Abstract
A fastening bolt comprises a screw and a nut. The screw comprises a head part and a rod part. The rod part is fixed in the center of the head part, springs are arranged on the head part around the rod part, cylindrical plastic rods are arranged in the centers of the springs, and the bottoms of the plastic rods and the head part are fixed. The number of the springs is at least three, and the springs are evenly distributed on the head part around the rod part. A plastic ring is arranged on the surface, which is in threaded connection and faces toward the head part, of one side of the nut, the plastic ring and a threaded hole in the center of the nut are concentric circles, and the plastic ring is arranged on the surface of the nut in a more-than-two-circle mode. The structure is simple, using is convenient, force of the thread contact surface in a connecting state is increased, stability of connecting is improved, and loosening is effectively prevented.
Description
Technical field
The utility model relates to clamping bolt, and it is a kind of bolt that enhancing annexation stability can be arranged, and belongs to fastener areas.
Background technique
Bolt is a kind of fastening piece of commonly using, it relies on nut thread to be connected to bar section, realization connects two articles, many times, after bolt is connected on object, be exactly to be fixed on muchly on object, bolted steadiness is very important, if loosening, can make the object operation irregularity, cause very serious consequence.Traditional bolt in use, head directly contacts with object with nut, because bolt is long, be metal properties, vibrations in use or friction, can make the contact surface wearing and tearing, power on final screw thread surface of contact reduces, and connects and becomes flexible, and the final object that connects can not fixedly link together.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of clamping bolt, when this clamping bolt connected two articles, the contact joint was more fastening, is not easy to be quaked loose.
Clamping bolt, comprise screw and nut, and described screw comprises head and bar section, and bar section is fixed on the center of head, on the head of bar section surrounding, is provided with spring, and the center of spring is provided with the plastic cement rod of cylindrical shape, and bottom and the head of plastic cement rod are fixed.
Described spring has 3 at least, is evenly distributed on the head of bar section surrounding.
Described nut thread connects a headward side surface and is provided with plastic tube, and the tapped hole at plastic tube and nut center is concentric circle, and plastic tube is more than there are two circles on the nut surface.
The utility model, simple in structure, easy to use, during use, the attachment hole of fastening is run through in bar section, and head is attached to the fastening surface, in the process that nut and bar section screw thread screw, head maintains static all the time, and nut is screwed to fastening, spring will be pressed to such an extent that press close to head, also tightr with the fastening laminating, final plastic cement rod is also fitted with fastening, strengthens the stability of annexation, simultaneously, the plastic tube on nut surface also has the effect that strengthens connective stability.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 be the A of Fig. 1 to view,
Fig. 3 be the B of Fig. 2 to view,
Reference numerals list: 1-head, 2-bar section, 3-nut, 4-screw, 5-plastic cement rod, 6-spring, 7-plastic tube.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand following embodiment and only be used to the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometrical center.
Visible by reference to the accompanying drawings, this clamping bolt, comprise screw 4 and nut 3, described screw 4 comprises head 1 and bar section 2, bar section 2 is fixed on the center of head 1, on the head 1 of bar section 2 surroundings, be provided with spring 6, the center of spring 6 is provided with the plastic cement rod 5 of cylindrical shape, and the bottom of plastic cement rod 5 and head 1 are fixing.The utility model, bar section 2 is used for being applied in the attachment hole of fastening, and head 1 is fixing with bar section 2, head 1 is in the outside of fastening, and nut 3 is tightened in the other end of bar section 2, and is final, fastening is fixed on bar section 2, head 1 and nut 3 are fixed fastening from two ends, and 6 pairs of fastenings of spring have the conflict effect, and 5 pairs of fastenings of plastic cement rod have the thrust of buffering, after nut 3 is tightened, on surface of contact between screw thread, bear and put forth effort all the time, can maintain static holding position, annexation is more stable.
Described spring 6 has 3 at least, is evenly distributed on the head 1 of bar section 2 surroundings, and being uniformly distributed of spring 6 can guarantee that head 1 is stressed evenly.
The described nut 3 headward side surface that is threaded is provided with plastic tube 7, and plastic tube 7 is concentric circle with the tapped hole at nut 3 centers, and plastic tube 7 is more than there are two circles on nut 3 surfaces.Plastic tube 7 can strengthen the stable relation of nut 3 and fastening, drops after avoiding nut 3 loosening.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technological scheme that is comprised of above technical characteristics combination in any.
