Description

A self-elastic buffer roller Technical Field

[0001] This utility model relates to a self-elastic buffer hanger. Background Technology

[0002] Embedded sliding doors, also known as "pocket doors," are designs that embed the door within the wall, allowing it to be completely hidden when closed. They offer advantages such as aesthetics and space saving. Traditional sliding doors, during opening or closing, often cause the door to slam against the wall due to inertia, resulting in a "smack" sound or pinching fingers. Existing buffer structures install buffers at both ends of the sliding door and fasteners at both ends of the track, using the buffers and fasteners to achieve bidirectional buffering. This structure has many components, making assembly and disassembly cumbersome. Furthermore, when fully open, the door is completely embedded in the wall, making it difficult for users to push the door out when closing, causing inconvenience. Summary of the Invention [Summary of the Utility Model]

[0003] To solve at least one of the above problems, this utility model proposes a new structural solution. The self-elastic buffer pulley adopts the following technical solution:

[0004] A self-springing buffer roller includes a housing, a first buffer rod, a second buffer rod, and a rebound device. The housing has a first linear groove, a second linear groove, and a rebound groove at its two ends, respectively, with the first and second linear grooves aligned on the same straight line. The first buffer rod is installed in the first linear groove, and the second buffer rod is installed in the second linear groove. Both the first and second buffer rods have actuating elements installed at their movable ends, with the actuating elements facing opposite directions. The rebound device is installed in the rebound groove, and the rebound groove has an energy storage buckle connected to the rebound device.

[0005] Preferably, a wheel is pivotally connected to the front end of the housing, and a pulley is locked to the rear end of the housing.

[0006] Preferably, a first docking portion extends from the end of the housing, and a second docking portion extends from the end of the pulley. Both the first and second docking portions are L-shaped, and the housing and the pulley are linked together by hooking the first and second docking portions.

[0007] Preferably, both the first docking part and the second docking part are provided with locking holes. The locking hole of the first docking part extends through the first docking part, while the second docking part is a blind hole. The pulley cart is equipped with screws that pass through the locking holes of both the first docking part and the second docking part to fix the housing and the pulley cart together.

[0008] Preferably, the pulley cart includes a cart body and wheels. The cart body has several recesses, and the wheels are pivotally connected to the recesses via axles. Part of the wheels protrude from the bottom surface of the cart body to support the cart body.

[0009] The beneficial effects of this utility model compared with the prior art are:

[0010] This structure features a first and a second linear slide groove on the housing, with a first and a second buffer rod respectively positioned on each groove. The first and second buffer rods are oriented in opposite directions, ensuring cushioning when the sliding door moves left or right. A wheel is pivotally connected to one end of the housing, and a pulley is fastened to the other. The pulley and wheel are detachable, allowing for adjustment of the overall length and facilitating operation in narrow spaces. The first and second docking parts are interlocked. To disassemble, remove the connecting screw in the lock hole, rotate the pulley to change its position, and then move it upwards to detach it from the second docking part. This reduces the overall length, making it easier to remove the housing portion. In addition, the casing is equipped with a spring-loaded groove containing a rebound mechanism. The rebound mechanism connects to the energy storage buckle. A stop block is provided in the wall. After the door is fully embedded in the wall, the stop block abuts against the end of the energy storage buckle, causing the rebound mechanism to contract under pressure and shorten its length. When the door needs to be moved out, pressing inward resets the rebound mechanism, extending its length, and the door is then pushed out using the rebound mechanism. It boasts advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. Figure Description

[0013] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] The preferred embodiment of this utility model is shown in Figures 1 and 2. A self-springing buffer roller includes a housing 1, a first buffer rod 2, a second buffer rod 3, and a rebounder 4. The two ends of the housing 1 are respectively provided with a first linear groove 11, a second linear groove 12, and a rebound groove 13. The first linear groove 11 and the second linear groove 12 are arranged on the same straight line. The first buffer rod 2 is installed in the first linear groove 11, and the second buffer rod 3 is installed in the second linear groove 12. The movable ends of both the first buffer rod 2 and the second buffer rod 3 are equipped with actuating elements 5, and the actuating elements 5 of the first buffer rod 2 and the second buffer rod 3 face opposite directions. The rebounder 4 is installed in the rebound groove 13, and the rebound groove 13 is provided with an energy storage buckle 6, which is connected to the rebounder 4.

[0017] A wheel is pivotally connected to the front end of the housing 1, and a pulley 7 is locked to the rear end of the housing 1. The pulley 7 includes a body 71 and a wheel 72. The body 71 is provided with several recesses 73. The wheel 72 is pivotally connected to the recesses 73 via an axle. The wheel 72 partially protrudes from the bottom end face of the body 71 to support the body 71.

[0018] A first docking portion 14 extends from the end of the housing 1, and a second docking portion 15 extends from the end of the pulley trolley 7. Both the first docking portion 14 and the second docking portion 15 are L-shaped and are hooked together to enable the housing 1 and the pulley trolley 7 to move together. Both the first docking portion 14 and the second docking portion 15 are provided with locking holes 16. The locking hole 16 of the first docking portion 14 passes through the first docking portion 14, while the second docking portion 15 is a blind hole. The pulley trolley 7 is equipped with screws that pass through the locking holes 16 of both the first docking portion 14 and the second docking portion 15 to fix the housing 1 and the pulley trolley 7 together.

[0019] Traditional sliding doors often slam against the wall during opening or closing due to inertia, causing a "smack" sound or trapping hands. To address this inertia issue, this structure incorporates a first and second linear slide rail in the housing, with a first and second buffer rod installed on each rail respectively. These buffer rods are oriented in opposite directions, providing cushioning when the door moves left or right. A wheel is pivotally connected to one end of the housing, while a pulley is attached to the other. The pulley and wheel are detachable, allowing for length adjustment and easier operation in narrow spaces. The first and second connecting parts are interlocked. To disassemble, remove the connecting screw in the lock hole, rotate the pulley to change its position, and then move it upwards to detach it from the second connecting part. This reduces the overall length, making it easier to remove the housing section. To address the issue of the sliding door being difficult to push out once fully opened and embedded in the wall, a spring-loaded groove is added to the casing. A rebound mechanism is installed within this groove; existing cabinet door rebound mechanisms can be used. The rebound mechanism 4 is connected to the energy storage buckle 6. The actuating component 5 has protrusions 51 at both ends, with a recess 52 between them. The end faces of the protrusions 51 are beveled to facilitate the movement of the locking block into or out of the recess 52. The locking block connected to the actuating component is a commonly used component in existing sliding door parts. Locking blocks, stops, and rebound mechanism parts can be found on e-commerce platforms, so their structure will not be described in detail here. With a stop in the wall, after the door is fully embedded, the locking block abuts against the end of the energy storage buckle, causing the rebound mechanism to contract and shorten. When the door needs to be moved out, pressing inward resets the rebound mechanism, extending its length, allowing the door to be pushed out. The depths of the first linear slide 11, the second linear slide 12, and the springback groove 13 are greater than the heights of the energy storage buckle and the actuating component, so as to provide space for the energy storage buckle and the actuating component to move. The energy storage buckle and the actuating component are exposed outside their respective channels for easy connection.
