Light-emitting drawing pin assembly

Abstract

The invention discloses a light-emitting drawing pin assembly, relates to the field of drawing pin structures, in particular to an improvement on the structure of a light-emitting drawing pin and provides the light-emitting drawing pin assembly which is exquisite in structure, convenient to use, good in stability and extremely good in use effect. An LED lamp is arranged in the drawing pin. A base is made of a cork board and is installed on the wall. An aluminum plate is arranged in the base, and a battery and a switch which communicate with the aluminum plate are further arranged below the base. A square groove used for containing the aluminum plate is formed in the side, facing the wall, of the base, the aluminum plate is parallel to the base, and the edge of the aluminum plate is fixedly connected to the groove wall of the square groove. A clearance is reserved between the aluminum plate and the groove bottom of the square groove, and a clearance is reserved between the aluminum plate and the wall. The structure is exquisite, use is convenient, stability is good, and the use effect is extremely good.

Description

technical field [0001] The invention relates to the field of pushpin structures, in particular to an improvement of the structure of a luminous pushpin. Background technique [0002] Thumbtacks are one of the commonly used stationery items in daily life. They are used to pin photos in the window for people to watch. At present, in order to improve the viewing effect of photos, the National Bureau announced a document called "A kind of LED thumbtack", the Chinese utility model patent with the application number "201220324022.X", proposed a base composed of cork board and aluminum board and a pushpin composed of connected LED lights and needles; however , People find that it has the following defects in actual use: 1. Since the aluminum plate is located inside the cork plate, it is impossible to judge whether the thumbtack is in contact with the aluminum plate.

[0002] Thumbtacks are one of the commonly used stationery items in daily life. They are used to pin photos in the window for people to watch. At present, in order to improve the viewing effect of photos, the National Bureau announced a document called "A kind of LED thumbtack", the Chinese utility model patent with the application number "201220324022.X", proposed a base composed of cork board and aluminum board and a pushpin composed of connected LED lights and needles; however , People find that it has the following defects in actual use: 1. Since the aluminum plate is located inside the cork plate, it is impossible to judge whether the thumbtack is in contact with the aluminum plate. The lamp cannot be turned on, which is extremely inconvenient to use; 2. Since the needle is a conductor with resistance, and the cork board is an insulator, when more thumbtacks are inserted, the cork seat is likely to heat up greatly, thereby affecting its own structural quality. And bring certain potential safety hazards; 3. Since the aluminum plate in the cork board has no contact with the outside world, when the LED light does not emit light, the user cannot judge whether the aluminum plate is faulty or the thumbtack is faulty, which greatly increases the difficulty of operation.
