Abstract
Description
Technical Field
[0001] This invention relates to the field of lighting equipment technology, and in particular to a high-lumen courtyard light for emergency repairs at construction sites. Background Technology
[0002] High-lumen courtyard lights are high-brightness emergency lighting devices suitable for engineering repair scenarios. They have the advantages of high illuminance, wide illumination range, and portable deployment. They are widely used in temporary lighting scenarios such as building construction, equipment maintenance, and outdoor fault repair, and are the core auxiliary equipment for emergency repair operations on construction sites.
[0003] Currently, most existing high-lumen courtyard lights used for emergency repairs have fixed, integrated support bases that lack self-adjusting leveling capabilities, resulting in extremely poor adaptability. Emergency repair work environments are complex and harsh, with surfaces often consisting of gravel, muddy soft soil, potholes, or temporary steel plates. The unevenness and stability of the ground are extremely poor. After the lights are installed and put into use, the base is prone to unilateral ground subsidence and localized sinking, leading to an imbalance in the support structure. The support will spontaneously tilt towards the side suspended above the ground. This tilting not only causes beam deviation, blind spots, and poor lighting uniformity, severely interfering with the precise operation of repair personnel and reducing work efficiency, but also allows external forces such as vibration and accidental impacts during operation to cause the entire light fixture to tip over. Since high-lumen courtyard lights lack protective structures, the light body, light source, and internal electrical structure are directly subjected to impacts after tipping, making them highly susceptible to damage, short circuits, and even complete failure. Summary of the Invention
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0013] As a preferred embodiment of the high-lumen courtyard light for emergency repair at the construction site described in this invention, the buffer unit further includes a limiting post, a movable groove is provided on the positioning shaft, the limiting post is located in the movable groove, a second spring is fixed between one end of the limiting post and the inner wall of the movable groove, a limiting hole is provided in the rotating sleeve, a push plate is provided in the limiting hole, and one end extends to the outside of the rotating sleeve.
[0014] As a preferred embodiment of the high-lumen courtyard light for emergency repair at construction sites described in this invention, the buffer unit further includes a turntable disposed within a support column, a cavity being formed within the support column, the turntable being rotatably connected within the cavity, an insertion rod being disposed on the top of the turntable, with one end penetrating into a groove and engaging with an insertion hole on one side of the rotating sleeve, a guide groove being formed on the turntable, and a guide shaft being fixed to one end of the insertion rod and movably connected to the guide groove.

[0017] The beneficial effects of this invention are as follows: when the lamps tilt due to ground settlement or external interference, the lamps can be automatically leveled and corrected, always maintaining the lamps in a vertical working state. This effectively avoids problems such as beam offset, blind spots, and uneven lighting caused by bracket tilt, ensuring stable lighting on the emergency repair work surface and greatly improving the accuracy and efficiency of on-site emergency repair operations.
[0018] Meanwhile, when the lamp is subjected to sudden external force and tends to tip over or actually tip over, the buffer unit can effectively buffer and deflect the impact force on the lamp body, preventing the lamp body, light source and internal electrical structure from being directly subjected to hard impact, greatly reducing the probability of lamp damage, short circuit and scrap, and reducing equipment operation and maintenance and replacement costs.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0032] Example 1, referring to Figures 1-4This is the first embodiment of the present invention. This embodiment provides a high-lumen courtyard light for emergency repairs at construction sites. The high-lumen courtyard light for emergency repairs at construction sites includes a base 1 and a support sleeve 2 fixed to the top of the base 1. A support column 3 is inserted into the support sleeve 2 and a lamp 4 is provided on the top. The support column 3 can move up and down within the support sleeve 2. A locking mechanism is provided on the support sleeve 2 to lock the adjusted support column 3. The lamp 4 can be tilted and adjusted at the top of the support column 3.
[0033] The positioning sleeve 5 is hinged to the bottom of the base 1 via a hinge seat. The support leg 6 is inserted into the positioning sleeve 5. There are multiple positioning sleeves 5 and support legs 6, which are evenly distributed in a ring at the bottom of the base 1. The two work together to support the base 1 and make the base 1 stable. When the base 1 tilts due to the settlement of one side of the ground, the support leg 6 on the side of the ground that has not settled will move into the positioning sleeve 5, causing that side of the base 1 to also sink and adjust the base 1 to a horizontal state. This allows the base 1 to remain horizontal even after the ground settles, avoiding problems such as beam deviation, blind spots on the working surface, and poor uniformity of lighting caused by the tilt of the base 1.
