Description

Technical Field

[0001] This utility model relates to the field of electrical fire protection device technology, and in particular to an embedded structure that facilitates the maintenance of electrical fire protection devices. Background Technology

[0002] Embedded electrical fire protection devices refer to devices installed within the internal structure of electrical equipment or systems. For example, in a distribution box, unlike traditional external devices that are mounted on the outer surface or side of the box, they are embedded into the internal frame or wall panel of the distribution box using specific mounting slots or holes. This is similar to a custom-made plug-in, precisely placed in a pre-reserved position inside the equipment, forming a seamless whole with the distribution box.

[0003] In existing technologies, electrical fire protection devices are typically fixed in electrical distribution boxes using either snap-fit ​​structures or bolts. While these methods are generally secure, maintenance or repairs usually require removing the device from the distribution box. Snap-fit ​​devices are inconvenient to remove, and their plastic casings are prone to damage during disassembly. Bolt fixation, on the other hand, is cumbersome, especially given the complex wiring and limited space within distribution boxes. Summary of the Invention

[0004] This utility model provides an embedded structure that facilitates the maintenance of electrical fire protection devices, thereby solving the problems in the background art.

[0005] This utility model adopts the following technical solution: an embedded structure for easy maintenance of electrical fire protection devices, including an inner wall of a distribution box and an electrical fire protection device. A mounting bracket is provided on the inner wall of the distribution box. The mounting bracket has symmetrical openings on its upper and lower sides. The electrical fire protection device has symmetrical mounting slots on its upper and lower sides. When the electrical fire protection device is located within the mounting bracket, each mounting slot corresponds to one opening. A fixing component is provided in each opening on the mounting bracket. Each set of fixing components is slidably installed in one of the openings on the mounting bracket, and the working end of each set of fixing components is connected to one mounting slot on the electrical fire protection device. Each set of mounting brackets also has a set of switch components. The switch components are connected to two sets of fixing components. Operation of the switch components can disengage the two sets of fixing components located in the mounting bracket from the electrical fire protection device. This solves the problem of inconvenient disassembly when the electrical fire protection device is fixed in the distribution box by a snap-fit ​​or bolt connection in the prior art.

[0006] Furthermore, each opening in the mounting bracket has symmetrically formed sliding grooves on both sides. Each sliding groove contains a connecting block and multiple springs. The multiple springs are all located at the bottom end inside the sliding groove. The connecting block is movably positioned within the sliding groove and is connected to the top of the multiple springs. The connecting block is slidably connected to one end of the fixing component. The sliding groove is used for inserting one end of the fixing component, and the connection between the connecting block and the fixing component through the multiple springs can restrict the fixing component.

[0007] Furthermore, each set of fixing components includes a connecting frame and a fixing block. Two connecting rods are symmetrically arranged at both ends of the connecting frame. Each connecting rod is located in a groove, and a sliding block is provided at the position of each connecting rod within the groove. Each sliding block is slidably installed in a connecting block. The fixing block is located at the bottom end of the connecting frame and is situated in a mounting slot. The fixing block secures the electrical fire protector by corresponding with the mounting slot. The two sets of fixing components are used to fix the electrical fire protector in the mounting frame.

[0008] Furthermore, the switch assembly includes connecting plates and a sliding bracket. Two connecting plates are provided, each connected to one end of a connecting bracket, and each connecting plate has a protrusion at its other end. The other ends of both connecting plates are located on one side of a mounting bracket, with a gap between them. A sliding bracket is provided on one side of the mounting bracket, located between the two connecting plates. One end of the sliding bracket has a top block, the size of which is larger than the gap between the two protrusions. The switch assembly is used to actuate the two sets of fixing components to loosen their fixation to the electrical fire protection device.

[0009] Furthermore, the mounting slot on the electrical fire protector is formed by multiple barbs, and its structure is similar to that of a cable tie. The mounting slot is used to cooperate with the fixing components to fix the electrical fire protector.

[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0011] In this application, the electrical fire protector can be slidably installed into the mounting bracket by embedding. In this case, only the front display surface and operating interface of the electrical fire protector are exposed within the mounting bracket, while the device itself is completely covered by the bracket. This allows the mounting bracket to protect the electrical fire protector. When the electrical fire protector slides into the mounting bracket, its top mounting slot connects with the working end of the fixing component. The working end of the fixing component secures the electrical fire protector in the mounting bracket. However, since the fixing component also uses a sliding connection within the mounting bracket, the operator can easily move the device between the fixing component and the electrical fire protector. After the fire protection device is connected, it is pulled out of the mounting bracket. However, due to the connection of the fixing components, the fire protection device cannot be moved outside the mounting bracket. This makes it convenient for maintenance personnel to test the fire protection device. If a problem is detected, the two fixing components can be loosened by operating the switch assembly, allowing the fire protection device to be removed from the mounting bracket. This installation method solves the problem of inconvenience in disassembling fire protection devices that are fixed in the distribution box by snap-fit ​​or bolt connections in the existing technology.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. 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 scope of protection of this utility model.

[0021] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-6 This utility model provides an embedded structure for easy maintenance of electrical fire protection devices, including an inner wall 1 of a distribution box and an electrical fire protection device 5. An installation bracket 2 is provided on the inner wall 1 of the distribution box. The installation bracket 2 has symmetrical openings 21 on its upper and lower sides. The electrical fire protection device 5 has symmetrical mounting slots 51 on its upper and lower sides. When the electrical fire protection device 5 is located within the installation bracket 2, each mounting slot 51 corresponds to one opening 21. Each opening 21 on the installation bracket 2 is equipped with a fixing component 3. Each set of fixing components 3 is slidably installed within the openings 21 on the installation bracket 2, and the working end of each set of fixing components 3 is connected to one mounting slot 51 on the electrical fire protection device 5. Each set of installation brackets 2 also has a set of switch components 4, which are connected to two sets of fixing components 3. Operation of the switch components 4 can disengage the two sets of fixing components 3 located in the installation bracket 2 from the electrical fire protection device 5.

