Description

Technical Field

[0001] This utility model belongs to the field of sunshade technology, specifically relating to a new type of sunshade with an opening and closing structure. Background Technology

[0002] Outdoor sun umbrellas are a common outdoor accessory used in outdoor activities, typically for sheltering people from wind and rain. Outdoor sun umbrellas generally include types such as center-pole umbrellas, Roman umbrellas, and banana umbrellas. Center-pole umbrellas usually have an opening and closing crank mechanism on the umbrella poles to control the opening and closing of the umbrella frame via the parachute cords. As disclosed in CN220477073U, a stabilizing crank mechanism for opening and closing sun umbrellas includes a crank shaft and a crank handle for driving the crank shaft to rotate. The crank shaft passes through a locking bracket, and a ratchet assembly is fitted onto the locking bracket. The ratchet assembly includes a ratchet body and a pawl for unidirectional locking with the ratchet body teeth. The pawl includes a pawl body and pawl teeth located at the end of the pawl body. The pawl teeth mesh with the ratchet teeth in the ratchet body. The lower part of the pawl body is hinged to the locking bracket via a hinge shaft. A pawl support is provided on the locking bracket, which meshes with the lower part of the pawl body. This utility model optimizes the design of the pawl support, so that the pawl has a bottom support action after assembly, improving the locking effect of the pawl on the ratchet and avoiding the problem of slippage or tooth disengagement between the pawl and the ratchet teeth in the ratchet body, thus improving the meshing stability of the pawl and the ratchet body.

[0003] However, the opening and closing crank mechanism has many parts, and the internal components are closely related. After a period of use, it is prone to aging and damage, which will affect the normal opening and closing of the sunshade. In addition, the production cost of the opening and closing crank mechanism is relatively high. Utility Model Content

[0004] To address the aforementioned issues, this utility model aims to provide a novel sun umbrella with a simple opening and closing structure. The umbrella can be opened by manually pulling the cords to tighten them, and a cord-locking mechanism can lock the cords after they have been rolled up, thus locking the umbrella in place. To unlock, simply release the cord-locking mechanism to close the umbrella. An optimized multi-stage pulley mechanism reduces the force required when pulling the cords, facilitating operation. The absence of a crank handle reduces overall production and maintenance costs.

[0005] The technical problem solved by this utility model can be achieved by the following technical solution: A new type of sun umbrella with an opening and closing structure, including an umbrella column, an umbrella frame, an opening and closing mechanism, and umbrella cords. The umbrella frame includes an upper umbrella plate and a lower umbrella plate. The opening and closing mechanism includes a first pulley mechanism located in the upper umbrella plate, a second pulley mechanism located in the lower umbrella plate, and a third pulley mechanism located between the first pulley mechanism and the second pulley mechanism. The umbrella cords are wound around the first pulley mechanism, the second pulley mechanism, and the third pulley mechanism. One end of the umbrella cords is fixedly installed with the lower umbrella plate, and the other end is engaged with a cord locking mechanism in the middle of the umbrella column.

[0006] The first pulley mechanism includes two first pulley units, each of which is a fixed pulley structure, and is respectively located on the left and right sides inside the upper umbrella plate.

[0007] The second pulley mechanism includes a second pulley unit, which adopts a movable pulley structure.

[0008] The third pulley mechanism is located inside the umbrella column between the first and second pulley mechanisms. The third pulley mechanism includes two third pulley units, which are fixed pulley structures and are respectively set on the left and right sides inside the umbrella column.

[0009] The rope locking mechanism includes a locking sleeve, which is fitted with a locking knob so that the locking knob can move in and out of the locking sleeve along the axial direction of the locking sleeve. The other end of the paracord is wound around the shaft of the locking knob. By moving the locking knob axially, the paracord is locked or released between the locking sleeve and the locking knob.

[0010] The umbrella column is also equipped with a limiting component, which is located between the lower umbrella disc and the third pulley mechanism. When the lower umbrella disc moves upward along the umbrella column to the limiting component, the lower umbrella disc and the limiting component form a stop and limit.

