US Classification:

359802

Abstract:

An adjustable magnifier structure mountable on various lamp stands, being comprised of a magnifier, an adjustable post, an extensible rod and a clamping portion, wherein, the extensible rod is provided on the two ends thereof with the magnifier and the extensible rod respectively. The magnifier can be rotated to any desired angular position, and the extensible rod can be adjusted in displacement freely, hence the adjustable post can be adjusted to any position in a three-dimensional space freely. The clamping portion is connectable with any of various lamp posts, so that the accompanied practical effect of various lamps can be increased by mounting a magnifier on any of them. The structure of the present invention is novel, convenient and practical in being mountable on these lamp stands without holding of a magnifier by a user.

International Classification:

F21V 2100

US Classification:

362287

Abstract:

A durable pivotal connecting device for a table lamp between a base and a supporting post of the lamp having a lampshade and a lamp pipe, the supporting post is connected to a rotation seat located in the base and is pivotably assembled with the durable pivotal connecting device for rotation adjustment of the supporting post; the connecting device includes two sets of curved spring leaves, two connecting rods, a transverse bar and an adjusting bolt. The spring leaves are arciform and symmetrically arranged, and each includes a connecting end and is split to form a slit, a positioning end and an adjustment end; screws are used to lock the connecting ends and the positioning ends of the spring leaves onto the inner wall of the base to pivotably mount the rotation seat; the adjustment ends are connected to the connecting rods and the transverse bar to make association of the two sets of spring leaves. The transverse bar has a guide hole allowing passing through of the stem of the adjusting bolt from outside of the base, in order that the transverse bar is moved up and down by adjustment of the adjusting bolt; the adjustment ends of the spring leaves can be operated to give elastic binding action force on the rotation seat, and durability of the pivot area requiring frequent adjustment between the base and the supporting post can be assured.

US Classification:

362253

Abstract:

A mounting device for a lamp on a birdcage comprised of a lamp receptacle provided on both ends thereof at least with a telescopically movable rod having a lock. Wherein, the locks can be hung and fixed on any positions on the frame of the birdcage; and by providing a plurality of telescopically movable rods, a lamp for the birdcage can be provided at a location on the frame of the birdcage requiring a light source. This can allow adjustment of distances and orientations of the light rays projected from the lamp to birds, thus growth of the birds can be promoted.
