Description

[0002] In the prior art, in order to achieve the buffering effect in the process of lowering the door leaf and the boosting effect in the process of lifting, a metal spring or an air pressure spring is directly connected to improve the hand feeling of the handle during operation. However, with the continuous development of the door and window market and the increasing diversity of customer demand, the size and weight specifications of the lifting sliding door leaf are increasingly diversified, so that the traditional single metal spring cannot meet the buffering and boosting functions of the heavy door leaf, resulting in heavy hand feeling of the handle during operation. Similarly, the force value of the air pressure spring of the lifting transmission device is basically a constant value. When the weight of the door leaf is light, the handle needs to offset the remaining pressure of the air pressure spring, resulting in heavy hand feeling of the handle during operation. When the weight of the door leaf is too heavy, the force value of the air pressure spring is insufficient to offset the force of the self-weight of the door leaf applied to the transmission device, also resulting in heavy hand feeling of the handle during operation.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0048] Example 1

[0049] Reference Figures 1-19 The present embodiment discloses an adjustable buffer booster of a lifting sliding door transmission device, which is applied to a lifting sliding door transmission device. The lifting sliding door transmission device includes a transmission device panel 36, a transmission bar 1, a transmission assembly, etc. The specific embodiments of the lifting sliding door transmission device can be referred to the prior art. The adjustable buffer booster of the present embodiment includes an elastic element 2, a fixed support 14, and an adjusting mechanism for changing the compression amplitude of the elastic element 2. The elastic element 2 of the present embodiment is a spring.

[0050] The elastic element 2 is arranged at one side of the transmission bar 1, one end of the elastic element 2 is arranged in the fixed support 14, the fixed support 14 is fixedly connected with the transmission panel 36, and the adjusting mechanism is arranged at the other end of the elastic element 2. The adjusting mechanism comprises a moving piece 3 and a driving assembly for driving the moving piece 3 to reciprocate along the extension direction of the elastic element 2, the moving piece 3 corresponds to the end of the elastic element 2; the adjusting mechanism further comprises a limiting part for preventing the moving piece 3 from freely moving in the unoperated state.

[0051] In the embodiment, the driving assembly comprises a driving piece 15 and a driven piece 16, the driving piece 15 and the driven piece 16 are intermeshed through the gear 11 and the rack structure; the transmission bar 1 of the lifting sliding door transmission device is provided with a first through hole 5, the transmission panel 36 is provided with a second through hole 37, the operating end of the driving piece 15 corresponds to the first through hole 5 and the second through hole 37; one end of the driven piece 16 corresponds to the moving piece 3. Specifically, when the elastic element 2 is adjusted, a screwdriver or other rotating tool is matched with the operating end of the driving piece 15, because the first through hole 5 is arranged on the transmission bar 1 and the second through hole 37 is arranged on the transmission panel 36, the driving piece 15 is exposed, so that it is more convenient to match, and it can be operated outside the transmission panel 36; then, the rotating tool drives the driving piece 15 to rotate, through the linkage of the gear 11 and the rack structure, the driven piece 16 is driven to move linearly, and the moving piece 3 is synchronously driven to compress the elastic element 2 to overcome the obstruction of the limiting part, so that the elastic force value adjustment of the elastic element 2 is realized; after adjustment, the driving assembly no longer actively drives the moving piece 3 to move, the position of the moving piece 3 is fixed under the action of the limiting part, and the elastic force value of the elastic element 2 at this time is maintained. In the embodiment, the correspondence between one end of the driven piece 16 and the moving piece 3 can be that the end of the driven piece 16 is fixedly connected with the moving piece 3, or the end of the driven piece 16 is in alignment with the moving piece 3, and the connection relationship between the driven piece 16 and the moving piece 3 is not limited in detail, as long as the driven piece 16 can drive the moving piece 3 to move in the compression direction of the elastic element 2.

