Description

Technical Field

[0001] The invention relates to the technical field of sterilization lamp manufacturing, in particular to an LED photocatalyst sterilization lamp and a preparation method thereof. Background Art

[0002] LED photocatalyst sterilization lamp is an innovative sterilization equipment that combines LED lighting technology and photocatalyst technology. It is widely used in air purification, water treatment, surface disinfection and other fields. It activates photocatalyst materials through ultraviolet light of specific wavelengths emitted by LED to produce active oxygen species with strong oxidizing properties, thereby effectively killing bacteria, viruses, fungi and other microorganisms, and decomposing organic pollutants.

[0003] LED photocatalyst sterilization lamps are mostly composed of a lamp pole, a lamp board and a lamp holder. For sterilization lamps that need to work in a large area, multiple lamp holders are installed on the lamp board. Since the lamp holder is connected on one side, the connection position is prone to instability during the assembly process. Most of the existing ones are locked and fixed one by one by screws, which takes a long time. Secondly, most of the existing straight-rod-shaped lamp poles are threadedly connected to the lamp board. The contact area between the lamp pole and the lamp board is small and is not locked, which is prone to instability. Summary of the invention

The power connection plate is connected to the fixed mounting plate with detachable buckles at multiple positions around the power connection plate, and multiple plug-in slots are provided on the power connection plate, and power plugs are arranged in the plug-in slots. Limit holes connected to the fixed mounting plate and the plug-in slots are provided at corresponding positions.

[0007] Furthermore, the connecting part includes a cylinder, a fixing ring plate is installed on the upper end of the cylinder, a plurality of mounting holes are evenly arranged on the fixing ring plate in the circumferential direction, a circular connecting plate is installed on the lower end of the cylinder, a screw hole is opened in the middle of the circular connecting plate, a tightening screw is threadedly connected to the inner thread of the screw hole, a tightening block is installed at the lower end of the tightening screw, a yield groove is opened in the middle of the lower end of the tightening block, and mounting grooves are opened on both sides of the circular connecting plate.

[0008] Furthermore, the plate group includes a rotating main rod, which is a telescopic structure. One end of the rotating main rod is rotatably installed in the installation groove through a pin shaft, and the other end of the rotating main rod is connected to a rotating support rod through a hinge. The two rotating support rods are snap-fitted.

[0009] Furthermore, a locking groove is provided in the middle of the locking end of one of the rotating support rods, and the locking end of the other rotating support rod is configured as a protrusion matching therewith. The locking ends of the rotating support rods are both provided with waist-shaped holes that pass through from top to bottom, and the waist-shaped holes are connected to the locking groove.

[0010] Furthermore, the fixed mounting plate is a stepped disc structure, a rectangular hole is horizontally penetrated through the inner center position of the upper part of the fixed mounting plate, two rotating support rods are slidably inserted into the rectangular hole, and threaded holes are opened at the center positions of the fixed mounting plate and the power connection plate.

[0011] Furthermore, the aperture of the threaded hole on the power connection plate is smaller than that of the threaded hole on the fixed mounting plate, and a locking bolt is threadedly installed in the two threaded holes. The locking bolt has a stepped structure with a small diameter at the top, a large diameter at the bottom, and a transition from a truncated cone shape in the middle. The upper and lower outer walls of the locking bolt are both provided with threads, and the outer wall of the stepped structure in the locking bolt is smoothly set.

[0012] Furthermore, a plurality of sliding grooves corresponding to the threaded holes and the limit holes are evenly opened along the outer wall of the lower part of the fixed mounting plate, and a limit rod is slidably arranged in the sliding groove. The end of the limit rod close to the limit hole is a U-shaped structure, and a ball is arranged at the end of the limit rod close to the threaded hole. The sliding groove is a stepped groove, and a restoring spring is installed between the limit rod and the inner wall of the sliding groove.

