Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a lamp. Background Technology

[0002] A lighting fixture is an electrical device that transmits, distributes, and alters the light distribution of a light source. It generally includes a lamp holder, a light source installed inside the lamp holder, and a lampshade covering the bottom of the lamp holder. Traditional tri-proof lights connect the lamp housing and lampshade with screws. Although the screw connection makes the connection between the lamp housing and lampshade secure, it is extremely inconvenient to disassemble and assemble, requiring a lot of time and effort to remove and install the screws.

[0003] To facilitate maintenance, subsequent tri-proof lights adopted a snap-fit ​​connection between the lamp housing and the lamp cover. For example, the Chinese utility model patent "A Tri-proof Light with Mounting Bracket" with patent application number CN202220604348.1 (publication number CN217503430U) discloses a tri-proof light with mounting bracket, in which the lamp cover is mounted on the lower part of the lamp base through a snap-fit ​​assembly.

[0004] However, in the existing design, the lamp holder and lampshade are separate structures. This means that when replacing the lamp panel, performing maintenance, adjusting the color temperature, or adjusting the power, the lampshade needs to be removed, which is inconvenient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lamp that is simple to operate, based on the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a lamp, including a lamp holder with an opening at the bottom and a lamp cover covering the opening at the bottom of the lamp holder, characterized in that: the lamp holder and the lamp cover each have a first side and a second side arranged opposite to each other in the width direction, the first side of the lamp cover is rotatably connected to the first side of the lamp holder by a hinge structure, and the second side of the lamp cover is detachably connected to the second side of the lamp holder by a snap-fit ​​structure.

[0007] To achieve a rotatable connection between the lampshade and the lamp holder, the hinge structure includes:

[0008] A fixing base, disposed on the outer wall of the first side of the lamp holder, has a shaft hole extending along the length direction of the lamp holder; and

[0009] A rotating seat is provided on the outer wall of the first side of the lampshade and has a rotating shaft corresponding to the shaft hole. The rotating shaft is rotatably inserted into the corresponding shaft hole.

[0010] To prevent the lampshade from suspending in the air when laid flat, causing the rotating shaft to break, the axis of the shaft hole is offset from the outer wall of the fixed base, and the axis of the rotating shaft is offset from the outer wall of the rotating base. When the lampshade is fully open, the opening angle of the lampshade is >180°.

[0011] To ensure that the axis of the rotating shaft is offset from the outer wall of the rotating base, the rotating base also includes a connecting arm that extends outward from the outer wall of the lampshade and then toward the lamp base, and the rotating shaft is connected to the tail of the connecting arm.

[0012] To facilitate the installation and removal of the shaft while preventing it from easily detaching from the shaft hole, the following two solutions are available:

[0013] Option 1 is as follows: Each of the rotating shafts is connected to two connecting arms at both ends, and the two connecting arms are respectively located on both sides of the corresponding fixing seat. The top side of the fixing seat has a notch that communicates with the shaft hole, so that the corresponding rotating shaft can pass through and enter and exit the shaft hole.

[0014] To further prevent the rotating shaft from easily detaching from the shaft hole, an anti-detachment cover is also included. This anti-detachment cover is detachably connected to the outer wall of the first side of the lamp holder and has a limiting arm corresponding to the notch of the corresponding fixing seat. The end of each limiting arm is limited to the corresponding notch.

[0015] Option 2 is as follows: The end of the rotating shaft away from the connecting arm is provided with a first elastic locking foot that can pass through the corresponding shaft hole. The tail of the first elastic locking foot has a first fastening part, and the first fastening part and the connecting arm are respectively limited to the two sides of the corresponding fixing seat.

[0016] To achieve a rotatable connection between the lampshade and the lamp holder, the hinge structure includes:

[0017] A fixing base is provided on the outer wall of the first side of the lamp holder;

[0018] A pin, disposed on the fixing base, extends along the length direction of the lamp holder; and

[0019] A rotating seat is provided on the outer wall of the first side of the lampshade, and has a sleeve corresponding to the pin. The sleeve is rotatably fitted around the outer periphery of the corresponding pin.

