Description

Technical Field

[0001] This application relates to the field of hardware accessories technology, specifically to a convenient assembly spring-loaded mechanism and its application in the field of slide rail technology. Background Technology

[0002] In recent years, drawer slides with automatic spring-back or slow-closing functions have been widely used in cabinets, office furniture, and home systems due to their advantages such as convenient operation, safety, and quiet operation.

[0003] In drawer slides with spring-loaded mechanisms, automatic drawer reset or soft closing is typically achieved through the linkage between a lever mounted on the inner rail and the spring-loaded mechanism. However, traditional spring-loaded mechanisms are complex, with numerous parts, often requiring specialized tools and skills for assembly. The same issue exists with the levers, which are often installed using screws or riveting, making assembly cumbersome.

[0004] Therefore, existing slide rail structures are not only costly to manufacture and assemble, but also limit their applicability in home DIY installation scenarios. For ordinary users, the complex installation process often makes it difficult to correctly assemble the slide rails, thus affecting the normal functioning of the product. Summary of the Invention

[0005] In response to the above-mentioned needs, this application provides a conveniently assembled spring-back mechanism and its application in a slide rail, aiming to overcome the problems of complex assembly, error-proneness, and difficult maintenance in the prior art, and improve the assembly efficiency and reliability of the slide rail system.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] In the first aspect, this application proposes a spring-loaded mechanism that is easy to assemble, which can slide into the outer rail guide rail and be fixed to the outer rail;

[0008] It includes a bracket that can be fixed to an outer rail, a slider, and a pusher arm that can move along a guide rail. The bracket is provided with a guide groove, and the pusher arm can push the slider to move along the guide groove.

[0009] It also includes a return spring disposed between one end of the bracket and the push arm to apply a restoring force to the push arm.

[0010] Thus, by adopting a modular insert structure, the spring mechanism of this application can be slid into the outer rail as a whole and fixed in place, thereby achieving stable installation. This effectively simplifies the cumbersome assembly process of traditional spring components and improves production efficiency and assembly consistency.

[0011] Meanwhile, a stable linkage is formed between the bracket and the push arm through the guide rail, which controls the movement of the slider in the guide groove, ensuring the stability and response accuracy of the rebound action, thereby reducing the noise of unlocking and locking.

[0012] In some possible implementations, one end of the bracket and the push arm are respectively provided with mounting grooves for fixing the two ends of the rebound spring.

[0013] In some possible implementations, the number of the rebound spring and the corresponding mounting groove is two, respectively disposed on both sides of the guide groove.

[0014] In some possible implementations, the bracket is provided with a plurality of through holes that are fixedly connected to the outer rail.

[0015] In some possible implementations, the guide groove is provided at both ends with stop grooves that can lock the slider.

[0016] In some possible implementations, the stop groove on the compression direction side of the rebound spring is provided with a limiting rod.

[0017] In some possible implementations, the push arm is provided with an unlocking groove that allows the guide slider to disengage from the stop groove.

[0018] In some possible implementations, the slider includes a guide portion that clamps the bracket and a force-receiving portion that can be fitted into the release groove.

[0019] Secondly, this application proposes a slide rail using the rebound mechanism described above, including an outer rail, a middle rail, and an inner rail, wherein the inner rail is provided with a lever that can push the slider away from the limit position.

[0020] In some possible implementations, the lever is provided with a slot that can engage with the inner rail fold. Attached Figure Description

[0029] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0030] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0031] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0032] Please refer to Figure 1 and Figure 2 The drawer slide of this application includes an outer rail 1, a middle rail 2, and an inner rail 3. A spring-back mechanism 100 is provided at the outer end of the outer rail 1. The outer rail 1 has a first ball bearing track 11, which moves within a guide rail 12 of the outer rail 1, while the middle rail 2 moves along the inner side of the first ball bearing track 11. The first ball bearing track 11 has multiple steel balls, which facilitate smooth sliding. Using steel balls for sliding is a common technique in the drawer slide industry and will not be described in detail here.

[0033] It should be noted that the guide rail 12 is formed by bending the side of the outer rail 1, and a guide rail 12 is also formed in the middle rail 2. In this embodiment, the guide rail 12 will be referred to as the same reference numeral in the drawings. Furthermore, the middle rail 2 is also provided with a second ball bearing track 21 that moves within its guide rail 12, and the inner rail 3 slides within the second ball bearing track 21.

