Description

[0001] The present invention relates to the technical field of cables, and more particularly to a cable with a shockproof function. Background Art

[0002] Cables are often subject to vibration in applications, especially in complex environments or dynamic conditions. This vibration can not only cause wire breakage or poor contact within the cable, but also impair signal transmission. Traditional cable designs often lack effective vibration-proofing mechanisms and are unable to effectively address the challenges posed by vibration.

DETAILED DESCRIPTION

[0031] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0032] Example: See Figure 1-12 Structural schematic diagram, the present invention provides the following technical solutions: a cable with shockproof function, comprising a cable core 1, a protective shell 2 on the outside of the cable core 1, a plurality of shock-absorbing units arranged between the cable core 1 and the protective shell 2, each group of shock-absorbing units comprising two cylinders 3 fixedly arranged on the outside of the cable core 1, four slide grooves 4 evenly provided on the opposite sides of the two cylinders 3, sliders 5 and top blocks 6 slidingly provided on the slide grooves 4 in sequence, and a shock-absorbing spring 7 is connected between the slider 5 and the top block 6, the four slide grooves 4 on the two cylinders 3 correspond one to one, a block 9 is provided between the two corresponding slide grooves 4, and the block 9 is provided on the inner 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 hinged to the corresponding slider 5 and the ball head of the block 9 respectively, and 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 support, and friction damping is generated between the slider 5 and the slide groove 4, which together with the shock-absorbing spring 7 form a shock-absorbing system. When the cable support vibrates in 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 in the cross-sectional direction of the protective shell 2. When the cable core 1 approaches one side of the protective shell 2, the slider 5 moves along the slide groove 4 away from the block 9; when the cable core 1 moves away from one side of the protective shell 2, the slider 5 moves along the slide groove 4 toward the block 9, so that the amplitude of the cable core 1 is smaller than the amplitude of the protective shell 2, making the cable core 1 shock-proof. Since the two ends of the connecting rod 8 are respectively hinged to the slider 5 and the block 9 in a ball head manner, the shock-absorbing unit has a shock-proof effect when the cable support vibrates in any direction of the protective shell 2. When the cable holder 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 slide grooves 4, so that the amplitude of the cable core 1 is also smaller than the amplitude of the protective shell 2, so that the cable core 1 has a shock-proof effect.

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

[0035] Specifically, rotating ring 11 on cylinder 3 causes arcuate triangular block 12 to move push rod 10, which in turn moves push rod 10 with push block 6 along chute 4. Adjusting the distance between push block 6 and slider 5 adjusts the tightness of shock-absorbing spring 7, thereby adjusting the shock-absorbing effect of the shock-absorbing unit. If shock-absorbing spring 7 loses its elasticity over time, rotating ring 11 can also strengthen its elasticity.

[0036] A slide seat 13 is provided on the side of the rotating ring 11, and a slide rod 14 is provided on the slide seat 13 for sliding along the radial direction of the cable core 1. A bottom plate 15 is provided at the bottom of the slide rod 14, and a spring 16 is provided on the outer sleeve of the slide rod 14. The two ends of the spring 16 are respectively connected to the bottom plate 15 and the slide seat 13. A locking block 17 is provided at the bottom of the bottom plate 15, and a round pin 18 is provided on the side of the bottom plate 15; a locking plate 19 is fixed on the cylinder 3, and a plurality of locking grooves 1901 are provided in the locking plate 19 for inserting the locking blocks 17.

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

[0038] An inner fixing ring 20 is fixedly provided on the inner wall of the protective shell 2 and at the cylinder 3. A connecting block 21 is provided on the outer side of the inner fixing ring 20. A ring hole 1 201 is provided on the protective shell 2 for the connecting block 21 to pass through. An outer fixing ring 22 is provided on the outer side of the connecting block 21. The inner fixing ring 20 and the outer fixing ring 22 clamp the protective shell 2. An inner rotating groove 2001 is provided on the inner fixing ring 20, an outer rotating groove 2201 is provided on the outer fixing ring 22, and a ring hole 202 is provided on the protective shell 2. The inner rotating groove 2001, the outer rotating groove 2201 and the ring hole 202 coincide with each other.

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

[0040] Specifically, by rotating the outer rotating ring 23 and transmitting power through the rotating connecting block 24, the inner rotating ring 25 can be driven to rotate on the inner wall of the inner fixed ring 20. The outer rotating ring 23 and the outer fixed ring 22 as well as the inner rotating ring 25 and the inner fixed ring 20 are tightly sealed.

