Description

Technical Field

[0001] This utility model relates to the technical field of sunshade accessories, and in particular to a sunshade machine head assembly that is easy to connect. Background Technology

[0002] Existing retractable awnings have automatic or manual retraction functions. Manually retractable awnings generally require a manual head assembly for adjustment. This head assembly includes a worm gear box and an operating lever. The worm gear has a rotating shaft protruding from its core that engages with the awning. When the worm gear rotates, it drives the rotating shaft to rotate to roll up or release the awning fabric. The worm is generally vertically positioned, and an adjustment block extends downward from the bottom of the worm. The side of the adjustment block has an adjustment hole. The head of the operating lever is bent to form an insertion section that engages with the adjustment hole.

[0003] The aforementioned head assembly is typically located on the awning near the shade cloth, making it difficult to reach directly. Therefore, the operating lever is designed as a long handle. When not in use to adjust the shade cloth, the lever is usually removed and stored separately, making the awning look cleaner. When using the head assembly, a person needs to hold the operating lever and stand directly below the adjustment block. During operation, the person must keep their head up, looking at the relative position of the adjustment hole and the head of the operating lever, while simultaneously adjusting the position of the end of the lever. Since the opening of the adjustment hole is located on the side wall of the adjustment block, inserting the operating lever... The two parts must be aligned in the adjustment hole. However, the opening of the adjustment hole is not facing the human eye, making it difficult to determine the orientation of the adjustment hole by observation. Furthermore, when the head of the operating rod is close to the adjustment hole, it can easily block the adjustment hole, making it difficult to determine whether the head of the operating rod is aligned with the adjustment hole. This makes it difficult to insert the head of the operating rod into the adjustment hole, requiring multiple alignment attempts. After each failed insertion, the position of the adjustment hole and the head of the operating rod must be re-observed and aligned again. This process must be repeated multiple times until the head of the operating rod is successfully inserted into the adjustment hole before adjustment can begin. Therefore, the existing awning machine head assembly has the disadvantage of being cumbersome to connect. Utility Model Content

[0004] The existing awning machine head assembly requires multiple alignment operations before the operating lever and adjusting block can be connected, which is cumbersome. The purpose of this utility model is to provide an awning machine head assembly that is easy to connect.

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

[0006] A conveniently dockable awning head assembly includes a housing. A worm gear component and a worm assembly are fitted inside the housing. An adjusting block extends along the worm gear component's axis. An operating rod is docked to the adjusting block. A docking mechanism is provided between the adjusting block and the operating rod. The docking mechanism includes a receiving groove at the end of the adjusting block facing away from the worm gear component, and a mating joint at the end of the operating rod that engages with the receiving groove. A slider is movably disposed within the mating joint. A pawl is connected to the slider, expanding or contracting with its movement. After expansion, the pawl engages with the adjusting block and drives it to rotate with the mating joint. The expansion or contraction of the pawl is controlled by a drive mechanism. The drive mechanism includes an opening / closing structure that drives the pawl to open or close when it follows the slider, and a drive component that drives the slider to move, thereby moving the pawl.

[0007] With the above solution, the machine head assembly is set on the top of the sunshade, and the adjusting block is set downwards for easy operation. In this embodiment, the opening of the receiving slot faces away from the machine head, that is, it is located at the downward end of the adjusting block. When a person looks up at the adjusting block, they can directly see the receiving slot and its orientation. Moreover, the opening direction of the receiving slot is consistent with the axial direction of the worm gear component, both of which are vertically downwards. This can be known without observation, which significantly reduces the difficulty of observation and helps to align the connector with the receiving slot when adjusting the operating lever.

[0008] Preferably, the end of the connector has an inclined surface for guiding the connector into the receiving groove.

[0009] Using the above method, the guiding effect of the inclined surface can assist the connector in being inserted into the receiving groove. As long as the inclined surface on the connector is against the opening of the receiving groove, the operating rod can be slightly raised to guide the connector to be aligned with the receiving groove. Then, the operating rod can be raised further to guide the connector into the receiving groove, which significantly reduces the difficulty of operation.

[0010] Preferably, the connector has a movable cavity for accommodating the pawl and guiding the slider to slide. The side wall of the movable cavity has a movable groove extending to the outside of the connector. One end of the pawl is hinged to the slider. The opening and closing mechanism includes a shaft disposed in the movable cavity and parallel to the hinge axis between the pawl and the slider, and a guide hole on the pawl for the shaft to pass through.

[0011] Preferably, the driving component includes a first driving member that drives the pawl to expand and a second driving member that drives the pawl to retract.

[0012] Preferably, the active cavity has an opening at one end facing the receiving groove, and the first driving member includes a magnetic metal block embedded in the bottom of the receiving groove and a magnet fixedly installed at the end of the slider near the opening, which drives the slider to approach the metal block when the connector is inserted into the receiving groove.

