Description

Technical Field

[0001] The invention relates to the technical field of auxiliary lighting devices, and in particular to an energy-saving lighting system for multi-head shadowless equipment maintenance. Background Art

[0002] Multi-head shadowless equipment usually refers to multi-head shadowless lamps, which are a type of lighting equipment widely used in medical operating rooms. This type of equipment needs to be powered off during maintenance, so additional auxiliary lighting devices are needed for lighting to facilitate equipment maintenance and installation operations. The auxiliary lighting device can be clamped and fixed in any position through the connecting clamp at the bottom for use, and the lighting position can be freely adjusted and selected.

[0003] However, with regard to the currently available multi-head shadowless equipment maintenance auxiliary lighting device, the connecting clamp at the bottom is generally achieved by the clamping and locking force provided by an elastic member (such as a spring). This locking force is flexible, and it is easy for the clamp to loosen and cause the auxiliary lighting device to fall in the event of an external accidental collision. The stability is poor, and the clamp is generally a scissor-type opening structure. When clamping and positioning on a thicker plate, the clamping stability is not high due to the small clamping surface, and the practicality is poor. Summary of the invention

The maintenance lighting fixture 101 can adjust the use angle by the locking bolt 104. When the locking bolt 104 is loosened, the upper support arm 102 can rotate on the top of the lower support 103 to change the use position, thereby changing the use angle of the maintenance lighting fixture 101. After the adjustment is completed, the locking bolt 104 can be tightened again, which is convenient for adjustment. It also includes a connecting assembly, which is composed of a clamping mechanism 2 and a multi-control mechanism 3; The clamp mechanism 2 includes a fixed seat 201, a positioning plate 202 and two fixed clamps 203. The bottom of the lower support 103 is fixedly mounted on the top of the fixed seat 201, and the positioning plate 202 is plugged into the inside of the fixed seat 201. The fixed clamps 203 are plugged into the inside of the fixed seat 201, and the two fixed clamps 203 are symmetrical to each other. The multi-control mechanism 3 includes a main control rod 301, a switching rod 302, a linkage seat 303, a control block 304 and a sub-control ring 305. The main control rod 301 is inserted into the interior of the fixed seat 201, and one end of the main control rod 301 is rotatably connected to the side of the positioning plate 202, the switching rod 302 is rotatably connected to the interior of the main control rod 301, and the linkage seat 303 is axially inserted into the interior of the main control rod 301, the control block 304 is radially inserted into the interior of the main control rod 301, the sub-control ring 305 is rotatably connected to the outside of the main control rod 301, and the switching rod 302 and the sub-control ring 305 are connected by a gear rack transmission.

[0031] In the embodiment of the present disclosure, a rubber anti-skid pad 2031 is provided at the bottom of the fixed clamp 203, and an inclined clamp release groove 2021 is provided inside the plate body of the positioning plate 202, and a clamp release rod 2032 is provided on the inner side of the fixed clamp 203, and the clamp release rod 2032 is inserted into the clamp release groove 2021. The rubber anti-skid pad 2031 can increase the friction force for clamping and fixing, and can also generate deformation to buffer the clamping and fixing force when the connecting component is in the rigid locking mode, thereby avoiding damage to the device as the clamping and fixing force increases.

[0032] In the embodiment of the present disclosure, a clamping tension spring 2022 is provided on the side of the positioning plate 202, and the two ends of the clamping tension spring 2022 are respectively fixedly connected to the side of the positioning plate 202 and the inside of the fixing seat 201. Under the action of the clamping tension spring 2022, when the positioning plate 202 is not resisted by external force, the two fixing clamps 203 are in a closed state. In use, when the multi-control mechanism 3 is in the reset state (the auxiliary control ring 305 is not rotated by external force), the connecting component is in a flexible locking mode, and the control protrusion 3031 is in the driving position. The threaded block 3042 will not be threadedly engaged with the locking threaded groove 2011, and the threaded block 3042 will not hinder the movement of the main control rod 301 inside the fixing seat 201. At the same time, under the action of the clamping tension spring 2022, the two fixing clamps 203 are in a closed state (i.e., the minimum use spacing). When the connecting component needs to be clamped and fixed on the plate body at a suitable position for fixing, the main control rod 301 only needs to be pressed to control the two fixing clamps The clamps 203 are opened and inserted into the edge position of the plate body. After that, the main control rod 301 is loosened and the two fixed clamps 203 can automatically close and fix the connecting component and the lighting component 1 in the corresponding position for lighting use. The operation is convenient and flexible. In the flexible locking mode, when the main control rod 301 is pressed, the main control rod 301 can drive the positioning plate 202 to move synchronously and lengthen the clamping tension spring 2022. When the positioning plate 202 moves, the loose clamp groove 2021 can drive the fixed clamp 203 to move linearly through the loose clamp rod 2032. The main control rod 301 is automatically opened, thereby facilitating the operation of inserting it into the edge of the plate body. After that, after loosening the main control rod 301, under the action of the clamping tension spring 2022, the positioning plate 202 will drive the main control rod 301 to synchronously move in the opposite direction and reset until the two fixed clamps 203 are clamped on both sides of the plate body, and the positioning and installation operation of the lighting assembly 1 is completed. In the flexible locking mode, the clamping tension spring 2022 is elastically locked, and the opening and closing of the fixed clamp 203 is smooth and fast, and it is easy to use and suitable for quick installation and disassembly at high places or locations that are not easily collided.

