Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a lifting and ejection mechanism. Background Technology

[0002] When installing doors and windows, there may be a large gap between the door / window frame and the installation location. If conventional sealing strips are used to fill the gap, the strips may not be able to meet the needs of such a large gap and thus cannot completely fill it. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting and ejection mechanism to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a lifting and ejecting mechanism for filling gaps in doors and windows. The lifting and ejecting mechanism includes: a support base with a groove, the middle of which is bent so that the extension directions of the two ends of the groove are perpendicular to each other; a transmission plate slidably disposed in the groove, with both ends of the transmission plate extending out of the support base from the two ends of the groove; and a sliding assembly installed on one end of the transmission plate extending out of the top of the support base and slidably connected to the support base. A drive slider is installed on the other end of the transmission plate. The support base is installed on one side of the gap in the door and window. By moving the drive slider, the sliding assembly can be moved to the other side of the gap in the door and window, thereby filling the gap in the door and window.

[0005] This technical solution has at least the following beneficial effects: by horizontally pulling the drive slider, the sliding kit moves longitudinally under the drive of the transmission plate, and lifts and pushes out the door and window frame, thereby filling the gap between the door and window frame and the installation position, which is suitable for door and window gaps that cannot be filled by the rubber strip.

[0006] As a further improvement to the above technical solution, the support base includes a base and a fastener connected to each other. The slide groove is divided into a first straight section, a curved section, and a second straight section connected in sequence. The first straight section is disposed on the base, and the curved section and the second straight section are formed between the fastener and the base. One end of the transmission plate can be passed through the first straight section first. When the fastener is installed on the base, the other end of the transmission plate is clamped between the fastener and the base, thereby facilitating the installation of the transmission plate.

[0007] As a further improvement to the above technical solution, the base is provided with a first slot, and the fastener is provided with a first locking block that can be locked in the slot. This facilitates the installation and disassembly of the fastener and the base.

[0008] As a further improvement to the above technical solution, a second locking block is provided at one end of the bent section of the fastener, and a second locking groove is provided on the base for the second locking block to engage. This improves the connection stability between the fastener and the base and ensures the transmission stability of the transmission plate.

[0009] As a further improvement to the above technical solution, the top of the support base is provided with an inner groove that communicates with the slide groove. The inner groove extends through the support base along a direction perpendicular to the extension of the slide groove. The width of the inner groove is smaller than the width of the slide groove, and the connection position between the transmission plate and the sliding assembly can extend into the inner groove. This makes the overall structure more compact and stable.

[0010] As a further improvement to the above technical solution, the sliding assembly has a through hole in the middle for the top of the support to slide through, and the sliding assembly has a clearance notch connecting the through hole. This can improve the stability of the sliding assembly relative to the support, and the clearance notch facilitates the assembly and connection of the transmission plate and the sliding assembly.

[0011] As a further improvement to the above technical solution, a compression plate is slidably mounted on the top of the sliding kit, and an elastic element is installed between the compression plate and the sliding kit. The elastic element provides elastic force along the sliding direction of the sliding kit, causing the compression plate to move away from the sliding kit. The compression plate, instead of the sliding kit, abuts against or connects to the door and window profiles, which can reduce the jamming phenomenon caused by external factors when pushing against the door and window frames.

[0012] As a further improvement to the above technical solution, the compression plate is provided with a connecting post, and the top of the sliding kit has a connecting hole for the connecting post to slide into. The elastic element is a helical spring with its two ends connected between the connecting post and the bottom wall of the connecting hole, respectively. This improves the stability of the relative sliding between the compression plate and the sliding kit, and makes the overall structure more compact and stable.

[0013] As a further improvement to the above technical solution, the sliding assembly has a limiting hole perpendicular to the connecting hole, the limiting hole communicating with the connecting hole, and a limiting post slidably disposed within the limiting hole, through which the connecting post passes. The limiting post slides within the limiting hole, restricting the extension and retraction range of the compression plate, thereby ensuring the stability of the compression plate's sliding relative to the sliding assembly.

[0014] As a further improvement to the above technical solution, it also includes a first profile and a second profile with a gap between them. The support base is installed on the first profile, and the first profile is provided with a slide rail for the drive slider to slide. The bottom of the support base has a through slot for the slide rail to pass through. The drive slider is provided with a protrusion that slides relative to the support base. The sliding of the drive slider can drive the sliding assembly to push out of the second profile to fill the gap between the door and window. The first profile restricts the drive slider, which can improve the sliding stability of the drive slider, thereby ensuring that the sliding assembly can be smoothly pushed up.

[0029] Reference Figure 1-8 The lifting and ejection mechanism includes a support base, a transmission plate 400, and a sliding assembly 500.

