A grid structure for lighting fixtures

Abstract

This utility model discloses a grille structure for lighting fixtures, including a lighting fixture. A grille is installed in the lower opening of the lighting fixture. A side lug is symmetrically and integrally installed on the inner wall of each end of the grille. This utility model aligns the four posts at the top of the grille with corresponding mating seats on the inner wall of the lighting fixture, allowing the posts to enter the mating seats. During the mating process, an upper retaining ring first presses two stops into the transverse cavity. After the upper retaining ring passes through the two stops, the stops return to their original position under the action of a spring, thus locking the stops in the gap between the upper and lower retaining rings. This allows the posts to be fixedly mated with the mating seats, enabling the grille to be smoothly installed at the opening end of the lighting fixture. This method only requires an upward thrust during installation to complete the mating between the grille and the lighting fixture, simplifying the mating process and making it more convenient for practical operation.

The structure of the fixing device is simple and novel, convenient to use and maintain, and more practical.

[0004] In practical applications, the mating end between the light fixture and the grille is often limited by the overall structural design of the equipment, leaving very little operating space. This makes the bolt alignment process difficult, and commonly used tools are also difficult to insert smoothly for tightening or disassembling. Sometimes, even special small tools are needed to barely complete the operation, making the mating between the light fixture and the grille inconvenient for actual operation. Utility Model Content

[0005] The purpose of this invention is to provide a grille structure for lighting fixtures, aiming to solve the problem that the connection between the lighting fixture and the grille is often limited by the overall structural design of the equipment, resulting in very little operating space. This makes bolt alignment difficult, and commonly used tools are also difficult to insert smoothly for tightening or disassembling operations, sometimes even requiring the use of special small tools to barely complete the task.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grille structure for a lamp, comprising a lamp, wherein a grille is installed in the lower opening of the lamp, and a side lug is integrally and symmetrically installed on the inner wall of each end of the grille;

[0007] A plug is rotatably connected to the outer wall of the side ear and the grille connection end. An upper retaining ring is fixedly sleeved on the outer wall of the plug near the top. A lower retaining ring is fixedly sleeved on the outer wall of the plug below the upper retaining ring. The connecting ends of the plug, the upper retaining ring and the lower retaining ring are inserted into the inside of the docking seat. One side of the docking seat is fixedly embedded in the inner wall of the lamp.

[0008] In order to allow the lower and upper retaining rings to pass smoothly through the block, as a grid structure for lighting fixtures according to this utility model, preferably, the outer walls of both the lower and upper retaining rings are arc-shaped, and the height of the lower retaining ring is twice the height of the upper retaining ring.

[0009] In order to enable the stop block to be locked between the lower stop ring and the upper stop ring, thereby fixing the insert post inside the docking seat, as a grid structure for lamps of this utility model, preferably, the center end of the docking seat is provided with a longitudinal cavity, and a transverse cavity is provided on the inner walls of both sides of the transverse center end of the longitudinal cavity, and the transverse cavity extends into the interior of the docking seat.

[0010] Each of the transverse cavities is equipped with a spring, one end of which is connected to one end of a stop block. The other end of the stop block has a semi-circular structure, and the semi-circular end of the stop block is inserted into the gap between the upper and lower stop rings.

[0011] In order to allow the insert to rotate so that the stop block can be pressed into the transverse cavity by the side block, thus allowing the insert to detach downward from the inside of the docking seat, as a grid structure for lighting fixtures according to this utility model, preferably, an arc-shaped side block is fixedly installed on each of the two outer walls of the lower stop ring, the outer wall of the side block is in contact with the inner wall of the longitudinal cavity, and the top of the side block is in contact with the bottom of the upper stop ring.

[0012] In order to enable the plug to rotate on the surface of the side ear, as a preferred embodiment of the grille structure for lamps of this utility model, a T-shaped cavity is formed at the bottom of the plug, a movable block is movably installed inside the T-shaped cavity, and the bottom of the movable block is fixedly installed on the surface of the side ear. The plug and the side ear are rotatably connected through the T-shaped cavity and the movable block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When aligning the grille with the bottom of the light fixture, align the four posts at the top of the grille with the corresponding mating seats on the inner wall of the light fixture. Then push the grille upwards, allowing the posts at the top of the grille to enter the mating seats. During the mating process, the upper retaining ring will first press the two stops into the transverse cavity. After the upper retaining ring passes through the two stops, the stops will return to their original position under the action of the spring, thus locking the stops in the gap between the upper and lower retaining rings. In this way, the posts can form a fixed connection with the mating seats, allowing the grille to be smoothly installed at the opening end of the light fixture. This method only requires applying an upward pushing force to complete the connection between the grille and the light fixture, thus simplifying the connection process and making it more convenient for practical operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a grille structure for a lamp, including a lamp 1, a grille 2 installed in the lower opening of the lamp 1, and a side ear 3 symmetrically and integrally installed on the inner wall of both ends of the grille 2.

