Sheath connecting structure of combined cables

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0019] Reference Figure 1-3 , The sheath connection structure of the combined cable includes a jacket 1, the jacket 1 is inserted with an inner jacket 2, the inner wall of the jacket 1 is provided with an annular groove 3, and the inner wall of the annular groove 3 is rotatably connected with a plurality of levers 4 A compression spring 5 is fixedly connected between each abutment rod 4 and the inner wall of the annular groove one 3. The outer wall of the inner sleeve 2 is provided with an annular groove two 6. It is further explained that the abutment rod 4 is inserted into the annular groove two 6 The internal compression spring 5 is not fully expanded to ensure the elastic force to fix the inner sleeve 2. A number of semicircular blocks 8 are fixed on the inner wall of the annular groove 2 6, the number of the push rod 4 is three, and the number of semicircular blocks 8 is Three. The radius of the semicircular block 8 matches the depth of the second ring groove 6, to ensure that the push rod 4 is not located in the second ring groove 6 when the semicircular block 8 pushes up the push rod 4, which facilitates the subsequent extraction of the inner sleeve 2 Work, rounded corners 7 are provided on the inner walls of both sides of the second ring groove 6, and the rounded corners 7 are set to make the connection between the push rod 4 and the second ring groove 6 smoother, which is convenient for the push rod 4. When connecting with the inner sleeve 2, insert the inner sleeve 2 into the outer sleeve 1. The inner sleeve 2 first contacts the push rod 4, squeezes the push rod 4 to rotate in the annular groove 1-3, when the inner sleeve 2 moves to the ring shape When the groove 2 6 is opposite to the abutment rod 4, the abutment rod 4 is bounced and snapped into the annular groove 2 under the reverse elastic force of the compression spring 5 to complete the fixing of the inner sleeve 2.

[0020] When disassembling the inner sleeve 2, rotate the inner sleeve 2 until the semicircular block 8 is in contact with the push rod 4, and the semicircular block 8 squeezes the push rod 4 and rotates to the outside and retracts into the annular groove 1-3 to complete the pulling of the inner sleeve 2. Out.

[0021] The inner wall of the outer casing 1 is fixed with a sealing sleeve 9. The sealing sleeve 9 can be made of rubber. The end of the sealing sleeve 9 away from the outer casing 1 is provided with an annular groove three 10, and the inner wall of the annular groove three 10 is integrally formed with an inward turning Flanging 11, the height of the flanging 11 gradually decreases from the inside to the outside, and the flanging 11 is inclined to the inside. It is further explained that the distance of the inner diameter of the inner end of the flanging 11 matches the diameter of the inner sleeve 2, so the inner diameter of the outer end of the flanging 11 is smaller than the inner diameter With the diameter of the sleeve 2, the sealing sleeve 9 is tightly pressed against the inner sleeve 2 through the elastic deformation of the flange 11 when the inner sleeve 2 is inserted to complete the sealing work.

[0022] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it may be welding, gluing, or integral molding arrangement, which is well known to those skilled in the art.

[0023] The operating principle of the present invention is now explained as follows:

[0024] When connecting the inner sleeve 2 and the outer sleeve 1, insert the inner sleeve 2 into the outer sleeve 1. The inner sleeve 2 first contacts the push rod 4, and the push rod 4 is squeezed to rotate into the annular groove 1-3. When the inner sleeve 2 When moving to the position of the second ring groove 6 and the push rod 4, under the reverse elastic force of the compression spring 5, the push rod 4 is bounced and snapped into the second ring groove 6. When the semicircular block 8 collides with the push rod 4, Rotate the inner sleeve 2 to stagger the semicircular block 8 and the abutment rod 4, so that the abutment rod 4 can be inserted into the annular groove 2 to complete the fixing of the inner sleeve 2, and a sealing sleeve 9 is set at the connection between the inner sleeve 2 and the outer sleeve 1. In the sealing work, the folded edge 11 on the sealing sleeve 9 is turned inward to be tightly pressed against the outer wall of the inner sleeve 2 to complete the sealing work.
