Description

Technical Field

[0001] This application relates to the field of telescopic pole technology, specifically a modular engineering telescopic pole assembly that can be quickly assembled and disassembled. Background Technology

[0002] In engineering operations, telescopic pole assemblies are widely used in various scenarios.

[0003] The existing engineering telescopic pole components are complicated to assemble and disassemble, requiring the use of various tools, consuming a lot of time and manpower, and reducing work efficiency; at the same time, their functions are relatively simple, making it difficult to flexibly combine and adjust them according to different engineering needs.

[0004] Therefore, this application provides a modular engineering telescopic pole assembly that can be quickly assembled and disassembled to solve the above problems. Utility Model Content

[0005] This application provides a modular engineering telescopic pole assembly that can be quickly disassembled and assembled, aiming to solve the problems mentioned in the background art, such as the complex disassembly and assembly process of existing engineering telescopic pole assemblies, the need for multiple tools, the consumption of time and manpower, and the limited functionality that makes it difficult to flexibly combine and adjust them.

[0006] To achieve the above objectives, this application provides the following technical solution: a modular engineering telescopic pole assembly that can be quickly disassembled and assembled, comprising multiple telescopic pole units, each telescopic pole unit consisting of an outer cylinder and an inner pole that moves axially within the outer cylinder, wherein the outer cylinder is provided with a fixing mechanism for fixing the relative position of the outer cylinder and the inner pole;

[0007] To improve the quick assembly and disassembly of adjacent telescopic pole units, each telescopic pole unit is equipped with a quick-connect mechanism at both ends. Adjacent telescopic pole units are detachably connected via this mechanism. The quick-connect mechanism includes a sleeve fixedly mounted at the bottom of the outer cylinder, a plug rod fixedly mounted at the top of the inner pole and inserted into the sleeve, and a fixing component for fixing the relative position of the sleeve and the plug rod. The fixing component includes a square rod slidably inserted into the top two sides of the plug rod via a through square transverse groove, a limiting groove formed within the plug rod communicating with the square transverse groove, a limiting plate slidably mounted within the limiting groove and fixedly connected to the square rod, and a spring positioned between two corresponding limiting plates within the limiting groove. Square grooves for inserting the square rod are formed on both sides of the sleeve. This quick-connect mechanism significantly improves the assembly and disassembly efficiency of the telescopic pole assembly. Adjacent telescopic pole units can be quickly disassembled by pressing the square rod; during installation, the plug rod is simply inserted into the sleeve without any tools. Compared to traditional assembly and disassembly methods, this saves considerable time and manpower, making it particularly suitable for emergency engineering operations or scenarios requiring frequent adjustments. Meanwhile, multiple telescopic pole units can be flexibly combined through a quick-connect mechanism, and the overall length can be freely changed according to actual engineering needs to meet the usage requirements of different scenarios, thereby improving the versatility and adaptability of the components.

[0008] Preferably, to facilitate insertion of the insertion rod into the sleeve, the top of the insertion rod is shaped like a frustum of a cone. This frustum-shaped design significantly reduces resistance when inserting the insertion rod into the sleeve, allowing for smoother and faster insertion. This further improves the installation efficiency of the telescopic rod unit, reduces time wasted due to alignment difficulties during installation, and also reduces the workload of operators.

[0009] Preferably, to facilitate the insertion of the square rod into the square slot, the outer end of the square rod is frustoconical. This frustoconical shape facilitates insertion of the square rod into the square slot, allowing it to slide smoothly into the slot, reducing installation difficulty, improving installation success rate and efficiency, and ensuring the stability and reliability of the telescopic rod unit connection.

[0010] Preferably, to facilitate gripping the telescopic rod unit, the outer wall of the outer cylinder is provided with anti-slip texture. The anti-slip texture on the outer wall of the outer cylinder increases the friction between the hand and the outer cylinder, making the operator's grip on the telescopic rod unit more stable and less prone to slipping. This ensures a reliable grip, especially in harsh working environments such as wet or oily conditions, improving operational safety. It also facilitates adjustment and operation of the telescopic rod unit, increasing work efficiency.

