Description

Technical Field

[0001] This invention relates to the field of lighting fixture accessories technology, and in particular to a lighting fixture assembly and disassembly device. Background Technology

[0002] Traditional indoor lighting fixtures are mostly designed to be fixed high up, such as on the ceiling, to cover a wider lighting area. In related technologies, to facilitate the disassembly and maintenance of the fixtures, suction cups, grippers, or other holding components are usually installed at the end of a long pole to hold the fixture, replacing the need for operators to climb to heights. However, since the fixtures are installed at a high position, the length of the long pole must be adapted to the installation location. This not only makes it difficult to flexibly arrange the position of the long pole when disassembling and assembling the fixture, but also makes it difficult to store the long pole when not in use, affecting the convenience of use. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0020] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] Understandably, referring to Figure 1 , Figure 2 and Figure 4 ,as well as Figures 6 to 9 The lamp assembly / disassembly device of the present invention includes a telescopic mechanism 100 and a gripping mechanism 200. The telescopic mechanism 100 includes an outer telescopic rod 110 and an inner telescopic rod 120. The outer telescopic rod 110 includes multiple first sleeves 111 connected in sequence, and adjacent first sleeves 111 can slide relative to each other along the axial direction. The inner telescopic rod 120 is installed inside the outer telescopic rod 110 and includes multiple second sleeves 121 connected in sequence, and adjacent second sleeves 121 can slide relative to each other along the axial direction. The inner telescopic rod 120 and the outer telescopic rod 110 can rotate relative to each other, and the two ends of the outer telescopic rod 110 and the two ends of the inner telescopic rod 120 are fixed relative to each other axially so that the outer telescopic rod 110 and the inner telescopic rod 120 can extend and retract synchronously. The gripping mechanism 200 includes a transmission assembly 210 and a functional component 220. The transmission assembly 210 is connected to the inner telescopic rod 120. The transmission assembly 210 is used to drive the functional component 220 to move. The functional component 220 is used to grip the lamp.

[0023] The outer telescopic rod 110 includes multiple first sleeves 111 connected in sequence, enabling the outer telescopic rod 110 to extend and retract axially. The inner telescopic rod 120 is arranged inside the outer telescopic rod 110, and the inner telescopic rod 120 includes multiple second sleeves 121 connected in sequence. By setting the two ends of the outer telescopic rod 110 and the two ends of the inner telescopic rod 120 respectively to be fixed axially relative to each other, the outer telescopic rod 110 and the inner telescopic rod 120 can extend and retract synchronously. This not only facilitates the positioning of the gripping mechanism 200 to adapt to different lamp installation heights, but also allows for convenient storage when not in use, improving ease of use.

[0024] The transmission assembly 210 is connected to the inner telescopic rod 120. By setting multiple second sleeves 121, they can abut against each other in the circumferential direction. When one of the second sleeves 121 is driven to rotate, the inner telescopic rod 120 can rotate in the outer telescopic rod 110, so that the transmission assembly 210 can drive the functional component 220 to move. This facilitates the operation of the functional component 220, enabling it to grab the lamp and easily install or remove it. This reduces the maintenance difficulty of the lamp, eliminates the need for climbing, and improves operational safety and maintenance convenience.

[0025] It should be noted that the two ends of the outer telescopic rod 110 and the two ends of the inner telescopic rod 120 are fixed axially relative to each other so that when the outer telescopic rod 110 is pulled to extend or retract, the inner telescopic rod 120 can extend or retract synchronously. This allows for easy adjustment of the position of the functional component 220, which not only adapts to the installation height of the lamps, but also allows the telescopic mechanism 100 to be retracted during transportation, facilitating passage through narrow spaces such as doorways and improving the ease of installation and arrangement of the telescopic mechanism 100.

[0026] In addition, the inner telescopic rod 120 can rotate relative to the outer telescopic rod 110, so that when the operator is operating, one hand can hold the outer telescopic rod 110 so that the functional component 220 can hold the lamp, and the other hand can rotate the inner telescopic rod 120 to operate the functional component 220 to hold the lamp, which simplifies the lamp disassembly and assembly process and improves the convenience of maintenance.

[0027] The lamp fixture includes a lamp holder and a lamp body, with the lamp body detachably connected to the lamp holder. The lamp body can be mounted on the lamp holder via a threaded connection or a rotating locking connection, and can be removed from the lamp holder by rotating it.

[0028] Specifically, the transmission assembly 210 may include a screw and a nut, or a gear and a rack, or a crank-connecting rod mechanism, so that the inner telescopic rod 120 can be connected to the transmission assembly 210 to drive the functional component 220 to move; the functional component 220 may be a suction cup 223, a gripper 228, etc., and the transmission assembly 210 can drive the suction cup 223 to adsorb or release the lamp, or drive the gripper 228 to grasp or release the lamp, which is not limited here.

