[0002] Explosion-proof cameras belong to the category of explosion-proof monitoring products. They are the intersection of the explosion-proof industry and the monitoring industry. Because conventional camera products cannot be used in high-risk flammable and explosive scenes, products with explosion-proof functions and relevant certificates issued by national authoritative agencies can be called explosion-proof cameras.

[0003] For example, a positive pressure explosion-proof camera with Chinese patent publication number CN213880004U includes a base, a shell, a camera body, a glass plate, an insert plate and a wind curtain head; the shell is fixed to the upper end of the base; the camera body is fixed in the shell; the glass plate is fixed to the front end of the shell; the insert plate is fixed to the rear end of the shell so as to be slidable up and down; an air inlet duct is provided at the rear section of the right side wall of the shell; an air outlet and a wind curtain outlet are provided at the front section of the upper end of the shell; the air outlet is connected to the interior of the shell.

[0004] The explosion-proof camera in the above patent can only prevent water vapor condensation when in use. However, when the existing explosion-proof camera is in use, since the camera is installed inside the factory, there are often large trucks driving inside the factory, and most explosion-proof cameras are positioned with bolts, making it impossible to rotate. When the large truck comes into contact with the explosion-proof camera, it may squeeze the camera and cause it to deviate and break. Therefore, a device is needed to improve the above problem. Utility Model Content

[0007] Preferably, the support device includes a support rear plate, a connecting rib plate and a support base, the connecting rib plate is symmetrically fixed to the mounting plates at both ends of the support base, and the support rear plate is fixedly mounted on the rear end bottom of the support base.

[0008] Preferably, the positioning device includes an explosion-proof camera, a vertical support rod, a base, a protective cover and a circular wheel, the circular wheel is symmetrically rotatably installed on both sides of the inner side of the protective cover, the protective cover is fixedly installed on the front end outer ring of the explosion-proof camera, the explosion-proof camera is fixedly installed on the top end of the base, and the vertical support rod is fixedly installed on the bottom rear end of the base.

[0010] Preferably, the vertical support rod is located between the two T-shaped push plates.

[0011] Preferably, a plastic layer is fixedly mounted on the outer ring of the circular wheel.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the device is in use, when the truck contacts the protective cover, the explosion-proof camera can be squeezed to rotate and deviate. At the same time, the base rotates on the support base, so that the explosion-proof camera can be prevented from breaking. The vertical support rod contacts the T-shaped push plate, and the reset spring can provide a buffering force, so that when the explosion-proof camera is subjected to squeezing force, the reset spring can drive the explosion-proof camera to reset again, completing the work of quickly rotating and resetting the explosion-proof camera after being hit.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 , the utility model provides an embodiment: an explosion-proof camera with elastic protection function, including a supporting device 2, a limiting device 1 is fixedly installed on the rear ends of both sides of the supporting device 2, a positioning device 3 is rotatably installed on the top of the supporting device 2, the limiting device 1 includes a reset spring 4, a T-shaped push plate 5, a lateral displacement plate 6, an anti-slip sheet 7, a round rod 8 and a supporting cavity 9, the round rod 8 is symmetrically fixedly installed at the inner side end of the supporting cavity 9, the anti-slip sheet 7 is fixedly installed at one end of the round rod 8, the lateral displacement plate 6 is slidably sleeved on the round rod 8, the T-shaped push plate 5 is fixedly installed on the top of the side end of the lateral displacement plate 6 away from the round rod 8, and the reset spring 4 is symmetrically fixedly installed between the support cavity 9 and the lateral displacement plate 6.

[0021] The supporting device 2 includes a supporting rear plate 10, a connecting rib plate 11 and a supporting base 12. The connecting rib plate 11 is symmetrically fixed to the two ends of the supporting base 12. The supporting rear plate 10 is fixedly installed at the rear end bottom of the supporting base 12 and is fixedly connected between the supporting base 12 and the supporting cavity 9 through the connecting rib plate 11, so that the connection stability between the supporting cavity 9 and the supporting base 12 can be improved.

[0022] The positioning device 3 includes an explosion-proof camera 13, a vertical support rod 14, a base 15, a protective cover 16 and a circular wheel 17. The circular wheel 17 is symmetrically rotatably installed on both sides of the inner part of the protective cover 16. The protective cover 16 is fixedly installed on the front outer ring of the explosion-proof camera 13. The explosion-proof camera 13 is fixedly installed on the top of the base 15. The vertical support rod 14 is fixedly installed on the bottom rear end of the base 15 and is rotatably installed on both sides of the inner part of the protective cover 16 by the circular wheel 17, so that excessive friction of the protective cover 16 can be prevented.

[0023] The base 15 is rotatably mounted on the top center of the support base 12 , and the support cavity 9 is fixedly mounted on both sides of the support rear plate 10 , which can support the support cavity 9 to work.

[0024] The vertical support rod 14 is located between the two T-shaped push plates 5 . When the vertical support rod 14 rotates left and right, it can drive the T-shaped push plates 5 to move toward the inside of the support cavity 9 .

[0025] A plastic layer is fixedly mounted on the outer ring of the circular wheel 17 to prevent the circular wheel 17 from colliding with the outside world.

[0026] Working principle: When in use, the support base 12 is first fixedly installed on the external wall. When the external truck turns and contacts the explosion-proof camera 13, it will first contact the protective outer cover 16. The setting of the protective outer cover 16 can prevent the truck from directly contacting the surface of the explosion-proof camera 13, thereby avoiding damage to the explosion-proof camera 13. At the same time, the round wheels 17 are rotatably installed on both sides of the inner side of the protective outer cover 16, so that excessive friction between the protective outer cover 16 and the truck can be prevented, thereby improving the service life of the protective outer cover 16. Afterwards, when the explosion-proof camera 13 is squeezed and rotated by the truck, the explosion-proof camera 13 can be rotated on the top of the support base 12 with the bottom center of the base 15 as the base point. At this time, when the base 15 rotates, it can drive the vertical support rod 14 to contact the T-shaped push plate 5, thereby squeezing the T-shaped push plate 5 to drive the lateral displacement plate 6 to move toward the inside of the support cavity 9. At this time, the lateral displacement plate 6 is slidably sleeved on the round rod 8, and the round rod 8 is located at the support The interior of the support cavity 9 ensures that the lateral displacement plate 6 moves straightly toward the interior of the support cavity 9. Subsequently, when the truck loses contact with the protective outer cover 16, the elasticity of the return spring 4 will drive the lateral displacement plate 6 to move outward and reset. At this time, the T-shaped push plate 5 is always in contact with the vertical support rod 14, so that the T-shaped push plate 5 can squeeze the vertical support rod 14 to move and reset. Until the lateral displacement plate 6 moves outward to the limit position, the T-shaped push plate 5 can squeeze the vertical support rod 14 to drive the explosion-proof camera 13 to reset again, so that the explosion-proof camera 13 can perform video recording of the designated location again. Through the return spring 4, T-shaped push plate 5, lateral displacement plate 6, anti-slip sheet 7, round rod 8 and support cavity 9, one is set at each end of the supporting rear plate 10, so that the explosion-proof camera 13 can be reset by the return spring 4 after rotating left or right, and the anti-slip sheet 7 can be set to prevent the lateral displacement plate 6 from sliding off the round rod 8, thereby completing the rapid reset of the explosion-proof camera 13.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
