Description

Level Auxiliary Light

technical field

The utility model relates to an auxiliary lighting lamp for a level gauge, which is a lighting tool suitable for assisting level gauge measurement under the condition of bad light conditions.

Background technique

A measuring instrument such as an ordinary level is an instrument that measures the height difference between two points by establishing a horizontal line of sight with the naked eye. The main components of a conventional level include a telescope, a tube level (or compensator), a vertical axis, a base, and a foot screw. According to the structure, it is divided into micro-tilt level, automatic leveling level, laser level and digital level (also known as electronic level). According to the accuracy, it can be divided into precision level and ordinary level. These levels can complete some routine measurement tasks, but it is difficult for ordinary levels to complete measurement tasks in dark basements or in the middle of tunnels, or when measurements must be made during periods of poor light in order to speed up the progress of the project.

Due to the rapid development of subways and tunnels, there are more and more cases where underground construction is required. Due to the dark underground light, when using a level to determine the height of the ground, the reading on the scale is often unclear through the eyepiece. Usually, a The staff stand beside the scale to take readings, occupying personnel, and the operation efficiency is low, which is not conducive to the efficient and rapid construction.

In many cases, due to the needs of the construction period or urban control, construction needs to be carried out at night, the construction site is large, and the light intensity is not enough to clearly identify the scale line on the level scale. Usually, two operators are required on the construction site. To complete the use of the level gauge, a staff member is required to read close to the scale, which causes a waste of human resources and is not conducive to the rational distribution of the work intensity of the staff.

Utility model content

In order to solve the above-mentioned problems, the utility model discloses an auxiliary lighting lamp for the level gauge. The auxiliary lighting lamp is fixed on the level gauge, emits parallel light, and irradiates the scale to help the operator who uses the level gauge use the level gauge. Being able to clearly see the reading on the scale does not require a staff member to take a special reading, which reduces unnecessary human resource occupation and improves the work efficiency of the entire team.

Auxiliary lighting for the level, including a lamp housing and a support clamp, the lamp housing and the support clamp are connected through a flexible metal bellows, the light-emitting side of the lamp housing is a transparent partition, and a light bulb and a concave mirror are arranged inside the lamp housing. The concave side of the concave mirror faces the bulb and the transparent spacer.

The bulb is installed on the lamp holder, the bulb is flush with the central horizontal line of the concave mirror, and the lamp holder is fixed in the lamp housing through the bracket.

One end of the bracket is fixed to the lamp holder, and the other end is fixed to the edge of the concave mirror. A light baffle is arranged on the side of the bracket facing the light bulb. The outer periphery of the light baffle is fixed to the surroundings of the concave mirror. There is a gap between them.

A wire is arranged inside the flexible metal bellows, one end of the wire is connected to the lamp holder, and the other end of the wire is connected to the battery arranged in the support clip, and the support clip is provided with a charging plug for charging the battery.

The electric wires are fixed in close contact with the inner wall of the lamp housing in the lamp housing, and the wires are connected to the lamp holder from between the light shield and the bracket, and a switch for cutting off and connecting the wires is arranged on the lamp housing.

Several slidable fixing clips are arranged on the flexible metal bellows.

The inner surface of the support clip is provided with anti-slip pads.

The working principle of the utility model is:

The support clamp is clamped on the tripod, the flexible metal bellows has a certain supporting force, and the lamp housing can be lifted in the air, and the light emitted by the bulb is irradiated to the concave mirror or reflected to the concave mirror through the light baffle plate, and the concave mirror transmits the light to the concave mirror. Gathered together, a parallel light is emitted from the center of the concave mirror, and the parallel light is emitted from the gap in the inner circumference of the light barrier, and the position of the lamp housing is adjusted so that the parallel light shines on the scale of the level to increase the light at the scale of the level brightness.

The beneficial effects of the utility model:

Fix the utility model on the tripod by clamping the support clamp, adjust the position of the lamp housing through the flexible metal bellows, adjust the parallel light emitted from the lamp housing to the scale, and improve the brightness around the scale, which can realize Allow the operator of the level to see the reading on the scale clearly. In an environment with weak light, he can read by himself and complete the use of the level by himself. By adjusting the shaping clips, the supporting capacity of the flexible metal bellows can be changed, and the distance between two adjacent shaping clips can be reduced. The resistance to deformation of the flexible metal bellows between the two shaping clips can be improved, which helps the lamp housing after positioning. , so that the flexible metal bellows can support the lamp housing and keep the position unchanged.
