[0024] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0025] The adapter for a stable trailer connection includes a connecting main rod 2, a first disconnecting module 1, and a second disconnecting module 3. The connecting main rod 2 is used to assemble with the trailer body 4, and its two ends are respectively assembled with the first connecting module 1 and the second disconnecting module 3. The first disconnecting module 1 includes a first horizontal locking rod 11, a first main clamping plate 12, a first auxiliary clamping plate 13, and a first clamping structure 14. The first horizontal locking rod 11 passes through the end of the connecting main rod 2 and is arranged to lock or unlock with the connecting main rod 2. The end of the first horizontal locking rod 11 is assembled with the first main clamping plate 12. The first clamping structure 14 is assembled with the first main clamping plate 12 and the first auxiliary clamping plate 13, and the first clamping structure 14 is used to apply clamping force between the first main clamping plate 12 and the first auxiliary clamping plate 13. The first main clamping plate 12 and the first auxiliary clamping plate 13 are used to clamp the vehicle.

[0026] The aforementioned adaptable and stable trailer connection device, when not in use or when switching vehicles, can be separated from the vehicle by removing the clamping force between the first main clamping plate 12 and the first auxiliary clamping plate 13, and the locking force of the first clamping structure 14, through the separate operation of the first horizontal locking bar 11 and the first clamping structure 14. The operation is simple, quick, and portable. During assembly, the trailer body 4 is assembled with the vehicle by the first disassembly module 1 and the second disassembly module 3, respectively. Under the clamping action of the first main clamping plate 12 and the first auxiliary clamping plate 13, and the locking action of the first clamping structure 14, the assembly stability with the vehicle is enhanced, avoiding shaking or loosening, and ensuring safety. Furthermore, the distance between the first disassembly module 1 and the second disassembly module 3 can be adjusted by the first horizontal locking bar 11 to accommodate different vehicle specifications and improve the adaptability of the trailer connection device.

[0027] The first clamping structure 14 includes two first clamping shafts 141 and two first clamping levers 142. The two first clamping shafts 141 and the two first clamping levers 142 are arranged in a one-to-one assembly. The first clamping shafts 141 simultaneously pass through the first main clamping plate 12 and the first auxiliary clamping plate 13, and the first clamping shafts 141 and the first auxiliary clamping plate 13 are threadedly connected. The rotation of the first clamping shafts 141 is used to adjust the distance between the first auxiliary clamping plate 13 and the first main clamping plate 12.

[0028] In this way, with the cooperation of the two first clamping shafts 141 and the two first clamping levers 142, the distance between the first auxiliary clamping plate 13 and the first main clamping plate 12 can be adjusted, thereby clamping the vehicle; at the same time, the switching between disassembly and locking can be achieved by moving or rotating the first clamping levers 142.

[0029] The first clamping lever 142 includes a first lever body and a first adapter post. The inner end of the first clamping shaft 141 passes through the first adapter post, and the first clamping shaft 141 and the first adapter post are arranged perpendicularly. The first lever body and the first adapter post are arranged movably. The first lever body is oscillating relative to the first adapter post under the influence of a levering force. The first lever body is used for the user to hold and apply force.

[0030] In this way, the first lever body facilitates the user's operation in assembling and disassembling the trailer connection device.

[0031] The first clamping structure 14 includes two first axis limiting shells 143. The first axis limiting shells 143 are installed on the first main clamping plate 12. The two first axis limiting shells 143 are arranged in a one-to-one correspondence with the two first clamping shafts 141, and the first clamping shafts 141 pass through the first axis limiting shells 143. The first axis limiting shells 143 are arranged in a mating arrangement with the first lever body, and the first axis limiting shells 143 are used to restrict the first lever body from continuing to move toward the first main clamping plate 12.

[0032] In this way, the rotation range of the first lever body is limited by the first axis limiting housing 143, which avoids the first lever body from moving too much and facilitates the switching between disassembly and assembly.

