The utility model content
The purpose of the utility model is: protective cover can rotate in place when a kind of work will be provided, and can make protective cover get into duty easily or break away from the trailing type safety device in the round metal saw cutting machine of duty.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme.
Trailing type safety device in the described round metal saw cutting machine; Comprise: be hinged on the protective cover on the saw blade safety head through bearing pin; One end of first connecting rod is movably connected on this bearing pin, is characterized in: the other end of first connecting rod is installed with connecting pin, and the upper end of second connecting rod is provided with the lace shape hole; Connecting pin stretches in the lace shape hole; The lower end of second connecting rod is connected with the upper end of spring, and collude on mount pad the lower end of spring, and mount pad is arranged on the support of round metal saw cutting machine; On second connecting rod, also be provided with long slot bore, on mount pad, be fixed with pole, be fixed with alignment pin on the pole, the alignment pin activity is stretched in the long slot bore.
Further; Trailing type safety device in the aforesaid round metal saw cutting machine; Wherein: described lace shape hole is a lace shape hole that has the strip through hole; Described connecting pin is the connecting pin that the end has the strip end block, and the strip end block of connecting pin end can extend in the strip through hole in lace shape hole.
The beneficial effect of the utility model is: during work, described protective cover can rotate in place, and can protect operator and related personnel well.In the time need not using protective cover; As long as connecting pin is deviate from from the lace shape hole; Otherwise just can use protective cover as long as connecting pin inserted in the lace shape hole, so just can make protective cover entering duty or disengaging duty very easily, improve operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the trailing type safety device in the described round metal saw cutting machine of the utility model.
Fig. 2 is the structure for amplifying sketch map of first connecting rod among Fig. 1, second connecting rod part.
Fig. 3 is the structural representation when protective cover broke away from duty after connecting pin and lace shape hole broke away from.
The specific embodiment
Below in conjunction with accompanying drawing the trailing type safety device in the described round metal saw cutting machine of the utility model is further described.
Like Fig. 1, Fig. 2, shown in Figure 3; Trailing type safety device in the described round metal saw cutting machine; Comprise: be hinged on the protective cover 2 on the saw blade safety head 3 through bearing pin 7, an end of first connecting rod 26 is movably connected on this bearing pin 7, and the other end of first connecting rod 26 is installed with connecting pin 8; The upper end of second connecting rod 10 is provided with lace shape hole 25; Described lace shape hole 25 is a lace shape hole that has the strip through hole, and described connecting pin 8 has the connecting pin of strip end block for the end, and the strip end block of connecting pin 8 ends can extend in the strip through hole in lace shape hole 25.The lower end of second connecting rod 10 is connected with the upper end of spring 11, and collude on mount pad 12 lower end of spring 11, and mount pad 12 is arranged on the support 17 of round metal saw cutting machine; On second connecting rod 10, also be provided with long slot bore 28, on mount pad 12, be fixed with pole 18, be fixed with alignment pin 19 on the pole 18, alignment pin 19 activities are stretched in the long slot bore 28.
The operation principle of the trailing type safety device in the described round metal saw cutting machine of the utility model is: the same with normally used round metal saw cutting machine; In the round metal saw cutting machine; Saw blade 4 is installed on the head 9, and cutter lid 5 covers in saw blade 4 outsides, and the top of saw blade 4 is equipped with safety head 3; Head 9 is hinged on the mount pad 12 through jointed shaft 13, and operating handle 1 also is installed on the head 9.When needs cut work, squeeze grip 1 referring to shown in Figure 1, made head 9 be with saw blade 4 to move downward around jointed shaft 13 downwards, till the material with required cutting cuts off.In this process; Protective cover 2 can be along with safety head 3 down motion together, because the upper end of first connecting rod 26 is movably connected on the bearing pin 7, first connecting rod 26 flexibly connects through lace shape hole 25 and connecting pin 8 with second connecting rod 10 each other; Collude on mount pad 12 through spring 11 again the lower end of second connecting rod 10; And be movably set with the alignment pin 19 that is bearing on the mount pad 12 in the long slot bore on the second connecting rod 10 28, therefore, first connecting rod 26 and the continuous translation-angle of second connecting rod 10 meetings are to adapt to the change in location of protective cover 2 in this process; Guarantee that protective cover 2 can rotate in place in time, thereby protected operator and related personnel well.After cutting work is accomplished, upwards lift handle 1, make head 9 be with saw blade 4 to move upward around jointed shaft 13, in this process, under the effect of spring 11, protective cover 2 can reset rapidly.
When a certain cutting task is accomplished, in the time of need not using protective cover 2, as long as connecting pin 8 is deviate from from lace shape hole 25, so just can be made protective cover 2 break away from duty very easily, easy to operate referring to shown in Figure 3, improved operating efficiency.The strip through hole is set in lace shape hole 25 and in the effect that connecting pin 8 ends are provided with the strip end block is: must the strip end block be aimed at the strip through hole during installation could insert connecting pin 8 in the lace shape holes 25; Also must the strip end block be aimed at the strip through hole when taking apart could throw off connecting pin 8 from lace shape hole 25, connecting pin 8 just can not deviate from from lace shape hole 25 easily when work like this.
