The vertical pushing force and/or pulling force sensing mechanism 109 respectively detects the pushing force and/or pulling force and the bottom pushing force and/or pulling force on the top retractable plate and the bottom retractable plate through a sensing principle; when sealing is needed, the vertical electric push rod controls the vertical telescopic mechanism to respectively control the top telescopic plate and the bottom telescopic plate to slowly extend outwards until the top thrust force and/or the pulling force and the bottom thrust force and/or the pulling force respectively reach the preset thrust force and/or pulling force value, and the outward extension is stopped; when the sealing needs to be relieved, the vertical electric push rod controls the vertical telescopic mechanism to respectively control the top telescopic plate and the bottom telescopic plate to retract inwards until the vertical pushing force and/or pulling force sensing mechanism 109 senses that the pushing force and/or pulling force parameter value reaches a set value, and the vertical electric push rod control device is characterized in that the electric push rod can be prevented from being overloaded due to excessive retraction, the electric push rod is damaged, or the service life of the electric push rod is shortened. The vertical telescopic mechanism is specifically a top lever push rod structure and a bottom lever push rod structure, the top lever push rod structure is the same as the bottom lever push rod structure, the top lever push rod structure comprises a top fulcrum 104 and a top lever 103, the top fulcrum is fixed on the inner side of a top frame 106, one end of the top lever 103 is connected with a fixed edge B of a top telescopic plate through a communication rod 102, the communication rod 102 is connected with the end part of the top lever 103 through a rotating shaft and/or a bearing, the other end of the top lever 103 is connected with a top push rod 107 vertically arranged inside a side edge of a partition screen, the top push rod is connected with a vertical electric push rod 110 through a vertical switching mechanism, and a vertical thrust and/or tension sensing mechanism 109 is arranged on the vertical switching mechanism. The vertical electric push rod 110 adopts a micro-motor direct push rod, and the vertical push force and/or pull force sensing mechanism adopts a push force and/or pull force sensor. The vertical electric push rod 110 is controlled to push the ejector rod 107 to move up and down, so as to drive the ejector rod 103 to rotate, and further drive the ejector expansion plate fixed at one end of the lever to move inwards or outwards. When the screen door moves to a preset position, roller hanging feet A1 and A2 are arranged at the top of the screen door, and a power supply wire of a circuit system B1 arranged in the screen door is connected with a power supply point arranged at a fixed position at the top by penetrating through the roller hanging feet A1 and/or A2, so that power supply is realized. The sealing device can automatically perform the up-and-down sealing action after the power supply is switched on, and can also perform the sealing operation by being triggered by a key or other modes.

The insulating fixed main seat is in a boat shape as a whole, the middle part of the insulating fixed main seat, namely the part provided with the groove, is protruded downwards, and one side or two sides of the insulating fixed main seat are provided with conducting strips extending to the lower surface, and the conducting strips are electrically connected with the wire connecting lugs; the conductive elastic sheet is matched with the insulating fixed main seat, covers the bottom of the bulge of the insulating fixed main seat and is electrically connected with the conductive sheet. The whole conductive elastic sheet is provided with an arc-shaped connecting lug in the middle, the connecting lugs on two sides can be respectively fixed with an insulating end plate through hollow rivets, and the insulating end plates are fixed on an insulating fixing main seat through fastening screws, so that a complete rail top electric connector is obtained. The power supply line is connected from the top and is electrically connected with the conductive elastic sheets of which the two ends are both arc-shaped. The two ends of the conductive elastic sheet, namely the running direction of the guide rail, are in an arc shape, so that the screen top electric connector can conveniently move.

