Abstract

The utility model relates to an improved foot rest for knitting machines, which is characterized in that the bottom of a supporting board on both sides of a foot rest is provided with a roller groove; the roller groove can be assembled with rollers; the side of the roller groove on the bottom of the supporting board is provided with a foot rest hole; the foot rest hole can be assembled with a foot rest for adjusting height. When the position of a knitting machine need moving, the foot rest is retracted into the foot rest hole and the four rollers are kept close to the ground to move the knitting machine conveniently; when the knitting machine is moved to a fixing position, the foot rest is extended out the foot rest hole and one side of the rollers props off the ground to provide an excellent positioning function and make use more convenient.

Description

Improved wheeled frame for needle vehicle

The utility model relates to a kind of improved sewing machine foot rest, and it mainly is with appropriate structural arrangements, can allow the user can be lighter and laborsaving when the shift position, when desire is used, can adjust the locating effect that obtains a kind of excellence easily again.

Sewing machine is in relevant industries, suitable wide of the scope of its use, all can see its trace in the leather processing industries even in textile industry, decoration industry, only on existing this type of sewing machine foot rest structure, all are integral structures of taking the iron casting moulding, though it can have splendid structural strength and stability, when desire moves the sewing machine position, a quite heavy burden, can profoundly understand its structural disadvantages place as long as this type of existing sewing machine structure is illustrated:

The weight of sewing machine itself is not light, if it is set up on the sewing machine foot rest, will make its overall weight reach 100 kilograms nearly again, and this kind weight is for two adults, and real unbearably load is so it all can cause considerable puzzlement when selling carrying and storage.

In order to solve this problem, there is relevant manufacturer to adopt progressive design again, four groups of rollers are assembled in its support plate bottom surface, both sides at conventional fixed formula sewing machine foot rest, so can be when desire moves the sewing machine position, passed easily, need not again it have been removed displacement, so when releasing, extensively be subjected to user's hobby, only this structure is but found when the user uses, its fixed effect is not good enough, because the roller that it adopted is to make the movable roller that 360 deg rotates, so in use, as long as the user relies on its side a little or adds man-hour slightly to its application of force, can make that promptly sewing machine is shifted, even because the ground injustice, and in use also can form displacement, cause the puzzlement in the processing because of the vibrations of sewing machine.

Main purpose of the present utility model is: a kind of improved sewing machine foot rest is provided, it mainly is to be provided with roller groove in support plate bottom surface, foot rest both sides, and can assemble roller therein, be provided with leg holes in support plate bottom surface roller groove side again, and can assemble a height adjustable leg therein, when desire moves the sewing machine position, can be with in the leg retraction leg holes, and allow four rolling be attached on the ground, and can be passed easily, again when passing to the location, can be with leg by stretching out in the leg holes, and the roller of a side is pushed up overhead, and excellent positioning action can be provided, it is more convenient to allow use go up.

A purpose more of the present utility model is: a kind of improved sewing machine foot rest is provided, and its edge, support plate stage casing is provided with the bulge loop of one, and can set up hand tools in this bulge loop.

Another purpose of the present utility model is: provide a kind of sewing machine foot rest to improve structure, its support plate is to make with plastic material, and can make the weight of its whole sewing machine foot rest lighter, and is all more light and make things convenient for when carrying and storage.

The utility model provides a kind of improved sewing machine foot rest, comprise foot rest, panel, support plate, it mainly is to be provided with roller groove in support plate bottom surface, foot rest both sides, and can assemble roller therein, be provided with leg holes in support plate bottom surface roller groove side again, and can assemble a height adjustable leg therein, this leg can fix its extension position in leg holes by adjusting nut.

Aforesaid structure improved sewing machine foot rest is characterized in that: the edge, stage casing at support plate is provided with the bulge loop that can settle hand tools.

Aforesaid sewing machine foot rest structure-improved, it is characterized in that: the support plate of foot rest both sides is made by injection-moulding plastic.

Design of the present utility model is at the bad improvement of doing of existing sewing machine foot rest structure design, it is cooperated with the appropriate of leg 40 by roller 30, can allow the user when desiring to move sewing machine, can be passed easily, again when the fixing use of desire, can cooperate leg 40 that positioning action is provided again, its unlikely generation easily is shifted, its true tool progressive and practicality, certainly the utility model is made the support plate 20 of foot rest 10 with injection-moulding plastic, the panel 11 that also can cooperate injection-moulding plastic to make simultaneously, and whole weight is significantly alleviated, favourable transportation and sales and storage, the design of other its bulge loop 25 also can allow the user will adjust the spanner of nut 41 usefulness or the instrument of other sewing machines utilization is settled wherein, and a convenience and practicality are provided really.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.

Fig. 1 is a schematic appearance of the present utility model.

Fig. 2 is a support plate cross-sectional view of the present utility model.

Fig. 3 is the partial structure schematic diagram of support plate assembling roller of the present utility model and location footprint.

See also shown in Figure 1, it is a schematic appearance of the present utility model, can see foot rest 10 of the present utility model thus among the figure is made of the support plate 20 of panel 11 with the both sides, below, on this panel 11, be provided with the assembly hole 12 that the assembling sewing machine is used, be connected with connecting rod 27 and cross bar 28 20 of both sides support plates again, to promote the steadiness of whole foot rest 10, one control pedal 29 is installed on this cross bar 28 simultaneously, use when operating sewing machine (these structures are all identical with existing structure, do not give unnecessary details so do not add in addition) for the user.

Cooperate the utility model support plate 20 cross-sectional view of Fig. 2 to see it, when finding out structure feature of the present utility model place clearly, support plate 20 wherein of the present utility model is to make with injection-moulding plastic, wherein be provided with the crisscross ribs of multiple tracks, be provided with slightly recessed engagement groove 21 in the one side, it can be for the usefulness that is assembled bar 27, be provided with cross bar groove 22 in the bottom surface of this support plate 20 again, it can be in order to assembling cross bar 28, place, nearly two ends is provided with a roller groove 23 respectively in these support plate 20 bottom surfaces again, and can in this roller groove 23, assemble the roller 30 of vertical support plate 20 directions, be provided with a leg holes 24 in these support plate 20 bottom surfaces one roller groove, 23 sides again, wherein can cooperate assembling one leg 40, be provided with the bulge loop 25 of one in addition at edge, support plate 20 stage casing, it is available for users to settle the spanner or the relevant hand tools of various adjustment usefulness.
