Abstract
The utility model discloses a manual operation shaft-pulling device which comprises a pull rod with an external screw thread at one end. The manual operation shaft-pulling device further comprises a transitional joint which comprises a screw sleeve and a screw column which is matched with a screw thread of an internal screw thread hole of a hinge pin. The screw sleeve is provided with an internal screw thread hole which can be detachably connected with an external screw thread end of the pull rod. The screw column is integrally placed or fixedly connected or assembled at one end of the screw sleeve in a thrust mode through a stop-and-block structure. In the process of using, when the internal screw thread of the hinge pin is different, the hinge pin is connected with the pull rod through the transitional joint, the screw column on the transitional joint is connected with the internal screw thread hole on the hinge pin in a matched mode, and the screw sleeve on the transitional joint is connected with the screw thread at the external screw thread end of the pull rod. Another set of tools is not required to be replaced, the manual operation shaft-pulling device is convenient and light to carry, and cost is greatly saved.
Description
Technical field
The utility model relates to a kind of manual dismounting bearing pin or the device of power transmission shaft.
Background technology
Detaching device for pin shaft of the prior art such as Chinese patent notification number are CN201760849U, the day for announcing is on March 16th, 2011, name is called in " a kind of detaching device for pin shaft " specification and discloses a kind of detaching device for pin shaft, comprise pull bar, impact sleeve, one end of pull bar is provided with the external screw thread that cooperates for the bearing pin screwed hole, the other end is provided with buting iron, the center of impact sleeve is provided with the through hole with the pull bar matched in clearance, the periphery of impact sleeve is provided with handle, detaching device for pin shaft of the prior art can only be dismantled the bearing pin that internal thread hole cooperates with the external screw thread spiral of pull bar, when if the external screw thread of the internal thread hole on the bearing pin and pull bar is mismatched, need to change another set of detaching device for pin shaft, the detaching device for pin shaft versatility is poor, has increased production cost.
The utility model content
The purpose of this utility model is to provide a kind of manual Shaft drawer that can be common to preferably the different bearing pin of internal thread hole size.
For achieving the above object, the utility model adopts following technical scheme: a kind of manual Shaft drawer, comprise that an end is provided with externally threaded pull bar, this manual Shaft drawer also comprises transit joint, described transit joint comprises swivel nut, be used for bearing pin on the double-screw bolt of internal thread hole threaded engagement, swivel nut has the internal thread hole with the male end releasable connection of pull bar, and described double-screw bolt is wholely set or is fixedly connected with or be assemblied in by the Stop structure thrust end of swivel nut.
Described double-screw bolt is a switching bolt, the switching bolt is assemblied in an end of swivel nut by the Stop structure thrust, described Stop structure comprises that an end of swivel nut turns over the gear edge that cooperates with the lower surface block of the nut of the bolt of transferring of establishing after the screw portion of switching bolt is outwards passed by the internal thread hole of swivel nut.
A kind of manual Shaft drawer of the present utility model, in use, if the internal thread hole on the bearing pin is not simultaneously, only need by transit joint bearing pin to be connected with pull bar, double-screw bolt on the transit joint and the internal thread hole on the bearing pin are connected, and the swivel nut on the transit joint is threaded with the male end of pull bar, does not need to change another set of instrument, carrying portable has been saved cost greatly.
Further, the double-screw bolt of setting is the switching bolt of head on swivel nut, has further saved cost, for the bearing pin of different internal thread hole sizes, only needs to change the switching bolt and gets final product.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the cutaway view of the transit joint among Fig. 1;
Fig. 3 is the use view of embodiment of the present utility model.
The specific embodiment
A kind of embodiment of manual Shaft drawer, as shown in Figure 1, comprise pull bar 1, one end of pull bar 1 is provided with external screw thread, the other end of pull bar 1 is provided with buting iron 2, the gap is equipped with impact sleeve 3 on the pull bar 1, this manual Shaft drawer also comprises transit joint 4 as shown in Figure 2, transit joint 4 comprises swivel nut 41, be used for bearing pin on the double-screw bolt of internal thread hole threaded engagement, described double-screw bolt is a switching bolt 43, swivel nut 41 has the internal thread hole 411 with the male end releasable connection of pull bar 1, switching bolt 43 is assemblied in an end of swivel nut 41 by the Stop structure thrust, described Stop structure comprises that an end of swivel nut 41 turns over the gear that cooperates with the lower surface block of the nut of the bolt 43 of transferring established along 412 after the screw portion of switching bolt 43 is outwards passed by the internal thread hole 411 of swivel nut 41.
Above-described embodiment cooperates with the pull bar external screw thread just such as the internal thread hole of pin roll end face in use, then need not to use transit joint, impact sleeve is enclosed within on the pull bar, and then male end and the bearing pin threaded engagement of pull bar tightened, the hand-held impact cover is exerted oneself backward, relies on inertia that bearing pin is extracted; If the external screw thread of the internal thread hole of pin roll end face and pull bar is mismatched, then need to use transit joint, as shown in Figure 3: first the switching bolt on the transit joint is connected with the internal thread hole of bearing pin, again the internal thread hole of pull bar male end with the transit joint swivel nut is connected, the hand-held impact cover is exerted oneself backward, relies on inertia bearing pin can be extracted.
In other embodiments, the externally threaded boss that the outer peripheral face that described double-screw bolt can also be convexly equipped with by an end one of swivel nut is provided with the internal thread hole threaded engagement of bearing pin consists of, when carrying, can carry different transit joints, with convenient the bearing pin of the different internal thread hole of size be dismantled.
