The left and right inclination adjustment mechanism includes a inclination adjustment operating member 500, a pull rope 501, a joint locking member 502 and a joint elastic reset member 503. The joint locking member 502 locks the boom joint 4 on the umbrella column assembly so that the boom joint 4 cannot rotate. The pull rope 501 is connected between the joint locking member 502 and the inclination adjustment operating member 500. The inclination adjustment operating member 500 drives the joint locking member 502 to move through the pull rope 501 to complete the unlocking action of the joint locking member 502. The joint elastic reset member 503 acts on the joint locking member 502 to keep the joint locking member 502 in a locked state.

[0037] It can be understood that in the above technical solution, the boom joint 4 of the present invention is rotatably cooperated with the umbrella column assembly, and the left and right inclination of the umbrella frame assembly 7 can be adjusted by rotating the boom joint 4. In addition, the present invention is provided with a left and right inclination adjustment mechanism, and the locking and unlocking actions of the boom joint 4 are realized through the left and right inclination adjustment mechanism. The left and right inclination adjustment mechanism has a simple structure, a reasonable design, and is easy to operate, which greatly improves the user experience of the present invention.

[0038] Continuing to refer to Figures 1 and 6, the umbrella column assembly includes a lower bend tube 1, an upper bend tube 2, an armrest mechanism 3 and an elbow seat 6. The upper bend tube 2 is slidably inserted into the lower bend tube 1, and the armrest mechanism 3 realizes the locking of the upper and lower bend tubes and the opening and closing of the umbrella surface. The elbow seat 6 is installed on the upper end of the upper bend tube 2 through fasteners. A rotating connecting shaft 8 is provided on the center of the end face of the elbow seat 6. The boom joint 4 is rotatably sleeved on the rotating connecting shaft 8. The rotating connecting shaft 8 causes the edge of the end face of the elbow seat 6 to form an annular step surface. A number of locking holes 600 for inserting with the joint locking member 502 are evenly distributed on the annular step surface. The locking hole 600 is a through hole or a blind hole or a groove. The joint locking member 502 adopts a locking pin. The joint locking member 502 realizes the left and right inclination adjustment of the umbrella frame assembly 7 by cooperating with the locking holes 600 in different positions.

[0039] In other embodiments, it may also be configured that a rotating connecting shaft 8 is fixed on the boom joint 4 , and the elbow seat 6 is rotatably sleeved on the rotating connecting shaft 8 .

[0040] In other embodiments, when the pressure applied by the joint elastic reset member 503 to the joint locking member 502 is large enough, the joint locking member 502 can directly bend the seat 6 without providing a locking hole 600.

[0041] Continuing to refer to Figures 2, 4 and 6, the joint locking member 502 and the joint elastic reset member 503 are arranged on the boom joint 4, wherein a mounting groove 400 is provided on the boom joint 4, the joint locking member 502 and the joint elastic reset member 503 are both provided in the mounting groove 400, and the joint locking member 502 slides with the mounting groove 400, the joint elastic reset member 503 is a spring, one end of which is connected to the joint locking member 502, and the other end is connected to the inner wall of the mounting groove 400, which pushes the joint locking member 502 toward the side of the elbow seat 6.

[0042] In other embodiments, the joint elastic return member 503 may be a V-shaped spring, a torsion spring, a tension spring, or other structures. The V-shaped spring is used similarly to a spring; when a torsion spring is used, the joint elastic return member 503 is designed to be rotatably connected to the boom joint 4; when a tension spring is used, one end of the tension spring is connected to the elbow seat 6 and the other end is connected to the joint elastic return member 503, pulling the joint locking member 502 toward the elbow seat 6.

[0043] 1 , in one embodiment of the present invention, there are two tilt adjustment operating members 500 , which are respectively disposed on the left and right edges of the umbrella frame assembly 7 , and each tilt adjustment operating member 500 is connected to a joint locking member 502 via a pull rope 501 .

