Description

Technical Field

[0001] This invention relates to the field of industrial lighting technology, and in particular to a lighting fixture with deployable support legs. Background Technology

[0002] Feedback from users of the previous generation of traditional lighting fixtures is as follows: 1. The support leg assembly located at the bottom of the control seat requires staff to bend down and manually operate it, whether to unfold or retract it, resulting in a poor user experience. 2. The support leg assembly mainly consists of two rotatable support legs. During the retraction process, one support leg must be retracted inwards first, followed by the other support leg retracted outwards. Only in this way can both support legs be neatly retracted into the receiving slot. If the retraction order is incorrect, the two support legs will not be neatly retracted into the receiving slot. However, in actual operation, workers do not actively distinguish the order of retraction; they will randomly rotate any support leg. When they find that the support leg cannot be neatly retracted, they will readjust the retraction order. As a result, this traditional structural design will bring workers an unpleasant operating experience, and the operation process is time-consuming and laborious.

[0003] Therefore, it is necessary to optimize the structure of traditional lighting fixtures to address the aforementioned issues raised by users. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lighting fixture with expandable support legs. On the one hand, it eliminates the need for workers to bend down and manually operate the support legs to expand or retract them. On the other hand, it can effectively guide workers during the retraction of the support legs, allowing them to quickly determine the correct retraction sequence and thus retract the support legs quickly.

[0005] The objective of this invention is achieved through the following technical solution: A lighting fixture with deployable support legs includes: a fixture body, a caster assembly, and a support leg assembly; The lamp body includes: a control base, a lifting push-pull rod, and a light-emitting element; the lifting push-pull rod is erected on the control base, the light-emitting element is disposed on the lifting push-pull rod, and the light-emitting element realizes lifting and lowering movement based on the lifting push-pull rod; The caster assembly and the support leg assembly are located at the bottom of the control base; The support leg assembly includes an active support leg and a passive support leg. The bottom of the control base is provided with a receiving groove. The active support leg and the passive support leg can be accommodated in the receiving groove and can be extended out of the receiving groove based on the split rotation.

[0006] In one embodiment, The support leg assembly also includes a transmission gear set and a trigger button; the connecting end of the active support leg is rotatably disposed in the receiving groove via a torsion spring, the torsion spring being used to provide elastic force to the active support leg so that the active support leg has a tendency to extend outward from the receiving groove; The connecting end of the driven support foot is rotatably disposed in the receiving groove, and the connecting end of the driven support foot and the connecting end of the active support foot form a mutual power transmission through the transmission gear set; The bottom of the control base is provided with a slot, and the free end of the active support leg is provided with a floating buckle that cooperates with the slot; When the active support foot and the driven support foot are received in the receiving groove, the active support foot is located at the opening of the receiving groove, and the driven support foot is located inside the receiving groove. The trigger button is used to cause the buckle to disengage from the slot. The elastic force of the torsion spring causes the connecting end of the active support foot to rotate, and the power transmission of the transmission gear set causes the connecting end of the driven support foot to rotate, thereby causing the active support foot and the driven support foot to unfold outside the receiving slot.

[0007] In one embodiment, the transmission gear set includes a plurality of sequentially meshing gear units, the number of which is an even number, one of which is located at the connection end of the active support foot, and another of which is located at the connection end of the driven support foot.

[0008] In one embodiment, the length of the driven support foot is less than the length of the active support foot.

[0009] In one embodiment, the trigger button includes a button body and a push rod drivenly connected to the button body. The push rod is movably received in the slot by a spring. The button body drives the push rod to overcome the elastic force of the spring, so that one end of the push rod extends out of the slot.

[0010] In one embodiment, an inclined guide surface is formed on the end face of the latch.

[0011] In one embodiment, the control base is provided with a control board and an energy storage battery. The control board is electrically connected to the light-emitting element, and the energy storage battery is used to provide power to the light-emitting element.

[0012] In one embodiment, the light source is a high-power LED lamp.

