Description

Technical Field

[0001] This utility model relates to the field of anti-tamper technology for cameras, specifically an indoor monitoring camera device for dangerous goods transport vehicles with an anti-tamper structure. Background Technology

[0002] In the field of hazardous materials transportation, to ensure transportation safety, regulate driver behavior, and meet industry regulatory requirements, hazardous materials transport vehicles are typically equipped with indoor monitoring cameras to record key information such as operational conditions and abnormal events within the driver's cab in real time. This monitoring data is not only an important basis for enterprise safety management but also a crucial document for regulatory authorities to verify transportation compliance.

[0003] However, existing indoor surveillance camera devices used in hazardous materials transport vehicles generally suffer from weak anti-tampering performance. Specifically, existing cameras are mostly fixed using conventional mechanical screws and directly to the cab ceiling, dashboard, or other locations using simple plastic or metal bases. These fixing structures can be quickly disassembled using common disassembly tools such as ordinary screwdrivers, needle-nose pliers, and wrenches, resulting in a high risk of malicious damage or unauthorized removal of the cameras in actual use.

[0004] In summary, an indoor monitoring camera device for dangerous goods transport vehicles with an anti-tamper structure is proposed to solve the above problems. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an indoor monitoring camera device for dangerous goods transport vehicles with an anti-disassembly structure. It has the advantages of being difficult for unauthorized personnel to disassemble with simple tools, thus improving anti-disassembly performance and effectively preventing malicious damage. It solves the problem that existing indoor monitoring cameras for dangerous goods transport vehicles are easily disassembled.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An indoor monitoring camera device for dangerous goods transport vehicles with anti-disassembly structure, including a connecting plate, a connecting base, a camera module and a cylindrical tube, wherein the connecting base is provided with a camera module extending to its lower part, the bottom of the connecting plate is provided with countersunk holes arranged in a ring array and extending to the other side and adapted to bolts, the bottom of the connecting plate is provided with internally threaded cylinders arranged in a ring array and extending to the other side, and the bottom of the connecting plate is provided with alignment holes arranged symmetrically on the left and right sides and extending to the other side.

[0009] The top of the connecting seat is provided with a circular groove that fits the connecting plate. Inside the circular groove, ball-head posts that are symmetrically distributed and fit the alignment holes are fixedly connected. Inside the connecting seat, there is an annular stepped cavity extending to its bottom. Inside the annular stepped cavity, there are connecting components that are arranged in a ring array and extend into the circular groove and fit the internal threaded cylinder. Inside the annular stepped cavity, there are transmission components that mesh with the connecting components.

[0010] The inner and outer diameters of the cylindrical tube are respectively adapted to the inner and outer diameters of the lower end of the annular stepped cavity. The upper end of the cylindrical tube is provided with protruding strips arranged in a ring array and adapted to the transmission assembly. An anti-slip ring is fixedly connected to the outer side of the cylindrical tube.

[0011] The beneficial effects of this utility model are:

[0012] This tamper-proof indoor monitoring camera device for hazardous materials transport vehicles is installed by bolting a connecting plate to a flat surface inside the vehicle. A cylindrical tube is inserted into the annular stepped cavity from the bottom of the connecting seat. The cylindrical tube is rotated to fit over the transmission assembly. The connecting seat is then fitted over the connecting plate through a circular groove. The connecting seat is rotated to align the ball joint with the alignment hole and insert it. At this point, the connecting assembly and the internally threaded tube are in contact and aligned. Rotating the cylindrical tube via an anti-slip ring drives the transmission assembly to rotate. Since both the transmission assembly and the connecting assembly are engaged, they rotate synchronously, causing the connecting assembly and the cylindrical tube to connect threadedly until the top of the connecting seat is tightly fitted against the flat surface of the vehicle's interior. Rotation of the cylindrical tube is then stopped, and the device is pulled out. The device is now installed. Disassembly requires the cylindrical tube, making it difficult for unauthorized personnel to disassemble with simple tools, thus improving tamper resistance and effectively preventing malicious damage.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the transmission assembly includes a transmission ring, an internal gear ring, and strip-shaped grooves. The transmission ring is rotatably connected inside the annular stepped cavity. The outer diameter of the transmission ring is adapted to the inner diameter of the cylindrical tube. An internal gear ring that meshes with the gears is fixedly connected to the inner side of the transmission ring. Strip-shaped grooves that are distributed in an annular array and adapted to the raised strips are opened on the outer side of the transmission ring.

[0015] Furthermore, the connecting assembly includes a lead screw and gears. The annular stepped cavity is rotatably connected to a lead screw that is arranged in a ring array and extends into a circular groove and is adapted to the internal threaded cylinder. The outer side of the lead screw is fixedly connected to a gear located inside the annular stepped cavity.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the cylindrical tube is inserted into the annular stepped cavity from the bottom of the connecting seat. The cylindrical tube is rotated so that the protruding strip on its inner side aligns with the strip-shaped groove on the outer side of the transmission ring and is inserted, so that the cylindrical tube is fitted on the outer side of the transmission ring. The connecting seat is fitted on the outer side of the connecting plate through the circular groove. The connecting seat is rotated so that the ball head is aligned with the alignment hole and inserted. At this time, the screw and the internal threaded tube are in contact and aligned. The cylindrical tube is rotated through the anti-slip ring, which in turn drives the transmission ring to rotate. The transmission ring drives the internal gear ring to rotate. Since the internal gear ring and the gear are meshed, the screw is driven to rotate synchronously through the gear, so that the screw and the cylindrical tube are threadedly connected until the top of the connecting seat is tightly fitted with the flat surface of the vehicle interior. The rotation of the cylindrical tube is stopped and it is pulled out. The device is now installed. When the device is disassembled, it must be disassembled through the cylindrical tube, which makes it difficult for unauthorized personnel to disassemble with simple tools, thus improving the anti-disassembly performance and effectively preventing malicious damage.

