Description

Technical Field

[0001] This invention relates to the field of cable technology, and more specifically, to a cable with shock-resistant function. Background Technology

[0002] In cable applications, especially in complex environments or under dynamic conditions, cables are often affected by vibration. This vibration can not only cause internal conductors to break or make poor connections, but also affect the transmission of electrical signals. Traditional cable designs often lack effective shock-resistant mechanisms and cannot effectively cope with the challenges posed by vibration.

[0003] In existing technologies, shock-absorbing elastic materials are often filled between the cable core and the protective shell to achieve a shock-absorbing effect. However, this method cannot effectively absorb vibrations along the cable axis, nor can the shock-absorbing effect be adjusted according to actual operating conditions. Furthermore, the strong vibrations during transportation can damage the shock-absorbing filler, thus affecting the actual shock-absorbing effect. Therefore, developing a cable with excellent shock-absorbing properties has become an urgent problem to be solved in the current cable technology field. Summary of the Invention

[0007] As a preferred embodiment of the present invention, the inner wall of the protective shell and the cylindrical portion are fixedly provided with inner retaining rings, and a connecting block is provided on the outer side of the inner retaining ring.

The inner rotating groove, the outer rotating groove, and the annular hole overlap. An outer rotating ring is rotatably provided on the outer retaining ring.

An inner rotating ring is provided on the connecting block, and the inner rotating ring is rotatably provided on the inner side wall of the inner retaining ring.

[0008] As a preferred embodiment of the present invention, the outer rotating ring is uniformly provided with concave grooves on its outer side to facilitate twisting.

[0009] As a preferred embodiment of the present invention, the inner rotating ring is symmetrically provided with two unlocking push blocks for driving the round pin, and the side of the unlocking push block facing the round pin is composed of an inclined surface and a flat surface.

[0010] As a preferred embodiment of the present invention, an insert block is fixedly provided on the cylinder and located next to the rotating ring. The insert block has an insertion hole, and the inner rotating ring is provided with a double-headed circular insert rod for insertion into the insertion hole.

[0011] As a preferred embodiment of the present invention, the side of the insert block is provided with a through hole that communicates with the insertion hole, and a pin is slidably provided in the through hole.

[0013] The advantages of this invention compared to the prior art are:

[0014] (1) The present invention uses a damping system composed of a groove, a slider, a damping spring, and a connecting rod to effectively absorb and disperse vibration energy, making the amplitude of the cable core smaller than that of the protective shell, thus significantly reducing the impact of vibration on the cable core. The ball-head hinge design ensures that the damping unit has a shock-absorbing effect when the protective shell vibrates in any direction, improving the stability and durability of the cable.

[0015] (2) By rotating the circular ring and then pushing the top block to move through the arc-shaped triangular block, the position of the top block on the slide can be adjusted, thus adjusting the tightness of the damping spring and adjusting the damping effect of the damping unit according to actual needs, thereby improving the adaptability and flexibility of the cable.

[0016] (3) During transportation, the invention can insert one end of the double-ended round plug into the plug hole of the plug block, and at the same time the plug pin is automatically inserted into the limiting hole, so as to lock the cylinder and the cable core, prevent the cable from being damaged by strong shaking during transportation, and facilitate cable installation and debugging.

[0017] (4) The present invention provides a center groove, a locking groove and a dial on the dial plate, and a pointer on the outer rotating ring. By pointing the pointer to different positions on the dial plate, the shock absorption unit can be put into working state or locked state, and the tightness of the shock absorption spring can be accurately adjusted.

Detailed Implementation

[0031] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0032] Example: Please refer to Figure 1-12 The present invention provides the following technical solution: a cable with shock absorption function, comprising a cable core 1, a protective shell 2 covering the cable core 1, and multiple sets of shock-absorbing units between the cable core 1 and the protective shell 2. Each set of shock-absorbing units includes two cylinders 3 fixedly disposed outside the cable core 1. Four grooves 4 are evenly provided on opposite sides of the two cylinders 3. A slider 5 and a top block 6 are slidably disposed on the grooves 4 in sequence, and a shock-absorbing spring 7 is connected between the slider 5 and the top block 6. The four grooves 4 on the two cylinders 3 correspond one-to-one. A block 9 is provided between each of the two corresponding grooves 4, and the block 9 is disposed on the inner side wall of the protective shell 2. A connecting rod 8 is provided between the slider 5 and the corresponding block 9, and the two ends of the connecting rod 8 are respectively hinged to the ball heads of the corresponding slider 5 and block 9. A push rod 10 is provided on the side of the top block 6.

