[0034] Combine the following Figure 1-2 The lamp installation structure provided by the present invention is described.

[0035] like Figure 1 and Figure 2 As shown, the lamp installation structure 1 provided by the present invention includes a limit member 11, a socket 12 and a fixing assembly 13; the socket 12 is used to be arranged on the base 3 and connected to the lamp pole 2, and the socket 12 is constructed with a first notch 121, and the first notch 121 is used to be passed through by the protrusion 31 of the base 3; the fixing assembly 13 is located above the first notch 121 and is arranged around the outer periphery of the lamp pole 2, and the fixing assembly 13 is constructed with a fixing hole 131, and the fixing hole 131 is used to be passed through by the protrusion 31; the limit member 11 is located above the fixing assembly 13, and is used to be detachably arranged on the protrusion 31, and the limit member 11 is movable along the axial direction of the protrusion 31, so that by adjusting the position of the limit member 11, the base 3 and the fixing assembly 13 clamp and fix the socket 12, so as to limit and fix the lamp pole 2.

[0036] In this embodiment, the lamp installation structure 1 is generally used to fix the lamp pole 2 on the ground. Specifically, before installing the street lamp, it is usually necessary to bury the installation foundation, that is, the base 3, in the ground; the base 3 is usually constructed with a protrusion 31 such as a bolt to install and fix the lamp pole 2; when installing the lamp pole 2, the holder 12 and the fixing component 13 are stacked on the base 3 in sequence; the protrusion 31 passes through the first notch 121 and the fixing hole 131 in sequence, and cooperates with the limiting member 11 to limit the fixing component 13, the limiting member 11 abuts the fixing component 13, and the fixing component 13 abuts the holder 12, so that the holder 12 is clamped between the base 3 and the fixing component 13, and then the lamp pole 2 connected to the holder 12 is fixedly installed on the ground; at the same time, by setting the fixing component 13, when the position of the protrusion 31 deviates, the fixing component 13 can be adjusted or replaced so that the protrusion 31 can pass through the fixing hole 131, so that the holder 12 is clamped and fixed by the limiting member 11 and the fixing component 13, which is convenient for construction personnel to carry out construction.

[0037] The lamp installation structure 1 of the present invention, by movably connecting the fixing component 13 to the protrusion 31, and limiting the fixing component 13 by the limiting piece 11 on the protrusion 31, so that the fixing component 13 and the base 3 clamp and fix the holder 12 on the base 3, and then the lamp pole 2 on the holder 12 is installed and fixed to the ground; at the same time, the fixing component 13 is adjusted or replaced according to the size and position of the protrusion 31, so that the fixing hole 131 on the fixing component 13 can allow the protrusion 31 to pass through and connect with the limiting piece 11, so that the holder 12 is clamped and fixed by the limiting piece 11 and the fixing component 13, so as to avoid the position, size or angle deviation of the protrusion 31 affecting the installation of the lamp pole 2, and effectively solves the problem of deformation or misalignment of the anchor bolts of the lamp pole cage foundation in the prior art, which seriously affects the installation and fixation of the lamp pole.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, when there are more than two protrusions 31 constructed on the base 3, the lamp mounting structure 1 includes more than two limiting members 11, and the more than two limiting members 11 are used to correspond one-to-one to the more than two protrusions 31. The socket 12 is constructed with more than two first notches 121, and the more than two first notches 121 are used to correspond one-to-one to the more than two protrusions 31. The fixing component 13 is constructed with more than two fixing holes 131, and the more than two fixing holes 131 are used to correspond one-to-one to the more than two protrusions 31.

[0039] In this embodiment, when there are more than two protrusions 31 constructed on the base 3, more than two limiting members 11, more than two first notches 121 and more than two fixing holes 131 corresponding to the protrusions 31 are provided. Each protrusion 31 can pass through the corresponding first notch 121 and the fixing hole 131, and cooperate with the limiting member 11 and the fixing assembly 13 to clamp and fix the base 12. When clamping and fixing, the force on each protrusion 31 is more evenly dispersed, the clamping and fixing of the base 12 is more firm and reliable, and it is also beneficial to extend the service life of each component.

[0040] In a specific embodiment, Figure 2 As shown, a plurality of protrusions 31 are evenly arranged on the base 3 along a ring shape, and the plurality of protrusions 31 pass through a plurality of first notches 121 corresponding to the holder 12, and enclose the holder 12 in the middle of the ring shape enclosed by the protrusions 31, thereby further limiting the horizontal position of the holder 12, and cooperating with the limiter 11 and the fixing assembly 13 to limit the vertical position of the holder 12, so that the lamp pole 2 is more firmly installed and fixed on the base 3.

[0041] In some embodiments, Figure 1 and Figure 2As shown, the fixing assembly 13 includes more than two fixing members 133 , each fixing member 133 is provided with at least one fixing hole 131 , and the more than two fixing members 133 are evenly arranged around the outer circumference of the lamp pole 2 .

