All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention. The following details the embodiments of the present invention with reference to the accompanying drawings:

[0043] In the description of the present invention, it should be understood that unless otherwise specified, the meaning of "a plurality of" is two or more; the terms "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the scope of protection of the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] Such as Figure 1 、 2As shown, the fire hose support includes a vertical rod assembly, an adjustable mounting base 1, a three-legged support assembly, and a buckle assembly 20. Among them, the vertical rod assembly includes a fixed vertical rod 4 and a telescopic rod 2 that can be relatively telescoped and rotated. The telescopic rod 2 is sleeved on the fixed vertical rod 4 through a vertical rod locking nut 3 and locked to the fixed vertical rod 4 to limit and fix the two. Specifically, the telescopic rod 2 extends into the fixed vertical rod 4 from top to bottom, and the two are in clearance fit. The relative position of the telescopic rod 2 and the fixed vertical rod 4 is adjusted telescopically to adjust the overall height of the vertical rod assembly, and it is locked by the vertical rod locking nut 3. The locking method of the vertical rod locking nut 3 can be that the vertical rod locking nut 3 has an internal thread, the upper end of the fixed vertical rod 4 has an external thread, the vertical rod locking nut 3 is sleeved outside the telescopic rod 2, and is locked to the fixed vertical rod 4 through threaded connection. When the vertical rod locking nut 3 is tightened on the fixed vertical rod 4, the vertical rod locking nut 3 will exert a radial pressure on the telescopic rod 2, such as through a conical surface, a rubber pad or a friction plate, so that it is in close contact with the outer wall of the telescopic rod 2 and is threadedly connected to the fixed vertical rod 4, preventing the telescopic rod 2 and the fixed vertical rod 4 from rotating and telescoping relative to each other. When the vertical rod locking nut 3 is not locked, the telescopic rod 2 is placed at the lowest position, and the telescopic rod 2 can rotate relative to the fixed vertical rod 4 to realize remote adjustment of the horizontal angle of the fire hose by moving the fire hose connected to the fire hose.

[0045] As Figure 4As shown in the figure, the adjustable mounting base 1 is arranged at the top of the telescopic rod 2 and is used to mount the fire hose and adjust its pitching angle. The adjustable mounting base 1 includes a base 11, a U-shaped mounting plate 14 and a buckle 15. The base 11 is fixed to the top of the telescopic rod 2. Specifically, a connecting piece is arranged below the base 11 and inserted into the telescopic rod 2 and locked by screws. The U-shaped mounting plate 14 is used to support the fire hose. One end of it is hinged to the upper part of the base 11, and the other end is connected to the lower part of the base 11 through an arc-shaped adjusting plate 18 to adjust the pitching angle of the U-shaped mounting plate 14 and the fire hose. Specifically, the base 11 is a symmetrical triangular base. One end of the U-shaped mounting plate 14 is hinged by a shaft between the upper end corners of the two triangles of the symmetrical triangular base and can be locked by a second locking screw 13. One end of the arc-shaped adjusting plate 18 is fixedly connected to the other end of the U-shaped mounting plate 14. The other end of the arc-shaped adjusting plate 18 has an arc-shaped groove. Another shaft passes through the arc-shaped groove and is connected to the lower end corner of one side triangle of the symmetrical triangular base. The U-shaped mounting plate 14 can rotate around the shaft along the arc-shaped groove to adjust the pitching angle and can be locked by a first locking screw 12. The arc-shaped adjusting plate 18 can also be symmetrically connected to the two triangles of the symmetrical triangular base. Generally speaking, after adjusting the pitching angle, first lock the first locking screw 12, and then lock the second locking screw 13 to complete double locking to make the structure stable. The buckle 12 is arranged on the U-shaped mounting plate 14 and is used to fix the fire hose on the U-shaped mounting plate 14. Specifically, the buckle 15 includes a hook 16 and a clamping piece 17. The hook 16 is arranged on one side of the U-shaped mounting plate 14. The clamping piece 17 is an arc-shaped that fits the shape of the fire hose. One end of it is hinged to the other side of the U-shaped mounting plate 14, and the other end is lapped on the hook 16 and has a locking piece for locking the hook 16 and the clamping piece 17, which is used to cooperate with the U-shaped supporting structure of the U-shaped mounting plate 14 to firmly fix the fire hose. The buckle 15 is not limited to the structure as Figure 4 shown in the figure, and any structure that can realize the function of fixing the fire hose is acceptable.

[0046] As Figure 1 , 2 shown in the figure, the three-legged support assembly includes a movable three-legged seat 5, a three-legged support locking nut 6 and a three-legged support rod 7. The movable three-legged seat 5 is slidably sleeved on the fixed vertical rod 4. One end of the three-legged support rod 7 is hinged to the movable three-legged seat 5, and the other end is used to support on the ground and is threadedly connected to the movable three-legged seat 5 through the three-legged support locking nut 6 to lock the position of the movable three-legged seat 5 on the fixed vertical rod 4. Further, the three-legged support locking nut 6 is limited to the middle of the fixed vertical rod 4 by a retaining ring, and the movable three-legged seat 5 is located above the three-legged support locking nut 6. Specifically, there is a groove in the middle of the fixed vertical rod 4, and the retaining ring is arranged in the groove and protrudes from the groove. The three-legged support locking nut 6 is sleeved on the retaining ring, so that the retaining ring at least restricts the upward movement of the three-legged support locking nut 6. As Figure 9As shown, a convex part is provided at the bottom of the three - leg support locking nut 6, so that the retaining ring restricts the upward movement of the three - leg support locking nut 6. Grooves can also be correspondingly provided on the inner wall of the three - leg support locking nut 6. The retaining ring is placed between the groove of the three - leg support locking nut 6 and the groove of the fixed vertical rod 4, so that the retaining ring restricts the up - and - down movement of the three - leg support locking nut 6 and only allows it to rotate. The movable three - leg seat 5 has an external thread, and the three - leg support locking nut 6 has an internal thread. The external thread of the movable three - leg seat 5 can be thread - fitted and connected with the internal thread of the three - leg support locking nut 6. When the three - leg support assembly needs to be deployed, the movable three - leg seat 5 moves downward to above the three - leg support locking nut 6 and is thread - connected with it. The movable three - leg seat 5 can be appropriately held, and the three - leg support locking nut 6 is rotated to make the movable three - leg seat 5 move downward along the fixed vertical rod 4. When the three - leg support assembly needs to be retracted, the three - leg support locking nut 6 is rotated in the reverse direction to make the movable three - leg seat 5 move upward along the fixed vertical rod 4 and disengage from the three - leg support locking nut 6.

