Description

Technical Field

[0001] The utility model relates to the technical field of ceiling lamps, in particular to a self-locking installed ceiling lamp. Background Art

[0002] A ceiling light is a type of lamp. The top of the ceiling light is relatively flat, and the bottom is completely attached to the roof when installed. The ceiling light is generally composed of five major components: lampshade, chassis, baseboard, power supply, and light source.

[0003] Under the existing technology, the chassis is installed on the roof by screw connection. When the light source is damaged and a new light source is replaced (the light source is installed on the substrate, and the substrate is installed on the chassis), the chassis needs to be disassembled and reinstalled as a whole. Reinstallation requires the use of tools to adjust the ceiling lamp to a horizontal state, which increases the workload. At the same time, the large number of threaded connections makes it inconvenient to disassemble the chassis, and it takes a long time. Therefore, a technical measure is proposed to solve the problem that when the light source is damaged and a new light source is replaced, the chassis needs to be disassembled and reinstalled as a whole. Reinstallation requires the use of tools to adjust the ceiling lamp to a horizontal state, which increases the workload. At the same time, the large number of threaded connections makes it inconvenient to disassemble the chassis, and it takes a long time. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a self-locking ceiling lamp to solve the problem that under the prior art, when a light source is damaged and a new light source is replaced, the chassis needs to be completely disassembled and reinstalled, and the reinstallation needs to use tools to adjust the ceiling lamp to a horizontal state, which increases the workload. At the same time, the large number of threaded connections makes it inconvenient to disassemble the chassis, which takes a long time.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A self-locking ceiling lamp comprises a chassis, an upper surface of the chassis is provided with a groove, a mounting plate is engaged with the groove, a side surface of the mounting plate is provided with two groups of symmetrically distributed limiting holes, a self-locking component is slidably engaged with the limiting holes, an extrusion rod is threaded through the side surface of the chassis, and the front part of the extrusion rod is spherically arranged. Thanks to the arrangement of the self-locking component, when the chassis is pushed upward, the connection between the chassis and the mounting plate can be completed, and the chassis can be fixed. The installation is convenient, and when the bulb is replaced, the mounting plate does not need to be disassembled, so that when the chassis is reinstalled, there is no need to use tools to adjust the ceiling lamp to a horizontal state, thereby reducing the workload, and the number of threaded connections is small, and the replacement is fast.

[0007] Optionally, a circular hole is opened at the center of the chassis, and two groups of symmetrically distributed first threaded holes are opened on the side of the chassis. The threads of the first threaded holes are adapted to be fitted with screw rods, which are fixedly connected to the extrusion rod, and a rotating plate is connected to the end of the screw rod away from the extrusion rod.

[0008] Optionally, a base plate is installed inside the chassis, and a light bulb is installed on the lower surface of the base plate.

[0009] Optionally, a through hole is provided at the center of the mounting plate, and two groups of symmetrically distributed second threaded holes are provided on the upper surface of the mounting plate. Thanks to the provision of the through hole, it is convenient to pass the reserved wires through.

[0010] Optionally, the chassis is threadedly movably connected to a lampshade, and an upper portion of the lampshade is provided with a spiral tube threadedly connected to the chassis.

[0011] Optionally, the second threaded hole is threadably adapted to be fitted with bolts, and the mounting plate is fixed to the roof by the bolts.

[0012] Optionally, the self-locking component includes a vertical plate, which is fixedly mounted inside the mounting plate. Two groups of symmetrically distributed springs are provided on the upper end of the vertical plate. A card block is connected to the other end of the spring. The card block is large at the upper part and small at the lower part. The card block converges toward the lower part. Thanks to the setting of the spring, it is convenient to drive the card block to be stuck into the lower part of the extrusion rod.

[0013] Optionally, a card slot is provided on the upper portion of the card block, and the card slot is fitted with the extrusion rod.

[0014] Optionally, a connecting rod is installed at the lower part of the vertical plate, the other end of the connecting rod is connected to a rotating block, and the rotating block is rotatably connected to the side plate.

