Description

Technical Field

[0001] The invention relates to the technical field related to cameras, in particular to an infrared night-vision security camera. Background Art

[0002] Infrared night vision cameras are mainly used in dark environments with no visible light or dim light. They use infrared transmitting devices to actively project infrared light onto objects. After being reflected by the object, the infrared light enters the lens for imaging, which can play a security role in the dark night.

[0003] However, in actual use, the camera is very likely to be damaged by intruders, making it impossible for the camera to capture the intruder's actions. Usually, the camera is prevented from working properly by cutting the power line or directly damaging the lens.

DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0041] Example: Figure 1-5 and Fig.10 As shown, an infrared night vision security camera of the present invention comprises a mounting shell 1, one end of the mounting shell 1 is provided with a packaging end cover 11, the other end thereof is provided with a lens cover 12, the bottom thereof is also provided with a transmission cable 13, and the packaging end cover 11 is provided with an opening capable of allowing a wire to pass through;

[0042] A disguised cable 3 disguised as a transmission cable 13, wherein one end of the disguised cable 3 is provided with a threaded joint 31;

[0043] A wire break detector 2 for detecting wire breakage of a camouflaged cable 3, the wire break detector 2 comprising a support tube 21 mounted on one side of the package end cover 11 via a mounting substrate 23, a T-shaped transmission member that can be connected to a threaded joint 31, and a screw-insertion assembly 27 for locking the T-shaped transmission member, a detection assembly is arranged inside the support tube 21, and four cross-through cavities 211 distributed in an annular shape are also opened at one end thereof;

[0044] The fixer 6 is sleeved on the other end of the camouflaged cable 3, and the fixer 6 is composed of an open base 61 for accommodating the camouflaged cable 3, a fixing cylinder 62 connected to one end of the open base 61, and a T-shaped rotating body 63 screwed to the fixing cylinder 62. The fixing cylinder 62 is provided with an elastic tightening member 64 used in conjunction with the T-shaped rotating body 63 to fix the camouflaged cable 3.

[0045] Specifically, the transmission cable 13 is hidden by the camera bracket 001 , and the transmission cable 13 is protected by the camera bracket 001 . The specific structure and installation method of the camera bracket 001 are not limited herein.

[0046] Among them, Figure 5 As shown, the detection assembly consists of a detection plate 26 slidably arranged in a support tube 21, a detection spring 24 installed on one side of the detection plate 26, and a detection spring 25 installed on the other side of the detection plate 26. A detector 22 for wire break detection is also provided on one side of the detection plate 26, and the detection spring 24 is located on the outside of the detector 22.

[0047] Specifically, the detector 22 can be a speed sensor or an acceleration sensor installed on the detection board 26, which can determine whether the line is broken by measuring the speed or acceleration of the detection board 26. It can also be a distance sensor installed on the mounting substrate 23, which can determine whether the line is broken by measuring the distance between the detection board 26 and the mounting substrate 23.

[0048] After the T-shaped transmission part is connected to the threaded joint 31, the camouflaged cable 3 is pulled to move the T-shaped transmission part out of the support tube 21, and the detection plate 26 is driven by the T-shaped transmission part to make the detection spring 1 24 in a stretched state and the detection spring 25 in a compressed state. After the camouflaged cable 3 is cut off, the detection plate 26 is driven due to the elastic force of the detection spring 1 24 and the detection spring 25, so that the broken wire detection can be achieved by measuring the speed change of the detection plate 26 or measuring the distance from the detection plate 26 to the mounting substrate 23.

[0049] Among them, Figure 5 and Figure 8 As shown, the T-shaped transmission member includes a sliding body 28 installed on the other side of the detection plate 26, one end of the sliding body 28 is provided with a limiting body 29 that slides with the support tube 21, one side of the limiting body 29 is provided with a threaded blind hole 291 that extends into the sliding body 28 and can be threaded with the threaded joint 31, and four annular plug holes 292 are also provided on its outer wall, and four annular sliding protrusions 281 are provided on the outer wall of the sliding body 28. A threaded connection is adopted between the T-shaped transmission member and the threaded joint 31, so that the camouflaged cable 3 can be easily replaced, which is beneficial to replace the camouflaged cable 3 that has been cut; the T-shaped transmission member is used in conjunction with the annular convex edge 212 to limit the detection plate 26, and can effectively avoid damage to the detector 22 caused by collision with the detection plate 26 or the mounting substrate 23.

