[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-4 The embodiment of the utility model provides an optical cable termination device, including a box body 1, an inner shell 2 is slidably connected to the box body 1, a fusion unit is arranged on the inner shell 2, and a buckle 3 is connected to the box body 1 through a torsion spring.

[0027] Specifically, an optical cable is a telecommunication transmission line for transmitting optical signals, which is usually composed of one or more optical fibers, and one or more optical fibers are wrapped with a protective layer on the outside; an optical cable termination device refers to a device or mechanism used to connect two optical cables. When the optical cable is terminated, it is generally necessary to fuse one or more optical fibers in the two optical cables together through a fusion unit. The above are all prior arts and will not be repeated here. The innovation of the embodiment of the utility model is that a fusion unit (this is prior art, not shown) is set on the inner liner 2, and then the inner liner 2 is slidably set in the box 1, so that the inner liner 2 can drive the fusion unit to slide in the box 1, so that the fusion unit can be put into the box 1 for easy storage or removed from the box 1 for easy operation by the staff; when the inner liner 2 slides in the box 1 (the staff can manually drive the inner liner 2 to slide in the box 1), the buckle 3 is abutted against its side under the action of the torsion spring until the inner liner 2 moves to the top of its sliding stroke, and the buckle 3 continues to rotate to the bottom of the inner liner 2 under the action of the torsion spring to abut against the bottom of the inner liner 2 (such as Figure 2 As shown), the relative position of the liner 2 and the box body 1 is limited by the buckle 3 to avoid displacement of the liner 2 when the staff performs the welding operation.

[0028] The optical cable termination device provided by the embodiment of the utility model, when in use, opens the box body 1 and moves the inner liner 2 upward, so that the inner liner 2 is removed from the box body 1, and then the fusion unit is moved to a higher position and protrudes from the box body 1. When the inner liner 2 moves to the top of its sliding stroke, the buckle 3 can resist the inner liner 2, thereby limiting the position of the inner liner 2, making it convenient for the staff to operate.

[0029] In another embodiment provided by the utility model, further, a cavity is constructed in the box body 1, and a slide groove 4 is constructed on the inner wall of the cavity, and the liner 2 is slidably connected in the slide groove 4. Specifically, an opening is constructed at the top of the cavity, and the slide groove 4 is vertically constructed on the inner wall of the cavity, so that the liner 2 can be vertically connected in the cavity through the slide groove 4, so that the liner 2 can be moved out of the opening of the cavity or put into the cavity, which is convenient for storing the welding unit on the liner 2 or removing the welding unit on the liner 2 for use.

[0030] Preferably, the cross section of the cavity is larger than the cross section of the liner 2. Specifically, after the liner 2 is received in the cavity, there is still a certain space in the cavity, which is used for the operation of the buckle 3 and other structures to avoid interference between the liner 2 and other structures.

[0031] Furthermore, a connecting groove 5 connected to the cavity is constructed on one side of the box body 1, and the buckle 3 is rotatably connected in the connecting groove 5. One end of the buckle 3 is a resistance end, and the other end is a pressing end. Specifically, the connecting groove 5 is constructed on one side of the box body 1, and the buckle 3 is rotatably connected in the connecting groove 5. The inner wall of the connecting groove 5 can limit the range of rotation of the buckle 3, that is, after the buckle 3 rotates to a certain angle, it will conflict with the inner wall of the connecting groove 5 and cannot rotate; the resistance end is the end of the buckle 3 close to the inner liner 2 and the resistance end is in the cavity, and the pressing end is the other end opposite to the resistance end and the pressing section is in the connecting groove 5; when the inner liner 2 slides in the box body 1, the buckle 3 rotates under the action of the torsion spring so that the resistance end conflicts with the side wall of the inner liner 2, and at this time, the pressing end of the buckle 3 is completely received in the connecting groove 5; when the inner liner 2 slides to the top of its stroke in the box body 1, the buckle 3 continues to rotate under the action of the torsion spring so that the resistance end rotates to the inner liner 2. The bottom of the liner 2, at this time, the pressing end moves out of the connecting groove 5 and contacts the top wall of the connecting groove 5, so that the buckle 3 cannot continue to rotate under the action of the torsion spring, and the inner liner 2 falls on the contact end under the action of gravity, so that the inner liner 2 is supported and restricted by the contact end, and the displacement of the inner liner 2 in the box body 1 is avoided as much as possible, which is convenient for the staff to operate; when the inner liner 2 needs to be put into the cavity, the staff presses the pressing end into the connecting groove 5 from outside the box body 1 to force the buckle 3 to overcome the elastic force of the torsion spring and rotate in the opposite direction, until the contact end moves from the bottom of the inner liner 2 to the side, the inner liner 2 loses the contact of the contact end and is put into the cavity along the slide groove 4, thereby driving the welding unit to move out of the cavity or put into the cavity through the inner liner 2.

