The fixed structure of the metal tube imitating the swan-shaped desk lamp

Abstract

The invention discloses a metal tube fixing structure of a swan-imitated-shaped table lamp. The metal tube fixing structure comprises a lamp head, a lamp base and a circular lamp post, wherein a metal tube is arranged in the lamp post in a penetration mode; the lamp post comprises a lamp post lower section and a lamp post upper section; outer threads are formed on the outer surface at the near end of the metal tube; the outer threads are screwed with a nut; each of the lamp base and the lamp post lower section is formed by jointing left and right half parts which are separately arranged; two transverse supporting sheets are integrated by the lamp post lower section at one side by injection molding; the lamp post lower section at the other side is formed with upper and lower semicircular circular-arc-shaped convex ribs which are formed by injection molding; the near end of the metal tube penetrates through the through holes in upper and lower transverse supporting sheets; the nut is positioned below the lower transverse supporting sheet; a ring-shaped metal blocking ring is further arranged at the upper end of the lamp post lower section in a sleeving mode; and a ring-shaped blocking edge bulged towards the central direction is formed at the lower edge of the metal blocking ring. According to the metal tube fixing structure, the metal tube can be fastened, and obvious seams are not formed in the lamp base and the lamp post lower section.

Description

technical field [0001] The invention belongs to the technical field of desk lamps, and in particular relates to a metal tube fixing structure of a swan-shaped desk lamp. Background technique [0002] The desk lamp comprises a lamp cap, a lamp holder, and a lamp post, the lamp post is connected between the lamp cap and the lamp holder, and electrical components are installed in the inner cavity of the lamp holder. The position and orientation of the lamp head of most table lamps can be adjusted, and the position and orientation of the lamp head of a small number of table lamps cannot be adjusted. If the position and orientation of the lamp head can be adjusted, it is common practice to install a bendable metal tube in the lamp post. Due to the heavy weight of the metal tube and the lamp cap suspended from its far end (that is, the end away from the lamp holder and close to the lamp cap), the weight of the lamp cap and the entire metal tube is relatively large, which also has...

Problems solved by technology

[0005] The above-mentioned structural characteristics make it difficult to fix the proximal end of the metal tube. The main reasons are as follows: Since the rear profile of the lower neck section and the trunk section present an acute angle, the lower section of the light pole (the lower section of the neck shell) cannot be injection molded into one body. Similarly, the left and right parts of the lamp holder (trunk shell) cannot be injection molded into one

Conversely, if the entire lower part of the light pole (the lower part of the neck shell) is injection molded into one body with the lamp holder (the trunk part shell), it will not be able to be demoulded smoothly due to the angle (can not find a direction that can be demoulded smoothly) )

Since the lower part of the light pole and the lamp holder cannot be injection molded into a complete cylinder, the applicant tried to separate the lamp holder and the light pole into two parts from the left and right directions, but this creates new problems: if the traditional fixing method is used, the The metal plate and the metal tube are assembled into an inverted T shape, and the metal plate is fixed on the trunk shell, then as the nuts are continuously tightened, the metal plate will generate a force on the lamp holder and the lower part of the lamp pole to split it to the left and right , due to the weight of the lamp holder and the entire metal tube and the large torque of the overturning tendency, the nuts need to be tightened very tightly, which means that the lamp holder and the lower section of the lamp pole will be subjected to a large splitting force in the left and right directions, and finally the lamp holder, The left and right petals of the lower section of the light pole produce obvious gaps, which affect the aesthetic and artistic effects