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

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

[0043] Specifically, the inner swivel 25 rotates with the round pin 18, and the inclined surface of the unlocking push block 26 first contacts the round pin 18, which drives the round pin 18 to move away from the locking plate 19. That is, the round pin 18 moves along the bottom plate 15, the slide bar 14, and the locking block 17 along the slide 13 away from the locking plate 19. The spring 16 is compressed, and the locking block 17 disengages from the locking groove 1901, that is, the swivel 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 swivel 25 continues to rotate, the unlocking push block 26 pushes the round pin 18, the bottom plate 15, the slide bar 14, and the slide 13 to rotate synchronously, that is, the swivel ring 11 rotates synchronously on the cylinder 3.

[0044] An insert block 27 is fixedly provided on the cylinder 3 and located beside the circular rotating ring 11 . A plug hole 2701 is provided in the insert block 27 . A double-headed round insert rod 28 for inserting into the plug hole 2701 is provided on the inner rotating ring 25 .

[0045] Specifically, when the inner swivel 25 rotates, before the unlocking push block 26 contacts the round pin 18, the inner swivel 25 rotates synchronously with the double-ended round plug rod 28, so that one end of the double-ended round plug rod 28 is inserted into the insertion hole 2701. This can prevent the cylinder 3 and the cable core 1 from shaking in the protective shell 2, thereby facilitating the transportation of the cable and preventing damage to the shock absorber unit due to strong shaking during transportation. At the same time, before the unlocking push block 26 contacts the round pin 18, the shaking of the cylinder 3 and the cable core 1 is restricted, facilitating the unlocking push block 26 to smoothly adjust the rotational position of the swivel 11 on the cylinder 3.

[0046] Considering that after one end of the double-ended round plug rod 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 is provided on the side of the plug block 27, which penetrates the socket 2701. A latch 29 is slidably provided in the through hole 2702. A sub-plate 30 is provided on the bottom surface of the latch 29. A spring 21 is connected between the sub-plate 30 and the plug block 27. The end of the latch 29 located in the plug block 27 is a curved structure. Both ends of the double-ended round plug rod 28 are provided with inclined surfaces. A limit plate 32 is provided on the inner fixing ring 20, and a limit hole 3201 is provided in the limit plate 32 for the insertion of the latch 29.

[0047] Specifically, when one end of the double-headed round insertion rod 28 is inserted into the socket 2701, the inclined surface on the double-headed round insertion rod 28 contacts the arc surface of the pin 29, and the inclined surface of the double-headed round insertion rod 28 drives the pin 29 to move along the through hole 2702 toward the limiting hole 3201. The spring 2 31 is stretched to insert the pin 29 into the limiting hole 3201. The limiting hole 3201 is provided with a chamfer to facilitate the insertion of the pin 29, so 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] A pointer 2301 is provided on the outer rotating ring 23, and a disc plate 33 is fixedly provided on the outer side of the outer fixed ring 22. The disc plate 33 has a center groove 3301, locking grooves 3302 are provided on both sides of the center groove 3301, and discs 3303 are provided on the sides of the locking groove 3302.

[0049] Specifically, when pointer 2301 points to the center notch 3301, the double-ended circular rod 28 on the inner swivel ring 25 is symmetrically positioned in the middle of the insert block 27, meaning that neither end of the double-ended circular rod 28 contacts the insert block 27, and the shock absorber is in operation. The outer swivel ring 23 is twisted to align pointer 2301 with one of the locking notches 3302. At this point, one end of the double-ended circular rod 28 is inserted into the insert block 27, and the two unlocking push blocks 26 no longer contact the round pin 18, thereby locking the cylinder 3 and the cable core 1. The outer swivel ring 23 is continuously twisted to align pointer 2301 with one of the discs 3303. At this point, the cylinder 3 and the cable core 1 are locked, and one of the unlocking push blocks 26 contacts the round pin 18, causing the swivel ring 11 to rotate on the cylinder 3, adjusting the locking notch 1901 into which the locking block 17 is inserted.

