Description

Technical Field

[0001] The utility model relates to the technical field of lighting appliances, and more specifically to an ultra-narrow track head structure. Background Art

[0002] Track lights are common lighting appliances in our daily lives, including lamps, track heads and tracks. The tracks are used to fix the track heads, and the track heads are used to install lamps. In the prior art, the track heads must be installed and fixed to both the lamps and the tracks. Components that are installed and fixed to the lamps and tracks need to be set inside the track head structure, making the track head structure complex, with many parts and components, and the overall structure is relatively heavy. In addition, the driving components of some track lights are also set inside the track head, further increasing the internal space and overall width of the track head.

[0003] Since the main shell of the rail head is thicker and wider, the width of the rail used to fix the rail head is correspondingly larger, which increases the production and transportation costs. The wider rail requires a wider installation area on the ceiling or wall, which affects the aesthetics of the decoration and increases the difficulty of installation and fixation.

[0004] CN217273995U discloses an ultra-thin magnetic track light, comprising a housing, an LED light board installed inside the housing; a guide block, arranged at the bottom of the housing and embedded in the slide groove on the track plate; a conductive block, arranged at the bottom of the housing and embedded in the slide groove on the track plate and in contact with the slide groove; a pressing block, arranged at both sides of the housing and movable toward each other, a buckle plate arranged at the bottom of the pressing block, the buckle plate buckles with the side wall of the slide groove on the track plate, and a first elastic member is arranged between the pressing blocks.

In the utility model, the lamp body can be easily disassembled by setting the fixed strip and the shell slide groove, the fixed strip and the shell slide groove are hidden inside the guide rail mounting shell, which can well protect the track structure, and combined with the design of the conductive module and the lamp body, the track can be made very thin, light, low cost, and beautiful.

[0006] CN217302566U discloses an ultra-thin concealed magnetic track light assembly, including an upper shell, a movable slot is provided at the top of the upper shell, a movable block is connected to the inner cavity of the movable slot, one end of the movable block is connected to a fixed spring, one end of the fixed spring is connected to the fixed block, a movable plate is provided on the other side of the upper shell, a movable bolt is provided on one side of the movable plate, a first slot is provided on both sides of the inner cavity of the upper shell, a first plug-in plate is connected to the inner cavity of the first slot, a conductive slot is provided on one side of the first plug-in plate, a conductive plate is provided in the inner cavity of the conductive slot, a first connecting slot is provided at the top of the inner cavity of the upper shell, a magnetic plate is provided in the inner cavity of the first connecting slot, a lower shell is provided in the inner cavity of the upper shell, and a second plug-in plate is provided at the bottom of the inner cavity of the upper shell. The utility model solves the problem that the existing magnetic track lights are generally installed directly by magnetic attraction and buckles, and rely on copper wires to conduct electricity to the lamps, and the position of the lamps cannot be moved at will.

[0007] Although the above utility models are all called ultra-thin track lights, the track head structure is still complicated, with many parts and components, and the overall structure is relatively heavy. It mainly solves the problem of installation and fixation, and can only reduce the width of the track head and the track to a certain extent, but cannot significantly reduce the width of the track head and the track. Utility Model Content

[0008] The utility model aims to solve the above technical problems at least to a certain extent.

[0009] The utility model aims to provide an ultra-narrow rail head structure with simple structure and beautiful appearance.

[0010] The technical solution adopted by the utility model to solve its technical problems is: an ultra-narrow rail head structure, including a shell and a rectifier plate, the rectifier plate is arranged in the shell, and conductive openings and elastic fasteners are respectively provided on both sides of the shell, conductive blocks are respectively provided on both sides of the rectifier plate, and the conductive blocks are stuck in the conductive openings, and a sliding component and a fixing assembly are provided at the bottom of the shell, the sliding component includes a first slide groove and a sliding member, the sliding member is slidably fixed to the first slide groove, the sliding member includes a sliding part and an abutting part, the sliding part can slide relative to the first slide groove so that the abutting part abuts or disengages from the elastic fastener, the fixing assembly includes a fixing seat, a fixing block and a fixing member, the fixing seat is arranged at the bottom of the shell, the fixing block is fixed to the fixing seat, and the fixing member is relatively fixed to the fixing block.

