Description

Rebounder Technical Field

[0001] The present application relates to the technical field of rebounders, and in particular to a rebounder. Background Art

[0002] A rebounder is a furniture hardware accessory used in place of handles to open and close cabinet doors. Unlike handles, which are mounted on the cabinet's surface, rebounders are attached to the cabinet's side panels, adding a more aesthetically pleasing appearance. When the door is closed, the rebounder locks the panel by attracting an iron block and a magnet. Pressing the door causes the elastic structure within the rebounder to push the telescopic element out, allowing the panel to open.

[0003] However, after the rebounder is installed, it is difficult to adjust and the adjustment range is limited, which makes it difficult to meet the needs of adjusting larger door gaps.

[0133] In order to make the objectives, technical solutions, and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and examples. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. This application will be described in detail below with reference to the accompanying drawings and in conjunction with the examples.

[0134] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0135] The following provides an explanation of the terms used in this application.

[0136] Rebounder: A spring-loaded device used to control the opening and closing of furniture such as doors, cabinets, or covers. Rebounders can be installed on the side panels of cabinets to improve the aesthetics and convenience of furniture.

[0137] To facilitate those skilled in the art to understand the technical solutions provided in the embodiments of the present application, the following describes the relevant technologies:

[0138] A rebounder is a furniture hardware accessory used in place of handles to open and close cabinet doors. Unlike handles, which are mounted on the cabinet's surface, rebounders are attached to the cabinet's side panels, adding a more aesthetically pleasing appearance. When the door is closed, the rebounder locks the panel by attracting an iron block and a magnet. Pressing the door causes the elastic structure within the rebounder to push the telescopic element out, allowing the panel to open.

[0139] However, the applicant has learned that the rebounder is difficult to adjust after installation and has a limited adjustment range, making it difficult to meet the need for adjusting a larger door gap.

[0140] To this end, an embodiment of the present application provides a rebounder. The rebounder of the embodiment of the present application can adjust the relative position of the core and the mounting base in both directions by adjusting the nut, thereby adjusting the relative distance between the locking member and the locking base. After installation, the door gap can be adjusted quickly and easily, and a wide adjustment range is provided. Details are described below.

[0141] Hereinafter, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0142] As shown in Figures 1 to 13, the rebounder can include a locking member 1. The locking member 1 can be secured to a locking base 2 mounted at a corresponding position on the door panel using a snap-fit ​​structure, thereby locking the door panel. The locking member 1 can adjust the relative distance between itself and the locking base 2 via a screw-fit structure, thereby adjusting the door gap.

[0143] The respective structures and matching relationship of the locking member 1 and the locking base 2 will be described below.

[0144] The locking member 1 can be installed on the side panel.

[0145] The locking base 2 can be installed at a corresponding position on the inner side of the door panel.

[0146] The locking member 1 includes a core, a mounting base 11, and an internally threaded adjustment nut 18. A retractable claw 131 is provided at the end of the core near the locking base 2. The claw 131 is used to clamp the locking base 2 on the door panel, allowing the locking member 1 to lock the locking base 2, thereby locking the door panel.

[0147] The end of the mounting base 11 away from the locking base 2 is provided with a retaining portion 114, which is used to clamp the adjusting nut 18. Correspondingly, the end of the core body away from the locking base 2 is a threaded end 163, which is slidably mounted on the mounting base 11, and the adjusting nut 18 can be screwed into the threaded end 163.

[0148] In this embodiment, rotating the adjusting nut 18 adjusts its relative position to the threaded end 163, i.e., bidirectionally adjusting the relative position of the core and the mounting base, thereby adjusting the relative distance between the locking member and the locking base, and expanding the adjustment range of the door gap (-4 mm to +4 mm). It can be seen that the rebounder of the embodiment of the present application can quickly and easily adjust the door gap after installation, and provides a wide door gap adjustment range.

[0149] It should be noted that the model and shape of the adjusting nut 18 can be selected according to specific needs, such as a toothed nut or a hexagonal nut, to further reduce the difficulty of adjustment.

[0150] The internal structure of the retaining portion 114 and its coordination with other components will be further described below.

[0151] In an alternative embodiment, as shown in Figures 1 to 3, the retaining portion 114 may include two arcuate side walls 1141, which may be formed by extending from two opposing side panels of the mounting base 11. The two arcuate side walls 1141 are spaced apart to form an opening 1142, through which the toothed surface of the adjusting nut 18 is partially exposed.

