Enter, and inconvenient alignment, it is troublesome in poeration.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of music stand telescopic rod proposed
Anti-taking off structure.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of music stand telescopic rod anti-taking off structure, including small aluminum pipe, big aluminum pipe and sleeve, which is characterized in that the small aluminium
The outer wall of one end of pipe and the big aluminum pipe is socketed on the inner wall of the sleeve vertically, and the side wall of the sleeve is provided with fastening
The inner wall of swivel nut, the fastening swivel nut is socketed with pre-buried copper nut.
Preferably, the small aluminum pipe, the big aluminum pipe and the sleeve central axes are straight line.
Preferably, the side wall of the sleeve offers antiskid groove.
Preferably, the inner wall of the sleeve is provided with rubber connecting sleeve, sealing bush, anti-avulsion set and bushing.
Preferably, the bushing is placed between the anti-avulsion set and the rubber connecting sleeve.
Preferably, the inner thread of the pre-buried copper nut is connected with bolt, and the side wall of the bolt offers screw thread, institute
It states bolt and is fixedly connected with rubber head screw far from one end of the pre-buried copper nut.
Compared with prior art, the utility model proposes a kind of music stand telescopic rod anti-taking off structure, have beneficial below
Effect:
The utility model will be used to prevent tubule from thoroughly pulling out when up stretching out, reduce maloperation bring realign it is slotting
The inconvenience entered is mainly used for inside music stand telescopic rod, prevents tubule from deviating from from big pipe when adjusting height.
The utility model will release a kind of telescopic rod anti-drop device of music easel, including small aluminum pipe, big aluminum pipe and sleeve,
The outer wall of one end of small aluminum pipe and the big aluminum pipe is socketed on the inner wall of sleeve vertically, and the side wall of sleeve is provided with fastening spiral shell
Set, the inner wall for fastening swivel nut are socketed with pre-buried copper nut.
The utility model is first fixed on small by increasing structure anti-avulsion set and bushing, anti-avulsion set on the basis of ordinary construction
Aluminum pipe lower end, bushing are initially charged with rubber connecting sleeve before filling big aluminum pipe, are then charged into big aluminum pipe and fixation；Finally lower end is filled
The small aluminum pipe for having anti-avulsion to cover penetrates；In this way when small aluminum pipe is toward when pulling up, lower end cannot pass through bushing with the anti-avulsion set of boss, then can
It prevents from.
In the utility model, it is not directed to part in the device and is the same as those in the prior art or can be used the prior art and be subject to reality
Existing, the utility model structure is simple, and it is convenient to operate, and is suitble to large-scale advocate to use, practical effect with higher.
