Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically a fire truck hose reel device. Background Technology

[0002] The hose reel system on a fire truck is a crucial component of modern firefighting equipment. Its ingenious design ensures rapid and efficient deployment and retrieval of hoses. In the event of a fire, every second counts, and this system significantly reduces preparation time and improves firefighting efficiency. Hose reels are typically mounted on the side or rear of the fire truck and feature internal spring mechanisms or power-assisted systems that allow the hose to be quickly extended to the required length without tangling.

[0003] According to the search, patent document with publication number CN217187618U discloses a fire truck hose reel device, which includes two symmetrically arranged shielding discs and a limiting component detachably connected to the outer edge of the two shielding discs. The limiting component includes two symmetrically arranged fixing blocks detachably connected to the two shielding discs respectively and a U-shaped limiting baffle detachably arranged on one side of the two fixing blocks. The outer edge of the fixing block facing the U-shaped limiting baffle has an insert plate, and the insert plate facing the U-shaped limiting baffle has a magnetic slot centrally located.

[0004] The aforementioned comparative documents also have the following shortcomings: The aforementioned comparative documents mainly use magnetic suction mechanisms to facilitate the installation of the devices, but the most important reference for the use of fire-fighting equipment should focus on emergency response. Whether firefighters can quickly deploy the hoses in the reel and avoid hose tangling during fire-fighting and rescue operations should be of paramount importance. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model incorporates a rotatable and adjustable second limiting disc in conjunction with a first limiting disc to form a complete hose reel. When releasing the fire hose, the second limiting disc can be rotated to detach, allowing for rapid hose unwinding and avoiding the risk of hose tangling.

Detailed Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution:

[0024] Mounting bracket 1, a first limiting plate 2 is rotatably connected to the mounting bracket 1, a shaft seat is coaxially fixedly connected to one side of the first limiting plate 2, two arc-shaped limiting plates 4 are fixedly connected to the shaft seat, and a locking mechanism is provided on the shaft seat. The arc-shaped limiting plates 4 are made of plastic and have a certain degree of elasticity.

[0025] Bearing seat 5 is fixedly connected to mounting bracket 1. Limit seat 6 is rotatably connected to bearing seat 5. Two arc-shaped sliding plates 7 are fixedly connected inside limit seat 6. A second limit plate 8 is slidably connected between the two arc-shaped sliding plates 7. A snap-fit ​​plate 9 is fixedly connected to the axial center of the second limit plate 8. The arc-shaped sliding plates 7 allow the second limit plate 8 to rotate freely. Through the cooperation of bearing seat and limit seat 6, the second limit plate 8 can rotate a certain angle around bearing seat 5 as the axis.

[0026] The locking mechanism includes a mortgage housing 10 fixedly connected to a shaft seat and a mating block. Two rails are fixedly connected inside the mortgage housing 10, and a baffle plate 11 is slidably connected to the two rails. Two rotating seats are fixedly connected to one side of the baffle plate 11, and a support arm 12 is rotatably connected to each rotating seat. A bearing seat 5 is rotatably connected to the bottom of the mortgage housing 10, and a bidirectional threaded rod 13 is rotatably connected inside the bearing seat 5. Nuts 14 are threaded to both ends of the bidirectional threaded rod 13. The end of the support arm 12 away from the rotating seat is rotatably connected to the nut 14 on the corresponding side. A driven bevel gear 15 is coaxially fixedly connected to the bidirectional threaded rod 13. An adjusting knob 16 is rotatably connected to the mortgage housing 10. The adjusting knob 16's rotating shaft passes through the mortgage housing 10 and is coaxially fixedly connected to a driving bevel gear 3. The driving bevel gear 3 and the driven bevel gear 15 mesh with each other. When it is necessary to release the water hose, the adjustment knob 16 can be turned. When the adjustment knob 16 is turned, the driving bevel gear 3 will rotate, and the driven bevel gear 15 that meshes with it will also rotate. The bidirectional threaded rod 13, which is coaxially fixedly connected to the driven bevel gear 15, will rotate on the bearing seat 5. The two nuts 14 can move closer or further away from each other. When the two nuts 14 move further away from each other, the baffle plate 11 will slide a distance on the track and retract into the collateral housing 10. At this time, the second limit plate 8 can rotate a certain angle with the bearing seat 5 as the axis, thereby disengaging from the bearing seat. Firefighters can release the water hose quickly in a short time without tangling, saving valuable time for fire fighting and rescue operations.

[0027] The working principle of this utility model is as follows:

[0028] When the hose needs to be released, the adjustment knob 16 can be turned. When the adjustment knob 16 is turned, the driving bevel gear 3 will rotate, and the driven bevel gear 15 that meshes with it will also rotate. The bidirectional threaded rod 13, which is coaxially fixed to the driven bevel gear 15, will rotate on the bearing seat 5. The two nuts 14 can move closer or further apart. When the two nuts 14 move further apart, the baffle plate 11 will slide a distance on the track and retract into the collateral housing 10. At this time, the second limit plate 8 can rotate a certain angle with the bearing seat 5 as the axis, thereby disengaging from the bearing seat. Firefighters can release the hose quickly in a short time without tangling, saving valuable time for fire fighting and rescue operations.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
