Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lamp. Background Technology

[0002] Existing lighting fixtures, such as tri-proof lights, are generally designed in a long strip shape. For example, Chinese utility model patent application number 202322492291.8 discloses a tri-proof light with good waterproof effect, which includes a shell. The shell includes a bottom shell and an upper cover. The bottom shell and the upper cover are connected by a buckle. The upper cover is provided with a buckle. The buckle is hinged to the bottom shell. The buckle and the buckle cooperate. The buckle includes a hinge part, a main body part and a snap-fit ​​part that are connected to each other. The hinge part is hinged to the upper cover and the snap-fit ​​part is snap-fitted to the buckle.

[0003] When the buckles of this type of tri-proof light are in the open position before the top cover is installed, they will naturally droop due to gravity, which will cause some obstruction to the installation of the top cover. In addition, there is a possibility that the buckles may be clamped between the top cover and the bottom shell due to misoperation during the installation of the top cover, thereby damaging the buckles.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a lamp that can avoid being obstructed by the buckle during installation and avoid damage to the buckle.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a lamp, comprising:

[0007] The base shell is used as the mounting base for external installation.

[0008] The lampshade is located at the bottom of the base; and

[0009] A latch that connects the base shell and the lampshade, the latch including a latch body and a resilient connecting part that connects the latch body and the base shell;

[0010] Its features are:

[0011] The connecting portion includes a first connecting arm rotatably connected to the bottom shell and an arm extending from the first connecting arm to the buckle body. The arm is arc-shaped and connected to the buckle body. The buckle can be in the following states:

[0012] Installation status: The lower end of the buckle body away from the arm is fastened to the lampshade, and the upper end of the buckle body near the arm is close to the bottom shell;

[0013] Open state: Along the width direction of the lamp, the arm extends from the first connecting arm away from the bottom shell, and the arm is in a downward convex arc shape, so that the upper end of the buckle body is away from the bottom shell; at this time, on the horizontal plane projection, along the width direction of the lamp, the projection of the lower end of the buckle body is located outside the bottom projection of the bottom shell.

[0014] By making the arm of the latch's connecting part arc-shaped, the stability of the latch during opening and normal installation can be increased, as well as the elasticity of the latch. When the latch is opened, the arm presents a downward convex arc shape, increasing the distance between the latch body and the bottom shell, ensuring that the lower end of the latch body is located on the outside of the bottom of the bottom shell. Subsequently, when the lampshade is installed upward with the bottom shell, the latch will not hinder the lampshade from moving upward to the bottom of the bottom shell, and the lampshade will not clamp the latch between itself and the bottom shell during the upward movement, thus damaging the latch.

[0015] Furthermore, when the buckle is in the installed state, on a vertical cross section extending along the width direction of the lamp, the angle between the line connecting the two ends of the arm and the horizontal direction is α, and α < 65°. The smaller α is, that is, the closer the upper end of the arm is to the bottom shell, the more stable the buckle is and the less likely it is to pop open.

[0016] Furthermore, to improve the stability of the latch body in the installed state, the two side walls of the bottom shell in the width direction are provided with avoidance grooves for avoiding the latch.

[0017] Furthermore, to facilitate the connection between the bottom shell and the latch and to limit the latch, the bottom shell includes a shell with a bottom opening and first flanges formed on opposite sides of the shell in the width direction. Each first flange has a claw on its top surface. Each latch corresponds to two claws spaced apart along the length direction of the lamp. The top of each claw forms a downwardly recessed groove, and the first connecting arm is engaged in the groove.

[0018] Furthermore, to facilitate the engagement of the latch body and the lampshade, the latch body includes a main body and a fastening portion formed at the lower end of the main body;

[0019] The lampshade includes a cover body and second flanges formed on opposite sides of the cover body in the width direction. The bottom surface of the second flange has a downwardly extending stop portion, and the fastening portion can be fastened to the inside of the stop portion in the width direction of the lamp.

[0020] Preferably, the fastening part extends a certain distance from the lower end of the main body to form a rolled edge, which mates with the stop part. The rolled edge not only facilitates the mating with the stop part, but also provides a rounded edge, preventing scratches on the lampshade.

