Description

Technical Field

[0001] This utility model belongs to the field of electrical engineering technology, specifically relating to automated protection devices for electrical engineering. Background Technology

[0002] The traditional, broad definition of electrical engineering refers to the sum of disciplines related to the creation of electrical and electronic systems. However, with the rapid development of science and technology, the concept of electrical engineering has far exceeded the scope of the above definition. A professor at Stanford University pointed out: "Today's electrical engineering covers almost all engineering activities related to electronics and photonics."

[0003] In the field of electrical engineering, automated equipment typically requires protective devices to prevent damage to internal precision components from dust, moisture, or external forces. Existing protective devices often employ bolt-fixed or snap-fit ​​structures, which present the following problems:

[0004] 1. Low assembly and disassembly efficiency: Traditional bolt fixing methods require tools, which are cumbersome to operate and take a long time to maintain or repair; although the snap-fit ​​structure simplifies assembly and disassembly, it is prone to loosening or wear after long-term use, resulting in unreliable connection.

[0005] 2. Insufficient positioning accuracy: The connection between the protective plate and the protective shell lacks a precise guiding structure, making it prone to misalignment during installation and affecting the sealing performance. Utility Model Content

[0006] The purpose of this invention is to provide an automated protection device for electrical engineering, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] Automated protection devices for electrical engineering include:

[0009] A storage protective case, wherein a protective plate is detachably connected to the upper end of the storage protective case;

[0010] Two sets of disassembly and assembly mechanisms are provided. Each set of disassembly and assembly mechanisms consists of two hook grooves, a first connecting plate, a second connecting plate, two hook claws, two pulling blocks, a support plate, two force-bearing blocks, and two springs. The first connecting plate and the second connecting plate are respectively fixedly connected to one end of the protective plate and the storage protective shell. The support plate is fixedly connected to the upper end of the first connecting plate. The two hook grooves are respectively opened at both ends of the second connecting plate. The two hook claws are rotatably connected to both ends of the first connecting plate through rotating shafts, and the two hook claws are respectively engaged in the two hook grooves. The support plate is fixedly connected to the upper end of the first connecting plate. The two pulling blocks are respectively fixedly connected to the upper ends of the two hook claws. The two force-bearing blocks are rotatably connected to the adjacent ends of the two pulling blocks through rotating rods. The two springs are respectively fixedly connected to both ends of the support plate, and the other ends of the two springs are respectively fixedly connected to the adjacent ends of the two force-bearing blocks.

[0011] As a preferred embodiment of this utility model, both ends of the support plate are fixedly connected with telescopic rods, and the other ends of the two telescopic rods are respectively fixedly connected to the adjacent ends of the two force-bearing blocks.

[0012] As a preferred embodiment of this utility model, the upper end of the protective plate is provided with multiple docking holes, and the upper end of the storage protective shell is fixedly connected with multiple positioning rods, wherein the multiple positioning rods and the multiple docking holes are matched.

[0013] As a preferred embodiment of this utility model, a lever is fixedly connected to the upper end of each of the two force-bearing blocks.

[0014] As a preferred embodiment of this utility model, both ends of the storage protective shell are fixedly connected to connecting plates, and both connecting plates are threaded with threaded rods.

[0016] In a preferred embodiment of this utility model, the observation window is made of a transparent composite board, and the lever is made of rubber.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this solution, the hook claw and hook groove are used in combination with the linkage reset structure of spring and telescopic rod. The protection plate can be unlocked by simply pressing the toggle block. No tools are required for operation. In addition, the telescopic rod restricts the extension and retraction path of the spring to avoid displacement and extend service life.

[0019] 2. In this solution, the positioning rod on the storage protective shell matches the docking hole of the protective plate to ensure quick alignment during installation and avoid sealing failure caused by misalignment of the protective plate. The observation window made of transparent composite board is wear-resistant and impact-resistant, and can directly observe the internal status of the equipment, reducing unnecessary disassembly operations.

[0020] 3. In this solution, the threaded rod and the connecting plate work together to fix the entire device to the equipment frame, preventing loosening caused by vibration; at the same time, the hook claw provides double locking, improving the stability of the protection.

