Embodiment

In order to make the juror can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Fig. 1 is the decomposing schematic representation of camera lens of the present utility model and buffer structure, and Fig. 2 is the schematic perspective view of buffer structure of the present utility model, and Fig. 3 is the partial sectional view of camera lens of the present utility model and buffer structure.The buffer structure 2 that the contact camera lens that the utility model provides a kind of buffer structure of contact camera lens and has this buffer structure, contact camera lens 1 comprise camera lens body 10 and is located at contact camera lens 1 front end place; Wherein:

Contact camera lens 1 is inspected thing in order to closely to observe.In when observation, the front end 10 of camera lens 1 because of need with inspected thing and pressed close to, therefore can be inspected thing and contacted.The utility model mainly is that the front end 10 at contact camera lens 1 is provided with buffer structure 2, to be inspected the collision that thing causes impaired because of need be closely pressing close to observation to avoid camera lens 1 with the buffer structure of making by flexible material 2, and help camera lens 1 to be flat on to be inspected on the thing so that observe.

From the above, buffer structure 2 is made by having flexible material, and it has flexible lasso body 20, is formed with on the lasso body 20 in order to the through hole 200 corresponding to camera lens 10 windows, so that do not hinder the observation of camera lens 1.Soft contact mat portion 21 in the integrally formed ring-type in lasso body 20 lower ends, contact mat portion 21 is extended downwards by lasso body 20 and expansion laterally forms, its bottom face has the surface 210 that can contact with detected material, and can reach moderately smooth with detected material by the flexible of lasso body 20.

At the then integrally formed ring-type sleeve part 22 in lasso body 20 upper ends, sleeve part 22 is in order to be fixed in buffer structure 2 at front end 10 places of camera lens 1.The utility model for embodiment in, sleeve part 22 outwards is equipped with bead 220 by its outside wall surface, and forms the annular ditch groove 100 that inwardly concaves at the window inner ring surface of camera lens 1 front end 10.Because buffer structure 2 is flexible material, so bead 220 can be squeezed in the groove 100, so that sleeve part 22 can be placed in the front end 10 of camera lens 1, thereby reaches the purpose that buffer structure 2 combines with camera lens 1.

Therefore, by above-mentioned structure, the contact camera lens that just can obtain the buffer structure of contact camera lens of the present utility model and have this buffer structure.

Fig. 4 is the utility model in actual view when carrying out the distance element testing.The utility model is with the example of circuit board 3 as detected material; as seen from Figure 4; when the welding hole of circuit board 3 or its copper foil circuit etc. are located to do distance element observation; be subjected to the influence of the height of each electronic package 30 on the circuit board 3 through regular meeting, camera lens 1 is difficult for being flat on the circuit board 3 and detects.Yet, behind buffer structure 2, because its contact mat portion 21 can be cross-placed on each electronic package 30, the flexible of lasso body 20 can appropriateness produce distortion simultaneously, making camera lens 1 be flat on the surface of electronic package 30, and do not have crooked or just do not waiting the phenomenon that influences observation work to produce.Simultaneously, buffer structure 2 flexible also can avoiding own are caused bump to each electronic package 30, thereby can reduce infringement greatly.

In addition, Fig. 5 is the camera lens of another embodiment of the present utility model and the partial sectional view of buffer structure, and it is mainly the embodiment of the sleeve part 22 of buffer structure 2.In the present embodiment, sleeve part 22 is extended upward by its top and is equipped with mantle edge 221, the combination with it so that front end 10 of camera lens 1 can be inserted in the mantle edge 221.

Fig. 6 is the camera lens of another embodiment of the present utility model and the partial sectional view of buffer structure.In the present embodiment, sleeve part 22 is extended upward by its top and cover edge 222 in being equipped with, and interior cover edge 222 can be inserted in the window of camera lens 1 front end 10 and combination with it.

In sum, the utility model is real to be rare novel creation product, it can reach the application target of expection really, solve the defective that exists in the prior art, have novelty and creativeness, meet the requirement of novel patented claim fully, file an application according to Patent Law, would like to ask detailed survey and authorize this case patent, to ensure designer's right.

The above is a preferred embodiment of the present utility model only, is not so promptly limits claim of the present utility model, and the equivalent structure transformation that every utilization the utility model instructions and accompanying drawing content are done all in like manner is included in the claim of the present utility model.
