Description

Technical Field

[0001] This utility model relates to the field of quick-installation fixing technology, and more specifically, to a quick-installation locking assembly and quick-installation plate. Background Technology

[0002] To improve the utilization of roof space, more and more users are opting to install storage boxes on their vehicles, among which rotomolded boxes are widely used due to their excellent molding performance and structural strength. However, in practical applications, the installation and fixation of rotomolded boxes still face significant technical challenges: on the one hand, traditional installation methods often suffer from inconvenience in disassembly and assembly, failing to meet users' needs for convenience; on the other hand, due to the dynamic loads such as wind resistance and vibration during vehicle operation, improper installation structure design can easily lead to rotomolded boxes shaking or even falling off, posing serious safety hazards.

[0003] Currently, quick-release plates are widely used as a key component connecting the rotomolded box to the vehicle roof. These plates not only need to be easy to install and remove, but also must ensure structural stability after installation to effectively suppress vibration and displacement of the rotomolded box during vehicle operation. Therefore, designing a quick-release plate structure that combines ease of installation and removal with robust installation is a consistently hot topic in the industry.

[0004] Patent CN215291978U discloses a locking device and a fixing bracket. The locking device includes a driving component, a latch assembly, a resilient locking hook assembly, and a fixing base. The latch assembly is pivotally connected to the driving component via a pin. The end of the latch assembly away from the pin has a hook portion adapted to a snap-fit ​​portion on the object to be fixed. The latch assembly rotates around the pin under the drive of the driving component, causing the hook portion to disengage from or hook onto the snap-fit ​​portion. The resilient locking hook assembly is mounted on the driving component and locks the latch assembly when the hook portion hooks onto the snap-fit ​​portion, thus fixing the latch assembly and the driving component. This design can also be applied to the quick installation of roof storage boxes, but there is still room for improvement in its ease of use. Utility Model Content

[0048] The present invention will be further described below with reference to the embodiments.

[0049] Example

[0050] Combination Figures 1-9 As shown, a quick-release locking assembly of this embodiment includes: a fixing base 210, with a pivot mounting position at one end; a pressing part 234, one end of which has a locking part 235 adapted to a buckle 301 on the object to be fixed, and the other end of which has a pivot mounting position; a connecting plate 232, which is installed between the fixing base 210 and the pressing part 234, and one end of the connecting plate 232 is pivotally connected to the pivot mounting position on the fixing base 210 via a connecting shaft 231, and the other end of the connecting plate 232 is connected to the pivot mounting position on the pressing part 234 via a connecting shaft 233. 31. The central axes of the connecting shaft 233 and the engaging part 235 are kept parallel. Specifically, when the engaging part 235 locks the object to be fixed, the connecting shaft 231 is located between the engaging part 235 and the connecting shaft 233, and the axis of the connecting shaft 233 is offset from the extension direction of the line b connecting the axes of the connecting shaft 231 and the engaging part 235, and is located on the side of the line b closer to the fixing seat 210. The angle between the line c connecting the axes of the connecting shaft 231 and the connecting shaft 233 and the line b is 10°-30°, more preferably 20°-30°, and can be 10°, 15°, 20°, 25°, 30°, etc.

[0051] In this embodiment, a fixed storage box 300 is used as an example. The storage box 300 is provided with an outwardly protruding buckle 301. The engaging part 235 can adopt a pin structure. A groove structure for the pin shaft to be engaged downward is formed in the buckle 301. The engaging part 235 and the buckle 301 can also adopt other structural forms for hooking and engaging, etc., which will not be described in detail. Due to the pivotal design of connecting shaft 1 231 and connecting shaft 233, the pressing part 234 can flexibly rotate around connecting shaft 1 231 and connecting plate 232. In practice, both connecting shaft 1 231 and connecting shaft 233 can adopt a single long shaft structure, that is, hanging ears are respectively provided on both sides of the fixing base 210, and the two hanging ears are connected by a single connecting shaft 1 231. Connecting plates 232 are connected to both ends of connecting shaft 1 231, and the other ends of the two connecting plates 232 can be connected by a single connecting shaft 233. The two ends of connecting shaft 233 are respectively connected to the hanging ears on both sides of the pressing part 234. Other pivoting connection methods can also be adopted, such as connecting the connecting plate 232 to the lugs on both sides of the fixed base 210 with a short pin, and connecting the ends of the connecting plates 232 on both sides to the lugs on both sides of the pressing part 234 with a short pin, etc., in order to form a double-link hinge structure, so that the pressing part 234 can rotate around the connecting plate 232, and the connecting plate 232 can rotate flexibly around the fixed base 210.