[0020] In order to facilitate the installation and removal of the pin while preventing it from coming loose, each of the hinge structures has two fixed seats arranged at intervals along the front-back direction. Each fixed seat has a socket extending along the length of the lamp holder. The two ends of the pin are respectively inserted into the sockets of the two fixed seats, and at least one end of the pin is interference-fitted with the corresponding socket.

[0021] To prevent the lampshade from suspending in the air and causing the pin to break when the lampshade is laid flat, the axis of the pin is offset from the outer wall of the fixed base, and the axis of the sleeve is offset from the outer wall of the rotating base. When the lampshade is fully open, the opening angle of the lampshade is >180°.

[0022] To ensure that the axis of the sleeve is offset from the outer wall of the rotating base, the rotating base also includes a connecting arm that extends outward from the outer wall of the lampshade and then toward the lamp base, and the sleeve is connected to the tail of the connecting arm.

[0023] To achieve the snap-fit ​​connection between the lampshade and the lamp holder, the snap-fit ​​structure includes:

[0024] A fixing block is provided on the outer wall of the second side of the lamp holder; and

[0025] The second elastic locking foot is provided on the outer wall of the second side of the lampshade, and the tail has a second fastening part that can be fastened to the fixing block.

[0026] To prevent the second fastening part from easily detaching from the fixing block, the top of the fixing block has a first inclined surface that gradually rises from the inside out, and the bottom of the second fastening part has a second inclined surface that matches the first inclined surface. When the second fastening part is fastened onto the fixing block, the second inclined surface is positioned above the first inclined surface; or

[0027] The top of the fixing block has a convex first arc surface, and the bottom of the second fastening part has a concave second arc surface that matches the first arc surface. When the second fastening part is fastened to the fixing block, the second arc surface is positioned above the first arc surface.

[0028] To ensure that the second elastic locking foot has a certain degree of flexibility so that it can be deformed and detached from the fixing block by manual operation, the length of the second elastic locking foot is 15-25mm.

[0029] To facilitate finger insertion for operation, with the lamp holder mounted on the external mounting surface and the second fastening part fastened to the fixing block, the distance between the second elastic locking foot and the external mounting surface is denoted as d1, and the distance between the fixing block and the external mounting surface is denoted as d2, where d1 / d2 = 0.7 to 0.9.

[0030] Compared with the prior art, the advantages of this utility model are as follows: by connecting the first side of the lampshade to the first side of the lamp holder through a hinge structure, and detachably connecting the second side of the lampshade to the second side of the lamp holder through a snap-fit ​​structure, when it is necessary to open the lampshade, simply open the snap-fit ​​structure to allow the lampshade to flip downwards and remain in the open state. At this time, operations such as replacing the lamp panel, maintenance, adjusting the color temperature, and adjusting the power can be performed without removing the entire lampshade from the lamp holder, making the operation simple.

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0052] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0053] Example 1:

[0054] like Figures 1 to 6 The image shows a first preferred embodiment of the lamp fixture of this utility model. The lamp fixture includes a lamp holder 1, a lampshade 2, a hinge structure 3, and a snap-fit ​​structure 4. Both the lamp holder 1 and the lampshade 2 have a first side and a second side arranged opposite to each other along the width direction. In this embodiment, the first side and the second side are the left side and the right side, respectively.

[0055] The lamp holder 1 has an opening at its bottom.

[0056] The lampshade 2 is placed over the bottom opening of the lamp holder 1. The left side of the lampshade 2 is rotatably connected to the left side of the lamp holder 1 through the hinge structure 3, and the right side of the lampshade 2 is detachably connected to the right side of the lamp holder 1 through the snap-fit ​​structure 4.

