[0031] In addition, the terms "first" and "second" are only used for descriptive purposes, and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality of" means at least two, unless otherwise specifically defined.

[0032] In the present utility model, unless otherwise clearly defined and limited, terms such as "mounted", "connected", "connected to", "fixed" and the like should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0034] As Figures 1-3 shown, a connection structure for a table lamp base and a lamp head includes a base 1, a sleeve 3, a ball head assembly 2 and a bearing assembly 4.

[0035] The sleeve 3 is fixedly arranged inside the base 1; the ball head assembly 2 is inserted into the sleeve 3; the bearing assembly 4 is sleeved on one end of the ball head assembly 2 located inside the sleeve 3; wherein, the ball head assembly 2 is rotatably arranged inside the sleeve 3 through the bearing assembly 4.

[0036] During actual use, the user can adjust the irradiation angle of the illuminating lamp body through one end of the ball head assembly 2, and can also adjust the rotation angle of the illuminating lamp body in the horizontal plane through the other end of the ball head assembly 2. The multi-directional adjustment makes the adjustment of the irradiation angle of the table lamp more flexible. And the angle adjustment can be realized only by relying on the bearing assembly 4, which makes the manufacturing cost lower and improves the economy of the enterprise.

[0037] Specifically, the ball head assembly 2 includes a ball head seat 21 and a fixing rod 22.

[0038] The ball head seat 21 is used to connect the illuminating lamp body; one end of the fixing rod 22 is connected to the ball head seat 21, and the other end is inserted into the sleeve 3.

[0039] One end of the ball head seat 21 inserted into the sleeve 3 is connected to the bearing assembly 4, so that the ball head seat 21 can rotate along the horizontal plane of the base 1, achieving the purpose of angle adjustment and improving the user experience.

[0040] Specifically, the fixing rod 22 is in a stepped shape.

[0041] The whole fixing rod 22 is divided into two sections with different diameters. The section with a smaller diameter is inserted into the sleeve 3, and the section with a larger diameter is located outside the sleeve 3, so it presents a stepped shape.

[0042] Through the above solution, during processing, the installation method of the fixing rod 22 can be quickly identified. The section with a smaller diameter can be directly aligned and installed inside the sleeve 3, improving the assembly efficiency.

[0043] Specifically, the bearing assembly 4 includes a bearing body 41 and a locking nut 42.

[0044] The bearing body 41 is sleeved on the fixing rod 22; the locking nut 42 is threadedly connected to one end of the fixing rod 22 and presses the bearing body 41 onto the fixing rod 22. In this embodiment, the bearing body 41 is a plain bearing.

[0045] When the locking nut 42 presses the plain bearing onto the fixing rod 22, the fixing rod 22 can reciprocally rotate in the horizontal plane under the action of the plain bearing.

[0046] Further, a receiving groove 5 is arranged on one side of the sleeve 3 facing the base 1, and the receiving groove 5 is used to receive the bearing assembly 4.

[0047] Further, the sleeve 3 is fixedly arranged on the base 1 by screws.

[0048] Further, the ball seat 21 is threadedly connected to the fixing rod 22.

[0049] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