[0029] Understandably, referring to Figure 4 and Figure 8 The transmission assembly 210 includes a fixed base 211 and a screw 212. The fixed base 211 is fixed to the end of the outer telescopic rod 110. The screw 212 is fixedly connected to the inner telescopic rod 120 and threadedly connected to the fixed base 211. The screw 212 is also connected to the functional component 220 to drive the functional component 220 to move. When the inner telescopic rod 120 is rotated, the screw 212 can move axially along the fixed base 211, thereby driving the functional component 220 to move, enabling the functional component 220 to grasp or release the lamp body, improving operational convenience.

[0030] One end of the inner telescopic rod 120 is connected to the fixed base 211 by a screw 212, so that one end of the outer telescopic rod 110 and one end of the inner telescopic rod 120 are fixed relative to each other in the axial direction, so that the outer telescopic rod 110 and the inner telescopic rod 120 can extend and retract synchronously.

[0031] Specifically, refer to Figure 4The functional component 220 includes a first mounting base 221, a first connecting member 222, and a suction cup 223. The first mounting base 221 is fixed to the end of the outer telescopic rod 110. The first connecting member 222 is slidably connected to the first mounting base 221. The suction cup 223 is fixedly connected to the first connecting member 222. The screw 212 is connected to the first connecting member 222. By rotating the inner telescopic rod 120, the screw 212 moves axially in the fixed base 211, thereby driving the first connecting member 222 to slide in the first mounting base 221. This causes the suction cup 223 to move towards or away from the lamp, enabling the suction cup 223 to adsorb or release the lamp, facilitating lamp gripping and improving lamp maintenance convenience.

[0032] In addition, the operator holds the outer telescopic rod 110 close to the lamp to allow the suction cup 223 to adhere to the lamp. Then, the operator rotates the inner telescopic rod 120 in the forward direction to expel the air between the suction cup 223 and the lamp. Then, the operator rotates the inner telescopic rod 120 in the reverse direction to move the suction cup 223 away from the lamp. This increases the vacuum between the suction cup 223 and the lamp, allowing the lamp to be stably attached to the suction cup 223. This facilitates stable installation and removal of the lamp, reduces the possibility of the lamp coming loose, and improves reliability.

[0033] It should be noted that the screw 212 and the first connecting member 222 can be threaded or rotatably connected, so that the first connecting member 222 can be relatively fixed in the axial direction of the screw 212, so that when the screw 212 moves along the axial direction of the fixed seat 211, the screw 212 can drive the first connecting member 222 to move synchronously along the axial direction in the first mounting seat 221, so that the suction cup 223 can adsorb or release the lamp.

[0034] The screw 212 may be provided with a locking block (not shown in the figure), and the first connecting member 222 is provided with a locking groove (not shown in the figure). The locking block is rotatably connected in the locking groove so that when the screw 212 moves axially, the locking block can abut against the inner wall of the locking groove, thereby driving the first connecting member 222 to move axially along the screw 212.

[0035] Specifically, refer to Figure 4 and Figure 5The first mounting base 221 is provided with a guide strip 224, and the first connector 222 has a guide groove 225, in which the guide strip 224 is arranged. The first mounting base 221 protrudes with the guide strip 224, and the first connector 222 has a guide groove 225. By setting the guide strip 224 in the guide groove 225, the first connector 222 can be guided to move along the length of the guide strip 224, effectively avoiding the first connector 222 from deviating or shaking during sliding. This makes the movement trajectory of the suction cup 223 accurate and stable, further improving the adhesion accuracy between the suction cup 223 and the lamp, enhancing the firmness of the adsorption, reducing the risk of the lamp falling and being damaged due to unstable adsorption during disassembly and assembly, and making the lamp disassembly and assembly operations more reliable.

[0036] It should be noted that multiple guide bars 224 and guide grooves 225 are provided, with each guide bar 224 corresponding to a different guide groove 225. The cooperation of multiple guide bars 224 and multiple guide grooves 225 improves the accuracy of the movement of the first connector 222 within the first mounting base 221, prevents positional misalignment of the suction cup 223, and enhances reliability.

[0037] Specifically, refer to Figures 6 to 8 The functional component 220 includes a second mounting base 226, a second connector 227, and a plurality of grippers 228. The second mounting base 226 is fixed to the end of the outer telescopic rod 110. The grippers 228 are all hinged to the second mounting base 226 and the second connector 227. The plurality of grippers 228 are arranged around the second mounting base 226. The screw 212 is connected to the second connector 227. The second mounting base 226 is fixed to the end of the outer telescopic rod 110. The grippers 228 are all hinged to the second mounting base 226 and the second connecting member 227. By rotating the inner telescopic rod 120, the screw 212 is driven to move axially in the fixed base 211, so that the screw 212 can drive the second connecting member 227 to move closer to or away from the second mounting base 226, so that the multiple grippers 228 can move closer to or further away from each other. This allows the multiple grippers 228 to cooperate in gripping or releasing the lamp, which can adapt to lamps of different shapes and sizes, improve the stability and reliability of gripping, effectively prevent the lamp from slipping and being damaged during disassembly and assembly, and improve the convenience of lamp maintenance.

[0038] It should be noted that the screw 212 and the second connector 227 can be threaded or rotatably connected so that the screw 212 and the second connector 227 are fixed relative to each other along the axial direction, so that when the screw 212 moves along the axial direction, it can drive the second connector 227 to move closer to or away from the second mounting base 226, thereby causing the multiple grippers 228 to clamp or loosen.

