[0030] It is understandable that, referring to Figures 1 to 4The utility model of the light-cutting lamp comprises a barrel 100, a focusing mechanism 200 and a light-cutting mechanism 300. The barrel 100 is provided with a receiving cavity 110, and a lamp bead 120 is fixedly connected in the receiving cavity 110; the focusing mechanism 200 comprises a first slide 210 and a second slide 220, the first slide 210 and the second slide 220 are both slidably connected to the barrel 100, and the first slide 210 and the second slide 220 are both fixedly connected with a plurality of lenses 230. Along the axial direction of the barrel 100, the inner wall of the receiving cavity 110 is provided with a plurality of guide grooves 111, and the outer walls of the first slide 210 and the second slide 220 are convex. A plurality of guide blocks 240 are provided, and the guide blocks 240 are slidably connected to the guide grooves 111, and the guide grooves 111 correspond to the guide blocks 240 one by one; the light cutting mechanism 300 includes a support frame 310 and a plurality of light cutting pieces 320, and the support frame 310 is arranged between the lamp bead 120 and the first slide frame 210, and a light-transmitting hole 311 is opened in the middle of the support frame 310, and the lamp bead 120 is connected to the light-transmitting hole 311, and an adjustment groove 312 connected to the light-transmitting hole 311 is opened on the side wall of the support frame 310, and a plurality of light cutting pieces 320 are inserted in the adjustment groove 312 so that the light cutting pieces 320 can block the light-transmitting hole 311.

[0031] The lamp bead 120 is fixed in the accommodating cavity 110, and the first slide 210 and the second slide 220 are both slidably connected to the barrel 100 so that the first slide 210 and the second slide 220 can slide in the accommodating cavity 110. The first slide 210 and the second slide 220 are both fixedly connected with a plurality of lenses 230, so that the lamp bead 120, the first slide 210 and the second slide 220 are arranged in sequence along the axial direction of the barrel 100. By moving the first slide 210 and the second slide 220 to adjust the position of the lens 230, the size of the light spot emitted by the lamp bead 120 can be adjusted. The support frame 310 is arranged between the lamp bead 120 and the first slide 210, a light-transmitting hole 311 is provided in the middle of the support frame 310, an adjustment groove 312 is provided on the side wall of the support frame 310, and a plurality of light-cutting pieces 320 are arranged in the adjustment groove 312. The lamp bead 120 is connected to the light-transmitting hole 311 so that the light emitted by the lamp bead 120 can pass through the light-transmitting hole 311. Through the cooperation of the plurality of light-cutting pieces 320, the shape of the light-transmitting hole 311 can be adjusted, and the shape of the light spot can be changed to meet different lighting requirements. The inner wall of the accommodating cavity 110 is provided with a guide groove 111, and the outer walls of the first slide 210 and the second slide 220 are both protrudingly provided with a guide block 240. By setting the guide block 240 to slide in the guide groove 111, the position of the first slide 210 and the second slide 220 in the accommodating cavity 110 can be positioned, so as to avoid the position deviation of the lens 230, so that the shape of the light spot can be kept stable and the illumination effect can be improved.

[0032] It should be noted that the first slide 210 and the second slide 220 are flipped radially in the accommodating chamber 110, which may easily cause the position of the lens 230 to shift, affecting the shape of the light spot, and the first slide 210 and the second slide 220 are easily stuck on the inner wall of the accommodating chamber 110, affecting the adjustment of the light-cutting lamp. By setting the number of guide grooves 111 and guide blocks 240 to be multiple, and the multiple guide grooves 111 are arranged at intervals on the inner wall of the accommodating chamber 110, the sliding stability of the first slide 210 and the second slide 220 in the accommodating chamber 110 can be improved, so that the shape of the light spot can be kept stable, and the pressure of the guide block 240 on the guide groove 111 can be reduced, so as to reduce wear and extend the service life.

