Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Please refer to fig. 1, the embodiment provides an oilless air compressor pump shaft cover clamping device convenient to prevent dislocation, including two articulated supporting rods 1 together, supporting rod 1 includes splint 2 and handle 3, the inner wall of splint 2 is connected with laminating board 5 that can increase static friction between splint 2 and shaft cover outer wall through reset spring 4, reset spring 4 can keep laminating with the outer wall of shaft cover laminating board 5, through increasing the frictional force between laminating board 5 and the shaft cover outer wall, can prevent effectively that the shaft cover from carrying out the condition that the pressfitting operation in-process appears removing, and then can prevent the shaft cover dislocation.

Wherein, splint 2 are the arc structure, and preferred splint 2 is the oval type structure of half, through the laminating of 2 inner wall two points of splint and axle cap outer wall, can increase the pressure at two points of splint 2 and axle cap outer wall laminating to through the common centre gripping of two splint 2 to the axle cap, can further promote the effect of holding with adding of axle cap.

In order to prevent that laminating board 5 from appearing the piece breakage with the laminating department of axle cap outer wall, reset spring 4 is provided with a plurality ofly, and a plurality of reset spring 4 arrange at the inner wall equidistance of splint 2, and a plurality of reset spring 4 are through the extension of self, make laminating board 5 can form a curved surface of laminating with axle cap outer wall department, and then can prevent that the great condition of camber from appearing in certain department of laminating board 5, effectively prevent laminating board 5's breakage.

In order to prevent that laminating board 5 and reset spring 4's junction from appearing the damage, be provided with between reset spring 4's tip and the laminating board 5 and prevent laminating board 5 damaged bearing plate 6, bearing plate 6 includes a plurality of movable block 61, it is articulated between the adjacent movable block 61, the side that movable block 61 kept away from mutually is fixed with reset spring 4's tip and laminating board 5's side respectively, can realize keeping apart between reset spring 4 and laminating board 5 through bearing plate 6, direct contact between reset spring 4 and the laminating board 5 has been avoided.
