The base frame is raised above the jasmine tree tops, allowing the sunshade to move across rows in the field, preventing the frame from rubbing against the branches. The two wheelless fixed legs extend outwards from the base frame, increasing the ground contact area and improving stability. The flat tarpaulin forms a trapezoidal covering structure with the horizontal struts and tarpaulin struts, effectively reducing lateral wind resistance compared to traditional pointed roof designs.

Description

Technical Field

[0001] This utility model relates to the technical field of portable sunshades, and more particularly to a three-legged portable sunshade for picking jasmine flowers. Background Technology

[0002] Existing jasmine field shade structures mostly employ steel pipe fixed supports and pointed canopy structures. Their four-legged rectangular bases or integral frame designs result in heavy (nearly 50 kg) and bulky equipment, making them difficult to move flexibly between narrow field rows. This often requires multiple people to carry them, significantly limiting operational efficiency. Furthermore, the pointed canopy, due to its prominent height and large windward area, is prone to tipping over in the field, posing a safety hazard. While traditional four-legged support structures offer better stability, their large footprint makes them susceptible to rubbing against the jasmine tree tops, affecting plant growth. Additionally, fixed welded frames cannot be disassembled, leading to high transportation and storage costs and hindering adaptability to the needs of rotating operations across multiple fields. To address these issues, there is an urgent need for a lightweight, wind-resistant, and easily movable shade structure that can allow for cross-row operations to avoid crop damage, and whose optimized structure enables rapid assembly and disassembly while providing stable support, thus meeting the specific needs of jasmine harvesting.

[0028] Example 1

[0029] Reference Figures 1-7This is the first embodiment of the present invention, which provides a three-legged movable sunshade for picking jasmine flowers. The device includes a base component 100, which includes a base frame 101. A movable support leg 102 is installed on one side of the base frame 101, and at least two fixed support legs 103 are installed on the other end of the base frame 101. A support component 200 includes a vertical support rod 201 disposed on the base frame 101. A horizontal support rod 202 is provided at the top of the vertical support rod 201, and tarpaulin support rods 203 are provided at both ends of the horizontal support rod 202. A sunshade component 300 is disposed at the top of the support component 200. The movable support leg 102 is located on the central axis of the base frame 101, and the two ends of the horizontal support rod 202 are fixedly connected to the tarpaulin support rods 203.

[0030] The entire device is made of metal to reduce its weight, such as electrophoretic iron pipe or galvanized square tubing. The base frame 101 is rectangular, which is the optimal choice, but it can also be triangular or other polygonal. Taking a rectangular base frame 101 with two fixed legs 103 as an example, the movable leg 102 is positioned at the midpoint of one side of the base frame 101, and the fixed leg 103 is positioned on the side of the base frame 101 away from the movable leg 102. The fixed legs 103 extend from the base frame 101 to both sides, allowing the movable leg 102 to move across the furrows. The two fixed legs 103 extend from the base frame 101 to both sides, supporting the adjacent furrows on either side of the movable leg 102. The space between the fixed legs 103 and the movable leg 102 is the space to accommodate the jasmine tree. The overall weight of this device is low, allowing operators to lift the base frame 101 on the side with the fixed legs 103 with one hand for easy movement.

[0031] Furthermore, the heights of the movable support leg 102 and the fixed support leg 103 are approximately equal, and this height is greater than the height of the jasmine tree, so that the base frame 101 can be higher than the jasmine tree and move across the treetop, preventing the base frame 101 from getting caught on the branches.

[0032] Furthermore, the vertical support rod 201 is set perpendicularly to the base frame 101. The vertical support rod 201 is located at the midpoint of the two parallel sides of the base frame 101. One of the vertical support rods 201 is located above the movable outrigger 102. The height of the top of the vertical support rod 201 from the ground is determined according to the height of the operator, and it must be sufficient for the operator to stand comfortably below the horizontal support rod 202. The two ends of the horizontal support rod 202 are respectively connected and fixed to the two vertical support rods 201. The two ends of the horizontal support rod 202 are also provided with tarpaulin support rods 203 perpendicular to the horizontal support rod 202. The connection point between the tarpaulin support rod 203 and the horizontal support rod 202 is the midpoint of the tarpaulin support rod 203.

[0033] Furthermore, the sunshade component 300 includes a sunshade tarpaulin 301 mounted on the tarpaulin support rod 203, a connecting rope 302 between the sunshade tarpaulin 301 and the tarpaulin support rod 203, and a fixing rod 303 mounted on the side of the base frame 101. The connecting rope 302 passes through the sunshade tarpaulin 301 and connects to the tarpaulin support rod 203 and the fixing rod 303.

[0034] Because of the horizontal support rod 202 and the tarpaulin support rod 203, the top of the tarpaulin 301 can be laid flat on the tarpaulin support rod 203 when it is covered on this device. Compared with the pointed tarpaulin that only uses the horizontal support rod 202, the height can be reduced and the windward area can be reduced, thus reducing the probability of it being blown over by the wind. The bottom of the tarpaulin 301 can be fixed to the fixing rod 303 of the base frame 101 by the connecting rope 302, thereby forming a trapezoidal shading space, which can shade the jasmine tree while reducing the reflection of the jasmine flowers.

[0035] Furthermore, solar panels can be installed on the horizontal support rod 202 and the tarpaulin support rod 203. The solar panels can generate electricity while pressing down on the tarpaulin 301. At this time, fans and other equipment can be installed under the horizontal support rod 202 for more comfortable use.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that it provides a fixed three-legged movable sunshade: the base frame 101 includes at least two main frame rods 101a for mounting movable support legs 102 and fixed support legs 103. The two main frame rods 101a are of equal length and parallel to each other.

