[0002] When installing stadium lighting fixtures, it is usually necessary to use appropriate installation structures and auxiliary tools, such as laser pointers, to adjust the illumination angle of the fixtures according to the needs of use and the installation location. This is generally divided into horizontal and vertical angle adjustment. However, due to various factors that may affect the on-site adjustment of the fixtures, such as height, the professionalism of the workers, and the weight of the fixtures, the angle of the fixtures after on-site installation may differ from the designed angle, making it difficult to accurately adjust the projection angle of the fixtures. Utility Model Content

[0003] The purpose of this invention is to provide a lamp projection angle positioner to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A lamp projection angle positioner includes a positioning module. The positioning module is equipped with a limit module. The positioning module includes a mounting plate, an adjusting seat, and a mounting base. The adjusting seat has two arc-shaped grooves and two arc-shaped grooves. The mounting plate is screwed with two positioning screws passing through adjacent arc-shaped grooves. The mounting base is screwed with two positioning screws passing through the interior of the arc-shaped grooves. Both the mounting plate and the adjusting seat are provided with scales. The adjusting seat is fixedly connected with two indicator blocks, and the mounting base is fixedly connected with indicator blocks. The mounting plate has two scales, and the adjusting seat has one scale. The two indicator blocks correspond to the two scales on the mounting plate, and the indicator blocks correspond to the scale on the adjusting seat. The adjusting seat is rotatably connected to the mounting plate.

[0006] Furthermore, a handle is fixedly connected to the bottom surface of the mounting base.

[0007] Furthermore, the adjusting seat and the mounting seat are provided with connecting screws inside, and the connecting screws are screwed with nuts, and the connecting screws pass through the interior of the adjusting seat and the mounting seat.

[0008] Furthermore, both the positioning screw one and the positioning screw two are provided with washers. The washer on the positioning screw one contacts the inner side of the arc groove one, and the washer on the positioning screw two contacts the side of the adjusting seat.

[0009] Furthermore, the adjustment seat has two connecting slots;

[0010] The limiting module includes a toothed ring one and a toothed ring two;

[0011] The toothed ring is fixedly connected to two limiting blocks, and each limiting block is provided with an adjusting screw that is screwed into the mounting plate.

[0012] The second retaining ring engages with the first retaining ring, and the second retaining ring is fixedly connected to two second limiting blocks, which are screwed together with limiting screws extending into the adjacent connecting groove.

[0013] Furthermore, the adjusting screw has an annular groove, the limiting block 1 contacts the inner side of the annular groove, and the thickness of the annular groove is greater than the thickness of the limiting block 1.

[0014] Preferably, the mounting base is screwed onto a contact screw;

[0015] The limiting module also includes a positioning frame and an abutment frame;

[0016] The positioning frame is fixedly connected to the second retaining ring;

[0017] The abutment frame is fixedly connected to two sliding rods that are slidably connected to the positioning frame. The abutment frame is rotatably connected to an adjusting screw that is screwed into the positioning frame. The side of the abutment frame abuts against the side of the abutment screw.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Both the mounting plate and the adjusting seat are equipped with graduations. After the mounting plate is installed on the horizontal or vertical surface of the corresponding support frame, the adjusting seat can be rotated relative to the mounting plate as needed, and the mounting seat can be rotated relative to the adjusting seat. The installation angle of the mounting seat can be adjusted according to the design requirements. During the adjustment process, the rotation angle of the adjusting seat relative to the mounting plate can be known through the indications on the mounting plate by indicator block one and indicator block two on the adjusting seat. The rotation angle of the mounting seat relative to the adjusting seat is conducive to accurately adjusting the horizontal and vertical angles of the mounting seat relative to the mounting plate, which helps to reduce the difference between the lamp angle and the design angle, and facilitates more accurate installation of the lamp.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3In this embodiment of the utility model, the lamp projection angle positioner includes a positioning module 100, which is equipped with a limit module 200. The positioning module 100 includes a mounting plate 110, an adjusting seat 120, and a mounting seat 130. The adjusting seat 120 has an arc-shaped groove 122 and two arc-shaped grooves 121. The adjusting seat 120 also has two connecting grooves 124. The mounting plate 110 is screwed with two positioning screws 111 that pass through adjacent arc-shaped grooves 121. The mounting seat 130 is screwed with two positioning screws 132 that pass through the interior of the arc-shaped groove 122. Both screw 111 and positioning screw 132 are provided with washers. The washer on positioning screw 111 contacts the inner side of arc groove 121, and the washer on positioning screw 132 contacts the side of adjusting seat 120. The adjusting seat 120 and mounting seat 130 are provided with connecting screws 150. The connecting screws 150 are screwed with nuts and pass through the interior of adjusting seat 120 and mounting seat 130. The mounting seat 130 can rotate relative to the adjusting seat 120 with the connecting screws 150 as the center. The adjusting seat 120 and mounting seat 130 are connected by the connecting screws 150.

