The LED light level bubble 130 is disposed on one outer surface of the body 110 and extends at least to two opposing surfaces, i.e., the LED light level bubble 130 extends at least on three surfaces of the level 100, whereby an engineer can view the tilt angle while standing on different sides of the level 100 during a measurement.

In the embodiment of fig. 2-3, LED level bubble 130 is located at an upper edge of level 100 and extends over an upper surface of level 100 and two opposing surfaces in the thickness direction. In other embodiments, LED level bubble 130 may alternatively, or additionally, be disposed on the left and right edges of level 100.

The LED horizontal bubble 130 is preferably provided to a middle position on the upper edge of the body 110.

The LED horizontal bulb 130 according to the present invention is essentially a LED display screen, which is not a conventional LED bulb. According to the utility model discloses a LED level bubble 130 is constructed and can light corresponding bulb according to the size at inclination. In one embodiment, when the left position of the platform on which level 100 is placed is higher than the right position (case A), the left portion of LED level bubble 130 is highlighted; similarly, when the right position is higher than the left position (case B), the right portion of the LED horizontal bubble 130 is highlighted. Alternatively, in case of the platform being case A, the right portion of the LED horizontal bubble 130 is highlighted; similarly, when the platform is condition B, the left portion of the LED horizontal bubble 130 is highlighted.

According to the present invention, the LED horizontal bubble 130, in the embodiment shown in fig. 2 and 3, has a plurality of display bars 131 alternately arranged along the length direction of the body 110; in another embodiment, not shown, the LED horizontal bubble 130 has a display bar 131 that extends continuously along the length of the body 110. The display bar 131 may be provided with a scale indicating the tilt angle.

According to the LED horizontal bubble 130 of fig. 2-3, after the angle sensor measures the inclination data, the LED horizontal bubble 130 may be set to be lighted only on the display bar 131 corresponding to the inclination data; or may be set to 0 degrees to be highlighted on all the display bars 131 corresponding to the inclination data. Preferably, the LED level bubble 130 according to the present invention is configured to include a plurality of display bars 131 as shown in fig. 2 and 3, so that when the placement position of the level 100 and the eye position of the engineer have a large distance in the vertical direction, the engineer can roughly calculate the rough inclination angle of the platform by counting the positions of the display bars 131 with the maximum brightness.

According to a preferred embodiment of the present invention, the lower end position of the level 100 can be provided with a scale 112 for measuring the length, and the level 100 thus has the function of a measuring tape.

The level 100 may be provided with elongated through holes 111 at both ends in the longitudinal direction. The elongated through hole 111 has a stopper 111A protruding in a direction away from the body 110 at a middle portion of the elongated through hole in a length direction thereof. When not in use, the engineer can hang the level 100 on the hook by using the limiting opening 111A of the through hole 111.

Preferably, the spacing port 111A is formed in a semicircular shape, and the center of the spacing port 111A is coaxial with the longitudinal center line of the level 100. When level 100 is hung on the hook, level 100 is self-standing vertically.

Alternatively, the through-hole 111 shown in fig. 2 to 3 is provided as a triangular through-hole having a vertex angle toward both ends of the body 110 in the length direction

The outer surface of the LED horizontal bubble 130 is formed in a cylindrical shape. Specifically, in one embodiment, the cross section of the LED horizontal bubble 130 is in the shape of an isosceles trapezoid, wherein the top surface of the isosceles trapezoid corresponds to the upper end surface of the body 110; in another embodiment, the cross-section of the LED horizontal bubble 130 is rectangular.

The LED level bubble 130 of the present invention is preferably configured to be recessed inwardly from the outer surface of the body 110. In the event that level 100 is accidentally dropped, the likelihood of LED level bubble 130 hitting the outside world directly is greatly reduced. Similarly, the display screen of the angular digital indicator 120 is also provided in the form of a recess, compared to other positions of the surface of the body 110.

Referring to fig. 2, a first buffer 140 is preferably provided at a position where the upper end surface of the body 110 is connected to the LED horizontal bubble 130. The first buffer 140 may be a member made of foam or plastic. Further, optionally, second bumpers 150 of similar action and material may also be provided at both lengthwise ends of the level 100.

More preferably, the through-hole 111 for being engaged with the external hook is provided in the second buffer member 150. The second cushion 150 is detachably fixed to the body 110 of the level 100. In one embodiment, a cover plate for closing the inner space of the body 110 and corresponding fasteners, such as screws, are provided at both ends of the body 110 in the length direction. After the second cushion member 150 is fixed to the body 110, the second cushion member 150 just covers the fastening member and the cover plate.

The second cushion member 150 extends to both ends in the height direction of the level 100. The second buffer 150 is provided with a groove 151 for alleviating an external impact action at a corner corresponding to the body 110. It can be understood that the second buffer 150 is easily deformed at the position where the groove 151 is provided. The second buffer of the above-described form allows level 100 to achieve a longer buffer distance during impact when level 100 is dropped and the corner first touches the ground, in which case level 100 is less likely to be damaged.

A vertical liquid level bubble may also be provided on the body 110 between the through hole 111 and the angle digital indicator 120 in the length direction of the level 100. The body 110 is provided with a partition 113 made of a transparent material on an outer surface corresponding to the vertical liquid level bubble, thereby protecting the vertical liquid level bubble inside thereof. The transparent material may be selected from rigid plastics, glass, and the like.

With further reference to FIG. 2, the outer edge of level 100 is recessed from the outer periphery inwardly to form an annular protrusion 160 at the outer edge, which will facilitate the ability of an engineer to grasp level 100.
