Description

Technical Field

[0001] The invention relates to the technical field of sliding doors, in particular to a multi-point lock linked lifting and sliding door. Background Art

[0002] The traditional lifting and sliding door uses the principle of lever mechanics. By turning the special long-arm handle, the lifting and lowering of the door leaf is controlled to achieve the fixing and opening of the door leaf. The operation method is: when the handle is turned downward, the pulley falls on the track of the lower frame through the connected transmission device, and drives the door leaf upward. At this time, the door leaf is in an open state and can be pushed, pulled and slid freely; when the handle is turned upward, the pulley is separated from the lower frame track and the door leaf descends. The door leaf is pressed against the door frame by gravity, and the door leaf is in a closed state. The disadvantage is that only the lock on the same side can be opened, and the transmission device and locking system on the adjacent side cannot be opened. This is the biggest disadvantage and difficulty of the conventional series. The biggest problem caused by this defect is the width and use of the profile at the corner position. Because the locking function of the corner is required, the profile at the corner position has a very wide section in order to install hardware. In order to achieve the effect of no column, some profiles are even elongated, which seriously affects the appearance and use experience.

[0003] The cross-section of the profile at the butt joint of the traditional lifting and sliding door frame is too wide, because it requires the linkage of hardware, the installation space of hardware, and the space required for the butt joint of the profile. The glass of any leaf needs to be slotted. The width of the door leaf seriously affects the lighting and visual beauty. In addition, the method of realizing the positive angle at the corner of the conventional lifting and sliding door is common, but when making the negative angle, it is often impossible to achieve or the corner is not locked due to the conflict between the handle and the hardware.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The principle of the multi-point lock linkage lifting and sliding door is still the principle of lever mechanics. When the handle is turned, the transmission rods on the same side and in the symmetrical position can be driven to realize the opening and closing of the four sides of the door leaf. It is especially suitable for lifting and sliding door systems with extra-large and extra-wide sizes.

[0017] 2. The present invention has an autonomous lubrication mechanism. When the roller is not lubricated enough during rotation, the air nozzle moves to allow outside air to replenish the oil tank, and then the lubricant in the oil tank is squeezed out through the fine folded tube. The lubricant drips and smears on the roller shaft, so that the rotation of the roller is fully lubricated. In this way, the resistance encountered when pushing and pulling the first moving door frame will be minimized. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The bottom wheel 13 includes a main frame 26, a T-block 27, a pressure plate 28, a pile block 29, a pulling plate 30 and a half-wheel portion 31.

The pressure column 34 is distributed between the two guide blocks 32, and the pressure column 34 passes through the inclined plate hole opened on the T block 27. The pulling plate 30 slides through the long groove opened on the outer wall of the ear plate 33, and the pile block 29 slides through the column hole opened on the guide block 32 by setting a cylinder.

[0047] The half-wheel portion 31 includes a baffle plate 36, an air nozzle 38, a roller 39, a roller shaft 40, a concave folding plate 41, a thin folding tube 42 and an oil tank 43.

One end of the oil tank 43 is fixed on the concave folding plate 41, and a roller shaft 40 passes through the middle of the roller 39. The roller shaft 40 is movably sleeved in a through hole opened on the concave folding plate 41. One end of the thin folding tube 42 is fixedly connected to the oil tank 43, and the other end is distributed in a notch opened on the concave folding plate 41. The lubricant discharged from the thin folding tube 42 drips on the side wall of the roller shaft 40. One end of the air nozzle 38 is connected to the oil tank 43, and the other end contacts the T-plate fixed on the baffle plate 36.

[0050] The present invention can drive the transmission rods on the same side and symmetrically to open and close the four sides of the door leaf by rotating the handle, and can be used for lifting and sliding door systems of extra-large and extra-wide sizes. The rotation of the handle will cause the bottom wheel 13 to deform, for example, Fig.15 and Fig.17 When the second secondary shaft 14 rotates, the spiral column of the second secondary shaft 14 pushes the pressure plate 28 horizontally, thereby driving the T block 27 to move horizontally. The inclined plate hole on the T block 27 pushes down the pressure column 34, thereby controlling the entire main frame 26 to descend. The main frame 26 drives the half wheel part 31 to descend as a whole, so that the roller 39 on the half wheel part 31 descends. After the roller 39 contacts the ground track, the reaction support makes the first movable door frame 1 rise as a whole. After the ascent is completed, the first movable door frame 1 can be pushed horizontally by the switch. The half wheel part 31 has an autonomous lubrication mechanism. The first movable door frame 1 plus the glass supported by the first movable door frame 1 will have pressure acting on the roller 39. Under such pressure, the roller 39 rolls, and the pressure is mainly concentrated on the contact surface between the roller shaft 40 and the concave folding car plate 41, that is, on the outer wall of the roller shaft 40. If the contact lubrication between the concave folding car plate 41 and the roller shaft 40 is insufficient, on the one hand, friction noise will be generated during the process of pushing the first movable door frame 1 horizontally, and on the other hand, it will be difficult to push the first movable door frame 1. Therefore, an automatic lubrication mechanism is required. Once the roller shaft 40 has difficulty in rotating, people continue to push the first movable door frame 1 horizontally. The difficulty in rotating the roller 39 will cause the half-wheel part 31 to remain relatively motionless, and the first movable door frame 1 will drive other structures on the bottom wheel 13 to translate synchronously, so that the half-wheel part 31 moves relative to the main frame 26, that is Fig.17 The main frame 26 in the figure can be regarded as stationary, the half wheel parts 31 at both ends move synchronously, the baffle 36 and the main frame 26 are fixed, and the air nozzle 38 moves with the roller 39, so that the air nozzle 38 moves relative to the baffle 36. Fig.18 and Fig.19 The movement of the air nozzle 38 will cause the piston column 46 to continuously expand and contract in the T-shaped flat tube 45, and then the air flow in the T-shaped flat tube 45 will flow unidirectionally, the outside air will be sucked into the T-shaped flat tube 45, and then injected into the oil tank 43, the air pressure in the oil tank 43 will rise, and then the lubricant stored in the oil tank 43 will be squeezed out, and the lubricant will drip and smear on the roller shaft 40, and when the roller shaft 40 rotates, the lubricant will spread between the concave folding car plate 41 and the roller shaft 40.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