[0011] When the utility model is installed and fixed with the track, it is only necessary to slide the sliding part relative to the first slide groove so that the abutting part is separated from the elastic fastener on the inner side of the elastic fastener, and the elastic fastener is in an unlocked state. Then, the elastic fasteners on both sides of the shell are clamped into the track by external force, and the elastic fasteners can be buckled with the hooks of the track. After buckling, the sliding part is slid relative to the first slide groove so that the abutting part abuts against the elastic fastener on the inner side of the elastic fastener. The elastic fastener is abutted and cannot produce elastic deformation, that is, it is in a locked state, and the track head cannot be removed from the track by external force. After installation, the conductive blocks on both sides are in direct contact with the conductive elements of the track to achieve electrical connection between the track head and the track.

[0012] When the utility model is disassembled from the track, it is only necessary to slide the sliding part relative to the first sliding groove so that the abutting part is separated from the elastic fastener inside the elastic fastener, and the elastic fastener is in an unlocked state again. By pulling the track head outward with external force, the elastic fastener is squeezed by the external force and slowly shrinks inward, and finally separates from the hook of the track, so that the track head can be completely removed from the track.

[0013] When the utility model is installed and fixed to the lamp, it can be installed by directly fixing the fixing piece at the bottom of the shell to the fixing structure adapted to the lamp. After installation, the electrical connection between the track head and the lamp can be achieved by connecting the wire through the fixing piece and the conductive element of the lamp or by directly contacting the conductive element of the lamp as a conductive accessory.

[0014] When the utility model is disassembled from the lamp, it only needs to directly unlock the fixing piece at the bottom of the shell and the fixing structure matched with the lamp to realize disassembly.

[0015] The utility model can realize installation, fixing and disassembly with the track by using the elastic fasteners on both sides of the shell and the sliding parts at the bottom of the shell, and can realize installation, fixing and disassembly with the lamp by using the fixing components at the bottom of the shell. Therefore, only an ultra-thin rectifier plate needs to be set inside the shell, eliminating the components that are installed and fixed with the lamp and the track respectively, and also eliminating other non-essential parts such as the driver, thereby greatly reducing the width of the shell. Since the shell of the track head is ultra-narrow, the corresponding track width is also greatly reduced. The ultra-narrow track and ultra-narrow track head can greatly reduce the production and transportation costs, and occupy very little area and space, greatly improving the aesthetics of the decoration.

[0016] In a preferred embodiment, the shell includes a first shell and a second shell, the edge of the first shell is provided with a slot, the edge of the second shell is provided with a strip, and the strip can be inserted into the slot. Since only an ultra-thin rectifier plate needs to be arranged inside the shell, the space and width required inside are extremely small. If the shell is formed in one piece, it is likely to increase the internal space due to the process, resulting in waste of internal space, thereby increasing the overall width. The shell is split into a first shell and a second shell, and the first shell and the second shell can be made into ultra-narrow sheets at the same time. The first shell and the second shell press the rectifier plate between them, and then engage with each other through the strip and the slot, which can avoid waste of internal space to the greatest extent, thereby reducing the overall width of the shell.

[0017] More preferably, the bottom ends of the first housing are provided with positioning grooves, and the bottom ends of the second housing are provided with positioning blocks, which can be inserted into the positioning grooves. The first housing and the second housing can be quickly fixed by the positioning blocks and the positioning grooves.

[0018] More preferably, the first shell and the second shell are both made of plastic material, and the first shell and the second shell are sealed at least by ultrasonic welding. Ultrasonic welding has high speed, high welding strength and good sealing, and is suitable for ultra-thin structure processing.