[0021] Preferably, in the horizontal projection, along the width direction of the lamp, the projection of the second flange of the lampshade does not extend outward beyond the projection of the first flange of the bottom shell, further ensuring that it does not interfere with the buckle body during installation.

[0022] Furthermore, a first stop and a second stop are formed on the bottom surface of each first flange, the two stops are arranged at intervals along the width direction of the lamp, and the two stops extend downward from the bottom surface of the first flange, thereby forming a groove between the two stops;

[0023] The top surface of the second flange is formed with an upwardly extending rib, which can be inserted into the groove to achieve the pre-positioning of the lampshade and the bottom shell.

[0024] Furthermore, in order to ensure that the buckle body is stably and balancedly connected and rotated with the bottom shell, the arm has two parts, and the arm and the first connecting arm form a U-shape.

[0025] Furthermore, to facilitate the connection between the arm and the buckle body, the ends of the two arms away from the first connecting arm are bent towards each other to form a second connecting arm. The two second connecting arms extend towards each other. The main body is provided with a hollow connecting seat that mates with each second connecting arm. The second connecting arm is inserted into the connecting seat, thereby rotatably connecting with the main body.

[0026] Compared with the prior art, the advantages of this utility model are as follows: by making the arm of the connecting part of the buckle arc-shaped, the stability of the buckle when opening and normal installation can be increased, and the elasticity of the buckle can also be increased. When the buckle is opened, the arm presents a downward convex arc shape, increasing the distance between the buckle body and the bottom shell, ensuring that the lower end of the buckle body is located on the outside of the bottom of the bottom shell. Subsequently, when the lampshade is installed upward with the bottom shell, the buckle will not hinder the lampshade from moving upward to the bottom of the bottom shell, and the lampshade will not clamp the buckle between itself and the bottom shell during the upward movement, thus damaging the buckle.

[0037] See Figures 1-8 A type of lighting fixture, primarily referring to a strip-shaped tri-proof light, includes a base shell 1 and a lampshade 2. The base shell 1 is used for installation on an external mounting base, such as an indoor ceiling. The lampshade 2 is located at the bottom of the base shell 1 and is used for emitting light. The space enclosed by the base shell 1 and the lampshade 2 can be used to house the light source, reflector, control circuit board, etc.

[0038] The base shell 1 and the lampshade 2 are installed together by a latch 3, which can be installed along the length of the entire lamp fixture. Figure 1 Multiple lamps are arranged at intervals (in the direction indicated by the middle arrow X), and along the width direction of the lamps (…). Figure 1The latches 3 are symmetrically arranged in the direction indicated by the middle arrow Y. In this embodiment, the bottom shell 1 includes a shell 11 with a bottom opening and first flanges 12 formed on opposite sides of the shell 11 in the width direction (the same as the width direction of the lamp). The two first flanges 12 extend in a direction away from each other. In the normal installation state, the first flanges 12 can extend horizontally or nearly horizontally. The bottom surface of each first flange 12 has a first stop 131 and a second stop 132. The two stops are arranged at intervals along the width direction of the lamp and extend downward from the bottom surface of the first flange 12, thereby forming a groove 14 between the two stops. In this embodiment, the first stop 131 is close to the outer edge of the first flange 12, and the second stop 132 is close to the inner edge of the first flange 12. The top surface of each first flange 12 is provided with a claw 15. Each latch 3 corresponds to two claws 15 arranged at intervals along the length direction of the lamp. The top of each claw 15 forms a downwardly recessed groove 151.

[0039] The lampshade 2 includes a cover body 21 and second flanges 22 formed on opposite sides of the cover body 21 in the width direction (the same as the width direction of the lamp). The top surface of the second flanges 22 has an upwardly extending rib 23 that can be inserted into the groove 14 to achieve pre-positioning when installed with the base shell 1. The bottom surface of the second flanges 22 has a downwardly extending stop portion 24 that can correspond to the outermost side of the second flanges 22 furthest from the cover body 21.

