Description

Technical Field

[0001] The invention relates to the field of cable fixing, and in particular to a fastening device for fixing cables. Background Art

[0002] In various cable laying and fixing scenarios, cable fastening devices are crucial. The fastening force of some fastening devices cannot be adjusted. For example, some simple plastic cable ties cannot change their fastening degree once fastened. If the fastening force is too large during installation, the outer sheath of the cable may be damaged, especially for some thinner or more fragile cables, such as optical fiber cables, which may affect signal transmission.

[0003] The Chinese patent with announcement number CN104428571B discloses a fastening device for fixing cables, but the device still does not break away from the limitations of the traditional clamp design. Although the device can achieve better fixation of specific cables through clamping ribs with slightly smaller inner diameters, the overall design is based on considerations of cables of specific sizes. For cables of different diameters, if the diameter is significantly different from the design specifications, they may not be effectively fixed. If the cable is too thin, the clamping ribs cannot provide sufficient clamping force; if the cable is too thick, it cannot be placed in the clamp, and lacks adaptability to changes in cable diameter.

[0004] Secondly, during the installation process of the clamp-type fastening device, tools are usually required for tightening operations, which is cumbersome and inefficient. Moreover, during the tightening process, it is difficult to ensure that the force is evenly applied to each part, and it is easy to cause partial over-tightening or over-loosening, which affects the overall tightening effect.

[0005] In addition to the clamp-type fastening device, some other types of fastening devices can solve the cable fixing problem to a certain extent, but they also have corresponding defects. For example, some simple binding fastening devices, although they can adapt to cables of different specifications, have poor fixing stability. In the case of vibration, external force pulling, etc., the cables are easy to break free from the binding, causing safety hazards. In addition, some fastening devices that use a rigid clamping method lack flexible positioning of the cables, which can easily cause damage to the cables, and also have the problem of insufficient adaptability to cables of different specifications.

[0019] Furthermore, the positioning mechanism also includes two positioning racks, two positioning gears and two pushing racks. The two positioning racks are respectively arranged on both sides of the positioning plate, the two positioning gears are respectively rotatably connected to the two lifting slides, the two positioning gears are respectively meshed with the two positioning racks, the two pushing racks are respectively fixedly connected to the two clamping frames, and the two pushing racks are respectively meshed with the two positioning gears.

[0020] Furthermore, a plurality of anti-slip grooves are formed in an array at equal intervals on the upper end of the abutting frame.

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] refer to Figures 1 to 8 , a fastening device for fixing a cable, comprising:

[0042] Main frame 2;

[0043] A turntable 3 is rotatably arranged on one side of the main frame 2;

[0044] The main gear 4 is coaxially fixed to the lower end of the turntable 3 and is rotatably connected to the main frame 2;

[0045] A main gear plate 5 meshes with the main gear 4 and is rotatably connected to the main frame 2;

[0046] The limiting plate 12 is arranged below the rotating disk 3 and is fixedly connected to the main frame 2;

[0047] The positioning plate 7 is arranged beside the limiting plate 12 and is fixedly connected to the main frame 2;

[0048] The positioning mechanism 6 is arranged beside the positioning plate 7. The positioning mechanism 6 includes two lifting slides 19 and two abutting frames 16. The two lifting slides 19 are slidably arranged on both sides of the positioning plate 7. The two abutting frames 16 are slidably connected to the two lifting slides 19 respectively. When the main gear plate 5 rotates, the two abutting frames 16 are driven to move;

[0049] The flipping mechanism 24 is connected to the main frame 2, and includes a flipping frame 33 and a pressing frame 35. One end of the flipping frame 33 is rotatably connected to the main frame 2, and the pressing frame 35 is slidably arranged on a side of the flipping frame 33 close to the main frame 2. When the main gear plate 5 rotates, it drives the flipping frame 33 to flip.

[0050] When the device is used to fix the cable 1, the operator directly presses the main frame 2 onto the cable 1, and then the operator rotates the turntable 3. After the turntable 3 rotates, it drives the main toothed disc 5 to rotate through the main gear 4. When the main toothed disc 5 rotates, it drives the clamping frame 16 to move. At the same time, the rotation of the main toothed disc 5 will also drive the flip frame 33 to flip, and finally the pressing frame 35 and the two clamping frames 16 are pressed on the outside of the cable 1, thereby completing the fixation of the cable 1.

