Description

Technical Field

[0001] This utility model belongs to the field of sunshade umbrella technology, specifically relating to a novel flat sunshade umbrella. Background Technology

[0002] As people's living standards improve, the demand for sun umbrellas is also increasing. Flat sun umbrellas are favored because they take up little space and the canopy is less likely to come into contact with the user. In existing flat umbrellas, the canopy is usually kept taut, which can lead to premature aging of the canopy after a period of use, affecting the normal use of the flat umbrella and its appearance. In addition, whether the flat umbrella has a rotating canopy function also directly affects the user's comfort and experience. Utility Model Content

[0003] To address the aforementioned issues, this utility model aims to provide a novel flat sunshade umbrella that can adjust the tension of the umbrella fabric, significantly extending its service life. It also allows for adjustment of the umbrella's tilt angle. Various types of components are available for users to choose from to control the fabric tension and tilt angle, meeting diverse user needs. Furthermore, the overall operation is simple and convenient.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A novel flat sunshade umbrella includes a support rod, two crossbars, an umbrella support part, and an umbrella cloth. The two ends of the umbrella cloth are sleeved on the crossbars. The two ends of the support rod are connected to the crossbars through the umbrella support part. It also includes a tensioning mechanism, which is set at the end of the support rod and matched with the umbrella support part. Adjusting the tensioning mechanism can control the sliding of the umbrella support part relative to the support rod, so that the umbrella cloth is taut or untapped.

[0005] It also includes an angle adjustment mechanism, a fastening part, and an upright. One end of the fastening part is connected to the support rod, and the other end is connected to the angle adjustment mechanism. The other end of the angle adjustment mechanism is connected to the upper end of the upright, so that the support rod and the upright can be fixed at a set angle.

[0006] The angle adjustment mechanism includes a first knob, a rotating part, a rotating housing, a first locking part, and a second locking part. The rotating part includes a rotating ball part and a rotating shaft part. The rotating ball part, the first locking part, the second locking part, and the upper end of the upright are arranged sequentially from top to bottom inside the rotating housing. The lower surface of the first locking part and the upper surface of the second locking part are mutually cooperating inclined surfaces. The first locking part and the second locking part can slide relative to each other. When the lower surface of the first locking part and the upper surface of the second locking part are engaged at different positions on the inclined surfaces, the top height of the first locking part is different, which drives the rotating ball part to move up and down.

[0007] The shaft of the first knob passes through and connects to the second locking part, allowing the second locking part to move horizontally within the rotating housing. When the first knob is rotated to move the second locking part outward, the total height of the first and second locking parts decreases, causing the first locking part to move downward, thereby loosening the rotating ball part from the rotating housing and allowing the angle adjustment mechanism to rotate freely. When the first knob is rotated to move the second locking part inward, a tight fit is formed between the first and second locking parts, fixing the angle adjustment mechanism.

[0008] A sliding groove is provided at one end of the support rod that connects to the umbrella support part, and a connecting hole is provided on the umbrella support part. The tensioning mechanism passes through the sliding groove and the connecting hole. The tensioning mechanism controls the tension or relaxation of the umbrella fabric by moving in the sliding groove and driving the umbrella support part to move in coordination.

[0009] The tensioning mechanism includes a ring, a connecting rod, a handle, and a connecting shaft. The ring is located on the upper part of the support rod. The two ends of the connecting rod are connected to the ring and the middle of the handle, respectively. The connecting shaft passes through and connects the end of the handle, the sliding groove, and the connecting hole. Adjusting the other end of the handle can control the tension or relaxation of the umbrella fabric.

[0010] The tensioning mechanism includes a fixed base, a first connecting rod, a second connecting rod, a handle, a hinge rod, and a connecting shaft. A groove is formed at the bottom of the support rod. The first and second connecting rods are located inside the fixed base and pass through the groove. Several adjustment slots are provided below the fixed base. The handle is located in any one of the adjustment slots. One end of the handle is hinged to the hinge rod, and the other end of the hinge rod is hinged to both the first and second connecting rods. The other end of the first connecting rod is hinged to the support rod. The connecting shaft passes through and connects the other end of the second connecting rod, a sliding groove, and a connecting hole. Adjusting the handle to different adjustment slots controls the tension or relaxation of the umbrella fabric.

[0011] The fastening part includes a clamping part and a second knob. The upper end of the clamping part clamps the support rod, and the lower end of the clamping part is fastened to the rotating shaft. The second knob passes through and connects to the clamping part. Rotating the second knob can control the fastening part, so that the fastening part and the support rod are either loose or tight.

