Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, specifically to a portable sunshade. Background Technology

[0002] Currently, many medical institutions lack accessible pathways between buildings. Therefore, when patients need to be transferred between buildings during rainy weather, the transport vehicles must provide shelter from wind and rain. Portable sun umbrellas are common sun protection tools in modern life. They not only provide sun protection but also emphasize portability and practicality. These umbrellas typically have five-fold or six-fold designs, and the canopy can be easily folded into a compact size for easy carrying. This device is a great helper for summer outings, featuring portability, good sun protection, and diverse designs. When using it, attention should be paid to avoiding direct sunlight, regular cleaning, and proper use. The following problems exist with existing technologies:

[0003] Currently, ordinary medical transport trolleys do not have portable sunshades. In scorching sun or inclement weather, patients are exposed to the elements during transport, posing a significant challenge to nursing care. Existing portable sunshades lack a fixing mechanism, relying solely on a pole inserted into a hole in the transport trolley for stability. This limits their usability; in some trolleys where insertion is unsuitable or impossible, the sunshade is unusable. Furthermore, the lack of a fixing mechanism makes the existing sunshade susceptible to swaying or tipping due to external factors, potentially causing imbalance and injury to the user and those around them. Additionally, existing sunshades are bulky and inconvenient to carry, reducing their practicality. Moreover, the opening and closing angle of existing sunshades is not adjustable, making effective locking impossible and creating safety hazards. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A portable sun umbrella includes four outer poles, each with a fixed insert at its bottom and an inner pole fixed at its top. Each inner pole has a fixed limit block at its top, and each outer pole has a rotatable fixing component at its bottom outer wall. Each inner pole has a limit locking component on its outer wall. A folding umbrella assembly is rotatably connected between the four limit locking components, and a sunshade cloth is fixedly connected to the top of the folding umbrella assembly.

[0007] A further improvement of this utility model's technical solution is that: the fixing component includes a fixing plate, the side of the fixing plate near the outer sleeve rod is fixedly connected to the rotating sleeve, a motor is fixedly connected to the front side wall of the fixing plate, the output end of the motor extends through to the rear side wall of the fixing plate and is fixedly connected to a main gear, an incomplete gear is rotatably connected to the upper left corner of the rear side of the fixing plate, an incomplete gear is meshed with the lower part of the incomplete gear, the incomplete gear is rotatably connected to the fixing plate, the right side of the incomplete gear is meshed with the main gear, fixing rods are fixedly connected to the left side of the outer walls of both the incomplete gear and the incomplete gear, clamps are rotatably connected to the ends of the upper and lower fixing rods away from the incomplete gear, and two symmetrical upper and lower limiting rods are rotatably connected to the left sides of both the front and rear sides of the fixing plate, the ends of the upper and lower limiting rods away from the fixing plate are respectively rotatably connected to the middle of the upper and lower clamps.

[0008] A further improvement of the present invention is that the folding umbrella assembly includes a fixed vertical rod, a fixed sleeve 1 is fixedly connected to the top of the outer wall of the fixed vertical rod, a plurality of annularly distributed connecting rods 1 are rotatably connected to the outer wall of the fixed sleeve 1, a fixed sleeve 2 is fixedly connected to the bottom of the outer wall of the fixed vertical rod, a plurality of annularly distributed connecting rods 2 are rotatably connected to the outer wall of the fixed sleeve 2, and the end of the connecting rod 1 away from the fixed sleeve 1 is rotatably connected to the middle of the connecting rod 2.

