[0027] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0028] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0029] like Figure 1-Figure 3As shown, a multifunctional interchangeable hose reel of the present invention includes a hose reel body 1, which is rotatably mounted on a hose reel bracket 8. The hose reel bracket 8 has two surfaces, which are respectively provided on both sides of the hose reel body 1. The two sides of the hose reel body 1 are rotatably mounted on the hose reel bracket 8. The structure of the hose reel body 1 is similar to that of the hose reel in the prior art and will not be described in detail here.

[0030] The invention also includes a screw transmission pair 2, which is installed on the pipe reel support 8. The main purpose of the screw transmission pair 2 is to allow the pipeline 4 to be rewound from one side to the other side of the pipe reel body when winding, so that the pipeline 4 can be evenly wound on the pipe reel body 1;

[0031] It also includes a gear drive module, which is installed between the pipe reel bracket 8 and the pipe reel main body 1. The gear drive module includes a switching gear 10. The transmission ratio between the pipe reel main body 1 and the gear drive module is adjusted by adjusting the meshing position of the switching gear 10 to meet the winding of pipelines 4 with different diameters; when different pipelines 4 need to be wound, different transmission ratios can be obtained by changing the transmission position of the switching gear 10, so that the pipeline 4 to be wound can always be wound evenly on the pipe reel main body 1. Therefore, when the diameter of the pipeline 4 changes, the pipe reeling rate of the screw gear fixed on the screw transmission pair 2 needs to be adjusted to meet the uniform winding of the pipeline 4.

[0032] In this embodiment, the screw transmission pair 2 and the pipe winding main body 1 are both meshed and driven by the gear drive module, and the gear drive module drives the guide wheel frame 3 to reciprocate along the screw transmission pair 2 and reciprocate the pipeline 4 from one side to the other.

[0033] Please continue reading Figure 2 and Figure 3 As shown, the gear drive module further includes a first transmission tooth 11 and a second transmission tooth 12, the first transmission tooth 11 and the second transmission tooth 12 are respectively engaged with the gear ring 13 on the winding tube body, the switching gear 10 is engaged with the first transmission tooth 11 or the second transmission tooth 12, and the transmission ratio between the screw gear 9, the switching gear 10 and the transmission teeth is adjusted by adjusting the switching gear 10 to different transmission tooth positions;

[0034] Wherein, the first transmission tooth 11 and the second transmission tooth 12 are both secondary gears;

[0035] The first transmission tooth 11 includes a first gear surface 112 and a second gear surface 111 , and the second transmission tooth 12 includes a third gear surface 121 and a fourth gear surface 122 . The first gear surface 112 and the third gear surface 121 have the same number of teeth and are both meshed with the ring gear 13 .

[0036] The second gear surface 111 and the fourth gear surface 122 have different numbers of teeth. The switching gear 10 is engaged with the second gear surface 111 or the fourth gear surface 122 to change the transmission ratio. In this way, when facing pipelines 4 of different diameters, by changing the transmission ratio, when the left and right reciprocating movement rate of the screw transmission pair 2 changes, the uneven winding problem caused by the different diameters of the pipeline 4 is compensated. Therefore, the present invention can be applied to the winding of pipelines 4 of different diameters, and is more universal. When the switching gear 10 rotates, the switching gear 10 will drive the screw transmission pair 2 to rotate, and will also contact and engage with the small gear ring on the first transmission tooth 11 or the second transmission tooth 12.

[0037] like Figure 4 and Figure 5 As shown, a driving link 73 is installed at one end of the switching gear 10, and the driving link 73 passes through the arc-shaped adjustment slot 5 on the reel bracket 8 and extends to the outside. The protruding end of the driving link 73 is installed with a driving part 7, and a positioning support 72 is installed between the driving part 7 and the reel bracket 8. The driving link 73 passes through the positioning support 72 and is connected to the driving part 7. A spring 71 is installed in the positioning support 72, and one end of the spring 71 is fixedly connected to the reel bracket 8, and the other end is fixedly connected to the positioning support 72. The driving part 7 is pressed toward one end surface of the reel bracket 8 by the spring 71. When the driving link 73 and the switching gear 10 are positioned, the spring 71 is used to reset the driving part 7.

[0038] like Figure 5 As shown, in order to prevent the driving part 7 from arbitrarily displacing along the arc-shaped adjustment groove 5 and being able to be located in one of the extreme positions, in this embodiment, the two extreme positions of the arc-shaped adjustment groove 5 are provided with a limit buckle groove 6, and a limit convex portion 74 is provided on the positioning support member 72. The limit convex portion 74 is buckled into the limit buckle groove 6 to limit the two extreme positions of the driving connecting rod 73 in the arc-shaped adjustment groove 5. The limit convex portion 74 is buckled into the limit buckle groove 6 by using the stretched spring 71, so that the driving connecting rod 73 cannot move along the arc-shaped adjustment groove 5. The adjusting groove 5 slides, and only when the driving part 7 is pulled outward, the limiting protrusion 74 will be separated from the limiting buckle groove 6. At this time, it can move along the arc-shaped adjusting groove 5. After moving, the switching gear 10 will be displaced to the other side. Assuming that it is initially at the position of the first transmission tooth 11, after moving to the next extreme position, the switching gear 10 will move to the second transmission tooth 12 and engage with the second transmission tooth 12. At this time, the switching gear 10 can be switched to a different meshing position to obtain a different gear transmission ratio, so as to realize the winding of other pipelines 4.

[0039] Among them, the screw transmission pair 2 includes a double-pitch screw, which is an existing technology. The general principle is as follows: two different pitch areas are set on the screw, and the thread directions of these two areas are opposite. When the screw nut 41 moves along one pitch area, it will automatically switch to another pitch area after reaching a specific position.

[0040] In this way, even if the motor always keeps rotating in one direction, when the lead screw nut 41 reaches a stroke end, it will enter the reverse pitch area, thereby continuing to move in the opposite direction to achieve reciprocating movement.

[0041] In this embodiment, both ends of the double-pitch screw are installed on the pipe winding bracket 8, and a screw gear 9 is installed on the double-pitch screw. The screw gear 9 is always engaged with the switching gear 10, and the switching gear 10 drives the screw gear 9 to rotate, thereby driving the double-pitch screw to rotate.

[0042] Here's how it works:

[0043] When the pipeline is pulled or recovered, the ring gear 13 rotates, and the rotation of the ring gear 13 drives the first transmission teeth and the second transmission teeth to rotate, and finally the rotation of the first transmission teeth and the second transmission teeth drives the switching gear 10 to rotate, and the switching gear 10 drives the lead screw gear 9 to rotate, thereby making the lead screw work. The present invention uses gears with different tooth ratios of the first transmission teeth and the second transmission teeth, and a switchable switching gear. During use, the switching gear is switched to contact different transmission teeth, thereby changing the sorting speed of the lead screw, so that pipelines of different sizes can be stored in the casing to the maximum extent.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
