Fig. 1 to 4(d) show, by way of example, a movable support 10 of the present invention and an explosion-proof lamp 100 applied thereto. The movable bracket 10 in this example can mount an object 20 such as a lamp body of the explosion-proof lamp 100 at a desired mounting position such as a wall or ceiling of a building, etc., and make the lamp body of the explosion-proof lamp 100 fixed to the building via the movable bracket 10 in different orientations with respect to the building to adjust its mounting height and inclination angle, thereby maintaining the illumination side of the explosion-proof lamp 100 in a desired orientation, thereby greatly expanding the range of applications.

Specifically, the explosion-proof lamp 100 may be configured to include a lamp body having a cylindrical outer surface and a movable bracket 10 mounted to the outer surface of the lamp body at two diametrically opposite connection portions to allow the lamp body to be rotated with respect to the movable bracket 10 into a desired orientation with a line connecting the two connection portions thereof with the connection points of the movable bracket 10 as a rotation axis when the lamp body is not assembled with the movable bracket 10, and to assemble the lamp body and the movable bracket 10 in the orientation to maintain the illumination side of the lamp body in the desired orientation regardless of the mounting position where the lamp body is to be mounted.

As shown in fig. 1 and 2, the movable bracket 10 may include two first coupling plates 11 and a second coupling plate 12 coupling the two first coupling plates 11. The two first connecting plates 11 are substantially symmetrically arranged, that is, symmetrically arranged about a direction perpendicular to a radial direction of the two connecting portions of the lamp body, first ends of the two first connecting plates 11 are detachably connected to two diametrically opposite connecting portions on an outer surface of the object 20, respectively, and second ends of the two first connecting plates extend away from the object 20 and extend beyond the lamp body, that is, extend at least a distance greater than a radius of a cylindrical outer surface of the lamp body, so that the second connecting plates 12 are mounted to the second ends of the two first connecting plates 11. The second connection plate 12 may be configured to include a main body portion 121 extending transverse to the extending direction of the first connection plate 11, e.g., extending substantially perpendicular to the extending direction of the first connection plate 11, and the main body portion 121 may have mounting holes 125 spaced apart along the extending direction thereof to mount, e.g., screw-connect, to a mounting position where the object 20 is to be mounted. The second connection plate 12 is further configured to include connection portions 122 extending from both ends of the body portion 121 substantially parallel to the extending direction of the first connection plates 11 to be detachably connected to the second ends of the two first connection plates 11.

Illustratively, when an operator is to mount the object 20 at a desired mounting position, the object 20, the two first connecting plates 11, and the second connecting plate 12 may be preliminarily brought into an unlocked state, such as a state of being detached from each other, and then the above-described structure may be assembled such that the two first connecting plates 11 are rotated with respect to the object 20 into a desired first orientation with their connecting points to the respective connecting portions of the object 20 as a rotation center, and the two first connecting plates 11 are locked with the object 20 in the first orientation, so that relative movement between the two first connecting plates 11 and the object 20 in the locked state does not occur. Subsequently, the second connecting plate 12 is rotated with its connection point with the second end of the first connecting plate 11 as a rotation center relative to the first connecting plate 11 to a desired second orientation simultaneously with respect to the object 20, and the second connecting plate 12 is locked to the two first connecting plates 11 in the second orientation, so that relative movement between the second connecting plate 12 and the two first connecting plates 11 and thus the object 20 in the locked state does not occur, and mounting of the object 20 to a desired mounting position and maintaining of the object 20 in the desired mounting orientation are achieved. The assembly sequence among the object 20, the first connecting plate 11 and the second connecting plate 12 can be adjusted according to actual conditions, and only the required installation of the object 20 to the installation position and the installation orientation relative to the installation position need to be realized.

