Description

Technical Field

[0001] The utility model relates to the technical field of cable sheaths, in particular to a cable structure with an impact-resistant sheath. Background Art

[0002] A cable structure with an impact-resistant sheath usually consists of a conductor, an insulating layer and a sheath. The sheath can protect the cable from external impact and damage. It can be made of special materials, such as rubber, polyvinyl chloride and other materials with good impact resistance. The thickness and hardness of the sheath can be designed according to the specific use environment and requirements to ensure that the cable can effectively protect the internal conductor and the insulating layer from damage when it is impacted; this cable structure is suitable for occasions that need to be frequently impacted or externally squeezed, such as industrial equipment, construction sites, etc. By adopting a cable structure with an impact-resistant sheath, the service life of the cable can be effectively extended and the reliability and safety of the equipment can be improved.

[0003] Generally, impact-resistant cable sheaths adopt a single-layer protective sleeve structure. In actual use, the protective sheath with this structure has limited impact resistance due to its thin wall, and is prone to dents. In addition, the sheath and the cable are often directly fitted and fixed, making it difficult to ensure that there is no gap between the sheath and the cable. The sheath may slip. Therefore, the above problems need to be improved. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a cable structure with an impact-resistant sheath.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cable structure with an impact-resistant sheath, comprising two upper and lower corrugated plates, a deformable sleeve is sleeved inside the two corrugated plates, a plurality of buffer grooves are equidistantly provided on the inner wall of the deformable sleeve along the length direction, a plurality of connecting holes are equidistantly provided on the inner wall of the deformable sleeve, a cavity is also provided in the inner wall of the deformable sleeve outside the connecting hole, a blocking block is installed in the cavity, a spring is provided in the cavity at the inner end of the blocking block, and the outer end of the blocking block extends from the inside of the connecting hole.

[0006] Preferably, the two corrugated plates are both semicircular, and flange plates are fixedly connected to the outer wall sides of the two corrugated plates.

[0007] Preferably, the flange plates are provided with a plurality of mounting holes equidistantly arranged along the length direction, and fixing bolts are provided between the mounting holes of the upper and lower flange plates.

[0008] Preferably, the deformable sleeve is in a circular tube shape, and the notch cross-section of the buffer groove is in a rectangular notch shape.

[0009] Preferably, the blocking block is cylindrical, an anti-dropping block is provided at the inner end of the blocking block, and the anti-dropping block is fixedly connected to a spring.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: in the present invention, a deformable sleeve is sleeved on the outer surface of the cable at the position requiring impact protection, and then the deformable sleeve is fixed with a corrugated plate. The longitudinal folds on the corrugated plate cause the sheath to deform when impacted to perform a preliminary impact resistance effect, and the buffer groove in the deformable sleeve can fit when the deformable sleeve is impacted, and does not directly transmit the impact force to the cable in the middle of the sheath, thereby alleviating the impact force and further protecting the cable. At the same time, the blocking block in the deformable sleeve can also alleviate the impact force under the action of a spring. The blocking block separates the deformable sleeve from the cable under the action of the spring to avoid direct contact with the reserved buffer distance, and the blocking block also plays a clamping role, fixing the sheath device at the protection position of the cable, which can effectively prevent the sheath from sliding from the protection position and failing to achieve a protective effect.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example: See Figure 1-4The utility model provides a cable structure with an impact-resistant sheath, comprising an upper and lower corrugated plate 1, wherein a deformable sleeve 4 is sleeved in the two corrugated plates 1, and a plurality of buffer grooves 5 are equidistantly provided on the inner wall of the deformable sleeve 4 in the extension direction, and a plurality of connecting holes 7 are equidistantly provided on the inner wall of the deformable sleeve 4, and a cavity 6 is also provided in the inner wall of the deformable sleeve 4 outside the connecting hole 7, and a blocking block 8 is installed in the cavity 6, and a spring 9 is provided in the cavity 6 at the inner end of the blocking block 8, and the outer end of the blocking block 8 extends from the inside of the connecting hole 7; the deformable sleeve 4 is fixed by the corrugated plate 1 to play a preliminary impact-resistant role, and the impact force received by the deformable sleeve 4 is buffered by the buffer groove 5, and at the same time, the blocking block 8 in the deformable sleeve 4 can also play a role in alleviating the impact force under the action of the spring 9, and can also increase the friction between the deformable sleeve 4 and the cable, so as to avoid the situation where the sheath slides from the protection position and fails to play a protective effect.

[0019] In the utility model, the two corrugated plates 1 are both semicircular, and the outer wall sides of the two corrugated plates 1 are fixedly connected with flange plates 2. A plurality of mounting holes are equidistantly provided on the flange plates 2 along the length direction, and fixing bolts 3 are provided between the mounting holes of the upper and lower flange plates 2; the two corrugated plates 1 are fixed by the fixing bolts 3 inserted in the mounting holes of the flange plates 2 to prevent the corrugated plates 1 from sliding.

[0020] In the utility model, the deformable sleeve 4 is in the shape of a circular tube, and the notch cross-section of the buffer groove 5 is in the shape of a rectangular notch; when the impact force when the outside of the sleeve is impacted is initially buffered by the corrugated plate 1, the remaining impact force is transmitted to the deformable sleeve 4, and the deformable sleeve 4 is squeezed under the action of the impact force. The radius becomes smaller, and at this time, the buffer groove 5 is also squeezed and fits, playing a buffering role, further dissolving the impact force and improving the protective effect of the sleeve.

[0021] In the utility model, the blocking block 8 is cylindrical, and an anti-slip block is provided at the inner end of the blocking block 8, and the anti-slip block is fixedly connected to the spring 9; when the cable is impacted and vibrates, the blocking block 8 in the deformable sleeve 4 buffers the cable under the action of the spring 9, avoiding direct contact between the cable and the deformable sleeve 4 to prevent the impact force from being directly transmitted to the cable. At the same time, the blocking block 8 also plays a role of clamping and reinforcement, preventing the sheath from sliding from the protective position of the cable.

[0022] Working principle: when the utility model is used, the deformable sleeve 4 is first sleeved on the predetermined position of the cable, and then the upper and lower ends of the outer surface of the deformable sleeve 4 are secondary coated with the corrugated plate 1, and the corrugated plate 1 is fixed with the fixing bolts 3. When the cable is impacted at this position, the corrugated plate 1 of the outermost layer of the sheath first relieves the impact force, and the longitudinal folds in the middle of the corrugated plate 1 are deformed under the action of the impact force to relieve the impact. At the same time, the second layer of anti-impact mechanism deformable sleeve 4 added in the middle of the corrugated plate 1 bears the remaining impact force. When the deformable sleeve 4 is impacted, the buffer groove 5 on the inner wall fits under the action of the impact force to play a buffering role. At the same time, when the cable is impacted and vibrates, the blocking block 8 protruding on the inner wall of the deformable sleeve 4 is pressed into the cavity 6. After the impact, the spring 9 is reset, and the blocking block 8 rebounds the cable under the action of the spring 9, and the impact force on the cable is converted into elastic force, so as to avoid damage to the cable caused by external collision and impact.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
