Description

Technical Field

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

[0002] Lift-up sliding doors or windows are a common type of product in the construction industry. Their bottom features a sliding lifting mechanism that allows the door or window to be raised or lowered relative to the frame. When raised, the mechanism descends to contact the bottom frame, allowing the door or window to open or close. When lowered, the mechanism retracts upwards, detaching from the bottom frame and securing the door or window. The raising and lowering of the sliding mechanism is controlled by a lock on the door or window. The user turns the handle, which in turn moves the mechanism to open or close the door or window.

[0003] Currently, sliding lifting mechanisms generally include a base, a lifting component, and a sliding component. When the lifting component is lifted longitudinally, it will move relative to the base. However, during the relative movement, a certain friction force will be generated between the lifting component and the base, which will result in greater resistance when the lifting component is lifted longitudinally, as well as greater noise and wear. This leads to a poor service life of the sliding lifting mechanism and affects the convenience and comfort of using the door or window. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting transmission mechanism and a lifting sliding door / window that reduces friction and resistance and increases service life.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions:

[0006] A lifting transmission mechanism, comprising:

[0007] A fixed bracket, wherein the fixed bracket is connected to the bottom of the door or window;

[0008] A linkage component, the middle part of which is rotatably connected to a fixed support;

[0009] A lifting unit is located on the side of a fixed support and can move relative to the fixed support. The lifting unit is rotatably connected to one end of a linkage component and has a roller that rolls in cooperation with the fixed support.

[0010] A sliding unit is provided at the bottom of the fixed support and is rotatably connected to the other end of the linkage component;

[0011] When the lifting unit moves longitudinally, the sliding unit can be driven to move laterally through the linkage component. When the sliding unit moves laterally, it will cause the fixed bracket to move the door and window downwards or upwards.

[0012] In one embodiment, the lifting unit includes a lifting sliding plate and a lifting transmission rod. One end of the lifting transmission rod is connected to the lifting sliding plate, and the other end is rotatably connected to one end of the linkage component. A roller is disposed on the lifting transmission rod.

[0013] In one embodiment, the lifting sliding plate is provided with a slot, and the lifting transmission rod is provided with a locking block. By locking the locking block into the slot, the lifting transmission rod can be connected to the lifting sliding plate.

[0014] In one embodiment, the sliding unit includes a sliding bracket, a pulley, and a connecting rod. One end of the connecting rod is rotatably connected to the linkage component, and the other end is connected to the sliding bracket. The pulley is rotatably mounted on the sliding bracket.

[0015] In one embodiment, the fixed support has a fixing part and a first guide hole is provided in the fixing part. The first guide hole is inclined. A first roller is provided on the sliding bracket and the first roller is placed in the first guide hole.

[0016] In one embodiment, the lifting transmission mechanism further includes a secondary sliding unit, which is connected to the sliding unit via a tie rod.

[0017] In one embodiment, the secondary sliding unit includes a secondary sliding bracket, a secondary pulley, and a fixing block. The secondary pulley is rotatably mounted on the secondary sliding bracket. A second guide hole is provided on the fixing block, and a second roller is provided on the secondary sliding bracket, with the second roller placed in the second guide hole.

The lifting sliding plate is connected to the lock body, and the lifting sliding plate can be driven to move longitudinally when the lock body is locked or unlocked.

[0020] In addition, this utility model also provides a lifting and sliding door / window, including any of the above-mentioned lifting transmission mechanisms. Beneficial effects

[0021] This utility model relates to a lifting transmission mechanism and a lifting sliding door / window. The lifting unit is located on the side of a fixed support, and a roller is installed on the lifting transmission rod of the lifting unit. When the lifting unit moves longitudinally, the side of the fixed support moves relative to the lifting unit. During this movement, the roller on the lifting transmission rod effectively reduces the friction between the side of the fixed support and the lifting transmission rod, thereby reducing the resistance of the lifting unit in the longitudinal direction. It also reduces the noise and wear generated when the lifting unit moves relative to the fixed support, thus improving the overall service life and ensuring the convenience and comfort of using the door or window.

[0041] Please see Figures 1 to 8 A lifting transmission mechanism, comprising:

[0042] A fixed support 100 is connected to the bottom of the door or window;

[0043] A linkage component 200, the middle part of which is rotatably connected to the fixed support 100;

[0044] A lifting unit 300 is located on the side of the fixed support 100 and can move relative to the fixed support 100. The lifting unit 300 is rotatably connected to one end of the linkage component 200. The lifting unit 300 has a roller 330 that rolls in cooperation with the fixed support 100.

[0045] A sliding unit 400 is provided at the bottom of the fixed support 100 and is rotatably connected to the other end of the linkage component 200.

[0046] Specifically, in this embodiment, the lifting unit 300 is disposed on the side of the fixed support 100, while the sliding unit 400 is disposed at the bottom of the fixed support 100. The lifting unit 300 and the sliding unit 400 are connected by a linkage component 200. The fixed support 100 can be connected to the bottom of the door leaf or door / window. A roller 330 is provided on the lifting unit 300. When the user drives the lifting unit 300 to move longitudinally, the lifting unit 300 will move the sliding unit 400 laterally through the linkage component 200. When the sliding unit 400 moves laterally, it will cause the fixed support 100 to move the door / window or door leaf downwards to fit tightly with the frame on the ground, or move upwards to separate from the frame on the ground, thereby realizing the unlocking and unlocking of the door / window or door leaf.

