Abstract
Description
Technical Field
[0001] This utility model relates to the field of sunshade technology, and in particular to a hand-push sunshade. Background Technology
[0002] Hand-operated parasols are a common outdoor leisure tool, widely used in plazas, beaches, parks, courtyards, and outdoor cafes. A typical hand-operated parasol consists of the parasol itself and a sturdy base for securing it. In use, the parasol is inserted into the base and secured by the base.
[0003] Existing stabilizing bases are usually water tanks. When in use, water is added to the stabilizing base to increase its weight and improve its stability. When not in use, the water is drained to reduce the weight of the stabilizing base, making it easier to move and store.
[0004] In practical use, the larger the diameter of the stable base, the more stable it is. However, as the diameter of the stable base increases, its volume also increases, requiring more space for storage, making it inconvenient to store. Existing stable bases cannot simultaneously achieve both stability and ease of storage. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a hand-push sunshade.
[0006] The purpose of this utility model is achieved through the following technical solution: a hand-push sunshade umbrella, including a hand-push sunshade umbrella body and a stable base, the stable base including a water tank and a base, the base being provided with a receiving cavity, the water tank being disposed in the receiving cavity; a sloping groove transmission mechanism is provided between the water tank and the receiving groove, and an elastic element is provided between the water tank and the bottom of the base; when water is injected into the water tank, the weight of the water tank increases and it moves downward, causing the water tank to rotate through the sloping groove transmission mechanism; several opening and closing flaps are rotatably provided on the side of the base, and a transmission connection mechanism is provided between the opening and closing flaps and the water tank; when the water tank rotates, the opening and closing flaps are driven to rotate through the transmission connection mechanism.
[0007] Preferably, the inclined groove transmission mechanism includes a convex shaft disposed on the outside of the water injection tank and an inclined groove disposed on the inner wall of the base, wherein the convex shaft is engaged in the inclined groove and can slide in the inclined groove.
[0008] Preferably, the base has a take-up and release groove on its side, and a rotating shaft is provided at one end of the take-up and release flap, which is rotatably connected to one end of the take-up and release groove via the rotating shaft.
[0009] Preferably, the transmission connection mechanism includes a cantilever arm disposed on the opening and closing flaps and a follower rod disposed at the bottom of the water injection tank. The cantilever arm is provided with a sliding groove, and the follower rod is inserted into the sliding groove.
[0010] Preferably, the water tank is provided with a sleeve, and a locking screw is connected to the sleeve.
[0011] Preferably, the elastic element is a spring.
[0012] Preferably, the water tank has a cylindrical structure and the accommodating cavity is a cylindrical cavity.
[0013] The beneficial effects of this utility model are as follows: In this utility model, when water is injected into the stable base, the weight of the water tank gradually increases, and the water tank moves downward against the elastic force of the elastic element. When the water tank moves downward, under the action of the inclined groove transmission mechanism, the water tank rotates in one direction. When the water tank rotates, it drives the retractable flaps to rotate outward through the transmission connection mechanism, causing the retractable flaps to open outward. After the retractable flaps open, the equivalent diameter of the base increases significantly, thereby greatly improving the stability of the stable base when it is placed, and improving its wind resistance and overturning resistance. After the stable base is used up, the water in the water tank is drained. At this time, the retractable flaps on the base return to the retracted state, which facilitates the handling and storage of the stable base. The stable base takes into account both stability and storage convenience, greatly improving the use effect. Attached Figure Description

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] like Figures 1 to 6 As shown, a push-type sun umbrella includes a push-type sun umbrella body 1 and a stable base 2. The stable base 2 includes a water tank 2-1 and a base 2-2. The base 2-2 has a receiving cavity, and the water tank 2-1 is disposed in the receiving cavity. A inclined groove 2-2b transmission mechanism is provided between the water tank 2-1 and the receiving groove. An elastic element is provided between the bottom of the water tank 2-1 and the base 2-2. When water is injected into the water tank 2-1, the weight of the water tank 2-1 increases and it moves downward, causing the water tank 2-1 to rotate through the inclined groove 2-2b transmission mechanism. Several retractable flaps 2-3 are rotatably provided on the side of the base 2-2. A transmission connection mechanism is provided between the retractable flaps 2-3 and the water tank 2-1. When the water tank 2-1 rotates, the retractable flaps 2-3 are driven to rotate through the transmission connection mechanism.
