[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As attached Figure 1-2 As shown, the lampshade for an anti-glare lamp involved in the utility model comprises an outer shell 1, an inner shell 2, a light shield 3, a ball joint connection structure 4, and a dustproof sponge ring 5.

[0020] The outer shell 1 and the inner shell 2 are cavity structures with an opening at the bottom, which can be disc-shaped or square-shaped. A light-transmitting cover 21 is arranged at the opening at the bottom of the inner shell 2, and the light-transmitting cover 21 is made of PVC transparent material. A plurality of heat dissipation holes 22 are arranged on the upper side of the inner shell 2, and the light board 1 is fixedly arranged at the top of the inner cavity of the inner shell 2.

[0021] The inner shell 2 is arranged inside the outer shell 1 , and the top surface is connected to the top surface of the inner cavity of the outer shell 1 through a ball joint connection structure 4 .

[0022] The ball joint connection structure 4 includes an upper ball joint part 41 and a lower ball joint part 42, wherein the upper ball joint part 41 is fixed to the central position of the top surface of the inner cavity of the outer shell 1, and the lower ball joint part 42 is fixed to the central position of the outer top surface of the inner shell 2, and the upper ball joint part 41 is provided with a spherical table-shaped cavity, wherein the upper cross-sectional radius is smaller than the lower part, and the upper part of the lower ball joint part 42 is a spherical table-shaped cavity that matches the spherical table-shaped cavity of the upper ball joint part 41, and the upper square spherical table-shaped cavity of the lower ball joint part 42 can be embedded in the spherical table-shaped cavity provided with the upper ball joint part 41, and a plurality of grooves q1 are provided on the upper square spherical table-shaped cavity of the lower ball joint part 42.

[0023] The upper ball joint 41 and the outer shell 1 are integrally formed, and the lower ball joint 42 and the inner shell 2 are integrally formed.

[0024] The lower side wall of the outer shell 1 is provided with an inwardly protruding ring portion 11 , the inner diameter of the protruding ring portion 11 is less than or equal to the outer diameter of the inner shell 2 , and the lowest point of the lower part of the outer shell 1 is lower than the lowest point of the lower part of the inner shell 2 .

[0025] A dustproof sponge ring 5 is provided in the gap between the lower inner wall of the outer shell 1 and the outer wall of the inner shell 2. The dustproof sponge ring 5 can close the gap between the outer shell 1 and the bottom of the inner shell 2 to reduce the entry of dust and will not affect the rotation of the inner shell 2 around the ball joint connection structure 4.

[0026] As attached Figure 3 As shown, the lower part of the housing 1 is also provided with a slidably connected light shield 3, which is a part of the side of a truncated cone with a central angle between 120 and 180 degrees, and the upper part is slidably connected to the housing 1. The specific slidable connection is that the lower part of the housing 1 has a protruding ring part 11, and grooves or protrusions are provided on both sides. Figure 2 As shown, a groove is provided, and a U-shaped structure is provided on the upper part of the light shield 3. The distance between the two side surfaces of the U-shaped structure is consistent with the width of the protruding ring part 11, and a protrusion or a groove is provided at the corresponding position of the groove or protrusion of the protruding ring part 11, which cooperate with each other to realize a slidable connection.

[0027] The top or side of the outer shell 1 is connected to the lamp. When in use, the illumination direction of the light panel 1 can be fine-tuned by pushing the inner shell 2 by hand. This adjustment method is simple and intuitive, and has a good user experience. The lampshade is particularly suitable for table lamps, especially table lamps without a lamp head adjustment structure. In addition, since the outer shell 1 completely wraps the inner shell 2, the distance between the light panel 1 and the lower opening of the outer shell 1 is relatively far, which can also greatly reduce the impact of glare.

[0028] As attached Figure 4 As shown, further, a plurality of annular protrusions 21a are provided at the bottom of the light-transmitting cover 21, so as to facilitate positioning when the inner shell 2 is pushed or rotated by hand during use.

[0029] Furthermore, different areas of the light-transmitting cover 21 are covered with different anti-glare films. For example, two partitions are provided, each occupying half of the area of ​​the light-transmitting cover 21. The glare film effects of the two groups of anti-glare films are different. By rotating the inner shell 2, different light-transmitting effects can be achieved on the side close to the use side.

[0030] As attached Figure 5 , 6 As shown, in order to further improve the structural strength and optimize the hand feel (damping, paragraph feel and other hand feel experience), the ball joint connection structure 4 also includes a metal ball joint 43, which is located in the spherical table-shaped cavity of the upper ball joint part 41 and the lower ball joint part 42, and the upper and lower ends of the metal ball joint 43 are respectively fixed to the center of the upper ball joint part 41 and the lower ball joint part 42. A plurality of annular protrusions w lines are arranged on the contact surfaces in the spherical table-shaped cavity of the upper ball joint part 41 and the lower ball joint part 42, and the protrusion height is less than 1mm, so that a certain paragraph feel can be achieved during rotation.

[0031] It should be noted that, unless otherwise clearly specified and limited, the terms such as "install", "connect", "connect", "fix", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
