Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a damping connection structure and a lighting fixture. Background Technology

[0002] In actual use, lighting fixtures often require adjustments to their illumination angle and position. Currently, many lighting fixtures on the market use bolt-fastened connections to adjust and fix the angles between components. This type of connection requires using tools such as wrenches to loosen the bolts, adjust the angle, and then tighten them again to secure them. This repeated tightening and loosening of bolts is cumbersome and time-consuming, significantly impacting installation and usage efficiency. Furthermore, over time, the bolts are prone to wear and loosening, making it impossible to maintain a fixed lighting angle.

[0003] In addition, the tightness of the bolts directly affects the stability of the connection and the smoothness of the adjustment. If the bolts are too tight, it will be difficult to adjust the lamps and make it difficult to achieve precise angle adjustment; if they are too loose, the fixing effect cannot be guaranteed, and it will be difficult to meet the needs of modern diverse scenarios for flexible and stable adjustment of lighting equipment.

[0004] Therefore, how to achieve flexible and stable adjustment of the working angle of the connection structure is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To facilitate operators in rotating the lamp and prevent it from rotating excessively due to inertia, ensuring smooth rotation within a defined angle range and achieving precise angle adjustment, this application provides a damping connection structure and a lamp.

[0006] The damping connection structure and lighting fixture provided in this application adopt the following technical solution:

[0007] First aspect

An mounting arm is fitted onto the outer end of the screw. A nut is threaded onto the screw corresponding to the mounting arm. The nut abuts against the mounting arm. A damping element is fitted onto the screw, and the damping element elastically abuts between the screw and the nut.

[0009] Furthermore, a mounting hole is provided on the side wall of the cylinder corresponding to the screw, the screw is inserted into the mounting hole, and a limiting part is provided at the inner end of the screw to prevent the screw from sliding out of the mounting hole.

[0010] Furthermore, a first washer is attached to the screw on the outer sleeve of the mounting arm. One end of the first washer abuts against the cylinder, and the other end of the first washer away from the cylinder abuts against the mounting arm.

[0011] Furthermore, a second washer is fitted inside the mounting arm on the screw, one end of the second washer abutting against the nut, and the other end of the second washer away from the nut abutting against the damping element.

[0012] Furthermore, the damping element is made of an elastic material and is arranged in a spiral shape.

[0013] Furthermore, the mounting arm is provided with a first mounting part corresponding to the position of the screw, and the cylinder is provided with a second mounting part corresponding to the position of the screw. The second mounting part is rotatably connected to the first mounting part. The second mounting part is provided with a first sliding plane, and a first limiting protrusion is fixedly installed on the first sliding plane. The first mounting part is provided with a second sliding plane corresponding to the first sliding plane, and a second limiting protrusion is fixedly installed on the second sliding plane corresponding to the first limiting protrusion.

[0014] Furthermore, the central angle of the first limiting protrusion corresponding to the center of the screw is α, and the central angle of the second limiting protrusion corresponding to the center of the screw is β, satisfying: α+β<360°.

[0017] Second aspect

[0018] A lighting fixture includes a lighting fixture body, which is installed inside the cylinder of the damping connection structure described in the first aspect.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] This application utilizes a spirally arranged damping component that is tightly connected to the screw, nut, and other parts to rotatably connect the cylinder to the mounting arm. This eliminates the need for tools such as wrenches to adjust the working angle of the cylinder, making it convenient for operators. When the cylinder rotates, the damping force provided by the damping component prevents the cylinder from rotating excessively due to inertia, ensuring smooth rotation within a defined angle range and achieving precise angle adjustment. Simultaneously, the damping component can quickly generate elastic deformation during operation, effectively buffering and absorbing the impact and vibration generated during rotation, ensuring the stability of the connection structure during long-term use of the cylinder.

[0031] Example 1

[0032] This application discloses a damping connection structure.

