technical field

The invention relates to the technical field of telescopic rods, in particular to a clip-connected telescopic rod.

Background technique

In the existing technology, for mechanical connection equipment, the telescopic action is mainly completed by the pneumatic mechanism. In some parts that only need transmission and no load-bearing, this type of pneumatic mechanism is more convenient. However, in some special application scenarios, For example, the spreader requires the telescopic rod to have load-bearing capacity, but due to the large moment and certain shear force, the telescopic rod often causes sliding, falling off and mechanical damage.

The end of the body rod is provided with a tightening part, and the tightening part is fixedly connected with a snap-in part. The length of the clamping part is greater than the difference between the outer diameter of the body rod and the outer diameter of the tightening part, the connecting rod is a hollow structure, and the inner diameter of the connecting rod is not smaller than the outer diameter of the tightening part and Not larger than the outer diameter of the body rod, the rod wall of the connecting rod is provided with a transverse groove running through the length direction of the connecting rod, and the transverse groove is connected with a plurality of longitudinal grooves, each of the longitudinal grooves The inner walls on both sides of the tank body are provided with clamping plates rotatably connected to the inner wall of the tank. There is a gap between the two clamping plates, and the width of the gap is smaller than the outer diameter of the clamping part. The clamping plate A spring is connected between the bottom of the longitudinal groove, the width of the longitudinal groove is consistent with the outer diameter of the clamping part, and the width of the transverse groove is not smaller than the width of the longitudinal groove.

Preferably, the longitudinal grooves are equidistantly distributed.

Preferably, the clamping plates in the longitudinal grooves are located at the same horizontal position.

Based on the disclosure of the above technical solutions, compared with the prior art, the present invention sequentially connects the main body rod and the connecting rod during the connection process, and extends the tightening part of the main body rod into the inner cavity of the connecting rod, wherein the clamping part of the main body rod The connecting part is aligned with the transverse groove of the connecting rod. When the main body rod moves to a predetermined position, the main body rod is rotated, and the clamping part of the main body rod is inserted into the longitudinal groove of the connecting rod through the clamping plate of the connecting rod. Next, the clamping plate of the connecting rod locks the clamping part of the main body rod in the longitudinal groove of the connecting rod, thus completing the connection between the main body rod and the connecting rod to form a telescopic rod. This connection method enables the telescopic rod to withstand moments in all directions , at the same time, the length of the telescopic rod can be adjusted by making the locking part of the body rod locked in different longitudinal grooves of the connecting rod.
