Abstract
The utility model relates to a pneumatic lifting bar which is used in lifting chair and so on, comprising a pneumatic mandrel, an outer sleeve encapsulated the pneumatic mandrel, and a guiding sleeve disposed between the pneumatic mandrel and the outer sleeve. A positioning sleeve which is sealed and sleeved on the outer surface of the pneumatic mandrel is arranged between the pneumatic mandrel and the guiding sleeve, the outer surface of the positioning sleeve is stuck up with a rib which is extended along the length direction of the positioning sleeve, the corresponding guiding sleeve wall is provided with a groove meshed with the rib. The utility model is reasonable and simple in structure design, and convenient in use.
Description
(1) technical field
The utility model relates to a kind of Pneumatic elevation bar of using as the lifting chair class.
(2) background technique
Present lifting chair can be regulated highly again and can rotate, and is very suitable, but some occasion only use need to regulate and highly do not need the chair that rotates, also have computer desk sometimes according to using needs also as long as can regulate highly not needs rotation.
(3) summary of the invention
Therefore, the purpose of this utility model is to provide a kind of and can only regulates the Pneumatic elevation bar that height can not rotate.
The purpose of this utility model is to realize like this.
A kind of Pneumatic elevation bar, the overcoat and the guide pin bushing between pneumatic plug and overcoat that comprise pneumatic plug, the pneumatic plug of parcel, between pneumatic plug and guide pin bushing, also be provided with a close abutment sleeve that is enclosed within pneumatic mandrel outer surface, the outer surface upper process of abutment sleeve has the rib that extends along the abutment sleeve length direction, has the groove of engagement rib on the corresponding guide pin bushing wall.
The purpose of this utility model also can further realize by following technical proposals.
The lower end of pneumatic plug is inwardly shunk and is formed a circle reducing, and the pneumatic mandrel outer surface of reducing top is provided with a circle ratchet, the corresponding also inwardly shrink wrapped reducing of the not end of abutment sleeve.It is tightr that abutment sleeve is cooperated with pneumatic plug, makes and can not rotate mutually between pneumatic plug and the abutment sleeve.
The outer surface upper edge guide pin bushing length direction spaced protrusions of guide pin bushing has several ribs, and the outer surface of rib is against the internal surface of overcoat.
The utility model reasonable in design is simple, and is easy to use.
