Description

Technical Field

[0001] This utility model relates to the field of fire hose reel technology, and in particular to an integrated fire hose reel fixing shaft. Background Technology

[0002] Fire hose reel fixing shafts are a common component of firefighting equipment, primarily used to secure the rotating shaft of the fire hose reel. The fixing shaft ensures the stability and smooth operation of the fire hose reel, guaranteeing that firefighters can quickly and effectively deploy or retract the hose in an emergency.

[0003] The integrated fire hose reel fixing shaft disclosed in announcement number CN206642242U, although the fixing shaft body and hollow shaft of this utility model are integrally formed from aluminum alloy, and the connecting teeth and thread teeth are integrally formed without additional processing, the process is simpler, reducing production and processing costs and labor costs. At the same time, friction protrusions are integrally formed on the outer wall of the fixing shaft body, which increases the friction between it and the winding shaft sleeved on the fixing shaft body, which can effectively prevent the fixing shaft body from sliding left and right or rotating inside the winding shaft, effectively ensuring the normal use of the fire hose reel.

[0004] However, this integrated fire hose reel fixing shaft has the following disadvantages: it is not easy to improve the overall structural strength of the fixing shaft; the vibration pressure generated during the use of the fire hose reel can easily cause the fixing shaft to deform and bend, affecting its service life; in addition, it is not easy to install and disassemble the fire hose reel, and it is inconvenient for personnel to conduct regular inspections and maintenance. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides an integrated fire hose reel fixing shaft with the following advantages:

[0017] 1. This integrated fire hose reel fixing shaft, through the setting of limiting components and blocking plates, pulls two sets of sliding pins towards the center, causing the limiting strip to compress the spring, retracting the blocking plate, and thus installing the fire hose reel body onto the integrated fixing shaft body. When the sliding pins are released, the spring drives the limiting strip to reset, causing the blocking plate to extend and limit the fire hose reel body, achieving the effect of facilitating the installation and disassembly of the fire hose reel body, and facilitating regular inspection and maintenance.

[0018] 2. The integrated fire hose reel fixing shaft is reinforced with ribs and strengthening components. The ribs improve the overall strength of the integrated fixing shaft, while the horizontal and vertical ribs enhance its load-bearing capacity.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 5This utility model provides a technical solution: an integrated fire hose reel fixing shaft, including an integrated fixing shaft body 1. The inner wall of the integrated fixing shaft body 1 has four sets of cavities arranged in a ring array. Reinforcing ribs 2 are fixedly arranged inside the cavities. Two sets of reinforcing components 3 are fixedly arranged inside the integrated fixing shaft body 1. Through the setting of reinforcing ribs 2 and reinforcing components 3, the reinforcing ribs 2 improve the overall strength of the integrated fixing shaft body 1, and the reinforcing horizontal ribs 301 and reinforcing vertical ribs 302 improve the pressure bearing capacity of the integrated fixing shaft body 1. The vibration generated by the fire hose reel body 8 during use is less likely to cause the integrated fixing shaft body 1 to deform and bend, thus extending its service life.

[0028] A positioning frame 4 is fixedly installed on one side of the inner wall of the integrated fixed shaft 1. A limit component 5 is slidably installed on the surface of the positioning frame 4. A blocking plate 6 is fixedly installed at one end of the limit component 5. By setting the limit component 5 and the blocking plate 6, two sets of sliding pins 501 are pulled towards the center, so that the limit bar 503 squeezes the spring 502, retracting the blocking plate 6, thereby installing the fire hose reel body 8 onto the integrated fixed shaft 1. When the sliding pins 501 are released, the spring 502 drives the limit bar 503 to reset, so that the blocking plate 6 extends to limit the fire hose reel body 8, achieving the effect of facilitating the installation and disassembly of the fire hose reel body 8, and facilitating regular inspection and maintenance.

