Fig. 1 and 2 show an adjustable switch-off spring structure of an inflatable cabinet, which includes a cam 1, a spring 5 and a base 2, wherein the base 2 is disposed on a mounting plate on an inner wall of a cabinet 7, the base 2 is provided with a vertical shaft 21, the vertical shaft 21 is provided with a slider 22, the slider 22 can slide up and down on the vertical shaft 21, the cam 1 is also disposed in the cabinet 7, the cam 1 is connected to an external operating mechanism through a transmission shaft, the external operating mechanism rotates the cam through a rotating shaft, the external operating mechanism is a handle or an energy storage transmission mechanism, the energy storage transmission mechanism can be an electric energy storage transmission mechanism or a manual energy storage device, which is a conventional component in the field, and the detailed connection mode is not described again, and a VD4 circuit breaker energy storage motor produced by shanghai mo electric science and technology limited company can be adopted;

the spring 5 is horizontally arranged, one end of the spring 5 is sleeved with the first mounting block 4, the cross section of the first mounting block 4 is in a cross shape, and the other end of the spring 5 is sleeved with the compression amount adjusting device 6;

a linkage device 3 is arranged among the first mounting block 4, the sliding block 22 and the cam 1, and the linkage device 3 has the structure that: a first crank arm 31 is hinged to the slider 22, the other end of the first crank arm 31 is fixed to a first shaft sleeve, the first shaft sleeve is sleeved on a first rotating shaft 33, the first shaft sleeve can rotate on the first rotating shaft 33, the first rotating shaft 33 is fixed to the inner wall of the cabinet 7, a second crank arm 32 and a third crank arm 34 are hinged to the first shaft sleeve, the upper end of the second crank arm 32 is hinged to the first mounting block 4, the lower end of the third crank arm 34 is hinged to a connecting rod 35, the lower end of the connecting rod 35 is hinged to a fourth crank arm 36, the fourth crank arm 36 is sleeved on a second rotating shaft 37, the fourth crank arm 36 can rotate on the second rotating shaft 37, the second rotating shaft 37 is fixed to the inner wall of the cabinet 7, the other end of the fourth crank arm 36 is connected with a driving shaft of a movable contact in an embedded pole through a crank arm embedded pole rotating linear driving mechanism, the embedded pole is a conventional part in the field, specific structure and principle are not repeated, the crank arm rotating linear driving mechanism is a conventional technology in the field, for example, a transmission mechanism provided by the limited tianhei high electric company for converting rotation into intelligent linear motion is not repeated;

the compression amount adjusting device 6 has the structure: including second installation piece 61 and threaded rod 62, second installation piece 61 one side meets with spring 5, and second installation piece 61 cross-section is the T style of calligraphy, and the opposite side of second installation piece 61 is equipped with threaded rod 62, and threaded rod 62 wears out the shell of rack 7, passes through first threaded connection between rack 7 shell and the threaded rod 62.

When the switch is switched on, the cam rotates clockwise through the external operating mechanism, and then the first connecting lever 31 is hit, the first connecting lever 31 rises along the vertical shaft and rotates anticlockwise, the third connecting lever 34 fixed on the same shaft sleeve with the first connecting lever 31 also rotates anticlockwise, the third connecting lever 34 drives the connecting rod 35 to descend, the connecting rod 35 drives the fourth connecting lever 36 to rotate clockwise, and then the fourth connecting lever 36 is driven to output outwards, the driving rod is pushed, the purpose of driving the moving contact and the static contact in the solid-sealed pole is achieved, meanwhile, the spring 5 can generate rebounding force on the second connecting lever 32, as the first connecting lever 31 and the second connecting lever 32 are fixed on the first shaft sleeve, the rebounding force can be transmitted to the cam through the first connecting lever 31, and then resistance is generated on the driving rotating wheel.

The compression amount of the spring 5 is adjusted by rotating the threaded rod 62, and the threaded rod 62 is rotated inwards, wherein the compression amount is larger, so that the larger the rebounding force of the spring 5 is, the larger the force value required for driving the rotating wheel is, namely, the larger the brake closing force is.

During the switching-off, make the cam not contact with first connecting lever 31 through outside operating device, then spring 5 can drive second connecting lever 32 clockwise rotation, and third connecting lever 34 also clockwise rotation, and third connecting lever 34 drives connecting rod 35 and rises, and connecting rod 35 drives fourth connecting lever 36 clockwise rotation, and then drives fourth connecting lever 36 and inwards exports, and the pulling moving contact separates with the static contact, and the compression volume is big more, and the power of spring 5 bounce-back is big more like this, and the switching-off speed is fast more.

And universal parts are adopted, so that different individualized requirements are met, the assembly efficiency is improved, and the purchase cost is reduced.

Example 2

Referring to fig. 3 and 4, the threaded rod 62 in this example is divided into an inner threaded rod 622 and an outer threaded rod 621, the outer threaded rod 621 is connected to the housing of the cabinet 7 through a first thread, the inner threaded rod 622 is connected to the outer threaded rod 621 through a second thread, the pitch of the second thread is smaller than that of the first thread, and one end of the inner threaded rod 622 extends into the cabinet 7 and is connected to the second mounting block 61.

Because the pitch of the second screw thread is less than that of the first screw thread, the radial speed of the rotating inner screw 622 can be less than that of the rotating outer screw 621, so that the compression amount can be quickly adjusted by rotating the outer screw 621, the compression amount can be accurately adjusted by rotating the inner screw 622, and the purpose of accurately adjusting the opening and closing force value is achieved.

Referring to fig. 5, it can be further optimized that a fastening nut 63 is sleeved on the outer screw 621, so that the outer screw 621 is prevented from moving when the inner screw 622 is adjusted, and the stability of adjustment is ensured.
