[0037] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 2As shown, this utility model embodiment provides a fixing clamp for optical cables, including: a base 100, a clamp assembly 200, and a fixing assembly 300. The base 100 is disposed on the outside of an external device. The clamp assembly 200 is disposed on the top of the base 100, and the clamp assembly 200 is provided with a fixing hole 201 for fixing the optical cable. One end of the fixing assembly 300 passes through the base 100 and extends into the external device. The fixing assembly 300 includes: a connector 301, a positioning rod 302, a positioning bead 305, a positioning element 306, a compression spring 308, and a locking element 309. The connector 301 is disposed inside the external device, and a connecting hole 3011 is provided in the middle of the connector 301. The connecting hole 3011 is stepped, with the smaller diameter end of the connecting hole 3011 facing away from the external device. An inclined limiting slope 3012 is provided at the step of the connecting hole 3011. One end of the positioning rod 302 extends through the clamp assembly 200 into the connecting hole 3011. The positioning rod 302 has a mounting hole 303 in its middle portion, and its sidewalls are provided with multiple positioning holes 304 around its axis. A positioning bead 305 is disposed within the positioning hole 304, with a portion of the positioning bead 305 located within the mounting hole 303. A positioning element 306 is disposed within the mounting hole 303, and its bottom sidewall is an inclined pressing surface 307, which contacts the positioning bead 305 located within the mounting hole 303. A compression spring 308 is disposed within the mounting hole 303, with one end of the compression spring 308 abutting against the top of the positioning element 306. One end of the locking member 309 extends into the mounting hole 303 and is threadedly connected to the mounting hole 303. The end of the locking member 309 located in the mounting hole 303 abuts against the other end of the compression spring 308.

[0039] To facilitate the installation of the base 100, the connector 301 of the fixing component 300 is first installed on the external device using anti-loosening screws, and a connecting hole 3011 is provided in the middle of the connector 301. The connecting hole 3011 is a stepped hole, and an inclined limiting slope 3012 is provided at the step of the stepped hole.

[0040] When installing the clamp assembly 200, the clamp assembly 200 is placed on an external device. Then, the positioning rod 302, which is equipped with the positioning bead 305, the positioning element 306, and the compression spring 308, is installed on the clamp assembly 200. One end of the positioning rod 302 extends into the connecting hole 3011 of the connector 301. Then, one end of the locking element 309 is threadedly connected to the mounting hole 303 of the positioning rod 302. During the locking process, the locking element 309 moves towards the connector 301 along the axis of the mounting hole 303. During the movement, the locking element 309 drives the compression spring 308 and the positioning element 306 to move. During the movement, the pressing surface 307 of the positioning element 306 presses the positioning bead 305 outward. A portion of the positioning bead 305 is squeezed out of the positioning rod 302 and abuts against the limiting inclined surface 3012 on the connector 301. At this time, the compression spring 308 is in a compressed state.

[0041] After the optical cable is installed on the clamp assembly 200, some parts may experience thermal expansion and contraction due to environmental changes during use. Therefore, the fixing assembly 300 with the above-described structure is used to connect the base 100 to the external equipment. When thermal expansion and contraction occur, the clamping force is adjusted by the clamping spring 308 provided in the fixing assembly 300 to prevent the base 100 from becoming loose from the external equipment.

[0042] During use, the external device will vibrate, and the vibration will be transmitted to the fixing clamp. The vibration can be eliminated by the compression spring 308 in the fixing component 300, so as to prevent the base 100 from falling off the external device due to vibration and affecting the normal use of the optical cable.

[0043] In another embodiment, such as Figure 3 As shown, the fixing clamp further includes a buffer pad 400, which is disposed at the bottom of the base 100, and the buffer pad 400 is provided with a through hole for the fixing component 300 to pass through.

[0044] To reduce the impact of external equipment vibration on the fixing fixture, a buffer pad 400 is provided between the base 100 and the external equipment. The buffer pad 400 absorbs part of the vibration, and the remaining vibration is eliminated by the compression spring 308 provided in the fixing assembly 300.

