Description

Technical Field

[0001] This utility model relates to the technical field of building security monitoring devices, and in particular to a building security monitoring device. Background Technology

[0002] Building management has always been one of the most important public welfare management issues. Building security is related to the personal and property safety of residents. Therefore, it is particularly important to implement strict and comprehensive security monitoring measures for buildings. The existing patent CN210485191U, "A Building Security Monitoring Device for Easy Disassembly," discloses that "when it is necessary to disassemble and maintain the monitoring device, the inclined blocks are pulled to both sides by a pull ring, causing the inclined blocks to disengage from the through hole and move into the storage hole. Then, the user removes the conical column along with the monitoring device body from inside the sleeve, completing the disassembly of the monitoring device." Although this technical solution solves the problem of inconvenient disassembly and assembly of high-altitude ceiling cameras, in actual operation, climbing tools such as ladders are still required to pull the pull ring to disassemble the monitoring device, which increases the risk of disassembly and assembly work to some extent.

[0003] The purpose of this utility model is to provide a building security monitoring device in order to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A building security monitoring device includes a connecting plate, a T-shaped column, and a camera body. The camera body is installed at the bottom of the T-shaped column. The connecting plate is detachably connected to the T-shaped column. A fixed column is fixedly connected to the bottom side of the connecting plate. A movable truncated cone is movably fitted on the fixed column. An inverted fixed truncated cone is fixedly connected to the bottom end of the fixed column. The two sets of truncated cones are identical in shape. A first spring is fitted on the fixed column. The two ends of the first spring are respectively fixed to the connecting plate and the movable truncated cone. A groove for accommodating the fixed truncated cone is opened on the T-shaped column. Square grooves communicating with the groove are opened on both sides of the horizontal end of the T-shaped column. An inclined block is slidably arranged in the square groove. A second spring is fixedly connected between the opposite end faces of the square groove and the inclined block. The inclined surface of the inclined block is adapted to the conical surface of the fixed truncated cone.

[0006] As a further description of the above technical solution:

[0007] T-shaped rods are installed through both sides of the horizontal end of the T-shaped column. One end of the T-shaped rod is fixedly connected to the inclined block. A second spring is sleeved on the T-shaped rod, and the two ends of the second spring are fixedly connected to the square groove and the inclined block, respectively.

[0008] As a further description of the above technical solution:

[0009] The top of the movable truncated cone is fixedly connected to a boss that is movably sleeved on the fixed column, and the two ends of the first spring are fixedly connected to the connecting plate and the boss, respectively.

[0010] As a further description of the above technical solution:

[0011] The fixed column is provided with guide grooves around its perimeter, and guide blocks that slide in cooperation with the guide grooves are fixedly connected to the hole walls of the boss and the movable cone.

[0012] As a further description of the above technical solution:

[0013] It also includes a shift fork rod, which includes a U-shaped rod and a vertical rod fixed to the bottom side of the horizontal end of the U-shaped rod.

First, the T-shaped column is pushed upwards using a lever, causing the movable cone to move the two inclined blocks outwards into the square groove. Under the elastic action of the first spring, the bottom side of the movable cone contacts the top side of the fixed cone. The T-shaped column is then pushed upwards, and under the elastic action of the second spring, the two inclined blocks contact the conical surface of the movable cone. Then, the lever supports the T-shaped column to move downwards, causing the two inclined blocks to slide downwards along the conical surface of the movable cone until the inclined blocks move down with the T-shaped column to the conical surface of the fixed cone. At this point, the engagement between the inclined blocks and the fixed cone is released, allowing for the disassembly and assembly of the camera body. The structure is simple, the operation is convenient, and the risk of disassembly and assembly is reduced. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a building security monitoring device, including a connecting plate 1, a T-shaped column 6, and a camera body 8. The connecting plate 1 is fixedly connected to the ceiling 15 by several bolts 2. The camera body 8 is installed at the bottom of the T-shaped column 6. A fixed column 10 is fixedly connected to the bottom side of the connecting plate 1. A movable truncated cone 4 is movably fitted on the fixed column 10. An inverted fixed truncated cone 5 is fixedly connected to the bottom end of the fixed column 10. The two sets of truncated cones are identical in shape. A first spring 3 is fitted on the fixed column 10. A boss 1 movably fitted on the fixed column 10 is fixedly connected to the top of the movable truncated cone 4. 1. The two ends of the first spring 3 are fixedly connected to the connecting plate 1 and the boss 11 respectively. The T-shaped column 6 has a groove 602 for accommodating the fixed truncated cone 5. T-shaped rods 12 are provided through the horizontal ends of the T-shaped column 6. Square grooves 601 communicating with the grooves 602 are provided on the horizontal ends of the T-shaped column 6. Inclined blocks 7 are slidably arranged in the square grooves 601. One end of the T-shaped rod 12 is fixedly connected to the inclined block 7. The second spring 13 is sleeved on the T-shaped rod 12. The two ends of the second spring 13 are fixedly connected to the square groove 601 and the inclined block 7 respectively. The inclined surface of the inclined block 7 is adapted to the conical surface of the fixed truncated cone 5.

