Description

Distance measuring instrument

Technical Field

The utility model relates to a measuring equipment's technical field, more specifically say, it relates to a distancer.

Background

The distance meter is a tool for measuring distance, and the distance meter in the prior art is divided into an ultrasonic distance meter, an infrared distance meter and a laser distance meter, wherein the most commonly used distance meter is the infrared distance meter and the laser distance meter. The infrared distance meter measures distance by using a non-diffusion principle during infrared ray transmission, when the infrared distance meter is used, infrared rays are sent out from the distance meter, touch a reflector and are reflected back to be received by the distance meter, and then the distance can be calculated according to the time from sending to receiving of the infrared rays and the transmission speed of the infrared rays; the laser range finder is an instrument for measuring the distance to a target by using a certain parameter of modulated laser, and is divided into a phase range finder and a pulse range finder according to a range finding method, wherein the pulse laser range finder emits a pulse laser beam or a sequence of short pulse laser beams to the target when in work, a photoelectric element receives the laser beam reflected by the target, and a timer measures the time from the emission to the reception of the laser beam and calculates the distance from an observer to the target. The phase-method laser range finder detects a distance by detecting a phase difference occurring when emitted light and reflected light propagate in a space.

A distance meter is disclosed in chinese patent publication No. CN 209246984U. The side surface of one side of the machine shell is provided with a threaded hole, the side surface of the machine shell, which is provided with the threaded hole, is provided with a mounting groove, the bottom wall of the mounting groove is provided with a yielding groove, and the threaded hole is formed in the bottom wall of the yielding groove; a sealing plate is arranged in the mounting groove, a sealing ring extending into the abdicating groove is arranged on the side surface of the sealing plate close to the abdicating groove, and an elastic sealing gasket abutting against the inner side wall of the abdicating groove is arranged on the outer side wall of the sealing ring along the circumferential direction; the side that the casing was equipped with the mounting groove still is equipped with gets the thing groove, gets on the thing groove extends to the inside wall of mounting groove. The connecting wire is located first wire casing, and the closing plate is located the mounting groove, and the magnetism spare is inhaled the annex with first mutually and is inhaled, and the sealing ring is located the inslot of stepping down, and elastic sealing pad offsets with the inside wall and the spacing ring in the groove of stepping down to the groove of stepping down is sealed firmly, can prevent to take off the condition emergence that the back screw hole advanced grey, intake or various impurity are stayed to the distancer from the A-frame. When needing to use the distancer (when needing to install the distancer on the A-frame promptly), through getting the thing groove with the closing plate dial out in the mounting groove can. After the sealing plate is pulled out from the mounting groove, the sealing plate can be contained in the containing groove. When the sealing plate is accommodated in the accommodating groove, the sealing ring of the sealing plate is clamped towards the groove. After the sealing plate is accommodated in the accommodating groove, the magnetic part and the second adsorption part are attracted. After the use of distancer (being about to the distancer follow A-frame back of pulling down), dial out the closing plate from holding the inslot through getting the thing breach, then aim at the sealing ring on the closing plate recess card can again.

Screw shutoff or the rusty condition can be solved through the mounting groove that sets up in above-mentioned scheme, but does not use for a long time to the observation head, influences observation effect such as easy ash falling.
