Abstract
The utility model relates to an interference fit connecting bolt which comprises a screw and nuts. Threaded cylinders are arranged at two ends of the screw; the nuts are screwed on the threaded cylinders; the part of the screw, which is between the tail end of each threaded cylinder and the middle part of the screw adopts a cone, and the middle part of the screw is the large end of the cone; an internal taper sleeve matched with the cones is sleeved on the cones of the screw; and a through groove is formed on the internal taper sleeve in the axial direction. The connecting bolt is very convenient and easy to mount on and dismount from connected components and is time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of connecting bolt, particularly a kind of interference fit connecting bolt.
Background technique
Connecting bolt is the part that two parts are connected.For some parts, the bolt that connects bears bigger shear action in the process of transmitting torque, so bolt adopts the mode of interference to cooperate with connected component usually, shearing force is evenly distributed on each bolt, to avoid stress to concentrate, cause the connecting bolt fracture.But the mode of interference fit makes the installation and removal of bolt very difficult, and each installation or removal all need use bigger impact force that bolt is squeezed into or got, and very easily destroy the screw thread on the screw rod, and are not only time-consuming, and labor intensity is bigger.
Summary of the invention
The purpose of this utility model provides a kind of interference fit connecting bolt, makes the easy installation and removal of bolt on connected component easy.
Interference fit connecting bolt described in the utility model, comprise screw rod and nut, the two ends of screw rod are for offering threaded cylindrical body, nut is screwed on this threaded circular cylinder, screw rod is a cone between threaded circular cylinder end and screw rod middle part, and the screw rod middle part is the big end of cone, is set with the inner conical drogue that mates with cone on the cone of screw rod, and inner conical drogue offers groove vertically.
During installation, screw rod with bolt inserts in the bolt hole of connected component earlier, make an end of inner conical drogue also be arranged in bolt hole simultaneously, the other end of inner conical drogue then is positioned at outside the connected component end face, screw nut then, fit tightly until nut end face and connected component end face, then inner conical drogue by swelling between the bolt hole internal surface of the cone of screw rod surface and connected component, thereby make this connecting bolt and connected component interference fit.
During dismounting, nut is screwed off, then inner conical drogue restores to the original state after external force disappears, and inner conical drogue is withdrawed from from the bolt hole of connected component, takes out inner conical drogue and screw rod and gets final product.
The utility model makes the installation and removal of connecting bolt on connected component all very convenient easily, time saving and energy saving owing to have this kind structure.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the main pseudosection of interference fit connecting bolt described in the utility model;
Fig. 2 is the main pseudosection of inner conical drogue;
Fig. 3 is the right elevation of Fig. 2.
Two connected components are partly represented in double dot dash line among Fig. 1.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, this interference fit connecting bolt comprises screw rod 1 and nut 3, the two ends of screw rod 1 are for offering threaded cylindrical body, nut 3 is screwed on this threaded circular cylinder, screw rod 1 is a cone between threaded circular cylinder end and screw rod 1 middle part, and screw rod 1 middle part is the big end of cone, is set with the inner conical drogue 2 that mates with cone on the cone of screw rod 1, and inner conical drogue 2 offers groove 4 vertically.
