Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor products, and particularly relates to a double-bend tube sliding sleeve hanging umbrella. Background Art

[0002] Outdoor umbrellas, also known as parasols, can be divided into side column umbrellas, Roman umbrellas, banana umbrellas, etc. according to their shapes. They are usually single-sided umbrellas. As a more unique type of outdoor parasol, the curved arm hanging umbrella has a good market and good appearance, which is popular among many people.

[0003] In the prior art, a curved arm hanging umbrella primarily consists of an upper curved tube, a lower curved tube, an umbrella canopy, and a base. The assembly of the upper and lower curved tubes can be categorized into two types: the first is a plug-in telescopic structure, where when the upper curved tube is extended outward to its limit, the umbrella frame is opened by rotating a pulley. The second is a side-by-side telescopic structure, where the upper and lower curved tubes are arranged side by side and connected by an armrest shell assembly, pushing the upper curved tube outward or inward.

[0004] For example, the announcement number CN221241903U discloses a pressure-rod opening and closing type curved tube column outdoor parasol, including an umbrella column and an umbrella frame, the umbrella frame including an oblique rod group hinged on the upper umbrella plate and the lower umbrella plate, the umbrella column is a curved tube column, which is externally placed on one side of the umbrella frame, and a pressure rod mechanism is provided on the curved tube column to control the opening and closing of the umbrella frame, the pressure rod mechanism includes a sliding sleeve which is sleeved on the upper part of the curved tube column and moves up and down along the curved tube column, a handle assembly hinged on the lower part of the curved tube column, and a pull rod arranged between the sliding sleeve and the handle assembly; the oblique rod group includes a first oblique rod group and a second oblique rod group which are hingedly matched, one end of the first oblique rod group is hinged to the upper umbrella plate, and the other end is hinged to the sliding sleeve; one end of the second oblique rod group is hinged to the lower umbrella plate, and the other end is hinged to the top seat provided on the top of the umbrella column; the middle part of the handle assembly is hingedly matched with the umbrella column.

[0005] Publication number CN201019107Y discloses a curved-arm umbrella. It primarily consists of a vertical tube, an upper curved tube, a lower curved tube, and an umbrella frame. The bottom end of the lower curved tube is connected to the top end of the vertical tube. The upper and lower curved tubes have the same curvature and can slide relative to each other. A hand-held telescopic positioning mechanism is provided at the connection between the upper and lower curved tubes. The top end of the vertical tube and the bottom end of the lower curved tube are connected in a horizontally rotating manner, while the top end of the upper curved tube and the upper plate of the umbrella frame are connected in a pitching and rotating manner.

[0006] The first patent mentioned above suffers from the difficulty in adjusting the umbrella stand's orientation after it's unfolded, making it difficult to adapt to different customer needs. In the second patent, the upper and lower curved tubes are arranged side by side, occupying a larger space during transportation, which will increase the transportation costs of the upper and lower curved tubes. Utility Model Content

[0007] In order to make up for the deficiencies of the prior art, the utility model provides a double-bend tube sliding sleeve hanging umbrella to solve the technical problem that the storage of the upper and lower bend tubes and the adjustment of the umbrella surface are difficult to meet at the same time.

[0008] In order to achieve the above purpose, the specific technical solutions of the present utility model are as follows:

[0009] A double-bend tube sliding sleeve hanging umbrella includes a bend tube base, a lower bend tube, an upper bend tube, an umbrella frame body, and a handrail assembly. The lower bend tube is fixed to the bend tube base. The upper bend tube is slidably connected to the lower bend tube via a handrail shell assembly.

[0010] The inner side of the lower curved tube is provided with a mounting groove which matches the upper curved tube. The mounting groove forms a semi-covering structure for the upper curved tube. The umbrella stand body is mounted on the end of the upper curved tube through the umbrella stand base.

[0011] The armrest assembly includes an armrest shell, a winding reel assembly, and a locking structure mounted in conjunction with the armrest shell. The armrest shell is slidably connected to the lower curved tube. The locking structure is used to lock the armrest shell and the lower curved tube in position. The winding reel assembly is used to control the expansion and contraction of the umbrella frame. When the umbrella frame is expanded, it is always perpendicular to the end of the upper curved tube.

[0012] Furthermore, the armrest shell body includes a first shell and a second shell. The first shell and the second shell are combined and sleeved on the lower bend tube. The armrest shell body is provided with a winding wheel mounting cavity and a locking mounting cavity. The winding wheel assembly is disposed in the winding wheel mounting cavity. The locking structure is disposed in the locking mounting cavity.

[0013] Furthermore, the locking structure includes a control member and a locking assembly. The locking assembly is slidably connected to the armrest shell body and can be moved toward the lower bend tube by the control member. When the locking assembly is in contact with the lower bend tube, the position between the armrest shell body and the lower bend tube is locked.

