Description

Technical Field

[0001] This utility model relates to the field of pre-embedded junction box assembly technology, specifically a positioning and fixing device for pre-embedded junction boxes that are on the same plane as the outer surface of shear walls. Background Technology

[0002] As is well known, in building construction, embedded junction boxes are an important component of electrical installation. Their accurate positioning and stable fixing are crucial for ensuring the normal operation of the entire building's electrical system. Traditional methods for installing embedded junction boxes mainly involve manual measurement, marking, and fixing them to the reinforcing steel structure using wire or similar tools. However, with the increasing complexity of modern building structures, especially the widespread application of shear wall structures, these traditional methods have gradually exposed a series of problems. In terms of positioning accuracy, traditional methods rely on manual measurement and marking, which are easily affected by human factors, leading to significant deviations in the position of the embedded junction boxes. Especially during shear wall construction, the dense reinforcement inside the wall increases the difficulty of accurately positioning the embedded junction boxes. If the position of the embedded junction box is inaccurate, it will directly affect the installation quality of subsequent electrical equipment and may even require complex repair work, thereby increasing costs and time. In addition, existing embedded junction box positioning devices lack versatility and flexibility, making it difficult to adapt to the needs of junction boxes of different shapes and sizes. Moreover, most existing devices are not reusable and are discarded after one positioning operation, which not only increases material costs but also contradicts the concept of green and environmentally friendly buildings. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a positioning and fixing device for the pre-embedded junction box to be on the same plane as the outer surface of the shear wall, which has the following advantages:

[0014] The positioning and fixing device for the embedded junction box, which is flush with the outer surface of the shear wall, can quickly and accurately locate the position of the embedded junction box by setting laser emitters on the four sides of the positioning box. Construction personnel can adjust the position of the positioning box according to actual needs and use the beam emitted by the laser emitter to determine the specific installation position of the embedded junction box, ensuring that it is on the same plane as the outer surface of the shear wall, which greatly improves the accuracy of positioning. The embedded junction box is equipped with hooks on the four sides, which can be easily and firmly tied to the steel bars before the shear wall is processed with steel wire, preventing displacement or tilting during the concrete pouring process and ensuring the stability of the embedded junction box.

[0015] The use of threaded posts and conical fasteners simplifies the installation and removal of the positioning box. Simply rotating the threaded post completes the fixing or removal of the positioning box, eliminating the need for complex tools and procedures, thus significantly saving construction time. It also allows for quick removal of the positioning box for reuse, reducing costs. The entire positioning and fixing process is simple and intuitive, reducing time spent on manual measurement and marking, and improving work efficiency. Furthermore, the energy storage mechanism powering the laser emitter avoids dependence on external power sources, increasing on-site safety and flexibility. Since the positioning box can be reused multiple times, material waste is reduced, which not only helps lower the overall project cost but also promotes the efficient use of resources.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-4This utility model is a positioning and fixing device for a pre-embedded junction box that is flush with the outer surface of a shear wall. It includes a pre-embedded junction box body 1 and a positioning box 2. Hooks 3 are provided on all four outer walls of the pre-embedded junction box body 1. Inclined blocks 4 and laser emitters 5 are provided on all four outer walls of the positioning box 2. A power storage mechanism is provided on the positioning box 2. A threaded hole is provided at one end of the positioning box 2, and a threaded post 6 is provided on the threaded hole. A fastening groove is provided at one end of the threaded hole. A fastening hole is provided between one end of the inclined block 4 and the fastening groove. A fastening post 7 is provided on the fastening hole. The fastening post 7 has inclined grooves at both ends. A limiting plate 8 is provided between one end of the fastening post 7 and the fastening groove. A cone 9 is provided between one end of the threaded post 6 and the fastening groove. In this embodiment, the operator places the positioning box 2 against the inner wall of the pre-embedded wire box body 1, and then rotates the threaded post 6. The threaded post 6 rotates and moves within the threaded hole, thereby causing the threaded post 6 to drive the cone 9 to rotate and move. The cone 9 contacts the inclined grooves of the fastening post 7 in the four fastening holes and moves linearly. The fastening post 7 abuts against the pre-embedded wire box body 1. One side of the inner wall of the junction box body 1 is secured by four fastening posts 7, thereby fixing the positioning box 2 onto the junction box body 1. Then, the power supply mechanism powers the laser emitter 5. By activating the laser emitter 5, a laser can be emitted to one side of the junction box body 1. The laser emitter 5 is a common type of laser emitter with built-in button function in the prior art, which will not be described in detail in this structure. With the laser emitter 5 set on the four sides of the positioning box 2, it is easy for personnel to rotate the corresponding side to activate the laser emitter 5 according to the positioning requirements, thereby facilitating the quick positioning of the junction box body 1. Then, through the four hooks 3 on the outer wall of the junction box body 1, personnel use steel wire to tie it to the steel bars before shear wall processing, thereby positioning and fixing the junction box body 1. Then, by rotating the threaded post 6 in the opposite direction, the cone head 9 can be disengaged from the fastening post 7. The limiting plate 8 can prevent the fastening post 7 from leaving the fastening hole, so the positioning box 2 can be quickly removed, facilitating the positioning and fixing of other junction box bodies 1.

[0023] To facilitate power supply to the laser emitters 5, in this design, the energy storage mechanism includes a battery slot, which is located at one end of the positioning box 2. A battery box 10 is provided on the battery slot, and a battery cover 11 is provided between the battery slot and the positioning box 2. The battery cover 11 is snapped into the battery slot. By opening the battery cover 11, the battery box 10 in the battery slot can supply power to the four laser emitters 5. The battery cover 11 is then snapped into the battery slot to secure and seal the battery box 10.

[0024] In order to facilitate more stable compression of the fastening column 7 by the cone head 9, in this solution, the angle of the inclined groove of the fastening column 7 is 30°-45°, and the cone head 9 is a conical metal column with a cone angle of 60°, which allows the cone head 9 to contact and abut against the inclined groove of the fastening column 7, thereby making the fastening column 7 more firmly abut against the inner wall of the pre-embedded junction box body 1.

[0025] In order to improve the sealing between the battery cover 11 and the battery compartment, in this solution, a sealing ring is provided on the contact surface between the battery cover 11 and the battery compartment. The sealing ring can improve the sealing between the battery cover 11 and the battery compartment.

[0026] In order to improve the stability of the fastening post 7 against the inner wall of the pre-embedded junction box body 1, in this solution, a rubber pad is provided at one end of the fastening post 7. The rubber pad can improve the stability of the fastening post 7 against the inner wall of the pre-embedded junction box body 1, so that the positioning box 2 is more securely assembled on the pre-embedded junction box body 1.

[0027] In order to make the fastening post 7 move more stably in a straight line in the fastening hole, in this solution, the fastening post 7 is adapted to the fastening hole. By adapting the size of the fastening post 7 to the fastening hole, the fastening post 7 can move more stably in a straight line in the fastening hole.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
