Electric hand-cranking hose reel

Abstract

The application discloses an electric hand-cranking hose reel, which comprises a base, a reel component, a motor, a manual input shaft and a hand-cranking lever. When the motor is used to drive the reel component to rotate, the hand-cranking lever is connected to the base, occupies a small space and does not affect the use of the reel. When the manual input shaft is used to drive the reel component to rotate, the hand-cranking lever is connected to the manual input shaft, the manual input shaft and the rotating shaft of the reel component are perpendicular, and the hand-cranking lever can be rotated while the winding condition of the hose on the reel component is observed. When the motor drives the reel component to rotate, the manual input shaft can rotate together, and when the manual input shaft drives the reel component to rotate, the first transmission pair can be released. The electric hand-cranking hose reel has the beneficial effects that the reel component can be driven to rotate by the motor or manually, and the application scenarios are more extensive.

Description

Technical Field

[0001] This application relates to reels, and more particularly to an electric hand-cranked hose reel. Background Technology

[0002] A hose reel typically comprises: a base, a reel assembly rotatably connected to the base for winding the hose, and a drive mechanism for rotating the reel assembly. The drive mechanism is generally either electrically driven by a motor with a speed reduction gear, or manually driven by a hand crank. Motor-driven rotation is efficient and labor-saving, but requires an external power source, and the power cord restricts the reel's movement. Manual rotation is less efficient and requires more effort, but is not limited by power supply conditions or movement limitations.

[0003] Existing drive mechanisms for reels allow users to choose between electric motors and manual operation, but there is a lack of systems that combine both methods. Utility Model Content

[0004] This application aims to provide an electric hand-cranked hose reel that combines motor and manual operation, allowing users to choose the appropriate method depending on the situation.

[0005] This application provides an electric hand-cranked hose reel, comprising: Base; The reel component includes: a rotating shaft and a reel body; the rotating shaft is rotatably connected to the base about a horizontal axis; the reel body is fixedly connected to the rotating shaft; The motor is fixedly connected to the base; the output shaft is horizontal and a first transmission pair is provided between it and the reel component; The manual input shaft is rotatably connected to the base around a horizontal axis, and a second transmission pair is provided between it and the reel component; The hand crank is detachably connected to the base or the manual input shaft; when the connection is to the manual input shaft, it restricts the relative rotation between the hand crank and the manual input shaft.

[0006] In some embodiments, the manual input shaft is inserted and fixed with a radially extending pin; the hand crank includes: a sleeve and a rocker arm; the end face of the sleeve away from the rocker arm has two notches that mate with the pin; the base is fixed with an inverted plate, and the two horizontal pieces of the inverted plate each have insertion holes that mate with the sleeve.

[0007] In some embodiments, the lower insertion hole also has a limiting strip that mates with the two notches; with the two notches engaged with the limiting strip, the rocker arm remains in a horizontal longitudinal position.

[0008] In some embodiments, the base is rotatably connected to a double sprocket; the first transmission pair includes: a first chain pair for speed reduction between the motor's output shaft and the double sprocket, and a second chain pair for speed reduction between the double sprocket and the reel component.

[0009] In some embodiments, the rotating shaft is hollow, with a plug connected to one end and a rotary joint connected to the other end, and a connecting pipe connected to the outer wall of the disc.

[0010] In some embodiments, the base has a mounting block that can slide and be fixed horizontally; the manual input shaft is a mounting block at the connection position of the base, so that the second transmission pair can switch between two states of separation and engagement.

