Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor parasols, and particularly relates to a wrench-rotating umbrella seat. Background Art

[0002] In the prior art, parasols are primarily used to block direct sunlight. Due to the sun's motion, the angle of the sun's rays changes over time. To achieve optimal sun protection, parasols must be adjusted. A rotating umbrella base is a component on a parasol used to adjust the angle.

[0003] The Chinese patent publication number "CN214904320U" discloses a rotating umbrella stand, including a rotating base, a sleeve welding part and a foot pedal assembly, wherein the sleeve welding part includes a sleeve and a base plate, the sleeve is vertically inserted into the middle position of the upper end surface of the base plate and welded to the base plate, the rotating base is sleeved outside the sleeve and located above the base plate, the lower end of the parasol's column is sleeved outside the sleeve and plugged into the rotating base for positioning, the foot pedal assembly includes a foot pedal and a foot pedal shaft, the foot pedal is reset and rotatably mounted on one side of the upper end of the rotating base, the foot pedal shaft is vertically arranged at the lower end of the inner side of the foot pedal, the foot pedal shaft passes through the rotating base and cooperates with the positioning hole on the base plate, and is locked and disengaged with the base plate through the foot pedal, thereby realizing the clamping and rotation of the rotating base.

[0004] To operate the rotating base, if the canopy needs to be rotated, the user first steps on the pedal to disengage the rotating disc from the locking pin. Then, by holding the umbrella's uprights, they rotate the canopy, which slowly rotates horizontally with the ground. While doing this, the user needs to simultaneously monitor both the pedaling and the rotation of the uprights, requiring them to multitask. For large outdoor umbrellas, ensuring the uprights are stable during rotation can be challenging, leading to wobbling. This makes rotating the umbrella column relatively inconvenient for the user, impacting the user's operational experience. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, the utility model provides a wrench-rotating umbrella seat to solve the technical problem of the inconvenience of operating the prior art rotating umbrella seat.

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

[0007] A wrench rotating umbrella mount comprises a mounting base, an inner vertical tube, an outer vertical tube, and a locking structure. The inner vertical tube is fixed to the mounting base. The outer vertical tube is positioned over the outer ring of the inner vertical tube and forms a rotational engagement with the inner vertical tube. The locking structure is disposed between the inner and outer vertical tubes and controls the locking or unlocking of the rotating outer vertical tube.

[0008] The locking mechanism includes a toothed disc, a rotational sleeve, and a locking assembly. The toothed disc is fixed to the top of the inner riser. The rotational sleeve is fixed to the outer riser and forms a rotational engagement with the toothed disc.

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 and 2 As shown, a wrench-type rotating umbrella holder comprises a mounting base 1, an inner tube 2, an outer tube 3, and a locking structure 4. The inner tube 2 is fixed to the mounting base 1. The outer tube 3 is a circular tube that fits over the outer ring of the inner tube 2, forming a rotational engagement with the inner tube 2. The locking structure 4 is disposed between the inner and outer tubes 2 and 3, controlling the locking or unlocking of the rotating outer tube 3.

[0031] The specific structure is as follows: Figure 3 As shown, locking structure 4 includes a sprocket 5, a first spacer bearing 6, a rotational sleeve 7, and a locking assembly 8. Sprocket 5 is fixed to the top of inner riser 2. Rotational sleeve 7 is fixed to outer riser 3 and connected to sprocket 5 via first spacer bearing 6, allowing rotational sleeve 7 to rotate relative to sprocket 5. Locking assembly 8 is mounted on outer riser 3 and locks or unlocks outer riser 3 by engaging or disengaging the teeth on sprocket 5.

[0032] In this embodiment, a first connecting hole is defined through the upper sidewall of the rotating sleeve 7, and a second connecting hole corresponding to the first connecting hole is defined on the outer tube 3. A first pin sleeve is provided on the outer tube 3, which mates with the first and second connecting holes. The inner end of the pin sleeve passes through the first and second connecting holes, respectively, securing the outer tube 3 to the rotating sleeve 7.

[0033] Furthermore, a vertically extending stop hole is formed in the rotating sleeve 7. The stop hole has a stepped structure. A stop shaft is positioned within the stop hole. The bottom of the stop shaft is fixedly connected to the inner riser 2, defining the relative position between the rotating sleeve 7 and the toothed disc 5. The toothed disc 5, the inner riser 2, and the stop shaft are fixedly connected via a second pin sleeve.