[0029] A braking mechanism 7 is fixedly installed on one side of the surface of the integrated fixed shaft 1. With the setting of the braking mechanism 7, the fire hose reel 8 will rotate as the fire hose is taken out during use. Opening the hydraulic rod 701 will drive the brake pad 702 and the anti-slip pad 9 to slightly resist the fire hose reel 8, control the speed, and avoid loss of control due to inertia. The fire hose reel 8 is sleeved on the surface of the integrated fixed shaft 1.

[0030] The reinforcing component 3 includes a reinforcing horizontal rib 301 and a reinforcing vertical rib 302. The reinforcing horizontal rib 301 is fixedly disposed on the surface of the reinforcing vertical rib 302, and both ends of the reinforcing horizontal rib 301 and the reinforcing vertical rib 302 are fixedly disposed on the inner wall of the integral fixed shaft 1.

[0031] By setting the reinforcing component 3, the reinforcing rib 2 improves the overall strength of the integrated fixed shaft 1, and the reinforcing horizontal rib 301 and the reinforcing vertical rib 302 improve the bearing capacity of the integrated fixed shaft 1.

[0032] The limiting component 5 includes a sliding pin 501, a spring 502, and a limiting strip 503. The sliding pin 501 is slidably disposed on the surface of the positioning frame 4, the limiting strip 503 is fixedly disposed on the surface of the sliding pin 501, one end of the spring 502 is fixedly disposed on the surface of the limiting strip 503, and the other end of the spring 502 is fixedly connected to the positioning frame 4.

[0033] The limiting component 5 is designed to extend and retract the blocking plate 6.

[0034] The braking mechanism 7 includes a hydraulic rod 701 and a brake pad 702. The hydraulic rod 701 is fixedly installed on one side of the surface of the integral fixed shaft 1, and the brake pad 702 is fixedly installed at the output end of the hydraulic rod 701.

[0035] By setting the braking mechanism 7, the hydraulic rod 701 is opened, which drives the brake pad 702 and the anti-slip pad 9 to slightly resist the fire hose reel body 8, control the speed, and avoid loss of control due to inertia.

[0036] An anti-slip plate 9 is fixedly installed on one side of the brake pad 702. The anti-slip plate 9 is made of rubber.

[0037] The anti-slip pad 9 increases friction.

[0038] Two sets of through slots are provided on the side of the integrated fixed shaft 1 near the positioning frame 4, and the blocking plate 6 is slidably disposed inside the through slots.

[0039] The through-slot facilitates the penetration of the blocking piece 6.

[0040] There are four sets of reinforcing ribs 2, which are arranged in a ring array. Limiting grooves are opened on both sides of the inner wall of the positioning frame 4, and the limiting strip 503 is slidably set inside the limiting groove.

[0041] The limit groove serves to limit the movement of the limit strip 503.

[0042] In this invention, the working steps of the device are as follows:

[0043] First step: The reinforcing rib 2 improves the overall strength of the integrated fixed shaft 1, and the reinforcing horizontal rib 301 and the reinforcing vertical rib 302 improve the pressure bearing capacity of the integrated fixed shaft 1. The vibration generated by the fire hose reel body 8 during use is less likely to cause the integrated fixed shaft 1 to deform or bend, thus extending its service life.

[0044] The second step: Pull the two sets of sliding pins 501 toward the center, so that the limiting strip 503 squeezes the spring 502, retracts the blocking plate 6, and then installs the fire hose reel body 8 onto the integrated fixed shaft body 1. Release the sliding pins 501, and the spring 502 drives the limiting strip 503 to reset, so that the blocking plate 6 extends to limit the fire hose reel body 8, which facilitates the installation and disassembly of the fire hose reel body 8 and facilitates regular inspection and maintenance.

[0045] Third step: When in use, as the fire hose is taken out, the fire hose reel body 8 will rotate. Open the hydraulic rod 701, which will cause the brake pad 702 and anti-slip pad 9 to slightly resist the fire hose reel body 8, control the speed, and avoid loss of control due to inertia.