[0040] Each latch 3 includes a latch body 31 and a connecting portion 32. The latch body 31 includes a main body 311, an operating portion 312 formed at the upper end of the main body 311, and a fastening portion 313 formed at the lower end of the main body 311. The main body 311 and the operating portion 312 have a generally sheet-like structure, and the main body 311 may have a certain curvature. The fastening portion 313 is formed by bending and extending a certain distance from the lower end of the main body 311 to form a rolled edge 3131. The connecting portion 32 has a certain elasticity, such as being made of steel wire, and is generally U-shaped, with its open end facing the main body 311 of the latch body 31. The connecting portion 32 includes two arms 321 and a first connecting arm 322 formed between the corresponding ends of the two arms 321. The first connecting arm 322 can be engaged in the claw 15. The ends of the two arms 321, away from the first connecting arm 322, are bent towards each other to form second connecting arms 323. The two second connecting arms 323 extend towards each other. The main body 311 (especially near its upper end) is provided with a hollow connecting seat 3111 that mates with each second connecting arm 323. The second connecting arm 323 can be inserted into the connecting seat 3111, thereby rotatably connecting with the main body 311. The arm 321 is arc-shaped, which can increase the stability of the buckle 3 when it is opened and during normal installation, and also increase the elasticity of the buckle 3. When the buckle 3 is opened, it increases the distance between the buckle body 31 and the bottom shell 1.

[0041] The two side walls of the housing 11 in the width direction are provided with clearance grooves 111 for avoiding the buckle 3.

[0042] When the lampshade 2 needs to be installed, the latch 3 is in the open state. At this time, the arm 321 of the connecting part 32 of the latch 3 extends from the claw 15 away from the bottom shell 1. The arm 321 is in a downwardly convex arc shape, and the end that connects to the latch body 31 is higher than the end that connects to the first connecting arm 322. The operating part 312 of the latch body 31 gradually extends upward from the upper end of the body 311 away from the bottom shell 1. The length of the arm 321 is set such that when the connecting part 32 rotates downward relative to the claw 15 to the maximum angle (at this time, the arm 321 abuts against the first flange 12 near the outer edge; if it continues to rotate downward, the angle is greater than...). Figure 6 As shown, the first connecting arm 322 will disengage from the claw 15 upwards. Even under the gravity of the latch body 31, on the horizontal projection, along the width direction of the lamp, the projection of the lower end of the latch body 31 is located outside the bottom projection of the bottom shell 1 (outer side refers to the side away from the middle position along the width direction of the lamp, such as...). Figure 6 As shown, the projection of the lower end of the latch body 31 on the left is located to the left of the projection of the first flange 12 on the left. The second flange 22 of the lampshade 2 does not protrude beyond the first flange 12 in the width direction of the lamp, so it is sufficient to ensure that the projection of the lower end of the latch body 31 is located outside the projection of the bottom of the bottom shell 1. Then, the lampshade 2 is moved upward until it is pre-positioned with the bottom shell 1. During this process, the latch 3 will not obstruct the lampshade 2, and the lampshade 2 will not squeeze the latch 3, causing damage to the latch 3. Then, the upper end of the latch body 31 of the latch 3 is pressed into the relief groove 111 of the bottom shell 1. As a result, the fastening part 313 of the latch body 31 gradually approaches the second flange 22 of the lampshade 2 upward and inward. It is then forcefully pushed past the stop part 24 on the second flange 22, so that the fastening part 313 is fastened to the inner side of the stop part 24 (inner side along the width direction of the lamp), thus completing the installation of the lampshade 2. The elasticity of the connecting part 32 keeps the latch 3 in its current state. In the installed state, on a vertical cross section extending along the width of the lamp, the angle between the line connecting the two ends of the arm 321 and the horizontal direction is α, and α < 65°. The smaller α is, that is, the more the upper end of the arm 321 moves into the clearance groove 111, the more stable the state and the less likely it is to bounce off.

[0043] When disassembly is required, the latch 3 needs to be opened. At this time, press the operating part 312 downward so that the lower end of the latch body 31 is downward, thereby allowing the rolled edge 3131 of the lower end of the latch body 31 to disengage from the stop part 24, and thus open the latch 3.
