Description

Technical Field

[0001] The present invention relates to the technical field of waterproof LED street lamps, and particularly to an LED street lamp with good waterproof performance. Background Art

[0002] At present, lamps on the market, such as street lamps, vary in shape and color and are widely used in various corners of the city. They have become essential products for people's lighting and decoration. However, the current street lamps on the market consume a large amount of electricity, have a high cost, are not environmentally friendly, have a short lifespan, and cannot be used for a long time. They often need to be replaced. In addition, the light emitted by some existing lamps is strongly irritating to the eyes, bringing inconvenience to people's lives and work. Moreover, outdoor decorative or lighting street lamps, such as those installed on outdoor lawns, squares, roads, and the periphery of houses, generally require power saving, environmental protection, and the performance of being able to waterproof, prevent ice and snow, and withstand strong sunlight exposure, and have a large irradiation range. At present, the outdoor street lamps on the market have a complex structure, poor sealing performance, and poor waterproof performance. After encountering rain, they are likely to let in water, causing the water to evaporate into water vapor inside the lamp, affecting the brightness and aesthetics of the lamp, and even causing accidents such as electrical short circuits and fires. In addition, the structural design of the existing street lamps is unreasonable, the irradiation range is narrow, and a street lamp needs to be installed at short distances, resulting in a high cost. Therefore, it is very necessary to design a street lamp with a reasonable structure, energy conservation and environmental protection, good waterproof performance, and a wider irradiation range on the existing basis.

[0003] An environmentally friendly and waterproof LED street lamp with the publication number of CN101907253B includes: a lamp module, end caps installed at both ends of the lamp module, and an end cap with a hollow round handle. The lamp module includes two symmetrically structured first light-emitting units and a second light-emitting unit located in the middle of the two first light-emitting units. The two first light-emitting units and the middle second light-emitting unit are connected by a connecting housing. The included angle between the two symmetrically structured first light-emitting units is 100 to 150 degrees. The first light-emitting unit includes a main housing, an aluminum substrate fixed in the main housing, an LED lamp chip welded on the aluminum substrate, a reflector covering the LED lamp chip, and glass located on the reflector. The second light-emitting unit is located in the groove of the connecting housing. The LED street lamp provided by the present invention has a reasonable structural design, is power-saving and environmentally friendly, has a long service life, good sealing and waterproof performance, strong brightness, a wide irradiation range, low cost, and a wide range of applications.

[0004] In the above technical solution, setting two light-emitting units results in a relatively complex structure and cannot fully ensure the sealing effect between components, so improvements are needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages existing in the prior art and propose an LED street lamp with good waterproof performance.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An LED street lamp with good waterproof performance, comprising an installation cover, one end of the installation cover is detachably connected with a connecting bracket, an inner frame assembly is detachably connected inside the installation cover, and a light-transmitting cover is detachably connected to the lower end of the inner frame assembly;

[0008] A lamp group slot is provided at the lower end of the inner frame assembly, a lamp fixture assembly is installed at the top inside the inner frame assembly, the lamp fixture assembly is located above the light-transmitting cover, a plurality of through grooves are equidistantly arranged on the side wall of the inner frame assembly in a circumferential manner, a threaded pipe fitting penetrates through the through groove, a conical member is slidably installed at the top inside the through groove, the conical member abuts against the upper end of the threaded pipe fitting located in the same through groove, both sides of the conical member are rotatably connected with inclined pull rod members, the lower end of the lamp fixture assembly abuts against a square frame member, the square frame member extends into a plurality of through grooves, and the lower ends of a plurality of inclined pull rod members are rotatably connected to the square frame member;

[0009] A sealing mechanism is provided on the square frame member, and the sealing mechanism is connected to the lamp fixture assembly and the inner frame assembly.

[0010] Compared with the prior art, through the setting of the double structure in this application, the lamp fixture assembly is fully arranged inside the installation cover and the inner frame assembly, and the connection and fixation between components are completed through two detachable connection methods. At the same time, with the setting of the gasket structure, the sealing operation can be fully realized, effectively improving the waterproof characteristics of the lamp fixture assembly, avoiding the occurrence of water seepage, ensuring that the lamp fixture assembly can operate in the outdoor environment, and avoiding the situation that water ingress affects lighting.

[0011] Preferably, an installation groove is provided at the lower end of the installation cover, through holes are opened at the four corners of the top inside the installation groove, and card block assemblies are fixed at the four corners of the upper end of the installation groove. The four card block assemblies respectively extend into the four through holes, a through hole is opened on the through hole, a connecting bolt member penetrates through the through hole, and one end of the connecting bolt member is screwed into the card block assembly.

[0012] Furthermore, during actual production and preparation, the card block assembly is inserted into the corresponding through hole, and the connecting bolt member is screwed into the card block assembly to complete the connection and fixation between the installation cover and the inner frame assembly. Moreover, the installation cover will be slightly inclined, so that two of the connecting bolt members will operate downward due to gravity, which helps to improve the connection effect between these two connecting bolt members and the corresponding card block assembly. Also, a rubber plug member can be pressed at the through hole to fully achieve the sealing effect. If rainwater and the like enter between the installation grooves through the through hole, the rainwater will not enter the inner frame assembly.

