Description

Technical Field

[0001] The invention belongs to the technical field of road crossing boxes, and in particular relates to a multi-angle road crossing bottom box. Background Art

[0002] During the construction of building installation projects, the laying of high-voltage pipelines usually requires buried pipes or exposed pipes to ensure the safety of the electromechanical installation process. When the pipeline is laid for a long time or encounters a turning position, a crossing box needs to be added to increase the convenience of threading. At present, the more common crossing boxes in the construction market are mostly square (75*75mm). While considering the unchanged safety, the flexibility and practicality of the crossing box are increased. The traditional square bottom box can only achieve a "straight" transition during the installation process. Due to the restrictions of the corner working conditions on site, the square bottom box needs to add a circular arc elbow for the laying pipe to use for transition when encountering a corner. The traditional square bottom box is mainly pre-buried and exposed, and these methods have the following defects: 1. The process of grooving the floor or wall of the pre-buried bottom box is relatively cumbersome. When encountering a corner position, it needs to be used with a circular arc elbow structure, which requires a large space, and the use of a smaller space is more limited; 2. The laying of pipelines in a small space consumes more labor and materials, increasing the construction cost.

[0003] A cylindrical multi-angle bottom box with a diameter of 75mm is proposed. By taking advantage of the cylindrical shape, the construction efficiency of the pre-embedded opening positioning of the bottom box is improved. When used with the corresponding circular opening water drill, the pre-embedded bottom box is simplified and the installation efficiency is greatly improved. In the process of laying open pipelines and encountering the working conditions of corner transition, the use of a circular 75 bottom box can achieve the angle conversion more quickly. When used in industrial style decoration or in a space without a ceiling, it also improves the aesthetics of the space to a certain extent. Summary of the invention

[0004] The purpose of the present invention is to provide a cylindrical multi-angle bottom box, which is provided with a movable threading tube and a fixed threading tube. The movable threading tube is rotated to realize the multi-angle passing bottom box with angle adjustment between the movable threading tube and the fixed threading tube.

[0005] The present invention is realized by the following measures: a multi-angle road bottom box, characterized in that it comprises a circular ring plate, a fan-shaped opening is opened on the side wall of the circular ring plate, a groove concentric with the circular ring plate is arranged on the upper and lower end surfaces of the fan-shaped opening, an adjustment plate concentric with the circular ring plate is slidably arranged in the groove, a movable threading tube is arranged at the center position of the adjustment plate, and a fixed threading tube is also arranged on the outer wall of the circular ring plate; The adjusting plate slides in the groove, and when the adjusting plate contacts one end wall of the groove, the movable threading tube and the fixed threading tube are perpendicular to each other, and when the adjusting plate contacts the other end wall of the groove, the axis of the movable threading tube coincides with the axis of the fixed threading tube.

[0006] Furthermore, it also includes a sealing plate detachably connected to either end of the circular ring plate. Generally, it is connected by threading, plugging or bolting. Alternatively, both ends of the circular ring plate may be provided with a connecting structure of the sealing plate. For example, threads are provided on the inner walls of both ends of the circular ring plate, and the sealing plate is connected to the circular ring plate by threading. In this way, the upper end and the lower end of the bottom box can be exchanged.

[0007] Furthermore, a fan-shaped fixing plate is provided on the adjustment plate and inside the side wall of the circular ring plate, and the upper and lower ends of the fan-shaped fixing plate both exceed the fan-shaped opening; the adjustment plate and the fan-shaped fixing plate are fixedly connected by a connecting column passing through the fan-shaped opening.

[0008] A fan-shaped channel is concentrically arranged in the fan-shaped fixed plate, and fan-shaped movable plates are concentrically arranged at both ends of the fan-shaped channel; Both ends of the fan-shaped channel are provided with locking screws capable of pressing against the fan-shaped movable plate through threaded connection; Furthermore, when the adjustment plates are respectively located at the two ends of the fan-shaped opening, the fan-shaped fixed plate and the two fan-shaped movable plates can cover the fan-shaped opening, so that the circular ring plate can be in a relatively sealed state.

[0009] Furthermore, guide pillars are fixedly provided on the inner wall of the circular ring plate and on both upper and lower sides of the outer end of the fan-shaped movable plate.

[0010] Furthermore, a limiting column of the fan-shaped movable plate is fixedly arranged on the outer side of the guide column. The limiting column can prevent the fan-shaped movable plate from being separated from the fan-shaped channel and prevent the fixed threading tube from being blocked.

[0011] Furthermore, a spring pin capable of pressing against the inner wall of the circular ring plate is provided on the outer wall of the sector-shaped fixing plate and below the sector-shaped opening.

[0012] Furthermore, blocking columns are fixedly arranged in the fan-shaped channel and on both sides of the movable threading tube, and the baffles can prevent the fan-shaped movable plate from sealing the movable threading tube.

[0013] Furthermore, the size of the circular ring plate can be determined according to actual conditions, and the outer diameter can be 75 mm.

[0014] Furthermore, ear plates may be reserved for installation on the outer wall of the circular ring plate according to actual conditions, and the ear plates are used to fix the bottom box to the floor wall with steel nails or expansion nails during later use.

[0015] Furthermore, the connection between the movable threading tube and the fixed threading tube and other wire tubes adopts existing technology, such as hot-melt connection.

[0016] Directions: When using the concealed method, use a drill of corresponding diameter to make a hole. In the part where the corner is required, lay out the line in advance. The adjustment plate can be rotated to make the movable threading tube and the fixed threading tube form an angle that meets the construction requirements (the adjustment angle range is between 90 degrees and 180 degrees). Adjust the position of the two fan-shaped movable plates to achieve the sealing of the fan-shaped opening, and then tighten the locking screws to fix it. The fan-shaped fixed plate can be positioned by the spring pin. At the same time, the adjusted bottom box can be used as an angle caliper to lay out the angle of the pipeline, and to a certain extent, it can also serve as a measuring tool for positioning and angle determination.

[0017] When exposed piping and wiring are used, steel nails or expansion nails are used to fix the base box to the floor wall; at the same time, when encountering a turn, it can self-adjust according to the angle requirements, and the pipelines and base box are arranged side by side and in parallel.

[0018] The beneficial effects brought about by the technical solution provided by the embodiment of the present invention are: simple structure, easy to mass produce, and low cost; easy and quick operation; the multi-angle crossing bottom box indirectly reduces the use of elbow joints during the open laying process; reduces the time for workers to process arc-shaped elbows by themselves, thereby improving the work efficiency of pipeline laying corner bending construction and reducing labor costs; in the process of open pipeline laying encountering working conditions where corner transition is required, the angle conversion process can be achieved more quickly by using the technical solution; it can be used in industrial style decoration or in spaces without suspended ceilings to improve the aesthetics of the space to a certain extent.
