Description
Technical field
The present invention relates to a kind of single prism group, belong to optical detection apparatus technical field.
Background technology
At present, in high-precision coordinate measurement or range observation field, single prism group is widely used, and after finding measurement point accurately, single prism group requires to be permanently fixed conventionally, can not realize left and right translation, makes troubles to the accurate rapid alignment prism of staff.In addition, single prism group of the prior art does not possess rainproof function, and at rainy weather, rainwater drenches prism assemblies, easily causes testing result inaccurate.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of single prism group is provided, solve single prism group in prior art and finely tune and cause prism alignment to adjust inconvenient technical matters about cannot realizing.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of single prism group, comprises pedestal, support and prism assemblies; Described prism assemblies comprises prism frame and be flush-mounted in the prism in prism frame, and described prism frame and prism are coaxially set; On described pedestal, be connected with horizontal table, on described horizontal table, be equipped with horizontal slide rail, corresponding with the horizontal slide rail sliding-rail groove that offers on described support; On described horizontal table, be also provided with the leading screw be arrangeding in parallel with horizontal slide rail, leading screw runs through support and is threaded with described support, and one end of leading screw is also connected with knob.
As a further improvement on the present invention, the rear casing that described prism frame comprises front shroud and is threaded with front shroud, the front end of described prism is supported on the inner side of front shroud by elastic washer, and rear end is flush-mounted in rear casing.
As a further improvement on the present invention, the front end of described front shroud is provided with the rainproof convex edge of extending forward.
As a further improvement on the present invention, the junction of described front shroud and rear casing is provided with rainproof O-ring seal.The setting of rainproof O-ring seal prevents that rainwater from infiltrating in front shroud and rear casing, avoids polluting fuzzy prism.
As a further improvement on the present invention, on described prism frame, be also connected with and instruct the aiming at alignment prism center to observe board.
As preferred version of the present invention, described aiming is observed board and is made up of fluorescent material.
Compared with prior art, the beneficial effect that the present invention reaches is: 1, can the in the situation that of mobile foundation not, realize prism assemblies and move left and right, play auxiliary object of aiming at fine setting, be convenient to search directed prism in site operation, improve prism detection efficiency; 2, adopt leading screw adjustment structure, have the advantages that degree of regulation is high; 3, be provided with rainproof convex edge, even if still can ensure accurate, the clear feedback of light path at rainy weather, improve accuracy of detection; 4, installed to aim at and observe board, and aimed at and observe board and be made up of fluorescent material, under the working environment of insufficient light, staff still can observe board rapid alignment prism according to aiming.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of prism assemblies of the present invention.
In figure: 1, pedestal; 2, support; 3, prism frame; 3a, front shroud; 3a-1, rainproof convex edge; 3b, rear casing; 3c, elastic washer; 4, prism; 5, horizontal table; 6, horizontal slide rail; 7, leading screw; 8, knob; 9, aim at and observe board; 10, rainproof O-ring seal.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, single prism group, comprises pedestal 1, support 2 and prism assemblies; Prism assemblies comprises prism frame 3 and is flush-mounted in the prism 4 in prism frame 3, and prism frame 3 is coaxially set with prism 4; On pedestal 1, be connected with horizontal table 5, on horizontal table 5, be equipped with horizontal slide rail 6, corresponding with horizontal slide rail 6 sliding-rail groove that offers on support 2; The two ends of leading screw 7 are by bearings on horizontal table 5, and leading screw 7 is arranged in parallel with horizontal slide rail 6, and leading screw 7 runs through support 2 and is threaded with support 2, and one end of leading screw 7 is also connected with knob 8.On prism frame 3, be also connected with and instruct the aiming at alignment prism 4 centers to observe board 9; aiming is observed on board 9 and is drawn and have taking white as background colour; guiding pattern taking redness as guiding arrow color; because single prism group can be operated under the environment of insufficient light often; for the ease of staff's rapid alignment prism 4, aiming is observed board 9 and is adopted fluorescent material to make.
As shown in Figure 2, for the structural representation of prism assemblies of the present invention, the rear casing 3b that prism frame 3 comprises front shroud 3a and is threaded with front shroud 3a, the front end of prism 4 is supported on the inner side of front shroud 3a by elastic washer 3c, rear end is flush-mounted in rear casing 3b, elastic washer 3c is mainly used in installing fixed prism 4, plays buffer action simultaneously, avoids external force collision to cause prism 4 to damage.Photoelectric Detection work can run into rainy weather conventionally; if prism assemblies is drenched by rainwater; particularly on prism 4 reflective surfaces, speckle with rainwater; will affect the reflection of light path, cause detection accurately on the low side, therefore; the present invention is provided with the rainproof convex edge 3a-1 extending forward at the front end of front shroud 3a; the junction of front shroud 3a and rear casing 3b is provided with rainproof O-ring seal 10, and the setting of rainproof O-ring seal 10 prevents that rainwater from infiltrating in front shroud 3a and rear casing 3b, avoids polluting fuzzy prism 4.
When the present invention works, clockwise or be rotated counterclockwise knob 8, the left and right translation of prism assemblies can be realized, the left and right translation of prism assemblies can be the in the situation that of mobile foundation not 1, realized, reach the object of auxiliary fine setting, be convenient to staff and quick and precisely find prism 4 accurately.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
