Description
Technical Field
[0001] The utility model relates to the field of lamp lighting, in particular to a universal joint. Background Art
[0002] Existing LED and fluorescent lamps are widely used as the most common lighting fixtures. Traditional LED and fluorescent lamps include a lamp base and a lamp tube. The lamp base needs to be pre-installed on the indoor ceiling or suspended on the ceiling. In particular, indoors where several LED and fluorescent tubes are installed, they can only be installed in a fixed position and the position relationship of multiple lamp tubes cannot be changed. The light pattern formed by the lighting of several lamp tubes is single and visually dull. I have proposed a patent application technical solution, which can solve these problems. For example, a deformable lamp and a deformable lamp joint disclosed in a Chinese patent (application number 202323544919.0) have connecting gears at both ends of the lamp tube base, or the connecting gears are fixed to both ends of the base through a gear rack. More than two lamps can be connected through the meshing of interconnected gears. As the connecting gears rotate, several deformable lamps can change their relative horizontal positions, change the bright shape of fluorescent lamps, and form different bright geometric figures. However, this scheme has several shortcomings: 1. The scheme says that the relative position of fluorescent tubes can be adjusted to form different shapes, but it only adjusts the relative horizontal positions of several fluorescent tubes through the meshing of interconnected gears. It cannot adjust the relative three-dimensional positions of several fluorescent tubes according to needs, cannot form three-dimensional geometric figures, and the bright shape is not vivid; 2. The installation and adjustment procedures are complicated and costly to connect through the meshing of interconnected gears. Chandeliers are high-end decorations on indoor ceilings. At present, there are no chandelier lamps on the market that can change the bright shape, form bright three-dimensional geometric figures, adjust the lighting brightness range, and the luminous angle of the lamp. Summary of the invention
[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a universal joint, which can change the bright shape of the lamp and form a bright three-dimensional geometric figure. The deformation lamp is easy to install and adjust with low cost.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a universal joint, including a plug and a plug socket, the plug is composed of a plug core or a socket, and a sleeve, the plug core or the socket and the sleeve are installed on the plug socket, and the universal joint is arranged on the plug socket.
[0005] The universal joints include cross-axis universal joints, ball-head universal joints, ball-fork universal joints, and ball-cage universal joints.
[0006] One end of the cross-axis universal joint, ball head universal joint, ball fork universal joint and ball cage universal joint is equipped with a plug to form a one-way universal joint joint.
[0007] The two ends of the cross-axis universal joint, the ball-head universal joint, the ball-fork universal joint and the ball-cage universal joint are equipped with plugs to form a two-way universal joint joint.
[0008] Damping bearings are arranged at both ends of the cross shaft.
[0009] Since the structure and function of the universal joint of this technical solution are a bit like the joints on human limbs, the angle between two or more connected lamps can vary within a certain range. In the case of existing lamps, we can connect more than two lamps through a deformable lamp universal joint joint. The rotation of the universal joint joint can change the relative horizontal positions of several lamps, change the light shapes of more than two lamps, form different bright three-dimensional geometric figures, and also change the lighting brightness range of the lamps and the luminous angle of the lamp tube; similarly, universal joints are provided at both ends of the lamp tube base, and more than two lamps can be connected through the universal joints provided at both ends of the base. As the angle between the connected lamps rotates and changes, several deformable lamps can change their relative horizontal positions and three-dimensional positions, change the light shapes of fluorescent lamps, form different bright three-dimensional geometric figures, and adjust the lighting brightness range and the luminous angle of the lamp tube; the deformable lamp is easy to install and adjust with low cost.

[0040] The universal joints include cross-axis universal joints, ball-head universal joints, ball-fork universal joints, and ball-cage universal joints.
[0041] The universal joint can be directly mounted on the base 4, or mounted on the base 4 through the bracket 3 (such as Figure 2 shown),
[0042] The left and right universal joint forks 2 and 6 of the cross-axis universal joint are installed on the base 4, and the adjacent deformable lamps are connected by the cross shaft 1. The two ends of the cross shaft 1 are provided with damping bearings 10, which are installed in the shaft hole 2-1. The two ends of the cross shaft 1 can also be directly installed in the shaft hole 2-1, so that the left and right universal joint forks 2 and 6 can stay at any position in the air, so that the adjacent deformable lamps can be shaped at any position in the air;
[0043] The two ends of the ball cage universal joint are connected to the two deformable lamp bases 4. With the rotation of the spherical shell 19, the ball cage 20 and the inner raceway 21, the two deformable lamp bases 4 change their positions, so that the adjacent deformable lamps can be shaped at any position in the air.
