Description

Technical Field

[0001] The invention relates to an industrial lens, in particular to an industrial lens protection component for video monitoring. Background Art

[0002] Industrial lenses are optical lenses specially used in industrial applications. They have high resolution, high contrast and high optical performance to meet the needs of the industrial field for image acquisition. Due to their precision and high cost, they will be damaged and cause losses when encountering external force collision. The existing ones are equipped with a protective shell and an elastic buffer structure. In this way, even a slight vibration during use will cause the lens to shake, affecting the imaging effect. In view of the above problems, it is necessary to design a protective structure that can solve both the shaking problem and the damage reduction problem.

[0003] Therefore, existing industrial lenses need to be further improved. Summary of the invention

[0004] The purpose of the present invention is to provide an industrial lens protection component for video surveillance, which can achieve a buffering effect on the lens when it collides and prevent slight shaking during normal use.

[0005] In order to achieve the above object, the present invention adopts the following scheme:

[0006] An industrial lens protection component for video surveillance, comprising a protective shell, an industrial lens installed in the protective shell, a plurality of buffer devices arranged on the protective shell, a swing clamping device arranged between the buffer device and the protective shell, a stabilization control device for maintaining the stability of the plurality of swing clamping devices arranged on the protective shell, a multi-radial channel structure arranged on the protective shell, a pressing gravity ball for unlocking the stabilization control device arranged at the center of the multi-radial channel structure, a centering device for controlling the centering of the pressing gravity ball arranged on the protective shell, and an outer control adjustment ring assembly capable of controlling the reset of the stabilization control device and the reset of the centering device arranged on the protective shell;

[0007] When the clamping gravity ball encounters external force, it can move radially along one of the channels in the multi-radial channel structure. At this time, the stability control device moves axially to unlock the activities of the swing clamping device and multiple swing clamping devices.

[0008] Furthermore, the protective shell comprises a shell, an opening is arranged at the front of the shell, a protective lens is arranged at the opening, and a back plate is arranged at the rear end of the shell.

[0009] Furthermore, a plurality of the buffer devices are evenly distributed around the circumference of the central axis of the housing;

[0010] The buffer device comprises a telescopic sleeve arranged on the protective shell, a telescopic shaft body is movably arranged in the telescopic sleeve, and an elastic buffer structure for keeping the telescopic shaft body pressed inward is arranged between the telescopic shaft body and the telescopic sleeve.

[0011] Furthermore, the swing clamping device includes an annular positioning groove arranged on the outer wall of the industrial lens, and the inner end of the telescopic shaft body is hinged with a clamping arc plate, and the clamping arc plate is clamped on the outer wall of the annular positioning groove. Multiple clamping arc plates clamp the industrial lens and center the industrial lens on the central axis of the protective shell, and a hinge structure is arranged between the clamping arc plate and a corresponding telescopic shaft body.

[0012] Furthermore, the stability control device includes a positioning pin hole arranged on the end surface of the clamping arc plate, a middle plate is arranged in the protective shell, a positioning pin extending to the outside of the middle plate is movably arranged in the positioning pin hole, a connecting annular seat is arranged between the outer ends of multiple positioning pins, an elastic structure for pressing and disengaging the positioning pin from the positioning pin hole is arranged between the middle plate and the connecting annular seat, and a top pressing shaft for pressing the pressing gravity ball is arranged on the connecting annular seat.

[0013] Furthermore, when the compression gravity ball is subjected to external impact force or gravitational potential energy of falling, it will enter the multi-radial channel structure along the radial direction of the protective shell. At this time, the top pressure shaft loses support and moves axially under the action of the elastic structure, thereby causing the locating pin to disengage from the locating pin hole. At this time, the multiple buffer devices are free to move and buffer the impact of external forces on the industrial lens.

[0014] Furthermore, the multi-radial channel structure includes an outer control seat arranged on the outer side of the middle plate, and a plurality of radial channels are evenly distributed on the outer control seat around the central circumference of the outer control seat, and the clamping gravity ball is arranged at the center position between the plurality of radial channels.

[0015] Furthermore, the centering device includes a gravity ball reset push rod movably arranged in the radial channel, an annular guide groove is arranged on the outer control seat, a plurality of arc-shaped reset parts are movably arranged in the annular guide groove, a first hinge seat is arranged on the arc-shaped reset part, a second hinge seat is arranged on the gravity ball reset push rod, a reset connecting rod is hinged between the first hinge seat and the second hinge seat, a plurality of reset spring assemblies for keeping the gravity ball reset push rod away from the compression gravity ball at the center are arranged in the annular guide groove, and an inner adjustment ring is arranged between the plurality of arc-shaped reset parts.

[0016] Further, the outer control adjustment ring assembly comprises an axial synchronization annular groove arranged on the circumferential outer wall of the connecting annular seat, a synchronization ring is installed in the axial synchronization annular groove, and the outer wall of the synchronization ring is connected to the outer adjustment ring through a plurality of fixing rods;

[0017] The outer adjusting ring is sleeved on the inner adjusting ring, a plurality of synchronous grooves are arranged on the inner adjusting ring, a plurality of synchronous blocks are arranged on the inner wall of the outer adjusting ring, and the synchronous block is correspondingly installed in one of the synchronous grooves.

[0018] Furthermore, when the outer adjustment ring is axially adjusted, the synchronization ring will drive the axial synchronization annular groove to perform synchronous axial movement, thereby driving the top pressure shaft in the middle to perform axial movement;

[0019] When the outer adjusting ring rotates, the inner adjusting ring will rotate synchronously through the cooperation between the synchronous block and the synchronous groove.

[0020] In summary, the present invention has the following beneficial effects compared with the prior art:

[0021] The present invention solves the shortcomings of existing industrial lenses. Through the structural setting of the present invention, it has the following advantages: the present invention has an outer protective shell structure of the industrial lens, which can avoid damage to the industrial lens caused by the outside. At the same time, a multi-directional buffer structure is arranged between the outer shell and the lens to further buffer the impact forces of multiple directions from the outside. Due to the existence of the elastic buffer mechanism, in order to avoid the shaking of the lens caused by tiny vibrations during daily use, a stabilization control device is arranged to maintain the stability of the lens during imaging and block the buffer structure. When an external force collision or drop occurs, the pressing gravity ball will shift and unlock the stabilization control device. Under the unlocking restriction of the stabilization control device, the buffer mechanism can move freely to provide buffer protection for the lens. When reinstallation is required, it only needs to adjust the external control adjustment ring assembly to complete the resetting of the stabilization control device and the pressing gravity ball. The operation is simpler and more convenient, which improves the protection effect and use stability of the lens. BRIEF DESCRIPTION OF THE DRAWINGS
