Description

Technical Field

[0001] This utility model relates to the field of plastic buckles, and more specifically, to a plastic buckle anti-detachment structure. Background Technology

[0002] A snap-fit ​​connection is a mechanism used for inserting or locking one part to another, typically used for joining plastic parts. The material used is usually a flexible plastic. The biggest advantage of snap-fit ​​connections is their ease of installation and disassembly, allowing for tool-free removal. Snap-fit ​​connection technology is now widely used in the connection of automotive interior parts.

[0003] In related technologies, to address the problem that current plastic buckles lack an internal anti-detachment structure during engagement, leading to instability and easy detachment of the fastener and buckle, patent CN220668075U provides an anti-detachment structure for plastic buckles. This structure, through an anti-detachment mechanism, uses a rotating bolt to connect its threaded connection to the inside of a fixing plate, positioning the buckle and preventing it from detaching. This makes the buckle more stable inside the fastener. Furthermore, through a spring-loaded engagement mechanism, the buckle engages with a groove on the fastener surface, achieving the desired engagement between the buckle and fastener.

[0004] However, during use, plastic buckles undergo plastic deformation over time, which reduces their resilience and prevents them from falling off. This results in unstable fasteners and clips that are prone to falling off. How to invent a plastic buckle anti-fall-off structure to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a plastic buckle anti-detachment structure, which aims to improve the problem that the buckles and clips are not stable enough and are prone to falling off.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a plastic buckle anti-detachment structure, including a connector, a fastener, and a telescopic sleeve. A snap-fit ​​rod is movably installed on one side of the connector, and a serrated groove is provided on the outer side of the snap-fit ​​rod. A fastener corresponding to the connector is provided on one side of the connector. A limiting tooth that mates with the serrated groove is fixedly installed on the inner side of the fastener. A telescopic sleeve is fixedly installed inside the fastener. A connecting plate is movably installed at one end of the telescopic sleeve. A roller that mates with the inner side of the snap-fit ​​rod is rotatably installed on the outer side of the connecting plate. A pull sleeve extending out of the bottom of the fastener is fixedly installed at the bottom of the connecting plate. A sliding groove for the pull sleeve to slide is provided on the fastener.

[0008] Preferably, the snap-fit ​​rod and the connector are fixedly installed together by a mounting base, and the mounting base and the snap-fit ​​rod are movably installed together by a rotating base.

[0009] By adopting the above technical solution, the inner side of the locking rod contacts the roller, allowing the locking rod to rotate around the rotating seat, allowing the locking rod to flip to both sides, and allowing the first spring between the locking rods to be stretched.

[0010] Preferably, a connecting seat is fixedly installed between the snap-fit ​​rods, and the connecting seats are movably connected to each other by a first spring.

[0011] By adopting the above technical solution, during the docking process between the connector and the fastener, one end of the locking rod can be inserted into the interior of the fastener, and the inner side of the locking rod can contact the roller, allowing the locking rod to rotate around the rotating seat.

[0012] Preferably, the fastener has movable grooves fixedly installed on both sides, and the snap-fit ​​rod is located inside the movable grooves.

[0013] By adopting the above technical solution, the movable groove allows the locking rod to move inside the movable groove, thereby enabling the serrated groove and the limiting tooth to engage and fix the connector and the fastener.

[0014] Preferably, a fixing rod is fixedly installed on the outer side of the connecting plate, and the roller is rotatably installed between the fixing rod and the roller.

[0015] By adopting the above technical solution, under the squeezing action of the second spring, the roller can be squeezed against the inner side of the locking rod when the movable rod is squeezed, so that the locking rod can move inside the movable groove and the limiting tooth can engage with the sawtooth groove.

[0016] Preferably, a movable rod is slidably mounted inside the telescopic sleeve via a sliding plate, one end of the movable rod is fixedly connected to a connecting plate, and the sliding plate is movably connected to the inside of the telescopic sleeve via a second spring.

[0017] By adopting the above technical solution, the sliding plate can slide along the inner side of the telescopic sleeve, and under the squeezing action of the second spring, the movable rod can squeeze the roller and the inner side of the locking rod, so that the locking rod can move inside the movable groove.

