[0001] This utility model relates to the field of sunshade technology, and more specifically, to a four-corner sunshade. Background Technology

[0002] Sun umbrellas, widely used in outdoor environments such as beaches, poolsides, and courtyards, primarily function to provide users with extensive sun protection. Most mainstream beach umbrellas on the market today employ a traditional round canopy structure with radially supporting ribs. To achieve sufficient sun protection coverage, the canopy diameter is typically designed to be relatively large.

[0003] The length of the ribs of a traditional sun umbrella is usually about the same as the radius of the canopy. When the umbrella is closed, the overall length is not significantly reduced because the ribs cannot be shortened or folded. This results in a large volume of space occupied by the umbrella after it is closed, making transportation and storage more troublesome and greatly limiting users' willingness to carry it and the scenarios in which it can be used.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-7As shown, a four-corner sunshade umbrella includes a central umbrella rod 1, with a lower nest 5 slidably connected to the central umbrella rod 1. A locking block 11 for limiting the lower nest 5 is elastically connected to the upper part of the central umbrella rod 1. Specifically, the locking block 11 is slidably connected to the central umbrella rod 1 via a spring or spring-loaded spring structure, which is existing technology and will not be elaborated here. Therefore, as the lower nest 5 moves upward, it will compress the locking block 11, causing the spring-loaded spring structure to deform under pressure. Once the lower nest 5 passes the locking block 11, the locking block 11 contacts the lower surface of the lower nest 5, achieving the limiting effect. An upper nest 10 is fixedly installed at the top of the central umbrella rod 1, and an umbrella cap 4 is threadedly connected to the upper nest 10. Four umbrella ribs connect the lower nest 5 and the upper nest 10, and an umbrella canopy is installed on all four ribs, with the center of the umbrella canopy located between the upper nest 10 and the umbrella cap 4. The umbrella canopy has four corners with fixed plug-in blocks 9. Each plug-in block 9 has a first slot and a locking groove 91 connected to the first slot. Each rib includes a main section 6, a secondary section 7 and a linkage section 8. One end of the main section 6 is rotatably connected to the upper nest 10. The other end of the main section 6 is fixedly connected to a mounting base 61 with a mounting groove 611. The two ends of the linkage section 8 are rotatably connected to the main section 6 and the lower nest 5, respectively. One end of the secondary section 7 is rotatably connected to the mounting groove 611. The other end of the secondary section 7 is slidably connected to a locking pin 71. A first spring is installed between the locking pin 71 and the secondary section 7 to push the locking pin 71 outward. When the end of the secondary section 7 is fully inserted into the first slot, the locking pin 71 is engaged in the locking groove 91 to achieve the connection between the secondary section 7 and the plug-in block 9.

[0026] It is understandable that a stud is fixedly connected to the umbrella cap 4, and a screw hole is provided at the center of the top surface of the upper nest 10. The stud passes through the center of the umbrella surface and is threadedly connected to the screw hole to achieve the fixation between the upper nest 10 and the umbrella cap 4.

[0027] It is worth mentioning that the umbrella ribs adopt a hinged design of main section 6, secondary section 7 and linkage section 8. When closing the umbrella, as the linkage section 8 drives the main section 6 to close, the secondary section 7 will also fold upward. In addition, the umbrella rod 1 is divided into upper rod 101 and lower rod 102, and the lower rod 102 can be disassembled, which greatly shortens the overall storage length and significantly reduces the volume, making it convenient for transportation and storage.

[0028] It is worth mentioning that a cloth pad is sewn on each of the four corners of the umbrella canopy, and the insert block 9 is fixedly connected to the cloth pad. The cloth pad can increase the strength of the umbrella canopy at that position and prevent tearing.

[0029] Understandably, the umbrella canopy is connected to the umbrella ribs via plug-in blocks 9 at the four corners and locked by locking pins 71 driven by the first spring. Assembly can be completed simply by inserting the plugs, and the locking is secure and easy to install and remove.

