Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.
As illustrated in fig. 1 and 2, the utility model is a kind of elbow expansion bolt dismounting new tool, comprise sleeve 10 and be installed on fixed screw 20 and the fork 30 on sleeve 10, described sleeve 10 inside offer the curved hole 11 matching with expansion bolt elbow part along its axis direction, on the sidewall of described sleeve 10, offer with curved hole 11 and be screw hole arranged in a crossed manner 12 and through hole 13, described fixed screw 20 is installed in screw hole 12, and described fork 30 is inserted in described through hole 13.The utility model elbow expansion bolt dismounting new tool, the elbow portion of elbow expansion bolt can be inserted in curved hole 11, because curved hole 11 has hole shape and the aperture of mating with the elbow portion of bolt, therefore sleeve 10 can keep one with bolt with one end bent back, simultaneously by with the screw hole 12 of curved hole 11 cross-shaped states in fixed screw 20 carry out further fastening to bolt elbow portion, make together with sleeve 10 more firmly fixes with elbow expansion bolt, in addition, on sleeve 10, be also provided with the fork 30 arranged in a crossed manner with curved hole 11, in the time that needs knock in body of wall by bolt, can directly knock sleeve 10 bottom surfaces, can be by percussion power balance Transmit evenly to elbow expansion bolt, and in the time need to adjusting the orientation of elbow expansion bolt or need to extract bolt, can rotate or stir fork 30, can bolt be adjusted or be extracted, and the dynamics of adjusting or extracting is after the leverage of fork 30 regulates, more convenient laborsaving.Therefore, frock of the present utility model, in the time that elbow expansion bolt is carried out to multiple operation, possesses and makes bolt strained balance even, is very easy to the advantage of the fitting operation of bolt.
In order further to improve the fastening fixing of sleeve 10 to elbow expansion bolt, improve the stressing conditions of elbow expansion bolt in the time of operation, and the openend axis in described curved hole 11 is vertical with the bottom surface of sleeve 10, when the elbow portion of elbow expansion bolt insert curved hole 11 interior after, elbow portion can all be held by curved hole 11 simultaneously, therefore the straight-bar portion of elbow expansion bolt is positioned at sleeve 10 outsides, because of the openend axis in described curved hole 11 vertical with the bottom surface of sleeve 10, the bottom surface of straight-bar portion and sleeve 10 is also vertical configuration like this, in the time knocking sleeve 10, dynamics can straight-line transmitting be handed to the straight-bar portion of elbow expansion bolt and the axis transmission along straight-bar portion, make percussion power further reach balance and uniform state, reach both laborsaving, operation effect easily again.In the time that needs rotate or extract elbow expansion bolt, can operate fork 30, make to form leverage between fork 30 and sleeve 10, sleeve 10 forms leverage with the elbow portion of elbow expansion bolt, after the addition effect of secondary Labor-saving, rotate or extract operation and will become very laborsaving.
For make the elbow portion of elbow expansion bolt fastened be fixed in sleeve 10, the crossover sites of described curved hole 11 and screw hole 12 is perpendicular to described screw hole 12, after fixed screw 20 and screw hole 12 enter by threaded engagement, the head of fixed screw 20 will withstand on the curved head side wall of elbow expansion bolt, the now contact position with elbow expansion bolt at fixed screw 20, the elbow portion of fixed screw 20 and elbow expansion bolt is in plumbness, make the head of fixed screw 20 and the contact area of elbow expansion bolt reach maximization, allow the frictional force between the two reach maximum simultaneously, can make elbow expansion bolt be more securely fixed in sleeve 10.
Under some special installation environments, a curved hole 11 towards the restriction that may and be not suitable for installing space, therefore described curved hole 11 comprises composition 14Yu You hole, lambdoid left hole 15, and 14Yu You hole, described left hole 15 is symmetrical arranged with the axis of described sleeve 10, make the towards the opposite of 14Yu You hole, left hole 15, so curved hole 11 just have two relative towards, can meet better the restriction of installing space, improve the adaptability of the utility model to environment for use.
In addition, in order further to improve the fastening fixing of sleeve 10 to elbow expansion bolt, described screw hole 12 at least has two, and lay respectively at opposite side or the same side of described sleeve 10, even all right, at the axis direction along described sleeve 10, described screw hole 12 has at least two to be positioned at different height and positions.At sleeve 10 axis and/or diverse location in the radial direction, each direction hole 12 of tightening up a screw distributes at least two, by this mode that increases in place screw hole 12, when all installing after fixed screw 20 in whole screw holes 12, the fastening force of elbow expansion bolt will be reached to higher degree, effectively ensure the fastening fixing of sleeve 10 to elbow expansion bolt.In order to facilitate the operation that is screwed to of fixed screw 20, can the ear 21 conveniently turning be set at described fixed screw 20.
Be unlikely to automatically to deviate from after interior in order to make fork 30 be installed to through hole 13, described fork 30 two ends have round cap 31, the diameter of described round cap 31 is greater than the diameter of described through hole 13, although fork 30 can slide axially in through hole 13 like this, but can not in through hole 13, exit, fork 30 also can be arbitrarily to a side slip of sleeve 10 to maximum length, carry out turnbarrel 10 with this.For make rotation or extract etc. operates more laborsaving, described through hole 13 is positioned at the position near the bending section in described curved hole 11, preferably the length of described fork 30 is not less than 3 times of described sleeve 10 bottom surface Breadth Maximums, and while making to operate on fork 30, moment is larger, therefore can be more laborsaving.
