Abstract
A knob structure for an Lugong-shaped constant-temperature reset-type temperature controller comprises a knob shaft, an indicating plate and a planar cam, wherein an end cover is arranged at the upper end of the planar cam, and a wave-shaped ring is arranged at the upper end of the end cover; the indicating plate suit is epaxial at the knob, and formula structure as an organic whole is fixed between indicating plate and the knob axle, the lower extreme of knob axle is installed in the plane cam. The utility model discloses a make integral type structure with knob axle and indicator board, the assembly of being convenient for has improved the precision of knob axle and cam riveting angle to improve work efficiency.
Description
Technical Field
The utility model relates to a knob structure for an aigrette-shaped constant-temperature reset-type temperature controller.
Background
At present, the lu type pressure type constant temperature reset type temperature controller is widely applied to the temperature control of household appliances such as refrigerators, the knob structure that the existing lu type pressure type constant temperature reset type temperature controller is used comprises a knob shaft, an indicating plate, a wave ring, a cover and a plane cam, and because the constant temperature reset type temperature controller is provided with a plurality of parts and is complex to assemble, the assembly efficiency is low, the knob shaft and the indicating plate are of a separated structure, and the precision of riveting angles of the knob shaft and the cam is hardly guaranteed after the knob shaft and the indicating plate are installed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a knob structure for an aigrette-shaped constant-temperature reset temperature controller to solve the problems in the background technology.
The technical scheme adopted for achieving the purpose is that the knob structure for the Lugong-shaped constant-temperature reset-type temperature controller comprises a knob shaft, an indicating plate and a plane cam, wherein the upper end of the plane cam is provided with an end cover, and the upper end of the end cover is provided with a wave-shaped ring; the indicating plate suit is epaxial at the knob, and formula structure as an organic whole is fixed between indicating plate and the knob axle, the lower extreme of knob axle is installed in the plane cam.
Advantageous effects
Compared with the prior art, the utility model has the following advantages.
The utility model has the advantages that, this structure establishes indicator board and knob axle to the integral type structure, makes it reduce installation steps in assembling process, has reduced the time of putting the indicator board when the riveting, has guaranteed the precision of knob axle with cam riveting angle simultaneously, has improved the operating efficiency.
Drawings
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the following embodiments and the accompanying drawings.
A knob structure for an Lugong-type constant-temperature reset-type temperature controller is shown in figure 1 and comprises a knob shaft 1, an indicating plate 2 and a plane cam 5, wherein an end cover 4 is arranged at the upper end of the plane cam 5, and a wave-shaped ring 3 is arranged at the upper end of the end cover 4; indicator board 2 suit is on knob axle 1, and formula structure as an organic whole is fixed between indicator board 2 and the knob axle 1, install in planar cam 5 the lower extreme of knob axle 1.
The indicating plate 2 and the knob shaft 1 are fixed in an integrated structure, and the indicating plate 2 and the knob shaft 1 are in tight fit connection and welding connection between hole shafts, or the indicating plate 2 and the knob shaft 1 are integrally manufactured.
The utility model discloses when concrete implementation, put planar cam 5, end cover 4, wave form circle 3 on the lower mould in proper order, put knob axle 1 that has the integral type structure indicator board 2 again in the upper die to make the lower extreme installation of knob axle 1 fix in planar cam 5. Because indicator panel 2 and knob axle 1 make into integral type structure, when the apron riveting, put a part less, the riveting of being convenient for, and can improve the angle precision of knob axle 1 after the riveting.