[0011] The lower umbrella tray is also equipped with a safety pin, which includes a pin body and a connector. The umbrella column is provided with a pin hole. The pin hole is located at the bottom of the lower umbrella tray when the umbrella frame is fully opened. The pin body passes through the pin hole. When the umbrella frame is closed, the bottom of the lower umbrella tray and the pin body form a stop and limit.

[0012] The lower umbrella tray is also equipped with a rope guide section, which includes a rope guide groove for holding the umbrella rope.

[0013] The umbrella frame also includes several umbrella rib assemblies, which are hinged to the upper and lower umbrella discs, and the umbrella fabric is provided on the umbrella rib assemblies.

[0014] Compared with the prior art, this utility model has the following advantages: The opening and closing umbrella structure of this utility model is relatively simple. The outdoor umbrella can be opened by manually pulling the umbrella cord to tighten it. The cord locking mechanism can lock the umbrella cord that has been rolled up after the exhibition, thus locking the outdoor umbrella when it is open. To unlock, simply release the cord locking mechanism to close the umbrella. The multi-stage pulley mechanism is optimized to reduce the force required when the user pulls the umbrella cord, making it easier to operate. There is no need for a matching crank handle structure, which reduces the overall production and maintenance costs. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Combined with appendix Figures 1 to 3As shown, this embodiment discloses a novel opening and closing umbrella structure, including an umbrella column 1, an umbrella frame 2, an opening and closing umbrella mechanism, and umbrella cords 3. The umbrella frame 2 includes an upper umbrella plate 21 and a lower umbrella plate 22. The opening and closing umbrella mechanism includes a first pulley mechanism 4 located in the upper umbrella plate 21, a second pulley mechanism 5 located in the lower umbrella plate 22, and a third pulley mechanism 6 located between the first pulley mechanism 4 and the second pulley mechanism 5. The umbrella cords 3 are wound around the first pulley mechanism 4, the second pulley mechanism 5, and the third pulley mechanism 6. One end of the umbrella cords 3 is fixedly installed with the lower umbrella plate 22, and the other end is engaged with the cord locking mechanism in the middle of the umbrella column 1.

[0020] In this embodiment, the first pulley mechanism 4 includes two first pulley units 41, which are fixed pulley structures and are respectively arranged on the left and right sides inside the upper umbrella tray 21; the second pulley mechanism 5 includes a second pulley unit 51, which is a movable pulley structure; the third pulley mechanism 6 is located inside the umbrella column 1 between the first pulley mechanism 4 and the second pulley mechanism 5, and includes two third pulley units 61, which are fixed pulley structures and are respectively arranged on the left and right sides inside the umbrella column 1 to prevent the third pulley units 61 from colliding with the other components of the umbrella frame 2.

[0021] In this embodiment, in conjunction with the above installation structure, the upper umbrella plate 21, the lower umbrella plate 22 and the umbrella column 1 are respectively provided with cavities for installing the first pulley mechanism 4, the second pulley mechanism 5 and the third pulley mechanism 6.

[0022] In summary, the cord locking mechanism includes a locking sleeve 11, which is fitted with a locking knob 12, allowing the locking knob 12 to move in and out of the locking sleeve 11 along its axial direction. The other end of the paracord 3 is wound around the shaft of the locking knob 12. The axial movement of the locking knob 12 forms or releases a limiting lock between the paracord 3 and the locking sleeve 11 and the locking knob 12. Preferably, in this embodiment, the locking sleeve 11 and the shaft of the locking knob 12 are connected by a thread. In other embodiments, other commonly used connection structures in the prior art can also be used. The end of the paracord 3 is wound around the shaft of the locking knob 12. When the locking knob 12 is rotated to move towards the locking sleeve 11, the locking knob 12 compresses the wound paracord 3, forming a limiting lock; conversely, when the locking knob 12 is rotated in the opposite direction, the limiting lock between the locking knob 12 and the paracord 3 is released.