[0052] In practice, the side wall of the fixed base 210 facing the pressing part 234 is also provided with a limiting part 223. When locking the object to be fixed, the connecting shaft 233 cooperates with the limiting part 223 to press and limit.

[0053] In this embodiment, the pressing part 234 has a pre-tightening position and a locking position when pressed down, specifically combined with... Figure 10 As shown, taking the pressing part 234 flipping upwards to engage the pin-shaped engaging part 235 with the buckle 301 as an example, Figure 10In state A, the pressing part 234 flips upward, causing the engaging part 235 to hook with the buckle 301. In state B, the pressing part 234 is pressed downward and flipped, causing the hook pin to gradually tighten with the buckle 301. In state C, the pressing part 234 is in the pre-tightened position. At this time, the engaging part 235, connecting shaft one 231, and connecting shaft two 233 are on the same plane, that is, the axis connecting the three shafts is collinear, that is, the three points form a line connecting the line a. At this time, it is at the dead point position with the maximum tension. Connecting shaft one 231 is at the engaging part 235. Between 35 and connecting shaft 233, state D is the locked position after pressing down past the dead point. At this time, connecting shaft 233 rotates downward past the dead point, forming a line c between the axis of connecting shaft 1 231 and the axis of connecting shaft 233, and a line b between the axis of engaging part 235 and the axis of connecting shaft 1 231. Line c is located below line b, making the axes of the three shafts triangularly distributed. At this time, connecting shaft 233 is fastened and limited by limiting part 223, preventing further pressing and achieving a fully locked state. To unlock, flip the pressing part 234 upward to disengage connecting shaft 233 from limiting part 223, and then continue flipping to disengage engaging part 235 from buckle 301.

[0054] It should be noted that in practice, the requirements for the tightness and stability of quick-release locking structures are becoming increasingly stringent. Traditional locking structures are prone to issues such as not being able to fasten tightly, requiring significant pressure, or being easily loosened or popped open, resulting in poor stability. In this embodiment, through precise adjustment of the fit between the various components, the connecting shaft 233 can be flipped past the pre-tightening position of the three collinear axes and then engage with the limiting part 223 to fasten. The angle between connecting line c and connecting line b is strictly controlled when locked. In practice, this design effectively enhances the tensioning effect between the engaging part 235 and the buckle 301, and ensures that the pressing part 234 is fully pressed, preventing the pressing part 234 from easily popping open and loosening. The pressing force is also appropriate, facilitating quick operation by the user. In practice, the locking assembly 200 can also be reversed, with the engaging part 235 facing downwards and hooking into the corresponding buckle 301 on the storage box 300, and then flipped upwards to achieve tightening. The principle is the same as above and will not be elaborated further.

[0055] To further enhance application security, a lock cylinder 237 is also provided inside the pressing part 234. A lock plate 236 is located on the side of the lock cylinder 237 facing the fixing base 210. The lock cylinder 237 can drive the lock plate 236 to rotate synchronously. A corresponding lock hook 222 is provided on the fixing base 210 to cooperate with the lock plate 236. Rotating the lock cylinder 237 allows the lock plate 236 to hook or disengage from the lock hook 222, achieving locking and unlocking. In the locked state, the lock plate 236 is blocked by the lock hook 222, preventing it from flipping upwards to open the pressing part 234, further improving the lock's security and preventing accidental opening or popping open.