[0050] Among them, Figure 4-6As shown, the screw-in assembly 27 includes an anti-skid sleeve 271 which is sleeved on the outside of the support tube 21 and screwed with the external thread section on the support tube 21, a limit stop cover 272 screwed on one end of the anti-skid sleeve 271, and a limit plate 274 slidably arranged in the cross cavity 211. One end of the internal thread section on the anti-skid sleeve 271 is provided with an inner conical surface 276, and the center hole of the limit plate 274 is provided with a movable plug rod 273 for plugging with the plug hole 292. The movable plug rod 273 is slidably matched with the cross cavity 211, and one end of the movable plug rod 273 is formed by cutting to form an inclined surface abutting against the inner conical surface 276, and the other end of the movable plug rod is also sleeved with a matching spring 275 abutting against the limit plate 274 and the cross cavity 211. The limit stop cover 272 is threadedly connected to the anti-skid sleeve 271, and adopts a split design to facilitate later maintenance.

[0051] Specifically, the limit stop cover 272 is provided with an avoidance hole that allows the limit body 29 to pass through. The setting of the avoidance hole ensures that the limit stop cover 272 will not hinder the movement of the T-shaped transmission member; the limit stop cover 272 is also provided with anti-slip grooves on the outer wall. The anti-slip grooves can increase the friction between the hand and facilitate the limit stop cover 272 to be unscrewed from the anti-slip sleeve 271.

[0052] The anti-slip sleeve 271 is rotated. Since the anti-slip sleeve 271 is threadedly connected to the support tube 21, the anti-slip sleeve 271 will rotate and move at the same time. The inner conical surface 276 and the upper inclined surface of the movable plug rod 273 are pressed together to make the movable plug rod 273 inserted into the plug hole 292 to fix the T-shaped transmission part. At the same time, the matching spring 275 is squeezed by the limit plate 274. When the camouflage cable 3 needs to be pulled, the anti-slip sleeve 271 is rotated in the opposite direction, and the elastic force of the matching spring 275 is used to make the movable plug rod 273 disengage from the plug hole 292.

[0053] Among them, Figure 7 As shown, an annular protrusion 212 that slides with the sliding body 28 is provided on the inner wall of the support tube 21, and a guide groove 213 that slides with the sliding protrusion 281 is opened on the annular protrusion 212, and one side of the annular protrusion 212 is connected to the detection spring 25. The sliding protrusion 281 and the guide groove 213 are used to guide and limit the sliding body 28 to prevent the sliding body 28 from shaking, vibrating, etc., which causes the plug-in hole 292 to be unable to align with the movable plug rod 273.

[0054] Among them, Figure 5As shown, an annular buffer pad 231 is installed on one side of the mounting substrate 23 for supporting the detection spring 24 and preventing the detector 22 from colliding with the mounting substrate 23. The annular buffer pad 231 is located in the support tube 21. In addition to being connected to the detection spring 24, the annular buffer pad 231 also plays a limiting role, which can prevent the detector 22 from colliding with the mounting substrate 23. When the detection plate 26 collides with the annular buffer pad 231, the annular buffer pad 231 provides buffering, which can reduce the probability of the detector 22 being damaged due to impact.

[0055] Specifically, a through hole coaxial with the support tube 21 is provided on the mounting substrate 23 , and the provision of the through hole facilitates the wiring operation between the detector 22 and the control module 4 .

[0056] Among them, Fig. 9 and Fig.10 As shown, the T-shaped rotating body 63 is provided with a through hole 632 for allowing the disguised cable 3 to pass through, and one end of the through hole 632 is provided with an inner cone 631. The through hole 632 enables the disguised cable 3 to pass through the T-shaped rotating body 63.

