Description

TECHNICAL FIELD

[0001] The utility model relates to lighting equipment technical field, specifically, it is a pen lamp with rotatable pen clip of damping. BACKGROUND

[0002] In the field of lighting technology, products are developing towards miniaturization and lightness. The pen lamp is provided with a bulb or a light emitting device at one end for illumination, has the characteristics of portability, small size, easy operation, etc., is small in structure, convenient to use, and is widely used in automobile maintenance, medical examination and detection, home standby lighting, outdoor sports light and various application scenarios.

[0003] Traditional pen clips usually have a simple structure and can achieve basic fixing functions, but have some limitations in use. Most traditional pen clips only support single-direction fixing, which limits the flexibility of users in different angles and positions. Secondly, traditional pen clips often lack damping mechanism when rotating, which may cause the pen to be unable to be stably kept after rotating to a certain position, affecting actual operation. The conventional pen clips on the market are divided into two structural forms:

[0004] One is a non-rotatable pen clip, i.e., the pen clip cannot rotate with the shell, and the main body cannot be rotated after the product is fixed by the pen clip. The other is a rotatable pen clip structure, and the pen clip and the main body often adopt a circular arc interference fit. When the user rotates the pen clip, the pen clip and the main body produce scraping, and after a long period of use, not only the rotation force value of the pen clip decreases, but also the rotating area is worn and has debris. Patent No. CN201922494505.9 discloses a pen lamp with a rotatable pen clip by magnetic attraction. The friction force of the pen clip when rotating is mainly provided by the first protruding part of the pen clip and the main body. When rotating, due to the friction effect, the pen clip can be rotated and fixed at any angle. The pen clip structure of this scheme makes the pen clip and the main body achieve the functions of damping effect and arbitrary angle rotation and stopping. However, such structure will cause wear and tear between the pen clip and the main body during relative rotation, damage the appearance, and the rotation feel will also decrease over time. In addition, patent No. CN201710037733.6 discloses another rotating pen clip installation structure, but the pen clip is fixed by the front and rear shells, and the pen clip can only rotate in the opening area and cannot be rotated at 360 degrees.
