Problems solved by technology

[0003] 1. Two-section design, the upper and lower main rods are placed separately, easy to lose:
[0004] The above-mentioned common beach umbrella has a two-section design for the main pole. After the main pole is disassembled, it is placed separately. If you want to use it again after a long time, you often forget where it is placed, so it is lost and cannot be used again.
[0005] 2. Two-section design, generally women and children cannot be assembled separately:
[0006] The commonly used beach umbrella mentioned above has a two-section design for the main pole. When assembling, the upper main pole is usually stretched out first, and then the lower end of the upper main pole is inserted into the lower main pole. The center of gravity of the umbrella surface is often unstable, it is difficult to control women and children, and it is easy to cause shaking. In addition, the beach is open and windy, which makes the open umbrella surface and the main pole shake more violently due to the wind. Generally, it is difficult for women and children to assemble successfully
[0007] 3. The diameter of the main pole of the beach umbrella is too large, so it cannot be directly converted to the telescopic design of the general small umbrella:
[0008] To sum up, among the current small umbrellas, although the main rod can be designed to be retractable, the diameter of the main rod of the small umbrella is between 8 and 12 mm, and the thickness of the tube wall is between 0.5 and 0.8 mm. It is easy to process the longitudinal guide groove used for rolling the telescopic guide on the main pole of the umbrella; however, the main pole of this kind of beach umbrella has a diameter of more than 20mm, a thickness of the tube wall of more than 1.2mm, and a longer length. More than 1.5 meters, and due to the small demand, there is no research and development of relative processing equipment for processing, and the usual beach umbrellas are designed with a two-section structure, which cannot be directly transferred to the telescopic structure of ordinary small umbrellas.
[0009] 4. Moreover, in order to avoid lightning strikes on the beach, the middle pole of general beach umbrellas is made of non-conductive glass fiber tubes. The glass fiber tubes cannot be rolled into the longitudinal guide grooves used for telescopic guides in the manufacturing process. The telescopic structure of the small umbrella cannot be reused, which is the main reason why the middle pole of the beach umbrella has been made into a two-section joint structure for a long time

Embodiment Construction

[0045] First, please refer to Fig. 1 to Fig. 8, the first preferred embodiment of the retractable beach umbrella of the present invention includes an umbrella body B and a telescopic main rod A that can support the umbrella body B, wherein the telescopic main rod A is scalable its length, to change the height of the support umbrella body B such as figure 2 As shown, wherein the telescopic main rod A includes:

[0046] An outer tube 10, the outer tube 10 is connected with the umbrella nest of the umbrella body B, and is used to support the entire umbrella body B to form a stretch; the bottom of the outer tube is provided with a stop ring 11, and its end has a reduced diameter portion 110, which The inner diameter is smaller than the inner diameter of the outer pipe 10, so as to prevent the telescopic pipe from being separated from the outer pipe;

[0047] A telescoping tube 20, such as image 3 , 4 As shown, the bottom end of the telescopic tube 20 is a tapered tapered porti...

Abstract

A telescopic seabeach umbrella features use of the stepless telescopic and locating upper supporting rod, lower supporting rod, fastener between them, and C-shaped fastening block. Its height can be regulated as will.

Description

technical field [0001] The invention relates to a retractable beach umbrella, in particular to a beach umbrella which can make the main rod of the umbrella freely expandable and short in length and height. Background technique [0002] According to the current beach umbrellas, as shown in Figure 16, most of them are made into large-scale umbrella structures, so that the function of sunshade and summer heat can be achieved, and the basic structure of general beach umbrellas mostly uses thick iron rods as the main rod, and is placed on the main rod. The bottom of the pole is tapered to facilitate insertion and fixation on the beach; and for the convenience of carrying, the main pole is made into two separate types, the upper main pole R1 and the lower main pole R2, and the upper main pole is inserted when needed. Insert it into the lower main pole, and then assemble the two main poles into a long pole by means of the fastener B; the current design of this beach umbrella has th...
