[0020] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following is combined with the figure and example, and the utility model is further detailedly explained.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.

[0021] The specific implementation of the utility model is described in detail in the following combined with specific embodiments.

[0022] Please refer to Figures 1 to 3The utility model discloses a high stability electric power fitting, the high stability electric power fitting includes sleeve joint barrel 1, elastic fold damping air bag 2, elastic fold gas storage air bag 3.

[0023] In the embodiment of the utility model, refer to Figure 1 And Figure 2 Two annular grooves 1a that symmetrically distribute are seted up in sleeve joint barrel 1, and the elastic fold damping air bag 2 is installed in each annular groove 1a, the outer bag wall of elastic fold damping air bag 2 is fixedly connected with the inner ring wall of annular groove 1a, two elastic fold gas storage air bags 3 that symmetrically distribute are still sleeved on sleeve joint barrel 1, and two elastic fold gas storage air bags 3 are located at both ends of sleeve joint barrel 1, and elastic fold gas storage air bag 3 is communicated with corresponding elastic fold damping air bag 2 through gas guide pipe 31,

[0024] And the outer cylinder wall of sleeve joint barrel 1 sets up two sections of symmetric distribution's outer thread section 12, and the threaded connection for pressing and fitting elastic fold gas storage air bag 3 is set up on two sections of outer thread section 12 and is used for the screw thread of pressing and fitting elastic fold gas storage air bag 3, and the both ends of sleeve joint barrel 1 are fixedly installed with the abutting disc 11, and the outside bag wall of elastic fold gas storage air bag 3 is fixedly connected with the inner disc wall of abutting disc 11, and the inside bag wall of elastic fold gas storage air bag 3 is abutted with the outer ring wall of screw thread abutting ring 4,

[0025] Need to explain: after the cable is passed through sleeve joint barrel 1, rotates the screw thread abutting ring 4 of both sides, so that screw thread abutting ring 4 is rotated along outer thread section 12 to the direction of abutting disc 11, and the gas in elastic fold gas storage air bag 3 is rapidly flowed into elastic fold damping air bag 2 after being extruded by screw thread abutting ring 4, therefore, elastic fold damping air bag 2 is filled and expands rapidly, and the elastic fold damping air bag 2 after expansion fills the gap between cable and sleeve joint barrel 1, and then firmly presses the cable in sleeve joint barrel 1 and realizes the fixation of cable, since the elastic fold damping air bag 2 after expansion is the elastic structure, when the cable is affected by wind and appears to shake or swing, the elastic fold damping air bag 2 after expansion can effectively reduce the swing amplitude of cable, when sleeve joint barrel 1 needs to be disassembled, reversely rotates screw thread abutting ring 4 so that screw thread abutting ring 4 no longer abuts elastic fold damping air bag 2, at this time, the airflow in elastic fold damping air bag 2 is backflowed to elastic fold gas storage air bag 3, so that the cable passing through sleeve joint barrel 1 can be quickly extracted, therefore, the installation and disassembly of sleeve joint barrel 1 to cable can be quickly realized, and the problem that the cable appears to loosen is effectively avoided, and the stability of cable installation is greatly improved,

[0026] In the embodiment, the elastic contraction force of the elastic pleat damping air bag 2 is greater than that of the elastic pleat storage air bag 3, so that when the elastic pleat storage air bag 3 is not pressed by the threaded pressing ring 4, the gas in the elastic pleat damping air bag 2 flows back to the elastic pleat storage air bag 3, and thus the elastic pleat damping air bag 2 is compressed.

[0028] It should be noted that the fixing lug 6 is fixed by a screw, so that the sleeve socket 1 is installed and fixed, and when the cable passing through the sleeve socket 1 vibrates, the stability ring 7 on the sleeve frame 5 can effectively reduce the amplitude of the sleeve socket 1, and since the gap between the stability ring 7 and the sleeve frame 5 is fixedly embedded with a rubber block, the rubber block is an elastic structure, so it can effectively absorb part of the vibration force, thereby greatly improving the stability of the cable installation.

[0029] The working principle of the utility model discloses the power fitting with high stability is as follows:

[0030] The fixing lug 6 is fixed by screws, thereby installing and fixing the sleeve 1, and when the cable passing through the sleeve 1 is vibrated, the stabilizing ring 7 on the sleeve frame 5 can effectively reduce the amplitude of the sleeve 1, since the gap between the stabilizing ring 7 and the sleeve frame 5 is fixedly embedded with rubber blocks, and the rubber blocks are of elastic structure, thus part of the vibration force can be effectively absorbed, thereby greatly improving the stability of the cable installation, after the cable passes through the sleeve 1, the threaded abutting ring 4 on the two sides is rotated, so that the threaded abutting ring 4 is screwed into the direction of the abutting disc 11 along the outer threaded section 12, and after the elastic pleated gas storage air bag 3 is extruded by the threaded abutting ring 4, the gas in the elastic pleated gas storage air bag 3 quickly flows into the elastic pleated damping air bag 2, thus the elastic pleated damping air bag 2 is quickly filled and expanded, the expanded elastic pleated damping air bag 2 fills the gap between the cable and the sleeve 1, thereby tightly pressing and fixing the cable in the sleeve 1, since the expanded elastic pleated damping air bag 2 is of elastic structure, when the cable is shaken or swung due to wind force, the expanded elastic pleated damping air bag 2 can effectively reduce the swing amplitude of the cable, and when the sleeve 1 needs to be disassembled, the threaded abutting ring 4 is rotated in the opposite direction, so that the threaded abutting ring 4 no longer abuts against the elastic pleated damping air bag 2, at this time, the gas flow in the elastic pleated damping air bag 2 flows back to the elastic pleated gas storage air bag 3, thus the cable passing through the sleeve 1 can be quickly extracted, thereby the installation and disassembly of the sleeve 1 on the cable can be quickly realized, and the problem of cable loosening can be effectively avoided.
