Abstract

The utility model discloses a marching type knob device which comprises a fixed cylinder seat and a knob shaft, wherein the inner wall of the fixed cylinder seat is provided with multiple stages of concaves along the circumference direction, the fixed cylinder seat is matched with the knob shaft in a buckling manner, more than one elastic clamping arm extends from the bottom of the knob shaft and extends into the fixed cylinder seat, bulges matched with the concaves on the inner wall of the fixed cylinder seat are arranged on the outer side wall of the clamping arm, and a barb is formed at the tail end of the clamping arm and clamps the bottom surface of the fixed cylinder seat. After subjected to the structure improvement, the matching type knob device only needs two accessories, and has the advantages of less accessories, simple structure, easy assembly, low cost and the like compared with the traditional structure needing the fixed cylinder seat, the knob shaft, a spring, a ball, a bottom cover and a bolt.

Description

A kind of step-by-step movement knob device

Technical field:

The utility model relates to a kind of step-by-step movement knob device.

Background technology:

Step-by-step movement knob device is widely used in electric fan, mechanical type timepiece, on the equipment such as regulator, and the step-by-step movement knob device structure of using on the current market as shown in Figure 1, include stationary cylinder seat 01 and rotation axis 02, stationary cylinder seat 01 inwall forms a plurality of recess 03 along the circumferential direction, the part of rotation axis 02 puts in the stationary cylinder seat 01, place that section rotation axis 02 in the stationary cylinder seat 01 to be processed with cross through hole 04, in this through hole 04, be placed with spring 05 and ball 06, ball 06 cooperates with recess 03, in order to prevent that rotation axis 02 from dropping, bottom at stationary cylinder seat 01 is fixed with bottom 08 by screw 07, the step-by-step movement knob device structure of this traditional structure is comparatively complicated, accessory is many, cause assembling loaded down with trivial details, the cost of manufacture height.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of simple in structure, step-by-step movement knob device that assembling is simple, with low cost is provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of step-by-step movement knob device, include stationary cylinder seat and rotation axis, stationary cylinder seat inwall along the circumferential direction forms multistage recess, the stationary cylinder seat becomes to be clasped with rotation axis, the bottom of rotation axis is extended with the elasticity card arm of one or more, and the card arm puts in the stationary cylinder seat, is provided with the protuberance that cooperates with stationary cylinder seat inwall recess on card arm lateral wall.

Card arm end forms barb, and barb blocks the bottom surface of stationary cylinder seat.

After architecture advances, this step-by-step movement knob device only needs two accessories just passable, and comparing traditional structure needs stationary cylinder seat, rotation axis, spring, ball, bottom and screw, and it is considerably less, simple in structure to have an accessory, assembling easily, low cost and other advantages.

Description of drawings:

Fig. 1 is the structural drawing of this prior art step-by-step movement knob device;

Fig. 2 is the structural drawing of the utility model step-by-step movement knob device;

Fig. 3 is the last TV structure figure of the utility model step-by-step movement knob device;

Fig. 4 is the three-dimensional exploded view of the utility model step-by-step movement knob device.

Embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:

This step-by-step movement knob device includes stationary cylinder seat 1 and rotation axis 2, stationary cylinder seat 1 inwall along the circumferential direction forms multistage recess 3, the bottom of rotation axis 2 is extended with the elasticity card arm 4 of two symmetries, the end of card arm 4 forms barb 5, the bottom outside of barb 5 forms slide guide inclined-plane 6 from bottom to top, card arm 4 puts in the stationary cylinder seat 1, barb 5 stretches out the bottom surface 7 of stationary cylinder seat 1 and blocks, on card arm 4 lateral walls, be provided with the protuberance 8 that cooperates with stationary cylinder seat 1 inwall recess 3, utilize the stepping that recess 3 and cooperating of protuberance 8 realizes rotation axis 2 to rotate.

During assembling, directly inject card arm 4 toward stationary cylinder seat 1, under the effect on slide guide inclined-plane 6, two card arms 4 are subjected to the extruding of stationary cylinder seat wall body and drawdown deformation, continue to inject two card arms 4 this moment, and the barb 5 on card arm 4 passes stationary cylinder seat 1,4 resiliences of two card arms reset, barb 5 blocks the bottom surface of stationary cylinder seat 1, so just finishes and has installed, and operation is very easily simple.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