[0056] As a preferred implementation, the pressing part 234 is further provided with a hook-and-loop engagement part 235 and a connecting shaft 233 at both ends, and the distance between the engagement part 235 and the pressing part 234 is greater than the distance between the connecting shaft 233 and the pressing part 234. The locking piece 236 is installed between the engagement part 235 and the connecting shaft 233, and the distance between the locking piece 236 and the pressing part 234 exceeds the connecting shaft 233. The locking piece 236 can be flipped from the outside of the connecting shaft 233 and engage with the locking hook 222. More specifically, the pressing part 234 has two side lugs 238 near the engaging part 235, with the engaging part 235 installed between the two side lugs 238; the pressing part 234 has two side lugs 239 near the connecting shaft 233, with the connecting shaft 233 installed on the two side lugs 239. Both the first lug 238 and the second lug 239 are located on the wall surface of the pressing part 234 near the fixing seat 210, and the extension length of the first lug 238 is greater than the length of the second lug 239, so that the distance between the engaging part 235 and the pressing part 234 is greater than the distance between the connecting shaft 233 and the pressing part 234. This creates an installation area for the lock cylinder 237 and the lock plate 236 inside the pressing part 234, and provides space for the lock plate 236 to protrude inwards, facilitating flexible engagement between the lock plate 236 and the lock hook 222. Furthermore, the locking plate 236 can be flipped off the connecting shaft 233 and engage with the locking hook 222. The locking plate 236 is not obstructed when flipping, nor does it affect the free flipping of the pressing part 234 and the locking plate 236. The overall structure is relatively compact, which can save material costs. Furthermore, the inner and outer sides of the first hanging ear 238 and the pressing part 234 are smoothly transitioned by arc surfaces, and the inner and outer sides of the second hanging ear 239 and the pressing part 234 are also smoothly transitioned by arc surfaces. When the pressing part 234 is flipped and pressed, the end of the connecting plate 232 is also a smooth arc-shaped wall surface, which can adapt to the arc-shaped transition area formed between the first hanging ear 238 and the pressing part 234 to ensure a full pressing effect and to simplify the product space layout as much as possible.

[0057] Alternatively, in practice, the locking hook 222 and the limiting part 223 can be integrally stamped. The locking hook 222 extends outward from the wall of the fixing seat 210 and then bends towards the connecting shaft 231. The end of the locking hook 222 away from the connecting shaft 231 has the limiting part 223, which is an outwardly protruding arc-shaped wall surface. This integral stamping process is simple to manufacture and has a compact structure, while providing both limiting and locking / unlocking functions.

[0058] To ensure that the pressing part 234 can effectively and quickly reset during the unlocking operation, an elastic reset element, such as a reset spring, can be optionally provided between the fixed base 210 and the connecting shaft 233. One end of the elastic reset element abuts against the fixed base 210, and the other end extends towards the connecting shaft 233. This not only further increases the preload during the locking phase but also facilitates quick reset during unlocking. Especially when the engaging part 235 is facing downwards and hooks into the corresponding latch 301 on the storage box 300, it helps prevent the engaging part 235 from remaining hooked to the latch 301 on the storage box 300 after unlocking, thus avoiding affecting the user's operational convenience.

[0059] In practice, it is preferable that the fixing base 210, connecting shaft one 231, connecting shaft two 233 and engaging part 235 are all metal parts to ensure sufficient structural strength and stability, while the pressing part 234 is a plastic molded part that can be integrally molded with the lock cylinder 237, which is convenient to process, saves costs, and also helps to improve the user's operating experience.

[0060] This embodiment also provides a quick-release plate, including a main panel 101. The main panel 101 supports the object to be fixed. The main panel 101 is provided with a locking assembly 200 as described above. When the locking assembly 200 is fastened, the engaging portion 235 corresponds to and engages with the buckle 301 on the object to be fixed. Furthermore, the main panel 101 is provided with panel limiting portions 102 in both the width and length directions surrounding the object to be fixed, to limit the width and length of the object. Specifically, the panel limiting portion 102 can be a protruding limiting block structure that blocks the periphery of the object to be fixed, or it can be a groove structure that adapts to the protruding structure on the object to be fixed for limiting, etc., which will not be described in detail. Figure 2 The main panel 101 has a panel limiting part 102 on each of its left and right sides. In use, the panel limiting parts 102 clamp the storage box 300 from both sides to prevent it from wobbling in the width direction. Two sets of panel limiting parts 102 are symmetrically arranged at the front center of the main panel 101, and the locking assembly 200 is located between the two sets of front panel limiting parts 102. In use, two quick-release plates 100 are respectively installed at both ends of the length direction of the storage box 300, thereby cooperating to limit the length of the storage box 300 and prevent wobbling.