[0011] Preferably, the fixing mechanism includes a gear rotatably mounted on the top of the outer cylinder, a toothed groove vertically formed on the inner rod and meshing with the gear, a locking plate slidably inserted into the outer cylinder via a square transverse groove and engaging with the toothed groove of the gear, and a knurled bolt threaded into the outer cylinder and rotatably connected to the locking plate for driving the locking plate to move closer to or away from the gear. The design of the fixing mechanism allows for convenient and quick adjustment of the inner rod's position on the outer cylinder, and reliably fixes the relative position of the outer cylinder and the inner rod. By tightening or loosening the knurled bolt, the engagement state of the locking plate and the gear can be flexibly controlled, achieving precise adjustment and locking of the inner rod's position. This meets the precise requirements for the telescopic rod's length in different engineering scenarios, while ensuring the stability and reliability of the telescopic rod during use, avoiding any impact on the quality and safety of engineering operations due to changes in the telescopic rod's length.

[0012] This application allows for quick disassembly of adjacent telescopic pole units by pressing the square rod. During installation, the insert rod is simply inserted into the sleeve without any tools, saving significant time and manpower compared to traditional methods. This is particularly suitable for emergency engineering operations or scenarios requiring frequent adjustments. Furthermore, multiple telescopic pole units can be flexibly combined via a quick-connect mechanism, allowing for flexible adjustments to the overall length based on actual engineering needs, meeting the requirements of different scenarios and improving the versatility and adaptability of the components.

[0013] This application utilizes a fixing mechanism design that allows for convenient and quick adjustment of the inner rod's position on the outer cylinder, while reliably securing the relative positions of the outer cylinder and the inner rod. By tightening and loosening the knurled bolts, the engagement state of the locking plate and gears can be flexibly controlled, enabling precise adjustment and locking of the inner rod's position. This meets the precise length requirements of the telescopic rod in various engineering scenarios, while ensuring the stability and reliability of the telescopic rod during use, preventing changes in the telescopic rod's length from affecting the quality and safety of engineering operations.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] This embodiment provides a modular engineering telescopic pole assembly that can be quickly assembled and disassembled, such as... Figure 1-5As shown, the telescopic rod assembly includes multiple telescopic rod units 1. Each telescopic rod unit 1 consists of an outer cylinder 11 and an inner rod 12 that moves axially within the outer cylinder 11. The outer cylinder 11 is provided with a fixing mechanism 13 for fixing the relative position of the outer cylinder 11 and the inner rod 12. To improve the quick assembly and disassembly of adjacent telescopic rod units 1, quick connection mechanisms 2 are provided at both ends of the telescopic rod unit 1. Adjacent telescopic rod units 1 are detachably connected through quick connection mechanisms 2. The quick connection mechanism 2 includes a sleeve 21 fixedly disposed at the bottom of the outer cylinder 11 and a sleeve 21 fixedly disposed at the inner rod. The top of the sleeve 21 has a rod 22 that is inserted into the sleeve 21, and a fixing member 23 for fixing the relative position of the sleeve 21 and the rod 22. The fixing member 23 includes a square rod 231 that is slidably inserted into the top two sides of the rod 22 through a through square horizontal groove, a limiting groove that is opened in the rod 22 and communicates with the square horizontal groove, a limiting plate 232 that is slidably disposed in the limiting groove and fixedly connected to the square rod 231, and a spring 233 disposed between the two corresponding limiting plates 232 in the limiting groove. Square grooves 234 for the square rod 231 to be inserted are opened on both sides of the sleeve 21. The quick connection mechanism 2 greatly improves the disassembly and assembly efficiency of the telescopic rod assembly. The adjacent telescopic rod unit 1 can be quickly disassembled by pressing the square rod 231. During installation, the rod 22 can be directly inserted into the sleeve 21 without the need for any tools. Compared with the traditional disassembly and assembly method, it saves a lot of time and manpower, and is especially suitable for emergency engineering operations or frequent adjustments. Meanwhile, multiple telescopic rod units 1 can be flexibly combined through the quick-connect mechanism 2, and the overall length can be freely changed according to actual engineering needs to meet the usage requirements of different scenarios, thus improving the versatility and adaptability of the components. During disassembly, pressing the square rod 231 causes the limiting plate 232 to slide within the limiting groove, compressing the spring 233 and causing the square rod 231 to disengage from the square grooves 234 on both sides of the sleeve 21, thereby releasing the fixing of the insert rod 22 to the sleeve 21 and achieving the separation of the telescopic rod unit 1. During installation, inserting the insert rod 22 into the sleeve 21, then pressing the square rod 231 into the square horizontal groove, and continuing to push the insert rod 22, until the square rod 231 aligns with the square groove 234, causes the spring 233 to return to its original shape, pushing the limiting plate 232 and the square rod 231 into the square groove 234, completing the relative position fixing of the sleeve 21 and the insert rod 22, and achieving the quick connection of the telescopic rod unit 1.

