[0022] Please refer to Figures 1-5This utility model provides a hand-cranked housing 100 for a straight umbrella pole. The hand-cranked housing 100 is fitted onto the pole body 200 of the straight umbrella pole and includes a mounting base 110, a fixing ring 300, a bottom ring, and a lamp body 400. The mounting base 110 is fixedly installed at the upper end of the hand-cranked housing 100 and is coaxially arranged with the pole body 200. The fixing ring 300 is used to support the lamp body 400 and is formed by two semi-circular ring-shaped connecting rings 310 coaxially joined together. Correspondingly, the bottom ring, as a positioning component that mates with the mounting base 110, is also formed by two semi-circular ring-shaped retaining rings 311 coaxially joined together. Each retaining ring 311 is coaxially fixedly connected to its corresponding connecting ring 310 at the bottom, thereby combining the fixing ring 300 and the bottom ring into a whole ring structure, making the mounting base 110, pole body 200, fixing ring 300, and bottom ring coaxial with each other to ensure the stability and balance of the structure.

[0023] Two lamp bodies 400 are installed on the circumferential surfaces of two semicircular connecting rings 310, respectively, to achieve surround lighting. To facilitate the easy fixing of the two independent semicircular connecting rings 310 into a complete ring during installation, a snap-fit ​​structure 330 is provided on the adjacent circumferential surfaces of the two connecting rings 310. This snap-fit ​​structure 330 can interlock and fix the two connecting rings 310 to prevent separation. Furthermore, a charging chamber 320 is provided on the upper part of the connecting rings 310 for charging the lamp body 400.

[0024] When the lamp body 400 needs to be inspected or replaced, simply unfasten the clip structure 330 on the connecting ring 310 to remove the two semi-circular connecting rings 310 from both sides of the umbrella pole, thus achieving quick removal of the entire lighting module. The entire process does not require disassembling the hand crank housing 100 itself, nor does it require disconnecting the hand crank housing 100 from the umbrella pole, greatly simplifying the maintenance process and realizing the independent disassembly and assembly function of the lamp body 400, thereby making maintenance operations more convenient.

[0025] The snap-fit ​​structure 330 in this embodiment can be the snap-fit ​​structure 330 commonly used in the prior art, and its specific structure and principle will not be described in detail here.

[0026] Reference Figure 2 , Figure 3 and Figure 4 The mounting bracket 110 is equipped with a locking assembly 600. The main function of the locking assembly 600 is to actively lock the axial position of the connecting ring 310 relative to the mounting bracket 110. When the bottom ring of the lighting module is inserted into the mounting bracket 110, the locking assembly 600 can securely lock the module in the predetermined working position, thereby further improving the stability of the lamp body 400 after installation and preventing it from accidentally axially loosening within the mounting bracket 110 due to gravity or external force.

[0027] Specifically, the locking assembly 600 includes a power component and a locking block 610. The interior of the locking base 110 has a radially extending movable groove 111, and the locking block 610 is slidably engaged with the movable groove 111. A through groove is provided through an inner sidewall of the movable groove 111 facing the central axis of the locking base 110. A positioning groove 312 is provided on the outer circumferential surface of the connecting ring 310. The locking block 610 can pass through the through groove and be inserted into the positioning groove 312. The power component is connected to the locking block 610 and is used to drive the locking block 610 to slide within the movable groove 111. After the retaining ring 311 is inserted into the retaining base 110, the retaining block 610 can be pushed to slide along the movable groove 111 by the power component, so that the retaining block 610 moves towards the positioning groove 312 until the retaining block 610 is inserted into the positioning groove 312. Since the moving direction of the retaining block 610 is radial along the retaining base 110, while the moving direction of the retaining ring 311 is axial along the retaining base 110, the retaining block 610 can limit the axial direction of the retaining ring 311, thereby locking the axial position of the retaining ring 311.

[0028] Furthermore, the power component includes a connecting rod 630 and a handle 640. A through hole is provided on the side of the movable groove 111 facing away from the through groove. One end of the connecting rod 630 is connected to the locking block 610, and the other end of the connecting rod 630 passes through the through hole and extends to the outside of the locking seat 110. The handle 640 is fixed to the end of the connecting rod 630. When disassembly is required, the operator pulls the handle 640, thereby driving the locking block 610 to move away from the positioning groove 312 through the connecting rod 630, so that the locking block 610 is disengaged from the positioning groove 312 to cancel the axial restriction on the retaining ring 311. At this time, the retaining ring 311 can be pulled out from the locking seat 110.

[0029] In other embodiments, the power component may also be a device with telescopic function in the prior art, such as an electric telescopic push rod, which is not limited here.

[0030] Furthermore, the power component also includes an elastic element, which is disposed within the movable groove 111 and located on the side of the locking block 610 facing away from the through groove. This elastic element provides a thrust to the locking block 610 toward the positioning groove 312. In its natural extension and retraction state, the elastic element continuously applies a thrust toward the locking block 610 in the direction of both the through groove and the positioning groove 312, thus enabling the locking block 610 to have an automatic locking function.

[0031] In this embodiment, the elastic element is a spring 620, which is sleeved on the outer peripheral surface of the connecting rod 630. When the operator pulls the handle 640 to move the locking block 610, the spring 620 is compressed. When the handle 640 is released, the spring 620 rebounds and pushes the locking block 610 towards the positioning groove 312 to achieve automatic locking. In other embodiments, the elastic element may also be made of other elastic materials, such as rubber gaskets, etc., which are not limited here.