[0013] Preferably, the opening shown has a retaining ring formed therein for the slider to abut against and restrict its disengagement from the movable cavity.

[0014] Preferably, the second driving member includes an elastic element that drives the slider away from the metal block. The elastic element includes a spring disposed between the retaining ring and the slider, and the slider is provided with a groove for the spring to be inserted.

[0015] Preferably, the side wall of the adjusting block is provided with a clearance hole that extends into the receiving groove, so that the pawl can be inserted into the clearance hole when it expands, allowing the adjusting block to rotate with the connector.

[0016] Using the above scheme, when the slider moves, the pawl can expand or contract by relying on the relative sliding of the guide groove and the shaft. When the connector is inserted into the receiving groove, the magnet can drive the slider to approach the metal block. At this time, the hinge end of the pawl and the slider approaches the shaft, and the pawl expands outward. After the adjustment is completed, the operating rod needs to be removed. At this time, simply pull out the operating rod. During this process, the slider will resist the retaining ring to prevent the magnet from extending out of the moving cavity due to magnetic attraction. When it is pulled out until the spring force exceeds the magnetic attraction force of the magnet, the spring drives the slider to move in the opposite direction. At this time, the hinge end of the pawl and the slider moves away from the shaft, and the pawl contracts inward.

[0017] This utility model has significant technical effects due to the adoption of the above technical solutions: the machine head assembly is set on the top of the sunshade, and the adjusting block is set downwards for easy operation. In this embodiment, the opening of the receiving groove faces away from the machine head, that is, it is located at the downward end of the adjusting block. When a person looks up at the adjusting block, they can directly see the receiving groove and its orientation. Moreover, the opening direction of the receiving groove is consistent with the axial direction of the worm gear component, both of which are vertically downwards. It can be known without observation, which significantly reduces the difficulty of observation and helps to align the connector with the receiving groove when adjusting the operating lever.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example

[0026] A quick-connect head assembly, based on Figure 1 , 4 As shown, the device includes a housing 1, inside which a worm gear component 2 and a worm component 3 are fitted together. A drive shaft 4 protrudes from the center of the worm gear component 2. An adjusting block 5 extends along the worm component 3 along its own axis. An operating lever 7 is connected to the adjusting block 5. The above is the prior art and will not be described in detail in this embodiment.

[0027] The improvement in this embodiment is that a docking mechanism is provided between the adjusting block 5 and the operating lever 7, according to... Figure 2 , 4 As shown in Figure 5, the docking mechanism includes a receiving groove 6 opened at one end of the adjusting block 5 facing away from the worm gear component 3 and along the axial direction of the worm gear component 3. The end of the operating rod 7 is provided with a connector 8 that is inserted into the receiving groove 6. The end of the connector 8 facing the receiving groove 6 is formed with an inclined surface 9 for guiding the connector 8 into the receiving groove 6 when the connector 8 is inserted into the receiving groove 6. The connector 8 is provided with a pawl 10 that can expand or contract. The adjusting block 5 is provided with a mating structure that can cooperate with the expanded pawl 10 so that the adjusting block 5 can rotate with the connector 8. In this embodiment, the mating structure includes a movable groove 12 opened on the side wall of the connector 8 for the pawl 10 to expand to the outside of the connector 8. The side wall of the receiving groove 6 is provided with a clearance hole 11 that penetrates to the inner wall. When the connector 8 is inserted into the adjusting block 5, the pawl 10 expands outward and inserts into the movable groove 12, so that the adjusting block 5 rotates with the connector 8.

[0028] The connector 8 has a movable cavity 13 formed within it to accommodate the expansion or contraction of the pawl 10. A slider 14 is guided within the movable cavity 13. The movable cavity 13 contains a drive mechanism that drives the pawl 10 to expand or contract. The drive mechanism includes an opening and closing structure that drives the pawl 10 to open or close when it moves with the slider 14. Figure 4 , 5As shown, the opening and closing structure includes a pawl 10 hinged to the slider 14 at its end, and a shaft 16 disposed within the movable cavity 13. The shaft 16 is parallel to the hinge axis between the pawl 10 and the slider 14. A guide groove 15 is provided on the pawl 10 for the shaft 16 to pass through. When the slider 14 moves, the pawl 10 can expand or contract by relying on the relative sliding of the guide groove 15 and the shaft 16. When the hinge end of the pawl 10 and the slider 14 approaches the shaft 16, the pawl 10 expands outward; when the hinge end of the pawl 10 and the slider 14 moves away from the shaft 16, the pawl 10 contracts inward. Figure 2 As shown, in this embodiment, the shaft 16 is a bolt that passes through the outer wall of the connector 8 into the movable cavity 13, and the small end of the bolt is fixed on the inner wall of the movable cavity 13.