[0057] There are three hinge structures 3, arranged at intervals along the front-to-back direction. Each hinge structure 3 includes a fixed base 31 and a rotating base 32. Specifically, the fixed base 31 is located on the outer wall of the left side of the bottom edge of the lamp holder 1, and has a shaft hole 311 extending in the front-to-back direction. The rotating base 32 is located on the outer wall of the left side of the top edge of the lamp cover 2, and includes a connecting arm 321 extending outward and then upward from the outer wall of the lamp cover 2, and a rotating shaft 322 connected to the tail and top of the connecting arm 321. The rotating shaft 322 corresponds to the shaft hole 311 and is rotatably inserted into the corresponding shaft hole 311. The axis of the shaft hole 311 is offset from the outer wall of the fixed base 31, and the axis of the rotating shaft 322 is offset from the outer wall of the rotating base 32, such as... Figure 6 As shown, when the lampshade 2 is fully open, the opening angle of the lampshade 2 is >180°, which can prevent the lampshade 2 from being suspended in the air when laid flat, thus preventing the pivot 322 from breaking.

[0058] In order to facilitate the installation and removal of the rotating shaft 322 while preventing the rotating shaft 322 from easily dislodging from the shaft hole 311, in this embodiment, each rotating shaft 322 is connected to two connecting arms 321 at its front and rear ends, and the two connecting arms 321 are respectively located on the front and rear sides of the corresponding fixing seat 31. The top side of the fixing seat 31 has a notch 312 that communicates with the shaft hole 311, which is used for the corresponding rotating shaft 322 to pass through and enter and exit the shaft hole 311.

[0059] There are three snap-fit ​​structures 4, arranged at intervals along the front-to-back direction. Each snap-fit ​​structure 4 includes a fixing block 41 and a second elastic snap-fit ​​foot 42. Specifically, the fixing block 41 protrudes from the outer wall of the right side of the bottom edge of the lamp holder 1, and the top of the fixing block 41 has a first inclined surface 411 that gradually rises from the inside to the outside. The head, i.e., the bottom end, of the second elastic snap-fit ​​foot 42 is connected to the outer wall of the right side of the top edge of the lamp cover 2 through a connecting part 421. The tail, i.e., the top end, of the second elastic snap-fit ​​foot 42 has a second fastening part 422 that can be fastened to the fixing block 41. The bottom of the second fastening part 422 has a second inclined surface 4221 that matches the first inclined surface 411. When the second fastening part 422 is fastened to the fixing block 41, the second inclined surface 4221 is limited to above the first inclined surface 411, which can prevent the second fastening part 422 from easily detaching from the fixing block 41.

[0060] In this embodiment, the length of the second elastic locking foot 42 is 15-25mm, which ensures that the second elastic locking foot 42 has a certain degree of toughness, so that it can be deformed and detached from the fixing block 41 by manual operation; in addition, as Figure 4As shown, with the lamp holder 1 installed on the external mounting surface and the second fastening part 422 fastened to the fixing block 41, the distance between the second elastic locking foot 42 and the external mounting surface is denoted as d1, and the distance between the fixing block 41 and the external mounting surface is denoted as d2, where d1 / d2 = 0.7 to 0.9. This ensures that when the lamp is installed in place, the second elastic locking foot 42 has sufficient clearance relative to the external mounting surface to facilitate finger insertion for operation.

[0061] Example 2:

[0062] like Figures 7 to 12 The image shown is a second preferred embodiment of the lamp fixture of this utility model. The difference from Embodiment 1 is that:

[0063] In order to facilitate the installation and removal of the rotating shaft 322 while preventing the rotating shaft 322 from easily detaching from the shaft hole 311, in this embodiment, the front end of the rotating shaft 322 is connected to the connecting arm 321, and the rear end of the rotating shaft 322 is provided with a first elastic locking foot 323 that can pass through the corresponding shaft hole 311. The tail of the first elastic locking foot 323, i.e. the rear end, has a first fastening part 3231. The connecting arm 321 and the first fastening part 3231 are respectively limited to the front and rear sides of the corresponding fixing seat 31.

[0064] Example 3:

[0065] like Figures 13 to 16 The image shown is a third preferred embodiment of the lamp fixture of this utility model. The difference from Embodiment 1 is that:

[0066] In this embodiment, there are six hinge structures 3, which are arranged at intervals along the front-to-back direction.

