The limiting plane 208 is formed at the junction of the bottom of the limiting salient point 214 and the inner concave surface 207, and the limiting plane 208 is matched with the limiting plane at the lower end of the outer rod, so that the middle rod 2 can be prevented from being pulled off.
However, the limiting structure has the advantages that the size of the limiting salient points is small, the stress area is small, the stress surface is not perpendicular to the axis of the umbrella rod, and the limiting structure is easy to wear and deform after being used for many times, so that the limiting failure is caused, and the service life of a product is shortened. In addition, the limit salient point is formed by punching again after the umbrella rod is processed and formed, so that one more processing technology is added, and the manufacturing cost of the product is increased.
Disclosure of Invention
The utility model aims to solve the technical problem existing in the prior art and aims to provide an end enhanced umbrella rod.
In order to solve the above problem, the utility model adopts the following technical scheme: an end part enhanced umbrella rod is provided with an outer umbrella rod connecting end and an inner umbrella rod connecting end, one side surface is a guide surface used for being connected with the outer umbrella rod, the main body part of the guide surface is provided with an inner concave surface, and the end part enhanced umbrella rod is characterized in that the outer umbrella rod connecting end of the inner concave surface is provided with a limiting bulge, and the limiting bulge penetrates through the end surface of the end part.
The utility model discloses an end enhancement mode umbrella pole adopts the spacing arch of lining up the terminal surface to replace traditional spacing bump, because bellied shape and size is big, has not only increased the area of spacing face to strengthen the bulk strength of tip greatly, therefore can not produce the deformation in the use. Meanwhile, the limiting surface formed by the limiting bulge can be ensured to be perpendicular to the plane of the umbrella rod, so that the abrasion is reduced, the limiting is ensured, and the service life of the product is prolonged.
The limiting protrusions can be formed simultaneously with the concave surfaces, the original shape of the umbrella rod can also be utilized, only the concave surfaces of the main body parts of the guide surfaces are processed on the original rod of the umbrella rod, and the unprocessed parts on the original rod naturally form the limiting protrusions, so that the processing steps of the umbrella rod are reduced, the manufacturing process is simplified, and the manufacturing cost is reduced.
The limiting bulge can be any shape structure.
Preferably, the limiting bulge is in the initial shape of the original pole of the umbrella pole.
More preferably, the limiting protrusion is arc-shaped.
The umbrella pole is any one inboard umbrella pole of a set of adjacent telescopic link.
The umbrella rod is a middle rod and/or an inner rod in the three-section rod. The upper end of the outer rod in the three-section rod is directly connected with the upper disk, so that a limiting bulge is not needed.
The umbrella rod is any one of an outer rod, a middle rod and an inner rod in the four-section rod. The upper end of the outer rod in the four-section rod is directly connected with the upper disk, so that a limiting bulge is not needed.

Detailed Description
Fig. 1, 2 and 3 are schematic structural views of a conventional center pole, and the defects thereof have been described above and are not described again.
Referring to fig. 4-8, the utility model relates to an end enhanced umbrella rod. In the present embodiment, the umbrella rod is a middle rod 2 of a three-section telescopic rod. However, the utility model is not limited to the middle pole, and any one of the telescopic rods that need to be connected with the outside umbrella pole can be adopted by the utility model discloses a technical scheme, and all belong to the utility model discloses a within range.
The middle rod 2 is provided with an outer umbrella rod (namely, an outer rod 1) connecting end 231 and an inner umbrella rod (namely, an inner rod 3) connecting end 232, one side surface is a guide surface 201 for connecting with the outer umbrella rod, the main body part of the guide surface 201 is provided with an inner concave surface 207, the outer umbrella rod connecting end 231 of the inner concave surface 207 is provided with a limiting bulge 233, and the limiting bulge 233 penetrates through the end surface of the end.
The junction of the bottom of the limiting projection 233 and the top of the inner concave surface 207 forms a limiting surface 208. The limiting surface 208 can prevent the middle rod 2 from being pulled out of the outer rod 1.
The limiting protrusion 233 can be formed with the inner concave surface 207 at the same time, or the original shape of the umbrella rod can be utilized, only the inner concave surface of the main body part of the guide surface is processed on the original rod of the umbrella rod, and the unprocessed part of the original rod naturally forms the limiting protrusion, thereby reducing the processing steps of the umbrella rod, simplifying the manufacturing process and reducing the manufacturing cost.
The limiting bulge can be any shape structure.
Preferably, the limiting bulge is in the initial shape of the original pole of the umbrella pole.