This utility model includes a connecting plate 1, a connecting seat 2, a camera module 3, and a cylindrical tube 4. The connecting seat 2 has a camera module 3 extending to its lower part inside. The bottom of the connecting plate 1 has countersunk holes 5 arranged in a ring array and extending to the other side and adapted to bolts. The bottom of the connecting plate 1 has an internally threaded cylinder 6 arranged in a ring array and extending to the other side. The bottom of the connecting plate 1 has alignment holes 7 arranged symmetrically on both sides and extending to the other side.

[0024] The top of the connecting seat 2 is provided with a circular groove 8 that is adapted to the connecting plate 1. The circular groove 8 is fixedly connected with ball-head posts 9 that are symmetrically distributed on the left and right and adapted to the alignment holes 7. The connecting seat 2 is provided with an annular stepped cavity 10 extending to its bottom. The annular stepped cavity 10 is provided with connecting components 11 that are arranged in a ring array and extend into the circular groove 8 and are adapted to the internal threaded cylinder 6. The annular stepped cavity 10 is provided with a transmission component 12 that meshes with the connecting component 11.

[0025] The inner and outer diameters of the cylindrical tube 4 are respectively adapted to the inner and outer diameters of the lower end of the annular stepped cavity 10. The upper end of the cylindrical tube 4 is provided with protruding strips 13 arranged in a ring array and adapted to the transmission assembly 12. The outer side of the cylindrical tube 4 is fixedly connected with an anti-slip ring 14.

[0026] The transmission assembly 12 includes a transmission ring 121, an inner gear ring 122, and a strip-shaped groove 123. The transmission ring 121 is rotatably connected inside the annular stepped cavity 10. The outer diameter of the transmission ring 121 is adapted to the inner diameter of the cylindrical tube 4. The inner side of the transmission ring 121 is fixedly connected to the inner side of the transmission ring 122, which meshes with the gear 112. The outer side of the transmission ring 121 is provided with strip-shaped grooves 123 arranged in a ring array and adapted to the protruding strips 13.

[0027] The connecting assembly 11 includes a lead screw 111 and a gear 112. The annular stepped cavity 10 is rotatably connected to a lead screw 111 that is arranged in a ring array and extends into the circular groove 8 and is adapted to the internal threaded cylinder 6. The outer side of the lead screw 111 is fixedly connected to a gear 112 located inside the annular stepped cavity 10.

[0028] Insert the cylindrical tube 4 into the annular stepped cavity 10 from the bottom of the connecting seat 2. Rotate the cylindrical tube 4 so that the protruding strip 13 on its inner side aligns with the strip-shaped groove 123 on the outer side of the transmission ring 121 and insert it, so that the cylindrical tube 4 is fitted onto the outer side of the transmission ring 121. Fit the connecting seat 2 onto the outer side of the connecting plate 1 through the circular groove 8. Rotate the connecting seat 2 so that the ball head 9 is aligned with the alignment hole 7 and inserted. At this time, the lead screw 111 and the internal threaded cylinder 6 are in contact and aligned. Rotate the cylindrical tube 4 through the anti-slip ring 14, which in turn drives the transmission ring 121 to rotate. The transmission ring 121 thus... The internal gear ring 122 is driven to rotate. Since the internal gear ring 122 and gear 112 are meshed, the lead screw 111 is driven to rotate synchronously through gear 112, so that the lead screw 111 and the cylindrical cylinder 4 are threaded together until the top of the connecting seat 2 is tightly attached to the flat surface of the vehicle interior. Then the rotation of the cylindrical cylinder 4 is stopped and it is pulled out. The device is now installed. When disassembling the device, it must be done through the cylindrical cylinder 4. This makes it difficult for unauthorized personnel to disassemble with simple tools, thus improving the anti-disassembly performance and effectively preventing malicious damage.

[0029] Working principle:

[0030] Step 1: Fix the connecting plate 1 to a flat area inside the dangerous goods transport vehicle using bolts. Insert the cylindrical tube 4 into the annular stepped cavity 10 from the bottom of the connecting seat 2. Rotate the cylindrical tube 4 so that the protruding strip 13 on its inner side aligns with the strip groove 123 on the outer side of the transmission ring 121 and inserts it, so that the cylindrical tube 4 fits on the outer side of the transmission ring 121.

[0031] Step 2: Fit the connecting seat 2 onto the outside of the connecting plate 1 through the circular groove 8, rotate the connecting seat 2 so that the ball head 9 is aligned with the alignment hole 7 and inserted. At this time, the lead screw 111 and the internal threaded cylinder 6 are in contact and aligned.

[0032] Step 3: Rotate the cylindrical cylinder 4 through the anti-slip ring 14, which in turn drives the transmission ring 121 to rotate. The transmission ring 121 then drives the inner gear ring 122 to rotate. Since the inner gear ring 122 and the gear 112 are meshed, the gear 112 drives the lead screw 111 to rotate synchronously, so that the lead screw 111 and the cylindrical cylinder 4 are threaded together until the top of the connecting seat 2 is tightly attached to the flat surface of the vehicle interior. Stop rotating the cylindrical cylinder 4 and pull it out. The device is now installed. When disassembling the device, it must be done through the cylindrical cylinder 4.