[0039] Specifically, refer to Figure 8The gripper 228 has an anti-slip pad 229 on its inner side, which can abut against the lamp fixture. By providing an anti-slip pad 229 on the inner side of the gripper 228 to abut against the lamp fixture, when multiple grippers 228 grip the lamp fixture, the anti-slip pad 229 can increase the friction between the gripper 228 and the surface of the lamp fixture, effectively preventing the lamp fixture from sliding or falling off due to external forces or its own weight during the gripping process, further improving the stability and reliability of the lamp fixture gripping, and reducing the risk of lamp fixture damage.

[0040] It should be noted that the anti-slip pad 229 can be an elastic component such as a rubber or silicone part, to absorb the stress between the gripper 228 and the lamp, reduce the possibility of lamp breakage, and improve reliability.

[0041] Understandably, referring to Figure 2 and Figure 3 The end of the first sleeve 111 is connected to a locking assembly 130. The locking assembly 130 includes a first locking block 131, a second locking block 132 and a wedge 133. The first locking block 131 is fixed to the end of the first sleeve 111. The second locking block 132 is threaded to the first locking block 132. The wedge 133 is fixed to the second locking block 132. The wedge 133 can extend between two adjacent first sleeves 111. The first locking block 131 is fixed to the end of the first sleeve 111. By setting the second locking block 132 to be threadedly connected to the first locking block 131, the second locking block 132 can move along the axial direction of the first locking block 131, so as to drive the wedge block 133 to extend into or withdraw between two adjacent first sleeves 111. The inclined structure of the wedge block 133 effectively restricts the relative sliding between the first sleeves 111, enhances the locking effect of the outer telescopic rod 110, and keeps the outer telescopic rod 110 stable after the extension and retraction adjustment. This avoids the lamp grab position shifting or falling due to the accidental extension and retraction of the outer telescopic rod 110, and improves the accuracy and safety of lamp disassembly and assembly operations.

[0042] Specifically, refer to Figure 2 and Figure 3 A stop 112 is provided at the end of the first sleeve 111 away from the locking assembly 130. The stop 112 can abut against the wedge 133 of the adjacent first sleeve 111. The stop 112 is fixedly connected to the end of the first sleeve 111 away from the locking assembly 130 so that when two adjacent first sleeves 111 slide relative to each other axially, the stop 112 can abut against the wedge 133, thereby limiting the extension and retraction position of the first sleeve 111, preventing the first sleeve 111 from dislodging, keeping the outer telescopic rod 110 stable, and improving reliability.

[0043] Specifically, refer to Figure 2 and Figure 9The second sleeve 121 is provided with a limiting part 122 and a limiting groove 123, which are respectively arranged on the inner and outer sides of the second sleeve 121. Two adjacent second sleeves 121 are slidably connected along the axial direction through the limiting part 122 and the limiting groove 123. The limiting part 122 of the first second sleeve 121 can extend into the limiting groove 123 of the second second sleeve 121, so that two adjacent second sleeves 121 can be guided to slide along the axial direction through the limiting part 122 and the limiting groove 123. The limiting part 122 is located in the limiting groove 123, which can lock the circumference of two adjacent second sleeves 121, so that multiple second sleeves 121 can rotate synchronously, improve the stability of operation, and prevent the position of the second sleeves 121 from shifting.

[0044] It should be noted that each second sleeve 121 has multiple limiting parts 122 and limiting grooves 123. The multiple limiting parts 122 are arranged at intervals along the circumference of the second sleeve 121, which not only enables the multiple second sleeves 121 to be locked along the circumference, but also enhances the load-bearing capacity of the inner telescopic rod 120 and improves reliability.

[0045] In addition, the limiting part 122 and the limiting groove 123 can be integrally formed on the second sleeve 121 by extrusion, which improves the structural stability of the inner telescopic rod 120 and reduces the possibility of bending deformation.

[0046] The limiting part 122 and the limiting groove 123 are both designed to be arc-shaped to reduce stress concentration in the second sleeve 121 and reduce the possibility of deformation failure of the inner telescopic rod 120.

[0047] Specifically, refer to Figure 2 A knob 113 is rotatably connected to the end of the outer telescopic rod 110 furthest from the functional component 220. The knob 113 is fixedly connected to the inner telescopic rod 120. Rotating the knob 113 directly drives the inner telescopic rod 120 to rotate, eliminating the need for direct contact with the inner telescopic rod 120. This avoids operational inconvenience caused by hand slippage or limited space, making the rotation control of the inner telescopic rod 120 more convenient and effortless, and improving the comfort and efficiency of the lamp assembly / disassembly device.

[0048] In addition, the other end of the inner telescopic rod 120 is connected to the fixed base 211 via the knob 113, so that the other end of the outer telescopic rod 110 and the other end of the inner telescopic rod 120 are fixed relative to each other along the axial direction, so that the outer telescopic rod 110 and the inner telescopic rod 120 can extend and retract synchronously.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