[0061] In practice, the mounting base 210 can be implemented in various ways. For example, the mounting base 210 includes a mounting plate 211, with a base plate 215 on one side of the lower part of the mounting plate 211. The base plate 215 has mounting holes for bolt fastening to the main panel 101. The other side of the lower part of the mounting plate 211 has a limiting leg 221. The main panel 101 has a mounting slot 104 that matches the limiting leg 221. The limiting leg 221 is embedded in the mounting slot 104 and positioned. Specifically, two sets of mounting holes can be opened on the base plate 215, and the limiting leg 221 is located on the central axis of the two sets of mounting holes. The limiting leg 221 at one end is used for pre-positioning, and then bolt fastening is performed to achieve three-point support, resulting in a stable structure.

[0062] Furthermore, the fixing base 210 is a metal part, and the fixing plate 211, the base plate 215, and the limiting foot 221 are all independent components. The fixing plate 211 is fixed above the base plate 215, and the fixing plate 211 and the base plate 215 are provided with corresponding through grooves. One side of the through plate 219 passes through the through groove and is fixed, while the bottom of the other side has a limiting foot 221. More specifically, the lower part of the fixing plate 211 is detachably connected to the main panel 101 through the base plate 215 for easy disassembly and replacement. The upper two sides of the fixing plate 211 are provided with hanging ears, and the hanging ears are provided with shaft holes 212 for installing the connecting shaft 231. The bottom side of the fixing plate 211 facing away from the connecting shaft 231 has a limiting foot 221. The main panel 101 is provided with a mounting slot 104 that matches the limiting foot 221, and the limiting foot 221 is embedded in the mounting slot 104 and positioned.

[0063] Combination Figure 8 As shown, the bottom plate 215 has an upwardly extending vertical plate 216 at its end. A fixing plate 211, a vertical plate, is welded to one side of the vertical plate 216, and a limiting support 221 is welded and fixed to the other side of the vertical plate 216. Specifically, the fixing plate 211 has a through hole 213 that extends through the entire thickness, which can be used as a welding operation hole to weld with the vertical plate 216. The lower part of the fixing plate 211 has a downwardly extending vertical groove 214, and the corresponding area of ​​the bottom plate 215 has a horizontal groove 217. The corresponding area of ​​the lower part of the vertical plate 216 has a second vertical groove 218 that communicates with the horizontal groove 217. After the fixing plate 211 and the vertical plate 216 are fixed, the positions of each groove correspond, thus forming a slot for the through plate 219 to pass through. The bottom of the through plate 219 has a downwardly protruding limiting boss 220 that cooperates with and positions the horizontal groove 217. Figure 8 In terms of orientation, when the through plate 219 is inserted into the slot from left to right, the limiting boss 220 abuts against the end of the transverse groove 217 and is in place. The right side of the through plate 219 is inserted into the slot and welded in the same way. The bottom left side of the through plate 219 has a limiting support 221, which, in conjunction with... Figure 3As shown, the limiting foot 221 is inserted downwards into and protrudes from the mounting slot 104 on the main panel 101, so that the side wall of the through plate 219 is in place when it abuts against the end of the mounting slot 104. When installing the fixing base 210, one end is first positioned using the limiting foot 221 and the mounting slot 104. Then, two sets of mounting holes 103 are provided on the main panel 101, and corresponding mounting holes are provided on the base plate 215. The mounting can be easily secured with bolts.

[0064] Furthermore, in practice, an outer cover 240 may be provided on the outer side of the main panel 101 surrounding the latch assembly 200. The outer cover 240 is detachably installed from the main panel 101, and the outer cover 240 exposes the pressing operation area of ​​the pressing part 234.
