Description

Technical Field

[0001] The utility model relates to the technical field of telescopic rods, and specifically relates to an improved telescopic rod structure. Background Art

[0002] A telescopic rod is a device that can manually adjust the overall length of the rod according to actual needs, and is widely used in real life, such as mop rods, clothes drying rods, and broom rods, etc. However, when the existing telescopic rod is actually used, it mainly realizes the positioning function by clamping the outer wall of the main pipe with a locking piece. However, due to the certain elasticity of the overall structure, the overall stability of the telescopic rod is poor after clamping, and problems such as easy sliding are likely to occur. Therefore, in view of the above problems, an improved telescopic rod structure is designed to better meet the actual use requirements. Summary of the Invention

[0003] The purpose of the utility model is to provide an improved telescopic rod structure to solve the problems of easy slipping from the hand, poor waterproof performance, and inconvenient use mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an improved telescopic rod structure, including a main pipe body, a locking piece is connected to the upper end of the main pipe body, the main pipe body is connected to a telescopic pipe, a tightening and loosening adjusting piece is slidably connected to the telescopic pipe, a limiting piece is fixedly connected to the lower end of the telescopic pipe in a clamping manner, and a screw thread connection is provided between the limiting piece and the friction fastening piece.

[0005] Preferably, a grip is nested and connected to the lower end of the main pipe body, and anti-slip lines are arranged on the surface of the grip. Through the function of the grip, it is convenient for the user to hold and use the telescopic rod.

[0006] Preferably, an elastic piece is further fixed on the locking piece, and the inner wall of the elastic piece contacts the telescopic pipe to realize the locking function. Through the function of the elastic piece, it can ensure that the elastic piece is locked with the telescopic pipe.

[0007] Preferably, the locking piece and the main pipe body are nested and connected, and the elastic piece and the tightening and loosening adjusting piece are threadedly connected. Through the threaded connection between the elastic piece and the tightening and loosening adjusting piece, it can provide a basic guarantee for the adjustment of the elastic piece.

[0008] Preferably, the telescopic pipe passes through the locking piece and can slide, and the length of the telescopic pipe is less than the length of the main pipe body. Through the sliding between the telescopic pipe and the locking piece, it can provide a basic guarantee for the length adjustment of the telescopic rod.

[0009] Preferably, a connecting piece is nested and connected to the upper end of the telescopic pipe. Through the connecting piece, it is convenient to install and fix external parts.

[0010] Preferably, the limiting member is slidably connected to the main pipe body, and the lower end of the limiting member is a conical structure. Through the sliding action between the limiting member and the main pipe body, the normal adjustment of the length of the telescopic rod can be ensured.

[0011] Preferably, the friction fastener can achieve a fastening effect when contacting the inner wall of the main pipe body, and the friction fastener has elasticity. Through the fastening effect achieved by the contact between the friction fastener and the inner wall of the main pipe body, an inner support locking and fixing effect can be achieved, further ensuring the stability of the telescopic rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this improved telescopic rod structure, the external friction fastening mechanism and the inner support friction fastening mechanism can achieve the dual locking effects of the main pipe body and the telescopic pipe, thereby effectively ensuring the stability after the length adjustment of the telescopic rod. Moreover, through the dual fastening mechanism, the situation where the telescopic rod is not stably locked due to the elasticity of the main pipe body itself can be effectively avoided, thus better meeting the actual use requirements.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: An improved telescopic rod structure, including a main pipe body 1, a locking member 3 is connected to the upper end of the main pipe body 1, the main pipe body 1 is connected to the telescopic pipe 4, a tension adjustment member 6 is slidably connected to the telescopic pipe 4, a limiting member 7 is snap-fitted and fixedly connected to the lower end of the telescopic pipe 4, and a screw thread connection is provided between the limiting member 7 and the friction fastener 8.

[0019] The lower end of the main body 1 is nested with a handle 2, and the surface of the handle 2 is provided with anti-slip grooves; an elastic sheet 301 is also fixed to the locking member 3, and the inner wall of the elastic sheet 301 contacts the telescopic tube 4 to achieve a locking effect, and the elastic sheet 301 has a conical structure; the locking member 3 and the main body 1 are nested, and the elastic sheet 301 and the tension adjustment member 6 are threaded; the telescopic tube 4 passes through the locking member 3 and can slide, and the length of the telescopic tube 4 is less than the length of the main body 1; the upper end of the telescopic tube 4 is nested with a connecting member 5; the limit member 7 and the main body 1 are slidably connected, and the lower end of the limit member 7 is a tapered structure; the friction fastener 8 contacts the inner wall of the main body 1 to achieve a tightening effect, and the friction fastener 8 is elastic;

[0020] When using the improved telescopic rod structure, Figures 1 - 3 As shown, the connecting member 5 can facilitate the installation of functional parts (such as mop heads and broom heads, etc.), and the function of the handle 2 can make it convenient to hold and use the device. In actual use, when it is necessary to adjust the length of the telescopic rod, the lock between the elastic sheet 301 and the telescopic tube 4 can be released by loosening the tension adjusting member 6, and then the telescopic tube 4 can be rotated to drive the limit member 7 to rotate, thereby releasing the lock between the friction fastener 8 and the main body 1. At this time, the length of the entire telescopic rod can be adjusted by the sliding action between the telescopic tube 4 and the locking member 3. After adjusting to the appropriate position, the limit member 7 can be rotated by rotating the telescopic tube 4. , in conjunction with the conical structure of the limiter 7 and the elastic action of the friction fastener 8 itself, the friction fastener 8 can be stretched so that the friction fastener 8 is in close contact with the inner wall of the main body 1, thereby realizing the internal support locking effect, and then by rotating the tension adjustment member 6, in conjunction with the threaded connection between the tension adjustment member 6 and the elastic sheet 301, the elastic sheet 301 can be in close contact with the outer wall of the telescopic tube 4, thereby realizing the external clamping fastening effect. In summary, through the dual fastening mechanism of internal support and external clamping, the stability of the connection between the main body 1 and the telescopic tube 4 can be effectively guaranteed, thereby effectively avoiding the occurrence of loosening. This is the working principle of the improved telescopic rod structure.
