Abstract
The utility model discloses a wedge-shaped fastening nail. The wedge-shaped fastening nail comprises a nail body, wherein the lower end of the nail body retracts to the center of the nail body so as to form a sharp end; a fastening chamber sucken downwards is formed in the upper end surface of the nail body; an ejector rod, of which the length is consistent with the depth of the fastening chamber, is arranged in the fastening chamber; the bottom end of the ejector rod is wedge-shaped; at least two through holes communicated with the fastening chamber are formed in the side wall of the nail body; the through holes of the nail body have different heights; movable blocks are arranged in the through holes; one ends of the movable blocks are aligned with the surface of the nail body; the other ends of the movable blocks are fixedly connected with ejecting blocks with right triangle-shaped longitudinal sections; the inclined edges of the ejecting blocks are upwards; and one ends of the ejecting blocks, which are far away from the movable blocks, are propped against the side wall of the fastening chamber opposite to the through holes. The wedge-shaped fastening nail disclosed by the utility model has the advantages as follows: as a technical scheme is adopted, the movable blocks can be ejected into a gap between the nail body and a target object after the nail body is nailed into the target object, so that the nail body is prevented from being loosened and separated.
Description
Technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of wedge shape clench nail.
Background technique
Iron nail is very common a kind of in the present fastening piece, and it is to be made of ailhead and nail bar, and the front end of nail bar shrinks to its center and forms sharp-pointed section, can hammer into swimmingly in the target piece by this sharp-pointed section, plays good fastening effect.But, this traditional iron nail that always uses, the nail bar is round and smooth, does not have anti-skid structure, causes easily getting loose between itself and the target piece, and can become flexible gradually, deviate under along with vibrations or other External Force Acting, makes troubles to people.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of wedge shape clench nail is provided, and it can be avoided iron nail to become flexible in target piece or deviate from.
The technological scheme that the utility model adopts is: a kind of wedge shape clench nail, comprise rivet nut, described rivet nut lower end is shunk to its center and is formed a sharp end, the upper-end surface of described rivet nut is provided with a fastening chamber to lower recess, be provided with the length push rod consistent with the fastening chamber degree of depth in the described fastening chamber, the bottom of described push rod is wedge shape, the sidewall of described rivet nut is provided with at least two through holes that communicate with described fastening chamber, the height of through hole is not identical on the described rivet nut, be provided with movable block in the described through hole, one end of described movable block and described rivet nut flush, its the other end is fixedly connected with the rectangular leg-of-mutton jacking block of a longitudinal profile, the hypotenuse of described jacking block is towards the top, and jacking block is tight against on the sidewall of the fastening chamber on through hole opposite away from an end of movable block.
As preferably, be provided with altogether two through holes on the described rivet nut, their direction and highly all not waiting.
The beneficial effects of the utility model are: because the utility model adopts technique scheme, after rivet nut is hammered into target piece, can movable block be headed between the gap of rivet nut and target piece by push rod, thereby prevent becoming flexible and deviating from of rivet nut; And the jacking block of movable block by right-angled triangle contact with push rod, so that the amount of exercise of movable block increases to the diameter in fastening chamber, makes rivet nut more firm.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, rivet nut; 2, sharp end; 3, fastening chamber; 4, push rod; 5, through hole; 6, movable block; 7, jacking block.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of wedge shape clench nail, comprise rivet nut 1, described rivet nut 1 lower end is shunk to its center and is formed a sharp end 2, the upper-end surface of described rivet nut 1 is provided with a fastening chamber 3 to lower recess, be provided with the length push rod 4 consistent with fastening chamber 3 degree of depth in the described fastening chamber 3, the bottom of described push rod 4 is wedge shape, the sidewall of described rivet nut 1 is provided with at least two through holes 5 that communicate with described fastening chamber 3, be provided with altogether two through holes 5 on the described rivet nut 1, their direction and highly all not waiting, be provided with movable block 6 in the described through hole 5, an end of described movable block 6 and described rivet nut 1 flush, its other end is fixedly connected with the rectangular leg-of-mutton jacking block 7 of a longitudinal profile, the hypotenuse of described jacking block 7 is towards the top, and jacking block 7 is tight against on 3 sidewalls of the fastening chamber on through hole 5 opposites away from an end of movable block 6.
Because the utility model adopts technique scheme, after rivet nut 1 is hammered into target piece, can movable block 6 be headed between the gap of rivet nut 1 and target piece by push rod 4, thereby prevent becoming flexible and deviating from of rivet nut 1; And the jacking block 7 of movable block 6 by right-angled triangle contact with push rod 4, so that the amount of exercise of movable block 6 increases to the diameter in fastening chamber 3, makes rivet nut 1 more firm.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