[0047] The three - leg support assembly further includes a support member 8 and a fixed three - leg seat 10. The fixed three - leg seat 10 is fixedly sleeved on the lower part of the fixed vertical rod 4. One end of the support member 8 is hinged to the fixed three - leg seat 10, and the other end is hinged to the middle of the three - leg support rod 7. The fixed three - leg seat 10 also enables the movable three - leg seat 5 to only move up and down along the fixed vertical rod 4 and not rotate. When the position of the movable three - leg seat 5 is locked by the three - leg support locking nut 6, the fixed vertical rod 4, the three - leg support rod 7 and the support member 8 form a stable triangular structure, and the three - leg support rod 7 can stably support on the ground. Specifically, three support rods can be arranged around the movable three - leg seat 5 for the three - leg support rod 7. Three support bars can be arranged around the fixed three - leg seat 10 for the support member 8, and they are respectively connected to the three support rods of the three - leg support rod 7. An adjustable foot 9 is provided at the lower end of the three - leg support rod 7, and anti - slip patterns can be provided on the bottom surface of the adjustable foot 9. The support member 8 is in a U - shaped structure, and both ends of the U - shaped structure are hinged to both sides of the three - leg support rod 7. As Figure 3 shown, when the fire hose bracket is not in use, the three - leg support rod 7 can be retracted, and the three - leg support rod 7 just fits into the interior of the U - shaped structure, thus reducing the storage space.

[0048] As Figures 5 to 8As shown, the buckle assembly 20 is arranged at the bottom of the fixed vertical rod 4 and is used for locking with the T-shaped column 114 embedded in the ground. The buckle assembly 20 includes a buckle main body 111, a buckle outer ring 112 and a spring pin 113. The buckle main body 111 is connected to the bottom of the fixed vertical rod 4 and has a cavity 115 inside for accommodating the upper part of the T-shaped column 114. An opening 116 is formed on its side for the upper part of the T-shaped column 114 to enter the cavity 115. The buckle outer ring 112 is movably sleeved on the buckle main body 111, and a movable opening 117 which is matched with the opening 116 and can be displaced up and down is formed on its side. The spring pin 113 is arranged between the buckle main body 111 and the buckle outer ring 112 and is clamped in the upper positioning hole 118 or the lower positioning hole 119 on the inner side of the buckle outer ring 112 to realize the up-and-down displacement of the opening 116 and the movable opening 117. The T-shaped column 114 is a T-shaped structure embedded in a groove set on the ground. The cross-sectional dimension of its upper part is larger than that of its lower part. The height and diameter of its upper part are slightly smaller than the height and diameter of the cavity, and the top surface of the T-shaped column 114 is not higher than the ground. Specifically, as Figure 8 As shown, the buckle main body 111 includes a connecting part 120 connected to the bottom of the fixed vertical rod 4, an extending part 121 extending outward from the lower end of the connecting part 120, a containing part 122 extending downward from the extending part 121, and a limiting part 123 extending inward from the lower end of the containing part 122 to a diameter equivalent to that of the lower part of the T-shaped column 114. The extending part 121, the containing part 122 and the limiting part 123 form a cavity 115 for accommodating the upper part of the T-shaped column 114. The opening 116 is formed on the side of the containing part 122 and the limiting part 123. The buckle outer ring 112 includes a clamping part 124 sleeved on the containing part 122, and the movable opening 116 is formed on the side of the clamping part 124. The spring pin 113 is arranged in the containing part 122, and the upper positioning hole 118 and the lower positioning hole 119 are arranged on the inner side of the clamping part 124. Two pairs of upper positioning holes 118 and lower positioning holes 119 can be symmetrically arranged on both inner sides of the clamping part 124, and spring pins 113 are arranged at corresponding positions of the containing part 122 to make the clamping more stable. When the buckle outer ring 112 is in the upper side position and the spring pin 113 is clamped in the lower positioning hole 119, the movable opening 117 and the opening 116 coincide, and the upper part of the T-shaped column 114 can enter the cavity 115, and the buckle assembly 20 is in the unlocked state. When the buckle outer ring 112 is in the lower side position and the spring pin 113 is clamped in the upper positioning hole 118, the movable opening 117 is lower than the opening 116, and the upper part of the T-shaped column 114 is limited in the cavity 115, and the buckle assembly 20 is in the locked state.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention and are not used to limit the implementation scope of the present invention. Any equivalent changes and modifications made within the protection scope of the present invention should be considered to fall within the protection scope of the present invention.