[0018] The beneficial effects of this utility model are:

[0019] During the docking process between the connector and the fastener, one end of the locking rod extends into the fastener. The inner side of the locking rod contacts the roller, allowing it to rotate around the rotating seat and flip to both sides. This stretches the first spring between the locking rods, enabling it to slide along the inner side of the telescopic sleeve via the sliding plate. Under the compression of the second spring, the movable rod is pressed, causing the roller to press against the inner side of the locking rod, allowing the locking rod to move within the movable groove. This allows the limiting teeth to engage with the serrated groove, conveniently limiting the connection between the connector and the fastener. Simultaneously, pulling the pulling sleeve allows it to slide along the sliding groove, causing the movable rod mounted on one side of the connecting plate to slide along the inside of the telescopic sleeve. The stretching of the first spring causes the locking rods to move closer together, separating them from the limiting teeth and thus separating the connector from the fastener.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example, refer to Figure 1-6 A plastic buckle anti-detachment structure includes a connector 1, a fastener 2, and a telescopic sleeve 3. A snap-fit ​​rod 102 is movably installed on one side of the connector 1, and a serrated groove 104 is provided on the outer side of the snap-fit ​​rod 102. A fastener 2 corresponding to the connector 1 is provided on one side of the connector 1. A limiting tooth 202 that cooperates with the serrated groove 104 is fixedly installed on the inner side of the fastener 2. A telescopic sleeve 3 is fixedly installed inside the fastener 2. A connecting plate 301 is movably installed at one end of the telescopic sleeve 3. A roller 303 that cooperates with the inner side of the snap-fit ​​rod 102 is rotatably installed on the outer side of the connecting plate 301. A pulling sleeve 308 extending out of the bottom of the fastener 2 is fixedly installed at the bottom of the connecting plate 301. A sliding groove 307 for the pulling sleeve 308 to slide is provided on the fastener 2. The snap-fit ​​rod 102 and the connector 1 are fixedly installed through a mounting base 101. The mounting base 101 and the snap-fit ​​rod 102 are movably installed through a rotating base 103.

[0030] Furthermore, connecting seats 105 are fixedly installed between the snap-fit ​​rods 102, and the connecting seats 105 are movably connected by a first spring 106. Movable grooves 201 are fixedly installed on both sides of the fastener 2, and the snap-fit ​​rods 102 are located inside the movable grooves 201.

[0031] It should be noted that during the docking process between the connector 1 and the fastener 2, one end of the locking rod 102 can be inserted into the interior of the fastener 2. The inner side of the locking rod 102 contacts the roller 303, allowing the locking rod 102 to rotate around the rotating seat 103 and flip to both sides, so that the first spring 106 between the locking rods 102 can be stretched.

[0032] Reference Figure 3-6 Furthermore, a fixing rod 302 is fixedly installed on the outer side of the connecting plate 301, and the roller 303 is rotatably installed between the fixing rod 302. A movable rod 304 is slidably installed inside the telescopic sleeve 3 through the sliding plate 305. One end of the movable rod 304 is fixedly connected to the connecting plate 301, and the sliding plate 305 is movably connected to the inside of the telescopic sleeve 3 through the second spring 306.

[0033] It should be noted that by pulling the pulling sleeve 308, the pulling sleeve 308 slides along the inside of the sliding groove 307, thereby allowing the movable rod 304 installed on one side of the connecting plate 301 to slide along the inside of the telescopic sleeve 3. The tension of the first spring 106 allows the locking rods 102 to move closer to each other, thereby separating the locking rods 102 from the limiting tooth 202, thus separating the connecting piece 1 from the fastener 2.

[0034] The working principle of this plastic buckle anti-detachment structure is as follows: During the docking process between the connector 1 and the fastener 2, one end of the locking rod 102 extends into the interior of the fastener 2. The inner side of the locking rod 102 contacts the roller 303, allowing the locking rod 102 to rotate around the rotating seat 103. This allows the locking rod 102 to flip to both sides, stretching the first spring 106 between the locking rods 102. The sliding plate 305 slides along the inner side of the telescopic sleeve 3. Under the compression of the second spring 306, the movable rod 304 is compressed, causing the roller 303 to contact the inner side of the locking rod 102. The compression allows the locking rod 102 to move inside the movable groove 201, enabling the limiting tooth 202 to engage with the serrated groove 104, thus conveniently limiting the connection between the connector 1 and the fastener 2. Simultaneously, by pulling the pulling sleeve 308, the pulling sleeve 308 slides along the sliding groove 307, allowing the movable rod 304 installed on one side of the connecting plate 301 to slide along the telescopic sleeve 3. The tension of the first spring 106 allows the locking rods 102 to move closer to each other, thereby separating the locking rods 102 from the limiting tooth 202, thus separating the connector 1 from the fastener 2.

[0035] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