[0034] Please combine Figures 1 to 4Specifically, the sliding limitation method of the first ball bearing track 11 on the outer rail 1 will be described. At the outer end, it is limited by the folded edge 22 of the middle rail 2, thus synchronously approaching the springback mechanism 100 with the middle rail 2. It should be noted that the folded edge 22 is a retaining edge formed by bending from the bottom of the track. The outer rail 1, middle rail 2, and inner rail 3 all have folded edges 22, which will be referred to as folded edge 22 in this embodiment. On the inner side, the movement of the first ball bearing track 11 in the inner direction is limited by the folded edge 22 at the inner end of the outer rail 1. Therefore, combined with the folded edge 22 at the outer end of the middle rail 2, the movement of the middle rail 2 in the inward and outward directions can be limited.

[0035] Furthermore, buffer pads 23 are provided at both ends of the first ball track 11. The buffer pads 23 mainly play a buffering role when they come into contact with the folded edge 22. The same method is used in the second ball track 21. This is a common technical means in the industry. The details of the second ball track 21 will not be elaborated here.

[0036] Furthermore, the second ball track 21 can slide outward to the springback mechanism 100, while its inner end is restricted by the folded edge 22 of the middle track 2. On the inner side of the inner track 3, the folded edge 22 also limits the movement of the middle track 2. At the outer end of the inner track 3, a lever 200 is provided to drive the springback mechanism 100.

[0037] The above describes the working stroke and limiting method of the slide rail. Based on this, the main problem in the existing technology is the difficulty in installing the spring-back mechanism 100 and the lever 200 during assembly. For this, please refer to... Figure 7 The lever 200 of this application is provided with a slot 210 that can be inserted into the inner rail 3 folded edge 22, which greatly reduces the difficulty of installation by eliminating the need for riveting.

[0038] Please refer to Figures 3 to 6 Specifically, the conveniently assembled spring-loaded mechanism 100 of this application can slide into the guide rail 12 of the outer rail 1 and be fixed to the outer rail 1. Specifically, it includes a bracket 110 that can be fixed to the outer rail 1, and the bracket 100 is provided with a plurality of through holes 111 that are fixedly connected to the outer rail 1.

[0039] It also includes a slider 120 and a pusher arm 130 that can move along the guide rail 12. The bracket 110 is provided with a guide groove 112, and the pusher arm 130 can push the slider 120 to move along the guide groove 112.

[0040] Furthermore, it also includes a return spring 140 disposed at one end of the bracket 1, that is, between the outer end of the outer rail 1 and the push arm 130, and applying a restoring force to the push arm 130. The return spring 140 is installed by having mounting grooves 113 at one end of the bracket 110 and the push arm 130 respectively, which can fix both ends of the return spring 140. The return spring 140 adopts a spring structure with recesses at both ends, which can be inserted into the mounting grooves 113. It should be noted that the mounting grooves 113 of the bracket 110 and the push arm 130 have the same functional structure, therefore, in this embodiment, they will be referred to as mounting groove 113 by the same reference numeral. There are two return springs 140 and corresponding mounting grooves 113, respectively disposed on both sides of the guide groove 112.

[0041] Thus, by adopting a modular insertion structure, the springback mechanism 100 of this application can be slid into the outer rail 1 along the guide rail 12 and fixed as a whole, thereby completing a stable installation. This effectively simplifies the cumbersome assembly process of traditional springback components and improves production efficiency and assembly consistency.

[0042] Meanwhile, the bracket 110 and the push arm 130 form a stable linkage relationship through the guide rail 12, and control the movement of the slider 120 in the guide groove 112, ensuring the stability and response accuracy of the rebound action, thereby reducing the noise of unlocking and locking.

[0043] The specific unlocking and locking mechanisms are described below. Both ends of the guide groove 112 are respectively provided with stop grooves 114 for locking the slider 120. At this time, the push arm 130 is provided with an unlocking groove 131 that guides the slider 120 to disengage from the stop groove 112. The slider 120 includes a guide portion 121 that clamps the bracket 110 and a force-receiving portion 122 that can be fitted into the unlocking groove 131. Please refer to the reference. Figure 8 The pusher 200 pushes the push arm 130 to apply driving force, causing the slider 120 to disengage from the stop groove 114 through the unlocking groove 131 and release the limit. Further, the stop groove 114 on the compression side of the spring 140 is provided with a limiting rod 115. When the spring 140 is compressed, the limiting rod 115 elastically deforms, allowing the slider 120 to enter the stop groove 114. After entering the stop groove 114, the slider 120 resets to limit the slider 120 from sliding out of the stop groove 114.

[0044] Specifically, the lever 200 is provided with a guide groove 220 and a first limiting groove 221 and a second limiting groove 222. When the slide rail retracts, the slider 120 slides through the guide groove 220 to the first limiting groove 221 to release the limit. After the retraction is completed, the slider is limited by the double protection of the first limiting groove 221 and the second limiting groove 222 combined with the action of the limiting rod 115.

[0045] As stated above, this case protects a conveniently assembled spring-loaded mechanism and the slide rails used in its application. All technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