[0033] Please refer to Figures 1 to 6 In one embodiment of this application, a damping connection structure includes a cylindrical body 100, a screw 200 rotatably connected to the cylindrical body 100, the outer end of the screw 200 penetrating the side wall of the cylindrical body 100, an mounting arm 300 fitted on the outer end of the screw 200, the mounting arm 300 being fixedly connected to the screw 200, a nut 400 threadedly connected to the screw 200 corresponding to the mounting arm 300, the nut 400 abutting against the mounting arm 300, and a damping element 500 fitted on the screw 200, the damping element 500 elastically abutting between the screw 200 and the nut 400.

[0034] During operation, the cylinder 100 and the mounting arm 300 can rotate. When the cylinder 100 rotates, the damping element 500 will undergo a certain degree of elastic deformation to adapt to the angle change of the cylinder 100. The damping force generated by the damping element 500 always maintains elastic contact with the screw 200 and the nut 400. When the cylinder 100 rotates to the required angle, the damping element 500 relies on its own elastic restoring force to tightly abut between the screw 200 and the nut 400, thereby fixing the cylinder 100 at that angle position. Even if the lamp is subjected to slight vibration or external impact, the damping force provided by the damping element 500 can prevent the cylinder 100 from rotating easily, ensuring the stability of the entire connection structure during the adjustment process.

[0035] Please refer to Figures 1 to 6 It is understood that in other embodiments of this application, the mutual rotation between the cylinder 100 and the mounting arm 300 can be achieved as long as any two of them form a rotatable connection.

[0036] Please refer to Figures 1 to 6 In one embodiment of this application, a mounting hole 107 is provided on the side wall of the cylinder 100 corresponding to the screw 200. The screw 200 is inserted into the mounting hole 107. A limiting part 201 is provided at the inner end of the screw 200 to restrict the screw 200 from sliding out of the mounting hole 107.

[0037] During operation, as the screw 200 gradually inserts into the mounting hole 107 until its outer end protrudes from the side wall of the cylinder 100, the limiting part 201 will come into contact with the inner wall of the cylinder 100. At this time, the limiting part 201 prevents the screw 200 from moving outward, ensuring that the screw 200 is correctly installed on the cylinder 100. At the same time, the limiting part 201 will continue to function during the rotation of the cylinder 100 or in use, preventing the screw 200 from slipping out of the mounting hole 107.

[0038] The design of the limiting part 201 clarifies the installation position and method of the screw 200, and prevents the screw 200 from sliding out of the mounting hole 107, thereby ensuring that the screw 200 will not detach from the cylinder 100, and ensuring the reliability and stability of the entire damping structure.

[0039] Please refer to Figures 1 to 6 In one embodiment of this application, a first gasket 101 is attached to the screw 200 and the mounting arm 300. One end of the first gasket 101 abuts against the cylinder 100, and the other end of the first gasket 101 away from the cylinder 100 abuts against the mounting arm 300.

[0040] During operation, when the angle of the cylinder 100 is adjusted, there is a relative movement tendency between the cylinder 100 and the mounting arm 300. The first shim 101 will be subjected to pressure and friction between the two. The first shim 101 can keep the contact surface of the cylinder 100 and the mounting arm 300 flat, increase the contact area, avoid direct friction between the mounting arm 300 and the cylinder 100, reduce the wear of the mounting arm 300 and the cylinder 100, and extend the service life of the entire connection structure.

[0041] Please refer to Figures 1 to 6 In one embodiment of this application, a second washer 102 is sleeved on the screw 200 inside the mounting arm 300. One end of the second washer 102 abuts against the nut 400, and the end of the second washer 102 away from the nut 400 abuts against the damping member 500.

[0042] During operation, adjusting the angle of the cylinder 100 will generate a certain axial force on the nut 400. This axial force will be transmitted to the damping element 500 through the second washer 102. The second washer 102 can keep the contact surfaces of the nut 400 and the damping element 500 flat, increase the contact area, thereby buffering the direct impact of the nut 400 on the damping element 500, avoiding damage to the damping element 500 due to excessive pressure, extending the service life of the damping element 500, and ensuring its long-term stable damping function. The second washer 102 can also reduce the friction between the nut 400 and the damping element 500, making the tightening and loosening of the nut 400 easier.

