[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.
[0021] See also Figures 1 to 3 The utility model provides a hose anti-bending sheath. The hose anti-bending sheath may include a plurality of sheath sections 1, each of which is a cylindrical structure. The sheath section 1 has a head end and a tail end, the head end 1 extends inward to form a head end limiting hook 11, the tail end extends outward to form a tail end limiting hook 12, and the middle part of the sheath section 1 extends outward to form a limiting rib 13. The plurality of sheath sections 1 are connected head to tail in sequence, and the head end limiting hook 11 is movably hooked with the tail end limiting hook 12 and the limiting rib 13 of the previous sheath section 1.
[0022] The hose 9 passes through the middle of each sheath section 1, and there is a gap between the hose 9 and each sheath section 1 for each sheath section 1 to move. The head end limit hook 11 can move and bend between the tail end limit hook 12 and the limit rib 13, so that the hose 9 can be bent to a desired angle. However, the positional relationship between the head end limit hook 11, the tail end limit hook 12 and the limit rib 13 also limits the bending angle between two adjacent sheath sections 1, limits the minimum radius of the hose 9 that can be bent, and avoids damage to the hose 9 caused by excessive bending.
[0023] In some embodiments, the head end limit hook 11 is in the shape of a circular ring and is perpendicular to the axis of the sheath section 1, that is, the head end of the sheath section 1 extends radially inward in a circle to form the head end limit hook 11. The tail end limit hook 12 is in the shape of a circular ring and is perpendicular to the axis of the sheath section 1, that is, the tail end of the sheath section 1 extends radially outward in a circle to form the head end limit hook 12. The limit rib 13 is in the shape of a circular ring and is perpendicular to the axis of the sheath section 1, that is, the middle part of the sheath section 1 extends radially outward in a circle to form the limit rib 13. And preferably, the inner diameter of the head end limit hook 11 is smaller than the outer diameter of the tail end limit hook 12, so that when the sheath sections 1 are connected head to tail, the head end limit hook 11 and the tail end limit hook 12 of the two adjacent sheath sections will not loosen.
[0024] In some embodiments, the portion of the sheath section 1 close to the head end protrudes outward to form a protrusion 14, and the inner side of the protrusion 14 forms a receiving groove for receiving the tail limiting hook 12 of the previous sheath section.
[0025] In some embodiments, in order to facilitate installation of the sheath section 1 and to enable replacement of the sheath section 1 when the hose 9 is in a connected state, the sheath section 1 adopts a splicing structure. That is, the sheath section 1 is divided into two identical halves 10 with the plane where the axis of the sheath section 1 is located as the dividing interface, and the two halves 10 are relatively abutted to form the sheath section 1. It is easy to understand that the hose anti-bending sheath also includes a fixing member 2, which is detachably connected to the two halves 10 and is used to fix the two halves 10.
[0026] In some embodiments, the fixing member 2 is a pipe hoop, which is sleeved on the outer wall of the sheath section 1 and located between the limiting rib 13 and the protrusion 14. In other embodiments, the fixing member 2 can also be a rope, a binding belt, etc., as long as the fixing effect can be achieved.
[0027] The pipe clamp groove for placing the pipe clamp is preferably designed as an inverted trapezoidal structure with one side at a right angle and one side at a slope, and the bottom width is smaller than the width of the pipe clamp. When the pipe clamp is tightened, the pipe clamp is squeezed by the inclined surface and slides to the right angle side, pushing the two half bodies 10 to align. In this way, when the pipe clamp is completely tightened, the misalignment of the half bodies 10 is also eliminated by the pipe clamp, so that the sheath remains aligned during use and will not be misaligned or deformed due to movement and external force.
[0028] In some embodiments, in order to fix the sheath section 1 on the hose 9, the hose anti-bending sheath further includes a sheath connector 3. One end of the sheath connector 3 forms a first connection portion 31, and the other end of the sheath connector forms a second connection portion 32. The first connection portion 31 is used to connect the hose 9 or a water supply pipe connected to the hose 9 (the hose anti-bending sheath is generally installed at the connection between the hose 9 and the water supply pipe). The shape and structure of the first connection portion 31 are adapted to the connected part. The second connection portion 32 has the same structure as the tail end limit hook 12, and the second connection portion 32 is movably connected to the head end limit hook 11 of the first sheath section 1 in the same way.
[0029] Similarly, in a preferred embodiment, the sheath joint 3 can also be divided into two identical monomers 30 in the same manner as the sheath section 1. The two monomers 30 are relatively abutted to form the sheath joint 1, and the fixing member 2 is also detachably connected to the two monomers 30 to fix the sheath joint 3.
[0030] Compared with the prior art, the hose anti-bending sheath provided by the utility model has the sheath sections connected end to end in sequence to form a group of bendable sheaths. The sheath has a rigid minimum bending radius limit, which limits the minimum radius of the hose that can be bent, and avoids damage to the hose caused by excessive bending.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
