Description

Technical Field

[0001] This utility model relates to the field of building installation engineering technology, and in particular to ALC wall panel embedded photovoltaic conduit pre-embedded connectors. Background Technology

[0002] With the development of green energy technologies, photovoltaic power generation systems are being used more and more widely in the building sector. In buildings using new building materials such as autoclaved lightweight concrete (ALC) wall panels, in order to maintain the aesthetics and integrity of the walls, it is usually necessary to pre-embed the conduits used for the photovoltaic system inside the walls.

[0003] Because of the limited length of a single conduit, when laying conduits over long distances inside walls, it is necessary to use pre-embedded connectors to connect multiple conduit sections to ensure the continuity of the wiring. Currently, common pre-embedded connectors mostly adopt simple sleeve structures, threaded connections, or snap-fit ​​connections.

[0004] However, these conventional connectors reveal significant shortcomings in the specific application of "embedded installation." For example, threaded connectors require considerable operating space to rotate the pipe or connector itself, which is nearly impossible within narrow pre-drilled holes in wall panels. While simple snap-fit ​​connections are convenient to install, their locking force is often limited, resulting in low reliability and a risk of detachment during subsequent concrete pouring or wall vibration. More critically, once the connector is embedded deep into the wall, construction workers cannot inspect it or apply additional locking force, making it difficult to guarantee the final connection state and posing a potential threat to the safety and stability of the entire photovoltaic system. Therefore, this invention proposes an ALC wall panel embedded photovoltaic conduit pre-embedded connector to address the shortcomings of existing technologies. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an embedded photovoltaic conduit connector for ALC wall panels, which aims to improve the problem that some embedded photovoltaic conduit connectors for ALC wall panels in the prior art are difficult to reliably lock after being embedded in the wall.

[0006] This utility model provides an embedded photovoltaic conduit pre-embedded connector for ALC wall panels, comprising: a round tube; and a locking mechanism disposed on the round tube.

[0007] The circular tube has a hollow cavity for accommodating the inlet and outlet pipes, and the tube wall is provided with a movable groove, a retaining groove and an inlet.

[0008] The locking mechanism includes a rotating ring that is rotatably sleeved on the outer wall of the circular tube. The inner wall of the rotating ring is provided with a sliding groove and a limiting groove. The locking mechanism also includes a locking plate, a T-block, a spring, and a locking block.

[0009] One end of the T-shaped block is slidably fitted into the groove, and the other end of the T-shaped block is fixedly connected to the clamping plate; the clamping plate is slidably disposed in the movable groove; the spring is disposed in the movable groove, one end of the spring abuts against the inner wall of the round tube, and the other end of the spring abuts against the clamping plate; the clamping block is fixedly connected to the clamping plate and can slide through the clamping groove to extend into the hollow cavity.

[0010] Preferably, the groove is a groove with an arc.

[0011] Preferably, the sliding groove, the limiting groove, the movable groove, the locking groove, and the inlet together constitute a groove assembly.

[0012] Preferably, the ALC wall panel embedded photovoltaic conduit pre-embedded connector further includes a protective mechanism disposed on the round tube.

[0013] More preferably, the protection mechanism includes a sealing layer disposed at the pipe joint to prevent external impurities from entering.

[0014] More preferably, the protection mechanism includes a protective layer covering the outer wall of the circular tube for protecting the connector body.

[0015] More preferably, the protection mechanism includes a protective layer covering the inner wall of the circular tube to prevent wear on the internal cables.

[0016] In a more specific implementation, the protection mechanism also includes a sealing layer disposed at the pipe joint, a protective layer covering the outer wall of the pipe, and a protective layer covering the inner wall of the pipe, to provide comprehensive protection.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a rotating ring that is rotatably sleeved on the outer wall of a circular tube, and opening a sliding groove in the inner wall of the rotating ring, slides and engages with a T-shaped block. The T-shaped block is fixedly connected to a locking plate, which is slidably set in a movable groove and abuts against a spring. The other end of the spring abuts against the inner wall of the circular tube. The locking plate is also fixedly connected to a locking block. This solves the problem that existing pre-embedded connectors are difficult to operate from the outside after installation, resulting in difficulty in locking or unreliable locking. It achieves the technical effect of convenient installation, simple operation, and automatic locking through spring force, and a stable and reliable connection.

[0018] 2. This utility model, by setting up a protective mechanism, including a sealing layer set at the interface of the round pipe, a protective layer covering the outer wall of the round pipe, and a protective layer covering the inner wall of the round pipe, solves the problem that existing connectors lack protection, which can lead to impurities entering the interface, easy damage to the body, and easy wear of internal cables during construction or use. It achieves a comprehensive protective effect of sealing and dust prevention, protecting the body, and preventing cable wear, thus extending the service life and improving electrical safety.

[0019] 3. This utility model cleverly converts the rotational motion of the rotating ring into the radial sliding motion of the card plate by opening a groove with an arc on the inner wall of the rotating ring and utilizing the sliding cooperation of the T-shaped block in the groove. This solves the problems of complex motion conversion structure or low transmission efficiency, and achieves the technical effect of compact structure, reliable motion conversion and clear transmission chain.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Reference Figures 1 to 4 This utility model provides an embedded photovoltaic conduit connector for ALC wall panels, which aims to solve the problem that existing embedded photovoltaic conduit connectors for ALC wall panels are difficult to reliably and securely lock after installation in the wall panel, and lack comprehensive protection for the connector body, interface and internal photovoltaic cables.

