Problems solved by technology
[0003] Agricultural machinery is different from home appliances. Most agricultural machinery is accompanied by a large amount of mechanical vibration during the working process. If the connection between the knob and the agricultural machinery casing is too tight, it cannot rotate flexibly; if the connection between the knob and the agricultural machinery casing is loose, the knob is easily affected by mechanical vibration. and come off the case

Embodiment Construction
[0017] The present invention will be described in further detail below by means of specific embodiments:
[0018] The reference signs in the drawings of the specification include: positioning sleeve 20, avoidance groove 45, inner wall 26, slider 42, gear protrusion 41, gear assembly 40, spline 11, handle 15, middle sleeve 10, spline groove 31 , long board 30
[0019] This embodiment is basically as attached figure 1 As shown: the installation mechanism of the agricultural machine casing knob in this embodiment, including the knob body. The splines 11 and the circumferential annular grooves are sequentially arranged on the middle casing 10 from top to bottom; the outer diameters of the handle 15, the splines 11 and the circumferential annular grooves are successively reduced.
[0020] Such as figure 2 As shown, the installation mechanism of the agricultural machine casing knob in this embodiment also includes a mounting plate, and the mounting plate includes two elongated p...

The invention discloses a rotary knob mounting mechanism, and specifically to an agricultural machinery case rotary knob mounting mechanism. The agricultural machinery case rotary knob mounting mechanism comprises a rotary knob body and a mounting plate; the rotary knob body comprises a positioning sleeve, and a handle, a middle sleeve pipe, splines and a circumferential annular groove that are integrally molded; the handle, the splines and the circumferential annular groove are arranged on the middle sleeve pipe from upper to lower in sequence; the mounting plate comprises two long-strip-shaped plates that are butted up and down; spline grooves matched with the shape of the splines are formed in the two long-strip-shaped plates; the circumferential annular groove is sleeved with the positioning sleeve; a sliding block that is embedded into the circumferential annular groove and glidingly connected with the circumferential annular groove is arranged in the positioning sleeve; the splines are embedded into the two long-strip-shaped spline grooves; and the two long-strip-shaped plates are clamped between the handle and the positing sleeve. The shortcoming that the rotary knob is easy to loose in the prior art is overcome by the rotary knob mounting mechanism provided by the invention; and the rotary knob mounting mechanism can realize stable connection between the rotary knob and the agricultural machinery case on the premise of ensuring flexible rotation of the rotary knob.
Description
technical field [0001] The invention relates to a knob installation mechanism, in particular to a knob installation mechanism for an agricultural machine casing. Background technique [0002] Many home appliances on the market (such as electric kettles, ovens, microwave ovens, toasters, etc.) all use knob control structures to control electronic devices to work. In the prior art, the knob structure usually directly sets the connecting shaft at the center of the knob body, thereby controlling the potentiometer (such as: in the field of electric kettles, the knob structure is usually used to control the potentiometer so as to keep the boiling water warm and make the boiling water Keep it at a certain temperature; in the fields of ovens, microwave ovens, and toasters, the heating time of food is usually controlled by controlling the potentiometer). As applied on May 18, 2004, the patent number is: ZL2004200461160, a Chinese invention patent for a toaster electronic timer, incl...
