Abstract
The utility model relates to a handle self -modulation music stand for the music book supports, and it discloses the connecting rod, connect, and the conditioning controller, the spring, the clamping piece, the push jack, the conditioning controller, the telescopic link, connect, a spring, end section partially insert that the push jack connected gradually installation back telescopic link from top to bottom is to the stay tube of supporting legs in, pressing on the handle of conditioning controller is deducted to the one end of connecting rod, the other end passes the telescopic link in proper order, connect, a spring, the push jack is at the bottom of push jack protrusion, the protrusion end of connecting rod bottom is connected with the nut through the screw thread, the both sides that lie in the push jack on connecting are provided with the clamping piece respectively, the one end of two clamping pieces is articulated with the joint respectively, the push jack be a trapezoidal push jack, enable two clamping pieces when the push jack moves down and launch to left and right both sides. The utility model has the advantages that it adopts the push type to adjust the telescopic link, can nimble conveniently adjust the elevating of music book platform, and it is convenient to adjust moreover, does not have the smooth silk or the not hard up phenomenon of the screw formula of adjusting.
Description
Technical field
This utility model is related to handle self-regulated music easel, and specifically a kind of pressing type adjusts the music easel of height.
Background technology
The regulative mode of traditional staff frame is all to twist by screw to be fixed or to adjust height, the holding of this mode
Gravity is good, but the troublesome poeration when adjusting, and stripped thread or loosening phenomenon occur after long-term use, and the height adjusting
Low underaction is convenient.
Utility model content
The purpose of this utility model is to provide a kind of handle self-regulated music easel, and it adopts pressing type adjustable telescopic rod, can spirit
Work is conveniently adjusted the high bottom of music stand, and easy to adjust, there is not the stripped thread of screw regulation formula or loosening phenomenon.
Technical solution of the present utility model is the support feet in music stand, on the basis of expansion link, the company of being characterized in
Bar, joint, adjust controller, spring, intermediate plate, push jack, described regulation controller, expansion link, joint, spring, push jack are by upper
To under be sequentially connected install rear telescopic rod a bottom section part be inserted into support feet support tube in, regulation is deducted in one end of connecting rod
On the press handle of controller, the other end sequentially passes through expansion link, joint, spring, push jack in the bottom of push jack protrusion, connecting rod bottom
Protruding end be connected with nut by screw thread, on joint be located at push jack both sides be respectively arranged with intermediate plate, two pieces of intermediate plates
One end is hinged with joint respectively；Described push jack is one piece of trapezoidal push jack, can make when push jack moves down two pieces of intermediate plates to the left,
Right both sides are launched.
Operation principle of the present utility model be when the press handle of the lower regulation controller of pressing by connecting rod drive push jack to
Upper movement forces spring-compressed so that intermediate plate disappears to both sides expansion support force, the now freely adjustable collapsing length of expansion link,
When unclamping press handle, spring reset drive push jack moves down and forces two intermediate plates to launch to both sides thus fixing expansion link.
The utility model has the advantages that it adopts pressing type adjustable telescopic rod, can flexibly and easily adjust the height of music stand
Bottom, and easy to adjust, there is not the stripped thread of screw regulation formula or loosening phenomenon.
