[0029] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, can be fixedly connected, can be detachably connected, or can be integrated; can be directly connected, or can be indirectly connected through an intermediate medium; can be the communication or interaction relationship between two elements. However, it is noted that direct connection means that the connection between the two main bodies does not form a connection relationship through a transition structure, but is connected only through a connection structure to form a whole. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] Example 1

[0032] like Figures 1-2 As shown, a fixing structure for an umbrella head 2 and a center rod 1 includes a center rod 1 and an umbrella head 2. The umbrella head 2 is fixedly connected to the center rod 1 via an external thread connector 3. The external thread connector 3 is threadedly connected to the umbrella head 2. The external thread connector 3 has an abutting surface on the threaded portion. The external thread connector 3 has a first insertion hole 6 on the abutting surface portion. The center rod 1 has a second insertion hole 7. The external thread connector 3 is provided with a snap-fit ​​component 4, which includes a snap pin 5 and a limiting part. The snap pin 5 is inserted into the first insertion hole 6 and the second insertion hole 7, and the limiting part abuts against the abutting surface.

[0033] By adopting the above technical solution, the relative movement between the external thread connector 3 and the middle rod 1 can be restricted by inserting the locking pin 5 part on the locking member 4 into the first insertion hole 6 and the second insertion hole 7. The limiting part can restrict the locking pin 5 from continuing to move into the middle rod 1 by abutting with the abutting plane, so that it can be locked in the first insertion hole 6 and the second insertion hole 7. After the locking member 4 is locked into the first insertion hole 6 and the second insertion hole 7, the threaded connection between the umbrella head 2 and the external thread connector 3 can be used to prevent the locking member 4 from exiting the first insertion hole 6 and the second insertion hole 7. A placement space for the limiting part to enter can be formed between the umbrella head 2 and the abutting plane. Therefore, it does not affect the threaded connection between the umbrella head 2 and the external thread connector 3. By the joint blocking of the limiting part and the umbrella head 2, the locking pin 5 is limited, thereby realizing the connection between the middle rod 1 and the umbrella head 2.

[0034] The central rod 1 includes several sleeves 12, which are nested sequentially, and adjacent sleeves 12 are slidably connected to each other. This arrangement allows the structure to also be used in folding umbrellas.

[0035] The sleeve 12 with the largest diameter is connected to the external thread connector 3. By setting the umbrella head 2 on the sleeve with the largest diameter, the limiting part can block the locking pin 5, preventing it from entering the interior of the sleeve 12 and keeping it inside the tube wall of the sleeve 12. This ensures that there are no obstructions inside the sleeve 12, and the adjacent sleeves 12 can be completely inserted into the sleeve 12 connected to the umbrella head 2. This allows the folding umbrella to maintain a shorter storage length when folded, while ensuring the overall length of the central rod 1 when unfolded.

[0036] Example 2

[0037] like Figure 3 As shown, the limiting part is in the shape of an arc-shaped column, and the length of the arc-shaped column 10 is greater than the diameter of the locking pin 5. The horizontal surface of the arc-shaped column 10 is attached to the abutment plane. The locking pin 5 is limited by the arc-shaped column 10, which is longer than the locking pin 5. The bottom of the arc-shaped column 10 is flat and can be attached to the abutment plane. This type of locking part 4 is also a commonly used part in folding umbrellas. It is often used to limit the relative rotation between the sleeves 12. It can be applied to the locking part 4 in this application with simple modifications, which can reduce the mold opening cost. At the same time, the cylindrical surface on the arc-shaped column 10 can also facilitate the limiting part to be attached to the threaded hole surface of the umbrella head 2.

[0038] Both ends of the arc-shaped column 10 are chamfered 11. The chamfers 11 at both ends of the arc-shaped column 10 prevent damage to the threads at both ends of the arc-shaped column 10 during the threaded connection between the umbrella head 2 and the external thread connector 3.

[0039] Example 3

[0040] like Figure 4 As shown, the sleeve 12 with the largest diameter is connected to the upper nest, and the sleeve 12 with the smallest diameter is connected to the umbrella head 2.

[0041] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
