Description

Technical Field

[0001] This utility model belongs to the technical field of lighting devices, specifically relating to an installation mechanism and a lamp. Background Technology

[0002] In lighting fixtures used for floodlighting or wall washing, different lighting angles can be achieved by adjusting the rotation angle of the lamp body. The installation method for floodlights or wall washers is generally as follows: the lamp body is first installed into a bracket using a sliding bracket structure or an external clip-on bracket structure, and then the bracket is installed into another bracket for fixed connection with the external foundation.

[0003] Whether using a sliding or snap-on bracket structure, adjusting the lighting angle of the lamp requires loosening the screws in the bracket. The operator needs to use a wrench to hold the nut on one side of the bracket with one hand, while using a screwdriver or other adjusting tool on the other side to loosen the screw. Then, the lamp body can be rotated to adjust the beam angle. After adjustment, the above steps are repeated to tighten the screws. This process is complex and makes it difficult to rotate the lamp body and adjust the beam angle.

[0004] In addition, brackets often require painting, which can cause powder to accumulate in the mounting holes. When screws are tightened onto the brackets, the powder can easily cause the screws to strip or not be fully tightened, which can lead to them falling and pose a potential installation hazard. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an installation mechanism in which fasteners are installed into recessed mounting holes, solving the problem of unstable installation caused by dust accumulation. Furthermore, the operator can easily adjust the emission angle with one hand. This invention also provides a lighting fixture incorporating this installation mechanism.

[0006] In a first aspect, the present invention provides an installation mechanism for installing a lamp body and rotating to adjust the emission angle of the lamp body. The installation mechanism includes a first bracket, a second bracket, a washer assembly, and fasteners. The fasteners connect the first bracket and the second bracket together through the washer assembly.

[0007] The first bracket is fixedly connected to the lamp body. The first bracket is provided with a mounting hole and a groove on the outer periphery of the mounting hole. The groove is used to collect the powder that falls from the mounting hole.

[0008] The second bracket is provided with a through hole, and the fastener includes a rod and a cap, the rod passing through the through hole and being installed in the mounting hole;

[0009] The tightness of the fit between the first bracket and the second bracket can be adjusted by rotating the cap body. The first bracket rotates relative to the lamp body with the rod body as the pivot.

[0010] In some embodiments, the grooves are uniformly distributed on the outer periphery of the mounting hole, and the inner sidewall of the mounting hole is threaded.

[0011] In some embodiments, the groove has one or a combination of a C-shaped structure, a U-shaped structure, a c-shaped structure, or a V-shaped structure.

[0012] In some embodiments, the first support includes a substrate, a cantilever, and a bump. The substrate includes a first base surface and a second base surface arranged relatively parallel to each other. The cantilever extends from the first base surface, the bump extends from the second base surface, and the mounting hole is disposed on the bump.

[0013] In some embodiments, the bump is disposed in the middle of the substrate, and the mounting hole is a through-hole structure that penetrates the bump, or a blind hole structure that does not penetrate the bump.

[0014] In some embodiments, the washer assembly includes a first washer and a second washer, the first washer being disposed between the first bracket and the second bracket, and the second washer being disposed between the second bracket and the cap body.

[0015] In some embodiments, the first washer includes a first ring body and a protrusion disposed on the outer periphery of the first ring body, the first ring body having a first through hole;

[0016] The second washer is a spring washer, and the second washer includes a second ring body. The second ring body has a head end, a tail end, and a second through hole. The head end and the tail end are staggered.

[0017] The rod passes through the second through hole, the through hole and the first through hole in sequence, and is locked in the mounting hole.

[0018] In some embodiments, the second bracket includes a first connecting piece and a second connecting piece arranged perpendicularly to each other, and the through hole is provided in the first connecting piece; the second connecting piece is fixedly connected to an external mounting base.

