Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering technology, and in particular to a rapid switching device for multi-circuit fire protection circuits. Background Technology

[0002] Modern buildings are becoming increasingly complex and multifunctional, such as large commercial complexes, high-rise buildings, and industrial plants. The fire protection systems in these places are large in scale, involving multiple areas and various types of fire protection equipment, requiring multi-circuit fire protection lines to connect and control the equipment.

[0003] In the traditional installation and maintenance of fire protection circuits, wiring connections are often made by tightening screws or welding. These methods are cumbersome and require professional tools and technicians to spend a lot of time to complete. Especially when connecting multiple circuits, the wiring workload is large and the efficiency is low, making it difficult to meet the needs of quickly setting up or adjusting fire protection circuits in emergency situations. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-circuit fire protection circuit quick-connection device. By pulling the lever, the plug plate is driven, and then the connector is inserted into the connector box. At this time, the lever is released, the first spring is released, and the slide plate bounces. The slide plate drives the rotating rod, and the rotating rod drives the plug plate to be inserted into the fixing hole and fixed. This ensures that the fire protection circuit always maintains a good electrical connection, enabling the fire protection equipment to operate stably at critical moments and reducing the probability of equipment failure due to circuit connection problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-circuit fire protection circuit quick-connection device includes: an adapter as the main connecting body, a plurality of connecting boxes fixedly connected to the right end of the adapter, pull rods slidably connected to both sides of the inner wall of the connecting boxes, a sliding plate fixedly connected to the opposite end of each pull rod, a rotating rod rotatably connected to the opposite end of each sliding plate, an insert plate rotatably connected to the opposite end of each rotating rod, a first spring provided between each sliding plate and the inner wall of the connecting box, a connector slidably connected to the inner wall of each connecting box, and a fixing component provided on the inner wall of each connecting box.

[0007] Furthermore, limiting plates are fixedly connected to both sides of the outer wall of the slide plate, and the outer walls of the limiting plates are slidably connected to the inner wall of the connecting box, and the outer walls of the insert plates are slidably connected to the inner wall of the connecting box.

[0008] Furthermore, one end of each of the first springs is connected to the slide plate, and the other end of each of the first springs is connected to the inner wall of the connecting box.

[0009] Furthermore, the inner wall of the connector is provided with multiple fixing holes corresponding to the insert plate.

[0010] Furthermore, the fixing assembly includes sliding grooves located on both sides of the inner wall of the connecting box. A slider is slidably connected to the outer wall of each sliding groove. A sliding rod is fixedly connected to the opposite end of each slider. A fixing cylinder is fixedly connected to the inner wall of each sliding rod. A movable plate is slidably connected to the inner wall of each fixed cylinder. An insert rod is fixedly connected to the inner wall of each movable plate. A second spring is provided between the inner walls of the fixed cylinder and the movable plate. A connecting plate is fixedly connected to the right end of each connecting head.

[0011] Furthermore, each of the connecting plates is fixedly connected to a fixing plate on its left end, and each fixing plate has an inclined groove on its inner wall, and each fixing plate has multiple insertion holes corresponding to the insertion rod on its inner wall.

[0012] Furthermore, one end of each of the second springs is connected to the movable plate, and the other end of each of the second springs is connected to the inner wall of the fixed cylinder.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by pulling the lever to drive the insert plate, and then inserting the connector into the connector box, the lever is released and the first spring is released to make the slide plate spring. The slide plate drives the rotating rod, and the rotating rod drives the insert plate to be inserted into the fixing hole and fixed. This ensures that the fire protection line always maintains a good electrical connection, so that the fire protection equipment can operate stably at critical moments and reduce the probability of equipment failure due to line connection problems.

[0015] 2. In this utility model, by pulling the sliding rod, it becomes tighter and tighter inside the inclined groove. When it reaches the tightest point, the insertion rod is released. At this time, the second spring will bounce the moving plate. The moving plate will drive the insertion rod to insert into the insertion hole and fix it, thereby preventing dust, powder and other impurities from entering the adapter and preventing dust from accumulating at the connection or on the internal components.

Detailed Implementation

[0023] 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.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a multi-circuit fire protection circuit quick-connection device, comprising: an adapter 1 as the main connecting body, multiple connecting boxes 2 fixedly connected to the right end of the adapter 1, pull rods 3 slidably connected to both sides of the inner wall of the connecting box 2, a sliding plate 4 fixedly connected to the opposite end of the pull rod 3, a rotating rod 5 rotatably connected to the opposite end of the sliding plate 4, an insert plate 6 rotatably connected to the opposite end of the rotating rod 5, a first spring 7 provided between the sliding plate 4 and the inner wall of the connecting box 2, a connector 8 slidably connected to the inner wall of the connecting box 2, a fixing component provided on the inner wall of the connecting box 2, a limiting plate 17 fixedly connected to both sides of the outer wall of the sliding plate 4, the outer wall of the limiting plate 17 slidably connected to the inner wall of the connecting box 2, the outer wall of the insert plate 6 slidably connected to the inner wall of the connecting box 2, one end of the first spring 7 connected to the sliding plate 4, the other end of the first spring 7 connected to the inner wall of the connecting box 2, and multiple fixing holes 9 provided on the inner wall of the connector 8 corresponding to the insert plate 6.

