Description
Technical field
The present invention relates to a kind of light fixture, relate in particular to a kind of light fixture, applicable to multiple light fixtures such as mine explosion-suppression lamps with nut anti-falling structure.
Background technology
Light sources such as the bulb in the light fixture have certain life-span, damage easily, more change the bulb and need take lamp housing apart, connect through the bolts and nuts matching and fixing between the protecgulum of lamp housing and the bonnet, and in the unloading process, nut comes off easily, influences the installation of light fixture.The employing instrument is with the part distortion on the lamp housing in more present light fixtures; Thereby be clamped on the purpose that reaches hold-down nut on the shell, this operation is cumbersome, and the distortion situation of parts is inconsistent; The threaded engagement phenomenon can occur, have a strong impact on the dismounting efficient and the reliability of light fixture.
Summary of the invention
The technical problem that the present invention will solve is, to the above-mentioned defective of prior art, provide a kind of assemble reliable, simple to operation, can prevent effectively that nut from rotating and skew and do not influence the light fixture with nut anti-falling structure of nut and bolts assemblies.
The technical solution adopted for the present invention to solve the technical problems is: a kind of light fixture with nut anti-falling structure; Comprise lamp body, lamp housing; Lamp housing is made up of protecgulum and bonnet, and protecgulum is in the same place through the bolts and nuts matching and fixing with bonnet, and protecgulum or bonnet are provided with the nut locating slot; Be provided with keeper in the nut locating slot; Nut can not squint and rotate in the nut locating slot through keeper is spacing, and the nut locating slot is provided with the connecting hole of perforation, the screw of the nut after spacing and the corresponding UNICOM of connecting hole of nut locating slot.
One side opening of said nut locating slot, keeper are the semi-surrounding structure, and nut is installed on the nut locating slot from end face and side, and it can not be squinted and rotate in the nut locating slot.
Said keeper comprises substrate and side shield, the side opening of the corresponding nut locating slot of the side shield of keeper, and substrate is fitted on the nut end face.
The substrate shape of said keeper is consistent with the nut end face form fit, and has the through hole with the corresponding UNICOM of screw of nut.
The Access Division that is stuck in nut locating slot sidewall is extended on the substrate both sides of said keeper, and the angle between Access Division and the substrate is 150～155 °.
Said Access Division is each gang saw tooth that are provided with of substrate both sides.
Said keeper side shield is vertical with substrate, and the side shield shape is consistent with nut lateral wall form fit, and two lateral surfaces that side shield is adjacent with nut are at least simultaneously fitted.
The substrate and the side shield of said keeper are structure as a whole.
Said nut locating slot madial wall shape is consistent with nut lateral wall shape, the two matched in clearance.
The present invention is employed in the nut locating slot keeper is set; Keeper is spacing to nut; It can not be squinted and rotate, and the corresponding UNICOM of connecting hole of the screw of the nut after spacing and nut locating slot in the nut locating slot, make bolt can pass connecting hole directly and the screw of nut be spirally connected.Spacing back nut can offset rotation more can not come off, and can avoid nut loss when more changing the bulb the dismounting lid.And directly the spinning bolt is easy and simple to handle, and assembling is reliable.
What keeper adopted is the semi-surrounding structure; Comprise orthogonal substrate and side shield, cooperate nut spacingly respectively from the end face of nut and side and nut locating slot that and substrate shape is consistent with the nut end face shape; Can directly press-fit with nut end face; And have the through hole that supplies bolt to install on the substrate, in spacing, do not influence the cooperation of bolts and nuts.Two lateral surfaces that side shield and nut lateral wall form fit, side shield are adjacent with nut are at least simultaneously fitted, and prevent the nut rotation.
The Access Division that is stuck in nut locating slot sidewall is extended on the substrate both sides of keeper; Angle between Access Division and the substrate is 150～155 °; The Access Division of this spline structure outwards turns down; Make it get into the nut locating slot easily, and barb is difficult for from the nut locating slot, deviating from after getting into the nut locating slot on cell wall.A gang saw tooth is arranged in the Access Division, has more strengthened the hook to cell wall, and reliability is higher.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is an A place partial enlarged drawing among Fig. 1;
Fig. 3 is the keeper structural representation of the embodiment of the invention.
The specific embodiment
Like Fig. 1,2, shown in 3, a kind of light fixture with nut anti-falling structure comprises lamp body 10, lamp housing; Lamp housing is made up of protecgulum 4 and bonnet 1; Protecgulum 4 is in the same place through bolt 5 and nut 2 matching and fixing with bonnet 1, and protecgulum 4 or bonnet 1 are provided with the nut locating slot, and present embodiment is on bonnet 1, to have nut locating slot 6; Be provided with keeper 3 in the nut locating slot 6; Nut 2 can not squint and rotate in nut locating slot 6 through keeper 3 is spacing, and nut locating slot 6 is provided with the connecting hole 61 of perforation, the screw 21 of the nut 2 after spacing and the connecting hole 61 corresponding UNICOMs of nut locating slot 6.Nut 2 is a hex nut, and nut locating slot 6 madial wall shapes are consistent with nut 2 lateral wall shapes, the two matched in clearance, and a side opening of nut locating slot 6.
Like Fig. 2, shown in 3; Keeper 3 is the semi-surrounding structure; Said keeper 3 comprises orthogonal substrate 31 and side shield 32, and substrate 31 is structure as a whole with side shield 32, and substrate 31 is fitted on nut 2 end faces; Nut 2 is installed on the nut locating slot 6 from end face, it can not be moved axially in nut locating slot 6.Substrate 31 shapes of said keeper and nut 2 end surface shape cooperate consistent, are hexagon, and substrate 31 centers have the through hole 33 with the screw 21 corresponding UNICOMs of nut, and through hole 33 internal diameters equate with screw 21 internal diameters or be bigger.The Access Division 35 that is stuck in nut locating slot 6 sidewalls is extended on substrate 31 both sides of said keeper, and the Access Division 35 of present embodiment is each gang saw tooth that are provided with of substrate 31 both sides, can also be the outward extending a plurality of card posts in rectangular clamp, substrate 31 both sides.See that from Fig. 3 Access Division 35 is turnover upwards, the angle between Access Division 35 and the substrate is 150～155 °, is convenient to the keeper 3 nut locating slot 6 of packing into.
