Description

[0001] The parent application of the present divisional application has an application number of 2024114922003 and an application date of October 24, 2024, and has an invention name of "Optical fiber connecting structure and super-emulsion glass cutting machine". TECHNICAL FIELD

[0002] The present application relates to the field of super-emulsion glass cutting machines, in particular to an optical fiber connecting structure and super-emulsion glass cutting machine. BACKGROUND

[0003] The vitreous cutting machine for vitreous body cutting surgery is referred to as a glass cutting machine. The vitreous body is a semi-solid gel-like substance inside the eye, which fills the vitreous cavity. Under normal circumstances, the vitreous body has good light transmission and can make the retina adhere to the choroid. If the vitreous body is diseased, the person may see insects flying in front of his eyes when looking at things, and in severe cases, the person may lose his eyesight, and even the surrounding tissue of the vitreous body may be diseased, such as retinal detachment, which may further damage the entire eyeball. In medical clinical surgery, the glass cutting machine can be used to cut the cloudy vitreous body or cut the vitreoretinal traction to restore the transparent refractive medium and promote the retinal repositioning, and treat the vitreoretinal diseases to restore the visual function of the patient.

[0004] During the vitreous cutting surgery, the light fiber is used to transmit light to the eye to form a light column to form the Tyndall effect, which facilitates the identification of the relatively transparent vitreous body. In the related technology, the optical fiber is connected to the optical fiber connecting seat on the main machine of the glass cutting machine through the optical fiber connecting head. When the optical fiber connecting head is connected to the optical fiber connecting seat, it is difficult to determine whether the optical fiber connecting head is inserted in place relative to the optical fiber connecting seat.

[0046] Referring to Figures 1 to 4 As shown in the drawings, the present disclosure provides an optical fiber connection structure. The optical fiber connection structure comprises a connection seat 100, a connection head 200 and an elastic member 300.

[0047] In the present embodiment, the connection seat 100 is connected to a signal circuit, and a sleeve 110 is provided thereon. A first optical fiber 120 is provided through the connection seat 100 and exposed in the sleeve 110. In the present embodiment, the connection head 200 comprises an optical fiber tube 210 and a locking assembly 220 sleeved on the optical fiber tube 210. A second optical fiber 230 is provided through the optical fiber tube 210. The optical fiber tube 210 can be inserted into the sleeve 110, and the locking assembly 220 can be detachably connected with the sleeve 110. When the locking assembly 220 is connected with the sleeve 110, the optical fiber tube 210 is in contact with the connection seat 100. The elastic member 300 is arranged between the connection head 200 and the connection seat 100. The elastic member 300 is in contact with the locking assembly 220, and the elastic member 300 causes the locking assembly 220 to have a tendency to move away from the connection seat 100. The elastic member 300 is used to connect the signal circuit. When the connection head 200 and the connection seat 100 are inserted in place, a conduction loop is formed between the signal circuit, the elastic member 300, the locking assembly 220 and the optical fiber tube 210 on the connection head 200, and the connection seat 100.

[0048] In the present embodiment, in the case where the connection seat 100 and the connection head 200 are inserted in place, the first optical fiber 120 provided through the connection seat 100 and provided in the sleeve 110 and the second optical fiber 230 provided through the optical fiber tube 210 are coaxial and opposite.

[0049] In the embodiment, the ferrule 200 and the connector 100 in the fiber-optic connection structure are connected in the case that the elastic member 300 accesses the signal circuit. Whether the ferrule 200 is inserted into the connector 100 in place can be identified by detecting whether the elastic member 300, the ferrule 200, and the connector 100 are in contact and conductive. It can be understood that whether the ferrule 200 is inserted into the connector 100 in place can be determined by detecting whether the loop formed by the signal circuit, the elastic member 300, the locking assembly 220 on the ferrule 200, the fiber tube 210, and the connector 100 is in contact and conductive. Exemplarily, the signal circuit accessed by the elastic member 300 can be a main machine of a super-lactation glass cutting machine.

