Fig. 2 is a structural representation of the present utility model under the energy-stored spring extended state.
Embodiment
To shown in Figure 2, spring energy-storage of the present utility model and relieving mechanism comprise frame 21 as Fig. 1, and frame 21 is provided with trigger equipment, and trigger equipment is connected with holding device and energy storage device, holding device and energy storage device crimping mutually.
As shown in Figure 1, trigger equipment is a cam 1, and cam 1 is connected with energy storage bar 11, and energy storage bar 11 tops are stretched in above the cam 1 and its bottom and stretched below cam 1.
As shown in Figure 1 and Figure 2, holding device comprises pull bar 2, spacing push rod 3, limit spring 10, sincere sub-cam 5 and reduction torsion spring 4, and pull bar 2 is slidingly connected on the frame and with the spacing push rod 3 that is located at its below and is in transmission connection; Spacing push rod 3 is hinged on frame 21 by its axle center 3A; It is right-hand that limit spring 10 is located at spacing push rod 3, limit spring 10 left end hook joints on spacing push rod 3 and its right-hand member hook joint on frame 21; Sincere sub-cam 5 is provided with drift angle 5A and left and right base angle 5B, 5C, and left base angle 5B is hinged on frame 21, drift angle 5A and the crimping mutually of spacing push rod 3; Reduction torsion spring 4 be installed on the frame 21 and with sincere sub-cam 5 tops crimping mutually; Described frame 21 also raises up and is provided with and spacing push rod 3 corresponding alignment pins 9.
As depicted in figs. 1 and 2, energy storage device comprises energy-stored spring 7, spring spacer bar 8, the spring limiting board 6 that left end is fixed together by connecting rod 22, the corresponding chute 23 that is provided with the position of connecting rod 22 on the described frame 21, the rear end of connecting rod 22 is plugged in the chute; The right-hand member hook joint of energy-stored spring 7 is on the nose bar 24 of frame 21 right-hand members; The bottom of the right-hand member of spring spacer bar 8 and described energy storage bar 11 is hinged; Spring limiting board 6 is provided with bayonet socket 6A at right-hand member, and the limit on the left position of bayonet socket 6A is corresponding with the position of the right base angle 5C of sincere sub-cam 5.Wherein, when energy-stored spring 7 was positioned at the limit on the left position, limit spring 10 was in tension.
The utility model is divided into two stages at work, i.e. energy storage and maintenance stage and release stage.
In energy storage and maintenance stage, as Fig. 2 and shown in Figure 1, dextrorotation rotating cam 1, cam 1 drives together rotation of energy storage bar 11, the lower end of energy storage bar 11 promotes spring spacer bar 8 to left movement, left end and spring limiting board 6 that the connecting rod 22 that spring spacer bar 8 is connected by left end drives energy-stored spring 7 are moved to the left the limit on the left position along chute 23, and energy-stored spring 7 is stretched and storage power; This moment, the bayonet socket 6A on the spring limiting board 6 moved to the corresponding position of right base angle 5C with sincere sub-cam 5, the space that right base angle 5C so acquisition move downward, sincere sub-cam 5 turns clockwise around its pin joint left side base angle 5B under the downforce effect of reduction torsion spring 4, make right base angle 5C fall into bayonet socket 6A, simultaneously drift angle 5A moves downward and unclamps roof pressure to spacing push rod 3 bottoms.Spacing push rod 3 can't not rotate when being unclamped by drift angle 5A in its bottom, unclamping the spacing push rod 3 in back moves right at the shrinkage direction of the contraction lower edge of limit spring 10 limit spring 10, drive pull bar 2 simultaneously and together move right, be positioned up to the bottom of spacing push rod 3 that pin 9 blocks, the right-hand member of pull bar 2 also just roof pressure on the projection of the top of cam 1.The drift angle 5A roof pressure of the lower end of spacing push rod 3 and sincere sub-cam 5 together at this moment, spacing push rod 3 and reduction torsion spring 4 together apply downward pressure to sincere sub-cam 5, thereby stop sincere sub-cam 5 to rotate up counterclockwise, so just block limiting plate 6 it also can not spurred to the right by energy-stored spring 7 behind the cam 1 that stops the rotation, kept cam 1 to pass to the energy of energy-stored spring 7.
In the release stage, as depicted in figs. 1 and 2, be rotated counterclockwise cam 1, the top projection pushing drawing rod 2 of cam 1 is together to left movement, the upper end that pull bar 2 drives spacing push rod 3 overcomes the convergent force of limit spring 10 to left movement, spacing push rod 3 is rotated counterclockwise around its axle center 3A, and the bottom of spacing like this push rod 3 will move upward to the right, thereby loosen the roof pressure to sincere sub-cam 5.Under the contraction of energy-stored spring 7, the bayonet socket 6A of spring limiting board 6 overcomes the downforce of 4 pairs of sincere sub-cams 5 of reduction torsion spring, with the right base angle 5C of sincere sub-cam 5 jack-up that makes progress, thereby energy-stored spring 7 is shunk rapidly, and stored energy abrupt release is come out.
