Detailed Description

The present application is described in further detail below with reference to figures 2-7.

The embodiment of the application discloses an optical adapter capable of adjusting an angle.

Example 1

Referring to fig. 2, the optical adapter includes a bayonet 1, a lens barrel 2, a focus knob 3, and a coupling holder 4. Wherein bayonet 1 passes through screw fixed connection with lens cone 2, and focusing knob 3 rotates to set up and is used for focusing to lens cone 2 at lens cone 2 external application, and connecting seat 4 rotates to be connected in the interface that is used for connecting medical equipment in the bottom of lens cone 2.

Referring to fig. 3 and 4, the lens barrel 2 includes a barrel 21 and a rear protection sheet seat 22 located at the bottom of the barrel 21, and the barrel 21 and the rear protection sheet seat 22 are fixed by clamping. Wherein, the circumference of the bottom of the barrel 21 is provided with a slot 212, and the rear protective sheet seat 22 is provided with an annular block 223 clamped in the slot. In order to facilitate clamping between the cylinder body 21 and the rear protective sheet seat 22 and improve stability after clamping between the cylinder body 21 and the rear protective sheet seat, the bottom of the cylinder body 21 is provided with a guide inclined plane 213 which facilitates clamping, and further reinforcement can be performed between the cylinder body 21 and the rear protective sheet seat 22 through screws.

Referring to fig. 3, rear protective sheet holder 22 has an extension 221 extending to the outer side in the circumferential direction of barrel 21. An installation vacant site 5 for the connecting seat 4 to be arranged is formed between the extending part 221 and the focusing knob 3, the connecting seat 4 is arranged behind the installation vacant site 5, and the focusing knob 3 and the extending part 221 form a limiting structure for limiting the axial movement of the connecting seat 4.

The connecting holder 4 includes a connecting portion 41 located on the outer side in the circumferential direction of the barrel 21, a threaded portion 42 located on the outer side in the circumferential direction of the rear protector piece holder 22 and having a thread on the outer peripheral side, and an abutting portion 43 extending to the outer side of the threaded portion 42 in the circumferential direction of the connecting portion 41. The connecting base 4 is connected to the medical equipment interface through the threaded portion 42, and the abutting portion 43 abuts against the medical equipment interface to complete installation of the connecting base 4.

Further, an installation groove 44 for installing the rear protective sheet holder 22 is formed between the connection portion 41 and the threaded portion 42. The rear protection sheet seat 22 is located inside the mounting groove 44, and the bottom end of the rear protection sheet seat 22 is flush with the bottom end of the connecting seat 4, so that the overall protection of the rear protection sheet seat 22 is realized.

Referring to fig. 5, the coupling holder 4 is provided with a boss 441 in the mounting groove 44 and forms a protruding section 442 and a recessed section 443 by partitioning the mounting groove 44 by the boss 441. The rear protection sheet seat 22 is fixedly provided with a limit pin 222 extending into the concave section 443. The included angle between the two sides of the protruding platform 441 and the center of the mounting groove 44 is 60 °, although the length of the protruding platform 441 can be adjusted in other embodiments.

Referring to fig. 3, since the connecting base 4 is rotatably connected to the lens barrel 2, the position-limiting pin 222 fixed on the rear protection sheet base 22 can freely rotate in the recessed section 443, and the position-limiting pin 222 rotates along with the rotation of the lens barrel 2. When the optical adapter needs to be connected with the interface thread of the medical device, the lens barrel 2 is rotated, the limit pin 222 rotates in the recessed section 443, and the lens barrel 2 is rotated continuously after the limit pin 222 abuts against the boss 441, so that the connecting seat 4 is driven to rotate and screw, and the connection of the whole body is facilitated.

Referring to fig. 2 and 3, in addition, in order to rotate the barrel 21, the top of the barrel 21 protrudes outwards to form a screwing head 24 which is convenient for a user to hold and rotate, the screwing head 24 is of a square structure, and the upper end and the lower end of the focusing knob 3 are respectively close to the screwing head 24 and the connecting seat 4, so that the axial movement of the focusing knob 3 is limited.

Referring to fig. 3 and 6, a spiral focusing slot 31 is formed in the inner side wall of the focusing knob 3, a lens mounting seat 23 is arranged inside the barrel 21, a focusing pin 231 penetrating out of the barrel 21 is arranged on the lens mounting seat 23, the focusing pin 231 penetrates into the focusing slot 31, an axially long through hole 211 for the focusing pin 231 to penetrate out is formed in the barrel 21, the width of the axially long through hole 211 is the same as the diameter of the focusing pin 231, and the lens mounting seat 23 can move axially in the barrel 21 due to the limitation of the focusing pin 231 and the axially long through hole 211 and cannot rotate circumferentially. By rotating the focus knob 3, the lens mounting base 23 can be moved axially by the cooperation of the focus slot 31 and the focus pin 231, thereby realizing focusing.

Of course, since the length of the axially long through hole 211 is limited, the focus knob 3 can be directly rotated when the optical adapter is mounted. In the process of rotating the focusing knob 3, the lens mounting base 23 will move to the limit position first, and then the lens barrel 2 can be driven to rotate by continuously rotating the focusing knob 3. The lens barrel 2 is rotated until the limiting pin 222 abuts against the boss 441, and then the connecting seat 4 can be driven to rotate and screw, so that the integral installation is realized.

In addition, since the lens barrel 2, the connecting seat 4 and the focus knob 3 can be rotated relatively, any one of them is prevented from being deflected after the installation. Rubber pads 6 for increasing frictional resistance are arranged among the barrel body 21, the connecting seat 4 and the focusing knob 3.

The implementation principle of the optical adapter with the adjustable angle in embodiment 1 of the present application is as follows:

the optical adapter is installed by rotating the focusing knob 3 or the lens barrel 2, and then the lens barrel 2 is rotated to drive the bayonet 1 fixed on the lens barrel 2 to rotate synchronously, so that the bayonet 1 can be adjusted to a proper position to connect subsequent objects.

Example 2

Referring to fig. 7, embodiment 2 is different from embodiment 1 in that in the second embodiment, no boss 441 is disposed in the mounting groove 44 of the connecting seat 4, and no limit pin 222 is disposed on the rear protective sheet seat 22.

The connecting socket 4 is provided with rotating protrusions 431 at intervals on the circumferential side of the abutting portion 43 for facilitating the direct rotation of the connecting socket 4 by a human hand.

The implementation principle of an angle-adjustable optical adapter in embodiment 2 of the present application is as follows:

the connection between the connecting seat 4 and the medical equipment interface is realized by directly rotating the connecting seat 4 by rotating the protrusion 431, and then the lens barrel 2 can be rotated to drive the bayonet 1 fixed on the lens barrel 2 to synchronously rotate, so that the bayonet 1 can be adjusted to a proper position to connect subsequent objects.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