[0028] Example 1

[0029] Please see Figure 1-4 The present invention provides the following technical solution:

[0030] Automated protection devices for electrical engineering include:

[0031] Storage protective shell 1, with a protective plate 5 detachably connected to the upper end of the storage protective shell 1;

[0032] Two sets of disassembly and assembly mechanisms are provided. Each set consists of two hook grooves, a first connecting plate 7, a second connecting plate 8, two hook claws 9, two pulling blocks 10, a support plate 13, two force-bearing blocks 12, and two springs 14. The first connecting plate 7 and the second connecting plate 8 are respectively fixedly connected to one end of the protective plate 5 and the storage protective shell 1. The support plate 13 is fixedly connected to the upper end of the first connecting plate 7. The two hook grooves are respectively opened at both ends of the second connecting plate 8. The two hook claws 9 are rotatably connected to both ends of the first connecting plate 7 through a rotating shaft, and the two hook claws 9 are respectively engaged in the two hook grooves. The support plate 13 is fixedly connected to the upper end of the first connecting plate 7. The two pulling blocks 10 are respectively fixedly connected to the upper ends of the two hook claws 9. The two force-bearing blocks 12 are respectively rotatably connected to the adjacent ends of the two pulling blocks 10 through a rotating rod. The two springs 14 are respectively fixedly connected to both ends of the support plate 13, and the other ends of the two springs 14 are respectively fixedly connected to the adjacent ends of the two force-bearing blocks 12.

[0033] In a specific embodiment of this utility model,

[0034] The top edge of the storage protective shell 1 is provided with two sets of symmetrically distributed disassembly and assembly mechanisms. The protective plate 5 is detachably fixed to the storage protective shell 1 through the two sets of mechanisms. The disassembly and assembly mechanism operation flow is as follows:

[0035] 1. Installation: Align the first connecting plate 7 of the protective plate 5 with the second connecting plate 8 of the storage protective shell 1, press down on the protective plate 5, and the hook claw 9 will rotate inward under the guidance of the inclined surface of the second connecting plate 8 until the hook claw 9 is engaged in the hook groove; at this time, the spring 14 provides tension through the support plate 13 to keep the hook claw 9 locked.

[0036] 2. Disassembly: Press the two side levers 11, the force block 12 rotates around the rotating rod and stretches the spring 14, and the pulling block 10 drives the hook claw 9 to rotate outward and disengage from the hook groove, so that the protective plate 5 can be lifted.

[0037] This device requires no tools to operate, and the telescopic rod 15 restricts the extension and retraction path of the spring 14, preventing deviation and extending its service life.

[0038] Please refer to the details. Figure 2 Both ends of the support plate 13 are fixedly connected to telescopic rods 15. The other ends of the two telescopic rods 15 are fixedly connected to the close ends of the two force blocks 12 respectively. The upper end of the protective plate 5 is provided with multiple docking holes. The upper end of the storage protective shell 1 is fixedly connected with multiple positioning rods 4. The multiple positioning rods 4 and the multiple docking holes are matched.

[0039] In this embodiment: the telescopic rod 15 consists of an outer tube and an inner rod. The end of the inner rod is fixed to the force-bearing block 12, and the outer tube is fixed on the support plate 13. When disassembling, the force-bearing block 12 moves to drive the inner rod to retract into the outer tube, which restricts the extension and retraction path of the spring 14 and prevents the spring 14 from shifting laterally. When installing, the positioning rod 4 is inserted into the docking hole to restrict the lateral displacement of the protective plate 5 and ensure that the hook claw 9 is accurately aligned with the hook groove.

[0040] Please refer to the details. Figure 2 Both load-bearing blocks 12 are fixedly connected to the upper ends of the two load-bearing blocks 12. Both ends of the storage protective shell 1 are fixedly connected to the connecting plates 2. Both connecting plates 2 are threadedly connected to the threaded rods 3. The upper end of the protective plate 5 is provided with an observation window 6. The observation window 6 is made of transparent composite board. The material of the connecting plate 11 is rubber.

[0041] In this embodiment: During operation, the finger presses the inclined surface of the lever block 11, which amplifies the force through the lever principle and reduces the force required for disassembly. During installation, the threaded rod 3 is rotated to adjust the tightening length to adapt to different thicknesses of the mounting surface, such as the cabinet wall or bracket, so as to achieve overall fixation of the device. The display screen data of the device inside the storage protective shell 1 can be directly read through the observation window 6 without disassembling the protective plate 5.

[0042] Working principle and usage process of this utility model:

[0043] The top edge of the storage protective shell 1 is provided with two sets of symmetrically distributed disassembly and assembly mechanisms. The protective plate 5 is detachably fixed to the storage protective shell 1 through the two sets of mechanisms. The disassembly and assembly mechanism operation process is as follows: Align the first connecting plate 7 of the protective plate 5 with the second connecting plate 8 of the storage protective shell 1, press the protective plate 5 down, and the hook claw 9 is guided by the inclined surface of the second connecting plate 8 to rotate inward until the hook claw 9 is engaged in the hook groove; at this time, the spring 14 provides tension through the support plate 13 to keep the hook claw 9 locked. Press the two side levers 11, the force block 12 rotates around the rotating rod and stretches the spring 14, and the pulling block 10 drives the hook claw 9 to rotate outward and disengage from the hook groove, so that the protective plate 5 can be lifted.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