The screen top electric connector which is arranged in a matching way is arranged on the hollow hanging wheel screw and mainly comprises a hollow hanging wheel screw 1106, an inner conducting dielectric piece 1105A, a convex top electric connection contact 1102, a top contact spring 1103, an inner movable contact 1104 and an insulating screw locking end 1101, wherein the whole middle of the hollow hanging wheel screw 1106 is through, one end of the hollow hanging wheel screw is provided with an external thread, the other end of the hollow hanging wheel screw is provided with an internal thread, the internal diameter of the end provided with the internal thread is larger, and a cavity for installing the convex top electric connection contact 1102 is formed inside the hollow hanging wheel screw; the conducting wire 1105 with outer insulating layer electrically connected with the inner part of the screen door passes through the hollow hanging wheel screw to be electrically connected with the inner conducting intermediate plate 1105A, and is pressed into the cavity after being arranged on an insulating plastic seat; the convex top electric connection contact 1102 is a top electric connection pile with one end provided with a spherical surface or a cambered surface, the other side of the top electric connection pile is connected with an inner movable conductive intermediate sheet 1104 through a flexible lead, a top contact spring 1103 is arranged between the inner movable conductive intermediate sheet 1104 and the convex top electric connection contact 1102, a through hole matched with the convex top electric connection contact 1102 is arranged in the middle of an insulating screw locking end 1101, and a convex part of the convex top electric connection contact 1102 can partially freely extend out of the through hole. The entire structure ensures that the wire is highly insulated from the hollow trolley screw by pressing the convex jacking connection point against the end of the hollow trolley screw 1106 by the insulating screw locking head 1101, and the convex jacking connection point only partially protrudes out of the hollow trolley screw due to the restriction of the insulating screw locking head 1101 and the action of the jacking spring 1103; when an external force presses the convex top electrical connection contact point, the driving top contact spring 1103 can be retracted inward. The insulating screw locking end 1101 is an insulating screw member made of engineering plastics with high insulating property and high strength, a round hole is formed in the middle of the insulating screw locking end 1101, and two specially designed blind holes are formed in the insulating screw locking end 1101, so that an installer can conveniently lock the insulating screw locking end 1101 at the center of the screw head of the hollow hanging wheel screw. 1105 is that the exposed copper wire after the outer insulation layer of the conductive wire with the outer insulation layer is stripped off is fixed with the inner conductive interface 1105A of copper, and then is connected into a whole by soldering and cooling; the inner diameter of the through hole in the center of the hollow hanging wheel screw is larger than the outer diameter of the conductive wire with the outer insulating layer, and when the screen is produced and installed, before the hollow hanging wheel screw is rotated and adjusted, the conductive wire with the outer insulating layer is not tensioned, the inner movable inner conductive intermediate piece 1105A and the conductive wire with the outer insulating layer cannot rotate along with the hollow hanging wheel screw, and the special design ensures that the inner movable conductive intermediate piece and the conductive wire with the outer insulating layer cannot be twisted and damaged when workers adjust the height of the screen by using the rotation of the hollow hanging wheel screw; basically, the conductive wire is tightened after the adjustment, and then if the screw needs to be rotated for a little adjustment, the inner conductive interface 1105A will slip and will not rotate with the screw basically.

It is described in particular that the drawing of the conductive elastic sheet is provided with a special curved surface, which is a curved surface composed of nearly parallel parabolas, and the law of acting force equal to reaction force is skillfully and fully utilized, so that a novel and practical effect is produced: the two sides of the conductive elastic sheet made of wear-resistant materials are respectively provided with an inclined plane, the center of the conductive elastic sheet is provided with a suspended large arc plane, the large arc plane is formed by a plane and the top parts of the left and right curved surfaces formed by nearly parallel parabolas in a tangent mode, the other end of the curved surface formed by nearly parallel parabolas is connected with the other end of the curved surface in a seamless and smooth mode through an arc surface tangent to the large arc plane, and the other end of the arc surface is connected with the inclined plane tangent to the large arc plane in a seamless and smooth mode; the design of the special curved surface of the large arc-shaped plane makes the conductive elastic sheet generate slow gradient change towards the direction of the insulating end plate at the position far away from the center, so that the space of elastic movement can be slowly increased, and simultaneously, the thrust force of the interaction between the convex top electric connection contact and the conductive elastic sheet can be slowly increased, so that when the convex top electric connection contact and the contact point of the conductive elastic sheet move, the impact force can be relieved when mutual pushing is generated, violent thrust force and/or tension force change can not be generated, and the service life of the convex top electric connection contact and the conductive elastic sheet is prolonged.