[0052] The driven piece 16 comprises a transmission part 7 and a butt joint part 8, the transmission part 7 is provided with a rack structure, the butt joint part 8 is arranged at one end of the transmission part 7, and the butt joint part 8 is provided with a mounting groove 33; the end of the moving piece 3 is arranged in the mounting groove 33.

[0053] In order to facilitate the installation of the driving part 15, the driven part 16, the moving part 3 and other components, the adjusting mechanism of the embodiment further comprises a mounting box 4; the mounting box 4 is provided with a mounting groove 19, and the driven part 16 is slidably arranged in the mounting groove 19; the driving part 15 is arranged on the mounting box 4, and the driving part 15 is located on one side of the driven part 16. In addition, the mounting box 4 is provided with two connecting holes 21, and the mounting and fixation with the transmission bar 1 can be achieved through the first screw 39. Further, one end of the mounting box 4 is provided with a connecting step 20, and the temporary fixation with the transmission panel 36 can be achieved through the second screw 40, so as to improve the stability of the lifting sliding door transmission device during delivery.

[0054] Specifically, in order to ensure that the transmission device locking state does not change in the delivery state, and to ensure the position fixation of the transmission bar 1, the mounting box 4, the transmission bar 1 and the transmission panel 36 are fixed at the same time through the second screw 40, and one end of the elastic element 2 is also fixed with the transmission panel 36 through the fixed support 14. Therefore, the adjustable buffer booster of the embodiment cannot act on the transmission bar 1, and the stability of each component in the delivery state is ensured, and the transmission bar 1 cannot reciprocate. When it is necessary to install the lifting sliding door transmission device, the second screw 40 is unscrewed, and the connection of the mounting box 4, the transmission bar 1 and the transmission panel 36 is released. At this time, the transmission bar 1 and the adjustable buffer booster of the embodiment can be normally used.

[0055] The mounting box 4 of the embodiment is provided with a positioning seat 12, which is arranged on the side of the driving part 15 away from the transmission bar 1. The mounting box 4 is provided with a blocking part 17 for limiting the rotation of the positioning seat 12. In the embodiment, the blocking part 17 is two protruding blocking blocks, and the positioning seat 12 is provided with a corresponding recessed groove 30, and the blocking blocks are arranged in the recessed groove 30, so as to realize the rotation limitation of the positioning seat 12. At the same time, the mounting box 4 is also provided with a circular groove 18, and the positioning seat 12 is arranged in a cylindrical shape. The positioning seat 12 is matched and arranged in the circular groove 18, so as to realize the translation limitation of the positioning seat 12; that is, the positioning seat 12 can only move in the axial direction.

[0056] Further, the positioning seat 12 of the embodiment is provided with a rotation positioning assembly for providing rotation angle steps for the driving member 15; the positioning seat 12 is provided with an elastic member 13 between the positioning seat 12 and the mounting box 4, and under the elastic action of the elastic member 13, the positioning seat 12 abuts against the driving member 15; the elastic member 13 in the embodiment is a spring. Specifically, the rotation positioning assembly of the embodiment comprises a plurality of positioning protrusions 24 and a plurality of positioning grooves 29, each of the positioning protrusions 24 corresponds to each of the positioning grooves 29, and each of the positioning protrusions 24 and each of the positioning grooves 29 are distributed at equal angles along the circumferential direction; the front side of each of the positioning protrusions 24 and each of the positioning grooves 29 is obliquely arranged and cooperates with each other along the rotation direction of the positioning protrusion 24, so as to facilitate the positioning protrusion 24 to rotate from one of the positioning grooves 29 to the adjacent positioning groove 29 in front; the rear side of each of the positioning protrusions 24 and each of the positioning grooves 29 constitutes the limiting part, so as to prevent the driving member 15 from rotating reversely to limit the free movement of the moving member 3.