[0029] Both the mounting plate 110 and the adjusting seat 120 are provided with scales, and the scale accuracy on the mounting plate 110 and the adjusting seat 120 is 1°. The adjusting seat 120 is fixedly connected to two indicator blocks 123, and the mounting seat 130 is fixedly connected to an indicator block 131. The mounting plate 110 is provided with two scales, and the adjusting seat 120 is provided with one scale. The two indicator blocks 123 correspond to the two scales on the mounting plate 110, and the indicator block 131 corresponds to the scale on the adjusting seat 120. The adjusting seat 120 is rotatably connected to the mounting plate 110.

[0030] Specifically, the mounting plate 110 can be installed on the horizontal or vertical surface of the corresponding support frame. Then, as needed, the adjusting seat 120 can be rotated relative to the mounting plate 110, and the mounting seat 130 can be rotated relative to the adjusting seat 120. This allows the arc-shaped groove 121 to rotate relative to the positioning screw 111, and the arc-shaped groove 122 to rotate relative to the positioning screw 132. The installation angle of the mounting seat 130 can then be adjusted according to design requirements. During adjustment, the rotation angles of the adjusting seat 120 relative to the mounting plate 110 and the mounting seat 130 relative to the adjusting seat 120 can be determined by the markings on the mounting plate 110 and the adjusting seat 120, respectively, indicated by the markings on the adjusting seat 120 and the adjusting seat 130. Referencing these markings facilitates precise adjustment of the mounting seat 130. The angle between the horizontal and vertical directions of the mounting plate 110 helps to reduce the difference between the lamp angle and the design angle, making it easier to install the lamp more accurately. After the adjustment is completed, the positioning screw 111 and the positioning screw 132 can be tightened so that the end of the positioning screw 111 abuts against the corresponding washer on the adjusting seat 120, and the end of the positioning screw 132 abuts against the corresponding washer in the arc groove 121. This fixes the adjusting seat 120 and the mounting plate 110 together, and fixes the adjusting seat 120 and the mounting seat 130 together. Then the nut can be tightened so that the nut and the large end of the connecting screw 150 abut against the mounting seat 130 and the adjusting seat 120 respectively, fixing the adjusting seat 120 and the mounting seat 130 together. Finally, the lamp is installed on the mounting seat 130.

[0031] By setting scales on both the mounting plate 110 and the adjustment base 120, it is beneficial to ensure the aiming angle of the lamps, guarantee the lighting effect after installation, and ensure that the lamps can return to the original aiming angle after maintenance, thus ensuring the lighting effect. The horizontal and vertical projection angles of the lamps can be set according to different projects and adjusted before leaving the factory. During on-site installation, the lamp angles can be finely adjusted according to the site conditions. The installation is relatively simple and the adjustment is relatively easy, which helps to ensure that the lighting design results are as similar as possible to the actual installation effect.

[0032] Example 1

[0033] like Figure 2 As shown, in this embodiment, a handle 140 is fixedly connected to the bottom surface of the mounting base 130.

[0034] In practice, during installation, the angle of the mounting base 130 can be adjusted by holding the handle 140, making it easier to lift the positioning module 100 through the handle 140 and to carry the positioning module 100.

[0035] like Figure 1-4 As shown, in this embodiment, the limiting module 200 includes a first retaining ring 210 and a second retaining ring 220;

[0036] The retaining ring 210 is fixedly connected to two limiting blocks 211. Each limiting block 211 has an adjusting screw 212 that screws into the mounting plate 110. The adjusting screw 212 has an annular groove 213. The limiting block 211 contacts the inner surface of the annular groove 213. The thickness of the annular groove 213 is greater than the thickness of the limiting block 211. The retaining ring 210 and the limiting blocks 211 can be connected to the mounting plate 110 via the adjusting screw 212. The retaining ring 220 engages with... When the first toothed ring 210 rotates one tooth relative to the second toothed ring 220, the first toothed ring 210 rotates 1° relative to the second toothed ring 220. The second toothed ring 220 is fixedly connected to two limit blocks 221. The limit blocks 221 are screwed together with limit screws 222 extending into the adjacent connecting grooves 124. By inserting the limit screws 222 into the corresponding connecting grooves 124, the second toothed ring 220 and the limit blocks 221 can be connected to the adjusting seat 120.

