Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this embodiment, as Figure 1 and Figure 2 As shown, a quick-release hose reel device includes: a hose reel 1 with two insertion ports 11; a hose release assembly 2 capable of quickly separating the coiled hose from the hose reel 1 to accelerate the deployment of the hose to the fire scene; and an auxiliary separation assembly 3 used to deflect the hose release assembly 2 to assist it in separating the hose from the hose reel 1.

[0049] The hose release assembly 2 includes: two winding rods 22, which are used to wind up the hose; one end of the two winding rods 22 extends into two insertion ports 11; and the other end of the two winding rods 22 is connected to a baffle 21, which is used to prevent the hose from falling off from the end of the winding rod 22 away from the hose reel 1.

[0050] Both insertion ports 11 are equipped with magnets 11a, which are magnetically connected to the winding rod 22.

[0051] Therefore, the end of the winding rod 22 away from the baffle 21 is inserted into the insertion interface 11 of the hose reel 1. The winding rod 22 and the magnet 11a in the insertion interface 11 are magnetically attracted together. Then, the fire hose is folded in half and wound between the two winding rods 22. When the fire hose needs to be used, the winding rod 22 is pulled to separate from the insertion interface 11. The fire hose and the winding rod 22 are separated from the hose reel 1. Then, the two joints of the fire hose are held and the rolled fire hose is vigorously swung. As the fire hose rolls out, the winding rod 22 separates from the fire hose, so that the fire hose can be used.

[0052] Specifically, the hose reel 1 and the baffle 21 are symmetrically distributed based on the winding rod 22. There are two winding rods 22, and the outer diameter of the winding rod 22 is adapted to the inner diameter of the insertion interface 11. The magnet 11a is used to magnetically attract the winding rod 22.

[0053] like Figure 6 As shown, the fire hose is folded in half and wrapped around the outer wall of a winding rod 22. Then, using the wrapped winding rod 22 as the base point, the overlapping hoses are wrapped around the outer periphery of another winding rod 22 and returned to the wrapped winding rod 22 to perform initial winding between the fire hose and the winding rod 22.

[0054] In some embodiments, such as Figure 1 and Figure 3 As shown, the auxiliary separation assembly 3 includes: a support plate 31, the top end of which is connected to the hose reel 1 via a first pin 311; a drag base 32, which is connected to the bottom end of the support plate 31 via a second pin 321; and a locking member 33, which is used to lock the position of the support plate 31 in the drag base 32.

[0055] Specifically, a groove adapted to the width of the bearing plate 31 is machined in the towing base 32. When the bearing plate 31 and the towing base 32 are perpendicular, the hose reel 1 is rotated by the first pin 311 to wind up the fire hose. At this time, under the action of the magnet 11a and the insertion of the winding rod 22 into the insertion interface 11, the winding rod 22 can rotate with the hose reel 1.

[0056] When the bearing plate 31 is rotated into the groove of the drag base 32 by the second pin 321, the bearing plate 31 is parallel to the ground. Under the gravity of the fire hose, the baffle 21 and the winding rod 22 are separated from the hose reel 1. (In addition, if the winding rod 22 is not separated from the hose reel 1, applying a downward force to the baffle 21 by hand or foot can separate the winding rod 22 from the hose reel 1.)

[0057] In some embodiments, such as Figure 5 As shown, the locking component 33 includes: a fixed base 331, the bottom end of which is connected to the drag base 32; a locking plate 332, the bottom end of which is hinged to the fixed base 331, and a wedge block 332a is disposed in the locking plate 332, the wedge block 332a being adapted to the slot of the bearing plate 31; and a torsion spring 333, a crossbar 333a is inserted into the torsion spring 333, both ends of which are connected to the fixed base 331, one end of the torsion spring 333 abutting against the locking plate 332, and the other end of the torsion spring 333 abutting against the fixed base 331.

[0058] Specifically, the clamping plate 332 is hinged to the fixing seat 331 by a locking pin. A groove adapted to the wedge block 332a is machined on the outer wall of the bearing plate 31. The torsion spring 333 is used to apply external force to the clamping plate 332 so that the wedge block 332a can enter the groove of the bearing plate 31. The crossbar 333a is used to constrain the installation position of the torsion spring 333. When the wedge block 332a enters the groove of the bearing plate 31, the bearing plate 31 and the drag base 32 are in a perpendicular state. When the wedge block 332a separates from the bearing plate 31, the bearing plate 31 can rotate and enter the groove of the drag base 32.

[0059] In some embodiments, such as Figure 2 As shown, the input end of the first pin 311 is equipped with a connecting plate 312, and the end of the connecting plate 312 away from the first pin 311 is equipped with a drive handle 313.