The elastic strain is utilized to generate elastic force to enable the conductive elastic sheet and the convex top electric connection contact point to be in close contact: when the convex top electric connection contact point slides in the direction of the center of the conductive elastic sheet, because the highest point of the convex top electric connection contact point is higher than the lowest point of the conductive elastic sheet, after the convex top electric connection contact point is contacted with the conductive elastic sheet, the contact points of the convex top electric connection contact point and the conductive elastic sheet can continuously generate movement of position change along with the movement of the universal wheel, and the movement curve of the contact points is limited by the curved surface which is formed by nearly parallel parabolas on the conductive elastic sheet, so that the convex top electric connection contact point generates corresponding displacement, and the convex top electric connection contact point is connected with the highest point; the contact point of the convex top electric connection contact point and the conductive elastic sheet is formed; the conductive elastic sheet can generate elastic strain to generate elasticity by the displacement, and the impact force generated when the convex top electric connection contact slides in can be buffered; the elastic displacement of the conductive elastic sheet also causes the acting force generated towards the convex top electric connection contact point in the vertical direction, so that the convex top electric connection contact point is pressed, the convex top electric connection contact point generates corresponding displacement along the central line of the hollow hanging wheel screw, the spring of the convex top electric connection contact point also generates compression deformation along the central line direction of the hollow hanging wheel screw, and the elastic strain of the spring generates elastic force, so that the convex top electric connection contact point and the conductive elastic sheet generate mutual pushing force, thereby ensuring that the contact point between the convex top electric connection contact point and the conductive elastic sheet can always have force to enable the convex top electric connection contact point and the conductive elastic sheet to be tightly contacted together during the use period, and ensuring that the circuit can be always connected during the use period.

Because the lateral contact points are all vertically contacted and do not need to transversely move relatively, the electric connection contact points in the vertical direction only need to have certain elastic stroke. The side input connector specifically comprises a side-in insulating box body 2002, a side-in metal contact 2004 and a side-in spring 2003, wherein two through holes are formed in the side-in insulating box body, and a plurality of side-in metal contacts can be connected as required.

During installation, the side entry spring is sleeved from the small end and pressed into the through hole, the small end overcomes the elasticity of the spring and extends out of the other side of the through hole, the spring clamp spring is pressed into the through hole, the wiring through hole is connected with the upper conducting wire, and then the base rice screw 2004C is locked to lock the conducting wire. The side output connector is identical to the side input connector in structure principle. After the installation is finished, the side metal contacts of the rear side output connector and the side input connector protrude outwards under the elastic force of the springs, and are limited by the spring snap springs; when two adjacent screen doors are touched together, the side metal-in contact and the side metal-out contact are both pushed and/or pulled, the side metal-in contact and the side metal-out contact are compressed inwards by overcoming the elasticity of the spring, the small end does not extend inwards continuously, and the reliable contact of the side metal-in contact and the side metal-out contact is ensured due to the action of the spring.

The unlocking action of the left first screen air door and the second screen air door in the picture 20 is that the control circuit board controls the synchronous starting action of the control circuit board until the second screen door can be moved away, so that the power supply can be ensured to be continuous, and the phenomenon that the first screen air door cannot be moved due to the fact that the connection of one electrode is lacked and no power is supplied after the second screen door is moved away can be avoided.

The Y-shaped rail structure is characterized in that a straight rail material is cut into main components of the Y-shaped rail structure, and then a steel connecting component is used for connecting the main components into the Y-shaped rail structure.

Two branches of the Y-shaped track are specifically a first branch and a second branch, and the first branch and the second branch are combined into the same single track through 3 sections of lines. And rail top electric connectors matched with each screen door are arranged on the partition working area, each group of rail top electric connectors are connected in parallel, and two top electric connecting piles connected with two power supplies on the rail top electric connectors are connected with the first power supply. The Y-shaped rail and the partition working area are in right-angle transition, bent angle transition or field-shaped transition. In this state, all the screen doors are stored in the rail storage area LC, and due to the limitation of space, the screen doors may be stacked obliquely, so that the storage can be realized only by making the distance L1 between the center lines of the two ends of the storage rail the same as the distance L2 between the center lines of the two hanging legs of the screen door to be hung. The screen door is moved one by one from the storage area LC to the partition working area LA for single-need unfolding use. Fig. 7 is a schematic view of the movable screen door turning to the first state, moving the screen door M4 toward the partition working area LA, and when the screen door M4 is moved to be unable to move horizontally, moving one side of the screen door M4 toward the partition working area LA first, and gradually driving the other side to slide toward the partition working area LA, which is equivalent to changing to one direction; fig. 8 is a schematic view of the movable screen door turning to the second state, one side of the screen door M4 enters into the partition working area LA and gradually drives the other side to slide into the partition working area LA completely, and fig. 9 is a schematic view of the single movable screen door moving in place;

and moves the damper door M4 fully to the preset position. As shown in fig. 10, all of the moving screen dampers are moved into position, moving all of the screen dampers one by one into the blocked operating area LA. FIG. 11 is a schematic view showing a sealing state in which the vertical and horizontal sealing operations are automatically or manually started after all the screen doors are moved in place, and all the side expansion plates and the top expansion plate are extended and automatically controlled to achieve the sealing state. FIG. 12 is a schematic view of the unsealing state, when it is necessary to remove the screen door, the unsealing is started first, and the control of all the side expansion plates and the top expansion plate to retract into the screen door is automatically realized, so that the freely movable screen door can be restored.