[0034] The rotating unit 7 is located inside the base 1 and connected to the support leg 6. It is used to drive the support leg 6 to move within the positioning sleeve 5. The number of rotating units 7 corresponds to the number of support legs 6. The trigger unit 8 is located inside the base 1 and is connected to the rotating unit 7 in a transmission manner. The number of trigger units 8 corresponds to the number of rotating units 7. The trigger unit 8 is used to sense the tilt of the base 1 and promptly drive the support leg 6 to move through the rotating unit 7.
[0035] Multiple buffer units 9 are arranged in a ring outside the support column 3. When the lamp 4 is tilted, the buffer units 9 can effectively buffer and deflect the impact force between the lamp 4 and the ground, avoiding direct hard impact on the lamp body, light source and internal electrical structure, greatly reducing the probability of lamp damage, short circuit and scrap, and reducing equipment operation and maintenance and replacement costs.
[0036] Example 2, refer to Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0037] Specifically, the rotating unit 7 includes a rotating column 71 disposed inside the positioning sleeve 5, with one end inserted into the support leg 6. The rotating column 71 has a first spiral groove 72. The fixed shaft 73 is fixed inside the support leg 6 and is movably connected to the first spiral groove 72. When the rotating column 71 rotates, the fixed shaft 73 will slide in the first spiral groove 72. Through the cooperation of the two, the support leg 6 can be driven to move into the positioning sleeve 5.
[0038] The outer side of the support leg 6 has a groove (not shown in the figure), and the positioning sleeve 5 has a slider (not shown in the figure) fixed inside. The slider is movably connected to the groove, and the two work together to limit the support leg 6 and prevent the support leg 6 from rotating.
[0039] The rotating unit 7 also includes a connecting column 74 connected to the end of the rotating column 71 via a universal joint. With the universal joint, the connecting column 74 can rotate with the positioning sleeve 5, and the rotating column 71 can also drive the connecting column 74 to rotate. The rotating column 75 is sleeved on the top of the connecting column 74, and the top end extends to the outside of the base 1. The connection part between the rotating column 75 and the connecting column 74 is rectangular, which allows the rotating column 75 to drive the connecting column 74 to rotate. The mainspring box 76 is fixed to the inner top wall of the base 1 via a telescopic rod. The telescopic rod is used to support and position the mainspring box 76. The mainspring 77 is set inside the mainspring box 76, and the inner ring of the mainspring 77 is fixed to the rotating column 75.
[0040] After the base 1 is placed in the designated position, pull the rotating column 75 upward and separate the bottom of the rotating column 75 from the connecting column 74. At this time, rotate the rotating column 75 and tighten the spring 77 to charge it. Then, move the rotating column 75 down and put it on the outside of the connecting column 74. When the rotating column 75 is released from its restriction and the spring 77 releases its torsional force, it can drive the rotating column 75 and the connecting column 74 to rotate, so that the connecting column 74 drives the rotating column 71 to rotate.
[0041] The triggering unit 8 includes a rotating block 81 fixed on the outside of the rotating column 75. The outer ring of the rotating block 81 has multiple limiting grooves. The limiting block 82 is located on one side of the rotating block 81 and engages with the limiting groove. The two work together to lock the rotating column 75, preventing the spring 77 from rotating.
[0042] The fixing rod 83 is fixed to one side of the limiting block 82, the support frame 84 is fixed to the inner bottom wall of the base 1, and the first tension spring 85 is fixed to the support frame 84 and the fixing rod 83 respectively by two mounting blocks. The first tension spring 85 is currently in a tensioned state.
[0043] The triggering unit 8 also includes a connecting sleeve 86 sleeved on the outside of the fixed rod 83 and movably connected to the support frame 84. The force plate 87 is fixed to the end of the connecting sleeve 86. The positioning seat 88 is fixed to the inner bottom wall of the base 1. The inner side of the positioning seat 88 is recessed downward. The sensing ball 89 is located inside the positioning seat 88. The sensing ball 89 has a certain weight and is located at the center of the positioning seat 88 under its own weight. The force plate 87 is in contact with the sensing ball 89 and is blocked by the sensing ball 89 and cannot move.
[0044] When the base 1 tilts, the sensing ball 89 rolls in the tilting direction and separates from the force plate 87 tilted in the opposite direction. At this time, the force plate 87 loses its obstruction and pulls the fixing rod 83 and the limiting block 82 to move through the first tension spring 85 in that direction, so that the limiting block 82 separates from the limiting groove. This releases the restriction of the rotating column 75, allowing the spring 77 to release the torsional force and move the support leg 6 in that direction into the positioning sleeve 5, thereby completing the leveling of the base 1. After the base 1 is leveled, the sensing ball 89 will reset and push the moved force plate 87 and fixing rod 83 back to their original positions, so that the limiting block 82 engages with the limiting groove again.