[0023] A plug 4 is rotatably connected to the outer wall of the connection end of the side ear 3 and the grille 2. An upper retaining ring 5 is fixedly sleeved on the outer wall of the plug 4 near the top. A lower retaining ring 6 is fixedly sleeved on the outer wall of the plug 4 below the upper retaining ring 5. The connection end of the plug 4, the upper retaining ring 5 and the lower retaining ring 6 is inserted into the inside of the docking seat 7. One side of the docking seat 7 is fixedly embedded in the inner wall of the lamp 1.

[0024] Preferably, the outer walls of both the lower retaining ring 6 and the upper retaining ring 5 are arc-shaped, and the height of the lower retaining ring 6 is twice the height of the upper retaining ring 5.

[0025] In practical use, when the lower retaining ring 6 initially aligns with the longitudinal cavity 71 of the docking seat 7 along with the insertion post 4, the lower retaining ring 6 will smoothly enter the position of the stop block 74. As the lower retaining ring 6 begins to contact the stop block 74, the arc-shaped outer wall of the lower retaining ring 6 will be pressed against the semi-circular end of the stop block 74 under the action of external force. This causes the stop block 74 to gradually retract into the transverse cavity 72, allowing the stop block 74 to pass smoothly.

[0026] Preferably, a longitudinal cavity 71 is provided at the center end of the docking seat 7, and a transverse cavity 72 is provided on the inner walls of both sides of the transverse center end of the longitudinal cavity 71, and the transverse cavity 72 extends into the interior of the docking seat 7.

[0027] Each transverse cavity 72 has a spring 73 installed inside. One end of the spring 73 is connected to one end of the stop block 74. The other end of the stop block 74 has a semi-circular structure, and the semi-circular end of the stop block 74 is inserted into the gap between the upper stop ring 5 and the lower stop ring 6.

[0028] In practical use, after the upper retaining ring 5 passes through the stop block 74, the compression on the stop block 74 will disappear, and the spring 73 will promptly reset. When the spring 73 resets, it will push the stop block 74 out of the transverse cavity 72 again, and the semi-circular end of the stop block 74 will smoothly insert into the gap between the lower retaining ring 6 and the upper retaining ring 5. This achieves the locking effect on the insert post 4, fixing the insert post 4 inside the docking seat 7.

[0029] Preferably, an arc-shaped side block 61 is fixedly installed on each of the two outer walls of the lower retaining ring 6. The outer wall of the side block 61 is in contact with the inner wall of the longitudinal cavity 71, and the top of the side block 61 is in contact with the bottom of the upper retaining ring 5.

[0030] When it is necessary to remove the insert 4 from the docking seat 7, first rotate the insert 4. As the insert 4 rotates, it will rotate on the outer wall of the movable block 42 through the T-shaped cavity 41. After the insert 4 rotates smoothly, it will drive the side block 61 to rotate synchronously. When the side block 61 rotates, it will begin to squeeze the stop block 74. Finally, the stop block 74 will be squeezed and retracted into the transverse cavity 72. At this time, the rotation of the insert 4 will stop. During this step, the rotation angle of the insert 4 is 90°.

[0031] Next, pull the grille 2 down. When the grille 2 moves down, it will cause the insert 4 to disengage from the inside of the docking seat 7. In this way, the insert 4 and the docking seat 7 can be quickly disassembled during use.

[0032] Preferably, a T-shaped cavity 41 is formed at the bottom of the insertion post 4, and a movable block 42 is movably installed inside the T-shaped cavity 41. The bottom of the movable block 42 is fixedly installed on the surface of the side ear 3. The insertion post 4 forms a rotatable docking with the side ear 3 through the T-shaped cavity 41 and the movable block 42.

[0033] When aligning the grille 2 with the bottom of the lamp 1, align the four posts 4 at the top of the grille 2 with the corresponding mating seats 7 on the inner wall of the lamp 1. Then push the grille 2 upwards, allowing the posts 4 at the top of the grille 2 to enter the mating seats 7. During the alignment process, the upper retaining ring 5 will first press the two stops 74 into the transverse cavity 72. After the upper retaining ring 5 passes through the two stops 74, the stops 74 will return to their original position under the action of the spring 73, thus locking the stops 74 in the gap between the upper retaining ring 5 and the lower retaining ring 6. In this way, the posts 4 can form a fixed alignment with the mating seats 7, allowing the grille 2 to be smoothly installed at the opening end of the lamp 1. The above method only requires an upward pushing force to complete the alignment between the grille 2 and the lamp 1, thus simplifying the alignment process and making it easier to operate in practice.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