[0033] The first disassembly module 1 includes two first shaft posts 16. The inner end of the first shaft post 16 is arranged to be mated with the first main clamping plate 12. The outer end of the first shaft post 16 extends vertically in a direction away from the first main clamping plate 12. Two first clamping shafts 141 and two first shaft posts 16 are arranged in a one-to-one correspondence. The first clamping shafts 141 pass through the first shaft posts 16 and are threadedly connected to the first shaft posts 16.

[0034] Under the action of the first shaft fixing column 16, the setting of the first clamping shaft 141 plays a positioning and reinforcement role, thereby effectively preventing the first clamping shaft 141 from shifting, making it easier for the first clamping shaft 141 to keep straight, thus facilitating the cooperation between the first clamping shaft 141 and the first main clamping plate 12 and the first auxiliary clamping plate 13.

[0035] The end of the connecting main rod 2 forms a rod fixing head, the first horizontal locking rod 11 passes through the rod fixing head, the first disassembly module 1 includes two rod nuts, the two rod nuts are respectively fitted with the first horizontal locking rod 11 and are threadedly connected, the rod fixing head is located between the two rod nuts, and the two rod nuts are respectively arranged in abutment with the rod fixing head.

[0036] In this way, the assembly stability of the first horizontal locking rod 11 and the rod fixing head is improved by the action of the two rod nuts, and the setting stability of the first horizontal locking rod 11 is also improved.

[0037] The first disassembly module 1 includes a first guide rod 15, which is mated and fixedly arranged with the first main clamping plate 12. The first guide rod 15 extends protrudingly in a direction away from the first main clamping plate 12. The first horizontal locking rod 11 passes through the first guide rod 15 and is threadedly connected to the first guide rod 15.

[0038] Under the action of the first guide rod 15, the setting of the first horizontal locking rod 11 is strengthened and guided, thereby improving the stability of the setting of the first horizontal locking rod 11.

[0039] The first guide rod 15 is arranged in a frustum shape, and its cross-sectional area gradually decreases along the direction away from the first main clamping plate 12, thereby improving the stability of the first horizontal locking rod 11.

[0040] The connecting main rod 2 includes a horizontal main rod 22 and two side main rods 21. The horizontal main rod 22 is used to assemble with the trailer body 4. The two ends of the horizontal main rod 22 are respectively connected to the two side main rods 21 and are integrally formed. Along the direction opposite to the horizontal main rod 22, the two side main rods 21 are arranged in opposite directions, and the outer end of the side main rods 21 forms a rod fixing head.

[0041] The first main clamping plate 12 includes a first main body and two first side fixing plates. The two sides of the first main body are respectively connected to the two first side fixing plates and are integrally formed. The first side fixing plates extend towards the first auxiliary clamping plate 13, and the two first side fixing plates are used to abut against the vehicle. In this way, the stability of the first main clamping plate 12 in conjunction with the vehicle is improved, avoiding shaking, sliding and other situations, and improving the safety of use.

[0042] The first clamping plate 13 has a textured area with multiple stripes. The textured area is used to increase friction resistance. During assembly, the textured area is laid flat against the vehicle. This improves the stability of the first clamping plate 13 in relation to the vehicle, avoids shaking or slipping, and improves safety in use.

[0043] The second disassembly module 3 includes a second horizontal locking rod, a second main clamping plate, a second auxiliary clamping plate, and a second clamping structure. The second horizontal locking rod passes through the end of the connecting main rod 2 and is arranged to be locked or unlocked with the connecting main rod 2. The end of the second horizontal locking rod is assembled with the second main clamping plate. The second clamping structure is assembled with the second main clamping plate and the second auxiliary clamping plate respectively. The second clamping structure is used to apply clamping force between the second main clamping plate and the second auxiliary clamping plate. The second main clamping plate and the second auxiliary clamping plate are used to clamp the vehicle.