[0009] A further improvement of this utility model is that: the limiting and locking assembly includes a sliding sleeve, the inner wall of the sliding sleeve is slidably connected to the outer wall of the inner sleeve rod, the outer wall of the sliding sleeve is rotatably connected to the end of the connecting rod two away from the fixed sleeve two, springs are fixedly connected to both the upper and lower sides of the outer wall of the sliding sleeve, a moving plate is fixedly connected to the end of the upper and lower two springs away from the sliding sleeve, a cylindrical iron block is fixedly connected to the middle of the side of the moving plate near the sliding sleeve, a plurality of limiting holes one are opened on the outer wall of the inner sleeve rod at equal intervals, a limiting hole two is opened on the outer wall of the sliding sleeve that is adapted to the size of the limiting hole one, the end of the cylindrical iron block away from the moving plate passes through the limiting hole two and the limiting hole one respectively and extends into the interior of the inner sleeve rod, and a vertically arranged electromagnet is fixedly connected inside the inner sleeve rod.

[0010] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0020] like Figure 1 , Figure 2 As shown, this utility model provides a portable sunshade umbrella, including four outer poles 10, each with a fixed insert 11 at its bottom, an inner pole 13 fixedly connected to its top, a limiting block 14 fixedly connected to the top of each of the four inner poles 13, a fixing component 2 rotatably connected to the bottom of the outer wall of each of the four outer poles 10, a limiting locking component 4 provided on the outer wall of each of the inner poles 13, a folding umbrella component 3 rotatably connected between the four limiting locking components 4, and a sunshade cloth 15 fixedly connected to the top of the folding umbrella component 3.

[0021] The four outer rods 10 have insertion rods 11 at the bottom that can be inserted into a medical transport bed to provide stable support for the sun umbrella. The limiting block 14 at the top of the inner rod 13 prevents the limiting locking component 4 from extending too far. The fixing component 2 is located at the bottom of the outer wall of the outer rod 10 and is used to fix the sun umbrella to the medical transport bed. The sunshade cloth 15 at the top serves to provide shade and protection from rain.

[0022] like Figure 3 As shown, the fixing assembly 2 includes a fixing plate 20. The side of the fixing plate 20 closest to the outer sleeve rod 10 is fixedly connected to the rotating sleeve 12. A motor 21 is fixedly connected to the front side wall of the fixing plate 20. The output end of the motor 21 passes through the rear side wall of the fixing plate 20 and is fixedly connected to the main gear 23. An incomplete gear 24 is rotatably connected to the upper left rear side of the fixing plate 20. An incomplete gear 27 is meshed below the incomplete gear 24. The incomplete gear 27 is rotatably connected to the fixing plate 20. The right side of the incomplete gear 24 is meshed with the main gear 23. Fixing rods 25 are fixedly connected to the left side of the outer walls of both the incomplete gear 27 and the incomplete gear 24. Clamping plates 26 are rotatably connected to the ends of the upper and lower fixing rods 25 away from the incomplete gear 24. Two symmetrical upper and lower limiting rods 22 are rotatably connected to the left sides of both the front and rear sides of the fixing plate 20. The ends of the upper and lower limiting rods 22 away from the fixing plate 20 are rotatably connected to the middle of the upper and lower clamping plates 26, respectively.

[0023] When it is necessary to fix the sunshade to the medical transport bed, if the medical transport bed is equipped with a hole that matches the insertion rod 11, the insertion rod 11 can be directly inserted into the hole of the medical transport bed. If there is no matching hole, the motor 21 in the fixing assembly 2 is activated. The output end of the motor 21 drives the main gear 23 to rotate. The main gear 23 meshes with the incomplete gear 24, causing the incomplete gear 24 to rotate. The incomplete gear 24 meshes with the incomplete gear 27 below, causing the incomplete gear 27 to rotate. The incomplete gear 24 and the incomplete gear 27... The fixing rod 25 on the left side of the outer wall of gear 27 rotates accordingly. The clamping plate 26 connected to the end of the upper and lower fixing rods 25 away from the incomplete gear 24 moves towards the middle under the restriction of the limiting rod 22, clamping the edge of the medical transport cart, thereby firmly fixing the sunshade in a specific position, greatly enhancing the stability of the sunshade during use. Even in severe weather conditions such as strong winds, the sunshade can maintain a stable state. At the same time, the fixing component 2 allows the sunshade to be fixed in any place on any type of hospital bed, improving the adaptability of the device.

