Abstract
The utility model relates to a kind of fixing device of sleeve pipe, comprise rotating shaft (1), slip joint casing (2) in rotating shaft, the side of sleeve pipe is provided with sleeve (2a), it is characterized in that: the inner side surface of sleeve is provided with one group of groove (2b), and be connected a jacking block (3) in each groove, the barrel of sleeve is also provided with one group of screw (2c), screw and groove one_to_one corresponding, be connected locking element (4) in screw, and sleeve pipe is locked with rotating shaft by locking element and jacking block and coordinated.Advantage of the present utility model: this apparatus structure is simple, easily manufactured, becomes not low and easily processes, the locking of this device to sleeve pipe and rotating shaft is firm, and countershaft surface nondestructive wound.
Description
Technical field
The utility model relates to a kind of mechanical fastening system, particularly a kind of fixing device of sleeve pipe.
Background technique
The mechanical field of present stage is special, when sleeve pipe and rotating shaft fixing, most employing is provided with screw on sleeve pipe, then by screw, bolt or stud are directly locked with rotating shaft and are coordinated, and this mode is when working long hours, easily loosen, and when fastening screw, the surface of bolt or the easy countershaft of stud forms damage, and the surface of rotating shaft generally can be made to occur pit or scratch.Through extensively retrieval, not yet find ideal technological scheme.
Model utility content
The purpose of this utility model is to solve the fixing insecure of present stage rotating shaft and sleeve pipe, and rotating shaft surface easily occurs the shortcomings such as damage, and the fixing device of a kind of sleeve pipe of proposition.
To achieve these goals, the utility model have employed following technological scheme:
A kind of fixing device of sleeve pipe, comprise rotating shaft, slip joint casing in rotating shaft, the side of sleeve pipe is provided with sleeve, it is characterized in that: the inner side surface of described sleeve is provided with one group of groove, and be connected a jacking block in each groove, the barrel of sleeve is also provided with one group of screw, screw and groove one_to_one corresponding, to be connected locking element at screw, locked coordinate in sleeve pipe by locking element and jacking block with rotating shaft.
On the basis of technique scheme, following further technological scheme can be had:
The bottom surface of described groove is the circular arc concentric with sleeve, and wherein two symmetrical sides of described jacking block are respectively the circular arc corresponding with the bottom surface of groove and rotating shaft.
Described locking element adopts screw, bolt or stud.
When described locking element is tightened, locking element compresses jacking block, jacking block clamping shaft, and because the surface of jacking block and shaft contacts is arc structure, and surface of contact is larger, so locking is comparatively firm, and countershaft not damaged.
The utility model has the advantage of: this apparatus structure is simple, easily manufactured, becomes not low and easily processes, the locking of this device to sleeve pipe and rotating shaft is firm, and countershaft surface nondestructive wound.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the fixing device of a kind of sleeve pipe that the utility model provides, comprises rotating shaft 1, slip joint casing 2 in rotating shaft 1, and the side of sleeve pipe 2 is provided with sleeve 2a, it is characterized in that:
The inner side surface of a, described sleeve 2a is provided with four groove 2b, the length of groove 2b is less than the width of sleeve pipe, the bottom surface of described groove 2b is the circular arc concentric with sleeve 2a, and two sides of groove 2b are perpendicular with the tangent line of the circular arc at its bottom surface and opening place respectively.
B, be connected a jacking block 3 in each groove, upper and lower two symmetrical sides of described jacking block 3 are respectively the circular arc corresponding with the bottom surface of groove 2b and rotating shaft 1, and during cooperation, the tangent line of the circular arc at the place, two sides of two sides of jacking block 3 and the upper and lower of jacking block 3 is perpendicular.
C, on the barrel of sleeve 2a, be also provided with one group of screw 2c, screw 2c and groove 2b one_to_one corresponding, to be connected locking element 4 at screw 2c, locking element 4 is bolt, is locked coordinate in sleeve pipe 2 by locking element 4 and jacking block 3 with rotating shaft 1.