[0045] A third spring is fixed to the end of the fixed rod 83. The other end of the third spring is fixed to the inner wall of the connecting sleeve 86. When the sensing ball 89 rolls in the tilted direction, it will apply a pushing force to the force plate 87 in that direction. At this time, the force plate 87 will drive the connecting sleeve 86 to move and apply a pushing force to the third spring. When the sensing ball 89 is reset, the third spring will push the connecting sleeve 86 and the force plate 87 to reset.
[0046] The force of the third spring is greater than that of the first tension spring 85. Only after the force plate 87 and the connecting sleeve 86 lose resistance can the first tension spring 85 pull the fixed rod 83 to move. When the force plate 87 and the connecting sleeve 86 are obstructed and cannot move, the tension of the first tension spring 85 cannot offset the force of the third spring, so the fixed rod 83 will not move.
[0047] Example 3, referring to Figures 6-9 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0048] Specifically, the buffer unit 9 includes a rotating sleeve 91, a groove on the support column 3, a positioning shaft 92 fixed in the groove, the end of the rotating sleeve 91 rotatably connected to the outside of the positioning shaft 92, a support rod 93 inserted into the rotating sleeve 91, a first spring 94 fixed between the end of the support rod 93 and the inner wall of the rotating sleeve 91, the first spring 94 is in a compressed state and applies a push to the support rod 93, the bottom end of the support rod 93 contacts the inner wall of the groove and cannot move, and a torsion spring 96 is sleeved on the outside of the positioning shaft 92, with both ends fixed to the positioning shaft 92 and the rotating sleeve 91 respectively, and the torsion spring 96 is in a tightened state.
[0049] When the lamp 4 tilts, the rotating sleeve 91 will be unlocked, the torsion spring 96 will release its elasticity and drive the rotating sleeve 91 to rotate outward. At this time, the support rod 93 will separate from the inner wall of the groove and move outward by the pushing force of the first spring 94. When the lamp 4 is about to contact the ground, the support rod 93 will contact the ground first, and the impact force will be effectively buffered and deflected by the cooperation of the first spring 94, thereby avoiding the lamp 4 from directly hitting the ground. The impact force generated will cause the lamp to be damaged, short-circuited, or scrapped.
[0050] The buffer unit 9 also includes a limiting post 97. A movable groove is provided on the positioning shaft 92. The limiting post 97 is located in the movable groove. A second spring 98 is fixed between one end of the limiting post 97 and the inner wall of the movable groove. The second spring 98 is in a compressed state. A limiting hole 99 is provided in the rotating sleeve 91. A push plate 910 is provided in the limiting hole 99, and one end extends to the outside of the rotating sleeve 91.
[0051] When the rotating sleeve 91 rotates outward to a horizontal position, the limiting hole 99 will coincide with the limiting post 97. At this time, the second spring 98 will push the limiting post 97 into the limiting hole 99. The two work together to lock the angle of the rotating sleeve 91, preventing the rotating sleeve 91 from rotating due to impact force, which would cause the lamp 4 to directly contact the ground.
[0052] The rotating sleeve 91 has a moving groove for the push plate 910 to move. The moving groove is connected to the limiting hole 99. The push plate 910 is T-shaped and is locked in the moving groove and the limiting hole 99. When it is necessary to release the lock on the rotating sleeve 91, the push plate 910 is pushed to drive the limiting post 97 to separate from the limiting hole 99.
[0053] The buffer unit 9 also includes a turntable 911 disposed inside the support column 3. The support column 3 has a cavity, and the turntable 911 is rotatably connected inside the cavity. A socket is provided on one side of the rotating sleeve 91, and a plug rod 912 is disposed on the top of the turntable 911, with one end penetrating into the groove and engaging with the socket on one side of the rotating sleeve 91. The two work together to lock the rotating sleeve 91, preventing the rotating sleeve 91 from rotating outward when the lamp 4 is not tilted.
[0054] The turntable 911 has a guide groove 913, which is arc-shaped. The guide shaft 914 is fixed to one end of the insertion rod 912 and is movably connected to the guide groove 913. When the turntable 911 rotates, the guide shaft 914 will move along the guide groove 913 and drive the insertion rod 912 to separate from the insertion hole, thereby releasing the lock on the rotating sleeve 91.
