DETAILED DESCRIPTION

[0070] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thoroughly and completely understood, and will fully convey the scope of the application to those skilled in the art.

[0071] As shown in FIGS. 1-9, the embodiment of the present application provides a winding mechanism, comprising: a support part 1, a hose 2; further comprising: a rotating part arranged in the support part 1 and rotating around the inner axis of the support part 1; a winding part arranged on the rotating part and moving with the rotating part to uniformly place the hose 2; a fixed driving part connected with the rotating part to drive the rotating part to slide along the inner part of the support part 1; a fixed drawing part arranged on the support seat to fix the position of the hose 2 during winding or drawing; and a locking part arranged on the support part 1 to facilitate fixing the hose 2 at a specified position.

[0072] In the embodiment of the present application, the winding part is arranged to enable the hose 2 to be wound on the winding part in a regular manner, thereby avoiding the hose 2 from being wound together during winding; the fixed drawing part is arranged to fix the position of the hose 2 during drawing, thereby preventing the hose 2 from being wound due to different positions during winding; the cooperation between the rotating part and the fixed driving part enables the rotating part to rotate when the hose 2 is pulled to drive the winding part to rotate, thereby changing the position of the winding part under the action of the fixed driving part, so that the winding part moves with the hose 2 during winding or drawing, thereby ensuring that the hose 2 will not be bent at a large angle when the hose 2 is drawn out of the fixed drawing part, thereby ensuring the smoothness of water flow.

[0073] As shown in FIG. 1 to FIG. 9, the support part 1 comprises: a support cylinder 101, the inner wall of which is in sliding connection with the rotating part; a first clamping groove 106, which is provided on the inner wall of the support cylinder 101 and is in clamping connection with the rotating part to limit the movement of the rotating part; a first fixed plate 102, which is provided on both sides of the support cylinder 101 and is fixed by a first fixing member 103 to fix the position of the support part 1; and a second fixed plate 104, which is provided on the top end of the support cylinder 101 and is connected with the fixed part 5.

[0074] In the embodiment of the present application, the support cylinder 101 is fixedly connected with the outside through the first fixed plate 102 to ensure that the position of the support cylinder 101 is unchanged. The support cylinder 101 is fixed through the first fixed plate 102 by the first fixing member 103, such as a bolt, a pin and the like. Meanwhile, the second fixed plate 104 is provided on the support cylinder 101, thereby facilitating the fixation of the fixed winding and unwinding part.

[0075] As shown in FIG. 1 to FIG. 9, the rotating part comprises: a sliding cylinder 6, which is provided in the support cylinder 101; a first clamping block 603, which is provided on the outer wall of the sliding cylinder 6 and is matched with the first clamping groove 106 to limit the rotation of the sliding cylinder 6; a coil spring 605, which is provided in the sliding cylinder 6 and has one end connected with the sliding cylinder 6; and a rotating member, which is provided in the sliding cylinder 6 and has the other end connected with the coil spring 605.

[0076] In the embodiment of the present application, the first clamping block 603 moves along the first clamping groove 106, thereby driving the sliding cylinder 6 to move in the support cylinder 101. Meanwhile, the sliding cylinder 6 is prevented from rotating in the support cylinder 101 by the first clamping block 603 and the first clamping groove 106. Meanwhile, the coil spring 605 is provided. When the rotating member rotates to a certain extent, the coil spring 605 is pulled to contract and generate elasticity. When the rotating force of the rotating member disappears, the coil spring 605 rebounds, thereby driving the rotating member to rotate reversely. Since the rotating member is connected with the winding part, the winding part is driven to rotate. Therefore, when the hose 2 needs to be wound and unwound, it is only needed to loosen the control of the hose 2, so that the hose 2 can be wound and unwound automatically under the action of the coil spring 605, which is more convenient.

[0077] As shown in FIG. 1 to FIG. 9, the rotating member comprises: a rotating cylinder 604, which is provided in the sliding cylinder 6 and has the outer surface connected with the other end of the coil spring 605; a first threaded groove 602, which is provided on the rotating cylinder 604 and is matched with the winding part to drive the winding part to rotate synchronously; and a six-rib threaded sleeve 601, which is provided on the rotating cylinder 604 and is in rotating connection with the rotating cylinder 604 and is matched with the winding part to facilitate disassembly.

[0078] In the embodiment of the present application, the first thread groove 602 and the hexagonal thread sleeve 601 are arranged to facilitate the installation of the winding part on the rotating cylinder 604, so that the winding part rotates synchronously with the rotating cylinder 604; wherein the hexagonal thread sleeve 601 is rotationally connected with the rotating cylinder 604, that is, the position of the winding part can be limited, and the installation and disassembly are facilitated.

[0079] As shown in FIGS. 1-9, the winding part includes a winding member connected with the rotating cylinder 604 to wind and unwind the hose 2; and a connecting member penetrating in the winding member and connected with an external water valve at one end to make the hose 2 in water use.

