Description

Technical Field

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

[0002] Table lamps are an essential lighting device in daily life. To enhance stability during use, existing table lamps generally have counterweights in their bases. However, installing these counterweights typically requires drilling connecting holes in the counterweights. Users must align these connecting holes with the connecting holes on the connecting posts of the base before screwing in screws to secure the counterweights. This process requires manual alignment, which is cumbersome and time-consuming. Furthermore, the screws offer weak horizontal restraint on the counterweights, making them prone to horizontal movement and resulting in low installation stability. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a lamp holder that is convenient and time-saving to install the counterweight and has a high degree of installation firmness.

[0004] The purpose of this utility model is achieved as follows:

[0005] A lamp holder includes a lamp base and a counterweight. The lamp base has a mounting groove on its bottom surface, and a plurality of first connecting posts are provided on the mounting groove. The lamp holder further includes a first connecting member, the upper end of which has a first extension. The counterweight has a first inner groove on its bottom surface, and the bottom surface of the first inner groove has a first through hole extending to one side of the counterweight. The counterweight is placed on the mounting groove, and the first connecting posts are located inside the first through hole. The lower end of the first connecting member is inserted into the first through hole through the first inner groove and connected to the first connecting post. The first outer extension abuts against the bottom surface of the first inner groove; in this lamp holder, there is a large fitting space between the through hole extending to one side of the counterweight and the connecting post, allowing the user to fit the through hole and the connecting post in either the vertical or horizontal direction, making the installation and positioning of the counterweight on the outer shell more convenient and time-saving; furthermore, the contact area between the outer extension of the first connector and the first inner groove of the counterweight is large, which not only ensures the vertical restriction effect of the first connector on the counterweight, but also improves the horizontal restriction effect of the first connector on the counterweight, resulting in a high degree of firmness in the installation of the counterweight on the mounting groove.

[0006] The objective of this utility model can also be achieved by the following technical measures:

[0007] Specifically, the first inner groove is U-shaped, with one side of the first inner groove extending to one side of the counterweight; the U-shaped first inner groove has a simple structure and is relatively easy to manufacture; at the same time, the U-shaped first inner groove is also easy to process into the first through hole.

[0008] Specifically, from the bottom surface of the counterweight to the top surface of the counterweight, the side of the first inner groove is an inclined surface that slopes from the outside to the inside; so that the first inner groove is narrower at the top and wider at the bottom in the vertical direction, which facilitates the extension of the outer part of the first connector into the first inner groove, and also makes the fit between the outer part after extending into the first inner groove and the first inner groove stable.

[0009] Specifically, the first through hole is U-shaped, and the inner side of the U-shaped first through hole is close to the outer periphery of the first connecting post; this allows the first connecting post to restrict the counterweight in a part of the horizontal direction, which is beneficial to the stable installation of the counterweight on the mounting groove. At the same time, the U-shaped first through hole has a simple structure and is relatively easy to manufacture.

[0010] Specifically, the first connecting post is close to the side wall of the mounting groove, so that both the side of the first through hole and the side of the counterweight are close to the side wall of the mounting groove, thereby the side wall of the mounting groove can also restrict the counterweight in a part of the horizontal direction.

[0011] Specifically, the first connector includes a connecting screw and a washer. The first connecting post has a connecting hole. The washer is fitted onto the upper outer periphery of the connecting screw. The lower end of the connecting screw is inserted into the first through hole through the first inner groove and connected to the connecting hole. The lower surface of the washer abuts against the bottom surface of the first inner groove. The washer constitutes the first extension. The structure of the connecting screw and the washer is simple and easy to obtain. At the same time, the fit between the washer and the bottom surface of the first inner groove is good, which is conducive to the firm installation of the counterweight on the mounting groove.

[0012] Specifically, it further includes a second connector with a second extension at its upper end. A second connecting post is provided on the mounting groove. There are two counterweights. Each counterweight has a first inner groove and a first through hole on one side, and a U-shaped second inner groove on the other side. The bottom surface of the second inner groove has a semi-circular second through hole. The other sides of the two counterweights abut against each other and are placed together on the mounting groove. The second through holes of the two counterweights form a circular limiting space, and the second connecting post is located within the circular limiting space. The lower end of the second connector is inserted into the circular limiting space and connected to the second connecting post. The second extension abuts against the bottom surface of the second inner groove of the two counterweights. The second connector can simultaneously install and fix the two counterweights on the mounting groove. Its design is ingenious and its implementation effect is good. Furthermore, users can select the number and position of the counterweights according to the different weights of the lamp posts, making this lamp holder applicable to the installation needs of different lamp posts and with a wide range of applications.

[0013] Specifically, it further includes a third connector with a third extension at its upper end. A third connecting post is provided on the mounting groove, and the third connecting post is close to the side wall of the mounting groove. An arc-shaped third inner groove is provided on the other side of each counterweight. An arc-shaped third through hole is opened on the bottom surface of the third inner groove. The third through holes of the two counterweights form a U-shaped limiting space, and the third connecting post is located in the U-shaped limiting space. The lower end of the third connector is inserted into the U-shaped limiting space and connected to the third connecting post, and the third extension abuts against the bottom surface of the third inner groove of the two counterweights. This allows the third connector to simultaneously install and fix the two counterweights on the mounting groove, while the fit between the arc-shaped third through hole and the connecting post is less restrictive, making installation more convenient.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) In this lamp holder, there is a large fit space between the through hole extending to one side of the counterweight and the connecting post. Users can achieve the fit between the through hole and the connecting post in the vertical or horizontal direction, which makes the installation and positioning of the counterweight on the outer shell more convenient and time-saving. In addition, the contact area between the outer extension of the first connector and the first inner groove of the counterweight is large, which not only ensures the vertical restriction of the first connector on the counterweight, but also improves the horizontal restriction of the first connector on the counterweight, making the installation of the counterweight on the mounting groove more secure.

[0016] (2) The first connecting column can restrict the counterweight in part of the horizontal direction, which is conducive to the stable installation of the counterweight on the mounting groove. At the same time, the U-shaped first through hole structure is simple and easy to manufacture.

[0017] (3) The second connector can simultaneously install and fix two counterweights on the mounting slot. Its design is ingenious and the implementation effect is good. Furthermore, users can select the number and position of counterweights according to the different weights of the lamp posts, making this lamp holder applicable to the installation needs of different lamp posts and with a wide range of applications.
