[0001] This utility model relates to the field of laboratory safety technology, specifically to a roving security camera. Background Technology

[0002] A patrol-type security camera is a monitoring device with automatic patrol function. It can automatically switch monitoring areas according to preset paths and time intervals to achieve all-round, blind-spot-free monitoring coverage.

[0003] Chinese Patent Publication No. CN216079171U discloses a roving laboratory safety monitoring device, including a slide rail installed on the top of the laboratory. A monitoring device is slidably connected within the slide rail, and a traction mechanism is installed at the top of the slide rail to drive the monitoring device to reciprocate along the length of the slide rail. The monitoring device includes a housing, a swing mechanism, and a camera. The swing mechanism is installed inside the housing and drives the camera to swing along the width of the slide rail. This device can monitor the entire laboratory in a roving manner using only one camera, and its automatic swing during the roving process greatly increases the monitoring range.

[0004] The aforementioned prior art can drive the monitoring device to move back and forth along the slide to achieve roving monitoring of the laboratory area. However, the monitoring device can only move within the range of the slide, and the length of the slide cannot be adjusted, which limits the range of movement of the monitoring device and makes it inconvenient to be used in laboratories with various spatial sizes. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a roving security camera to solve the problem that the roving monitoring devices mentioned in the background art can only move within the range of a slide, limiting the range of mobile monitoring and making them unsuitable for use in laboratories with various spatial sizes.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A roving security camera includes:

[0008] Security cameras;

[0009] A support structure, placed on the security camera, is used to support the security camera;

[0010] A movable structure, arranged on the supporting structure and the security camera, is used to control the horizontal movement of the security camera;

[0011] An adjustment structure, placed on the supporting structure, is used to increase the moving distance of the movable structure.

[0012] Preferably, the support structure includes:

[0013] Two U-shaped frames;

[0014] Two take-up rollers are rotatably mounted inside two U-shaped frames;

[0015] Two guide cables are respectively arranged on two take-up rollers, and the two guide cables are respectively wound around the two take-up rollers;

[0016] The carriage is positioned above the security camera and is movably mounted on two guide cables.

[0017] Preferably, the support structure further includes:

[0018] L-shaped connecting plates are arranged on the U-shaped frame;

[0019] Several mounting holes are provided on the L-shaped connecting plate.

[0020] Preferably, the moving structure includes:

[0021] Four pulleys are symmetrically mounted on the inner wall of the carriage.

[0022] The pulley seat is slidably installed inside the carriage;

[0023] Four pulleys are symmetrically mounted on both sides of the pulley seat, and the guide cable is located between the corresponding pulleys.

[0024] The motor is located on one side of the carriage, and the output end of the motor is located on the corresponding pulley.

[0025] The extrusion assembly is arranged on the pulley seat.

[0026] Preferably, the extrusion assembly includes:

[0027] The guide rod is slidably mounted inside the carriage and positioned above the pulley seat;

[0028] The spring is slidably mounted on the guide rod, with one end of the spring arranged on the inner wall of the carriage and the other end of the spring arranged on one side of the pulley seat.

[0029] Preferably, the adjustment structure includes:

[0030] The connecting shaft is located inside the take-up roller and is rotatably mounted inside the U-shaped frame.

[0031] The worm gear is fixedly sleeved on one end of the connecting shaft;

[0032] Both bearing seats are located on one side of the U-shaped frame;

[0033] The linkage shaft is rotatably mounted inside two shaft seats;

[0034] The worm is fixedly sleeved on the linkage shaft, and the worm meshes with the worm wheel;

[0035] The limiting component, arranged on the shaft seat, is used to limit the angle of the linkage shaft.

[0036] Preferably, the limiting component includes:

[0037] The compression screw is threaded inside the shaft seat;

[0038] A rubber pad is placed at one end of the pressure screw and in contact with the surface of the linkage shaft.

[0039] Preferably, the limiting component further includes several anti-slip grooves, which are evenly distributed on the linkage shaft and correspond to the rubber pads.

[0040] The beneficial effects of this utility model are as follows:

[0041] In use, the L-shaped connecting plates on both sides can be fixed to the wall or bracket with bolts. The guide cable can be straightened to provide support for the carriage and security camera. By turning on the motor, the carriage and security camera can be controlled to move horizontally along the direction of the guide cable, so as to achieve the effect of patrol monitoring by the security camera. Furthermore, by rotating the linkage shaft, the guide cable wound on the take-up roller can be wound up and down to change the moving distance and range of the security camera, which can be adjusted according to the space of the installation environment.

[0042] This invention utilizes the self-locking properties of the worm gear and worm to prevent the connecting shaft and the take-up roller from rotating and becoming loose. In conjunction with the rotating pressure screw, a portion of the rubber pad can be squeezed into the anti-slip groove, increasing the friction between the linkage shaft and the pressure screw, and further improving the stability of the connecting shaft and the take-up roller.

Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] Example 1:

[0054] like Figures 1 to 6 As shown, this utility model provides a roving security camera, including: a security camera 1 and a support structure arranged on the security camera 1 for supporting the security camera 1.

[0055] The support structure includes two U-shaped frames 2 and two take-up rollers 201 rotatably installed inside the two U-shaped frames 2, two guide cables 202 arranged on the two take-up rollers 201, the two guide cables 202 being wound around the two take-up rollers 201, and a slide 203 arranged above the security camera 1 and movably installed on the two guide cables 202. The take-up rollers 201 can be used to take up and unwind the guide cables 202, and the guide cables 202 are used to support the slide 203 and the security camera 1.