[0013] Preferably, a second gasket is fixed to the upper end of the inner frame assembly, and four card slots are respectively arranged through the four corners of the second gasket, and the upper end of the second gasket abuts against the bottom in the installation groove.

[0014] Furthermore, during actual production and preparation, squeezing the second gasket between the installation cover and the inner frame assembly can ensure the sealing effect and avoid leakage.

[0015] Preferably, an extrusion member is arranged at the bottom inside the inner frame assembly, and third gaskets are fixed to the opposite sides of the extrusion member and the inner frame assembly respectively, and the two third gaskets abut against each other. A first notch is opened at the lower end of the through groove, and the first notch is arranged on the inner frame assembly, the two third gaskets and the extrusion member. A light-transmitting cover is hermetically abutted against the lower ends of the inner frame assembly and the extrusion member. An inner ring assembly is fixed to the light-transmitting cover, and the inner ring assembly is located inside the extrusion member. A plurality of screwing grooves are equally spaced around the light-transmitting cover. A connecting pipe penetrates through the bottom of the screwing groove, and the connecting pipe penetrates through the inner ring assembly. The threaded pipe fittings penetrate through the first notch, and a pressing plate seal is fixed to one end of the first notch located inside the through groove. A plurality of threaded pipe fittings are respectively arranged at the upper ends of a plurality of connecting pipes. A fastening bolt member penetrates through the connecting pipe, and the fastening bolt member is screwed into the threaded pipe fitting.

[0016] Furthermore, after the inner frame assembly and the installation cover are connected and fixed, the staff can insert the pressing plate seal into the through groove, and at the same time insert the threaded pipe fitting into the first notch. The threaded pipe fitting will squeeze the inner wall of the first notch to make the third gaskets on the extrusion member and the inner frame assembly abut against each other. The staff penetrates the fastening bolt member through the connecting pipe and screws it corresponding to the threaded pipe fitting, which will cause the threaded pipe fitting to drive the pressing plate seal to drop, enabling the pressing plate seal to abut against the bottom in the through groove, making the threaded pipe fitting and the connecting pipe correspond, and at the same time causing the light-transmitting cover to move towards the inner frame assembly, fully realizing the relative movement between the light-transmitting cover and the inner frame assembly, and improving the firmness of the connection between the light-transmitting cover and the inner frame assembly.

[0017] Preferably, a first gasket is fixed around the upper end of the light-transmitting cover, and two sealing rings are fixed around the lower end of the inner frame assembly, and both sealing rings abut against the first gasket. The first gasket abuts against the lower end of the inner frame assembly and the lower end of the extrusion member.

[0018] Furthermore, when the light-transmitting cover and the inner frame assembly move relatively, it will cause the first gasket and the sealing rings to be fully squeezed and deformed, effectively filling the corresponding gaps and effectively preventing penetration.

[0019] Preferably, a lifting rod penetrates through the top of the through groove, and the lower end of the lifting rod is fixedly connected to one end of the square member extending into the through groove.

[0020] Furthermore, the function of the lifting rod can ensure the stability of the lifting of the square member. During actual production and preparation, the square member has a square structure. At the same time, a plurality of plate bodies are arranged at equal intervals along the outer edge of the square, and the plate bodies extend into the through groove, which can ensure the lifting of the square member.

[0021] Preferably, the sealing mechanism includes a plurality of connecting frame components slidably mounted on the square member. One side of the connecting frame component is rotatably sleeved with a rotating shaft. A second notch is opened on one side of the lower end of the square member corresponding to the rotating shaft. A swing rod is rotatably sleeved in the second notch. The upper end of the swing rod abuts against the lower end of the lamp assembly, and the lower end of the swing rod abuts against the rotating shaft. The upper ends of the plurality of connecting frame components are jointly fixed with a bearing plate, and a conical sealing ring member is fixed on the upper end of the bearing plate. The conical sealing ring member extends between the lamp assembly and the inner frame assembly.

[0022] Furthermore, as the threaded pipe fitting squeezes the conical member, the conical member can drive the inclined pull rod member to make the square member rise, which can make the swing rod abut against the lower end of the lamp assembly, and can make the lamp assembly deflect. The deflection of the lamp assembly will make the swing rod abut against the rotating shaft and push the bearing plate and the conical sealing ring member to rise. The conical sealing ring member is annularly arranged, and can make the conical sealing ring member insert between the lamp assembly and the inner frame assembly to seal the gap.

[0023] Preferably, a pressing ring member and a top ring member are respectively fixed on the opposite sides of the inner ring assembly and the pressing member. A plurality of insertion rods are arranged at equal intervals on the upper end of the pressing ring member. A plurality of insertion slots are arranged at equal intervals on the lower end of the top ring member. The plurality of insertion rods respectively extend into the plurality of insertion slots. Rubber pads are fixed on the opposite sides of the top ring member and the pressing ring member. The rubber pad at the lower end penetrates through the plurality of insertion rods, and the plurality of insertion slots penetrate through the rubber pad at the upper end.

