Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically a flexible telescopic wire harness storage mechanism for a fire-fighting mobile power supply box. Background Technology

[0002] In firefighting operations, portable power supply boxes play a crucial role. They provide power to various firefighting equipment, such as lighting fixtures, communication devices, and electric breaching tools, ensuring firefighters have a reliable energy supply during missions. However, with the increasing diversity and complexity of firefighting needs, some issues related to wiring harness management have emerged during the use of portable power supply boxes. These issues have adversely affected the ease of use, safety, and overall performance of the equipment.

[0003] Currently, fire-fighting mobile power supply boxes have significant shortcomings in terms of cable management.

[0004] 1. Most power boxes lack effective cable management mechanisms, and wires are usually haphazardly tangled inside or outside the box, resulting in messy and disorganized wiring. This not only takes up space but also increases the difficulty for firefighters to connect and disconnect equipment during emergency operations, potentially delaying rescue efforts.

[0005] 2. While some existing storage mechanisms utilize elastic components such as torsion springs for resetting, these components are prone to deformation after prolonged use, affecting resetting performance. Furthermore, these elastic components generate significant bursts of elastic force during winding, resulting in excessively fast resetting speeds that can easily injure electrical wires and operators.

[0006] Therefore, there is an urgent need for a wire harness storage mechanism that can maintain good reset performance even after long-term use, and whose winding and reset process is slow and will not cause damage to the wires or operators. Utility Model Content

[0031] Please see Figure 1-6 This embodiment provides a flexible telescopic wire harness storage mechanism for a fire-fighting mobile power supply box, used to store the wires 2 on the power supply box 1, one end of which is connected to the power supply system inside the power supply box 1.

[0032] An electric slip ring 5 is mounted on the power supply box 1 via a mounting shaft 3. The mounting shaft 3 is fixed to the power supply box 1 by screws or welding. The fixed end of the electric slip ring 5 is connected to the power supply box 1 via a wire 22. The wire 22 is used to energize the electric slip ring. A winding wheel 4 is rotatably mounted on the mounting shaft 3. The wire 2 is wound around the winding wheel 4. One end of the wire 2 is connected to the rotating movable end of the electric slip ring 5. The connection between the wire 2 and the rotating movable end of the electric slip ring 5 can be made by welding or crimping to ensure the stability of power transmission.

[0033] A gear 6 is provided on the winding reel 4, located on the side of the winding reel 4 closest to the power supply box 1. The gear 6 is movably sleeved with the mounting shaft 3, ensuring that the gear 6 can rotate synchronously with the winding reel 4. The gear 6 is sleeved on the mounting shaft 3 but not connected to it. A sleeve 9 is provided on the power supply box 1, which is installed on the side wall of the power supply box 1 by welding. A piston rod 8 is movably inserted into the sleeve 9, and a rack 7 is connected to the piston rod 8. The rack 7 moves with the piston rod 8 and meshes with the gear 6.

[0034] like Figure 3 , 4 As shown in Figure 5, when the worker needs to pull out the wire 2, he holds the end of the wire 2 and pulls it outward. At this time, the gear 6 rotates forward and meshes with the rack 7, pushing the piston rod 8 welded to the rack 7 into the sleeve 9. During the process of pushing the piston rod 8 in, the air in the sleeve 9 is compressed. When the wire 2 is put away after use, the worker only needs to let go, and the air in the sleeve 9 is released, which slowly pushes out the piston rod 8 and drives the rack 7 to return to its original position. At this time, the gear 6 meshing with the rack 7 is pushed in reverse by the teeth of the rack 7, which drives the winding wheel 4 to rotate in reverse at the same time, thereby realizing the reset and storage of the pulled-out wire 2.

[0035] In some embodiments, the winding wheel 4 is provided with a baffle 10. The baffle 10 is made of a rubber material with a certain elasticity and is semi-arc in shape. The shape of the baffle 10 matches the outer ring of the winding wheel 4 and is installed on the outer ring of the winding wheel 4 by adhesive, in order to prevent the wound wire from detaching from the winding wheel 4.

[0036] like Figure 5 As shown, when pulling the wire 2 outward, the angle of pulling is not fixed, which may cause the entire coil of wire 2 to slip to the side of the winding wheel 4, thus causing the entire coil of wire 2 to fall off the winding wheel 4. Therefore, a semi-circular baffle 10 is used to cover part of the outer ring of the winding wheel 4 to prevent the winding wheel 4 from falling off.

[0037] In some embodiments, the slip ring 5 is provided with a mounting block 111, which is fixed to the outward side of the slip ring 5 by welding. The mounting block 111 is provided with a connecting rod 11, and a first guide block 12 is slidably connected to the connecting rod 11, and the first guide block 12 can slide left and right on the connecting rod 11. One side of the first guide block 12 is provided with an insertion rod 14, which is cylindrical, smooth, and has a certain degree of elasticity. The diameter of the insertion rod 14 is slightly smaller than the diameter of the corresponding snap-fit ​​hole on the second guide block 13. The first guide block 12 snaps into the second guide block 13 via the insertion rod 14, and the first guide block 12 and the second guide block 13 enclose the wire 2. The second guide block 13 has a snap-fit ​​hole that matches the insertion rod 14, and the inner wall of the snap-fit ​​hole has an annular groove. During installation, align the first guide block 12 and the second guide block 13 with the wire 2, so that the wire 2 is within the space formed by the first guide block 12 and the second guide block 13. Then, insert the plug 14 on the first guide block 12 into the snap-fit ​​hole of the second guide block 13. The end of the plug 14 will slightly deform due to elasticity and enter the snap-fit ​​hole and snap into the annular groove, thereby achieving the snap-fit ​​between the first guide block 12 and the second guide block 13, thus covering the wire 2 and playing a stable guiding role in the direction and position of the wire 2, preventing the wire 2 from shifting or getting tangled during storage or use.

[0038] In some embodiments, the insertion rod 14 is made of magnet material, and the second guide block 13 is made of iron. The insertion rod 14 is made of magnet material with a smooth surface and magnetic properties. During installation, the first guide block 12 and the second guide block 13 are aligned with the wire 2 so that the wire 2 is in the space between them. Then the insertion rod 14 is brought close to the second guide block 13. The insertion rod 14 is connected by magnetic attraction, which covers the wire 2 to stably guide its direction and position, and prevents it from shifting or getting tangled when stored or used.

[0039] In some embodiments, each mounting block 111 is rotatably connected to the connecting rod 11. This rotatable connection design allows the wire 2 to have more room to move during the pulling or winding process, effectively avoiding the wire 2 from being stuck at the first guide block 12 and the second guide block 13 due to the pulling angle, thereby preventing the outer sheath of the wire 2 from wrinkling.

[0040] In some embodiments, a protective sleeve 21 is provided on the side wall of the power box 1 near the winding wheel 4. The protective sleeve 21 is made of rubber and is installed on the side wall of the power box 1 by adhesive. One end of the wire 2 near the first guide block 12 is inserted into the protective sleeve 21. After using the wire 2, the connector end of the wire 2 is inserted into the protective sleeve 21 to prevent damage to the connector end of the wire 2 due to special weather or other external reasons.

[0041] In some embodiments, the power supply box 1 is provided with a shoulder strap 15, which is made of elastic material. During transportation, the power supply box 1 is carried on the back by the shoulder strap 15 for convenient handling.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