[0080] In the embodiment of the present application, the winding member is arranged to regulate the winding and unwinding of the hose 2, so as to avoid the situation that multiple hoses 2 are wound together when the winding member is rotated; and the connecting member is arranged to make the one end of the hose 2 connected with the external water valve rotate with the winding member, so as to reduce the torsional stress of the hose 2 when the hose 2 is wound and unwound, thereby improving the durability of the hose 2.

[0081] As shown in FIGS. 1-9, the winding member includes a first threaded tube 404 engaged with the first thread groove 602; a winding tube 4 connected with the first threaded tube 404 at one end and sleeved on the connecting member; a second clamping groove 402 opened on the inner wall of the winding tube 4; a hexagonal hole 405 opened on the one end of the winding tube 4 close to the first threaded tube 404 and cooperated with the hexagonal thread sleeve 601; a winding groove 401 opened on the winding tube 4, and the winding groove 401 is in a threaded shape to facilitate uniform placement of the hose 2; and a wire blocking plate 403 arranged at the one end of the winding tube 4 away from the first threaded tube 404 to limit the hose 2.

[0082] In the embodiment of the application, the winding pipe 4 is installed on the rotating cylinder 604. First, the hexagonal hole 405 is aligned with the hexagonal threaded sleeve 601 and inserted into the first threaded pipe 404 and the first threaded groove 602, at this time, the first threaded pipe 404 is rotated by rotating the winding pipe 4, so that the first threaded pipe 404 is engaged into the first threaded groove 602, thereby completing the installation and fixation of the winding pipe 4; wherein, during installation, the hexagonal threaded sleeve 601 rotates together along the rotating cylinder 604 under the limitation of the hexagonal hole 405, and after the winding pipe 4 is installed and fixed on the rotating cylinder 604, the winding pipe 4, the rotating cylinder 604 and the hexagonal threaded sleeve 601 move synchronously. The winding groove 401 is provided in a threaded manner, facilitating the clamping of the hose 2 in the winding groove 401, so that the hose 2 is wound around the winding pipe 4 in a spiral shape when winding, thereby reducing the risk of the hose 2 being wound together; when the hose 2 is pulled out, the hose 2 is easily released from the limitation of the winding groove 401, and the blocking plate 403 provided at one end of the winding pipe 4 further limits the hose 2, thereby ensuring that the hose 2 still in the winding groove 401 will not be released from the winding groove 401 under the action of the pulling force when the hose 2 is pulled out, thereby ensuring the standardization of the winding and unwinding of the hose 2 during the unwinding process.

[0083] As shown in FIGS. 1-9, the connecting piece includes: a rotating cylinder 3, which is arranged on the winding pipe 4 and is rotatably connected to the external water valve at one end; a second clamping block 302, which is arranged on the rotating cylinder 3 and cooperates with the second clamping groove 402; an L-shaped connecting pipe 201, one end of which is connected to one end of the hose 2; and a second connecting pipe 301, which is arranged on the rotating sleeve close to the external water valve at one end and is connected to the other end of the L-shaped connecting pipe 201.

[0084] In the embodiment of the application, the L-shaped connecting pipe 201 is arranged, one end of which is connected to the second connecting pipe 301 and the other end of which is connected to one end of the hose 2, so that the hose 2 can be connected to the external water valve at a smaller twisting angle through the L-shaped design; meanwhile, the second clamping block 302 cooperates with the second clamping groove 402, so that the rotating cylinder 3 can rotate with the winding pipe 4 when the winding pipe 4 rotates, and the second clamping block 302 slides in the second clamping groove 402 when the winding pipe 4 moves horizontally, so that the rotating cylinder 3 does not move with the winding pipe 4, thereby enabling the second connecting pipe 301 to only rotate and not to move; through the characteristics of the second connecting pipe 301 only rotating and not moving, one end of the hose 2 connected through the L-shaped connecting pipe 201 can only move around the winding pipe 4 without changing its horizontal position.

[0085] The rotating cylinder 3 is rotatably connected with the external water valve, and is in a sealed state during rotation. An annular groove is arranged on the water valve and connected with the second connecting pipe 301, so that water is continuously supplied to the second connecting pipe 301 when the rotating cylinder 3 rotates.

[0086] As shown in FIGS. 1-9, the fixed driving part comprises a first threaded rod 303, which is arranged in the rotating cylinder 3, one end of which is threadedly connected with the six-ribbed threaded sleeve 601, and the other end of which is fixedly connected with the external water valve.

[0087] In the embodiment, one end of the first threaded rod 303 is threadedly connected with the six-ribbed threaded sleeve 601, and the other end is fixedly connected with the external water valve. When the hose 2 is pulled, the winding pipe 4 is rotated, so that the rotating cylinder 604 and the six-ribbed threaded sleeve 601 are synchronously rotated. At this time, the six-ribbed threaded sleeve 601 is rotated, and the first threaded rod 303 is moved forward and backward along the six-ribbed threaded sleeve 601. Since the first threaded rod 303 is fixed on the external water valve and remains unchanged, the six-ribbed threaded sleeve 601 is moved in the opposite direction along the first threaded rod 303, so that the sliding cylinder 6 is moved along the sliding groove 105 through the rotating cylinder 604, and the winding pipe 4 is moved, so that the hose 2 is always kept in engagement with the winding groove 401 when the hose 2 is pulled out.