[0043] Please refer to Figures 1 to 6 In one embodiment of this application, the damping element 500 is made of an elastic material and is arranged in a spiral shape.

[0044] During operation, when the cylinder 100 rotates, the helical damping element 500 undergoes elastic deformation. This elastic deformation generates a damping force opposite to the direction of rotation, hindering the rotation of the cylinder 100 and allowing the operator to more precisely control the speed and amplitude of rotation. When the cylinder 100 rotates to the desired angle, the damping element 500, relying on its own elastic restoring force, returns to its initial shape to a certain extent. At this point, the damping element 500 maintains elastic contact with the mounting arm 300 and the nut 400. The friction generated by this elastic contact fixes the cylinder 100 at that angle, ensuring the stability of the entire connection structure.

[0045] In one specific embodiment of this application, the damping element 500 can be made of polyurethane rubber, which has a high damping coefficient and can generate a large damping force, providing good effect for precise adjustment and stable fixation of the cylinder 100 angle; or it can be made of shape memory alloy, which has strong spatial adaptability and can be made into damping elements of various shapes and sizes to adapt to helical winding settings. After installation, it can fit tightly between the mounting arm 300 and the nut 400 through its own shape memory characteristics, ensuring the stability of the damping effect.

[0046] Please refer to Figures 1 to 6 In one embodiment of this application, a first mounting part 301 is provided on the mounting arm 300 at the position corresponding to the screw 200, and a second mounting part 103 is provided on the cylinder 100 at the position corresponding to the screw 200. The second mounting part 103 is rotatably connected to the first mounting part 301. A first sliding plane 104 is provided on the second mounting part 103, and a first limiting protrusion 105 is fixedly installed on the first sliding plane 104. A second sliding plane 106 is provided on the first mounting part 301 corresponding to the first sliding plane 104, and a second limiting protrusion 302 is fixedly installed on the second sliding plane 106 corresponding to the first limiting protrusion 105.

[0047] During operation, when the cylinder 100 rotates, the second sliding plane 106 on the first mounting part 301 slides on the first sliding plane 104 of the second mounting part 103 on the cylinder 100. Simultaneously, the first limiting protrusion 105 on the first sliding plane 104 and the second limiting protrusion 302 on the second sliding plane 106 cooperate with each other. When the first limiting protrusion 105 and the second limiting protrusion 302 contact, the rotation of the cylinder 100 is restricted, thereby limiting the range of rotation angle of the cylinder 100.

[0048] When the nut 400 is locked to the screw 200, the damping element 500 between the second washer 102 and the first washer 101 will be compressed. As the nut 400 continues to rotate, its final position will be restricted by the first limiting protrusion 105. Since the compression amount X of the damping element 500 is a constant value, according to the elastic force formula F=KX, where K is the elastic coefficient and X is the deformation, the elastic force (friction force) of the damping element 500 is also a constant value after the nut 400 is locked to the screw 200. Therefore, this damping structure can provide stable and consistent damping.

[0049] This design allows the cylinder 100 to adjust its working angle flexibly and stably, while preventing damage to the cylinder 100 and its internal structure due to excessive rotation, thus enhancing the stability and reliability of the connection structure.

[0050] Please refer to Figures 1 to 6 In one embodiment of this application, the first mounting part 301 is configured as a boss on the mounting arm 300, and the second mounting part 103 is configured as a concave surface on the cylinder 100 corresponding to the boss. By embedding the boss on the mounting arm 300 into the concave surface of the cylinder 100, a stable nested rotating connection structure is formed. This boss-concave surface matching design can effectively reduce the space occupied during installation, making the overall structure more compact. On the other hand, the concave surface can provide lateral constraint for the boss, preventing radial displacement between the mounting arm 300 and the cylinder 100 during rotation, further enhancing the stability of the connection.

