The specific embodiment
In order to make object of the present invention, principle 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 explain the present invention, is not intended to limit the present invention.
As shown in Figure 1 to 4, a kind of nut fixing device that the embodiment of the present invention provides, be located in nut fixing hole 4, this nut fixing device comprises the substrate 1 that is bent into certain angle, substrate 1 is located on nut 2, center offers and can hold the through hole 11 that bolt 3 passes, and edge is provided with outward extending sawtooth 12.In order to make substrate 1 can put into nut fixing hole 4, the appearance and size of substrate 1 is less than the size of nut fixing hole 4; For substrate 1 can be fixed on nut 2 in nut fixing hole 4, appearance and size after substrate 1 flattens is greater than the size of nut fixing hole 4, the sawtooth 12 at substrate 1 edge can snap in the hole wall of nut fixing hole 4 like this, plays nut 2 is fixed on to the effect in nut fixing hole 4.
During use, first nut 2 is located in nut fixing hole 4, then nut 2 and bolt 3 are screwed together, then substrate 1 is placed on nut 2, allows the through hole 11 of bolt 3 passing through substrates 1 simultaneously, because the appearance and size of substrate 1 is less than the size of nut fixing hole 4, therefore substrate 1 directly can be put into nut fixing hole 4, next, substrate 1 is applied to the external force perpendicular to it, make substrate 1 stress deformation, the stressed flattening of substrate 1 (as shown in Figure 2), because substrate 1 appearance and size after flattening is greater than the size of nut fixing hole 4, therefore the hole wall of 1 pair of nut fixing hole 4 of substrate forms extruding force, the edge of adding substrate 1 is provided with outward extending sawtooth 12, so sawtooth 12 can tightly snap in the hole wall of nut fixing hole 4, make substrate 1 firmly fixing in nut fixing hole 4, thereby nut 2 is fixed in nut fixing hole 4 firmly, neither can allow nut 2 not drop when having bolt 3 to screw, can not allow yet nut 2 after being spirally connected with bolt 3 because vibrations etc. are former thereby come off from bolt 3.
Below each part of the embodiment of the present invention is described in detail.
As depicted in figs. 1 and 2, in the present embodiment, the crooked place of substrate 1 is positioned at one symmetry axis place, and the bending angle of substrate 1 is 120～170 °, so that substrate 1 easily flattens when substrate 1 is exerted pressure.
The substrate 1 of the present embodiment is specially hexagon, because the cross section of nut fixing hole 4 is hexagon, so substrate 1 adopts hexagonal structure to be convenient to mate with nut fixing hole 4, substrate 1 can be fixed on nut 2 in nut fixing hole 4 better.
As shown in Figure 1, sawtooth 12 is positioned on relative its symmetrical axisymmetric two limits of substrate 1.Wherein, sawtooth 12 parts are bent upwards, a part is bent downwardly, and the sawtooth 12 and the reclinate sawtooth 12 that are bent upwards are staggered successively.When substrate 1 is after the interior flattening of nut fixing hole 4, sawtooth 12 tightly snaps in the hole wall of nut fixing hole 4, makes substrate 1 firmly fixing in nut fixing hole 4, thereby plays the effect of hold-down nut 2; Meanwhile, because sawtooth 12 parts are bent upwards, a part is bent downwardly, so sawtooth 12 can also prevent that substrate 1 fluctuates up or down, further guarantees that substrate 1 is fixed on nut 2 in nut fixing hole 4 firmly.
In addition, on all the other limits of substrate 1, be at least also provided with an anti-slop serrations 13 horizontally outward extending; After substrate 1 flattens, anti-slop serrations 13 also can snap in the hole wall of nut fixing hole 4, plays the effect of fixed substrate 1.
As shown in Fig. 3～Fig. 4, the embodiment of the present invention also provides a kind of light fixture, comprise upper casing 5 and lower casing 6, upper casing 5 is fixedly connected with bolt 3 by nut 2 with lower casing 6, upper casing 5 or lower casing 6 offer nut fixing hole 4, are provided with foregoing nut fixing device in nut fixing hole 4, and nut 2 is fixed in nut fixing hole 4 by this nut fixing device, nut 2 is specifically fixed to mode in nut fixing hole 4 as previously mentioned, repeats no more herein.
The light fixture that the embodiment of the present invention provides, employing arranges nut fixing device in nut fixing hole 4, nut fixing device is firmly fixed on nut 2 in nut fixing hole 4, neither can allow nut 2 not drop when having bolt 3 to screw, can not allow nut 2 former thereby come off from bolt 3 due to vibrations etc. after being spirally connected with bolt 3, the safety coefficient of light fixture is improved yet.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
