Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a cable protective cover. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly used for controlling installation, connecting devices, transmitting electricity, and other multiple functions. They are common and indispensable in daily life.

[0003] A Chinese patent with publication number CN207283088U discloses a cable protective sleeve, comprising a sleeve body, wherein the sleeve body is provided with a protective layer 1, a buffer zone, and a protective layer 2 in sequence from the inside to the outside, and at least three elastic support bodies uniformly distributed in the circumferential direction are provided in the buffer zone, wherein the elastic support body comprises an elastic support rod and a spring sleeved outside the elastic support rod, wherein the two ends of the elastic support rod are respectively connected to the protective layer 1 and the protective layer 2, and the buffer zone is divided into multiple chambers by at least three elastic support bodies, and an air cushion is provided in each chamber for improving the compressive performance of the cable.

[0004] The cables in the above structure can protect the cables inside the protective layer 2 through at least three elastic support bodies evenly distributed circumferentially in the buffer zone, thereby reducing the probability of the cables being damaged when squeezed. At the same time, the air cushion arranged in the buffer zone can also protect the cables in the protective layer 2, thereby further reducing the probability of the cables being damaged when squeezed. However, due to the large length of the cable, if you want to improve the compression resistance of the entire cable, you need to set a large number of elastic support bodies at axial intervals along the cable. It is difficult to install a large number of elastic support bodies in the buffer zone, and the workload of the staff is large. Utility Model Content

[0005] The utility model addresses the shortcomings of the prior art in that, due to the large length of the cable, a large number of elastic support bodies need to be arranged at intervals along the axial direction of the cable in order to improve the compression resistance of the entire cable. However, it is difficult to install a large number of elastic support bodies in the buffer zone and the workload of the staff is large. The utility model provides a cable protective cover that is easy to produce.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A cable protective cover comprises an inner protective cover for installing a cable inside and an outer protective cover arranged outside the inner protective cover, a pressure-resistant structure for reducing the probability of the cable installed in the inner protective cover being damaged by external force is arranged between the inner protective cover and the outer protective cover, the pressure-resistant structure comprises a plurality of first pressure-resistant plates circumferentially arranged on the outer wall of the inner protective cover and extending axially along the inner protective cover, and a plurality of second pressure-resistant plates circumferentially arranged on the inner wall of the outer protective cover and extending axially along the outer protective cover, the first pressure-resistant plates and the second pressure-resistant plates being cross-inserted.

[0008] By adopting the above scheme, the first anti-pressure plate arranged on the inner protective sleeve can support the outer protective sleeve when the outer protective sleeve is under pressure, thereby reducing the pressure on the outer protective sleeve. At the same time, the second anti-pressure plate arranged on the inner wall of the outer protective sleeve can squeeze the inner protective sleeve when the outer protective sleeve is under pressure. At this time, the inner protective sleeve will also exert a reaction force on the first anti-pressure plate, thereby reducing the pressure on the inner protective sleeve and reducing the probability of the cable in the inner protective sleeve being damaged by pressure. The first anti-pressure plate is arranged to extend along the axial direction of the inner protective sleeve, so that the first anti-pressure plate can be formed as one piece with the inner protective sleeve, and the second anti-pressure plate is arranged to extend along the axial direction of the outer protective sleeve, so that the second anti-pressure plate can be formed as one piece with the outer protective sleeve, thereby reducing the time required for the production of the protective sleeve and reducing the workload of the workers.

[0009] Preferably, the first and second anti-compression plates are larger at the top and bottom and smaller in the middle.

[0010] Preferably, the spacing between any two adjacent first pressure-resistant plates is equal to the width of the second pressure-resistant plates, and the spacing between any two adjacent second pressure-resistant plates is equal to the width between the first pressure-resistant plates.

