[0035] Example

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the present embodiment provides an umbrella folding tube, comprising an outer tube 10, an inner tube 20 and an umbrella binding member 30, the inner tube 20 is rotatably arranged in the outer tube 10, a mushroom-head type connecting protrusion 201 is arranged on the outer bottom surface of the inner tube 20, a spring 202 is arranged between the outer bottom surface of the inner tube 20 and the inner bottom surface of the outer tube 10, and a locking member 203 for pressing to clamp or press to separate is arranged on the inner bottom surface of the outer tube 10; the umbrella binding member 30 comprises a semi-annular cover sheet 301 which is symmetrically and axially hingedly arranged on the outer side surface of the tube mouth of the inner tube 20, a pull rope 302 is arranged on the semi-annular cover sheet 301 (the pull rope 302 is in a straightened state, and the pull rope 302 can be a fishing line with strong toughness, that is, a four-color line in a nylon line; it can also be an elastic rope with less elasticity, etc.), and one end of the pull rope 302 passes through the inner tube 20 and is arranged on the outer tube 10.

[0037] Specifically, the folded umbrella is inserted into the inner tube 20, and the inner tube 20 or the outer tube 10 is rotated so that the inner tube 20 is stored in the outer tube 10. At the same time, during the rotation, the semi-ring cover sheet 301 (a half-ring structure) is pulled by the pull rope 302, and then turned over to cover the tube mouth of the inner tube 20. During the turning and covering process, the umbrella can be bound so that the umbrella can be smoothly placed in the inner tube 20.

[0038] Further, after the inner cylinder 20 rotates into the outer cylinder 10, the connection protrusion 201 on the bottom surface of the inner cylinder 20 will engage with the locking piece 203 (the locking piece 203 is a push-type lock, such as the push-type lock of the da-xa model produced by Dreamamba). In order to reflect the adaptability, the locking piece 203 can be rotatably installed on the bottom plate of the outer cylinder 10 through the bearing, so as to improve the locking force between the inner cylinder 20 and the outer cylinder 10. When taking out the umbrella, the connection protrusion 201 is pulled out by rotation, and at the same time, the outer cylinder 10 and the inner cylinder 20 are no longer engaged with the thread 204 (that is, there is a section of thread 204 between the outer cylinder 10 and the inner cylinder 20), so that the inner cylinder 20 can be ejected by the spring 202; and the semi-ring cover sheet 301 can be turned over and avoided by the torsion spring, so as to easily take out the umbrella, improve the convenience and practicality of use, and will not cause water dripping on the umbrella to affect the cleanliness of the indoor environment, and at the same time avoid the problem of people falling due to the slippery bottom plate.

[0039] In this embodiment, a soft layer, such as a silicone layer or a rubber layer, is disposed outside the semi-ring cover sheet 301, which can improve the outer protective effect of the semi-ring cover sheet 301, that is, avoid scratches on the surface of the umbrella.

[0040] like Figure 4 and Figure 5As shown, in this embodiment, the inner bottom of the outer cylinder 10 is provided with a thread groove 101, and the outer bottom of the inner cylinder 20 is provided with a thread 204 engaged with the thread groove 101. Specifically, the thread 204 is only provided at the bottom of the outer cylinder 10 and the inner cylinder 20, so that the inner cylinder 20 can be screwed together or separated from the outer cylinder 10 by rotating a small arc length, so that the rotation has a good guiding effect and improves practicality.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, two decorative pieces 102 are symmetrically arranged on the outer top of the outer tube 10, and one end of the pull rope 302 is arranged on the decorative piece 102. The decorative piece 102 can be rectangular, circular or regular polygonal, or other self-designed shapes, such as crescent, pentagon, wave, flower or leaf, etc. The decorative piece 102 can be used to cover the fixed position of the pull rope 302 on the outer tube 10 and decorate it at the same time, thereby improving the aesthetic appearance of the closed umbrella tube.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment, a protrusion 3011 for tying the other end of the pull rope 302 is provided at the middle position of the semi-ring cover sheet 301, and a notch 205 is provided on the tube mouth of the inner tube 20 to correspond to the protrusion 3011. Specifically, a hole can be punched or an annular groove can be designed on the protrusion 3011 so that the pull rope 302 can be tied and fixed and not easily separated. At the same time, the design of the notch 205 can accommodate or avoid the pull rope 302 and the protrusion 3011, so that the semi-ring cover sheet 301 can be horizontally covered on the tube mouth of the inner tube 20.

[0043] like Figure 5 As shown, in this embodiment, the locking element 203 includes a fixed cylinder 2031, a clamping block 2032 axially movably sleeved in the fixed cylinder 2031, and a return spring 2033 connected between the clamping block 2032 and the fixed cylinder 2031, and one end of the clamping block 2032 is provided with a plurality of elastic claws 2034 for clamping the connecting protrusion 201; the distance between the connecting protrusion 201 and the elastic claws 2034 is smaller than the distance between the through hole on the inner cylinder 20 for the pull rope 302 to pass through and the cylinder mouth.

[0044] Specifically, when the connection protrusion 201 abuts against the elastic clamping claw 2034, the clamping claw 2032 is pushed into the fixed cylinder 2031. At this time, the elastic clamping claw 2034 is affected by the inner diameter of the fixed cylinder 2031 and shrinks inward until the connection protrusion 201 is clamped, and the inner cylinder 20 is fixed. When the inner cylinder 20 is reversed, the clamping claw 2032 is separated from the fixed cylinder 2031 by the elastic force of the reset spring 2033 and the spring 202, and the elastic clamping claw 2034 is separated, and then the inner cylinder 20 is ejected out of the outer cylinder 10, so as to achieve the purpose of locking or separating the inner cylinder 20.

[0045] like Figure 5 As shown, in this embodiment, a mounting groove 206 for mounting the locking member 203 is provided on the inner bottom surface of the outer cylinder 10, and the mounting groove 206 is arranged in alignment with the connecting protrusion 201. The design of the mounting groove 206 can position and install the locking member 203 to ensure that the locking member 203 and the connecting protrusion 201 are accurately positioned, which is convenient for production and installation.

[0046] like Figure 4 and Figure 5 As shown, in this embodiment, the outer cylinder 10 includes a cylinder body 103 and a bottom cover 104 disposed on the bottom of the cylinder body 103, the mounting groove 206 is integrally formed with the bottom cover 104, and the bottom cover 104 can be glued or screwed to the cylinder body 103. This makes it easy to install the spring 202 and the locking piece 203, reduces the difficulty of assembly, and also facilitates disassembly and maintenance in the later stage, thereby improving practicality.

[0047] In this embodiment, the distance between the through hole for the pull rope 302 to pass through and the tube mouth of the inner tube 20 is greater than the arc length of the 60° angle of the inner tube 20. That is, by designing the length of the pull rope 302, the semi-ring cover sheet 301 can be pulled well, and the pull rope 302 will not be too long or too short, and can be pulled in coordination with the rotation, thereby improving practicality.

[0048] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