[0051] Please refer to Figures 1 to 6 In one specific embodiment of this application, the central angle of the first limiting protrusion 105 corresponding to the center of the screw 200 is α, and the central angle of the second limiting protrusion 302 corresponding to the center of the screw 200 is β. α is designed to be 45° and β is designed to be 30°. This allows for precise control of the rotation range of the cylinder 100 within 0°-285°. The defined rotation range reduces the uncertainty of the cylinder 100 during rotation and improves its stability during use.

[0052] Please refer to Figures 1 to 6In one embodiment of this application, a protective cover 304 is provided on the end of the first mounting part 301 away from the screw 200, and a third limiting protrusion 303 is provided inside the first mounting part 301. A buckle 305 is provided on the protective cover 304 corresponding to the third limiting protrusion 303. The protective cover 304 is fastened to the first mounting part 301 through the buckle 305 and the third limiting protrusion 303.

[0053] During operation, the buckle 305 on the protective cover 304 is aligned with the third limiting protrusion 303 inside the first mounting part 301, and then a certain external force is applied to make the protective cover 304 and the first mounting part 301 fasten together. At this time, the buckle 305 will tightly lock the third limiting protrusion 303, forming a stable connection.

[0054] The protective cover 304 is designed to prevent dust, moisture, debris and other contaminants from entering the interior of the first mounting section 301, thus avoiding corrosion, wear or short circuits to internal components due to long-term exposure and extending the service life of the entire device. At the same time, it prevents operators from accidentally touching live parts or sharp edges inside the first mounting section 301 during daily use, reducing the risk of electric shock or injury and improving the safety of the device.

[0055] Please refer to Figures 1 to 6 In one embodiment of this application, a mounting bracket 306 is fixedly connected to one end of the mounting arm 300 away from the first mounting part 301.

[0056] During operation, the mounting arm 300 is threadedly connected to the mounting bracket 306. At the same time, the mounting bracket 306 can be fixedly connected to the wall, ceiling, light pole, etc. by threaded fasteners, which greatly enhances the installation flexibility of the entire device and can meet the working needs of different scenarios.

[0057] The implementation principle of a damping connection structure in this application is as follows:

[0058] When the cylinder 100 rotates on the mounting arm 300, the damping component fitted on the screw 200 will undergo elastic deformation due to its elastic material properties and spiral winding structure. Through deformation, it absorbs and consumes the energy brought by external force, making the rotation of the cylinder 100 more stable and ensuring the stability of the connection structure.

[0059] When the cylinder 100 rotates clockwise or counterclockwise, a compressive or tensile force is generated on the damping element 500, thereby increasing or decreasing the elastic deformation of the damping element 500. As the damping element 500 undergoes continuous deformation and energy conversion, it consumes the energy of the cylinder 100's rotation, thus producing a damping effect, hindering the rotation of the cylinder 100, and making the rotation process smooth and slow. At the end of the rotation, the external force disappears or decreases, and the damping element 500, based on the properties of its elastic material, generates an elastic restoring force. This restoring force prompts the damping element 500 to attempt to return to its initial shape, thereby stabilizing the cylinder 100 in its current position and preventing it from swaying due to slight external forces or its own inertia.

[0060] Example 2

[0061] This application discloses a lamp.

[0062] Please refer to Figures 1 to 6 In one embodiment of this application, a lamp includes a lamp body 600, which is installed inside a cylinder 100 of a damping connection structure according to Embodiment 1. One end of the cylinder 100 is a closed structure, and the other end is an opening. The lamp body 600 is installed in the opening, and light is emitted from the opening end of the cylinder 100.

[0063] During operation, the main body 600 of the lamp is fixedly installed inside the cylinder 100. The illumination angle of the lamp can be adjusted by rotating the cylinder 100. At the same time, the presence of the damping structure makes the adjustment of the illumination angle of the lamp easy and precise. Without the need for complicated tools, the operator can directly adjust it manually, which greatly improves the adjustment efficiency and meets the needs of precise adjustment of the lamp angle in different scenarios.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
