Description

Technical Field

[0001] This utility model relates to the field of electrical automation technology, and in particular to a maintenance and protection device for electrical automation equipment. Background Technology

[0002] During the maintenance of electrical automation equipment, protective devices are generally needed to protect the components on the equipment. When maintaining electrical automation control devices, the control terminals are located inside the distribution box. Due to the small space and numerous terminals in the distribution box, it is inconvenient for workers to remove screws, which may easily fall off. Since screws are conductors, falling off can easily cause a short circuit in the internal wiring of the distribution box, resulting in unnecessary losses.

[0003] Chinese Patent CN216720745U discloses a maintenance and protection device for electrical automation equipment. This device uses a designated slot to catch fallen screws, preventing them from interfering with workers' work and creating safety hazards. It also facilitates the categorization and storage of unused parts. Magnets are used to hold fallen screws, preventing them from falling out of the slot. However, while solving these problems, this maintenance and protection device has the following drawbacks:

[0004] After the electrical automation equipment maintenance and protection device is installed, the spring and slider B provide an outward pushing force to the movable plate, fixing the device to both sides inside the electrical box. However, the force provided by the spring is limited, making it impossible to place heavy maintenance tools on the surface of the device placement plate. When the staff performs maintenance, they need to place and retrieve the tools back and forth, which reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose an electrical automation equipment maintenance and protection device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of this utility model provides an electrical automation equipment maintenance and protection device, including a placement plate. A sliding groove is provided inside one side of the placement plate, and a movable plate is slidably connected inside the sliding groove. A rotating groove is provided inside one side of the movable plate, and a threaded rod is rotatably connected inside the rotating groove. A threaded cylinder is threadedly connected to the surface of the threaded rod, and a pressing plate is fixedly connected to one end of the threaded cylinder. A T-shaped groove is provided on one side of the movable plate, and a T-shaped rotating rod is rotatably connected inside the T-shaped groove.

[0008] Preferably, one end of the T-shaped rotating rod is fixedly connected to the surface of the threaded rod, thereby making it easier to rotate the threaded rod and thus making the device easier to install.

[0009] Preferably, one of the above solutions is that a limiting groove is symmetrically provided on one side of the movable plate, and a limiting rod is slidably connected inside the limiting groove. One end of the limiting rod is fixedly connected to one side of the extrusion plate. The limiting groove and the limiting rod prevent the extrusion plate from rotating with the threaded rod when the threaded rod rotates.

[0010] Preferably, one side of the placement plate has a through hole, and a threaded seat is fixedly connected to the outside of the through hole. A bolt is threaded into the inside of the threaded seat. The bolt and the threaded seat enable the placement plate and the movable plate to be fixed when stretched to a suitable length, thereby improving the stability of the device.

[0011] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0012] 1. During installation, the electrical automation equipment maintenance and protection device is installed by pulling the placement plate and movable plate to a suitable distance and then turning the bolts to fix the movable plate and placement plate together. Then, the T-shaped rotating rod is turned to drive the threaded rod to rotate. The threaded rod drives the threaded cylinder and the extrusion plate to move outward under the action of the limiting groove and the limiting rod, so that the anti-slip pad is attached to the inner wall of the electrical box to complete the fixation. Since the extrusion plate is fixed by the threaded rod and the threaded cylinder, it can withstand greater pressure, so the staff can place the maintenance tools on the top of the device, which is more convenient and improves work efficiency.

[0013] 2. The maintenance and protection equipment for this electrical automation equipment is equipped with shock-absorbing pads on the top of both the movable plate and the placement plate. When screws are disassembled by the staff and fall onto the shock-absorbing pads, they will not bounce off and fall outside the device due to the action of the shock-absorbing pads, thus making the device highly safe.

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] Example 1:

[0020] like Figure 1-3 As shown, this embodiment of an electrical automation equipment maintenance and protection device includes a placement plate 1. A sliding groove 2 is formed inside one side of the placement plate 1. Support rods 12 are symmetrically fixedly connected to one side of the sliding groove 2. A support groove 13 is formed on one side of a movable plate 3. The surface of the support rod 12 is slidably connected to the interior of the support groove 13. When using this device, the operator stretches the placement plate 1 and the movable plate 3 to a suitable length under the constraint of the support groove 13 and the support rod 12. The movable plate 3 is slidably connected inside the sliding groove 2. A limit groove 10 is symmetrically formed on one side of the movable plate 3. A limit rod 11 is slidably connected inside the limit groove 10. One end of the limit rod 11 is fixedly connected to one side of a pressing plate 7. When the pressing plate 7 moves under the action of the threaded rod 5 and the threaded cylinder 6... When in motion, the limiting rod 11 and the limiting groove 10 work together to firmly restrict the rotation of the extrusion plate 7 and the threaded cylinder 6, so that the extrusion plate 7 moves under the action of the rotation of the threaded rod 5. A rotating groove 4 is opened inside one side of the movable plate 3, and a threaded rod 5 is rotatably connected inside the rotating groove 4. A threaded cylinder 6 is threadedly connected to the surface of the threaded rod 5, and one end of the threaded cylinder 6 is fixedly connected to the extrusion plate 7. A T-shaped groove 8 is opened on one side of the movable plate 3, and a T-shaped rotating rod 9 is rotatably connected inside the T-shaped groove 8. One end of the T-shaped rotating rod 9 is fixedly connected to the surface of the threaded rod 5. When the operator moves the T-shaped rotating rod 9 inside the T-shaped groove 8, it drives the threaded rod 5 to rotate. Under the action of the thread, the threaded rod 5 drives the threaded cylinder 6 to move on the surface of the threaded rod 5, thereby the threaded cylinder 6 drives the extrusion plate 7 to move.

[0021] Both the top of the placement plate 1 and the top of the movable plate 3 are equipped with shock-absorbing pads 14. The shock-absorbing pads 14 can prevent disassembled screws or small components from bouncing or being damaged when they fall into the top of the placement plate 1 and the movable plate 3. Both one side of the placement plate 1 and one side of the pressing plate 7 are equipped with anti-slip pads 15. When the pressing plate 7 moves, it causes the anti-slip pads 15 to fit against the inner wall of the electrical box, which can fix the device relatively stably. One side of the placement plate 1 has a through hole 16. A threaded seat 17 is fixedly connected to the outside of the through hole 16. A bolt 18 is threadedly connected inside the threaded seat 17. When the placement plate 1 and the movable plate 3 are stretched to a suitable length, the bolt 18 is rotated. Under the action of the threaded seat 17, one end of the bolt 18 fits against one side of the movable plate 3, thus completing the fixation.

[0022] The working principle of an electrical automation equipment maintenance and protection device according to this embodiment is as follows:

[0023] When using this electrical automation equipment maintenance and protection device, first stretch the placement plate 1 and the movable plate 3 to a suitable length, then rotate the bolt 18. Under the action of the threaded seat 17, one end of the bolt 18 fits against one side of the movable plate 3, completing the fixation. Then, the operator lifts the device to a suitable position. When the operator moves the T-shaped rotating rod 9 inside the T-slot 8, it drives the threaded rod 5 to rotate. Under the action of the thread, the threaded rod 5 drives the threaded cylinder 6 to move on the surface of the threaded rod 5. Thus, the threaded cylinder 6 drives the pressing plate 7 to move. When the pressing plate 7 moves, it causes the anti-slip pad 15 to fit against the inner wall of the electrical box, which can fix the device relatively stably. At the same time, the setting of the shock-absorbing pad 14 can prevent the screws or small components that are removed from falling into the top of the placement plate 1 and the movable plate 3 from bouncing up or being damaged.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. During the installation of this electrical automation equipment maintenance and protection device, the placement plate 1 and the movable plate 3 are pulled apart to a suitable distance, and then the bolt 18 is rotated to fix the movable plate 3 and the placement plate 1. Then, the T-shaped rotating rod 9 is turned to drive the threaded rod 5 to rotate. The threaded rod 5 drives the threaded cylinder 6 and the pressing plate 7 to move outward under the action of the limiting groove 10 and the limiting rod 11, so that the anti-slip pad 15 is attached to the inner wall of the electrical box to complete the fixation. Since the pressing plate 7 is fixed by the threaded rod 5 and the threaded cylinder 6, it can withstand greater pressure, so the staff can place the maintenance tools on the top of the device, which is more convenient and improves work efficiency.

[0026] 2. The electrical automation equipment maintenance and protection device is equipped with shock-absorbing pads 14 at the top of both the movable plate 3 and the placement plate 1. When the screws are disassembled by the staff and fall onto the shock-absorbing pads 14, the shock-absorbing pads 14 will prevent the screws from bouncing off and falling outside the device, thus making the device highly safe.