[0044] The second clamping structure includes two second clamping shafts and two second clamping levers. The two second clamping shafts and two second clamping levers are assembled one by one. The second clamping shafts pass through the second main clamping plate and the second auxiliary clamping plate simultaneously, and the second clamping shafts are threadedly connected to the second auxiliary clamping plate. The rotation of the second clamping shafts is used to adjust the distance between the second auxiliary clamping plate and the second main clamping plate.

[0045] In this way, with the combined action of the two second clamping shafts and the two second clamping levers, the distance between the second auxiliary clamping plate and the second main clamping plate can be adjusted, thereby clamping the vehicle; at the same time, the disassembly and locking can be switched by moving or rotating the second clamping levers.

[0046] The second clamping lever includes a second lever body and a second adapter post. The inner end of the second clamping shaft passes through the second adapter post, and the second clamping shaft and the second adapter post are arranged perpendicularly. The second lever body and the second adapter post are arranged movably. The second lever body is oscillating relative to the second adapter post under the influence of the lever force. The second lever body is used for the user to hold and apply force.

[0047] In this way, the second lever body facilitates the user's operation in assembling and disassembling the trailer connection device.

[0048] The second clamping structure includes two second axis limiting shells, which are installed on the second main clamping plate. The two second axis limiting shells are arranged in a one-to-one correspondence with the two second clamping shafts, and the second clamping shafts pass through the second axis limiting shells. The second axis limiting shells are arranged in a mating arrangement with the second lever body, and the second axis limiting shells are used to restrict the second lever body from continuing to move toward the second main clamping plate.

[0049] In this way, the rotation range of the second lever body is limited by the second axis limiting housing, which avoids excessive movement of the second lever body and facilitates switching between disassembly and assembly.

[0050] The second disassembly module 3 includes two second shaft posts. The inner end of the second shaft post is arranged to be aligned with the second main clamping plate. The outer end of the second shaft post extends vertically in a direction away from the second main clamping plate. The two second clamping shafts and the two second shaft posts are arranged in a one-to-one correspondence. The second clamping shafts pass through the second shaft posts and are threadedly connected to the second shaft posts.

[0051] Under the action of the second shaft fixing column, the setting of the second clamping shaft plays a positioning and reinforcement role, thereby effectively preventing the second clamping shaft from shifting, making it easier for the second clamping shaft to keep straight, and thus facilitating the cooperation between the second clamping shaft and the second main clamping plate and the second auxiliary clamping plate.

[0052] The end of the connecting main rod 2 forms a rod fixing head, the second horizontal locking rod passes through the rod fixing head, the second disassembly module 3 includes two rod nuts, the two rod nuts are respectively fitted with the second horizontal locking rod and are threadedly connected, the rod fixing head is located between the two rod nuts, and the two rod nuts are respectively arranged in abutment with the rod fixing head.

[0053] In this way, the assembly stability of the second horizontal locking rod and the rod fixing head is improved by the action of the two rod nuts, and the setting stability of the second horizontal locking rod is also improved.

[0054] The second disassembly module 3 includes a second guide rod, which is mated and fixedly arranged with the second main clamping plate. The second guide rod extends protrudingly in a direction away from the second main clamping plate. The second horizontal locking rod passes through the second guide rod and is threadedly connected to the second guide rod.

[0055] The second guide rod enhances the reinforcement and guidance of the second horizontal locking rod, thereby improving its stability.

[0056] The second guide rod is arranged in a frustum shape, and its cross-sectional area gradually decreases along the direction away from the second main clamping plate; this improves the stability of the second horizontal locking rod.

[0057] The second main clamping plate includes a second main body and two second side plates. The two sides of the second main body are respectively connected to the two second side plates and are integrally formed. The second side plates extend towards the second auxiliary clamping plate and are used to abut against the vehicle. This improves the stability of the second main clamping plate and the vehicle, avoids shaking or sliding, and improves the safety of use.

[0058] The second clamping plate has a textured area with multiple stripes. The textured area is used to increase friction resistance. During assembly, the textured area is laid flat against the vehicle. This improves the stability of the second clamping plate in relation to the vehicle, avoids shaking or slipping, and improves safety.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
