Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and particularly relates to a precise positioning and marking mechanism for a spot lamp. Background Technique

[0002] A spot lamp is a widely used lighting fixture, which can provide high-brightness lighting at a long distance. Currently, most spot lamps are fixed and cannot adjust the reflection angle of the reflector cup, resulting in low applicability and inability to meet the needs of various angles.

[0003] For this reason, a spot lamp angle adjustment mechanism with the publication number of "CN209130793U" includes an adjustment ring. A fixed shell capable of being connected to the reflector cup is sleeved outside the adjustment ring. The adjustment ring is hinged to the fixed shell, and an adjustment device capable of changing the rotation angle of the fixed shell is arranged between the adjustment ring and the fixed shell. By providing the adjustment device, the angle between the adjustment ring and the fixed shell can be adjusted, so that the reflection angle between the reflector cup installed in the fixed shell and the light source installed in the adjustment ring is changed, meeting the multi-angle requirements of the spot lamp, improving the applicability, and having a simple structure and convenient use.

[0004] However, for the above-mentioned spot lamp angle adjustment mechanism, although the positioning bead is pressed against the arc-shaped limiting device by a spring to fix the angle between the adjustment ring and the fixed shell, when the fixed shell rotates, the positioning bead is pressed towards the spring direction, causing the positioning bead to move a preset distance to quickly change the angle between the fixed shell and the adjustment ring. There are still the following obvious defects during use: In the positioning where the positioning bead is tightened by a spring for angle adjustment, since the spring is prone to bending during angle adjustment and centering, the phenomenon that the positioning bead breaks away from the spring and drops occurs, which will cause the problem that the fixed adjustment ring cannot be angle-positioned and shakes after adjustment. Content of the Utility Model

[0005] The purpose of the utility model is to provide a precise positioning and marking mechanism for a spot lamp to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A precise positioning and marking mechanism for a spot lamp, including:

[0007] A spot lamp shell, one end of the spot lamp shell is clamped with an adjustment and fixing seat for adjusting the angle of the light irradiated by the spot lamp and having a semi-circular arc surface at one end. The adjustment and fixing seat is movably installed with an angle adjustment mechanism for angle adjustment movement and positioning through a provided connecting seat. The other end of the angle adjustment mechanism is externally sleeved and clamped with a reflector cup for diffusely reflecting the emitted light source. The reflector cup and the angle adjustment mechanism are clamped and sleeved with a spot lamp installation cover for installing the spot lamp.

[0008] Preferably, the adjusting fixing seat is provided with a positioning clamping plate at one end of a semi-circular arc shape, and a connecting piece seat which is movably connected to the angle adjusting mechanism and has a semi-circular shape at one end extends outward from the central positions of the two perpendicular ends of the port of the adjusting fixing seat. A cylindrical limiting block is provided at a position corresponding to one side of the connecting piece, so as to play a role of angle limiting by using the cylindrical limiting block during the adjustment of the adjusting housing.

[0009] Preferably, the angle adjusting mechanism includes an adjusting housing. A relief beveled opening part is provided at one end of the adjusting housing to prevent interference with the semi-circular arc surface on the adjusting fixing seat during rotation. On the inner side wall of the adjusting housing, outwardly protruding strip-shaped angle fixing blocks arranged in order from long to short are horizontally provided at equal intervals. Arc-shaped limiting chutes are provided on both perpendicular surfaces at one end of the adjusting housing. Adjusting angle marks are provided on the corresponding surfaces of the adjusting housing, so that the adjusting housing can be accurately adjusted and positioned according to the adjusting angle marks.

[0010] Preferably, the adjusting fixing seat is installed inside the relief beveled opening part at one end of the adjusting housing, and the connecting piece seat is movably connected to the adjusting housing by being sleeved with screws. The cylindrical limiting block is arranged inside the limiting chute, which is beneficial for the adjusting housing to perform angle adjustment and movement on the adjusting fixing seat, so as to realize the angle adjustment of the reflector cup.

[0011] Preferably, vertical strip-shaped grooves are formed on both sides of the positioning clamping plate, so that after the positioning clamping plate is movably connected to the adjusting fixing seat and the adjusting housing, it is positioned and abuts against one side of the outwardly protruding strip-shaped angle fixing block for angle positioning, so as to realize the tightening and positioning of the adjusting housing after angle adjustment and maintain the firmness of the angle.

[0012] Preferably, strip-shaped plates for ceiling installation and fixing of the spotlight are installed on the front and rear sides at one end of the spotlight installation cover, and the other end of the strip-shaped plate extends in two directions and is provided with a bending angle, so as to make the spotlight more firm during angle adjustment after the high spotlight is installed.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the spotlight precise positioning identification mechanism is connected by the combination of the positioning card plate, the connecting plate seat, and the adjusting shell, the giving way bevel portion, the outer convex strip angle fixing block, the limiting slide groove, the adjusting angle identification, and the cylindrical limiting block on the adjusting seat fixing seat. When the reflector cup is adjusted in angle, the adjusting shell uses the giving way bevel to move the angle at one end of the semi-circular adjusting fixing seat. At the same time, through the adaptation of the cylindrical limiting block and the circular arc limiting slide groove, The angle is adjusted by limiting the position, and the positioning card is used to slide into the cavity between the convex strip angle fixing blocks and press against the side inclined surface during the angle adjustment of the reflective cup. At the same time, the angle of the arc surface spacing between the convex strip angle fixing blocks arranged in sequence from long to short at equal intervals is 5 degrees, so the reflective cup is adjusted at an angle of 5 degrees, and then the reflective cup can be adjusted one by one at a small angle at a time to improve the accuracy of the adjustment angle, thereby ensuring the stability of the reflective cup after the angle adjustment, and solving the problems and defects in the prior art.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1-3 The utility model provides a technical solution: a spotlight accurate positioning identification mechanism, comprising:

