[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a wearable fire hose reel, such as Figure 1-4 As shown, the device includes a waist belt 1, a connecting block 2 mounted on the upper left side of the waist belt 1, a shoulder strap 3 mounted on the upper end of the connecting block 2, a fixing plate 4 mounted on the left side of the waist belt 1, a positioning frame 5 rotatably mounted on the left side of the fixing plate 4, a nozzle 6 mounted on the inner side of the positioning frame 5, a handle 7 mounted on the upper end of the positioning frame 5, a bracket 8 mounted on the right side of the handle 7, a pressure rod 9 rotatably mounted on the outside of the bracket 8, a limit pin 10 mounted on the lower side of the pressure rod 9, and a limit groove adapted to the limit pin 10 is formed at an equal angle on the edge of the fixing plate 4. The limit pin 10 is inserted into the limit groove of the fixing plate 4. When using this device, the waist belt 1 can be worn around the user's waist, and the shoulder strap 3 can be placed on the shoulder away from the nozzle 6. Since the nozzle 6 and water pipe are relatively heavy, the shoulder strap 3 can distribute their weight and prevent waist strain. Excessive force on one side of the belt can cause discomfort when wearing it. A positioning frame 5 is installed on the side of the fixed plate 4, allowing adjustment of the spray angle of the nozzle 6 by pulling the handle 7 back and forth. A pressure rod 9 and a limiting pin 10 are provided; the limiting pin 10 engages with the limiting groove of the fixed plate 4 to limit the rotation of the positioning frame 5. When holding the handle 7, pressing the pressure rod 9 with your fingers will cause the limiting pin 10 to tilt upwards, disengaging it from the groove of the fixed plate 4, thus allowing for rotational adjustment of the positioning frame 5. After adjustment, the limiting pin 10 can be engaged with the corresponding limiting groove of the fixed plate 4. The cooperation between the limiting pin 10 and the fixed plate 4 achieves limiting and fixing after spray angle adjustment, making the device more convenient and labor-saving to use.

[0021] The bracket 8 consists of a column and a ring connected by bearings. The column is fixed to the side of the handle 7, while the pressure rod 9 is fixed to the outer wall of the ring. A spring 11 is installed between the column and the ring. With the spring 11, when the finger releases the pressure rod 9, the ring containing the pressure rod 9 returns to its original position under the action of the spring 11. This allows the limit pin 10 to automatically engage with the limit groove of the fixed plate 4, making the adjustment mechanism more convenient to use.

[0022] The lower side of the positioning frame 5 has a groove, and a pull rod 12 is slidably inserted into the groove. A locking block 13 is installed at the inner end of the pull rod 12. The outer wall of the nozzle 6 has a slot that matches the locking block 13. A limiting spring 14 is sleeved on the outside of the pull rod 12. With the locking block 13, the nozzle 6 is slidably inserted into the inner side of the positioning frame 5. The locking block 13 at the bottom of the positioning frame 5 is locked into the slot on the side wall of the nozzle 6 under the elastic force of the limiting spring 14, thereby realizing the limiting and fixing of the nozzle 6. This connection method makes the disassembly and assembly of the nozzle 6 more convenient and facilitates the subsequent replacement of different types of nozzles 6.

[0023] Both the waist belt 1 and the shoulder strap 3 are equipped with buckles 15 and have positioning grooves equidistantly spaced on their surfaces. The waist belt 1 and the shoulder strap 3 can be adjusted in length through the buckles 15, making it convenient for users of different body types to wear.

[0024] The connecting block 2 is rotatably installed on the upper end of the waist belt 1, and the shoulder strap 3 is installed on the movable end of the connecting block 2. By providing the connecting block 2, the rotating installation of the connecting block 2 allows the shoulder strap 3 to be rotated and adjusted, which makes it convenient for users of different heights to wear.

[0025] Both the waist belt 1 and the shoulder strap 3 are made of leather and have sponge pads on the inside. By placing sponge pads on the inside of the waist belt 1 and the shoulder strap 3, the pressure received by the skin can be cushioned, making it more comfortable to wear.