[0057] Further, the positioning protrusion 24 in the embodiment is arranged on the end face of the driving member 15 close to the positioning seat 12, and the positioning groove 29 is arranged on the end face of the positioning seat 12 close to the driving member 15; in addition, the rear side of the positioning protrusion 24 and the rear side of the positioning groove 29 in the embodiment are arranged vertically or reversely obliquely arranged with the front side, so as to ensure that the driving member 15 can only rotate relative to the positioning seat 12 in one direction. Since the positioning seat 12 is limited by the blocking part 17 on the mounting box 4 and cannot rotate, when the driving member 15 rotates, the positioning protrusion 24 slides forward along the inclined surface of the positioning groove 29, and the positioning seat 12 moves to the side away from the driving member 15 against the elastic force of the elastic member 13, so that the driving member 15 rotates one step relative to the positioning seat 12, that is, rotates an angle of one positioning groove 29, so as to drive the driven member 16 and the moving member 3, and complete the compression of the elastic element 2 and realize the adjustment of the elastic force value. After one step rotation is completed, under the elastic force of the elastic member 13, the positioning seat 12 moves to the side close to the driving member 15 again, and repositions and limits the driving member 15 by the cooperation of the positioning groove 29 and the positioning protrusion 24, so that the moving member 3 and the driven member 16 cannot be reversely reset under the condition that the elastic element 2 is compressed, and the position of the driving member 15, the driven member 16, the moving member 3 and the elastic element 2 is limited.

[0058] As another embodiment, the arrangement positions of the positioning protrusion 24 and the positioning groove 29 can be interchanged, and the rotation positioning effect can also be achieved; for example, the positioning protrusion 24 can be arranged on the end face of the positioning seat 12, and the positioning groove 29 can be arranged on the end face of the driving member 15.

[0059] As another embodiment, the front side and the rear side of the positioning protrusion 24 and the positioning groove 29 can also be set as rotatable inclined directions, i.e. the positioning protrusion 24 and the positioning groove 29 are substantially trapezoidal. At this time, the side blocking ability of the positioning protrusion 24 and the positioning groove 29 is utilized to limit the free reset of the moving part 3 and the elastic element 2, and to ensure the adjusted position; while the driving part 15 can be rotated forward or reversely, to realize the compression adjustment or the stretched adjustment of the elastic element 2 after compression.

[0060] As another embodiment, the rotating positioning assembly can also adopt other embodiments, which can be referred to the prior art. For example, the ball and groove cooperation is used to realize the rotating positioning, which can be referred to the prior art of door and window handle.

[0061] As another embodiment, the limiting part for preventing the free movement of the moving part 3 in the non-operation state can also be directly applied to the moving part 3.

[0062] In the embodiment, the driving part 15 includes the gear 11 and the adjusting shaft 10, the gear 11 cooperates with the rack structure of the driven part 16, the adjusting shaft 10 is connected to the side of the gear 11 close to the transmission bar 1, and the adjusting shaft 10 extends to the first through hole 5. Specifically, the gear 11 in the embodiment is provided with a hexagonal protrusion 22 close to the side of the transmission bar 1, the adjusting shaft 10 is provided with an internal hexagonal mounting hole, the internal hexagonal mounting hole is cooperated and mounted with the hexagonal protrusion 22, to realize the rotation of the gear 11 driven by the adjusting shaft 10. Further, the end of the adjusting shaft 10 away from the gear 11 is provided with an internal hexagonal adjusting hole, which is used to cooperate with the screwing tool, to realize the rotation adjustment of the adjusting shaft 10 and the gear 11, so as to realize the adjustment of the compression degree of the elastic element 2; the internal hexagonal adjusting hole on the adjusting shaft 10 constitutes the operation end of the driving part 15. In addition, the cooperation and mounting between the gear 11 and the adjusting shaft 10 can also adopt other ways of special-shaped structure or other fixed connection structure to realize the connection between the adjusting shaft 10 and the gear 11; of course, the adjusting shaft 10 and the gear 11 can also adopt an integrated structure.