[0019] Secondly, this utility model provides a lamp, including a lamp body and the aforementioned mounting mechanism, wherein the lamp body is clamped and fastened in the first bracket.

[0020] In some embodiments, the cap body is provided with an adjustment groove, an adjustment tool is inserted into the adjustment groove, and the fastener can be loosened by rotating the cap body. The first bracket drives the lamp body to rotate relative to the second bracket, thereby adjusting the emission angle of the lamp body.

[0021] In summary, this utility model has at least the following advantages:

[0022] 1. The installation mechanism provided by this utility model connects the first bracket and the second bracket together through the washer assembly. During the process of the fastener's rod being inserted into and installed into the mounting hole with a groove on the outer periphery, excess powder will fall into the groove, avoiding the situation where the fastener strips or cannot be completely locked due to powder accumulation in the mounting hole, thus achieving a firm and reliable installation effect.

[0023] 2. The lamp provided by this utility model eliminates the need for a nut structure in the mounting hole. When it is necessary to adjust the emission angle of the lamp body, the first bracket will rotate the first bracket relative to the second bracket by rotating the cap and loosening the fastener. This allows the operator to easily adjust the emission angle of the lamp body with one hand. Attached Figure Description

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] Example 1

[0045] Please see Figures 1-4This embodiment provides an installation mechanism 100 for installing a lamp body 200 and adjusting the emission angle of the lamp body 200. The installation mechanism 100 includes a first bracket 1, a second bracket 2, a washer assembly 3, and a fastener 4. The first bracket 1 is fixedly connected to the lamp body 200, and the second bracket 2 is fixedly connected to an external mounting base such as a ceiling, wall, or floor. The fastener 4 connects the first bracket 1 and the second bracket 2 together through the washer assembly 3.

[0046] The first bracket 1 is provided with a mounting hole 11 and a groove 12. The groove 12 is located on the outer periphery of the mounting hole 11 and is interconnected with the mounting hole 11, and is used to collect the powder that falls into the mounting hole 11.

[0047] The second bracket 2 is provided with a through hole 21; the fastener 4 includes a rod 41 and a cap 42, with the cap 42 disposed at one end of the rod 41. The rod 41 passes through the through hole 21 and is installed in the mounting hole 11.

[0048] In the mounting mechanism 100, the tightness of the fit between the first bracket 1 and the second bracket 2 can be adjusted by rotating the cap 42 of the fastener 4. When the cap 42 of the fastener 4 is loosened, rotating the first bracket 1 will cause the lamp body 200 to rotate relative to the second bracket 2, thereby adjusting the emission / light-emitting angle. After installation or angle adjustment is completed, tightening the cap 42 will keep the relative position of the first bracket 1 and the second bracket 2 fixed, ensuring a stable light-emitting angle.

[0049] When the fastener 4 is loosened or tightened, the rod 41 rotates in the mounting hole 11. Excess powder in the mounting hole 11 will enter the groove 12 that communicates with the mounting hole 11, that is, it will not remain in the mounting hole 11, thus avoiding the stripping of the rod 41 due to powder accumulation in the mounting hole 11, and effectively locking the first bracket 1 and the second bracket 2 together.

[0050] like Figure 2 As shown, grooves 12 are evenly distributed around the outer periphery of mounting holes 11, and threads 111 are provided on the inner wall of mounting holes 11. Correspondingly, fastener 4 is a screw structure, and locking threads are also provided on the end of rod 41 away from cap 42, i.e., the forward end. In this way, when rod 41 enters and locks into mounting hole 11, powder remaining on the inner wall of mounting hole 11 due to the spraying process will be discharged into and collected in groove 12 when rod 41 rotates.

[0051] Since the grooves 12 are evenly distributed around the outer periphery of the mounting holes 11, the powder accumulated on the inner wall of the mounting holes 11 will be discharged into the adjacent grooves 12 as the rod 41 rotates, thus avoiding the slippage or loosening of the connection between the fastener 4 and the first bracket 1 due to the accumulation of powder, thereby improving the production yield.