[0056] The supporting structure also includes an L-shaped connecting plate 204 arranged on the U-shaped frame 2, and several mounting holes 205 opened on the L-shaped connecting plate 204, through which bolts can be passed to fix the L-shaped connecting plate 204 and the U-shaped frame 2 to the wall or bracket.

[0057] Example 2:

[0058] Based on Embodiment 1, in order to facilitate the control of the security camera 1 to move back and forth for inspection, a moving structure for controlling the horizontal movement of the security camera 1 is arranged on the support structure and the security camera 1.

[0059] The movable structure includes four pulleys 3 symmetrically rotated and mounted on the inner wall of the slide 203, a pulley seat 301 slidably mounted inside the slide 203, four pulleys 302 symmetrically rotated and mounted on both sides of the pulley seat 301, a guide cable 202 located between the corresponding pulleys 3 and 302, a motor 303 arranged on one side of the slide 203, the output end of the motor 303 arranged on the corresponding pulley 3, and a pressing component arranged on the pulley seat 301. By turning on the motor 303, the corresponding pulley 3 can be driven to roll on the guide cable 202, thereby moving the slide 203. When the slide 203 moves, it can drive the pulleys 302 to roll on the guide cable 202, thereby moving the security camera 1 horizontally and changing the monitoring position.

[0060] Specifically, the extrusion assembly includes a guide rod 304 slidably installed inside the slide 203 and arranged above the pulley seat 301, and a spring 305 slidably sleeved on the guide rod 304. One end of the spring 305 is arranged on the inner wall of the slide 203, and the other end of the spring 305 is arranged on one side of the pulley seat 301. Under the elastic force of the spring 305, the slide 203 can be driven to slide on the guide rod 304 and move upward, ensuring that the pulley 3 can move close to the guide cable 202.

[0061] Example 3:

[0062] Based on Embodiment 1, in order to adjust the moving range of the security camera 1, an adjustment structure for increasing the moving distance of the moving structure is arranged on the support structure.

[0063] The adjustment structure includes a connecting shaft 4 arranged inside the take-up roller 201, which is rotatably installed inside the U-shaped frame 2. A worm gear 401 is fixedly sleeved on one end of the connecting shaft 4. Two bearing seats 402 are arranged on one side of the U-shaped frame 2. A linkage shaft 403 is rotatably installed inside the two bearing seats 402. A worm 404 is fixedly sleeved on the linkage shaft 403 and meshes with the worm gear 401. A limiting component is arranged on the bearing seat 402 to limit the angle of the linkage shaft 403. Rotating the linkage shaft 403 can drive the worm 404 to rotate. The worm 404 can drive the connecting shaft 4 to rotate through meshing with the worm gear 401, thereby driving the take-up roller 201 to rotate and take up and unload the guide cable 202. Adjusting the length of the guide cable 202 changes the moving distance of the security camera 1.

[0064] Specifically, the limiting component includes a pressing screw 405 threaded inside the shaft seat 402, and a rubber pad 406 arranged at one end of the pressing screw 405 and in contact with the surface of the linkage shaft 403. Rotating the corresponding pressing screw 405 can cause the rubber pad 406 to disengage from the linkage shaft 403, thus releasing the angle restriction on the linkage shaft 403. Reverse rotation of the pressing screw 405 can cause the rubber pad 406 to press against the linkage shaft 403 again, thereby re-restricting the angle of the linkage shaft 403.

[0065] Specifically, the limiting component also includes several anti-slip grooves 407 evenly distributed on the linkage shaft 403. The anti-slip grooves 407 correspond to the rubber pads 406. When the rubber pads 406 are pressed against the linkage shaft 403, they will undergo a certain deformation, so that some of the rubber pads 406 can be pressed into the anti-slip grooves 407, thereby increasing the friction between the rubber pads 406 and the linkage shaft 403.

[0066] Working principle:

[0067] In use, bolts can be passed through the corresponding mounting holes 205 to fix the L-shaped connecting plate 204 and the U-shaped frame 2 to the wall or bracket. When in use, the motor 303 is turned on to drive the corresponding pulley 3 to rotate. When the pulley 3 rotates, it can roll on the guide cable 202 and drive the slide 203 to move, thereby driving the security camera 1 to move horizontally and change the monitoring position. While the slide 203 moves, it can drive the pulley seat 301 to move, thereby driving the pulley 302 to roll on the guide cable 202. Under the elastic force of the spring 305, the slide 203 can slide on the guide rod 304 and move upward, ensuring that the pulley 3 can move close to the guide cable 202.

[0068] Before installing the U-shaped bracket 2, the length of the guide cable 202 can be adjusted according to the distance the security camera 1 needs to move. During adjustment, the corresponding pressure screw 405 can be rotated. When the pressure screw 405 rotates, it moves through the threaded engagement with the shaft seat 402, causing the pressure screw 405 to disengage the rubber pad 406 from the linkage shaft 403. This releases the angle restriction on the linkage shaft 403. Subsequently, rotating the linkage shaft 403 drives the worm gear 404 to rotate. The rotating worm gear 404, through its engagement with the worm wheel… The engagement of 401 drives the connecting shaft 4 to rotate, which in turn drives the take-up roller 201 to rotate. The rotating take-up roller 201 can take up and unwind the guide cable 202, and adjust the length of the guide cable 202 to change the moving distance of the security camera 1. After adjustment, the pressure screw 405 can be rotated in the opposite direction, so that the pressure screw 405 drives the rubber pad 406 to press against the linkage shaft 403 again, which can restrict the angle of the linkage shaft 403 again and prevent the worm gear 401 from rotating and loosening from the connecting shaft 4.

[0069] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
