Abstract

The invention provides a back focus adjusting mechanism and a gun type camera applying the same. The back focus adjusting mechanism comprises a driving motor, a reduction gear set and a positioning guide assembly. The positioning guide assembly comprises a mounting plate, a fixing plate and a guide assembly, the guide assembly is mounted on the mounting plate, and the mounting plate is connected with the fixing plate; The guide assembly comprises a guide rod, a transmission screw rod and a guide seat fixedly connected with the mounting plate; a central hole for inserting the guide rod is formed in the guide seat; A threaded hole for inserting one end of the transmission screw is formed in the guide rod, the other end of the transmission screw is connected with an output gear of the reduction gear set, and the output gear of the reduction gear set drives the transmission screw to rotate coaxially; The driving motor is connected with the reduction gear set, the reduction gear set drivesthe transmission screw to rotate to drive the guide rod to move, and the guide rod penetrates through the fixing plate to push the mounting plate. The back focus adjusting mechanism provided by the invention has a simpler guide structure under the condition of meeting the requirement of pushing the fixing plate.

Description

technical field [0001] The invention belongs to the technical field of cameras, and relates to a back focus adjustment mechanism, in particular to a back focus adjustment mechanism and a bullet camera for which the same is applied. Background technique [0002] In the prior art, the distance between the lens and the sensor is generally changed by adjusting the position of the lens. Its focusing mechanism is set on the lens, generally in a cylindrical shape, through manual adjustment or software control to achieve the purpose of focusing, that is, front focus adjustment. With the needs of security, for bullet cameras, the accuracy of manual focusing is difficult to be accurate, and at the same time increases the focusing time, which is not convenient for shooting, and the cost increases by 200%-500%, which is not conducive to production and promotion, while software-controlled focusing will be mainstream. [0003] In order to solve the above problems, in the prior art, the ...
