Description

In peep cameral lens assembly

Technical field

Peeping cameral lens assembly in the utility model is the image capturing part that is applied in multifunctional digital medical science sight glass picture and text workstation.

Background technology

Lens assembly is the critical component of camera system, mainly partly is made up of endoscope hold assembly, optical lens, optical focusing parts, CCD camera and sealing protection.Its major function is: peep hard mirror in the firmly accurate clamping; Convenient accurate optical focusing; Picture signal opto-electronic conversion and undistorted transmission.Prior art constructions is that hold assembly mainly adopts three resilient clamp structures.The shortcoming of three resilient clamp structures is that employing side screw is fastening, can cause light shaft offset, does not overlap with optical lens, influences picture quality.Clamping grab with in to peep hard mirror be to contact or the line contact, holding force is little, hard mirror easily comes off.The CCD camera directly is connected with camera lens, because its external diameter is circular, during use, makes the directivity of the wayward image of endoscope detecting, brings a lot of inconvenience to use.

Summary of the invention

The purpose of the utility model lens assembly is, overcomes the common deficiency of prior art, satisfies the technical requirement of endoscope system image pickup, handled easily person operation.Structure of the present utility model is, in peep cameral lens assembly, include endoscope hold assembly, optical lens, optical focusing parts, CCD camera, it is characterized in that the fixedly connected coupling nut 13 of oblique sheath 15 1 ends of silicon rubber, the other end and inner by the fixedly connected CCD camera 14 of silicon rubber; The rectangle that is shaped as of the oblique sheath 15 of silicon rubber links to each other the rectangle rounding with ellipse.

The endoscope hold assembly is formed three resilient clamp structures by adjusting ring 1, gripper jaw 2, bearing needle 3, grip slipper 4, sliding ring 5, flat shoulder screw 10, compression spring 19; Drive at the center in the hole of each sheet one end of three gripper jaws 2, and drive at the edge in the hole of the other end, is eccentric orfice; Be fixed with bearing needle 3 in each hole; Gripper jaw 2 exposes in the adjusting ring endoporus; Have three grooves that penetrate on adjusting ring 1 end face, by flat shoulder screw 10 fixedly connected sliding rings 5; Protection glass 7, O RunddichtringO 8 grip slipper 4 and outside between the lens barrel 9, fixing by screw 6, as the preceding sealing of optical lens; Compression spring 19 is stuck between grip slipper 4 and the sliding ring 5; The needle roller 3 of one end of three gripper jaws 2 is enclosed within on the hole on the grip slipper, and the needle roller 3 on the other end is slidingly connected in three grooves that penetrate on adjusting ring 1 end face; Bearing needle 17 is installed on the bearing 16, and bearing 16 is threaded by square tooth helicla flute and slides in the elongated slot in the lens barrel outside with focusing thumb wheel 11; Needle roller is inserted in the poke hole of optical lens 18; Focusing thumb wheel 11 1 ends are by O RunddichtringO 12 and outer lens barrel 9 sealings, and the other end is by O RunddichtringO 12 and coupling nut 13 sealings; Coupling nut 13 is fixedlyed connected with outer lens barrel 9; Optical lens 18 is contained in the endoporus of outer lens barrel.

Gripper jaw 2 broads and big fillet

The endoscope hold assembly is selected three resilient clamp schemes, and it has the automatic centering heart, clamps advantages such as difficult drop-off.In order to clamp the hard mirror of various brands more reliably, gripper jaw design broad, make it to stretch out more, the compression adjustment amount is big during clamping.We select bearing needle for use the gripper jaw mandrel, and grip strength is big.In addition, fallen the angle, garden, made the clamping line become clamping face at the gripper edge of gripper jaw.Therefore, hold assembly can adapt to the clamping of various hard mirrors, and the automatic centering heart and bearing accuracy height are reliable and stable.The optical focusing parts side of being designed to tooth helicla flute adds rolling bearing and stirs the focusing mode, and two ends are with the sealing of O type ring, focus meticulous steadily, good hand touch, sealing be reliable, whole camera lens is placed in the water immersion can seep water.The lens assembly specialized designs inclined to one side garden shape silicone rubber jacket, it is comfortable safe that the operator was held, and determines the orientation of image again easily.

Peep hard mirror in the easy reliable accurately various brands of clamping of the utility model lens assembly energy and carry out image capture; Accurate height carries out the transmission and the conversion of picture signal with guaranteeing the quality; Reliably photoelectric device is made anticorrosion moisture seal; The lens performance quality has reached the high-quality level.
