[0007] Further, the lamp post further comprises a telescopic lamp rod, the lamp post is provided with a mounting hole extending along the central axis, the upper end and the lower end of the lamp post are provided with an upper cover and a lower cover respectively, the lamp rod is vertically arranged in the mounting hole and the upper end and the lower end of the lamp rod are connected with the upper cover and the lower cover respectively, the upper end of the lamp rod penetrates through the upper cover, and the lamp head is connected to the upper end of the lamp rod through a damping rotation structure.

[0008] Further, the lamp post further comprises a telescopic lamp rod, the lamp post is provided with a mounting hole extending along the central axis, the upper end and the lower end of the lamp post are provided with an upper cover and a lower cover respectively, the lamp rod is vertically arranged in the mounting hole and the upper end and the lower end of the lamp rod are connected with the upper cover and the lower cover respectively, the upper end of the lamp rod penetrates through the upper cover, and the lamp head is connected to the upper end of the lamp rod through a damping rotation structure.

[0009] Further, the upper cover is disc-shaped and has a vertically extending connecting cylinder at the center, the upper end of the lamp rod penetrates through the connecting cylinder, and the lamp rod is locked with the connecting cylinder through a clamp with a lock. In this way, the lamp rod can be stably locked on the upper cover through the clamp, and the lamp rod can be telescoped up and down by unlocking the clamp.

[0010] Further, the lamp rod comprises a telescopic pipe and a spring wire vertically arranged in the telescopic pipe, the damping rotation structure comprises a rotating member, the bottom of the rotating member is provided with a cylindrical upper positioning seat, the upper positioning seat is vertically arranged and the top is closed, the upper end of the spring wire is fixed on the inner top surface of the upper positioning seat, and the upper pipe opening of the telescopic pipe is connected to the bottom opening edge of the upper positioning seat. On the one hand, the lamp rod can be stably installed, and on the other hand, the telescoping function of the lamp rod can be effectively realized.

[0011] Furthermore, a lower positioning ring is fitted over the clamp at the upper end of the telescopic tube. A handle sleeve fitted over the telescopic tube is positioned between the lower positioning ring and the upper positioning seat. The tube also includes a lamp holder, which includes a receiving plate for detachably mounting the lamp holder and a connecting ring located directly below the receiving plate. The receiving plate has an open bottom, and the connecting ring is connected to the top surface of the upper cover. The receiving plate and the connecting ring are connected by connecting arms spaced evenly along the circumference, forming an operating gap between adjacent connecting arms that allows a hand to enter. The lamp pole passes through the lamp holder, and with the lamp holder mounted in the receiving plate, the clamp and handle sleeve are exposed in the operating gap. The handle sleeve facilitates user gripping of the lamp pole, the lamp holder ensures stable lamp holder placement, and the operating gap facilitates user operation of the clamp and lamp pole.

[0012] Furthermore, the two wheels are positioned on the left and right sides of the front end of the base, while the brake assembly is located between the two wheels. The bottom surface of the rear end of the base extends downwards to form a support block. In a horizontal position, the bottom surface of the support block is flush with the lowest point of each wheel. A grip is provided at the upper end of the lamp post, located on the same side as each wheel. This design allows for stable placement of the lamp post when the wheels are braked. When the lamp post needs to be moved, simply operate the brake assembly, grip the handle to tilt the lamp post to one side, lift the support block off the ground, and allow the wheels to roll, thus enabling the lamp post to move horizontally.

[0013] Furthermore, the lamp holder includes a base and an upper shell covering the base. The brake assembly includes a pedal and a pin. The front end of the upper shell is recessed inward to form a notch for rotatably mounting the pedal. First mounting protrusions corresponding to the wheels are formed on the left and right sides of the notch, and each wheel is rotatably mounted on the outside of its corresponding first mounting protrusion. Two pins are respectively located at the left and right ends of the pedal. Slides inclined inward from bottom to top are respectively provided at the left and right ends of the pedal's bottom. Each first mounting protrusion has a first shaft extending in the left-right direction. Each pin passes through a corresponding first shaft hole, with its outer end serving as a stop that abuts against the hub of the corresponding wheel, and its inner end serving as a sliding part. During pedal rotation, each sliding part slides back and forth along its corresponding slide rail. Each slide rail has a first limiting part and a second limiting part that restricts the sliding part of the corresponding pin. When the sliding part is at the first limiting part, the stop abuts against the hub of the corresponding wheel; when the sliding part is at the second limiting part, the stop disengages from the hub. Thus, by pressing the pedal, the stops abut against the hubs of the corresponding wheels, locking each wheel. With the wheels locked, pressing the pedal again disengages the stops from the hubs, unlocking each wheel.

