DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] Example: See Figure 1 The utility model provides a technical solution: a cable sheath waterproof plastic seal.

[0025] Among them, an insert block 101 is fixedly connected to the edge of one side of the baffle 1, a slot 102 is opened at the edge of the other side of the baffle 1, a threaded hole 108 is opened at the connection position of the insert block 101 and the slot 102, two through-holes 104 are symmetrically opened on the front of the baffle 1, and a cable passage cavity 103 is opened from the through-hole 104 to the side, an inner pressure block 107 is provided near the threaded hole 108 on the back of the baffle 1, an outer pressure block 106 is provided outward of the inner pressure block 107, and a pressure block side plate 109 is fixedly connected to the outside of the outer pressure block 106 on the back of the baffle 1, and a sheath insertion hole 110 is opened on the outside of the pressure block side plate 109 on the back of the baffle 1, and the sheath 4 is inserted into the sheath insertion hole 110.

[0026] In this embodiment, the baffle 1 is a quarter circle, and the four baffles 1 can be assembled into a full circle. The corresponding plug-in blocks 101 are inserted into the slots 102 to fix them. Before the baffles 1 are spliced, the cable cavity 103 is aligned with the cable 3, and the cable 3 is inserted into the cable cavity 103 and moved into the through-hole 104. The cable 3 can be installed in the through-hole 104 without passing one end of the cable 3 through the through-hole 104. The inner pressure block 107 and the outer pressure block 106 are respectively provided with semicircular holes at the joints, and the semicircular holes are aligned with the through-hole 104 and squeeze the cable 3, thereby blocking the through-hole 104. The outer pressure block 1 06 is fitted on the pressure block side plate 109, and the inner pressure block 107 is fitted on the outer pressure block 106. When the screw cover 2 is rotated into the center threaded hole 108, the inner pressure block 107 is squeezed by the end of the screw cover 2, and the semicircular hole at the perforation 104 is reduced to block the compression cable 3. In the same way, a baffle 1 is set at the other end of the cable 3, and the sheath 4 is inserted between the two baffles 1. The sheath 4 is aligned with the sheath insertion hole 110 at the edge of the baffle 1, and finally the installation of the entire seal is completed. External water cannot enter the interior of the seal from the sheath 4, so that the cable 3 will not be soaked in water, avoiding rot and short circuit.

[0027] Rubber pads 105 are provided on both sides of the cable passage cavity 103 .

[0028] In this embodiment, the rubber pad 105 is made of soft material and fits the edge of the cable 3 entering the cable cavity 103 . The cable 3 needs to be pulled to enter the through hole 104 . At the same time, it also prevents the cable 3 in the through hole 104 from escaping and being pulled back into the cable cavity 103 .

[0029] The edge of the inner pressure block 107 close to the threaded hole 108 is tilted inward.

[0030] In this embodiment, as the screw cap 2 is screwed inward, the more the inner pressure block 107 extends, the greater the force of squeezing the inner pressure block 107 by the screw cap 2, and the tighter the inner pressure block 107 cooperates with the outer pressure block 106 to block the gap of the perforation 104, thereby preventing external water from entering the interior of the sheath 4 through the perforation 104.

[0031] The sheath 4 is formed by splicing two semicircular sleeves.

[0032] In this embodiment, the sheath 4 is spliced ​​together like the baffle 1 and is fixed by inserting both ends into the sheath insertion holes 110 on the baffle 1, without having to pass the cable 3 through the sheath 4 in advance.

[0033] A handle 201 is fixedly connected to the front of the screw cap 2 .

[0034] In this embodiment, the handle 201 is protruded from the surface of the baffle 1 , so that the operator can conveniently hold the handle 201 to rotate the screw cap 2 .

[0035] Working principle: first align the cable passage cavity 103 on the corresponding baffle 1 with the cable 3, and the cable 3 is inserted into the cable passage cavity 103 and moved into the through-hole 104. Each cable 3 is fixed in the through-hole 104. The installed baffle 1 is combined by inserting the corresponding plug-in block 101 into the slot 102. The four baffles 1 are pieced together to form a whole circle. The semicircular hole combination at the joint of the inner pressure block 107 and the outer pressure block 106 is aligned with the through-hole 104 and passes through the cable 3. When the screw cover 2 is rotated into the center threaded hole 108, the inner pressure block 107 is squeezed by the end of the screw cover 2, and the semicircular hole at the through-hole 104 is reduced to block and compress the cable 3. In the same way, a baffle 1 is set at the other end of the cable 3, and the sheath 4 is inserted between the two baffles 1. The sheath 4 is aligned with the sheath insertion hole 110 at the edge of the baffle 1, and finally the installation of the entire seal is completed.
