The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0037] The present invention provides an explosion-proof platform lamp 10, such as Figure 1 and Figure 2 As shown, it includes: a three-way base 100, a lamp 200, a power supply assembly 300 and a connecting pipe 400, the interior of the three-way base 100 is provided with a receiving cavity 110, and the three-way base 100 is provided with two open ports 120 and a support port 130 (such as Figure 3As shown), the two open ports 120 are connected to the accommodating cavity 110.
[0038] The power supply assembly 300 is received in the accommodating cavity 110, the lamp 200 is installed at one of the open ports 120, and a wiring terminal cover 140 (such as Figure 1 and Figure 3 As shown in FIG. 1 , the terminal cover 140 is installed at the other open port 120. The connecting pipe 400 is installed on the supporting port 130, and the connecting pipe 400 is sleeved on the external lamp pole. The connecting pipe 400 of the present invention includes a curved pipe style structure (such as Figure 1 As shown) and straight tube style structure (as Figure 4 As shown in the figure, different styles of structures correspond to different installation angles. Therefore, during the installation process, the staff selects the style of the connecting pipe 400 according to the actual lighting angle requirements to meet the angle adjustment requirements. It is also worth noting that when the style of the connecting pipe 400 is changed, the connection relationship between the lamp 200 and the three-way base 100 can also be changed accordingly, which can also play a role in adjusting the lighting angle.
[0039] like Figure 2 As shown, the power supply assembly 300 includes: a lead wire 310, a terminal 320 and a wire crimping clamp 330. The lead wire 310 passes through the connecting pipe 400 and extends from the support port 130 to the accommodating cavity 110. The wire crimping clamp 330 is used to press and fix the lead wire 310. The lead wire 310 is electrically connected to the terminal 320, and the terminal 320 is electrically connected to the lamp 200.
[0040] Preferably, the support port 130 is provided with a guide extension block 131 (such as Figure 5 As shown in the figure, the guide extension block 131 is located in the accommodating cavity 110, and the wire clamp 330 cooperates with the guide extension block 131 to clamp and limit the lead wire 310. The guide extension block 131 is provided with a longitudinal screw hole 132 and a transverse screw hole 133 adapted to the wire clamp 330. During use, since the connection relationship between the lamp 200 and the three-way base 100 may change, the position of the terminal block 320 will also change accordingly. Therefore, the staff needs to choose whether the wire clamp 330 cooperates with the longitudinal screw hole 132 or the transverse screw hole 133 according to the actual situation.
[0041] like Figure 6 As shown, the lamp 200 includes: a lampshade 210, a light source board 220, a control component 230 and a light output component 240. The lampshade 210 is threadedly connected to the open port 120, the light source board 220 and the control component 230 are accommodated in the lampshade 210, the light source board 220 is electrically connected to the control component 230, the control component 230 is electrically connected to the wiring terminal 320, and the light output component 240 is covered on the light source board 220.
[0042] In combination with the above structure, the assembly process of the explosion-proof platform lamp 10 is described below. Figure 2 , Figure 4 and Figure 5 As shown:
[0043] When an inclined irradiation angle is required, during the assembly process of the explosion-proof platform lamp 10, the support port 130 is connected to the connecting pipe 400 of the bent pipe style structure, and then the connecting pipe 400 is mounted on the external lamp pole (the lamp pole is assumed to be in a vertical state in this case). If the irradiation is tilted downward, the staff connects the lamp 200 to the open port 120 tilted downward of the three-way base 100, and the corresponding terminal cover 140 is connected to another open port 120, so that a closed space is formed in the accommodating cavity 110, so that the lamp 200 will irradiate the oblique downward after power is turned on. During this period, the lead wire 310 enters the connecting pipe 400 from the lamp pole, and then passes through the support port 130 into the accommodating cavity 110. At this time, the wire clamp 330 cooperates with the longitudinal screw hole 132 to clamp the lead wire 310, and the lead wire 310 is connected to the terminal 320, and the terminal 320 is then connected to the control component 230 inside the lamp 200. In this way, the connection terminal 320 is located near the connection terminal cover 140. When maintenance is required, the staff only needs to open the connection terminal cover 140 to directly perform maintenance operations on the connection terminal 320. Similarly, if the light is irradiated upward, the staff only needs to swap the position of the lamp 200 and the connection terminal cover 140 so that the lamp 200 is connected to the open port 120 of the three-way base 100 that is tilted upward;
[0044] When a vertical irradiation angle is required, the support port 130 is connected to the connecting pipe 400 of the straight tube style structure, and then the connecting pipe 400 is sleeved on the external hanging pipe (the lamp pole installed on the ceiling). Then, the staff installs the lamp 200 at the open port 120 below the three-way base 100, and correspondingly, the terminal cover 140 is installed at another open port 120 located on the side of the three-way base 100. In this way, a closed space is formed in the accommodating cavity 110, and the lamp 200 will irradiate downward after power is turned on. During this period, the wire clamp 330 cooperates with the horizontal screw hole 133, and the terminal 320 is located near the terminal cover 140, which can facilitate the staff to carry out maintenance. Similarly, if horizontal irradiation is required, the staff only needs to swap the position of the lamp 200 and the terminal cover 140 so that the lamp 200 is connected to the open port 120 on the side of the three-way base 100.
