The disclosed embodiment provides a protection device, including: the base comprises a first mounting hole arranged at one end of the base and is configured to be provided with a fastener; the hinge comprises a first end and a second end hinged with the first end, and the first end is arranged on the outer wall of the first mounting hole; wherein, the axis of the hinge joint of the hinge is vertical to the gravity center line of the base.

As shown in fig. 1 and 2, the protection device provided by the embodiment of the present disclosure is fixedly installed through the first end of the hinge 20 and the outer wall of the first installation hole 101, the second end of the hinge 20 is fixedly disposed during use, and the axis passing through the hinge joint of the hinge 20 is perpendicular to the gravity center line of the base 10, so that when the base 10 falls off, the base 10 is helped to be turned over around the hinge joint of the hinge 20, and at this time, the hinge 20 is a load-bearing component, and the base 10 is pulled, thereby avoiding the direct falling of the base, causing irreparable loss, leaving processing time for users, and eliminating potential safety hazards.

The embodiment of the present disclosure takes the example that the protection device is installed on the wall, but the protection device is not limited to be installed on the wall, and the protection device may also be installed on the cabinet or other fixed objects.

The base 10 in the embodiment of the present disclosure has a plate shape, and when the base 10 is installed on a vertical or inclined wall body, "one end" of the "first installation hole 101 provided at one end of the base" may be understood as a lower end of the base 10, wherein an opening of the first installation hole 101 is close to a lowermost edge of the lower end of the base 10. Therefore, the interference phenomenon between the edge of the base and the wall body when the base is turned downwards is prevented, and the shearing force applied to the hinge is reduced as much as possible. The "one end" of the first mounting hole 101 provided at the one end of the base may be understood as an end of the base 10 that is most compressed during use when the base 10 is mounted on a lateral wall, wherein the opening of the first mounting hole 101 is close to the edge of the base 10. Therefore, the interference phenomenon between the edge of the base and the wall body when the base is turned downwards is prevented, and the shearing force applied to the hinge is reduced as much as possible.

For the sake of convenience of distinction, the fastening member disposed in the first mounting hole 101 is a first fastening member 701. The base 10 is mounted on the wall by the first fastener 701 penetrating through the first mounting hole 101.

Optionally, the first mounting hole 101 is a blind hole or a counterbore structure. In this way, it helps to hide the fasteners, keeping the base aesthetically neat.

Optionally, the outer wall of the first mounting hole 101 includes: a bottom wall 1011 which is a part of the base opposite to the opening of the first mounting hole 101; wherein the first end is disposed on the bottom wall 1011.

The first end is disposed on the bottom wall 1011 of the first mounting hole 101, the first end is disposed parallel to the bottom wall 1011 of the first mounting hole 101, and the first fastener 701 can penetrate through the bottom wall 1011 of the first mounting hole 101 and the first end of the hinge 20 to fix the base 10 and the first end of the hinge 20 on the wall. At this time, the second end of the hinge 20 may be fixed to the base 10. When the base 10 falls off, the bottom wall 1011, the first end and the first fastener 701 are left on the wall, the base 10 is fixedly connected with the second end, the base 10 and the second end turn downwards around the hinge joint of the hinge 20 under the action of gravity of the base 10, and the first end left on the wall is used as a bearing component to pull the second end and the base 10, so that the base 10 is prevented from directly falling.

Optionally, the outer wall of the first mounting hole 101 includes: a sidewall 1012 that is a partial base circumferentially disposed around the first mounting hole 101; wherein the first end is disposed on the sidewall 1012.

When the base 10 is installed on the vertical or diagonal wall 100, the sidewall 1012 provided with the first end is the bottom-most surface of the base 10; the side walls 1012 are the sides of the base 10 that are most compressed when the base 10 is installed in a transverse wall. The second end can be separately disposed on the wall, wherein the second end can be located between the base 10 and the installation surface of the wall 100, or around the base 10. When the base 10 falls off, under the action of gravity of the base 10, the base 10 and the first end turn downward in the axial direction by using the hinge joint of the hinge 20, and the second end is a bearing component, so that the first end and the base 10 connected with the first end are pulled, and the base 10 is prevented from directly falling.

In addition, the second end and the bottom wall 1011 of the first mounting hole 101 can be disposed on the wall together by the first fastener 701. When the base 10 falls off, the bottom wall 1011, the second end and the first fastener 701 are left on the wall, the base 10 is fixedly connected with the first end, the base 10 and the first end turn downwards around the hinge joint of the hinge 20 under the action of gravity of the base 10, and the second end left on the wall is used as a bearing component to pull the first end and the base 10, so that the base 10 is prevented from directly falling.

Optionally, the base 10 further comprises: and a second mounting hole 102 provided to the base 10, configured to provide a fastener.

For the sake of convenience of distinction, the fastener disposed in the second mounting hole 102 is herein the second fastener 702.

The base 10 is installed on the wall body by the second fastening member 702 penetrating the second installation hole 102. The second mounting hole 102 is a blind hole or a counter bore, and the "counter bore" is a stepped hole. The second fastening piece 702 is partially embedded in the wall body, and the other part of the second fastening piece is hidden in the second mounting hole 102, so that the smoothness of the base 10 is ensured, and the second fastening piece 702 is prevented from protruding out of the surface of the base 10 and scratching other people; secondly, the second fastening member 702 is located in the second mounting hole 102, and if the surface of the second fastening member 702 contacts the inner surface of the second mounting hole 102, the second fastening member 702 can also play a certain role in supporting and bearing weight.