[0050] The principle is that, in the case that the elastic member 300 accesses the signal circuit, the ferrule 200 and the connector 100 in the fiber-optic connection structure are connected, the fiber tube 210 on the ferrule 200 is inserted into the sleeve 110 on the connector 100, and the locking assembly 220 and the sleeve 110 are connected, so that the locking assembly 220 is in contact and conductive with the elastic member 300 and extrudes the elastic member 300. As the locking assembly 220 on the ferrule 200 and the sleeve 110 are continuously connected, the ferrule 200 is in contact and conductive with the connector 100 through the fiber tube 210. Thus, the elastic member 300, the locking assembly 220 on the ferrule 200, the fiber tube 210, and the connector 100 are in contact and conductive in sequence. If the elastic member 300, the locking assembly 220 on the ferrule 200, the fiber tube 210, and the connector 100 are in contact and conductive in sequence, it indicates that the loop formed by the signal circuit, the elastic member 300, the locking assembly 220 on the ferrule 200, the fiber tube 210, and the connector 100 is in contact and conductive, and the ferrule 200 is inserted into the connector 100 in place. Otherwise, it indicates that the loop formed by the signal circuit, the elastic member 300, the locking assembly 220 on the ferrule 200, the fiber tube 210, and the connector 100 is disconnected, and the ferrule 200 is not inserted into the connector 100 in place. Therefore, the fiber-optic connection structure provided in the embodiment has the function of detecting whether the ferrule 200 is inserted into the connector 100 in place, so that the user can perceive and identify whether the ferrule 200 is inserted into the connector 100 in place during the process of connecting the ferrule 200 and the connector 100 in the fiber-optic connection structure, thereby effectively ensuring the coupling efficiency of the ferrule 200 and the connector 100.

[0051] In addition, in the embodiment, the elastic member 300 causes the locking assembly 220 to have a tendency to move away from the connecting seat 100, and thus the locking assembly 220 and the elastic member 300 can be in stable contact with each other, which effectively ensures the stability of the conduction between the locking assembly 220 and the elastic member 300, and further ensures the stable and reliable detection and identification of the signal circuit on the plugging of the connector 200 into the connecting seat 100. In addition, the tendency of the locking assembly 220 to move away from the connecting seat 100 caused by the elastic member 300 can effectively prevent the connection between the locking assembly 220 and the sleeve 110 from loosening.

[0052] In the embodiment, as shown in Figure 1 , Figure 2 , Figures 4 to 6 , the locking assembly 220 can be connected with the sleeve 110 in a threaded manner. For example, when the connector 200 is connected with the connecting seat 100, the optical fiber tube 210 is inserted into the sleeve 110, and the locking assembly 220 is screwed relative to the sleeve 110 to drive the optical fiber tube 210 to move close to the connecting seat 100. When the optical fiber tube 210 abuts against the connecting seat 100, the locking assembly 220 just contacts and presses the elastic member 300, and the elastic member 300, the locking assembly 220, the optical fiber tube 210 and the connecting seat 100 are sequentially in conduction. Thus, whether the connector 200 is plugged into the connecting seat 100 can be identified by detecting whether the elastic member 300, the locking assembly 220, the optical fiber tube 210 and the connecting seat 100 are in conduction.

