Description
Technical field:
The utility model relates to the technical field of drawing yard instrument, small-sized adjustablely draws a yard device more specifically to a kind of.
Background technology:
Code is drawn to be instrument common in machinery maintenance, and the current code that draws varies, what some were small-sized draws code to carry for convenience, that is generally drawn the pulling claw bar of code to do is shorter, thus can save the space of carrying, but under certain situation, the thickness of workpiece of some codes to be drawn is thicker, shorter pulling claw bar cannot meet it and draw a yard requirement, thus can only carry and larger draw code.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of small-sized adjustable yard device that draws, and it can regulate the pulling claw bar drawing code, thus make little draw code to meet thicker workpiece draw code work.
Technology solution of the present utility model is as follows:
One is adjustable draws a yard device, comprise supporting traverse and push rod, the middle part of supporting traverse forms screwed hole, push rod is bolted with in the screwed hole of supporting traverse, the upper end of push rod forms projection, projection is plugged with round bar, the two ends of supporting traverse are plugged with montant, montant forms vertical dovetail groove, be plugged with expansion link in montant dovetail groove, the lower end of expansion link is fixedly connected with pulling claw, and the bottom surface of described montant dovetail groove forms several jacks, be plugged with adjusting bolt in jack, adjusting bolt is screwed onto on expansion link.
Two side in the middle part of described supporting traverse forms flank, and the screwed hole on supporting traverse is molded on flank and supporting traverse, and described flank is welded with reinforcing sleeve, and reinforcing sleeve is screwed onto on push rod.
Described jack is vertically evenly distributed on montant, and the adjusting bolt be screwed onto on expansion link is provided with two.
The two ends of described supporting traverse are provided with limited block, and limited block is bolted on supporting traverse.
The two ends of described round bar are plugged with rubber handle cover.
The beneficial effects of the utility model are:
Which propose and a kind ofly small-sized adjustablely draw a yard device, it can draw the pulling claw bar of code to carry out telescopic adjustment, from the length that can increase pulling claw bar, thus meet be convenient for carrying while can meet again thicker workpiece draw code work.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 of the present utility modelly changes angled arrangement schematic diagram;
Fig. 3 of the present utility modelly changes angled arrangement schematic diagram.
In figure: 1, supporting traverse; 2, push rod; 3, round bar; 4, montant; 5, expansion link; 6, adjusting bolt; 7, pulling claw; 8, reinforcing sleeve; 9, limited block; 11, flank; 21, projection; 31, rubber handle cover; 41, dovetail groove; 42, jack.
Detailed description of the invention:
Embodiment: see Fig. 1, 2, shown in 3, one is adjustable draws a yard device, comprise supporting traverse 1 and push rod 2, the middle part of supporting traverse 1 forms screwed hole, push rod 2 is bolted with in the screwed hole of supporting traverse 1, the upper end of push rod 2 forms projection 21, projection 21 is plugged with round bar 3, the two ends of supporting traverse 1 are plugged with montant 4, montant 4 forms vertical dovetail groove 41, expansion link 5 is plugged with in montant 4 dovetail groove 41, the lower end of expansion link 5 is fixedly connected with pulling claw 7, the bottom surface of described montant 4 dovetail groove 41 forms several jacks 42, adjusting bolt 6 is plugged with in jack 42, adjusting bolt 6 is screwed onto on expansion link 5.
Two side in the middle part of described supporting traverse 1 forms flank 11, and the screwed hole on supporting traverse 1 is molded on flank 11 and supporting traverse 1, and described flank 11 is welded with reinforcing sleeve 8, and reinforcing sleeve 8 is screwed onto on push rod 2.
Described jack 42 is vertically evenly distributed on montant 4, and the adjusting bolt 6 be screwed onto on expansion link 5 is provided with two.
The two ends of described supporting traverse 1 are provided with limited block 9, and limited block 9 is bolted on supporting traverse 1.
The two ends of described round bar 3 are plugged with rubber handle cover 31.
Operation principle: originally draw yard device to adopt pulling claw bar during combination to replace the fixing all-in-one-piece pulling claw bar of tradition, this pulling claw bar is by expansion link 5 and montant 4, expansion link 5 can carry out telescopic adjustment in montant 4, and the relative position of expansion link 5 and montant 4 can be limited by adjustment in use bolt 6, thus change the length of pulling claw bar, thus can meet foot thicker workpiece draw code work, simultaneously shrink time save space, be convenient for carrying.
