Abstract
The utility model relates to a damping adjusting screw, which mainly comprises a screw, and is characterized in that the front end of the screw is manufactured into a stair landing shape; a disc spring is arranged on a lower step of the stair landing; the front end of the disc spring is provided with a damping head; and the damping head is limited inside by a boss at the front end of the lower step. The damping adjusting screw has the advantages of simple structure, realization of adjusting damping force by adjusting tightness of the screw, and convenience in use.
Description
Technical field
The utility model relates to a kind of adjusting screw, is specifically related to a kind of damping adjusting screw.
Background technique
Owing to make and installation errors, there are drift in the lamp holder of operation shadowless lamp and connecting part branch thereof, can't be implemented in the location of arbitrary position.Therefore, in operation shadowless lamp, provide damping force to realize the location of lamp holder and its joining part by the damping screw usually.
The damping screw requires suitable damping force can be provided, and this damping force can not be too little, to guarantee positioning requirements; Simultaneously, damping force again can not be too big, make user's comfortable feel when mobile lamp holder and joining part thereof.In addition, in the ordinary life scope, after the damping screw wearing and tearing, the location that the damping force of also wanting to provide sufficient satisfies lamp holder and joining part thereof.
The damping screw is to screw by screw thread, the distortion of roof pressure dish spring, thus dish spring roof pressure damping head produces frictional force, and then effectively lasting damping force is provided, the big I of damping force realizes by the adjusting screw degree of tightness.
The model utility content
Technical problem to be solved in the utility model is to provide damping adjusting screw a kind of simple in structure, easy to operate.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of damping adjusting screw, its main body is a screw, it is characterized in that: described screw front end is made the halfpace shape, and the low platform of halfpace is provided with the dish spring, and dish spring front end is provided with the damping head, and the damping head is limited in the inboard by the boss of described low platform front end.
The beneficial effects of the utility model are: simple in structure, realize the damping force size by the adjusting screw degree of tightness, and easy to use.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of damping adjusting screw, its main body are screws 1, and screw 1 front end is made the halfpace shape, and the low platform of halfpace is provided with dish spring 2, and dish spring 2 front ends are provided with damping 3, and damping 3 is limited in the inboard by the boss of low platform front end.
The damping screw is to screw by screw thread, damping 3 roof pressure dish springs, 2 distortion, thus dish spring 2 elastic force act on damping 3 a generation frictional force, and then effectively lasting damping force is provided, the big I of damping force realizes by adjusting screw 1 degree of tightness.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
