DETAILED DESCRIPTION

[0030] The embodiment of the present invention discloses a LED street lamp structure that is easy to disassemble and assemble. Through the arrangement of the fixed rod assembly 4, when the guide plug-in column 602 enters the lamp holder shell 3, the locking head 4011 at the end of the guide locking plate 401 will enter the locking groove 603, thereby fixing the guide plug-in column 602, so that the guide plug-in column 602 is fixed as soon as it is inserted. When disassembling, the tooth plate 406 is directly pressed to allow the guide locking plate 401 to flip over and leave the guide plug-in column 602, thereby achieving the effect of simple disassembly and assembly, and improving the disassembly and assembly efficiency of the street lamp.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] Example 1:

[0033] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The embodiment of the present invention discloses an LED street lamp structure that is easy to disassemble and assemble, including a fixed rod assembly 4, which is arranged inside and outside the lamp holder shell 3, and a lock cover assembly 5 is arranged outside the lamp holder shell 3. The fixed rod assembly 4 includes a guide lock connecting plate 401, and side terminal columns 402 are symmetrically fixed on both sides of the guide lock connecting plate 401. The other end of the side terminal column 402 is fixedly provided with a driving gear 405, and the outer side of the driving gear 405 is meshed with a pressure-driven tooth plate 406, and the outer side of the side terminal column 402 is rotatably provided with an external support plate 404. The external support plate 404 is fixedly provided on the outer side of the lamp holder shell 3, and four insertion openings are opened on the outer side of the lamp holder shell 3. The guide lock connecting plate 401 is inserted into the inner side of the insertion opening, and the middle section of the guide lock connecting plate 401 is inclined. A locking head 4011 is provided at the end of the guide lock connecting plate 401, and the pressure-driven tooth plate 406 is connected to the lock cover assembly 5 through a fixed ring block 409.

[0034] Insert the lamp holder shell 3 on the top of the guide plug column 602. Since the middle segment of the fixed rod assembly 4 is tilted, it will have a certain guiding effect on the inserted guide plug column 602, so that the locking head 4011 can enter the locking groove 603. When the guide plug column 602 contacts the middle segment of the guide locking plate 401, the guide locking plates 401 in the four fixed rod assemblies 4 will expand outward at the same time until the locking groove 603 corresponds to the locking head 4011. The locking head 4011 will enter the locking groove 603 and lock the guide plug column 602, thereby completing the installation of the fixed structure 1.

[0035] When removing the PMMA lampshade 2 or the lamp holder shell 3, directly press down the pressure-driven tooth plate 406 in the fixed rod assembly 4. At this time, the return spring 407 will be compressed, and the descent of the pressure-driven tooth plate 406 will cause the driving gear 405 to rotate. The rotation of the driving gear 405 will drive the side terminal column 402 to rotate, and then the guide lock plate 401 will rotate. The guide lock plate 401 will drive the locking head 4011 and the pressure pad 4012 away from the locking groove 603, and the reset torsion spring 403 will shrink. Then lift the lamp holder shell 3 upward to make the lamp holder shell 3 detach from the guide plug column 602.

[0036] See Figure 3Both ends of the street light crossbar 6 are provided with guide plug-in columns 602, which are inserted into the interior of the lamp holder shell 3. Four locking grooves 603 are opened on the outer side of one end of the guide plug-in column 602.

[0037] The locking groove 603 is provided to facilitate the locking head 4011 to be locked into the locking guide plug post 602, thereby allowing the street lamp to be installed.

[0038] Among them, the outer side of the pressure-driven tooth plate 406 is slidingly provided with a bottom support frame 408, and the bottom support frame 408 is fixedly provided at the bottom end of the external support plate 404. The top of the other side of the pressure-driven tooth plate 406 is fixedly provided with a rebound spring 407, and the rebound spring 407 is fixedly provided at the top of the bottom support frame 408. The outer side of the side end column 402 away from one end is fixedly provided with a return torsion spring 403, and the other end of the return torsion spring 403 is fixedly provided on one side of the external support plate 404. The fixed ring block 409 is fixedly provided at the top of the pressure-driven tooth plate 406, and an annular handle 410 is fixedly provided between the fixed ring blocks 409. The annular handle 410 is located on the inner side of the sliding groove opening opened on both sides of the protective cover shell 301.

[0039] The setting of the bottom bracket 408 facilitates the movement of the pressure-driven tooth plate 406 to be more stable. The rebound force of the rebound spring 407 can make the pressure-driven tooth plate 406 rise after being lowered. The return torsion spring 403 can make the side terminal column 402 return to its original position after rotation, and provide pressure for the guide locking plate 401 when the locking head 4011 fixes the guide plug-in column 602, so that the locking head 4011 is tighter when fixed. The opening of the slide groove facilitates the movement of the annular handle 410.

