[0002] An electrical cabinet door is a door panel installed on an electrical cabinet. It is mainly used to open and close the electrical cabinet, and plays a role in protecting electrical components and ensuring safe operation. Electrical cabinet doors usually have relevant indicators such as protection level. The materials can be metal, plastic or glass, etc. Different materials have their own characteristics and uses in different application scenarios.

[0003] In the prior art, patent publication number CN 118712008 B proposes an interlocking system for a grounding switch in an electrical cabinet. This system includes an electrical cabinet with a grounding switch inside. Ejection mechanisms are located on both sides of the grounding switch. A locking mechanism is fixedly connected to the inner surface of the cabinet door. The copper rod of the grounding switch is rotatably connected to the cabinet body. While the locking mechanism prevents direct contact between personnel and the cabinet body, improving operator safety, overall equipment reliability and lifespan, and enabling rapid door locking to save time and increase operational efficiency, the control buttons on the cabinet door surface are directly exposed during door opening, increasing the probability of collisions and potential safety accidents. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an electrical cabinet door device with a safety interlock mechanism. The safety baffle blocks the front end of the control switch the moment the electrical cabinet door is opened, which can reduce the probability of the control switch colliding with the outside and causing a safety accident, improve the safety of the electrical cabinet door, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical cabinet door device with a safety interlock mechanism, comprising an electrical cabinet door, wherein the front surface of the electrical cabinet door is provided with a display instrument mounting hole and a control switch mounting hole, the left side of the electrical cabinet door is provided with a connecting rotating plate, and further comprising a safety interlock mechanism;

[0006] The safety interlocking mechanism includes a slide, a slide plate, and a safety baffle. The slide is respectively set on the front surface of the electrical cabinet door. The slide is vertically slidably connected to the slide plate with elastic limit. A safety baffle is provided between the front ends of the two slide plates. The safety baffle is installed in conjunction with the control switch mounting hole. The slide plates are all connected to the electrical cabinet shaft for transmission.

[0007] Furthermore, the safety interlocking mechanism also includes a slider, an adjusting screw, a bevel gear ring, and a limiting plate. The bevel gear ring is located on the outer arc surface of the electrical cabinet shaft. The adjusting screw is rotatably connected to the rear side of the electrical cabinet door. A bevel gear is provided at the left end of the adjusting screw, and the bevel gear meshes with the bevel gear ring. Slider blocks are threaded to both ends of the outer arc surface of the adjusting screw. Limiting plates are provided on the upper surface of the sliders. The inclined surface of the limiting plate is fitted with the arc surface of the slider to drive the safety baffle to the electrical cabinet shaft.

[0008] Furthermore, the threads at the left and right ends of the adjusting screw are opposite, and the two limiting plates corresponding to the lateral position are symmetrical, so that the two limiting plates corresponding to the lateral position can move relative to each other.

[0009] Furthermore, the support plate surface on the rear side of the electrical cabinet door is provided with guide posts. The guide posts are vertically slidably connected to the guide holes on the surface of the sliding plate. The guide posts are located between two limiting plates corresponding to the front and rear positions, providing guiding support for the movement of the sliding plate.

[0010] Furthermore, the safety interlocking mechanism also includes springs, which are respectively disposed between the limiting plate at the lower end of the guide post and the lower surface of the slide plate. The springs are respectively movably sleeved on the outer arc surface of the guide post to provide elastic limiting for the slide plate.

[0011] Furthermore, the outer side of the slide is provided with a closed baffle. The front surface of the closed baffle is attached to the rear side of the electrical cabinet door. The closed baffle is installed in conjunction with the slide groove to seal the slide groove.

[0012] Furthermore, the rear side of the electrical cabinet door is provided with a protective shell, and the adjusting screw is rotatably connected between the left and right inner walls of the protective shell. The slider, the limiting plate and the sliding plate are all located inside the protective shell, thus concealing the interlocking components.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By connecting the safety baffle to the electrical cabinet's rotating shaft, the safety baffle blocks the front of the control switch the moment the electrical cabinet door is opened. Compared to the control switch being directly exposed during the opening of the electrical cabinet door, this reduces the probability of the control switch colliding with the outside and causing a safety accident, thus improving the safety of the electrical cabinet door.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: an electrical cabinet door device with a safety interlock mechanism, including an electrical cabinet door 1. The opening and closing of the electrical cabinet is controlled by rotating the electrical cabinet door 1. The front surface of the electrical cabinet door 1 is provided with display instrument mounting holes 2 and control switch mounting holes 3, providing space for the installation of electrical display instruments and electrical control switches. The left side of the electrical cabinet door 1 is provided with connecting rotating plates 4, providing support for the rotation connection of the electrical cabinet door 1.

