Abstract
The utility model discloses an industrial electrical device knob, aiming at providing the industrial electrical device knob which is fine in classification feel, long in service life and simple in structure. In order to solve the problems, the utility model adopts the technical scheme that the industrial electrical device knob comprises a knob body and a potentiometer operating rod, and is characterized in that an inner ring of the knob body is provided with a tooth groove; a clamp spring is in lap joint on the tooth groove, so that the knob body rotates to generate resistance, and the classification feel is further generated; and one end of the clamp spring is connected with a shell of a controlled object. According to the industrial electrical device knob, the tooth groove with the consistent size in the complete circumference is designed on the internal structure of the knob, the knob passes through the fixed clamp spring while rotating, and the balanced damping force is generated by the clamp spring and the tooth groove, so that the knob does not easily rotate left and right mistakenly by the external force, and the set value is not changed.
Description
Technical field
The utility model relates to a kind of knob of Industry Control electrical equipment.
Background technology
Characteristics such as Industry Control series products knob design is more and more universal, and knob structure makes product operation convenient, and data read is more directly perceived, but exist knob to be subjected to misroute about extraneous power moving easily, and the index dial that needs supporting correspondence simultaneously reads.Be subjected to misroute about extraneous power moving this defective easily at knob, as No. 200420003808.7 disclosed a kind of Knob mechanismses of Chinese patent, a kind of scheme of this Knob mechanisms is to realize damping and classification sense effect by annular contact surface being set on the knob body and jump ring being set outside annular contact surface, and another kind of scheme is to reach the steel ball and the spring that cooperate with the groove clamping in the knob body recess to realize damping and classification sense effect.The shortcoming of these two kinds of schemes is: 1: the classification sense is meticulous inadequately, owing to have only the bigger annular contact surface of setting or the groove could be by producing resistance and classification sense with jump ring or steel ball friction, therefore inapplicable knob be required on the very fine electric equipment products; 2: serviceable life is short, because the rubbing surface of jump ring or steel ball and annular contact surface or groove is very little, jump ring or steel ball are easy to the faceted pebble of annular contact surface or groove that weares and teares, thereby lose resistance and classification sense effect.3: complex structure, cost height.
The utility model content
The industrial electrical equipment knob that the technical problems to be solved in the utility model provides and provides that a kind of classification sense is meticulous, the life-span is long, simple in structure.
For addressing the above problem, the technical solution adopted in the utility model comprises knob body, potentiometer control lever, it is characterized in that: described knob body inner ring is provided with teeth groove, the overlap joint jump ring rotates the knob body and produces resistance on the described teeth groove, and producing the classification sense, described jump ring one end is connected with the housing of controlling object.
Described industrial electrical equipment knob is characterized in that: described jump ring integral body is " U " shape, and its at least one card base in upper end is outwards torn open curved, and the damping card base of formation and described teeth groove overlap joint.
Described industrial electrical equipment knob is characterized in that: described knob body lower edge is provided with one group of slip step.
Described industrial electrical equipment knob is characterized in that: be provided with one group of card base in the described knob body, described card base prolongs potentiometer control lever circumferencial direction to be arranged, and forms a back taper card post.
Described industrial electrical equipment knob is characterized in that: be provided with positioning baffle in the described knob body, the locating piece location that is provided with on the housing of the controlling object of described positioning baffle cooperates.
Described industrial electrical equipment knob is characterized in that: the housing of described controlling object is provided with the jump ring location plate washer with the jump ring location.
Described industrial electrical equipment knob is characterized in that: described knob body surface is provided with equally distributed fusiform rib broad in the middle.
The present invention has teeth groove of the same size of full week by design on the inner structure of knob, pass through a fixedly jump ring during turning knob, make jump ring and teeth groove produce deformation and produce balanced damping force, reach and do not allow to be subject to misroute about extraneous power moving, cause the change of setting value; Adopt horizontal the overlapping with teeth groove of a card base of jump ring, that teeth groove can be done is very meticulous, can also produce bigger resistance and tangible classification sense effect simultaneously; Because card base and teeth groove surface of contact are very big, can increase the serviceable life of knob greatly.Protrusion water chestnut bar shaped is in addition uniformly distributing around the top of knob, fusiform olive shape design broad in the middle, medial extremity can identify corresponding scale value, outboard end is as the scale value bearing direction, protrude resistance and feel that the rib structure has also improved necessity of holding knob greatly simultaneously, operate lighter.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1,2 is a structural representation of the present utility model;
Fig. 2 is the structural drawing of the jump ring of utility model;
Fig. 3 is the structural representation of main knob;
Fig. 4 is the synoptic diagram that is provided with of jump ring and teeth groove.
Embodiment
As shown in Figures 1 to 4, industrial electrical equipment knob of the present utility model, comprise knob body 1, potentiometer control lever 2, described knob body 1 inner ring is provided with teeth groove 3, overlap joint jump ring 4 rotates knob body 1 and produces resistance on the described teeth groove 3, and produce the classification sense, be attached thereto in the position, hole 14 of the housing 5 of the end insertion controlling object of described jump ring 4.Described jump ring 4 integral body are " U " shape, and its at least one card base in upper end is outwards torn open curved, and the damping card base 6 of formation and described teeth groove 3 overlap joints.
Knob body of the present invention 1 lower edge is provided with and is evenly distributed three slip steps 7, and surface of contact was littler when the design by the slip step was rotated knob on panel, and each angle resistance is balanced more simultaneously; Be provided with one group of card base 8 in the described knob body 1, described card base 8 prolongs potentiometer control lever 2 circumferencial directions to be arranged, and forms a back taper card post, with knob window 13 clampings on the housing 5 of controlling object, the installation knob that can very conveniently put in place; Be provided with positioning baffle 9 in the described knob body 1, locating piece 10 location that are provided with on the housing 5 of the controlling object of described positioning baffle 9 cooperate, and make put in place the maximum angle scope of an appointment of knob energy of rotation; The housing 1 of described controlling object is provided with the jump ring location plate washer 11 with jump ring 4 location, when jump ring one end is inserted in the position, hole 14 of housing 5 of controlling object, an other end cooperates with jump ring location plate washer 11 gears, and spring location plate washer carries out the amplitude location to jump ring when swinging; Described knob body 1 surface is provided with equally distributed fusiform rib 12 broad in the middle.
