Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to an anti-misoperation interlocking mechanism for a mechanism box. Background Technology

[0002] A housing is an enclosed structure used to house and protect mechanical, electrical, or electronic equipment. It is widely used in industrial automation, power systems, traffic control, and many other fields. It not only provides physical protection for internal components against dust, moisture, and external impacts, but also integrates functions such as heat dissipation and ventilation to ensure stable operation of equipment under various environmental conditions.

[0003] Currently, existing interlocking mechanisms mostly rely on mechanical linkage, which is simple in structure and depends on the mechanical linkage of the circuit breaker main shaft drive shaft. However, long-term use can easily lead to component wear or jamming, resulting in interlocking failure and equipment malfunction. Furthermore, existing interlocking mechanisms lack measures to prevent misoperation, which can cause equipment damage if workers make operational errors during inspection or maintenance.

[0004] Therefore, it is necessary to design an interlocking mechanism to prevent misoperation of the mechanism box. Utility Model Content

[0005] In order to overcome the shortcomings of existing interlocking mechanisms, which rely heavily on mechanical linkage, have simple structures, and lack measures to prevent misoperation, resulting in equipment damage if workers make operational errors during inspection or maintenance, the technical problem to be solved by this utility model is to provide an anti-misoperation interlocking mechanism for mechanism boxes.

[0006] The technical implementation scheme of this utility model is as follows: a mechanism box anti-misoperation interlocking mechanism, including a mounting frame, a guide rod, a sliding frame, a pressing component, a spring, a moving contact, a stationary contact, a control panel connector, a linkage mechanism, and a prevention mechanism. The control panel connector is provided at the bottom of the mounting frame. The guide rod is slidably connected to the mounting frame, and the sliding frame is slidably connected to the guide rod. The spring is provided on the guide rod, and both ends of the spring are respectively connected to one end of the sliding frame and one end of the guide rod. The pressing component is slidably connected to the mounting frame near the sliding frame. The linkage mechanism is provided on the mounting frame. One end of the linkage mechanism is connected to the guide rod, and the other end is connected to the moving contact. A stationary contact is provided on the side of the mounting frame corresponding to the moving contact. The prevention mechanism includes a sliding rod and a guide plate. The guide plate is fixedly connected to the mounting frame, and the guide plate and the linkage mechanism are slidably connected to the sliding rod.

[0007] More preferably, the guide plate has sliding holes, which are multi-folded, allowing the slide rod to slide within the sliding holes.

[0008] More preferably, a threaded rod is rotatably connected to one side of the mounting frame, and a sliding member is threaded onto the threaded rod. One end of the sliding member passes through the mounting frame and is connected to the stationary contact.

[0009] More preferably, the linkage mechanism includes a connecting frame, a crossbar, a guide frame, and a square tube. The connecting frame is rotatably connected to the mounting frame. One end of the connecting frame is rotatably connected to the crossbar, which is fixedly connected to the guide rod. The other end of the connecting frame is rotatably connected to the square tube, which is connected to the moving contact. The guide frame is fixedly connected to the mounting frame near the square tube, and the guide frame is slidably connected to the square tube.

[0010] More preferably, the sliding frame has an inclined surface on the side facing the extruder, and one end of the extruder contacts the inclined surface of the sliding frame.

[0011] More preferably, a slide rail is fixedly connected to one side of the mounting frame, and the moving contact slides in contact with the slide rail.

[0012] Compared with the prior art, the present invention has the following advantages: By setting a sliding rod and a guide plate, during maintenance and repair, the sliding rod can be slid to the upper end of the sliding hole of the guide plate and then released, which can fix the square cylinder to separate the moving contact from the stationary contact, so that the circuit is always disconnected, preventing line and equipment failure caused by incorrect operation. At this time, the linkage of the device fails, further ensuring safety. Attached Figure Description

Detailed Implementation

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example: A mechanism box for preventing misoperation interlocking, such as... Figures 1-5 As shown, the system includes a mounting frame 1, a guide rod 2, a sliding frame 3, an extrusion member 31, a spring 4, a moving contact 72, a stationary contact 9, a control panel connector 10, a linkage mechanism, and a prevention mechanism. The control panel connector 10 is located at the bottom of the mounting frame 1. The guide rod 2 is slidably connected to the mounting frame 1, and the sliding frame 3 is slidably connected to the guide rod 2. The spring 4 is located on the guide rod 2, and its two ends are respectively connected to one end of the sliding frame 3 and one end of the guide rod 2. The extrusion member 31 is slidably connected to the mounting frame 1 near the sliding frame 3. The linkage mechanism is located on the mounting frame 1, with one end connected to the guide rod 2 and the other end connected to the moving contact 72. The stationary contact 9 is located on one side of the mounting frame 1 corresponding to the moving contact 72. The prevention mechanism includes a slide rod 11 and a guide plate 12. The guide plate 12 is fixedly connected to the mounting frame 1, and the slide rod 11 is slidably connected to the guide plate 12 and the linkage mechanism.

