Description

Technical Field

[0001] This invention relates to the field of umbrella and household goods technology, specifically a beach parasol. Background Technology

[0002] During daily beach vacations, people need a place to shade themselves from the scorching sun, making beach umbrellas indispensable. Nowadays, beach umbrellas have become an essential item in beach resort areas. However, if the installation and securing method of a beach umbrella is inconvenient, it becomes impractical and significantly reduces travel comfort. Therefore, the design and application of beach umbrellas should prioritize ease of use and adaptability to changing scenarios, while also considering the user experience.

[0003] There are many ways to install and fix beach umbrellas. The base of existing beach umbrellas generally uses a water tank and a large metal plate as support points to install the umbrella body. The water tank and metal plate are large and heavy, making them extremely difficult to move and taking up a lot of space, which is inconvenient for most users. After the water tank is transported to the campsite, it is necessary to go to the beach to fill the water tank, which greatly reduces the user experience. After the metal plate is transported to the location, the surface of the beach is uneven, so the surface needs to be leveled before it can be placed stably. During use, the beach umbrella with the metal plate as the base is often affected by the sea wind, causing it to sway and even risk tipping over.

[0004] Based on the above problems, existing technologies have provided some solutions. For example, Ningbo Jiaxin Tourism Products Group Co., Ltd. invented a dual-purpose sun umbrella (application number: CN200710070366.6, publication date: 2008-01-09). This invention includes a column, a diagonal bar, a crossbar, an umbrella frame, a crank mechanism, and a movable locking mechanism on the column. The diagonal bar is hinged at both ends to the column and the crossbar, respectively. The top of the crossbar is hinged to the central umbrella rod of the umbrella frame. A sliding groove is provided on the crossbar, and a slider hinged to the top of the column is embedded in this groove, allowing the top of the column to slide relative to the crossbar along the groove. The crossbar can also rotate relative to the column about the top of the column. Although this sun umbrella allows for two different usage modes and is simple and labor-saving to operate, it does not adequately address the issue of convenient installation and fixing. It still uses a large metal plate as a support point for fixing, increasing the labor cost of transportation and wasting floor space.

[0005] In view of this, and to address the aforementioned shortcomings, this invention has developed a beach sunshade umbrella. Summary of the Invention

[0006] The technical problem that this invention aims to solve is that existing beach umbrellas cannot be conveniently fixed to a base, which increases labor intensity, occupies a portion of the shade area, and is inconvenient to change position and store once installed.

[0007] This invention provides the following technical solution: a beach parasol, comprising an umbrella canopy and a main pole. The umbrella canopy is mounted on the main pole, which also includes a telescopic mechanism and a pushing mechanism. The top surface of the main pole is fixedly installed at the center inside the umbrella canopy. The main pole is used to protect the various mechanisms. The diameter of the main pole is 30mm. The telescopic mechanism is installed at the bottom of the main pole. The telescopic mechanism transmits power to a rotating shaft by manually rotating the handle. The rotating shaft drives the drill bit to move axially downward. At the same time, rotating the shaft drives the support rod to rotate at a certain angle and insert it into the sand. The pushing mechanism is installed at the top of the main pole. The pushing mechanism transmits power to a rotating shaft by manually rotating the handle. The rotating shaft drives a conical frustum to move axially upward and pushes the umbrella frame connecting shaft to move upward to unfold the umbrella canopy.

[0008] The telescopic mechanism includes a rotating shaft, a threaded protrusion, internal and external threaded bushings, a ring, a connecting rod, a drill bit, and an extension assembly. The rotating shaft is coaxially rotatably mounted inside the main rod. The diameter of the rotating shaft is 16mm. A threaded protrusion with a diameter of 10mm, a pitch of 2.5mm, and a thread angle of 60° is provided at the bottom of the rotating shaft. The internal thread of the threaded bushing has a diameter of 12mm, a pitch of 2.5mm, and a thread angle of 60°, while the external thread has a diameter of 15mm, a pitch of 2.5mm, and a thread angle of 60°. The ring is mounted on top of the internal and external threaded bushings, and strip-shaped protrusions are formed around the ring. A connecting rod is installed at the bottom end of the threaded protrusion. The drill bit is made of high-speed steel and has… It features high hardness, high strength, high toughness, and high heat resistance. The cutting diameter is 24mm, the length is 100mm, the cone angle is 60°, the cutting edge angle is 118°, and the helix angle is 30°. The length of the connecting rod is equal to the length of the threaded protrusion. The drill bit is mounted at the bottom of the connecting rod, and its travel length is equal to the length of the threaded protrusion. The extension assembly is mounted on internal and external threaded bushings. The rotating shafts in the telescopic mechanism are all made of aluminum alloy. Aluminum alloy has a low density, typically weighing only about one-third of steel, thus its light weight significantly reduces the weight of the telescopic mechanism and transportation labor costs. Aluminum alloy also has high strength, good mechanical properties, and good corrosion resistance, making it perfectly suited to the operating environment of the telescopic mechanism.