[0012] The fastening part includes a three-way clamping part and at least one second knob. The three-way clamping part includes a main clamping part and a support clamping part. The main clamping part clamps the support rod, and the support clamping part is fastened to the rotating shaft part. The second knob passes through and connects to the lower parts of both ends of the main clamping part.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Combined with appendix Figures 1 to 9 As shown, this embodiment discloses a novel flat sunshade umbrella, including a vertical pole 1, a support pole 2, two horizontal poles 3, an umbrella fabric 4, an angle adjustment mechanism 5, a fastening part 6, and a tensioning mechanism 7. The umbrella fabric 4 is fitted onto the horizontal poles 3 at both ends. The support pole 2 is connected to the horizontal poles 3 at both ends through an umbrella-supporting part 21. The tensioning mechanism 7 is located at the end of the support pole 2 and is matched and connected to the umbrella-supporting part 21. Adjusting the tensioning mechanism 7 can control the sliding of the umbrella-supporting part 21 relative to the support pole 2, so that the umbrella fabric 4 is taut or untapped. One end of the fastening part 6 is connected to the support pole 2, and the other end is connected to the angle adjustment mechanism 5. The other end of the angle adjustment mechanism 5 is connected to the upper end of the vertical pole 1, so that the support pole 2 can be fixed to the vertical pole 1 at a set angle.

[0028] In summary, the angle adjustment mechanism 5 includes a first knob 51, a rotating part 52, a rotating housing 53, a first locking part 54, and a second locking part 55. The rotating part 52 includes a rotating ball part 521 and a rotating shaft part 522. The rotating ball part 521, the first locking part 54, the second locking part 55, and the upper end of the upright 1 are arranged sequentially from top to bottom inside the rotating housing 53. The lower surface of the first locking part 54 and the upper surface of the second locking part 55 are mutually cooperating inclined surfaces. The first locking part 54 and the second locking part 55 can slide relative to each other. When the lower surface of the first locking part 54 and the upper surface of the second locking part 55 are engaged at different positions on the inclined surfaces, the top height of the first locking part 54 is different, which drives the rotating ball part 521 to move up and down.

[0029] With the above-described installation structure, the shaft of the first knob 51 is connected to the second locking part 55. When the first knob 51 is rotated, the second locking part 55 can move horizontally within the rotating housing 53. When the first knob 51 is rotated to move the second locking part 55 outward, the rear part of the second locking part 55 gradually changes from supporting the rear part of the first locking part 54 to supporting the middle part of the first locking part 54. Since the contact surfaces of the first locking part 54 and the second locking part 55 are inclined, the total height between the first locking part 54 and the second locking part 55 decreases, causing the first locking part 54 to move downward. This causes the total height between the rotating ball part 521 and the first locking part 54 to also decrease, that is, the first locking part 54 and the rotating housing 53 become loose, and the rotating ball part 521 can rotate freely within the rotating housing 53. This state is the unlocked state of the angle adjustment mechanism 5. Conversely, after the angle adjustment mechanism 5 has determined the rotation angle, when the first knob 51 is rotated to move the second locking part 55 inward, the first locking part 54 and the second locking part 55 become tight, fixing the angle adjustment mechanism 5. This state is the locked state of the angle adjustment mechanism 5.

[0030] With the above installation structure, users can freely adjust the tilt angle of the umbrella canopy by adjusting the first knob 51. The operation is simple and convenient, and the umbrella canopy with different tilt angles can be used in more scenarios, improving the practicality of this flat umbrella.

[0031] In combination with the above, a sliding groove 22 is provided at one end of the support rod 2 that is connected to the umbrella support part 21, and a connecting hole 211 is provided on the umbrella support part 21. The tensioning mechanism 7 passes through and connects the sliding groove 22 and the connecting hole 211. The tensioning mechanism 7 controls the tensioning or untensioning of the umbrella cloth 4 by moving in the sliding groove 22 and driving the umbrella support part 21 to move in coordination.

