Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the light path element of a kind of adaptability laser range finder widely.
For achieving the above object, the utility model provides following technical scheme: a kind of light path element of laser range finder, comprise support, mainboard, optical mechanism, generating laser and laser pick-off plate, its medium-height trestle is fixed on mainboard, generating laser is arranged in optical mechanism, and described optical mechanism end is detachably provided with lens hanger, is embedded with reception eyeglass in described lens hanger, the both sides of described lens hanger are protruding with guidepost, and described optical mechanism is provided with the pilot hole suitable with described guidepost.
As preferably: the opposite side of the relative lens hanger of described optical mechanism is provided with embeded slot, described generating laser is arranged in optical mechanism by embeded slot, be fitted with elastic body in the cell wall of described embeded slot, described embeded slot run through the adjusting screw having and offset with generating laser.
As preferably: on described mainboard, indent has slot, described laser pick-off plate is interted by slot and described mainboard and arranges.
As preferably: described mainboard both sides are provided with several pilot holes, described support is fixed on mainboard by pilot hole, described support is made up of the support chip and the stay of bridge joint between support chip being fixed on mainboard both sides, and described optical mechanism is fixedly installed between mainboard and stay.
As preferably: described optical mechanism is provided with postive stop baffle, this postive stop baffle correspondence is arranged on directly over laser pick-off plate.
As shown from the above technical solution, the beneficial effect of this practicality is:
Compared to existing technology, by being provided with dismountable lens hanger on optical mechanism, make to receive eyeglass independent outside optical mechanism, not in the restriction by optical mechanism, the lens hanger of replaceable different reception eyeglass size can make optical mechanism adapt to far and near different range finding, effectively solve the limitation that laser range finder causes because of optical mechanism, adaptability widely, lens hanger and optical mechanism split-type design, also segment production process, improve production efficiency, lens hanger there is the setting with the suitable guidepost of the pilot hole of optical mechanism, namely dismounting is facilitated, the reception eyeglass on lens hanger can be made again corresponding with laser pick-off plate accurately, guarantee the precision of finding range.
Accompanying drawing explanation
Fig. 1 is the explosive view of the light path element of a kind of laser range finder of the utility model;
Fig. 2 is the front view of the light path element of a kind of laser range finder of the utility model;
Fig. 3 is the structural representation of optical mechanism in the light path element of a kind of laser range finder of the utility model.
Embodiment
Referring to figs. 1 through Fig. 3, the embodiment of the light path element of a kind of laser range finder of the utility model is described further.
A kind of light path element of laser range finder, comprise support 1, mainboard 2, optical mechanism 3, generating laser 4 and laser pick-off plate 5, its medium-height trestle 1 is fixed on mainboard 2, generating laser 4 is arranged in optical mechanism 3, optical mechanism 3 end is detachably provided with lens hanger 6, be embedded with in lens hanger 6 and receive eyeglass 7, the both sides of lens hanger 6 are protruding with guidepost 61, optical mechanism 3 is provided with the pilot hole 31 suitable with described guidepost 61, dismounting mode between optical mechanism 3 and lens hanger 6 is varied, it can be clamping, be spirally connected, bonding etc., preferably be spirally connected in order to ensure this practicality of stability between optical mechanism 3 and lens hanger 6 and thisly the most simply dismantle mode, not only facilitate the processing of parts but also facilitate the dismounting between all parts, the lens hanger that between optical mechanism 3 from lens hanger 6, split reassembling type designs replaceable different reception eyeglass size adapts to different distance and to find range distance requirement, increase substantially adaptability.
The opposite side of the relative lens hanger 6 of optical mechanism 3 is provided with embeded slot 32, generating laser 4 is arranged in optical mechanism 3 by embeded slot 32, elastic body 321 is fitted with in the cell wall of embeded slot 32, embeded slot 32 runs through the adjusting screw 322 having and offset with generating laser 4, by adjusting empty adjusting screw 322 to finely tune the position relationship of generating laser 4 to guarantee Laser emission accuracy, the limitation that in the same laser range finder of minimizing further, optical mechanism 3 causes because of mismachining tolerance.
On mainboard 2, indent has slot 21, laser pick-off plate 5 is arranged with mainboard 1 is interspersed by slot 21, owing to needing by being welded and fixed between laser pick-off plate 5 and mainboard 2, namely interspersed setting solves welding improves laser pick-off plate 5 position and electrical conductivity simultaneously stability without the problem supporting the welding difficulty caused.