[0025] like Figure 1 As shown, the ALC wall panel embedded photovoltaic conduit pre-embedded connector includes a round tube 1 and a locking mechanism 2 set on the round tube 1. The round tube 1 has a hollow cavity for accommodating the inlet tube 4 and the outlet tube 5. The tube wall of the round tube 1 is provided with a movable groove 263, a locking groove 264 and an inlet 265. The locking mechanism 2 is used to lock the inlet tube 4.

[0026] like Figure 1 and Figure 3 As shown, the locking mechanism 2 includes a rotating ring 21 that is rotatably sleeved on the outer wall of the circular tube 1. The inner wall of the rotating ring 21 is provided with a sliding groove 261 and a limiting groove 262. The locking mechanism 2 also includes a locking plate 23, which is slidably disposed in the movable groove 263.

[0027] like Figure 2 As shown, the locking mechanism 2 also includes a T-shaped block 22, one end of which is slidably fitted into the slide groove 261, and the other end of which is fixedly connected to the locking plate 23. Figure 1 As shown, the locking mechanism 2 also includes a spring 24, which is disposed in the movable groove 263. One end of the spring 24 abuts against the inner wall of the round tube 1, and the other end of the spring 24 abuts against the locking plate 23. The locking mechanism 2 also includes a locking block 25, which is fixedly connected to the locking plate 23 and slides through the locking groove 264 to extend into the hollow cavity.

[0028] Reference Figures 1 to 3The core structure of the locking mechanism 2 is described in detail below: The locking mechanism 2 includes a rotating ring 21 rotatably sleeved on the outer wall of the circular tube 1. The inner wall of the rotating ring 21 has a sliding groove 261, which is an arc-shaped groove. The inner wall of the rotating ring 21 also has a limiting groove 262 for limiting the movement range of the T-shaped block 22. The locking mechanism 2 also includes a T-shaped block 22, one end of which is slidably fitted in the sliding groove 261 and limited to the movement range defined by the limiting groove 262. The wall of the circular tube 1 has a movable groove 263. The locking mechanism 2 also includes a locking plate 23, the other end of which is fixedly connected to the locking plate 23. The locking plate 23 is slidably disposed in the movable groove 263. The locking mechanism 2 also includes a spring 24, which is disposed in the movable groove 263. One end of the spring 24 abuts against... The spring 24 is attached to the inner wall of the circular tube 1, and the other end of the spring 24 abuts against the locking plate 23. The locking mechanism 2 also includes a locking block 25, which is fixedly connected to the locking plate 23 and faces the hollow cavity of the circular tube 1. The wall of the circular tube 1 is also provided with a locking groove 264. The locking block 25 can slide through the locking groove 264. When the rotating ring 21 rotates relative to the circular tube 1, the T-shaped block 22 moves under the arc guidance of the sliding groove 261. The T-shaped block 22 drives the locking plate 23 to slide in the movable groove 263. The sliding of the locking plate 23 compresses or releases the spring 24. The abutment force applied by the spring 24 drives the locking block 25 to extend or retract through the locking groove 264. At least one end of the circular tube 1 is also provided with an inlet 265. The sliding groove 261, the limiting groove 262, the movable groove 263, the locking groove 264 and the inlet 265 together constitute the groove assembly 26.

[0029] The groove 261 on the inner wall of the rotating ring 21 is a curved groove.

[0030] Reference Figures 1 to 3 The groove 261, the limiting groove 262, the movable groove 263, the locking groove 264 and the inlet 265 together constitute the groove assembly 26.

[0031] Reference Figure 1 , Figure 4 The connector also includes a protective mechanism 3 disposed on the circular tube 1. The protective mechanism 3 includes a sealing layer 31 disposed on the interface of the circular tube 1, a protective layer 32 covering the outer wall of the circular tube 1, and a protective layer 33 covering the inner wall of the circular tube 1. The protective mechanism 3 also includes a sealing layer 31 disposed on the interface of the circular tube 1, a protective layer 32 covering the outer wall of the circular tube 1, and a protective layer 33 covering the inner wall of the circular tube 1.

[0032] The implementation principle of this application embodiment is as follows: When it is necessary to connect the inlet pipe 4 and the outlet pipe 5, the inlet pipe 4 and the outlet pipe 5 are entered through the inlet 265. At the same time, the rotating ring 21 on the round pipe 1 is rotated. The rotating ring 21 has a sliding groove 261 and a limiting groove 262. Therefore, the movement of the rotating ring 21 will drive the T-block 22. Since the sliding groove 261 has an arc, when the T-block 22 moves, the T-block 22 will be pulled up under the action of the sliding groove 261. At this time, the card plate 23 connected to the T-block 22 will move along with the working space provided by the movable groove 263 opened in the round pipe 1. The spring 24, which is connected to the inner wall of the round pipe 1 at one end and to the card plate 23 at the other end, will be compressed and generate a reaction force, pushing the card block 25 connected to the card plate 23 into the card groove 264 opened on the inlet pipe 4. At this time, the inlet pipe 4 will be locked. The docking and fixing effect of the inlet pipe 4 and the outlet pipe 5 is achieved through the effect of the locking mechanism 2 and the groove assembly 26. Thanks to the function of the protection mechanism 3, the sealing layer 31 on the interface of the circular pipe 1 can effectively prevent external impurities from entering the pipe. The protective layer 32 on the outer wall of the circular pipe 1 plays a protective role, effectively preventing the circular pipe 1 from being damaged by internal equipment, and greatly extending the service life of the equipment. At the same time, the protective layer 33 on the inner wall of the circular pipe 1 can prevent the photovoltaic cable from being damaged, thereby causing losses. Overall, it plays a protective role and realizes the long-term stability of the equipment.