[0013] In one embodiment, the energy storage battery is a cylindrical lithium battery.

[0014] The present invention provides a lighting fixture with expandable support legs. On the one hand, it eliminates the need for staff to bend down and manually operate the support legs to expand or retract them. On the other hand, during the retraction of the support legs, it can effectively guide staff to quickly determine the correct retraction sequence, thereby enabling the support legs to be retracted quickly.

[0017] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Currently, the housings of lamps on the market only meet basic waterproof requirements. These products themselves can easily become ignition sources when operating in explosive environments, particularly lacking consideration for circuit power limiting, spark limiting, and limiting gas infiltration into the lamp body to a certain volume. Furthermore, oil and petrochemical sites with high explosion hazard levels have higher requirements for explosion-proof lamps, especially high-power mobile products with 80W batteries.

[0021] The lighting fixtures of this invention are suitable for mobile emergency rescue and relief operations in Zone 1 and Zone 21 environments in the petroleum and chemical industries where hazardous gases are present. They possess a high explosion-proof rating, and the separation of light and heat, as well as electrical heat, prevents the accumulation of heat and light, thus avoiding the generation of higher surface temperatures that could become ignition sources in explosive gas environments. To meet various emergency and rescue needs at night, high-power, high-illuminance, and wide-range lighting fixtures are required, necessitating the use of large-capacity batteries. High-power lamp holders and large-capacity batteries require control over explosion-proof parameters such as surface temperature and internal spark energy to prevent the product from becoming an ignition source in explosive hazardous environments.

[0022] like Figure 1 As shown, the present invention discloses a lighting fixture 10 with deployable support legs, including: a fixture body 20, a caster assembly 30, and a support leg assembly 40.

[0023] like Figure 1As shown, the lamp body 20 includes: a control base 21, a lifting push-pull rod 22, and a light-emitting element 23. The lifting push-pull rod 22 stands on the control base 21, and the light-emitting element 23 is disposed on the lifting push-pull rod 22. The light-emitting element 23 achieves lifting and lowering movement based on the lifting push-pull rod 22. In this invention, the lifting push-pull rod 22 is implemented using existing technology, such as a push-pull rod installed on a suitcase, where the extension or retraction of the push-pull rod is achieved by pressing a corresponding button. When the product rises or falls to a specified height, the lifting push-pull rod automatically locks itself. When adjustment is needed, pressing the switch restores the height adjustment, effectively solving the storage problem and the problem of adjusting the height during use, achieving the purpose of portability.

[0024] The light-emitting element 23 is mounted on the lifting push-pull rod 22. The height of the light-emitting element 23 can be adjusted by raising and lowering the lifting push-pull rod 22. In this embodiment, the light-emitting element 23 is a high-power LED lamp. The lamp head (light-emitting element 23) contains optical elements, including LEDs, lenses, and a metal heat sink for the lamp body.

[0025] In this embodiment, the control base 21 houses a control board and an energy storage battery. The control board is electrically connected to the light-emitting element 23, and the energy storage battery provides power to the light-emitting element 23. The energy storage battery is preferably a cylindrical lithium battery. The entire enclosure (control base 21) is a composite explosion-proof design, meaning all circuit components are housed within an increased safety enclosure. It comprises four combined explosion-proof methods: wiring increased safety, battery encapsulation (MB), intrinsically safe display screen (IB), and intrinsically safe push-button switch.

[0026] like Figure 1 As shown, the caster assembly 30 and the support foot assembly 40 are located at the bottom of the control base 21. The maximum height of the product is 1.9 meters. To ensure the stability of the product during placement, a storage and unfolding mechanism is designed, so that the product is stable during use and will not easily tip over due to external forces. It also provides a stable and safe lighting environment for the staff.