[0152] The retaining portion 114 may further include a first clamping plate 1143 and a second clamping plate 1144. The first clamping plate 1143 and the second clamping plate 1144 are spaced apart on the arcuate sidewall 1141, and the spacing between the first clamping plate 1143 and the second clamping plate 1144 can be adapted to the thickness of the adjusting nut 18 so as to clamp and fix the adjusting nut 18 axially.

[0153] In this embodiment, the two arcuate side walls 1141 are adapted to the side shapes of the adjusting nut 18, which can radially fix the adjusting nut 18 and prevent the adjusting nut 18 from accidentally moving or loosening. The opening 1142 formed by the two arcuate side walls 1141 can partially expose the adjusting nut 18 outside the retaining portion 114, allowing the user to directly operate the adjusting nut 18, improving the usability of the adjusting nut 18, and thus improving the convenience of adjusting the door gap. The arcuate side wall 1141 is also provided with a first clamping plate 1143 and a second clamping plate 1144 spaced apart at a distance, which are used together to clamp and axially fix the adjusting nut 18, which can further alleviate the accidental movement or loosening of the adjusting nut 18, thereby improving the overall structural stability of the rebounder.

[0154] In some embodiments, the retaining portion 114 may further include a convex wall, which is formed by extending from the end of the mounting base 11 and can effectively protect internal components from corrosion.

[0155] In an alternative embodiment, as shown in Figures 2 to 4, two first clamping plates 1143 may be included, with the two first clamping plates 1143 extending from the two curved side walls 1141, respectively, and the gap between the two first clamping plates 1143 may form a first passage 1145. Correspondingly, two second clamping plates 1144 may be included, with the two second clamping plates 1144 extending from the two curved side walls 1141, respectively, and the gap between the two second clamping plates 1144 may form a second passage 1146.

[0156] In this embodiment, a first passage 1145 and a second passage 1146 are provided for the threaded end 163 to pass through, so as to adjust the relative position of the adjusting nut 18 and the threaded end 163, that is, to adjust the relative position of the core body and the mounting base 11 in both directions, so that the core body can smoothly move away from or approach the end of the mounting base 11.

[0157] In an optional embodiment, as shown in Figures 1 to 5, the locking member 1 further includes a nut support seat 19, on which a third clamping block 192 is provided. The third clamping block 192 may include two, and the two third clamping blocks 192 are respectively located on both sides of the nut support seat 19.

[0158] Correspondingly, the mounting base 11 may be provided with a third plug hole 1147. The third plug holes 1147 include two, and the two third plug holes 1147 are respectively located on the inner walls of two opposite side panels of the mounting base 11.

[0159] The third clamping block 192 and the third jack 1147 are adapted to each other.

[0160] In this embodiment, by providing a matching third clamping block 192 and a third inserting hole 1147 , the nut support seat 19 is assembled on the bottom of the mounting base 11 to support the adjusting nut 18 .

[0161] In some embodiments, the third clamping block 192 may be provided with an inclined surface to help reduce resistance during the assembly process and effectively improve assembly efficiency and accuracy.

[0162] In an optional embodiment, as shown in FIG5 , the nut support seat 19 may further include a concave surface 191 and a first concave bayonet 193. The concave surface 191, with its opening facing upward, can be used to support the adjustment nut 18 and limit accidental vertical movement of the adjustment nut 18. Two first concave bayonet 193 may be included, one located on each side wall of the nut support seat 19.

[0163] Correspondingly, the arc-shaped sidewall 1141 defines a first blocking portion 1148 located on the inner surface of the arc-shaped sidewall 1141 .

[0164] The first recessed bayonet 193 and the first blocking portion 1148 are adapted to each other.

[0165] In this embodiment, a matching first recess and a first blocking portion 1148 are provided to effectively limit the position of the nut support seat 19 and correctly install the nut support seat 19, thereby avoiding mutual abutment between the nut and the adjusting nut 18 and causing wear of the adjusting nut 18, and further improving the overall structural stability of the rebounder.

[0166] The above embodiments have introduced the structure of the retaining portion 114 and its matching relationship. The following will introduce other components of the rebounder.