[0014] Furthermore, each of the aforementioned pins has a circumferentially protruding limiting ring formed on its outer end, and the outer end of the channel of the first shaft hole is provided with a limiting ring step. A return spring is fitted onto the outer end of each pin, and each return spring is respectively limited between the corresponding limiting ring and the limiting ring step. Each return spring causes the corresponding pin to have its sliding portion slide upwards into the corresponding second limiting portion, while the stopping portion abuts against the hub of the corresponding wheel. Thus, in the unlocked state of each wheel, pressing the pedal allows each pin to return to the locked wheel state under the action of the corresponding return spring, facilitating the locking of each wheel.

[0015] Furthermore, to facilitate the installation of each slide, the left and right ends of the bottom of the pedal extend vertically downward to form extension walls. The middle part of each extension wall is recessed inward, and a mounting groove is formed on the outer side of each extension wall. A second mounting protrusion is formed on the inner side of each extension wall. Each slide is installed on the corresponding second mounting protrusion through the inner and outer sides. Each first limiting part extends vertically downward from the lower end of the corresponding slide, and each second limiting part extends vertically upward from the upper end of the corresponding slide. The size of each first limiting part and each second limiting part is matched with the size of the corresponding sliding part.

[0016] Compared with the prior art, the advantages of the present invention are as follows: The work post light of the present invention has a lamp post and a lamp head, wherein a first lighting source is provided on the lamp post, and a second lighting source is provided on the lamp head. The lamp post has a wide lighting angle (360°), and the lamp head can play a supplementary lighting role. Thus, the work post light of the present invention has the advantages of both wide lighting angle and sufficient lighting brightness, which meets the lighting needs of open work sites such as construction sites. Furthermore, the present invention facilitates the movement and control of the work post light by setting up wheels and brake components, solving the problem of inconvenient movement of work post lights in the prior art.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 13 As shown, a work post light includes a lamp holder 1, a lamp post 2, and a lamp head 3. The lamp post 2 is vertically mounted on the lamp holder 1, and the lamp head 3 is located at the top of the lamp post 2. A first lighting source 21 is arranged circumferentially on the lamp post 2, and a second lighting source 31 is arranged on the lamp head 3. The lamp holder 1 is provided with a wheel 4 that enables the lamp holder 1 to move horizontally and a brake assembly 5 for controlling the wheel 4. It can be seen that the work post light of the present invention has a lamp post 2 and a lamp head 3, wherein the lamp post 2 is provided with a first lighting source 21, and the lamp head 3 is provided with a second lighting source 31. The lamp post 2 has a wide illumination angle (360°), and the lamp head 3 can play a supplementary lighting role. Thus, the work post light of the present invention has the advantages of both a wide illumination angle and sufficient illumination brightness, meeting the lighting needs of open work sites such as construction sites. Furthermore, the present invention facilitates the movement and control of the work post light through the arrangement of the wheel 4 and the brake assembly 5, solving the problem of inconvenient movement of work post lights in the prior art.

[0032] Furthermore, the work post light of this invention also includes a vertically extendable lamp post 6. The lamp post 2 has a mounting hole 2410 extending along its central axis. An upper cover 22 and a lower cover 23 are respectively provided at the upper and lower ends of the lamp post 2. The lamp post 6 is vertically inserted through the mounting hole 2410, and its upper and lower ends are connected to the upper cover 22 and the lower cover 23 respectively. The upper end of the lamp post 6 passes through the upper cover 22, and the lamp head 3 is rotatably connected to the upper end of the lamp post 6 via a damping rotation structure 8. This allows for adjustment of the height and illumination angle of the lamp head 3 according to usage needs, facilitating user operation and providing supplementary lighting at a fixed height and angle. In this embodiment, the lamp head 3 is disc-shaped. In the initial state, the lamp head 3 is placed horizontally. The second lighting source 31 is a COB light source and is located at the center of the top surface of the lamp head 3. In addition, the damping rotation structure 8 is a conventional structure except for the rotating component 81 described below. The damping rotation structure 8 can realize the rotation of the lamp head 3 from the initial state to the vertical state (i.e., rotate it 90°).

