1. Field of the Invention
The present invention is related to an illuminating lamp for an aquarium, and especially to an adjustable illuminating lamp for an aquarium of which the length can be adjusted to be adapted for aquariums of various sizes.
2. Description of the Prior Art
A conventional illuminating lamp for an aquarium generally is composed of a main body of a lamp shade in combining with a water-proof panel, the main body of the lamp shade is fixedly installed on its end with an electric member such as a set of transformer. On the end having the electric member such as the set of transformer, a connecting rod is extended outwards, and a clamping means is provided on the end of the connecting rod, the clamping means is used to clamp on the aquarium in order that a lamp pipe in the lamp shade emits light to illuminate a water surface.
Such a clamping means provided on one end is subjected to the gravity force of the entire lamp set of which the lamp shade is pended, after a period of time; it has a defect of being subjected to loosening and dropping. Particularly, when in installing on the aquarium, the clamping means provided on one end is very inconvenient for mounting because of its unbalanced designing.
The present invention mainly provides an adjustable illuminating lamp for an aquarium that mainly has an illuminating main body for receiving a lamp pipe, the illuminating main body is provided on its two lateral ends each with an extendible rod, the extendible rods can be adjusted in their distances from the illuminating main body, and the end of each extendible rod is provided with a clamping means to clamp on either of the lateral sides of the aquarium.
The main function of the present invention is to adjust the lengths of the extendible rods in pursuance of the size of the aquarium; thereby the present invention can be adapted for aquariums of various sizes. And the lamp set can be firmly fixed above a water surface.
Another function of the present invention is to adjust the length of clamping of the clamping means in pursuance of the thicknesses of the lateral plates of the aquarium by rotating bolt heads of locking bolts provided on the clamping means.
The lamp pipe in the illuminating main body of the present invention can be changed to two by amount according to need.
The present invention will be apparent in its structural features and functions in operation after reading the detailed description of the preferred embodiments thereof in reference to the accompanying drawings.
Referring to
Further referring to
The two lateral seats 12 are provided to obscure the lateral ends of the elongate lamp shade 11, they are fixed on the elongate lamp shade 11 each by screwing in a couple of screws 121 from outside for fixing, the heads of the screws 121 are covered with a lateral cover 122. The two sets of lamp heads 15 are mounted in arciform recesses 123 in the two lateral seats 12.
The upper lid 13 is engaged in the top surface of the elongate lamp shade 11 and has thereon an elongate slit for mounting a pair of hanging hooks 132.
The extendible rods 20 are U shaped rods, each of them has two elongate side rods 21 that extend through its corresponding lateral seat 12 and into the seats 14 with holes on the lower edges of the elongate lamp shade 11, taking advantage of the lengths of the elongate side rods 21 which can be extended in and out of the seats 14 with the holes, the distance from a transverse rod 22 of each extendible rod 20 to the elongate lamp shade 11 can be adjusted. And the transverse rods 22 of the extendible rods 20 are connected with the two clamping means 30 respectively.
The two clamping means 30 each has an inner seat 31 and an outer seat 32, the seats 31 and 32 are mutually connected and are fixed on the transverse rods 22 of the extendible rods 20. The inner seat 31 has on its lower side a protruding plate 312, a platform 313 extends inwards from the protruding plate 312 and is provided thereon with a through hole 311. An engaging plate 34 is provided inwardly of the inner seat 31 and is provided thereon with a hole 341 for a nut. The nut hole 341 can be mounted therein with a nut 342. A locking screw bolt 33 is extended from outside of the outer seat 32 into the through hole 311 of the inner seat 31 to be connected and locked with the nut 342 of the engaging plate 34. A head 331 of the locking screw bolt 33 is extended out of a round hole 321 of the outer seat 32 to allow holding of a finger to rotate the locking screw bolt 33, and further to adjust the distance between the engaging plate 34 and the protruding plate 312 of the inner seat 31; thereby the protruding plate 312 and the engaging plate 34 can hold either of the lateral sides 40 by clamping. And a slide-proof plate 35 having thereon slide-proof knurls is provided at a contact face between the engaging plate 34 and the lateral side 40.
As to the operation of assembling and detaching of the lateral sides 40 of the aquarium of the present invention, please refer to
Evidently, the clamping means 30 of the present invention can be used to adjust the head 331 of the locking screw bolt 33 in pursuance of the thicknesses of the lateral plates 40 of the aquarium, then the function of firmly clamping can be obtained.
And referring to
Certainly, the lamp pipe 16 in the illuminating main body 10 of the present invention can be changed by amount, referring to
My invention is to be construed as including all modifications and variations falling within the scope of the appended claims.
