Description

Technical Field

[0001] This invention relates to a base for landscape lighting fixtures. Background Technology

[0002] Landscape lighting is an important component of urban beautification projects. Landscape lighting equipment, especially light show equipment, needs to be accurately installed in the designated locations according to the design drawings. Some fixtures require direct installation in the designated locations using brackets, such as mountain light shows. To avoid damage to the mountain, holes are often drilled in the soil or rock layers, and the light fixture brackets are directly installed in the holes, as shown in publication number CN209926174U. However, this installation method is relatively simple, relying mainly on manual labor and small equipment. The verticality of the drilling is difficult to guarantee. If the drilling is off-center, it is usually impossible to re-drill in the same location due to the influence of the original hole. Landscape lighting fixtures have high requirements for location, and modifying the specific location requires redesign. Furthermore, even if the installation location is accurate, because this construction method does not involve soil hardening, the brackets inserted into the soil are prone to tilting during long-term use, causing the fixtures to deviate from their designed positions and affecting the landscape lighting effect. Summary of the Invention

[0003] To address the above shortcomings, the present invention aims to provide an adjustable mounting base for landscape lighting fixtures, which allows for adjustment when the bracket is tilted relative to a predetermined target.

[0004] In response, the present invention provides a landscape lighting fixture base, comprising a bracket for mounting the lighting fixture and a fixing device for fixing the bracket. The fixing device includes a groove, at least a portion of which has a diameter larger than that of the bracket, allowing the bracket to deflect radially within the groove. The bracket is fitted with a limiting ring, the outer wall of which contacts the inner wall of the groove, and the diameter of the limiting ring is adjustable.

[0005] Furthermore, the outer diameter of the lower end of the bracket is equal to the inner diameter of the groove, and the diameter of the bracket body is smaller than the inner diameter of the groove.

[0006] In the above embodiment, the groove is provided with a lower stepped surface, the lower end of the bracket is provided with a retaining ring, the retaining ring is provided with a plurality of annular protrusions that cooperate with the lower stepped surface, and an adjustment slot is provided between the annular protrusions. The retaining ring cooperates with the limiting ring to fix the bracket in the groove.

[0007] Furthermore, the fixing device includes a plate and a cylinder, the cylinder is vertically fixed to the lower surface of the plate, the groove penetrates the plate and extends into the cylinder, the plate or cylinder is provided with an upper stepped surface, and the lower surface of the collar mates with the upper stepped surface.

[0008] Furthermore, the collar is a T-shaped nut, and the outer wall of the bracket is provided with threads that mate with the T-shaped nut.

[0009] Furthermore, the T-shaped nut includes a polygonal column and a stepped disc, the stepped disc engaging with the upper stepped surface.

[0010] Furthermore, the T-shaped nut includes several arc-shaped adjusting blocks surrounding the outside of the T-shaped nut, with the adjusting blocks and the outer wall of the T-shaped nut having opposing screws fixed to each other, and the two ends of the threaded tube being threadedly connected to a corresponding pair of screws.

[0011] Furthermore, the arc-shaped adjustment blocks are evenly distributed on the same circumference.

[0012] Furthermore, the bottom of the groove is provided with a slot, the slot is provided with a block that cooperates with the retaining ring, and an elastic return device is provided below the block. The width of the block is greater than the width of the lower step surface, so that when the retaining ring moves down, the retaining ring pushes the block down. The side opposite to the retaining ring and the block is provided with a slope or arc surface.

[0013] The beneficial effects of this invention are as follows:

[0014] (1) In a specific embodiment of the present invention, the bracket is fixed in the groove. When the construction deviation or the fixing device is tilted to a certain extent after long-term use, the threaded tube is adjusted in the opposite direction. That is, when the fixing device is offset by an angle in a certain direction, one or more threaded tubes in the corresponding direction are adjusted to shorten the distance between the adjusting block and the bracket, and the distance between the adjusting block on the opposite side and the bracket is shortened, so that the verticality of the bracket meets the requirements.

[0015] (2) The groove of the present invention is provided with upper and lower stepped surfaces, and the bracket is provided with a T-shaped nut and a retaining ring. The T-shaped nut and the retaining ring fix the bracket in the groove of the fixing device, which facilitates the disassembly of the bracket. The lighting effect of landscape lighting is adjusted after installation, but the actual effect usually does not meet the design effect. It takes repeated adjustments to meet the requirements, which may require adjustments to some points. The above solution of the present invention can make it very convenient to adjust the lighting fixtures. Attached Figure Description