[0037] In practice, before adjusting the angle of the adjusting seat 120, the adjusting screw 212 can be rotated one full turn in the forward direction, moving it towards the mounting plate 110. This causes one inner wall of the annular groove 213 to no longer abut against the limiting block 211. At this point, the retaining ring 210 can move away from the retaining ring 220, thus separating it from the retaining ring 220. The adjusting seat 120 can then rotate relative to the mounting plate 110. The adjusting seat 120 can drive the retaining ring 220 to rotate via the limiting screw 222. After adjustment, the retaining ring 210 can be moved towards the retaining ring 220, re-engaging it with the retaining ring 220. Then, the two adjusting screws 212 can be rotated one full turn in opposite directions. The inner wall of the adjusting screw 212 abuts against the limiting block 211, thereby limiting the position of the limiting block 211 and the position of the retaining ring 210. This keeps the retaining ring 210 and retaining ring 220 engaged. In this way, the mounting plate 110 and the adjusting seat 120 can be initially positioned by the retaining ring 210 and retaining ring 220. When tightening the positioning screw 111 with appropriate tools to completely fix the adjusting seat 120 on the mounting plate 110, it is not necessary to manually maintain the angle of the adjusting seat 120. This makes it easier for workers to operate at height and avoids the adjusting seat 120 from rotating relative to the mounting plate 110 during the tightening process, which is conducive to more precise adjustment of the angle of the adjusting seat 120.

[0038] Example 2

[0039] Based on Example 1, such as Figure 5 As shown, in this embodiment, the mounting base 130 is screwed onto the abutment screw 300;

[0040] The limiting module 200 also includes a positioning frame 230 and an abutment frame 240;

[0041] The positioning frame 230 is fixedly connected to the toothed ring 220. The abutment frame 240 is fixedly connected to two sliding rods 241 that are slidably connected to the positioning frame 230. The abutment frame 240 and the positioning frame 230 can be connected by the sliding rods 241 to limit the movement direction of the abutment frame 240 relative to the positioning frame 230. The abutment frame 240 is rotatably connected to an adjusting screw 242 that is screwed into the positioning frame 230. The positioning frame 230 and the abutment frame 240 can be fixed to each other by adjusting the screw 242. The side of the abutment frame 240 abuts against the side of the abutment screw 300.

[0042] In specific implementation, when the mounting plate 110 is installed on a horizontal surface, the abutting screw 300 can be abutted against the outer surface of the abutting frame 240. At this time, under the action of the weight of the mounting base 130 itself, the abutting screw 300 will abut against the abutting frame 240. When the mounting plate 110 is installed on a vertical surface, the adjusting screw 242 can be rotated first to move the abutting frame 240 away from the positioning frame 230. Then, the abutting screw 300 is screwed into the mounting base 130 through the inside of the abutting frame 240. At this time, under the action of the weight of the mounting base 130, the abutting screw 300 can abut against the side of the abutting frame 240.

[0043] After the abutting screw 300 abuts against the outer or inner side of the abutting frame 240, the adjusting screw 242 can be rotated to move the abutting frame 240 towards the positioning frame 230. At this time, under the action of gravity, the mounting base 130 will rotate, so that the abutting screw 300 remains against the outer side of the abutting frame 240, or the abutting frame 240 can push the abutting screw 300 to move through its inner side, thereby adjusting the position of the mounting base 130. In this way, the angle of the mounting base 130 can be adjusted by rotating the adjusting screw 242, which is convenient for fine-tuning the angle of the mounting base 130. The angle of the mounting base 130 can also be positioned by the abutting frame 240 and the abutting screw 300, which is helpful for determining the angle of the mounting base 130. When tightening the positioning screw 132, try to avoid the mounting base 130 from rotating relative to the adjusting base 120.

[0044] After installation, the abutment screw 300 can be unscrewed, and then the limit screw 222 can be rotated to separate the limit screw 222 from the connecting groove 124. Then, the adjusting screw 212 can be rotated in the opposite direction to separate the adjusting screw 212 from the mounting plate 110. At this time, the retaining ring 1 210 and retaining ring 220 can be passed through the adjusting seat 120 and the mounting seat 130, and then the limit module 200 can be removed from the positioning module 100. Then, the lamp can be installed on the mounting seat 130. In this way, the limit module 200 can be reused, and only a small number of limit modules 200 need to be configured for several positioning modules 100.