[0051] In order to flexibly position the cable 1 so that after the main frame 2 is pressed on the cable 1, multiple contact points are formed between the cable 1 and the main frame 2, the following features are specifically set:

[0052] The positioning mechanism 6 further includes a plurality of positioning sleeves 8, a plurality of limiting pins 10 and a plurality of limiting springs 11. The plurality of positioning sleeves 8 are arranged in an array with equal intervals for sliding along the positioning plate 7 (refer to Figure 7 and Figure 8 ), a number of limit pins 10 are respectively fixedly connected to a number of positioning sleeves 8 coaxially, the limit pins 10 are slidably connected to the limit plate 12, a number of limit springs 11 are respectively sleeved on the outside of the number of limit pins 10, one end of the limit spring 11 is fixedly connected to the positioning plate 7, and the other end is fixedly connected to the limit plate 12, and a spherical head 9 is formed at the end of the positioning sleeve 8 away from the limit plate 12. When positioning the cable 1, these positioning sleeves 8 can adaptively adjust their positions under the action of the limit springs 11, and the spherical head 9 can make good contact with the surface of the cable 1 to form multiple contact points, realize flexible positioning, and adapt to cables 1 of different shapes and specifications. At the same time, this design avoids hard extrusion damage to the cable 1. Compared with the traditional clamp-type fastening device, the adaptability of the cable 1 will not be limited by the fixed shape of the clamp, and the cable 1 can be better positioned in all directions.

[0053] In order to drive the abutment frame 16 to reciprocate in the vertical direction, the following features are also specifically provided:

[0054] The positioning mechanism 6 also includes a central gear 23, two screw rods 20, two screw sleeves 21, two power gears 22, two lifting slides 19 and four limit guide rails 18. The central gear 23 is rotatably arranged at the upper end of the main frame 2 and meshes with the main gear plate 5 (refer to Figure 3 ), the two power gears 22 are rotatably arranged on both sides of the central gear 23 and mesh with the central gear 23, and the two screw sleeves 21 are respectively coaxially fixedly connected with the two power gears 22 (reference Figure 4), two screw rods 20 are respectively threadedly connected with two screw sleeves 21, two limiting guide rails 18 are respectively fixedly connected to the two sides of the positioning plate 7, the lifting slide 19 is fixedly connected to the lower end of the screw rod 20 and is slidably connected with the corresponding limiting guide rails 18, the two lifting slides 19 are respectively fixedly connected to the two clamping frames 16, and the main gear plate 5 is the input end of the positioning mechanism 6. When the main gear plate 5 rotates, the main gear plate 5 will drive the power gear 22 to rotate through the central gear 23, thereby rotating the screw sleeve 21, driving the screw rod 20 to move up and down, driving the lifting slide 19 to reciprocate in the vertical direction along the limiting guide rails 18, thereby accurately driving the clamping frame 16 to move in the vertical direction, and realizing the clamping and positioning of cables 1 at different heights. This process can adapt to the installation position requirements of cables 1 of different specifications, while it is difficult for traditional clamp-type fastening devices to flexibly adjust the clamping height.

[0055] In order to realize that when the lifting slide 19 moves toward the main frame 2, the two clamping frames 16 will move in the horizontal direction, thereby increasing the clamping force on the cable 1, the following features are specifically set:

[0056] The positioning mechanism 6 further includes two positioning racks 13, two positioning gears 14 and two push racks 15. The two positioning racks 13 are respectively arranged on both sides of the positioning plate 7 (refer to Figure 3 ), the two positioning gears 14 are rotatably connected to the two lifting slides 19, the two positioning gears 14 are respectively meshed with the two positioning racks 13, the two push racks 15 are respectively fixedly connected to the two clamping frames 16, and the two push racks 15 are respectively meshed with the two positioning gears 14. When the lifting slide 19 moves in the direction close to the main frame 2, the positioning gear 14 rotates along the positioning rack 13, and at the same time drives the push rack 15 meshed therewith, so that the two clamping frames 16 move in the horizontal direction, thereby increasing the clamping force on the cable 1. This design can automatically adjust the position of the clamping frame 16 according to the thickness of the cable 1, and realize adaptive clamping of cables 1 of different specifications.