[0009] The extension assembly includes a gear, a rotating rod, rotating teeth, a rotating rod, and a support rod. The gear is mounted on and meshes with the internal and external threaded sleeves. The gear has a module of 0.5, 10 teeth, a diameter of 5 mm, a tooth pitch of 2.5 mm, a common surface diameter of 7.5 mm, and a center distance of 10 mm. The rotating rod is mounted on the gear, and the rotating teeth mesh with the gear. A rotating rod is mounted on the rotating teeth. Both ends of the rotating rod and the rotating rod are mounted on the inner wall of the main rod. The support rod is mounted on the rotating rod, and the rotation angle of the support rod is between 90° and 180°.

[0010] The pushing mechanism includes a rotating shaft, a fixed thread, an internal threaded sleeve, a conical frustum, an umbrella frame connecting shaft, and a rotating assembly. The top of the rotating shaft is provided with a fixed thread, the fixed thread having a diameter of 10mm, a pitch of 2.5mm, and a thread angle of 60°. An internal threaded sleeve is installed on the fixed thread, and a conical frustum is installed on the internal threaded sleeve. Rectangular protrusions are provided around the internal threaded sleeve, and the distance between the outermost of the rectangular protrusions is less than the diameter of the cylinder. The top surface of the conical frustum is connected to the bottom surface of the umbrella frame connecting shaft, and the rotating assembly is installed at the bottom of the rotating shaft.

[0011] The rotating assembly includes a driving bevel gear, a fixed rod, a handle, and a driven bevel gear. A fixed rod is installed on one side of the driving bevel gear, and a handle is installed on the free end of the fixed rod. The driven bevel gears are respectively installed on the bottom of the rotating shaft and the top of the transmission shaft, and the driven bevel gear and the driving bevel gear mesh with each other. The distance between the upper and lower driven bevel gears is equal to the minimum diameter of the driving bevel gear. This is to ensure that the driving bevel gear can drive the driven bevel gear to rotate.

[0012] The top and bottom of the rotating shaft are provided with circular grooves, and cylinders are installed in the circular grooves on the top and bottom of the rotating shaft. A disc is provided in the middle of the cylinder to support the rotating shaft. The distance between the two discs is equal to the minimum diameter of the active bevel tooth. This is to ensure that the active bevel tooth can drive the driven bevel tooth to rotate.

[0013] A slider is installed on the umbrella frame connecting shaft, and the slider is vertically installed on the main pole. The sliding distance of the slider is the height of the umbrella canopy when it is fully open. This is to ensure that the umbrella canopy can be fully opened.

[0014] The umbrella frame is made of synthetic fiber material, which is lightweight, low in density, and has good flexibility, allowing it to be bent and rotate. It also has good strength and durability, is not easy to break, deform, or age, and will not corrode or rust. It can be used for a long time in humid or damp environments, and has advantages such as low cost and relatively economical price.

[0015] A rectangular through hole is provided at the upper 1 / 3 of the main rod. The length of the rectangular through hole is equal to the moving distance of the slider. The rectangular through hole is used to unfold the umbrella surface. A circular hole is provided in the middle of the main rod. An elongated groove is provided at the bottom of the main rod. The length of the elongated groove is equal to the length of the support rod.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention provides a telescopic mechanism on the main pole. Through the cooperation of the telescopic mechanism and the rotating component, when fixing the umbrella frame, the drill bit is inserted into the sand by rotating the handle, thereby fixing the umbrella frame. This allows for quick installation of the beach umbrella, reduces labor, and saves space.

[0018] 2. This invention provides an extension component on the telescopic mechanism. Through the cooperation between the telescopic mechanism and the extension component, the support rod on the extension component rotates when the umbrella frame is fixed, thereby providing secondary fixation to the umbrella frame. This enhances the stability of the beach umbrella and allows for quick installation while reducing labor costs.

[0019] 3. This invention provides a pushing mechanism on the main pole. Through the cooperation of the pushing mechanism and the rotating mechanism, the umbrella frame is fixed by the telescopic mechanism while the umbrella canopy is unfolded by the pushing mechanism, thus enabling the beach parasol to be installed quickly.

