Abstract
The utility model proposes a kind of length adjustment device for lamp bracket, comprise Compress Spring and be positioned at the screwed pipe in Compress Spring circle, one end of this screwed pipe described and the interior pitch thread of lamp bracket one end are connected and fixed, screwed pipe pipe shaft is through the mesopore of Lamp shade holder connecting portion, Lamp shade holder can be up and down, described Compress Spring to be enclosed within screwed pipe pipe shaft and between Lamp shade holder and lamp bracket, and adapts to the change of the spacing of Lamp shade holder that different lampshade length causes and lamp bracket because of the telescopic resilience of Compress Spring; The utility model is skillfully constructed, structure simple, is convenient to produce install, and is a kind of length adjustment device be widely used on lamp bracket.
Description
Technical field
The utility model relates to the adjusting device of lamp bracket, particularly a kind of be arranged on support lampshade lamp bracket on for regulating the device of stent length.
Background technology
At present, common a kind of light fixture comprises lamp bracket and is wrapped in the lampshade outside lamp bracket, this stent length is fixed usually, often be difficult to when lampshade length changes like this adapt to, the diversity of lampshade is also had higher requirement to the versatility of lamp bracket simultaneously, and existing regular length lamp bracket exists length to be fixed and the defect that can not regulate.
Summary of the invention
For addressing the aforementioned drawbacks, the utility model provides a kind of simple and reasonable for structure, length adjustment device for lamp bracket that security performance is high, easy to install and use.
The utility model solves the technical scheme that its technical problem adopts:
A kind of length adjustment device for lamp bracket, comprise Compress Spring and be positioned at the screwed pipe in Compress Spring circle, one end of this screwed pipe described and the interior pitch thread of lamp bracket one end are connected and fixed, the pipe shaft of this screwed pipe passes the mesopore of Lamp shade holder connecting portion, Lamp shade holder can be up and down, described Compress Spring to be enclosed within screwed pipe pipe shaft and between Lamp shade holder and lamp bracket, and adapts to the change of the spacing of Lamp shade holder that different lampshade length causes and lamp bracket because of the telescopic resilience of Compress Spring.
In the utility model, described screwed pipe is hard material, for hollow or solid, is full thread or partial threads, and this screwed pipe has nut to fix through the other end of Lamp shade holder connecting portion mesopore, and Lamp shade holder connecting portion can be avoided to depart from screwed pipe.
The beneficial effects of the utility model are: have employed Compress Spring due to the utility model and be positioned at the screwed pipe in Compress Spring circle, one end of this screwed pipe is fixing with being threaded of lamp bracket one end, screwed pipe pipe shaft is through the mesopore of Lamp shade holder connecting portion, and the connecting portion of Lamp shade holder is enclosed within can be up and down on screwed pipe pipe shaft; Compress Spring to be enclosed within screwed pipe pipe shaft and between Lamp shade holder and lamp bracket, because the telescopic resilience of Compress Spring and jack-up Lamp shade holder adapt to the change of the spacing of Lamp shade holder that different lampshade length causes and lamp bracket; Convenient, versatility is good, and production technology is simple, manufacturing cost is lower.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 adopts lamp installation figure of the present utility model;
Fig. 3 is the A enlarged drawing of Fig. 2;
Fig. 4 is the B enlarged drawing of Fig. 2.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of length adjustment device for lamp bracket, comprise Compress Spring (1) and be positioned at the screwed pipe (2) in Compress Spring circle, one end of described this screwed pipe (2) is fixing with being threaded of lamp bracket (3) one end, screwed pipe (2) pipe shaft is through the mesopore of Lamp shade holder (4) connecting portion (5), it is up and down that Lamp shade holder can overlap screwed pipe (2) pipe shaft, described Compress Spring (1) to be enclosed within screwed pipe (2) pipe shaft and to be positioned between Lamp shade holder (4) and lamp bracket (3), and because the telescopic resilience of Compress Spring (1) and jack-up Lamp shade holder adapt to the change of Lamp shade holder (4) that different lampshade length causes and the spacing of lamp bracket (3).
Because the utility model have employed the length adjustment device of compressed spring type, when lampshade is installed, one end of screwed pipe (2) rotates the one end being fixed on lamp bracket (3), Compress Spring (1) to be enclosed within screwed pipe (2) pipe shaft through Lamp shade holder (4) connecting portion (5) mesopore and to be positioned at Lamp shade holder (4) and lamp bracket (3), under the elastic force effect of Compress Spring (1), Lamp shade holder (4) is by jack-up, thus the final change adapting to different lampshade length and bring.Such structure installment is easy, strong adaptability, and production technology is simple, low cost of manufacture.
Wherein, screwed pipe (2) is for solid or hollow, and be full thread or partial threads, material is metal or nonmetal, the nut (6) of screwed pipe (2) one end and screwed pipe (2) pipe shaft can be one also can be split.
The utility model is simple and reasonable for structure, security performance is high, easy to install and use, be a kind of length adjustment device being widely used in lamp bracket.
More than that better enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