[0024] like Figure 4 As shown, the folding umbrella assembly 3 includes a fixed vertical pole 30, a fixed sleeve 31 fixedly connected to the top of the outer wall of the fixed vertical pole 30, a plurality of annularly distributed connecting rods 32 rotatably connected to the outer wall of the fixed sleeve 31, a fixed sleeve 33 fixedly connected to the bottom of the outer wall of the fixed vertical pole 30, a plurality of annularly distributed connecting rods 34 rotatably connected to the outer wall of the fixed sleeve 33, and the end of the connecting rod 32 away from the fixed sleeve 31 is rotatably connected to the middle of the connecting rod 34.

[0025] When the sun umbrella needs to be opened, the sliding sleeve 40 is slid upward along the inner sleeve rod 13, and the connecting rod 1 32 and connecting rod 2 34 in the folding umbrella assembly 3 are unfolded, thereby driving the four inner sleeve rods 13 to unfold. The fixing sleeve 1 31 at the top of the outer wall of the fixed vertical rod 30 provides rotational support for the connecting rod 1 32, and the fixing sleeve 2 33 at the bottom of the outer wall of the fixed vertical rod 30 provides rotational support for the connecting rod 2 34. As the connecting rod 1 32 and connecting rod 2 34 unfold, the umbrella rib structure is formed, supporting the sunshade cloth 15 at the top and realizing the sunshade function. When the sun umbrella needs to be closed, the operation is reversed, causing the sliding sleeve 40 to slide downward along the inner sleeve rod 13, and the connecting rod 1 32 and connecting rod 2 34 to fold, so that the sun umbrella can be folded up when not in use, greatly reducing the volume and making it easy to carry.

[0026] like Figure 5As shown, the limiting and locking assembly 4 includes a sliding sleeve 40. The inner wall of the sliding sleeve 40 is slidably connected to the outer wall of the inner sleeve rod 13. The outer wall of the sliding sleeve 40 is rotatably connected to the end of the connecting rod 2 34 away from the fixed sleeve 2 33. Springs 44 are fixedly connected to both the upper and lower sides of the outer wall of the sliding sleeve 40. A movable plate 42 is fixedly connected to the end of the upper and lower springs 44 away from the sliding sleeve 40. A cylindrical iron block 43 is fixedly connected to the middle of the side of the movable plate 42 near the sliding sleeve 40. Several limiting holes 1 41 are opened on the outer wall of the inner sleeve rod 13 at equal intervals. A limiting hole 2 45 is opened on the outer wall of the sliding sleeve 40, which is adapted to the size of the limiting hole 1 41. The end of the cylindrical iron block 43 away from the movable plate 42 passes through the limiting hole 2 45 and the limiting hole 1 41 respectively and extends into the interior of the inner sleeve rod 13. A vertically arranged electromagnet 46 is fixedly connected inside the inner sleeve rod 13.

[0027] When the sun umbrella is unfolded using the folding umbrella assembly 3, and the position needs to be locked, the electromagnet 46 in the limiting locking assembly 4 is energized. The energized electromagnet 46 generates magnetism, attracting the cylindrical iron block 43 to move towards the electromagnet 46. The spring 44 is compressed. At this time, the cylindrical iron block 43 passes through the limiting hole 1 41 and the limiting hole 2 45 in sequence and extends into the inner sleeve rod 13, thereby limiting the sliding sleeve 40. When the sun umbrella needs to be folded up, the electromagnet 46 is de-energized and loses its magnetism. The springs 44 on the upper and lower sides of the outer wall of the sliding sleeve 40 are reset under the action of elastic force, moving the moving plate 42 and the cylindrical iron block 43 out of the inner sleeve rod 13, thus facilitating the folding and storage of the equipment. At the same time, the cylindrical iron block 43 can be inserted into any of the limiting holes 1 41 set on the outer wall of the inner sleeve rod 13, which facilitates the adjustment of the opening degree of the sun umbrella to adapt to different light angles and ranges.