[0023] In conjunction with the above installation structure, in this embodiment, the overall connection structure of the parachute rope 3 is as follows: one end of the parachute rope 3 is wound around the shaft of the locking knob 12 several times, then extends upward from bottom to top through the lower umbrella plate 22, continues to extend upward to the upper umbrella plate 21, winds around the first pulley mechanism 4, then extends downward to the lower umbrella plate 22, winds around the second pulley mechanism 5, then extends upward and passes through the umbrella column 1 from the side, passes through the third pulley mechanism 6, and finally extends downward to the lower umbrella plate 22, with the end fixedly connected to the lower umbrella plate 22.

[0024] Based on the above installation structure, when the locking knob 12 is rotated to release the locking limit of the paracord 3, the number of turns of the paracord 3 around the shaft of the locking knob 12 can be increased. At this time, the lower paracord plate 22 moves upward along the paracord column 1, thus realizing the unfolding of the paracord frame 2. Conversely, the number of turns of the paracord 3 around the shaft of the locking knob 12 is reduced. At this time, the lower paracord plate 22 moves downward along the paracord column 1, thus realizing the folding of the paracord frame 2. After confirming the unfolded state of the paracord frame 2, rotating the locking knob 12 to lock the paracord 3 will fix the state of the paracord frame 2.

[0025] In conjunction with the above, a limiting member 13 is also provided on the umbrella column 1. The limiting member 13 is located between the lower umbrella disc 22 and the third pulley mechanism 6. When the lower umbrella disc 22 moves upward along the umbrella column 1 to the limiting member 13, the lower umbrella disc 22 and the limiting member 13 form a contact limit. In this embodiment, the limiting member 13 is a convex structure on the side of the umbrella column 1 to prevent the lower umbrella disc 22 from moving upward excessively.

[0026] In conjunction with the above, the lower umbrella tray 22 is also provided with a safety pin part 221. The safety pin part 221 includes a pin body 2211 and a connector 2212. In this embodiment, the connector 2212 adopts a chain structure to connect the lower umbrella tray 22 and the pin body 2211. The umbrella column 1 is provided with a pin hole 14, which is located at the lower part of the lower umbrella tray 22 when the umbrella frame 2 is fully opened. The pin body 2211 passes through the pin hole 14. When the umbrella frame 2 is closed, the bottom of the lower umbrella tray 22 and the pin body 2211 form a stop and limit. Specifically, under normal circumstances, when the user operates the parasol rope 3 and the locking knob 12 to fully open the umbrella frame 2, the pin body 2211 is inserted into the pin hole 14. When the user is ready to close the umbrella frame 2 after use, it can prevent the lower umbrella tray 22 from suddenly falling due to the sudden release of the limit lock by the locking knob 12, which could cause a safety accident.

[0027] In conjunction with the above, the lower parachute tray 22 is also provided with a rope guide section 222, which includes a rope guide groove for placing the parachute rope 3 and preventing the parachute rope 3 from shifting or getting tangled on other parts during the journey.

[0028] In conjunction with the above, the umbrella frame 2 also includes several umbrella rib assemblies, which are hinged to the upper umbrella plate 21 and the lower umbrella plate 22. The umbrella rib assemblies are covered with umbrella fabric. The umbrella rib assemblies include long umbrella ribs and short umbrella ribs. The hinge method and structure of the umbrella rib assemblies to the upper umbrella plate 21 and the lower umbrella plate 22 adopt existing technologies such as hinged connection through hinge seats on the umbrella plate.

[0029] This utility model features a simple opening and closing umbrella structure. The umbrella can be opened by manually pulling the cords to tighten them, and the cord locking mechanism can lock the cords after the umbrella is rolled up, thus locking the umbrella in place. To unlock, simply release the cord locking mechanism to close the umbrella. The optimized multi-stage pulley mechanism reduces the force required for the user to pull the cords, making it easier to operate. The absence of a crank handle reduces overall production and maintenance costs.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
