Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, in particular to a lamp tube connecting 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 are more focused on the flexibility, aesthetics and ease of use of lamp design. In particular, in areas such as 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 light tubes are mostly fixed lengths and fixed installation layouts, which to a certain extent limits the possibility of users to freely combine or adjust the light tube layout according to actual needs.

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

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

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A lamp tube connection 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, comprising a connecting outer wall and a first connecting post disposed on the axis of the cylinder; one end of the second joint is also cylindrical, comprising a connecting inner wall capable of interference fit with the connecting outer wall, and a second connecting post is disposed on the axis of the cylinder of the second joint and can be sleeved outside the first connecting post;

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

[0010] At least two contact springs are provided 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 provided 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 the lamp tube. 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 outer wall of the first joint is formed with a first step wall, the outer wall of the second joint is formed with a second step wall, a sleeve is installed between the outer walls of the first joint and the second joint, and the inner wall of the sleeve is sleeved on the first step wall and the second step wall.

[0016] The beneficial effects of the utility model 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 layout.

[0018] 2. The first joint is connected primarily through an interference fit between the cylindrical outer wall and the cylindrical inner wall of the second joint. Both joints are made of a relatively elastic material. When not subjected to external forces, the joints are connected and fixed together through elastic deformation. When appropriate torque is applied, they can rotate. The joints are quick and easy to assemble, making it easy for users to quickly and easily assemble and disassemble the lamp.

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

[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 of diversified lighting layout in commercial displays and home decoration.

[0021] 5. The outer walls of the first joint and the second joint are connected by a sleeve, 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 should be understood that the specific embodiments described herein are merely intended to explain the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of it.

[0031] Reference Figure 1 The utility model provides a lamp tube connection joint, comprising a cylindrical first joint 1 and a cylindrical second joint 2, 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 connector 1 is cylindrical, comprising a connecting outer wall 11 and a first connecting post 12 arranged on the axis of the cylinder; one end of the second connector 2 is also cylindrical, comprising a connecting inner wall 21 that can be interference-fitted with the connecting outer wall 11, and a second connecting post 22 that can be sleeved on the outside of the first connecting post 12 is arranged on the axis of the cylinder of the second connector 2; specifically, the first connector 1 is mainly connected by interference-fitting the cylindrical connecting outer wall 11 with the cylindrical connecting inner wall 21 of the second connector 2. Preferably, the first connector 1 and the second connector 2 are made of a hard material with a certain elasticity, such as synthetic resin. When not subjected to external force, the connectors are connected and fixed to each other through elastic deformation, and can be rotated when appropriate torque is applied. The assembly between the connectors is quick and simple, and the assembly is relatively convenient, allowing users to complete the assembly and disassembly of the lamp tube more conveniently and quickly.

[0033] Reference Figure 3 A cylindrical first contact groove 121 is provided in the middle of the first connecting column 12, a cylindrical second contact groove 221 is provided in the middle of the second connecting column 22 and can be sleeved on the outer wall of the first connecting column 12, and a contact column 220 that 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 linear splicing, but can also achieve rotation at different angles while remaining powered, greatly improving the flexibility of the lamp tube layout.

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

The steering connector 6 includes at least two coaxial steering bodies 60. The first connector 1 or the second connector 2 is fixedly connected to the steering body 60, and the steering bodies 60 can rotate on the coaxial axis. Specifically, the first connector 1 or the second connector 2 connected to the steering connector 6 is also electrically connected, and current conduction is achieved through the conductive slider 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 of 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. 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 connector can conveniently and steplessly adjust the illumination angle according to actual lighting needs, providing a variety of illumination shapes.

The other end of the first connector 1 or the second connector 2 is provided with a pin 50 for being inserted and fixed to the lamp tube 3, and a conductive sheet 51 for electrically connecting to the lamp tube 3. The assembly between the lamp tube 3 and the connector is also relatively simple and quick, reducing installation time and cost.

[0040] A lamp board is provided in the lamp tube 3 , and conductive strips 31 are provided on both sides of the lamp board to abut against the conductive sheet 51 . A light-emitting lamp bead 30 is provided 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 stepped wall 10 on its outer wall, and the second joint 2 has a second stepped wall 20 on its outer wall. A sleeve 4 is installed between the outer walls of the first and second joints 1 and 2, and the inner wall of the sleeve 4 sleeves over the first and second stepped walls 10 and 20. The sleeve 4 connects the outer walls of the first and second joints 1 and 2, which not only enhances the overall stability of the structure but also conceals some of the seams, making the entire lamp joint look simple and smooth, meeting the high aesthetic requirements of modern interior decoration.