[0053] In the embodiment, the locking assembly 220 can include a threaded sleeve 221, an insulating ring 222, a hand-tightening ring 223 and a fastener 224. The threaded sleeve 221 is rotatably sleeved on the optical fiber tube 210, and the threaded sleeve 221 can be sleeved on the sleeve 110 and be threadedly connected with the sleeve 110. The insulating ring 222 is sleeved on the threaded sleeve 221. The hand-tightening ring 223 is sleeved on the insulating ring 222. The fastener 224 is sequentially arranged through the circumferential portion of the hand-tightening ring 223 and the circumferential portion of the insulating ring 222 and abuts against the circumferential portion of the threaded sleeve 221, and the fastener 224 is threadedly connected with the hand-tightening ring 223. In the embodiment, the insulating ring 222 can make the hand-tightening ring 223, the fastener 224, the threaded sleeve 221 and the optical fiber tube 210 sequentially in conduction, which effectively prevents the hand-tightening ring 223 from directly conducting with the threaded sleeve 221 beyond the fastener 224. It can be understood that, in the case that the elastic member 300 is connected to the signal circuit, when the connector 200 is plugged into the connecting seat 100, a conduction loop is formed between the signal circuit, the elastic member 300, the hand-tightening ring 223, the fastener 224, the threaded sleeve 221, the optical fiber tube 210 and the connecting seat 100, which can effectively ensure the stability of the current signal in the signal circuit, and further ensure the stable and reliable identification of whether the connector 200 is plugged into the connecting seat 100.

[0054] In the embodiment, the periphery of the optical fiber tube 210 is provided with a first annular boss 211, the second annular boss 2211 is formed on the inner side wall of the end of the threaded sleeve 221 away from the connector seat 100 and extends radially, the second annular boss 2211 is located on the side of the first annular boss 211 away from the connector seat 100, and the end of the second annular boss 2211 facing the first annular boss 211 can abut against the end of the first annular boss 211 facing the second annular boss 2211. In the embodiment, when the connector 200 is inserted into the connector seat 100, the optical fiber tube 210 abuts against the connector seat 100, and the end of the second annular boss 2211 facing the first annular boss 211 abuts against the end of the first annular boss 211 facing the second annular boss 2211, so that the connector seat 100 and the second annular boss 2211 can clamp the optical fiber tube 210, thereby effectively ensuring the stable and reliable conduction between the threaded sleeve 221, the optical fiber tube 210 and the connector seat 100.

[0055] In the embodiment, the periphery of the threaded sleeve 221 can be provided with a third annular boss 2212, and the periphery of the third annular boss 2212 is in abutment with the inner annular surface of the insulating ring 222. In the embodiment, the threaded sleeve 221 is in abutment with the inner annular surface of the insulating ring 222 through the periphery of the third annular boss 2212, so that the threaded sleeve 221 and the insulating ring 222 can be fixed relative to each other in the radial direction, which is stable and reliable, and can effectively reduce the contact area with the insulating ring 222, i.e., reduce the contact friction between the threaded sleeve 221 and the insulating ring 222, thereby facilitating the assembly between the threaded sleeve 221 and the insulating ring 222.

[0056] In the embodiment, the fastener 224 can abut against the third annular boss 2212. In the embodiment, the periphery of the third annular boss 2212 is in abutment with the inner annular surface of the insulating ring 222, and the fastener 224 abuts against the third annular boss 2212, which can effectively prevent the threaded sleeve 221 from being skewed relative to the hand-tightening ring 223, and can stably press and fix the threaded sleeve 221 in the hand-tightening ring 223.

[0057] In the embodiment, the inner annular surface of the hand-tightening ring 223 can be stepped, including a first inner annular surface 2231, a second inner annular surface 2232, and a stepped surface 2233 arranged between the first inner annular surface 2231 and the second inner annular surface 2232. The diameter of the first inner annular surface 2231 is greater than that of the second inner annular surface 2232. The first inner annular surface 2231 is located on the side of the second inner annular surface 2232 close to the connecting seat 100. The insulating ring 222 is arranged in the first inner annular surface 2231 and is in close contact with the first inner annular surface 2231. This can ensure that the hand-tightening ring 223 and the insulating ring 222 are relatively fixed in the radial direction, which is stable and reliable. Moreover, the end of the insulating ring 222 away from the connecting seat 100 is in close contact with the stepped surface 2233, which can realize the positioning of the insulating ring 222 relative to the hand-tightening ring 223 in the axial direction, which is stable and reliable.

