Abstract
The utility model relates to an improved universal wheel device for a safety door of a knitting machine. The utility model comprises a universal wheel which can be arranged in a universal wheel seat in a rolling method, and a fixing seat which is connected with a safe door frame. The utility model is characterized in that the utility model also comprises a slide rod seat, a slide rod and a spring, wherein the slide rod seat is fixedly arranged on the fixing seat, and the slide rod which is movably arranged in the slide rod seat can slide up and down; the spring is butted between the slide rod seat and the slide rod, and the universal wheel seat is connected with the lower end of the slide rod; the upper end of the slide rod penetrates through the slide rod seat, and a screw is arranged on the upper end of the slide rod and is matched with a screw nut; the slide rod is supported on the slide rod seat through the screw nut. Through the adjustment of the screw nut, the slide rod can be conveniently lifted up and down. With the structure, when a safety door is opened and closed, because of the action of the spring and the movable slide rod, the universal wheel can fluctuate with the ground to be automatically adjusted up and down for guaranteeing that the universal wheel is always pressed on the ground, therefore the safety door has the advantages of stable opening and closing, flexible and free operation, difficult deformation and damage for a doorframe, and extended service life.
Description
Technical field
The utility model relates to the knitting machine safety door universal wheel unit of architecture advances.
Background technology
For the ease of taking out braided fabric, be provided with peristome in the bottom of knitting machine, and, damage for fear of the machine that operator's false touch runs up, but at the safety door 11 of this peristome setting switch.As shown in Figure 1, safety door generally is to be movably articulated on the knitting frame by rotating shaft, also is equiped with universal wheel unit on safety door, supports and guide effect to play.Existing knitting machine safety door universal wheel unit, its structure comprises universal wheel 12 as shown in Figure 2, and universal wheel 12 rollably is arranged in the universal wheel seat 13, this universal wheel seat 13 is connected holder 14 by securing member, and holder 14 is connected on the safe doorframe edge.This roller devices has characteristic of simple structure.But said structure mainly has the following disadvantages: adjustment amount is limited up and down for (1) universal wheel mechanism, and needs manually to adjust, and is cumbersome.(2) if ground has injustice slightly, universal wheel mechanism will built on stilts, makes safety door unsettled, will make the safety door easy deformation like this, and instability during switch.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of switch to stablize, adjust improved easily knitting machine safety door universal wheel unit.
For achieving the above object, the utility model adopts following technical scheme: improved knitting machine safety door universal wheel unit, comprise the universal wheel that rollably is arranged in the universal wheel seat, and be connected holder on the safe doorframe, it is characterized in that: also comprise slider block, slide bar, spring, slider block is installed in holder, and the slide bar active configuration is in slider block and can slide up and down, spring holds between slider block and slide bar, and universal wheel seat is connected the lower end of slide bar.
Adopt this structure, during the safety door switch, because the effect of spring and movable slide bar, universal wheel is risen and fallen and up-down adjustment automatically with ground, guarantees that universal wheel compresses ground all the time, thus make the safety door switch steadily, go slick freely, and doorframe is not yielding, damage, has improved service life.
As further improvement, the upper end of slide bar is arranged in outside the slider block, has spiral on this end and is equipped with nut, and slide bar passes through this nut support on slider block.By adjusting this nut, can make the upper and lower lifting of slide bar easily.
Description of drawings
Fig. 1 is the schematic diagram with knitting machine of safety door.
Fig. 2 is the schematic diagram of existing knitting machine safety door roller devices.
Fig. 3 is the schematic diagram of improved knitting machine safety door universal wheel unit.
The specific embodiment
With reference to Fig. 3, improved knitting machine safety door universal wheel unit comprises:
Slider block is made up of hollow base frame 151 and the gland 152 that is connected hollow base frame 151 upper ends.The lower end of hollow base frame 151 has helical structure, and this end places the installing hole of holder 14, and is fastening by nut 153, pad 154, thereby slider block is fixed on the holder 14.The endoporus of hollow base frame 151 play the guiding role to sliding up and down of slide bar 16.
Slide bar 16 can slide up and down to place hollow base frame 151.Its lower end cooperates with the endoporus of hollow base frame 151 just, in case on-slip bar 16 produces swing when sliding, avoids influencing the flexibility of safety door running.Slide bar 16 upper ends are passed gland 152 and are positioned at outside the slider block, and this end has helical structure and is equipped with nut 161, and slide bar 16 is 161 spacing by this nut, be supported on the gland 152, by adjusting this nut, can make slide bar 16 upper and lower liftings easily.Slide bar 16 lower ends also have axially extended screw, are used to connect universal wheel seat 13.
Spring 17 holds between gland 152 and slide bar 16 lower ends.
The operation principle of knitting machine safety door universal wheel unit is as follows: universal wheel 12 is connected slide bar 16 lower ends by universal wheel seat 13, slide bar 16 can slide up and down to place slider block and be subjected to spring 17 effects, when the safety door switch, universal wheel 12 rises and falls with ground and up-down adjustment and compress ground all the time automatically, guarantee the safety door switch steadily, go slick freely.Because universal wheel 12 is supported on ground all the time, and doorframe can be not unsettled, not yielding, damage has improved service life simultaneously.