[0023] In this invention, when the stable base 2 is not filled with water, the water tank 2-1 is relatively light and is positioned at a higher position in the accommodating cavity under the elastic force of the elastic element; at this time, the opening and closing flaps 2-3 are in a closed state, and the overall diameter of the stable base 2 is small, making it easy to transport and store.
[0024] When water is poured into the stable base 2, the weight of the water tank 2-1 gradually increases. The water tank 2-1 moves downward against the elastic force of the elastic element. When the water tank 2-1 moves downward, under the action of the transmission mechanism of the inclined groove 2-2b, the water tank 2-1 rotates in one direction. When the water tank 2-1 rotates, it drives the opening and closing petals 2-3 to rotate outward through the transmission connection mechanism, so that the opening and closing petals 2-3 open outward. After the opening and closing petals 2-3 open, the equivalent diameter of the base 2-2 increases significantly, thereby greatly improving the stability of the stable base 2 when it is placed, and improving its wind resistance and overturning resistance.
[0025] After use, the water in the water tank 2-1 is drained from the stable base 2. At this time, the retractable flaps 2-3 on the base 2-2 return to their retracted state, which makes it easier to move and store the stable base 2.
[0026] Specifically, the inclined groove 2-2b transmission mechanism includes a convex shaft 2-1b located on the outside of the water tank 2-1 and an inclined groove 2-2b located on the inner wall of the base 2-2. The convex shaft 2-1b is engaged in the inclined groove 2-2b and can slide within it. When water is added to the water tank 2-1, it moves downward in a straight line due to gravity. The convex shaft 2-1b on the outside of the water tank 2-1 slides along the inclined groove 2-2b on the inner wall of the base 2-2. The inclined groove 2-2b follows a spiral or inclined trajectory, and the linear displacement of the convex shaft 2-1b is forcibly converted into the rotational motion of the water tank 2-1.
[0027] The base 2-2 has a take-up / de-take-up groove 2-2a on its side, and a rotating shaft 2-3a is provided at one end of the take-up / de-take-up flap. The take-up / de-take-up flap is rotatably connected to one end of the take-up / de-take-up groove 2-2a via the rotating shaft 2-3a. The rotating shaft 2-3a enables the rotatable connection of the take-up / de-take-up flap. When the take-up / de-take-up flap 2-3 is in the retracted state, it is completely retracted into the take-up / de-take-up groove 2-2a, as shown below. Figure 2 As shown.
[0028] The transmission connection mechanism includes a cantilever arm 2-3b mounted on the opening / closing flap and a follower rod 2-1c mounted at the bottom of the water tank 2-1. The cantilever arm 2-3b has a groove 2-3c, into which the follower rod 2-1c is inserted. When the water tank 2-1 rotates, the follower rod 2-1c at the bottom moves circumferentially with the water tank 2-1. The follower rod 2-1c inserted into the groove 2-3c of the cantilever arm 2-3b slides along the trajectory of the groove 2-3c, pushing the cantilever arm 2-3b to cause the opening / closing flap 2-3 to rotate in a fan shape around the pivot 2-3a, thus realizing the opening or closing of the opening / closing flap 2-3.
[0029] A sleeve 2-4 is provided on the water tank 2-1, and a locking screw 2-4a is connected to the sleeve 2-4.
[0030] In this embodiment, the water injection tank 2-1 has a cylindrical structure and the accommodating cavity is a cylindrical cavity.
[0031] In this embodiment, the elastic element is spring 2-5.
[0032] In this invention, the stable base 2 combines stability and ease of storage, greatly improving the usability.
[0033] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
