Description

Technical Field

[0001] The invention belongs to the technical field of sunshade hanging umbrellas and relates to a hand-cranking device for a sunshade hanging umbrella. Background Art

[0002] As an outdoor leisure appliance, a sunshade hanging umbrella is widely used in leisure places such as squares, beaches, parks and courtyards, providing people with a comfortable space for taking shelter from the sun.

[0003] For example, a hanging umbrella disclosed in a Chinese patent with the publication number CN201585528U. The hanging umbrella includes a vertical rod, an inclined rod, a pull rod, an umbrella frame, a positioning device and a hand-cranking device. One end of the pull rod is connected to the top of the vertical rod, and the other end of the pull rod is installed on the umbrella frame. The positioning device is arranged on the vertical rod, and the hand-cranking device is arranged on the inclined rod. One end of the hand-cranking device is connected to the positioning device, and the other end of the hand-cranking device is connected to the umbrella frame through the inclined rod. The hand-cranking device is used to control the opening and closing of the umbrella frame. Since the inclined rod and the positioning device are connected together through the hand-cranking device, when the hand-cranking device fails and needs to be repaired, the hand-cranking device will be removed from between the inclined rod and the positioning device. After the hand-cranking device is removed, the inclined rod cannot be supported by the vertical rod, and the inclined rod is in a natural hanging state under the action of gravity. After the repair of the hand-cranking device is completed, the inclined rod needs to be supported upward before the hand-cranking device can be reinstalled between the positioning device and the inclined rod. Moreover, the hand-cranking shaft in the hand-cranking device is arranged in the inclined rod. When disassembling, the components on the hand-cranking shaft need to be removed, and the entire hand-cranking shaft needs to be pulled out from the inclined rod, which is inconvenient for disassembly. After an umbrella surface is installed on the inclined rod and the umbrella frame to form an umbrella body, the above-mentioned hanging umbrella can control the opening and closing of the umbrella frame through the hand-cranking device, making the hanging umbrella convenient to use, but there are still deficiencies: when the hand-cranking device fails and needs to be maintained, the workload of disassembly and reinstallation is large, resulting in inconvenient maintenance. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the invention provides a hand-cranking device for a sunshade hanging umbrella. The technical problem to be solved by the invention is: how to improve the convenience of maintenance.

[0005] The purpose of the invention can be achieved by the following technical solutions:

[0006] A cranking device for a sunshade hanging umbrella. The sunshade hanging umbrella includes a vertical column and an inclined rod for supporting the umbrella ribs. The inclined rod is hollow, and a cord is threaded through the inner cavity of the inclined rod. The cranking device includes a cranking housing and a wire wheel assembly for controlling the winding and unwinding of the cord. A relief notch communicating with the inner cavity of the cranking housing is provided on the side wall of the cranking housing. One end of the inclined rod is connected to the vertical column, and a wire passing hole communicating with the inner cavity of the inclined rod is provided on the outer peripheral surface of the inclined rod. The side part of the inclined rod is fitted in the relief notch, and the part of the inclined rod with the wire passing hole is located in the inner cavity of the cranking housing. The cranking housing and the inclined rod are detachably connected. The wire wheel assembly is rotatably installed in the cranking housing and is located outside the inclined rod. The cord can pass through the wire passing hole and be connected to the wire wheel assembly.