[0025] Specifically, multiple connection boxes 2 are provided on the adapter 1, which can simultaneously connect multiple fire protection lines from different sources. When installing the connector 8, first hold the pull rod 3 and pull it outward. The pull rod 3 will drive the insert plate 6 to move synchronously. Then, insert the connector 8 precisely into the connection box 2. When the connector 8 reaches the predetermined position, release the pull rod 3. At this time, the first spring 7 will quickly release its elasticity, pushing the slide plate 4 forward. As the slide plate 4 moves, it will drive the rotating rod 5 to move. The rotating rod 5 will then drive the insert plate 6 to be inserted into the fixing hole 9, completing the firm fixation. This design ensures that the electrical connection of the fire protection line is stable and reliable, allowing the fire protection equipment to operate normally in an emergency, and greatly reducing the risk of equipment failure caused by line connection failure. In addition, during the movement of the slide plate 4, the limit plate 17 will slide synchronously inside the connection box 2, providing guidance and support for the movement of the slide plate 4, effectively enhancing its stability during movement and ensuring the smoothness of the entire installation and fixing process.

[0026] Reference Figure 3 - Figure 5 The fixing assembly includes sliding grooves 13 located on both sides of the inner wall of the connecting box 2. Sliding blocks 14 are slidably connected to the outer walls of the sliding grooves 13. Sliding rods 15 are fixedly connected to the opposite ends of the sliding blocks 14. Fixing cylinders 16 are fixedly connected to the inner walls of the sliding rods 15. Moving plates 18 are slidably connected to the inner walls of the fixing cylinders 16. Insert rods 19 are fixedly connected to the inner walls of the moving plates 18. A second spring 20 is provided between the inner walls of the fixing cylinders 16 and the moving plates 18. A connecting plate 10 is fixedly connected to the right end of the connector 8. A fixing plate 11 is fixedly connected to the left end of the connecting plate 10. An inclined groove 12 is provided on the inner wall of the fixing plate 11. Multiple insertion holes 21 are provided on the inner wall of the fixing plate 11 corresponding to the insert rods 19. One end of the second spring 20 is connected to the moving plate 18, and the other end of the second spring 20 is connected to the inner wall of the fixing cylinder 16.

[0027] Specifically, when the installation operation reaches the predetermined position, the slide rod 15 will naturally embed into the inclined groove 12. At this time, the insertion rod 19 is manually pulled to cause it to shift, thereby causing the slide rod 15 to gradually tighten within the inclined groove 12. As the slide rod 15 moves in the inclined groove 12, the connection part is continuously tightened. When the slide rod 15 reaches the tightest position in the inclined groove 12, the insertion rod 19 is released, and the second spring 20 will immediately release its elastic potential energy, pushing the moving plate 18 to bounce quickly. The movement of the moving plate 18 causes the insertion rod 19 to be precisely inserted into the insertion hole 21, achieving a firm lock. Through this series of linkages, the device forms a tight sealed structure, effectively preventing dust, powder and other impurities from entering the interior of the adapter, avoiding the accumulation of impurities at the connection and on the surface of the components, thereby ensuring the stable electrical performance of the adapter and extending its service life.

[0028] Working principle: When installing connector 8, pulling rod 3 moves insert plate 6, then connector 8 is inserted into connector box 2. Once inserted, pull rod 3 is released. When pull rod 3 is released, first spring 7 springs slide plate 4, which in turn moves rotating rod 5. As rotating rod 5 moves, insert plate 6 is inserted into fixing hole 9 for fixation. This ensures that the fire protection circuit maintains a good electrical connection, allowing fire equipment to operate stably at critical moments and reducing the probability of equipment failure due to wiring connection problems. The movement of slide plate 4 also moves limit plate 1. 7. Sliding inside the connecting box 2, the limiting plate 17 improves the stability of the sliding plate 4 when it moves. When installed in place, the sliding rod 15 will be inserted into the inclined groove 12. When inserted, the insertion rod 19 is pulled to move it. At this time, the sliding rod 15 is pulled to make it tighter and tighter inside the inclined groove 12. When it reaches the tightest point, the insertion rod 19 is released. When the insertion rod 19 is released, the second spring 20 will bounce the moving plate 18. When the moving plate 18 is bounced, it drives the insertion rod 19 to be inserted into the insertion hole 21 for fixation. This can prevent dust, powder and other impurities from entering the adapter and prevent dust from accumulating at the connection or internal components.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
