Description

Technical Field

[0001] The invention relates to an industrial lens, and 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 industrial field's needs for image acquisition. Due to their precision and high cost, they can be damaged and cause losses when encountering external force collisions. The existing ones are equipped with a protective shell and an elastic buffer structure. In this way, even slight vibrations during use will cause the lens to shake, affecting the imaging effect. To address the above problems, it is necessary to design a protective structure that can not only solve the shaking problem but also reduce the damage 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 during collision 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 includes a protective housing, an industrial lens mounted within the protective housing, a plurality of buffer devices disposed on the protective housing, a swing clamping device disposed between the buffer devices and the protective housing, a stabilization control device disposed on the protective housing for maintaining the stability of the plurality of swing clamping devices, a multi-radial channel structure disposed on the protective housing, a compression gravity ball disposed at the center of the multi-radial channel structure for unlocking the stabilization control device, a centering device disposed on the protective housing for controlling the centering of the compression gravity ball, and an outer control adjustment ring assembly disposed on the protective housing capable of controlling the resetting of the stabilization control device and the centering device;

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

[0008] Furthermore, the protective shell includes a shell, an opening is provided at the front of the shell, a protective lens is provided at the opening, and a back plate is provided 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 includes 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 stabilization control device includes a positioning pin hole arranged on the end face 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 pressure shaft for pressing the pressing gravity ball is provided 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 its support and moves axially under the action of the elastic structure, thereby causing the positioning pin to disengage from the positioning 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 outside 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 provided 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 provided on the arc-shaped reset part, a second hinge seat is provided 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 center of the compression gravity ball are provided in the annular guide groove, and an inner adjustment ring is provided between the plurality of arc-shaped reset parts.

[0016] Furthermore, the outer control adjustment ring assembly includes an axial synchronization annular groove provided 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 via a plurality of fixing rods;

[0017] The outer adjustment ring is sleeved on the inner adjustment ring. The inner adjustment ring is provided with a plurality of synchronization grooves. The inner wall of the outer adjustment ring is provided with a plurality of synchronization blocks. The synchronization block is correspondingly installed in one of the synchronization grooves.

[0018] Furthermore, when the outer adjustment ring is axially adjusted, the synchronization ring drives the axial synchronization annular groove to perform synchronous axial movement, thereby driving the pressing 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 synchronizing block and the synchronizing groove.

[0020] In summary, the present invention has the following beneficial effects compared to 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 for 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 external impact forces in multiple directions; due to the existence of the elastic buffer mechanism, in order to avoid the shaking of the lens caused by small vibrations during daily use, a stabilization control device is provided 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 be offset and the stabilization control device will be unlocked. Under the unlocking limit of the stabilization control device, the buffer mechanism can move freely to provide buffering protection for the lens. When reinstallation is required, it is only necessary to adjust the external control adjustment ring assembly to complete the reset of the stabilization control device and the reset of the pressing gravity ball. The operation is simpler and more convenient, which improves the protection effect and stability of the lens. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the stabilization control device 5 moves axially to unlock the movement of the swing clamping device 4 and the plurality of swing clamping devices 4.

[0034] When the industrial lens 2 is in use, it is installed in the protective housing 1 to protect the industrial lens 2;

[0035] Due to the complex installation and use environment, the protective housing 1 can reduce the damage to the industrial lens 2. The protective housing 1 is installed at the location where imaging is required.

[0037] When an external collision or impact occurs, the internal pressing gravity ball 7 will move in one of the directions due to the external force and enter one of the channels in the multi-radial channel structure 6. At this time, the pressing gravity ball 7 will break away from the stabilizing control device 5, and the stabilizing control device 5 will pop out, unlocking the swing clamping device 4 and the buffer device 3.

[0038] The plurality of buffer devices 3 can buffer the internal industrial lens 2, reducing damage to the industrial lens 2 caused by external forces;