[0052] Furthermore, the groove 12 has a C-shaped structure, a U-shaped structure, a chamfered structure, or a V-shaped structure. In some embodiments, the groove 12 may be one of a C-shaped structure, a U-shaped structure, a chamfered structure, or a V-shaped structure. In other embodiments, the groove 12 may be a combination of two or more C-shaped structures, U-shaped structures, chamfered structures, or V-shaped structures. In this embodiment, the groove 12 has a U-shaped structure, and multiple grooves 12 surround the outer periphery of the mounting hole 11, and the multiple grooves 12 and the central mounting hole 11 form a quincunx pattern.

[0053] The first support 1 includes a base plate 13, a cantilever 14, and a protrusion 15. The base plate 13 includes a first base surface 131 and a second base surface 132, which are arranged parallel to each other on the upper and lower sides of the base plate 13. The cantilever 14 extends from the first base surface 131 and is used for clamping and connecting with the lamp body 200. The protrusion 15 extends from the second base surface 132. Figure 1 As shown, the cantilever 14 is disposed on the first base surface 131 on the upper side of the substrate 13. Specifically, the cantilever 14 extends from the left and right sides of the first base surface 131 of the substrate 13 and extends into the inward side with a claw, and is fixedly connected to the lamp body 200 by a clamping and fastening structure.

[0054] The bump 15 has an arc-shaped boss structure, and the mounting hole 11 is formed on the bump 15. Specifically, the bump 15 extends from the middle of the substrate 13 in a direction away from the second base surface 132 to form an arc-shaped boss structure.

[0055] In some embodiments, the mounting hole 11 is a through hole structure that runs through the entire protrusion 15. When the rod 41 enters the mounting hole 11 through one of the openings of the mounting hole 11 for rotational installation, most of the accumulated powder is discharged into and contained in the groove 12, and some of the accumulated powder can also be discharged from the other opening of the mounting hole 11.

[0056] In some embodiments, the mounting hole 11 is a blind hole structure that does not penetrate the protrusion 15. When the rod 41 is inserted into the mounting hole 11 for rotational installation, all the accumulated powder on the inner wall of the mounting hole 11 is discharged and contained in the groove 12. Regardless of whether the mounting hole 11 adopts a through hole structure or a blind hole structure, the accumulated powder is contained in the groove 12, avoiding the possibility of stripping when the rod 41 is installed into the mounting hole 11 due to residual powder.

[0057] Reference Figure 1 and Figure 3 The washer assembly 3 includes a first washer 31 and a second washer 32. The washer assembly 3 is used to ensure that the fastener 4 tightly locks the first bracket 1 and the second bracket 2 together. The first washer 31 is disposed between the first bracket 1 and the second bracket 2, and the second washer 32 is disposed between the second bracket 2 and the cap 42 of the fastener 4.

[0058] The first washer 31 includes a first ring body 311 and a protrusion 312 disposed on the outer periphery of the first ring body 311. The first washer 31 has a plate-shaped gear structure. The protrusion 312 can be used to cover the groove 12 and increase the longitudinal friction between the second support 2 and the first support 1. A first through hole 313 is provided on the first ring body 311.

[0059] The second washer 32 includes a second ring 321. Since the second washer 32 is a spring washer, the second ring 321 is not a complete single ring. The second ring 321 is provided with a head end 322, a tail end 323, and a second through hole 324. The head end 322 and the tail end 323 are staggered. The head end 322 can abut against the tail end 323, or there can be an alkaline environment between the head end 322 and the tail end 323.

[0060] Fastener 4 connects the first bracket 1 and the second bracket 2 together via washer assembly 3. Specifically, rod 41 passes sequentially through the second through hole 324, through hole 21, and first through hole 313, and is locked in the mounting hole 11. When locked, cap 42 presses against the second washer 42, causing the head end 322 of the first ring 421 to engage with the tail end 323.

