When the semi-trailer head and the semi-trailer carriage are connected, the clamping inlet 3 and the matching opening 15 move towards the traction pin 1, and after the traction pin 1 enters the clamping inlet 3 and the matching opening 15, the first self-locking piece 6 and the second self-locking piece 7 are close to each other until the first locking groove 8 of the last first self-locking piece 6 and the second locking groove 9 of the second self-locking piece 7 are abutted against the outer side of the traction pin 1, and meanwhile, the first self-locking piece 6 and the second self-locking piece 7 mutually achieve position termination through the first yielding groove 10 and the second yielding groove 11, so that the connection of the traction seat 2 and the traction pin 1 is achieved, and the first self-locking piece 6 and the second self-locking piece 7 can be stably connected with the traction pin 1 in the use process, so that the connection stability is guaranteed.
First, the state before the car is connected to the head is:
The locking tooth 31 is in a state of meshing with the synchronizing gear 27 (the third elastic member 30 is in the longest length state), and the middle portion of the locking member 29 is located in the card inlet 3; the operating ring 34 is in a separated state from the hanging groove 33; the unlocking arm 38 abuts against the inner end of the bottom hole 37 (the fourth elastic member 40 is in the longest length state); the first self-locking piece 6 and the second self-locking piece 7 are in the outermost state, and the traction pin 1 enters between the first self-locking piece and the second self-locking piece; the coupling wheel 36 is located on the side of the mating opening 15 (the towing pin 1 can move directly past the coupling wheel 36);
Then, in the process of moving the traction seat 2 towards the traction pin 1, firstly, the middle part of the traction pin 1 acts on the outer side of the linkage wheel 36 to drive the linkage wheel 36, the matching rod 35, the unlocking arm 38 and the unlocking piece 39 to move outwards, but other structures are not influenced (the middle part of the traction pin 1 has smaller diameter, and the middle part can better drive the linkage wheel 36 and the matching rod 35 to move when acting on the outer wall of the linkage wheel 36);
When the traction seat 2 passes between the first self-locking piece 6 and the second self-locking piece 7 and continuously acts on the middle part of the locking piece 29 forwards, the locking piece 29 is driven to move towards the outside of the stop seat 12 until the locking teeth 31 are separated from the synchronous gear 27 (wherein the two outer sides, the top and the bottom of the locking piece 29 are attached to the inner wall of the middle groove 28, so that the movement stability of the locking piece 29 is ensured); at this time, under the elastic action of the first elastic element 20 and the second elastic element 22, the first self-locking element 6 and the second self-locking element 7 are automatically close to each other, and at the end of the last first self-locking element 6 is abutted against the end of the second abdication groove 11, and the end of the second self-locking element 7 is abutted against the end of the first abdication groove 10 (at this time, the first elastic element 20 and the second elastic element 22 are still in a compressed state), so that the connection between the traction pin 1 and the traction seat 2 is completed; the traction pin 1 is not in complete close contact with the first self-locking member 6 and the second self-locking member 7 in actual use, but the first elastic member 20 and the second elastic member 22 are in a compressed state, so that the first elastic member 20 and the second elastic member 22 can be continuously applied to the action of the first self-locking member 6 and the second self-locking member 7 which are close to each other in the use process, and the traction pin 1 can always be under the action of the first self-locking member 6 and the second self-locking member 7 and is stably connected with the traction seat 2;
Meanwhile, the first locking groove 8 and the second locking groove 9 act on the traction pin 1 in a plane shape, so that horizontal acting force is not generated; secondly, even if relative rotation occurs between the traction seat 2 and the traction pin 1, for example, the traction pin 1 applies an outward force to the first self-locking piece 6 at the moment, and the traction pin 1 also applies an inward force to the second self-locking piece 7 at the moment; when the first self-locking member 6 has an outward acting force, the first linkage arm 25 can act on the synchronous gear 27, so that the synchronous gear 27 has a counterclockwise rotation tendency; after the second linkage arm 26 acts on the synchronous gear 27, the synchronous gear 27 has a clockwise rotation trend, so that the synchronous gear 27 can prevent the first linkage arm 25 and the second linkage arm 26 from moving, and the first self-locking piece 6 and the second self-locking piece 7 cannot move, so that the first self-locking piece 6 and the second self-locking piece 7 generate an interlocking effect through the synchronous gear 27, the first linkage arm 25 and the second linkage arm 26, and the connection stability between the traction pin 1 and the traction seat 2 is ensured.
