Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further details below by concrete mode of execution.
As shown in Figure 4, a kind of lasing safety door assembly, be used to the harm of protecting laser emission that people and environment etc. is caused, it comprises: fixing bottom-plate 6, the supporting element 7 that is fixed on these base plate 6 both sides and beam 4, protective door 5, balancing weight 2 and lever 3, wherein, described lever 3 be provided with first end 32 that is connected with protective door 5, and and first end, 31 second opposed end 33, wherein, be provided with the fulcrum 31 that is fixed on the supporting element 7 between first end 32 and second end 33, described balancing weight 2 is between described second end 32 and fulcrum 31; Beam 4 is positioned at described balancing weight 2 belows, and protective door 5 is that rotating center is done the several angle rotation with fulcrum 31, to reach the harm that prevents that laser emission from causing people and environment etc.
As shown in Figure 4, described balancing weight 2 variable positions is placed between described lever 3 second ends and lever 3 fulcrums 31.For Different Weight, difform protective door, only need to regulate the front and back position of balancing weight, just can make the lasing safety door assembly when arm of force level, keep static balance.
As Fig. 5, Fig. 6, shown in Figure 8, described lasing safety door assembly has following design parameter: 0 °＜A≤45 °, and 0 °≤B＜45 ° and B＜A, wherein B is the angle of lever 3 and horizontal plane, A is the line of protective door center of gravity and fulcrum 31 and the angle of lever 3.
The working principle of brief description the foregoing description:
As shown in Figure 5, when the protective door 5 of lasing safety door assembly was in equilibrium process, protective door moment was: T1=G1*R*cos (A+B).Wherein T1 is a protective door moment, and G1 is a protective door weight, and R is the distance of protective door distance of centre of gravity balance pivot 31, and A is the line of protective door center of gravity and lever 3 fulcrums 31 and the angle of lever 3, and * represents multiplication.Balancing weight moment is T2=G2*r*cosB.Wherein T2 is a balancing weight moment, and G2 is a balancing weight weight, and r is the distance of balancing weight distance of centre of gravity balance pivot 31, and B is the angle of lever 3 and horizontal plane, and B is 0 ° in Fig. 5.When the lasing safety door assembly is in state of equilibrium, T1=T2.So G1*R*cosA=G2*r.We will adjust the front and back position of regulating balancing weight, make the lasing safety door assembly keep static balance when arm of force level, promptly satisfy G1*R*cosA=G2*r.
As Fig. 6 and shown in Figure 8, when the protective door 5 of lasing safety door assembly was in closing course, protective door moment was: T1=G1*R*cos (A-B).Wherein T1 is a protective door moment, and G1 is a protective door weight, and R is the distance of protective door distance of centre of gravity balance pivot 31, and A is the line of protective door center of gravity and lever 3 fulcrums 31 and the angle of lever 3, and B is the angle of lever 3 and horizontal plane.Balancing weight moment is T2=G2*r*cosB=G1*R*cosA*cosB, and wherein T2 is a balancing weight moment, and G2 is a balancing weight weight, and r is the distance of balancing weight distance of centre of gravity balance pivot 31.
T1/T2＝cos(A-B)/cosA*cosB＝(cosA*cosB+sinA*sinB)/cosA*cosB＝1+sinA*sinB/cosA*cosB
Can draw sinA*sinB/cosA*cosB＜1 by design parameter
So T2＜T1
Therefore, when the lasing safety door assembly is pressed the overbalance state (down push away gently get final product) in state of equilibrium, protective door will be closed under the effect of T1-T2 torque difference automatically, and torque difference keeps always.When no external force acted on protective door, protective door can not be opened automatically.Present embodiment need not to use restriction and locking mechanism, can realize the lasting locking of closed condition.
As Fig. 8 and shown in Figure 9, when the lasing safety door assembly is in full open mode, protective door moment is: T1=G1*R*cos (A+B), wherein T1 is a protective door moment, G1 is a protective door weight, R is the distance of protective door distance of centre of gravity balance pivot 31, and A is the line of protective door center of gravity and lever 3 fulcrums 31 and the angle of lever 3, and B is the angle of lever 3 and horizontal plane.Balancing weight moment is T2=G2*r*cosB=G1*R*cosA*cosB, and wherein T2 is a balancing weight moment, and G2 is a balancing weight weight, and r is the distance of balancing weight distance of centre of gravity balance pivot 31.
At this moment:
T1/T2＝cos(A+B)/cosA*cosB＝(cosA*cosB-sinA*sinB)/cosA*cosB＝1-sinA*sinB/cosA*cosB
Can draw sinA*sinB/cosA*cosB＜1 so T1＜T2 by design parameter
Therefore, when the lasing safety door assembly is faced upward the overbalance state (up push away gently get final product) in state of equilibrium, when the overbalance state is faced upward by mechanism, protective door will be opened under the effect of T2-T1 torque difference automatically, and torque difference keeps always.When no external force acted on protective door, protective door can not be closed automatically.Present embodiment need not to use restriction and locking mechanism, can realize the lasting locking of full open mode.
As shown in figure 10, a kind of laser device comprises the lasing safety door assembly of introducing above.
A kind of laser device, comprise base plate 6, be fixed on supporting element 7, protective door 5, and the protective door 5 of these base plate 6 both sides, also comprise balancing weight 2 and lever 3, described lever 3 first ends are connected with protective door 5, and described balancing weight 2 is between described lever second end and balance pivot 32.
Described laser device also comprises beam 4, and described beam 4 is positioned at described balancing weight 2 belows.
Being placed between described lever second end and the balance pivot of the variable position of described balancing weight.
Described laser device has following design parameter: 0 °＜A≤45 °, and 0 °≤B＜45 ° and B＜A, wherein B is the angle of lever and horizontal plane, A is the line of protective door center of gravity and balance pivot and the angle of lever.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