[0050] Working Principle: Securely mount protective housing 2 on the cable bracket, rotate outer swivel ring 23 until pointer 2301 points to center notch 3301. Double-ended circular rod 28 on inner swivel ring 25 is symmetrically positioned between insert block 27, meaning neither end of rod 28 contacts insert block 27. The damping unit is in operation, generating frictional damping between slider 5 and chute 4, which together with damping spring 7 forms a damping system. At this point, spring 16 provides the elastic force that forces locking block 17 on base plate 15 into locking slot 1901, locking swivel ring 11 onto cylinder 3. This forces arc-shaped triangular block 12 on swivel ring 11 against push rod 10, preventing push rod 10 and push block 6 from moving. When the cable holder vibrates in the cross-sectional direction of the protective shell 2, the cable holder vibrates synchronously with the protective shell 2, and the cable core 1 sways in the cross-sectional direction of the protective shell 2. When the cable core 1 approaches one side of the protective shell 2, the slider 5 moves along the slide 4 in the direction away from the block 9; when the cable core 1 moves away from one side of the protective shell 2, the slider 5 moves along the slide 4 in the direction toward the block 9, so that the amplitude of the cable core 1 is smaller than the amplitude of the protective shell 2, making the cable core 1 shockproof. Because the two ends of the connecting rod 8 are respectively hinged to the slider 5 and the block 9 in a ball head manner, the cable holder vibrates in any direction of the protective shell 2, and the shock-absorbing unit has a shockproof effect. When the cable holder 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 slide 4, so that the amplitude of the cable core 1 is also smaller than the amplitude of the protective shell 2, making the cable core 1 shockproof.

[0051] The outer rotating ring 23 is twisted so that the pointer 2301 is aligned with a locking groove 3302, and the power is transmitted through the rotating connecting block 24 to make the inner rotating ring 25 rotate synchronously. At this time, one end of the double-headed round plug rod 28 is inserted into the plug block 27. At this time, the two unlocking push blocks 26 do not contact the round pin 18, and the inclined surface on the double-headed round plug rod 28 contacts the arc surface of the latch 29. The inclined surface of the double-headed round plug rod 28 drives the latch 29 to move along the through hole 2702 toward the limit hole 3201. The spring 2 31 is stretched to make the latch 29 inserted into the limit hole 3201. The limit hole 3201 is provided with a chamfer that facilitates the insertion of the latch 29, so the cylinder 3 and the cable core 1 will not rotate along the insertion hole 2701, that is, the cylinder 3 and the cable core 1 are completely locked, limiting the cylinder 3 and the cable core 1 from shaking in the protective shell 2, which is convenient for transportation of the cable and avoids damage to the shock absorbing unit due to strong shaking of the cable during transportation. At the same time, before the unlocking push block 26 contacts the round 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] The outer rotating ring 23 is continuously twisted until the pointer 2301 is aligned with a scale plate 3303. At this point, the cylinder 3 and the cable core 1 are locked, and 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, 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 moves along the slide 13 away from the locking plate 19 with the base plate 15, the slide bar 14, and the locking block 17. The spring 16 is compressed, and the locking block 17 disengages from the locking groove 1901, that is, 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 bar 14, and the slide 13 to rotate synchronously, that is, the rotating ring 11 rotates synchronously on the cylinder 3. Rotating ring 11, with its curved triangular block 12, drives push rod 10, which in turn drives push rod 10 with push block 6 along chute 4. Adjusting the distance between push block 6 and slider 5 adjusts the tightness of damping spring 7, thereby adjusting the damping effect of the damping unit. If damping spring 7 loses its elasticity over time, rotating ring 11 can also strengthen its elasticity.

[0053] By twisting the outer rotating ring 23 forward and backward, the pointer 2301 aligns with two different discs 3303. This allows two different unlocking pushers 26 to contact the round pin 18, pushing the round pin 18 and the cylinder 3 in different directions. This, in turn, adjusts the distance between the top block 6 and the slider via the curved triangular block 12, thereby controlling the extension and contraction of the shock absorber spring 7. Simultaneously, controlling the scale on the disc 3303 that the pointer 2301 aligns with controls the locking slot 1901 into which the locking block 17 is inserted. After adjusting the locking slot 1901, the pointer 2301 is realigned with the center groove 3301, placing the shock absorber unit in operation. The friction between the outer rotating ring 23 and the outer fixed ring 22 ensures that the outer rotating ring 23 maintains its upper position on the outer fixed ring 22. During adjustment, each set of shock absorbers is adjusted sequentially to ensure that each set is in the same state.

[0054] The above are only 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 based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all within the scope of protection of the present invention.
