Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The figures are simplified schematic diagrams illustrating the basic structure of the invention in a schematic way only, and therefore they show only the components relevant to the invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to be referred must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; mechanical connection such as welding and the like can be adopted, and electrical connection can also be adopted; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The screw-in type preassembled cap nut shown in figures 1-6 is detachably connected in a round hole 10 of a lower tower cylinder 7 and comprises a hexagonal cap 1 and a mounting column 5, wherein the hexagonal cap 1 and the mounting column 5 are of an integral structure.

The surface of the mounting column 5 is provided with an external thread 6, and the inner wall of a round hole 10 of the lower tower tube 7 is provided with an internal thread matched with the external thread 6; the left side end face of the mounting column 5 is provided with a threaded hole 4 opposite to the external thread 6, the threaded hole 4 is communicated with the through hole 2, and the threaded hole 4 extends into the hexagonal cap 1; the external thread 6 and the internal thread are arranged for achieving the pre-installation purpose of the cap nut, and the hexagonal cap 1 is arranged for facilitating the cap nut to be screwed into the round hole 10 of the lower tower tube 7 by using a handle; the threaded hole 4 is arranged to be opposite to the external thread 6 so as to ensure that the cap nut rotates with the stud 8 after the stud 8 is screwed in and then the stud 8 is fastened, and the effect of fixing the cap nut can be achieved.

The diameter of the mounting column 5 is smaller than that of the hexagonal cap 1, so that pre-mounting can be easily carried out, and the assembly efficiency can be improved.

The diameter of the through hole 2 is larger than that of the threaded hole 4, so that the stud can conveniently enter the cap-shaped nut and can be matched with the threaded hole.

The width of external screw thread 6 is the same with the width of erection column 5, if external screw thread 6 width is too short, then can lead to the reduction of lid shape nut and tower section of thick bamboo joint strength down, can lead to lower tower bucket 7 round hole 10 to damage.

Example 1

As shown in fig. 1-3, a baffle 3 is fixedly connected to the inner wall of the head of the hexagonal cap 1, the baffle seals the outer end of the threaded hole, and the diameter of the baffle 3 is larger than that of the threaded hole 4; set up baffle 3 in hexagon cap 1 and separate screw hole and tower section of thick bamboo outward, can prevent that the rainwater from getting into in the screw hole.

Example 2

As shown in fig. 4-6, the left end of the hexagonal cap 1 is further provided with a convex cap 12, the convex cap 12 and the hexagonal cap 1 are of an integral structure, the convex cap seals the left end of the threaded hole 4, a cavity 11 is arranged inside the convex cap 12 to facilitate the processing of the threaded hole, and the diameter of the cavity 11 is larger than that of the threaded hole 4; the convex cap 12 is added to further improve the service life of the cap nut and prevent moisture and other corrosive impurities from entering the nut; the provision of the cavity 11 in the male cap 12 facilitates the machining of the threaded hole 4.

During installation, as the cap nut is provided with the external thread 6 on the surface of the installation column 5, the wrench applies torque through the cap nut hexagon cap 1 to screw the cap nut into the lower tower barrel screw round hole 10, so as to realize the pre-installation purpose. During assembly, the stud 8 is screwed in firstly, and then the fastening nut 9 is sleeved on the stud 8. in the process, when the thread of the stud 8 is matched with the threaded hole 4, the thread direction of the threaded hole 4 is opposite to that of the external thread 6, so that a reaction rotating torque is applied to the cap-shaped nut, the cap-shaped nut cannot be rotated under the action of the torque, and the purpose of preventing the cap-shaped nut from following rotation when the stud 8 or the fastening nut 9 is screwed in is achieved.

In light of the above, the present invention is not limited to the above embodiments, and various changes and modifications can be made by the worker without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
