Description

Technical Field

[0001] The utility model relates to the technical field of magnifying glass lamps, in particular to a retractable magnifying glass lamp. Background Art

[0002] A magnifying glass lamp is a special lamp that has both magnification and lighting functions. It is widely used in factory product inspection and product assembly, and is also used in the fields of medical treatment, beauty, electronics, handicrafts, philately or jewelry collection. Existing magnifying glass lamps generally include a lamp head, a base, and a connecting device connected between the lamp head and the base. For example, as shown in a Chinese patent for a flip cover structure of a magnifying glass lamp (CN201020117733.0), the connecting device includes two hinged lamp arms. The magnifying glass lamp adjusts the relative angle between the two lamp arms to adjust the height of the lamp head. In this way, the height adjustment operation of the lamp head is relatively troublesome and the height adjustment effect is poor, and there is room for improvement. Utility Model Content

[0028] In this embodiment, if Figure 2 , 7 and Figure 8 As shown, the magnifying glass 220 lamp also includes a swivel joint 400, the upper end of which is connected to the lamp head 200 for horizontal rotation, and the lower end of the swivel joint 400 and the upper end of the telescopic rod 300, as well as the lower end of the telescopic rod 300 and the base 100 are connected via a vertical deflection mechanism; the magnifying glass 220 lamp rotates 180° around the swivel joint 400 through the lamp head 200, and the telescopic rod 300 is deflected downward by 90° through the vertical deflection mechanism to lie on the upper surface of the base 100, and at the same time, the swivel joint 400 is deflected upward by 90° through the vertical deflection mechanism so that the lamp head 200 and the base 100 are basically kept horizontal, thereby realizing the folding and storage of the magnifying glass 220 lamp, greatly reducing the volume of the magnifying glass 220 lamp, so that it can be easily carried or stored.

[0029] In this embodiment, if Figure 3 and Figure 4As shown, the lower end of the telescopic rod 300 is provided with a lower U-shaped joint 340, and the rear end of the base 100 corresponding to its upper surface is provided with a lower mating joint portion 110 that extends into the notch of the lower U-shaped joint 340 and is rotatably connected through a connecting piece 500. The lower U-shaped joint 340, the lower mating joint portion 110 and the connecting piece 500 cooperate to form a vertical deflection mechanism; specifically, the connecting piece 500 includes a lock portion 510 and a rotating shaft portion 520 integrally connected to the lock portion 510, wherein the lock portion 510 is a regular polygonal structure and The diameter of its circumscribed circle is larger than the diameter of the rotating shaft portion 520; the lower U-shaped joint 340 is provided with a locking groove 341 for the lock portion 510 to be embedded in one side thereof to limit the rotation of the connecting member 500; a rotating channel H connected to the locking groove 341 and for the rotating shaft portion 520 to pass through is also formed between the lower U-shaped joint 340 and the lower mating joint portion 110; preferably, the rotating shaft portion 520 extends from one side of the U-shaped joint having the locking groove 341 and passes through the rotating channel H to the other side, and the end of the rotating shaft portion 520 is detachably connected with an anti-slip component 600, The other side of the U-shaped joint is correspondingly provided with a receiving groove 342 for accommodating the anti-slip member 600, and a spring 700 is sleeved on the rotating shaft portion 520 and the spring 700 is abutted and connected between the anti-slip member 600 and the bottom of the receiving groove 342, so that under the action of the spring 700, the lock head of the connecting member 500 can be firmly embedded in the locking groove 341, and at the same time, through the cooperation of the spring 700 and the anti-slip member 600, not only the risk of the entire detachment of the connecting member 500 causing the connection failure between the telescopic rod 300 and the base 100 is avoided, but also by controlling the movement change of the anti-slip member 600 in the receiving groove 342, it can be ensured that the lock head 510 slides out of the locking groove 341, so that the telescopic rod 300 and the base 100 can switch between the rotating state and the locked state, so that the state between the telescopic rod 300 and the base 100 can be easily adjusted.

[0030] In this embodiment, if Figure 3As shown, the lower end of the rotary joint 400 and the upper end of the telescopic rod 300 are deflected by a vertical deflection mechanism, and the vertical deflection mechanism is basically the same as the vertical deflection mechanism between the telescopic rod 300 and the base 100; the vertical deflection mechanism between the rotary joint 400 and the telescopic rod 300 includes an upper U-shaped joint 350 structured on the upper end of the telescopic rod 300, an upper matching joint part 410 structured on the lower end of the rotary joint 400, a connecting piece 500 inserted therebetween, and an anti-slip piece 600 and a spring 700 arranged on the connecting piece 500; the upper matching joint part 410 is located at the upper U-shaped joint 350, and ...

[0033] Compared with the prior art, the utility model has a simple and reasonable structure. The second hollow tube of the telescopic rod slides along the sleeve to retract into or extend out of the first hollow tube and is locked by the elastic buckle on the sleeve cooperating with the slot on the second hollow tube. In this way, the height of the lamp head can be conveniently adjusted to ensure the use effect of the magnifying glass lamp. At the same time, by rotating the lamp head 180° around the swivel joint, the telescopic rod is deflected 90° downward by the vertical deflection mechanism to lie on the upper surface of the base, and at the same time, the swivel joint is deflected 90° upward by the vertical deflection mechanism to make the lamp head and the base basically keep level. In this way, the folding and storage of the magnifying glass lamp is realized, and the volume of the magnifying glass lamp is greatly reduced, so that it is easy to carry or store.
