Abstract

The utility model discloses a pulling and pushing type device for electric arc welder moving, which is composed of a slide bar which can be in or be pullout from the body case and a handle which is movably connected with the electric arc welder. When the welder stops, the device doesn't take up space and doesn't influence beauty; when the welder moves, different heights people use force with labor saving at natural pose; the utility model can also avoid toppling and is favorable for the electric arc welder in upright or horizontal type structure.

Description

Shifter for electric arc welder

The utility model relates to the novel mobile device that a kind of arc welder is used, and can be suitable for the arc welder of various profile styles.

Used arc welder profile is divided two classes.Oriental countries is used vertical structure more, and feature is that machine height ratio lengthwise is big.This structure is compact, and floor space is little in the use, but higher because of center of gravity, and the visual field is little in moving, and moves difficulty, and is especially obvious when the road conditions difference.Western countries use horizontal type structure more, it is characterized in that lengthwise is taller and bigger than machine.Bear the sunlight area when this structure is used out of doors and the ground level heat swept area is big, be difficult to directly move because of the machine height again with hand push.Therefore the drawing handle of horizontal type structure has two classes.The oblique fixedly pushing-type of first kind Jiong type handle have packing measurement(s) big, use floor space big; Bend wiring and stir operating knob after easily run into the back skull when lifting body; Downward additional component is arranged in promotion; During pulling, problem such as could exert all one's effort only falls back.But the handle of separation and retraction fuselage formula is low because of distance ground about second class, must mention handle earlier before the pulling, makes welding machine break away from the left alone without help configuration state that is supported by fore-stock, only moves with pair of rear wheels.Center of gravity should be between wheel shaft and handle in moving, and considers that the human body height differs and overcomes concrete service condition such as roadblock, and design gravity must be partial to handle side, the load during this causes increasing the weight of to move.

The purpose of this utility model not only can be drawn but also can push away in order to provide a kind of, and can adapt to the arc welder mobile device of people's needs of different heights exactly, and this device is specially adapted to the arc welder of vertical structure.

Fig. 1 is when to be that welding machine is left alone without help put, the state of this mobile device.

Fig. 2 be welding machine when pulled, the state of this mobile device.

Fig. 3 is a welding machine when being pushed, the state of this mobile device.

Any cover about mobile device among these three figure is only represented in two covers, about two covers identical, place left and right sides in the cabinet of arc welder respectively.

Structure of the present utility model is shown in Fig. 1, mainly is made up of two slide bars 1, two handles 3, two collars 6.The inner of bar is with the location and cover 8, and the outer end is removed two sides and stayed horizontal porose middle bossy body, with the recess-mounted of handle 3 ends.Transverse holes is used to be bumped into cotter axle 2.One end of handle 3 is cuted out mid portion, to include the bossy body of bar in.This end of handle 3 is laterally porose, is equipped with to penetrate cotter axle 2.Handle 3 can be made 180 degree around cotter axle 2 and rotate.Handle 3 is consistent with the diameter of slide bar 1.The other end of handle is a sheath 4.Embed outstanding bayonet lock 5 on the handle body at sheath rear.Have n-type groove on the collar 6, groove width is slightly larger than bayonet lock 5 diameters.

Welding machine is left alone without help when putting, and slide bar all pushes in the box outer cover of welding machine except that the termination, and handle overhangs under the bar head, and the collar is stuck in the bayonet lock, and bar cover groove because of the location to be wedged and can not skid off by elasticity top 9.

When drawing welding machine, the extended part of slide bar is all pulled out casing, and handle freely goes to the high angle that adapts to the people around cotter axle.This angle open the step, to change leg etc. constantly different, can transfer to the most suitable application of force state naturally.When machine drawing turns to, allow slide bar rotate, to adapt to the needs of the oblique application of force around the axis of self.

During the padding machine, slide bar all pushes except that the termination in the box outer cover of welding machine, and the collar is taken off to the attachment of handle and slide bar from bayonet lock, makes handle can not become the prolongation of slide bar around the cotter axle rotation, is convenient to the application of force.

Handle has increased the live part of slide bar, and makes it to adapt to the people of different heights.

The welding machine of vertical structure adds this device, and the people's heel that draws can not run into casing, and variable pushing away to drawing is more laborsaving when mobile on way far away, and road conditions are walked around or removing obstacles owing to can see clearly when drawing, and are safe and reliable, and original advantage of vertical structure still keeps.

After the welding machine of horizontal type structure is used this device instead, can use four roller structures instead, adopt pulling to reduce labor intensity.

Vertical or horizontal type structure no matter, this device all can stretch out from the welding machine back, does not affect the appearance.

Sheath 4 is made by soft material, not only makes handgrip but also can avoid wiping the casing finish paint.

Chute 7 can be fixed on about branch on the proper site such as frame, panel, top cover at the inner suitable height of the box outer cover of welding machine.

Claims

1, by slide bar 1, handle 3, the collar 6, the arc welder mobile device that chute 7 is formed is characterized in that handle 3 one ends can make 180 degree around lateral pin and rotate, the sheath 4 that the other end has flexible material to make has the collar 6 on the handle body.

2, by the described arc welder mobile device of claim 1, an end that it is characterized in that handle 3 partly becomes groove in the middle of cutting out, and the bayonet lock 5 that protrudes the surface is arranged on the handle body.

3, by the described arc welder mobile device of claim 1, it is characterized in that the collar 6 has n-type groove, can take off to the attachment of handle and slide bar from bayonet lock 5.

4, by the described arc welder mobile device of claim 1, an end that it is characterized in that slide bar 1 is removed two sides becomes convex body, and the other end has the location to cover 8.