[0033] In the embodiment of the present disclosure, a switching groove is provided on the outside of the rod body of the switching rod 302, and a control protrusion 3031 is provided on the inside of the linkage seat 303, and the control protrusion 3031 is inserted into the inside of the switching groove. The switching groove is composed of a spirally arranged driving groove 3021 and an arc-shaped locking groove 3022, and the locking groove 3022 and the driving groove 3021 are connected end to end. A locking thread groove 2011 is provided on the inside of the fixed seat 201, and a thread block 3042 is provided on the top of the control block 304. When the control protrusion 3031 is located inside the driving groove 3021 and away from one end of the locking groove 3022, the thread block 3042 will not be threaded with the locking thread groove 2011. When the control protrusion 3031 is located inside the locking groove 3022, the thread block 3042 is threadedly matched with the locking thread groove 2011. In use, when the lighting assembly 1 needs to be installed and used in a rigid locking mode, the lighting assembly 1 is first quickly positioned to a suitable position through the connecting assembly in a flexible locking mode, and then the auxiliary control ring 305 is rotated forward to achieve the rigid locking of the connecting assembly and the plate body, so as to avoid the lighting assembly 1 from accidentally falling and being damaged due to external collision. The use is stable. When the connecting assembly is clamped and fixed to the edge of the plate body through the flexible locking mode and the auxiliary control ring 305 is rotated forward, the auxiliary control ring 305 can The switch rod 302 is driven to rotate by the gear rack. When the switch rod 302 rotates, the driving groove 3021 can drive the linkage seat 303 to move to one side through the control protrusion 3031 and compress the reset top spring 3032. The top of the linkage seat 303 is provided with an inclined linkage groove 3033, and the control block 304 is provided with a linkage rod 3041 inside. The linkage rod 3041 is inserted into the linkage groove 3033. When the linkage seat 303 moves, the linkage groove 3033 can drive the control block 304 to move upward through the linkage rod 3041, so that the threaded block 3042 and the locking threaded groove 2011 are threadedly matched, and then the control protrusion 3031 enters the lock The inside of the fixed groove 3022, when the auxiliary control ring 305 continues to rotate, the auxiliary control ring 305 can drive the main control rod 301 to rotate synchronously through the interference between one end of the locking groove 3022 and the control protrusion 3031. When the main control rod 301 rotates, under the action of the threaded cooperation between the thread block 3042 and the locking thread groove 2011, the main control rod 301 can move in the internal threaded manner of the fixed seat 201 to adjust the locking force between the two fixed clamps 203. Since the threaded transmission has the characteristic of one-way transmission, the rigid locking use between the connecting component and the edge of the plate body is realized, and the installation positioning of the lighting component 1 is stable and flexible to use.

[0034] In the disclosed embodiment, a return spring 3032 is provided on the side of the linkage seat 303, and the two ends of the return spring 3032 respectively abut against the side of the linkage seat 303 and the inside of the main control rod 301. During use, when the connecting assembly is in a rigid locking state for installation and use, if the connecting assembly needs to be removed from the edge of the plate body, it is only necessary to reverse the auxiliary control ring 305. When the auxiliary control ring 305 is reversed, the control protrusion 3031 will re-enter the inside of the driving groove 3021 from the locking groove 3022. Therefore, under the action of the return spring 3032, the control protrusion 3031 will always be located inside the driving groove 3021 and away from one end of the locking groove 3022. Thereafter, the two fixed clamps 203 can be quickly opened by pressing the main control rod 301. No matter what use mode the connecting assembly is in, the quick disassembly operation can be achieved, which is flexible and convenient to use.