[0058] In other embodiments, the locking assembly 220 can also be connected to the sleeve 110 by clamping or other connection methods, which are not limited in the present disclosure.

[0059] In the embodiment, the signal circuit can be connected with a current detection device (not shown). The current detection device can form a loop with the signal circuit, the elastic member 300, the locking assembly 220, the optical fiber tube 210, and the connecting seat 100. The current detection device can detect whether there is current in the loop to identify whether the connector 200 is inserted into the connecting seat 100 in place.

[0060] In a feasible implementation, the optical fiber connection structure can include a plurality of connectors 200. The connecting seat 100 is connected with one of the connectors 200. The resistances of the fasteners 224 of each of the plurality of connectors 200 are different. When fasteners 224 with different resistances are connected in series in the signal circuit, the current values flowing through the signal circuit are different. By detecting the current value of the signal circuit, the model and type of the connected connector 200 can be identified.

[0061] For example, the material of the fastener 224 includes but is not limited to metal aluminum, aluminum alloy, or stainless steel.

[0062] In other embodiments, the signal circuit can also be detected by a voltage detection device or other detection device, which is not limited in the present disclosure.

[0063] In a feasible implementation, the connector 200 further includes a protective sleeve 240. The second optical fiber 230 is arranged in the protective sleeve 240, and the protective sleeve 240 is arranged on the end of the optical fiber tube 210 away from the connecting seat 100. In the embodiment, the protective sleeve 240 can protect the second optical fiber 230 from external force and environment, and maintain the transmission performance of the second optical fiber 230.

[0064] Exemplarily, the protective sleeve 240 can be made of a high-strength material, capable of bearing tension, pressure and bending, preventing the optical fiber from being broken or damaged in operation.

[0065] In an embodiment, as shown in Figure 4 One side of the connecting seat 100 is provided with an annular groove 101, and the sleeve 110 is inserted into the annular groove 101, facilitating the positioning and assembly of the sleeve 110 relative to the connecting seat 100, and effectively ensuring the coaxial accuracy between the first optical fiber 120 and the second optical fiber 230 when the connector 200 is inserted into place relative to the connecting seat 100.

[0066] In an embodiment, as shown in Figure 4 The inner side wall of one end of the sleeve 110 extends along the axial direction of the sleeve 110 to form an annular table 111, which is inserted into the annular groove 101, facilitating the positioning and assembly of the sleeve 110 relative to the connecting seat 100 along the axial direction.

[0067] In an embodiment, as shown in Figure 7 The elastic member 300 includes an open ring portion 310, and the two ends of the open ring portion 310 extend to form support arm portions 320, respectively. The open ring portion 310 is sleeved on the sleeve 110, and the support arm portions 320 are used to connect the signal circuit. In this embodiment, when the connector 200 is inserted into place relative to the connecting seat 100, the open ring portion 310 abuts against the locking assembly 220, realizing the contact and conduction of the elastic member 300, the locking assembly 220, the optical fiber tube 210 and the connecting seat 100 in sequence, and being stable and reliable.

[0068] Exemplarily, the end of the support arm portion 320 can be relatively fixed with the connecting seat 100, and when the open ring portion 310 abuts against the locking assembly 220, the elastic member 300 makes the locking assembly 220 have a tendency to move away from the connecting seat 100.

[0069] Specifically, the open ring portion 310 abuts against the hand screw ring 223.

[0070] In an embodiment, the elastic member 300 can also be a spring or other elastic member, which is not limited in the present disclosure.

[0071] The present embodiment also provides an ultra-lactation glass cutting machine, which includes the optical fiber connecting structure. Through the arrangement of the optical fiber connecting structure, the coupling efficiency of the optical fiber can be effectively ensured.

[0072] In the present embodiment, the ultra-lactation glass cutting machine also includes a glass cutting machine host (not shown), and the connecting seat 100 of the optical fiber connecting structure is connected with the glass cutting machine host.
