Abstract

A ceiling lamp comprises a chassis, a lampshade, a base, and a light source board installed in the chassis, wherein a circular column ring is arranged on the base, a sleeve column inserted into the column ring is arranged on the top surface of the chassis, and the inner wall of the column ring and the outer wall of the sleeve column are screwed together by at least two sets of screw-fastening structures; a plurality of screw holes are arranged on the base, and since the chassis of the ceiling lamp is not directly fixed to the ceiling, but is installed to the ceiling through a small base, and then the chassis is fixed, the base does not need to be made too small like the chassis because a large light source board and a driving power supply need to be placed in the chassis, so the base can be made relatively small, so when installing the base, it can be completed by one person, thereby reducing the installation cost; at the same time, the structure of the utility model is more reasonable, and the installation and maintenance are convenient.

Description

ceiling lamp

technical field

The utility model belongs to a ceiling lamp.

Background technique

The current ceiling lamp mainly includes a chassis, a lampshade and a light source installed in the chassis. When installing the lamp, after fixing the chassis with 3-4 screws, put the lampshade up and tighten it. When installing the chassis, because the chassis is relatively large, it is often necessary for one person to support the chassis and tighten it to the ceiling, and then another person uses a screwdriver to tighten the screws one by one to fix the chassis. It can be seen that the current ceiling lamp The installation is inconvenient, and it needs two people to cooperate to complete it; if it is done by one person, when the first screw is finished, since only one point is positioned, it is easy to deform under the weight of the chassis itself, and even in severe cases. Damage to the luminaire, making it impossible to attach the lampshade. In addition, the space surrounded by 3-4 screw positions on the chassis is relatively large, so when some installation positions of the ceiling (such as corner positions) are not large enough, the ceiling lamp cannot be installed, so the current use of the ceiling lamp Occasions are easily restricted.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a ceiling lamp with a more reasonable structure, convenient installation and maintenance, and wider applicable occasions.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A ceiling lamp, comprising a chassis, a lampshade, a bottom bracket, and a light source plate installed in the chassis, a circular column ring is arranged on the bottom bracket, and a ring is inserted into the column ring on the top surface of the chassis. The set column is screwed together by at least two sets of turnbuckle structures between the inner wall of the column ring and the outer wall of the set column; a plurality of screw holes are provided on the bottom bracket.

In an improved solution to the above-mentioned ceiling lamp, the turnbuckle structure includes a turnbuckle provided on the outer end surface of the column and an arc-shaped swirl groove provided on the inner wall of the column ring and opening to one side.

In an improved solution to the above-mentioned ceiling lamp, a plurality of chassis screw holes are provided on the side of the chassis.

Compared with the prior art, the utility model has the beneficial effect: because the chassis of the ceiling lamp is not directly fixed to the ceiling, but is installed to the ceiling through a small bottom bracket and then the chassis is fixed, so the bottom bracket does not need to be fixed like the chassis because it needs to be fixed. A large light source board and a driving power supply are placed in the chassis and cannot be made too small, so that the bottom bracket can be made smaller, so when installing the bottom bracket, one person can complete the operation, which can reduce the installation cost; At the same time, the structure of the utility model is more reasonable, and the installation and maintenance are convenient.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

【Description of drawings】

Fig. 1 is a three-dimensional schematic diagram of an embodiment of the utility model;

Fig. 2 is a three-dimensional schematic diagram II of an embodiment of the utility model;

Fig. 3 is the first assembled schematic diagram of the utility model embodiment;

Fig. 4 is the second assembly diagram of the embodiment of the utility model.

【detailed description】

A ceiling lamp, as shown in Figures 1 to 4, includes a chassis 1, a lampshade 2, a bottom bracket 3, and a light source board (not shown in the figure) installed in the chassis 1. The shape of the bottom bracket is much smaller than that of the chassis. The bottom bracket 3 is provided with a circular collar 31, and the top surface of the chassis 1 is provided with a bushing 11 inserted into the collar 31, passing between the inner wall of the collar 31 and the outer wall of the collar. At least two sets of turnbuckle structures 4 are screwed together; multiple (3-4) screw holes 32 are provided on the bottom bracket 3, so that when installing the ceiling lamp, first use the screws to pass through the screw holes 32 to fix the bottom bracket 3 on the ceiling, and then hold up the whole ceiling lamp so that the sleeve column 11 on the top surface of the chassis 1 is aligned with the column ring 31 of the bottom bracket 3 and then inserted and tightened. As can be seen from the above, since the bottom bracket 3 is only used to fix the chassis, it does not need to be too small because a large light source board and a driving power supply are placed in the chassis 1 like the chassis, so the bottom bracket can be made It is relatively small, so when installing the bottom bracket, one person can complete the operation, which can reduce the installation cost; at the same time, because the bottom bracket takes up less space on the ceiling, even in some corner positions that are smaller than the space of the chassis , can install the ceiling lamp with the help of the bottom bracket, so the structure of the utility model is more reasonable, and the installation and maintenance are convenient.

In this embodiment, the turnbuckle structure 4 includes a turnbuckle 41 arranged on the outer end surface of the sleeve 11 and an arc-shaped swirl 42 arranged on the inner wall of the collar 31 and opening to one side, as shown in Figures 3 and 4 Show.

Preferably, as shown in Figures 2 and 3, a plurality of (generally 3-4) chassis screw holes 12 are provided on the side of the chassis 1, if screws pass through the chassis screw holes 12 to fix the chassis At the same time, it can be changed to the installation method of the ceiling lamp we have seen so far, so in actual use, the user can choose to use the chassis or the bottom bracket to install the ceiling lamp according to the needs, so that the application of the ceiling lamp is wider. ,Reasonable.

In this embodiment, the dome light is in the shape of a square, but it can also be in the shape of a circle, an oval, etc.

In summary, the above are only preferred embodiments of the present utility model, and are not intended to limit the implementation scope of the present utility model. That is, all equivalent changes and modifications made according to the patent scope of the utility model should belong to the technical category of the utility model.
