Description

Technical Field

[0001] This utility model relates to the technical field of sunshade accessories, and in particular to a handle and a sunshade drive head assembly. Background Technology

[0002] Chinese Patent CN208441536U discloses a non-powered swimming pool sunshade, including a frame and a sunshade net laid on top of the frame. The frame is equipped with a transmission device for storing or unfolding the sunshade net. The transmission device includes a driving part and a driven part. The driving part includes a rotating shaft at the top of the frame for the sunshade net to be wound around, and driving wheels at both ends of the rotating shaft. A driving head is connected to one of the driving wheels. The driving head includes a worm gear component and a worm component that cooperate with each other, and a housing covering the worm gear component and the worm component. The worm gear component is coaxial with the rotating shaft and rotates synchronously. A docking block is provided at the end of the worm component along its own axial direction. A hanging hole is opened on the docking block, and a handle is detachably connected to the hanging hole. After the handle is connected to the docking block, turning the handle can drive the worm to rotate, thereby driving the worm gear to rotate and drive the rotating shaft and the driving wheel to perform a winding or releasing action.

[0003] For details on the specific structure of the handle that mates with the existing drive head, please refer to the attached diagram in the instruction manual of this solution. Figure 1 As shown, the handle includes a straight rod, with a crank formed at the bottom of the straight rod that is offset from the rod. The top of the straight rod is bent to form a hook that can hook onto the hanging hole. The hook is formed by bending the head of the straight rod to one side and has a notch that can hook onto or detach from the connecting block. The advantage of this structure is that after the hook hooks onto the hanging hole, one hand needs to hold the straight rod and the other hand needs to hold the crank to rotate it. At this time, the outer wall of the hook will abut against the outer wall of the connecting block, driving the worm gear to rotate. In actual operation, it is impossible for the human hand to restrict the straight rod to the ideal axis. During the rotation, the straight rod will move to varying degrees. After the straight rod moves, it will rotate around the worm gear, causing the straight rod to generate centrifugal force, which further aggravates the movement of the straight rod. Therefore, when the human hand grips the straight rod, the hand needs to constantly adjust the grip posture according to the rotation state of the straight rod in order to stabilize the connection between the hook and the hanging hole. If the human hand fails to restrict the movement of the straight rod, the hook will easily detach from the hanging hole. Therefore, the handle used on the existing sunshade drive head still has room for improvement. Utility Model Content

[0004] The existing awning drive head handle requires constant fine-tuning of the hand grip according to the rotation state of the straight rod during use, otherwise the hook can easily detach from the hanging hole, resulting in inconvenience in operation. The primary objective of this utility model is to provide a handle that is less likely to detach from the drive head.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A handle includes a straight rod with a hook portion at the head and a rocker arm formed by a staggered bend at the bottom. The straight rod is centered relative to the hook portion. The hook portion includes a hook body with a notch, an opening and closing element movably disposed on the hook body, and a drive assembly for driving the opening and closing element to close the notch or to open the notch.

[0007] In this scheme, the straight rod on the handle is centered relative to the hook, allowing it to better align with the axis of the worm gear when rotating. This makes it easier for the user to control the movement of the straight rod and reduces the possibility of the handle coming off the hook. When the hook engages with the docking block, the opening and closing mechanism opens the notch to allow the hook body to engage with the hanging hole. The opening and closing mechanism then closes the notch, further preventing the hook from detaching from the docking block.

[0008] Preferably, the opening and closing element is rotatably mounted on the hook body, and the hook body has a mounting petal for the opening and closing element to rotate and connect. When the opening and closing element is rotated to near the notch, it stops rotating by pressing against the hook body.

[0009] Preferably, the end of the opening / closing member is formed with a first inclined surface, and the hook body is formed with a second inclined surface that abuts against the first inclined surface when the opening / closing member approaches the notch, restricting the opening / closing member from continuing to rotate.

[0010] Using the above scheme, the opening and closing components are integrated into the notch by using the first and second inclined surfaces to fit together.

[0011] Preferably, the drive assembly includes a pull member that drives the opening / closing member away from and opens the notch by tightening and pulling, and a reset member that drives the opening / closing member closer to and closes the notch when the pull member is relaxed.

[0012] Preferably, the pulling member is inserted into the straight rod and its end extends out of the hook body and is connected to the opening and closing member. The end of the pulling member away from the opening and closing member is connected to the operating end.

[0013] Preferably, the operating end includes a sliding hole located on the part of the straight rod away from the hook and an operating block that passes through the sliding hole and is connected to the pulling member.

[0014] Preferably, the reset element includes a torsion spring disposed between the opening / closing element and the mounting flap, which drives the opening / closing element to flip toward the notch.

[0015] Using the above solution, when operating the handle, people only need to pull the operating block to tighten it and pull the traction component to drive the opening and closing component to rotate and open the gap. At this time, the hook part can be hooked into the hanging hole. When the operating block is released, the elastic force of the torsion spring can drive the opening and closing component to rotate in the opposite direction to seal the gap and prevent the hook part from coming off.

