technical field

The utility model relates to the field of mechanical connection, in particular to a tapered screw connection mechanism.

Background technique

If you want to connect two different objects, you must use the corresponding connection structure to achieve it. At present, the most used connection is the screw connection. The traditional threaded connection is generally connected by matching internal and external threads, which has the following defects: the two objects connected by the thread will rotate relative to each other under the action of external force, and the two objects that were originally connected together will eventually rotate as the rotation progresses. disconnected, causing the connection to fail.

Utility model content

To sum up, in order to overcome the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a tapered screw connection mechanism.

The technical solution of the utility model to solve the above-mentioned technical problems is as follows: a tapered thread connection mechanism, which is used to connect the first object and the second object, including the first connecting piece connecting the first object and the second connecting piece. a second connection part of the object, the first connection part and the second connection part are provided with connection ends connected to each other;

The connecting end of the first connecting piece is provided with a connecting hole covering the connecting end of the second connecting piece; the side wall opposite to the opening in the connecting hole is provided with a tapered stud extending downward, The position of the second connector corresponding to the tapered stud is provided with a tapered screw hole matching the tapered stud, and a notch is provided on the side wall of the tapered screw hole; the first connection The connecting end of the piece is sleeved behind the connecting end of the second connecting piece through the threaded connection of the tapered stud and the tapered screw hole, and the side wall of the tapered screw hole is also deformed and contracted to clamp the cone through the gap. shaped studs.

The beneficial effect of the utility model is: the connecting mechanism connects the two objects together, in addition to the threaded connection, it also generates a clamping force on the tapered stud so that the first connecting piece and the second connecting piece are not easy to rotate, thereby ensuring The objects connected together will not be separated, and the connection is reliable and stable.

On the basis of the above-mentioned technical scheme, the utility model can also be further improved as follows:

Further, the connecting hole is provided with an internal thread, and the outer wall of the connection end of the second connecting piece is provided with an external thread matching the internal thread.

The beneficial effects of adopting the above further technical solution are: increasing the number of threaded connections to strengthen the connection, and in addition, it is easy to deform and shrink the side wall of the tapered screw hole through the gap to clamp the tapered stud.

Further, the height of the notch is the same as the height of the tapered screw hole.

Further, there are four notches, and the four notches are evenly distributed on the side wall of the tapered screw hole.

The beneficial effect of adopting the above further technical solution is: the clamping force of the side wall of the tapered screw hole on the tapered stud is enhanced.

detailed description

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

As shown in Figure 1, a tapered thread connection mechanism is used to connect the first object 1 and the second object 2, including the first connecting piece 3 connecting the first object 1 and the second object 2 The second connecting piece 4, the first connecting piece 3 and the second connecting piece 4 are provided with connecting ends connected to each other.

The connecting end of the first connecting piece 3 is provided with a connecting hole 5 that covers the connecting end of the second connecting piece 4; the side wall opposite to the opening in the connecting hole 5 is provided with a cone extending downward. shaped stud 6, the position of the second connector 4 corresponding to the tapered stud 6 is provided with a tapered screw hole 7 matched with the tapered stud 6, and the side wall of the tapered screw hole 7 There is a gap 8; the connection end of the first connector 3 is sleeved behind the connection end of the second connector 4 through the threaded connection of the tapered stud 6 and the tapered screw hole 7, and the tapered screw The side wall of the hole 7 also deforms and shrinks the tapered stud 6 through the notch 8 . When the first object 1 and the second object 2 are to be connected, the connecting end of the first connecting part 3 is enclosed within the connecting end of the second connecting part 4, because the connecting end outer wall of the second connecting part 4 There is an external thread matched with the internal thread of the connecting hole 5, and it is sufficient to rotate the first connecting piece 3 and the second connecting piece 4 relatively. When the connecting end of the first connecting piece 3 is threaded outside the connecting end of the second connecting piece, the tapered stud 6 is also screwed into the tapered screw hole 7 . As the tapered stud 6 is threaded into the tapered screw hole 7, the depth becomes deeper, under the action of the notch 8, the connecting hole 5 will hold the side wall of the tapered screw hole 7 tightly, and the tapered stud 6 will move toward the tapered screw hole 7. The tapered screw hole 7 is stretched outward, and finally the side wall of the tapered screw hole 7 deforms and shrinks through the gap 8 to tightly clamp the tapered stud 6 . To sum up, the connecting mechanism connects the two objects together in addition to the threaded connection, and also produces a clamping force on the tapered stud 6 so that the first connecting part 3 and the second connecting part 4 are not easy to rotate, thereby ensuring The objects connected together will not be separated, and the connection is reliable and stable.

Preferably: the gap 8 is provided with four, and the four gaps 8 are evenly distributed on the side wall of the tapered screw hole 7, and the height of the gap 8 is the same as the height of the tapered screw hole 7 Similarly, the above design strengthens the clamping strength of the side wall of the tapered screw hole 7 to the tapered stud 6, further improving the reliability of the connection.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
