[0039] The utility model provides a double-layer umbrella stand and a double-layer umbrella, such as Figure 1-Figure 4 As shown, a double-layer umbrella stand includes an umbrella pole 1, main ribs 2 and supporting ribs 3. The umbrella pole 1 is provided with an upper honeycomb 11 and a lower honeycomb 12 at intervals. The main ribs 2 include multiple groups of first main ribs 21 and second main ribs 22 that are rotatably connected to each other. One end of the first main rib 21 is connected to the upper honeycomb 11 at intervals along the circumference of the umbrella pole 1, and the end of the second main rib 22 facing away from the first main rib 21 is connected to the lower honeycomb 12 at intervals along the circumference of the umbrella pole 1. The main ribs 2 are used to mount an outer umbrella cloth 4. The structure in which the umbrella pole 1 is connected to the first and second main ribs 21 and 22 of the main ribs 2 via the upper honeycomb 11 and the lower honeycomb 12 is a conventional structure and can be specifically configured as a one-fold umbrella stand, a two-fold umbrella stand, a three-fold umbrella stand, etc. In the embodiment of the present invention, on the basis of the umbrella frame structure, supporting ribs 3 are additionally provided. The supporting ribs 3 include a plurality of groups of first ribs 31 and second ribs 32 rotatably connected to each other. The end of the first rib 31 away from the second rib 32 is connected to the upper honeycomb 11, and the end of the second rib 32 away from the first rib 31 is connected to the lower honeycomb 12. The supporting ribs 3 are used to install the inner umbrella cloth 5.

[0040] When the umbrella is opened, the umbrella 2 is opened, and the inner layer of the umbrella 2 is opened, and the inner layer of the umbrella 2 is opened, and the outer layer of the umbrella 2 is opened, and the inner layer of the umbrella 2 is opened, and the inner layer of the umbrella 2 is opened, and the inner layer of the umbrella 2 is opened. It can be seen that the utility model achieves the effects of double-layer heat insulation and neat storage at the same time.

[0041] Optionally, multiple first main bones 21 and multiple first branch bones 31 are alternately arranged on the upper honeycomb 11 around the umbrella pole 1 circumferentially, and multiple second main bones 22 and multiple second branch bones 32 are alternately arranged on the lower honeycomb 12 around the umbrella pole 1 circumferentially.

[0042] It will be appreciated that when the number of first main ribs 21 and first branch ribs 31 is the same, the first main ribs 21 and first branch ribs 31 are alternately arranged to uniformly secure and support the outer and inner fabric layers 4 and 5. When the number of first main ribs 21 is greater than the number of first branch ribs 31, more than two first main ribs 21 may be arranged between two adjacent first branch ribs 31, for a circumferentially alternating arrangement. This arrangement is simple and easy to implement, and facilitates uniform spacing of the first branch ribs 31. Of course, in other embodiments, the number of first main ribs 21 between two adjacent first main ribs 31 may be the same or different, alternating arrangement, and not necessarily uniform. For example, multiple first main ribs 21 and multiple first branch ribs 31 may be distributed in their respective arc regions rather than uniformly distributed circumferentially. The arrangement of the second main ribs 22 and second branch ribs 32 on the lower honeycomb 12 is similar to that of the upper honeycomb 11 and will not be further described.

[0043] Optionally, in the unfolded state, an angle A is formed between the first branch bone 31 and the umbrella pole 1 , an angle B is formed between the first main bone 21 and the umbrella pole 1 , and the angle A is smaller than the angle B.

