[0034] See also Figures 1 to 7 , the present invention provides a technical solution:

[0035] Example 1

[0036] A foldable indicating device comprises: a supporting assembly 1, a base 6, a dustproof cloth cover 7 and a cover 8.

[0037] Specifically, the support assembly 1 includes a spring element 2 and an anti-dumping column 3. The spring element 2 is spiral-shaped. The anti-dumping column 3 is arranged on the inner side of the spring element 2. The outer wall of the anti-dumping column 3 is fixedly connected with a connecting collar 4. The connecting collar 4 is movably sleeved on the outer side of the spring element 2. The spring element 2 can be pulled upward to change the height of the entire support assembly 1. The spring element 2 can also be rotated counterclockwise (such as Figure 3The upper end of the support assembly 1 is adjusted to change the diameter of the support assembly 1, thereby adjusting the size of the space inside the support assembly 1. The anti-dumping column 3 is provided to prevent the spring element 2 from tilting and deforming to the side, thereby preventing the support assembly 1 from tipping over when placed;

[0038] Secondly, the base 6 is arranged at the lower end of the support assembly 1, and the lower end of the spring element 2 and the lower end of the anti-dumping column 3 are both slidably connected to the base 6 along the radial direction of the base 6, so that the anti-dumping column 3 can slide along the radial direction of the base 6, thereby avoiding obstruction to the deformation of the support assembly 1, and the base 6 is placed on the ground to maintain a fixed position. When the upper end of the spring element 2 rotates counterclockwise, the diameter of the support assembly 1 itself becomes larger, and the anti-dumping column 3 can slide radially outward along the base 6 under the connection action of the connecting ring 4; and when the upper end of the spring element 2 is pulled upward, the anti-dumping column 3 can be extended accordingly, thereby increasing the overall height of the support assembly 1. Therefore, the internal space of the support assembly 1 of this device can be adjusted according to actual needs. After the emergency items are placed inside the support assembly 1, the upper end of the spring element 2 is released, and the spring element 2 can automatically shrink and reset under the action of its own elastic force, and drive the anti-dumping column 3 to shrink, thereby minimizing the overall volume of the support assembly 1 and reducing the space occupied by the support assembly 1 when placed;

[0039] Furthermore, a dustproof cloth cover 7 is wrapped around the outside of the support assembly 1 and bonded to the spring element 2 to protect the items inside the support assembly 1 from dust;

[0040] In addition, the cover 8 is provided at the upper end of the support assembly 1 , and the cover 8 covers the outer side of the upper end opening of the dustproof cloth cover 7 from top to bottom, and is used to prevent dust from the open end of the dustproof cloth cover 7 .

[0041] Example 2

[0042] On the basis of Example 1, in order to improve the elastic deformation capacity of the support assembly 1, the present application provides at least two spring elements 2 to improve the elastic deformation capacity of the support assembly 1, and multiple anti-dumping columns 3 are provided and distributed in a circular array to ensure stable support for the support assembly 1. The anti-dumping columns 3 are multi-section telescopic rods.

[0043] Example 3

[0044] On the basis of Example 2, in order to prevent the anti-dumping column 3 from tilting, the present application also has an "I"-shaped slider 5 fixedly connected to the lower end of the spring element 2 and the lower end of the anti-dumping column 3, and a plurality of limiting grooves 16 are radially opened on the surface of the base 6. The plurality of limiting grooves 16 respectively correspond to the plurality of spring elements 2 and the plurality of anti-dumping columns 3. The "I"-shaped slider 5 is located in the inner cavity of the limiting groove 16 and is slidably connected thereto. The "I"-shaped slider 5 can only slide along the length direction of the limiting groove 16, and the "I"-shaped slider 5 itself cannot tilt, thereby ensuring that the anti-dumping column 3 can only slide along the length direction of the limiting groove 16 and cannot tilt.

[0045] Example 4

[0046] On the basis of embodiment three, in order to facilitate pulling or rotating the upper end of the support assembly 1, the present application also has a deformable ring 9 provided at the upper end of the support assembly 1, the two ends of the deformable ring 9 cross and overlap each other, and both ends of the deformable ring 9 are fixedly connected to a guide ring 10, which is movably sleeved on the outer side of the middle part of the deformable ring 9. The structure of the deformable ring 9 and the guide ring 10 is as follows: Figure 5 As shown, the diameter of the circle surrounded by the deforming ring 9 can be adjusted, and the upper end of the spring element 2 is fixedly connected to the deforming ring 9. Since the diameter of the end of the support assembly 1 will change when it is deformed, and the diameter of the circle surrounded by the deforming ring 9 can also be adjusted, the two can adapt to each other. After the deforming ring 9 is fixedly connected to the upper end of the spring element 2, the upper end of the support assembly 1 can be driven to move or rotate by pulling the deforming ring 9 or rotating the deforming ring 9.

