Description

Technical Field

[0001] This utility model relates to the field of telescopic rod technology, and more specifically, to a telescopic rod structure with anti-detachment locking mechanism. Background Technology

[0002] A telescopic rod is a rod-shaped structure that can be adjusted in length. Its core feature is that it can freely extend or shorten within a certain length range. It has a wide range of uses, such as curtain rods, clothes racks, and light fixtures.

[0003] Telescopic poles typically consist of two parts: an inner pole and an outer pole. These two parts can slide back and forth. When the poles reach the desired length, they need to be locked in place. Existing telescopic poles usually use clamps or clips as locking mechanisms. These clamps or clips compress the inner pole, creating friction and limiting its relative sliding with the outer pole. However, telescopic poles made of plastic or metal often have smooth surfaces, and over time, the clamps or clips can wear down against the outer pole, resulting in poor locking and causing the telescopic pole to slip during use. Utility Model Content

[0004] This utility model provides an anti-loosening locking telescopic rod structure, which solves the technical problem that the existing telescopic rods usually use clamps or clips as locking structures, resulting in poor locking effect on the rods.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A locking telescopic rod structure includes an inner rod and an outer rod. The front end of the outer rod is provided with a locking part. Several sets of threaded sleeves are rotatably connected to the locking part. The several sets of threaded sleeves are equidistantly distributed around the locking part. Each threaded sleeve is threaded with a screw. An adjusting sleeve is rotatably provided on the outer rod at the position where it intersects with the locking part. A synchronous drive assembly for controlling the simultaneous rotation of the several sets of threaded sleeves is provided between the adjusting sleeve and the several sets of threaded sleeves. One end of the screw extends into the interior of the locking part and is fixedly connected to a locking plate. The surface of the locking plate is provided with a first tooth pattern. The surface of the inner rod is provided with a second tooth pattern corresponding to the first tooth pattern.

[0007] Furthermore, the synchronous drive assembly includes a bevel gear ring disposed at the front end of the adjusting sleeve and bevel gears sleeved on the surfaces of several sets of threaded sleeves, wherein the bevel gear ring and the bevel gears mesh with each other.

[0008] Furthermore, a guide hole is fixedly provided on the locking part, and a guide slide rod is slidably connected inside the guide hole. One end of the guide slide rod extends into the inner side of the locking part and is fixedly connected to the locking piece.

[0009] Furthermore, the outer surface of the adjusting sleeve is provided with anti-slip texture.

[0010] Furthermore, a slide bar is provided on the inner wall of the outer rod, and a groove is provided on the outer surface of the inner rod to fit the slide bar.

[0011] Furthermore, the inner rod and the outer rod are made of metal, and the cross-section of both the inner rod and the outer rod is circular.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by rotating the adjusting sleeve, several sets of threaded sleeves can rotate synchronously under the action of the synchronous drive component. During this process, the screws threaded in the several sets of threaded sleeves will drive the locking plates to move simultaneously toward the inner or outer side of the locking part. When the several sets of locking plates are controlled to move simultaneously toward the inner side of the locking part, the several sets of locking plates will abut against the surface of the inner rod from multiple directions. At this time, the first and second teeth between the locking plates and the inner rod will mesh together. The first and second teeth meshing together from multiple directions can restrict the relative sliding between the inner rod and the outer rod, effectively preventing the inner rod and the outer rod from slipping under a large tensile force, and ensuring reliable locking between the two.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4A locking telescopic rod structure includes an inner rod 1 and an outer rod 2. The inner rod 1 and the outer rod 2 have matching inner cavity contours. The inner rod 1 can slide back and forth inside the outer rod 2. A locking part 3 is provided at the front end of the outer rod 2. Several sets of threaded sleeves 4 are provided on the locking part 3. The several sets of threaded sleeves 4 are equidistantly distributed around the locking part 3 and rotatably connected to the locking part 3. Each threaded sleeve 4 is threaded with a screw 5. An adjusting sleeve 9 is rotatably provided at the position where the outer rod 2 intersects with the locking part 3. A synchronous drive assembly is provided between the adjusting sleeve 9 and the several sets of threaded sleeves 4. When the adjusting sleeve 9 is rotated, the synchronous drive assembly can control the several sets of threaded sleeves 4 to rotate simultaneously. One end of the screw 5 extends into the interior of the locking part 3 and is fixedly connected to a locking plate 6. When the threaded sleeves 4 are opposite to each other... When the screw 5 rotates, it will be driven by the screw sleeve 4 to move towards the inside or outside of the locking part 3. Since the locking part 3 at the front end of the outer rod 2 is nested on the outside of the inner rod 1, the locking plate 6 will move towards the side closer to or away from the inner rod 1 under the drive of the screw 5. The surface of the locking plate 6 is provided with a first tooth 7, and the surface of the inner rod 1 is provided with a second tooth 8 corresponding to the first tooth 7. When the locking plate 6 and the surface of the inner rod 1 come into contact with each other, the first tooth 7 and the second tooth 8 between them will mesh together. At this time, the inner rod 1 and the outer rod 2 will not be able to slide relative to each other under the restriction of the first tooth 7 and the second tooth 8, thereby locking and fixing the inner rod 1 and the outer rod 2.