[0023] In this application, the electrical fire protector 5 can be slidably installed into the mounting bracket 2 via an embedded method. At this time, only the front display surface and operating interface of the electrical fire protector 5 are exposed within the mounting bracket 2; the device itself is completely covered by the mounting bracket 2. Thus, the mounting bracket 2 can protect the electrical fire protector 5. When the electrical fire protector 5 slides into the mounting bracket 2, its top mounting slot 51 connects with the working end of the fixing component 3. The working end of the fixing component 3 can fix the electrical fire protector 5 in the mounting bracket 2. However, since the fixing component 3 also uses a sliding connection within the mounting bracket 2, the operator can easily access the device through the connection between the fixing component 3 and the electrical fire protector 5. After the gas fire protector 5 is connected, the electrical fire protector 5 is pulled out of the mounting bracket 2. However, due to the connection of the fixing component 3, the electrical fire protector 5 cannot be moved outside the mounting bracket 2. This makes it convenient for maintenance personnel to test the electrical fire protector 5. If a problem is detected in the electrical fire protector 5, the two fixing components 3 can be loosened from the electrical fire protector 5 by operating the switch component 4. In this way, the electrical fire protector 5 can be removed from the mounting bracket 2. This installation method solves the problem of inconvenience in disassembling the electrical fire protector 5 when it is fixed in the distribution box by the snap-on or bolt connection in the existing technology.

[0024] Preferably, each opening 21 in the mounting bracket 2 has symmetrically provided sliding grooves 22 on both sides. Each sliding groove 22 is provided with a connecting block 23 and multiple springs 24. The multiple springs 24 are all located at the bottom end inside the sliding groove 22. The connecting block 23 is movably located in the sliding groove 22 and is connected to the top of the multiple springs 24. The connecting block 23 is slidably connected to one end of the fixing component 3.

[0025] In this application, the sliding grooves 22 provided on both sides of each opening 21 on the mounting bracket 2 are used to insert one end of the fixing component 3. In this way, one end of the fixing component 3 can be located in the sliding groove 22 and connected to the connecting block 23. The connecting block 23 can restrict the fixing component 3 through the connection of multiple springs 24, so that the initial position of the fixing component 3 is fixed. When the fixing component 3 is connected to the electrical fire protection device 5 or moved by the switch component 4, the fixed component 3 after moving will be reset by the return force of the multiple springs 24.

[0026] Preferably, each set of fixing components 3 includes a connecting frame 31 and a fixing block 32. Two connecting rods 33 are symmetrically arranged at both ends of the connecting frame 31. Each connecting rod 33 is located in a slide groove 22, and a sliding block 34 is provided at the position of each connecting rod 33 in the slide groove 22. Each sliding block 34 is slidably installed in a connecting block 23. The fixing block 32 is located at the bottom end of the connecting frame 31 and is located in the mounting slot 51. The fixing block 32 fixes the electrical fire protection device 5 by corresponding with the mounting slot 51.

[0027] In this application, the connecting frame 31 is mounted on the connecting block 23 in the slide groove 22 via two connecting rods 33 and a sliding block 34 disposed on the connecting rods 33. The connecting frame 31 can move in the slide groove 22. The bottom end of the connecting frame 31 is disposed in the mounting slot 51 of the fixing block 32 to fix the electrical fire protection device 5.

[0028] Preferably, the switch assembly 4 includes a connecting plate 41 and a sliding bracket 42. There are two connecting plates 41, one end of which is connected to a connecting bracket 31. The other end of each connecting plate 41 is provided with a protrusion 411. The other ends of the two connecting plates 41 are located on one side of the mounting bracket 2, and there is a gap between the other ends of the two connecting plates 41. The sliding bracket 42 is provided on one side of the mounting bracket 2. The sliding bracket 42 is located between the two connecting plates 41. One end of the sliding bracket 42 is provided with a top block 421. The size of the top block 421 is larger than the gap between the two protrusions 411.

[0029] In this application, the connecting plate 41 is fixedly mounted on the connecting frame 31 and moves synchronously with the connecting frame 31, while the sliding frame 42 is slidably mounted on the side of the mounting frame 2 so that it can move on the mounting frame 2. When the sliding frame 42 moves, the top block 421 provided on one side of the sliding frame 42 will move towards the two protrusions 411. In this way, the top block 421 will open the two protrusions 411. After the protrusions 411 are opened, they will drive the connecting frame 31 to move through the connecting plate 41. In this way, the connecting frame 31 will drive the fixing block 32 to fall out of the mounting slot 51. In this way, the connection between the fixing component 3 and the electrical fire protection device 5 can be loosened.

[0030] Preferably, the mounting slot 51 provided on the electrical fire protection device 5 is formed by multiple barbs, and its structure is similar to that of a cable tie.

[0031] In this application, since the fixing component 3 can be adjusted on the mounting bracket 2, the electrical fire protection device 5 is also provided with multiple fixing positions in the mounting slot 51 for cooperating with the fixing block 32. The multiple barb positions provided in the mounting slot 51 can all be used to connect with the fixing block 32. In this way, the fixing component 3 can select the fixing position when fixing the electrical fire protection device 5.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