[0063] For the convenience of limiting the rotation angle of the driving piece 15, the mounting box 4 of the embodiment is further provided with a limiting plate 9; the limiting plate 9 is provided with an assembly hole 26, the inner wall of the assembly hole 26 is provided with a first protrusion 27; the adjusting shaft 10 is arranged in the assembly hole 26, and the outer wall of the adjusting shaft 10 is provided with a second protrusion 25, the second protrusion 25 is arranged correspondingly with the first protrusion 27. The axial positions of the first protrusion 27 and the second protrusion 25 of the embodiment are aligned, so that they have overlapping parts, so as to limit the rotation angle of the adjusting shaft 10. Specifically, the adjusting shaft 10 of the embodiment is provided with a plurality of digital gears, for example, 0, 1, 2…, one side of the first through hole 5 is provided with a first observation hole 6, one side of the second through hole 37 is provided with a second observation hole 38, the first observation hole 6 is aligned with the second observation hole 38, and the first observation hole 6 and the second observation hole 38 are aligned with the digital gears, so as to observe the rotation gear or the rotation angle of the adjusting shaft 10, each digital gear corresponds to the gear of the rotation positioning assembly. In addition, the embodiment combines the arrangement of the first protrusion 27 and the second protrusion 25, so as to limit the maximum gear (maximum rotation angle) of the driving piece 15, and avoid the excessive compression of the elastic element 2 caused by the repeated rotation of the driving piece 15. When the gear of the driving piece 15 rotates to the maximum, the first protrusion 27 and the second protrusion 25 are connected, the first protrusion 27 blocks the continuous rotation of the adjusting shaft 10; when the driving piece 15 reversely rotates to reset, the other side of the first protrusion 27 and the second protrusion 25 are connected, so as to position the initial position of the driving piece 15.

[0064] The driving member 15 is provided with a reset hole 23 in the embodiment. The reset hole 23 is arranged on the axis of the driving member 15 and penetrates the driving member 15.

The positioning seat 12 is provided with a guide shaft 28 coaxial with the reset hole 23, and the guide shaft 28 extends into the reset hole 23. When the driving member 15 is rotated to the maximum gear, if it is needed to reset the driving member 15, the driven member 16, the moving member 3 and the elastic element 2 to the initial state, a tool can be inserted into the reset hole 23 from the second through hole 37 on the transmission panel 36 and the first through hole 5 on the transmission strip 1, and the guide shaft 28 is pressed away from the transmission strip 1, so as to drive the positioning seat 12 to move away from the transmission strip 1 against the elastic force of the elastic element 13, until the positioning groove 29 on the positioning seat 12 is separated from the positioning block 24 on the driving member 15. At this time, the driving member 15 is not limited by the positioning seat 12, and is driven by the elastic element 2 to move reversely with the moving member 3, the driven member 16 and the driving member 15, and finally to the initial state. Finally, the positioning seat 12 is released, so that the positioning seat 12 and the driving member 15 are repositioned, and the reset operation is completed. Through the reset hole 23, the reset operation can be completed outside the transmission panel 36, and combined with the structure of the rotary positioning assembly and the elastic force of the elastic element 2, only one pressing action of the guide shaft 28 is needed, which is simple and convenient.

Specifically, the connecting block 34 is arranged in a stepped disc in the embodiment, and the connecting block 34 is arranged in the mounting groove 33 of the butt joint part 8 of the driven member 16.

At the same time, the end of the containing groove 31 is provided with a avoiding hole 32, the avoiding hole 32 is smaller than the elastic element 2, and the avoiding hole 32 corresponds to the mandrel 35, the end of the mandrel 35 is inserted into the avoiding hole 32, so as to move the moving part 3. In addition, in order to prevent the moving part 3 from rotating while moving to improve stability, the mandrel 35 is provided with a plane at a distance from the end close to the fixed support 14, so that the mandrel 35 is a non-circular structure at the end close to the fixed support 14, and the avoiding hole 32 corresponds to the non-circular structure to limit the rotation of the moving part 3.

[0067] The above is only the preferred embodiment of the present application, and does not limit the present application in any form.