[0167] In an optional embodiment, as shown in FIG1 , the locking member 1 may further include a first cover plate 20, which may be provided with a first latching block and a second latching block 202. The first latching block may include two, one located on each side inner wall of the first cover plate 20 near the locking base 2. The second latching block 202 may include two, one located on each side inner wall of the first cover plate 20 away from the locking base 2.

[0168] Correspondingly, the mounting base 11 is further provided with a first socket 112 and a second socket 113. Two first sockets 112 may be provided, and the two first sockets 112 are respectively located on two opposing side panels of the mounting base 11 and close to the locking base 2. Two second sockets 113 may be provided, and the two second sockets 113 are respectively located on two opposing side panels of the mounting base 11 and away from the locking base 2.

[0169] The first card block is adapted to the first socket 112 , and the second card block 202 is adapted to the second socket 113 .

[0170] In this embodiment, by providing matching first latches and first insertion holes 112, second latches 202, and second insertion holes 113, the first cover plate 20 is removably assembled to the mounting base 11. Firstly, the first cover plate 20 protects the internal components of the rebounder, reducing corrosion and damage. Secondly, the first cover plate 20 can be quickly removed, facilitating adjustment of the rebounder and door gap size.

[0171] In an optional embodiment, as shown in FIG1 , the mounting base 11 further comprises a first assembly hole 115 and a second assembly hole 116 for screws to pass through. The first assembly hole 115 and the second assembly hole 116 are provided on the bottom plate of the mounting base 11 or on mounting wings 117 on both sides of the mounting base 11.

[0172] In this embodiment, the mounting base 11 can be mounted on the side panel in two ways: open mounting and concealed mounting. Concealed mounting is invisible, more aesthetically pleasing, and has good damage resistance. Open mounting is visible and more convenient to disassemble.

[0173] In an optional embodiment, as shown in FIG1 , the locking member 1 may further include a core barrel 12 for accommodating the core body. Wing-shaped protrusions 123 may be provided on either side of the core barrel 12, and a bottom plate 124 may be provided at the bottom of the core barrel 12. The gap between the wing-shaped protrusions 123 and the bottom plate 124 may form a guide groove 125.

[0174] Correspondingly, the mounting base is provided with a slide rail 111, which is located on the inner walls of two opposite side panels of the mounting base 11. The guide groove 125 is adapted to the slide rail 111.

[0175] In this embodiment, through the cooperation between the first guide groove 125 and the slide rail 111 , the core barrel 12 can slide in and out of the mounting base 11 , thereby achieving rapid assembly and disassembly.

[0176] In some embodiments, as shown in Figures 1 to 8, the core body may further include a sliding portion, wherein the sliding portion includes a clamping portion 13 facing the locking base 2, and the clamping portion 13 is provided with the claw 131. A slideway may be formed inside the core barrel 12 for the sliding portion to slide axially, thereby adjusting the degree of opening and closing of the claw 131.

[0177] In this embodiment, the sliding portion can slide axially into and out of the core barrel 12. When sliding into the core barrel 12, the claws 131 contract under the constraints of the inner wall of the core barrel 12. When sliding out of the core barrel 12, the claws 131 expand. The degree of opening and closing of the claws 131 can be effectively adjusted through the core barrel 12, thereby locking and releasing the locking base 2.

[0178] In some embodiments, the end of the sliding portion facing the locking base 2 may be further provided with two opposite through holes for allowing the two claws of the claw 131 to extend.

[0179] The following will introduce the structure of the sliding part and the matching relationship of the components.

[0180] In an optional embodiment, as shown in FIG. 7 , the sliding portion may include a first fixing portion 14 and a second fixing portion 15 .

[0181] One end of the first fixing portion 14 can extend out of the core barrel 12, and the other end is located in the core barrel 12. The second fixing portion 15 is located in the core barrel 12. The first ends of the first fixing portion 14 and the second fixing portion 15 are screwed together and their axial relative positions are adjustable.

[0182] In this embodiment, a first screw thread 141 may be provided on the inner side wall of the first fixing portion 14. Correspondingly, a second screw thread 151 may be provided on the outer side wall of the first end of the second fixing portion 15, wherein the first end of the second fixing portion 15 is the end of the second fixing portion 15 that is closer to the first fixing portion 14. The first screw thread 141 and the second screw thread 151 can be screwed together, connecting the first fixing portion 14 and the second fixing portion 15 together, and the relative position of the two can be adjusted by rotation. In actual application, the relative position of the first fixing portion 14 and the second fixing portion 15 can be adjusted by rotating the first fixing portion 14 in a predetermined clockwise direction, thereby precisely adjusting the door gap.

