[0026] The cable fixing device provided by the present invention will be explained and described in detail below with reference to the accompanying drawings.

[0027] This embodiment specifically discloses a cable fixing device, such as... Figure 1 As shown, it includes an H-shaped cable fixing card 1, an H-shaped pressing mold 2, and a driving mechanism 3. The H-shaped cable fixing card 1 and the H-shaped pressing mold 2 are detachably connected. The driving mechanism 3 is used to drive the H-shaped pressing mold 2 to press the H-shaped cable fixing card 1. The H-shaped pressing mold 2 is used to press the four sides of the H-shaped cable fixing card 1 to bend into a claw shape away from the side of the H-shaped pressing mold 2.

[0028] When using the cable fastener of this embodiment, the H-type cable fastening card 1 and the H-type pressing mold 2 are detachably connected. The H-type cable fastening card 1 can be set to different specifications and sizes, and can be selected according to the specifications of the cable 7 to be fastened. When fastening the cable 7, select an H-type cable fastening card 1 of appropriate size and specifications and install it on the H-type pressing mold 2. The side of the H-type cable fastening card away from the H-type pressing mold 2 contacts the cable 7. Under normal circumstances, the cable 7 contacts the horizontal edge of the middle of the H-type cable fastening card 1, and the length direction of the cable 7 is basically parallel to the four sides of the H-type cable fastening card. The driving mechanism 3 drives the H-type pressing mold 2 to press and bend the four sides of the H-type cable fastening card 1 into a claw shape and hold it on the cable bracket 8. The cable 7 is held between the H-type cable fastening card and the cable bracket, thereby fixing the cable 7 on the cable bracket 8. The H-type cable fastening card 1 is also held tightly on the cable bracket 8. Remove the H-type pressing mold 2 to complete the fastening of the cable 7.

[0029] like Figure 1 and 2 As shown, the H-shaped pressing mold 2 includes an H-shaped base plate 21, a primary pressing plate 22, and a secondary pressing plate 23. The four corners of the H-shaped base plate 21 are sequentially connected to the secondary pressing plate 23 and the primary pressing plate 22 from the inside out. The inner side of the secondary pressing plate 23 is rotatably connected to the H-shaped base plate 21, and the outer side of the secondary pressing plate 23 is rotatably connected to the inner side of the primary pressing plate 22. In this embodiment, the primary pressing plate 22 and the secondary pressing plate 23 are rotatably connected via a hinge or a matching rotating shaft sleeve. Through the pressing action of the H-shaped pressing mold 2, the primary pressing plate 22 can rotate relative to the secondary pressing plate 23 at a certain angle, thereby pressing and bending the H-shaped cable fixing card 1 at the contact point with the primary pressing plate 22. When rotation is achieved using a rotating hinge, the primary pressing plate is welded to one of the hinge's leaves, and the secondary pressing plate is welded to the other leaf of the hinge. When rotation is achieved using a rotating shaft sleeve, one of the primary and secondary pressing plates is welded to the rotating shaft, and the other is welded to the outer wall of the sleeve. The sleeve is fitted onto the rotating shaft to achieve rotation. Similarly, the secondary pressing plate 23 is rotatably connected to the H-shaped base plate 21 via a rotating hinge or a matching rotating shaft sleeve. Through the pressing of the H-shaped pressing mold 2, the secondary pressing plate 23 can rotate relative to the H-shaped base plate 21 at a certain angle, thereby pressing and bending the H-shaped cable fixing card 1 at the contact point with the secondary pressing plate 23.

[0030] like Figure 2As shown, the drive mechanism 3 includes a primary hydraulic rod 31, a secondary hydraulic rod 32, and a drive connector 33. The primary hydraulic rod 31 is used to drive the primary pressing plate 22 to rotate away from the primary hydraulic rod 31. In this embodiment, a total of four primary hydraulic rods 31 and four secondary hydraulic rods 32 are provided. Each primary pressing plate 22 is provided with one primary hydraulic rod 31. The telescopic end of the primary hydraulic rod 31 is connected to the primary pressing plate 22 through the drive connector 33. The secondary hydraulic rod 32 is used to drive the secondary pressing plate 23 to rotate away from the secondary hydraulic rod 32. Each secondary pressing plate 23 is provided with one secondary hydraulic rod 32. The telescopic end of the secondary hydraulic rod 32 is connected to the secondary pressing plate 23 through the drive connector 33.

