Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

In the lump referring to figs. 1 to Fig. 2, the telescopic camera structure of the utility model preferred embodiment comprises housing 10 and lens assembly, be provided with baffle plate 12, screw column 14 and guide vane end stop 16 in the described housing 10, described lens assembly comprises spring 21, driven gear 22, wheel cover 23, driving gear 24, limit spring 25, camera 26, lead-in wire 27 and lens bracket 28.

Described spring 21 provides the power of ejection, the one end withstands on the baffle plate 12 of housing 10, the other end withstands on driven gear 22 bottoms, 22 outside weeks of driven gear evenly are provided with three positioning sliding blocks 222, the top is provided with the gear teeth 224, wheel cover 23 is used to limit the motion of driven gear 22 and driving gear 24, wheel cover 23 outsides are provided with a fixed-wing 232, inside is provided with six chutes 234 and is clipped in six press surfaces 236 between the

chute

234,24 outside weeks of driving gear evenly are provided with six positioning sliding blocks 242, the bottom is provided with the gear teeth 244 corresponding with driven gear 22, it is adaptive that described driven gear 22 and driving gear 24 all are installed on wheel cover 23 chutes 242 interior and slide block width and wheel cover 23, camera 26 is placed in the lens bracket 28 and with lead-in wire 27 and is electrically connected, lead-in wire 27 passes limit spring 25 successively, driving gear 24, wheel cover 23, driven gear 22 and spring 21, lens bracket 28 is provided with viewfinder for the corresponding camera 26 of hollow circuit cylinder body structure and side, its outer, bottom forms on a delineation bit slice 282 and the spacer 282 protrudes a guide vane end stop 284, described screw column 14 cooperates with the fixed-wing of wheel cover 23 can fix whole lens assembly in housing 10, the guide vane end stop 16 of housing 10 cooperates with the guide vane end stop 284 of lens bracket 28 can limit lens bracket 28 rotations, make it can only revolve three-sixth turn, prevent that lens assembly from rotating continuously, avoid lead-in wire 27 is damaged, limit spring 25 fifth wheels cover 23 and lens bracket 28, keep lens assembly in housing by spring tension, prevent unexpected the ejection, its spacer 282 of lens bracket 28 At time of ejects props up edge in the housing 10.

With reference to figure 3a, in the time lens bracket 28 will being stretched out, push lens bracket 28, the gear teeth meshing of driven gear 22 and driving gear 24, slide block is corresponding mutually, be in 234 li of the chutes of wheel cover 23 simultaneously, spring 21 promotes driving gear 24 and moves along chute 234, lens bracket 28 is ejected from housing 10, at this, the elastic force of spring 21 is greater than the elastic force of limit spring 25, thereby the pulling force that overcomes limit spring 25 ejects housing 10 with lens bracket 28.

With reference to figure 3b, in the time lens bracket 28 will being shunk, press the lens bracket 28 that stretches out, spring 21 compressions produce moment of torsion, driving driven gear 23 rotates, the chute 234 that its slide block 222 breaks away from wheel cover 23 slides along press surface 236, break away from engagement fully with driving gear 24, and the pressure that relies on spring 21 to provide is still in somewhere on the press surface 236 when the end of movement travel, this moment, spring 21 was in compressive state, driving gear 24 does not obtain the support of driven gear 22, and lens bracket 28 remains on 10 li of housings under the pulling force of limit spring 25.

When pressing lens bracket 28 once more, spring 21 continues compression, produces moment of torsion, and the press surface 236 that drives driven gear 22 edge wheel covers 23 continues to slide, and two gears mesh again, and lens bracket 28 stretches out housing 10.

In the foregoing description, camera 26 can carry out 360 degree rotations along with lens bracket 28, making things convenient for the adjusting of shooting angle, and camera 26 income housings 10 inside can be damaged with len.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