As shown in fig. 3(a) to 3(d), the first connector panel 11 and the object 20 in different first orientations and the second connector panel 12 and the first connector panel 11 in different second orientations can be seen. Wherein fig. 3(a) shows that the second connection plate 12 is vertically arranged with respect to the first connection plate 11 with the body portion 121 of the second connection plate 12 facing downward so that the illumination side of the lamp body faces downward and can be mounted to a horizontal bottom surface such as the ground; fig. 3(b) shows the second connecting plate 12 being substantially at 45 degrees with respect to the first connecting plate 11 and the body portion 121 of the second connecting plate 12 facing downward such that the illuminating side of the lamp body is mounted to the horizontal bottom surface at a 45 degree angle to the horizontal plane; fig. 3(c) shows the second connection plate 12 coaxially arranged with respect to the first connection plate 11 with the body portion 121 of the second connection plate 12 facing to the right, such that the illumination side of the lamp body faces downward and is mounted to a vertical surface such as a wall; fig. 3(d) shows the second connection plate 12 arranged coaxially with respect to the first connection plate 11 with the body portion 11 of the second connection plate 12 facing upwards, such that the illumination side of the lamp body faces downwards and is mounted to a horizontal ceiling, such as a ceiling or a suspension mounting. The corresponding orientation of the object 20, the first connecting plate 11 and the second connecting plate 12 shown in fig. 4(a) to 4(d) is the same as the orientation shown in fig. 3(a) to 3(d), and the difference lies in that the appearance structure of the object 20 is different, that can be understood, the utility model provides a movable support can install the object 20 to different application scenes and satisfy the requirement of its different installation orientation, can be applied to the object 20 of different appearance structures simultaneously like the lamp body of different sizes and structures, has greatly expanded the application scope of the movable support 10 of the utility model. It should be noted that the mounting orientations of the movable bracket 10 shown in fig. 3(a) to 3(d) and fig. 4(a) to 4(d) are only schematic orientations, and in practical applications, an operator can adjust the first orientation between the first connecting plate 11 and the object 20 and the second orientation between the second connecting plate 12 and the first connecting plate 11 according to practical needs, so as to adjust the irradiation angle of the lamp body and the height and horizontal distance thereof relative to the mounting position.

In another embodiment, since the two first connecting plates 11 are connected to the two oppositely disposed connecting portions on the outer surface of the object 20 in the same manner, only the connecting manner of one of the first connecting plates 11 to the corresponding connecting portion of the object 20 will be described as an example. Wherein, the first end of the first connection plate 11 may be provided with a first through hole, and the connection portion of the object 20 is provided with an opposite first connection hole 201 such as a threaded hole.

For example, the first connecting plate 11 may be configured to be connected to the object 20 via the first fastening member 13, such as a screw whose end is provided with an external thread matching the thread of the threaded hole, and the operator may previously pass the first fastening member 13 through the first through hole and into the first connecting hole 201 without locking with the first connecting hole 201, at which point the operator may rotate the first connecting plate 11 with respect to the object 20 to a desired first orientation with the first fastening member 13 as a rotation center, and lock the first fastening member 13 by screwing into the first connecting hole 201 after moving to the first orientation, so that the first connecting plate 11 and the object 20 are in the locked first orientation.

Alternatively, the first connection plate 11 may be connected to the object 20 via a first fastener 13 such as a screw whose end is provided with an external thread adapted to the thread of the threaded hole and a stopper piece 14, for example, to further improve the connection strength between the first connection plate 11 and the object 20. Specifically, the stopper piece 14 may be configured to include a clamping portion 141 located between the first connecting plate 11 and the object 20 and provided with a second through hole at a region opposite to the first through hole, and a stopper portion 142 extending from both ends of the clamping portion 141 to overlap into a stopper groove 202 of the object 20 to be prevented from rotating relative to the object 20, and the stopper groove 202 of the object 20 may be configured by adjacent ones of axial ribs spaced in the circumferential direction of the lamp body as shown in fig. 2. In practical application, an operator may advance the first fastening member 13 to penetrate into the first connection hole 201 through the first through hole and the second through hole without locking with the first connection hole 201, while the stopping portion 142 of the limiting piece 14 is placed in the limiting groove 202 of the object 20, then rotate the first connection plate 11 with the first fastening member 13 as a rotation center relative to the object 20 to a desired first orientation, and screw the first fastening member 13 into the first connection hole 201 to lock after moving to the first orientation, so as to clamp the clamping portion 141 of the limiting piece 14 between the first connection plate 11 and the object 20 and limit the stopping portion 142 in the limiting groove 202 of the object 20, while keeping the first connection plate 11 and the object 20 in the locked first orientation.

