Abstract
The utility model discloses a kind of screwed coupling, comprise cylindrical body, the outer wall of described body is provided with connection tooth, axis hole A and axis hole B is respectively arranged with in the two ends of described body, described axis hole A is communicated with axis hole B by through hole, the inwall of described through hole is provided with screw thread, step is provided with in described axis hole B, axis hole B is divided into hole A and hole B by described step, the diameter of described hole A is less than hole B, in described axis hole A, be provided with the bolt that one end penetrates axis hole A, the other end of described bolt is provided with outer six square toes.The utility model has structure advantage simple, easy to operate, with low cost, it is adopted to carry out fast connecting and dismantling, prevent in unloading process, damage the generation of phenomenon, meanwhile, owing to having hole A, when dismantling, there is buffer area, dismantle more laborsaving, reduce labor intensity, improve working efficiency.
Description
Technical field
The utility model relates to a kind of coupling, particularly a kind of screwed coupling.
Background technique
The utility model patent that a kind of name is called " a kind of coupling " is disclosed in CN102889306A, it comprises housing, two ends in described housing are respectively equipped with an axis hole, and be provided with a through hole between described two axis holes, the diameter of described through hole is less than the diameter of axis hole.Although the coupling of this structure can carry out the connection of axle and axle, but, the coupling of this structure is not quick detachable, in unloading process, need to use hammer and carry out beaing coupling and coupling could be dismantled, do like this and easily coupling is struck bad, cause spoilage higher,, also comparatively require great effort meanwhile, add working strength.
Model utility content
The purpose of this utility model is just to provide a kind of screwed coupling for convenience detach.
The purpose of this utility model is realized by such technological scheme, a kind of screwed coupling, comprise cylindrical body, the outer wall of described body is provided with connection tooth, axis hole A and axis hole B is respectively arranged with in the two ends of described body, described axis hole A is communicated with axis hole B by through hole, the inwall of described through hole is provided with screw thread, step is provided with in described axis hole B, axis hole B is divided into hole A and hole B by described step, the diameter of described hole A is less than hole B, the bolt that one end penetrates axis hole A is provided with in described axis hole A, the other end of described bolt is provided with outer six square toes.
Wherein, the diameter of described through hole is less than the diameter of axis hole A and the diameter of hole A.
Owing to have employed technique scheme, the utility model has structure advantage simple, easy to operate, with low cost, adopt it to carry out fast connecting and dismantling, prevent in unloading process, damage the generation of phenomenon, simultaneously, owing to having hole A, when dismantling, there is buffer area, dismantling more laborsaving, reduce labor intensity, improve working efficiency.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of screwed coupling, comprise cylindrical body, the outer wall of described body 1 is provided with and connects tooth 2, axis hole A3 and axis hole B is respectively arranged with in the two ends of described body 1, described axis hole A3 is communicated with axis hole B by through hole 4, the inwall of described through hole 4 is provided with screw thread 5, step 6 is provided with in described axis hole B, axis hole B is divided into hole A7 and hole B8 by described step 6, the diameter of described hole A7 is less than hole B8, the bolt 9 that one end penetrates axis hole A3 is provided with in described axis hole A3, the other end of described bolt 9 is provided with outer six square toes 10.
Further describe, the diameter of described through hole 4 is less than the diameter of axis hole A3 and the diameter of hole A7.
The main shaft of motor in use, penetrates in axis hole B by the utility model, and the screw thread on engine spindle is connected with the screw thread 5 in through hole 4.Connection tooth 2 of the present invention engages with the tooth on test bench and body can be driven to rotate.
