Description

Technical Field

[0001] This utility model relates to the field of surveillance equipment technology, specifically a bullet camera. Background Technology

[0002] Bullet cameras are named for their resemblance to pistols. Their internal configurations and quality vary greatly. In the low-to-mid-range market, you can find many products that look exactly the same, but their quality and price differ significantly. The main requirement for bullet camera surveillance is that it is suitable for areas with insufficient light and areas where lighting equipment cannot be installed at night. When only monitoring the position or movement of objects, bullet cameras can be selected.

[0003] In the prior art, such as Chinese Patent Publication No. CN112040111B, a waterproof bullet camera is disclosed, including a mounting base, a drive motor mounted on the top of the mounting base, a mounting plate fixedly connected to the output end of the drive motor, an adjustment component mounted on the top of the mounting plate, a protective shell mounted on the top of the adjustment component, and a camera body installed inside the protective shell. By controlling the extension and retraction of the first electric push rod, the angle of the rotating plate can be adjusted. When the rotating plate is unfolded, the inclined plate and the rotating plate form a water-blocking plate, which can waterproof the bullet camera installed outdoors, prevent rainwater from contacting the camera body, and make the camera body safer. Moreover, the rotating plate and the inclined plate, together with the protective shell, can protect the camera body and prevent external force from damaging the camera body, thereby extending the service life of the camera body.

[0004] However, in existing bullet cameras, once the shooting angle is adjusted, the angle is rigidly fixed. During use, if encountering severe weather such as strong winds or hail, or if debris or hail blown into the air by the strong winds hits the camera, or if other external forces hit the camera, the rigidity of the camera causes it to bear the full impact force, which can easily lead to damage to the camera. Furthermore, after being impacted, the rigidity can easily cause plastic deformation, making the camera unable to work properly. Utility Model Content

[0005] The purpose of this invention is to provide a bullet camera to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bullet camera, comprising:

[0008] The main body of the bullet camera has a support rod fixedly connected to its bottom, a connecting ball fixedly installed at the bottom end of the support rod, and an upper fixed frame fixedly installed at the bottom of the main body of the camera.

[0009] A spherical shell is fitted onto the surface of a connecting sphere, and an extension rod is fixedly installed on the surface of the spherical shell;

[0010] A support frame is fixedly installed at the bottom of the spherical shell. A sector-shaped worm gear is fixedly installed at the bottom of the support frame. A lower fixed frame is fixedly connected to one side of the support frame. A breakable connector is provided between the lower fixed frame and the upper fixed frame. A rotating frame is provided below the support frame. A worm gear is rotatably installed inside the rotating frame.

[0011] Preferably, the surface of the connecting ball is fixedly connected to a slider by a traction rope, and multiple sets of sliders are arranged in a circumferential array on the side of the connecting ball.

[0012] Preferably, the surface of the upper fixing frame is provided with a first threaded hole.

[0013] Preferably, the spherical shell is rotatably connected to the connecting ball, and the interior of the spherical shell has multiple sets of clearance grooves, which correspond one-to-one with multiple sets of sliders.

[0014] Preferably, multiple sets of extension rods are provided. The extension rods have connecting holes and sliding grooves inside. The positions of the extension rods correspond to the positions of the relief grooves. The relief grooves and sliding grooves are connected through the connecting holes. The slider is slidably disposed inside the sliding groove. A return spring is provided between the side of the slider near the connecting ball and the inner wall of the sliding groove.

[0015] Preferably, a support ring is fixedly connected to the bottom of the support frame, and the support ring is disposed on both sides of the sector-shaped worm gear.

[0016] Preferably, the lower fixing frame is disposed below the upper fixing frame, and the surface of the lower fixing frame is provided with a second threaded hole.

[0017] Preferably, the two ends of the easily breakable connector are respectively fixedly connected to an upper connecting plate and a lower connecting plate. The upper connecting plate is detachably connected to the upper fixing frame through bolts and a first threaded hole, and the lower connecting plate is detachably connected to the lower fixing frame through bolts and a second threaded hole.

