Description

Technical Field

[0001] This utility model relates to the field of cable clamp technology, and in particular to a cable fixing clamp device. Background Technology

[0002] A cable is a component that connects two devices to transmit electrical signals. It is formed by bonding, twisting, or braiding two or more conductors together. Depending on the application and environmental requirements, there are various types and structures. The main functions of a cable are to transmit electrical energy, electrical signals, and to achieve electromagnetic energy conversion. Cables used in stationary environments are widely used in electrical connections in industrial automation, electromechanical equipment, machine tools and other mechanical equipment, computer systems, logistics transmission systems, and production line control systems for signal and power transmission. By securely fixing, holding, and properly supporting the cable, the mechanical load caused by the cable's own weight can be reduced, thereby reducing the mechanical load applied to the cable termination.

[0003] Existing technology CN218449243U discloses an insulating clamp for cable fixing, including a clamp mounting plate and a spring. Mounting screws are installed on both the left and right sides of the interior of the clamp mounting plate, and a clamp is located at the upper center of the mounting plate. Two springs are located on the inner left and right sides of the clamp. A compression block is located inside the spring, and an insulating block is located at the upper end of the compression block. A second clamp is located at the upper end of the clamp. Compared with existing insulating clamps for cable fixing, this insulating clamp can fully fix the cable according to its size, avoiding insecure fixing. It can also prevent cable damage and avoid the clamp breaking due to cable tension during clamping, thus affecting the clamp's use. Furthermore, the clamps provide insulation for the cable during use, improving the clamp's applicability.

[0004] However, the above-mentioned cable fixing insulating clamps have the following problems: fixing the cable by a single screw has a low fixing effect, and the slow rotation of the screw cannot achieve a fast fixing effect. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a cable fixing clamp device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cable fixing clamp device, comprising: a first clamp and a second clamp disposed below the first clamp, and a plurality of fixing components disposed on the first clamp;

[0007] The fixing components include: a plurality of first telescopic rods connected to the top of the first clamp, a plurality of first springs disposed on the outer surface of the plurality of first telescopic rods, and an insulating fixing block fixedly connected to the bottom of the plurality of first telescopic rods;

[0008] A plurality of first sliding rods are fixedly installed on the inner wall of the upper half of the first telescopic rod. Two clamping plates are connected to the two ends of the plurality of first sliding rods. A plurality of clamping blocks are fixed on the outer side of the two clamping plates. A plurality of second telescopic rods are slidably connected inside the plurality of clamping blocks. The two ends of the second telescopic rods are set in the plurality of clamping blocks on the same horizontal plane. A plurality of second springs are installed on the outer side of the plurality of second telescopic rods. The two ends of the plurality of second springs are fixed on the inner sidewalls of the two clamping plates.

[0009] In a preferred embodiment of this utility model, a plurality of fixing rods are provided on the top outer side wall of the first clamp, and a plurality of locking blocks are provided in the plurality of fixing rods at equal intervals. The distance between a plurality of adjacent locking blocks is slightly greater than the height of the clamping block, and the plurality of clamping blocks are connected in the gap between the plurality of locking blocks.

[0010] In a preferred embodiment of the present invention, a slide rail is provided at the top of the plurality of fixed rods, the width of the slide rail is equal to the width of the plurality of clamps, and the top of the plurality of clamps is disposed within the slide rail.

[0011] In a preferred embodiment of the present invention, the plurality of fixing components are divided into three groups, and the three groups of fixing components are circumferentially distributed on the first wire clamp triangle.

[0012] In a preferred embodiment of this utility model, a plurality of pressure-bearing blocks are provided inside the second clamp, a plurality of third telescopic rods are fixedly connected to the bottom of the plurality of pressure-bearing blocks, and a plurality of third springs are sleeved on the outside of the plurality of third telescopic rods.