[0007] The vertical column of the sunshade hanging umbrella provides a supporting function for the entire umbrella frame. The hollow inclined rod is used to support and suspend the umbrella ribs and the umbrella surface. The inner cavity of the inclined rod allows the cord to pass through to control the opening and closing of the umbrella ribs. The wire wheel assembly of the cranking device can drive the rotation to wind and unwind the cord for locking, realizing the convenient control of the opening and closing of the umbrella surface. The cranking housing provides decoration and protection for the wire wheel assembly. When using the cranking device, the cranking housing is fixed on the inclined rod, and the wire wheel assembly is rotated to wind and unwind the cord. The cord winds and unwinds through the wire passing hole in and out of the inner cavity of the inclined rod, realizing the control of the cord by the wire wheel assembly. When maintenance of the cranking device is required, the cranking housing can be directly detached from the inclined rod. Since the wire wheel assembly is installed in the cranking housing and is located outside the inclined rod, that is, the wire wheel assembly is only connected to the cranking housing and not to the inclined rod, no additional disassembly operation is required for the wire wheel assembly when the cranking housing is detached. Moreover, the inclined rod is directly connected to the vertical column instead of being connected to the vertical column through the cranking device. The process of detaching the cranking device from the inclined rod for maintenance does not need to change the connection relationship between the inclined rod and the vertical column, avoiding the phenomenon of difficult reset due to torque influence after detaching the inclined rod, and greatly reducing the workload and difficulty of maintenance disassembly. Therefore, the cranking device of this sunshade hanging umbrella improves the convenience of maintenance while not affecting the control of the cord winding and unwinding by the cranking device.

[0008] In the above-mentioned cranking device of the sunshade hanging umbrella, the cranking housing includes a detachable first half shell and a second half shell. The wire wheel assembly is located between the first half shell and the second half shell. The first half shell and the second half shell are snapped together to form the relief notch, and the first half shell and the second half shell are respectively detachably connected to both sides of the inclined rod. After such a setting, when only the wire wheel assembly has problems, the user can separately detach the first half shell or the second half shell, and the complete wire wheel assembly can be exposed for maintenance, greatly improving the convenience of maintaining the cranking device.

[0009] In the above-mentioned sunshade umbrella handle device, the line wheel assembly includes a winding wheel for storing the rope, and a rotatable line pulley is connected to the inner cavity of the inclined rod, the axis of the line pulley is parallel to the axis of the winding wheel, and the line hole is located between the line pulley and the winding wheel. By arranging a rotatable line pulley in the inner cavity of the inclined rod, the rope can be placed in the wheel groove of the line pulley, so that the line pulley guides the rope to adapt to the length direction of the inclined rod in the inner cavity of the inclined rod, and the axis of the line pulley is parallel to the axis of the winding wheel, and the line hole is located between the line pulley and the winding wheel. The rope passing through the line hole is guided by the cooperation of the line pulley and the winding wheel, which is conducive to reducing the probability of contact friction between the rope and the inner edge of the line hole, ensuring that the rope retracted and released by the winding wheel can pass through the line hole smoothly, making the retraction and release smooth and reducing the failure rate.

[0010] In the aforementioned swing handle device for a sunshade hanging umbrella, the upright column comprises a vertically disposed column and an adjustment seat that can slide up and down along the column and be positioned. One end of the inclined rod is hingedly connected to the adjustment seat, and the inclined rod can swing up and down relative to the adjustment seat. As the adjustment seat slides up and down relative to the column, the angle and height of the inclined rod can be adjusted, thereby adjusting the state of the sunshade hanging umbrella and ensuring convenient use.

[0011] In the aforementioned sunshade umbrella handle device, a sleeve is provided at one end of the diagonal rod. The sleeve, the diagonal rod, and the adjustment seat are coaxially hinged. The sleeve protects the diagonal rod and the adjustment seat by enclosing the sharp edges of the diagonal rod, thereby protecting the diagonal rod and the adjustment seat. The sleeve and the diagonal rod are coaxially hinged with the adjustment seat. This connection of the diagonal rod, the sleeve, and the adjustment seat via the same rotational axis reduces the impact of assembly tolerances on stability and minimizes shaking of the diagonal rod.

[0012] In the aforementioned swing handle device for a parasol, the edge of the clearance notch includes a flange that can restrict the diagonal rod from escaping from the clearance notch, and the flange protrudes inwardly of the clearance notch. By providing the flange protruding inwardly of the clearance notch at the edge of the clearance notch, the flange cooperates with the outer circumference of the diagonal rod to restrict the diagonal rod from escaping from the clearance notch. This enhances the stability of the connection between the swing handle housing and the diagonal rod during use, and simultaneously provides a positioning function during assembly of the first and second half shells, thereby improving installation convenience and facilitating maintenance.