[0033] Furthermore, the aforementioned lamp post 2 includes, from the inside to the outside along the axial direction, a mounting sleeve 24 and an outer sleeve 25. The upper and lower ends of the mounting sleeve 24 and the outer sleeve 25 are respectively connected to the bottom surface of the upper cover 22 and the top surface of the lower cover 23. The aforementioned mounting sleeve 24 includes a cylindrical inner tube 241 and an outer tube 242 with a regular polygonal cross-section (a regular hexagon in this embodiment). The aforementioned first lighting source 21 is a lamp strip, which consists of six lamp strips and corresponds one-to-one with the outer surface of the aforementioned outer tube 242. Each lamp strip is detachably mounted on the outer surface of the outer tube 242. Specifically, in this embodiment, each outer surface of the outer tube 242 is provided with a vertically extending snap-fit ​​groove 2421, and each lamp strip is installed in the corresponding snap-fit ​​groove 2421 by means of a snap fastener.

[0034] Furthermore, the inner cavity of the inner tube 241 forms the mounting channel 2410, and the outer tube 242 is sleeved outside the inner tube 241 with a circumferentially extending heat dissipation annular gap 240 between them. Vertically arranged and radially extending connecting spokes 243 are spaced circumferentially within this heat dissipation annular gap 240. One end of each connecting spoke 243 is fixed to the outer circumferential surface of the inner tube 241, and the other end is fixed to the inner circumferential surface of the outer tube 242. This ensures the stability of the internal structure of the lamp post 2 and facilitates the installation of the first lighting source 21 and the lamp post 6. In addition, it effectively meets the heat dissipation needs of each first lighting source 21, preventing excessively high operating temperatures.

[0035] In this embodiment, a first connecting groove 201 and a second connecting groove 202, matching the shapes of the ports of the mounting sleeve 24 and the outer sleeve 25, are respectively formed on the bottom surface of the upper cover 22 and the top surface of the lower cover 23. The upper and lower ports of the mounting sleeve 24 and the outer sleeve 25 are respectively inserted into the corresponding connecting grooves. Furthermore, the upper cover 22 is disc-shaped with a vertically extending connecting cylinder 221 at its center. The upper end of the lamp post 6 passes through the connecting cylinder 221, and the lamp post 6 is locked to the connecting cylinder 221 by a clamp 7 with a locking buckle 71. Thus, the clamp 7 securely locks the lamp post 6 to the upper cover 22, and unlocking the clamp 7 allows the lamp post 6 to extend and retract vertically.

[0036] In this embodiment, the lamp post 6 includes a telescopic tube 61 and a spring wire 62 vertically threaded through the telescopic tube 61. The damping rotation structure 8 includes a rotating member 81, the bottom of which is fitted with a cylindrical upper positioning seat 612. The upper positioning seat 612 is vertically positioned and closed at the top. The upper end of the spring wire 62 is fixed to the inner top surface of the upper positioning seat 612, and the upper opening of the telescopic tube 61 is fitted onto the bottom edge of the upper positioning seat 612. This design ensures both stable installation of the lamp post 6 and effective vertical telescopic movement of the lamp post 6. Furthermore, a lower positioning ring 611 is fitted above the clamp 7 at the upper end of the telescopic tube 61. A handle glove 613, which is sleeved on the outside of the telescopic tube 61, is provided between the lower positioning ring 611 and the upper positioning seat 612. The tube also includes a lamp holder 32, which includes a receiving plate 321 for detachably installing the lamp holder 3 and a connecting ring 322 located directly below the receiving plate 321. The bottom of the receiving plate 321 is open and the connecting ring 322 is connected to the top surface of the upper cover 22. The receiving plate 321 and the connecting ring 322 are connected by connecting arms 323 that are evenly spaced along the circumference. An operating gap 320 is formed between adjacent connecting arms 323, allowing a hand to be inserted. The lamp post 6 passes through the lamp holder 32 and the lamp holder 3 is installed in the receiving plate 321. The clamp 7 and the handle glove 613 are exposed in the operating gap 320. The glove 613 makes it easier for users to hold the lamp pole 6, the lamp head holder 32 ensures the lamp head 3 is placed stably, and the operating gap 320 makes it easier for users to operate the clamp 7 and the lamp pole 6.

[0037] Furthermore, in this embodiment, there are two wheels 4, positioned on the left and right sides of the front end of the base 11. The brake assembly 5 is positioned between the two wheels 4. The bottom surface of the rear end of the base 11 extends downward to form a support block 10. In a horizontally placed state, the bottom surface of the support block 10 is flush with the lowest point of each wheel 4. The upper end of the lamp post 2 is provided with a handle 26 for gripping, which is located on the same side as each wheel 4. This allows the lamp post to be placed stably when the wheels 4 are braked. When the lamp post needs to be moved, simply operate the brake assembly 5, grip the handle to tilt the lamp post to one side, lift the support block 10 off the ground, and allow each wheel 4 to roll, thus enabling the lamp post to move horizontally. In this embodiment, the handle 26 is connected to the upper cover 22 via a collar 261.

