Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an underground downlight. Background Technology

[0002] As a type of lighting fixture, in-ground downlights originated from the pursuit of higher lighting effects and innovation in the installation methods of lighting fixtures. Because they can be embedded in the ground or wall to achieve concealed lighting while providing a soft and uniform light effect, in-ground downlights have gradually gained market favor.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220269238U, which discloses a municipal in-ground light, including an in-ground light assembly. The in-ground light assembly includes an in-ground light housing, an annular slide rail fixedly mounted on the upper edge of the inner wall of the in-ground light housing, an annular in-ground light removable cover mounted slidably on the annular slide rail, a piston plate slidably mounted in the middle of the inner cavity of the in-ground light housing, a spring uniformly fixedly connected between the bottom surface of the piston plate and the bottom surface of the inner cavity of the in-ground light housing, and an in-ground light body provided in the middle of the upper surface of the piston plate.

[0004] As mentioned above, after the in-ground lights are placed, they are usually fixed with screws to ensure the stability of the lights. This installation process takes a lot of time, and the rust on the screws can also affect the disassembly efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an in-ground downlight to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an in-ground downlight, comprising a mounting cylinder and a lampshade, wherein the lampshade is slidably inserted into the interior of the mounting cylinder, and a lamp is installed inside the lampshade. The mounting cylinder and the lampshade are fitted with the same connecting assembly. The connecting assembly includes a mounting piece fixedly connected to the center of the outer circumference of the lampshade, a telescopic rod fixedly connected to the outside of the mounting piece, a snap-fit ​​connector fixedly connected to one end of the telescopic rod, and the same spring fixedly connected between the mounting piece and the snap-fit ​​connector, the spring surrounding the outside of the telescopic rod. The inner circumference of the mounting cylinder is provided with a snap-fit ​​groove adapted to the snap-fit ​​connector, and the snap-fit ​​groove is trapezoidal.

[0007] After the lampshade is inserted into the mounting cylinder, the two can be quickly connected, preventing the lampshade from easily detaching. The disassembly process is also relatively convenient, which helps to improve work efficiency. Applying external force to the clamping connector causes the spring to shorten under pressure. Then, insert the lampshade into the mounting cylinder. When the lampshade and the mounting cylinder come into contact, the clamping connector will also move to the corresponding position in the slot. The clamping connector is no longer restricted, and the spring drives the clamping connector into the slot, firmly restricting the position of the lampshade and making its state more stable. If you need to remove the lampshade, rotate the lampshade counterclockwise. The clamping connector will slide along the slope of the slot and then come into contact with the inner wall of the mounting cylinder. At this time, simply pull the lampshade upward to easily remove it.

[0008] As a further preferred embodiment of this technical solution, a waterproof component is installed at the bottom of the lampshade. The waterproof component includes a sealing cover placed at the bottom of the lampshade. The outer circumferential wall of the sealing cover and the outer circumferential wall of the lampshade are each provided with two extension plates. The same bolt is slidably inserted into the two extension plates, and each bolt is threaded with a nut.

[0009] Cover the opening at the bottom of the lampshade with the sealing cover, then pass the bolt through the two extension plates from top to bottom, and screw the nut on the outside of the bolt. Through the cooperation of the extension plates and the bolt, the sealing cover can be tightly fitted to the lampshade, so that the wire connection is in a sealed state, effectively preventing moisture from contacting the connection and causing short circuit of the lamp, which helps to improve the safety of the downlight.

[0010] As a further preferred embodiment of this technical solution, a rubber ring is adhered to both the top outer wall of the sealing cover and the bottom outer wall of the lampshade.

[0011] As a further preferred embodiment of this technical solution, two vertically arranged guide grooves are provided on the outer circumference of the mounting cylinder. The two guide grooves are respectively connected to two slots, and the depth of the guide grooves is less than the depth of the slots.

[0012] As a further preferred embodiment of this technical solution, the top outer wall of the mounting cylinder is provided with a plurality of equally spaced connection holes.

[0013] As a further preferred embodiment of this technical solution, the top of the outer circumference of the lampshade is provided with annularly distributed anti-slip textures.

[0014] As a further preferred embodiment of this technical solution, the end of the card connector is set to a round head.

[0015] This utility model provides an in-ground downlight, which has the following beneficial effects:

[0016] (1) By setting a connecting component, this utility model can quickly connect the lampshade and the mounting cylinder after the lampshade is inserted into the mounting cylinder, so that the lampshade will not easily come off and the disassembly process is also more convenient, which is conducive to improving work efficiency. Apply external force to the snap connector, the spring is shortened by the force, and then insert the lampshade into the mounting cylinder. When the lampshade and the mounting cylinder are in contact, the snap connector will also move to the position of the slot. The snap connector is no longer restricted. The spring drives the snap connector into the slot, and the position of the lampshade will be firmly restricted, making its state more stable. If the lampshade needs to be removed, rotate the lampshade counterclockwise, and the snap connector will slide along the slope of the slot and then contact the inner wall of the mounting cylinder. At this time, the lampshade can be easily removed by simply pulling it upward.