[0045] Compared with the prior art, the explosion-proof platform lamp 10 of the present invention realizes the illumination angle adjustment by changing the style of the connecting pipe 400 and the connection relationship between the lamp 200 and the three-way base 100. In this way, there is no need to set an excessively long lead wire 310 to cope with the situation of being pulled during the traditional angle adjustment. At the same time, the traditional angle adjustment mode usually requires the lead wire 310 to be exposed to the outside, which is to prevent the lead wire 310 from being displaced and entangled with other lines after the angle adjustment, or even causing a short circuit. In the present invention, the lead wire 310 is accommodated in the accommodating cavity 110, avoiding the lead wire 310 from being exposed to the outside, protecting the lead wire 310 from aging and damage caused by wind and sun, thereby preventing spark accidents, strangulation accidents or electric shock accidents. And in the accommodating cavity 110, the lead wire 310 is fixed by the wire clamp 330 and the guide extension block 131, thereby avoiding the lead wire 310 from being entangled with other lines and even causing a short circuit.
[0046] Furthermore, according to different actual needs, the lamp 200 of the present invention can be equipped with a floodlight mode and an omnidirectional mode. The main difference between the two is the different structure of the light emitting component 240. In the floodlight mode, Figure 6 As shown, the light emitting assembly 240 includes a reflective cup 241 and a transparent lens 242. The reflective cup 241 is mounted on the light source board 220, and the transparent lens 242 is covered on the reflective cup 241 through a frame 243. In this way, when lighting, the light emitted by the light source board 220 will pass through the reflective cup 241 and the transparent lens 242 and radiate outward. The radiation range angle is small, and the brightness within the lighting range is high. In the omnidirectional mode, such as Figure 7 As shown, the light emitting assembly 240 includes an anti-glare cover 244 and a transparent cover 245. The anti-glare cover 244 is attached to the inner wall of the transparent cover 245. The transparent cover 245 is installed on the lampshade 210 through an outer frame 246 and covers the light source board 220. In contrast, the transparent cover 245 presents a convex hemispherical structure, so that when lighting, the light emitted by the light source board 220 will pass through the anti-glare cover 244 and the transparent cover 245 and radiate outward, and its lighting range is wider.
[0047] In the present invention, in order to achieve good heat dissipation of the lamp 200, a plurality of heat dissipation fins 211 (such as Figure 4 and Figure 8 The heat dissipation fins 211 are arranged in a circular array around the central axis of the lampshade 210. The heat dissipation fins 211 increase the surface area and effective heat dissipation area of the lampshade 210, thereby improving the heat dissipation efficiency. The terminal cover 140 is provided with a plurality of paddles 141 (as shown in FIG. Figure 8 As shown), the paddle 141 is provided to facilitate the staff to apply force when rotating.
[0048] In order to prevent the lampshade 210 and the terminal cover 140 from loosening during long-term use, a stop block 150 is also provided on the three-way base 100. Figure 3 and Figure 8 As shown, the stop block 150 is installed on the outer wall of the three-way base 100, and the two ends of the stop block 150 form a limit fork 151, and the limit forks 151 at the two ends respectively clamp the heat dissipation fins 211 and the paddle 141. Moreover, since the lampshade 210 and the terminal cover 140 are not in the same direction, under the linkage of the stop block 150, the lampshade 210 and the terminal cover 140 are clamped to each other, so that the lampshade 210 and the terminal cover 140 cannot rotate relative to the three-way base 100, that is, the connection between the lampshade 210 and the terminal cover 140 is prevented from being loose.