[0019] In a preferred embodiment, a fixing groove is provided at the end of the rectifier plate, a fixing hook is provided at one end of the conductive block, the fixing hook is inserted into the fixing groove, and a conductive sheet is provided at the other end of the conductive block, the conductive sheet is bent and inserted into the conductive opening and protrudes from the shell. The rectifier plate and the conductive block are fixed and electrically connected by the fixing hook being inserted into the fixing groove, and the conductive sheet is bent and inserted into the conductive opening and protrudes from the shell, so that it can directly contact the conductive element of the track to achieve electrical connection with the track. The conductive block is integrally formed, one end is bent to form a fixing hook, and the other end is bent to form a conductive sheet, and the structure is simple.

[0020] In a preferred embodiment, the housing is provided with a second slide slot, the second slide slot is parallel to the first slide slot, the abutting portion is cross-shaped and is provided with a first leg and a second leg, the abutting portion is connected to the sliding portion through the first leg, the first leg is clamped in the first slide slot, the second leg is perpendicular to the first leg, and the second leg is clamped in the second slide slot. When in use, the sliding portion is pushed to slide left and right, the first leg moves left and right in the first slide slot, and the second leg slides left and right along the second slide slot, thereby achieving the abutting portion abutting or disengaging from the elastic fastener.

[0021] In a preferred embodiment, the width of the fixing seat and the fixing block is greater than that of the outer shell, the fixing block is provided with a fixing shell, the fixing shell is provided with a fixing cavity, the fixing shell covers the fixing seat and accommodates the fixing seat in the fixing cavity, the two ends of the fixing seat are respectively provided with fixing columns, the fixing columns are provided with a first fixing hole, the two ends of the fixing shell are respectively provided with a second fixing hole, the first fixing hole is aligned with the second fixing hole and is fixed by a first fastener. Since the outer shell is thin as a whole, the overall strength of the structure may be insufficient, so the width of the fixing seat and the fixing block is designed to be greater than the outer shell to increase the installation force area, which is convenient for installing and fixing the lamp, and can also increase the overall strength of the structure to ensure that it is installed and fixed with the lamp more firmly. In addition, adding a structure of a fixing block and providing fixing columns at both ends of the fixing seat can further improve the overall strength of the structure and further increase the stability of the fixation.

[0022] More preferably, a third fixing hole is provided in the middle of the second fixing hole, the fixing member comprises a fixing head and a fixing rod, the fixing head is wider than the third fixing hole, the fixing rod is narrower than the third fixing hole, the fixing head is located in the fixing cavity and abuts against the fixing seat, and the fixing rod passes through the third fixing hole. The fixing rod is used to directly fix with the fixing structure adapted to the lamp, so that the lamp can be installed.

[0023] More preferably, a rotating circle is provided between the fixing seat and the fixing member, the fixing head is in contact with the fixing seat through the rotating circle, a first limit block is provided on the end face of the fixing head, the first limit block is located in the rotating circle and can rotate in the rotating circle, a second limit block is provided on the inner wall of the rotating circle, a third limit block is provided on the outer wall of the rotating circle, and the third limit block is limited by the inner wall of the fixing shell. The rotating circle facilitates the fixing member to rotate relative to the fixing seat and the fixing block, thereby enabling the lamp to rotate relative to the fixing seat and the fixing block, and facilitating the adjustment of the lighting angle of the lamp.

[0024] When the lamp is rotated, the lamp drives the fixing member to rotate together, and the first limit block of the fixing member rotates in the rotating circle along the inner wall of the rotating circle. The first limit block can rotate from one side of the second limit block to the other side of the second limit block, which is called the first rotation stroke. The first rotation stroke is equal to 360° minus the angle occupied by the first limit block and the second limit block, which is close to 360°.