Detailed Implementation

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 8As shown, a beach umbrella includes an umbrella canopy 1 and a main pole 2. The umbrella canopy 1 is mounted on the main pole 2. The main pole 2 is used to protect various mechanisms. Generally, the main pole 2, as the largest supporting component, needs to consider factors such as weight, strength, corrosion resistance, and handling force. Ultimately, it is made of aluminum alloy. It also includes a telescopic mechanism 3 and a pushing mechanism 4. The telescopic mechanism 3 is installed at the bottom of the main pole 2. The telescopic mechanism 3 transmits power to the rotating shaft 31 by manually rotating the handle 463. The rotating shaft 31 drives the drill bit 36 ​​to move axially downward. At the same time, rotating the rotating shaft 41 drives the support rod 375 to rotate at a certain angle and insert it into the sand. The pushing mechanism 4 is installed at the top of the main pole 2. The pushing mechanism 4 transmits power to the rotating shaft 41 by manually rotating the handle 463. The rotating shaft 41 drives the conical frustum 44 to move axially upward and pushes the umbrella frame connecting shaft 45 upward to unfold the umbrella canopy 1.

[0032] During operation, the telescopic mechanism 3 and the pushing mechanism 4 are rotated simultaneously by manual rotation, burying the umbrella body into the ground to a certain depth through the telescopic mechanism 3. At the same time, the pushing mechanism 4 slowly pushes the umbrella frame to the position above the main pole 2 to open the umbrella surface 1. After the telescopic mechanism 3 extends to a certain length, it is engaged with the extension component 37, causing the extension component 37 to unfold in all directions as the telescopic mechanism 3 extends, thereby fixing and unfolding the entire umbrella frame on the beach.

[0033] This method allows the entire umbrella body to operate by rotating the rotating component 46. While the bottom of the umbrella body is fixed, the umbrella canopy 1 can be slowly opened, providing a secondary reinforcement support for the umbrella body. Existing inventions require the base to be installed slowly before the umbrella canopy 1 can be opened, which is time-consuming and labor-intensive. Compared with existing inventions, this invention can not only fix the base in one step, but also allow the umbrella canopy 1 to be opened simultaneously to form two reinforcement installations, greatly reducing the installation time and saving a lot of effort.

[0034] like Figure 5As shown, the telescopic mechanism 3 includes a rotating shaft 31, a threaded protrusion 32, internal and external threaded bushings 33, a ring 34, a connecting rod 35, a drill bit 36, and an extension assembly 37. The rotating shaft 31 is coaxially rotatably mounted inside the main rod 2. The bottom of the rotating shaft 31 is provided with a threaded protrusion 32, which has a diameter of 10 mm, a pitch of 2.5 mm, and a thread angle of 60°. The internal and external threaded bushings 33 are mounted on the surface of the threaded protrusion 32, and the ring 34 is mounted on... The annular ring 34, mounted on the top of the internal and external threaded bushing 33, has strip-shaped protrusions 38 around its perimeter. To save effort and ensure perfect meshing between the threaded protrusions 32 and the internal and external threaded bushing 33, the selected parameters are: internal thread diameter of 12mm, pitch of 2.5mm, and thread angle of 60° for the internal thread of the bushing 33; external thread diameter of 15mm, pitch of 2.5mm, and thread angle of 60°. A connecting rod 35 is mounted at the bottom of the threaded protrusion 32, and the length of the connecting rod 35 is equal to the thread diameter. The length of the threaded protrusion 32 is specified. The drill bit 36 ​​is installed at the bottom of the connecting rod 35. The moving length of the drill bit 36 ​​is equal to the length of the threaded protrusion 32. The extension component 37 is installed on the internal and external threaded bushing 33. The drill bit 36 ​​is made of high-speed steel, which has high hardness, high strength, high toughness and high heat resistance. The cutting diameter is 24mm, the length is 100mm, the cone angle is 60°, the cutting edge angle is 118° and the helix angle is 30°. The large diameter and deep depth allow the drill bit 36 ​​to be more stable as a base rooted in the sand. The rotating shaft 31 in the telescopic mechanism 3 is made of aluminum alloy. Aluminum alloy has a low density and usually weighs only about one-third of steel. Therefore, it is lightweight, which can greatly reduce the weight of the telescopic mechanism 3 and greatly reduce the labor cost of transportation. Aluminum alloy also has high strength and good mechanical properties, as well as good corrosion resistance, which can perfectly adapt to the operating environment of the telescopic mechanism 3.

