Description

Technical Field

[0001] This utility model relates to the field of flagpole technology, and in particular to a universal adjustment and locking device for flagpoles. Background Technology

[0002] A flagpole is a pole-shaped object specifically designed to hang, support, and display flags. Its core function is to be held, inserted, or attached to the surface of other objects to achieve portable, decorative, or directional display of flags, typically used in settings such as cars, festival venues, and organizations.

[0003] Traditional flagpoles cannot be freely adjusted in angle, and even after adjustment, they cannot be completely locked in place. This results in poor practicality for traditional flagpoles, lacking the high flexibility of adjustability and making them unsuitable for some complex scenarios. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal adjustment and locking device for flagpoles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A universal adjustment locking device for a flagpole includes a universal ball joint seat, a universal ball joint cover is sleeved on the outer side of the universal ball joint seat and the universal ball joint cover is installed by thread engagement; a universal ball is fixedly provided at the bottom of the flagpole and the universal ball is fixedly installed on the universal ball joint seat by the universal ball joint cover; the universal ball has an internal thread in the middle, and a locking screw is adapted to lock into the internal thread of the universal ball.

[0006] Furthermore, in a preferred configuration, the universal ball joint cover has an inner cavity, and the inner wall of the inner cavity is provided with an internal thread.

[0007] Furthermore, in a preferred configuration, the outer side of the universal ball joint is provided with an external thread, and the external thread of the ball joint and the internal thread of the ball cap are adapted to engage.

[0008] Furthermore, in a preferred configuration, the universal ball joint has an inner cavity that is adapted to the universal ball.

[0009] Furthermore, in a preferred configuration, the flagpole has a vertically penetrating cavity inside, which is adapted to communicate with the universal ball internal thread, and a locking screw is adapted to pass through the cavity.

[0010] Furthermore, in a preferred configuration, the locking wire is provided with an external locking thread, and the external locking thread and the universal ball internal thread are adapted to be interference-fitted.

[0011] The beneficial effects of this utility model are as follows: by setting up the universal ball head seat and the universal ball head cover, the universal ball on the flagpole can be installed in the inner cavity of the ball head seat and rotated to achieve free adjustment of the flagpole. By locking the universal ball through the meshing between the external thread of the locking screw and the internal thread of the universal ball, the universal ball can be locked to lock the flagpole. This device can completely lock the flagpole firmly in any direction and angle, which is highly flexible and convenient for users to use. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-2 A universal adjustment locking device for a flagpole includes a universal ball joint seat 1, a universal ball joint cover 2 sleeved on the outer side of the universal ball joint seat 1, and the universal ball joint cover 2 is installed by thread engagement. A universal ball 32 is fixedly provided at the bottom of the flagpole 3, and the universal ball 32 is fixedly installed on the universal ball joint seat 1 by the universal ball joint cover 2. The universal ball 32 has an internal thread 321 in the middle, and a locking screw 4 is adapted to lock into the internal thread 321 of the universal ball.

[0016] The universal ball joint cover 2 has an inner cavity 22, and the inner wall of the inner cavity 22 is provided with an internal thread 21. The outer side of the universal ball joint seat 1 is provided with an external thread 11, and the external thread 11 and the internal thread 21 of the ball joint cover are fitted and engaged. When the user needs to install the universal ball joint cover 2 on the universal ball joint seat 1, he / she simply puts the universal ball joint cover 2 on the outer side of the universal ball joint seat 1 and rotates the universal ball joint cover 2 to lock the external thread 11 and the internal thread 21 of the ball joint cover into engagement.

[0017] The ball joint 1 has an inner cavity 12, which is adapted to the universal ball 32. By installing the universal ball 32 inside the inner cavity 12 and fitting a universal ball cap 2 on its outer side, the universal ball 32 can be prevented from falling off.

[0018] The flagpole 3 has a vertical through cavity 31 inside, which is adapted to communicate with the universal ball internal thread 321, and the locking wire 4 is adapted to pass through the through cavity 31. The locking wire 4 is provided with a locking wire external thread 41, and the locking wire external thread 41 and the universal ball internal thread 321 are adapted to be interference engaged.

[0019] In this embodiment, when the user needs to assemble the device, simply place the universal ball 32 on the flagpole 3 into the inner cavity 12 of the ball head seat. Then, pass the universal ball head cover 2 through the flagpole 3, and then fit the universal ball head cover 2 onto the universal ball head seat 1. Rotate the universal ball head cover 2 so that the external thread 11 of the ball head seat and the internal thread 21 of the ball head cover engage and lock. This locking mechanism between the universal ball head seat 1 and the universal ball head cover 2 prevents the universal ball 32 from falling out of the inner cavity 12 of the ball head seat.

[0020] Furthermore, at this time, the universal ball joint 1 and the universal ball joint cover 2 are not completely locked to the universal ball 32, so the user can freely adjust the flagpole 3 to adjust the flagpole 3 to a suitable angle.

[0021] When the flagpole 3 is rotated to the appropriate angle, simply insert the locking screw 4 into the through cavity 31. The locking screw 4 then passes through the through cavity 31 and enters the internal thread 321 of the universal ball. Finally, simply use a screwdriver to rotate the locking screw 4 to achieve an interference fit between the external thread 41 of the locking screw 4 and the internal thread 321 of the universal ball. This allows the universal ball 321 to be opened by the locking screw 41, enabling it to be locked within the inner cavity 12 of the ball head seat, thus achieving the locking of the universal ball 321 and the flagpole 3.

[0022] Furthermore, after passing through the internal thread 321 of the universal ball, the locking screw 4 will rest on the inner cavity 12 of the ball head seat to lock the universal ball 32 and the universal ball head cover 2 together. This can further improve the locking effect of the universal ball 32, so as to achieve the fixing effect of the flagpole 3.

[0023] In this invention, by setting up the universal ball joint seat 1 and the universal ball joint cover 2, the universal ball 32 on the flagpole 3 can be installed in the inner cavity 12 of the ball joint seat and rotated to achieve free adjustment of the flagpole 3. By engaging and locking the external thread 41 of the locking screw and the internal thread 321 of the universal ball, the universal ball 32 can be locked to achieve the locking of the flagpole 3. This device can completely lock the flagpole 3 firmly in any direction and angle, which is highly flexible and convenient for users.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