[0183] In this embodiment, the screw structure can provide a door gap adjustment range of ±2 mm. It should be noted that the screw structure can also be appropriately adjusted according to actual needs to provide different door gap adjustment ranges.

[0184] In the above embodiment, the first fixing portion 14 and the second fixing portion 15 are connected by a screw structure to achieve precise adjustment of the door gap. The following will provide an embodiment to illustrate how the holding portion 13 and the first fixing portion 14 are connected.

[0185] In some embodiments, the first fixing portion 14 may further be provided with a limiting block, which is located on the inner wall of the first fixing portion 14 . There may be two limiting blocks, which are positioned opposite to each other.

[0186] Correspondingly, as shown in Figures 6-8 , the clamping portion 13 may also be provided with at least two opposing, spaced-apart fixing claws 132. The fixing claws 132 are located at the end of the clamping portion facing away from the locking base 2. An inclined portion 1321 is provided on the outer side of the free end of the fixing claws 132, forming a recessed snap 1322 between the inclined portion 1321 and the clamping claws 131. The inclined portion 1321 is used to adjust the gap between the two fixing claws 132 so that the fixing claws 132 extend into the first fixing portion 14. The recessed snap 1322 is used to engage with the stop block for securement.

[0187] In this embodiment, the two fixing claws 132 of the holding portion 13 extend into the first fixing portion 14 until they are blocked by the limit block. At this time, the inclined portions 1321 of the two fixing claws 132 are against the limit block. Under the action of external force, the inclined portion 1321 will decompose the external force into a force in the vertical direction. The force in the vertical direction can squeeze the inclined portion 1321, thereby reducing the gap between the two fixing claws 132, so that the holding portion 13 can continue to extend into the first fixing portion 14. Finally: the concave bayonet 1322 and the shape of the limit block are adapted to fit together, so that the holding portion 13 and the first fixing portion 14 are engaged and connected. In this embodiment, there is no need to fix the holding portion 13 and the first fixing portion 14 with pins, which is simple to operate and effectively reduces costs.

[0188] In some embodiments, the stopper may have an inclined surface that cooperates with the inclined portion 1321 to more conveniently adjust the gap between the two fixing claws 132, thereby reducing operational difficulty. In some embodiments, the clamping portion 13 may be made of plastic, allowing the clamping portion 13 to automatically deform and recover due to the plastic's elasticity. It should be noted that the clamping portion 13 may also be made of other materials and connected to the first fixing portion 14 in other ways, depending on actual needs, and will not be elaborated here.

[0189] The above embodiment introduces the structure of the sliding portion and the matching relationship between the components. The structure and matching relationship of the other components of the rebounder will be introduced below.

[0190] In an optional embodiment, as shown in Figures 9 and 10, the second fixing portion 15 may also be provided with a semi-cylindrical arc surface 152 and a first flange 153. The semi-cylindrical arc surface 152 is formed by extending from the second end of the second fixing portion 15. The first flange 153 is located at the bottom of the semi-cylindrical arc surface 152. The core body may also include a hook portion 16 and a spring 17. The hook portion 16 may be provided with a hook 161 and a hook fixing seat 162. The hook 161 is fixed to the hook fixing seat 162. The hook fixing seat 162 is fixed to the end of the core barrel 12 away from the locking base 2. The spring 17 is supported between the hook fixing seat 162 and the first flange 153.

[0191] Among them, the inner wall of the semi-cylindrical arc surface 152 is also provided with a Y-shaped boss 1521, a hook introduction part and a hook exit part. The hook introduction part is used to guide the hook 161 to fall into the middle fork of the Y-shaped boss 1521, and the hook exit part is used to guide the hook 161 to detach from the Y-shaped boss 1521.

[0192] In this embodiment, under the action of the thrust, when the sliding portion compresses the spring 17 and slides to the first position, the hook 161 falls into the middle fork of the Y-shaped boss 1521 under the guidance of the hook introduction portion. After the thrust disappears, the hook 161 hooks the middle fork of the Y-shaped boss 1521, and the relative positions of the sliding portion and the core barrel 12 remain unchanged, thereby keeping the door panel in a tightly closed state or other desired state. At this time, the spring 17 remains in a compressed state. When the thrust is applied again, the sliding portion further compresses the spring 17 and slides to the second position, and the hook 161 disengages from the Y-shaped boss 1521 under the guidance of the hook outlet portion. When the thrust disappears again, based on the rebound force of the spring 17, the sliding portion slides out of the core barrel 12, and the claw 131 releases the locking base 2, thereby achieving the opening of the door panel.