[0032] In summary, the tensioning mechanism 7 includes various mounting structures, and several preferred embodiments of the tensioning mechanism 7 are listed below. Example

[0033] Combination Figure 5 As shown, the tensioning mechanism 7 includes a ring 71, a connecting rod 72, a handle 73, and a connecting shaft 74. The ring 71 is located on the upper part of the support rod 2. The two ends of the connecting rod 72 are respectively connected to the ring 71 and the middle of the handle 73. The connecting shaft 74 passes through and connects the end of the handle 73, the sliding groove 22, and the connecting hole 211. Adjusting the other end of the handle 73 changes the position of the end connected to the connecting shaft 74, causing the connecting shaft 74 to move within the sliding groove 22. The connecting shaft 74 causes the umbrella support 21 to move, thereby controlling the tension or relaxation of the umbrella fabric 4. After the tension of the umbrella fabric 4 is determined, the connecting rod 72 will contact the ring 71 and the handle 73, thus fixing the handle 73. Example

[0034] Combination Figure 6 and Figure 7 As shown, the tensioning mechanism 7 includes a fixed base 75, a first connecting rod 721, a second connecting rod 722, a handle 76, a hinge rod 761, and a connecting shaft 74. A groove is formed at the lower part of the end of the support rod 2 that connects to the umbrella-supporting part 21. The first connecting rod 721 and the second connecting rod 722 are disposed inside the fixed base 75 and pass through the groove. Several adjustment slots 751 are provided below the fixed base 75. The handle 76 is disposed in any one of the adjustment slots 751. The handle 76 is hinged to one end of the hinge rod 761. The other end of the hinge rod 761 is hinged to the first connecting rod 721 and the second connecting rod 722. The other end of the first connecting rod 721 is hinged to the support rod 2. The connecting shaft 74 passes through the other end of the second connecting rod 722, the sliding groove 22, and the connecting hole 211. The adjusting handle 76 is moved to different adjusting grooves 751, so that the hinge rod 761 can drive the first connecting rod 721 and the second connecting rod 722 to move in coordination. The other end of the second connecting rod 722 drives the connecting shaft 74 to move in coordination within the sliding groove 22. The connecting shaft 74 drives the umbrella-supporting part 21 to move, thereby controlling the tension or relaxation of the umbrella fabric 4. After the tension of the umbrella fabric 4 is determined, the first connecting rod 721, the second connecting rod 722, the hinge rod 761, and the support rod 2 will contact and rub against each other, thus fixing the second connecting rod 722.

[0035] Combined with the above installation structure, the tension of the umbrella fabric 4 can be controlled by adjusting the tensioning mechanism 7. The overall adjustment process is simple and convenient. When not in use, the umbrella fabric 4 can be in a relaxed state, which can extend the service life of the umbrella fabric 4 and prevent the umbrella fabric 4 from becoming functionally damaged and aesthetically diminished before reaching the expected service life.

[0036] In conjunction with the above, the fastening part 6 includes various mounting structures, and several preferred embodiments of the fastening part 6 are listed below. Example

[0037] Combination Figure 8 As shown, the fastening part 6 includes a clamping part 61 and a second knob 62. The upper end of the clamping part 61 clamps the support rod 2, and the lower end of the clamping part 61 is fastened to the rotating shaft part 522. The shaft part of the second knob 62 passes through and connects to the clamping part 61. Rotating the second knob 62 can control the fastening part 6, so that the fastening part 6 and the support rod 2 are either loose or tight. Example

[0038] Combination Figure 9As shown, the fastening part 6 includes a three-way clamping part 63 and at least one second knob 62. The three-way clamping part 63 includes a main clamping part 631 and a support clamping part 632. The support clamping part 632 is located in the middle of the main clamping part 631 and forms a 90-degree angle with the main clamping part 631. The main clamping part 631 clamps the support rod 2. The support clamping part 632 is fastened to the rotating shaft part 522. The shaft part of the second knob 62 passes through and connects to the lower parts of both ends of the main clamping part 631. Rotating the second knob 62 can control the fastening part 6, so that the fastening part 6 and the support rod 2 are either loose or tight.

[0039] The above installation structure allows for a secure connection between the angle adjustment mechanism 5 and the support rod 2, improving the structural strength of the flat umbrella and preventing the umbrella canopy from detaching from the upright rod 1 due to strong winds or other environmental factors, thus affecting the normal use of the flat umbrella.

[0040] In conjunction with the above, the flat umbrella also includes a sleeve 8, which extends the height of the umbrella pole to suit different usage scenarios. The sleeve 8 is located below the upright pole 1. The sleeve 8 and the upright pole 1 are connected to each other by a third knob 81 and a connecting sleeve 82. The shaft of the third knob 81 passes through and connects the lower end of the upright pole 1, the connecting sleeve 82 and the upper end of the sleeve 8. Rotating the third knob 81 can adjust the tightness between the upright pole 1 and the sleeve 8.

[0041] This invention can adjust the tension of the umbrella fabric, which can greatly extend the service life of the umbrella fabric. At the same time, it can adjust the tilt of the umbrella surface. There are various types of components for controlling the tension and tilt angle of the umbrella fabric, which can meet the various needs of users. The overall operation is simple and convenient.

[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
