Description

Technical Field

[0001] This utility model relates to the field of building auxiliary equipment technology, specifically to an internal support kit for a pre-embedded electrical box. Background Technology

[0002] In the design of building walls, electrical boxes need to be embedded in some wall surfaces. In order to improve the overall integrity of the wall structure, such as to make the electrical box fit tightly with the wall, pre-embedded electrical boxes are usually used during the pouring process of the cavity.

[0003] Specifically, when using embedded electrical boxes, they typically need to be installed and fixed in the required location before wall pouring or masonry work can proceed. However, during construction, the embedded electrical box may be subjected to significant external pressure or impact during the pouring, vibration, and compaction of wall materials (such as concrete and bricks), leading to deformation or displacement. This deformation or displacement not only affects the appearance of the electrical box but may also affect the layout of its internal space, ultimately impacting the installation and functionality of internal electrical components and even creating safety hazards. Utility Model Content

[0004] This utility model provides an internal support kit for a pre-embedded electrical box. After being installed in the inner cavity of the pre-embedded electrical box, it can provide support for the box structure, thereby reducing the deformation caused by external pressure or impact on the electrical box during wall construction.

[0005] This utility model is achieved through the following technical solution:

[0006] An internal support kit for a pre-embedded electrical box includes: a base, several sets of support components circumferentially arranged on the base, and a limiting kit; the several sets of support components are movably installed on the base, each set of support components includes a support body, a sliding guide disposed on the support body, and a pressure-resistant component disposed on the support body at one end away from the base, the sliding guide has a guiding surface structure, and a height difference is formed between the guiding surface structure and the support body so that the end of the sliding guide away from the pressure-resistant component forms a locking end, the pressure-resistant component is used to abut against the inner wall of the pre-embedded electrical box; the limiting kit includes several sets of limiting top supports corresponding one-to-one with the support components, the number and arrangement orientation of the limiting top supports are adapted to the number and arrangement orientation of the support components; wherein, one end of the limiting top support has a sliding auxiliary block adapted to the guiding surface structure, and the sliding auxiliary block can engage and fix with the locking end.

[0007] As a further improvement of this utility model, the guide surface structure includes a guide groove adapted to the sliding auxiliary block.

[0008] As a further improvement of this utility model, a guide arc surface structure is provided between the guide groove and the engaging end.

[0009] As a further improvement of this utility model, the sliding auxiliary block includes two sets of cylindrical friction-reducing blocks disposed on both sides of the limiting top support block, and the cylindrical friction-reducing blocks can be embedded in the guide groove.

[0010] As a further improvement of this utility model, the anti-compression component is installed on the support body via a movable connector.

[0011] As a further improvement of this utility model, a first buffer component is also connected between the anti-compression component and the support body.

[0012] As a further improvement of this utility model, a second buffer component is provided on the engaging end to abut against the sliding auxiliary block.

[0013] As a further improvement of this utility model, an auxiliary gripping member is provided on the side of the limiting kit away from the support component.

[0014] As a further improvement of this utility model, a friction-enhancing structure is provided on the side of the base away from the installation position of the support component.

[0015] As a further improvement of this utility model, the pressure-resistant component includes a pressure-bearing plate, which is tightly fitted to the inner wall of the pre-embedded electrical box.

[0016] The beneficial effects of this utility model include:

[0017] (1) In the inner support kit of this utility model, the support components can move relative to the base. Therefore, before and after the support work, the inner support kit can be stored as a whole by driving several sets of support components to move closer together, so that the kit can be used for the support work of multiple sets of pre-embedded electrical boxes.

[0018] (2) During the construction of the wall, the embedded electrical box will be under pressure for a long time until the wall is completed. Therefore, the pressure on the internal support kit installed in the embedded electrical box will last for a long time. Compared with some internal support kits in the prior art, which mainly rely on the structure of threads to share or bear the pressure after being under pressure, in this utility model, when the internal support kit is fully unfolded to provide support for the embedded electrical box, it mainly forms a complete support plate after the support component and the limiting kit are connected to each other and bear the horizontal or vertical pressure as a whole. Compared with the use of easily worn structures such as threads to bear pressure, the possibility of the internal support kit being damaged after long-term pressure is greatly reduced under the structure of this utility model, and thus it is more suitable for the use environment of the embedded electrical box.

