Abstract
An anti-disassembly nut comprises a nut body, wherein, an opening is arranged at the tail end of the nut body, and an elastic part is arranged in the depression part of the tail end of a thread at the internal surface of the nut body. The elastic part is a tension spring which is formed by a triangular metal wire, the inner diameter of the tension spring is slightly smaller than the outer diameter of a screw rod, the outer diameter of the tail end of the tension spring is slightly smaller than the inner diameter of the tail end of the nut body, the tension spring can form a grip force to the screw rod after being screwed in the depression of the nut, when the nut is screwed back, the nut, the spring and the screw rod can generate the force to prevent the screwing back of the nut at the tail end of the spring, the force is opposite to the direction of the disassembly force, the greater the disassembly force, the greater the force for preventing the disassembly force is, thus preventing the disassembly of the nut. The anti-disassembly nut is mainly used for the connection in tower materials of a power transmission tower, the connection and the installation of a highway barrier and a protection net and the connection of the parts without the need of disassembly.
Description
Technical field
The utility model relates to a kind of nut, specifically, relates to a kind of tamper nut of dismantling of not allowing.
Background technique
The fixed combination nut of communal facility, and some component need disposable connection, and do not allow the parts dismantled.The structure that comprises open-air shaft tower, it is solid to adopt plain nut to connect.Between the non-operational period of construction, artificially backed out easily with general tool, steal facility, equipment, goods and materials etc. cause damage.
For addressing this problem, way has usually: the fastening back spot welding of nut; It is moulding to change lead screw with external force; Even connect with taking out heart aluminum rivet, but intensity is restricted.Also the useful metal rivet clasp makes it and can not be unscrewed.But aforesaid operations can bring difficulty to work, and especially the high-altitude difficulty of construction is big.
The model utility content
The problem that the utility model solved provides a kind of anti-dismounting nut of practicality.
In order to address the above problem, the utility model provides a kind of tamper nut, comprise the nut body, the internal surface of nut body is provided with screw thread, rear end at the internal surface of nut body is provided with opening, internal surface threaded recess place at the nut body is provided with elastic member, and the front end of elastic member is arranged at the end of nut screw thread.
Described elastic member is extension spring;
The internal diameter of described extension spring is less than screw rod external diameter 0.3～0.7mm, and the external diameter of extension spring is less than the internal diameter 0.3～0.7mm of nut body;
The front end of described extension spring is less than rear end 0.3～0.7mm;
The Manufacturing material of described extension spring is a wire triangular in shape;
Described opening is the horn shape that progressively enlarges;
Described extension spring length is less than the length 0.3～1.0mm of opening.
The utility model only is mainly used in and need once be fastenedly connected, and do not allow the place of dismantling, its principle is provided with the extension spring with elastic force for the threaded recess place at nut, the external diameter of extension spring is slightly less than the internal diameter of nut body, the extension spring internal diameter is slightly less than the external diameter of screw rod, for extension spring is combined with screw thread better, extension spring is made by wire triangular in shape, be provided with the front end of extension spring less, the rear end is provided with bigger, the front end that is extension spring combines with nut internal surface screw thread termination, and extension spring promptly can be embedded in the threaded recess of nut like this, simultaneously after extension spring screws screw rod, the extension spring meeting produces the grip to screw rod, and the opening of nut end is blocked, made nut not to be disassembled, if smear fastening colloid effect in spring and screw rod junction better.The utility model only is mainly used in needs once fastening connection, and does not allow the place of dismantling, as the connection between the tower material in the electric power transmission iron tower; Expressway protects and blocks and the connection of protective net;
The utility model will be further described below in conjunction with description of drawings and embodiment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view
Fig. 3 is the structural representation of a kind of extension spring among the utility model embodiment.
Fig. 4 is the utility model-embodiment's a structural representation.
Embodiment
Referring to figs. 1 through Fig. 4, the tamper nut of present embodiment comprises nut body 1, internal surface at nut body 1 is provided with screw thread, be provided with two openings 2 in the rear end of nut body 1, internal surface threaded recess 3 places at nut body 1 are provided with elastic member 4, and the front end 6 of elastic member 4 is arranged on the rear end of threaded recess 3.Described elastic member 4 is extension spring, and the internal diameter of extension spring is less than screw rod 7 external diameter 0.5mm, and the extension spring external diameter is less than the internal diameter 0.5mm of nut body 1; The external diameter of the front end 6 of described extension spring is less than the external diameter 0.5mm of rear end, and the Manufacturing material of extension spring is a wire triangular in shape; Described opening 2 is the horn shape that enlarges gradually, and extension spring length is less than the length 0.5mm of opening 2.
After extension spring screws screw rod 7, because the internal diameter of extension spring is slightly less than the external diameter of screw rod 7, the front end 6 of extension spring fastens screw rod 7, and screw rod is produced certain grip, when dismounting person wanted to screw out nut body 1, extension spring can increase with the increase of removal force the grip of screw rod 7; Meanwhile,, make to produce a stress between threaded recess 3 and the extension spring, stop nut to be screwed out, prevent that nut body 1 from being screwed out screw rod 7 thereby reach along with nut body 1 screws out outward; Because the length of extension spring less than the length of opening 2, makes dismounting person's extension spring of thinking to dismantle earlier also become impossiblely, this has just prevented that nut from being dismantled fully.
Referring to figs. 1 through Fig. 4, present embodiment is that with the difference of implementing 1 the extension spring internal diameter is less than the external diameter 0.3mm of screw rod 7, and the extension spring external diameter is less than the internal diameter 0.7mm of screw rod body 1, and extension spring length is less than opening length 0.3mm.
Referring to figs. 1 through Fig. 4, present embodiment and embodiment's 1 difference is, the extension spring internal diameter is less than the external diameter 0.7mm of screw rod 7,, the extension spring external diameter is less than the internal diameter 0.3mm of screw rod body 1, and extension spring length is less than opening length 1.0mm.
Installation process of the present utility model is; Earlier nut body 1 is tightened in the screw rod 7, select suitable extension spring according to the size and the hand of spiral of screw rod 7 then, re-using special tool screws in extension spring in the threaded recess 3 of nut internal surface from opening 2, extension spring simultaneously also will screw screw rod 7, smear fastening colloid in extension spring and screw rod 7 junctions at last, installation process is promptly finished.
