Description

Telescopic rod steering joint for heavy load

This creation is related to the steering joints of telescopic rods, especially the steering joints of telescopic rods with high loads.

When playing musical instruments or stage performances, a variety of musical instruments and acousto-optic equipment are required to support musical instruments, lighting equipment, etc., to provide lighting or special effects. For example, a holder disclosed in the US Patent No. US 9,633,635 B2, used with a support tube, can be used to fix various cymbals, drums, cow bells, etc., as well as musical scores required for performance, so that cymbals, drums, Cow bells, etc. and music scores are set beside the performer.

Different performers have different habits and hobbies, so they need to place the music scores, musical instruments, sound and light and other equipment at the position and angle of personal habit. It is known to use one of the rotating joints as disclosed in the US bulletin US 9,310,021 B2 The rotary joint has a lower joint and an upper joint. The upper and lower joints can be respectively connected to a rod. After a tightening knob of the rotary joint is loosened by turning, the upper and lower joints can be separated to change the upper , The relative angle of the lower joint is used to adjust the relative inclination angle of the two rods, so the equipment installed on the rods can be adjusted to the required placement angle.

However, in the conventional rotary joint, the pivot point of the upper and lower joints and the locking point of the tightening knob are at the same position. Therefore, when the weight of the device provided on the rod is heavy, the The tightening of the knob will bear considerable torque and may loosen. Therefore, the upper and lower joints must have a zigzag anti-slip structure corresponding to the engagement, which leads to the problem of the minimum adjustment angle when adjusting the angle, and it is easy to have the problem of tooth shape collapse and loosening and unable to correspond to the engagement. .

In this context, the main purpose of this creation is to expose a telescopic rod steering joint that can meet the requirements of stepless adjustment and high load.

To achieve the above purpose, this creation provides a telescopic rod steering joint for connecting a bottom tube and a support tube. The telescopic rod steering joint includes a base, a support base and a locking member, wherein the base includes a clamped bottom The first clamp of the tube and a first pivot plate, the first pivot plate has a guide groove, the support base has a second clamp for clamping the support tube and a second pivot plate, the second pivot The connecting plate has a through hole. The first pivoting plate and the second pivoting plate are pivotally connected together at a pivot point, and when the first pivoting plate and the second pivoting plate are relatively rotated, the through hole is Keep facing the guide groove, the locking member passes through the through hole and the guide groove and clamps and fixes the first pivot plate and the second pivot plate so that the first pivot plate and the second pivot plate Can not rotate relative to each other.

Accordingly, the base and the support base of the present creation are respectively connected to the bottom tube and the support tube, and the base and the support base can be relatively rotated through the pivotal connection of the first pivot plate and the second pivot plate , So the support tube can be adjusted arbitrarily with the required angle. In addition, the clamping and fixing positions of the pivot point and the locking element are different, so there is a certain distance between the pivoting point and the clamping and fixing position of the locking element. Compared with the prior art, the pivot point is the clamping and fixing position. The telescopic rod steering joint can have a higher load carrying capacity, that is, the support tube can be hung with heavier equipment without the doubt of slippage, and meet the needs of high load.