[0028] It should be noted that the electromagnet 46 is existing technology and will not be described in detail here. Meanwhile, the outer wall of the inner sleeve rod 13 can be provided with a protrusion to restrict the rotation of the sliding sleeve 40, so that the sliding sleeve 40 can only slide up and down on the outer wall of the inner sleeve rod 13 and will not rotate.

[0029] The working principle of this portable sun umbrella will be explained in detail below.

[0030] like Figure 1-5As shown, when it is necessary to fix the sunshade to the medical transport bed, if the medical transport bed is equipped with a hole that matches the insertion rod 11, the insertion rod 11 can be directly inserted into the hole of the medical transport bed. If there is no matching hole, the motor 21 in the fixing assembly 2 is activated. The output end of the motor 21 drives the main gear 23 to rotate. The main gear 23 meshes with the incomplete gear 24, causing the incomplete gear 24 to rotate. The incomplete gear 24 meshes with the incomplete gear 27 below, causing the incomplete gear 27 to rotate. The incomplete gear 24 and the incomplete gear 27... As the fixed rod 25 on the left side of the outer wall of the complete gear 27 rotates, the clamp 26 connected to the end of the two fixed rods 25 away from the incomplete gear 24 moves towards the center under the restriction of the limiting rod 22, clamping the edge of the medical transport cart, thus firmly fixing the sunshade in a specific position, greatly enhancing the stability of the sunshade during use. Even in severe weather conditions such as strong winds, the sunshade can maintain a stable state. At the same time, the fixed component 2 allows the sunshade to be fixed in any place on any type of hospital bed, improving the adaptability of the device.

[0031] When the sun umbrella needs to be opened, the sliding sleeve 40 is slid upward along the inner sleeve rod 13, and the connecting rod 1 32 and connecting rod 2 34 in the folding umbrella assembly 3 are unfolded, thereby driving the four inner sleeve rods 13 to unfold. The fixing sleeve 1 31 at the top of the outer wall of the fixed vertical rod 30 provides rotational support for the connecting rod 1 32, and the fixing sleeve 2 33 at the bottom of the outer wall of the fixed vertical rod 30 provides rotational support for the connecting rod 2 34. As the connecting rod 1 32 and connecting rod 2 34 unfold, the umbrella rib structure is formed, supporting the sunshade cloth 15 at the top and realizing the sunshade function. When the sun umbrella needs to be closed, the operation is reversed, causing the sliding sleeve 40 to slide downward along the inner sleeve rod 13, and the connecting rod 1 32 and connecting rod 2 34 to fold, so that the sun umbrella can be folded up when not in use, greatly reducing the volume and making it easy to carry.

[0032] When the sun umbrella is unfolded using the folding umbrella assembly 3, and the position needs to be locked, the electromagnet 46 in the limiting locking assembly 4 is energized. The energized electromagnet 46 generates magnetism, attracting the cylindrical iron block 43 to move towards the electromagnet 46. The spring 44 is compressed. At this time, the cylindrical iron block 43 passes through the limiting hole 1 41 and the limiting hole 2 45 in sequence and extends into the inner sleeve rod 13, thereby limiting the sliding sleeve 40. When the sun umbrella needs to be folded up, the electromagnet 46 is de-energized and loses its magnetism. The springs 44 on the upper and lower sides of the outer wall of the sliding sleeve 40 are reset under the action of elastic force, moving the moving plate 42 and the cylindrical iron block 43 out of the inner sleeve rod 13, thus facilitating the folding and storage of the equipment. At the same time, the cylindrical iron block 43 can be inserted into any of the limiting holes 1 41 set on the outer wall of the inner sleeve rod 13, which facilitates the adjustment of the opening degree of the sun umbrella to adapt to different light angles and ranges.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