[0025] Then, the first limit block continues to push the second limit block from the other side of the second limit block to rotate together, thereby driving the rotating circle to rotate together, and the third limit block located on the outer wall of the rotating circle also rotates together, and can rotate from the inner wall of one side of the fixed shell to the inner wall of the other side of the fixed shell. Since the second limit block, the third limit block and the rotating circle are integrated, the rotation stroke of the second limit block is equal to the rotation stroke of the third limit block, and also equal to the rotation stroke of the rotating circle, which is called the second rotation stroke. The second rotation stroke is equal to the angle of the third limit block rotating from the inner wall of one side of the fixed shell to the inner wall of the other side of the fixed shell.

[0026] Therefore, the rotation angle of the first limit block is equal to the sum of the first rotation stroke and the second rotation stroke. Since the width and angle between the inner walls on both sides of the fixed shell are greater than the width and angle of the first limit block and the second limit block, the total rotation angle of the first limit block can exceed 360°. Therefore, the fixing member can be rotated arbitrarily within the range of 360°, and then the lamp can be rotated arbitrarily within the range of 360°, which is convenient for adjusting the lighting angle of the lamp.

[0027] More preferably, at least one end of the fixed seat is provided with an arc-shaped wall, and the arc-shaped wall and the inner wall of the fixed shell jointly limit the rotational travel of the rotating circle, and the third limit block can rotate along the arc-shaped wall. Since the fixing member and the rotating circle itself are light in weight, they may shift or make non-directional movements during the rotation process, resulting in rotation jamming or the entire structure being misplaced and unable to be used normally. Since the third limit block can only rotate between the inner walls of the fixed shell at one end, an arc-shaped wall is provided at the corresponding end of the fixed seat, and the arc-shaped wall and the inner wall of the fixed shell jointly limit the rotational travel of the rotating circle, which plays a role of limiting and directing, ensuring that the rotating circle can stably rotate within the rotational travel and can be used for a long time and reliably. In addition, the arc-shaped wall is a rib-shaped structure, which can also increase the structural strength of the fixed seat.

[0028] More preferably, arc-shaped walls are provided at both ends of the fixing seat, so that the third limiting block can rotate stably no matter which end it is arranged at, and the structural strength of the fixing seat is further increased.

[0029] The beneficial effects of the utility model are as follows: the utility model can realize installation, fixing and disassembly with the track by using the elastic fasteners on both sides of the shell and the sliding parts at the bottom of the shell, and can realize installation, fixing and disassembly with the lamp by using the fixing components at the bottom of the shell. Therefore, only an ultra-thin rectifier plate needs to be set inside the shell, eliminating the components that are installed and fixed with the lamp and the track respectively, and also eliminating other non-essential parts such as the drive, thereby greatly reducing the width of the shell. Since the shell of the track head is ultra-narrow, the corresponding track width is also greatly reduced. The ultra-narrow track and ultra-narrow track head can greatly reduce the production and transportation costs, and occupy very little area and space, greatly improving the aesthetics of the decoration.

For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. DETAILED DESCRIPTION

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] like Figures 1 to 13 As shown, an ultra-narrow rail head structure 100 of the utility model comprises a housing and a rectifying plate 101, wherein the rectifying plate 101 is arranged in the housing.

[0046] Conductive openings 102 and elastic fasteners 103 are respectively provided on two sides of the housing, and conductive blocks 104 are respectively provided on two sides of the rectifier plate 101 , and the conductive blocks 104 are snapped into the conductive openings 102 .

[0047] A sliding component is provided at the bottom of the housing, and the sliding component includes a first slide groove 105 and a sliding member 106, and the sliding member 106 is slidably fixed with the first slide groove 105. The sliding member 106 includes a sliding portion 107 and an abutting portion 108, and the sliding portion 107 can slide relative to the first slide groove 105 so that the abutting portion 108 abuts against or disengages from the elastic fastener 103.

[0048] A fixing assembly is provided at the bottom of the housing, and the fixing assembly includes a fixing seat 109 , a fixing block 110 and a fixing member 111 . The fixing seat 109 is provided at the bottom of the housing, the fixing block 110 is fixed to the fixing seat 109 , and the fixing member 111 is relatively fixed to the fixing block 110 .

