Yet at use clamping device 122 clamping catoptrons 116,118, with 120, the difficulty that anchor clamps 126 shown elastic force are assembled for catoptron is very important with the assembling quality.Excessive elastic force can increase the degree of difficulty of catoptron assembling; Too small elastic force then is difficult for the position of stationary mirror, can cause the deviation of light path; Therefore, to provide suitable elastic force for catoptron be very important to anchor clamps 126.

(3) utility model content

A purpose of the present utility model provides a kind of clamping device that is applied in the carrier, can provide different elastic force to gripped object.

Another purpose of the present utility model is to provide a kind of clamping device that is applied to bearing lens, has good fixed effect after can making the elastic force that is provided make things convenient for eyeglass to install and install.

According to above-described purpose, the utility model provides a kind of clamping device that is fixed in the carrier, it comprises a bearing seat and anchor clamps, an one breasting face of bearing seat and a front of anchor clamps are towards an eyeglass, both cooperate in order to fixing len, it is characterized in that: anchor clamps have a back side of a variation in thickness, and wherein the thickness of a fixed part at the back side is greater than the thickness of a non-fixed portions at the back side, make the elastic force of fixed part greater than the elastic force of non-fixed portions.

For further specifying the purpose of this utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.

(5) embodiment

When the utility model was described in detail with following embodiment, the personage who is familiar with this field will be appreciated that and allow to have some corrections and replacement under the situation that does not break away from spirit of the present utility model.The structure that is disclosed is not limited to the carrier clamping device of special-purpose, accompanying drawings only be preferred embodiment of the present utility model, and be not in a limitative way the utility model scope.

The utility model provides an a kind of eyeglass clamping device that is fixed in a bottom surface of a carrier, the eyeglass clamping device has a bearing seat and anchor clamps, one breasting face of breasting face contacts with one first face portion of an eyeglass, anchor clamps have a positive and back side, wherein the front contacts with one second face portion of eyeglass, parallel second of first of eyeglass, be characterized in: the back side of anchor clamps and the thickness between the front are thick away from bottom surface portions than anchor clamps near bottom surface portions at anchor clamps, make anchor clamps extremely have force variation away from bottom surface portions near bottom surface portions.

The configuration diagram of carrier clamping device of the present utility model and carrier as shown in Figure 3, the part assemblies in the carrier 10 comprise some

catoptrons

16,18, with 20, lens subassembly 14 and CCD camera assembly 12; Wherein, clamping device 22 is in order to the

rectangular mirror

16,18 that fixedly has thickness, with 20.Clamping device 22 then comprises bearing seat 24 and anchor clamps 26 at least.

Figure 4 shows that side schematic view according to Fig. 3 clamping device of the present utility model.Bearing seat 24 has a breasting face 33 in order to the carrying catoptron, and it contacts with the back portion of catoptron; Breasting face 33 is generally an inclined-plane on bearing seat 24, and in order to carry the needs of catoptron, breasting face 33 can be complete tabular surface, or has the inclined-plane of a support salient point 28, utilizes the back side of the catoptron that supports salient point 28 contact portions.In addition, bearing seat 24 has a bottom surface 30 and is fixed in carrier bottom 32; And bearing seat 24 is general and carrier while direct forming forms.

One of characteristics of the present utility model are that anchor clamps 26 are one to have the structure of different-thickness design.As shown in Figure 4, anchor clamps 26 1 ends are fixed on the carrier bottom 32, extend to the other end along the direction of almost parallel breasting face 33; The front 34 of anchor clamps 26 is the front in the face of catoptron, utilizes the design shape in front 34 to contact with the front portion of catoptron; And the back side 36 has thicker structure near the part that is fixed in carrier bottom 32.And away from the part that is fixed in carrier bottom 32, the back side 36 of anchor clamps 26 has thin structure (thickness); The material of anchor clamps 26, by the material that elastic force can be provided, just sheet for example maybe can produce deformation and produces the material of elastic force, and for example the rubber-like plastic cement material is made.In addition, the variation in thickness of anchor clamps can be gradual continuous variation (as level and smooth ramped shaped), or gradual phase change (as stepped).Such clamp structure, itself can provide different force variation because of thick, thin structure; Thicker structure provides bigger elastic force, and thin structure provides less elastic force, makes that like this catoptron is easy to install, and takes into account catoptron simultaneously the fixing effect in back is installed.The thickness structure at the back side 36 of anchor clamps 26 of the present utility model changes, and can be gradual continuously, can also be interim, than thickness portion, extends to the thin part of another minute stiff end by stiff end, and the elastic force of multistage is provided.In addition, the forming mode of anchor clamps of the present utility model, can come to be shaped with the carrier branch and assemble (when for example the material of anchor clamps is firm sheet) again, or be shaped together (when for example anchor clamps material and carrier are identical) with carrier, utilize the shaping fixtures such as mould of different-thickness design can finish anchor clamps of the present utility model and make.

The above is preferred embodiment of the present utility model only, is not in order to limit claim of the present utility model; All other do not break away from that equivalence that spirit that the utility model discloses finishes changes or equivalence is replaced, and all should be included in the patent protection scope of the present utility model.
