Description

Technical Field

[0001] This application relates to the field of lamps, and particularly to lamp lighting devices.

Background Art

[0002] In the field of lighting technology, lamps are indispensable equipment in daily life and industrial production. Components such as lamp shades and light sources of lamps need to be cleaned, replaced, or repaired due to dust accumulation, light attenuation, damage, etc. after being used for a certain period.

[0003] Currently, the removable structures used in commercially available lamps mainly have the following several typical forms and their inherent defects. The most traditional one is the screw fixation method that locks and fixes the lamp assembly to the base with multiple screws. This method realizes a reliable connection, but special tools such as a driver are required for removal, the operation procedure is cumbersome, not only does the maintenance time and labor cost increase, but it also brings greater inconvenience and safety risks in high-altitude work. Moreover, if the screws are tightened frequently, the screw threads are likely to slip, and the connection structure may be damaged.

[0004] Therefore, a lamp lighting device that can be quickly removed is required.

Means for Solving the Problems

[0006] The lamp lighting device provided by this application is a base, and a lamp assembly removably connected to the base. The lamp assembly includes a base plate and a lampshade, the lampshade being detachably connected to the base plate along the extending direction of the base plate, The aforementioned lighting device is The locking assembly is located on one side of the base plate opposite to the lampshade, and the locking plate is provided on the base, wherein the locking assembly includes a support rod and a torsion spring wound around the support rod, the torsion spring having a first elastic arm and a second elastic arm arranged in the opposite direction, and the distal ends of both the first and second elastic arms have engaging retaining portions extending toward the base plate. The locking plate has a strip-shaped groove positioned to face the torsion spring, the first elastic arm protrudes from one end of the strip-shaped groove, and the second elastic arm protrudes from the other end of the strip-shaped groove.

[Modes for carrying out the invention]

[0009] The embodiments of this application will be described below with reference to the drawings of the embodiments. It goes without saying that the embodiments described are only a part of the embodiments of this application, and not all of them.

[0010] Furthermore, when one component is considered to be "connected" to another component, that configuration may be directly connected to the other component, or there may be an intervening component present simultaneously. When one component is considered to be "placed" on another component, that configuration may be directly placed on the other component, or there may be an intervening component present simultaneously. Terms such as "top," "bottom," "up," "down," "left," "right," "front," and "back" used herein are for illustrative purposes only.

[0011] Several embodiments of this application will be described in detail below with reference to the drawings. Where there is no inconsistency, the following embodiments and their features can be combined with each other.

[0012] According to FIGS. 1 to 9, the lamp lighting device 100 provided by the embodiment of the present application includes a base 10, a lamp assembly 20, a locking assembly 30, and a locking plate 40.

[0013] Here, the lamp assembly 20 is removably connected to the base 10. The lamp assembly 20 includes a base plate 21 and a lamp shade 22. The lamp shade 22 is removably connected to the base plate 21 along the extending direction of the base plate 21.

[0014] The locking assembly 30 is disposed on one side of the base plate 21 opposite to the lamp shade 22. The locking assembly 30 includes a support rod 31 and a torsion spring 32 wound around the support rod 31. The torsion spring 32 has a first elastic arm 321 and a second elastic arm 322 disposed facing backward. Both distal ends of the first elastic arm 321 and the second elastic arm 322 have an engagement holding portion 3211 extending toward the base plate 21.

[0015] The locking plate 40 is disposed on the base 10. A strip-shaped groove 41 is formed in the locking plate 40 so as to face the torsion spring 32. The first elastic arm 321 protrudes from one end of the strip-shaped groove 41, and the second elastic arm 322 protrudes from the other end of the strip-shaped groove 41.

[0016] When the lamp assembly 20 is disassembled in the vertical direction F1, the distal ends of the first elastic arm 321 and the second elastic arm 322 approach each other so that the engagement holding portion 3211 moves along the strip-shaped groove 41 and abuts against the edge of the locking plate 40.

[0017] Specifically, the detachment process of the lamp assembly 20 from the base 10 can be understood as a process in which the opening and closing of the first elastic arm 321 and the second elastic arm 322 cooperate with the strip groove 41 of the locking plate 40 by the drive of the torsion spring 32. Thereby, the first elastic arm 321 and the second elastic arm 322 can suspend the lamp assembly 20 and the base 10 along the vertical direction F1 when being removed.