[0049] When the utility model is installed and fixed with the track, it is only necessary to slide the sliding part 107 relative to the first slide groove 105 so that the abutting part 108 is separated from the elastic fastener 103 on the inner side of the elastic fastener 103, and the elastic fastener 103 is in an unlocked state. Then, the elastic fasteners 103 on both sides of the shell are clamped into the track by external force, and the elastic fasteners 103 can be buckled with the hooks of the track. After buckling, the sliding part 107 is slid relative to the first slide groove 105 so that the abutting part 108 abuts against the elastic fastener 103 on the inner side of the elastic fastener 103, and the elastic fastener 103 is abutted and cannot produce elastic deformation, that is, it is in a locked state, and the track head cannot be removed from the track by external force. After installation, the conductive blocks 104 on both sides are in direct contact with the conductive elements of the track to achieve electrical connection between the track head and the track.

[0050] When the utility model is disassembled from the track, it is only necessary to slide the sliding part 107 relative to the first sliding groove 105 so that the abutting part 108 is separated from the elastic fastener 103 inside the elastic fastener 103, and the elastic fastener 103 is in the unlocked state again. By pulling the track head outward with external force, the elastic fastener 103 is squeezed by the external force and slowly shrinks inward, and finally separates from the hook of the track, so that the track head can be completely disassembled from the track.

[0051] When the utility model is installed and fixed to the lamp, it is only necessary to directly fix the fixing piece 111 at the bottom of the housing to the fixing structure adapted to the lamp to achieve installation. After installation, the electrical connection between the track head and the lamp can be achieved by connecting the wire through the fixing piece 111 to the conductive element of the lamp or by directly contacting the conductive element of the lamp as a conductive accessory.

[0052] When the utility model is disassembled from the lamp, it is only necessary to directly unlock the fixing member 111 at the bottom of the shell and the fixing structure adapted to the lamp to achieve disassembly.

[0053] The utility model can realize installation, fixing and disassembly with the track by using the elastic fasteners 103 on both sides of the shell and the sliding parts at the bottom of the shell, and can realize installation, fixing and disassembly with the lamp by using the fixing components at the bottom of the shell. Therefore, only an ultra-thin rectifier plate 101 needs to be set inside the shell, eliminating the components that are installed and fixed with the lamp and the track respectively, and also eliminating other non-essential parts such as the driver, thereby greatly reducing the width of the shell. Since the shell of the track head is ultra-narrow, the corresponding track width is also greatly reduced. The ultra-narrow track and ultra-narrow track head can greatly reduce the production and transportation costs, and occupy very little area and space, greatly improving the aesthetics of the decoration.

[0054] In this embodiment, sliding parts are provided at both ends of the bottom of the housing, and the sliding parts at both ends are symmetrically arranged, which can make the fixed installation between the rail head and the rail more stable. When in use, the sliding parts at both ends slide towards each other (slide to the middle) and the sliding part 107 is in a locked state, and slide away from each other (slide to both ends) and the sliding part 107 is in an unlocked state, which is convenient and reliable to use.

[0055] In this embodiment, the shell includes a first shell 112 and a second shell 113, the edge of the first shell 112 is provided with a card slot 114, and the edge of the second shell 113 is provided with a card strip 115, and the card strip 115 can be inserted into the card slot 114. Since only an ultra-thin rectifier plate 101 needs to be arranged inside the shell, the space and width required inside are extremely small. If the shell is formed in one piece, it is likely to increase the internal space due to the process, resulting in waste of internal space, thereby increasing the overall width. The shell is split into a first shell 112 and a second shell 113, and the first shell 112 and the second shell 113 can be made into ultra-narrow sheets at the same time. The first shell 112 and the second shell 113 press the rectifier plate 101 between them, and then achieve engagement through the card strip 115 and the card slot 114, which can avoid waste of internal space to the greatest extent, thereby reducing the overall width of the shell.

