Description

Technical Field

[0001] The invention relates to a side-sliding anti-theft door. Background Art

[0002] Security doors are essential for indoor theft prevention. For smaller buildings, such as those in residential buildings, a swing-opening security door is typically used at the entrance. However, for factory buildings, where equipment needs to be moved in and out, the entrance is larger. Traditional swing-opening security doors offer poor user experience and require a larger area to open.

[0003] Therefore, the use of side sliding doors for anti-theft protection of entrances can greatly reduce the occupation of internal space in the factory area. However, the anti-theft effect of side sliding doors in the prior art is poor. The reason is that the structure of side sliding doors is different from that of doors that rotate to open, and traditional latch-type locks cannot be locked.

[0004] Therefore, the mainstream anti-theft method for side sliding doors is to weld lock rings on the surface of the side sliding door and the surface of the door frame, and lock it by combining the lock ring with a chain. In this locking method, the locking position is outdoors, and the locking position can be easily destroyed by tools such as wire cutters, leading to theft.

[0005] To this end, we have designed a side-sliding anti-theft door that can be locked without a lock and cannot be pushed open maliciously. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a side-sliding anti-theft door which can be locked without a lock and cannot be pushed open maliciously.

When the hydraulic jack is extended, the sliding door is jacked up through the cooperation of the force inclined surface and the force groove, and the bottom of the sliding door is off the ground; an oil cylinder and an oil pump for supplying oil to the hydraulic jack are installed at the upper end of the frame, and a connecting pipe is installed at the oblique angle of the frame, and the driving device is cooperated through the connecting pipe.

[0011] Preferably, a wheel groove matching the pulley is provided on the top of the bracket plate, the two ends of the wheel groove are closed, and a guide groove for draining the lubricating fluid is processed on the side of the wheel groove. The guide groove passes through the direction of the sliding door, and the lubricating fluid in the wheel groove acts on the sliding door after passing through the guide groove, so that the resistance of the sliding door when sliding along the bracket plates on both sides is reduced.

[0012] Preferably, a groove is provided at the end face of the bracket plate which acts on the sliding door, a rubber strip is embedded at the bottom of the groove, a recovery hole is passed through the side of the bracket plate, and excess lubricating fluid flows down the bracket plate and is intercepted by the rubber strip and discharged through the recovery hole, and a groove plate is provided on the inner side of the bracket plate, and the lubricating fluid discharged through the recovery hole flows into the groove plate.

[0013] Preferably, the driving device includes two wheel axles, a bearing seat is provided between the wheel axles and the door frame, two wheel discs are provided on the outside of each wheel axle, and a wheel groove is provided on the outside of the wheel disc. A traction rope is provided between the wheel axles on both sides through the wheel disc, and the traction rope passes through the connecting pipe, and the connecting pipe is fixed to the traction rope.

Therefore, they should not be understood as limiting the present invention.

[0034] In addition, in the description of the present invention, “a plurality of” means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0035] In the present invention, unless otherwise expressly specified or limited, terms such as "disposed," "socketed," "connected," "through," and "inserted" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise expressly specified or limited. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] See Figure 1The side-sliding anti-theft door shown includes a door frame 1, and a fixed door panel 101 is arranged parallel to the inner side of the door frame 1, and a sliding groove 102 is formed between the two parallel fixed door panels 101. The sliding groove 102 vertically penetrates the door frame 1, and a door opening 103 is opened on the fixed door panel 101. A sliding door 2 is installed in the sliding groove 102, and the sliding door 2 closes or opens the door opening 103 after sliding along the sliding groove 102. A sliding support device 3 is installed on the top of the door frame 1, and the sliding door 2 is lifted and clamped by the sliding support device 3. When the slide plate 2 slides to the desired position, the sliding support device 3 releases the sliding door 2, and the sliding door 2 falls at this time. A driving device 4 is also provided on the top of the door frame 1, and the driving device 4 drives the sliding support device 3 to slide laterally along the door frame 1.

[0037] In the above technical solution, the sliding door 2 is made of high-strength steel door, and the weight of the sliding door 2 is greater than 500 kilograms. After the sliding door 2 is closed, the sliding support device 3 is separated from the sliding door 2. At this time, the bottom of the sliding door 2 is in contact with the bottom of the sliding groove 102, and the sliding door 2 cannot be opened by manpower, which plays an anti-theft role.

[0038] When the sliding door 2 needs to be opened, the sliding support device 3 is adapted to the sliding door 2 by remote control. At this time, the sliding door 2 is lifted, and the sliding support device 3 is driven to move by the driving device 4, which drives the sliding door 2 to move to complete the opening or closing.

[0039] See Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, two bracket plates 5 are symmetrically arranged at the front and rear above the door frame 1, and a gap corresponding to the sliding groove 102 is formed between the two bracket plates 5. The upper end of the sliding door 2 is processed to form a flat plate portion 21, and the flat plate portion 21 is limited between the bracket plates 5 on both sides and is supported by the bracket plates 5 through the sliding support device 3. The front and rear sides of the flat plate portion 21 are provided with force grooves 22 that cooperate with the sliding support device 3.

[0040] In the above technical solution, the flat plate portion 21 is used to limit the downward movement of the sliding door 2. Friction is generated by the contact between the flat plate portion 21 and the bracket plate 5. When the sliding door 2 is not lifted, the sliding friction of the sliding door 2 is increased, further preventing the sliding door 2 from being maliciously slid open.

