Description

Technical Field

[0001] This utility model relates to the technical field of outdoor umbrella counterweight bases, and in particular to a mobile base for outdoor umbrellas. Background Technology

[0002] Sun umbrellas are widely used in people's daily lives. The placement of a sun umbrella mainly relies on the weight of its base for support and fixation. The base is an important component of the sun umbrella, especially for some large umbrellas with a large canopy area, which require a very heavy base, weighing around 100 kilograms, making it particularly difficult to move them.

[0003] To address the difficulty of moving sun umbrella bases, existing bases typically feature four casters at the bottom of the main body, with brakes mounted on each caster. While this design makes movement relatively easy, locking each caster individually is cumbersome. Furthermore, the casters have a small contact area with the ground, resulting in poor stability and a tendency for the sun umbrella to tip over. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] Combination ​ As shown, this utility model discloses a movable base for outdoor umbrellas, including a counterweight base 100, which is typically a plastic water-filled base. The bottom of the counterweight base 100 has a mounting groove 120, within which a moving mechanism 500 is fitted. The moving mechanism 500 includes a flip shaft 510 and a moving wheel 520 fixed to the flip shaft 510. The moving wheel 520 is preferably a universal wheel. In a specific installation structure, a fixed shaft 540 is provided on the flip shaft 510, and the lower end of the fixed shaft 540 is fixedly engaged with a roller seat 521 in the universal wheel. A steering seat 522 is fitted to the lower part of the roller seat 521, and a universal roller 523 is installed inside the steering seat 522. The mounting groove 120 includes a roller cavity groove 121 and a limiting clip. The groove 122 accommodates the movable wheel 520 within the roller cavity groove 121. The flipping shaft 510 engages with the limiting slot 122. In a preferred embodiment, there are two roller cavity grooves 121 and two limiting slots 122. Each roller cavity groove 121 is paired with a single movable wheel 520. The two roller cavity grooves 121 are located outside the two limiting slots 122 and are usually arranged symmetrically. One end of the flipping shaft 510 extends to the outer side of the counterweight base 100 and is installed in conjunction with the flipping handle 200. The flipping handle 200 is usually engaged with the flipping shaft 510 at a 90-degree angle. The flipping handle 200 can drive the flipping shaft 510 to rotate, thereby flipping the movable wheel 520 so that it protrudes from the bottom surface of the counterweight base 100 and makes contact with the ground.

[0027] In conjunction with the above, the mounting groove 120 also includes a receiving groove 124, which is located at the other end of the mounting point of the flip shaft 510 and the flip handle 200. The bottom of the counterweight base 100 is also provided with a handle mounting groove 110. The flip handle 200 can be moved laterally into the handle mounting groove 110 by flipping, and will drive the flip shaft 510 to extend into the receiving groove 124. The handle mounting groove 110 includes a handle rod groove 111 and a handle groove 112. The flip handle 200 includes a handle body 210 and a flip armrest 220. The handle body 210 is accommodated in the handle rod groove 111. In section 1, the flip handle 220 is accommodated in the handle slot 112. In actual use, when the user retracts the flip handle 200, the flip handle 200 is usually flipped until it is horizontal, so that the flip handle 200 and the handle mounting slot 110 are on the same horizontal plane. Then the flip handle 200 is moved inward, and the flip shaft 510 moves to the other end, so that the flip shaft 510 is accommodated in the receiving slot 120, so that the flip handle 200 is correspondingly accommodated in the handle mounting slot 110, thus completing the corresponding accommodating of the handle body 210 and the flip handle 220.

[0028] In conjunction with the above, the mounting groove 120 also includes a limiting groove 123. A limiting shaft 530 is fixedly installed on the flip shaft 510 and is accommodated in the limiting groove 123. A limiting wall 126 and a movable accommodating cavity 127 are provided in the limiting groove 123. The limiting wall 126 is used to limit and abut against the limiting shaft 530. The limiting wall 126 is used to limit and abut against the limiting shaft 530, preventing the flip shaft 510 from continuously flipping. This allows the flip handle 200 to have a corresponding flipping angle. When the limiting shaft 530 abuts against the limiting wall 126, the moving wheel 520 protrudes from the horizontal plane of the bottom surface of the counterweight base 100 and abuts against the ground. The flip handle 200 is at its maximum flipping and unfolding angle. The counterweight base 100 can be moved by the flip handle 200.

[0029] In conjunction with the above, the limiting slot 122 includes a limiting protrusion 125 located at the opening of the shaft cavity groove 128, through which the flip shaft 510 passes. The limiting protrusion 125 is used to restrict the outward protrusion of the flip shaft 510. Preferably, there are two or three limiting slots 122 arranged at intervals. The optimized structural design of the limiting slot 122 facilitates the assembly and installation of the flip shaft 510, and the shaft cavity groove 128 facilitates the rotation of the flip shaft 510.

[0030] In one preferred embodiment, the counterweight base 100 is further provided with a fixing cavity 140 at its bottom, and a fixing roller 300 is provided inside the fixing cavity 140; the number of movable wheels 520 on the flip shaft 510 is preferably two, the number of roller cavity slots 121 is preferably two, and the number of fixing cavities 140 is preferably two, with a single fixing roller 300 provided in each fixing cavity 140; wherein, the fixing roller 300 is installed on both sides of the flip shaft 510, and the counterweight base 100 is provided with an inclined surface 102, the fixing cavity 140 is installed on the inclined surface 102, and after the fixing roller 300 and the fixing cavity 140 are installed, when the counterweight base 100 and the fixed roller 300 are installed, when the counterweight base 100 and the fixed roller 300 are installed, the fixed roller 300 is installed in the fixed cavity 140. When in contact with the ground, the horizontal plane of the lowest surface of the counterweight base 100 is higher than the horizontal plane of the lowest surface of the fixed roller 300, so that the fixed roller 300 cannot contact the ground when the counterweight base 100 is not in use, thus avoiding affecting the counterweight base 100; when the flip handle 200 drives the flip shaft 510 to rotate, the moving wheel 520 protrudes from the bottom surface of the counterweight base 100, forming a lifting structure, so that the moving wheel 520 abuts against the ground. Due to the protrusion of the moving wheel 520, the bottom is tilted, so that the fixed roller 300 on the other side can abut against the ground, forming a four-wheel roller state, which facilitates the overall movement of the counterweight base 100.

[0031] In one preferred embodiment, the counterweight base 100 is further provided with an umbrella column receiving cavity 130 at the bottom, which is used to install the umbrella base column 400; the counterweight base 100 is provided with an umbrella column mounting groove 101 in the middle of the upper surface, which is used to cooperate in installing the umbrella base column 400, so as to facilitate the storage of the umbrella base column 400, increase the storage space, and reduce the transportation volume.

[0032] This utility model features a flip handle that drives a flip shaft to accommodate or roll the moving wheels, improving placement stability and facilitating movement. The optimized mounting groove structure on the bottom surface of the counterweight base, along with the addition of a limiting shaft, prevents excessive deflection of the flip shaft, enhancing operational convenience. Furthermore, the optimized spatial structure of the counterweight base's bottom surface, incorporating a handle mounting groove and an umbrella column mounting groove, facilitates the accommodation of the flip handle and umbrella column, increasing the available space. A fixed roller is added to the side, which, in conjunction with the moving wheels, improves movement stability.

[0033] 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.