[0038] Specifically, the lamp holder 1 includes a base 11 and an upper shell 12 covering the base 11. The brake assembly 5 includes a pedal 51 and a pin 52. The front end of the upper shell 12 is recessed inward to form a notch 121 for fitting the pedal 51. The left and right sides of the notch 121 respectively form first mounting protrusions 122 corresponding to the wheels 4. The left and right sides of the rear end of the pedal 51 are rotatably connected to the shaft holes on the corresponding first mounting protrusions 122 through left and right extending pivots 510. Each wheel 4 is rotatably mounted on the outer side of the corresponding first mounting protrusion 122 via axle 40. Two pins 52 are respectively located at the left and right ends of the pedal 51. The left and right ends of the bottom of the pedal 51 are respectively provided with inwardly inclined slides 511 from bottom to top. Each first mounting protrusion 122 has a first axle hole 1221 and a second axle hole (not shown) extending in the left-right direction. The first axle hole 1221 and the second axle hole are arranged side-by-side. Each pin 52 passes through the corresponding first axle hole 1221, and each wheel axle 40 passes through the corresponding second axle hole. The outer end of each pin 52 can engage with the corresponding wheel. The stop portion 521 abuts against the hub 41 of wheel 4, and the inner ends are sliding portions 522. During the rotation of the pedal 51, each sliding portion 522 can slide back and forth along the corresponding slide rail 511. The two ends of each slide rail 511 are respectively a first limiting portion 5111 and a second limiting portion 5112 that can limit the sliding portion 522 of the corresponding pin 52. When each sliding portion 522 is located at the corresponding first limiting portion 5111, each stop portion 521 abuts against the hub 41 of the corresponding wheel 4. When each sliding portion 522 is located at the corresponding second limiting portion 5112, each stop portion 521 disengages from the hub 41 of the corresponding wheel 4. By stepping on the pedal 51, each stop 521 abuts against the hub 41 of its corresponding wheel 4, thus locking each wheel 4. With each wheel 4 locked, stepping on the pedal 51 again disengages each stop 521 from the hub 41, thus unlocking each wheel 4. In this embodiment, the outer surface of each stop 521 is smooth and can fit into the gap between adjacent spokes of the corresponding hub. Each sliding part 522 is spherical, and the size of each slide rail 511 matches the size of its corresponding sliding part 522.

[0039] Preferably, each of the aforementioned pins 52 has a circumferentially protruding limiting ring 523 formed on its outer end, and the outer end of the channel of the first shaft hole 1221 is provided with a limiting ring step 1222. A return spring 524 is sleeved on the outer end of each pin 52, and each return spring 524 is respectively limited between the corresponding limiting ring 523 and the limiting ring step 1222. Furthermore, each return spring 524 causes the corresponding pin 52 to have its sliding portion 522 slide upwards into the corresponding second limiting portion 5112, and the stopping portion 521 abuts against the hub of the corresponding wheel 4. Thus, when each wheel 4 is unlocked, by stepping on the pedal 51, each pin 52 can return to the locked wheel 4 state under the action of the corresponding return spring 524, facilitating the locking of each wheel 4. Furthermore, to facilitate the installation of each slide rail 511, the left and right ends of the bottom of the aforementioned pedal 51 extend vertically downwards to form extension walls 512. The middle part of each extension wall 511 is recessed inwards, and mounting grooves 5121 are formed on the outer side of each extension wall 512. Second mounting protrusions 5112 are formed on the inner side of each extension wall 512. Each slide rail 511 is disposed on the corresponding second mounting protrusion 5112 through the inner and outer sides. Each first limiting part 5111 extends vertically downwards from the lower end of the corresponding slide rail 511, and each second limiting part 5112 extends vertically upwards from the upper end of the corresponding slide rail 511. The size of each first limiting part 5111 and the second limiting part 5112 is matched with the size of the corresponding sliding part 522.

[0040] Furthermore, in this embodiment, a rechargeable battery 91 is installed in the internal space enclosed by the upper shell 12 and the base 11, and a power cord 92 is also included. A waterproof socket 93 and a winding spool 123 for winding the power cord 92 are respectively provided on the rear side of the upper shell 12. In addition, a first switch 94 for controlling the opening and closing and a second switch 95 for controlling the brightness are respectively provided on the right side of the upper shell 12.