[0011] In summary, this application provides an electric hand-cranked hose reel, comprising: a base, a reel component, a motor, a manual input shaft, and a hand crank. When the motor drives the reel component to rotate, the hand crank is connected to the base, occupying minimal space and not affecting the use of the reel. When the manual input shaft drives the reel component to rotate, the hand crank is connected to the manual input shaft, and the manual input shaft and the rotation axis of the reel component are perpendicular, allowing for observation of the hose winding on the reel component while rotating the hand crank. When the motor drives the reel component to rotate, the manual input shaft can rotate simultaneously, and when the manual input shaft drives the reel component to rotate, the first transmission pair can be disengaged. The advantages are: the reel component can be driven by either a motor or manually, making it more widely applicable. Attached Figure Description

[0016] Please see Figure 1 , Figure 3 and Figure 4 An electric hand-cranked hose reel includes: a base 1, a reel component 2, a motor 3, a manual input shaft 4, and a hand crank 5.

[0017] The base 1 is used to place the entire reel on the ground. More specifically, the base 1 may include two plate-shaped side sheet metal parts 11 and two strip-shaped connecting sheet metal parts 12. The two side sheet metal parts 11 and the two connecting sheet metal parts 12 are fixed together by fasteners.

[0018] Please see Figure 1 and Figure 2 The reel component 2 includes: a rotating shaft 21 and a reel body 22.

[0019] The rotating shaft 21 is rotatably connected to the base 1. More specifically, the top surfaces of the two side sheet metal parts 11 can be equipped with first bearing seats 1A, and the two ends of the rotating shaft 21 are respectively connected to the two first bearing seats 1A. For the convenience of subsequent description of the orientation, the axis of the rotating shaft 21 is set to horizontal.

[0020] The reel body 22 is used for winding the hose, and the reel body 22 includes: a circular winding drum 221 and baffles 222 at both ends of the winding drum 221. The reel body 22 is fixedly connected to the rotating shaft 21, that is, the reel body 22 and the rotating shaft 21 are driven to rotate together, thereby realizing winding or unwinding.

[0021] Please see Figure 1 The motor 3 is fixedly connected to the base 1, and the output shaft of the motor 3 is horizontal. More specifically, the fixed connection position of the motor 3 can be the vertical outer wall of the side sheet metal part 11.

[0022] A first transmission pair 6 is provided between the motor 3 and the reel component 2, that is, the motor 3 drives the reel component 2 to rotate through the first transmission pair 6.

[0023] Please see Figure 2 In some embodiments, the base 1 is rotatably connected to a double sprocket 1B. More specifically, similar to the motor 3, the connection position of the double sprocket 1B is also the vertical outer wall of the side sheet metal part 11. The first transmission pair 6 includes: a first chain pair 61 between the output shaft of the motor 3 and the double sprocket 1B, and a second chain pair 62 between the double sprocket 1B and the reel component 2. Both the first chain pair 61 and the second chain pair 62 are reduction drives, that is, the first transmission pair 6 is a two-stage reduction.

[0024] The double sprocket 1B may include: a first large sprocket 1B1 and a second small sprocket 1B2; the output shaft of the motor 3 may be fixedly connected to the first small sprocket 3A; a chain pair 61 is connected between the first small sprocket 3A and the first large sprocket 1B1; a second large sprocket 22A is fixedly connected to the vertical outer wall of one side of the disc body 22; and a chain pair 62 is connected between the second small sprocket 1B2 and the second large sprocket 22A.

[0025] Please see Figure 1 and Figure 3 The manual input shaft 4 is rotatably connected to the base 1 about a horizontal axis. More specifically, a second bearing seat 1C can be mounted on the top surface of one of the side sheet metal parts 11, and the manual input shaft 4 is connected to the second bearing seat 1C.

[0026] A second transmission pair 7 is provided between the manual input shaft 4 and the reel component 2, that is, in addition to using the motor 3, the manual input shaft 4 can also be manually rotated to drive the reel body 22 and the rotating shaft 21 to rotate together, thereby realizing winding or unwinding.

[0027] Additionally, when manually rotating the manual input shaft 4 to drive the disc body 22 and the rotating shaft 21 to rotate together, the first transmission pair 6 can be disengaged, making manual rotation easier. In the embodiment where "the base 1 is rotatably connected to a double sprocket 1B", a detachable connecting pin can be used to connect the two chain links in the chain pair 62. Disassembling the connecting pin disconnects the chain, thus disengaging the first transmission pair 6.