[0018] Furthermore, the first elastic arm 321, the second elastic arm 322 and the torsion spring 32 are of an integral structure. The engagement holding portion 3211 is usually a bent or hook-shaped structure for cooperating with the locking plate 40. The locking plate 40 is fixed on the base 10, and the size and position of the strip groove 41 are arranged to face the torsion spring 32, so that the first elastic arm 321 and the second elastic arm 322 respectively protrude from both ends of the strip groove 41.

[0019] When installing the lamp assembly 20, the lamp assembly 20 is pushed along the vertical direction F1 toward the base 10. Due to the restoring force of the torsion spring 32, the first elastic arm 321 and the second elastic arm 322 tend to open again, and the engagement holding portions 3211 at the distal ends of both move along the direction away from the locking plate 40, so that the engagement holding portions 3211 gradually exceed the edge of the locking plate 40 and deviate from the opening position of the strip groove 41. Thereby, the first elastic arm 321 and the second elastic arm 322 elastically contact the plate surfaces at both ends of the strip groove 41 by using their own elastic forces, and press both ends of the strip groove 41, so that the locking plate 40 and the locking assembly 30 are fixed, and the assembly and positioning of the lamp assembly 20 and the base 10 are completed.

[0020] If it is necessary to remove the lamp assembly 20, the lamp assembly 20 is pulled along the vertical direction F1, and the edge of the strip groove 41 in the locking plate 40 functions to compress and guide the first elastic arm 321 and the second elastic arm 322, bringing their distal ends closer together and driving the engaging retainer 3211 to move toward the locking plate 40, so that the engaging retainer 3211 re-enters the opening area of ​​the strip groove 41, forming an engagement with the edge of the locking plate 40, and the base 10 is separated from the lamp holder assembly.

[0021] Furthermore, by utilizing the continuous elastic clamping force provided by the torsion spring 32, the first elastic arm 321 and the second elastic arm 322 reliably contact and engage with the locking plate 40. On the other hand, in the disassembly process, the guiding and pressing of the edges of the strip groove 41 against the first elastic arm 321 and the second elastic arm 322 moves the engaging retaining portion 3211 to the fastening position on the locking plate 40, and by pushing and pulling the ramp assembly 20 in the vertical direction F1, the rapid assembly and disassembly of the ramp assembly 20 and the base 10 can be completed.

[0022] In one specific embodiment, the locking plate 40 has an engaging portion 42. Specifically, the locking plate 40 has a plate-like structure, and when viewed along the length of the strip-shaped groove 41, a plate surface structure is formed as an engaging portion 42 at a position adjacent to the free edge of the locking plate 40 at one end of the strip-shaped groove 41. The engaging portion 42 is provided continuously with the end of the strip-shaped groove 41 and is used to provide a dedicated contact and engagement area.

[0023] Furthermore, the distal ends of the first elastic arm 321 and the second elastic arm 322 of the torsion spring 32 are bent or processed into a hook shape to form an engagement retaining portion 3211, and the engagement retaining portion 3211 has a bent or hook-shaped end that protrudes in the direction toward the locking plate 40. When the lamp assembly 20 is pulled off from the installed state along the vertical direction F1, the engagement retaining portion 3211 gradually approaches the locking plate 40 as the first elastic arm 321 and the second elastic arm 322 swing. During the removal process, contact and engagement occur between the plate surface and the hook-shaped end of the engagement retaining portion 3211 and the engagement portion 42 provided at one end of the strip-shaped groove 41, and a secure engagement relationship is formed between the plate surface structure of the locking plate 40 and the engagement retaining portion 3211.

[0024] In one specific embodiment, when viewed from above along a direction perpendicular to the plate surface of the base plate 21, the support rod 31 is positioned in the center of the strip-shaped groove 41, and the first elastic arm 321 and the second elastic arm 322 extend from both sides of the support rod 31, facing each other along the length of the strip-shaped groove 41.

[0025] Specifically, the support rod 31 is positioned in the center of the strip groove 41 as the rotation center of the torsion spring 32, ensuring that the first elastic arm 321 and the second elastic arm 322 have equal lever arm lengths. In the assembled state, the two elastic arms extend from the support rod 31 toward both ends of the strip groove 41, and their extension paths coincide with the length of the strip groove 41. When the ramp assembly 20 is subjected to a vertical disengagement force F1, the two elastic arms can undergo elastic deformation of equal magnitude and in opposite directions, so that the movement trajectory of the engagement retaining portion 3211 within the strip groove 41 is kept symmetrical.