[0031] like Figure 2 As shown, the drive connector 33 includes a spring 331 and a corner piece 332. One end of the spring 331 is fixedly connected to the telescopic end of the hydraulic rod, and the other end of the spring 331 is fixedly connected to one outer side of the corner piece 332. The other outer side of the corner piece 332 is fixedly connected to the pressing plate corresponding to the hydraulic rod. The angles of the corner pieces connected to the primary pressing plate and the secondary pressing plate can be the same or different. In this embodiment, the corner piece 332 is welded to the pressing plate, and the corner pieces 332 connected to both the primary and secondary pressing plates are right angles.

[0032] like Figure 3 As shown, taking the rotation of the primary pressing plate 22 as an example, one outer side of the corner piece 332 is welded to the primary pressing plate 22, and the other outer side of the corner piece 332 is welded to the spring 331. The other end of the spring 331 is welded to the primary hydraulic rod 31. In the initial state, the primary pressing plate 22 and the secondary pressing plate 23 are on the same straight line, and the telescopic end of the primary hydraulic rod 31 is in the retracted state. After the primary hydraulic rod 31 is activated, the telescopic end of the primary hydraulic rod 31 extends, pushing the spring 331 and the corner piece 332 to move. Due to the rotation restriction between the primary pressing plate 22 and the secondary pressing plate 23, the corner piece 332 can only rotate and cannot move outward in parallel. Therefore, the primary pressing plate 22 is rotated away from the primary hydraulic rod 31, forming a certain angle with the secondary pressing plate 23. Moreover, the spring 331 bends due to the interaction of forces, and the primary pressing plate 22 presses and bends the H-shaped cable fixing card 1 at this position at a certain angle. After being pressed to the appropriate angle, the telescopic end of the first-stage hydraulic rod 31 retracts, the spring 331 pulls the corner piece 332 to move back to the initial state, and the last-stage pressing plate 22 returns to the initial state.

[0033] The pressing process of the secondary pressing plate 23 uses the same method. The bent H-shaped cable fixing card 1 is in the following state: Figure 5 As shown.

[0034] The cable fastener in this embodiment also includes a control switch 5 and a controller. The control switch 5 is electrically connected to the controller, and the controller is electrically connected to the primary hydraulic rod 31 and the secondary hydraulic rod 32. The primary hydraulic rod and the secondary hydraulic rod 32 can be controlled separately by operating the control switch 5. Typically, the primary hydraulic rod 31 is controlled first to press the H-shaped cable fixing clip 1, and then the secondary hydraulic rod 32 is controlled to press the H-shaped cable fixing clip 1.

[0035] The control switch 5 is a push-button type. Button N=1 is used to control the action of the first-stage hydraulic rod 31, and button N=2 is used to control the action of the second-stage hydraulic rod 32.

[0036] The cable fastener in this embodiment also includes a handheld housing 4, a control switch 5, and a controller fixed on the handheld housing 4. The control switch 5 is embedded in the handheld housing 4, making the entire cable fastener small in size and easy to operate, allowing for handheld operation. The H-type pressing mold 2 and the H-type cable fixing clip 1 are detachably connected to the handheld housing 4, facilitating the replacement of the H-type pressing mold 2 and the H-type cable fixing clip 1.

[0037] like Figure 1 As shown, a magnetic suction device 6 is also fixed on the handheld housing 4. The H-shaped cable fixing card 1 and the H-shaped pressing mold 2 are magnetically fixed to the handheld housing 4 by the magnetic suction device 6, which facilitates the installation and removal of the H-shaped cable fixing card 1 and the H-shaped pressing mold 2. In this embodiment, the magnetic suction device can be a magnet, and the H-shaped cable fixing card 1 and the H-shaped pressing mold 2 are made of iron.

