As shown in fig. 1 and 2, a floor spring balance door comprises two vertically arranged door frames 1, wherein axially arranged cavities are arranged in the door frames 1; a vertical main shaft 2 is arranged in one door frame 1, a door body 3 is arranged between the two door frames 1, the upper edge of the door body 3 is hinged to the upper end of the main shaft 2 through an upper connecting piece 4, and the lower edge of the door body 3 is hinged to the lower end of the main shaft 2 through a lower connecting piece 5.

With reference to fig. 1 to 3, the top of each of the two door frames 1 is provided with a horizontal upper beam 6, the bottom surface of the upper beam 6 is provided with an axially arranged rail 61, and the bottom surface of the upper beam 6 is further provided with a spindle bearing position 62 for inserting the spindle 2; a sliding block 63 capable of moving along the track 61 is arranged in the track 61, one side of the sliding block 63 is formed into a cambered surface matched with the guide wheel 32, and an energy storage spring 64 is arranged between the other side of the sliding block 63 and the tail end of the track 61.

Referring to fig. 4, the upper connecting member 4 includes an upper arm 41 perpendicular to the main shaft 2, and one end of the upper arm 41 is fixedly sleeved on the main shaft 2; an upper door shaft 42 parallel to the main shaft 2 is arranged at the position of the upper support arm 41 close to the other end; the lower connecting piece 5 comprises a lower supporting arm 51 vertical to the main shaft 2, and one end of the lower supporting arm 51 is fixedly sleeved on the main shaft 2; the lower arm 51 is provided with a lower door shaft 52 parallel to the main shaft 2 at a position near the other end.

As shown in fig. 5, a vertical wheel axle 31 is arranged on the upper edge of the door body 3, and a guide wheel 32 matched with the rail 61 is arranged on the wheel axle 31 in a penetrating way; the upper edge of the door body 3 is formed with a step matched with the upper supporting arm 41, and the step of the upper supporting arm 41 is provided with an upper door shaft bearing position 33 for inserting the upper door shaft 42.

Referring to fig. 6, the lower edge of the door body 3 is formed with a step engaged with the lower arm 51, and the step of the lower arm 51 is provided with a lower door shaft bearing position 34 into which the lower door shaft 52 is inserted.

Referring to fig. 2 and 7, the bottom surface of the lower arm 51 is provided with an accommodating cavity 53, and the torsion arm of the floor spring 7 is fixedly disposed in the accommodating cavity 53.

In practical application, due to the structural reason of the balance door, when the door leaf is opened to the maximum angle of 90 degrees from inside to outside, the rotation angle of the floor spring is only about 45 degrees, and the characteristic of bidirectional opening of the floor spring can be fully utilized. However, the actual rotation angle of the floor spring is small, the force provided by the floor spring cannot ensure that the door leaf can be directly driven to move and close automatically when the door leaf is at the limit angle, and the characteristic of automatic door closing of the floor spring cannot be fully utilized; when the door body is too high and too large, the problem is more prominent because of the increase of the self weight of the door. Therefore, a sliding block and an energy storage spring mechanism are required to be added on the basis of the existing guide rail of the upper cross beam. The mechanism has the functions of 1) providing certain buffer when the door leaf is opened, and preventing the door leaf from opening at an overlarge speed; 2) when the door leaf is closed, the guide wheel is pushed to move, an initial force is provided for closing the door leaf, and then the door leaf is driven to move to assist the floor spring to close the door; 3) the forces generated by the two actions are adjusted to protect the relevant structures.

Referring to fig. 8-12, the working process of the present application is as follows:

when a pedestrian pushes the door body (fig. 10 → fig. 9), the guide wheel driven by the door body moves rightwards in the guide rail, and simultaneously the upper door shaft and the lower door shaft move outwards to further drive the support arm and the main shaft to rotate anticlockwise, so that the door body is opened inwards under the combined action of the parts. When the door body is opened inwards to 50 degrees (figure 9), the guide wheel is contacted with the sliding block, the sliding block drives the energy storage spring to compress, certain buffering is carried out on the side-by-side door, and the excessive door opening speed is prevented. When the sliding block slides to the final position (figure 8), the door body reaches the inward maximum opening angle of 90 degrees, the guide wheel reaches the limit position to limit the door leaf, and the door leaf stops moving.

When a pedestrian pulls the door body (fig. 10 → fig. 11), the guide wheel driven by the door body moves rightwards in the guide rail, and meanwhile, the upper door shaft and the lower door shaft move inwards to further drive the support arm and the main shaft to rotate clockwise; under the combined action of the parts, the door body is opened outwards. When the door body is opened outwards to 50 degrees (figure 11), the guide wheel is contacted with the sliding block, the sliding block drives the energy storage spring to compress, certain buffering is carried out on the side-by-side door, and the excessive door opening speed is prevented. When the sliding block slides to the final position (figure 12), the door body reaches the outward maximum opening angle of 90 degrees, the guide wheel reaches the limit position to limit the door leaf, and the door leaf stops moving.

After the pedestrian passes through the ground spring, the ground spring drives the support arm and the main shaft to rotate, the energy storage spring pushes the sliding block to enable the guide wheel to move leftwards, the door body returns to the initial position (figure 10) under the combined action, and the door is stopped at the initial zero position under the action of the ground spring, so that the door body is automatically closed.

Compared with the traditional floor spring door, the door opening torque is reduced by reducing the turning radius of the door body through the main shaft, the upper support arm and the lower support arm, so that the door opening is more labor-saving.

It should be understood that the above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, so that the equivalent changes and modifications made in the light of the above disclosure and the appended claims are all within the scope of the present invention.