[0034] Specifically, a first fixing hole is defined at the bottom of the position-limiting connecting shaft. A second fixing hole is defined on the inner riser 2, communicating with the first fixing hole. An integrally formed connecting edge is defined at the bottom of the toothed disc 5. This connecting edge defines a third fixing hole, communicating with the second fixing hole. The inner end of the second pin sleeve sequentially passes through the third fixing hole, the second fixing hole, and the first fixing hole, thereby locking the relative positions of the toothed disc 5, the inner riser 2, and the position-limiting connecting shaft.

[0035] like Figure 3-6 As shown, the locking assembly 8 includes a fixed sleeve 8-1 and a wrench 8-2. The fixed sleeve 8-1 is fixed to the outer vertical tube 3 and has a first clearance groove on its outer surface. The outer vertical tube 3 has a second clearance groove connecting the first clearance groove and the inner cavity of the outer vertical tube 3. The wrench 8-2 is rotatably connected to the fixed sleeve 8-1 and has an integrally formed locking member 8-3 on its inner end. The locking member 8-3 passes through the first and second clearance grooves and extends into the inner cavity of the outer vertical tube 3. The outer end of the locking member 8-3 has a locking groove that matches the tooth groove of the toothed disc 5.

[0036] like Figure 5-7 As shown, in the initial state, wrench 8-2 is rotated upward to its limit position, and the locking groove at the outer end of locking member 8-3 engages the tooth groove on the toothed disc 5, locking the outer tube 3 relative to the inner tube 2 and preventing the outer tube 3 from rotating. When the outer tube 3 needs to be rotated and adjusted, wrench 8-2 is moved downward, driving locking member 8-3 in synchronous movement, and the locking groove at the outer end of locking member 8-3 gradually disengages from the tooth groove on the toothed disc 5. The outer tube 3 is unlocked, allowing it to be adjusted to any angle relative to the inner tube 2.

[0037] In this embodiment, the fixing sleeve 8 - 1 and the outer standpipe 3 are connected by rivets.

[0038] Furthermore, a mounting groove is provided at the rotating end of the wrench 8-2. A torsion spring 8-4 is embedded in the inner wall of the mounting groove. The inner end of the torsion spring 8-4 is fixed to the inner wall of the mounting groove, and the outer end is against the outer surface of the fixed sleeve 8-1. When the user bends the wrench 8-2 downward, the torsion spring 8-4 is deformed. When the user removes the pressure applied to the wrench 8-2, the torsion spring 8-4 is reset, driving the wrench 8-2 to rotate upward, so that the locking groove at the outer end of the locking member 8-3 provided on the wrench 8-2 is inserted into the tooth groove on the toothed disc 5, thereby locking the relative position of the outer standpipe 3 and the inner standpipe 2.

[0039] In this embodiment, the mounting base 1 includes a counterweight seat 1-1 and two profile members 1-2. The counterweight seat 1-1 includes two counterweight blocks. The two counterweight blocks are semicircular structures, forming a disc-shaped structure when closed. Receiving grooves are provided on the opposite sides of the two counterweight blocks. When the two counterweight blocks are brought close together, a receiving cavity is formed between them. The two profile members 1-2 are arranged in the receiving cavity and are cross-arranged to form a cross structure. A clearance hole that cooperates with the outer vertical tube 3 is provided at the top of the receiving cavity. The bottom of the inner vertical tube 2 and the outer vertical tube 3 extend into the receiving cavity from the clearance hole.

[0040] Furthermore, an integral mounting plate is fixed to the bottom of the inner riser 2. The mounting plate is screwed to the two profiles 1-2. A riser locating sleeve 9 is embedded and fixed to the bottom of the outer riser 3. A second spacer bearing is provided between the riser locating sleeve 9 and the mounting base 1, enabling the rotational connection between the outer riser 3 and the mounting bracket, thereby enabling the outer riser 3 to rotate relative to the inner riser 2.

[0041] In addition, in this embodiment, a standpipe cover 10 is provided on the bottom of the outer standpipe 3. The bottom of the standpipe cover 10 abuts against the top surface of the counterweight to improve the stability of the outer standpipe 3 during rotation.

[0042] Example 2

[0043] like Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the counterweight seat 1-1 is a square structure, and the outer vertical tube 3 is a special-shaped structure with two parallel opposite sides and two arc-shaped side edges.

[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.
