Description

Technical Field

[0001] The utility model relates to a level ruler, in particular to a two-way window level ruler with an LED light source for enhancing vision. Background Art

[0002] As a conventional measuring tool, the spirit level has multiple measuring methods such as horizontal and vertical, and is widely used in the fields of construction, mechanical installation, and carpentry. When measuring vertical surfaces, the traditional spirit level can only observe the spirit level from the side, which is very inconvenient. In order to be able to observe the spirit level from the front when measuring vertical surfaces, a spirit level with a 90° spirit level and a two-way window has appeared on the market. A 45° inclined reflector is used to reflect the 90° spirit level to the top surface of the spirit level, and the measurement is observed through the top window. Its main structure and principle are basically the same. Due to the use of a reflector for reflection, the spirit level image in the reflector needs to pass through a narrow cavity to the observation window on the top surface of the spirit level. Since the natural light from the outside cannot illuminate the reflector and the cavity. The image of the spirit level observed by the human eye through the window is dim. In particular, the image is more blurred in a dimly lit indoor environment, which brings limitations to its use and promotion.

[0003] After investigation, the existing Chinese patent number CN201520424789.3, "A Vertical Two-way Window Level Ruler", includes a support, in which a level bubble, a lens and a transparent window are fixed, the level bubble, the lens and the transparent window are triangular in the support, and the image of the level bubble is refracted to the transparent window through the lens, and the support is sealed by setting a support cover. The utility model uses a lens and a transparent plate, so that the lens reflects the bubble to the front, and the position of the bubble in the lens can be seen through the transparent window, so that the measurement personnel can directly observe the position of the bubble from the front.

[0004] There is also a Chinese patent with patent number CN202223105469.0, "A two-way window level ruler", which includes a ruler body, a mirror base, a level bubble and two round seat cover plates, the round seat cover plates are fixed on both sides of the level bubble, and a round seat hole for installing the level bubble is opened on the ruler body. Buckles matching the round seat holes are provided on the left and right sides of the round seat cover plate, and the round seat cover plate is fixed to the ruler body by buckling. Arc grooves matching and connected with the two round seat cover plates are concave on the right sides of the front and back sides of the mirror base. The mirror base is inserted into the ruler body and buckled with the round seat cover plates by buckling. An intermediate buckle is provided in the middle of the arc groove of the mirror base and buckled with the round seat hole. A reflector is installed on the left side of the mirror base to the right and downward, and a magnifying transparent sheet is installed on the upper end of the mirror base. A corresponding two-way window hole is opened on the upper end face of the ruler body.