[0030] As a preferred option, such as Figure 2 , Figure 3 and Figure 7As shown, a positioning seat 62 that rotates with the linkage 8 is fixedly connected to the middle of the main section 6. A protrusion 621 is slidably connected to the side of the positioning seat 62 facing the linkage 8. A second spring 622 for pushing the protrusion 621 to move outward is installed between the protrusion 621 and the positioning seat 62.

[0031] It is understandable that when the umbrella ribs are closed, the linkage 8 will first hit the protrusion 621 and compress the second spring 622, which can achieve a certain buffering effect, avoid direct collision between the linkage 8 and the main section 6, reduce the risk of damage at the connection between the two, improve the service life of the umbrella, and make it convenient to open and close the umbrella.

[0032] As a preferred option, such as Figure 1 As shown, each of the four corners of the umbrella is fixedly connected with a hanging cloth 33, and the lower end of the hanging cloth 33 is fixedly connected with a storage bag 34 for placing sand.

[0033] Understandably, the storage bag 34 can be filled with sand or stones to increase its weight, and the weight is distributed around the perimeter by the tensioning effect of the four vertical fabric pillars 33, which greatly enhances the umbrella's wind resistance stability on soft surfaces such as sand.

[0034] As a preferred option, such as Figure 1 As shown, a mesh bag 331 is provided on the upper inner side of the vertical cloth 33.

[0035] Understandably, the mesh bag 331 can be used to store small items, such as mobile phones and keys, and when not in use, the storage bag 34 and the hanging cloth 33 can be rolled up from bottom to top and stuffed into the mesh bag 331, making it neater when folded up.

[0036] As a preferred option, such as Figure 5 As shown, a cloth cover 321 is fixedly connected to the inner side of the umbrella canopy for the passage of the sub-section 7 and for limiting the position of the sub-section 7.

[0037] Understandably, during assembly, the sub-section 7 needs to pass through the cloth sleeve 321 before it can connect with the plug block 9. The cross-sectional area of ​​the cloth sleeve 321 is slightly larger than that of the sub-section 7, so it can guide and constrain the sub-section 7, ensuring that the sub-section 7 can move along the predetermined path during the unfolding process, thereby improving the smoothness of unfolding and the neatness of the structure.

[0038] As a preferred option, such as Figure 1 As shown, the umbrella canopy includes a first umbrella canopy 31 located at the center and a second umbrella canopy 32 arranged around the first umbrella canopy 31. The outer edge of the first umbrella canopy 31 overlaps with the inner edge of the second umbrella canopy 32, and a number of ventilation gaps are formed between the first umbrella canopy 31 and the second umbrella canopy 32.

[0039] It is understandable that by designing the umbrella canopy in two parts, since most of the overlapping areas of the first umbrella canopy 31 and the second umbrella canopy 32 are not sewn together, ventilation gaps are formed. Furthermore, because the umbrella canopy has a certain angle, it can effectively guide wind force, reduce wind resistance, improve wind resistance, and further enhance the stability of the umbrella during use.

[0040] As a preferred option, such as Figure 2 and Figure 6 As shown, the umbrella rod 1 is divided into an upper rod 101 and a lower rod 102. The lower end of the upper rod 101 is provided with a second slot. The upper part of the lower rod 102 is inserted into the second slot to realize the connection between the upper rod 101 and the lower rod 102. The lower end of the lower rod 102 is provided with a third slot 1021. A plug 2 for inserting into the sand is inserted into the third slot 1021.

[0041] It is understandable that, such as Figure 6 As shown, each of the upper rod 101 and the lower rod 102 has a ring 103 fixed on its outer side. When the lower rod 102 is inserted along the second slot at its upper part, the insertion between the upper rod 101 and the lower rod 102 is completed when the two rings 103 abut against each other.

[0042] It is worth mentioning that a plastic gasket is fixedly connected to the inner bottom surface of the third slot 1021, and a plastic sleeve is fixedly connected to the upper end of the insertion rod 2. By using external force to drive the lower rod 102 to strike the insertion rod 2, the insertion rod 2 can be smoothly and firmly inserted into the sand or soil. On this basis, due to the mutual impact and cooperation between the plastic gasket and the plastic sleeve, it is both labor-saving and can improve the service life.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
