Abstract
The utility model relates to a magnifying lens for a geological survey, mainly aiming at solving the problem that burdened load in field is too large because a plurality of monomers are required to be carried when research personnel requires magnifying lenses with different multiples in the prior art. The magnifying lens for the geological survey is characterized in that a plurality of rectangular bulges are arranged on the edge of a lens, and the centerlines of the rectangular bulges are in parallel with the central axis of the lens; a lens holder consists of a lens mounting rack, a lens handle, a protective sleeve and a rotating shaft, the lens mounting rack and the protective sleeve are circular, the lens handle is fixed on the lens mounting rack and the lens mounting rack is connected with the protective sleeve through the rotating shaft; an annular groove is arranged at the central part of the lens mounting rack and is used for fixing the lens, and a plurality of rectangular guide rails are installed above the annular groove along the axial direction of the lens mounting rack; the dimension and the quantity of the rectangular guide rails are respectively matched with the dimension and the quantity of the rectangular bulges; and a limiting step is arranged in the annular groove. The magnifying lens for the geological survey has the advantages that the lens can be replaced by multiple lenses, the magnifying lens also has a lighting function and the burdened load of field survey personnel can be reduced.
Description
Technical field
The utility model relates to a kind of servicing unit that is used for geological mapping, specifically, relates to a kind of magnifier.
Background technology
Magnifier is the indispensable utensil that carries out geological mapping.Existing geological mapping aspect wearing quality, durability, has all obtained very big improvement after passing through scientific research personnel's improvement for many years with magnifier, still, aspect the applicability of magnifier, but changes very little.For example, when needing the magnifier of different accuracy and enlargement factor, the researchist just need carry a plurality of magnifieres.In a single day under lab, this situation can also overcome, but investigates operation in the open air, the weight of so a plurality of magnifieres often makes the researchist heavy unbearably, but but at one's wit's end.
Summary of the invention
In order to solve the problems of the prior art that background technology proposes, the utility model provides a kind of magnifier that is used for geological mapping of new structure, this kind magnifier can be changed a plurality of eyeglasses under the prerequisite of only using a mirror holder, and have illumination functions, have the mirror holder of saving and make resource, alleviate field study personnel heavy burden and characteristics easy to use.
The technical solution of the utility model is: this kind is used for the magnifier of geological mapping, comprises mirror holder and eyeglass, and its unique distinction is: there are some rectangular preiections in the edge of described eyeglass, and the center line of described rectangular preiection is parallel with the central axis of described eyeglass; Described mirror holder is made of eyeglass erecting frame, eyeglass handle, protective sleeve and rotation axis, described eyeglass erecting frame and protective sleeve are circle, described eyeglass handle is fixed on the eyeglass erecting frame, wherein, connects by rotation axis between described eyeglass erecting frame and the protective sleeve; The middle part of described eyeglass erecting frame has a ring groove and is used for fixing eyeglass, axially has some rectangular guidewaies along the eyeglass erecting frame above described ring groove; The size of described rectangular guideway and quantity match with the size and the quantity of described rectangular preiection, so that described rectangular preiection can fall into corresponding rectangular guideway simultaneously and glide; In described ring groove, corresponding every rectangular guideway has a limited step according to clockwise direction.
In addition, on the basis of such scheme, described protective sleeve can be adopted the structure of half cycle sealing, and for being implemented in the purpose of working under the darker condition of light, can make described eyeglass handle is hollow structure, it is built-in with the dc lighting device.
The utlity model has following beneficial effect: this kind magnifier can require to change arbitrarily eyeglass according to the user, therefore, when working, can only carry a mirror holder in the open air, carries eyeglass box then and gets final product.This kind of magnifier only utilizes a mirror holder, changes the prospecting requirement that just can realize behind the eyeglass the many multiples of rock, and the making resource of both having saved mirror holder has alleviated field work personnel's heavy burden again, is of very high actual application value.

Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with shown in Figure 2, this kind is used for the magnifier of geological mapping as Fig. 1, comprises mirror holder and eyeglass 7, and it is characterized in that: there are some rectangular preiections in the edge of described eyeglass 7, and the center line of described rectangular preiection is parallel with the central axis of described eyeglass; Described mirror holder is made of eyeglass erecting frame 6, eyeglass handle 5, protective sleeve 1 and rotation axis 2, described eyeglass erecting frame 6 and protective sleeve 1 are circle, described eyeglass handle 5 is fixed on the eyeglass erecting frame 6, wherein, connects by rotation axis 2 between described eyeglass erecting frame 6 and the protective sleeve 1; The middle part of described eyeglass erecting frame 6 has a ring groove 3 and is used for fixing eyeglass, above described ring groove along the some rectangular guidewaies 4 of axially having of eyeglass erecting frame; The size of described rectangular guideway 4 and quantity match with the size and the quantity of described rectangular preiection, so that described rectangular preiection can fall into corresponding rectangular guideway simultaneously and glide; In described ring groove 3, corresponding every rectangular guideway has a limited step according to clockwise direction.
For improving the water proofing property of protective sleeve, described protective sleeve 1 can be adopted the structure of half cycle sealing, its structure is as shown in Figure 3.
In addition, consider operation in the open air, run into the situation of insufficient light through regular meeting, therefore, described eyeglass handle 5 can be designed to hollow structure, it is built-in with dc lighting device 8, and its structural representation as shown in Figure 4.Like this, in case when needs throw light on, lighting device can be opened, can improve this kind magnifier application efficiency under special circumstances greatly.This kind of magnifier is when changing eyeglass, and only need rotate eyeglass in the counterclockwise direction can screw out ring groove with eyeglass, when being threaded to corresponding rectangular guideway position, can take out carrying on the eyeglass.