[0057] In order to increase the friction between the abutment frame 16 and the cable 1, the following features are also specifically provided:

[0058] The upper end of the clamping frame 16 is formed with a plurality of anti-skid grooves 17 at equal intervals. When clamping the cable 1, the anti-skid grooves 17 increase the friction between the clamping frame 16 and the cable 1, effectively preventing the cable 1 from sliding during the fixing process, and improving the fixing stability.

[0059] In order to drive the turning frame 33 to turn over, so as to drive the buckling frame 35 to buckle on the outside of the cable 1 during the turning process, the following features are also specifically provided:

[0060] The flip mechanism 24 also includes a main bevel gear 25, a secondary bevel gear 26, a bevel gear frame 27, two main pulleys 28, two secondary pulleys 29, two power pulleys 30, two driving gears 31 and two flip gears 32. The bevel gear frame 27 is fixedly arranged at the upper end of the main frame 2 (refer to Figure 4 ), the main bevel gear 25 is coaxially fixedly connected to the main toothed disc 5, the main bevel gear 25 is rotatably connected to the bevel gear frame 27, the secondary bevel gear 26 is rotatably connected to the bevel gear frame 27 and meshes with the main bevel gear 25, the two main pulleys 28 are respectively rotatably arranged on both sides of the bevel gear frame 27 through the wheel seat and are coaxially fixedly connected to the main bevel gear 25, the two secondary pulleys 29 are respectively arranged below the two main pulleys 28 and are rotatably connected to both sides of the main frame 2, the two secondary pulleys 29 are respectively connected to the two main pulleys 28 through belt transmission, the two power pulleys 30 are respectively arranged on one side of the two secondary pulleys 29 close to the flip frame 33, the power pulley 30 is rotatably connected to the main frame 2, the two power pulleys 30 are respectively connected to the two secondary pulleys 29 through belt transmission, the two driving gears 31 are respectively coaxially fixedly connected to the two power pulleys 30, the two flip gears 32 are respectively coaxially fixedly connected to both sides of the flip frame 33, and the two flip gears 32 are respectively meshed with the two driving gears 31. When the main sprocket 5 rotates, the main sprocket 5 drives the main bevel gear 25 to rotate through the central gear 23, and the main bevel gear 25 drives the secondary bevel gear 26 to rotate. The secondary bevel gear 26 drives the driving gear 31 to rotate after being transmitted through the main pulley 28, the secondary pulley 29 and the power pulley 30 in turn. After the driving gear 31 rotates, it drives the flip frame 33 to flip through the flip gear 32, so as to drive the buckling frame 35 to buckle on the outside of the cable 1 during the flipping process. The flip frame 33 drives the buckling frame 35 to flip and buckle from the top or side, which can wrap the cable 1 from more angles, and greatly enhances the wrapping of the cable 1 compared to the traditional single-sided or simple surrounding fixing method. This allows the cable 1 to be more firmly fixed when it is pulled or vibrated by external forces in all directions, effectively reducing the displacement or loosening of the cable 1 caused by uneven force, and ensuring the long-term stable operation of the cable 1 in a complex environment.

[0061] In order to increase the friction between the buckling frame 35 and the cable 1, the following features are also specifically provided:

[0062] A plurality of protective flanges 36 are formed in an array at equal intervals on one side of the buckling frame 35. When the buckling frame 35 buckles the cable 1, the protective flange 36 increases the friction between the cable 1 and the buckling frame 35 to prevent relative sliding between the cable 1 and the buckling frame 35.

[0063] In order to adjust the relative position between the buckling frame 35 and the flip frame 33, and ensure that the flip frame 33 can be buckled on the cable 1 after flipping, so as to clamp cables 1 of different specifications, the following features are specifically provided:

[0064] The turning mechanism 24 further includes a limit support 39, a limit push plate 41, a fine-tuning bolt 42 and two limit bolts 40. The limit support 39 is fixedly connected to the upper end of the turning frame 33 (refer to Figure 6 ), the limit push plate 41 is slidably connected to the limit support 39, two limit bolts 40 are fixedly connected to one end of the limit push plate 41 close to the buckling frame 35, and the fine-tuning bolt 42 is arranged on the side of the limit push plate 41 away from the limit bolt 40. One end of the fine-tuning bolt 42 is rotatably connected to the limit push plate 41, and the other end is threadedly connected to the limit support 39. The buckling frame 35 is close to the side of the limit support 39 and is formed with a plurality of limit holes 38 (reference Figure 1 ), the limit bolt 40 will be inserted into the corresponding limit hole 38 when it moves. When it is necessary to clamp cables 1 of different specifications, the operator rotates the fine-tuning bolt 42 to push the limit push plate 41 to move, and then adjust the position of the limit bolt 40 to insert it into different limit holes 38, thereby adjusting the relative position between the buckling frame 35 and the flip frame 33 to ensure that the flip frame 33 can be buckled on the cable 1 after flipping. This fine-tuning design enables the device to adapt to cables 1 of various specifications and achieve flexible adjustment.

[0065] In order to limit the movement of the buckling frame 35, the following features are also specifically provided:

[0066] The flip mechanism 24 further includes a positioning slider 34, which is fixedly connected to the flip frame 33. The two sides of the pressing frame 35 are formed with limited sliding grooves 37 (refer to Figure 7 ), the limiting slide groove 37 is slidably connected with the positioning slider 34. During the movement of the buckling frame 35, the positioning slider 34 slides along the limiting slide groove 37 to limit the movement of the buckling frame 35, thereby ensuring the stability and accuracy of the movement of the buckling frame 35, ensuring that it can be accurately buckled on the cable 1, and avoiding deviation and the like.

[0067] The working principle of the device is that when the cable 1 needs to be fixed, the operator first buckles the main frame 2 on the cable 1, and then the operator rotates the turntable 3. The rotation of the turntable 3 drives the main gear 4 coaxially connected to it to rotate, and the main gear 4 meshes with the main toothed disc 5, thereby driving the main toothed disc 5 to rotate. When the main toothed disc 5 rotates, on the one hand, it drives the central gear 23 to rotate by meshing with the central gear 23, and the power gears 22 on both sides of the central gear 23 rotate accordingly. The power gear 22 drives the screw sleeve 21 coaxially connected to it to rotate, so that the screw 20 threadedly connected to the screw sleeve 21 moves along its own axis, and then the lifting slide 19 connected to the lower end of the screw 20 moves in the vertical direction along the limiting guide rail 18, driving the clamping frame 16 fixed to it to move in the vertical direction. At the same time, during the movement of the lifting slide 19, the positioning gear 14 connected to it rotates along the positioning racks 13 on both sides of the positioning plate 7, and the positioning gear 14 drives the push rack 15 meshed with it to move the two abutting frames 16 in the horizontal direction, thereby abutting the cable 1. The positioning sleeve 8 in the positioning mechanism 6 adjusts its position adaptively under the action of the limit spring 11, and its spherical head 9 contacts the surface of the cable 1 to form multiple contact points to achieve flexible positioning.

[0068] On the other hand, the main toothed disc 5 drives the main bevel gear 25 to rotate, and the main bevel gear 25 drives the secondary bevel gear 26 to rotate, and then the belt transmission of the main pulley 28, the secondary pulley 29 and the power pulley 30 causes the driving gear 31 coaxially connected to the power pulley 30 to rotate, and the driving gear 31 drives the turning gears 32 on both sides of the turning frame 33 to rotate, and then drives the turning frame 33 to turn over. Under the limiting action of the positioning slider 34 and the limiting slide groove 37, the buckling frame 35 on the turning frame 33 turns over with the turning frame 33 and finally buckles on the cable 1. The protective flange 36 on the buckling frame 35 and the anti-slip groove 17 on the abutting frame 16 increase the friction between the cable 1 respectively.

[0069] In this process, if encountering cables 1 of different specifications, the operator can adjust the position of the limit push plate 41 by rotating the fine-tuning bolt 42, so that the limit bolt 40 is inserted into different limit holes 38 of the buckling frame 35, and the relative position between the buckling frame 35 and the flip frame 33 is adjusted to achieve adaptive clamping and positioning of cables 1 of different specifications. Compared with the traditional clamp-type fastening device, this device can perform all-round and adaptive clamping and positioning of cables 1 of any specifications through the coordinated work of multiple mechanisms, avoiding damage to the cables 1, and making the installation process more flexible, efficient and accurate.

[0070] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
