[0003] Similar to the above-mentioned cable protection sleeve: Although the long strip protection sleeve body formed by multiple tubes spliced ​​together can effectively protect the cable from damage, first of all, the existing connection protection sleeve is generally connected by hot melt or welding flanges, and tools are required to complete the installation during assembly. Secondly, during the installation process, the protection sleeve is collided or impacted, causing damage to the internal cable, and it does not have a buffering effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and the MPP power cable protective sleeve is proposed to achieve a more practical purpose. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: an MPP power cable protection sleeve, comprising a lower sleeve 1, an upper sleeve 2 and a clamping block 4. The top side of the lower sleeve 1 is connected to the upper sleeve 2 through a rotating shaft 3. The upper sleeve 2 corresponds to the lower sleeve 1. The upper sleeve 2 and the lower sleeve 1 are combined into a sleeve shape to protect the power cable. The clamping block 4 is arranged at the bottom of the end of the upper sleeve 2 away from the rotating shaft 3. The bottom end of the clamping block 4 is connected with a clamping portion 41. The clamping block 4 and the clamping portion 41 play a clamping role. The end of the lower sleeve 1 away from the rotating shaft 3 is connected with a fixing block 5. The fixing block 5 plays a fixing role. A clamping groove 6 is provided in the middle of the fixing block 5, and the clamping block 4 is embedded in the clamping groove 6.

[0021] A limiting groove 7 is provided on one side of the card slot 6, and a top block 8 is embedded in the limiting groove 7. The end of the top block 8 close to the inner wall of the limiting groove 7 is connected to a pull rod 9, and the pull rod 9 plays a connecting role. The outer wall of the pull rod 9 is provided with a spring 10. The spring 10 shrinks under pressure, and the end of the pull rod 9 away from the top block 8 passes through the fixed block 5 and is connected to the pull block 11. When the power cable needs to be protected and installed, the cable can be placed in the middle of the lower sleeve 1 and the upper sleeve 2, and the upper sleeve 2 is covered with the lower sleeve 1. The card block 4 at the edge of the upper sleeve 2 is embedded in the card The rear clamping portion 41 in the slot 6 pushes the top block 8, and the top block 8 drives the pull rod 9 to translate into the limiting slot 7, and the spring 10 is compressed and contracts. When the clamping portion 41 at the bottom of the block 4 moves to the bottom end of the slot 6, the spring 10 pushes the top block 8 toward the block 4 due to its resilience, thereby engaging the clamping portion 41 at the bottom end of the block 4, thereby protecting the power cable. When disassembling, pull the pull block to drive the pull rod and the top block 8 to translate into the limiting slot, so that the top block 8 cancels the engagement with the clamping portion 41 and then lifts the upper sleeve 2 to complete the disassembly.

[0022] The inner walls of the upper sleeve 2 and the lower sleeve 1 are connected with a buffer mechanism 12. The buffer mechanism 12 plays a buffering role to prevent the cable from being damaged by collision or impact of the protective sleeve during installation. The buffer mechanism 12 includes a fixed sleeve 13, a rebound column 14, a limiting top plate 15, a support spring 16 and a damping ring 17. Multiple groups of fixed sleeves 13 are respectively connected to the inner walls of the upper sleeve 2 and the lower sleeve 1. A rebound column 14 is embedded in one end of the fixed sleeve 13, and the rebound column 14 can slide in the fixed sleeve 13.

[0023] The end of the rebound column 14 away from the fixed sleeve 13 is connected to the limiting top plate 15, and the outer wall of the rebound column 14 away from the fixed sleeve 13 is provided with a supporting spring 16. The outer wall of the rebound column 14 embedded in the side of the fixed sleeve 13 is provided with a damping ring 17, and the outer wall of the damping ring 17 abuts against the inner wall of the fixed sleeve 13. When the protective sleeve is impacted, collided or knocked, the rebound column 14 slides downward into the fixed sleeve 13, and the support spring 16 on the outer wall of the rebound column 14 plays a shock-absorbing role. After buffering, the support spring 16 drives the rebound column 13 to rebound upward, and a certain resistance is generated by the friction between the damping ring 17 on the bottom surface of the rebound column 14 and the inner wall of the fixed sleeve 13 to suppress the vibration of the support spring 16 when it rebounds after shock absorption, thereby playing a shock-absorbing and buffering effect, thereby better protecting the power cable from damage caused by the impact of collision.

[0024] The opposite sides of the upper and lower buffer mechanisms 12 are connected to inner sleeves 18, which serve as a limiter. The two groups of inner sleeves 18 are semicircular and correspond to each other. The two groups of inner sleeves 18 are closed into a cylindrical shape to protect the cables. The inner walls of the two groups of inner sleeves 18 are arranged and connected with No. 2 springs 19, which shrink under pressure.

[0025] The end of the No. 2 spring 19 away from the inner sleeve 18 is connected to a clamping plate 20, which is arc-shaped and plays the role of clamping the cable. The No. 2 spring 19 pushes the clamping plate 20 to fix the cable, thereby fixing the cable and avoiding gaps between the internal cable and the protective sleeve after assembly. Reinforcing ribs 21 are provided inside the lower sleeve 1 and the upper sleeve 2. The reinforcing ribs 21 play a reinforcing role and increase the strength of the protective sleeve.

[0026] Working principle: When using the MPP power cable protection sleeve, the cable can be placed in the middle of the lower sleeve 1 and the upper sleeve 2, and the upper sleeve 2 and the lower sleeve 1 are covered. The clamping block 4 at the edge of the upper sleeve 2 is embedded in the clamping groove 6, and the clamping portion 41 pushes the top block 8, and the top block 8 drives the pull rod 9 to move horizontally into the limiting groove 7. The spring 10 is compressed and contracts. When the clamping portion 41 at the bottom of the clamping block 4 moves to the bottom end of the clamping groove 6, the spring 10 pushes the top block 8 to move toward the clamping block 4 due to the resilience of the spring 10, thereby locking the clamping portion 41 at the bottom end of the clamping block 4, thereby protecting the power cable. When disassembling, pull the pull block to drive the pull rod and the top block 8 to move horizontally into the limiting groove, so that the top block 8 cancels the clamping between the clamping portion 41 and then lifts the upper sleeve 2 to complete the disassembly. When the protective sleeve is impacted or knocked, When the collision occurs, the rebound column 14 slides downward into the fixed sleeve 13, and the support spring 16 on the outer wall of the rebound column 14 plays a shock-absorbing role. After buffering, the support spring 16 drives the rebound column 13 to rebound upward, and the damping ring 17 on the bottom surface of the rebound column 14 rubs with the inner wall of the fixed sleeve 13 to generate a certain resistance to suppress the vibration of the support spring 16 when it rebounds after shock absorption, thereby playing a shock-absorbing and buffering effect, thereby better protecting the power cable from damage to the cable caused by the impact of the collision. The No. 2 spring 19 pushes the clamping plate 20 to fix the cable to be connected, thereby playing a fixed positioning role for the cable to avoid gaps between the internal cable and the protective sleeve after assembly. Reinforcing ribs 21 are provided inside the lower sleeve 1 and the upper sleeve 2, and the reinforcing ribs 21 play a reinforcing role to increase the strength of the protective sleeve.
