Description

TECHNICAL FIELD

[0001] The utility model relates to lamp technical field, especially a lampshade compression ring locking structure. BACKGROUND

[0002] In order to prevent lampshade from loosening or falling off in the working process, affecting normal use of the lamp, manufacturers generally design a lampshade locking structure on the lamp cap, and the lampshade is fixed by clamping. There are several common lampshade locking structures: special buckle structure, spring piece fixing structure and locking compression ring structure. Among them, the buckle in the buckle structure is usually made of plastic, which is easy to damage during assembly and disassembly. The spring piece fixing structure is very firm, but it is not suitable for heavy lampshades. The locking compression ring structure is that a thread is formed on the lamp cap, and the lampshade is locked by a outer ring in a screw connection manner, which is also a commonly used way.

[0003] At present, the locking compression ring structure of the lamp on the market is more to press the lampshade by using plastic such as acrylic. For example, the Chinese invention patent application with patent announcement number CN110500561B discloses a glass lampshade lock structure, which comprises: a glass lampshade with a mounting through hole in the top center, a lock structure, the lock structure comprises a circular ring, a wire cutting part, a lampshade supporting bowl and an acrylic part, the wire cutting part is attached to the circular ring and fixed by a short screw, the wire cutting part is arranged below the glass lampshade, the lampshade supporting bowl is arranged above the glass lampshade, and the lampshade supporting bowl and the wire cutting part are fixed at the mounting through hole position by a long screw, an internal thread is arranged on the inner ring surface of the circular ring, an external thread ring is also arranged, the acrylic part is clamped into the circular ring, the external thread ring is threadedly connected with the internal thread of the circular ring, and the acrylic part is clamped and positioned by the external thread ring. It can not only realize the disassembly and assembly operation quickly and effectively, but also can ensure the stability and reliability of installation, has strong applicability and good practicability.

[0004] However, the existing structure still has the following disadvantages:

However, the lock structure has many parts, the installation is complex, and certain installation skills are required. In addition, the acrylic part made of plastic is easy to deform under high temperature during use of the lamp, which affects the service life of the lamp. If zinc alloy material is used for die casting, not only the material cost will increase, but also a large amount of waste will be generated, which increases the manufacturing cost and is not conducive to production management.