[0033] Specifically, the protective shell 2 is fixedly mounted on the cable bracket. Frictional damping is generated between the slider 5 and the groove 4, which, together with the damping spring 7, constitutes a shock absorption system. When the cable bracket vibrates in the cross-sectional direction of the protective shell 2, the cable bracket vibrates synchronously with the protective shell 2, and the cable core 1 sways in the cross-section of the protective shell 2. When the cable core 1 is close to the side of the protective shell 2, the slider 5 moves along the groove 4 away from the block 9; when the cable core 1 is away from the side of the protective shell 2, the slider 5 moves along the groove 4 towards the block 9. Therefore, the amplitude of the cable core 1 is smaller than the amplitude of the protective shell 2, giving the cable core 1 a shock absorption effect. Since the two ends of the connecting rod 8 are hinged to the slider 5 and the block 9 respectively in a ball-head manner, the shock absorption unit has a shock absorption effect when the cable bracket vibrates in any direction of the protective shell 2. When the cable support vibrates along the axial direction of the protective shell 2, the protective shell 2 vibrates synchronously along its axial direction, and all the sliders 5 slide synchronously in the corresponding grooves 4, so that the amplitude of the cable core 1 is also smaller than the amplitude of the protective shell 2, thus giving the cable core 1 a shockproof effect.

[0034] A rotating ring 11 is provided on the cylinder 3, and four arc-shaped triangular blocks 12 are provided on the rotating ring 11 to drive the four push rods 10 respectively.

[0035] Specifically, rotating the circular ring 11 on the cylinder 3 drives the push rod 10 to move, that is, the push rod 10 moves the top block 6 on the slide groove 4. Adjusting the distance between the top block 6 and the slider 5 can adjust the tension of the damping spring 7, thus adjusting the damping effect of the damping unit. When the damping spring 7 has been used for too long, its elasticity weakens. Rotating the circular ring 11 can also strengthen the elasticity of the damping spring 7.

[0036] A slide block 13 is provided on the side of the circular ring 11. A slide rod 14 is slidably provided on the slide block 13 along the radial direction of the cable core 1. A base plate 15 is provided at the bottom of the slide rod 14. A spring 16 is sleeved on the outside of the slide rod 14. The two ends of the spring 16 are connected to the base plate 15 and the slide block 13 respectively. A locking block 17 is provided at the bottom of the base plate 15. A round pin 18 is provided on the side of the base plate 15. A locking plate 19 is fixed on the cylinder 3. The locking plate 19 has multiple locking grooves 1901 for the locking block 17 to be inserted.

[0037] Specifically, spring 16 provides elastic force, causing the locking block 17 on the base plate 15 to insert into the locking groove 1901, so the rotating ring 11 is locked on the cylinder 3 and no longer rotates.

[0038] The inner wall of the protective shell 2 and the cylindrical part 3 are fixedly provided with an inner retaining ring 20. A retaining block 21 is provided on the outer side of the inner retaining ring 20. The protective shell 2 is provided with an annular hole 201 for the retaining block 21 to pass through. An outer retaining ring 22 is provided on the outer side of the retaining block 21. The inner retaining ring 20 and the outer retaining ring 22 clamp the protective shell 2. The inner retaining ring 20 is provided with an inner rotating groove 2001. The outer retaining ring 22 is provided with an outer rotating groove 2201. The protective shell 2 is provided with an annular hole 202. The inner rotating groove 2001, the outer rotating groove 2201 and the annular hole 202 overlap.

[0039] An outer rotating ring 23 is provided on the outside of the outer fixed ring 22. A rotating block 24 is provided on the inner side wall of the outer rotating ring 23. The rotating block 24 passes through the inner rotating groove 2001, the outer rotating groove 2201 and the second annular hole 202. An inner rotating ring 25 is provided on the rotating block 24, and the inner rotating ring 25 is rotatably disposed on the inner side wall of the inner fixed ring 20.

[0040] Specifically, rotating the outer rotating ring 23 transmits power through the rotating connecting block 24, which in turn drives the inner rotating ring 25 to rotate on the inner side wall of the inner solid ring 20. The outer rotating ring 23 and the outer solid ring 22, as well as the inner rotating ring 25 and the inner solid ring 20, are tightly sealed.

[0041] The outer rotating ring 23 is provided with uniform grooves on its outer side to facilitate twisting, so that the outer rotating ring 23 can be manually twisted to rotate on the outer fixed ring 22.

[0042] Two unlocking push blocks 26 for driving the circular pin 18 are symmetrically provided on the inner rotating ring 25. The side of the unlocking push block 26 facing the circular pin 18 is composed of an inclined surface and a flat surface.

