Description

Technical Field

[0001] This utility model relates to the field of lighting and monitoring equipment technology, specifically to an extended telescopic pole and its reinforcement device. Background Technology

[0002] As a core link in the national economic logistics system, railway freight undertakes long-distance transportation of bulk commodities such as coal, grain, and industrial equipment, with freight containers serving as the core carriers of these goods. With freight volume increasing annually and freight container turnover frequency rising, the structural integrity of the containers and the stability of cargo loading directly impact transportation safety. Problems with freight containers can lead to minor losses of goods or, in severe cases, major accidents such as foreign object intrusion into the tracks or train derailment. The core objective of freight container inspection is to proactively identify these risks. Currently, the industry has not fully automated inspection and still relies primarily on a "manual-based, equipment-assisted" model. Existing auxiliary methods are limited to tools such as handheld flashlights, high-definition cameras, and simple rangefinders. Some marshalling yards have attempted to introduce drones for low-altitude inspections, but coverage is low due to complex electromagnetic environments and container obstructions, and many scenarios still require manual supplementary inspections. Furthermore, data recording relies on paper forms or basic apps, lacking real-time data transmission and intelligent analysis capabilities, making it difficult to meet the needs of "real-time early warning and rapid response."

[0003] Most existing inspection equipment uses fixed support poles with cameras mounted at the top. This design prevents the overall height from being adjusted for different situations, and high-altitude operations pose certain safety hazards. Therefore, we need to propose an extended telescopic pole and its reinforcement device. Utility Model Content

[0004] The purpose of this utility model is to provide an extended telescopic pole and its reinforcement device, which can quickly adjust the length of the pole according to different needs, and can lower the height of the camera when maintenance is required, thereby reducing safety hazards of high-altitude operations, facilitating maintenance, and improving the stability and risk resistance of the pole structure, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides: an extended telescopic pole and its reinforcement device, comprising a first extension pole, a fixed bracket, and a camera body; the first extension pole is installed on the top of the base, and a second extension pole and a third extension pole are sequentially and movably installed inside the first extension pole; the first, second, and third extension poles are all provided with a spiral reinforcing skeleton for enhancing shear resistance; the bottom end of the second extension pole is provided with a quick-connect assembly for fixing the extension length of the telescopic pole; the top of the inner wall of the first extension pole is provided with a threaded connection part that mates with the quick-connect assembly; and the top of the third extension pole is movably connected to a camera body for monitoring via the fixed bracket.

[0006] Preferably, the quick-connect assembly includes: a limiting anti-detachment disc connected to the bottom end of the second extension rod, and a locking connection part connected to the bottom end of the surface of the second extension rod; wherein, the outer surface of the locking connection part is engaged with the threaded connection part, and an elastic washer is provided at the bottom of the locking connection part.

[0007] Preferably, the elastic washer is fixedly connected to the surface of the limiting anti-detachment disc, and the surface of the limiting anti-detachment disc is slidably connected to the inner wall of the first extension rod.

[0008] Preferably, the fixed bracket is fixedly installed at the top of the third extension rod, the bottom of the fixed bracket is connected to a universal module, and the camera body is movably installed on the adjustment end of the universal module.

[0009] On the other hand, this utility model proposes a reinforcement device, including the aforementioned extended telescopic rod, and also includes a fixing cylinder installed on the surface of the first extension rod and fixing slots distributed on the surface of the locking connection part at the bottom end of the second extension rod. The fixing cylinder is provided with a locking component for reinforcing the telescopic rod, and the fixing block of the locking component is movably inserted into the inner wall of the fixing slot.

[0010] Preferably, the locking assembly includes: a connecting baffle disposed on the inner wall of the fixed cylinder, and a positioning shaft connected to one side of the surface of the connecting baffle; wherein, the inner wall of the fixed cylinder is provided with a limiting guide groove communicating with the interior of the first extension rod, the fixing block is fixedly installed on the surface of the connecting baffle, and the two side surfaces of the fixing block are slidably connected to the inner wall of the limiting guide groove.