[0056] In this embodiment, two ends of the bottom of the first housing 112 are provided with positioning grooves 116, and two ends of the bottom of the second housing 113 are provided with positioning blocks 117, which can be inserted into the positioning grooves 116. The first housing 112 and the second housing 113 can be quickly fixed together by the positioning blocks 117 and the positioning grooves 116.

[0057] In this embodiment, the first shell 112 and the second shell 113 are both made of plastic material, and the first shell 112 and the second shell 113 are sealed at least by ultrasonic welding to seal the card strip 115 and the card slot 114. Ultrasonic welding has a high speed, high welding strength, and good sealing, and is suitable for ultra-thin structure processing. Considering the processing technology requirements of the shell material and the structural strength required by the material, the overall thickness of the shell of the utility model can be 3.6 mm, which is much lower than the same type of products in the prior art.

[0058] In this embodiment, a fixing groove 118 is provided at the end of the rectifier plate 101, a fixing hook 119 is provided at one end of the conductive block 104, and the fixing hook 119 is inserted into the fixing groove 118. A conductive sheet 120 is provided at the other end of the conductive block 104, and the conductive sheet 120 is bent and inserted into the conductive opening 102 and protrudes from the housing. The rectifier plate 101 and the conductive block 104 are fixed and electrically connected by the fixing hook 119 being inserted into the fixing groove 118, and the conductive sheet 120 is bent and inserted into the conductive opening 102 and protrudes from the housing, so that it can directly contact the conductive element of the track to achieve electrical connection with the track. The conductive block 104 is integrally formed, one end is bent to form the fixing hook 119, and the other end is bent to form the conductive sheet 120, and the structure is simple.

[0059] In this embodiment, the housing is provided with a second slide groove 121, and the second slide groove 121 is parallel to the first slide groove 105. The abutting portion 108 is cross-shaped and is provided with a first leg 122 and a second leg 123, and the abutting portion 108 is connected to the sliding portion 107 through the first leg 122. The first leg 122 is clamped in the first slide groove 105, and the second leg 123 is perpendicular to the first leg 122, and the second leg 123 is clamped in the second slide groove 121. When in use, the sliding portion 107 is pushed to slide left and right, and the first leg 122 moves left and right in the first slide groove 105, and the second leg 123 slides left and right along the second slide groove 121, thereby realizing that the abutting portion 108 abuts against or disengages from the elastic fastener 103.

[0060] In this embodiment, the width of the fixing seat 109 and the fixing block 110 is greater than the housing. Since the housing is thin as a whole, the overall strength of the structure may be insufficient, so the width of the fixing seat 109 and the fixing block 110 is designed to be greater than the housing to increase the installation force area, which is convenient for installing and fixing the lamp, and can also increase the overall strength of the structure to ensure that the lamp is installed and fixed more firmly.

[0061] The fixing block 110 is provided with a fixing shell 124, and a fixing cavity 125 is provided in the fixing shell 124. The fixing shell 124 covers the fixing seat 109 and accommodates the fixing seat 109 in the fixing cavity 125. The fixing seat 109 is provided with fixing columns 126 at both ends, and the fixing columns 126 are provided with first fixing holes 127. The fixing shell 124 is provided with second fixing holes 128 at both ends. The first fixing holes 127 are aligned with the second fixing holes 128 and are fixed by first fasteners (not shown). Adding the structure of the fixing block 110 and the fixing columns 126 at both ends of the fixing seat 109 can further improve the overall strength of the structure and further increase the stability of the fixation.

[0062] In this embodiment, a third fixing hole 129 is provided in the middle of the second fixing hole 128. The fixing member 111 includes a fixing head 130 and a fixing rod 131, wherein the width of the fixing head 130 is greater than the third fixing hole 129, and the width of the fixing rod 131 is less than the third fixing hole 129. The fixing head 130 is located in the fixing cavity 125 and abuts against the fixing seat 109, and the fixing rod 131 passes through the third fixing hole 129. The fixing rod 131 is used to be directly fixed to the fixing structure adapted to the lamp, so that the lamp can be installed.