[0013] Furthermore, the present invention also provides an assembly and preparation method of an LED photocatalyst sterilization lamp, comprising the following steps:

[0014] The panel set is unfolded and plugged in: the panel set is rotated and unfolded from the storage state to be plugged in and matched with the fixed installation plate, so as to connect the fixed installation plate with the lamp stand.

Through the cooperation of the fixed mounting plate and the power connection plate in the lamp panel with the locking bolt, multiple lamp heads can be synchronously limited and locked, thereby improving the locking efficiency; at the same time, the cooperation between the two rotating support rods and the connection between the fixed mounting plate and the power connection plate are synchronously locked, thereby greatly improving the stability of the assembly; the triangular structure formed by the cooperation of the tightening screw and the plate group improves the strength of the assembly support of multiple lamp heads and the stability of the installation.

[0020] 2. Due to the structural shape of the locking bolt, the locking bolt rotates upward from bottom to top to synchronously limit and lock multiple lamp holder connections, insert and lock the waist-shaped holes that match the two rotating support rods, and lock the middle thread of the connection between the fixed mounting plate and the power connection plate, thereby preventing the lamp holder from falling off the socket and causing poor contact, and improving the stability of the assembly.

[0021] 3. The tightening screw drives the tightening block to move downward and abut against the upper end of the fixed mounting plate, so that the rotating main rods on both sides are stretched by the tightening force. Finally, the length and angle of the rotating main rod no longer change. The tightening screw in the middle is used to tighten and lock the rotating main rods and rotating support rods on both sides to form a stable triangular structure, thereby improving stability.

[0037] See also Figure 1 The present invention provides a technical solution: an LED photocatalyst sterilization lamp, comprising a lamp holder 1, a lamp board 2 and a lamp holder 3, wherein the lamp holder 1 is detachably provided with a lamp board 2 at the bottom of the lamp holder 1, the lamp board 2 is a circular structure, and a plurality of lamp holders 3 are detachably installed on the lamp board 2 along its circumferential direction.

[0038] See also Figure 1 , Figure 5 , Fig.12 In this embodiment, the lamp holder 1 includes a connecting member 11, and plate groups 12 are symmetrically arranged on both sides of the connecting member 11. The connecting member 11 includes a cylinder 111, and a fixing ring plate 112 is installed on the upper end of the cylinder 111. A plurality of mounting holes 113 are evenly opened on the fixing ring plate 112 along the circumferential direction. The lamp holder 1 can be installed on the wall through the plurality of mounting holes 113 and mounting nails.

[0039] See also Figure 3 , Figure 4 In this embodiment, a circular connecting plate 114 is installed at the lower end of the cylinder 111, a screw hole 115 is opened in the middle of the circular connecting plate 114, a tightening screw 116 is threadedly connected to the screw hole 115, a tightening block 117 is installed at the lower end of the tightening screw 116, and installation grooves are opened on both sides of the circular connecting plate 114.

[0040] See also Figure 6 In this embodiment, the plate group 12 includes a rotating main rod 121, which is a retractable structure. One end of the rotating main rod 121 is rotatably installed in the installation groove through a pin shaft, and the other end of the rotating main rod 121 is connected to a rotating support rod 122 through a hinge, and the two rotating support rods 122 are snap-fitted together; a snap-fitting groove is provided in the middle of the snap-fitting end of one of the rotating support rods 122, and the snap-fitting end of the other rotating support rod 122 is arranged as a protrusion matching therewith, and the snap-fitting ends of the rotating support rods 122 are both provided with waist-shaped holes 123 that pass through from top to bottom, and the waist-shaped holes 123 are connected to the snap-fitting grooves.