[0038] The movable support leg 102 includes a horizontal connecting rod 102a disposed on one side of the base frame 101. The horizontal connecting rod 102a is fixedly connected to two main frame rods 101a. Both ends of the horizontal connecting rod 102a extend out of the base frame 101 to form fixed rods 303. A fixed vertical support rod 102b is disposed at the midpoint of the horizontal connecting rod 102a, and a first movable wheel 102c is disposed at the bottom end of the fixed vertical support rod 102b. The wheel spacing of the movable wheel 102c is less than the width of the furrow.

[0039] The fixed support leg 103 includes a first mounting rod 103a disposed on the side of the base frame 101 away from the movable support leg 102, and a first vertical support rod 103b disposed at both ends of the first mounting rod 103a. The first mounting rod 103a is fixedly connected to two main frame rods 101a, and both ends of the first mounting rod 103a also extend out of the base frame 101. The length of the first mounting rod 103a is equal to that of the horizontal connecting rod 102a, and the first vertical support rod 103b contacts the ground vertically downward.

[0040] The horizontal connecting rod 102a is fixedly connected to the main frame rod 101a of the base frame 101, the fixed vertical support rod 102b is fixedly connected to the horizontal connecting rod 102a, the first mounting rod 103a is fixedly connected to the base frame 101, and the first vertical support rod 103b is fixedly connected to the first mounting rod 103a. When the device is on flat ground, the movable support leg 102 and the fixed support leg 103 support the base frame 101, and the heights of the movable support leg 102 and the fixed support leg 103 are approximately equal.

[0041] The vertical strut 201 includes a mounting sleeve 201a disposed on the horizontal connecting rod 102a and the first mounting rod 103a, and a vertical rod 201b disposed on the mounting sleeve 201a. The bottom end of the vertical rod 201b is inserted into the mounting sleeve 201a, and the top end of the vertical rod 201b is connected to the horizontal strut 202.

[0042] The remaining structure is the same as that in Example 1.

[0043] Example 3

[0044] Reference Figures 3-7 This is the third embodiment of the present invention. Unlike the first embodiment, this embodiment provides a detachable and retractable three-legged mobile sunshade: the base frame 101 includes several splicing rods 101b, and a first mounting member 101c is provided between each splicing rod 101b for connecting and fixing each splicing rod 101b. The splicing rods 101b are connected and fixed to each other to form a frame structure.

[0045] The first mounting component 101c can be a plate with through holes. Corresponding through holes are made on each splicing plate. During assembly, after the splicing rods 101b are roughly joined together, the first mounting component 101c is placed on both sides of the splicing rod 101b. Bolts are inserted through each first mounting component 101c and each splicing rod 101b, and then the nuts are tightened to secure them. Similarly, pins, clips, or similar structures can be used, as long as they can connect and secure each splicing rod 101b.

[0046] The movable support leg 102 includes a frame rotating seat 102d disposed on one side of the base frame 101, a rotating rod 102e disposed on the frame rotating seat 102d, and a second movable wheel 102f disposed at the bottom end of the rotating rod 102e; wherein, the frame rotating seat 102d is fixedly installed on the lower surface of the base frame 101, and the top end of the rotating rod 102e is rotatably connected to the base frame 101 through the frame rotating seat 102d.

[0047] By setting the frame rotating seat 102d, the movable support leg 102 can rotate around the base frame 101. The frame rotating seat 102d is provided with a baffle, which can limit the rotation angle of the rotating rod 102e. At this time, the movable support leg 102 has two states: released and retracted. In the released state, it is perpendicular to the ground. In the retracted state, it is parallel to the base frame 101 and stored inside the base frame 101, which can reduce the space occupied when retracted.

[0048] The fixed support leg 103 includes a plurality of second mounting members 103c disposed on the side of the base frame 101 away from the movable support leg 102, a second mounting rod 103e disposed on the second mounting member 103c, and a second vertical support rod 103f disposed at the upper end of the second mounting rod 103e; wherein, the second mounting member 103c is used to detachably connect and fix the second mounting rod 103e to the base frame 101, and the second vertical support rod 103f is vertically connected and fixed to the second mounting rod 103e through an angle plate.

[0049] The second mounting component 103c is similar to the first mounting component 101c, and can also be a plate with through holes, used to connect and fix the second mounting rod 103e to the splicing rod 101b of the base frame 101. The second mounting rod 103e can also be provided with a socket at the end connected to the splicing rod 101b, for installing mounting pins 103d to reinforce the second mounting rod 103e. The second vertical rod 201b also adopts a similar structure to fix it to the second mounting rod 103e.

[0050] The vertical strut 201 includes an insertion sleeve 201c disposed on the base frame 101, a folding rod 201d disposed in the insertion sleeve 201c, and a top rotating seat 201e disposed at the top of the folding rod 201d; wherein, at least two insertion sleeves 201c are provided and are located on the central axis of the base frame 101, the bottom end of the folding rod 201d is inserted into the insertion sleeve 201c, and the top end of the folding rod 201d is rotatably connected to the horizontal strut 202 through the top rotating seat 201e.

[0051] The insertion sleeve 201c is fixed on the base frame 101. When in use, the bottom end of the folding rod 201d is inserted into the insertion sleeve 201c for connection and fixation. When not in use, the folding rod 201d can be rotated and stored through the top rotating seat 201e. In the hand-pressed state, the folding rod 201d is parallel to the horizontal support rod 202 and located below the horizontal support rod 202.

[0052] With the above settings, the device can be easily disassembled and folded when not in use, thus saving a lot of space, and can also be quickly assembled when in use.

[0053] The remaining structure is the same as that in Example 1.