[0028] Please see Figure 3 In some embodiments, the base 1 has a mounting block 1D that can be slidably fixed in a horizontal direction.

[0029] More specifically, the mounting block 1D has a round hole, and the top surface of the side sheet metal part 11 has a waist-shaped groove. Fasteners are used to fix the connection between the mounting block 1D and the side sheet metal part 11. Loosening the fasteners allows the mounting block 1D to move relative to the base 1.

[0030] The manual input shaft 4 is connected to the mounting block 1D on the base 1, that is, the aforementioned second bearing seat 1C is fixedly connected to the mounting block 1D. By adjusting the fixed position of the mounting block 1D on the base 1 in the horizontal direction, the second transmission pair 7 can be switched between the disengaged and engaged states.

[0031] Please see Figure 3 Correspondingly, the second transmission pair 7 can be a bevel gear pair, or it can be a disc 22 with a uniform circular array of notches 22B around the rotating shaft 21, with a third sprocket 4A fixedly connected to the manual input shaft 4, the teeth of the third sprocket 4A meshing with the notches 22B. Combining the above "the base 1 is rotatably connected to the double sprocket 1B", this notch 22B can be set on the second large sprocket 22A.

[0032] When the reel assembly 2 is driven to rotate by the motor 3, the second transmission pair 7 can be disengaged. When the reel assembly 2 is driven to rotate by the manual input shaft 4, the second transmission pair 7 can be re-engaged.

[0033] The hand crank 5 is detachably connected to the base 1 or the manual input shaft 4. When the hand crank 5 is connected to the manual input shaft 4, the relative rotation between the hand crank 5 and the manual input shaft 4 is restricted. That is, when the reel component 2 is driven to rotate by the motor 3, the hand crank 5 is connected to the base 1; when the reel component 2 is driven to rotate by the manual input shaft 4, the hand crank 5 is connected to the manual input shaft 4.

[0034] Please see Figure 3 and Figure 4In some embodiments, the manual input shaft 4 is inserted and fixed with a radially arranged pin 4B.

[0035] The hand crank 5 includes a sleeve 51 and a rocker arm 52. The end face of the sleeve 51 away from the rocker arm 52 has two first notches 51A that engage with the pin 4B. That is, when the hand crank 5 is connected to the manual input shaft 4, the sleeve 51 is fitted onto the manual input shaft 4, and the two ends of the pin 4B respectively enter the two first notches 51A.

[0036] The base 1 is fixedly provided with an inverted plate 1E, and both horizontal pieces of the inverted plate 1E have insertion holes 1E1 for the sleeve 51. That is, when the hand crank 5 is connected to the base 1, the sleeve 51 is inserted into these two insertion holes 1E1.

[0037] Please see Figure 4 and Figure 5 Furthermore, the lower insertion hole 1E1 also has a limiting strip 1E2 that mates with the two first notches 51A. When the two first notches 51A are engaged with the limiting strip 1E2, the rocker arm 52 remains in a horizontal longitudinal position.

[0038] Please see Figure 6 and Figure 7 In some embodiments, the rotating shaft 21 is hollow, with a plug 21A connected to one end and a rotary joint 21B connected to the other end. A connecting pipe 21C is connected to the outer wall of the disc body 22. One end of the flexible hose is connected to the connecting pipe 21C.

[0039] One end face of the winding drum 221 has a second notch 221A that mates with the connecting pipe 21C. Multiple connecting rods 221B can be welded to the inner wall of the winding drum 221, and a baffle 222 is fixedly connected to the connecting rods 221B by screws. Two flanges 21D are fixedly connected to the rotating shaft 21, and the baffle 222 is also fixedly connected to the flanges 21D by screws.

[0040] The rotary joint 21B can be connected to an air compressor, water pump, etc., to send air, water, etc. through the rotating shaft 21 and connecting pipe 21C into the hose.