[0044] like Figure 2As shown, any one of the first main ribs 21 forms an angle B with the umbrella shaft 1. Angle B represents the angle at which the outer fabric 4 is deployed relative to the umbrella shaft 1. Any one of the first branch ribs 31 forms an angle A with the umbrella shaft 1, which is smaller than angle B. Therefore, the supporting ribs 3 are located inside the main ribs 2 for mounting the inner fabric 5. With angle B fixed, the smaller the angle A, the larger the gap between the outer fabric 4 and the inner fabric 5, and the better the insulation. Because the supporting ribs 3 are used to mount the inner fabric 5, they can pull the inner fabric 5 up when retracted. Working in conjunction with the lower honeycomb 12 connected to the middle portion of the inner fabric 5 and the main ribs 2 connected to the outer edges of the inner fabric 5, the inner fabric 5 is stretched by the main ribs 2, the supporting ribs 3, and the lower honeycomb 12 during retraction, facilitating the neat stowage of the inner fabric 5 and facilitating storage. When deployed, the supporting ribs 3 support the inner fabric 5. The outer edge of the inner umbrella cloth 5 is connected to the multiple first main ribs 21 along the circumferential direction, and the center of the inner umbrella cloth 5 is connected to the lower honeycomb 12. The inner umbrella cloth 5 is jointly supported or retracted by the supporting ribs 3 and the main ribs 2, so that the inner umbrella cloth 5 can be unfolded flat or folded neatly.

[0045] Optionally, the rotational connection is a movable riveting connection.

[0046] It can be understood that the rotational connection between the first main rib 21 and the second main rib 22, as well as the rotational connection between the first branch rib 31 and the second branch rib 32, can adopt a movable riveting connection method. The movable riveting has the advantages of simple structure and small installation space, and can provide higher connection strength, which is beneficial to improving the service life of the main umbrella rib 2 and the branch umbrella rib 3.

[0047] Optionally, a connecting portion 321 is provided on the first support 31 or the second support 32 , and the inner umbrella cloth 5 is connected to the connecting portion 321 .

[0048] It will be appreciated that the first and second ribs 31 and 32 are pivotally connected relative to the distal end of the umbrella pole 1. The second rib 32 can be pivotally connected to the first rib 31 at any position along its length to provide various support configurations for the inner umbrella cloth 5. The provision of the connecting portion 321 facilitates installation of the inner umbrella cloth 5, and the position of the connecting portion 321 can be adjusted based on the size of the inner umbrella cloth 5 to facilitate folding and stowing of the inner umbrella cloth 5.

[0049] In this embodiment, the connecting portion is disposed on the first main bone 32 , and the connecting portion 321 extends from the first main bone 32 toward a direction away from the second branch bone 32 .

[0050] like Figure 3 and Figure 4As shown, during the process of rotational folding and unfolding, the inner layer of the umbrella cloth 5 may become stuck and affect rotation due to the proximity of the connection between the inner layer of the umbrella cloth 5 and the first or second ribs 31, 32. In this embodiment, a connecting portion 321 is provided on the second rib 32, and the connecting portion 321 is arranged in a direction away from the second rib 32 and the first rib 31. That is, the connecting portion 321 is provided on the lower surface of the second rib 32. This allows the connection position of the inner layer of the umbrella cloth 5 to be away from the connection between the first and second ribs 31, 32, thereby preventing positional interference that may affect the normal operation of the double-layer umbrella frame.

[0051] Optionally, the connecting portion 321 and the second rib 32 are arranged perpendicular to each other.

[0052] like Figure 4 In the unfolded state, the connecting portion 321 is vertically downward and parallel to the umbrella pole 1. The end of the connecting portion 321 is connected to the inner umbrella cloth 5. When folded, the connecting portion 321 can stretch the middle position of the inner umbrella cloth 5, and cooperate with the lower honeycomb 12 and the main umbrella ribs 2 to achieve controllable folding and folding of the inner umbrella cloth 5.

[0053] By adjusting the length of the connecting portion 321 and the angle A, the gap between the outer and inner layers of the umbrella fabric 4, 5 can be adjusted to meet the thermal insulation requirements for use in different regions. In this embodiment, the first and second supports 31, 32 are each a rectangular flat bar structure with mounting surfaces at each end to facilitate rotational connection. This rectangular flat bar structure helps ensure the stability of the rotational plane of the inner layer of the umbrella fabric 5, preventing circumferential rotation. The connecting portion 321 extends away from the first and second supports 31, 32, thereby facilitating connection of the inner layer of the umbrella fabric 5 away from the junction of the first and second supports 31, 32, protecting the inner layer of the umbrella fabric 5 and preventing positional interference.

[0054] Optionally, the first support bone 31 is provided with a first hole 311 , and the first support bone 31 is connected to the upper honeycomb 11 through the first hole 311 via a first connecting member.

