Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical junction boxes, and in particular to a low-voltage electrical junction box used in integrated cabling projects. Background Technology

[0002] As a crucial component of integrated cabling systems, low-voltage junction boxes serve as concealed installation carriers for the terminal wiring of various low-voltage devices. They are typically embedded in building walls or floor structures using a pre-embedded method, providing a stable interface for the subsequent modular installation of standardized panels. In terms of materials, mainstream products utilize high-performance flame-retardant PVC engineering plastics or galvanized steel sheets, meeting building fire safety standards while also possessing excellent chemical corrosion resistance, mechanical pressure resistance, and electrical insulation properties. During installation, the conventional approach is to fill the pre-reserved grooves in the junction box with cement mortar and then embed the junction box within. However, this traditional process has several technical drawbacks: First, the manually filled cement mortar is often unevenly distributed around the junction box, leading to stress differences during curing due to inconsistent mortar expansion coefficients; second, the long curing time of the mortar leaves the junction box without effective fixation, making it highly susceptible to disturbance from external construction forces; and third, the uncertainty of mortar shrinkage and deformation can cause spatial displacement of the junction box. The combined effect of these factors may ultimately lead to the flatness of the junction box installation exceeding the allowable deviation, making it impossible for its front surface to remain coplanar with the wall finish, which seriously affects the standardized installation quality of subsequent modular panels. Utility Model Content

[0003] The main purpose of this utility model is to provide a low-voltage junction box for integrated cabling projects, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A low-voltage junction box for integrated cabling projects includes a junction box body. Two limiting components are symmetrically fixedly installed on the top wall of the junction box body. Each limiting component consists of a fixed base plate and a retraction spring. The retraction spring is fixedly installed on the inner end of the fixed base plate. Two support components are slidably installed inside the junction box body. The support components are simultaneously slidably installed on the limiting components. Each support component consists of a movable plate, a rubber pad, and a mounting rod. The rubber pad is fixedly installed on the inner end of the movable plate, and the mounting rod is fixedly installed inside the movable plate. A fixing component is movably installed inside the junction box body and between the two support components. The fixing component consists of a lead screw, an internal hexagonal column, and a triangular compression plate. The internal hexagonal column is fixedly installed on the front end of the lead screw, and the triangular compression plate is installed on the lead screw.

[0006] Preferably, an installation through groove is provided on the upper side of the rear wall of the main body of the dark box, and two connecting through grooves are symmetrically provided on the upper side of the inner walls on the left and right sides of the main body of the dark box.

[0007] Preferably, the fixing base plate on the limiting component is fixedly installed on the upper inner wall of the dark box body, and the fixing base plate has a through hole, and the contraction spring is coaxial with the through hole.

[0008] Preferably, the support component passes through the through slot in the main body of the cassette, and the movable plate is provided with a connecting guide groove that passes through the movable plate vertically.

[0009] Preferably, the movable plate is sleeved on the limiting assembly via a connecting guide groove, and the mounting rod is fixedly installed in the connecting guide groove, passing through both the retraction spring and the through hole.

[0010] Preferably, the lead screw on the fixing component is rotatably installed in the mounting slot opened on the cassette body, and the internal hexagonal column is located inside the cassette body.

[0011] Preferably, the triangular extrusion plate has a threaded hole, the triangular extrusion plate is mounted on the lead screw through the threaded hole, and the upper end of the triangular extrusion plate is in contact with the upper inner wall of the cassette body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating limiting components, supporting components, and fixing components within the main body of the junction box, the fixing components push the supporting components outward, causing them to press against the inner wall of a pre-reserved groove in the main body of the junction box, thus pre-fixing the main body. This design effectively solves the problem of junction box displacement caused by uneven cement mortar filling, long curing time, and shrinkage deformation in traditional processes, ensuring the stability and flatness of the main body installation and avoiding deviations during subsequent modular panel installation. Furthermore, the synergistic effect of the limiting component and the supporting components further enhances the junction box's resistance to disturbance during construction, improving construction efficiency and quality, and reducing rework and material waste caused by improper installation. In addition, the limiting components can limit the supporting components during storage and transportation, ensuring they retract completely into the main body, preventing the support components from increasing storage and transportation space, and avoiding structural damage or transportation safety hazards caused by accidental extension of the supporting components.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 - Figure 4As shown, a low-voltage junction box for integrated cabling projects includes a junction box body 1. Two limiting components 2 are symmetrically fixedly installed on the top wall of the junction box body 1. Each limiting component 2 consists of a fixed base plate 7 and a retraction spring 8. The retraction spring 8 is fixedly installed on the inner end of the fixed base plate 7. Two support components 3 are slidably installed inside the junction box body 1, and are simultaneously slidably installed on the limiting components 2. Each support component 3 consists of a moving plate 10, a rubber pad 11, and a mounting rod 12. The rubber pad 11 is fixedly installed on the inner end of the moving plate 10, and the mounting rod 12 is fixedly installed inside the moving plate 10. A fixing component 4 is movably installed inside the junction box body 1 and between the two support components 3. The fixing component 4 consists of a lead screw 13, an internal hexagonal column 14, and a triangular compression plate 15. The internal hexagonal column 14 is fixedly installed on the front end of the lead screw 13, and the triangular compression plate 15 is installed on the lead screw 13. An installation through groove 5 is opened on the upper side of the rear wall of the junction box body 1. Two connecting through grooves 6 are symmetrically opened on the upper side of the inner walls on the left and right sides of the junction box body 1. During transportation and storage... In the process, the support component 3 is completely retracted into the main body 1 of the junction box by the elastic force of the retraction spring 8, avoiding taking up extra space or causing damage. When installing the main body 1 of the junction box, the main body 1 of the junction box is embedded into the groove reserved in the wall, and its position is initially adjusted to ensure that the front surface of the main body 1 of the junction box is parallel to the wall finish. Then, a hex wrench is inserted into the internal hexagonal post 14, and the screw 13 is rotated clockwise, which drives the triangular pressing plate 15 to move backward along the screw 13. At this time, the inclined surface of the triangular pressing plate 15 will press the moving plates 10 on both sides, pushing the support component 3 to slide outward, until the rubber pad 11 of the support component 3 is tightly pressed against the inner wall of the groove. Pre-fixation is achieved through friction and elastic deformation. At this time, the retraction spring 8 will be compressed by the moving plate 10, providing a reverse force to enhance stability. After confirming that the main body 1 of the junction box is stable, cement mortar can be filled into the groove. Since the support component 3 has provided temporary fixation for the main body 1 of the junction box, there is no need to worry about the displacement of the main body 1 of the junction box when filling the mortar. After filling, wait for the mortar to cure.