[0063] In this embodiment, a rotating circle 132 is provided between the fixing seat 109 and the fixing member 111, and the fixing head 130 abuts against the fixing seat 109 through the rotating circle 132. A first limiting block 133 is provided on the end surface of the fixing head 130, and the first limiting block 133 is located in the rotating circle 132 and can rotate in the rotating circle 132. A second limiting block 134 is provided on the inner wall of the rotating circle 132, and a third limiting block 135 is provided on the outer wall of the rotating circle 132, and the third limiting block 135 is limited by the inner wall of the fixing shell 124. The rotating circle 132 facilitates the fixing member 111 to rotate relative to the fixing seat 109 and the fixing block 110, thereby enabling the lamp to rotate relative to the fixing seat 109 and the fixing block 110, so as to facilitate the adjustment of the lighting angle of the lamp.

[0064] When the lamp is rotated, the lamp drives the fixing member 111 to rotate together, and the first limit block 133 of the fixing member 111 rotates in the rotating circle 132 along the inner wall of the rotating circle 132. The first limit block 133 can rotate from one side of the second limit block 134 to the other side of the second limit block 134, which is called the first rotation stroke. The first rotation stroke is equal to 360° minus the angle occupied by the first limit block 133 and the second limit block 134, which is close to 360°.

[0065] Then, the first limit block 133 continues to push the second limit block 134 from the other side of the second limit block 134 to rotate together, thereby driving the rotating circle 132 to rotate together, and the third limit block 135 located on the outer wall of the rotating circle 132 also rotates together, and can rotate from the inner wall of one side of the fixed shell 124 to the inner wall of the other side of the fixed shell 124. Since the second limit block 134, the third limit block 135 and the rotating circle 132 are integrated, the rotation stroke of the second limit block 134 is equal to the rotation stroke of the third limit block 135, and is also equal to the rotation stroke of the rotating circle 132, which is called the second rotation stroke. The second rotation stroke is equal to the angle of the third limit block 135 rotating from the inner wall of one side of the fixed shell 124 to the inner wall of the other side of the fixed shell 124.

[0066] Therefore, the rotation angle of the first limit block 133 is equal to the sum of the first rotation stroke and the second rotation stroke. Since the width and angle between the inner walls on both sides of the fixed shell 124 are greater than the width and angle of the first limit block 133 and the second limit block 134, the sum of the rotation angles of the first limit block 133 can completely exceed 360°. Therefore, the fixing member 111 can be rotated arbitrarily within the range of 360°, and then the lamp can be rotated arbitrarily within the range of 360°, which is convenient for adjusting the lighting angle of the lamp.

[0067] In this embodiment, at least one end of the fixed seat 109 is provided with an arc wall 136, and the arc wall 136 and the inner wall of the fixed shell 124 jointly limit the rotation stroke of the rotating circle 132, and the third limit block 135 can rotate along the arc wall 136. Since the fixing member 111 and the rotating circle 132 are light in weight, they may shift or make non-directional movements during the rotation process, resulting in rotation jamming or the entire structure being misplaced and unable to be used normally. Since the third limit block 135 can only rotate between the inner walls of the fixed shell 124 at one end, an arc wall 136 is provided at the corresponding end of the fixed seat, and the arc wall 136 and the inner wall of the fixed shell 124 jointly limit the rotation stroke of the rotating circle 132, which plays a role of limiting and directing, ensuring that the rotating circle 132 can stably rotate within the rotation stroke, and can be used for a long time and reliably. In addition, the arc wall 136 is a rib-shaped structure, which can also increase the structural strength of the fixed seat 109.

[0068] In this embodiment, arc-shaped walls 136 are provided at both ends of the fixing seat 109 , so that the third limiting block 135 can stably rotate no matter which end it is placed at, and the structural strength of the fixing seat 109 is further increased.