[0055] Optionally, the second support bone 32 is provided with a second hole 322 , and the second connecting member passes through the second hole 322 and is connected to the lower honeycomb 12 .

[0056] Optionally, the connecting portion 321 is provided with a third hole 323 , and the third connecting member passes through the third hole 323 and is connected to the inner umbrella cloth 5 .

[0057] like Figure 5 As shown, combined Figure 2The first, second, and third connectors are all flexible connectors, facilitating the connection between the two interconnected components and allowing for free movement. For double-layer umbrella stands, from a weight-saving perspective, the first, second, and third connectors are preferably constructed using binding wire, which is low-cost, lightweight, and readily available. After binding, the two interconnected components maintain a relatively fixed position and are able to rotate freely. This is suitable for conventional outer and inner layers of umbrella fabric 4, 5, and allows for connection without requiring additional design or processing. Preferably, the binding wire can be metal wire or sewing thread. Furthermore, the outer and inner layers of umbrella fabric 4, 5 are both secured and connected by sewing thread, the upper and lower honeycombs 11, 12 are both secured and connected by metal wire threading, and the pivoting connections on the main and support ribs 2, 3 are riveted.

[0058] like Figure 4 As shown, when deployed, the second rib 32 is perpendicular to the shaft 1, while the connecting portion 321 is parallel to the shaft 1. This maximizes the surface area of the inner fabric 5, creating a conical insulating space between the inner and outer fabrics 5 and 4, resulting in excellent insulation. When folded, the lower honeycomb 12 descends, driving the main ribs 2 and the support ribs 3 to rotate and fold. The center of the inner fabric 5 slides and pulls downward along the shaft 1 along with the lower honeycomb 12. The first main rib 21 rotates and folds the outer and inner fabrics 4 downward toward the shaft 1, and the second rib 32 rotates and folds the center of the inner fabric 5 toward the upper honeycomb 11, ensuring a neat folding of the inner and outer fabrics 5 and 4.

[0059] The double-layer umbrella provided by the utility model is as follows Figure 1 and Figure 6 As shown, the double-layer umbrella frame provided by the present invention includes an outer umbrella cloth 4 and an inner umbrella cloth 5, and the outer umbrella cloth 4 is arranged on the outer side of the main umbrella rib 2 of the double-layer umbrella frame, and the inner umbrella cloth 5 is connected to the supporting umbrella rib 3 of the double-layer umbrella frame, so that there can be a sufficient gap between the outer umbrella cloth 4 and the inner umbrella cloth 5 in the open umbrella state, and the umbrella can be folded more neatly under the drive of the supporting umbrella rib 3 in the folded umbrella state; by arranging the main umbrella rib 2 and the supporting umbrella rib 3 separately, the gap between the outer umbrella cloth 4 and the inner umbrella cloth 5 can be controlled, thereby obtaining a double-layer umbrella with the required heat insulation effect, which is more flexible in arrangement and has a wide range of applications.

[0060] Optionally, the center of the inner umbrella cloth 5 is connected to the lower honeycomb 12, the middle position of the inner umbrella cloth 5 in the radial direction is connected to the connecting portion 321 of the second branch rib 32 of the supporting rib 3, and the outer edge of the inner umbrella cloth 5 is connected to the multiple first main ribs 21 of the main umbrella rib 2.

[0061] As can be understood, the inner layer of the umbrella fabric 5 can be neatly folded and unfolded under the combined action of the main ribs 2 and the supporting ribs 3. This structure is simple, the overall volume remains unchanged, and the internal space of the outer layer of the umbrella fabric 4 is fully utilized. The second supporting ribs 32 and the second main ribs 22 are arranged in a staggered manner. The inner layer of the umbrella fabric 5 is connected to the second supporting rib 32 at a position intermediate between any radial center and the outer edge, while the outer edge is connected to the first main rib 21. Therefore, an exhaust hole is formed at the junction of the outer and inner layers of the umbrella fabric 4, 5, facilitating the dissipation of hot air between the outer and inner layers of the umbrella fabric 4, 5.

[0062] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