[0035] During operation, the rotating shaft 31 of the telescopic mechanism 3 rotates, causing the threaded protrusion 32 to rotate. The threaded protrusion 32 rotates inside the inner and outer threaded bushings 33, causing the ring 34 and the inner and outer threaded bushings 33 to drive the connecting rod 35 to move axially. At the same time, it drives the drill bit 36 ​​to move downward. The drill bit 36 ​​will vertically enter the sand. Existing sun umbrellas use water tanks and metal plates as fixed bases, which take up space and are difficult to transport. The telescopic mechanism 3 of the present invention can perfectly solve the problems of the prior art, reduce the footprint, and enhance stability, so that the beach sun umbrella can cope with more emergencies.

[0036] like Figure 7As shown, the extension component 37 includes a gear 371, a rotating rod 372, a rotating tooth 373, a rotating rod 374, and a support rod 375. The gear 371 is mounted on an internal and external threaded sleeve and meshes with it. The gear 371 has a module of 0.5, 10 teeth, a diameter of 5 mm, a tooth pitch of 2.5 mm, a common surface diameter of 7.5 mm, and a center distance of 10 mm. These parameters are chosen to make the gear 371 fit more efficiently and to allow for sufficient space. The rotating rod 372 is mounted on the gear 371. The rotating tooth 373 meshes with the gear 371. The rotating rod 374 is mounted on the rotating tooth 373. The two ends of the rotating rod 374 and the rotating rod 372 are mounted on the inner wall of the main rod 2. The support rod 375 is mounted on the rotating rod 374. The rotation angle of the support rod 375 is between 90° and 180°.

[0037] During operation, the gear 371 on the extension assembly 37 rotates, which in turn drives the rotating gear 373 to rotate. The rotating gear 373 drives the support rod 375 to rotate, thereby achieving an outward flipping motion. When the support rod 375 rotates 90 degrees, it will contact the horizontal surface of the beach and remain horizontal. When the support rod 375 rotates more than 90 degrees, it can be directly inserted into the sand, thereby strengthening the fixation of the umbrella frame.

[0038] This method allows the telescopic mechanism 3 to move while simultaneously driving the extension component 37 to form a secondary support reinforcement on the ground. Existing inventions all use a classic base as the support base without a secondary reinforcement support. This mechanism can perfectly solve this problem. While the telescopic mechanism 3 acts as the base, the support rod 375 of the telescopic mechanism 3 is attached to the ground to form a secondary reinforcement support, which can make the beach umbrella withstand greater sea winds and have better stability.

[0039] like Figure 4 As shown, the pushing mechanism 4 includes a rotating shaft 41, a fixed thread 42, an internal threaded sleeve 43, a conical frustum 44, an umbrella frame connecting shaft 45, and a rotating assembly 46. The top of the rotating shaft 41 is provided with a fixed thread 42, which has a diameter of 10 mm, a pitch of 2.5 mm, and a thread angle of 60°. An internal threaded sleeve 43 is installed on the fixed thread 42, which has an internal thread diameter of 17 mm, a pitch of 2.5 mm, and a thread angle of 60°. A conical frustum 44 is installed on the internal threaded sleeve 43, and rectangular protrusions 47 are provided around the internal threaded sleeve 43. The distance between the outermost rectangular protrusions 47 is less than the diameter of the cylinder 481. The top surface of the conical frustum 44 is connected to the bottom surface of the umbrella frame connecting shaft 45. The rotating assembly 46 is installed at the bottom of the rotating shaft 41.

[0040] During operation, the rotating shaft 41 of the pushing mechanism 4 rotates, causing the fixed thread 42 to rotate and the internal thread sleeve 43 to rotate as well. This causes the conical frustum 44 to move upward and pushes one end of the umbrella frame connecting shaft 45 upward, thereby unfolding the umbrella surface 1. In this way, the umbrella frame connecting shaft 45 can be fixed to the limit position by the rising of the internal thread sleeve 43, which can achieve a firm installation of the umbrella frame. Existing sun umbrellas generally fix the umbrella frame connecting shaft 45 with buckles. In the event of strong winds, the umbrella frame connecting shaft 45 may break free from the fixation, causing the umbrella surface 1 to suddenly contract. This pushing mechanism 4 solves this problem perfectly by pushing and pushing, greatly increasing the stability of the umbrella surface 1.

[0041] like Figure 6 As shown, the rotating assembly 46 includes an active bevel gear 461, a fixed rod 462, a handle 463, and a driven bevel gear 464. The fixed rod 462 is installed on one side of the active bevel gear 461, and the handle 463 is installed on the free end of the fixed rod 462. The driven bevel gear 464 is respectively installed on the bottom of the rotating shaft 41 and the top of the transmission shaft, and the driven bevel gear 464 and the active bevel gear 461 mesh with each other. The distance between the upper and lower driven bevel gears 464 is equal to the minimum diameter of the active bevel gear 461.