[0035] Specific usage and function of this embodiment: In the present invention, firstly, the use angle of the maintenance lighting fixture 101 is adjusted to adapt to the lighting use during maintenance. The maintenance lighting fixture 101 can adjust the use angle by means of the locking bolt 104. When the locking bolt 104 is loosened, the upper support arm 102 can rotate on the top of the lower support 103 to change the use position, thereby changing the use angle of the maintenance lighting fixture 101. After the adjustment is completed, the locking bolt 104 can be tightened again. After the adjustment is completed, the lighting assembly 1 can be installed on a fixed plate body (the plate body referred to in this embodiment refers to all connecting plates with which the connecting assembly can realize the clamping and fixing action) at a suitable position through the connecting assembly. The multi-control mechanism 3 is in the reset state (the auxiliary control ring 305 When the locking cam 3021 is in the state of being rotated without external force, the connecting component is in the flexible locking mode, and the control protrusion 3031 is located inside the driving groove 3021 and away from one end of the locking groove 3022, so that the threaded block 3042 will not be threadedly matched with the locking threaded groove 2011, and the threaded block 3042 will not hinder the movement of the main control rod 301 inside the fixing seat 201. At the same time, under the action of the clamping tension spring 2022, the two fixing clamps 203 are in a closed state (i.e., the minimum usage spacing). When it is necessary to clamp the connecting component on the plate body in a suitable position for fixing, it is only necessary to press the main control rod 301 to control the two fixing clamps 203 to open and insert them into the edge position of the plate body. After that, the two fixing clamps 203 are released after the main control rod 301 is released. The clamp 203 can automatically close and fix the connecting component and the lighting component 1 in the corresponding position for lighting use. It is easy to operate and flexible to use. In the flexible locking mode, when the main control rod 301 is pressed, the main control rod 301 can drive the positioning plate 202 to move synchronously and lengthen the clamping tension spring 2022. When the positioning plate 202 moves, the loose clamp groove 2021 can drive the fixed clamp 203 to move linearly and open through the loose clamp rod 2032, thereby facilitating the operation of inserting it into the edge position of the plate body. After that, after the main control rod 301 is released, under the action of the clamping tension spring 2022, the positioning plate 202 will drive the main control rod 301 to move synchronously in the opposite direction and reset until the two fixed clamps 203 are clamped on both sides of the plate body, and the positioning and installation of the lighting component 1 is completed. During installation and operation, the flexible locking mode is elastically locked by the clamping tension spring 2022, and the opening and closing of the fixed clamp 203 is smooth and fast, which is suitable for quick installation and disassembly at high places or places that are not easily collided. When the lighting assembly 1 needs to be installed and used through the rigid locking mode, the lighting assembly 1 is first quickly positioned to a suitable position through the connecting assembly through the flexible locking mode, and then the rigid locking of the connecting assembly and the plate body can be achieved by positively rotating the auxiliary control ring 305, so as to avoid the phenomenon that the lighting assembly 1 accidentally falls and is damaged due to external collision. It is stable to use. After the connecting assembly is clamped and fixed to the edge of the plate body through the flexible locking mode and the auxiliary control ring 305 is rotated forward, the auxiliary control ring 305 can drive the switching rod 302 to rotate through the gear rack.When the switching rod 302 rotates, the driving groove 3021 can drive the linkage seat 303 to move to one side and compress the reset top spring 3032 through the control protrusion 3031. When the linkage seat 303 moves, the linkage groove 3033 can drive the control block 304 to move upward through the linkage rod 3041, so that the thread block 3042 and the locking thread groove 2011 are threadedly engaged, and then the control protrusion 3031 enters the interior of the locking groove 3022. When the auxiliary control ring 305 continues to rotate, the auxiliary control ring 305 can drive the main control rod 301 to rotate synchronously through the interference between one end of the locking groove 3022 and the control protrusion 3031. When the main control rod 301 rotates, under the action of the threaded engagement between the thread block 3042 and the locking thread groove 2011, the main control rod 301 can move in a threaded manner inside the fixed seat 201, thereby The locking force between the two fixed clamps 203 is regulated. Since the threaded transmission has the characteristic of one-way transmission, the rigid locking between the connecting component and the edge of the plate body is realized. The installation and positioning of the lighting component 1 is stable. When the connecting component is in rigid locking for installation, if the connecting component needs to be removed from the edge of the plate body, it is only necessary to reverse the auxiliary control ring 305. When the auxiliary control ring 305 is reversed, the control protrusion 3031 will re-enter the driving groove 3021 from the locking groove 3022. Therefore, under the action of the reset top spring 3032, the control protrusion 3031 will always be located inside the driving groove 3021 and away from one end of the locking groove 3022. After that, the two fixed clamps 203 can be quickly opened by pressing the main control rod 301. No matter what use mode the connecting component is in, the quick disassembly operation can be realized.
