Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

At present, a rod body of a cylinder with a spiral groove cut on the outer surface or a cone with a conical spiral groove cut on the outer surface is generally called a screw rod 200, meanwhile, a part of the cylinder with the spiral groove cut on the inner surface or the cone with the conical spiral groove cut on the inner surface is called a nut 100, and the screw rod 200 and the nut 100 are matched to form a threaded structure for converting rotary motion into linear motion. Generally, the screw thread of the screw rod 200 is exposed, and it is difficult to avoid the damage to the screw thread from the outside.

In order to solve the above technical problems, the present embodiment discloses a thread-concealed screwing structure, which is shown in fig. 1 to 3, and includes a screw rod 200 and a nut 100, wherein the outer side wall of the nut 100 is provided with anti-slip threads to increase the operation hand feeling of the nut 100; the inside wall of nut 100 is equipped with spiral helicine first recess 101, the lateral wall of screw rod 200 is equipped with the second recess 201 that corresponds with first recess 101, the groove 300 is established with the laminating formation of the opening of second recess 201 to the opening of first recess 101, it has at least one sliding part or at least one rolling member 301 to hold swing joint in the groove 300.

Specifically, the utility model discloses a hidden spiro union structure of screw thread, the lateral wall that is equipped with spiral helicine first recess 101 and screw rod 200 through the inside wall at nut 100 is equipped with the second recess 201 that corresponds with first recess 101, first recess 101 forms with the cooperation of second recess 201 and holds and establish groove 300, hold and establish groove 300 in swing joint have at least one sliding part or at least one rolling member 301 simultaneously, when screwing nut 100, sliding part or rolling member 301 can contradict respectively in the upper end of second recess 201 or the lower extreme of second recess 201 according to the direction of screwing of nut 100, because sliding part or rolling member 301 can't move along the farther department of second recess 201 again, sliding part does the slip of relative rest or rolling member 301 holds and establishes the groove 300 and does the rotation of relative rest, screw rod 200 then does the reciprocating under the effect of sliding part or rolling member 301, thereby realize the same lift drive effect with traditional screw rod 200. Because the utility model discloses a screw rod 200 does not have the screw thread to expose, can furthest play the guard action to the screw thread when accomplishing that the appearance is more pleasing to the eye, increase of service life.