When separating the towing pin 1 and the towing seat 2, firstly keeping the two mutually static, then a worker pulls the unlocking rod 24 outwards through the operating ring 34 and buckles the operating ring 34 in the hanging groove 33 (at the moment, the space between the first self-locking piece 6 and the second self-locking piece 7 is used for the towing pin 1 to pass through); in the process of pulling the operation ring 34, the first self-locking piece 6 drives the first linkage arm 25 to move, the first linkage arm 25 drives the synchronous gear 27 to rotate, and the synchronous gear 27 can drive the second self-locking piece 7 to move outwards through the second linkage arm 26; meanwhile, when the operating ring 34 is hung in the hanging groove 33, the projection of the locking tooth 31 outside the termination seat 12 is meshed with the projection of the synchronous gear 27 outside the termination seat 12; thus, when the traction pin 1 moves towards the direction outside the card inlet 3, first the third elastic member 30 acts on the locking member 29 and drives the locking member 29 to move towards the card inlet 3; until a certain time point, the locking teeth 31 are meshed with two sides of the synchronous gear 27, so that the synchronous gear 27 cannot rotate at the moment, and the positions of the first self-locking piece 6 and the second self-locking piece 7 are fixed;
The traction pin 1 then continues to move outwards of the card inlet 3 until it acts on the inside of the coupling wheel 36, at which point the traction pin 1 drives the engagement rod 35 through the coupling wheel 36 towards the direction of entry into the horizontal hole, simultaneously also drives the unlocking arm 38 and the unlocking piece 39 to move, and then at a certain point the inclined portion of the underside of the end of the unlocking piece 39 acts on the inside of the top of the operating ring 34 and drives the operating ring 34 to disengage from the hanging groove 33; the operating ring 34 or the hanging seat 32 is made of a material with a certain elasticity, so that after the operating ring 34 is hung on the hanging seat 32, the position of the operating ring 34 can be ensured, but at the same time, when the operating ring 34 is pressed down by the unlocking piece 39, the operating ring 34 can be separated from the hanging seat 32.
After the operating ring 34 is separated from the hanging seat 32, at this time, the synchronizing gear 27 is acted by the locking teeth 31, so that even if the first elastic member 20 and the second elastic member 22 have elastic acting forces, the first self-locking member 6 and the second self-locking member 7 can only be kept at the original positions, and wait for the next automatic locking of the traction pin 1. When the traction pin 1 passes through the linkage wheel 36, the linkage wheel 36 moves to the initial position under the elastic force of the fourth elastic member 40, and waits for the next action with the traction pin 1.
In the whole connecting process of the traction pin 1 and the traction seat 2, stable connection of the traction pin 1 and the traction seat 2 can be realized without any operation when the traction pin and the traction seat are connected; when the two are separated, the operation ring 34 is simply and conveniently hung on the hanging seat 32 after the operation ring 34 is pulled outwards.
In still another embodiment, there is no structure of the engaging lever 35, the coupling wheel 36, the unlocking piece 39, etc., but there is a structure of the hanging seat 32, etc., so that it is necessary to pull the operating ring 34 to hang in the hanging groove 33 when separating the positioning pin 1 and the positioning seat 2, then manually separate the operating ring 34 from the hanging seat 32 when separating the traction pin 1 and the traction seat 2, and then wait for the next automatic connection of the traction pin 1 and the traction seat.
The above description is only illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the present invention, and any alterations and modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the appended claims.
