Preferably, first seal groove, which is arranged, screws portion and the described first externally threaded junction in the connector.
Preferably, second seal groove is arranged in the nut driving portion and the externally threaded junction of the third.
Preferably, the limiting stand is annular convex platform.
Preferably, the material of the gasket is silica gel or rubber.
By adopting the above technical scheme, due to the externally threaded setting of third on the nut other end, so that the utility model is anti-
Water swivel can not only increase waterproof effect to being connected directly between in equipment, it is ensured that under two direct-connected operating conditions of equipment
Waterproof connector installation convenience and economy；The setting of gasket, thereon taper and limiting stand, so that nut is tightened
When, the cable inside waterproof connector is firmly sealed up, is further improved anti-under taper hole extrusion deformation effect by gasket
The sealing effect of water swivel.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1-3, a kind of Novel water-proof joint, including joint body 1, gasket 2 and nut 3, joint body 1,
Gasket 2 and nut 3 are hollow structure, so that cable can pass through；One end of joint body 1 be equipped with the first external screw thread 11,
The other end is equipped with the second external screw thread 12, and 3 one end of nut is equipped with second internal screw thread 31 compatible with the second external screw thread 11, the other end
Equipped with third external screw thread 32；Gasket 2 is cylinder, and gasket 2 is located in joint body 1 and nut 3,2 one end of gasket
The inner wall of outer wall and 1 other end of joint body is tapered surface, and the two is provided with identical taper；It is set on the inner wall of nut 3
There is limiting stand 33, the internal diameter of limiting stand 33 is less than the internal diameter of gasket 2.
Wherein, because joint body 1 with nut 3 is connect with equipment, in order to guarantee sealing effect, the first external screw thread