[0193] The following is an exemplary introduction to the structure of the hook introduction part and the hook exit part and the matching relationship of the parts.

[0194] In some embodiments, as shown in Figures 9 and 10, the hook introduction portion may include a third passage 1522, a first inclined surface 1523 and a first U-shaped groove 1524. The third passage 1522, the first inclined surface 1523 and the first U-shaped groove 1524 are connected in sequence. The third passage 1522 is formed by the gap between the first side wall of the Y-shaped boss 1521 and the corresponding side edge of the semi-cylindrical arc surface 152, and is used for the hook 161 to slide to the first inclined surface 1523. The first inclined surface is used to guide the hook 161 to fall into the first U-shaped groove 1524. The first U-shaped groove 1524 is used to guide the hook 161 to fall into the middle fork of the Y-shaped boss.

[0195] The hook lead-out portion may include a second inclined surface 1525 . The second inclined surface 1525 is opposite to the middle fork of the Y-shaped boss 1521 and is used to guide the hook 161 to separate from the Y-shaped boss 1521 .

[0196] In this embodiment, when the sliding portion compresses the spring 17 and slides to the first position, the hook 161 sequentially passes through the third passage 1522, the first inclined surface 1523, and the first U-shaped groove 1524, and engages with the middle fork of the Y-shaped boss 1521, thereby maintaining the relative position of the sliding portion and the core barrel 12, and keeping the door panel locked. Under the action of an external force, when the sliding portion continues to compress the spring 17 and slides to the second position, the hook 161 disengages from the Y-shaped boss 1521 under the guidance of the second inclined surface 1525. When the external force disappears and the spring 17's rebound force is applied, the sliding portion slides out of the core barrel 12, and the claw 131 releases the locking base 2, thereby opening the door panel.

[0197] In some embodiments, the hook guide portion may further include a fourth passage 1527. This passage 1527 is formed by the gap between the second sidewall of the Y-shaped boss 1521 and the corresponding side edge of the semi-cylindrical curved surface 152, with the second sidewall positioned opposite the first sidewall. This passage 1527 allows the hook 161 to pass through. In some embodiments, the hook guide portion may further include a second U-shaped groove 1526 connected to the second inclined surface 1525. This groove 1526 is used to guide the hook 161 through the fourth passage 1527 and away from the semi-cylindrical curved surface 152.

[0198] The above embodiment describes how the sliding portion, the hook portion 16 and the spring 17 cooperate to maintain the door panel closed and open. The internal structure of the hook portion 16 and the relationship between the components will be described below as an example.

[0199] In an optional embodiment, as shown in Figure 11, the hook fixing seat 162 may include a fixing plate 1621 and a circular base 1622. The fixing plate 1621 and the circular base 1622 are perpendicular to each other and fixedly connected. The hook portion 16 also includes the threaded end 163, which is formed by extending from the end of the circular base 1622 away from the locking base 2. A deformable protrusion 1627 is provided at one end of the circular base 1622 facing the locking base 2. Correspondingly, a deformable recess 121 is provided at the end of the core barrel 12 away from the locking base 2. The deformable protrusion 1627 and the deformable recess 121 cooperate to engage and fix the core barrel 12 and the circular base 1622.

[0200] In this embodiment, the hook fixing seat 162 is fixed to the end of the core barrel 12 by the cooperation between the deformed protrusion 1627 and the deformed recess 121 .

[0201] In some embodiments, hook 161 may include a hook 1611 and a hook rod 1612. Hook 1611 and hook rod 1612 are fixedly connected. Part of the sidewall of hook rod 1612 is adjacent to fixing plate 1621. Fixing plate 1621 may be provided with a first protrusion 1624 and a second protrusion 1625. First protrusion 1624 and second protrusion 1625 are respectively provided on either side of hook rod 1612, and together, first protrusion 1624 and second protrusion 1625 are used to limit the swing range of hook rod 1612.