[0022] In use, the extension length of the inner rod 1 is controlled by sliding the inner rod 1 back and forth inside the outer rod 2. By rotating the adjusting sleeve 9, several sets of threaded sleeves 4 can rotate synchronously under the action of the synchronous drive assembly. During this process, the screw 5 threaded in the several sets of threaded sleeves 4 will drive the locking plates 6 to move simultaneously toward the inside or outside of the locking part 3. When the several sets of locking plates 6 are controlled to move simultaneously toward the inside of the locking part 3, the several sets of locking plates 6 will abut against the surface of the inner rod 1 from multiple directions. At this time, the first tooth 7 and the second tooth 8 between the locking plates 6 and the inner rod 1 will mesh together, interlocking from multiple directions. The first tooth 7 and the second tooth 8, when combined, can restrict the relative sliding between the inner rod 1 and the outer rod 2, effectively preventing slippage between the inner rod 1 and the outer rod 2 under large tensile force, and ensuring reliable locking between the two. In addition, when the adjusting sleeve 9 is rotated to control several sets of locking plates 6 to move outwards from the locking part 3, the several sets of locking plates 6 will separate from the inner rod 1, so that the sliding of the inner rod 1 inside the outer rod 2 is no longer restricted. At this time, the locking state between the inner rod 1 and the outer rod 2 can be released, allowing the inner rod 1 to slide back and forth inside the outer rod 2.

[0023] For further details, please refer to Figure 1-4The synchronous drive assembly includes a bevel ring 10 disposed at the front end of the adjusting sleeve 9 and bevel gears 11 sleeved on the surfaces of several sets of threaded sleeves 4. The bevel ring 10 and the bevel gears 11 mesh with each other. When the adjusting sleeve 9 is rotated, the bevel ring 10 can rotate under the drive of the adjusting sleeve 9. At this time, under the meshing transmission action of the bevel ring 10 and the bevel gears 11, several sets of threaded sleeves 4 can be driven to rotate synchronously.

[0024] For further details, please refer to Figure 1-4 A guide hole 12 is fixedly provided on the locking part 3. A guide slide rod 13 is slidably connected inside the guide hole 12. One end of the guide slide rod 13 extends into the inner side of the locking part 3 and is fixedly connected to the locking piece 6. When the locking piece 6 is driven to move by controlling the rotation of the screw sleeve 4, the locking piece 6 can drive the guide slide rod 13 to slide along the guide hole 12. At this time, the guide hole 12 and the guide slide rod 13 can guide the movement of the locking piece 6, ensuring that the locking piece 6 can move stably towards the inner or outer side of the locking part 3 without deflecting as the screw sleeve 4 rotates.

[0025] For further details, please refer to Figure 1-4 The outer surface of the adjusting sleeve 9 is provided with anti-slip texture 14. When the user rotates the adjusting sleeve 9, the anti-slip texture 14 can increase the frictional resistance between the user's hand and the adjusting sleeve 9, thereby making it easier to control the rotation of the adjusting sleeve 9 and preventing the hand from slipping when rotating the adjusting sleeve 9.

[0026] For further details, please refer to Figure 1-4 The inner wall of the outer rod 2 is provided with a slide bar 15, and the outer surface of the inner rod 1 is provided with a slide groove 16 that fits with the slide bar 15. The mutually fitting slide bar 15 and slide groove 16 can restrict the relative rotation between the inner rod 1 and the outer rod 2. Therefore, it can prevent the inner rod 1 and the outer rod 2 from rotating relative to each other while they are sliding, so that the first tooth 7 and the second tooth 8 between the locking piece 6 and the inner rod 1 can always remain aligned.

[0027] For further details, please refer to Figure 1-4 The inner rod 1 and the outer rod 2 are made of metal materials, preferably stainless steel, which have high strength and corrosion resistance, effectively ensuring the service life of the structure. Both of them have circular cross sections, which makes the stress performance of the inner rod 1 and the outer rod 2 uniform in all directions, further ensuring the bending strength of the structure and making it less prone to bending deformation under load.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