[0041] See also Figure 3 , Figure 7 , Fig. 9 In this embodiment, the lamp board 2 includes a fixed mounting plate 21, which is connected to the plate group 12 by penetration. A power connection plate 22 is arranged on the upper end of the fixed mounting plate 21. The power connection plate 22 is detachably connected to the fixed mounting plate 21 at multiple positions around it. A plurality of plug-in slots 23 are provided on the power connection plate 22, and a power plug is provided in the plug-in slot 23. The fixed mounting plate 21 and the plug-in slot 23 are provided with limiting holes 24 connected thereto at corresponding positions. The power connection plate 22 is preliminarily fixed by connecting the fixed mounting plate 21 by snapping, and then the connecting parts of the plurality of lamp heads 3 are passed through the limiting holes 24 of the fixed mounting plate 21 one by one and inserted into the plug-in slot 23 to cooperate with the power plug for connection. Through the threaded cooperation of the tightening screw 116 and the screw hole 115, the tightening screw 116 drives the tightening block 117 to move downward and abut against the upper end of the power connection plate 22. The power connection plate 22 is forced to synchronously press down the fixed installation plate 21, so that the rotating main rods 121 on both sides are stretched by force. After stretching to the extreme, the rotating main rods 121 no longer change, and are tightened and locked by the tightening screw 116 in the middle, so that the rotating main rods 121 and the rotating support rods 122 on both sides form a stable triangular structure, which improves stability. The set cylinder 111 can store the tightening screw 116 without protruding out of the circular connecting plate 114 to hinder the installation of the lamp.

[0042] See also Figure 3 , Figure 8In this embodiment, the fixed mounting plate 21 is a stepped disc structure, and a rectangular hole 211 is horizontally penetrated at the inner center position of the upper part of the fixed mounting plate 21, and the two rotating support rods 122 are slidably arranged in the rectangular hole 211. When not in use, the rotating main rod 121 and the rotating support rod 122 can change their angles, and the rotating main rod 121 can be rotated from an inclined state to a vertical state, and the rotating support rod 122 can be rotated from a horizontal state to a vertical state and located between the two rotating main rods 121, which is convenient for storage, thereby reducing the occupied space; when assembly is required, the rotating support rod 122 is rotated to a horizontal state, and the rotating support rod 122 is inserted into the corresponding rectangular hole 211. At the same time, the inclination angle and length of the rotating main rod 121 also change accordingly. When the rotating support rod 122 enters the fixed mounting plate 21, the protrusion is engaged with the positioning groove.

[0043] See also Figure 8 , Fig. 9 , Fig.10 , Fig.11In this embodiment, a threaded hole 212 is provided at the center of the fixed installation disk 21 and the power connection plate 22. The threaded hole 212 on the power connection plate 22 has a smaller diameter than the threaded hole 212 on the fixed installation disk 21. A locking bolt 25 is threadedly installed in the two threaded holes 212. The locking bolt 25 is a stepped structure with a small diameter at the top, a large diameter at the bottom, and a truncated cone shape in the middle. The upper and lower outer walls of the locking bolt 25 are both provided with threads, and the outer wall of the stepped structure in the locking bolt 25 is smoothly arranged. The inner part of the lower part of the fixed installation disk 21 is along its outer wall A plurality of sliding grooves corresponding to the threaded holes 212 and the limiting holes 24 are evenly provided, and limiting rods 213 are slidably provided in the sliding grooves. The end of the limiting rod 213 near the limiting hole 24 is a U-shaped structure, and a ball 214 is provided at the end of the limiting rod 213 near the threaded hole 212. The sliding groove is a stepped groove, and a restoring spring 215 is installed between the limiting rod 213 and the inner wall of the sliding groove. After the lamp holder 3 is plugged and installed, the locking bolt 25 is screwed into the threaded hole 212 from the bottom of the fixed installation plate 21. Due to the structural shape of the locking bolt 25, the locking bolt 25 is firstly engaged with the plurality of limiting holes. The ball 214 on the positioning rod 213 contacts and pushes the limiting rod 213 into the sliding groove, so that the U-shaped structure of the limiting rod 213 moves into the limiting hole 24. Since the diameter of the connecting part of the lamp holder 3 is larger than the diameter of the light-emitting part, the U-shaped structure of the limiting rod 213 moves out to limit and fix the connecting part of the lamp holder 3 to prevent the lamp holder 3 from falling out of the plug-in slot 23. At the same time, the frustum of the middle part of the locking bolt 25 passes through the waist-shaped holes 123 on the two rotating support rods 122. As the locking bolt 25 continues to rotate and move upward, the locking bolt 25 contacts the straight hole 123. The diameter also gradually becomes larger, thereby locking the two rotating support rods 122 to prevent the rotating support rods 122 from moving laterally in the rectangular hole 211 and as the locking bolt 25 rotates until the top of the locking bolt 25 moves out of the upper threaded hole 212, the fixed mounting disk 21 and the power connection plate 22 are further fixedly connected and locked by the locking bolt 25; thereby, the multiple lamp holders 3, the two rotating support rods 122, and the connection between the fixed mounting disk 21 and the power connection plate 22 are synchronously locked only by the locking bolt 25, thereby greatly improving the stability and efficiency of the installation of the lamp holder 3.