[0011] When the outer protective cover is deformed under pressure, the outer protective cover will exert pressure on the first anti-pressure plate. At this time, the first anti-pressure plate will also exert a reaction force on the outer protective cover to support the outer protective cover, thereby reducing the pressure transmitted from the outer protective cover to the inner protective cover. When the first anti-pressure plate is under pressure, because the first anti-pressure plate is inserted between the two second anti-pressure plates and the first anti-pressure plate and the second anti-pressure plate are in a shape of larger upper and lower parts and smaller middle parts, when the first anti-pressure plate is squeezed, the second anti-pressure plate will also support the first anti-pressure plate, thereby further reducing the pressure transmitted from the outer protective cover to the inner The pressure on the protective cover, and the second pressure-resistant plate arranged on the outer protective cover will also apply pressure to the inner protective cover, so that the inner protective cover gives it a reaction force, thereby further reducing the pressure transmitted from the outer protective cover to the inner protective cover. At the same time, because the second pressure-resistant plate is inserted between the two first pressure-resistant plates, when the second pressure-resistant plate is under pressure, the first pressure-resistant plate will also support the second pressure-resistant plate, thereby further reducing the pressure transmitted from the outer protective cover to the inner protective cover, reducing the deformation amplitude of the inner protective cover, and reducing the probability of the cable installed in the inner protective cover being damaged by pressure.

[0012] Preferably, a supporting component is provided in the inner protective cover to further reduce the probability of damage to the cables in the inner protective cover due to compression.

[0013] Preferably, the support component includes a central axis arranged at the center of the inner protective sleeve and extending axially along the inner protective sleeve, and a plurality of support plates circumferentially arranged on the outer wall of the central axis and extending axially toward the central axis, and the end of the support plate away from the central axis is connected to the inner protective sleeve.

[0014] By adopting the above scheme, the inner protective sleeve can be supported by the support plates that are circumferentially arranged on the outer wall of the central shaft, thereby reducing the deformation amplitude of the inner protective sleeve when it is under pressure, reducing the pressure on the cables installed in the inner protective sleeve, and thus reducing the probability of the cables being damaged by pressure. At the same time, the support plates are extended axially along the central shaft, so that the support plates and the central shaft can be formed as one piece, which makes production more convenient and reduces the workload of workers.

[0015] Preferably, the distance between any two adjacent support plates is greater than the diameter of a single cable, and the single cable is inserted between the two support plates.

[0016] By adopting the above scheme, the spacing between two adjacent support plates is set to be larger than the diameter of a single cable, so that a single cable can be inserted between two adjacent support plates. When the cable equipped with the cable protective cover is under pressure, the support plate will support the inner protective cover to reduce the amplitude of its deformation, thereby reducing the compressive force on the cable inserted between two adjacent support plates and reducing the probability of cable damage due to pressure. At the same time, multiple cables are inserted into two support plates respectively, which can also reduce the probability of short circuit due to contact between the wire cores inside the two cables.

[0017] Due to the adoption of the above technical scheme, the present invention has significant technical effects: the first anti-pressure plate arranged on the inner protective sleeve can support the outer protective sleeve when the outer protective sleeve is under pressure, thereby reducing the pressure on the outer protective sleeve; at the same time, the second anti-pressure plate arranged on the inner wall of the outer protective sleeve can squeeze the inner protective sleeve when the outer protective sleeve is under pressure. At this time, the inner protective sleeve will also exert a reaction force on the first anti-pressure plate, thereby reducing the pressure on the inner protective sleeve and reducing the probability of the cable in the inner protective sleeve being damaged by pressure; the first anti-pressure plate is arranged to extend along the axial direction of the inner protective sleeve, so that the first anti-pressure plate can be integrally formed with the inner protective sleeve, and the second anti-pressure plate is arranged to extend along the axial direction of the outer protective sleeve, so that the second anti-pressure plate can be integrally formed with the outer protective sleeve, thereby reducing the time required for the production of the protective sleeve and reducing the workload of the workers.