[0019] (3) In the preferred structure, buffer components are provided between the anti-compression component and the support body, and between the locking end and the sliding auxiliary block. Therefore, on the one hand, when the pre-embedded electrical box is impacted, the buffer component can absorb the impact force, reducing the possibility that the pre-embedded electrical box will be subjected to excessive force and deformed directly. On the other hand, after the inner support kit is fully deployed, the anti-compression component in the support component, the support body and the limiting top support block in the limiting kit together form a complete support plate. The buffer component between the three can also be used to release the internal stress generated when the support plate is under pressure, avoiding the situation where the inner support kit is damaged by internal stress during long-term pressure.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0029] This embodiment provides an internal support kit for a pre-embedded electrical box, such as... Figures 1-3 As shown, it mainly includes a base 1, several sets of support components 2 and a limiting kit 3.

[0030] In this embodiment, since the pre-embedded electrical box has a rectangular structure, four sets of support components 2 are provided to support its upper and lower side walls and left and right side walls, such as... Figure 1 and 3 As shown, four sets of support components 2 are circumferentially arranged on the base 1 and are movably connected by hinges. Each support component 2 includes a support body 201, a sliding guide 202 disposed on the support body 201, and a pressure-resistant component 203 disposed on the support body 201 at one end away from the base 1. The sliding guide 202 has a guide surface structure 202-1, and a height difference is formed between the guide surface structure 202-1 and the support body 201 so that the end of the sliding guide 202 away from the pressure-resistant component 203 forms a locking end 204. This sliding guide 202 is used to cooperate with the limiting kit 3. The pressure-resistant component 203 includes a pressure-resistant supporting surface, which is mainly used to directly bear pressure by contacting the inner wall of the electrical box.

[0031] Under the structure of the aforementioned support component 2, the corresponding... Figure 2 and 3 As shown, the limiting kit 3 includes four sets of limiting support blocks 301 that correspond one-to-one with the support component 2. Since the support component 2 has four orientations (up, down, left, and right) in this embodiment, the four sets of limiting support blocks 301 are also arranged according to these four orientations. Simultaneously, a sliding auxiliary block 302 adapted to the guide surface structure 202-1 is formed at one end of the limiting support block 301. This sliding auxiliary block 302 can also be engaged and fixed with the engaging end 204.

[0032] Therefore, under the above structure, the usage process of the internal support kit is as follows:

[0033] Firstly, as Figure 4 As shown, the not-fully-deployed inner support kit is placed into the electrical box. At this time, the four support components 2 are still in a retracted state, and the anti-compression component 203 has not yet come into contact with the inner wall of the electrical box. In this state, the sliding auxiliary block 302 on the limiting top support block 301 is in contact with the guide surface structure 202-1 on the sliding guide 202 and can slide relative to each other on the guide surface structure 202-1. Subsequently, the user can push the limiting kit 3 to bring it closer to the position of the base 1. During this process, the sliding auxiliary block 302 will also slide away from the position of the anti-compression component 203 on the guide surface structure 202-1. During the sliding of the sliding auxiliary block 302, it will also force the support component 2 to rotate and approach a horizontal state with the base 1. Until the support component 2 rotates to the position of the base 1, the user can push the limiting kit 3 to bring it closer to the position of the base 1. Figure 5 In the state shown, the four sets of support components 2 are in the deployed state. At this time, the sliding auxiliary block 302 also slides out from the guide surface structure 202-1 and abuts against the engaging end 204, so as to... Figure 5 Taking the shown perspective as an example, at this time, the upper and lower pressure-resistant components 203 are tightly fitted to the upper and lower inner walls of the electrical box, respectively. Between the two, the supporting body 201, the sliding guide 202 and the limiting top support block 301 together form the main support plate and provide support for the upper and lower pressure-resistant components 203.

[0034] During the unfolding process of the inner support component in this embodiment, when the limiting kit 3 moves towards the base 1, it will simultaneously drive the four sets of support components 2 to rotate and achieve the overall unfolding of the inner support kit. This means that if the initial position of the base 1 is not placed in the center of the electrical box, during the unfolding process of the inner support kit, the anti-compression component 203, which is the first to contact the inner wall, will be subjected to a reaction force that causes the position of the base 1 to be slightly adjusted and placed back in the center of the electrical box. This also ensures that after the inner support kit is fully unfolded, all four sets of support components 2 can fit tightly against the inner wall of the electrical box to provide a uniform and stable support effect.

[0035] Preferably, such as Figure 1 and Figure 4 As shown, the guide surface structure 202-1 includes a guide groove 202-2 adapted to the sliding auxiliary block 302. This structure avoids situations such as the sliding auxiliary block 302 falling off from the guide surface structure 202-1.