[0018] Preferably, a fixed shaft is fixedly installed inside the rotating frame, and the sector worm gear and the support ring are both rotatably sleeved on the surface of the fixed shaft.

[0019] Preferably, the worm gear meshes with a sector worm wheel, and a drive motor is fixedly connected to one end of the worm gear.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By incorporating a breakable connector, when an external force impacts the camera, if the force is too great, the breakable connector will break under the impact force, thus preventing the camera from directly bearing all the external force and reducing the probability of the camera being damaged due to external impact.

[0022] 2. By setting up a connecting ball and a spherical shell, when the main body of the bullet camera is impacted by an external force, the connecting ball rotates inside the spherical shell, causing the slider to compress the return spring. When the external force disappears, under the rebound action of the return spring, the slider drives the connecting ball back to the initial position through the traction rope, thereby restoring the angle of the main body of the bullet camera and ensuring the normal operation of the camera.

[0023] 3. By detachably installing the upper and lower connecting plates onto the surfaces of the upper and lower fixed frames respectively, when the easily broken connecting parts break, the upper and lower connecting plates can be removed and replaced with new easily broken connecting parts for installation. This makes maintenance convenient and highly practical. Attached Figure Description

[0031] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0032] Please see the appendix Figure 1 To be continued Figure 6 As shown, this utility model provides a bullet camera, including:

[0033] A bullet camera body 1 has a support rod 11 fixedly connected to its bottom. A connecting ball 12 is fixedly installed at the bottom end of the support rod 11. A slider 14 is fixedly connected to the surface of the connecting ball 12 by a traction rope 13. Multiple sets of sliders 14 are arranged in a circular array on the side of the connecting ball 12. An upper fixing frame 16 is fixedly installed at the bottom of the camera body 1. A first threaded hole 17 is opened on the surface of the upper fixing frame 16.

[0034] A spherical shell 2 is fitted onto the surface of the connecting ball 12 and is rotatably connected to the connecting ball 12. Multiple sets of clearance grooves 21 are formed inside the spherical shell 2, each set corresponding to a set of sliders 14. Multiple extension rods 22 are fixedly mounted on the surface of the spherical shell 2. Each extension rod 22 has a connecting hole 23 and a sliding groove 24 inside. The position of the extension rod 22 corresponds to the position of the clearance groove 21. The clearance groove 21 and the sliding groove 24 are connected through the connecting hole 23. The slider 14 is slidably disposed inside the sliding groove 24. A return spring 15 is provided between the side of the slider 14 closest to the connecting ball 12 and the inner wall of the sliding groove 24.

[0035] A support frame 3 is fixedly mounted on the bottom of the spherical shell 2. A sector-shaped worm gear 31 is fixedly installed on the bottom of the support frame 3. A support ring 32 is fixedly connected to the bottom of the support frame 3, and the support ring 32 is located on both sides of the sector-shaped worm gear 31. A lower fixing frame 33 is fixedly connected to one side of the support frame 3. The lower fixing frame 33 is located below the upper fixing frame 16. A second threaded hole 34 is opened on the surface of the lower fixing frame 33. A breakable connector 5 is provided between the lower fixing frame 33 and the upper fixing frame 16. An upper connecting plate 51 is fixedly connected to both ends of the breakable connector 5. The upper connecting plate 51 is detachably connected to the upper fixed frame 16 via bolts and the first threaded hole 17, and the lower connecting plate 52 is detachably connected to the lower fixed frame 33 via bolts and the second threaded hole 34. A rotating frame 4 is provided below the support frame 3. A fixed shaft 43 is fixedly installed inside the rotating frame 4. The sector worm gear 31 and the support ring 32 are both rotatably sleeved on the surface of the fixed shaft 43. A worm 41 is rotatably installed inside the rotating frame 4. The worm 41 meshes with the sector worm gear 31. A drive motor 42 is fixedly connected to one end of the worm 41.