[0032] Reference Figure 4 , Figure 5 and Figure 6 A limiting groove 112 is provided on the inner wall of the perforated part. A limiting strip 631 adapted to the limiting groove 112 is provided on the circumferential surface of the connecting rod 630. The connecting rod 630 is rotatably connected to the locking block 610, which can be achieved through a structure such as a bearing. When the operator needs to disassemble the lamp body 400, pulling the handle 640 moves the connecting rod 630 and the locking block 610 away from the positioning groove 312 until the limiting strip 631 on the surface of the connecting rod 630 disengages from the movable groove 111. Then, the handle 640 is rotated so that the handle 640 moves the connecting rod 630 and the limiting strip 631 away from the positioning groove 312. Rotate until the limiting strip 631 is misaligned with the limiting groove 112. When the handle 640 is released, the spring 620 rebounds, causing the limiting strip 631 to tightly abut against the outer wall of the card holder 110. At this time, the card block 610 cannot be inserted into the positioning groove 312 again, thus facilitating the removal of the two connecting rings 310 through the buckle structure 330. After removal, when the handle 640 is rotated, the limiting strip 631 and the limiting groove 112 are realigned. At this time, the limiting strip 631 will pass through the limiting groove 112 and re-enter the movable groove 111. At the same time, the card block 610 will also reset.

[0033] Reference Figure 4 The circumferential surface of the locking block 610 is provided with a retaining ring 611. The cross-sectional area of ​​the retaining ring 611 is larger than the cross-sectional area of ​​the through groove, and the retaining ring 611 is slidably adapted to the movable groove 111. The retaining ring 611 limits the movement distance of the locking block 610 to prevent the locking block 610 from completely disengaging from the movable groove 111 and to ensure stability.

[0034] Reference Figure 4 The upper surface of the locking block 610 is provided with an inclined surface, which is inclined from top to bottom away from the retaining ring 611. When the operator inserts the retaining ring 311 downward into the retaining seat 110, the bottom surface of the retaining ring 311 will contact the inclined surface of the upper surface of the locking block 610. At this time, due to the guidance of the inclined surface, the locking block 610 will slide into the movable groove 111. At this time, the locking block 610 will compress the spring 620. After the retaining ring 311 is inserted into place, the locking block 610 will correspond to the position of the positioning groove 312, so that the spring 620 has a springback space. After the spring 620 springs back, it can push the locking block 610 into the positioning groove 312, thereby locking after the retaining ring 311 is inserted, simplifying the installation operation.

[0035] Reference Figure 1 The hand-cranked shell 100 is equipped with a Bluetooth speaker 500, which further enriches the functionality and entertainment of the outdoor sun umbrella and enhances the user experience.

[0036] In summary, the working principle of this utility model is as follows: When the operator needs to install the lamp body 400, the two connecting rings 310 are wrapped around the rod body 200 and coaxially spliced, and then connected and fixed by the snap-fit ​​structure 330. Then, the connecting rings 310 are slid down so that the retaining ring 311 is inserted into the retaining seat 110. At this time, the bottom surface of the retaining ring 311 contacts the inclined surface of the upper surface of the retaining block 610. At this time, due to the guidance of the inclined surface, the retaining block 610 will be driven to slide into the movable groove 111. At this time, the retaining block 610 will compress the spring 620. When the retaining ring 31... 1. After insertion, the locking block 610 will correspond to the position of the positioning groove 312, giving the spring 620 room to rebound. After the spring 620 rebounds, it can push the locking block 610 into the positioning groove 312. Since the moving direction of the locking block 610 is radial along the locking seat 110, and the moving direction of the retaining ring 311 is axial along the locking seat 110, the locking block 610 can limit the axial direction of the retaining ring 311, thereby locking the axial position of the retaining ring 311.

[0037] When the lamp body 400 needs to be disassembled, pull the handle 640. The handle 640, through the connecting rod 630, moves the locking block 610 away from the positioning groove 312 until the locking block 610 disengages from the positioning groove 312. During the movement, the locking block 610 can compress the spring 620. After the operator pulls the handle 640 to disengage the limiting strip 631 on the circumferential surface of the connecting rod 630 from the movable groove 111, rotate the handle 640 to rotate the connecting rod 630 axially, so that the limiting strip 631 and the limiting groove 112 are circumferentially misaligned. Then release the handle 640. The rebound of the spring 620 will push the locking block 610 and the connecting rod 630 closer to the positioning groove. As the groove 312 moves, the limiting strip 631 will abut tightly against the circumferential outer wall of the card holder 110 due to the misalignment with the limiting groove 112, thereby causing the card block 610 to stay in the movable groove 111. At this time, the operator can remove the two connecting rings 310 through the buckle structure 330, and then pull the connecting rings 310 to remove the card rings 311 from the card holder 110, thus completing the disassembly of the lamp body 400. Therefore, it is not necessary to disassemble the hand crank housing 100 itself or disconnect the connection between the hand crank housing 100 and the umbrella pole during the entire process, which greatly simplifies the maintenance process and realizes the independent disassembly and assembly function of the lamp body 400, making it easier to perform maintenance operations.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