[0038] The method for fixing the cable 7 to the cable bracket 8 using the cable fastener in this embodiment is as follows: After the wires and cables are laid, select an H-shaped pressing mold 2 and an H-shaped cable fixing card 1 of appropriate size. Attach the H-shaped pressing mold 2 to the handheld housing 4 through the magnetic attraction point of the magnetic attraction device 6. The front end of the magnetic attraction device 6 is exposed above the H-shaped pressing mold 2. Attach the H-shaped cable fixing card 1 to the handheld housing through the magnetic attraction point of the magnetic attraction device 6 at the front end of the H-shaped pressing mold 2, placing it at the front end of the H-shaped pressing mold 2. The cable fastener is moved to the cable 7 fixing point. The worker holds cable 7 with one hand, placing it on the cable bracket's fixed position, and operates control switch 5 with the other hand. When the button for N=1 is pressed, the output value is N=1, triggering action one: the primary hydraulic rod 31 extends, pushing the corresponding corner piece 332. This causes the primary pressing plate 22 to press and bend the H-shaped cable fixing clip 1. When the button for N=1 is released again, because the corner piece 332 and the primary hydraulic rod 31 are welded together by spring 331, the primary hydraulic rod 31 returns to its initial state, and the corner piece 332... It also returns to the initial state; when the button with N=2 is pressed, the output value is N=2, and the second action is performed to control the secondary hydraulic rod 32 to move. The telescopic end of the secondary hydraulic rod 32 extends and pushes the corresponding corner piece 332, so that the secondary pressing plate 23 presses the H-type cable fixing card 1 and bends it inward again to fit against the support arm of the cable bracket 8. When the secondary pressing plate 23 rotates, the primary pressing plate 22 will also rotate with the secondary pressing plate 23 through the deformation of the spring 331 connected to the primary pressing plate 22, without affecting the rotation and pressing of the secondary pressing plate 23. After the button with N=2 is released, since the corner piece 332 and the secondary hydraulic rod 32 are welded by the spring 331, the secondary hydraulic rod 32 returns to the initial state, the corner piece 332 also returns to the initial state, the secondary pressing plate 23 retracts, the H-type cable fixing card 1 is fixed to the cable bracket 8, and the cable 7 is fixed. The effect after fixing is as follows. Figure 6 As shown.

[0039] Each time you bend the cable, the rotation angle of the first and second pressing plates, i.e. the final bend angle of the H-type cable fixing card, is adjusted according to the diameter of the cable to be fixed. Just make sure that the H-type cable fixing card can be clamped on the cable bracket and the cable is firmly fixed on the cable bracket.

[0040] The pressure plate is rotating, which can eliminate the squeezing damage to the cable during the bending process of the H-type cable fixing card. At the same time, the pre-customized size of the H-type cable fixing card will not close after bending on all four sides, eliminating the eddy current phenomenon caused by the wires and cables forming a closed loop due to fixing.

[0041] The cable fastener in this embodiment is a handheld, rechargeable type, small in size, and can be operated by one person. The H-shaped pressing mold 2 and the H-shaped cable fixing card 1 can be replaced with different specifications and sizes to match wires and cables of different diameters. The operation method is simple. It is mainly used to fix wires and cables that need to be fixed when laid through cable brackets, cable shaft climbing frames, etc. The matched H-shaped cable fixing card 1 is used to rigidly fix the cable after it has been laid, ensuring the fixation strength and appearance quality.

[0042] This invention improves work efficiency. Practical verification shows it is 8-10 times faster than traditional manual wire and cable fixing, significantly reducing worker workload. It uses H-shaped pressing molds 2 and H-shaped cable fixing cards 1 of different sizes and specifications to match different cable bracket models, offering strong applicability and convenient fixing in both horizontal and vertical orientations. The customized design of the H-shaped cable fixing card 1 ensures a uniform fixing method at all points, resulting in a high-quality appearance. Its special structural design allows for easy tightening and fixing of the card, providing strong clamping force. Furthermore, the H-shaped cable fixing card 1 does not form a closed loop after bending, eliminating eddy current phenomena caused by the formation of closed loops in the wires and cables during fixing.