[0036] The present invention discloses a bullet camera. In use, the upper connecting plate 51 is connected to the upper fixed frame 16 by bolts, and the lower connecting plate 52 is connected to the lower fixed frame 33. The drive motor 42 drives the worm gear 41 to rotate, and the rotation of the worm gear 41 drives the sector worm wheel 31 to rotate. The sector worm wheel 31 drives the angle of the bullet camera body 1 to change through the spherical shell 2 and the support rod 11, thereby realizing the adjustment of the angle of the bullet camera body 1. Through the self-locking characteristics of the worm gear 41 and the sector worm wheel 31, the angle of the bullet camera body 1 can be effectively prevented from changing during use.

[0037] By setting up the easily breakable connector 5, when an external force hits the camera, if the external force is too large, the easily breakable connector 5 will break under the impact force, thereby preventing the camera from directly bearing all the external force and reducing the probability of the camera being damaged due to external impact.

[0038] As a further improvement of this utility model, the support rod 11 is connected to the support frame 3 through the spherical shell 2. When the main body of the bullet camera 1 is impacted by an external force during use, causing the easily broken connecting piece 5 to break, the main body of the bullet camera 1 drives the connecting ball 12 to rotate inside the spherical shell 2 through the support rod 11. During the rotation of the connecting ball 12, the slider 14 moves inside the slide groove 24 through the traction rope 13, compressing the reset spring 15, thereby offsetting the impact force. When the external force disappears, under the rebound action of the reset spring 15, the slider 14 drives the connecting ball 12 back to the initial position through the traction rope 13, thereby restoring the angle of the main body of the bullet camera 1.

[0039] By setting up a connecting ball 12 and a spherical shell 2, when the main body 1 of the bullet camera is impacted by an external force, the connecting ball 12 rotates inside the spherical shell 2, causing the slider 14 to press against the reset spring 15. When the external force disappears, under the rebound action of the reset spring 15, the slider 14 drives the connecting ball 12 back to the initial position through the traction rope 13, thereby resetting the angle of the main body 1 of the bullet camera and ensuring the normal operation of the camera.

[0040] As a further improvement of this utility model, the upper connecting plate 51 and the lower connecting plate 52 are detachably installed on the surfaces of the upper fixing frame 16 and the lower fixing frame 33, respectively. When the easily broken connecting piece 5 breaks, the upper connecting plate 51 and the lower connecting plate 52 can be removed respectively, and then a new easily broken connecting piece 5 can be installed. This makes maintenance convenient and highly practical.

[0041] Working Principle: The gun-type camera, named for its resemblance to a pistol, utilizes a method where the upper connecting plate 51 is bolted to the upper fixed frame 16, and the lower connecting plate 52 is bolted to the lower fixed frame 33. A drive motor 42 rotates the worm gear 41, which in turn rotates the sector worm wheel 31. The sector worm wheel 31, through the spherical housing 2 and support rod 11, changes the angle of the gun-type camera body 1, thus adjusting its angle. The self-locking characteristic of the worm gear 41 and sector worm wheel 31 effectively prevents changes in the angle of the gun-type camera body 1 during use. When a force impacts the camera, if the external force is too large, the easily broken connector 5 will break under the action of the impact force, thus preventing the camera from directly bearing all the external force. After the easily broken connector 5 breaks, the main body 1 of the bullet camera drives the connecting ball 12 to rotate inside the spherical shell 2 through the support rod 11. During the rotation of the connecting ball 12, the slider 14 moves inside the slide groove 24 through the traction rope 13, compressing the return spring 15, thereby offsetting the impact force. When the external force disappears, under the rebound action of the return spring 15, the slider 14 drives the connecting ball 12 back to the initial position through the traction rope 13, thereby restoring the angle of the main body 1 of the bullet camera.