[0015] Optionally, the side plate is fixedly mounted on the lower part of the clamping block, and the clamping block is rotatably connected to the rotating block via the side plate.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by arranging a self-locking component, when the chassis is pushed upward, the connection between the chassis and the mounting plate can be completed, and the chassis can be fixed, which is convenient for installation. When replacing the bulb, the mounting plate does not need to be disassembled, so that when reinstalling the chassis, there is no need to use tools to adjust the ceiling lamp to a horizontal state, thereby reducing the workload. In addition, the number of threaded connections is small, and the replacement is fast. The groove on the chassis is aligned with the mounting plate and inserted. When the chassis is inserted into the mounting plate, the extrusion rod in the chassis moves upward and first contacts the lower end of the card block. When the extrusion rod continues to move upward, it squeezes the card block. Under the squeezing of the extrusion rod, the card block drives the side plate to rotate along the rotating block. When the card block rotates, the upper end compresses the spring, and the compression spring at the upper end of the card block enters the inside of the mounting plate. When the extrusion rod moves and contacts the card slot, the card slot enters the lower part of the extrusion rod under the drive of the spring rebound to complete the installation of the ceiling lamp.

[0018] By setting an extrusion rod, it is convenient to squeeze the self-locking component. When the chassis contacts the roof, the spring rebounds and drives the card block to be stuck into the lower part of the extrusion rod, thereby completing the connection and fixation between the chassis and the mounting plate.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it includes a chassis 1, a groove 5 is opened on the upper surface of the chassis 1, a mounting plate 3 is engaged with the groove 5, two groups of symmetrically distributed limiting holes 11 are opened on the side of the mounting plate 3, and a self-locking component 2 is slidably engaged with the limiting hole 11, an extrusion rod 15 is threaded through the side of the chassis 1, and the front part of the extrusion rod 15 is spherically set, a round hole 6 is opened at the center of the chassis 1, two groups of symmetrically distributed first threaded holes 7 are opened on the side of the chassis 1, the first threaded hole 7 is threadedly adapted with a screw 8, the screw 8 is fixedly connected to the extrusion rod 15, and a rotating plate 14 is connected to the end of the screw 8 away from the extrusion rod 15, a base plate 10 is installed inside the chassis 1, and a bulb 9 is installed on the lower surface of the base plate 10, a through hole 12 is opened at the center of the mounting plate 3, and two groups of symmetrically distributed second threaded holes 13 are opened on the upper surface of the mounting plate 3, a lampshade 4 is threadedly movably connected to the chassis 1, and a screw tube threadedly connected to the chassis 1 is provided on the upper part of the lampshade 4, and a second The threaded hole 13 is threadedly adapted with bolts, and the mounting plate 3 is fixedly mounted on the roof by means of bolts. The mounting plate 3 is installed and the mounting plate 3 is mounted on the roof by means of bolts and the second threaded hole 13. Subsequently, the reserved wires are passed through the through hole 12 to connect the lampshade 4 with the chassis 1. The reserved wires are passed through the round hole 6 to connect with the bulb 9 on the substrate 10 inside the chassis 1. Subsequently, the groove 5 on the chassis 1 is aligned with the mounting plate 3 and snapped in, completing the connection between the extrusion rod 15 and the self-locking component 2. When the bulb 9 is damaged, a tool is used to rotate the rotating plate 14 outward. The rotating plate 14 moves outward to drive the screw rod 8 and the extrusion rod 15 to move outward. The extrusion rod 15 moves outward to disengage from the contact with the block 206, thereby releasing the connection between the mounting plate 3 and the chassis 1. The chassis 1 is taken out to replace the bulb 9. Subsequently, the rotating plate 14 is rotated to restore the extrusion rod 15 to its original position, and the chassis 1 is snapped into the mounting plate 3 to complete the installation.

