part. The limiting shaft 5 has a connecting groove 7, and the limiting rod 4 is engaged with the connecting groove 7 of the limiting shaft 5 through the notch 6.

[0020] After the door 2 is opened, the worker can rotate the limiting rod 4 so that the end of the limiting rod 4 with the notch 6 faces upward. Then, the groove on the limiting rod 4 passes through the stop 9 and slides to the left side of the fixed shaft 3. At this time, the limiting rod 4 and the limiting groove are on the same plane. After rotating the limiting rod 4 downward, the notch 6 on the limiting rod 4 hooks into the connecting groove 7 on the limiting shaft 5. At the same time, the middle part of the limiting rod 4 enters the limiting groove. At this time, the door 2 is connected to the box body 1 through the limiting rod 4. The door 2 remains open and will not be closed by factors such as wind, thus avoiding the door 2 affecting the worker's maintenance operation and improving work efficiency and safety. When the limiting rod 4 is not in use, it can be rotated upward so that the groove on the limiting rod 4 passes through the stop 9 and moves to the right side of the fixed shaft 3. At this time, the limiting rod 4 can rotate on the fixed shaft 3 without being blocked by the stop 8, thus allowing the limiting rod 4 to rotate from vertically upward to vertically downward, reducing the space occupied by the limiting rod 4. At this time, the door 2 can be closed freely.

[0021] In a preferred embodiment, the opening side of the box body 1 is provided with a flange, and a baffle 8 is fixedly installed on the flange. The baffle 8 and the box body 1 form an upward-facing limiting groove. The baffle 8 can increase the stability of the limiting rod 4 when it is limited and reduce the swing amplitude of the box door 2 after it is limited.

[0022] In a specific embodiment, Figure 1 , Figure 2As shown, when the end of the limiting rod 4 is engaged with the limiting shaft 5, the middle part of the limiting rod 4 is connected to the box body 1 through the limiting groove. The baffle 8 can increase the stability of the limiting rod 4 when it is limited and reduce the swing amplitude of the box door 2 after it is limited.

[0023] Preferably, there are 1 to 3 sets of fixed shaft 3, limiting rod 4, limiting shaft 5, and baffle 8. The multiple sets of limiting devices of the copper drum can improve the limiting effect of the box door 2 and improve the stability of the box door 2 after it is limited.

[0024] In a preferred embodiment, such as Figure 3 As shown, the fixed shaft 3 is vertically and symmetrically provided with stop blocks 9. The connection between the limiting rod 4 and the fixed shaft 3 is provided with a groove corresponding to the shape of the stop block 9. When the limiting rod 4 is in the limiting position, the groove on the limiting rod 4 is misaligned with the stop block 9, so that the end of the limiting rod 4 can be limited by the stop block 9, so that the limiting rod 4 cannot move axially on the fixed shaft 3, thereby improving the stability of the limiting rod 4.

[0025] Specifically, the grooves are distributed on both sides of the through hole of the limiting rod 4 along the length of the limiting rod 4, so that when the limiting rod 4 is vertically upward or downward, the grooves on the limiting rod 4 are flush with the stop block 9, so that the grooves pass through the stop block 9, which makes it easier for the limiting rod 4 to overcome the obstruction of the baffle 8 and rotate in the door 2, thereby reducing the space occupied by the limiting rod 4 and making it easier to close the door 2 after storing the limiting rod 4.

[0026] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