[0021] Specifically, the fixing base plate 7 on the limiting component 2 is fixedly installed on the upper inner wall of the cassette body 1. The fixing base plate 7 has a through hole 9. The retraction spring 8 is coaxial with the through hole 9. The support component 3 passes through the through groove 6 opened on the cassette body 1. The moving plate 10 has a connecting guide groove 17. The connecting guide groove 17 passes through the moving plate 10 vertically. The moving plate 10 is sleeved on the limiting component 2 through the connecting guide groove 17. The mounting rod 12 is fixedly installed in the connecting guide groove 17. The mounting rod 12 passes through both the retraction spring 8 and the through hole 9. The lead screw 13 on the fixing component 4 is rotatably installed in the mounting through groove 5 opened on the cassette body 1. The internal hexagonal column 14 is located in the cassette body. Inside the body 1, a threaded hole 16 is provided on the triangular pressing plate 15. The triangular pressing plate 15 is installed on the screw rod 13 through the threaded hole 16, and the upper end of the triangular pressing plate 15 contacts the upper inner wall of the main body 1. When rotating the screw rod 13, the force should be moderate to avoid excessive compression that could deform the rubber pad 11 or damage the wall. If it is necessary to disassemble the main body 1 of the dark box before filling the groove with cement mortar, a hex wrench can be used to rotate the screw rod 13 counterclockwise, so that the triangular pressing plate 15 moves forward. After the support component 3 loses the compression of the triangular pressing plate 15, it will be retracted into the main body 1 by the elastic force of the compression spring 8, thereby realizing the retraction of the support component 3 for easy adjustment or replacement.

[0022] In the support assembly 3, the inner end of the moving plate 10 (i.e. the side that contacts the triangular extrusion plate 15) is designed as an inclined structure, and its inclination angle matches the inclined surface of the triangular extrusion plate 15 to ensure that a smooth linear thrust transmission can be achieved when the two are in contact. A wear-resistant coating (such as polytetrafluoroethylene or hard anodized layer) can be added to the inclined surface to reduce frictional resistance and extend service life. The inclined surface of the inner end of the moving plate 10 and the inclined surface of the triangular extrusion plate 15 form a conjugate fit. When the lead screw 13 rotates, the inclined surface of the triangular extrusion plate 15 pushes the inclined surface of the moving plate 10 through sliding friction, thereby converting the rotational motion into the lateral linear motion of the support assembly 3.

[0023] Ultimately, by setting a limiting component 2, a supporting component 3, and a fixing component 4 inside the main body 1 of the junction box, the fixing component 4 can push the supporting component 3 outward, thereby causing the supporting component 3 to abut against the inner wall of the groove reserved in the main body 1 of the junction box, thus pre-fixing the main body 1 of the junction box. This design effectively solves the problem of displacement of the main body 1 of the junction box caused by uneven filling of cement mortar, long curing time, and shrinkage deformation in traditional processes, ensuring the stability and flatness of the main body 1 of the junction box, and avoiding deviations during subsequent modular panel installation. At the same time, the synergistic effect of the limiting component 2 and the supporting component 3 further enhances the anti-disturbance ability of the main body 1 of the junction box during construction, improves construction efficiency and quality, and reduces rework and material waste caused by improper installation. In addition, the limiting component 2 can limit the supporting component 3 during storage and transportation of the main body 1, so that the supporting component 3 is completely retracted into the main body 1 of the junction box, avoiding the need for the supporting component 3 to increase the storage and transportation space of the equipment, and avoiding structural damage or transportation safety hazards caused by the unexpected extension of the supporting component 3.

[0024] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