[0032] In another embodiment provided by the present invention, further, a top cover 6 is rotatably connected to the box body 1 , a hinged rod 7 is hinged to the top cover 6 , and the other end of the hinged rod 7 is hinged to the inner liner 2 . Specifically, the top cover 6 is rotatably connected to the box body 1 by structures such as hinges, and a lock structure is provided between the top cover 6 and the box body 1, so that the top cover 6 can be locked by the lock after it is rotated to the top of the box body 1, which is convenient for the staff to take the box body 1; a hinged rod 7 is hinged on one side of the top cover 6 close to the box body 1, and the other end of the hinged rod 7 is hinged to the side wall of the inner liner 2. When the top cover 6 is opened, the inner liner 2 can be driven to move along the slide groove 4 through the hinged rod 7 until the top cover 6 is opened, and the inner liner 2 also moves to the top of the slide groove 4 accordingly, so that the inner liner 2 can be moved out of the cavity while the top cover 6 is opened; conversely, when the top cover 6 is closed, the inner liner 2 can be driven to move synchronously to the bottom of the slide groove 4 through the hinged rod 7 structure, so that the inner liner 2 can be stored while the top cover 6 is closed; such a configuration can passively drive the inner liner 2 to move by opening or closing the top cover 6, which is convenient for the staff to use the welding unit or store the welding unit.

[0033] Preferably, a first connecting rod 8 is fixed on the top cover 6. A second connecting rod 9 is fixed on the inner liner 2. Specifically, the first connecting rod 8 is fixed on the top cover 6 so that the top cover 6 is hinged to the hinge rod 7 through the first connecting rod 8; the second connecting rod 9 is fixed on the inner liner 2 so that the inner liner 2 is hinged to the hinge rod 7 through the second connecting rod 9, so that the length of the hinge rod 7 can be shortened and the range of movement of the hinge rod 7 when the top cover 6 is opened or closed can be reduced, and interference between the hinge rod 7 and other structures can be avoided as much as possible.

[0034] Furthermore, the second connecting rod 9 is constructed in an L shape. The second connecting rod 9 includes a vertical section and a horizontal section. Specifically, the second connecting rod 9 is constructed as an L shape as a whole, and includes a vertical section and a horizontal section that are connected to each other, the horizontal section is fixed on the side wall of the inner liner 2, and the vertical section is hinged to the hinge rod 7; when the cavity of the top cover 6 box body 1 is closed, the first connecting rod 8, the hinge rod 7 and the vertical section are maintained on the same vertical plane as a whole, and at this time, the abutting end of the buckle 3 abuts on the hinge rod 7; in the process of opening the top cover 6, the first connecting rod 8 drives the hinge rod 7 to move, so as to drive the second connecting rod 9 and the inner liner 2 to move along the slide groove 4 through the hinge rod 7, and in the process of the top cover 6 driving the inner liner 2 to move, the hinge rod 7 deviates to the side away from the inner liner 2, so as to force the buckle 3 to continue to rotate to the side away from the inner liner 2, until the inner liner 2 moves to a certain height, and the abutting end abuts against the vertical section. At this time, the top cover 6 continues to open to the limit position to drive the inner liner 2 to move to the top of its stroke, so that the resistance end loses the resistance of the vertical section and rotates to the bottom of the horizontal section under the action of the torsion spring. At this time, the inner liner 2 and the horizontal section fall on the resistance end under the action of gravity, so that the connection position between the horizontal section and the side wall of the inner liner 2 is resisted and clamped by the resistance end (at this time, the pressing end resists the inner wall of the connecting groove 5 and cannot continue to rotate), and then the inner liner 2 is moved out and the position of the inner liner 2 is passively restricted during the opening process of the top cover 6, so as to move the fusion unit to a position higher than the box body 1, which is convenient for the connection operation of the optical cable; conversely, when the fusion unit needs to be put into the cavity, pressing the pressing end from the outside of the box body 1 can make the buckle 3 rotate in the opposite direction to release the restriction on the inner liner 2.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