[0047] Example 5

[0048] On the basis of Example 4, in order to position the edge of the dustproof cloth cover 7, the upper edge of the dustproof cloth cover 7 of the present application is folded inward to form an annular cloth cover 11, and the annular cloth cover 11 is arranged on the outside of the deformation ring 9. On the one hand, it protects the surface of the deformation ring 9, and on the other hand, it can position the edge of the dustproof cloth cover 7. The two sides of the surface of the deformation ring 9 are fixedly connected with a hanging plate 12 and a handle 13 respectively. The hanging plate 12 and the handle 13 both pass through the annular cloth cover 11 and extend to its outside. The setting of the handle 13 facilitates manual movement or rotation of the deformation ring 9.

[0049] Example 6

[0050] On the basis of Example 5, in order to further prevent dust from entering the items inside the support assembly 1, the sealing cover 8 of the present application includes a circular sealing cloth 14, and an elastic rope 15 is fixedly connected to the edge of the sealing cloth 14. The sealing cloth 14 is fixedly connected to the handle 13, and the elastic rope 15 is sleeved on the outer side of the upper end of the support assembly 1 and buckled on the inner side of the hanging plate 12. Both the sealing cloth 14 and the elastic rope 15 can be elastically deformed. After the sealing cloth 14 is sleeved on the outer side of the upper end of the dustproof cloth cover 7, the elastic rope 15 can cover the upper end opening of the dustproof cloth cover 7, thereby preventing dust from entering the dustproof cloth cover 7 and the interior of the support assembly 1.

[0051] Example 7

[0052] On the basis of Example 6, in order to prevent emergency items placed on the upper surface of the base 6 from pressing on the surface of the "I"-shaped slider 5 and affecting the sliding of the "I"-shaped slider 5, the present application also has a boss 17 fixedly connected to the upper surface of the base 6, and the surface of the boss 17 is provided with an avoidance groove 18 corresponding to a plurality of limiting sliding grooves 16, which is used to avoid the "I"-shaped slider 5 from colliding with the boss 17 when sliding. The upper surface of the boss 17 is flush with the upper surface of the "I"-shaped slider 5, which can prevent items placed on the upper surface of the base 6 from pressing on the upper surface of the "I"-shaped slider 5 and affecting the sliding of the "I"-shaped slider 5.

[0053] Example 8

[0054] On the basis of Example 7, in order to drain away the dust and accumulated water on the upper surface of the base 6, the present application also has a collecting groove 19 provided in the middle of the boss 17, and a plurality of evenly distributed sieve holes 20 are provided through the bottom of the collecting groove 19 to drain away the dust or accumulated water on the upper surface of the base 6. An annular flange 21 is fixedly connected to the edge of the lower surface of the base 6 to ensure that there is a gap between the lower surface of the base 6 and the ground. The surface of the annular flange 21 is provided with a plurality of notches 22 distributed in a circular array to reduce the overall weight of the base 6.

[0055] Embodiment 9

[0056] On the basis of Example 8, in order to strengthen the strength of the base 6, the present application also has reinforcing ribs 23 fixedly connected to the lower surface of the base 6. The reinforcing ribs 23 are arranged around the collecting groove 19 to reinforce the surface strength of the base 6. The bottom thickness of the collecting groove 19 is greater than the thickness of the base 6, ensuring that the collecting groove 19 itself has high strength and will not be damaged due to the excessive weight of the emergency items.

[0057] Example 10

[0058] On the basis of the ninth embodiment, in order to reduce the possibility of the dust cover 7 being torn when deformed, the dust cover 7 of the present application is made of a strip of elastic cloth spirally wound (such as Figure 1As shown), and the adjacent edges are sewn together and fixed, the spiral direction of the dustproof cloth cover 7 is opposite to the spiral direction of the spring element 2, ensuring that when the dustproof cloth cover 7 is stretched, the direction of its deformation is the same as the direction of its own length, thereby reducing the possibility of the dustproof cloth cover 7 being torn.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