[0045] It should be noted that the cushioning pad 400 is made of rubber, and the size of the cushioning pad 400 is larger than the size of the base 100, so that the base 100 can be placed completely on the cushioning pad 400.

[0046] In another embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the clamp assembly 200 includes a lower clamp portion 202 and an upper clamp portion 204. The lower clamp portion 202 is disposed on the top of the base 100, and a first fixing opening 203 is provided on the top of the lower clamp portion 202. The upper clamp portion 204 is disposed on the top of the lower clamp portion 202, and a second fixing opening 205 matching the first fixing opening 203 is provided on the bottom of the upper clamp portion 204. The first fixing opening 203 and the second fixing opening 205 form a fixing hole 201 for fixing the optical cable. The lower clamp portion 202 and the upper clamp portion 204 are connected by the fixing assembly 300.

[0047] In order to facilitate fixing the optical cable in the clamp assembly 200, the clamp assembly 200 is divided into a lower clamp 202 and an upper clamp 204. The lower clamp 202 and the upper clamp 204 are connected by a fixing component 300.

[0048] To facilitate the fixing of the optical cable, a first fixing opening 203 is provided at the top of the lower part 202 of the clamp, and a second fixing opening 205 is provided at the lower part of the upper part 204 of the clamp. When the lower part 202 and the upper part 204 of the clamp are connected by the fixing assembly 300, the first fixing opening 203 and the second fixing opening 205 form a fixing hole 201 for fixing the optical cable.

[0049] The use of fixing component 300 to fix the lower part 202 and the upper part 204 of the clamp is to prevent the lower part 202 and the upper part 204 of the clamp from loosening or falling off due to weather or vibration during use, which would affect the fixation of the optical cable.

[0050] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamp assembly 200 further includes an adjusting screw 206 and an adjusting arc plate 207. One end of the adjusting screw 206 passes through the upper part 204 of the clamp and extends into the fixing hole 201, and the adjusting screw 206 is threadedly connected to the upper part 204 of the clamp. The adjusting arc plate 207 is disposed at the end of the adjusting screw 206 located in the fixing hole 201.

[0051] To facilitate the fixing of optical cables of different diameters, an adjusting screw 206 is provided on the upper part 204 of the clamp. The adjusting screw 206 is threadedly connected to the upper part 204 of the clamp. After connection, one end of the adjusting screw 206 extends into the fixing hole 201, and the other end is located at the top of the upper part 204 of the clamp. An adjusting arc plate 207 is provided at the end of the adjusting screw 206 located in the fixing hole 201.

[0052] In use, in order to facilitate the fixing of optical cables of different diameters, after the lower part 202 and the upper part 204 of the clamp are fixed, the adjusting screw 206 is adjusted to drive the adjusting arc plate 207 to move, and the distance between the adjusting arc plate 207 and the first fixed opening 203 of the lower part 202 of the clamp is adjusted.

[0053] In one embodiment, such as Figure 3 and Figure 4 As shown, the clamp assembly 200 further includes a contact plate 208, which is mounted on one end of the adjusting arc plate 207 facing the lower part 202 of the clamp.

[0054] In order to prevent the clamp assembly 200 from damaging the protective layer of the optical cable when fixing the optical cable, a contact plate 208 is provided on the side of the adjusting arc plate 207 facing the lower part 202 of the clamp.

[0055] It should be noted that the contact plate 208 is made of rubber.

[0056] In another implementation, such as Figure 4 As shown, to facilitate the retraction of the adjusting arc plate 207 and the contact plate 208 into the upper part 204 of the clamp, a receiving groove 209 is provided at the bottom of the second fixing opening 205 of the upper part 204 of the clamp. When the outer diameter of the optical cable matches the size of the fixing hole 201, the adjusting arc plate 207 and the contact plate 208 are completely retracted into the receiving groove 209.

