Abstract

The utility model provides a wheel axle with a line-pressing device, which comprises a substrate and a main wheel axle, and is characterized in that the substrate is provided with a plurality of driven wheel axles which are paralleled to the axial direction of the main wheel axle, and the driven wheel axles are closely contacted with the main wheel axle and are driven by the main wheel axle to rotate so as to prevent the cable against loosening, groove jumping and eccentric wear. The wheel axle with the line-pressing device is applicable to all wheel axle devices utilizing a pulley or a reel, such as an elevation clothes rack and a car glass-frame riser.

Description

A kind of wheel shaft with cord grip

One, technical field:

The utility model relates to a kind of wheel shaft of rope drive

Two, background technique:

Drying rack in the background technique is used for the wheel shaft of rope drive, rope is job-hopping easily in the wire casing of wheel shaft, edge also easy and wire casing weares and teares mutually, though protective housing is arranged, protective housing is static, can not closely contact with the wheel shaft outer rim of rotating, also leave certain clearance, so anti-hopping and anti-eccentric wear effect also are not very perfect, in electric clothes hanger, be used to twine the wheel shaft of rope in addition, also be to cause damage because protective housing can not press wheel shaft and rope.

Three, summary of the invention:

At existing problem in the background technique, the purpose of this utility model provides a kind of wheel shaft with cord grip, it can be under any circumstance all tightly push down main axle and rope does not make it get loose and eccentric wear.

The technological scheme that the utility model adopted is: comprise pedestal, wheel shaft, on described pedestal, also be provided with a plurality of and main axle parallel to an axis passive wheel shaft arranged side by side, outer garden week along main axle 2 evenly gathers, the outer garden week of passive wheel shaft 4 contacts with tight rolling of outer garden week of main axle 2, driven by main axle and along with rotation, thereby can tightly suppress main axle and rope, both not have resistance, can prevent again rope get loose the job-hopping and eccentric wear.

Four, description of drawings:

Fig. 1 is that the utility model is used for the wheel shaft schematic representation that the multi-turn rope twines.

Fig. 2 is the right pseudosection of Fig. 1.

Fig. 3 is the wheel shaft schematic representation that the utility model is used for the individual pen rope slip.

Fig. 4 is the partial sectional view of Fig. 3.

Fig. 5 is the right elevation of Fig. 3.

Fig. 6 is the elastic element wire spring 5 among Fig. 3, Fig. 4, Fig. 5.

Five, embodiment:

Below in conjunction with accompanying drawing the utility model is done description:

Embodiment 1 is as Fig. 1, shown in Figure 2,1 is the pedestal that supports main axle 2 among the figure, the 3rd, be around in the rope on the wheel shaft 2, can be wire rope or other material, the 4th, be loaded on the additional passive wheel shaft on the pedestal 1, the outer garden week of passive wheel shaft 4 contacts with tight rolling of outer garden week of main axle 2, certainly can also be along a plurality of passive wheel shafts 4 that evenly gather in the outer garden week of main axle 2, main axle 2 drives passive wheel shaft 4 and rotates when rotating, thus tightly push down main axle 2 and rope 3, prevent loosening and job-hopping, the multi-circle spiral flow groove is arranged on the main axle 2, be used to twine rope, present embodiment is applicable to the Take up unit of electric clothes hanger, also goes for automobile glass lifter.

Embodiment 2 is as Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, main axle 2 is installed in the pedestal 1, also be arranged with two passive wheel shafts 4 arranged side by side with the main axle parallel to an axis on the both sides of main axle, the outer garden week of passive wheel shaft 4 contacts with tight rolling of outer garden week of main axle 2, passive wheel shaft 4 is not limited to 2 in the practical application, passive wheel shaft 4 holds hole 6 and can radially extend to the main axle axis direction on the pedestal 1, on the spindle nose of the two ends of passive wheel shaft, respectively have an elastic element 5 with the driven wheel axial compression to main axle, elastic element 5 in the present embodiment adopts wire spring, as shown in Figure 6, the two ends of spring 5 can embowment, blocks spindle nose and is difficult for slippage.The effect that passive wheel shaft 4 is subjected to spring 5 tightly push down main axle 2 and rope 3 is all the time followed main axle 2 and is rotated, and prevents rope 3 loosening and job-hoppings, and can prevent eccentric wear to have useful effect.

Claims

1, a kind of wheel shaft with cord grip comprises pedestal, main axle, it is characterized in that: also be provided with a plurality of on described pedestal and main axle parallel to an axis passive wheel shaft arranged side by side, the outer garden week of passive wheel shaft contacts with the outer garden week rolling of main axle.

2, the wheel shaft of band cord grip according to claim 1 is characterized in that: described passive wheel shaft is fixedlyed connected with pedestal.

3, the wheel shaft of band cord grip according to claim 1 is characterized in that: passive wheel shaft and pedestal flexibly connect, and have the hole of holding that passive wheel shaft is installed on pedestal.

4, the wheel shaft of band cord grip according to claim 3 is characterized in that: described hold the hole can be radially to main axle axis direction lengthening, on the spindle nose of the two ends of passive wheel shaft, respectively have an elastic element with the driven wheel axial compression to main axle.