[0043] Specifically, the inner rotating ring 25 rotates with the round pin 18. The inclined surface of the unlocking push block 26 first contacts the round pin 18, and the inclined surface of the unlocking push block 26 drives the round pin 18 to move away from the locking plate 19. That is, the round pin 18, along with the base plate 15, the slide rod 14, and the locking block 17, moves along the slide block 13 away from the locking plate 19. The spring 16 is compressed, and the locking block 17 disengages from the locking groove 1901, meaning that the rotating ring 11 is no longer locked on the cylinder 3. Subsequently, the flat surface of the unlocking push block 26 contacts the round pin 18. As the inner rotating ring 25 continues to rotate, the unlocking push block 26 pushes the round pin 18, the base plate 15, the slide rod 14, and the slide block 13 to rotate synchronously, meaning that the rotating ring 11 rotates synchronously on the cylinder 3.

[0044] An insert block 27 is fixedly provided on the cylinder 3 and located on the side of the rotating ring 11. The insert block 27 has an insertion hole 2701. The inner rotating ring 25 has a double-headed round insert rod 28 for inserting into the insertion hole 2701.

[0045] Specifically, when the inner rotating ring 25 rotates, before the unlocking push block 26 contacts the round pin 18, the inner rotating ring 25 rotates synchronously with the double-headed round insert 28, so that one end of the double-headed round insert 28 is inserted into the socket 2701. This restricts the swaying of the cylinder 3 and the cable core 1 in the protective shell 2, which facilitates the transportation of the cable and prevents the shock absorption unit from being damaged by strong shaking during transportation. At the same time, before the unlocking push block 26 contacts the round pin 18, the swaying of the cylinder 3 and the cable core 1 is restricted, which makes it easier for the unlocking push block 26 to smoothly adjust the rotation position of the rotating ring 11 on the cylinder 3.

[0046] Considering that after one end of the double-ended round plug 28 is inserted into the socket 2701, the cylinder 3 and the cable core 1 no longer shake, but can still rotate along the socket 2701, a through hole 2702 communicating with the socket 2701 is provided on the side of the plug block 27. A pin 29 is slidably provided in the through hole 2702. A sub-plate 30 is provided on the bottom surface of the pin 29. A spring 31 is connected between the sub-plate 30 and the plug block 27. The end of the pin 29 located in the plug block 27 has an arc surface structure. Both ends of the double-ended round plug 28 are provided with inclined surfaces. A limiting plate 32 is provided on the inner retaining ring 20. A limiting hole 3201 for the pin 29 to be inserted is provided in the limiting plate 32.

[0047] Specifically, when one end of the double-ended round plug 28 is inserted into the socket 2701, the inclined surface of the double-ended round plug 28 contacts the arc surface of the pin 29. The inclined surface of the double-ended round plug 28 drives the pin 29 to move along the through hole 2702 toward the limiting hole 3201. The spring 2 31 is stretched, so that the pin 29 is inserted into the limiting hole 3201. The limiting hole 3201 is provided with a chamfer to facilitate the insertion of the pin 29. Therefore, the cylinder 3 and the cable core 1 will not rotate along the socket 2701, that is, the cylinder 3 and the cable core 1 are completely locked.

[0048] The outer rotating ring 23 is provided with a pointer 2301. The outer fixed ring 22 is fixed with a dial plate 33. The dial plate 33 is provided with a center groove 3301. The dial plate 33 is provided with locking grooves 3302 on both sides of the center groove 3301. The dial plate 33 is provided with dial plates 3303 on both sides of the locking grooves 3302.

[0049] Specifically, when pointer 2301 points to the center groove 3301, the double-headed round insert 28 on the inner rotating ring 25 is in the symmetrical position of the middle of the insert block 27, that is, neither end of the double-headed round insert 28 is in contact with the insert block 27, and the shock absorption unit is in working condition. Twisting the outer rotating ring 23 makes pointer 2301 align with a locking groove 3302. At this time, one end of the double-headed round insert 28 is inserted into the insert block 27, and the two unlocking push blocks 26 are not in contact with the round pin 18, thus locking the cylinder 3 and the cable core 1. Continuing to twist the outer rotating ring 23 makes pointer 2301 align with a dial 3303. At this time, the cylinder 3 and the cable core 1 are locked, and one unlocking push block 26 begins to contact the round pin 18, thereby causing the rotating ring 11 to rotate on the cylinder 3, adjusting the locking groove 1901 into which the locking block 17 is inserted.