[0036] Preferably, a guide arc surface structure 202-3 is connected between the guide groove 202-2 and the engaging end 204. This structure allows the inner support assembly to... Figures 4 to 5During the state transition shown, that is, the sliding auxiliary block 302 slides on the guide surface structure 202-1 away from the position of the anti-compression component 203 and finally slides off the guide surface structure 202-1 and abuts against the engaging end 204, the process of disengaging from the guide surface structure 202-1 and embedding into the engaging end 204 is smoother, thus making the overall unfolding process of the inner support kit smoother.

[0037] Preferably, such as Figure 2 As shown, the sliding auxiliary block 302 includes two sets of cylindrical friction-reducing blocks disposed on both sides of the limiting support block 301. The cylindrical friction-reducing blocks can be embedded in the guide groove 202-2, further preventing the sliding auxiliary block 302 from falling off the guide surface structure 202-1. This structure also reduces the requirements for the user's force direction on the limiting kit 3 during the unfolding of the inner support kit, making the overall use of the inner support kit more convenient.

[0038] Preferably, such as Figure 1 As shown, the pressure-resistant component 203 is mounted on the support body 201 via a movable connector 205. In this embodiment, the movable connector 205 is a hinged structure. Typically, to ensure a tight fit between the pressure-resistant component 203 and the inner wall of the electrical box, an interference fit must be formed between the inner support kit and the inner cavity of the electrical box. That is, before the inner support kit is fully deployed, the pressure-resistant component 203 needs to be in contact with the inner wall. After connecting the pressure-resistant component 203 to the support body 201 via the movable connector 205, the pressure-resistant component 203 can rotate relative to the support body 201 after initial contact with the inner wall, thus fully fitting against the inner wall of the electrical box. This avoids damage to both the pressure-resistant component 203 and the inner wall caused by its sharp edges or other contact. Furthermore, during the subsequent deployment of the inner support kit, the pressure-resistant component 203 can continue to rotate relative to the support body 201, ensuring that the pressure-resistant component 203 remains tightly fitted against the inner wall throughout the subsequent deployment process.

[0039] Preferably, such as Figure 1 and Figure 5 As shown, a first buffer component 206 is also connected between the anti-compression component 203 and the support body 201. In this embodiment, the first buffer component 206 is a spring component disposed on both sides of the movable connector 205. The first buffer component 206 can also be any component or kit that can provide a buffering effect, such as a support block supported by buffering material.

[0040] Preferably, the engaging end 204 is provided with a second buffer component that abuts against the sliding auxiliary block 302. In this embodiment, the second buffer component is a buffer layer structure that is attached to the engaging end 204. The buffer layer structure is made of buffer material such as rubber. The second buffer component can also be any component or kit that can provide a buffering effect, such as an elastic component.

[0041] Both the first buffer component 206 and the second buffer component can absorb the impact force, reducing the possibility of the embedded electrical box deforming significantly due to excessive force. Simultaneously, after the inner support assembly is fully deployed, when the anti-compression component 203 in the support assembly 2, the support body 201, and the limiting top support block 301 in the limiting assembly 3 together form a complete support plate, the buffer components among them can also release the internal stress generated when the support plate is under overall pressure, preventing damage to the inner support assembly due to internal stress during long-term pressure.

[0042] Preferably, the limiting kit 3 is provided with an auxiliary grip 303 on the side away from the support component 2. This component makes it convenient for the user to apply pushing and pulling force to the limiting kit 3. In particular, after the electrical box is supported, the user can pull the limiting kit 3 through this component and drive the sliding auxiliary block 302 on it to disengage from the engagement with the locking end 204, thereby facilitating the folding and storage of the inner support kit.

[0043] Preferably, a friction-enhancing structure is provided on the side of the base 1 away from the installation position of the support component 2. When placing the base 1 in the electrical box, after the user places the inner support kit in place, they can first... Figure 4 As shown, this forces the base 1 to fit tightly against the inner wall of the electrical box. At this time, the grinding structure is used to prevent the base 1 from shifting or deviating during the subsequent unfolding process, thus accelerating the rapid and smooth unfolding of the inner support kit.

[0044] Preferably, such as Figure 1 and Figure 5 As shown, the pressure-resistant component 203 includes a pressure-bearing plate 203-1, which is tightly fitted to the inner wall of the pre-embedded electrical box. The pressure-bearing plate 203-1 has a large contact area, thus providing a more uniform support effect for the wall of the electrical box and avoiding situations where only a certain point is supported while other points deform.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features.