[0011] Preferably, a fixing spring is provided inside the fixing cylinder, the fixing spring is fitted onto the surface of the positioning shaft, and one end of the positioning shaft is provided with an adjustment through hole located outside the fixing cylinder.

[0012] Preferably, it further includes: an auxiliary module disposed on the fixed bracket, the auxiliary module being provided with an illumination element; and a monitoring module disposed on the first extension rod, the monitoring module being communicatively connected to the auxiliary module and the camera body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a combination of a first extension rod, a spiral reinforcing skeleton, and a quick-connect assembly. The spiral reinforcing skeleton within the first, second, and third extension rods effectively enhances the overall shear and bending resistance of the telescopic rod, preventing deformation due to external forces or its own weight during extension and ensuring high structural stability even after extension. The quick-connect assembly, combined with the threaded connection, allows for rapid locking and releasing between the second and first extension rods, ensuring a simple and secure connection. The elastic washer enhances the sealing and anti-loosening capabilities of the threaded connection, preventing loosening due to vibration and extending its service life. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides: an extended telescopic pole and its reinforcement device, including a first extension pole 2, a fixed bracket 5, and a camera body 7; the first extension pole 2 is installed on the top of the base 1, and a second extension pole 3 and a third extension pole 4 are movably installed inside the first extension pole 2 in sequence; the first extension pole 2, the second extension pole 3, and the third extension pole 4 are all provided with a spiral reinforcing skeleton 9 for enhancing shear resistance; the bottom end of the second extension pole 3 is provided with a quick-connect assembly for fixing the extension length of the telescopic pole; the top of the inner wall of the first extension pole 2 is provided with a threaded connection part 10 that cooperates with the quick-connect assembly; the top of the third extension pole 4 is movably connected to the camera body 7 for monitoring through the fixed bracket 5.

[0024] It is worth noting that, through the coordinated arrangement of the first extension rod 2, the fixed bracket 5, the spiral reinforcing frame 9, and the quick-connect assembly, the length of the support rod can be quickly adjusted according to different road requirements. Furthermore, when maintenance is required, the height of the camera can be lowered to reduce safety hazards associated with high-altitude operations, facilitate maintenance, and improve the stability and risk resistance of the support rod structure.

[0025] Specifically, the quick-connect assembly includes: a limiting anti-detachment disc 11 connected to the bottom end of the second extension rod 3, and a locking connection part 13 connected to the bottom end of the surface of the second extension rod 3; wherein, the outer surface of the locking connection part 13 is engaged with the threaded connection part 10, and an elastic washer 12 is provided at the bottom of the locking connection part 13. The elastic washer 12 is fixedly connected to the surface of the limiting anti-detachment disc 11, and the surface of the limiting anti-detachment disc 11 is slidably connected to the inner wall of the first extension rod 2.

[0026] In addition, the limiting anti-detachment disc 11 works with the inner wall of the first extension rod 2 to guide the extension and retraction of the second extension rod 3, ensuring stability after adjustment. The locking connection part 13 works with the threaded connection part 10 to lock and fix the thread. The elastic washer 12 is an auxiliary fixation to prevent loosening.

[0027] Furthermore, the fixed bracket 5 is fixedly installed at the top of the third extension rod 4, and the bottom of the fixed bracket 5 is connected to the universal module 6. The camera body 7 is movably installed on the adjustment end of the universal module 6. The inner wall of the second extension rod 3 is provided with the same structure as the threaded connection part 10, and the bottom of the third extension rod 4 is provided with the same structure as the quick-connect assembly, so that the third extension rod 4 and the second extension rod 3 are connected in cooperation. The universal module 6 is used to adjust the direction of the camera body 7.

[0028] Each extension rod has an internal assembly cavity 8 for mounting the spiral reinforcing frame 9. The spiral reinforcing frame 9 greatly enhances the resistance to bending and shearing, preventing the rod from deforming due to its own weight or wind force after extension. The camera body 7 is connected to the fixed bracket 5 via the universal module 6, which can achieve multi-degree-of-freedom adjustment to meet the monitoring needs of different orientations and angles, improving the applicability of the equipment and the monitoring coverage.