[0013] In a preferred embodiment of this utility model, the bottom of several third telescopic rods is fixed to the inner wall of the second wire clamp triangle, and the two ends of several third springs are fixed to the bottom of several pressure blocks and the inner wall of the second wire clamp triangle.

[0014] In a preferred embodiment of this utility model, a plurality of the first springs are respectively fixed on the top of a plurality of the insulating fixing blocks and on the inner wall of the top of the first clamp.

[0015] In a preferred embodiment of this utility model, the bottom of the second wire clamp is fixedly mounted on a fixed base, and mounting screws are provided on the left and right sides of the fixed base.

[0016] In a preferred embodiment of this utility model, both the first and second wire clamps have through holes on their exteriors, and bolts are installed in both the upper and lower parts of the through holes.

[0017] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0018] (1) This utility model achieves quick installation and disassembly of the wire clamp by locking block. The cable is placed in the first wire clamp and the second wire clamp, the clamp plate is clamped, the locking block retracts along the second telescopic rod, and the first telescopic rod is pushed down. When the insulating fixing block is tightly fixed on the cable, the clamp plate is released, and the locking block extends under the elastic potential energy of the second spring and is locked in the gap of the locking block. Multiple fixing components are performed in sequence, so that the insulating fixing block quickly fixes the cable. The reverse operation quickly loosens the cable. Compared with the prior art, this device eliminates the screwing step and can quickly maintain stable clamping under different cable sizes, reducing time costs.

[0019] (2) By setting a multi-point support structure on the clamping surface, the pressure on the cable can be evenly distributed, avoiding local stress concentration. The weight and pressure of the cable are distributed by multiple third springs and third telescopic rods, and the support points are expanded into multi-point elastic supports with surface contact. This directly reduces the risk of indentation or damage to the cable outer sheath caused by excessive pressure at a single point, and further improves the structural integrity and fatigue life of the cable in long-term operation.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] like Figures 1-3 As shown, a cable fixing clamp device includes: a first clamp 1 and a second clamp 2 disposed below the first clamp 1, and a plurality of fixing components disposed on the first clamp 1.

[0027] In this invention, several fixing components include: several first telescopic rods 3 connected to the top of the first clamp 1, several first springs 4 disposed on the outer surface of the first telescopic rods 3, and insulating fixing blocks 5 fixedly connected to the bottom of the first telescopic rods 3; the first springs 4 are respectively fixed to the top of the insulating fixing blocks 5 and the inner wall of the top of the first clamp 1. After the cable is placed between the first clamp 1 and the second clamp 2, the first clamp 1 is pressed down, the first telescopic rods 3 are compressed and shortened in length; the first springs 4 are simultaneously compressed, storing elastic potential energy; the insulating fixing blocks 5 move down with the telescopic rods and gradually fit against the cable surface. The three sets of fixing components are circumferentially distributed to ensure that the cable is evenly surrounded on three sides, avoiding excessive tightness on one side due to the ellipticity or bending of the cable. The continuous elastic force of the first springs 4 keeps the insulating fixing blocks 5 under constant pressure on the cable, which can both clamp the cable and avoid rigid compression damage to the outer sheath. When the cable vibrates due to wind or short-circuit electrodynamics, the first springs 4 absorb vibration energy through elastic deformation, reducing fretting wear between the cable and the clamps. Pulling up the first clamp 1 releases the potential energy of the first spring 4, pushing the telescopic rod to extend, and the insulating fixing block 5 automatically detaches from the cable.