[0033] It is understandable that, referring to Figure 3 and Figure 4 The side wall of the guide groove 111 is provided with a groove 112, and the side wall of the guide block 240 is provided with a protruding block 241, and the protruding block 241 can slide in the groove 112. The side wall of the guide groove 111 is provided with a groove 112, and the side wall of the guide block 240 is provided with a protruding block 241. By setting the protruding block 241 to slide in the groove 112, the contact area between the barrel 100 and the first slide 210 or the second slide 220 can be increased, so that the first slide 210 and the second slide 220 can move smoothly in the barrel 100, improve the movement smoothness of the first slide 210 and the second slide 220, reduce the position shaking of the lens 230, and improve the stability of the light spot.

[0034] The shapes of the groove 112 and the protrusion 241 match, so that the protrusion 241 can fit on the wall surface of the groove 112, so that the protrusion 241 can be stabilized in the groove 112, and the position shaking of the protrusion 241 in the groove 112 is reduced, so that the first slide 210 and the second slide 220 can slide smoothly in the accommodating cavity 110. The cross-sectional shape of the groove 112 and the protrusion 241 can be set to a semicircular shape, which can increase the contact area between the groove 112 and the protrusion 241, reduce the amplitude of the shaking of the protrusion 241 in the groove 112, and can slow down the wear of the groove 112 and the protrusion 241, thereby improving the reliability of the focusing mechanism 200.

[0035] Specifically, refer to Figure 3 and Figure 4, the number of the grooves 112 and the protrusions 241 are both set to two, the two grooves 112 are respectively arranged on both sides of the guide groove 111, the two protrusions 241 are respectively arranged on both sides of the guide block 240, and the grooves 112 and the protrusions 241 are in one-to-one correspondence. The number of the grooves 112 and the protrusions 241 are both set to two, by setting two grooves 112 arranged on both sides of the guide groove 111, and two protrusions 241 arranged on both sides of the guide block 240, so that the grooves 112 and the protrusions 241 are in one-to-one correspondence, the contact area between the barrel 100 and the first slide 210 or the second slide 220 can be increased, and the protrusions 241 can be balanced in force, so as to reduce wear, extend the service life, and improve the reliability of the focusing mechanism 200.

[0036] It is understandable that, referring to Figure 1 and Figure 2 A slide groove 130 is formed on the side wall of the cylinder 100 , and a screw rod 211 is threadedly connected to the first slide 210 . The screw rod 211 is inserted into the slide groove 130 , and the screw rod 211 can slide along the length direction of the slide groove 130 . The slide groove 130 is set on the side wall of the barrel 100, and the slide groove 130 is arranged along the axial direction of the barrel 100. The screw 211 is threadedly connected to the first slide 210, and the screw 211 is penetrated in the slide groove 130. The screw 211 is driven to slide in the slide groove 130 so that the first slide 210 can move along the axial direction of the barrel 100, which is convenient for adjusting the position of the first slide 210 and the position of the lens 230. Then, the screw 211 is driven to rotate so that the screw 211 can press the first slide 210 against the inner wall of the accommodating cavity 110 to avoid the position of the first slide 210 from shaking, so that the position of the lens 230 can remain stable, thereby stabilizing the shape of the light spot and improving the reliability of the focusing mechanism 200.

[0037] Among them, the number of slide grooves 130 and screw rods 211 can be set to multiple, and the slide grooves 130 and the screw rods 211 can be made to correspond one to one. By cooperating with multiple slide grooves 130 and multiple screw rods 211, the position stability of the first slide 210 can be improved, so that the first slide 210 can be stabilized in the accommodating cavity 110, and the position of the first slide 210 can be prevented from shaking.