[0049] In the actual use of the lamp, it is found that when the lamp 200 needs to be repaired or replaced, the staff needs to remove the lampshade 210 and the terminal cover 140 first, and the anti-rotation block 150 is a small-sized component and is very easy to be lost. In addition, after the repair is completed, the staff needs to install the anti-rotation block 150 again, which makes the whole work complicated and the repair work efficiency is low.
[0050] like Fig.10 and Fig.11 As shown, in order to solve this technical problem, the present invention further improves the anti-rotation block 150. The anti-rotation block 150 is rotatably mounted on the outer wall of the three-way base 100 through a pin 160. The pin 160 has a boss 161, and a return spring 170 abuts against the boss 161 to apply elastic restoring force to the pin 160.
[0051] Next, the working principle of the improved anti-rotation block 150 is described:
[0052] When maintenance is required, the staff first pulls out the pin 160 together with the stop block 150 by hand, and then rotates the stop block 150 by an angle so that the limit fork 151 no longer holds the heat sink fin 211 and the paddle 141 to form a misalignment (such as Fig.11 shown);
[0053] The staff releases the pin 160 and the anti-rotation block 150. Under the elastic force of the reset spring 170, the pin 160 pulls the anti-rotation block 150 to reset. Since the limiting fork 151 no longer holds the heat dissipation fin 211 and the paddle 141, a misalignment is formed, so that the limiting fork 151 can no longer limit the heat dissipation fin 211 and the paddle 141, which is conducive to the rotation of the terminal cover 140.
[0054] The staff rotates the terminal cover 140. Since the limiting fork 151 can no longer limit the heat sink fin 211 and the paddle 141, the limiting fork 151 will adaptively rotate back and forth at a small angle during the rotation of the terminal cover 140, thereby facilitating the staff to remove the terminal cover 140 for maintenance.
[0055] When the inspection is completed, the staff pulls out the pin 160 and the stop block 150 together and rotates them in the opposite direction by an angle, and again makes the limit fork 151 no longer clamp the heat sink fin 211 and the paddle 141 to form a misalignment, so that the staff can smoothly rotate the terminal cover 140 in the opposite direction, thereby closing the terminal cover 140 tightly;
[0056] After the terminal cover 140 is closed tightly, the staff pulls out the pin 160 and the stop block 150 together. At this time, the limit fork 151 needs to be aligned with the heat sink fins 211 and the paddle 141. Under the elastic force of the reset spring 170, the limit fork 151 is clamped on the heat sink fins 211 and the paddle 141 to be limited and locked again.
[0057] From the above, it can be seen that by further improving the structure of the anti-rotation block 150, the terminal cover 140 can be removed and re-tightened without removing the anti-rotation block 150. On the one hand, it ensures that the small-sized component of the anti-rotation block 150 is not easily lost, and on the other hand, the efficiency of maintenance is improved.
[0058] In this embodiment, if Fig. 9 As shown, a packing groove 134 is provided on the support port 130, and the lead wire 310 passes through the packing groove 134. The bottom of the packing groove 134 is filled with a plugging material to fill the gap between the lead wire 310 and the support port 130. The plugging material can be selected from the existing caulking agent, foaming agent, gypsum or sealing glue according to actual needs. A compression screw block 135 connected to the inner wall thread is provided at the opening of the packing groove 134, and a flat washer is provided between the compression screw block 135 and the plugging material. The flat washer plays an isolating role to prevent the plugging material from directly contacting the compression screw block 135, causing the thread to stick, making subsequent disassembly difficult.
[0059] Preferably, a fixing seat 410 (such as Figure 3 As shown in FIG. 1 , the fixing seat 410 is installed on the supporting port 130 by means of bolts. The bolt connection prevents relative rotation between the connecting pipe 400 and the supporting port 130, thereby ensuring that the illumination angle of the lamp 200 does not change after installation.
[0060] In summary, the explosion-proof platform lamp 10 of the present invention can effectively seal the lead wire 310 of the lamp 200 on the basis of satisfying the angle adjustment function, thereby preventing spark accidents, strangulation accidents or electric shock accidents caused by aging and damage of the lead wire 310.
[0061] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
