Description
Technical field
The utility model relates to a kind of sense light, is meant a kind of sense light that can adjust the lamp bracket angle especially.
Background technology
In order to protect personal safety, usually can be in do in narrow and small lane or other sense light is set corner of dark.The light angle of the sense light that has is fixed, and can only just limit the range of application of sense light at folk prescription to illumination, has the dealer to improve at the sense light of traditional lighting fixed angle formula then.
As the patent No. is that 5,649,761 United States Patent (USP) promptly belongs to the adjustable infrared induction light fixture of a kind of light angle (seeing also shown in Figure 6), and it includes a pedestal A, is provided with an infrared inductor B, two lamp bracket C in this pedestal A; Its principle is, as long as have infrared ray to come out in specific distance, this infrared inductor B will detect infrared ray and to start bulb automatically luminous.The light angle guiding mechanism of this infrared induction light fixture is included in and links a support bar D between lamp bracket C and the pedestal A, the end of support bar D is to link with bayonet lock D1 to be fixed on the pedestal A, include first a ring gear D2 who is combined on the support bar D between the other end of support bar D and the lamp bracket C, and be combined in the second ring gear D3 on the lamp bracket C, the dentalation of this first ring gear D2 and this second ring gear D3 end face is meshing with each other, one bolt E, the one end forms knob E1, the other end of this bolt E passes the first ring gear D2 and the second ring gear D3, make the end face fluid-tight engagement of the first ring gear D2 and the second ring gear D3, with the fixing light angle of lamp bracket C.When desire is adjusted the lamp bracket light angle,, make that maintain between the first ring gear D2 and the second ring gear D3 can counterrotating space towards the knob E1 that loosens on the direction rotation bolt E, meshed after the rotation, just can adjust the luffing angle of lamp bracket C, again bolt E be rotated towards fastening direction, with the priming illumination angle.
Yet, through inventor's discovery of concentrating on studies, this kind infrared induction lamp is that the mode of utilizing the flank of tooth of two ring gears to be meshed is adjusted light angle, and dentalation is long-term can be worn away under using, cause to do the problem that fine adjustment and angle can't be fixed, therefore be necessary to be improved.
The utility model content
Therefore, the purpose of this utility model is, improves at the angle-adjusting mechanism at the lamp bracket place of existing sense light, can have multisection type to adjust the angle except making lamp bracket, and the mechanism of adjustment is difficult for impaired, and long service life is to keep the adjustable function of lamp bracket.
For achieving the above object, technological means of the present utility model is, one angle-adjusting mechanism is set between lamp bracket and support bar, this angle-adjusting mechanism is included in support bar one end and is provided with a plurality of concave faces, and described concave face is to arrange in the form of a ring, is provided with at least one flange on lamp bracket, the position of this flange is corresponding to a concave face wherein, one bolt in order to articulate support bar and lamp bracket, makes flange can be matched with pairing concave face.When this lamp bracket of switching, can change the position of flange and make flange be matched with another concave face, reach the purpose of adjusting the bowing of lamp bracket, elevation angle degree by this, screw this bolt and can fix adjusted angle.
The mechanism that the utility model utilizes a plurality of concave faces and flange to be slidingly matched makes sense light that multidirectional illumination can be arranged, and to promote range of application, also more traditional on the other hand increment face structure is difficult for abrasion, has higher service life.

The specific embodiment
Those skilled in the art below cooperate Figure of description that embodiment of the present utility model is done more detailed description, so that can implement after studying this specification carefully according to this.
See also Fig. 1, be the schematic diagram of sense light of the present utility model.The sense light of present embodiment mainly comprises a pedestal 1 and at least one lamp bracket 2, link with a support bar 3 between this pedestal 1 and this lamp bracket 2, have angle-adjusting mechanism 4 between this support bar 3 and the lamp bracket 2, can set light angle, be feature of the present utility model place.
See also Fig. 2, with the outward appearance of monolateral lamp bracket, angle-adjusting mechanism 4 mainly is with a bolt 41, and support bar 3 one ends and lamp bracket 2 one abutting ends 21 are articulated, and when loosening this bolt 41, adjusts the bowing of lamp bracket 2, elevation angle degree, otherwise then fastening.And in order to form gradual angle adjustment, especially at having designed fine tuning structure between support bar 3 and the lamp bracket abutting end 21, fine tuning structure as shown in Figures 3 and 4, be included on the axial plane 31 of support bar 3 one ends a plurality of concave faces 311 are set, the shape of this concave face 311 is good with the hemispherical depression face, described concave face is to arrange in the form of a ring, in addition on an axial plane 211 of described lamp bracket abutting end 21, it is (mixed and disorderly for avoiding drawing to form at least one flange 212, present embodiment only shows a flange), the shape of this flange 212 is good with hemispherical, and the position of flange 212 is corresponding to a concave face 311 wherein, to cooperate now.Described bolt 41 passes support bar 3 one ends and described lamp bracket abutting end 21, and support bar 3 be can be combined in lamp bracket abutting end 21, and flange 212 can be matched with pairing concave face 311.
About the shape of support bar 3 and lamp bracket abutting end 21 particularly is, one end of described support bar 3 has an axial mating groove 32, the described concave face 311 of support bar 3 surperficial annular arrangements around this mating groove 32, on the support bar 3 of this mating groove 32, a mating holes 33 that runs through this mating groove 32 is set; Abutting end 21 central authorities of described lamp bracket 2 form a projection 22, these projection 22 central authorities have a fixing hole 221, under these fixing hole 221 preferable situations is internal thread hole, form a conduit 23 around the projection 22, a sheathed packing ring 42 on projection 22, in order to support this projection 22, the position of this packing ring 42 is position ports at conduit 23.One end of described bolt 41 is designed to helicitic texture 411, and the other end then forms a rotation interface 412 (referring to Fig. 2); After this end bolt 41 with helicitic texture 411 passes this mating holes 33 and fixing hole 221, be locked in fixing hole 221 internal threads, support bar 3 axial planes 31 and abutting end 21 axial planes 211 are bonded with each other.
See also Fig. 5, be the angle-adjusting mechanism action schematic diagram of sense light.When bolt 41 (omit among this figure, see also Fig. 3) under locking state, support bar 3 axial planes 31 and abutting end 21 axial planes 211 fluid-tight engagement, flange 212 is matched with wherein in the concave face 311, at this moment, lamp bracket 2 is fixed on a certain special angle; When little bolt that unclamps, unclamp between support bar 3 axial planes 31 and abutting end 21 axial planes 211, make abutting end 21 have the space of rotation, when this lamp bracket 2 of switching, make lamp bracket 2 with respect to this bolt 41 (or support bar 3) rotation, can force flange 212 to slide past other concave face 311 in regular turn, at this moment, the operator can produce the feel as the fine setting, and action reaches the purpose of adjusting the bowing of lamp bracket, elevation angle degree by this; After lamp bracket 2 is adjusted to predetermined angular, with bolt 41 lockings, make axial plane 31 and abutting end 21 axial plane 211 driving fits once more, flange 212 is matched with in the pairing concave face 311, can fix adjusted angle.