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] Reference Figures 1 to 4 As shown, a landscape lighting fixture base of the present invention includes a fixing device for fixing the base to the ground. The fixing device includes a cylindrical body 1 inserted into the soil or rock and a plate 2 fixed to the ground. The cylindrical body 1 is vertically fixed to the plate 2. The fixing device has a groove 3, which is a combination of multiple cylinders. The upper and lower ends of the groove 3 have stepped surfaces. A cylindrical support 4 is fixed in the groove 3. The support 4 is used to install the lighting fixture. A certain gap is provided between the support body 401 and the groove 3. The lower end of the support 4 contacts the inner wall of the groove 3 or leaves a gap smaller than the distance between the support body 401 and the groove 3. The support body 401 can be radially deflected in the groove 3. An adjustable diameter limiting ring is sleeved on the support body 401. The limiting ring is a T-nut 5. The outer wall of the support 4 is provided with threads that cooperate with the T-nut 5. The T-nut 5 includes a polygonal column body 501 and a stepped platform. The bracket 4 has a stepped plate 502 and several arc-shaped adjusting blocks 503 surrounding the outside of the T-shaped nut 5. The outer wall of the adjusting block 503 contacts the inner wall of the groove 3 above the upper stepped surface 301. The adjusting block 503 and the outer wall of the T-shaped nut 5 are fixed with opposing screws 504. The two ends of the threaded tube 505 are threadedly connected to a pair of corresponding screws 504 between the outer walls of the adjusting block 503 and the T-shaped nut 5. The threads at both ends of the threaded tube 505 are reverse threads. The lower end of the bracket 4 is provided with a retaining ring 6. The retaining ring 6 is provided with several annular protrusions 601 that cooperate with the lower stepped surface 302. An adjusting slot 602 is provided between the annular protrusions 601. When the bracket 4 is inserted into the groove 3, the retaining ring 6 is locked on the lower stepped surface 302. Rotating the T-shaped nut 5 makes the lower surface of the T-shaped nut 5 fit tightly with the upper stepped surface 301. Rotating the threaded tube 505 makes the outer wall of the adjusting block 503 fit tightly with the inner wall of the groove 3. In this embodiment, the cylinder 1 can be directly pressed into the soil, or a hole can be drilled first and then the cylinder 1 can be installed into the hole.

[0024] In the above embodiments, reference is made to Figure 2 As shown, the arc-shaped adjustment blocks 503 are evenly distributed on the same circumference.

[0025] In the above embodiments, reference is made to Figure 1 and Figure 4 As shown, in order to prevent the retaining ring 6 from loosening from the step surface, a limiting protrusion 303 is provided on the step surface, and a limiting groove 603 is provided on the retaining ring 6. The limiting protrusion 3 is inserted into the limiting groove 603 to prevent the bracket 4 from loosening from the lower step surface 302.

[0026] In the above embodiments, reference is made to Figure 1 and Figure 4 As shown, the bottom of the groove 3 is provided with a slot 7, and the slot 7 is provided with a locking block 8 that cooperates with the locking ring 6. The locking block 8 is set close to the inner wall of the groove 3, and a certain gap is provided between the locking block 8 and the inner wall of the groove 3. An elastic return device 9, such as a spring, is provided below the locking block 8. The upper end of the locking block 8 is an arc-shaped end face 801, which contacts the lower step surface 302. The distance between the locking block 8 and the center line of the cylinder 1 is less than the distance between the inner side of the lower step surface 302 and the center line of the cylinder 1. The side of the locking ring 6 that contacts the locking block 8 is provided with a slope or an arc surface. In this embodiment, the cylinder 1 can be formed in sections, and the internal structure of the groove 3 is assembled and then connected together by welding.

[0027] The installation process for the aforementioned base is as follows:

[0028] (1) Determine the installation location according to the construction drawings, level the land near the location, and use a small press to press part of the cylinder 1 into the soil so that the plate 2 is flush with the ground.

[0029] (2) Place the bracket 4 into the cylinder 1. The retaining ring 6 retracts first, and after passing the lower step surface 302, the retaining ring 6 pushes the retaining block 8 down. At the same time, the retaining ring 6 rebounds and cooperates with the lower step surface 302 to fix it. Rotate the T-nut 5 and tighten it on the upper step surface 301 so that the T-nut 5 and the retaining ring 6 fix the bracket 4 on the base.

[0030] (3) Rotate the threaded tube 505 so that the distance between the adjusting block 503 and the bracket 4 is equal and they are tightly fitted to the inner wall of the groove 3;

[0031] (4) Measure the verticality of bracket 4. When there is a deviation in the verticality of bracket 4, adjust the threaded tube 505 in the deflection direction so that the verticality of bracket 4 meets the requirements and the adjusting block 503 is tightly fitted with the inner wall of groove 3.

[0032] (5) When bracket 4 needs to be removed, first remove the light fixture, loosen the adjusting block 503 from the inner wall of the groove 3, rotate the T-nut 5, and press down on bracket 4. The retaining ring 6 first pushes the retaining block 8 down. When it continues to go down, the retaining block 8 can no longer go down. The retaining ring 6 retracts and slides down along the inner side of the retaining block 8. The retaining block 8 rebounds and contacts the lower platform. When the bracket 4 is pulled up, the retaining block 8 blocks the lower step surface 302, and the bracket 4 rises smoothly. Of course, a spring can also be installed at the bottom of the groove 3, and the spring force after pressing can be used to directly pop the bracket 4 outward.

[0033] In the above embodiment, an auxiliary cylinder 10 inserted into the mountain can also be provided at a certain distance to the side of the base. The auxiliary cylinder is connected to the base to prevent the cylinder from tilting. When the base is tilted, the auxiliary cylinder 10 can also be provided in the opposite direction of the tilt.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