[0021] A spotlight housing 1, one end of the spotlight housing 1 is snap-connected with an adjustment and fixing seat 3 that adjusts the angle of the light irradiated by the spotlight and has a semi-circular arc surface at one end. A square snap is provided at the end of the adjustment and fixing seat 3 connected to the spotlight housing 1, and a snap projection is provided at the position where the square snap is snap-connected to the inner wall of one end of the spotlight housing 1, so that the spotlight housing 1 and the adjustment and fixing seat 3 are snap-connected. The adjustment and fixing seat 3 is movably installed with an angle adjustment mechanism 4 for angle adjustment movement and positioning through a connecting seat provided thereon, which can perform directional angle adjustment of the irradiation angle of the light source generated by the spotlight light source board. The other end of the angle adjustment mechanism 4 is externally sleeved and snap-connected with a reflector cup 5 that diffuses and reflects the light source emitted by the spotlight light-emitting body, so that the generated light source can be irradiated at different angles under the angle adjustment of the reflector cup 5. The reflector cup 5 and the angle adjustment mechanism 4 are snap-fitted with a spotlight mounting cover 6 for mounting and fixing the spotlight.

[0022] One end of the adjustment and fixing seat 3 with a semi-circular arc shape is provided with a positioning card board 7, so that the adjustment housing 9 is tightly pressed in the clearance cavity between the outwardly convex strip-shaped angle fixing blocks 11 during angle adjustment for tight positioning after angle adjustment. And at the central positions extending outward perpendicular to both ends of the port of the adjustment and fixing seat 3, there are connecting piece seats 8 that are movably connected to the angle adjustment mechanism 4 and have a semi-circular shape at one end, so that the adjustment housing 9 is sleeved outside one end of the adjustment and fixing seat 3 with a semi-circular outer arc structure and is movably locked through screws. A cylindrical limit block 14 is provided at a corresponding position on one side of the connecting piece seat 8. During angle adjustment, the adjustment housing 9 makes the angle adjustment more accurate by using the cylindrical limit block 14 to limit the angle in the limit sliding groove 12, and there will be no phenomenon of angle error.

[0023] The angle adjustment mechanism 4 includes an adjustment housing 9. One end of the adjustment housing 9 is provided with a relief beveled opening 10 that prevents interference with the semi-circular arc surface on the adjustment and fixing seat 3 during rotation, which is beneficial to the angle adjustment of the adjustment housing 9. On the inner side wall of the adjustment housing 9, outwardly convex strip-shaped angle fixing blocks 11 arranged in order from long to short are equidistantly horizontally provided. The spacing arc angles between the outwardly convex strip-shaped angle fixing blocks 11 are all 5 degrees. At the same time, during angle adjustment, one-by-one adjustment of 5-degree angles is performed to achieve the accuracy of adjustment. After the adjustment housing 9 is adjusted to an appropriate angle, the positioning card board 7 can be used to limit the sides with inclined surfaces on both sides. Both vertical surfaces at one end of the adjustment housing 9 are provided with arc-shaped limit sliding grooves 12, and adjustment angle marks 13 are provided on the surfaces of the adjustment housing 9 corresponding to the limit sliding grooves 12, so that the adjustment housing 9 can accurately position the reflector cup 5.

[0024] The adjustment fixing base 3 is installed inside the inner side of the end of the adjustment housing 9 with a relief beveled portion 10, and the connecting piece base 8 is sleeved and movably connected to the adjustment housing 9 by screws. The cylindrical limiting block 14 is arranged inside the limiting sliding groove 12. Vertical strip-shaped grooves are formed on both sides of the positioning card plate 7, so that after the positioning card plate 7 is movably connected to the adjustment fixing base 3 and the adjustment housing 9, it is positioned and abuts against one side of the convex strip-shaped angle fixing block 11 for angle positioning. On the front and rear sides of one end of the spotlight installation cover 6, strip-shaped plates 15 for ceiling installation and fixing of the spotlight are installed, and the other end of the strip-shaped plate 15 extends in two directions and is provided with bending angles.

[0025] Specifically, during use, when the irradiation angle of the spotlight needs to be adjusted, the end of the adjustment housing 9 with the relief beveled portion 10 is adjusted and moved in angle by using the movable connection with the connecting piece base 8, and the reflector cup 5 installed inside the adjustment housing 9 moves synchronously in angle. In order to enable the adjustment housing 9 to accurately adjust the angle, the limiting sliding groove 12 moves in an arc angle outside the cylindrical limiting block 14, and the position of the cylindrical limiting block 14 corresponding to the adjustment angle mark 13 is the specific angle of adjustment of the adjustment housing 9. During the angle adjustment process of the adjustment housing 9, the outer side of the positioning card plate 7 on one side inside the adjustment fixing base 3 moves on the surface of the equidistantly arranged convex strip-shaped angle fixing blocks 11, and the arc spacing angle between the convex strip-shaped angle fixing blocks 11 is a 5-degree adjustment angle gap. Then, the adjustment housing 9 can be adjusted by an angle of 5 degrees at a time. After the adjustment housing 9 is adjusted, it is tightened against the inclined surface on one side of the convex strip-shaped angle fixing block 11, so that the reflector cup 5 can be adjusted at multiple irradiation angles by using the adjustment housing 9, and at the same time, the stability of the angle position of the adjustment housing 9 after the angle adjustment is ensured, thereby making the angle adjustment of the spotlight more accurate.