[0040] Note that, see Figure 6 A pressure pad 4012 is fixedly provided on one side of the locking head 4011. The pressure pad 4012 is made of rubber material. The pressure pad 4012 contacts the inner side of the locking groove 603. A first end seat 4013 is rotatably provided on one side of the middle segment close to the lamp holder shell 3. A second end seat 4016 is rotatably provided on the inner side of the lamp holder shell 3. A telescopic rod 4014 and a pressure storage spring 4015 are fixedly provided between the first end seat 4013 and the second end seat 4016.

[0041] When the telescopic rod 4014 and the pressure storage spring 4015 are in a compressed state, they can provide pressure for the middle segment, so that the locking head 4011 can press the pressure pad 4012, and the pressure pad 4012 is made of rubber material, which can produce deformation, thereby making the locking head 4011 more stable when fixing the guide plug column 602.

[0042] Reference Figure 5 、 Figure 7 and Figure 8The lock cover assembly 5 includes a receiving bracket 501, a reset member 502 is fixedly provided on the inner side of the top of the receiving bracket 501, and a locking tongue plate 503 is fixedly provided on the other end of the reset member 502, and the locking tongue plate 503 is rotatably provided on one side of the receiving bracket 501, and the reset member 502 is made of memory alloy material and is wavy in shape. A protective cover shell 301 is slidably provided on one side of the bottom end of the receiving bracket 501, and the protective cover shell 301 is covered on the outside of the fixed rod assembly 4. The protective cover shell 301 is fixedly provided on the outside of the lamp holder shell 3, and sliding grooves are provided on both sides of the protective cover shell 301 and on the side away from the lamp holder shell 3. The receiving bracket 501 is fixedly connected to the fixed ring block 409 through the connecting block bracket 504, and the connecting block bracket 504 is located on the inner side of the sliding groove.

[0043] After the PMMA lampshade 2 is installed, the locking tongue plate 503 in the lock cover assembly 5 will be located at the top of the cover shell pressure edge 201. Since the reset member 502 is made of memory alloy material, the reset member 502 will apply tension at the connection between it and the locking tongue plate 503, thereby causing the part where the locking tongue plate 503 contacts the cover shell pressure edge 201 to obtain downward pressure, thereby tightening the cover shell pressure edge 201 and enhancing the sealing between the PMMA lampshade 2 and the lamp holder shell 3.

[0044] When the fixed ring block 409 is pressed down, the connecting bracket 504 in the lock cover assembly 5 drives the receiving bracket 501 to descend, and the descent of the receiving bracket 501 drives the locking tongue plate 503 to move together. Since the locking tongue plate 503 abuts against the cover pressure edge 201, the end of the locking tongue plate 503 in contact with the cover pressure edge 201 will tilt upward, and as the receiving bracket 501 descends, the lower extended edge 3023 of the locking tongue plate 503 comes into contact. At this time, the state of the reset member 502 is stretched and lengthened, because the reset member 502 abuts against the locking tongue plate The connection of 503 is in an inclined downward state, at this time the PMMA lampshade 2 can be directly disassembled, and when the receiving bracket 501 rises, the locking tongue plate 503 will slide upward along the outer wall of the lower extended edge 3023 until the locking tongue plate 503 reaches the bayonet 3021, and the locking tongue plate 503 is restored to its state. When the locking tongue plate 503 does not press the cover edge 201, the connection between the locking tongue plate 503 and the reset member 502 is inclined upward, and the other end of the locking tongue plate 503 is inclined downward, which can provide downward pressure for the cover edge 201.

[0045] Example 2:

[0046] Reference Figure 9 and Figure 10The outer side of the top of the lamp holder shell 3 is provided with an outer edge 302, and the outer edge 302 includes an upper extended edge 3022 and a lower extended edge 3023. Four bayonet holes 3021 are opened on the outer side of the upper extended edge 3022, and the bayonet holes 3021 are provided corresponding to the locking tongue plate 503. The bottom end of the PMMA lampshade 2 is provided with a cover pressing edge 201, and the bottom end of the cover pressing edge 201 is fixedly provided with a waterproof silicone ring 202. The inner side of the lamp holder shell 3 is provided with an inner waterproof ring 3011.

[0047] Among them, the cover pressing edge 201 can be set to a spiral shape, and a buckle plate should be set on the inner side of the upper extended edge 3022, so that the cover pressing edge 201 can be spirally inserted into the inner side of the upper extended edge 3022, so as to increase the tightness of the PMMA lampshade 2 after installation. The setting of the lower extended edge 3023 is to facilitate the smoother movement of the locking tongue plate 503, and the setting of the bayonet 3021 is to facilitate the unlocking of the locking tongue plate 503 and slide along the outer side of the lower extended edge 3023.