[0088] As shown in FIGS. 1-9, the fixed driving part comprises a first threaded rod 303, which is arranged in the rotating cylinder 3, one end of which is threadedly connected with the six-ribbed threaded sleeve 601, and the other end of which is fixedly connected with the external water valve.

[0089] In the embodiment, the hose 2 is pulled out by manually holding the handle 202. The third fixed plate 501 and the limiting pipe 502 are arranged, so that the position of the hose 2 is unchanged when the hose 2 is pulled out and retracted, and the stability of the device is improved.

[0090] As shown in FIG. 1 to FIG. 9, the locking part comprises: a heart-shaped clamping groove 606, which is arranged on the upper surface of the sliding cylinder 6; two groups of limiting through grooves 702, which are arranged on the support cylinder 101; a clamping curved needle 701, one end of which is in sliding connection with the upper end of the support cylinder 101, and the other end of which is arranged in the limiting through groove 702 and is in connection with the heart-shaped clamping groove 606 on the sliding cylinder 6; a support block 704, which is arranged on the support cylinder 101; and a limiting spring 703, one end of which is connected with the top end of the support cylinder 101, and the other end of which is connected with the bottom end of the support block 704, and the bottom end of the limiting spring 703 is in abutting connection with the clamping curved needle 701.

[0091] In the embodiment of the present application, when the sliding cylinder 6 slides outward along the sliding barrel groove 105, one end of the clamping curved needle 701 moves to the top end of the heart-shaped clamping groove 606 along the heart-shaped clamping groove 606, at this time, the clamping curved needle 701 is clamped at the top end of the heart-shaped clamping groove 606, so that the sliding cylinder 6 cannot move in the opposite direction, thereby the hose 2 is automatically locked and cannot be automatically retracted even if the external force is removed; when the hose 2 is pulled outward, the sliding cylinder 6 slides outward along the sliding barrel groove 105, thereby the sliding cylinder 6 extrudes the clamping curved needle 701, the clamping curved needle 701 is removed from the top end of the heart-shaped clamping groove 606, and the sliding cylinder 6 can move in the opposite direction, that is, the hose 2 can be automatically retracted.

[0092] Among them, the two groups of limiting through grooves 702 can adjust the clamping curved needle 701 of different lengths, because the clamping curved needle 701 is in different positions, the positions of the heart-shaped clamping groove 606 clamped are also different, thereby the length of the hose 2 after being extracted and locked can be locked in two different lengths, thereby the working environment can be more adapted.

[0093] Working principle: when the hose 2 is put out, the person holds the handle 202 and pulls the hose 2 upwards, the hose 2 moves upwards along the limiting pipe 502, at the same time, the winding pipe 4 rotates, the winding pipe 4 drives the rotating cylinder 604 and the six-ribbed threaded sleeve 601 to rotate, the winding spring 605 is arranged, when the rotating cylinder 604 rotates, the winding spring 605 is pulled to contract and generate elasticity; one end of the first threaded rod 303 is in threaded connection with the six-ribbed threaded sleeve 601, and the other end is fixedly connected with the external water valve, since the first threaded rod 303 is fixed on the external water valve and keeps still, the six-ribbed threaded sleeve 601 moves away from the second connecting pipe 301 along the first threaded rod 303, the sliding cylinder 6 is driven by the rotating cylinder 604 to move along the sliding through groove 105, so that the winding pipe 4 moves, when the hose 2 is pulled out, the winding pipe 4 moves together with the hose 2, so that when the hose 2 is pulled out, the position where the hose 2 and the winding pipe 4 are just separated keeps in the same straight line with the limiting pipe 502, so that the hose 2 is prevented from being misaligned on the winding pipe 4.

[0094] When the hose 2 is wound, the handle 202 is manually loosened, the winding spring 605 rebounds, so as to drive the rotating cylinder 604 to rotate reversely, thereby driving the winding pipe 4 and the six-ribbed threaded sleeve 601 to rotate reversely, so that the six-ribbed threaded sleeve 601 moves towards the second connecting pipe 301 along the first threaded rod 303, at this time, the movement state of the winding pipe 4 is that the winding pipe 4 rotates and moves forward at the same time, so that when the hose 2 is wound, the hose 2 is attached to the winding groove 401 and moves forward slowly, so that the next section of the hose 2 is attached to the next section of the winding groove 401, so that the hose 2 is prevented from being wound together when the hose 2 is wound; finally, the winding is completed, the handle 202 is attached to the limiting pipe 502, so that the winding of the hose 2 is completed.

[0095] The above is the preferred embodiment of the application, it should be pointed out that, for those skilled in the art, without departing from the principle of the application, a number of improvements and refinements can be made, these improvements and refinements should also be regarded as the protection scope of the application.