[0023] To facilitate the insertion of the insertion rod 22 into the sleeve 21, the top of the insertion rod 22 is shaped like a frustum of a cone. This frustum-shaped design significantly reduces the resistance when the insertion rod 22 is inserted into the sleeve 21, allowing for smoother and faster insertion. This further improves the installation efficiency of the telescopic rod unit 1, reduces time wasted due to alignment difficulties during installation, and lowers the workload of the operator. The frustum-shaped top also acts as a guide; as the insertion rod 22 approaches the sleeve 21, its inclined surface guides it to accurately enter the sleeve 21. Furthermore, as the insertion rod 22 penetrates deeper, the frustum-shaped structure gradually reduces the gap between it and the inner wall of the sleeve 21, decreasing frictional resistance during insertion and allowing the insertion rod 22 to be easily inserted into the sleeve 21.

[0024] To facilitate the insertion of the square rod 231 into the square groove 234, the outer end of the square rod 231 is truncated cone-shaped. This truncated cone shape facilitates the insertion of the square rod 231 into the square groove 234, allowing it to slide smoothly into the groove, reducing installation difficulty, increasing installation success rate and efficiency, and ensuring the stability and reliability of the telescopic rod unit 1 connection. When the insert rod 22 is inserted into the sleeve 21 and pushed until the square rod 231 is close to the square groove 234, the truncated cone-shaped structure at the outer end of the square rod 231 contacts the edge of the square groove 234. As the insert rod 22 continues to be pushed, the truncated cone-shaped structure is compressed by the edge of the square groove 234, generating a component force inwards into the limiting groove, causing the square rod 231 to slide into the limiting groove. When the square rod 231 is fully aligned with the square groove 234, the spring 233 pushes the square rod 231 to quickly insert into the square groove 234 to complete the fixation.

[0025] To facilitate gripping of the telescopic rod unit 1, the outer wall of the outer cylinder 11 is provided with anti-slip textures. These textures increase the friction between the hand and the outer cylinder 11, making the operator's grip on the telescopic rod unit 1 more secure and less prone to slipping. This ensures a reliable grip, especially in harsh working environments such as wet or oily conditions, improving operational safety. It also facilitates adjustment and operation of the telescopic rod unit 1, increasing work efficiency. The anti-slip textures alter the frictional characteristics when the hand contacts the outer cylinder 11 by increasing the surface roughness. When the hand grips the outer cylinder 11, the anti-slip textures engage with the skin or glove surface, increasing the contact area and thus increasing friction. This allows the outer cylinder 11 to be stably gripped and prevents easy slippage when external force is applied to adjust or move the telescopic rod unit 1.

[0026] The fixing mechanism 13 includes a gear 131 rotatably mounted on the top of the outer cylinder 11, a toothed groove 132 vertically formed on the inner rod 12 and meshing with the gear 131, a locking plate 133 slidably inserted into the outer cylinder 11 via a square transverse groove and engaging with the toothed groove of the gear 131, and a knurled bolt 134 threaded into the outer cylinder 11 and rotatably connected to the locking plate 133 for driving the locking plate 133 to move closer to or away from the gear 131. The design of the fixing mechanism 13 makes the position adjustment of the inner rod 12 on the outer cylinder 11 convenient and quick, and reliably fixes the relative position of the outer cylinder 11 and the inner rod 12. By tightening and loosening the knurled bolt 134, the engagement state of the locking plate 133 and the gear 131 can be flexibly controlled, achieving precise adjustment and locking of the inner rod 12 position. This meets the precise requirements for the telescopic rod length in different engineering scenarios, while ensuring the stability and reliability of the telescopic rod during use, and preventing changes in the telescopic rod length from affecting the quality and safety of engineering operations. When the position of the inner rod 12 needs to be adjusted, loosen the knurled bolt 134. The knurled bolt 134 drives the locking plate 133 to move away from the gear 131, causing the locking plate 133 to disengage from the tooth groove of the gear 131. At this time, the gear 131 can rotate freely, and the tooth groove 132 on the inner rod 12 meshes with the gear 131. By moving the inner rod 12, the gear 131 is rotated, realizing the extension and retraction adjustment of the inner rod 12 within the outer cylinder 11. After adjusting to the appropriate position, tighten the knurled bolt 134. The knurled bolt 134 drives the locking plate 133 to move closer to the gear 131, causing the locking plate 133 to insert into the tooth groove of the gear 131, restricting the rotation of the gear 131, thereby fixing the relative position of the outer cylinder 11 and the inner rod 12.

[0027] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
