Description

Technical Field

[0001] This invention relates to the field of distribution cabinet technology, and more specifically, to a distribution cabinet for electrical equipment with child-proof features. Background Technology

[0002] Distribution cabinets, also known as distribution boxes, are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are suitable for situations where the load is relatively dispersed and there are few circuits; motor control centers are used for situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Existing outdoor distribution cabinets have a low safety protection factor, and the cabinet doors are easy to open, making it easy for children to accidentally open the cabinet doors and get electric shocks, posing a certain safety hazard. Furthermore, if a locking device is added, the ease of operation during maintenance must also be considered. Therefore, a distribution cabinet for electrical equipment with child-proof opening function is proposed to solve the above problems. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a power distribution cabinet for electrical equipment with the effect of preventing children from accidentally opening it.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] An electrical equipment distribution cabinet with child-proof opening function includes a cabinet body, a cabinet door on the front of the cabinet body, a lockable switch handle on the cabinet door, and an I-shaped protective frame on the outside of the cabinet body, the I-shaped protective frame being located at a high position of the cabinet body and covering the cabinet door.

[0007] The I-shaped protective frame includes two rotating blocks, an I-beam frame, and two springs. The two rotating blocks are rotatably connected to the two sides of the cabinet on opposite sides. The two ends of the I-beam frame are respectively connected to the interior of the rotating blocks through and with damping sliding, and the ends of the I-beam frame are elastically connected to the interior of the rotating blocks through springs.

[0008] One inclined surface of the triangular pad is set at a 45-degree angle forward and upward. When the I-beam is rotated upward by a 45-degree angle by the rotating block, its rear side is in contact with the inclined surface of the triangular pad.

[0009] The top of the I-beam frame is equipped with a handle.

[0010] The front of the cabinet is rotatably connected to two T-shaped limiting rods, and the interior of the I-beam frame has two through slots for the T-shaped limiting rods to pass through.

[0011] The front of the I-beam frame is provided with a circular groove that communicates with the through groove, and the end of the T-shaped limiting rod is rotatable inside the circular groove.

[0012] The inner side of the I-beam frame is equipped with a rubber pad;

[0013] The top of the cabinet is provided with a triangular pad, one of the inclined surfaces of which faces forward and cooperates with the I-shaped protective frame.

[0014] As a further description of the above technical solution: the inner side of the I-beam frame is provided with a rubber pad.

[0015] Compared with the prior art, the advantages of this invention are:

[0016] (1) This solution uses a high-positioned I-shaped protective frame to cover the cabinet door handle. It takes advantage of the fact that children are too short to lift and turn the handle, thus preventing children from accidentally opening the door. At the same time, it does not affect the normal opening operation of adults. No additional key is required, which improves the convenience of maintenance operation. The I-shaped protective frame can be rotated upwards and retracted. When it is necessary to operate the switch handle, adults can press and pull the I-shaped frame to make the I-shaped frame slide along the rotating block to compress the spring. After the I-shaped frame is removed from the limit of the T-shaped limit rod, the I-shaped protective frame can be flipped upwards. After flipping, the rear side of the I-shaped frame is supported and positioned by the inclined surface of the triangular pad, which can keep it open and will not affect the normal opening and closing operation of the cabinet door.

[0017] (2) This solution can be used to push the I-beam frame to reset by rotating it downwards and then using the spring force to rotate it. The T-shaped limit rod can be rotated to lock the I-beam frame and keep the switch handle covered. The double protection effectively prevents children from accidentally touching and opening the switch, improves the safety of the power distribution cabinet, and the opening and closing operation is very convenient.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] To address the safety hazard posed by children accidentally opening cabinet doors and risking electric shock due to the ease with which the cabinet doors can be opened, Implementation Example 1 is proposed:

[0026] Please see Figures 1-4 In this invention, an electrical distribution cabinet for electrical equipment with child-proof operation includes a cabinet body 1. The front of the cabinet body 1 has a cabinet door 2, and the cabinet door 2 has a lockable switch handle 3. An I-shaped protective frame 4 is located on the outer side of the cabinet body 1, positioned at a high position and obstructing the cabinet door 2. A triangular pad 5 is located on the top of the cabinet body 1, with one inclined surface of the triangular pad 5 facing forward and engaging with the I-shaped protective frame 4.

[0027] The I-shaped protective frame 4 includes two rotating blocks 41, an I-beam frame 42, and two springs 43. The two rotating blocks 41 are rotatably connected to the two sides of the cabinet 1 on opposite sides. The top of the I-beam frame 42 is provided with a handle 421. The two ends of the I-beam frame 42 are respectively connected to the interior of the rotating blocks 41 through and with damping sliding, and the ends of the I-beam frame 42 are elastically connected to the interior of the rotating blocks 41 through the springs 43.

[0028] One inclined surface of the triangular pad 5 is set at a 45-degree angle forward and upward. When the I-beam 42 is rotated upward by 45 degrees by the rotating block 41, its rear side is in contact with the inclined surface of the triangular pad 5.

[0029] In this invention, a high-positioned I-shaped protective frame 4 is used to cover the lockable switch handle 3. Children, due to their height limitations, cannot easily reach or operate the I-shaped protective frame 4 to open the cover. When an adult needs to open the cabinet door 2, they can raise their hand to grasp the handle bar 421 and pull the I-shaped frame 42 in a straight line, causing the tension spring 43 to separate the I-shaped frame 42 from the switch handle 3. Then, the I-shaped frame 42 is rotated upwards. After rotating forty-five degrees, the side of the I-shaped frame 42 fits against the inclined surface of the triangular pad 5, achieving a stable overlap and preventing it from falling freely. At this point, the cabinet door 2 can be opened through the switch handle 3. The operation is simple and quick and will not obstruct normal maintenance work. Children are too short to reach the high-positioned handle bar 421 to pull and rotate the I-shaped protective frame 4, nor can they touch the covered switch handle 3, thus effectively preventing children from accidentally opening the distribution cabinet and causing electric shock accidents, and improving the safety of the distribution cabinet.

[0030] Furthermore, considering the ease of operation during maintenance as in Embodiment 1, Embodiment 2 is proposed:

[0031] Please see Figure 3 and 4 The cabinet 1 has two T-shaped limiting rods 6 rotatably connected to its front side. The I-beam frame 42 has two through slots 7 for the T-shaped limiting rods 6 to pass through. The front side of the I-beam frame 42 has a circular slot 8 that communicates with the through slots 7. The ends of the T-shaped limiting rods 6 can rotate inside the circular slot 8.

[0032] The inner side of the I-beam frame 42 is provided with a rubber pad 422.

[0033] In this invention, by passing the T-shaped limiting rod 6 through the through groove 7 and rotating it 90 degrees, the end of the T-shaped limiting rod 6 can be engaged with the inner wall of the circular groove 8 to lock the position of the I-beam frame 42. When shielding is needed, the structural stability is further improved, and the possibility of shaking and accidental opening is reduced. When the shielding needs to be opened for operation, simply rotating the T-shaped limiting rod 6 can release the lock, making the operation convenient. At the same time, a rubber pad 422 is provided to buffer the impact when the I-beam protective frame 4 is reset to shield, reducing structural wear and noise.

[0034] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
