Description

Height adjusting device and illuminating lamp Technical Field The utility model relates to the technical field of lamps, in particular to a height adjusting device and an illuminating lamp. Background In the field of eye-protection lighting equipment, in particular to vertical street lamp products, the realization of flexible adjustment of the height of a lamp cap to meet the lighting requirements of different use scenes (such as reading, working and leisure) is an important function. Traditional eye-protection street lamp adopts mechanical lifting structure to realize the altitude mixture control generally. Such arrangements typically rely on complex gear mechanisms in combination with screw locking arrangements. However, this conventional lifting solution has significant drawbacks. The key problems are that the complexity and the huge volume of the lifting structure lead to complex operation, large space occupation and limited adaptability. In particular, complex gear set members themselves occupy a large physical space, while the interior space of a supporting pole of a street lamp is often limited and elongated, which makes installation and layout of the gear drive difficult and cumbersome, increasing the complexity of the product interior design and assembly difficulties. More importantly, when the user needs to adjust the height of the lamp cap according to the actual use situation (for example, switching from desktop work to standing activity), an additional special tool (such as a screwdriver or a wrench) is needed to unscrew the fixed screw, operate the gear mechanism to lift, and re-screw the screw to fix after reaching the target height. The series of operation steps are tedious and time-consuming, are extremely inconvenient for users, and greatly reduce the usability and user experience of the product. Meanwhile, the dependence on tools means that the height adjustment cannot be completed at any time, quickly and freehand, so that the instant adaptability and flexibility of products in different application scenes are greatly limited, and therefore, the height adjustment device and the illuminating lamp are provided for solving the problems.