[0013] In the aforementioned sunshade umbrella handle mechanism, both the first and second half shells have rotating grooves, which are coaxially opposed. The ends of the spool assembly rotate and fit within the grooves. These two rotating grooves ensure the spool assembly's stable position. During maintenance, whether the first or second half shell is disassembled, the spool assembly is prevented from dislodging, facilitating maintenance.

[0014] In the hand-cranking device of the above-mentioned sunshade parasol, a through hole communicating with the outside is formed at the bottom of the rotating groove on the first half shell. The through hole is coaxially arranged with the rotating groove, and one end of the wire wheel assembly is inserted into the through hole. This facilitates the user to drive the wire wheel assembly to rotate from the outside, ensuring convenient use.

[0015] In the hand-cranking device of the above-mentioned sunshade parasol, the wire wheel assembly further includes a hand-cranking shaft capable of driving the wire winding wheel to rotate. The hand-cranking shaft is coaxially arranged with the wire winding wheel. A check spring for preventing the wire winding wheel from rotating by itself is provided between one end of the hand-cranking shaft and the end face of the wire winding wheel. A metal bushing is sleeved on the outer periphery of the other end of the hand-cranking shaft, and the metal bushing is embedded in the through hole. After the check spring is provided, after the user controls the wire winding wheel to wind and unwind the wire rope in place through the hand-cranking shaft, the wire winding wheel can be locked and restricted by the check spring to prevent the wire winding wheel from rotating by itself, avoiding the failure of adjustment. At the same time, a metal bushing is sleeved on the outer periphery of the other end of the hand-cranking shaft, and the metal bushing is embedded in the through hole, so that the wear on the first half shell caused by the rotation of the hand-cranking shaft can be reduced. In the later stage, only the metal bushing needs to be replaced for maintenance, and the maintenance cost is low and convenient.

[0016] In the hand-cranking device of the above-mentioned sunshade parasol, a pull rod is hinged between the inclined rod and the upright column. There are two pull rods, and one ends of the two pull rods are respectively located on both sides of the upright column, and the other ends of the two pull rods are respectively located on both sides of the middle section of the inclined rod. Such a setting makes the umbrella body structure more stable on the premise of ensuring the adjustment function of the inclined rod, and greatly improves the wind resistance of the sunshade parasol.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] When maintenance is required due to a malfunction of the hand-cranking device in the hand-cranking device of the present sunshade parasol, after the hand-cranking shell is disassembled from the inclined rod, no additional disassembly operation is required for the wire wheel assembly, and the connection relationship between the inclined rod and the upright column does not need to be changed, avoiding the phenomenon of difficult reset due to torque influence after the inclined rod is disassembled, greatly reducing the workload and difficulty of maintenance disassembly, and improving the convenience of repairing the hand-cranking device.