[0030] The support includes a base 100 and a fastener 200. The base 100 is provided with four first slots 110, which penetrate the top surface of the base 100 and have an L-shaped cross-section, forming a snap-fit ​​platform on one side of the first slot 110. The top of the fastener 200 is equipped with four first blocks 210, which correspond to the four first slots 110 respectively. The first blocks 210 have an L-shaped hook structure, so that after the first blocks 210 extend into the first slots 110, they can be snapped onto the snap-fit ​​platform of the first slots 110, thereby realizing the assembly connection between the fastener 200 and the base 100.

[0031] The support base is provided with a sliding groove 300, which is curved in the middle, dividing the groove 300 into a first straight section 310, a curved section 320, and a second straight section 330. The extension directions of the first straight section 310 and the second straight section 330 are perpendicular to each other. The first straight section 310 is vertically positioned at the top of the base 100. One side of the fastener 200 has a curved arc plate, forming the curved section 320 between the arc plate and the base 100. The other side of the fastener 200 forms the second straight section 330 between itself and the base 100. A second locking block 220 is provided at the end of the arc plate away from the second straight section 330, after bending downwards. The width of the second locking block 220 is smaller than the width of the arc plate. A second slot 120 is provided on the inner side of the base 100, and the second slot 120 also forms a locking platform. When the fastener 200 is locked onto the base 100 by the first locking block 210, the second locking block 220 is also locked onto the locking platform of the second slot 120, thereby further stabilizing the position of the arc plate and improving the installation stability of the fastener 200 relative to the base 100. In addition, a mutual interlocking convex-concave structure can be provided between the fastener 200 and the base 100 to ensure the relative installation accuracy between the fastener 200 and the base 100.

[0032] The transmission plate 400 is a flexible steel sheet. It is slidably mounted in the groove 300, with both ends extending from the first straight section 310 and the second straight section 330, respectively, so that the two ends are perpendicular to each other. During installation, one end of the transmission plate 400 can be passed through the first straight section 310 of the base 100, and then the fastener 200 can be fastened onto the base 100. This creates a barrier between the fastener 200 and the base 100, restricting the bending section 320 and the second straight section 330 at the other end of the transmission plate 400, allowing for quick and convenient installation of the transmission plate 400.

[0033] The base 100 has an inner groove 130 on its top. The inner groove 130 extends through the front and rear sides of the base 100, and the through position of the inner groove 130 corresponds to the first straight section 310 of the slide groove 300. The through direction of the inner groove 130 is perpendicular to the extension direction of the first straight section 310, so that the inner groove 130 is connected to the first straight section 310 of the slide groove 300. However, the width of the inner groove 130 is smaller than the width of the slide groove 300, so as to ensure that the slide groove 300 restricts the two sides of the transmission plate 400.

[0034] The sliding kit 500 has a longitudinally arranged through hole 510 in the middle, which is adapted to the top of the base 100, so that the sliding kit 500 can be slidably fitted onto the top of the base 100 in a vertical direction. The sliding kit 500 has a clearance notch 520 on the front side, which is connected to the through hole 510.

[0035] A first screw 410 is installed between the end of the transmission plate 400 that protrudes from the top of the base 100 and the sliding assembly 500. The first screw 410 passes through the clearance notch 520 on the transmission plate 400 and is screwed into the side wall of the through hole 510 of the sliding assembly 500, so that the connection position between the transmission plate 400 and the sliding assembly 500 is in the inner position of the top of the base 100, making full use of the internal space of the base 100, making the outer periphery of the sliding assembly 500 simpler, and making the relative sliding between the sliding assembly 500 and the top of the base 100 more stable and reliable.

[0036] A drive slider 600 is installed at the end of the transmission plate 400 away from the sliding assembly 500, after it protrudes from the bottom side of the base 100. A second screw 420 is installed between the drive slider 600 and the transmission plate 400. The second screw 420 passes through the end of the transmission plate 400 and is screwed into the drive slider 600, thereby securing the transmission plate 400 and the drive slider 600 together. The transmission plate 400 is composed of two stacked steel plates. In other embodiments, the transmission plate 400 may also be made of only one steel plate or composed of multiple stacked steel plates.

[0037] The lifting and ejecting mechanism of this embodiment is used to fill the gap between doors and windows. The base 100 has mounting edges on both sides, and mounting holes are opened on the mounting edges. The base 100 is fixed to one side of the gap between doors and windows by bolts passing through the mounting holes. By moving the drive slider 600, the transmission plate 400 can be pushed to slide in the slide groove 300, thereby pushing the sliding kit 500 to lift relative to the base 100 so as to abut or connect to the other side of the gap between doors and windows, thereby filling the gap between doors and windows.