[0016] The second objective of this utility model is to provide a sunshade awning machine head assembly, including a housing, in which a worm gear and a worm are fitted together. A drive shaft is provided on the worm gear, and a docking block is provided at one end of the worm along its own axis. A hanging hole is provided on the docking block, and a handle as described in any of the above solutions is fitted together on the docking block. When the opening and closing part is away from the notch, the hook body can engage with the hanging hole to achieve connection with the docking block.

[0017] Using the above solution, the handle in the awning machine head assembly rotates after engaging with the docking block. During rotation, the straight rod on the handle can better fit the circumference of the worm gear, reducing the handle's movement. The hook on the handle, after engaging with the docking block, can close the notch on the hook body with the help of the opening and closing parts, further preventing the handle from coming off the hook.

[0018] This utility model, by adopting the above technical solution, has significant technical effects: In this solution, the straight rod on the handle is centered relative to the hook part, so that the straight rod can better fit the axis of the worm gear when rotating. When a person holds the rotating straight rod, he can more easily control the movement of the straight rod and reduce the possibility of the handle coming off the hook; When the hook part is engaged with the docking block, the opening and closing mechanism is driven to open the notch, allowing the hook body to engage with the hook hole. Then, the opening and closing mechanism is driven to close the notch, which can further prevent the hook part from coming off the docking block. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] Example

[0029] A type of awning machine head assembly, according to Figure 2 , 6 As shown, the device includes a housing 1, inside which a worm gear 2 and a worm 3 are fitted together. A drive shaft 4 is mounted on the worm gear 2. One end of the worm 3 extends along its own axis and is fitted with a docking block 5. The docking block 5 is fitted with a hanging hole 6 and a handle. The handle includes a straight rod 7. The head of the straight rod 7 is fitted with a hook portion that engages with the hanging hole 6 on the docking block 5. The bottom of the straight rod 7 is bent at an offset to form a crank handle 8. The above is the prior art and will not be described in detail in this embodiment.

[0030] The improvement in this embodiment is that, according to Figure 3 As shown, the straight rod 7 is centered relative to the hook portion. The hook portion includes a hook body 9 with a notch. A mounting flap 10 is formed on the hook body 9. A closing element 11 is rotatably connected to the mounting flap 10. The closing element 11 can rotate to close the notch or rotate to open the notch. A limiting structure is formed between the hook body 9 and the closing element 11 to limit the maximum rotation stroke of the closing element 11. Figure 7 As shown, the limiting structure includes a first inclined surface 12 formed at the end of the opening and closing member 11, and a second inclined surface 13 formed on the hook body 9. When the opening and closing member 11 approaches the notch, the second inclined surface 13 can abut against the first inclined surface 12, restricting the opening and closing member 11 from continuing to rotate.

[0031] The rotation of the opening / closing element 11 is controlled by a drive assembly, according to... Figure 6 , 7 As shown, the drive assembly includes a pulling member 14 that tensions and pulls the opening / closing member 11 away from and opens the notch. The pulling member 14 passes through the straight rod 7 and its end extends out of the hook body 9 and connects to the opening / closing member 11. The end of the pulling member 14 away from the opening / closing member 11 is connected to an operating end. Figure 6 , 7As shown, a movable cavity 15 is formed inside the straight rod 7 for the pulling member 14 to pass through. The movable cavity 15 is connected to the hook body 9 and its opening faces the opening and closing member 11. The opening and closing member 11 has a connecting petal 17 for the pulling member 14 to connect to. The end of the pulling member 14 away from the opening and closing member 11 is connected to an operating end. The operating end includes a sliding hole 18 located at the part of the straight rod 7 away from the hook. In this embodiment, the sliding hole 18 is located at the part of the straight rod 7 located at the crank 8, and the sliding hole 18 is connected to and intersected with the movable cavity 15. An operating block 19 connected to the pulling member 14 passes through the sliding hole 18. When the pulling member 14 is released, the opening and closing member 11 is driven by a reset member to approach and close the notch. Figure 4 As shown, the reset member includes a torsion spring 20 disposed between the opening / closing member 11 and the mounting flap 10, which drives the opening / closing member 11 to flip and approach the notch.

[0032] Based on the above structure, refer to Figures 1-7 It can be seen that in this embodiment, the straight rod 7 on the handle is centered relative to the hook part, so that the straight rod 7 can better fit the axis of the worm gear 3 when rotating. When a person holds the rotating straight rod 7, he can more easily control the movement of the straight rod 7 and reduce the possibility of the handle coming off the hook. When the hook part cooperates with the docking block 5, the opening and closing part 11 is driven to open the notch so that the hook body 9 can be fastened into the hook hole 6. Then the opening and closing part 11 is driven to close the notch, which can further prevent the handle from coming off the hook.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