[0024] Furthermore, as the light-transmitting cover and the inner frame assembly move relative to each other, the pressing ring member and the top ring member can move relative to each other. During preparation, both the pressing ring member and the top ring member are annularly arranged, which can effectively seal and prevent penetration and leakage. That is, when water vapor enters through the screwing groove, the water vapor will be sealed in the inclined opening, ensuring the dryness inside the lamp assembly and preventing water vapor from entering.

[0025] Preferably, an inclined opening is provided between the inner ring assembly and the pressing member, and the inclined opening is bent.

[0026] Furthermore, the bending setting can effectively achieve the isolation operation.

[0027] Preferably, a plurality of through holes are opened at the bottom of the installation groove.

[0028] Furthermore, the moisture entering the installation groove can be discharged through the through holes, and a filter net component is arranged in the through holes to prevent impurities from entering.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. In this application, two detachable connections are used to complete the connection and fixation between the installation cover, the inner frame assembly, and between the inner frame assembly and the light-transmitting cover. Moreover, the position of the lamp assembly can be effectively limited. At the same time, during the detachable process, the extrusion of the sealing component can be fully ensured to improve the sealing effect, prevent moisture flow, fully ensure the dryness of the position of the lamp assembly, and improve the waterproof performance;

[0031] 2. During actual production and preparation, the block component is inserted into the corresponding card slot, and the connecting bolt component is screwed into the block component to complete the connection and fixation between the installation cover and the inner frame assembly. Moreover, the installation cover may be slightly inclined, which can cause two of the connecting bolt components to operate downward due to gravity, helping to improve the connection effect between these two connecting bolt components and the corresponding block components. Additionally, the rubber plug component can be pressed at the through hole to fully achieve the sealing effect. If rainwater or the like enters through the through hole into the installation groove, the rainwater will not enter the inner frame assembly;

[0032] 3. The threaded pipe fitting presses the conical part, which can drive the inclined pull rod part to make the square frame part rise, enabling the swing rod to contact the lower end of the lamp assembly, causing the lamp assembly to deflect. The deflection of the lamp assembly will make the swing rod contact the rotating shaft and push the bearing plate and the conical sealing ring part to rise. The conical sealing ring part is annularly arranged, enabling the conical sealing ring part to be inserted between the lamp assembly and the inner frame assembly to seal the gap;

[0033] 4. The relative movement between the light-transmitting cover and the inner frame assembly can make the pressing ring part and the top ring part move relatively. During preparation, both the pressing ring part and the top ring part are annularly arranged, which can effectively seal and prevent penetration and leakage. That is, when moisture enters through the screwing groove, the moisture will be sealed in the inclined opening, ensuring the dryness inside the lamp assembly and preventing moisture from entering.

During preparation, both the pressure ring member 26 and the top ring member 32 are annularly arranged, which can effectively achieve sealing and avoid penetration and leakage. That is, when water vapor enters through the screw engagement groove 16, the water vapor will be sealed in the inclined opening 24, ensuring the dryness inside the lamp assembly 13 and preventing water vapor from entering. There is an inclined opening 24 between the inner ring assembly 40 and the extrusion member 22, and the inclined opening 24 is bent. The bending setting can effectively achieve the isolation operation.

[0051] In the present invention, through the connection bracket 3, it can be effectively fixed by the roadside and the lighting operation can be effectively realized. The connecting bolt member 8 is screwed into the block assembly 7 to complete the connection and fixation of the mounting cover 1 and the inner frame assembly 4. Moreover, the mounting cover 1 will be slightly inclined, so that two of the connecting bolt members 8 will move downward due to gravity, which helps to improve the connection effect between these two connecting bolt members 8 and the corresponding block assembly 7. Also, the rubber plug member can be pressed at the through hole 9 to fully achieve the sealing effect. If rainwater or the like enters between the mounting grooves 2 through the through hole 9, the rainwater will not enter the inner frame assembly 4.

[0052] By rotating and screwing the fastening bolt member 10, the connection and fixation between the light-transmitting cover 11 and the inner frame assembly 4 can be realized. When the fastening bolt member 10 is screwed into the threaded pipe member 21, the threaded pipe member 21 can be made to contact the conical member 29, enabling the inclined pull rod member 28 to drive the square frame member 25 to rise, so that the square frame member 25 contacts the lower end of the lamp assembly 13. At the same time, the swing rod 34 can push the rotating shaft 38, causing the connecting frame assembly 39 to push the bearing plate 35 and the conical sealing ring member 36 to rise, effectively achieving the plugging and sealing between the lamp assembly 13 and the inner frame assembly 4.

[0053] Through the action of the rubber pad 30, the sealing operation can be effectively carried out.