[0032] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0033] Such as Figure 1-7As shown in the figure, in the hand crank device of this sunshade hanging umbrella, the sunshade hanging umbrella includes a vertical column 1 and an inclined rod 2 for supporting the umbrella ribs and the umbrella surface. The inclined rod 2 is in a hollow tubular shape, and a cord 9 is passed through the inner cavity of the inclined rod 2. The upper surface of the hand crank housing 3 has a relief notch 31 communicating with the inner cavity of the hand crank housing 3. One end of the inclined rod 2 is connected to the vertical column 1, and the lower surface of the inclined rod 2 has a wire passing hole 21 communicating with the inner cavity of the inclined rod 2. The side part of the inclined rod 2 is embedded in the relief notch 31, and the part of the inclined rod 2 with the wire passing hole 21 is located in the inner cavity of the hand crank housing 3. The inclined rod 2 and the hand crank housing 3 are detachably connected by screws. The wire passing hole 21 communicates with the relief notch 31. The wire wheel assembly 4 is rotatably connected between the inner cavity side walls of the hand crank housing 3 and is located outside the inclined rod 2. The cord 9 passes out from the wire passing hole 21 and is connected to the wire wheel assembly 4. The vertical column 1 of the sunshade hanging umbrella provides a supporting function for the entire umbrella frame. The hollow inclined rod 2 is used to support and suspend the umbrella ribs and the umbrella surface. The inner cavity of the inclined rod 2 can allow the cord 9 to pass through to control the opening and closing of the umbrella ribs. The wire wheel assembly 4 of the hand crank device can drive the rotation to drive the cord 9 to be wound and unwound and locked, realizing the convenient control of the opening and closing of the umbrella surface. The hand crank housing 3 provides decoration and protection for the wire wheel assembly 4. When using the hand crank device, the hand crank housing 3 is fixed on the inclined rod 2, and the wire wheel assembly 4 is rotated to wind and unwind the cord 9. The cord 9 winds and unwinds through the wire passing hole 21 and enters and exits the inner cavity of the inclined rod 2, realizing the control of the cord 9 by the wire wheel assembly 4. When maintaining the hand crank device, the hand crank housing 3 can be directly detached from the inclined rod 2. Since the wire wheel assembly 4 is installed in the hand crank housing 3 and is located outside the inclined rod 2, that is, the wire wheel assembly 4 is only connected to the hand crank housing 3 and is not connected to the inclined rod 2, no additional disassembly operation is required for the wire wheel assembly 4 when the hand crank housing 3 is detached. Moreover, the inclined rod 2 is directly connected to the vertical column 1, rather than being connected to the vertical column 1 through the hand crank device. During the process of detaching the hand crank device from the inclined rod 2 for maintenance, the connection relationship between the inclined rod 2 and the vertical column 1 does not need to be changed, avoiding the phenomenon that it is difficult to reset due to the torque effect after detaching the inclined rod 2, greatly reducing the workload and difficulty of maintenance disassembly. Therefore, the hand crank device of this sunshade hanging umbrella improves the convenience of maintenance while not affecting the control of the cord 9 winding and unwinding by the hand crank device. Further, the hand crank housing 3 includes a half shell one 32 and a half shell two 33 that are detachably connected by screws. The wire wheel assembly 4 is located between the half shell one 32 and the half shell two 33. The half shell one 32 and the half shell two 33 are buckled to form the relief notch 31, and the half shell one 32 and the half shell two 33 are respectively detachably connected to the left and right sides of the inclined rod 2. In this way, when only the wire wheel assembly 4 has problems, the user can separately detach the half shell one 32 or the half shell two 33, and the complete wire wheel assembly 4 can be exposed for maintenance, greatly improving the maintenance convenience.The reel assembly 4 includes a winding wheel 41 for storing the rope 9. A wire passing pulley 5 is rotatably connected between the left and right side walls of the inner cavity of the inclined rod 2. The axis of the wire passing pulley 5 is parallel to the axis of the winding wheel 41. The wire passing hole 21 is located between the wire passing pulley 5 and the winding wheel 41. The rope 9 between the wire passing pulley 5 and the winding wheel 41 is spaced apart from the inner edge side wall of the wire passing hole 21. By arranging a rotatably connected line pulley 5 on the side wall of the inner cavity of the inclined rod 2, the rope 9 rests on the wheel groove of the line pulley 5, so that the line pulley 5 guides the rope 9 in the inner cavity of the inclined rod 2 so that it is adapted to the length direction of the inclined rod 2, and the axis of the line pulley 5 is parallel to the axis of the winding wheel 41, and the line hole 21 is located between the line pulley 5 and the winding wheel 41. The rope 9 passing through the line hole 21 is guided by the cooperation of the line pulley 5 and the winding wheel 41, and the rope 9 at this place is spaced apart from the inner edge of the line hole 21. In this way, it can be ensured that the rope 9 retracted and released by the spool assembly 4 can pass through the line hole 21 smoothly, avoid friction interference with the edge of the line hole 21, make the retraction and release smooth, and reduce the failure rate. Preferably, the edge of the clearance notch 31 has a flange 311 protruding toward the inside of the clearance notch 31. The flange 311 engages with the outer circumference of the diagonal rod 2 in a direction in which the diagonal rod 2 exits the clearance notch 31. By providing the flange 311 protruding toward the inside of the clearance notch 31 at the edge of the clearance notch 31, the flange 311 engages with the outer circumference of the diagonal rod 2 in a direction in which the diagonal rod 2 exits the clearance notch 31. This strengthens the connection stability between the handle housing 3 and the diagonal rod 2, while also providing a positioning function during assembly of the first and second half shells 32, 33, thereby improving installation convenience. Both the first and second half shells 32, 33 have rotation grooves 34, which are coaxially opposed. The two ends of the spool assembly 4 are rotatably engaged within the two rotation grooves 34. In this way, the two rotating grooves 34 can ensure the stable position of the reel assembly 4. During maintenance, whether half shell 1 32 or half shell 2 33 is disassembled, the reel assembly 4 will not be dislocated after disassembly, making maintenance convenient. A through hole 321 is provided at the bottom of the rotating groove 34 on half shell 1 32, which is connected to the outside world. The through hole 321 is coaxially arranged with the rotating groove 34, and one end of the reel assembly 4 is inserted into the through hole 321. This makes it convenient for the user to drive the reel assembly 4 to rotate from the outside, ensuring convenient use. The reel assembly 4 includes a winding wheel 41 and a crank shaft 42 that can drive the winding wheel 41 to rotate. The crank shaft 42 is coaxially arranged with the winding wheel 41. A retaining spring 43 is provided between one end of the crank shaft 42 and the end face of the winding wheel 41 to prevent the winding wheel 41 from rotating on its own. The other end of the crank shaft 42 is sheathed with a metal bushing 44. The metal bushing 44 is a copper bushing and is embedded in the through hole 321. After the anti-retraction spring 43 is set, the user can control the winding wheel 41 to retract and release the rope 9 by shaking the hand shaft 42. The anti-retraction spring 43 can be used to lock and limit the winding wheel 41 to prevent the winding wheel 41 from rotating and avoid adjustment failure.Meanwhile, a metal bushing 44 is sleeved around the outer periphery of the other end of the hand-cranking shaft 42, and the metal bushing 44 is embedded in the through hole 321. In this way, the wear caused by the rotation of the hand-cranking shaft 42 to the half shell 32 can be reduced. In later maintenance, only the metal bushing 44 needs to be replaced, and the maintenance cost is low and convenient.

