Abstract
The application discloses double-end screw thread fastener, including cylindric body, cylindric body both ends are provided with the screw thread, still include cylindric laminating post, the laminating post sets up in an end of body, the diameter of laminating post is not more than the diameter of body, the axial lead of laminating post and the axial lead of body are on a straight line. The utility model discloses following beneficial effect has: through set up the laminating post in body one end, increase the contact surface of body and laminating post for the cooperation is inseparabler between body and the laminating post, can not take place to become flexible.
Description
Technical Field
The utility model relates to a fastener field especially relates to a double thread fastener.
Background
Fig. 1 is a schematic view showing the structure of a conventional stud, because both ends of the conventional stud are completely identical, and fig. 2 is a schematic view showing the method of using the conventional stud, because one end of the conventional stud needs to be completely embedded into the fastening body (2), and as shown in fig. 2, a gap (1) exists between the stud and the fastening body 1(2), and the existence of the gap can cause the stud to be easily loosened.
SUMMERY OF THE UTILITY MODEL
The utility model provides a to above-mentioned problem, a double thread fastener is proposed.
The utility model adopts the following technical scheme:
the utility model provides a double-end screw thread fastener, includes cylindric body, cylindric body both ends are provided with the screw thread, still include cylindric laminating post, the laminating post sets up in an end of body, the diameter of laminating post is not more than the diameter of body, the axial lead of laminating post and the axial lead of body are on a straight line.
Because the existence of laminating post in the present case, when body one end embedding fastening body in, the laminating post is almost totally in the same place with the fastening body laminating, because the existence of laminating post, the space between body and the fastening body reduces by a wide margin for cooperation between body and the fastening body screw is inseparabler, and the difficult emergence of body is rocked, and not hard up can not take place for the cooperation between body and the fastening body.
This device is through setting up the laminating post in body one end, increases the contact surface of body and laminating post for the cooperation is inseparabler between body and the laminating post, can not take place not hard up.
Optionally, the body further comprises a polygonal column, and the polygonal column and the fitting column are respectively arranged at two ends of the body.
Because only one end of the body is completely embedded into the fastening body, and the other end of the body is exposed outside, the polygonal column is arranged at the end where the attaching body is not arranged, and the polygonal column in the scheme is hexagonal in priority, so that the wrench is convenient to operate.
Optionally, the thread is a male thread or a female thread.
Optionally, the screw thread is a male screw thread, and the diameter of the fitting column is equal to the diameter of the body.
Optionally, the thread is a female thread, and the diameter of the fitting column is equal to the diameter of the body.
The utility model has the advantages that: through set up the laminating post in body one end, increase the contact surface of body and laminating post for the cooperation is inseparabler between body and the laminating post, can not take place to become flexible.
Description of the drawings:
FIG. 1 is a schematic diagram of a conventional stud construction;
FIG. 2 is a schematic illustration of a conventional stud use method;
FIG. 3 is a schematic diagram of a double-start threaded fastener;
fig. 4 is a schematic view showing the fitting relationship between the double-start screw fastening device and the fastening body.
The figures are numbered: 1. gap, 2, fastening body, 201, tapered cavity, 3, body, 4, laminating body, 5, polygonal column, 6, screw thread.
The specific implementation mode is as follows:
the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 3, a double-thread fastening device includes a body 3, a fitting body 4 and a polygonal column 5, wherein the fitting body 4 and the polygonal column 5 are respectively disposed at two ends of the fitting body 4, male threads 6 are disposed at two ends of the body 4, the diameter of the fitting body 4 is equal to that of the body 3, and the axial line of the fitting body 4 and the axial line of the body are on the same straight line.
The structure of double thread fastener when using on the fastening body 2 is shown in figure 4, because the existence of the laminating body 4, only one toper chamber 201 is in the clearance of body 1 and fastening body 2, for the clearance in figure 2, the clearance of body 3 and fastening body 2 reduces by a wide margin behind the setting laminating body 4, and body 1 is inseparabler with the cooperation of fastening body 2, and difficult appearance is not hard up.
The above only is the preferred embodiment of the present invention, not therefore the limit the patent protection scope of the present invention, all applications the equivalent structure transformation made by the contents of the specification and the drawings of the present invention is directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