[0014] Furthermore, the locking assembly includes a slider and a pressure block. The control element is a locking trigger. The pressure block is fixed to the slider. The locking trigger is rotatably connected to the mounting base. When the locking trigger is rotated clockwise, it pushes the slider toward the lower elbow. When the locking trigger is rotated counterclockwise, the end of the locking trigger moves away from the slider, allowing the slider to slide naturally under the action of gravity.

[0015] Furthermore, the locking trigger comprises an inner locking portion and an outer grip portion. The user can grip the locking trigger's grip portion. The locking portion comprises a raised section at the end and an outer unlocking section. When the raised section abuts the slider, the position between the armrest housing and the lower bend is locked. When the unlocking section abuts the slider, the position between the armrest housing and the lower bend is unlocked.

[0016] Furthermore, the lower curved tube is a semi-elliptical structure, and the locking portion is an elliptical structure.

[0017] Furthermore, the reel assembly includes a reel, a crank shaft, and a torsion spring that are sequentially interlocked. The crank shaft is rotatably connected to the armrest housing, and a crank handle is inserted at its outer end. A cord is wound around the reel, and the outer end of the cord is connected to the umbrella frame body.

[0018] Furthermore, the top end of the umbrella frame body is rotatably connected to the umbrella frame base. The umbrella frame base is provided with a limiting edge corresponding to the top end of the umbrella frame body.

[0019] Furthermore, pulleys are provided on both side edges of the bayonet holes of the first shell and the second shell that cooperate with the lower bend pipe.

[0020] Furthermore, an upper bushing and a lower bushing are provided on the lower bend pipe at intervals. A first slot and a second slot are provided on opposite sides of the first shell and the second shell to match the upper bushing and the lower bushing. The upper bushing and the lower bushing are embedded in the first slot and the second slot.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] The semi-enclosed structure between the lower and upper curved tubes in this utility model significantly reduces the storage space for the lower and upper curved tubes. Furthermore, the position between the expanded umbrella frame body and the upper curved tube is defined, allowing the umbrella frame body to expand and contract with the upper curved tube when expanded, thus adjusting the angle of the umbrella surface on the umbrella frame body.

DETAILED DESCRIPTION

[0031] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] like Figure 1 and 2 As shown, a double-bend tube sliding sleeve hanging umbrella includes a bend tube base 100, a lower bend tube 200, an upper bend tube 300, an umbrella frame base 400, an umbrella frame body 500, and an armrest assembly 600. The lower bend tube 200 is fixed to the bend tube base 100 and has a semi-elliptical structure. A mounting groove is provided on the inner side surface to match the upper bend tube 300. The upper bend tube 300 is slidably connected to the mounting groove via the armrest shell assembly, and the mounting groove forms a semi-enclosed structure for the upper bend tube 300. Under the control of the armrest shell assembly, the upper bend tube 300 can slide inward or outward along the curvature of the lower bend tube 200 and can be locked at any position. The umbrella frame body 500 is mounted at the end of the upper bend tube 300 via the umbrella frame base 400. The upper bend tube 300 can be adjusted by telescoping to achieve angle adjustment of the umbrella surface in the umbrella frame body 500.

[0034] like Figure 1-3As shown, the armrest assembly 600 includes an armrest shell body 610, a winding wheel set 620, and a locking structure 630 installed in conjunction with the armrest shell body 610. The inner end of the upper bend tube 300 is rotatably connected to the armrest shell body 610. The armrest shell body 610 includes a first shell 611 and a second shell 612. The first shell 611 and the second shell 612 are combined and sleeved on the lower bend tube 200, so that the armrest shell body 610 can slide in and out along the arc direction of the lower bend tube 200. The armrest shell body 610 is provided with a winding wheel 621 installation cavity and a locking installation cavity. The winding wheel set 620 is arranged in the winding wheel 621 installation cavity for controlling the expansion or folding of the umbrella stand body 500. The locking structure 630 is arranged in the locking installation cavity, which can realize the armrest shell body 610 sliding to any position and locking.

[0035] Furthermore, a supporting cladding in a shell structure is provided at the end of the lower bend pipe 200. The outer end of the upper bend pipe 300 passes through the supporting cladding and is supported by the supporting cladding.

[0036] Specific structure such as Figure 2-5 As shown, the locking structure 630 includes a mounting seat 631, a control member 632, and a locking assembly. The mounting seat 631 is fixed within the locking mounting cavity, and a sliding groove that cooperates with the locking assembly is provided on the side close to the lower bend tube 200. The locking assembly is slidably connected within the sliding groove and can move toward the side of the lower bend tube 200 through the push of the control member 632. The armrest shell body 610 is locked through the static friction between the locking assembly and the lower bend tube 200. When the control member 632 releases the pressure applied to the locking assembly, the static friction between the locking assembly and the lower bend tube 200 is weakened, allowing the armrest shell body 610 to slide on the lower bend tube 200.