[0042] In this embodiment, a plurality of fixing members 133 are provided to form a fixing assembly 13. Before the lamp pole 2 is installed and fixed, the fixing assembly 13 can be disassembled into the fixing members 133 for carrying and transportation. When the lamp pole 2 is installed and fixed, each fixing member 133 can be installed on the corresponding protrusion 31 respectively, without the need to connect the entire fixing assembly 13 from the end of the lamp pole 2 away from the base 3 to the lamp pole 2 and then move it to a position close to the base 3, thereby making the installation and construction more convenient and flexible. At the same time, each fixing member 133 can be adjusted or replaced individually so that the fixing hole 131 on the fixing member 133 can adapt to the corresponding protrusion 31, which is more convenient to solve the problem of deformation or misalignment of the protrusion 31.

[0043] Optionally, each fixing member 133 may include a fixing hole 131, so that each fixing member 133 can be adjusted or replaced individually, and the fixing hole 131 on each fixing member 133 can be adapted to the corresponding protrusion 31, which is more flexible and convenient; or, each fixing member 133 may include multiple fixing holes 131, so as to reduce the number of fixing members 133 to be installed and improve construction efficiency. The fixing holes 131 on the actual fixing member 133 can be adjusted according to actual needs.

[0044] Specifically, Figure 2 As shown, the fixing assembly 13 can be an annular structure composed of multiple fan-shaped fixing parts 133, each fan-shaped fixing part 133 is evenly provided with multiple fixing holes 131 along the annular circumference, and each fan-shaped fixing part 133 can be individually disassembled and assembled to the corresponding protrusion 31.

[0045] Optionally, the plurality of fixing members 133 do not need to be connected to each other, but only need to be arranged corresponding to the protrusions 31 and evenly distributed on the protrusions 31 in a ring-shaped arrangement, with a lamp pole hole 132 for mounting the lamp pole 2 being formed in the middle of the ring.

[0046] In some embodiments, Figure 2 As shown, two or more fixing members 133 are connected in sequence to form a lamp pole hole 132 for the lamp pole 2 to pass through.

[0047] In this embodiment, more than two fixing members 133 are connected in sequence, and the fixing members 133 are fixed to each other, so that the entire fixing assembly 13 is more firm and reliable.

[0048] In some embodiments, Figure 1As shown, the fixing member 133 includes a first portion 1331 and a second portion 1332 connected to each other. The first portion 1331 is disposed on the holder 12 , and the second portion 1332 protrudes downward from the first portion 1331 . The second portion 1332 is used to abut against the base 3 .

[0049] In this embodiment, the projections of the first part 1331 and the socket 12 on the base 3 partially overlap. By setting the first part 1331 on the socket 12 and the cover above the socket 12, the first part 1331 is abutted against the socket 12 under the limit structure of the limit member 11 to cooperate with the base 3 to clamp and fix the socket 12; at the same time, a downwardly protruding second part 1332 is provided on the first part 1331, and the second part 1332 can abut against the base 3 when the first part 1331 abuts against the socket 12 to support the fixing member 133, thereby making the fixing member 133 more stable and reliable and increasing the structural strength.

[0050] In a specific embodiment, Figure 1 As shown, the cross-section of the fixing member 133 is L-shaped, the first part 1331 is the long side of the L-shaped structure, and is horizontally arranged on the holder 12. The protrusion 31 is passed through the fixing hole 131 on the first part 1331, and cooperates with the limiting member 11 to limit the first part 1331, so that the first part 1331 abuts against the holder 12, and the second part 1332 is the short side of the L-shaped structure. The second part 1332 is arranged at the end of the first part 1331 away from the lamp pole 2, and abuts downward against the base 3, so that the fixing member 133 can be stably buckled on the stepped structure formed by stacking the holder 12 and the base 3, so as to cooperate with the base 3 to clamp and fix the holder 12.

[0051] Specifically, in some embodiments, Figure 2 As shown, the holder 12 is a flange, the center of the flange is used to connect the lamp pole 2 , and the flange has a plurality of first notches 121 sequentially arranged along the circumference of the lamp pole 2 .

[0052] In this embodiment, the holder 12 is a flange, and a plurality of first notches 121 are arranged in sequence along the annular edge of the flange. The base 3 is provided with a plurality of protrusions 31 corresponding to the first notches 121. When installing and fixing the lamp pole 2, the plurality of protrusions 31 pass through the first notches 121 to surround the flange, thereby further limiting the horizontal position of the holder 12, and cooperating with the limiter 11 and the fixing assembly 13 to limit the vertical position of the holder 12, so that the lamp pole 2 is more firmly installed and fixed on the base 3.

[0053] Specifically, in some embodiments, Figure 2 As shown, the first notch 121 is a U-shaped notch opened away from the lamp pole 2 .

