Abstract
The invention discloses a bolt which comprises a screw rod, a nut, a push rod and a stop block; a guide hole coaxial with the screw rod is formed in the center of the screw rod; the push rod is arranged in the guide hole in a threaded connection manner, and the top end of the push rod, which is inserted in the guide hole, is tapered; a through groove is formed in the circumference of the screw rod in the direction perpendicular to the center line of the guide hole; and the stop block is positioned in the through groove and can side in the through groove. The bolt adopting the scheme and provided by the invention is applicable to fastening of various workpieces in sandwich space, and is very simple in operation; and only a hole with the diameter same as that of the screw rod is required to be drilled, so that the application range of the bolt is expanded, and the fastening strength of the workpieces is improved.
Description
Technical field
The present invention relates to a kind of fastening piece, especially a kind of bolt belongs to the fastenings technical field.
Background technique
Bolt all is made up of screw rod and nut, when fixation workpiece, all is that screw rod is passed workpiece, carries out fastening through nut then.But, for some workpiece that can not overturn or in mezzanine space, it can only connect fastening in the front of workpiece, and existing bolt just can not use.For this reason, Chinese patent number is ZL 200920174809.0, and name is called the utility model patent of " skewed slot bolt "; Disclose a kind of skewed slot bolt, bolt shank is provided with skewed slot, places a baffle plate in the skewed slot; Through on workpiece, boring a hole in advance greater than the bolt shank diameter; After passing screw rod and baffle plate in the hole simultaneously, the pulling screw rod makes baffle plate erect, and workpiece is fixed.Though this skewed slot bolt can solve the fastening problem of mezzanine space workpiece, the installation and removal of bolt are all very inconvenient, and when spurring bolt shank back and forth, baffle plate is easy to and bolt shank breaks away from, can not second use; And for the narrow workpiece of some mezzanine spaces, when fastening, baffle plate can not pass completely through workpiece, just can not use; In addition, also need on workpiece, get out a hole bigger than bolt shank diameter in advance, it is very inconvenient to operate.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: a kind of workpiece that is applicable to fixing various mezzanine spaces has been proposed, and bolt easy and simple to handle.
Technical solution of the present invention is achieved in that a kind of bolt, comprises screw rod, nut, push rod and block; The center of said screw rod has the pilot hole with screw coaxial; Said push rod is located in the pilot hole through being threaded, and the top that push rod inserts in the pilot hole is taper; On the circumference of said screw rod, on the direction perpendicular to the pilot hole center line, have groove; Said block is positioned at groove, and block can slide in groove.
Preferably, said block bottom surface is the inclined-plane, and the gradient of block bottom surface is identical with the conical surface of push rod.
Preferably, said groove is two, and symmetrical with respect to the axis of screw rod.
Preferably, the said push rod end that stretches out screw rod is fixed with rotating block.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Bolt of the present invention, it utilizes the push rod in the screw rod, the slip of control groove internal stop; The block through being positioned at interior and the nut of outer workpiece; The workpiece of mezzanine space is carried out fastening, operation is very simple, and only need bore the hole identical with screw diameter and get final product; Enlarge the Applicable scope of bolt, improved the fastening strength of workpiece.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing l is a bolt of the present invention plan view when using;
Accompanying drawing 2 is a bolt of the present invention sectional view when using;
Wherein: 1, workpiece; 2, nut; 3, screw rod; 4, pilot hole; 5, push rod; 6, groove; 7, block; 8, rotating block.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2 is a kind of bolt of the present invention, comprises screw rod 3, nut 2, push rod 5 and block 7; The center of said screw rod 3 has the pilot hole 4 coaxial with screw rod 3; Said push rod 5 is located in the pilot hole 4 through being threaded, and the top that push rod 5 inserts in the pilot hole 4 is taper; On the circumference of said screw rod 3, on the direction perpendicular to pilot hole 4 center lines, have groove 6; Said groove 6 is two, and symmetrical with respect to the axis of screw rod 3; Said block 7 is two, and all is positioned at groove 6; Said block 7 all can slide in groove 6; The bottom surface of said block 7 is the inclined-plane, and the gradient of block 7 bottom surfaces is identical with the conical surface of push rod 5; The end that said push rod 5 stretches out screw rod 3 is fixed with rotating block 8.
During use, rotate rotating block 8 earlier, push rod 5 to pilot hole 4 inner rotary, is made that the slide block 7 in the groove 6 slides to pilot hole 4 directions; After in groove 6 is slipped on the top of slide block 7, screw rod 3 is inserted in the workpiece 1; The counter-rotation rotating block 8 again; Push rod 5 is rotated in pilot hole 4, because the acting in conjunction of the inclined end face of conical surface on the push rod 5 and block 7 makes the top of block 7 slide to the outside of groove 6 gradually; Block 7 top tight workpieces 1; At last, screw rod 3 is fixed, can be realized the fastening of workpiece 1 with nut 2.Easy to operate, come fastening workpiece through block and nut acting in conjunction, fastening strength is very high; And do not need redrilling, and improved working efficiency greatly, also enlarged the Applicable scope of bolt.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
