Abstract
The invention relates to a reinforced break-up bolt which comprises a screw (1), a bolt sleeve (2), a gasket (3), a spring piece (4) and a fastening nut (5). One end of the screw (1) is a threaded end (7), the other end of the screw (1) is a cone frustum end (6), a spherical surface (8) is formed at the front end of the cone frustum end (6), the bolt sleeve (2) is sleeved on the screw (1), the fastening nut (5) is arranged at the threaded end (7) of the screw (1), and a gasket (3) and the spring piece (4) are arranged between the fastening nut (5) and the bolt sleeve (2). The reinforced break-up bolt is simple in structure, reasonable in design, low in manufacturing cost, high in strength, tight and firm in connection, safe and reliable, and working intensity is relieved.
Description
Technical field
The present invention relates to technical field of fastening, relate in particular to a kind of reinforced explosion bolt that draws.
Background technique
Draw explosion bolt to be used for being connected of object and body of wall, only need become flexible during the object dismounting draws explosion bolt to get final product, the general explosion bolt that draws is made up of screw rod, swivel nut and tightening nut, simultaneously for drawing explosion bolt that high strength is arranged and being connected requirement closely, because bolt strength not higher position can't be squeezed into body of wall, may before squeezing into body of wall, rupture, and must guarantee simultaneously to connect closely, just might bring safety problem if become flexible, much draw explosion bolt to squeeze into difficulty of body of wall in addition, workman's physical output is big.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of reinforced explosion bolt that draws is provided, the intensity height connects close and firm, and is safe and reliable, alleviated working strength.
The present invention is achieved through the following technical solutions: a kind of novel explosion bolt that draws, comprise screw rod, bolt sleeve, pad, spring sheet, tightening nut, described screw rod one end is threaded end, the other end is the round platform end, described round platform end front end is sphere, be with bolt sleeve on the described screw rod, described screw flight end is arranged tightening nut, positioned spacers and spring sheet between described tightening nut and the bolt sleeve.
Further, described bolt sleeve one end withstands the round platform end, and the other end contacts with pad.
Further, described bolt sleeve is arranged several U-shaped flutings near the round platform end, arranges several circular holes by the middle part.
Further, described tightening nut is furnished with 2.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is simple in structure, and is reasonable in design, low cost of manufacture, at the screw rod end two nuts are set, add spring sheet simultaneously, the intensity height, screw front end is designed to truncated conical shape, and at the round platform front end sphere is set, guarantee to connect close and firm, safe and reliable, also alleviated working strength.
Description of drawings
Fig. 1 is a kind of novel plan view that draws explosion bolt of the present invention;
Fig. 2 is the plan view of screw rod of the present invention.
Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Shown in Fig. 1-2, the present invention relates to a kind of novel explosion bolt that draws, comprise screw rod 1, bolt sleeve 2, pad 3, spring sheet 4, tightening nut 5, described screw rod 1 one ends are threaded end 7, the other end is round platform end 6, described round platform end 6 front ends are sphere 8, be with bolt sleeve 2 on the described screw rod 1, the threaded end 7 of described screw rod 1 is arranged tightening nut 5, positioned spacers 3 and spring sheet 4 between described tightening nut 5 and the bolt sleeve 2, and described bolt sleeve 2 one ends withstand round platform end 6, the other end contacts with pad 3, described bolt sleeve 2 is arranged several U-shaped flutings 9 near round platform end 6, arranges several circular holes 10 by the middle part, and described tightening nut 5 is furnished with 2.
In sum, the present invention is simple in structure, and is reasonable in design, low cost of manufacture, by the threaded end 7 at screw rod 1 two tightening nuts 5 are set, add the mode of spring sheet 4 simultaneously, make bolt possess higher intensity, the Front-end Design of screw rod 1 is become truncated conical shape, and the Front-end Design at round platform end 6 becomes sphere 8, guarantee to connect close and firm, safe and reliable, also alleviated working strength.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