[0055] The buffer unit 9 also includes a rotating rod 915 fixed to the bottom of the turntable 911, and a rotating sleeve 916 sleeved on the outside of the rotating rod 915 and rotatably connected to the support sleeve 2 through a connecting frame. The connection end between the rotating rod 915 and the rotating sleeve 916 is rectangular, which allows the rotating rod 915 to move up and down inside the rotating sleeve 916, and the rotating sleeve 916 can also drive the rotating rod 915 to rotate.
[0056] The movable column 917 is inserted into the bottom of the rotating sleeve 916, and its bottom end extends into the base 1. A force-bearing block 918 is fixed thereon. The bottom of the force-bearing block 918 contacts the sensing ball 89. A second spiral groove 919 is provided on the movable column 917. The connecting shaft 920 is fixed on the rotating sleeve 916 and is movably connected to the second spiral groove 919.
[0057] The buffer unit 9 also includes a positioning plate 921 fixed to the outside of the moving column 917, a positioning column 922 fixed to the inner bottom wall of the base 1, and a second tension spring 923 sleeved on the outside of the positioning column 922, with both ends fixed to the positioning plate 921 and the inner bottom wall of the base 1 respectively, and the second tension spring 923 is in a tensioned state.
[0058] When the base 1 tilts at a small angle due to ground subsidence, causing the sensing ball 89 to move, the movement of the sensing ball 89 will always remain below the force block 918, without separating from the force block 918, and will continuously block and limit the force block 918.
[0059] When the lamp 4 is knocked over by an external force, the base 1 will tilt at a large angle, which will increase the travel distance of the induction ball 89 and cause it to move out of the bottom of the force block 918. At this time, the second tension spring 923 will apply a downward pulling force to the positioning plate 921 and the moving column 917. When the moving column 917 moves downward, it will cause the connecting shaft 920 to slide in the second spiral groove 919. Through the cooperation of the two, the rotating sleeve 916 will be rotated, which will cause the rotating sleeve 916 to drive the rotating rod 915 and the turntable 911 to rotate.
[0060] An extension rod is fixed to one side of the positioning plate 921 and extends to the outside of the support sleeve 2. The positioning plate 921 and the moving column 917 can be pushed upward and reset through the extension rod.
[0061] In use, after the base 1 is placed in the designated position, pull the rotating column 75 upward to separate the bottom of the rotating column 75 from the connecting column 74. Then rotate the rotating column 75 and tighten the spring 77 to charge it. Then move the rotating column 75 downward and fit it on the outside of the connecting column 74. When the base 1 tilts, the sensing ball 89 will roll in the tilting direction and separate from the force plate 87 in the opposite tilting direction. At this time, the force plate 87 will lose its obstruction, and the first tension spring 85 in that direction will pull the fixing rod 83 and the limiting block 82 to move, so that the limiting block 82 separates from the limiting groove, thereby releasing the limitation of the rotating column 75. The mechanism allows the spring 77 to release torsional force, causing the rotating column 75 and the rotating column 71 to rotate. When the rotating column 71 rotates, it causes the fixed shaft 73 to slide in the first spiral groove 72. Through the cooperation of the two, the support leg 6 can be driven to move into the positioning sleeve 5. At this time, the support leg 6 on the side where the ground has not settled will move into the positioning sleeve 5, causing one side of the base 1 at that position to also sink and adjust the base 1 to a horizontal state. This allows the base 1 to remain horizontal even after the ground settles, avoiding problems such as beam deviation, blind spots on the working surface, and poor uniformity of illumination caused by the tilt of the base 1.
[0062] When the lamp 4 is knocked over by an external force, the base 1 will tilt at a large angle, which will increase the travel distance of the induction ball 89 and cause it to move out of the bottom of the force block 918. At this time, the second tension spring 923 will apply a downward pulling force to the positioning plate 921 and the moving column 917. When the moving column 917 moves downward, it will cause the connecting shaft 920 to slide in the second spiral groove 919. Through the cooperation of the two, the rotating sleeve 916 will rotate, which will cause the rotating rod 915 and the turntable 911 to rotate. When the turntable 911 rotates, it will cause the guide shaft 914 to move along the guide groove 913 and cause the insertion rod 912 to separate from the insertion hole, thereby releasing the lock on the rotating sleeve 91.
[0063] At this time, the torsion spring 96 will release its elastic force and drive the rotating sleeve 91 to rotate outward. At this time, the support rod 93 will separate from the inner wall of the groove and move outward by the pushing force of the first spring 94. When the lamp 4 is about to contact the ground, the support rod 93 will contact the ground first, and the impact force will be effectively buffered and unloaded by the cooperation of the first spring 94, thereby avoiding the lamp 4 from directly hitting the ground. The impact force generated will cause the lamp to be damaged, short-circuited, or scrapped.
[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