[0061] refer to Figure 1 and Figure 4 The second bracket 2 includes a first connecting piece 22 and a second connecting piece 23. The first connecting piece 22 extends upward from one side of the second connecting piece 23 and is perpendicular to the second connecting piece 23. A through hole 21 is provided in the first connecting piece 22. The second connecting piece 23 is fixedly connected to the external mounting base. Specifically, a fixing hole 231 is provided in the second connecting piece 23, and an expansion screw is passed through the fixing hole 231 to fix the second bracket 2 to the external mounting base.

[0062] The installation mechanism provided in this embodiment connects the first bracket and the second bracket together through a washer assembly. During the process of the fastener's rod being inserted into and installed into the mounting hole with a groove on its outer periphery, excess powder in the mounting hole will fall into the groove, avoiding the situation where the fastener strips or cannot be fully locked due to powder accumulation in the mounting hole, thus achieving a firm and reliable installation effect.

[0063] When adjusting the lamp body, since the nut structure is eliminated, the operator can loosen the fastener with one hand to make the first bracket drive the lamp body to rotate relative to the second bracket, thereby adjusting the emission angle. After installation or angle adjustment is completed, tightening the cap will keep the relative position of the first bracket and the second bracket fixed, ensuring a stable emission angle.

[0064] Example 2

[0065] exist Figures 1-5 Based on reference Figure 6 and Figure 7 This embodiment provides a lighting fixture, which is a wall washer, floodlight, or linear light structure. The lighting fixture includes a lamp body 200 and a mounting mechanism 100 as described in Embodiment 1. The lamp body 200 is clamped and fastened in the first bracket 1.

[0066] The first bracket 1 is fixedly connected to the lamp body 200 by the claws on the cantilever 14. Specifically, the claws on the cantilever 14 located on one side of the substrate 13 first engage in the sliding groove on one side of the lamp body 200, and then the claws on the other side of the cantilever 14 engage in the sliding groove on the other side of the lamp body 200. A locking member passes through the cantilever and locks it in the first bracket, thereby realizing the clamping and fastening fixed connection between the lamp body 200 and the first bracket 1.

[0067] During the installation of the mounting mechanism 100, the fastener 4 sequentially passes through the second through hole 324, the through hole 21, and the first through hole 313, and is then locked into the mounting hole 11. The second bracket 2 is fixedly connected to the external mounting base, specifically by the second connecting piece 23 fitting against the mounting surface of the external mounting base and locking it with expansion screws.

[0068] If the emission angle of the lamp body 200 needs to be adjusted during subsequent use, it can be done by loosening the fastener 4 and then rotating the first bracket 1 to move the lamp body 200 for adjustment.

[0069] Specifically, the fastener 4 has an adjustment groove 421 on the cap 42. The adjustment groove 421 can be a cross groove, an inner square groove, an inner hexagonal groove, or an inner octagonal groove. In this embodiment, the adjustment groove 421 is set as an inner hexagonal groove. The operator uses an adjustment tool 300, such as a hex wrench, with one hand and inserts it into the adjustment groove 421. Rotating the cap 42 will loosen the fastener 4. By slightly turning / rotating the first bracket, the first bracket 1 will cause the lamp body to rotate relative to the second bracket 2, thereby adjusting the emission angle of the lamp body 200.

[0070] like Figure 7 As shown, the lamp body can be rotated 90° clockwise or counterclockwise to adjust the lamp's emission angle.

[0071] The lamp provided in this embodiment eliminates the need for nuts in the mounting holes. When the emission angle of the lamp body needs to be adjusted, the cap is rotated using an adjustment tool and the fastener is loosened. The first bracket will then rotate the lamp body relative to the second bracket, thus completing the operation. The operator can adjust the emission angle of the lamp body with one hand, making it convenient and safe.

[0072] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
