Description

Technical Field

[0001] The invention relates to the technical field of lighting fixtures, and in particular to a lamp tube joint. Background Art

[0002] With the continuous development of lighting technology, people's requirements for lamps are no longer limited to basic lighting functions, but pay more attention to the flexibility, aesthetics and ease of use of lamp design. Especially in the fields of commercial display and home decoration, the demand for personalized lighting layout is growing.

[0003] Although there are cuttable LED light strips on the market that allow users to cut and connect them to the required length, such products often face problems such as high installation complexity and easy damage at the joints. Traditional lamp tubes are mostly designed with fixed lengths and fixed installation arrangements, which to a certain extent limits the possibility of users to freely combine or adjust the layout of lamp tubes according to actual needs.

[0004] Therefore, the development of a new type of lamp tube connector has become an urgent need in the industry. The ideal solution can easily splice multiple lamp tubes as needed, and can flexibly change the illumination and arrangement direction of the lamp tubes according to actual conditions, so as to achieve the best lighting effect, providing a new type of connector device that is simple and easy to use and can greatly enrich the application scenarios of lamp tubes. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a lamp tube joint, which has the characteristics of simple lamp tube splicing and the ability to adjust the irradiation direction of the lamp tube while keeping the power on.

[0006] The technical solution adopted by the present invention to solve the technical problem is:

[0007] A lamp tube joint, comprising a first joint in the form of a cylinder and a second joint in the form of a cylinder, wherein one end of the first joint is electrically connected to one end of the second joint and can rotate relative to each other in an axial direction;

[0008] One end of the first joint is cylindrical, and includes a connecting outer wall and a first connecting column arranged on the axis of the cylinder; one end of the second joint is also cylindrical, and includes a connecting inner wall that can be interference-fitted with the connecting outer wall, and a second connecting column that can be sleeved outside the first connecting column is arranged on the axis of the cylinder of the second joint;

[0009] A first cylindrical contact groove is arranged in the middle of the first connecting column, a second cylindrical contact groove which can be sleeved on the outer wall of the first connecting column is arranged in the middle of the second connecting column, and a contact column which can be inserted into the first contact groove is arranged in the middle of the second contact groove.

[0010] At least two contact springs are arranged on the inner wall of the first contact groove. When the contact column is inserted into the first contact groove, the contact springs can abut against the contact column. The outer wall of the first connecting column is wrapped with an outer contact sheet, and the inner wall of the second contact groove is provided with an annular inner contact sheet that can abut against the outer contact sheet.

[0011] The other ends of the first joint or the second joint are connected to each other to form a steering joint, and the steering joint includes at least two coaxial steering bodies, and the first joint or the second joint is fixedly connected to the steering body, and the steering bodies can rotate on the coaxial line.

[0012] Connecting bolts are arranged on the coaxial lines of the steering bodies. Tightening or loosening the connecting bolts can lock or unlock the mutual rotation between the steering bodies.

[0013] The other end of the first connector or the second connector is connected to a lamp tube, and the other end of the first connector or the second connector is provided with a pin for being plugged and fixed to the lamp tube, and a conductive sheet for being electrically connected to the lamp tube.

[0014] A lamp board is arranged in the lamp tube, conductive strips abutting against the conductive sheet are arranged on both sides of the lamp board, and a light-emitting lamp bead is arranged in the middle of the lamp board.

[0015] The first joint outer wall is formed with a first step wall, the second joint outer wall is formed with a second step wall, a sleeve is installed between the first joint and the second joint outer wall, and the sleeve inner wall is sleeved on the first step wall and the second step wall.

[0016] The beneficial effects of the present invention are:

[0017] 1. The design that the first joint and the second joint can rotate relative to each other along the axial direction makes the connection between the joints not limited to simple straight-line splicing, but can also achieve rotation at different angles while maintaining power, greatly improving the flexibility of the lamp tube layout.

[0018] 2. The first joint is mainly connected by interference fit between the cylindrical outer wall and the cylindrical inner wall of the second joint. The first joint and the second joint are made of a material with a certain elasticity. When no external force is applied, the joints are connected and fixed to each other through elastic deformation. When appropriate torque is applied, they can rotate. The assembly between the joints is quick and simple, and the assembly is relatively convenient, so that users can complete the assembly and disassembly of the lamp tube more conveniently and quickly.

[0019] 3. The contact spring in the first contact groove is connected to the contact column, and the inner contact piece of the second contact groove is connected to the outer contact piece outside the first connection column, ensuring that the first connector and the second connector can maintain a good electrical connection even in the case of relative rotation, effectively avoiding light flickering or circuit breaking caused by poor contact, and improving the stability and safety of product use.

[0020] 4. When the other end of the first joint or the second joint is connected to form a steering joint, the overall degree of freedom is increased. Not only can the first joint and the second joint be rotated, but the first joint and the second joint as a whole can also rotate on the coaxial line of the steering joint, which broadens the application scenarios of the lamp tube and is suitable for various lighting environments, further meeting the needs for diversified lighting layout in commercial displays and home decoration.

[0021] 5. The outer walls of the first joint and the second joint are connected through a sleeve pipe, which not only enhances the overall stability of the structure, but also hides part of the joint, making the appearance of the entire lamp tube joint simple and smooth, meeting the high requirements of modern interior decoration for aesthetics.

