[0025] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Referring to Figures 1-4 , the present utility model provides a self - contained butterfly optical cable 9 introduction device, which includes a hole 2 constructed on a wall surface 1, and further includes a round tube 3 adapted to the hole 2. An elastic member 4 is arranged inside the round tube 3, and plugging blocks 5 are arranged at both ends of the round tube 3.

[0027] Specifically, the butterfly optical cable 9 gets its name because its cross - section resembles a butterfly. It is the best introduction cable for connecting the network backbone to the last one hundred meters inside the user's house. During the process of introducing the optical cable from the outside to the inside, it is inevitable to drill holes to thread the optical cable, which is the prior art and will not be elaborated here. The round tube 3 is constructed in a tubular shape, and its cross - section is annular; the elastic member 4 can be an elastic sheet that deforms under extrusion; the plugging block 5 can be a wooden plug in the prior art or a plug adapted to the inner wall of the round tube 3. It is used to insert into the round tube 3 and block the end of the round tube 3. The plugging block 5 does not limit the position of the optical cable and tries to avoid damaging the optical cable. The innovation point of the embodiment of the present utility model is that the round tube 3 is threaded into the hole 2 on the wall surface 1, so that the butterfly optical cable 9 can be threaded into the room through the round tube 3. In this way, the butterfly optical cable 9 can be introduced into the room, and during the introduction process, through the round tube 3, it can be avoided as much as possible that the inner wall of the hole 2 has spikes that may damage the optical cable; after the optical cable is introduced into the room, the plugging block 5 is inserted into the end of the round tube 3, so that the end of the round tube 3 can be blocked, and it can be avoided as much as possible that air leakage or water leakage occurs at the round tube 3 (the waterproof treatment can be done between the round tube 3 and the hole 2, which is the prior art and will not be elaborated here). During the process of inserting the plugging block 5 into the round tube 3, the elastic member 4 inside the round tube 3 will also be extruded, so that the elastic member 4 deforms in the round tube 3 to abut against the butterfly optical cable 9, and in this way, the function of restricting the position of the optical cable can also be realized.

[0028] For the self - contained butterfly optical cable 9 introduction device provided by the embodiment of the present utility model, after drilling a hole in the wall surface 1, the round tube 3 is inserted into the hole 2 to fill the hole 2, so that the butterfly optical cable 9 can pass through the wall surface 1 through the round tube 3. After the position of the optical cable is determined, the plugging block 5 is inserted into the end of the round tube 3 to block the end of the round tube 3. When the plugging block 5 is inserted into the round tube 3, the elastic member 4 can also be extruded, so that the elastic member 4 deforms to abut against the butterfly optical cable 9, and in this way, the position of the optical cable can be restricted.

[0029] In another embodiment provided by the utility model, further, the outer diameter of the circular tube 3 is equal to the inner diameter of the hole 2. Specifically, when drilling a hole in the wall 1, a suitable drill bit is generally selected for the drilling operation. Accordingly, the circular tube 3 can be constructed in a shape with an outer diameter equal to the diameter of the drill bit, so that the inner diameter of the hole 2 on the wall 1 can be equal to the outer diameter of the circular tube 3, which is convenient for inserting the circular tube 3 into the hole 2; accordingly, the length of the circular tube 3 is equal to the thickness of the wall 1, so that after the circular tube 3 is inserted into the hole 2, both ends can be flush with the wall 1, and unevenness between the circular tube 3 and the hole 2 can be avoided as much as possible.

[0030] Preferably, an introduction channel 6 is configured in the circular tube 3. Specifically, in the above embodiment, the cross-section of the circular tube 3 is annular, that is, the cross-section of the channel in the circular tube 3 for the butterfly optical cable 9 to pass through is circular; in this embodiment, the cross-section of the introduction channel 6 (that is, the channel in the circular tube 3 for the butterfly optical cable 9 to pass through) is trapezoidal, and one side of the introduction channel 6 (the side corresponding to the short side of the trapezoidal cross-section) is configured to be a shape that matches the outer wall of the butterfly optical cable 9 (such as Figure 3 shown), so that the optical cable can be attached to one side of the introduction channel 6 when the optical cable is passed through; in this embodiment, the cross-section of the blocking block 5 plus the cross-section of the butterfly optical cable 9 is equal to the cross-section of the introduction channel 6, which facilitates the blocking block 5 to cooperate with the butterfly optical cable 9 itself to block the end of the round tube 3.