[0038] It should be noted that in order to improve the position stability of the second slide 220, a screw 211 can also be provided to be threadedly connected to the second slide 220, and a slide groove 130 for accommodating the screw 211 can be opened on the side wall of the cylinder 100 corresponding to the second slide 220, so that the position of the second slide 220 can be easily adjusted, and the second slide 220 can be pressed against the inner wall of the accommodating chamber 110 through the screw 211 to stabilize the position of the second slide 220 and prevent the position of the second slide 220 from shaking.

[0039] It is understandable that, referring to Figure 1 and Figure 5 The number of the adjustment slots 312 is set to be multiple, and the multiple adjustment slots 312 are arranged at intervals along the axial direction of the light transmission hole 311. By setting the multiple adjustment slots 312 to be arranged at intervals along the axial direction of the light transmission hole 311, the multiple light cutting pieces 320 can be distributed in the adjustment slots 312, thereby increasing the movement range of the light cutting pieces 320, improving the flexibility of adjusting the shape of the light spot, and enhancing the user experience of the light cutting lamp.

[0040] It should be noted that each adjustment slot 312 may be provided with two light cutting pieces 320 , and the two light cutting pieces 320 are symmetrically arranged in the circumferential direction of the adjustment slot 312 , thereby reducing the possibility of the light cutting pieces 320 blocking each other and improving the adjustment flexibility of the light spot.

[0041] It is understandable that, referring to Figure 1 and Figure 2 The barrel 100 is connected with a connecting rod 140, and the connecting rod 140 is rotatably connected to the bottom end of the barrel 100. The connecting rod 140 is rotatably connected to the bottom end of the barrel 100, so that the barrel 100 can rotate around the connecting rod 140, so that the irradiation position of the light spot can be conveniently adjusted, and the convenience of using the cutting light lamp is improved.

[0042] The connecting rod 140 may be fixedly connected to a wall, a ceiling, or the like, so that the cylinder 100 can smoothly rotate around the connecting rod 140 .

[0043] Specifically, refer to Figure 1 and Figure 2 The barrel 100 is provided with an avoidance groove 141, which is arranged adjacent to the connecting rod 140, and the connecting rod 140 is inserted into the avoidance groove 141. The avoidance groove 141 is arranged on the side wall of the barrel 100, and the connecting rod 140 is inserted into the avoidance groove 141, so that when the barrel 100 rotates, the connecting rod 140 can extend into the avoidance groove 141, thereby increasing the rotation angle of the barrel 100, facilitating the arrangement of the position of the light spot, and improving the convenience of using the cut-light lamp.

[0044] It is understandable that, referring to Figure 2 The barrel 100 further includes a support plate 150, which is fixedly connected to the inner wall of the accommodating chamber 110, and the lamp bead 120 is arranged on the support plate 150. The lamp bead 120 is fixedly connected to the support plate 150, and the support plate 150 is fixedly connected to the inner wall of the accommodating chamber 110, so that the heat generated by the lamp bead 120 can be guided to the barrel 100 through the support plate 150, accelerate the dissipation of heat, reduce the temperature of the lamp bead 120, extend the service life of the lamp bead 120, and improve the reliability of the cut-off lamp.

[0045] It is understandable that, referring to Figure 1 and Figure 2The cylinder 100 is fixedly connected to the limiting cover 160, and the second slide 220 can abut against the limiting cover 160 to limit the position of the second slide 220. The limiting cover 160 is fixedly connected to the cylinder 100, and the second slide 220 can abut against the limiting cover 160. By setting the limiting rod, the position of the second slide 220 can be limited to prevent the second slide 220 from sliding out of the accommodating cavity 110, thereby improving the reliability of the light-cutting lamp.

[0046] It is understandable that, referring to Figure 1 and Figure 5 The end of the light cutting piece 320 is connected with a handle 321. By providing the handle 321 at the end of the light cutting piece 320, it is convenient for the user to grasp it, so that the position of the light cutting piece 320 in the adjustment slot 312 can be easily adjusted, and then the shape of the light spot can be easily adjusted, thereby improving the convenience of using the light cutting lamp.

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