[0017] (2) By setting up a waterproof component, the sealing cover is placed over the opening at the bottom of the lampshade. Then, the bolt passes through the two extension plates from top to bottom, and the nut is screwed on the outside of the bolt. Through the cooperation of the extension plates and the bolt, the sealing cover and the lampshade can be tightly fitted, so that the wire connection is sealed. This effectively prevents water vapor from contacting the connection and causing the lamp to short circuit, which is beneficial to improving the safety of the downlight. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 3As shown in Figure 4, in this embodiment, an in-ground downlight includes a mounting cylinder 1 and a lampshade 2. The lampshade 2 is slidably inserted into the inside of the mounting cylinder 1, and a lamp is installed inside the lampshade 2. The mounting cylinder 1 and the lampshade 2 are equipped with the same connecting component 5. The connecting component 5 includes a mounting piece 501 fixedly connected to the middle of the outer circumference of the lampshade 2. A telescopic rod 502 is fixedly connected to the outside of the mounting piece 501. A snap connector 503 is fixedly connected to one end of the telescopic rod 502. The same spring 504 is fixedly connected between the mounting piece 501 and the snap connector 503. The spring 504 surrounds the outside of the telescopic rod 502. A slot 505 adapted to the snap connector 503 is opened on the inner circumference of the mounting cylinder 1, and the slot 505 is trapezoidal.

[0025] When an external force is applied to the locking connector 503, the spring 504 is shortened due to the force. Then, the lampshade 2 is inserted into the mounting cylinder 1. When the lampshade 2 and the mounting cylinder 1 are in contact, the locking connector 503 will also move to the corresponding position in the locking groove 505. The locking connector 503 is no longer restricted, and the spring 504 drives the locking connector 503 into the locking groove 505. The position of the lampshade 2 will be firmly restricted, making its state more stable. If the lampshade 2 needs to be removed, rotate the lampshade 2 counterclockwise. The locking connector 503 will slide along the slope of the locking groove 505 and then contact the inner wall of the mounting cylinder 1. At this time, the lampshade 2 can be easily removed by simply pulling it upward.

[0026] like Figure 1 As shown in Figure 2, a waterproof component 6 is installed at the bottom of the lampshade 2. The waterproof component 6 includes a sealing cover 601 placed at the bottom of the lampshade 2. The outer circumference of the sealing cover 601 and the outer circumference of the lampshade 2 are each provided with two extension plates 602. The same bolt 603 is slidably inserted into the two extension plates 602. Both bolts 603 are threaded with a nut.

[0027] A rubber ring 604 is bonded to the top outer wall of the sealing cover 601 and the bottom outer wall of the lamp cover 2. With their cooperation, the sealing performance between the sealing cover 601 and the lamp cover 2 is improved.

[0028] Cover the opening at the bottom of the lampshade 2 with the sealing cover 601, then pass the bolt 603 through the two extension plates 602 from top to bottom, and then screw the nut on the outside of the bolt 603. Through the cooperation of the extension plates 602 and the bolt 603, the sealing cover 601 can be tightly fitted to the lampshade 2, so that the wire connection is in a sealed state, effectively preventing moisture from contacting the connection and causing short circuit of the lamp, which is beneficial to improving the safety of the downlight.

[0029] like Figure 3As shown, two vertically arranged guide grooves 506 are provided on the outer circumference of the mounting cylinder 1. The two guide grooves 506 are connected to two slots 505 respectively, which can play a positioning role, thus eliminating the tedious alignment process. In addition, the depth of the guide groove 506 is less than the depth of the slot 505, preventing the connector 503 from entering the guide groove along the guide groove 506.

[0030] like Figure 3 As shown, the top outer wall of the mounting cylinder 1 has several equally spaced connecting holes 4. Bolts are passed through the connecting holes 4 to connect the mounting cylinder 1 to the ground, which helps to ensure the stability of the mounting cylinder 1.

[0031] like Figure 1 As shown in Figure 2, the top of the outer circumference of the lampshade 2 is provided with annularly distributed anti-slip textures 3, which helps to increase the friction between the lampshade 2 and the worker's hands, thus facilitating the disassembly and assembly work.

[0032] like Figure 4 As shown, the end of the connector 503 is rounded, which helps to reduce the friction between the connector 503 and the slot 505, thus making the disassembly of the lamp easier.

[0033] This utility model provides an in-ground downlight, the specific working principle of which is as follows:

[0034] When the device is in operation, after connecting the power supply wire and the lamp wire, place the connection point inside the lampshade 2. Then, cover the opening at the bottom of the lampshade 2 with the sealing cover 601. Next, pass the bolt 603 through the two extension plates 602 from top to bottom, and then screw the nut onto the outside of the bolt 603. Through the cooperation of the extension plates 602 and the bolt 603, the sealing cover 601 and the lampshade 2 are ensured to fit tightly, so that the wire connection is sealed. This effectively prevents moisture from contacting the connection and causing a short circuit in the lamp, which is beneficial to improving the safety of the downlight. Apply the snap-fit ​​connector 503. When an external force is applied, the spring 504 is shortened, and then the lampshade 2 is inserted into the mounting cylinder 1. When the lampshade 2 contacts the mounting cylinder 1, the locking connector 503 will also move to the corresponding position in the slot 505. The locking connector 503 is no longer restricted, and the spring 504 drives the locking connector 503 into the slot 505. The position of the lampshade 2 will be firmly restricted, making its state more stable. If the lampshade 2 needs to be removed, rotate the lampshade 2 counterclockwise. The locking connector 503 will slide along the slope of the slot 505 and then contact the inner wall of the mounting cylinder 1. At this time, the lampshade 2 can be easily removed by simply pulling it upward.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