[0035] like Figures 1 to 5As shown, the self-locking component 2 includes a vertical plate 201, which is fixedly installed inside the mounting plate 3. Two groups of symmetrically distributed springs 203 are provided at the upper end of the vertical plate 201. The other end of the spring 203 is connected to a clamping block 206. The clamping block 206 is large at the upper part and small at the lower part. The clamping block 206 converges toward the lower part. A clamping groove 207 is opened at the upper part of the clamping block 206. The clamping groove 207 is clamped and matched with the extrusion rod 15. A connecting rod 202 is installed at the lower part of the vertical plate 201. The other end of the connecting rod 202 is connected to a rotating block 204. The rotating block 204 is rotatably connected to a side plate 205. The side plate 205 is fixedly installed at the lower part of the clamping block 206. The clamping block 206 is connected to the side plate 205 by The side plate 205 is rotatably connected to the rotating block 204, and the chassis 1 moves upward to drive the extrusion rod 15 to move upward. The extrusion rod 15 moves upward and first contacts the lower end of the block 206. When the extrusion rod 15 continues to move upward, it squeezes the block 206. Under the squeezing of the extrusion rod 15, the block 206 drives the side plate 205 to rotate along the rotating block 204. When the block 206 rotates, the upper end compresses the spring 203. The compressed spring 203 at the upper end of the block 206 enters the inside of the mounting plate 3. When the extrusion rod 15 moves and contacts the slot 207, the spring 203 rebounds and drives the lower slot 207 to enter the lower part of the extrusion rod 15 to engage, thereby completing the installation of the ceiling lamp.

[0036] The working principle provided by the utility model is as follows: firstly, the mounting plate 3 is installed, and the mounting plate 3 is installed on the roof by means of bolts and the second threaded hole 13 (tools are used to assist in ensuring the horizontal state of the mounting plate 3 during installation), and then the reserved wire is passed through the through hole 12, the lampshade 4 is connected to the chassis 1, and the reserved wire is passed through the round hole 6 to connect with the light bulb 9 on the base plate 10 inside the chassis 1, and then the groove 5 on the chassis 1 is aligned with the mounting plate 3 and inserted, and when the chassis 1 is inserted into the mounting plate 3, the extrusion rod 15 in the chassis 1 squeezes the self-locking component 2, and the specific method is that the chassis 1 is pressed toward The upward movement drives the extrusion rod 15 to move upward, and the extrusion rod 15 moves upward and contacts the lower end of the block 206 first, and the extrusion rod 15 continues to move upward to squeeze the block 206. The block 206 drives the side plate 205 to rotate along the rotating block 204 under the squeezing of the extrusion rod 15. When the block 206 rotates, the upper end compresses the spring 203, and the upper end of the block 206 compresses the spring 203 and enters the inside of the installation plate 3. When the extrusion rod 15 moves and contacts the slot 207, the spring 203 rebounds and drives the lower slot 207 to enter the lower part of the extrusion rod 15 to engage, thereby completing the installation of the ceiling lamp.

[0037] When the bulb 9 is damaged, use a tool to rotate the rotating plate 14 outward. The rotating plate 14 moves outward to drive the screw 8 and the squeezing rod 15 to move outward. The squeezing rod 15 moves outward to break away from the contact with the block 206, thereby releasing the connection between the mounting plate 3 and the chassis 1. The chassis 1 is taken out to replace the bulb 9. Then, the rotating plate 14 is rotated to restore the squeezing rod 15 to its original position, and the chassis 1 is stuck into the mounting plate 3 to complete the installation. Through the setting of the self-locking component 2, when the chassis 1 is pushed upward, the connection between the chassis 1 and the mounting plate 3 can be completed, and the chassis 1 can be fixed. The installation is convenient, and when replacing the bulb 9, the mounting plate 3 does not need to be disassembled, so that when reinstalling the chassis 1, there is no need to use tools to adjust the ceiling lamp to a horizontal state, thereby reducing the workload, and the number of threaded connections is small, and the replacement is fast.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