In the case where the first connection plate 11 is connected to the object 20 via the first fastening member 13 and the stopper piece 14, the movable bracket 10 may be configured to further include a first stopper pin 15 having an external thread at an end thereof. The first end of the first connecting plate 11 is provided with a first arc-shaped hole 112 extending around the circumference of the first through hole in a region opposite to the clamping portion 141 of the limiting plate 14, the clamping portion 141 of the limiting plate 14 is provided with a second connecting hole such as a threaded hole adapted to the external thread of the first positioning pin 15, so that the first positioning pin 15 passes through the first arc-shaped hole 112 and is connected to the second connecting hole and can extend into the object 20 between adjacent axial fins in the axial fins distributed at intervals in the circumference direction, so as to lock the first connecting plate 11 and the limiting plate 14, and provide additional connecting strength between the first connecting plate 11 and the object 20 through the first positioning pin 15 and the limiting plate 14.

Among them, the first arc-shaped hole 112 may be configured as a hole extending in a semicircular shape to be always lockable with the second coupling hole, i.e., with the stopper piece 14, in the case where the first coupling plate 11 is rotated counterclockwise as shown in fig. 3(a) to 3(c) from a radial arrangement with respect to the object 20 to an axial arrangement with respect to the object 20 as shown in fig. 3(d) or clockwise to an axial arrangement with respect to the object 20, thereby providing additional coupling strength.

In another embodiment, similar to the first connecting plates 11 and the object 20, since the two connecting portions 122 of the second connecting plates 12 are connected to the second ends of the two first connecting plates 11 in the same manner, only the connecting portion 122 of one of the second connecting plates 12 is connected to the adjacent first connecting plate 11 as an example

Wherein, the connecting portion 122 of the second connecting plate 12 may be provided with a third through hole, and the second end of the first connecting plate 11 is provided with a fourth through hole 113 corresponding to the area of the connecting portion 122 of the second connecting plate 12, so as to allow the second fastening member 16 to pass through the third through hole and the fourth through hole 113 to fasten the connecting portion 122 of the second connecting plate 12 and the first connecting plate 11. Illustratively, the second fastener 16 may be configured to include a bolt having an external thread at an end portion thereof and a nut adapted to the external thread of the bolt, and then the operator may previously pass the bolt through the third through-hole and the fourth through-hole 113 to fit the nut on the outer periphery of the bolt without tightening the second connecting plate 12 and the first connecting plate 11, thereby allowing the operator to rotate the second connecting plate 12 with respect to the first connecting plate 11 with the bolt as a rotation center to a desired second orientation, and tighten the bolt and the nut to clamp the first connecting plate 11 and the second connecting plate 12 after moving to the second orientation, thereby locking the first connecting plate 11 and the second connecting plate 12 in the second orientation, thereby mounting the object 20 in the desired orientation with respect to the mounting position.

In order to further increase the strength of the connection of the second connecting plate 12 and the first connecting plate 11, i.e. to further limit the possible rotation of the second connecting plate 12 in the locked condition with respect to the first connecting plate 11, the mobile bracket 10 is also provided with a second positioning pin 17, the end of which is provided with an external thread. Wherein, a second arc-shaped hole extending around the circumference of the third through hole may be provided on the connecting portion 122 of the second connecting plate 12, and a third connecting hole 114, such as a threaded hole adapted to the external thread of the second positioning pin 17, is oppositely provided on the second end of the first connecting plate 11, so that the second positioning pin 17 passes through the second arc-shaped hole to be connected to the third connecting hole 114, so as to provide additional connecting strength between the additional second connecting plate 12 and the first connecting plate 11 via the second positioning pin 17 and the third connecting hole 114.

Similar to the first arcuate aperture 112, the second arcuate aperture may be configured as a semi-circularly extending aperture to always lock with the third connecting aperture 114, i.e., with the first connecting plate 11, to ensure additional connection strength, if the second connecting plate 12 is rotated clockwise from a horizontal arrangement with respect to the first connecting plate 11, as shown in fig. 3(c) and 3(d), to a 45 degree arrangement with respect to the first connecting plate 11, as shown in fig. 3(b), or continued clockwise rotation to a vertical arrangement with respect to the first connecting plate 11, as shown in fig. 3 (a). Alternatively, the second arcuate aperture may be replaced by a plurality of positioning apertures 124, such as five positioning apertures 124, shown in fig. 1-4, arranged in circumferentially spaced relation around the third through-hole to provide the operator with an optional second orientation of a plurality, such as five, of the second connecting plates 12 relative to the first connecting plate 11, avoiding user selection difficulties.