[0034] As Figure 1 , Figures 3-6 , Figure 8 shown, the column 1 includes a vertically arranged column body 11 and an adjusting seat 12 that can slide up and down along the column body 11 and be positioned. One end of the inclined rod 2 is hinged to the adjusting seat 12 and can swing up and down relative to the adjusting seat 12. In this way, when the adjusting seat 12 slides up and down relative to the column body 11, the angle and the extended length of the inclined rod 2 can be adjusted, so as to adjust the state of the sunshade parasol and ensure convenient use. Further, the sunshade parasol further includes a limit pin 8. A plurality of vertically spaced limit grooves are provided on the column. After the adjusting seat 12 is adjusted to the specified height position, the limit pin 8 can be controlled to be inserted and matched with any one of the limit grooves of the column 1 to provide vertical support and limit for the adjusting seat 12 and ensure the stable position of the adjusting seat 12. A sleeve member 6 is sleeved on one end of the inclined rod 2. The sleeve member 6, the inclined rod 2 and the adjusting seat 12 are coaxially hinged. By providing that a sleeve member 6 is sleeved on one end of the inclined rod 2, the sleeve member 6 can wrap the sharp edges and corners at the end of the inclined rod 2, form protection for the end of the inclined rod 2 and the adjusting seat 12, and enable the sleeve member 6 and the inclined rod 2 to be jointly hinged to the adjusting seat 12 on the same rotation axis. In this way, the influence of assembly tolerance on stability is reduced, and the phenomenon of shaking of the inclined rod 2 can be reduced. A pull rod 7 is hinged between the inclined rod 2 and the column 1. There are two pull rods 7, and one ends of the two pull rods 7 are respectively located on both sides of the column 1, and the other ends of the two pull rods 7 are respectively located on both sides of the middle section of the inclined rod 2. Such a setting makes the umbrella body structure more stable on the premise of ensuring the adjustment function of the inclined rod 2, and greatly improves the wind resistance of the sunshade parasol.

[0035] The specific embodiments described herein are only illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
