As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.
[0029] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.
[0030] Combination Figure 1 to Figure 3The embodiment of the utility model provides a rotary cross-joint, comprising a cross-joint body 1 and a rotating member 2, wherein the rotating member 2 is rotatably arranged inside the cross-joint body 1, and a limiting groove 151 is provided on the surface of the cross-joint body 1, and the rotating member 2 is limited in the limiting groove 151;
[0031] Among them, any joint on the four-way joint body 1 is connected to the rotating member 2, and when the rotating member 2 rotates, the joint can be linked to move along the limiting groove 151 and change the angle with other joints.
[0032] In the present embodiment, the interior of the four-way joint body 1 is a hollow structure for the rotating member 2 to be rotatably installed therein. A limiting groove 151 is provided on the four-way joint body 1, and the diameter of the limiting groove 151 is adapted to the thickness of the rotating member 2, so that the outer peripheral side of the rotating member 2 is located in the limiting groove 151. When the rotating member 2 rotates, the rotating member 2 is restricted by the limiting groove 151, which can prevent the rotating member 2 from shaking left and right, thereby improving the rotation stability of the rotating member 2.
[0033] In this embodiment, the four-way joint body 1 has four joints, one of which is connected to the rotating member 2. When the rotating member 2 rotates, the joint connected to the rotating member 2 rotates with the rotating member 2. By setting it in this way, one joint on the four-way joint body 1 can adjust the angle relative to the other three joints, thereby realizing the shape switching of the four-way joint body 1. When the linear lamp 3 (see Figure 4 When the four-way joint body 1 is connected to the four-way joint body 1, the splicing shape of the spliced linear lamp 3 can be changed by rotating the joint connected to the rotating member 2 on the four-way joint body 1, thereby meeting the demand for the splicing shape of the lamp space and the scene to be mixed into one.
[0034] It is understandable that the other three joints may also be configured to be rotatable, so as to achieve more splicing shape changes of the spliced linear lamp 3 .
[0035] In one embodiment, the four-way joint body 1 includes a base 15, a first joint 11, a second joint 12, a third joint 13 and a fourth joint 14, a limiting groove 151 is opened on the base 15, the rotating member 2 is arranged in the base 15, the first joint 11 is connected to the rotating member 2, and the second joint 12, the third joint 13 and the fourth joint 14 are fixedly arranged on the base 15.
[0036] In this embodiment, the first joint 11 is rotatable, and the second joint 12, the third joint 13 and the fourth joint 14 are fixed. By rotating the first joint 11, the angle of the first joint 11 relative to the second joint 12, the third joint 13 and the fourth joint 14 can be adjusted to achieve a shape change of the four-way joint body 1, thereby achieving more splicing shape changes of the spliced linear lamp 3.
[0037] In this embodiment, the second joint 12 , the third joint 13 and the fourth joint 14 may be fixed to the base 15 by screws 116 , or may be integrally formed on the base 15 ; in this embodiment, they are preferably integrally formed on the base 15 .
[0038] In one embodiment, the second joint 12 , the third joint 13 and the fourth joint 14 are fixedly arranged on the base 15 on the same plane; the limiting groove 151 is perpendicular to the same plane of the second joint 12 , the third joint 13 and the fourth joint 14 .
[0039] In this embodiment, when the first joint 11 moves along the limiting groove 151 driven by the rotating member 2, the first joint 11 can move to a state where it is at an angle with the same plane as the second joint 12, the third joint 13 and the fourth joint 14, or the first joint 11 can move to a state where it is in the same plane as the second joint 12, the third joint 13 and the fourth joint 14, thereby realizing that the four-way joint body 1 can be transformed into a three-dimensional four-way joint or a cross-shaped plane four-way joint (such as Figure 1 and Figure 2 shown).
[0040] In a more specific embodiment, the rotation angle of the first joint 11 ranges from 0 to 180 degrees.
[0041] In this embodiment, the rotation angle of the first joint 11 can be between 0 and 180 degrees, and in this embodiment it is preferably 90 degrees. By limiting the rotation angle of the first joint 11, when the first joint 11 is rotated for rotational adjustment, the first joint 11 can be in the same plane as the second joint 12, the third joint 13 and the fourth joint 14; when the first joint 11 is rotated to 90 degrees, it can be in a vertical or other angled state with the same plane as the second joint 12, the third joint 13 and the fourth joint 14.
[0042] The rotation angle is the angle between the first joint 11 and the same plane of the second joint 12 , the third joint 13 and the fourth joint 14 .
[0043] It is understandable that the size of the rotation angle is related to the length of the limiting groove 151, that is, the longer the length of the limiting groove 151 is, the greater the range of movement of the first joint 11 in the limiting groove 151, and the greater the rotation angle of the first joint 11 driven by the rotating member 2.