[0067] In this embodiment, each buckle structure 4 corresponds to two fixing blocks 41 arranged at intervals along the front-back direction. The top of each fixing block 41 has an outwardly convex first arc surface 412. The tail, i.e. the top, of each second elastic buckle foot 42 has two second fastening parts 422 arranged at intervals along the front-back direction. The bottom of each second fastening part 422 has an inwardly concave second arc surface 4222 that matches the first arc surface 412. When the second fastening part 422 is fastened to the fixing block 41, the second arc surface 4222 is limited to the top of the first arc surface 412, which can prevent the second fastening part 422 from easily detaching from the fixing block 41.

[0068] In this embodiment, the lamp also includes two anti-detachment covers 5, which are disposed above the fixing bases 31 of the foremost and rearmost hinge structures 3. Specifically, each anti-detachment cover 5 is detachably connected to the outer wall of the first side of the lamp holder 1 and has a limiting arm 51 corresponding to the notch 312 of the corresponding fixing base 31. The end of each limiting arm 51 is limited to the corresponding notch 312, further preventing the rotating shaft 322 from easily disengaging from the shaft hole 311.

[0069] Example 4:

[0070] like Figures 17 to 20 The image shown is the fourth preferred embodiment of the lamp of this utility model. The difference from Embodiment 1 is that:

[0071] In this embodiment, each hinge structure 3 further includes a pin 33. Specifically, each hinge structure 3 corresponds to two fixed seats 31 arranged at intervals along the front-back direction. Each fixed seat 31 has an insertion hole 313 extending along the front-back direction. The pin 33 extends along the front-back direction, and both ends of the pin 33 are respectively inserted into the insertion holes 313 of the two fixed seats 31. The peripheral wall of one end of the pin 33 has knurling 331 to make it interference fit with the corresponding insertion hole 313, thereby preventing the pin 33 from loosening. The rotating shaft 322 of the rotating seat 32 is replaced by a sleeve 324, which corresponds to the pin 33 and can be rotatably sleeved on the outer periphery of the corresponding pin 33. The axis of the aforementioned pin 33 is offset from the outer wall of the fixed seat 31, and the axis of the sleeve 324 is offset from the outer wall of the rotating seat 32. When the lamp cover 2 is fully open, the opening angle of the lamp cover 2 is >180°, which can prevent the lamp cover 2 from being suspended in the air when laid flat, thus preventing the pin 33 from breaking.

[0072] In this embodiment, each buckle structure 4 corresponds to two fixing blocks 41 arranged at intervals along the front-back direction. The top of each fixing block 41 has an outwardly convex first arc surface 412. The tail, i.e. the top, of each second elastic buckle foot 42 has two second fastening parts 422 arranged at intervals along the front-back direction. The bottom of each second fastening part 422 has an inwardly concave second arc surface 4222 that matches the first arc surface 412. When the second fastening part 422 is fastened to the fixing block 41, the second arc surface 4222 is limited to the top of the first arc surface 412, which can prevent the second fastening part 422 from easily detaching from the fixing block 41.

[0073] Taking Example 1 as an example, the working principle of this utility model is as follows:

[0074] (1) As Figure 4 As shown, the second fastening part 422 is fastened to the fixing block 41 to keep the lampshade 2 in the closed state;

[0075] To open the lampshade 2, simply insert your finger into the gap between the second elastic latch 42 and the external mounting surface, then pull the second elastic latch 42 outward to bend it to the right until the second latch 422 disengages from the fixing block 41. Figure 5 As shown, the lampshade 2 flips downwards under the action of gravity and remains in the open state, at which time operations such as replacing the lamp panel, maintenance, adjusting the color temperature, and adjusting the power can be performed;

[0076] (2) After the operation is completed, simply flip the lampshade 2 upwards. Under the pushing force of the fixing block 41, the second elastic locking foot 42 will bend and deform to the right until the second fastening part 422 passes over the fixing block 41. At this time, if Figure 4 As shown, the lampshade 2 returns to the closed state, and the second inclined surface 4221 is positioned above the first inclined surface 411, which can prevent the second fastening part 422 from easily disengaging from the fixing block 41.