[0060] Specifically, the first pin 311 is used to drive the hose reel 1 to rotate, and the connecting plate 312 is used to connect the drive handle 313 to the first pin 311. The outer periphery of the drive handle 313 is machined with anti-slip texture.

[0061] In addition, an electric motor can also be used as the power source to drive the first pin 311 to rotate.

[0062] In some embodiments, such as Figure 7 As shown, the bearing plate 31 is equipped with a clamping member 4; the clamping member 4 includes: a mounting plate 41, one end of which is connected to the bearing plate 31, and the other end of which is rotatably connected to a guide roller 42; and a clamping roller 43, which is arranged parallel to the guide roller 42, and is connected to the mounting plate 41 through a sliding member 44.

[0063] Specifically, the mounting plate 41 is located diagonally below the bearing plate 31. The purpose of this design is to allow water remaining in the fire hose to be discharged when the fire hose is wound along the guide roller 42. The clamping roller 43 cooperates with the guide roller 42 to fix the joints at both ends of the fire hose.

[0064] In some embodiments, such as Figure 7 As shown, the sliding member 44 includes: a sliding shell 441, the bottom end of which is connected to the mounting plate 41, a slider 442 slidably connected in the sliding shell 441, the slider 442 being hinged to the clamping roller 43; a guide rod 443, the outer periphery of which is inserted into the sliding shell 441, the bottom end of which is connected to the slider 442; and an elastic member 444, which is sleeved and connected to the guide rod 443, and is located between the sliding shell 441 and the slider 442.

[0065] Specifically, a groove is machined in the sliding shell 441, the slider 442 can move up and down in the sliding shell 441, the clamping roller 43 can rotate in the slider 442, the guide rod 443 is used to constrain the movement direction of the slider 442, and the elastic element 444 is used to apply downward pressure to the slider 442.

[0066] In some embodiments, such as Figure 7 As shown, elastic element 444 is a compression spring;

[0067] Specifically, the elastic element 444 adopts a compression spring design, which facilitates pushing the slider 442 to reset in the sliding shell 441.

[0068] In some embodiments, such as Figure 1 and Figure 4 As shown, a movable component 5 is provided at the bottom of the towing base 32; the movable component 5 includes: a linkage shaft 51, which is connected to the towing base 32 via bearings, and rollers 52 are provided at both ends of the linkage shaft 51; and a caster wheel 53, which is used to change the travel direction of the towing base 32, and the caster wheel 53 is located on the side of the towing base 32 away from the linkage shaft 51.

[0069] Specifically, both ends of the linkage shaft 51 are equipped with rollers 52, and there are two universal wheels 53. The bottom of the universal wheel 53 and the bottom of the roller 52 are located on the same horizontal plane, thereby driving the overall mechanism to move.

[0070] The working principle of this application is illustrated below with a preferred embodiment:

[0071] When the support plate 31 and the drag base 32 are in a vertical position, insert the end of the winding rod 22 away from the baffle 21 into the insertion interface 11 of the hose reel 1. The winding rod 22 is magnetically attracted to the magnet 11a. Then, fold the fire hose in half and perform initial winding between the two winding rods 22. (Refer to...) Figure 6 Understand the winding method of the fire hose and the two winding rods 22. Other winding methods can also be used as long as the fire hose can be initially fixed on the winding rods 22. Rotate the drive handle 313 to drive the first pin 311 to rotate through the connecting plate 312. Then the first pin 311 drives the hose reel 1 to rotate in order to wind up the fire hose.

[0072] During the winding process, the fire hose moves along the outer wall of the guide roller 42. After winding is completed, the guide rod 443 moves upward in the sliding shell 441. The guide rod 443 drives the slider 442 to move upward and compresses the elastic element 444. Then, the fire hose is clamped between the guide roller 42 and the clamping roller 43. Under the action of the elastic element 444, the joint of the fire hose is clamped to prevent the joint of the fire hose from shaking back and forth during transportation.

[0073] When it is necessary to disassemble the fire hose wound between the hose reel 1 and the baffle 21, rotate the clamping plate 332 in the fixing seat 331. At the same time, the clamping plate 332 causes the wedge block 332a to separate from the bearing plate 31, and the clamping plate 332 squeezes the torsion spring 333 on the outer periphery of the crossbar 333a to deform. Then, the bearing plate 31 is flipped through the second pin 321. When the bearing plate 31 is flipped into the groove of the drag base 32, the two winding rods 22 and the baffle 21 are separated from the hose reel 1 under the action of the fire hose's own weight. Then, hold the two joints of the fire hose and swing the rolled fire hose forcefully. At the same time, the winding rods 22 separate from the fire hose.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