[0044] Furthermore, the inclination adjustment operating member 500 can be any one of a wrench, a button, a knob, and a hand wheel. In the present invention, the inclination adjustment operating member 500 is preferably a wrench. When the inclination adjustment operating member 500 is pulled, the inclination adjustment operating member 500 can pull the pull rope 501, thereby driving the joint locking member 502 to move.

[0045] When adjusting the inclination of the umbrella surface, the user can hold the inclination adjustment operating member 500 with one hand and pull the inclination adjustment operating member 500. The inclination adjustment operating member 500 drives the joint locking member 502 to exit the corresponding locking hole 600 through the pull rope 501, completing the unlocking action of the joint locking member 502, and then adjust the left and right inclination of the umbrella surface by moving the inclination adjustment operating member 500. The whole process can be operated with one hand, which is very convenient.

[0046] Continuing to refer to Figures 3 and 5, in one embodiment of the present invention, in order to ensure the smooth movement of the pull rope 501, the left and right inclination adjustment mechanism also includes a pull rope pulley and a rope guide frame 504. The pull rope pulley is arranged on the umbrella frame assembly 7 and the boom joint 4, and the rope guide frame 504 is built into the umbrella ribs of the umbrella frame assembly. The pull rope pulley and the rope guide frame 504 are both used to guide the pull rope 501.

[0047] It should be noted that the left and right inclination adjustment in the present invention is essentially performed by rotating the umbrella surface along the circumferential direction of the upper end surface of the umbrella column assembly.

[0048] Continuing to refer to Figure 1, the side wall of the above-mentioned lower bend tube 1 is provided with an opening 100 along its length direction, the upper bend tube 2 is slidably inserted into the lower bend tube 1, and the armrest mechanism 3 is provided at the lower end of the upper bend tube 2 and extends from the opening 100 of the lower bend tube 1 for human operation, which locks the upper bend tube 2 on the lower bend tube 1.

[0049] As can be understood, in the above technical solution, the present invention provides an opening 100 on the lower bend tube 1, exposing a portion of the upper bend tube 2. This reduces the contact area between the lower bend tube 1 and the upper bend tube 2, thereby reducing the possibility of jerking, jamming, and other unsmooth movements of the upper bend tube 2, thereby improving the user experience. Furthermore, the movement of the upper bend tube 2 can be controlled via the armrest mechanism 3, which lowers the operating position and enhances operational convenience.

[0050] 7 and 8 , in one embodiment of the present invention, the lower bend pipe 1 is preferably a round pipe, and the curvature of the opening 100 thereof is 15°-180°.

[0051] Continuing to refer to Figures 9 and 10, in one embodiment of the present invention, the armrest mechanism 3 includes an armrest shell 300, a bend pipe locking operating member 301, a bend pipe elastic reset member 302 and a bend pipe locking member 303. The armrest shell 300 is installed on the upper bend pipe 2, and the bend pipe locking member 303 locks the upper bend pipe 2 on the lower bend pipe 1. The bend pipe locking operating member 301 is movably provided on the armrest shell 300, which drives the bend pipe locking member 303 to move to realize the locking and unlocking actions of the bend pipe locking member 303. The bend pipe elastic reset member 302 presses the bend pipe locking member 303 and is used to realize the reset of the bend pipe locking member 303 and the bend pipe locking operating member 301.

[0052] It can be understood that in the above technical solution, the armrest mechanism 3 of the present invention is provided with an armrest shell 300, a bend pipe locking operating member 301, a bend pipe elastic reset member 302 and a bend pipe locking member 303 and other structures. It has a simple structure and a reasonable design, which realizes the locking of the upper and lower bend pipes and improves the convenience of the telescopic operation of the upper bend pipe 2.

[0053] Further referring to Figure 10, the armrest shell 300 includes an armrest body 3000 and an armrest mounting portion 3001. The armrest mounting portion 3001 is located inside the lower bend tube 1 and is sleeved on the bottom of the upper bend tube 2. It slides up and down with the lower bend tube 1. The armrest body 3000 is an armrest ring structure with a gripping hole, which extends from the opening 100 of the lower bend tube 1 for human operation. The bend locking operating member 301 slides back and forth in the armrest body 3000, and partially extends from the gripping hole of the armrest body 3000 for human operation.