[0048] An anti-rotation bayonet is provided on the outer side of the bottom end of the lamp holder shell 3, and a street light main pole 601 is fixedly provided in the middle of the street light crossbar 6. The street light main pole 601 is fixed to the ground. A diagonal brace 701 is detachably provided on the outer side of the lamp holder shell 3, and a decorative frame 7 is detachably provided on the top of the diagonal brace 701.

[0049] The anti-rotation bayonet is set to prevent the installation direction of the street light from being reversed.

[0050] Working Principle: Before installing the fixing structure 1, the PMMA lampshade 2 can be screwed into the top of the lamp holder shell 3. The locking bolt plate 503 in the lock cover assembly 5 will be located at the top of the cover shell pressure edge 201. Since the reset member 502 is made of memory alloy material, the reset member 502 will apply tension at the connection between it and the locking bolt plate 503, thereby applying downward pressure to the contact area between the locking bolt plate 503 and the cover shell pressure edge 201, thereby tightening the cover shell pressure edge 201 and enhancing the sealing between the PMMA lampshade 2 and the lamp holder shell 3.

[0051] Then, the lamp holder shell 3 is inserted on the top of the guide plug post 602. Since the middle section of the fixed rod assembly 4 is inclined, it will have a certain guiding effect on the inserted guide plug post 602, so that the locking head 4011 can enter the locking groove 603. The anti-rotation bayonet on the outer side of the bottom of the lamp holder shell 3 can prevent the lamp holder shell 3 from being installed in the reverse direction. When the guide plug post 602 contacts the middle section of the guide locking plate 401, the guide locking plates 401 in the four fixed rod assemblies 4 will expand outward at the same time until the locking groove 603 corresponds to the locking head 4011. The locking head 4011 will enter the locking groove 603 and lock the guide plug post 602, thereby completing the installation of the fixed structure 1.

[0052] Wherein, after the locking head 4011 enters the locking groove 603, the telescopic rod 4014 and the pressure storage spring 4015 are in compression state, so as to provide pressure for the middle section, so that the locking head 4011 can press the pressure pad 4012, and the pressure pad 4012 is made of rubber material, so that it can be deformed, so that the locking head 4011 is more stable when fixing the guide and plug-in column 602, and when not fixing the guide and plug-in column 602, the four locking heads 4011 are in a state of contraction and folding, that is, the four locking heads 4011 are slightly inclined towards the direction of approaching;

[0053] When disassembling the PMMA lampshade 2 or the lamp holder shell 3, directly press the pressure driving tooth plate 406 in the fixed rod assembly 4, at this time, the back-up spring 407 is compressed, and the descent of the pressure driving tooth plate 406 makes the driving gear 405 rotate, the rotation of the driving gear 405 drives the side joint end column 402 to rotate, thereby making the guide and lock connecting plate 401 rotate, the guide and lock connecting plate 401 drives the locking head 4011 and the pressure pad 4012 away from the locking groove 603, and the reset torsional spring 403 is retracted, then lifting the lamp holder shell 3 upwards can make the lamp holder shell 3 separate from the guide and plug-in column 602, and when pressing the pressure driving tooth plate 406, the operator can directly apply pressure to the annular handle 410, so that the pressure is transmitted to the pressure driving tooth plate 406 through the fixed ring block 409, which is convenient to operate, so that the street lamp can be quickly disassembled, thereby improving the disassembly efficiency of the street lamp;

[0054] It should be noted that when the fixed ring block 409 is pressed down, the connecting block support 504 in the lock cover assembly 5 drives the bearing support 501 to descend, the descent of the bearing support 501 drives the pressure lock tongue plate 503 to move together, because the pressure lock tongue plate 503 abuts against the cover shell pressing edge 201, therefore the end part of the pressure lock tongue plate 503 in contact with the cover shell pressing edge 201 will be inclined upward, and along with the descent of the bearing support 501, the pressure lock tongue plate 503 contacts the lower extension surrounding edge 3023, at this time, the state of the reset member 502 is stretched and lengthened, because the connection part of the reset member 502 and the pressure lock tongue plate 503 is in an inclined downward state, at this time, the PMMA lampshade 2 can be directly disassembled, when the bearing support 501 rises back, the pressure lock tongue plate 503 slides upward along the outer wall of the lower extension surrounding edge 3023, until the pressure lock tongue plate 503 reaches the bayonet 3021, the pressure lock tongue plate 503 recovers, when the pressure lock tongue plate 503 does not press the cover shell pressing edge 201, the connection part of the pressure lock tongue plate 503 and the reset member 502 is inclined upward, and the other end part of the pressure lock tongue plate 503 is inclined downward, so as to provide pressure to the cover shell pressing edge 201, thereby improving the sealing between the PMMA lampshade 2 and the lamp holder shell 3.

[0055] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.

[0056] The above is only a preferred specific implementation of the embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