Alternatively, the opening of the first mounting hole 101 and the opening of the second mounting hole 102 are located at the same end of the base 10. Wherein, the first mounting hole 101 and the second mounting hole 102 are located at the same end of the base 10, and the vertical distance from the opening of the first mounting hole 101 to the end edge of the base 10 is smaller than the vertical distance from the opening of the second mounting hole 102 to the end edge of the base 10.

For example, the first end of the hinge 20 is disposed on the bottom wall 1011 of the first mounting hole 101, and the second end is disposed on the base 10, when the second fastener 702 in the second mounting hole 102 fails, the base 10 falls, the base 10 turns downward with the hinge of the hinge 20 as an axis, the first end of the hinge 20 becomes a load-bearing member, and under the action of the pulling force, the second ends of the base 10 and the hinge 20 are suspended in the air, so as to effectively prevent the base 10 from falling and injuring others.

If the vertical distance from the opening of the first mounting hole 101 to the end edge of the base 10 is greater than or equal to the vertical distance from the opening of the second mounting hole 102 to the end edge of the base 10, before the second fastening member 702 of the second mounting hole 102 fails, the first end of the hinge 20 is a load-bearing member, and because the second fastening member 702 does not fail, the base 10 cannot be turned over, and a user cannot judge the failure sequence of the first fastening member 701 and the second fastening member 702, so that the safety hazard still exists in the arrangement that the vertical distance from the opening of the first mounting hole 101 to the end edge of the base 10 is greater than or equal to the vertical distance from the opening of the second mounting hole 102 to the end edge of the base 10, and the purpose of preventing the base 10 from directly falling cannot be achieved.

As used herein, "fastener failure" means that the fastener breaks, completely loses its intended function, and is incapable of further use.

Alternatively, the opening of the first mounting hole 101 and the opening of the second mounting hole 102 are located at both ends of the base 10. When the base 10 is installed on a vertical or oblique wall, the opening of the second installation hole 102 is located at the upper end of the base 10, and the opening of the first installation hole 101 is located at the lower end of the base 10. Thus, second fastener 702 in second mounting hole 102 is subject to tensile and shear forces, and the fastener in first mounting hole 101 is subject to compressive and shear forces, with second fastener 702 failing prior to first fastener 701. Thus, when the second fastening member 702 in the second mounting hole 102 fails, the base 10 is turned downwards with the hinge joint of the hinge 20 as the axis, the first end or the second end of the hinge 20 is the bearing component, and the base 10 is suspended in the air under the pulling force of the hinge 20, so as to avoid safety accidents caused by direct falling and wait for the user to handle.

Here, "the opening of the first mounting hole 101 and the opening of the second mounting hole 102 are located at both ends of the base 10, respectively," it can be understood that: the first mounting hole 101 is disposed opposite to the second mounting hole 102.

Optionally, the fastener comprises a screw and/or a bolt. Thus, the base 10 is convenient to mount, fix and dismount, and can be mounted quickly, conveniently and quickly when in use.

Optionally, the screw is an expansion screw. In this way, the mounting of the base 10 can be made more stable.

Optionally, the bolt is an expansion bolt. In this way, the mounting of the base 10 can be made more stable.

The embodiment of the present disclosure provides a suspension bracket, which includes a cantilever 30 and a protection device as described above, wherein the cantilever 30 is fixedly connected to a base 10 of the protection device.

By adopting the embodiment, the potential safety hazard of the suspension bracket can be eliminated and the safety is improved in the using process of the suspension bracket.

Optionally, the suspension support further comprises a safety line, one end of which is arranged at the cantilever 30 or the base 10.

The other end of the safety rope can be arranged on the wall 100 or on other fixing parts, so that the cantilever 30 or the base 10 is pulled by the safety rope in the falling process of the cantilever 30 or the base 10, and the safety rope and the protection device play a role in double protection. When the protective device can not work normally, the safety rope can play a role, and irreparable loss is avoided.

The embodiment of the present disclosure provides a projection device, which includes a projector 40 and a suspension bracket as described above, where the projector 40 is disposed on the suspension bracket.

Optionally, one end of the cantilever is fixedly connected with the base, and the other end of the cantilever is detachably connected with the projector. The cantilever and the projector can be directly connected through a fastener or indirectly connected with the projector through a connecting piece. The connecting piece can be a hand grip, the projector is fixed through the hand grip, and then the hand grip is connected with the cantilever.

By adopting the embodiment, the use safety of the projection equipment is improved, and the worry of a user can be effectively relieved.

Optionally, the projection device further comprises: and a buffer layer 50 disposed on an outer sidewall of the projector 40. The buffer layer is arranged on one side, close to the wall body, of the projector. When the projector falls and turns over, the position of the buffer layer is the position where the projector firstly collides with the wall. Like this, when projector 40 takes place to fall, through buffer layer 50 can effectual reduction projector 40's damage degree, or, when base 10 drops and overturns downwards, projector 40 uses hinge 20's articulated department as the original point, when parts such as the downwards upset swing to wall body 100 or the cabinet body, can effectually alleviate projector 40 and wall body 100 or the collision dynamics of the cabinet body, and then reduce projector 40's damage degree.