[0037] Among them, the locking assembly includes a slider 633 and a clamping block 634. The control member 632 adopts a locking trigger. The clamping block 634 is fixed to the slider 633 by a screw. The locking trigger is rotatably connected to the mounting seat 631. When the user bends the locking trigger downward, the slider 633 will be pushed to move toward the side of the lower bend tube 200, so that the clamping block 634 is close to the lower bend tube 200, thereby achieving the locking of the armrest shell body 610 relative to the lower bend tube 200. When the user bends the locking trigger upward, the pressure applied to the slider 633 will be released, and the slider 633 will naturally slide down under the action of gravity, and the clamping block 634 will move away from the lower bend tube 200, thereby achieving the unlocking of the armrest shell body 610 relative to the lower bend tube 200.

[0038] In this embodiment, the locking trigger is composed of an inner locking portion and an outer grip portion. The user can grasp the grip portion of the locking trigger and twist it upward or downward, thereby driving the locking portion to rotate. The locking portion is an elliptical structure, consisting of a raised section 6321 at the end and an outer unlocking section 6322. During rotation, the locking portion has two extreme positions: a locked extreme position and an unlocked extreme position. When the locking portion is in the locked extreme position, the raised section 6321 on the locking portion abuts against the slider 633. The line connecting the end of the raised section 6321 to the rotation center of the locking trigger is parallel to the sliding direction of the slider 633. This balances the action and reaction forces between the slider 633 and the locking trigger, preventing the locking trigger from rotating and causing the armrest shell body 610 to automatically unlock. When the locking portion is in the locked extreme position, the unlocking section 6322 on the locking portion abuts against the slider 633.

[0039] like Figure 5 As shown, the winding wheel assembly 620 includes a winding wheel 621, a crank shaft 622 and a torsion spring 623 that are serially connected in sequence. Among them, a crank handle is detachably provided on the large outer end of the crank shaft 622, which is used to drive the crank shaft 622 to rotate, and then drive the winding wheel 621 set on the crank shaft 622 to rotate. A rope is wound around the winding wheel 621. The outer end of the rope is connected to the umbrella frame body 500. The torsion spring 623 adopts a torsion spring 623 that can prevent slipping in both directions, and is used to lock the crank shaft 622 after it rotates any number of circles. During use, when the winding wheel 621 is driven by the crank shaft 622 to reel in the rope, it will pull the upper umbrella plate and the lower umbrella plate in the umbrella frame body 500 closer to each other, and the umbrella frame body 500 will be in an unfolded state. When the winding wheel 621 releases the line, the upper umbrella plate and the lower umbrella plate in the umbrella stand body 500 lose the tension and move away from each other, and the umbrella stand body 500 is in a folded state.

[0040] Further, such as Figure 6 and 7 As shown, the top of the umbrella frame body 500 is rotatably connected to the umbrella frame base 400. The umbrella frame base 400 is provided with a stop edge 410 corresponding to the top of the umbrella frame body 500. Initially, the umbrella frame body 500 is in a folded state and can rotate about the axis of the umbrella frame base 400, thereby achieving further folding relative to the upper curved tube 300. When the umbrella frame body 500 is deployed under the pull of the string, it is preferentially driven to rotate about the axis of the umbrella frame base 400. When the top of the umbrella frame body 500 is rotated to a vertical position, the stop edge 410 on the umbrella frame base 400 is retracted, and the umbrella frame body 500 is deployed.

[0041] Furthermore, the umbrella frame body 500 is pulled into an expanded state by the string. Because the ends of the umbrella frame body 500 are defined by the main body of the umbrella frame base 400, they remain perpendicular to the ends of the upper curved tube 300. When the upper curved tube 300 is driven to slide outward or inward, the orientation of the umbrella canopy in the umbrella frame body 500 synchronizes with the movement of the upper curved tube 300, allowing the canopy's angle to be adjusted.

[0042] In this embodiment, an upper bushing and a lower bushing are provided on the lower bend pipe 200 at intervals. A first slot and a second slot are provided on opposite sides of the first shell 611 and the second shell 612 to match the upper bushing and the lower bushing. The first slot and the second slot are respectively provided at the top and bottom of the bayonet holes of the first shell 611 and the second shell 612 to match the lower bend pipe 200. The upper bushing and the lower bushing are embedded in the first slot and the second slot to compensate for the error when the first shell 611 and the second shell 612 are placed on the lower bend pipe 200, while achieving dustproof and waterproof effects on the interior of the first shell 611 and the second shell 612.

[0043] Furthermore, pulleys are provided on both side edges of the bayonet holes of the first shell 611 and the second shell 612 that cooperate with the lower bend pipe 200 to assist the first shell 611 and the second shell 612 in sliding on the lower bend pipe 200 .

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
