Abstract
The utility model discloses a handheld observation target device which comprises glass of which the periphery is inlaid with a frame, wherein a lamp is arranged on the rear of the glass; the lamp is arranged on a lamp holder fixed on the frame; a vertical black line is marked at a center line position on the front side of the glass. According to the handheld observation target device disclosed by the utility model, the illumination problem during measurement of an underground engineer transit is solved, a flashlight, a fine steel chisel, white paper or other materials are not needed to be held by the survey crew, the device is small in size, light in weight and convenient to carry, and the labor intensity of the survey crew in a severe underground cavern environment is reduced. The handheld observation target device is sufficient in illumination and uniform and clear in brightness, the operation of an instrument observer is promoted, the instrument observer easily finds an observation object, the observation object can be rapidly aligned, and the measurement speed is obviously increased.
Description
Technical field
The utility model relates to surveyor's beacon, particularly a kind of hand-held survey signal device.
Background technology
Underground works is usually insufficient because throwing light on, while using optical instrument to measure, running into greatest problem is insufficient light, gauger cannot see measurement target clearly, and particularly target is often a tiny drill rod when shaft centerline measurement, and when measurement, optical instrument is often because of the not enough position that is difficult to accurately measure axis of illumination.When at present underground engineering survey, survey crew often wants hand-held torch to increase brightness of illumination, or puts a blank sheet of paper after thin drill rod, irradiates blank sheet of paper with torch.Often because of electric torch shine inclined to one side, or because of electric torch brightness irregularities, or because blank sheet of paper is too soft, got wet, can not form good background, bring larger difficulty to Instrument observation person.Cause measuring speed slow, the problem that measuring accuracy is not high.
Utility model content
For overcoming the shortcomings and deficiencies of above-mentioned prior art, the utility model proposes a kind of hand-held survey signal device.
Scheme of the present utility model is:
A kind of hand-held survey signal device, comprises that a periphery studs with the glass of frame, is provided with a light fixture after described glass, and described lamp installation is on a lamp bracket being fixed on frame, and the midline position of described glass front is marked with a vertical black line.
Preferably, described vertical black line bottom extends to glass edge edge, and the frame at this place forms v-notch.
Preferably, described glass is inverted trapezoidal.
Preferably, described light fixture surrounding is provided with reflection shield, and light fixture also comprises the lamp switch that is arranged on reflection shield outside.
Further preferred, on the frame of described glass top, be also provided with one handle.
Compared with prior art, the beneficial effects of the utility model have:
(1) hand-held survey signal device described in the utility model, lighting problem while having solved underground works transit survey, survey crew does not need the materials such as hand-held torch, thin drill rod, blank sheet of paper, this device volume is little, lightweight, easy to carry, reduce the labour intensity under survey crew underground chamber rugged surroundings;
(2) the utility model sufficiency of illumination, and brightness is even, clear, is conducive to apparatus measures personnel operation, and Instrument observation person is easy to find observed object, and can aim at very soon observed object, has obviously accelerated measuring speed.
Accompanying drawing explanation
Fig. 1 is the structural representation of hand-held survey signal device described in the utility model;
Embodiment
Understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the hand-held survey signal device that the utility model discloses, comprise that a periphery studs with the glass 1 of aluminum alloy frame 2, described glass 1 adopts the frosted tempered glass that is inverted trapezoidal, the described chargeable light fixture 3 that is provided with below, described lamp installation is on an aluminium alloy lamp bracket 4 being fixed on aluminum alloy frame, the midline position of described glass front is marked with a vertical black line, vertically black line bottom extends to glass edge edge, the aluminum alloy frame at this place forms v-notch, does not block survey mark black line.On the frame of described glass top, be also provided with one handle 5, be convenient for carrying.
In addition, described light fixture surrounding is provided with reflection shield, and light fixture also comprises the lamp switch that is arranged on reflection shield outside.
When measurement if by this device just facing to surveying instrument, open switch, can clear display measurement mark, under Instrument observation person commander, move left and right this device, can accurately determine the position of survey line.Lighting problem when this device has solved underground engineering survey well, has simplified running program, has improved measuring accuracy and efficiency, has reduced labour intensity.
Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
Claims (5)
1. a hand-held survey signal device, it is characterized in that: comprise that a periphery studs with the glass of frame, after described glass, be provided with a light fixture, described lamp installation is on a lamp bracket being fixed on frame, and the midline position of described glass front is marked with a vertical black line.
2. hand-held survey signal device according to claim 1, is characterized in that: described vertical black line bottom extends to glass edge edge, and the frame at this place forms v-notch.