[0026] Furthermore, when the ramp assembly 20 is pushed toward the base 10, the two elastic arms of the torsion spring 32 simultaneously contact and are pressed against the side edges of the strip groove 41, causing them to elastically deform symmetrically. Because the support rod 31 is located in the center of the strip groove 41, this symmetrical deformation allows the two engaging retainers 3211 to synchronously straddle the edges of the locking plate 40, resulting in smooth engagement. During the removal process, when a vertical tensile force is applied, the guiding force exerted by the edges of the strip groove 41 on the two elastic arms is equal in magnitude, allowing the distal ends of the two elastic arms to be brought evenly together.

[0027] In one specific embodiment, the first elastic arm 321 employs a multi-stage bending structure that sequentially includes a first connecting arm 3212 connected to the body of the torsion spring 32, a second connecting arm 3213 connected to the first connecting arm 3212, and an engaging retaining part 3211 connected to the second connecting arm 3213, along its longitudinal direction.

[0028] Here, there is an angle A between the first connecting arm 3212 and the second connecting arm 3213, and an angle B between the second connecting arm 3213 and the engaging holding portion 3211. The opening of angle A is directed toward one side of the base plate 21, and the opening of angle B is directed toward the engaging portion 42.

[0029] Specifically, the two-stage bending design causes the first connecting arm 3212 to extend substantially along the length of the strip groove 41, the second connecting arm 3213 to form a transition in the direction approaching the base plate 21, and the engaging retaining portion 3211 to be positioned in the direction approaching the engaging portion 42, thus giving the first elastic arm 321 a spatially zigzag orientation. The double-angle structure in the opening direction ensures a smooth and stable interaction between the engaging retaining portion 3211 and the engaging portion 42 in the force transmission path of the first elastic arm 321 during the removal process.

[0030] In one specific embodiment, the locking assembly 30 further comprises a mounting plate 33 for supporting the torsion spring 32.

[0031] The mounting plate 33 is fixed to the base plate 21 and may be a plate-like structure that is in close contact with the base plate 21. The plate surface of the mounting plate 33 is parallel to the base plate 21, and the entire side of the mounting plate 33 opposite to the base plate 21 extends outward to form the first support plate 331 and the second support plate 332, both of which are erected along a direction perpendicular to the plate surface of the mounting plate 33 and maintain a constant distance from each other. The support rod 31 passes through the first support plate 331 and the second support plate 332 in order, and both ends are supported by the first support plate 331 and the second support plate 332 respectively. The spring coil of the torsion spring 32 is fitted onto the center of the support rod 31 and is restricted between the first support plate 331 and the second support plate 332, so that when the torsion spring 32 is in operation it always swings between the two support plates with the support rod 31 as the axis of rotation, avoiding axial jumping and displacement.

[0032] In one specific embodiment, when the lamp assembly 20 is disassembled in the vertical direction F1, the strip groove 41 passes through the first connecting arm 3212, the angle A between the first connecting arm 3212 and the second connecting arm 3213, and the second connecting arm 3213 in sequence until one end of the strip groove 41 abuts against the second connecting arm 3213, and one side of the engaging portion 42 away from the strip groove 41 abuts against the engaging holding portion 3211.

[0033] Furthermore, as the ramp assembly 20 is pulled along the vertical direction F1 and gradually moves away from the base 10 relative to the locking plate 40, it is understood that one end of the strip groove 41 slides along the broken contour of the first elastic arm 321, sequentially toward the first connecting arm 3212, angle A, and the second connecting arm 3213, and finally abuts toward the second connecting arm 3213. Simultaneously, the engaging retaining portion 3211 at the distal end of the second connecting arm 3213 bends toward the engaging portion 42 due to the elasticity of the torsion spring 32 and the geometric constraints of the broken line. When one end of the strip groove 41 contacts the second connecting arm 3213, the side of the engaging portion 42 on the outside of the strip groove 41 that is away from the strip groove 41 contacts the bent or hook-shaped end of the engaging retaining portion 3211, forming a stable fit between the end of the strip groove 41 and the second connecting arm 3213, and a stable fit between the engaging portion 42 and the engaging retaining portion 3211.