[0023] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0024] Example

[0025] A cable protective cover, reference Figure 1 , including an inner protective sleeve 2 for installing a cable 1 inside and an outer protective sleeve 3 sleeved outside the inner protective sleeve 2, a pressure-resistant structure is provided between the inner protective sleeve 2 and the outer protective sleeve 3 to reduce the probability of the cable 1 installed in the inner protective sleeve 2 being damaged by external force, the pressure-resistant structure includes a plurality of first pressure-resistant plates 401 circumferentially arranged on the outer wall of the inner protective sleeve 2 and extending axially along the inner protective sleeve 2, and a plurality of second pressure-resistant plates 402 circumferentially arranged on the inner wall of the outer protective sleeve 3 and extending axially along the outer protective sleeve 3, the first pressure-resistant plates 401 and the second pressure-resistant plates 402 are cross-inserted, in this embodiment, the material of the first pressure-resistant plates 401 is the same as that of the inner protective sleeve 2, the material of the second pressure-resistant plates 402 is the same as that of the outer protective sleeve 3, and the materials of the inner protective sleeve 2 and the outer protective sleeve 3 are both PVC material or PE material, so that the first pressure-resistant plates 401 and the inner protective sleeve 2 are integrally formed, and the second pressure-resistant plates 402 and the outer protective sleeve 3 are integrally formed.

[0026] refer to Figure 1-Figure 4 The first pressure-resistant plate 401 and the second pressure-resistant plate 402 are in a shape that is larger at the top and bottom and smaller in the middle. The spacing between two adjacent first pressure-resistant plates 401 is equal to the width of the second pressure-resistant plates 402, and the spacing between two adjacent second pressure-resistant plates 402 is equal to the width between the first pressure-resistant plates 401.

[0027] A support component is also provided in the inner protective sleeve 2 to further reduce the probability of the cable 1 in the inner protective sleeve 2 being damaged by pressure. The support component includes a central axis 5 arranged at the center of the inner protective sleeve 2 and extending axially along the inner protective sleeve 2, and a plurality of support plates 6 circumferentially arranged on the outer wall of the central axis 5 and extending axially toward the central axis 5. The end of the support plate 6 away from the central axis 5 is connected to the inner protective sleeve 2. In this embodiment, the materials used for the support component and the inner protective sleeve 2 are the same, both of which are PVC or PE materials, so that the support component and the inner protective sleeve 2 are easily integrated into one piece. The spacing between two adjacent support plates 6 is greater than the diameter of a single cable 1 and a single cable 1 is inserted between two support plates 6.

[0028] Specific process: First, an inner protective cover 2 with a first pressure-resistant plate 401 and a supporting component and an outer protective cover 3 with a second pressure-resistant plate 402 are integrally formed. Then, the first pressure-resistant plate 401 on the inner protective cover 2 is aligned with the gap between two adjacent second pressure-resistant plates 402 on the inner wall of the outer protective cover 3. Then, the inner protective cover 2 is inserted into the outer protective cover 3. Finally, multiple cables 1 are respectively inserted into the gaps between two adjacent support plates 6. The production of the entire cable can be completed, the installation is simpler, and the workload of workers is reduced. When the outer protective cover 3 is under pressure, the first pressure-resistant plate 401 arranged outside the inner protective cover 2 will support the outer protective cover 3. At the same time, the first pressure-resistant plate 401 and the second pressure-resistant plate 402 will also squeeze each other, so that the second pressure-resistant plate 402 is pressed against the outer protective cover 3. The first pressure-resistant plate 401 provides support, and when the outer protective sleeve 3 is under pressure, the second pressure-resistant plate 402 will also squeeze the inner protective sleeve 2, so that the inner protective sleeve 2 supports the second pressure-resistant plate 402. At the same time, due to the mutual squeezing of the first pressure-resistant plate 401 and the second pressure-resistant plate 402, the first pressure-resistant plate 401 will also support the second pressure-resistant plate 402, thereby reducing the probability of the cable 1 installed in the inner protective sleeve 2 being damaged by pressure. At the same time, the support plate 6 arranged inside the inner protective sleeve 2 will also support the inner protective sleeve 2, thereby reducing the deformation amplitude of the inner protective sleeve 2, thereby further reducing the probability of the cable 1 between the two support plates 6 being damaged by pressure. Since multiple cables 1 are separated from each other by the support plate 6, the probability of short circuit caused by contact between the cores of the two cables 1 can also be reduced.
