Description

Technical Field

[0001] This utility model relates to the field of umbrella technology, specifically to a corner connector for umbrellas. Background Technology

[0002] Umbrella corner connectors are components used in outdoor equipment such as folding umbrellas and walking stick umbrellas to achieve multi-angle rotational connection between the umbrella ribs and the canopy, or between the umbrella ribs themselves. Their core function is to allow the canopy to be flexibly adjusted according to wind direction and sunlight angle through a universal joint structure, while maintaining stable support.

[0003] Featuring a ball joint design, the umbrella body can rotate freely in multiple directions. Typically made of stainless steel or aluminum alloy, it is lightweight and corrosion-resistant. Some models are equipped with a snap-on installation structure for easy and quick attachment of the ribs to the canopy. Primarily used in portable devices such as fishing umbrellas and walking stick umbrellas, it solves the problem of blind spots in sunshade caused by traditional fixed-angle connections, improving flexibility and comfort during outdoor use. Traditional corner connectors for umbrellas have the following drawbacks: (1) When using the corner connectors for traditional umbrellas, the umbrellas will sway left and right when encountering strong winds because the traditional corner connectors cannot fix the angle, making the umbrellas unstable. (2) When using corner connectors for traditional umbrellas, the corner connectors cannot be rotated at will, which makes it impossible to adapt to the sun angle at any time. Utility Model Content

[0004] The purpose of this utility model is to provide a corner connector for umbrellas, in order to solve the problems mentioned in the background art, such as the inability of traditional corner connectors to fix the angle, causing the umbrella to sway left and right in strong winds, resulting in instability; and the inability of traditional corner connectors to adapt to the sun's angle at any time, as they cannot be rotated freely.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner connector for umbrellas, comprising a main clamping block, a connecting bottom block fixedly connected to the bottom of the main clamping block, an inner placement hole being formed in the connecting bottom block, an outer hole one and an outer hole two being sequentially formed on the top surface of the main clamping block, a rotating shaft one and a rotating shaft two being sequentially engaged within the outer hole one and the outer hole two, two inner rotating blocks being sleeved on the surface of the rotating shaft two, the two inner rotating blocks being arranged opposite each other, a clamping block being fixedly connected to the opposite side of each of the two inner rotating blocks, multiple tooth grooves being formed on the top of each of the two clamping blocks, a gear block being sleeved on the surface of the rotating shaft one, the multiple tooth grooves being engaged with the surface of the gear block, a telescopic spring being engaged with the inner side of the inner placement hole, the two ends of the telescopic spring being engaged with the inner side of the two clamping blocks respectively, and an outer protective block being engaged with the surface of the main clamping block, the outer protective block being used to stabilize the force between the clamping teeth and the tooth grooves.

[0006] Preferably, the bottom of the connecting block is provided with a threaded groove, and a threaded block is threadedly connected in the threaded groove. The threaded block is used to connect the chassis structure.

[0007] Preferably, a chassis is fixedly connected to the bottom of the threaded block, and a clamping block is fixedly connected to the bottom of the chassis. The clamping block is used to connect to the external structure.

[0008] Preferably, a connecting rod is fixedly connected to the top of the gear block, and an outer ring block is fixedly connected to the top of the connecting rod. The connecting rod is used to fix the corner connecting strip.

[0009] Preferably, a corner connecting strip is fixedly connected to the top of the outer ring block, and the corner connecting strip is used to connect to the external structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: After the clamping block is fixed with multiple toothed grooves and gear blocks, the toothed grooves and gear blocks may disengage when the corner connecting strip bears a large weight, causing the corner to be unstable. After adding an outer protective block, the force between the toothed grooves and gear blocks is stabilized, solving the problem of insufficient umbrella stability. When adjusting the angle of the corner connecting piece, the corner connecting strip is rotated and fixed by multiple toothed grooves and gear blocks, which can make the umbrella adapt to the sun angle.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 This utility model provides a corner connector for umbrellas, including a main clamping block 1. A connecting bottom block 4 is fixedly connected to the bottom of the main clamping block 1. An inner placement hole 5 is opened in the connecting bottom block 4. An outer hole 2 and an outer hole 3 are sequentially opened on the top surface of the main clamping block 1. A rotating shaft 19 and a rotating shaft 20 are sequentially engaged in the outer holes 2 and 3. Two inner rotating blocks 11 are sleeved on the surface of the rotating shaft 20. The two inner rotating blocks 11 are arranged opposite each other. A clamping block 10 is fixedly connected to the opposite side of the two inner rotating blocks 11. Multiple toothed grooves 12 are opened on the top of the two clamping blocks 10. A gear block 14 is sleeved on the surface of the rotating shaft 19. The multiple toothed grooves 12 are engaged with the surface of the gear block 14. A telescopic spring 13 is engaged in the inner placement hole 5. The two ends of the telescopic spring 13 are engaged with the inner side of the two clamping blocks 10 respectively. An outer protective block 18 is engaged in the surface of the main clamping block 1.