[0202] In this embodiment, the first protrusion 1624 and the second protrusion 1625 on both sides of the hook rod 1612 are used to jointly limit the swing range of the hook rod 1612, thereby avoiding the situation where the hook 1611 hooks the spring 17 due to excessive swinging of the hook rod, causing the elastic mechanism to be stuck and fail, and further optimizing the rebounder structure to make the rebounder structure more reasonable and stable.

[0203] In an optional embodiment, as shown in FIG11 , the hook fixing seat 162 may further include a second blocking portion 1623, which is formed by extending from the end of the circular base 1622 close to the fixing plate 1621. The second blocking portion 1623 is located above the hook rod 1612 and is used to limit the axial movement of the hook rod 1612.

[0204] In this embodiment, the second blocking portion 1623 is provided to limit the axial movement of the hook rod 1612, thereby avoiding the situation where the hook 1611 hooks the spring 17 due to the large axial movement range of the hook rod 1612, causing the elastic mechanism to be stuck and fail. The rebounder structure is further optimized, making the rebounder structure more reasonable and stable.

[0205] In an optional embodiment, as shown in Figures 1 to 11, the core barrel 12 is provided with a first pin hole 122, and the first pin hole 122 is located at the end of the core barrel 12 away from the locking base 2. The free end of the hook 161 is provided with a ring to form a round hole 1613. The second blocking portion 1623 is provided with an arc hole 1628. A second pin hole 1626 is provided on the fixing plate. Among them, the first pin hole 122, the arc hole 1628, the round hole 1613 and the second pin hole 1626 are positioned correspondingly, and the shaft pin 164 passes through the first pin hole 122, the arc hole 1628, the round hole 1613 and the second pin hole 1626 in sequence to bridge the two sides of the core barrel 12, so that the hook portion 16 is fixedly connected to the core barrel 12.

[0206] In this embodiment, the hook portion 16 is fixed in the core barrel 12 by the shaft pin 164, which can further improve the structural stability of the rebounder.

[0207] It should be noted that other methods can also be used to fixedly connect the hook portion 16 to the core barrel 12, which can be selected according to actual needs and is not limited here.

[0208] In actual applications, the installation position of the locking member 1 or the locking base 2 may deviate from the predetermined position, which may cause the locking base 2 to be misaligned with the locking member 1 when closing the door, thereby causing the door to fail to lock. To reduce the possibility of door locking failure, some exemplary embodiments are provided below.

[0209] In an optional embodiment, as shown in FIGS. 12 and 13 , the locking base 2 may include a base body 21 and a rotating column 23 .

[0210] As shown in Figures 12-13, the base body 21 may be provided with a fixing hole 213, the inner wall of which is provided with a snap ring 2131. Correspondingly, the rotating column 23 may include a clamping end 231 and a flange end 232. The clamping end 231 is configured to removably engage with the claw 131. The flange end 232 may include a second flange 2321, a third flange 2322, and a second circumferential groove 2323 located between the second and third flanges 2321, 2322.

[0211] The snap ring 2131 and the second circumferential groove 2323 engage to confine the rotating column 23 to the base body 21. The diameter of the second circumferential groove 2323 is smaller than the inner diameter of the snap ring 2131, and the third flange 2322 is larger than the inner diameter of the snap ring 2131. The third flange 2322 is movably confined between the snap ring 2131 and the door panel.

[0212] In this embodiment, the rotating column 23 can rotate and swing 360 degrees circumferentially within the retaining ring 2131, allowing the rotating column 23 to fine-tune its angle to align with the latch 131, thereby reducing the possibility of door locking failure. This process does not require the use of external tools to adjust the position of the locking base 2 or the locking member 1, thereby improving the practicality and convenience of the rebound device.

[0213] In some embodiments, the base body 21 may further include a third assembly hole 211 and a fourth assembly hole 212. The third assembly hole 211 and the fourth assembly hole 212 can be threaded with screws. The installer can secure the locking base 2 to the door panel using screws. Alternatively, welding or other methods can be used to secure the locking base 2 to the door panel. This method is not limited to the above and is selected based on actual needs.

[0214] In some embodiments, the locking base 2 may further include a second cover plate 22, which may be placed on the third assembly hole 211 and the fourth assembly hole 212. In the assembled state, the second cover plate 22 may protect the screws from corrosion by moisture and other substances in the air, thereby improving the durability and aesthetics of the locking member.