It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

[0031] Reference Figure 1 The present invention provides a lamp tube joint, comprising a first joint 1 in the form of a cylinder and a second joint 2 in the form of a cylinder, wherein one end of the first joint 1 is electrically connected to one end of the second joint 2 and can rotate relative to each other in the axial direction;

[0032] Reference Figure 2 , Figure 3 One end of the first joint 1 is cylindrical, and includes a connecting outer wall 11 and a first connecting column 12 arranged on the axis of the cylinder; one end of the second joint 2 is also cylindrical, and includes a connecting inner wall 21 that can be interference-fitted with the connecting outer wall 11, and a second connecting column 22 that can be sleeved outside the first connecting column 12 is arranged on the cylinder axis of the second joint 2; specifically, the first joint 1 is mainly connected by interference-fitting the cylindrical connecting outer wall 11 with the cylindrical connecting inner wall 21 of the second joint 2. Preferably, the first joint 1 and the second joint 2 are made of a hard material with a certain elasticity, such as synthetic resin. When not subjected to external force, the joints are connected and fixed to each other through elastic deformation, and can rotate when appropriate torque is applied. The assembly between the joints is quick and simple, and the assembly is relatively convenient, so that users can complete the assembly and disassembly of the lamp tube more conveniently and quickly.

[0033] Reference Figure 3 A first cylindrical contact groove 121 is provided in the middle of the first connecting column 12, a second cylindrical contact groove 221 which can be sleeved on the outer wall of the first connecting column 12 is provided in the middle of the second connecting column 22, and a contact column 220 which can be inserted into the first contact groove 121 is provided in the middle of the second contact groove 221.

[0034] Furthermore, by designing that the first joint 1 and the second joint 2 can rotate relative to each other along the axial direction, the connection between the joints is not limited to simple straight-line splicing, but can also achieve rotation at different angles while maintaining power, greatly improving the flexibility of the lamp tube layout.

[0035] Reference Figure 3At least two contact springs 122 are arranged on the inner wall of the first contact slot 121. When the contact column 220 is inserted into the first contact slot 121, the contact springs 122 can abut against the contact column 220. The outer wall of the first connecting column 12 is wrapped with an outer contact sheet 123. The inner wall of the second contact slot 221 is provided with an annular inner contact sheet 222 that can abut against the outer contact sheet 123. Specifically, the contact spring 122 in the first contact slot 121 is connected to the contact column 220, and the inner contact sheet 222 of the second contact slot 221 is connected to the outer contact sheet 123 outside the first connecting column 12. The contact springs 122 are arranged in a bent sheet shape and are symmetrically arranged on both sides of the diameter of the first contact slot 121. When the contact column 220 is inserted, it can abut against the contact column 220. The inner contact sheet 222 also has a certain elasticity to abut against the outer contact sheet 123. This ensures that the first connector 1 and the second connector 2 can maintain good electrical connection even when they rotate relative to each other, effectively avoiding light flickering or circuit breaking problems caused by poor contact, and improving the stability and safety of the product.

Specifically, the first joint 1 or the second joint 2 connected to the steering joint 6 is also electrically conductive, and the current conduction is achieved through the conductive sliding sheet between the steering bodies 60.

[0037] Furthermore, the steering joint 6 increases the overall degree of freedom. Not only can the first joint 1 and the second joint 2 rotate, but the first joint 1 and the second joint 2 as a whole can also rotate on the coaxial line of the steering joint 6, which broadens the application scenarios of the lamp tube and is suitable for various lighting environments, further meeting the needs for diversified lighting layout in commercial displays and home decoration.

[0038] Furthermore, a connecting bolt 61 is provided on the coaxial line of the steering body 60, and tightening or loosening the connecting bolt 61 can lock or unlock the mutual rotation between the steering bodies 60. That is, the lamp on the lamp tube joint can conveniently and steplessly adjust the irradiation angle according to actual lighting needs, and has a variety of irradiation shapes.

[0039] Reference Figure 2 , Figure 4 The other end of the first connector 1 or the second connector 2 is connected to the lamp tube 3, and the other end of the first connector 1 or the second connector 2 is provided with a plug 50 for being plugged and fixed to the lamp tube 3, and a conductive sheet 51 for being electrically connected to the lamp tube 3. The assembly between the lamp tube 3 and the connector is also relatively simple and quick, reducing the installation time and cost.

[0040] A lamp board is laid in the lamp tube 3 , and conductive strips 31 abutting against the conductive sheet 51 are arranged on both sides of the lamp board. A light-emitting lamp bead 30 is arranged in the middle of the lamp board. Preferably, the light-emitting lamp bead 30 is an LED lamp bead.

[0041] Reference Figure 2 The first joint 1 has a first step wall 10 on its outer wall, and the second joint 2 has a second step wall 20 on its outer wall. A sleeve tube 4 is installed between the first joint 1 and the second joint 2, and the inner wall of the sleeve tube 4 is sleeved on the first step wall 10 and the second step wall 20. The first joint 1 and the second joint 2 are connected by the sleeve tube 4, which not only enhances the overall stability of the structure, but also hides part of the joint, making the appearance of the entire lamp joint simple and smooth, meeting the high requirements of modern interior decoration for aesthetics.

[0042] In summary, this new type of lamp tube connector not only solves the problems existing in traditional lamp tube connections, but also innovatively proposes a more user-friendly and practical solution, providing users with a new option for lamp tube connection with superior performance, easy operation and beautiful appearance.
