When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

In the related prior art, in order to meet the requirement of explosion-proof level, part of cameras can improve the explosion-proof level by increasing the wall thickness of a shell or adding a light-transmitting protective cover on the outer side of the shell, but the method can only meet the explosion-proof level of IK10 at most, namely, the shell can bear 5 impacts with energy of more than 20J, and the same point cannot be impacted for more than 4 times, and still cannot meet the explosion-proof standard with higher requirement. When the camera is impacted, the lens can move to the side far away from the ball cover to avoid the lens from being damaged, but the shell on the outer side of the lens is not moved, but the lens is exposed after the ball cover is damaged by the method, and the exposed lens is still easily damaged.

In order to solve the above problem, as shown in fig. 1 to 4, the present invention provides a camera, in which the entire inner assembly of the camera can be moved to the side away from the globe cover, so that the explosion-proof level can be ensured to exceed the IK10, and even if the globe cover is damaged, the lens is not easily damaged.

As shown in fig. 1, specifically, the camera includes a cover 1, a base 2, a movement assembly 4, and a connecting assembly 5; the base 2 and the cover body 1 are arranged in a surrounding way to form an installation space 3; the movement assembly 4 is arranged in the installation space 3, the movement assembly 4 comprises a lens 41 and a shell 42, and the lens 41 is arranged in the shell 42; the connecting assembly 5 includes an elastic member 51 disposed between the base 2 and the housing 42, and the elastic member 51 can be compressed when the movement of the core assembly 4 is toward a side close to the base 2.

As mentioned above, in some cameras in the related art, the lens is prevented from being damaged by moving the lens to a side away from the ball cover and keeping the housing outside the lens still when the camera is impacted, but this method may expose the lens after the ball cover is damaged, and the exposed lens is still easily damaged. In the camera provided by the embodiment of the present invention, the movement assembly 4 includes the housing 42 and the lens 41 disposed in the housing 42, when the camera is impacted, the housing 42 and the lens 41 can move to a side close to the base 2 at the same time, even if the cover body 1 is damaged, the housing 42 can protect the outside of the lens 41, thereby reducing the possibility of damage caused by the exposure of the lens 41 and improving the anti-riot level; moreover, when the shell 42 and the lens 41 move towards the side close to the base 2, the elastic element 51 is compressed, so that the elastic element 51 can consume part of impact energy to the movement assembly 4 when returning to the initial state, and the lens 41 can still work normally at the moment, thereby being beneficial to protecting the lens 41 and further improving the anti-riot level; meanwhile, the camera has higher explosion-proof grade, so that the safety distance between the movement assembly 4 and the cover body 1 can be reduced, the height of the whole camera is reduced, and the cost is reduced.

In the related prior art, some cameras improve the explosion-proof level by increasing the wall thickness of the shell or adding a transparent protective cover outside the shell so as to improve the overall strength of the equipment, however, the method can only meet the explosion-proof level of IK10 at most, and after light rays are refracted for many times among the multiple layers of transparent covers, light leakage may occur at the front end of the lens, which causes the problem of image blurring. And the embodiment of the utility model provides a camera can reach higher explosion-proof level to light can not take place many times refraction and lead to taking place the light leak at 41 front ends of camera lens between the multilayer translucent cover, thereby guarantees the definition of image.