And a rail top electric connector matched with each screen door is arranged on the partition working area, two top electric connecting piles are arranged on the rail top electric connector, and the top electric connecting piles are connected with a first power supply. Two branches of the Y-shaped track are specifically a first branch and a second branch, and the first branch and the second branch are combined into the same single track through 3 sections of lines. Partition interval both ends or an alternative and be equipped with the stand, be equipped with a set of side post electric connector on the stand, be equipped with two side electricity connecting pile on the side post electric connector, side electricity connecting pile is connected with second power supply. The inside of top electricity connection stake is equipped with the spring, top electricity connection stake inwards contracts when receiving external force extrusion.

Because the scheme is completely free of the expansion plate operator and the expansion plate transmission member, the area of the visible window can be greatly increased in the occasion of being applied to the glass screen, the appearance is improved, the light transmission area is increased, the utilization rate of light resources is increased, and the concept of environmental protection is met. By adopting the Y-shaped rail, when the hanging wheel system moves, the screen can easily finish horizontal and universal direction change along with the hanging wheel, including right-angle direction change, left-falling curve direction change and Chinese character tian-shaped direction change, so that the screen air door can be easily pushed to any set position, and even the operation can be finished by only one hand; a hanging wheel system of a novel hollow hanging wheel screw which is particularly ingenious innovatively designs a power supply system component supplied with power by a vertical circuit; replace the common solid hanging wheel screw system; two power supplies can be selectively selected and supplied with different voltages simultaneously, and the power supplies are supplied in the vertical direction and the side direction simultaneously, a special electric brush structure is arranged at the top of a screw through a hollow hanging wheel screw, and a conductive elastic copper sheet component is arranged at a corresponding position in a track, so that the power supply can be reliably and vertically obtained at any set position of the universal movement of the screen to supply the air door of the glass movable partition screen; when two screen air doors are combined and closed and then powered on, the side expansion plate and the top expansion plate can automatically extend and press the sealing rubber strip under the set thrust and/or tension condition to achieve the sound insulation effect, when one of the two adjacent screens is pushed away, the side expansion plate and the top expansion plate of one screen beside the adjacent screen can automatically retract together with the pressed sealing rubber strip under the set thrust and/or tension condition to enable the screen to easily move, so that the screen can be easily operated by a general adult and even a small person can move; the vertical power supply system is adopted, so that the movable glass partition screen can be installed and used in any set position in a field or space without a wall or a fixed upright post, and the electric control system is utilized to finish the action of automatically stretching and tightening or loosening the movable glass partition screen; and the circuit is used during power failure and short stroke circuit faults and motor faults: the positioned and tightly supported screen door can be easily removed after being loosened by loosening one screw; the potential safety hazard that the motor cannot move without power supply and indoor personnel cannot enter and exit in time is avoided. After the emergency safety system is used, the reset can be completed only by powering on again and then locking the screw; the concept that a user operates the telescopic plate operator each time is completely abandoned, the telescopic plate operator is changed into an electric telescopic structural member, the size of the pushing force and/or the pulling force when the telescopic plate is tightened and loosened is set once according to the requirement of a client when a product is produced, the pushing force and/or the pulling force is irrelevant to the telescopic length, and the sealing effect can be fully generated without adjusting the pushing force and/or the pulling force or the telescopic length when the telescopic plate is tightened and loosened each time; the problem of non-uniform ground level is solved, when the ground level of each screen is different; the stretching and retracting can be automatically adjusted without adjusting the pushing force and/or the pulling force or the stretching length each time when the stretching and releasing are performed according to the fact that the set pushing force and/or the pulling force during the stretching and releasing are independent of the stretching length, and the stretching component can stop acting after the expected force effect of the pushing force and/or the pulling force during the stretching and the releasing is achieved; therefore, in a microscopic range, when the sealing plastic strip and the mechanical component pass through a non-uniform horizontal or vertical surface, the compensation effect can be automatically generated, and the set force can be automatically achieved; the problems of non-uniform ground level and insufficient verticality of a vertical surface are perfectly solved; even if the ground and the horizontal plane of each screen are different and the verticality of the vertical surface is not enough, the screen can be tightly supported and sealed without adjustment; thereby preventing the generation of a gap and effectively preventing the reduction of the sound insulation effect. Because a push-pull thrust and/or pull force control system is used, in a microscopic range, when the sealing plastic strip and a mechanical component meet an irregular surface, a compensation effect can be automatically generated due to the set push-pull force, and the action is stopped until the set force is reached, so that the condition that the gap is not well sealed is prevented, and the reduction of a sound insulation effect can be effectively prevented; the screen door is powered by low-voltage power supply, and the multi-path power supply system is arranged, so that a low-voltage backup battery or UPS (uninterrupted power supply) equipment with higher safety can be selectively arranged at different positions to supply a backup power supply, and when a fire disaster or a natural disaster power failure occurs, the movable partition screen can be normally moved away, an escape passage is easily expanded, and the time for evacuating and escaping people in the field is saved.

