Abstract
The invention relates to a nut fixing device, which comprises a substrate (410). The substrate (410) is provided with a central through hole (430). The exterior of the substrate (410) is provided with a clamping ear (420) extending outwards. Because the nut fixing device can fix a nut, the nut fixing structure is tighter, further the device fixed by the nut is firmer, and simultaneously the nut can be better fixed, does not drop off to cause scattering after a bolt is disassembled. Therefore, the nut fixing device facilitates maintenance of equipment.
Description
Technical field
The present invention relates to fixing device, more particularly, relate to a kind of fixing device of nut.
Background technique
Nuts and bolt is fixing device commonly used, but in the prior art, be screwed in nut on the bolt after, the device that other are used for tightening nut generally is not set again, bolt breaks away from easily bolt and equipment and is scattered at the dismounting back nut like this, thereby brings difficulty to service equipment.
Summary of the invention
The technical problem to be solved in the present invention is that holding caducous defective for the above-mentioned nut of prior art provides a kind of nut fixing device, comprises substrate, and described substrate is provided with central through bore, and described substrate outside is provided with outward extending card ear.
In nut fixing device of the present invention, described card ear and plane, substrate place form angle.
In nut fixing device of the present invention, the scope of described angle is that 5 degree are to 10 degree.
In nut fixing device of the present invention, described card ear is sheet.
In nut fixing device of the present invention, described card ear is more than the sheet.
In nut fixing device of the present invention, the slightly larger in diameter of described central through bore is in the external diameter of bolt.
In nut fixing device of the present invention, described card ear end maximum spacing be slightly larger than be used to the opposite side distance of the counterbore that holds described nut from.
Implement explosion-proofing floodlighting lamp of the present invention, nut fixing device of the present invention has following beneficial effect: owing to can be fixed nut, so that the fixed structure of nut is more fastening, thus so that more convenient and simple in maintenance process with the fixing equipment of this nut.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of nut fixing device of the present invention;
Fig. 2 is that nut fixing device of the present invention is locked in the structural representation in the nut bore;
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment
The structural representation of nut fixing device of the present invention is described in conjunction with Fig. 1 to Fig. 3.Nut fixing device 400 comprises substrate 410, and substrate 410 centers are provided be used to the through hole 430 that holds bolt 150, and described substrate 410 outsides are provided with card ear 420, and card ear 420 has an angle with plane, substrate 410 place, and scope is 5～10 degree.The profile structure of counterbore 140 is suitable with the profile structure of substrate 410.Card ear 420 end maximum spacings be slightly larger than be used to the opposite side distance of the counterbore 140 that holds described nut from.Like this nut fixing device 400 is embedded in the counterbore 140, card ear 420 compresses slightly, thereby is stuck in the counterbore 140.Card ear 420 can be for more than 2 or 2.In the present embodiment, card ear 420 is 2.
In conjunction with Fig. 2 the fixedly mode of execution of the nut of light fixture of nut fixing device 400 is described, lamp housing 100 is provided with counterbore 140, bolt 150, nut 160 are contained in the counterbore 140, bolt 150, nut 160 are used for affixed lamp casing 100 and light cover 200, in order to prevent that nut 160 from coming off, and is provided with anticreep parts 400 in the counterbore 140.
When these anticreep parts 400 are installed, with these anticreep parts 400 toward being pushed down in the counterbore 140, keep certain interval so that nut 160 can have certain activity space to make things convenient for bolt 150 assemblings with the outer end face of nut 160, and the end surface side of card ear 420 is upturned, and pins mutually with the inwall of counterbore 140; Like this, just can reach the effect that prevents that nut 160 from coming off.
Claims (5)
1. a nut fixing device is characterized in that, comprises substrate (410), and described substrate (410) is provided with central through bore (430), and described substrate (410) outside is provided with outward extending card ear (420); Described card ear (420) has an angle with substrate (410) plane, place, and the scope of described angle is 5 to 10 degree; When described nut fixing device embeds in the counterbore (140), the outer end face of described nut fixing device and nut (160) keeps certain gap so that nut (160) has certain activity space to make things convenient for the assembling of bolt (150), described card ear (420) thus compression is stuck in the described counterbore (140) slightly.
2. nut fixing device according to claim 1 is characterized in that, described card ear (420) is 2.
3. nut fixing device according to claim 1 is characterized in that, described card ear (420) is more than 2.
4. any one described nut fixing device is characterized in that according to claim 1-3, and the slightly larger in diameter of described central through bore (430) is in the external diameter of bolt.
5. nut fixing device according to claim 4 is characterized in that, described card ear (420) end maximum spacing be slightly larger than be used to the opposite side distance of the counterbore that holds described nut (140) from.