[0057] Specifically, the elastic tightening member 64 includes a mounting portion 641 for connecting to the fixed tube 62, one end of the mounting portion 641 is provided with a plurality of arc connecting portions 642 distributed in a ring shape, and the end of the arc connecting portion 642 away from the mounting portion 641 is provided with a matching conical surface 643 matching with the second inner conical surface 631.

[0058] After the camouflaged cable 3 passes through the open base 61, the camouflaged cable 3 is straightened and the T-shaped rotating body 63 is rotated. Since the T-shaped rotating body 63 is threadedly connected to the fixed tube 62, the T-shaped rotating body 63 will rotate and move at the same time, and the arc-shaped connecting part 642 is driven by the pressure cooperation between the second inner conical surface 631 and the matching conical surface 643 to tighten or open the elastic tightening member 64. The elastic tightening member 64 is used to clamp the camouflaged cable 3, which is suitable for fixing camouflaged cables 3 of different thicknesses. The excess camouflaged cables 3 can be directly cut off or stored using the open base 61, and then the open base 61 is fixed to the wall or the support bracket with screws to complete the installation of the fixer 6.

[0059] Among them, Figure 1-3 As shown, two supporting brackets 14 arranged face to face are provided in the installation shell 1, and a battery 5 is provided between the two supporting brackets 14. A camera is also provided at one end of the battery 5. A threading hole for accommodating the passage of wires is also opened on the supporting bracket 14. The existence of the threading hole is conducive to the wiring of the camera and the control module 4; the battery 5 is used as a backup power supply, so that the camera can continue to perform monitoring work when the external power supply is lost due to power outages, malicious power outages, etc.

[0060] Among them, Figure 1-3 As shown, a control module 4 capable of remotely communicating with a monitoring and control terminal is installed in the packaging end cover 11. The control module 4 is electrically connected to the battery 5, the detector 22 and the camera through wires, respectively. The control module 4 also includes a communication unit and an alarm unit capable of communicating with the monitoring and control terminal. The alarm unit can alert people around or warn of destructive behavior of intruders by sounding an alarm; the signal collected by the detector 22 is sent to the control module 4, and after processing and analysis, it is determined whether the line is broken by judging the speed change and position change of the detection board 26. If it is determined that the line is broken, the control module 4 sends a signal to the monitoring and control terminal through the communication unit, and uses the alarm system of the monitoring and control terminal to remind the on-duty personnel in the monitoring room.

[0061] During operation, the transmission cable 13 is hidden by using the camera bracket 001, the anti-slip sleeve 271 is rotated, and the inner conical surface 276 is used to press and cooperate with the inclined surface on the movable plug rod 273 to insert the movable plug rod 273 into the plug hole 292 to fix the T-shaped transmission member. Then, a camouflaged cable 3 is taken, and one end of the camouflaged cable 3 is fixed by screwing the threaded connector 31 into the threaded blind hole 291 on the T-shaped transmission member. After the other end of the camouflaged cable 3 passes through the open base 61, the installation position of the fixer 6 is determined, and then the anti-slip sleeve 271 is rotated in the opposite direction. When the movable plug rod 273 is completely disengaged, the fixing position of the fixing device 6 is determined. After the plug-in hole 292 is inserted, the camouflaged cable 3 is straightened so that the T-shaped transmission member can be moved out of the support tube 21, and the detection plate 26 is driven by the T-shaped transmission member until the camouflaged cable 3 cannot be pulled, and the T-shaped rotating body 63 is rotated, and the other end of the camouflaged cable 3 is fixed by tightening the elastic tightening member 64, and then the fixer 6 is fixed to the wall or the support bracket with screws. After the intruder cuts the camouflaged cable 3 as a transmission cable 13, the change is detected by the detector 22, and a signal is sent to the monitoring control end with the help of the control module 4, and the alarm system of the monitoring control end is used to remind the on-duty personnel in the monitoring room.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