[0038] In other embodiments, the fastener 200 can also be mounted on the base 100 by screws. The transmission plate 400 and the drive slider 600, as well as the transmission plate 400 and the sliding kit 500, can also be connected by riveting.

[0039] Furthermore, the sliding assembly 500 is equipped with a compression plate 700. Two parallel connecting posts 720 are vertically mounted on the bottom of the compression plate 700. The top of the sliding assembly 500 has two parallel connecting holes 730. The positions of the two connecting holes 730 correspond to the positions of the two connecting posts 720, and the two connecting posts 720 are respectively inserted into the two connecting holes 730, thereby making the compression plate 700 and the sliding assembly 500 slidably connected.

[0040] An elastic element 710 is also provided between the compression plate 700 and the sliding assembly 500. The elastic element 710 provides vertical elastic force to move the compression plate 700 away from the sliding assembly 500. Specifically, the elastic element 710 is a helical spring, and two helical springs are provided. One end of the helical spring is sleeved on the end of the corresponding connecting post 720, and the other end abuts against the bottom of the connecting hole 730, so that the helical spring supports the compression plate 700, creating a certain compression space between the compression plate 700 and the sliding assembly 500.

[0041] When the drive slider 600 is pulled, causing the sliding assembly 500 to move towards the other side of the door and window gap, the compression plate 700 takes over the contact with the other side of the door and window gap. Due to the elastic force of the coil spring, the sliding assembly 500 can still move when the compression plate 700 is in contact with the other side of the door and window gap. The sliding assembly 500 and the compression plate 700 can move flexibly relative to each other, thereby reducing the jamming phenomenon caused by external factors and ensuring that the door and window gap can be filled smoothly.

[0042] In other embodiments, the elastic element 710 can also be configured as an elastic sheet, with one end of the elastic sheet installed at the bottom of the compression plate 700 and the other end abutting against the top of the sliding kit 500. Thus, the elastic force of the elastic sheet can be used to move the compression plate 700 away from the sliding kit 500 by a certain distance. After the compression plate 700 is subjected to pressure, it can overcome the elastic force of the elastic sheet and approach and abut against the sliding kit 500.

[0043] Furthermore, limiting holes 740 are provided on both sides of the sliding assembly 500. The axis of the limiting hole 740 is perpendicular to the axis of the connecting hole 730, and both ends of the limiting hole 740 pass through both sides of the sliding assembly 500. In addition, limiting posts 750 are inserted into the limiting holes 740. The limiting posts 750 can slide vertically within the limiting holes 740, and their sliding range is limited by the two ends of the limiting holes 740. The two limiting holes 740 are respectively located at the positions of the two connecting holes 730, that is, the limiting holes 740 and the corresponding connecting holes 730 are connected, so that the limiting posts 750 can be respectively inserted into the corresponding connecting posts 720, thereby restricting the sliding of the compression plate 700 relative to the sliding assembly 500 within a preset range, thus ensuring the sliding stability and reliability of the compression plate 700 relative to the sliding assembly 500. The limiting post 750 has a head with a large diameter at one end and an annular groove at the other end. After the limiting post 750 passes through the limiting hole 740, a retaining ring with a large diameter is engaged in the annular groove. This allows the head of the limiting post 750 and the retaining ring to clamp the sliding assembly 500, thereby preventing the limiting post 750 from disengaging from the limiting hole 740. At the same time, it also facilitates the installation and removal of the limiting post 750.

[0044] In another embodiment, the lifting and ejecting mechanism further includes a first profile and a second profile, forming a door / window gap between them. A base 100 is bolted to the first profile. A through slot 140 is provided at the bottom of the base 100, extending through both sides of the base 100 along the sliding direction of the drive slider 600. A slide rail is provided inside the first profile, passing through the through slot 140; the through slot 140 can also be understood as a way to avoid the slide rail. The drive slider 600 is slidably disposed within the slide rail, thereby improving the sliding stability of the drive slider 600. A compression plate 700 abuts against or is connected to the second profile via screws. When the drive slider 600 is pushed, the compression plate 700 can be lifted and ejected from the second profile via the transmission plate 400 to fill the door / window gap between the first and second profiles.

[0045] Furthermore, a protrusion 610 is provided on the top of the drive slider 600 for the second screw 420 to screw into. The width of the protrusion 610 is smaller than the width of the transmission plate 400. The fastener 200 has a first limiting groove 620 for the protrusion 610 to slide. Since the second screw 420 protrudes from the protrusion 610, a second limiting groove 630 is provided on the base 100 for the head of the second screw 420 to slide. This improves the stability of the relative sliding between the drive slider 600 and the base 100. In other embodiments, the second screw 420 can also be a countersunk screw, so that the second screw 420 does not protrude from the top surface of the protrusion 610, thus eliminating the need for the second limiting groove 630.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