[0027] The support foot assembly 40 includes an active support foot 100 and a driven support foot 200. The bottom of the control base 21 is provided with a receiving groove 24 (e.g., Figure 2 As shown), the active support leg 100 and the driven support leg 200 can be accommodated in the receiving slot 24 based on the split-type rotation (as shown). Figure 3 (as shown) and can be expanded outside the receiving slot 24 (such as Figure 2 (As shown). Here, the term "side-by-side rotation" is explained by referring to the existing term "side-by-side refrigerator". The rotation connection point of the active support leg 100 and the rotation connection point of the driven support leg 200 are far apart from each other, while the free ends of the active support leg 100 and the free ends of the driven support leg 200 are close to each other.

[0028] When the operator applies force to the lifting push-pull rod 22, in conjunction with the caster assembly 30, the entire lighting fixture can be moved by pushing and pulling. At this time, the support leg assembly 40 is stored in the receiving slot 24; Figure 1 As shown, when the lighting fixture arrives at the designated location, the entire lighting fixture is in a vertical and stable position. The support leg assembly 40 can be unfolded to improve the support stability of the lighting fixture.

[0029] The support foot assembly 40 also includes a transmission gear set 300 (such as...). Figure 4 (as shown) and trigger button 400 (as shown) Figure 1 As shown). Figure 4 As shown, the connecting end 110 of the active support foot 100 is rotatably disposed in the receiving groove 24 by the torsion spring 500. The torsion spring 500 is used to provide elastic force to the active support foot 100 so that the active support foot 100 has a tendency to expand outward from the receiving groove 24.

[0030] The connection end 210 of the driven support foot 200 (e.g.) Figure 4 As shown, the driven support leg 200 is rotatably disposed in the receiving groove 24, and the connecting end 210 of the driven support leg 200 and the connecting end 110 of the active support leg 100 form a mutual power transmission through the transmission gear set 300.

[0031] like Figure 2 As shown, the bottom of the control base 21 is provided with a slot 25, and the free end 120 of the active support leg 100 is provided with a floating buckle 130 that cooperates with the slot 25 (e.g., Figure 1 (As shown).

[0032] like Figure 3 As shown, when the active support leg 100 and the driven support leg 200 are housed in the receiving groove 24, the active support leg 100 is located at the opening of the receiving groove 24, and the driven support leg 200 is located inside the receiving groove 24.

[0033] The trigger button 400 is used to cause the latch 130 to disengage from the slot 25 (e.g.) Figure 1 and Figure 7 As shown), the elastic force of the torsion spring 500 causes the connecting end 110 of the active support foot 100 to rotate, and the power transmission of the transmission gear set 300 causes the connecting end 210 of the driven support foot 200 to rotate, thereby causing the active support foot 100 and the driven support foot 200 to unfold outside the receiving groove 24.

[0034] like Figure 4As shown, in this embodiment, the transmission gear set 300 includes a plurality of sequentially meshing gear units, the number of which is even. One gear unit is located at the connecting end 110 of the active support leg 100, and another gear unit is located at the connecting end 210 of the driven support leg 200. It can be understood that in the structural design of this invention, the rotation direction of the connecting end 110 of the active support leg 100 and the rotation direction of the connecting end 210 of the driven support leg 200 need to be opposite. For example, when the rotation direction of the connecting end 110 of the active support leg 100 is clockwise, then the rotation direction of the connecting end 210 of the driven support leg 200 needs to be adjusted to counterclockwise. Only in this way, based on the mutual transmission of power, can the unfolding and retracting actions of the support legs be realized.

[0035] Since the driven support leg 200 and the driving support leg 100 transmit power to each other based on the transmission gear set 300, they rotate simultaneously to unfold or retract. To prevent interference between the driven support leg 200 and the driving support leg 100 during rotation, in this embodiment, the length of the driven support leg 200 is less than the length of the driving support leg 100 (e.g., ...). Figure 2 , Figure 3 and Figure 4 (As shown). It should be noted that the support legs need to be as long as possible to improve the stability of the support after it is deployed.

