Description

Technical Field

[0001] This utility model relates to the field of fishing gear accessories, and in particular to an umbrella frame. Background Technology

[0002] Fishing, as a recreational activity that can both cultivate one's mind and provide enjoyment, is becoming increasingly popular. During fishing, the need for sunshade and an umbrella is inevitable. However, umbrellas typically require a stand, which makes them bulky and takes up a lot of space when carried.

[0003] To address this, a lightweight umbrella frame that can be mounted on external components such as fishing box carriers has been proposed. The product can be folded up by bending, reducing the space it occupies. Utility Model Content

[0004] This utility model aims to solve the above-mentioned technical problems by providing an umbrella frame.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An umbrella frame, comprising:

[0007] The clamping member has a mounting through hole and a rectangular groove. The mounting through hole is formed by a first side wall portion and a second side wall portion being limited by an annular portion. A side opening is provided on one side of the mounting through hole. There is an opening space between the first side wall portion and the second side wall portion, which respectively connects the side opening and the mounting through hole. The rectangular groove is located below the mounting through hole.

[0008] The mounting component moves axially within a rectangular groove. The mounting component has an arc-shaped surface that adapts to the rectangular groove, and the two sides of the arc-shaped surface are limiting surfaces that limit the rectangular groove. The mounting component moves 90° within the rectangular groove through the arc-shaped surface.

[0009] Preferably, the bottom end of the clamping member is provided with a protrusion forming a rectangular groove, and the lower part of the second side wall is connected to the protrusion via a connecting part.

[0010] Preferably, the first sidewall portion and the second sidewall portion are connected by fasteners, and the opening space between the first sidewall portion and the second sidewall portion is adjusted by fasteners to tighten the mounting through hole.

[0011] Preferably, the bottom end of the mounting component is also provided with a positioning part.

[0012] Preferably, the annular portion, the first sidewall portion, and the second sidewall portion are integrally connected.

[0013] Preferably, the fastener includes a nut, a threaded rod adapted to the nut, and a torque handle mounted on the threaded rod.

[0014] Preferably, the positioning part has bolt holes.

[0015] The beneficial effects of this utility model are as follows: The structure is highly integrated and easy to use. The umbrella frame can be fixed by two or more structural units. The adjustment of the tightness of a general umbrella frame corresponds to the rod of a standard umbrella frame. Secondly, the folding of the clamping part is controlled by unidirectional shaft movement, which reduces space occupation. Finally, when the clamping part is subjected to the swinging force, the rectangular groove fits against the lateral limiting surface of the mounting part, moves through the fitted rounded corner surface, and forms an interaction force with the rounded corner surface, moving to the vertical limiting surface of the mounting part, which is only limited by the mutual limiting between the rectangular surface structures.

[0017] Figure 2 This is a schematic diagram of the clamping component structure of this utility model;

[0018] Figure 3 This is the second structural schematic diagram of the present invention. Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] according to Figures 1-3 As shown, this structure provides an umbrella frame, which is an auxiliary tool for fixing a sun umbrella. It can be installed in a fishing environment and includes a clamping part 1 and a mounting part 2. The clamping part 1 has a mounting through hole 11. The tightness of the mounting through hole 11 is adjusted to control the fixing and disassembly of the sun umbrella. The mounting part 2 is installed on one side of the clamping part 1 and is installed on the external end as an extension of the clamping part 1.

[0021] As shown in the figure, the clamping part 1 is axially connected to the mounting part 2. After the mounting part 2 is fixedly installed, the clamping part 1 swings on the fixed axis of the mounting part 2. A set of symmetrical arc-shaped protrusions 12 extend from the bottom end of the clamping part 1, and the mounting part 2 is assembled on the protrusions 12 through the shaft hole 100. Therefore, there is a through hole 200 on the mounting part 2 that fits through the shaft hole 100. The protrusions 12 and the bottom end of the clamping part 1 are rectangular grooves 300. The clamping part 1 rotates 90° on the mounting part 2. In the figure, the mounting part 2 is a rectangular body with a rounded corner 400. When the clamping part 1 is subjected to the swinging force, the rectangular groove 300 fits against the lateral limiting surface 500 of the mounting part 2, moves through the surface of the rounded corner 400, and forms an interaction force with the surface of the rounded corner 400, and moves to the vertical limiting surface 600 of the mounting part 2.

[0022] In this structure, the bottom end of the mounting part 2 is also provided with a positioning part 21. The positioning part 21 is cylindrical and can be snapped onto an external part with a positioning hole. Specifically, it can be a stand or a fish box or other equipment. It should be noted that the installation method is welding. Of course, bolt holes can also be opened in the positioning part 21 and fixed to the external part with screws.

[0023] As shown in the figure, when it is a planar opening, the axial direction of the mounting through hole 11 is perpendicular to the axial direction of the shaft hole 100. The mounting through hole 11 is a tightening adjustment type. A side opening 13 is provided on one side of the mounting through hole 11. The mounting through hole 11 is formed by an annular portion 101, a first side wall portion 102 extending from the annular portion 101, and a second side wall portion 103 opposite to the first side wall portion 102. The side opening 13 is located below the first side wall portion 102, and is connected by the first side wall portion 102 and the second side wall portion 103. In the figure, the umbrella handle is tightened by gradually narrowing the opening space 14 between the first sidewall portion 102 and the second sidewall portion 103 through fasteners. For this purpose, the first sidewall portion 102 and the second sidewall portion 103 have fixing holes and mating holes. It should be noted that the second sidewall portion 103 is fixed and connected to the protrusion 12 through the connecting portion 3. In contrast, the first sidewall portion 102 is movable. Therefore, the outer shape of the second sidewall portion 103 is larger than that of the first sidewall portion 102.

[0024] It should be noted that the annular portion 101, the first sidewall portion 102 extending from the annular portion 101, and the second sidewall portion 103 opposite to the first sidewall portion 102 are integrally connected.

[0025] Therefore, the fastener includes a nut, a threaded rod that fits the nut, and a torque handle mounted on the threaded rod. Since the second side wall portion 103 is fixed, the nut is preferably mounted on the second side wall portion 103.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
