Description

A occupy-place bolt for nail hole rubber coating Technical Field The utility model relates to the technical field of aviation sealant construction, in particular to a space occupying bolt for nail hole gluing. Background With the development of modern industry, the requirements on the machining precision of mechanical parts are higher and higher. In many fields, such as aerospace, automotive manufacturing, precision instruments, etc., it is often necessary to brush some installed parts with a sealant to provide water resistance, corrosion resistance, thermal insulation, etc. The space occupying bolt is an auxiliary tool specially designed for a nail hole gluing scene, is mainly used for accurately positioning the position of the nail hole in the gluing process, preventing glue from overflowing or coating unevenly, and reserving a standard aperture for subsequent installation (such as screw and rivet fixing). The core function of the device is to ensure the accuracy and normalization of the gluing area through physical occupation, and improve the reliability of the assembly process. At present, in the gluing process of a multi-screw hole part, because holes are more, when a space occupying screw is not used, sealant is easy to permeate into the screw hole, so that a screw hole is blocked, and the screw hole is difficult to clean, so that the screw hole is occupied and protected by a common space occupying screw, but the surface of a workpiece is also brushed with the sealant because the sealant is coated on the surface of the space occupying screw, so that the sealant is brushed, and when the sealant is solidified, the sealant can block a groove on a screw cap, so that the space occupying screw is difficult to remove, and the gluing process is more troublesome. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides the space occupying bolt for gluing the nail hole, and the space occupying bolt adopts a mode of combining the screw and the screw sleeve, so that the technical effects that the taking out of the space occupying bolt is not affected when the sealant is painted and the screw thread is prevented from being blocked by the sealant are realized. In order to solve the technical problems and achieve the technical effects, the utility model is realized by the following technical scheme: The technical scheme of the utility model is that the space occupying bolt for gluing nail holes comprises an upper screw assembly and a lower screw sleeve assembly, wherein the upper screw assembly comprises a screw column, a screw cap is arranged at the top of the screw column, a groove is formed in the upper surface of the screw cap, and a stud is arranged at the bottom of the screw column; the lower part silk cover subassembly is including the cover to be established the lantern ring on screw post surface, the bottom of lantern ring be provided with the screw thread section of thick bamboo of double-screw bolt surface looks adaptation, the draw-in groove has all been seted up to the both sides on lantern ring surface, the glue discharging mouth has been seted up to the bottom of screw thread section of thick bamboo. Further, the grooves are arranged in a plum blossom shape. Further, the thickness of the groove is the same as the height of the nut. Further, the length of the stud is the same as the length of the threaded cylinder. Further, the diameter of the threaded cylinder is larger than the diameter of the screw column. Further, the diameter of the nut is larger than the diameter of the threaded cylinder. Further, the top of the nut is of smooth design. Further, the depth of the clamping groove is the same as the thickness of the lantern ring, and the two clamping grooves form a straight groove. Further, the diameter of the threaded cylinder is the same as the diameter of the collar. The sealing device has the beneficial technical effects that the upper screw assembly and the lower screw sleeve assembly are assembled through the arrangement of the upper screw assembly and the lower screw sleeve assembly when in use, the upper screw assembly and the lower screw sleeve assembly are assembled and screwed into holes to be glued together, then the upper screw assembly is taken down, the gluing work is carried out on the surface of a workpiece, when the sealing agent is painted on the surface of the lantern ring, the sealing agent can enter the inner wall of the threaded cylinder and can not enter the inner wall of the screw hole, compared with the traditional space occupying screw, because the top of the lower screw sleeve assembly is not sealed, after the sealing agent is solidified, a worker can insert a groove through a hexagonal wrench and turn a nut, so that after the upper screw assembly is screwed into the lower screw sleeve assembly, the device is taken out integrally, the original screw hole is exposed, the situation that the sealing agent is painted above the space occu
