The explosion-proof lamp mounting means generally can adopt derrick type, wall-hanging and ceiling type etc. at present, but its fixed form is all more single, and the security performance requirement can't be well satisfied in damage or loosening easily in rugged environment.
Summary of the invention
The technical problem that the present invention will solve is that the above-mentioned defective to prior art provides a kind of fixing device of explosion-proof lamp, in the strong motion environment, installs firmly to guarantee explosion-proof lamp, avoids accident to take place.
The technical solution adopted for the present invention to solve the technical problems is:
Be used for lamp body is installed in brace, comprise snap ring, following snap ring and anchor ear, the said snap ring of going up is connected through first lock-screw with following snap ring, and formation one is used for circumferentially fixing the screens of said brace;
Said snap ring down is provided with the 3rd lock-screw that is used for radially being fixedly connected said lamp body, and said snap ring down is set to U-shaped, is arranged on the lower surface of snap ring under the U-shaped with the adaptive screw hole of said the 3rd lock-screw;
Said anchor ear has one and is used for circumferentially holding tightly the fixed bit of said lamp body, and is fixedly connected said snap ring down; Said anchor ear comprises left semi-ring and right semi-ring, and the upper end of said left semi-ring and right semi-ring is fixedly connected said snap ring down through the 4th lock-screw, and the lower end is connected through second lock-screw, forms said fixed bit.
Fixing device of explosion-proof lamp of the present invention, wherein, the said snap ring upper end of going up is fixedly connected said brace through the 5th lock-screw.
Fixing device of explosion-proof lamp of the present invention, wherein, the said snap ring of going up is set to semicircle.
Fixture of the present invention is circumferentially fixing fixing with radially through simultaneously lamp body being carried out; Even wherein a kind of fixed form lost efficacy, another kind of fixed form is still effective, installs firm to guarantee explosion-proof lamp; Even in the strong motion environment, also can keep stable, avoid accident to take place.
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 fixing device of explosion-proof lamp structural representation of the embodiment of the invention;
Fig. 2 is the lamp body of the embodiment of the invention and the structural representation that is connected of fixing device of explosion-proof lamp;
Fig. 3 is fixing device of explosion-proof lamp and brace and the lamp body syndeton sketch map that adopts the embodiment of the invention.
The specific embodiment
Below in conjunction with diagram, the preferred embodiments of the present invention are described in detail.
The fixing device of explosion-proof lamp 10 of the embodiment of the invention is used for the lamp body 20 of explosion-proof lamp is installed in brace 30; Mainly be applicable to and have cylindrical outer surface and microscler explosion-proof lamp lamp body; Like fluorescent tube etc., the annexation of fixing device of explosion-proof lamp 10, lamp body 20 and brace 30 is as shown in Figure 3.
The structure of the fixing device of explosion-proof lamp 10 of the embodiment of the invention is as shown in Figure 1; It comprises semiorbicular snap ring 11, the following snap ring 12 gone up; Last snap ring 11 is connected through first lock-screw 15 respectively with following snap ring 12 two ends, and formation one is used for fixing the screens 18 of bracing diagonal 30.Also comprise an anchor ear 14; Anchor ear 14 specifically can be made up of with right semi-ring 142 left semi-ring 141, and two upper ends of left semi-ring 141 and right semi-ring 142 are fixedly connected on down on the snap ring 12 through the 4th lock-screw 16, and two lower ends are connected through second lock-screw 17; Formation one is used for the fixed bit 19 of circumferential fixed lamp body 20; Can be through regulating the degree of tightness of second lock-screw 17, the size of regulating this fixed bit 19, with adaptive different sizes lamp body.
The external surface shape that be to cooperate brace 30 makes fixing more firmly, and last snap ring 11 can be set to semicircle.Also be provided with the 3rd lock-screw 13, the three lock-screws 13 in following snap ring lower end and be fixedly connected lamp bodies 20 two ends peripheries, to accomplish radially fixing, as shown in Figure 2 to lamp body 20.
For making this radially fixing more stable, can be with descending snap ring 12 can be set to U-shaped, screw hole can be arranged on the lower surface of snap ring 12 under this U-shaped.
The 5th lock-screw (not shown, the effect of the 5th lock-screw with the 3rd lock-screw 13) also can be set on last snap ring 11, and snap ring 11 and brace 30 connections in to accomplish radially the fixing of brace 30, prevent its circumferential fixed form inefficacy.
During installation, can use two these fixing device of explosion-proof lamp, respectively the two ends of fixed lamp body 20.Unscrew second lock-screw 17 earlier, lamp body 20 is installed on the fixing device of explosion-proof lamp 10, second lock-screw 17 of screwing is again accomplished circumferentially fixing lamp body 20.Fastening again the 3rd lock-screw 13, radially fixed lamp body.Then unscrew two first lock-screws 15, brace 30 is put into screens 18 after, fastening again this first lock-screw 15 is accomplished circumferentially fixing to brace 30.And then lock the 5th lock-screw, accomplish radially fixing to brace 30.
Like this, even if behind the radially solid failure of the 3rd lock-screw 13, anchor ear 14 still can carry out circumferentially fixing to lamp body 20, and so that reliable connection to be provided, the assurance explosion-proof lamp is installed in the strong motion environment firmly, avoids accident to take place.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