[0028] In this utility model, a plurality of first sliding rods 6 are fixedly arranged on the inner wall of the upper half of the first telescopic rod 3. Two clamping plates 7 are connected to both ends of the plurality of first sliding rods 6. A plurality of clamping blocks 8 are fixed on the outer side of both clamping plates 7. A plurality of second telescopic rods 9 are slidably connected inside the plurality of clamping blocks 8. The two ends of the second telescopic rods 9 are arranged in the clamping blocks 8 on the same horizontal plane. A plurality of second springs 10 are arranged on the outer side of the plurality of second telescopic rods 9. The two ends of the plurality of second springs 10 are fixed on the inner side wall of the two clamping plates 7. The two clamping plates 7 are opened by the second spring 10, and the clamping block 8 is in an extended state, directly facing the gap of the locking block 12 on the fixing rod 11. After the cable is inserted into the first and second clamps 2, the operator squeezes the two clamping plates 7 inward. The clamping plates 7 slide along the first sliding rod 6, the second spring 10 is compressed, and the clamping block 8 retracts inward, disengaging from the gap of the locking block 12. The entire fixing assembly moves downward, adhering to and pressing the cable. After the cable is pressed, the operator releases the operator, the second spring 10 returns to its original position, the clamping plates 7 are pushed open again, the clamping block 8 extends outward and re-engages in the gap of the locking block 12, forming a one-way mechanical lock. The first clamp 1 can no longer spring back upward, and the cable is clamped evenly and continuously at three points. When the clamping plates 7 are squeezed again, the clamping block 8 retracts inward and disengages from the locking block 12. The first spring 4 then springs the first clamp 1 up as a whole, completing the cable release.

[0029] In this invention, a plurality of fixing rods 11 are provided with slide rails 13 at their tops. The width of the slide rails 13 is equal to the width of a plurality of clamping plates 7, and the tops of the clamping plates 7 are disposed within the slide rails 13. The tops of the clamping plates 7 are directly inserted into the slide rails 13, with their width fitting the slide rails 13 with zero clearance. The clamping plates 7 are clamped by the slide rails 13 and can only slide horizontally, without tilting, lifting, or falling out. When the clamping plates 7 are squeezed or released, the slide rails 13 guide the clamping plates 7.

[0030] In this invention, a plurality of pressure-bearing blocks 14 are provided inside the second clamp 2. A plurality of third telescopic rods 15 are fixedly connected to the bottom of each pressure-bearing block 14, and a plurality of third springs 16 are sleeved on the outside of each third telescopic rod 15. The bottoms of the third telescopic rods 15 are fixed to the inner wall of the triangular section of the second clamp 2, and the two ends of the third springs 16 are fixed to the bottom of the pressure-bearing blocks 14 and the inner wall of the triangular section of the second clamp 2. When the cable is placed into the second clamp 2, it rests on the pressure-bearing blocks 14. The pressure-bearing blocks 14 have an arc-shaped composite surface, increasing the contact area and reducing local pressure. The cable's own weight causes the pressure-bearing blocks 14 to move downwards, compressing the third telescopic rods 15, guiding and restricting their direction of movement. The third springs 16 are simultaneously compressed, converting kinetic energy into elastic potential energy, thus achieving buffering.

[0031] In this invention, the bottom of the second wire clamp 2 is fixedly mounted on the fixing base 17. Mounting screws 18 are installed on both sides of the fixing base 17. Both the first wire clamp 1 and the second wire clamp 2 have through holes on their exteriors, and bolts 19 are installed through these holes vertically. The fixing base 17 is attached to the mounting surface, and the mounting screws 18 on both sides are tightened.

[0032] When using this utility model, loosen the bolt 19 inside the through hole, flip the first clamp 1 upwards, place the cable flat on the three pressure blocks 14 of the second clamp 2, close the first clamp 1, after the insulating fixing block 5 contacts the cable, the first spring 4 continues to compress, the operator squeezes the two clamp plates 7 inwards, the clamp plates 7 slide along the first sliding rod 6, the second spring 10 is compressed, the clamping block 8 retracts inwards, disengages from the gap of the locking block 12, the cable is clamped and then released, the second spring 10 returns to its original position, the clamp plates 7 are pushed open again, the clamping block 8 extends outwards and re-clamps into the gap of the locking block 12, forming a one-way mechanical lock, the first clamp 1 can no longer spring back upwards, the cable is clamped evenly and continuously at three points, tighten the bolt 19 inside the through hole.

[0033] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