[0034] In this embodiment of the present application, a single locking assembly 30 is provided with two torsion springs 32, which are coaxially fitted onto the same support rod 31 and are positioned on opposite sides along the longitudinal direction of the support rod 31. Two corresponding locking plates 40 are also provided on the base 10, facing each other.

[0035] In one specific embodiment, the mounting plate 33 has a fixing groove 333 that extends along the length of the lamp, and the opening of the fixing groove 333 is open toward one side of the edge of the mounting plate 33.

[0036] The base plate 21 is provided with a projection block 211 that extends along a plate surface perpendicular to the base plate 21, and the projection block 211 is inserted into the fixing groove 333.

[0037] Specifically, the fixing groove 333 is U-shaped or has a concave groove structure. A projection block 211 is formed that protrudes overall from one side of the plate surface of the base plate 21, close to the area where the locking assembly 30 of the base plate 21 is located. The projection block 211 extends from the base plate 21 in a direction perpendicular to the plate surface of the base plate 21, and its cross-sectional dimensions and shape are adapted to the lumen of the fixing groove 333.

[0038] In a specific embodiment, the groove walls of the fixing groove 333 can surround the projection block 211 from three sides, and in accordance with the close contact between the base plate 21 and the mounting plate 33, the mounting plate 33 is effectively restricted both in the direction perpendicular to the base plate 21 and in the length direction of the ramp, thereby preventing warping and relative slippage of the mounting plate 33.

[0039] In one specific embodiment, the locking plate 40 employs an L-shaped structure consisting of a contact portion 43 and a sliding portion 44 that are perpendicular to each other. The contact portion 43 is fixed to the base 10 by screw joining or welding, ensuring stable positioning of the locking plate 40. The plate surface of the sliding portion 44 is arranged parallel to the plate surface of the base plate 21, and a strip-shaped groove 41 is provided in the sliding portion 44.

[0040] Furthermore, after the contact portion 43 is fixed, the sliding portion 44 provides a guide plane for the locking operation of the torsion spring 32 due to its parallel spatial positional relationship with the base plate 21. A strip-shaped groove 41 is provided in the sliding portion 44, ensuring that the movement trajectories of the first elastic arm 321 and the second elastic arm 322 within the strip-shaped groove 41 are always kept parallel to the base plate 21, thereby effectively avoiding the catching phenomenon due to angular misalignment.

[0041] In one specific embodiment, the lampshade 22 is composed of a light-transmitting portion 221 having an arc-shaped cross-sectional structure and extension portions 222 arranged at both ends of the light-transmitting portion 221.

[0042] Specifically, the light-transmitting portion 221 functions as the main illumination area, and the extension portion 222 is formed extending horizontally from both ends of the light-transmitting portion 221. When viewed from the vertical direction F1, the extension portion 222 extends from both ends of the light-transmitting portion 221 and protrudes into the housing cavity 11 surrounded by the base 10 to form a plug-in fitting, and is further attached and fixed by the locking assembly 30.

[0043] In one specific embodiment, the extension portion 222 has a guide groove 2221 recessed along the extending direction of the lampshade 22.

[0044] Guide portions 212 are provided on both side edges of the base plate 21, and the guide portions 212 are restricted to slide within the guide grooves 2221, thereby allowing the lampshade 22 to slide relative to the base plate 21 along the extending direction of the base plate 21.

[0045] Specifically, the cross-sectional shape of the guide groove 2221 is preferably dovetail or T-shaped in order to ensure good guiding effect and fall prevention performance.

[0046] In response to this, guide portions 212 are provided on both side edges of the base plate 21, which are aligned with the guide grooves 2221, and the shape and dimensions of the guide portions 212 form a sliding fit with the guide grooves 2221.

[0047] In the assembly process, by aligning the guide portions 212 on both sides of the base plate 21 with the guide grooves 2221 of the extension portion 222 of the lampshade 22 and applying a pressing force along the extending direction of the base plate 21, rapid assembly of the lampshade 22 and the base plate 21 can be achieved.

[0048] The above description is merely an embodiment of the present application, and those skilled in the art may make improvements, provided they do not deviate from the creative concept of this application, but it should be noted that all such improvements fall within the scope of protection of this application.