[0031] Furthermore, the elastic member 4 is an arc-shaped elastic sheet. Specifically, in the above embodiment, the elastic member 4 can be a straight elastic sheet, which can be bent after being squeezed by the blocking block 5 to resist the optical cable; in this embodiment, the elastic member 4 is an arc-shaped elastic sheet, which is movably arranged in the introduction channel 6. When the blocking blocks 5 at both ends are inserted into the introduction channel 6, the elastic member 4 can be deformed to resist the optical cable through the squeezing of the two blocking blocks 5, and the arc-shaped elastic sheet resists the optical cable through the side away from the center of the circle, so that the arc-shaped elastic sheet can limit the position of the optical cable while avoiding damage to the optical cable.

[0032] Preferably, one end of the arc-shaped elastic sheet is fixed to the inner wall of the introduction channel 6. Specifically, one end of the arc-shaped elastic sheet is fixed to one side of the introduction channel 6 (the side corresponding to the long side in the trapezoidal cross section), so that after a blocking block 5 is inserted into the circular tube 3, the elastic member 4 can be forced to deform, thereby contacting the optical cable and limiting the position of the optical cable; the advantage of such a setting is that during installation, the open end of the arc-shaped elastic sheet (that is, the unfixed end) is directed toward the indoors, and then the blocking block 5 at the outdoor end of the circular tube 3 is installed. At this time, after the blocking block 5 at the indoor end is inserted into the circular tube 3, the arc-shaped elastic sheet can contact the optical cable to limit the position of the optical cable; during the use of the optical cable, if the position of the optical cable needs to be adjusted, after the blocking block 5 at the indoor end is moved out of the circular tube 3, the arc-shaped elastic sheet is reset and the restriction on the optical cable is released, so that the optical cable can move in the introduction channel 6, which is convenient for the staff to adjust the position of the optical cable indoors.

[0033] Furthermore, the arc-shaped elastic sheet is rotatably connected with a guide wheel 7. Specifically, the guide wheel 7 is rotatably connected to the arc-shaped elastic sheet. When the two blocking blocks 5 are not inserted into the introduction channel 6, the guide wheel 7 can guide the optical cable to facilitate the introduction of the optical cable into the room. After the position of the optical cable is determined, the two blocking blocks 5 are respectively inserted into the two ends of the introduction channel 6, so that the arc-shaped elastic sheet is deformed to drive the guide wheel 7 to squeeze the optical cable, thereby limiting the position of the optical cable through the guide wheel 7 to avoid damage to the optical cable as much as possible.

[0034] Furthermore, the blocking block 5 is detachably connected to the end of the round tube 3. Specifically, the blocking block 5 and the end of the round tube 3 can be connected by interference fit or bolt connection, so that the relative position of the blocking block 5 and the round tube 3 can be limited after the blocking block 5 is inserted into the introduction channel 6, thereby maintaining the state of the elastic member 4 resisting the optical cable after deformation.

[0035] Preferably, the blocking block 5 is connected to the end of the round tube 3 by screws. Specifically, a protrusion can be constructed at one end of the blocking block 5 outside the round tube 3, and the protrusion is fixed to the end of the round tube 3 by screws. The screws can be removed or installed by a screwdriver, so that the staff can install or remove the blocking block 5 by simple tools.

[0036] Furthermore, the blocking block 5 and the elastic member 4 are both on the same side of the butterfly optical cable 9. Specifically, the butterfly optical cable 9 is pressed against the elastic member 4 and is attached to one side of the introduction channel 6, so that there is still a certain gap in the introduction channel 6. At this time, the blocking block 5 can be inserted into both ends of the circular tube 3 to block the circular tube 3. That is, after the blocking block 5 is inserted into both ends of the introduction channel 6, the cross section of the blocking block 5 plus the cross section of the butterfly optical cable 9 is equal to the cross section of the introduction channel 6, so that the end of the introduction channel 6 is blocked by the blocking block 5 and the butterfly optical cable 9.

[0037] Preferably, an extension portion 8 is formed on the plugging block 5. Specifically, in the above embodiments, the cross-section of the plugging block 5 is consistent and adapted to the cross-section of the introduction channel 6, so as to force the elastic member 4 to deform while plugging the introduction channel 6 in cooperation with the optical cable; in this embodiment, the cross-section of the plugging block 5 is larger than the cross-section of the introduction channel 6, so that the plugging block 5 can only plug the end of the introduction channel 6 and cannot enter the introduction channel 6. That is, in this embodiment, the plugging block 5 is only detachably connected to the end of the circular tube 3 and plugs the introduction channel 6. At the same time, an extension portion 8 is formed on the plugging block 5 on the indoor side. The extension portion 8 is on the side of the plugging block 5 body close to the introduction channel 6. When the plugging block 5 on the indoor side plugs the end of the circular tube 3, the extension portion 8 can extend into the introduction channel 6 and squeeze the open end of the elastic member 4, so as to ensure the function of the plugging block 5 while reducing the material used for the plugging block 5.

[0038] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different 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 protection scope of the claims of the present invention.