[0054] In this embodiment, the first notch 121 is a U-shaped notch, which is arranged at the edge of the socket 12, with the opening facing the outside of the socket 12. When there is a certain deviation in the position and angle of the protrusion 31, the protrusion 31 can still be inserted into the U-shaped notch without replacing the socket 12, making the installation and construction of the socket 12 more convenient and flexible.

[0055] Specifically, in some embodiments, Figure 1 and Figure 2 As shown, the protrusion 31 is a bolt, and the limiting member 11 is a nut matched with the bolt.

[0056] In this embodiment, the bolt is sequentially passed through the first notch 121 and the fixing hole 131, and the nut is installed on the portion of the bolt protruding from the fixing hole 131. The lower side of the nut abuts against the fixing component 13 to limit the fixing component 13, so that the fixing component 13 cooperates with the base 3 to clamp the fixing socket 12, and it is also convenient to disassemble and assemble the fixing component 13, so as to install and maintain the lamp mounting structure 1.

[0057] In a specific embodiment, the bolt is an M42 bolt, and the nut is an M42 nut adapted to the bolt. The standard size of the thread corresponding to the M42 bolt and the M42 nut is a diameter of M42, the type of thread is M42×2, and the rod length is usually 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc. Different sizes are selected according to different application scenarios. The M42 bolt and the M42 nut can be made of steel, stainless steel, copper, etc., and different materials can be selected for use according to different actual needs.

[0058] Optionally, a nut gasket may be installed between the nut and the fixing assembly 13 .

[0059] Specifically, in some embodiments, Figure 2 As shown, the fixing hole 131 is a waist-shaped hole. By setting the fixing hole 131 as a waist-shaped hole, the length direction of the waist-shaped hole can be along the tangential direction or axial direction of the annular fixing component 13. When the position or size of the protrusion 31 has a certain deviation, the waist-shaped hole can provide a certain fault tolerance, so that the protrusion 31 can still pass through the fixing hole 131, thereby facilitating the connection between the protrusion 31 and the limiting member 11, so as to limit the fixing component 13, making the installation construction more convenient and flexible.

[0060] In other embodiments, the fixing hole 131 may also be a strip hole or a circular hole. For example, the fixing hole 131 may be a strip hole, and the length direction of the strip hole can provide a certain tolerance for the construction of the protrusion 31. When the position or size of the protrusion 31 has a certain deviation, the protrusion 31 can still pass through the fixing hole 131; or, the fixing hole 131 may also be a circular hole, the size of the circular hole is slightly larger than the cross-section of the protrusion 31 perpendicular to the axial direction, and slightly smaller than the bottom surface of the limiting member 11. The circular hole can provide tolerance in all directions for the construction of the protrusion 31. When the position or size of the protrusion 31 has a certain deviation, the protrusion 31 can still pass through the fixing hole 131, thereby facilitating the connection between the protrusion 31 and the limiting member 11 to limit the fixing component 13.

[0061] On the other hand, Figure 1 and Figure 2 As shown, the present invention further provides a street lamp, comprising a lamp pole 2 and a lamp installation structure 1 as described in any of the above embodiments. By adopting the lamp installation structure 1 described in the above embodiments, the street lamp of the present invention also has the above lamp installation structure 1, which will not be described in detail here.

[0062] In this embodiment, the lamp pole 2 is fixed on the street lamp foundation through the lamp mounting structure 1, and various lamps such as street lights, traffic lights, and advertising lights can be installed on the lamp pole 2 according to actual needs.

[0063] In some embodiments, Figure 1 and Figure 2 As shown, a plurality of reinforcing plates 21 are provided on the lamp pole 2, and the plurality of reinforcing plates 21 are arranged at intervals along the circumference of the lamp pole 2, one side edge of each reinforcing plate 21 is fixedly connected to the holder 12, and the other adjacent side edge is fixedly connected to the lamp pole 2; a second notch 134 is constructed at the position of the fixing component 13 corresponding to the reinforcing plate 21, and the second notch 134 is used to avoid the reinforcing plate 21.

[0064] In this embodiment, by setting one side edge of the reinforcing plate 21 to be fixedly connected to the holder 12 and the other adjacent side edge to be fixedly connected to the lamp pole 2, the connection between the lamp pole 2 and the holder 12 is supported and strengthened, so that the lamp pole 2 can be more stable; at the same time, by setting a plurality of reinforcing plates 21 at circumferential intervals at the lamp pole 2, the force on the lamp pole 2 in all directions in the horizontal direction can be made more uniform, which can better prevent the lamp pole 2 from tilting, making the lamp pole 2 more stable and reliable.

[0065] It should be noted that, in other embodiments, the lamp mounting structure 1 can also be used in other scenarios. For example, the lamp mounting structure 1 can be used to set up different lamps such as household hanging lamps or chandeliers. The lamp can be fixed only by setting up structures such as the base 3, the limiter 11, the socket 12 and the fixing assembly 13.

[0066] The above described embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the embodiments. Those skilled in the art may understand and implement the embodiments without creative effort.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