[0044] Ball-head universal joints can also be installed at both ends of the deformable lamp base 4, with an outer ball head 8 and an inner ball head 7 respectively installed at both ends of the deformable lamp base 4, the outer ball heads 8 of adjacent deformable lamps are connected to the inner ball heads 7, the inner ball 15 fits with the spherical surface of the outer ball heads 8, and the damping movement of the outer ball heads 8 and the inner ball heads 7 enables the adjacent deformable lamps to be shaped at any position in the air; ball-fork universal joints can also be installed at both ends of the base 4, with the left and right universal joint ball forks 13 and 11 respectively installed at the two ends of the deformable lamp base 4, and the adjacent deformable lamps are connected with a center ball 14, and the friction between the fork grip 12 and the center ball 14 enables the adjacent deformable lamps to be shaped at any position in the air;
[0045] A universal joint comprises a plug and a plug socket 9. The plug is composed of a plug core 17 or a plug hole 16 and a sleeve 18. The plug core 17 or the plug hole 16 and the sleeve 18 are mounted on the plug socket 9. The universal joint is arranged on the plug socket 9.
[0046] The universal joints include cross-axis universal joints, ball-head universal joints, ball-fork universal joints, and ball-cage universal joints.
[0047] The cross-axis universal joint, ball-end universal joint, ball-fork universal joint, and ball-cage universal joint are provided with a plug at one end to form a one-way universal joint (such as Fig.11 —— Fig.16 , Fig.18 ).
[0048] The cross-axis universal joint, ball-end universal joint, ball-fork universal joint, and ball-cage universal joint are equipped with plugs at both ends to form a two-way universal joint (such as Figure 3-3 , Figure 7 — Fig.10 ).
[0049] The cross shaft 1 is provided with damping bearings 10 at both ends. According to the needs of lamp installation, lamp plugs can be installed at both ends of the universal joint, or at one end; the plug is composed of a plug core 17 and a sleeve 18, and can also be composed of a socket 16 and a sleeve 18 to form a universal joint.
[0050] Six deformable lamps are engaged in the hanging space to form an overall geometric shape. Two lamp bases 4 are hung by ropes 22, which are fixed to the ceiling by fixed piles 23. The remaining four deformable lamps are engaged with universal joints to form an overall geometric shape. Fig.19 — Fig. 22 Solid geometric shapes.
[0051] More than two deformable lamps can be connected to each other through universal joints. With the rotation of the universal joints, several deformable lamps can change their relative horizontal positions, change the position shapes of multiple lamp tubes 5, form different bright three-dimensional geometric figures, and adjust the lighting brightness range and the light-emitting angle of the deformable lamps; in the case of existing lamps, we insert the universal joint plug core 17 or the socket 16 into the adjacent lamp socket or plug core, the sleeve 18 wraps the adjacent lamp base 4, the universal joint on the plug seat 9 is engaged with the universal joint on another plug seat 9, and several lamps are connected to each other through the engagement of the universal joint. The rotation of the universal joint can also arbitrarily change the horizontal and three-dimensional positions of several deformable lamps, change the bright shape, form different bright three-dimensional geometric figures, and change the lighting brightness range and the light-emitting angle of the lamp.
[0052] When using, select several deformable lamps according to the needs of different geometric shapes. Select six to transform Fig.19 — Fig. 22 The more three-dimensional geometric shapes there are, the more variable three-dimensional geometric shapes there are.
[0053] The structure and function of the universal joint are a bit like the joints on the human body. The angle between two or more connected lamps can vary within a certain range. We have made use of the structural characteristics of the universal joint to change the position between two or more lamps and perform three-dimensional geometric deformation of the light, giving the universal joint a new use.

They are not listed one by one and are all within the protection scope.