[0042] During operation, the user rotates the handle 463 by gripping it, which in turn drives the fixed rod 462 to rotate. The fixed rod 462 then drives the active bevel gear 461 to rotate, which in turn drives the driven bevel gear 464 to rotate, thereby driving the upper and lower rotating shafts 41 and the rotating shaft 31 to rotate, thus realizing the unfolding and fixing of the umbrella frame.

[0043] This method uses the power source provided by the handle 463 to drive the rotating shaft 31 inside the main pole 2 to rotate, thereby realizing the opening and closing of the umbrella, as well as the fixing and secondary reinforcement of the umbrella base. This solves the problem of the existing sun umbrellas where the base must be installed first and then the canopy 1 must be opened, greatly shortening the installation time and saving a lot of disassembly steps.

[0044] like Figure 6 As shown, a circular groove 48 is provided at the top of the rotating shaft 41 and the bottom of the rotating shaft 31. A cylinder 481 is installed in the circular groove 48 at the top of the rotating shaft 41 and the bottom of the rotating shaft 31. A disc 482 is provided in the middle of the cylinder 481. The distance between the two discs 482 is equal to the minimum diameter of the active bevel tooth 461.

[0045] During operation, the drive gear 371 drives the driven gear 371 to rotate, which in turn drives the rotating shaft 41 and the rotating shaft 31 to rotate. The cylinder 481 will rotate in the circular groove 48, and the disc 482 will rotate below the rotating shaft 41 and support the rotating shaft 41.

[0046] like Figure 1 As shown, a slider 451 is installed on the umbrella frame connecting shaft 45, and the slider 451 is vertically installed on the main pole 2. The sliding distance of the slider 451 is the height of the umbrella surface 1 when it is open.

[0047] During operation, when the umbrella canopy 1 is unfolded, the conical frustum 44 on the pushing mechanism 4 pushes the slider 451 on the umbrella frame to slide upward on the main rod 2, thereby pushing the umbrella frame connecting shaft 45 to move upward and realizing the unfolding of the umbrella canopy 1.

[0048] like Figure 8 As shown, a rectangular through hole 21 is provided at the upper 1 / 3 of the main rod 2. The length of the rectangular through hole 21 is equal to the moving distance of the slider 451. A circular hole 22 is provided in the middle of the main rod 2. An elongated groove 23 is provided at the bottom of the main rod 2. The length of the elongated groove 23 is equal to the length of the support rod 375.

[0049] Overall working process: When fixing the umbrella frame on the beach, the operator manually rotates the handle 463, which in turn drives the fixing rod 462 to rotate. The fixing rod 462 drives the driving bevel gear 461 to rotate, which in turn drives the driven bevel gear 464 to rotate. When the driving gear 371 drives the driven gear 371 to rotate, it also drives the rotating shaft 41 and the rotating shaft 31 to rotate. The cylinder 481 will rotate within the circular groove 48, and the disc 482 will rotate below the rotating shaft 41 and support the rotating shaft 41. The rotation of the rotating shaft 31 drives the threaded protrusion 32 to rotate. The threaded protrusion 32 will rotate inside the inner and outer threaded bushing 33. The rotation causes the ring 34 and the internal and external threaded bushing 33 to move the connecting rod 35 axially, while simultaneously moving the drill bit 36 ​​downwards. The drill bit 36 ​​will vertically enter the sand. When the rotating shaft 31 drives the internal and external threaded bushing 33 to rotate, it also drives the gear 371 to rotate. The gear 371 drives the rotating tooth 373 to rotate, and the rotating tooth 373 drives the support rod 375 to rotate, thereby achieving an outward flipping motion. When the support rod 375 rotates 90 degrees, the support rod 375 will contact the horizontal surface of the sand and remain horizontal. When the support rod 375 rotates more than 90 degrees, the support rod 375 can be directly inserted into the sand.

[0050] At the same time, the driven bevel gear 464 drives the rotating shaft 41 to rotate, which in turn drives the fixed thread 42 to rotate and causes the internal thread sleeve 43 to rotate as well. This causes the conical frustum 44 to move upward and pushes one end of the umbrella frame connecting shaft 45 to move upward. When the umbrella surface 1 is unfolded, the conical frustum 44 pushes the slider 451 on the umbrella frame to slide upward on the main rod 2. Thus, the slider 451 pushes the umbrella frame connecting shaft 45 to move upward and realizes the unfolding of the umbrella surface 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