[0057] When the size of the optical cable matches the size of the fixing hole 201, in order to avoid disassembling the adjusting arc plate 207, a receiving groove 209 is provided at the bottom of the second fixing opening 205 of the upper part 204 of the clamp. The adjusting arc plate 207 and the contact plate 208 provided on the adjusting arc plate 207 are brought into the receiving groove 209 together by adjusting the screw 206.

[0058] In one embodiment, such as Figure 3 and Figure 4 As shown, the clamp assembly 200 further includes a locking spring 210, which is sleeved on the adjusting screw 206 and is located between the upper part 204 of the clamp and the nut of the adjusting screw 206 after installation.

[0059] To prevent the adjusting screw 206 from loosening due to weather conditions or vibration, which would prevent the adjusting arc plate 207 from effectively fixing the optical cable.

[0060] In one embodiment, such as Figure 3As shown, there are two locking springs 210, which are sleeved on the adjusting screw 206. After the two locking springs are installed, they are respectively located between the adjusting arc plate 207 and the upper part of the clamp 204 and between the upper part of the clamp 204 and the nut of the adjusting screw 206.

[0061] To prevent the adjusting screw 206 from loosening due to alternating high and low temperatures or vibration, which would prevent the adjusting arc plate 207 from effectively securing the optical cable, two locking springs 210 are fitted onto the adjusting screw 206. After installation, the two locking springs 210 are located between the adjusting arc plate 207 and the upper part of the clamp 204, and between the upper part of the clamp 204 and the nut of the adjusting screw 206, respectively.

[0062] In one embodiment, such as Figure 2 As shown, the mounting hole 303 includes: a countersunk head 3031, a clearance portion 3032, a connecting portion 3033, and a mounting portion 3034. The countersunk head 3031 is located at the top of the positioning rod 302. The clearance portion 3032 is located at the other end of the positioning rod 302, and one end of the positioning member 306 can extend into the clearance portion 3032. The connecting portion 3033 is located between the countersunk head 3031 and the clearance portion 3032, and a connecting thread is provided on the side wall of the connecting portion 3033. The size of the connecting portion 3033 is smaller than the size of the countersunk head 3031, and the locking member 309 matches the connecting portion 3033. The mounting portion 3034 is located between the connecting portion 3033 and the clearance portion 3032, and the size of the mounting portion 3034 is smaller than the size of the connecting portion 3033. After installation, the positioning member 306 and the compression spring 308 are located within the mounting portion 3034.

[0063] In use, to facilitate the installation and positioning of the positioning element 306, positioning bead 305, and compression spring 308, the mounting hole 303, from top to bottom, consists of a countersunk head 3031, a connecting part 3033, a mounting part 3034, and a clearance part 3032. The positioning hole 304 for installing the positioning bead 305 is located on the side wall of the mounting part 3034. After the positioning bead 305 is installed, the positioning element 306, compression spring 308, and locking element 309 are sequentially installed into the mounting hole 303.

[0064] After the positioning component 306 is installed, one end of the positioning component 306 is located inside the mounting part 3034, and the other end is located inside the clearance part 3032.

[0065] When the locking member 309 is locked, the compression spring 308 drives the positioning member 306 to move towards the outside of the positioning rod 302. At this time, the pressing surface 307 of the positioning member 306 contacts the positioning bead 305 and presses the positioning bead 305 towards the outside of the positioning rod 302, so that the positioning bead contacts the limiting inclined surface 3012 of the connecting member 301, thereby fixing the fixing component 300.

[0066] In one embodiment, such as Figure 2 As shown, the positioning hole 304 is trumpet-shaped, with the larger diameter end of the positioning hole 304 located close to the mounting hole 303, and the smaller diameter end of the positioning hole 304 located on the outer wall of the positioning rod 302.

[0067] To prevent the positioning bead 305 from being squeezed out of the positioning hole 304 during compression, the positioning hole 304 is designed in a trumpet shape. The smaller end of the positioning hole 304 is located on the outer wall of the positioning rod 302, and the larger end is located on the wall of the mounting hole 303. The trumpet-shaped positioning hole 304 is used to limit the positioning bead.

[0068] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
