[0002] The screw sleeve with external thread is usually used to cooperate with the shaft of the polished rod, and is fixed on the shaft so that the shaft has the function of threaded connection; the shaft sleeve has a variety of specifications, which can be selected according to the needs, and has certain versatility. It is removable and easy to use; the screw sleeve and the shaft generally need to cooperate with the structure of the groove and the convex edge, so that the screw sleeve will not rotate relative to the shaft and ensure the stability of the connection, but this connection method needs to be on the shaft or The structure of grooves and ribs is processed on the screw sleeve, which leads to low processing efficiency and increases processing cost

Embodiment Construction
[0011] The present invention is described below in conjunction with accompanying drawing.
[0012] as attached figure 1 As shown, a screw sleeve tight connection structure described in the present invention includes a shaft body 1, a shaft head 2, a screw sleeve 3 and a connecting screw 4; the shaft head 2 is connected to one end of the shaft body 1 through a shaft shoulder 5 , the screw sleeve 3 cooperates with the shaft head 2, and is connected and fixed with the shaft head 2 through the connecting screw 4; the diameter of the shaft body 1 is equal to the outer diameter of the screw sleeve 3, when the screw sleeve 3 is matched with a deeper threaded hole , the shaft body 1 can be screwed in with the screw sleeve 3 without restricting the movement of the screw sleeve 3; the outer circumference of the shaft head 2 is provided with knurling with a textured structure, and the shaft head 2 interferes with the screw sleeve 3 through the knurling Cooperate, because knurling is a c...

The invention discloses a tight connecting structure for a thread sleeve. The tight connecting structure comprises a shaft body, a shaft head, the thread sleeve and a connecting screw. The shaft head is connected to one end of the shaft body through a shaft shoulder. The thread sleeve is matched with the shaft head, and is fixedly connected with the shaft head through the connecting screw. Knurling is arranged on the outer circumference of the shaft head, and the shaft head is in interference fit with the thread sleeve through the knurling. The shaft shoulder is in the shape of a circular truncated cone. The free end of the thread sleeve is matched with the shaft shoulder. According to the tight connecting structure for the thread sleeve, the shaft head is in interference fit with the thread sleeve through the knurling and is matched with the connecting screw to fix the thread sleeve, so that relative rotation of the thread sleeve and the shaft head is avoided; the knurling can be selected to be of a textured structure so that gripping force can be increased; the free end of the thread sleeve is matched with the shaft shoulder, the thread sleeve can be further fixed, and the overall structure is stable; due to the convenience of knurling machining, machining efficiency is improved, and machining cost is reduced.
