Description

Technical Field

[0001] This utility model relates to the field of traction connector technology, specifically a traction connector that facilitates limiting connection. Background Technology

[0002] A traction connector is a mechanical device used to transfer traction force (such as from trailers, cranes, vehicles, etc.) to the towed object (such as carriages, ships, cargo, etc.). It is commonly used in various traction systems to ensure a secure connection between the traction device and the towed object, and to bear and transmit forces during traction. However, existing traction connectors still have certain shortcomings in use, such as…

[0003] Existing towing connectors mostly require the trailer to be moved slowly and continuously during connection to align the two holes on the connector and the trailer, and then connect them with a pin. The connection is slow, and the connector and trailer of existing towing connectors usually do not have a rotating structure. When traveling on bumpy roads, the towing connector is subjected to greater stress and greater wear on the structure. Utility Model Content

[0004] The purpose of this utility model is to provide a traction connector that facilitates limiting connection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a traction connector that facilitates limiting connection, comprising: a trailer frame, a connecting mechanism, a U-shaped component, and a mounting plate;

[0006] A connecting mechanism is provided on one side of the trailer, a U-shaped part is provided on one side of the connecting mechanism, a mounting plate is abutted on one side of the U-shaped part, and a rotating mechanism is provided between the trailer and the connecting mechanism.

[0007] The connecting mechanism includes: a hook, a column, a fixing pin, a storage slot, a limiting block, an anti-detachment block, and a spring. The hook is rotatably connected inside the tow rack, and the column abuts inside the hook. The column is fixedly connected to the inner wall of the U-shaped part. The fixing pin slides through the hook and is located on one side of the column.

[0008] Preferably, the fixing pin has a storage groove inside, and two sets of limiting blocks are slidably connected in the storage groove, with both sets of limiting blocks abutting against the front of the hook.

[0009] Preferably, both the front and rear parts of the two sets of limiting blocks are connected to anti-detachment blocks, which are slidably connected to the inner wall of the storage groove.

[0010] Preferably, a spring is connected between the two sets of limiting blocks, and the spring is disposed in the receiving groove.

[0011] Preferably, the rotating mechanism includes: a first limiting groove, a first positioning hole, a first positioning bolt, a T-shaped shaft, a second limiting groove, a second positioning hole, a second positioning hole and a second positioning bolt, and the upper surface of the hook is provided with the first limiting groove.

[0012] Preferably, the upper surface of the trailer is provided with a first positioning hole, a first positioning bolt is threaded into the first positioning hole, and the end of the first positioning bolt is disposed in a first limiting groove.

[0013] Preferably, a T-shaped shaft is rotatably connected through the mounting plate, and the T-shaped shaft is connected to one side of the U-shaped component.

[0014] Preferably, a second limiting groove is provided on one side of the T-shaped shaft, and a second positioning hole is provided on the side of the mounting plate away from the U-shaped part. A second positioning bolt is threaded into the second positioning hole, and the second positioning bolt slides through the second limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This traction connector, which facilitates limiting connection, is hung on the column by rotating the hook, and then the fixing pin is inserted into the hook. The limiting block extends from the receiving groove and abuts against the inner wall of the hook, thus facilitating the limiting connection of the traction connector. By rotating and fixing the first positioning bolt in the first positioning hole, and then rotating and fixing the second positioning bolt through the second limiting groove in the second positioning hole, the tow frame and the mounting plate can rotate relative to each other at a certain angle, thereby dispersing the stress of the traction connector. The specific details are as follows:

[0016] 1. By rotating the hook, the hook is hung on the column. Then, the fixing pin is inserted into the hook. After the limiting block extends out of the hook, the limiting block extends out of the storage groove and abuts against the inner wall of the hook to prevent the fixing pin from falling out of the hook, thereby making the traction connector easy to limit the connection.

[0017] 2. By installing the first positioning bolt in the first positioning hole, extending the end of the first positioning bolt into the first limiting groove, and then installing the second positioning bolt through the second limiting groove into the second positioning hole, the trailer and the mounting plate can rotate relative to each other at a certain angle during the traction process, thereby allowing the traction connector to distribute stress.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution: a traction connector for easy limiting connection, comprising: a tow frame 1, a connecting mechanism 2, a U-shaped component 3, and a mounting plate 4; the connecting mechanism 2 is provided on one side of the tow frame 1, the U-shaped component 3 is provided on one side of the connecting mechanism 2, and the mounting plate 4 is abutted on one side of the U-shaped component 3; a rotating mechanism 5 is provided between the tow frame 1 and the connecting mechanism 2; the connecting mechanism 2 includes: a hook 201, a column 202, a fixing pin 203, a storage groove 204, a limiting block 205, an anti-detachment block 206, and a spring 207; the hook 201 is rotatably connected inside the tow frame 1, and the column 202 abuts against the column 4 inside the hook 201. The column 202 is fixedly connected to the inner wall of the U-shaped part 3. A fixing pin 203 slides through the hook 201. The fixing pin 203 is located on one side of the column 202. A storage groove 204 is opened inside the fixing pin 203. Two sets of limiting blocks 205 are slidably connected in the storage groove 204. Both sets of limiting blocks 205 abut against the front of the hook 201. Anti-detachment blocks 206 are connected to the front and rear of the two sets of limiting blocks 205. The anti-detachment blocks 206 are slidably connected to the inner wall of the storage groove 204. A spring 207 is connected between the two sets of limiting blocks 205. The spring 207 is located in the storage groove 204.

[0027] In practice, the hook 201 is rotated and inserted into the U-shaped part 3 and hung on the column 202. Then, the fixing pin 203 is inserted into the hook 201, and the inner wall of the hook 201 presses the limiting block 205. The limiting block 205 is retracted into the storage groove 204 and the spring 207 is compressed. After the limiting block 205 extends out of the hook 201, the spring 207 pushes the limiting block 205 out of the storage groove 204, so that the traction connector can be easily limited and connected.

[0028] See Figures 1-3 , Figure 5 and Figure 6 It is known that the rotating mechanism 5 includes: a first limiting groove 501, a first positioning hole 502, a first positioning bolt 503, a T-shaped shaft 504, a second limiting groove 505, a second positioning hole 506, a second positioning hole 506, and a second positioning bolt 507.

Then, the second positioning bolt 507 is inserted into the second positioning hole 506 through the second limiting groove 505 and rotated to fix the second positioning bolt 507 into the second positioning hole 506 to limit the rotation angle of the U-shaped part 3 and the T-shaped shaft 504. During the traction process, the towing frame 1 and the mounting plate 4 can rotate relative to each other at a certain angle to disperse the stress of the traction connector.

[0030] In summary: When using this traction connector that facilitates limiting connection, firstly, the trailer 1 and mounting plate 4 are installed with the traction equipment and the equipment to be traction, respectively. Then, the hook 201 is rotated and hung on the column 202, and the fixing pin 203 is inserted into the hook 201 for fixation.