[0044] The assembly and preparation method of the LED photocatalyst sterilization lamp is as follows:

[0045] The rotating support rod 122 is hinged, rotated and unfolded, and then inserted into the corresponding rectangular hole 211. At the same time, the inclination angle and length of the rotating main rod 121 also change accordingly. When the rotating support rod 122 enters the fixed installation plate 21, the protrusion is engaged with the positioning groove.

[0046] The power connection plate 22 is snap-connected with the fixed installation plate 21 for preliminary fixation, and then the connection parts of the multiple lamp holders 3 are passed through the limiting holes 24 of the fixed installation plate 21 one by one and inserted into the plug-in slots 23 to cooperate with the power plug for connection.

[0047] After the lamp holder 3 is plugged in and installed, the locking bolt 25 is screwed into the threaded hole 212 from the bottom of the fixed installation plate 21. Due to the structural shape of the locking bolt 25, the locking bolt 25 first contacts the balls 214 on the multiple limiting rods 213, and pushes the limiting rods 213 into the sliding groove, so that the U-shaped structure of the limiting rod 213 moves into the limiting hole 24. Since the diameter of the connecting part of the lamp holder 3 is larger than the diameter of the light-emitting part, the U-shaped structure of the limiting rod 213 moves out to limit and fix the connecting part of the lamp holder 3, preventing the lamp holder 3 from falling off from the plug-in slot 23; at the same time, the frustum of the middle part of the locking bolt 25 passes through the waist-shaped Hole 123, as the locking bolt 25 continues to rotate and move upward, the diameter of the locking bolt 25 in contact with the waist-shaped hole 123 gradually increases, thereby locking the two rotating support rods 122 to prevent the rotating support rods 122 from moving laterally in the rectangular hole 211 and as the locking bolt 25 rotates until the top of the locking bolt 25 moves out of the threaded hole 212 above, the fixed mounting plate 21 and the power connection plate 22 are further locked and fixed by threads; thereby, the locking of multiple lamp holders 3, the two rotating support rods 122, the fixed mounting plate 21 and the power connection plate 22 are achieved only by the locking bolt 25, which greatly improves the stability and efficiency of the installation of the lamp holder 3.

[0048] The tightening screw 116 cooperates with the thread of the screw hole 115, and the tightening screw 116 drives the tightening block 117 to move downward and abut against the upper end of the power connection plate 22. The power connection plate 22 is forced to simultaneously press down the fixed mounting plate 21, so that the rotating main rods 121 on both sides are stretched by force. After stretching to the extreme, the rotating main rods 121 no longer change, and are tightened and locked by the tightening screw 116 in the middle, forming a stable triangular structure with the rotating main rods 121 and the rotating support rods 122 on both sides, thereby improving stability.
