Description

Novel screw sleeve

Technical Field

The utility model relates to an automobile parts technical field, concretely relates to novel swivel nut.

Background

The installation that relates to panel etc. in the automobile assembling process generally needs to use the swivel nut, but the restricted cost requirement of conventional swivel nut, and the non-high-quality material preparation of material when receiving the impact at the automobile in-process of traveling can arouse the deformation of swivel nut chamber wall screw thread, causes the panel to be difficult for separately, causes the maintenance inconvenience, and if adopt high-quality material preparation then the cost of swivel nut is high, and market competition descends, needs the improvement.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical defect, the utility model provides a following technical scheme:

novel swivel nut, including main part and screw thread reference column, the tail end at the screw thread reference column is fixed to the main part, and the external diameter of screw thread reference column is less than the external diameter of main part, and runs through out the mounting hole along the axial of main part and reference column, and the internal thread is established for three-section ladder type hole and first section pore wall to the mounting hole, still includes location cap, inside lining, and the inside lining is located the middle section mounting hole and inside lining tail end butt mounting hole tail section step face, and the location cap spiro union is at mounting hole first section and butt inside lining, and the inside lining sets up the screw thread for barrel.

The improved structure of the screw sleeve fixes the lining by matching the positioning cap with the stepped hole, the lining is made of high-quality materials, the lining is a cylinder body, the inner wall of the cylinder cavity is provided with threads for butting the stud, and the screw sleeve has stable structure, impact resistance and lower cost.

Furthermore, a plurality of grooves are arranged on the wall of the first end cylinder of the lining at intervals, wherein the outer walls of at least two cylinders at opposite positions are provided with lugs, and the hole wall of the corresponding mounting hole is provided with a positioning hole so that the lugs and the positioning hole are matched for auxiliary positioning to improve the structural stability.

Furthermore, the main body and the positioning column are integrally formed, threads are arranged on the column body between the head end and the tail end of the positioning column, and the outer diameter of the column body at the tail end is smaller than that of the threaded section, so that the screw connection is facilitated.

Furthermore, the outer wall of the tail end of the positioning column is provided with a groove, so that the positioning is convenient.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the thread insert has the advantages of improved structure, impact resistance and lower cost.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

FIG. 1 is a sectional view of the present insert;

FIG. 2 is an external view of the present insert;

wherein the reference numerals are:

1. a main body; 2. a positioning column; 3. a liner; 4. a positioning cap; 5. a bump; 6. a groove; 7. and (7) positioning the holes.

Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Example 1

Referring to fig. 1 and 2, a main body 1 and a threaded positioning post 2 of the novel threaded sleeve are integrally formed, the main body is located at the tail end of the threaded positioning post, a post body between the head end and the tail end of the positioning post is threaded, the outer diameter of the post body at the tail end is smaller than that of the threaded section, and a groove 6 is formed in the outer wall of the tail end of the positioning post for convenient positioning.

The main part is the plate body, like hexagon, circular etc. the external diameter of screw thread reference column is less than the external diameter of main part, and runs through division mounting hole along the axial central line of main part and reference column, and the mounting hole is tertiary notch cuttype, divides the three-section, reduces from preceding back aperture gradient, and the internal thread is opened to first section pore wall, and well back end is the smooth section.

In this embodiment, still include position cap, inside lining, wherein inside lining 3 is high-quality alloy preparation, and is shock-resistant, and position cap 4 is the T type, and the horizontal end outer wall is threaded, meshes with the screw thread of mounting hole first section mutually, and the inside lining is the barrel and is located the middle section of mounting hole, and the tail end and the mounting hole tail section step face, boundary chamber wall butt promptly, the horizontal end butt of head end and the position cap of inside lining, and the same screw thread of opening of inside lining section of thick bamboo inner wall is in order to butt joint double-screw bolt etc..

In addition, in this embodiment, a plurality of grooves are spaced on the wall of the first end of the lining, so as to divide the wall of the lining into separate bodies, two separate bodies, namely the cylinder bodies, which are in opposite positions are selected, the outer wall of each separate body is provided with a bump 5, the wall of the corresponding mounting hole is provided with a positioning hole 7, and the bump and the positioning hole are matched for auxiliary positioning, so that the structural stability is enhanced.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