[0036] Furthermore, the length of the driven support foot 200 is less than the length of the active support foot 100, which can also be understood as the length of the active support foot 100 being greater than the length of the driven support foot 200. During the storage of the support foot, the protruding free end 120 of the active support foot 100 can interfere with the worker's feet, providing guidance and reminders to the worker, allowing the worker to quickly determine the correct storage sequence and achieve rapid storage of the support foot. This will be explained in detail below.

[0037] The working principle of the aforementioned lighting fixture 10 with deployable support legs will be explained below: When the support leg needs to be unfolded from the receiving slot 24, the operator applies force by pressing the trigger button 400 with the foot. The trigger button 400 then causes the buckle 130 to disengage from the slot 25. At the moment the buckle 130 disengages from the slot 25, the elastic force stored in the torsion spring 500 is released and acts on the connecting end 110 of the active support leg 100, causing the connecting end 110 of the active support leg 100 to begin to rotate. During the rotation of the connecting end 110 of the active support foot 100, the connecting end 210 of the driven support foot 200 also begins to rotate based on the power transmission of the transmission gear set 300. Thus, the active support foot 100 and the driven support foot 200 can be simultaneously unfolded from the receiving groove 24. As can be seen, unlike traditional designs that require bending down to manually operate the support legs to unfold or retract, staff only need to stand upright and use the dust on their feet to apply force to the trigger button 400 to easily and quickly unfold the support legs. It should be noted that the transmission gear set 300 of the present invention, by setting several gear units, not only plays the role of mutual power transmission, but also plays a certain role of buffering. It can be understood that the sequential meshing of several gear units will form a certain rotational resistance, and the elastic force accumulated by the torsion spring 500 will be released slowly, so that the two support legs can be slowly unfolded, and the support legs will not spring open rapidly and cause injury to the human body. When it is necessary to store the support legs in the receiving slot 24, the staff will not actively distinguish the order in which the support legs are stored, and they will rotate any support leg at will. like Figure 5 As shown, when the worker's feet press down on the driven support foot 200, the active support foot 100 also starts to rotate at the same time based on the power transmission of the transmission gear set 300. During the storage process, the free end 120 protruding from the active support foot 100 will interfere with the worker's feet, making the worker's feet uncomfortable, and thus the support foot cannot be completely housed in the receiving groove 24. At this point, the staff will immediately realize the error and quickly remove the dust from the driven support foot 200. Based on the elastic force accumulated by the torsion spring 500, the active support foot 100 will start to unfold outward again. Based on the power transmission of the transmission gear set 300, the driven support foot 200 will unfold outward at the same time. Thus, the support foot will return to its original unfolded state. like Figure 6 As shown, the staff will then press their feet dust onto the active support foot 100. Since the free end 120 of the active support foot 100 will no longer interfere with the staff's feet dust, the two support feet can be smoothly stored in the receiving slot 24 based on the power transmission of the transmission gear set 300. When both support legs are fully retracted into the receiving slot 24, the buckle 130 will engage in the slot 25 to lock, and the elastic force of the torsion spring 500 will be temporarily stored and not released. Therefore, in this invention, during the process of storing the support legs, the staff can be effectively guided to quickly determine the correct storage order, thereby enabling the support legs to be stored quickly.

[0038] like Figure 7 As shown, in this embodiment, the trigger button 400 includes a button body 410 and a push rod 420 drivenly connected to the button body 410. The push rod 420 is movably received in the slot 25 by a spring 430. The button body 410 drives the push rod 420 to overcome the elastic force of the spring 430, so that one end of the push rod 420 extends out of the slot 25 (e.g., Figure 2 (As shown). Furthermore, an inclined guide surface 131 is formed on the end face of the latch 130 (as shown). Figure 1 As shown), during the storage process, the inclined guide surface 131 contacts the bottom of the control seat 21 and is subjected to force, thereby pressing down the buckle 130 to avoid it. When the buckle 130 is in place, it floats up under the force of the elastic element and is locked in the slot 25.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