[0029] The drive mechanism also includes a drive component that guides the slider 14 to slide, according to Figure 4 , 5 As shown, in this embodiment, the movable cavity 13 has an opening at one end facing the receiving groove 6. A magnet 17 is fixedly installed at the end of the slider 14 near the opening. A magnetic metal block 18 is embedded at the bottom of the receiving groove 6. When the connector 8 is inserted into the receiving groove 6, the magnet 17 approaches and attracts the metal block 18. The slider 14 is driven by the magnet 17 to approach the metal block 18. During this process, the hinge axis between the pawl 10 and the slider 14 approaches the shaft 16, and the pawl 10 expands outward. The driving structure also includes a second driving member that drives the slider 14 to retract the pawl 10. The second driving member includes an elastic member 19 that drives the slider 14 away from the metal block 18. Figure 4 , 5 As shown, in this embodiment, a retaining ring 20 is formed at the opening of the connector 8 to abut against the slider 14. When the connector 8 is disengaged from the receiving groove 6, the slider 14 will abut against the retaining ring 20 and will not extend out of the connector 8 due to the magnetic attraction of the first magnet 17. The elastic element 19 is a spring disposed between the retaining ring 20 and the slider 14. The end face of the slider 14 is provided with a groove 21 for the spring to be filled. When the connector 8 is disengaged from the receiving groove 6, the elastic element 19 drives the slider 14 away from the metal block 18. During this process, the hinge axis of the pawl 10 and the slider 14 moves away from the shaft 16, causing the pawl 10 to retract.

[0030] Based on the above structure, refer to Figures 1-5 The following describes the method of using a conveniently connected sunshade awning assembly in this embodiment:

[0031] When installing the operating lever 7, first lift the operating lever 7 so that the inclined surface 9 on the connector 8 is close to the opening of the receiving groove 6. With the inclined surface 9 abutting against the edge of the opening of the receiving groove 6, continue to lift the operating lever 7 so that the connector 8 can be inserted into the receiving groove 6. When the connector 8 is close to the bottom of the receiving groove 6, the first magnet 17 attracts the second magnet 17. The second magnet 17 drives the slider 14 to move. At this time, the hinge of the slider 14 and the pawl 10 is close to the shaft 16. The pawl 10 opens outward during the sliding process relative to the shaft 16. Then rotate the operating lever 7. When it is rotated to the point where the clearance hole 11 is aligned with the movable groove 12, the pawl 10 opens outward and passes through the clearance hole 11 and the movable groove 12 at the same time, completing the adjustment.

[0032] When removing the operating lever 7, simply pull it out. At this time, the slider 14 abuts against the retaining ring 20, preventing the magnet 17 from extending out of the movable cavity 13 due to magnetic attraction. When it is pulled out until the spring force exceeds the magnetic attraction force of the magnet 17, the spring drives the slider 14 to move in the opposite direction. At this time, the hinge end of the pawl 10 and the slider 14 moves away from the shaft 16, and the pawl 10 retracts inward. Figure 4 As shown, if the magnetic force of magnet 17 is large, during the pulling process, pawl 10 will abut against the inner wall of clearance hole 11 and retract inward under the squeezing action of clearance hole 11. The squeezing force and the elastic force of spring form a combined force to drive pawl 10 to retract. After pawl 10 retracts, connector 8 can completely disengage from adjustment block 5.

[0033] The machine head assembly is located at the top of the sunshade, with the adjusting block 5 facing downwards for easy operation. In this embodiment, the opening of the receiving groove 6 faces away from the machine head, i.e., it is located at the downward-facing end of the adjusting block 5. When a person looks up at the adjusting block 5, the receiving groove 6 can be seen directly. Since the opening direction of the receiving groove 6 is consistent with the distribution of the worm gear component 3, both being vertically downwards, it can be known without observation, significantly reducing the difficulty of observation. The inclined surface 9 at the end of the connector 8 has a guiding function. As long as the inclined surface 9 on the connector 8 abuts against the opening of the receiving groove 6, the connector 8 can be guided to align with the receiving groove 6, and then guided for insertion, significantly reducing the difficulty of operation.

[0034] After the connector 8 is inserted into the receiving groove 6, the interaction between the magnet 17 components drives the pawl 10 to expand outward and abut against the inner wall of the receiving groove 6. At this time, rotate the operating rod 7 to align the pawl 10 with the clearance hole 11 and allow the pawl 10 to expand to the outside of the clearance hole 11. Then, rotating the operating rod 7 will drive the adjusting block 5 and the worm gear to rotate with the operating rod 7 for adjustment.

[0035] 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. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