[0022] The system also includes a safety interlock mechanism 5, which comprises a slide 51, a slide plate 52, and a safety baffle 53. The slide 51 is located on the front surface of the electrical cabinet door 1. Each slide 51 has a vertically sliding slide plate 52 with elastic limit. A safety baffle 53 is located between the front ends of the two slide plates 52. The safety baffle 53 is installed in conjunction with the control switch mounting hole 3. The slide plates 52 are connected to the rotating shaft of the electrical cabinet. The opening and closing of the electrical cabinet door 1 controls the up and down position of the safety baffle 53. When the electrical cabinet door 1 is closed, the safety baffle 53 is vertically misaligned with the control switch installed in the control switch mounting hole 3, which will not obstruct the operator's rapid operation of the control button. When the electrical cabinet door 1 is opened, the safety baffle 53 immediately resets. The safety baffle 53 blocks the front end of the control switch when the electrical cabinet door 1 is opened, reducing the probability of the control switch colliding with the outside and causing a safety accident.

[0023] The safety interlocking mechanism 5 includes a slider 54, an adjusting screw 55, a bevel gear 56, a bevel ring 57, and a limiting plate 58. The bevel ring 57 is located on the outer arc surface of the electrical cabinet shaft. The adjusting screw 55 is rotatably connected to the rear side of the electrical cabinet door 1. The left end of the adjusting screw 55 is provided with a bevel gear 56, which meshes with the bevel ring 57. The left and right ends of the outer arc surface of the adjusting screw 55 are threadedly connected to sliders 54. The upper surface of the slider 54 is provided with limiting plates 58. The inclined surface of the limiting plate 58 is fitted with the arc surface of the slide plate 52. The support plate surface on the rear side of the electrical cabinet door 1 is provided with a guide post 6. The guide post 6 is vertically slidably connected to the guide hole on the surface of the slide plate 52. The guide post 6 is located between the two limiting plates 58 corresponding to the front and rear positions, providing guidance and support for the sliding of the slide plate 52. The thread directions of the left and right ends of the adjusting screw 55 are opposite, and the two limiting plates 58 corresponding to the lateral positions are symmetrical, so that the two limiting plates 58 move in opposite directions.

[0024] The safety interlock mechanism 5 also includes springs 59, which are respectively located between the limiting plate at the lower end of the guide post 6 and the lower surface of the slide plate 52. The springs 59 are movably sleeved on the outer arc surface of the guide post 6 to provide elastic limiting for the slide plate 52. The middle of the outer side of the slide plate 52 is provided with a closed baffle 8. The front surface of the closed baffle 8 is in contact with the rear side of the electrical cabinet door 1. The closed baffle 8 is installed in conjunction with the slide groove 51. During the up and down movement of the slide plate 52, the closed baffle 8 always closes the rear end of the slide groove 51. The rear side of the electrical cabinet door 1 is provided with a protective shell 7. The adjusting screw 55 is rotatably connected between the left and right inner walls of the protective shell 7. The slider 54, the limiting plate 58 and the slide plate 52 are all located inside the protective shell 7 to hide the safety interlock components and provide support for the rotation of the adjusting screw 55.

[0025] The working principle of this utility model is as follows:

[0026] During use, when the electrical cabinet door is closed, the inclined surface of the limit plate 58 applies force to the arc surface of the slide plate 52, overcoming the elastic force of the spring 59, causing the slide plate 52 to move the safety baffle 53 downward. At this time, the safety baffle 53 is vertically misaligned with the control switch installed in the control switch mounting hole 3, which will not obstruct the operator's quick operation of the control button.

[0027] When the electrical cabinet door is opened, the bevel ring 57 is fixed in position with the electrical cabinet shaft. The rotation of the electrical cabinet door 1 will drive the bevel gear 56 to rotate around the bevel ring 57. Through the meshing connection between the bevel ring 57 and the bevel gear 56, the bevel gear 56 and the bevel ring 57 rotate relative to each other, driving the adjusting screw 55 to rotate. Through the threaded connection between the adjusting screw 55 and the slider 54, the two limit plates 58 corresponding to the lateral position are driven to move closer to each other due to the opposite direction of the threads at the left and right ends of the adjusting screw 55.

[0028] When the electrical cabinet door 1 rotates, the limit plate 58 immediately releases the limit on the slide plate 52. Under the elastic force of the spring 59, the safety baffle 53 moves upward and resets. The safety baffle 53 blocks the front end of the control switch when the electrical cabinet door 1 is opened, reducing the probability of the control switch colliding with the outside and causing a safety accident.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