When the screen door moves to the right position, the vertical sliding adjustment fastener 2519 of the ground pin is pulled downwards to drive the screen door positioning ground pin 2521 to be inserted into a ground pin hole which is preset and matched on the ground, so as to prevent the screen air door from moving; when the sealing operation is triggered, the vertical electric push rod 2510 is automatically controlled to pull the top push rod 2506 downwards, the bottom push rod 2511 is pulled upwards corresponding to bottom sealing, the middle lever 2504 rotates clockwise, the top expansion plate is pushed out towards the top, when the top expansion plate is collided with the top surface, the top surface is pressed upwards, the downward pulling force of the corresponding vertical electric push rod 2510 is increased, and therefore the pushing force and/or the pulling force of the top expansion plate towards the top can be obtained actually by detecting the pulling force of the pushing force and pulling force sensing mechanism 2509. The magnitude of a top thrust threshold value is set in advance according to the required sealing degree, the magnitude of the tension of the thrust and tension sensing mechanism 2509 is monitored and detected, and when the detected tension of the thrust and tension sensing mechanism 2509 reaches or exceeds the preset top thrust threshold value, the vertical electric push rod 2510 is immediately controlled to stop working, namely the current screen reaches the preset sealing degree. The extending amount is automatically controlled by monitoring the pushing force and/or the pulling force of the top, and the extending amount is not fixedly controlled, so that the system automatically meets the sealing requirement according to different horizontal conditions. Also the sealing of the bottom is the same control principle. Correspondingly, if the structure mode is adopted, the side sealing with the same structure can be added when the side surface has the sealing requirement.

FIG. 24 is a schematic view of a roller hanger; AA is a side sectional view, BB is a front sectional view, and CC is a top sectional view. The roller hanging foot is a novel roller hanging foot with a special structure; the roller hanging foot 15-1 mainly comprises an anti-rotation inserting piece 15-2, a tension spring 15-3, a locking screw 15-4, a smoothing medium 15-5, a spring medium 15-6 and a locking nut 15-7; the roller hanging foot has the functions of hanging a screen through a hollow screw, and is additionally and innovatively provided with a rotation preventing insertion sheet 15-2, wherein the inner side of the rotation preventing insertion sheet 15-2 is provided with a narrow parallel long slotted hole at one side close to a locking screw 15-4, the width of the parallel long slotted hole is only slightly larger than the distance of the opposite side of the square section of the middle section of the hollow screw, and the width of the parallel long slotted hole is gradually widened to be slightly larger than the outer diameter of the hollow screw by a small circular angle at the position far away from the locking screw 15-4; when the novel power supply system is used, a worker pushes the tail end of the parallel long groove of the rotation preventing inserting piece 15-2 to the direction of the thread center line along the horizontal direction to the end and keeps a pushing state, at the moment, the tension spring 5-3 with the pre-tensioning force is stretched, the tension force is correspondingly increased, the parallel groove hole on the inner side of the rotation preventing inserting piece 15-2 also slides to the end, meanwhile, the screw center line of the roller hanging foot falls at the corresponding position where the width of the parallel long groove hole is slightly larger than the outer diameter of the hollow screw, the worker can easily lock the hollow screw into the roller hanging foot, when the hollow screw is rotationally locked to a proper set position, the worker loosens the pushed rotation preventing inserting piece 15-2, the tension force of the tension spring 5-3 can pull the rotation preventing inserting piece 15-2 back to the original position, the narrow part of the parallel long groove hole can clamp the middle section of the hollow screw, so that the hollow screw cannot rotate, and therefore the height (or the pushing force and/or the tension force) of the top contact of the screw on the screen roller hanging foot can be prevented from being connected with electricity, and the power supply system can be greatly stabilized.