[0044] See also Figure 3 As shown, in one embodiment, the first joint 11 includes an upper shell 112 , a lower shell 113 and a movable member 114 , the movable member 114 passes through the upper shell 112 and the lower shell 113 and is connected to the lower shell 113 , and the lower shell 113 is fixedly connected to the rotating member 2 .
[0045] In this embodiment, the upper shell 112 and the lower shell 113 are connected together through the movable part 114, and the lower shell 113 is fixed to the rotating part 2. Therefore, when the rotating part 2 rotates, the rotating part 2 drives the lower shell 113 to rotate, and the lower shell 113 drives the upper shell 112 to rotate, thereby realizing the overall rotation of the first joint 11.
[0046] In this embodiment, since the rotating part 2 is exposed in the limiting groove 151, the lower shell 113 is connected to the rotating part 2 through the limiting groove 151 through the screw 116, wherein two screws 116 are provided and are respectively located on both sides of the lower shell 113. When the first joint 11 moves to the end of the limiting groove 151, the screw 116 will abut against the wall surface of the base 15, thereby limiting the first joint 11 from continuing to move.
[0047] In this embodiment, the first connector 11 also includes a powered contact plate 111. The top of the upper shell 112 is an open structure. The powered contact plate 111 is arranged in the upper shell 112 and exposed in the opening of the upper shell 112. When the spliced wire-shaped lamp 3 is connected to the first connector 11, the spring pin 31 of the spliced wire-shaped lamp 3 will abut against the powered contact plate 111, thereby realizing the powered connection of the first connector 11 to the spliced wire-shaped lamp 3.
[0048] It is understandable that the tops of the second connector 12 , the third connector 13 and the fourth connector 14 are all open structures, and a power contact plate 111 is arranged in the open structure to facilitate the power connection of other spliced line lamps 3 .
[0049] In one embodiment, the upper shell 112 and the lower shell 113 are rotatably arranged relative to each other, and a wire outlet hole 115 for the wire is opened on the outer circumference of the upper shell 112 .
[0050] In this embodiment, the energized contact plates 111 of the first connector 11, the second connector 12, the third connector 13 and the fourth connector 14 can be connected in parallel to an external power board through wires, thereby achieving interconnection of the electrical appliances.
[0051] In this embodiment, the wires are led out from the wire outlet hole 115 of the upper shell 112, and the upper shell 112 is rotated relative to the lower shell 113. When the upper shell 112 is rotated relative to the lower shell 113, the angle of the outlet hole of the upper shell 112 can be adjusted to meet the needs of users to lead the wires out at various angles of the upper shell 112.
[0052] In one embodiment, the base 15 is a sphere, and a conical recess or an arc-shaped recess for adapting to the outer shape of the sphere is provided on one side of the lower shell 113 connected to the base 15 .
[0053] In this embodiment, the conical depression or the arc-shaped depression can adapt to the surface of the sphere, so that the lower shell 113 and the base 15 can fit more closely, thereby improving the rotation stability of the lower shell 113; more specifically, in this embodiment, the side of the lower shell 113 connected to the base 15 preferably adopts an arc-shaped depression, which can reduce the gap between the arc-shaped depression and the outer shape of the sphere to improve the rotation stability.
[0054] In one embodiment, the rotating member 2 includes a turntable 21 and a fixing member 22 . A mounting portion 152 is disposed in the base 15 . The fixing member 22 is connected to the mounting portion 152 . The turntable 21 is rotatably sleeved on the fixing member 22 .
[0055] In this embodiment, the mounting portion 152 is vertically disposed on the inner wall of the base 15 , and the fixing member 22 may be a pin. The fixing member 22 passes through the turntable 21 and is connected to the mounting portion 152 , so that the turntable 21 can be stably rotated and mounted on the mounting portion 152 .
[0056] See also Figure 2 and Figure 4 As shown, in one embodiment, the outer peripheries of the first joint 11 , the second joint 12 , the third joint 13 and the fourth joint 14 are all provided with a clamping portion 16 , and the clamping portion 16 is used to clamp with the spliced wire lamp 3 to be connected.
[0057] In this embodiment, when the connection port of the spliced wire lamp 3 is sleeved on the periphery of the first joint 11, the second joint 12, the third joint 13 and the fourth joint 14, the connection port of the spliced wire lamp 3 will squeeze the clamping portion 16, so that the clamping portion 16 can increase the friction with the inner side of the connection port of the spliced wire lamp 3, thereby improving the stability of the connection of the spliced wire lamp 3.
[0058] Among them, the clamping part 16 is a protrusion arranged on the periphery of the first joint 11, the second joint 12, the third joint 13 and the fourth joint 14. When the spliced wire lamp 3 is connected to the periphery of the first joint 11, the second joint 12, the third joint 13 and the fourth joint 14, the inner side of the connection port of the spliced wire lamp 3 will squeeze the protrusion, thereby improving the connection stability of the spliced wire lamp 3.
[0059] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
