Description

Technical Field

[0001] The utility model belongs to the technical field of parasols, and particularly relates to a parasol with adjustable size. Background Art

[0002] Parasols, also known as sun umbrellas, are umbrellas used to block direct sunlight. They effectively shield the skin from UV rays and are therefore widely used in the summer. However, existing parasols are difficult to adjust when unfolded, making them unsuitable for use in different environments. This problem has become a pressing issue for those skilled in the art. Utility Model Content

[0003] The purpose of the present invention is to provide a parasol with adjustable size for existing devices, so as to solve the problems raised in the above background technology.

[0004] The yoke is provided with an adjustable seat, and the adjustable seat is provided with an adjustable yoke, and an adjustable yoke is provided with an adjustable yoke, and an adjustable yoke is provided with an adjustable yoke.

[0005] Furthermore, a number of positioning blocks are distributed at equal intervals inside the support rod, and the top of a positioning block abuts against the bottom of the support block, which facilitates positioning of the support blocks at different heights.

[0006] Furthermore, the positioning block forms a telescopic structure through the reset spring and the accommodating groove, and one end of the positioning block is a "T"-shaped structure when viewed from above, which facilitates the reset spring to drive the positioning block to reset and slide, and avoids the positioning block from falling off.

[0007] Furthermore, the bottom of the other end of the positioning block is arc-shaped, which facilitates the compression deformation of the return spring after the positioning block is squeezed.

[0008] Furthermore, the top of the movable rod is rotatably connected to the fixed block via a shaft, and the fixed block is a "concave" shaped structure, which facilitates the movable rod to drive the fixed block to rotate via the shaft.

[0009] Furthermore, the bottom of the movable rod is rotatably connected to the support block via a shaft, and grooves are provided on the outer wall of the support block at equal angles, which facilitates the support block to drive the movable rod to rotate via the shaft.

[0010] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0011] By providing the support rod, umbrella ribs, umbrella cloth, fixed block, movable rod, support block, accommodating groove, return spring and positioning block, it is convenient to position the support block at different heights, so that the support block drives the umbrella ribs to unfold at different angles through the movable rod, which facilitates the adjustment of the unfolding size of the umbrella cloth, is suitable for different environments, increases the scope of application, meets people's work needs, and is worthy of promotion and use.

[0017] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0018] See also Figure 1-3When the umbrella is folded, the umbrella 2 is lifted up and the umbrella 2 is lifted, and the umbrella 2 is lifted and lowered, so that the umbrella 2 can be opened and lowered easily.

[0019] Furthermore, a number of positioning blocks 9 are distributed at equal intervals inside the support rod 1, and the top of a positioning block 9 abuts against the bottom of the support block 6, which facilitates the positioning of the support block 6 at different heights.

[0020] Furthermore, the positioning block 9 forms a telescopic structure with the accommodating groove 7 through the reset spring 8, and one end of the positioning block 9 is a "T"-shaped structure when viewed from above, which facilitates the reset spring 8 to drive the positioning block 9 to reset and slide, and avoids the positioning block 9 from falling off.

[0021] Furthermore, the bottom of the other end of the positioning block 9 is arc-shaped, which facilitates the compression deformation of the return spring 8 after the positioning block 9 is squeezed.

[0022] Furthermore, the top of the movable rod 5 is rotatably connected to the fixed block 4 via a shaft, and the fixed block 4 is a "concave" shaped structure, which facilitates the movable rod 5 to drive the fixed block 4 to rotate via the shaft.

[0023] Furthermore, the bottom of the movable rod 5 is rotatably connected to the support block 6 via a shaft, and grooves are provided on the outer wall of the support block 6 at equal angles, which facilitates the support block 6 to drive the movable rod 5 to rotate via the shaft.

[0024] When in use, first, the support block 6 is toggled to slide along the outer wall of the support rod 1, so that the support block 6 squeezes the arc slope at the bottom of a positioning block 9 to make it slide, so that a positioning block 9 drives the return spring 8 to compress and deform, and at the same time, the support block 6 drives the movable rod 5 to rotate through the shaft, so that the fixed block 4 is driven to rotate through the shaft, so that the fixed block 4 drives the umbrella rib 2 to rotate around the top of the support rod 1 and then unfold, thereby facilitating the unfolding of the umbrella cloth 3. When the support block 6 slides over a positioning block 9, the elasticity of the return spring 8 will drive the positioning block 9 to return to slide, so that the positioning block 9 supports the support block 6 to prevent the support block 6 from sliding down, and the equidistant distribution of the positioning blocks 9 makes it possible to position the support block 6 at different heights, thereby facilitating the adjustment of the unfolding range of the umbrella cloth 3, which is conducive to sunshade work of different sizes and improves the scope of application.
