DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0021] like Figures 1 to 4 As shown, an electric emergency lighting fixture comprises a chassis 1, a lifting frame 2 and a mounting block 3. One end of the lifting frame 2 is threadedly connected to the chassis 1, and the other end is spherically hinged to the bottom of the mounting block 3. A mounting window 4 is provided through the side wall of the mounting block 3 in the horizontal direction. The lighting lamp is placed in the mounting window 4. An upper pressure plate 5 is provided in the mounting window 4. The upper pressure plate 5 has the freedom to move along the height direction of the mounting block 3. The bottom surface of the mounting window 4 is provided with a front limit plate 6 and a rear limit plate 7 at intervals along the direction of its opening. The moving direction of the front limit plate 6 is opposite to that of the rear limit plate 7. When the fixture needs to be transported and carried, the chassis 1 and the lifting frame 2 are disassembled, the lighting lamp is removed from the mounting window 4 to avoid damage during transportation, and then the lifting frame 2 is retracted to reduce its length, thereby disassembling the fixture into three parts for transportation. When in use, the lifting frame 2 is threadedly connected to the chassis 1, and then the lighting lamp is placed in the installation window 4, and the lighting lamp is located between the front limit plate 6 and the rear limit plate 7, and the lower pressure plate 5 is moved close to the lighting lamp so that the lower pressure plate 5 abuts the lighting lamp, thereby installing the lighting lamp on the mounting block 3, and then the front limit plate 6 and the rear limit plate 7 are moved so that the front limit plate 6 and the rear limit plate 7 respectively abut the front and rear ends of the lighting lamp, thereby strengthening the installation strength of the lighting lamp and preventing the problem of falling, making the disassembly and assembly of the lighting lamp simple and quick. When in use, the mounting block 3 can be rotated to change the lighting angle of the lighting lamp. Since the lifting frame 2 and the mounting block 3 are spherically hinged, they have a large adjustment range and can achieve 360° angle adjustment within a certain range, which can adapt to use in complex environments.

[0022] Further, if Figure 1 and Figure 3As shown, the top surface of the mounting block 3 is threadedly connected with a screw 8, and the tail of the screw 8 is inserted into the mounting window 4 and rotatably connected to the upper pressure plate 5. Both sides of the upper pressure plate 5 contact the side walls of the mounting window 4, and an elastic pad 11 is fixed to the bottom of the upper pressure plate 5. The position of the upper pressure plate 5 is adjusted by tightening or unscrewing the screw 8. Since both sides of the upper pressure plate 5 contact the side walls of the mounting window 4, the rotational freedom of the upper pressure plate 5 is limited, so that the screw 8 only drives the upper pressure plate 5 to move up and down, and the position of the upper pressure plate 5 is locked by the threaded cooperation of the screw 8 and the mounting block 3. The upper pressure plate 5 contacts the lighting lamp through the elastic pad 11 to avoid squeezing and deforming the outer shell of the lighting lamp.

[0023] Further, if Figure 1 and Figure 3 As shown, a screw groove 9 is provided on the bottom surface of the installation window 4, and the screw groove 9 extends toward the opening direction of the installation window 4. A bidirectional threaded screw 10 is provided in the screw groove 9, and the bidirectional threaded screw 10 is rotatably connected to the installation block 3. The bidirectional threaded screw 10 has two thread segments with opposite thread rotation directions. The front limit plate 6 and the rear limit plate 7 are respectively threadedly fitted on the two thread segments. The front limit plate 6 and the rear limit plate 7 are both slidably adapted to the screw groove 9. One end of the bidirectional threaded screw 10 passes through the installation block 3 and is fixed with a turntable 12 , rotating the turntable 12 drives the bidirectional threaded screw 10 to rotate, so that the front limit plate 6 and the rear limit plate 7 both move along the axial direction of the bidirectional threaded screw 10. Since the thread rotation direction of the front limit plate 6 is opposite to that of the rear limit plate 7, the moving direction of the front limit plate 6 is opposite to that of the rear limit plate 7. To ensure that the front limit plate 6 and the rear limit plate 7 can respectively abut the front and rear sections of the lighting lamp, first adjust the positions of the front limit plate 6 and the rear limit plate 7, and then move the upper pressure plate 5 downward to make it abut the lighting lamp.

[0024] Further, if Figure 3 and Figure 4 As shown, the lifting frame 2 includes a fixed cylinder 13 and a lifting cylinder 14. The bottom end of the fixed cylinder 13 is fixedly connected to the chassis 1, and the lifting cylinder 14 is slidably penetrated at the high end of the fixed cylinder 13. The lifting cylinder 14 is spherically hinged to the mounting block 3 at one end away from the fixed cylinder 13. The side wall of the fixed cylinder 13 is threadedly connected with a locking bolt 15, and the tail end of the locking bolt 15 abuts against the lifting cylinder 14. The lighting height of the lighting lamp is adjusted by the telescopic movement of the lifting frame 2. Specifically, the locking bolt 15 is loosened so that the lifting cylinder 14 can slide in the fixed cylinder 13 to adjust the lighting height. After the adjustment is completed, the locking bolt 15 is tightened. The locking bolt 15 presses the lifting cylinder 14 against the fixed cylinder 13, thereby locking the adjustment height of the lifting frame 2.

[0025] Further, if Figure 3 and Figure 4As shown, a hinge ball 16 is fixed to the bottom of the mounting block 3, and a spherical groove 17 is provided at the end of the lifting cylinder 14 away from the fixed cylinder 13. The hinge ball 16 is adapted to the spherical groove 17, and the hinge ball 16 is wrapped with an elastic rubber sleeve 18. The side wall thread of the lifting cylinder 14 is adapted to be equipped with a locking screw 19, and the tail of the locking screw 19 penetrates into the spherical groove 17 and abuts against the elastic rubber sleeve 18. When it is necessary to adjust the lighting angle and direction of the lighting lamp, loosen the locking screw 19 so that the hinge ball 16 can deflect in the spherical groove 17, thereby adjusting the lighting angle and lighting direction of the lighting lamp. When the adjustment is completed, tighten the locking screw 19, and the tail of the locking screw 19 squeezes the elastic rubber sleeve 18 to deform, so as to limit the deflection freedom of the hinge ball 16, thereby locking the direction and angle of the lighting lamp. It is simple to operate and has a wide range of adaptability, and can meet the use in complex environments.