[0054] In one embodiment of the present invention, the elbow elastic return member 302 is a spring, which is housed in the armrest body 3000, with its two ends respectively connected to the inner wall of the armrest body 3000 and the side of the elbow locking operating member 301 facing away from the armrest mounting portion 3001. The elbow locking operating member 301 and the armrest body 3000 have a groove structure and a protruding column structure for installing the spring.

[0055] In other embodiments, the above-mentioned elbow elastic reset member 302 can adopt a V-shaped spring, a torsion spring or other structures. The usage of the V-shaped spring is similar to that of a spring. When a torsion spring is used, the elbow locking operating member 301 is designed to be rotatably connected to the armrest body 3000.

[0056] In other embodiments, the above-mentioned elbow elastic return member 302 can also be connected to the armrest shell 300 and the elbow locking member 303 to press the elbow locking member 303 toward the lower elbow 1.

[0057] In one embodiment of the present invention, the elbow locking member 303 adopts a pin, and the elbow locking operating member 301 is designed to be an annular structure corresponding to the structure of the armrest body 3000. The pin is fixedly connected to the end of the elbow locking operating member 301 facing away from the armrest mounting portion 3001. The side wall of the lower elbow 1 is provided with a plurality of insertion holes 101 at intervals along its length direction. The insertion holes 101 are through holes, blind holes or grooves. The pin passes through the shell wall of the armrest mounting portion 3001 and the upper elbow 2 and is plugged into the insertion holes 101 to lock the upper elbow 2 on the lower elbow 1. The height of the upper elbow 2 is adjusted by the cooperation of the pin and the insertion holes 101 of different heights.

[0058] In other embodiments, when the pressure applied by the elbow elastic reset member 302 to the elbow locking operating member 301 is large enough, the lower elbow 1 can be directly pressed by the elbow locking member 303 without providing the insertion hole 101.

[0059] Continuing to refer to Figures 8 and 9, in one embodiment of the present invention, two groups of sliding protrusions 305 are set at intervals on the upper and lower sides of the side of the armrest mounting portion 3001. The sliding protrusions 305 are pulley structures. The inner wall of the lower curved tube 1 is provided with sliding grooves 102 along its length direction. The pulley structure slides on the sliding grooves 102, which makes the upper curved tube 2 slide more smoothly.

[0060] Among them, the axes of the two sets of pulleys and the axis of the handrail mounting portion 3001 are perpendicular to each other, which can increase the rolling contact area between the pulleys and the inner wall of the lower curved pipe 1, thereby improving the sliding smoothness of the upper curved pipe 2.

[0061] In other embodiments, the sliding protrusion 305 can also be a protrusion or a protrusion, and the positions of the sliding protrusion 305 and the sliding groove 102 can be interchanged, that is, the inner wall of the lower bend pipe 1 is provided with a sliding protrusion 305 along its length direction, and the outer wall of the handrail mounting part 3001 is provided with a sliding groove 102.

[0062] In addition, the armrest mechanism 3 of the present invention further includes a crank assembly 304 provided on the armrest shell 300. The crank assembly 304 controls the opening and closing of the umbrella surface through a traction rope. The conventional structure of the armrest mechanism 3 in the crank assembly 304 is not described in detail.

[0063] The working mode of the armrest mechanism 3 in the present invention is as follows:

[0064] Under normal circumstances, the spring presses the pin through the elbow locking operating member 301, so that the pin is firmly inserted into the corresponding socket 101. When the height of the upper elbow 2 needs to be adjusted, the elbow locking operating member 301 is pressed, and the elbow locking operating member 301 compresses the spring and drives the pin to disengage from the socket 101, completing the unlocking. After the height adjustment of the upper elbow 2 is completed, the elbow locking operating member 301 is released, the spring recovers and drives the elbow locking operating member 301 and the pin to reset, and the pin is inserted into the corresponding socket 101.

[0065] 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.