[0029] By incorporating a spiral reinforcing skeleton 9 within the first, second, and third extension rods, the overall shear resistance and bending resistance of the telescopic rod are effectively improved. Especially in its extended state, it prevents deformation caused by external forces or its own weight, ensuring the telescopic rod maintains high structural stability even after extension. The quick-connect assembly and threaded connection allow for rapid locking and releasing between the second extension rod 3 and the first extension rod 2, providing simple operation and a secure connection. The elastic washer 12 enhances the sealing and anti-loosening capabilities of the threaded connection, preventing loosening due to vibration and extending its service life.

[0030] On the other hand, this utility model proposes a reinforcement device, including an extended telescopic rod, a fixing cylinder 14 installed on the surface of the first extension rod 2, and fixing slots 21 distributed on the surface of the locking connection part 13 at the bottom end of the second extension rod 3. The fixing cylinder 14 is provided with a locking component for reinforcing the telescopic rod, and the fixing block 16 of the locking component is movably inserted into the inner wall of the fixing slot 21.

[0031] In addition, by combining the extended telescopic rod with the fixed cylinder 14, the fixed slot 21 and the locking assembly, the structural stability of the telescopic rod after extension can be further improved, effectively preventing the telescopic rod from sliding during contraction.

[0032] The locking assembly includes: a connecting baffle 17 disposed on the inner wall of the fixed cylinder 14, and a positioning shaft 18 connected to one side of the surface of the connecting baffle 17; wherein, the inner wall of the fixed cylinder 14 is provided with a limiting guide groove 15 communicating with the interior of the first extension rod 2, and the fixing block 16 is fixedly installed on the surface of the connecting baffle 17, and the two sides of the fixing block 16 are slidably connected to the inner wall of the limiting guide groove 15.

[0033] The connecting baffle 17 is a structure that connects the fixed block 16 and the positioning shaft 18, and restricts the fixed block 16. The convenient fixing spring 20 can act on the fixed block 16. The limiting guide groove 15 is used to adjust the movement of the fixed block 16, and plays a limiting and guiding role, and improves the locking effect between the fixed block 16 and the fixed groove 21.

[0034] Furthermore, a fixing spring 20 is installed inside the fixing cylinder 14. The fixing spring 20 is fitted onto the surface of the positioning shaft 18, and one end of the positioning shaft 18 is provided with an adjustment through hole 19 on the outside of the fixing cylinder 14. The fixing spring 20 can mechanically lock the position of the extension rod after it is extended and fixed, ensuring the stability of the structure. The adjustment through hole 19 is a structure that allows operators to easily adjust and control the fixing block 16, thereby facilitating the retraction and maintenance of the extension rod during inspection and maintenance.

[0035] The locking assembly within the fixed cylinder 14, in conjunction with the fixed slot, mechanically locks the telescopic rod in place after it extends. The threaded connection between the locking connector 13 and the threaded connector 10 ensures that loosening requires rotation. The mechanical locking structure of the fixed block 16 and the fixed slot 21 effectively prevents accidental retraction or slippage, ensuring the stability of the telescopic rod. The structure of the fixed spring 20 and the adjusting through-hole 19 at the end of the positioning shaft 18 further enhances the flexibility and reliability of the locking operation, improving the overall structure's resistance to wind loads and impacts.

[0036] Furthermore, the device also includes: an auxiliary module 22 mounted on a fixed bracket 5, and an illumination element mounted on the auxiliary module 22; and a monitoring module 23 mounted on the first extension rod 2, and the monitoring module 23 is communicatively connected to the auxiliary module 22 and the camera body 7.

[0037] The auxiliary module 22 uses lighting equipment, which, together with the universal module 6, enables corresponding nighttime auxiliary lighting in the area at variable angles, thereby improving the data acquisition quality and applicability of the lighting equipment. The monitoring module 23 can specifically use engineering mobile communication equipment. Both the auxiliary module 22 and the lighting equipment are equipped with extended communication interfaces. By utilizing the strong compatibility of mobile communication equipment, signal acquisition and control between multiple models of equipment can be achieved, thereby enabling inspection personnel to actively control the cargo box inspection work in multiple scenarios, thus improving inspection efficiency.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