[0041] See Figure 5 and Figure 7As shown, the sliding support device 3 includes a frame 31, and pulley grooves are provided on both sides of the bottom of the frame 31. A plurality of pulleys 32 are installed in each of the pulley grooves, and a plurality of hydraulic jacks 33 are fixed at the front and rear end surfaces of the frame 31. The output end of the hydraulic jack 33 is detachably installed with a force block 34, and the upper end of the force block 34 is processed to form a force inclined surface 35 for jacking. The force block 34 is inserted into the force groove 22, and the force inclined surface 35 acts on the force groove 22. When the hydraulic jack 33 is extended, the force inclined surface 35 cooperates with the force groove 22 to lift the sliding door 2, and the bottom of the sliding door 2 is off the ground; an oil cylinder 36 and an oil pump 37 for supplying oil to the hydraulic jack 33 are installed at the upper end of the frame 31, and a connecting pipe 38 is installed at the oblique angle of the frame 31, and the driving device 4 is cooperated through the connecting pipe 38.

[0042] In the above technical solution, the hydraulic jack 33 is pushed out to insert the force block 34 into the force groove 22. At this time, the sliding door 2 is moved upward and supported by the pulley 32 so that the sliding door 2 can slide easily.

[0043] The sliding door 2 can be easily lifted up and lowered by means of a plurality of hydraulic jacks 33 .

[0044] See Figure 6 As shown, a wheel groove 501 is provided on the top of the bracket plate 5 to match the pulley 32. Both ends of the wheel groove 501 are closed, and a guide groove 502 for draining the lubricating fluid is processed on the side of the wheel groove 501. The guide groove 502 passes through the direction of the sliding door 2. The lubricating fluid in the wheel groove 501 acts on the sliding door 2 after passing through the guide groove 502, so that the resistance of the sliding door 2 when sliding along the bracket plates 5 on both sides is reduced.

[0045] In the above technical solution, the depth of the wheel groove 501 is slightly deeper than the depth of the guide groove 502, so that some lubricating oil will remain in the wheel groove 501 to reduce the moving friction of the pulley 32, and the excess lubricating oil will flow along the guide groove 502 into between the bracket plate 5 and the sliding door 2, thereby reducing the moving resistance of the sliding door 2.

[0046] See Figure 6 As shown, a groove 503 is provided at the end face of the bracket plate 5 that acts on the sliding door 2, and a rubber strip 504 is embedded at the bottom of the groove 503. A recovery hole 505 is passed through the side of the bracket plate 5. The excess lubricating fluid flows down along the bracket plate 5 and is intercepted by the rubber strip 504 and discharged through the recovery hole 505. A groove plate 506 is provided on the inner side of the bracket plate 5, and the lubricating fluid discharged through the recovery hole 505 flows into the groove plate 506.

[0047] In the above technical solution, excess lubricating liquid can be collected to avoid a lot of oil residue on the surface of the sliding door.

[0048] When in use, the rubber strip 504 on the end surface of the sliding door 2 facing outward can be removed, so that the lubricating liquid flows down along the outer surface of the sliding door 2, making the surface of the sliding door 2 facing the outside smoother and without any place to put pressure, thereby preventing the sliding door 2 from being pushed open.

[0049] See Figure 2 and Figure 7 As shown, the driving device 4 includes two wheel axles 41, and a bearing seat 42 is provided between the wheel axles 41 and the door frame 1. Two wheel discs 43 are provided on the outside of each wheel axle 41, and a wheel groove is provided on the outside of the wheel disc 43. A traction rope 44 is provided between the wheel axles 41 on both sides through the wheel disc 43. The traction rope 44 passes through the connecting pipe 38, and the connecting pipe 38 is fixed to the traction rope 44. A frame plate 121 is installed on the side of the door frame 1 facing the interior, and a reducer 45 is installed on the frame plate 121. A motor 46 is installed at the input end of the reducer 45, and the output end of the reducer 45 is connected to the wheel axle 41 on one side.

[0050] In the above technical solution, the rotation of the wheel 43 drives the movement of the traction rope 44, and the traction rope 44 is used to pull the sliding support device 3 to slide.

[0051] In addition to the above-mentioned technology, a tensioning mechanism may be installed on the upper portion of the door frame to tension the traction rope 44 in response to tensioning needs.

[0052] See Figure 4 and Figure 5 As shown, a hollow counterweight cavity 2221 is provided inside the sliding door 2 , and a liquid injection hole 2222 communicating with the counterweight cavity 2221 is provided on the top of the flat plate portion 21 .

[0053] In the above technical solution, oil can be injected through the injection hole 2222 to increase the deadweight of the sliding door 2 by injecting oil.

[0054] 5 , an L-shaped auxiliary support plate 3331 is installed between the working block 34 and the output end of the hydraulic jack 33 . The bottom of the auxiliary support plate 3331 is smooth and acts on the top of the bracket plate 5 .

[0055] In the above technical solution, the auxiliary support plate 3331 can help the hydraulic jack to bear the force, thereby increasing the stability of the position of the hydraulic jack when lifting the sliding door 2.

[0056] See Figure 5 and Figure 6As shown, the top of the bracket plate 5 is processed to form a smooth surface 5551 at a position corresponding to the auxiliary support plate 3331 , and the top of the bracket plate 5 is processed to form a rough surface 5552 at a position corresponding to the flat plate portion 21 .

[0057] The design of the smooth surface 5551 reduces the resistance of the auxiliary support plate 3331 when it slides along the bracket plate 5. Especially after the sliding door 2 is lifted, the downward pressure of the auxiliary support plate 3331 increases. At this time, the design of the smooth surface 5551 can greatly reduce the friction, allowing the driving device 4 to more easily drive the sliding door to move.

[0058] See Figure 1 As shown, the length of the door opening 103 from one side door frame 1 is L, and the length from the other side door frame 1 is L1, L is greater than the width of the sliding door 2, L1 is less than the width of the sliding door 2, and the width of the sliding door 2 is greater than the width of the door opening 103.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
