Description

Technical Field

[0001] The utility model belongs to the technical field of sun umbrellas, and particularly relates to an umbrella base adjusting device. Background Art

[0002] As the name suggests, an outdoor umbrella is a parasol or sun umbrella used outdoors, usually composed of an umbrella base, an umbrella pole and an umbrella body. Traditional outdoor umbrellas are mostly fixed structures. Since the angle and direction of the umbrella surface cannot be adjusted, the use of this type of fixed structure outdoor umbrella is relatively simple. Therefore, rotating outdoor umbrellas have appeared on the market. This type of rotating outdoor umbrella usually adjusts the direct sunlight angle of the parasol by horizontally rotating 360 degrees.

[0003] In the prior art, a PCT application with application number "PCT / IB2023 / 000186" and name: CANTILEVER UMBRELLA discloses an umbrella seat adjustment device, in which a limit groove is provided on the upper part of the turntable seat, and a snap structure that cooperates with the limit groove is provided on the foot pedal.

[0004] In the aforementioned patent, the inner surface of the turntable seat requires multiple limit grooves that mate with the snap-on structure, making it difficult to manufacture. Furthermore, the limit grooves and snap-on structure used for locking are exposed. When switching from the unlocked to the locked state, the snap-on structure is locked by plugging the ends together. During the locking process, the ends of the snap-on structure may catch on the foot, posing a safety hazard. Furthermore, the friction between the turntable seat and the base is high, which is time-consuming, labor-intensive, and unsightly. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, the utility model provides an umbrella base adjustment device to solve the technical problems of high difficulty in processing the limiting device in the umbrella base and the potential safety hazard of feet being caught during the switching process.

[0006] In order to achieve the above purpose, the specific technical solutions of the present utility model are as follows:

[0007] An umbrella base adjustment device includes a foot tube, a turntable assembly, a limit gear plate, and a locking assembly. The turntable assembly includes a mounting base and a rotating base. The rotating base is rotatably connected to the mounting base. The foot tube is fixed to the rotating base.

[0008] The limiting toothed disc is fixed on the foot tube, and a plurality of limiting tooth grooves are formed on the outer ring. The locking assembly controls the locking or unlocking of the rotating limiting toothed disc by engaging with or disengaging from the corresponding limiting tooth grooves.

[0009] Furthermore, the locking assembly includes a locking member and a reset member. The mounting base is provided with a mounting bracket that cooperates with the locking member. The middle portion of the locking member is rotatably connected to the mounting bracket. The locking member can switch between locking and unlocking the limit gear disc in conjunction with the reset member.

[0010] Furthermore, the reset member is an elastic member.

[0011] Furthermore, the locking member comprises an inner locking end and an outer driving end. Initially, the locking end engages with the limiting tooth groove of the limiting toothed disc. When pressure is applied to the driving end, the locking end disengages from the limiting tooth groove of the limiting toothed disc, unlocking the limiting toothed disc. The reset member is capable of resetting the locking member when the pressure applied to the outer end of the locking member is released.

[0012] Furthermore, the reset member is a V-shaped reset spring, which is sleeved on the rotating shaft of the locking member, with its two ends respectively abutting against the bottom surface of the locking member and the mounting frame.

[0013] Furthermore, the locking assembly further comprises a foot pedal which is fixed to the driving end of the locking member via screws.

[0014] Furthermore, the mounting base is provided with a clearance hole that cooperates with the leg tube, and a mounting groove that cooperates with the limiting toothed disc is provided at the bottom. The bottom of the leg tube passes through the clearance hole and extends into the mounting groove. The limiting toothed disc is disposed in the mounting groove and is fixed to the bottom of the leg tube.

[0015] Furthermore, a steel ball receiving groove is provided between the mounting base and the rotating base. A plurality of steel balls are arranged in the steel ball receiving groove to form a rotational fit between the mounting base and the rotating base.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. The present invention utilizes a cooperating locking element and a position-limiting toothed disc. The locking element engages or disengages from the corresponding position-limiting toothed disc under the control of a return spring, thereby controlling the locking or unlocking of the rotating position-limiting toothed disc. Furthermore, both the locking end of the locking element and the position-limiting toothed disc are positioned within a mounting groove at the bottom of the mounting base, effectively avoiding potential safety hazards associated with the exposed locking end.

[0018] 2. This utility model provides a steel ball receiving groove between the mounting base and the rotating base. Multiple steel balls are placed in the groove. The sliding motion of the steel balls reduces friction between the mounting base and the rotating base, facilitating rotation and adjustment while extending the life of the device.

[0019] 3. In the present invention, the foot pedal and the locking member are fixed by screws, so that the foot pedal and the locking member can be processed independently and then assembled, which reduces the processing difficulty. BRIEF DESCRIPTION OF THE DRAWINGS