[0025] Under the elastic action of the second spring 13, the two inclined blocks 7 slide to the top of the fixed cone 5, and the two T-shaped rods 12 and the inclined blocks 7 are engaged with the fixed cone 5, and the camera body 8 is installed on the ceiling 15. Pushing the T-shaped column 6 upward, the movable cone 4 pushes the two inclined blocks 7 to move outward to enter the square groove 601. Under the elastic action of the first spring 3, the bottom side of the movable cone 4 is pushed to contact the top side of the fixed cone 5. Continue to push the T-shaped column 6 upward. Under the elastic action of the second spring 13, the two inclined blocks 7 contact the conical surface of the movable cone 4. Then, the T-shaped column 6 moves downward, so that the two inclined blocks 7 slide down along the conical surface of the movable cone 4 until the inclined blocks 7 move down with the T-shaped column 6 to the conical surface of the fixed cone 5. At this time, the engagement between the inclined blocks 7 and the fixed cone 5 is released, and the camera body 8 can be disassembled and assembled. The structure is simple and the operation is convenient.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, guide grooves 1001 are provided around the fixed column 10, and guide blocks 14 that slide in cooperation with guide grooves 1001 are fixedly connected to the hole walls of the boss 11 and the movable cone 4 to improve the smoothness of movement of the movable cone 4.

[0027] Specifically, such as Figure 4 As shown, the shift fork lever 9 includes a U-shaped rod and a vertical rod fixed to the bottom side of the horizontal end of the U-shaped rod. The horizontal end of the T-shaped column 6 has positioning holes 603 on both sides that mate with the vertical ends of the U-shaped rod. The worker holds the vertical rod on the ground and aligns the U-shaped rod with the positioning holes 603. The T-shaped column 6 can be pushed upward and released downward. After the T-shaped column 6 is separated from the fixed cone 5, the camera body 8 is lowered under the support of the shift fork lever 9, reducing the risk of disassembly and assembly.

[0028] Working principle: During use, the operator holds a vertical rod on the ground and aligns the U-shaped rod with the positioning hole 603. First, the T-shaped column 6 is pushed upward by the lever 9. The movable cone 4 pushes the two inclined blocks 7 outward to enter the square groove 601. Under the elastic action of the first spring 3, the bottom side of the movable cone 4 is pushed to contact the top side of the fixed cone 5. The T-shaped column 6 is pushed upward. Under the elastic action of the second spring 13, the two inclined blocks 7 contact the conical surface of the movable cone 4. Then, the lever 9 supports the T-shaped column 6 to move downward, so that the two inclined blocks 7 slide downward along the conical surface of the movable cone 4 until the inclined blocks 7 move down with the T-shaped column 6 to the conical surface of the fixed cone 5. At this point, the engagement between the inclined blocks 7 and the fixed cone 5 is released, and the camera body 8 can be disassembled and assembled. The structure is simple, the operation is convenient, and the risk of disassembly and assembly is reduced.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