[0050] Working principle: The protective shell 2 is fixedly installed on the cable bracket. The outer rotating ring 23 is rotated so that the pointer 2301 points to the center groove 3301. The double-headed round insert 28 on the inner rotating ring 25 is in the middle symmetrical position of the insert block 27, that is, neither end of the double-headed round insert 28 is in contact with the insert block 27. The shock absorption unit is in working state, that is, frictional damping is generated between the slider 5 and the slide groove 4, which together with the shock absorption spring 7 forms a shock absorption system. At this time, the spring 16 provides elastic force, so that the locking block 17 on the base plate 15 is inserted into the locking groove 1901. Therefore, the circular rotating ring 11 is locked on the cylinder 3. That is, the arc-shaped triangular block 12 on the circular rotating ring 11 pushes against the push rod 10, so that the push rod 10 and the top block 6 do not move. When the cable support vibrates along the cross-sectional direction of the protective shell 2, the cable support vibrates synchronously with the protective shell 2, and the cable core 1 sways within the cross-section of the protective shell 2. When the cable core 1 is close to the protective shell 2, the slider 5 moves along the groove 4 away from the block 9; when the cable core 1 is away from the protective shell 2, the slider 5 moves along the groove 4 towards the block 9. Therefore, the amplitude of the cable core 1 is less than the amplitude of the protective shell 2, giving the cable core 1 a shock-absorbing effect. Since the two ends of the connecting rod 8 are hinged to the slider 5 and the block 9 respectively using ball joints, the damping unit provides shock absorption regardless of the direction in which the cable support vibrates in the protective shell 2. When the cable support vibrates along the axial direction of the protective shell 2, the protective shell 2 vibrates synchronously along its axial direction, and all the sliders 5 slide synchronously in their corresponding grooves 4, making the amplitude of the cable core 1 also less than the amplitude of the protective shell 2, thus giving the cable core 1 a shock-absorbing effect.

[0051] Twisting the outer rotating ring 23 causes the pointer 2301 to align with a locking groove 3302. Power is transmitted through the rotating block 24, causing the inner rotating ring 25 to rotate synchronously. At this time, one end of the double-headed round insert 28 is inserted into the insert block 27. At this time, the two unlocking push blocks 26 are not in contact with the round pin 18. The inclined surface on the double-headed round insert 28 contacts the arc surface of the pin 29. The inclined surface of the double-headed round insert 28 drives the pin 29 to move along the through hole 2702 toward the limiting hole 3201. The spring 2 31 is stretched, causing the pin 29 to be inserted into the limiting hole 3201. The limiting hole 3201 has a chamfer to facilitate the insertion of the pin 29. Therefore, the cylinder 3 and the cable core 1 will not rotate along the insert hole 2701, that is, the cylinder 3 and the cable core 1 are completely locked, restricting the cylinder 3 and the cable core 1 from shaking in the protective shell 2. This facilitates the transportation of the cable and avoids damage to the shock absorption unit caused by strong shaking during the transportation of the cable. At the same time, before the unlocking push block 26 contacts the circular pin 18, the shaking of the cylinder 3 and the cable core 1 is restricted, so that the unlocking push block 26 can smoothly adjust the rotation position of the circular ring 11 on the cylinder 3.

[0052] Continuously rotate the outer rotating ring 23 until the pointer 2301 aligns with a dial 3303. At this point, the cylinder 3 and the cable core 1 are locked. An unlocking push block 26 begins to contact the round pin 18. The inclined surface of the unlocking push block 26 first contacts the round pin 18, driving the round pin 18 to move away from the locking plate 19. That is, the round pin 18, along with the base plate 15, slide rod 14, and locking block 17, moves along the slide block 13 away from the locking plate 19. The spring 16 is compressed, and the locking block 17 disengages from the locking groove 1901, meaning the rotating ring 11 is no longer locked to the cylinder 3. Subsequently, the flat surface of the unlocking push block 26 contacts the round pin 18. As the inner rotating ring 25 continues to rotate, the unlocking push block 26 pushes the round pin 18, base plate 15, slide rod 14, and slide block 13 to rotate synchronously, meaning the rotating ring 11 rotates synchronously on the cylinder 3. The rotating ring 11 drives the push rod 10 to move along the arc-shaped triangular block 12. The push rod 10 then moves the top block 6 along the slide groove 4. Adjusting the distance between the top block 6 and the slider 5 adjusts the tension of the damping spring 7, thus regulating the damping effect of the damping unit. When the damping spring 7 has been used for a long time, its elasticity weakens. Rotating the rotating ring 11 can strengthen the elasticity of the damping spring 7.

[0053] The outer rotating ring 23 is rotated in both directions to align the pointer 2301 with two different dials 3303, causing the two different unlocking push blocks 26 to contact the round pin 18 and push the round pin 18 and cylinder 3 to rotate in different directions. This, in turn, adjusts the distance between the top block 6 and the slider via the arc-shaped triangular block 12, thus controlling the extension and shortening of the damping spring 7. Simultaneously, controlling the scale on the dial 3303 aligned with the pointer 2301 controls the insertion of the locking block 17 into the locking groove 1901. After adjusting the locking groove 1901 into which the locking block 17 is inserted, the pointer 2301 is realigned with the center groove 3301, putting the damping unit into working condition. The friction between the outer rotating ring 23 and the outer fixed ring 22 keeps the outer rotating ring 23 in the upper position of the outer fixed ring 22. During adjustment, each group of damping units is adjusted sequentially to ensure that each group of damping units is in the same state.

[0054] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
