Abstract

The utility model discloses an elastic ring guide and limit device, which is characterized by comprising a shaft and a plurality of limit wheels, the center of the limit wheel is provided with a central hole and an inner ring groove, an elastic ring is embedded in the inner ring groove, the shaft passes through the inner hole of the elastic ring, the outer diameter of the shaft is larger than the inner diameter of the elastic ring, and is smaller than the diameter of the central hole of the limit wheel. With the technical scheme, the inner ring groove of the limit wheel is provided with the elastic ring, the shaft passes through the inner hole of the elastic ring, the diameter of the elastic ring is smaller than the outer diameter of the shaft, and the elastic ring is clamped on the shaft, so the limit wheel is fixed on the shaft, the position of the limit wheel on the shaft can be changed through being pushed by force larger than the clamp force, thereby achieving the effect of flexible adjustment.

Description

A kind of elastic ring guide position limiter

Technical field

The utility model relates to the limit stoper technical field, particularly relates to a kind of elastic ring guide position limiter of movable adjusting.

Background technique

Guide position limiter generally has three kinds of modes on the market at present, and a kind of is mode with the fastening piece stator wheel; Second kind is to adopt outer folder elastic force to make the upper saw pulley clamp shaft, and the third is that upper saw pulley and axle are made of one structure.Above-mentioned three kinds all exist: cost is high, can't guide and limit on the foreign steamer and regulate deficiency such as inconvenience.

Summary of the invention

The utility model provides an Artenkreis guide position limiter to the problems referred to above, reaches guiding that material is provided quickly and easily and spacing purpose.

For achieving the above object; The technological scheme that the utility model proposed is: a kind of elastic ring guide position limiter is characterized in that: comprise axle, a plurality of limited wheel, there are center hole and inner groove in described limited wheel center; Embedded elastic ring on the described inner groove; Described axle passes the elastic ring endoporus, and the axle external diameter is bigger than elastic ring internal diameter, and is littler than limited wheel center-hole diameter.

Further, described elastic ring is the rubber ring of remaining silent, the steel ring of opening or the plastic tube of opening.

Further, the cross section of inner groove in the described limited wheel center hole and outer groove can be circular, square a, triangle, trapezoidal etc.

Further, described axle is a hollow or solid, and axle is a smooth bar, is mainly used in support limit and takes turns and be installed on other parts, and the material of axle can be plastics, metal, timber etc.

Further, also have outer groove on the described limited wheel, directly be used for sliver shape object such as belt, line etc.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

As shown in Figure 2, a kind of elastic ring guide position limiter comprises axle 3, a plurality of limited wheel 1; There are center hole and inner groove 11 in limited wheel 1 center, embedded elastic ring 2 on the inner groove 11, and axle 3 passes elastic ring 2 endoporus; Axle 3 external diameters are bigger than elastic ring 2 internal diameters, and are littler than limited wheel 1 center-hole diameter.Elastic ring 2 can be the rubber ring of remaining silent, the steel ring of opening or the plastic tube of opening in addition.Axle 3 is smooth hollow or solid bar.

As shown in Figure 1, compare with Fig. 2, also have outer groove 12, outer groove 12 directly to be used for sliver shape object such as belt, line etc. on the limited wheel 1; Big and wide object then leads with the distance of axle 3 between two limited wheels 1.

Like Fig. 3, shown in Figure 4; Earlier limited wheel 1 inner groove 11 is loaded onto elastic ring 2; Axle 3 passes elastic ring 2 endoporus, and elastic ring 2 bandings are on axle 3, and limited wheel is fixed on the axle like this; Use force urges limited wheel can change its position on axle greater than clamping force, reach can free adjusting effect.

In sum, adopt technique scheme, the limited wheel inner groove is loaded onto elastic ring; Axle passes the elastic ring endoporus; The elastic ring inner ring diameter is less than the external diameter of axle, and the elastic ring banding is on axle, and limited wheel is fixed on the axle like this; Use force urges limited wheel can change its position on axle greater than clamping force, reach can free adjusting effect.The size of elastic force is by the internal diameter of elastic ring, the external diameter of axle and the material decision of elastic ring in addition; Provide one to supply bar, ribbon or the guiding of shaft conveying and spacing space between any two adjacent limited wheels, the groove on the limited wheel also provides a guiding and spacing space; The coupling of many these devices of group can better limit guiding and the position-limiting action that is sent material.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.

Claims
