Description

Technical Field

[0001] This utility model belongs to the field of automatic umbrellas, and in particular relates to a buttonless spring-concealed automatic umbrella. Background Technology

[0002] In the field of automatic umbrellas, traditional automatic umbrellas are widely popular due to their ease of opening and closing, but they have many problems in actual use: In terms of specifications, traditional automatic umbrellas are relatively limited. The canopy diameter is mostly fixed at a few sizes, failing to meet the needs of different users. During heavy rain, small-diameter umbrellas provide insufficient protection, leaving users easily soaked; while large-diameter umbrellas offer good protection, they are inconvenient to carry and store, especially in crowded places or when placed in a backpack. Furthermore, their overall length and folded size lack flexibility; long umbrellas are prone to colliding with surrounding objects, and their large folded size causes significant inconvenience for frequent travelers and those carrying many items.

[0003] From a mechanical perspective, the traditional button-operated opening and closing design of automatic umbrellas has many drawbacks. Frequent button operation can easily cause internal mechanical parts to wear out and deform, and over time, their sensitivity will decrease or even fail, causing the automatic umbrella to fail to open and close properly.

[0004] In terms of appearance and ease of operation, the protruding buttons detract from the umbrella's aesthetics and are prone to accidental activation while carrying, causing the automatic umbrella to open or close unexpectedly. Operating the buttons is extremely inconvenient in busy or crowded situations.

[0005] In terms of safety and service life, exposed springs are susceptible to corrosion from rain, moisture and dust. After rusting and corrosion, their elasticity deteriorates, their lifespan is shortened, and they may even break and pop out, endangering the safety of users. Utility Model Content

[0006] The purpose of this utility model is to provide a buttonless, spring-loaded, concealed automatic umbrella, aiming to solve the problems existing in the background art. To achieve this purpose, the technical solution adopted by this utility model is: A buttonless spring-loaded concealed automatic umbrella includes a rib assembly, a pulley assembly, a spring, a center rod, an upper nest, a middle nest, a lower nest, a sleeve, a handle, and a functional ring. The center rod has a spring inside, an upper nest at the top, a middle nest in the middle, a sleeve below the upper nest, a lower nest at the tail, and a handle at the bottom. A pulley assembly is located between the handle and the upper nest, with a rope in the pulley assembly connected to the middle nest.

[0029] Working principle: When the umbrella needs to be opened, pull down the functional ring. The third protrusion inside the functional ring presses down on the tail of the spring clip, causing the head of the spring clip to lift up. The lower canopy, which was previously held in place by the head of the spring clip, is unlocked. At this time, the first spring inside the central rod releases its elastic force. The first spring pushes the central canopy upward along the central rod. During the movement of the central canopy, through its connection with the rope in the pulley assembly, the first and second pulleys change the direction of the force, driving the rope to move. The movement of the rope then pulls the umbrella rib assembly connected to it, causing the umbrella ribs to unfold upward about the connection point with the upper canopy. The first and second ribs cooperate with the umbrella ribs, the central canopy, and the fixing components, respectively. As the central canopy rises, the first rib pushes the umbrella ribs to unfold, and the second rib further assists in the support, allowing the umbrella canopy to gradually open to a fully open state.

[0030] When you need to close the umbrella, pull the function ring down again to repeat the unlocking action of the lower canopy. Then, manually overcome the elasticity of the first spring and push the middle canopy down. The middle canopy moves the rope in the opposite direction, which, through the pulley assembly, causes the umbrella rib assembly to move in the opposite direction, and the umbrella ribs gradually close. After the umbrella ribs are closed to the appropriate position, release the function ring. The function ring resets under the action of the second spring, and the third protrusion inside the function ring body abuts against the spring head again. The spring locks the lower canopy, fixing the umbrella in the closed position, completing the entire umbrella closing process.

[0031] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