[0021] like Figures 2-4 As shown, the sliding frame 3 has an inclined surface on the side facing the extruder 31. One end of the extruder 31 contacts the inclined surface of the sliding frame 3. A sliding hole is provided on the guide plate 12. The sliding hole on the guide plate 12 has a multi-fold structure. The sliding rod 11 can slide in the sliding hole of the guide plate 12. Here, the sliding rod 11 is slid, so that the sliding rod 11 moves to the upper end of the sliding hole of the guide plate 12. Then the sliding rod 11 is released, and the sliding rod 11 drives the connected square cylinder 71 to move upward and be limited and fixed, so that the moving contact 72 is separated from the stationary contact 9. At this point, the circuit inside the mechanism box is always in a disconnected state. Similarly, when the sliding rod 11 moves to the lower end of the sliding hole of the guide plate 12, the circuit inside the mechanism box is always in a connected state.

[0022] like Figure 5 As shown, a threaded rod 13 is rotatably connected to one side of the mounting frame 1. A sliding member 14 is threaded onto the threaded rod 13. One end of the sliding member 14 passes through the mounting frame 1 and is connected to the stationary contact 9. Here, when the threaded rod 13 is turned, the threaded rod 13 drives the sliding member 14 to move during rotation. The sliding member 14 drives the stationary contact 9 to move in a direction away from the moving contact 72. This keeps the circuit inside the mechanism box always disconnected, enabling emergency prevention after operational errors and further improving operational safety.

[0023] like Figures 2-3As shown, the linkage mechanism includes a connecting frame 5, a crossbar 6, a guide frame 7, and a square tube 71. The connecting frame 5 is rotatably connected to the mounting frame 1. One end of the connecting frame 5 is rotatably connected to the crossbar 6, which is fixedly connected to the guide rod 2. The other end of the connecting frame 5 is rotatably connected to the square tube 71, which is connected to the moving contact 72. The guide frame 7 is fixedly connected to the mounting frame 1 near the square tube 71. The guide frame 7 is slidably connected to the square tube 71. When the crossbar 6 moves upward, it drives the connecting frame 5 to rotate, thereby causing the square tube 71 to move with the connecting frame 5. Under the guidance of the guide frame 7, the square tube 71 moves downward.

[0024] like Figure 3 As shown, a slide rail 8 is fixedly connected to one side of the mounting frame 1. The moving contact 72 is slidably connected to the slide rail 8. Here, the design of the slide rail 8 can effectively ensure the stability of the movement of the moving contact 72, so that it can slide down accurately to the stationary contact 9, prevent the moving contact 72 from deviating, and ensure the stable operation of the device.

[0025] This device is installed inside the mechanism housing to control the connection or disconnection of the internal circuitry. During normal use, closing the housing door applies pressure to the pressing component 31, causing it to slide inwards towards the mounting frame 1. This sliding motion of the pressing component 31 compresses the sliding frame 3 along its inclined surface, causing the sliding frame 3 to move upwards along the guide rod 2 connected by the spring 4. The guide rod 2 then moves the crossbar 6 upwards. Subsequently, the connecting frame 5, the crossbar 6, and the square cylinder 71 work together to move the moving contact 72 connected to the square cylinder 71 downwards until the moving contact 72 contacts the stationary contact 9, thus connecting the internal circuitry of the mechanism housing. Conversely, opening the housing door disconnects the internal circuitry, allowing workers to maintain and repair the mechanism housing. During maintenance and repair, the worker slides the slide bar 11 to move it to the upper end of the sliding hole of the guide plate 12. Then, the slide bar 11 is released, and the slide bar 11 drives the connected square cylinder 71 to move upward and be limited and fixed, thereby separating the moving contact 72 from the stationary contact 9. At this point, the circuit inside the mechanism box is always disconnected. At this time, the connecting frame 5, the crossbar 6, and the square cylinder 71 are in a relatively stationary state after being limited by the slide bar 11. Then, when the box door is closed, the guide rod 2 remains relatively stationary as the pressing part 31 pushes the mounting frame 1 upward. At this time, the spring 4 is stretched, thereby achieving the effect of linkage failure, so as to avoid circuit and equipment failure caused by incorrect operation. Finally, after confirming that the maintenance or repair operation is correct, the box door is closed, and then the slide bar 11 is slid back to the initial position. The work is then completed.

[0026] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