[0047] When the lifting unit 300 moves longitudinally, the side of the fixed support 100 moves relative to the lifting unit 300. During this movement, the roller 330 of the lifting unit 300 effectively reduces the friction between the side of the fixed support 100 and the lifting unit 300, thereby reducing the resistance of the lifting unit 300 in the longitudinal direction. It also reduces the noise and wear generated when the lifting unit 300 moves relative to the fixed support 100, thus improving the overall service life and ensuring the convenience and comfort of using the door leaf or window.

[0048] Meanwhile, in this embodiment, the linkage component 200 is integrally precision cast. By designing the existing split linkage component into an integral structure and performing precision casting, the overall structural strength of the linkage component 200 can be improved, thereby improving the durability of the linkage component 200 and thus increasing the service life of the transmission mechanism.

[0049] In addition, in order to enable the lifting unit 300 and the sliding unit 400 to work normally, the lifting transmission mechanism in this embodiment also includes a mounting frame 700. The mounting frame 700 can be installed on the door or window or door leaf, and the mounting frame 700 has a lock body mounting position 710. The lock body mounting position 710 is used to install the lock body (not shown in the figure). The lifting unit 300 is connected to the lock body. When the lock body is locked or unlocked, it will drive the lifting unit 300 to move longitudinally. When the lifting unit 300 moves longitudinally, it will carry the sliding unit 400 to move laterally through the linkage component 200, so that the fixed support 100 moves the door or window or door leaf downward to fit tightly with the frame on the ground, or moves upward to separate from the frame on the ground.

[0050] Please see Figure 3 In this embodiment, the lifting unit 300 includes a lifting sliding plate 310 and a lifting transmission rod 320. One end of the lifting sliding plate 310 is connected to the lifting transmission rod 320, and the other end is connected to the lock body. The other end of the lifting transmission rod 320 is rotatably connected to the linkage member 200. The roller 330 is disposed on the lifting transmission rod 320. When the lock body rotates, it drives the lifting sliding plate 310 to move longitudinally. When the lifting sliding plate 310 moves, it carries the lifting transmission rod 320 to move. The lifting transmission rod 320 then drives the sliding unit 400 to move laterally through the linkage member 200, thereby realizing the linkage between the lifting unit 300 and the sliding unit 400.

[0051] In order to ensure the connection between the lifting sliding plate 310 and the lifting transmission rod 320, a slot 311 is provided in the lifting sliding plate 310 and a locking block 321 is provided in the lifting transmission rod 320. When connecting, the locking block 321 is inserted into the slot 311 to achieve the connection between the lifting transmission rod 320 and the lifting sliding plate 310.

[0052] Please see Figure 5 and Figure 6 In order to realize the lateral movement of the sliding unit 400 and drive the fixed support 100 to rise and fall, the sliding unit 400 in this embodiment includes a sliding bracket 410, a pulley 420 and a connecting rod 430. One end of the connecting rod 430 is rotatably connected to the linkage member 200, and the other end is connected to the sliding bracket 410. The pulley 420 is rotatably mounted on the sliding bracket 410. The fixed support 100 has a fixing part 110 and a first guide hole 111 is provided in the fixing part 110. The first guide hole 111 is inclined. A first roller 411 is provided on the sliding bracket 410 and the first roller 411 is placed in the first guide hole 111.

[0053] One end of the connecting rod 430 is rotatably connected to the linkage component 200, and the other end is rotatably connected to the sliding bracket 410. The pulley 420 is mounted on the sliding bracket 410. When the lifting unit 300 moves longitudinally, it will move the connecting rod 430 through the linkage component 200. When the connecting rod 430 moves, it will drive the pulley 420 to move the sliding bracket 410 laterally. When the sliding bracket 410 moves laterally, it will move the first roller 411 in the first guide hole 111 of the fixed part 110. Since the first guide hole 111 is inclined, when the first roller 411 moves in the first guide hole 111, it will drive the fixed support 100 to rise and fall, thereby moving the door leaf or window up and down, tightly fitting with the frame on the ground or separating from the frame on the ground.

[0054] Please see Figure 7 In order to improve the overall load-bearing capacity of the mechanism, the lifting transmission mechanism in this embodiment also includes a secondary sliding unit 500. The secondary sliding unit 500 is connected to the sliding unit 400 through a tie rod 600. The secondary sliding unit 500 includes a secondary sliding bracket 510, a secondary pulley 520 and a fixing block 530. The secondary pulley 520 is rotatably mounted on the secondary sliding bracket 510. A second guide hole 531 is provided on the fixing block 530, and a second roller 511 is provided on the secondary sliding bracket 510 and placed in the second guide hole 531.

[0055] Since the door leaf or window needs to be supported by the fixed bracket 100, the performance of the fixed bracket 100 can be further improved by adding the auxiliary sliding unit 500. At the same time, the auxiliary pulley 520 is set on the auxiliary sliding bracket 510 to facilitate the lateral movement of the auxiliary sliding unit 500, thereby moving the door leaf or window. The second guide hole 531 on the fixed block 530 and the second roller 511 on the auxiliary sliding bracket 510 correspond to the first guide hole 111 and the first roller 411 to realize the lifting and lowering of the fixed bracket 100, thereby realizing the vertical movement of the door leaf or window.

[0056] Finally, this utility model also provides a lifting and sliding door / window, including any of the above-mentioned lifting transmission mechanisms. When the lifting unit 300 moves longitudinally, the side of the fixed support 100 moves relative to the lifting unit 300. During the movement, the roller 300 of the lifting unit 300 can effectively reduce the friction between the side of the fixed support 100 and the lifting unit 300, thereby reducing the resistance of the lifting unit 300 in the longitudinal lifting. At the same time, it can also reduce the noise and wear generated when the lifting unit 300 and the fixed support 100 move relative to each other, thereby improving the overall service life and ensuring the convenience and comfort of using the door leaf or door / window.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
