The projection 310 moves forward to press against the blocking surface 61 so that the damping member 20 moves forward until the second pin 02 slides into the first chute 122 and the second pin 02 stops at a position where the first rotating member 60 avoids the projection 310, and the projection 310 continues to move forward to press against the pressing end 721 so that the third pin 03 moves away from the projection 310 and stops at a position where the second rotating member 70 avoids the projection 310; the protrusion 310 moves backward to press the toggle 50, so that the damping member 20 moves backward and the second pin 02 slides into the guide slot 121, and the pressing end 721 extends out of the base 10; when the second pin 02 is located in the guide groove 121, the protrusion 310 moves backward to press the reset portion 722 so that the third pin 03 is away from the protrusion 310 until the protrusion 310 passes over the second rotating member 70 and the first rotating member 60, and the blocking surface 61 and the pressing end 721 extend out of the base 10 under the action of the first torsion spring 04 and the second torsion spring 05.

In this embodiment, when the second pin 02 is located in the guide groove 121 and the first torsion spring 04 and the second torsion spring 05 are not subjected to an external force, a space suitable for accommodating the protrusion 310 is formed between the blocking surface 61 and the toggle surface 51. When the door 200 is in the fully opened state, the protrusion 310 is not located in the space between the blocking surface 61 and the toggle surface 51.

The damper is in a normal state, that is, if the door body 200 is in a fully opened state, the third pin 03 is far away from the protrusion 310 and stops at a position where the second rotating member 70 avoids the protrusion 310, the second pin 02 is located at one end of the first chute 122 far away from the protrusion 310, and the first rotating member 60 avoids the protrusion 310; the damper is in a failure state, which means that the second pin 02 is located in the guide groove 121 if the door body 200 is in a fully opened state.

The assembly process is as follows:

firstly, the damping piece 20 is placed into the sliding groove 12 from an opening of the groove bottom of the sliding groove 12 of the base 10, the fixture blocks 213 on two sides of the damping piece 20 are respectively placed into the guide grooves 121 on two sides of the base 10, the extension part 22 of the damping piece 20 is close to the groove bottom of the mounting groove 11, then the buffer piece 30 is placed into the mounting groove 11 from the opening of the mounting groove 11, the output end of the buffer piece 30 extends into the sliding groove 12, and the output end of the buffer piece 30 is fixedly connected with the rear end of the extension part 22 of the damping piece 20; then, the first rotating member 60, the second rotating member 70 and the second torsion spring 05 are connected together through the third pin 03, and then connected together with the toggle member 50 and the first torsion spring 04 to form a rotating assembly, the rotating assembly is placed into the through groove 21 from the opening of the through groove 21 of the damping member 20 close to the projection 310 until the first supporting surface 52 or the second supporting surface 53 of the toggle member 50 abuts against the end surface of the groove wall of the sliding groove 12, then the first pin 01 passes through the transverse groove 211 and the guide groove 121, and the second pin 02 passes through the second inclined groove 212 and the guide groove 121, wherein the middle part of the first pin 01 and the toggle member 50 form an interference fit, and the middle part of the second pin 02 and the toggle member 50 form an interference fit, so that the first pin 01 and the second pin 02 are prevented from moving along the axial direction thereof. The two ends of the elastic member 40 are fixed with respect to the rear end of the base 10 and the front end of the extension 22, respectively.

It can be seen that the damper of the present invention is easy to disassemble and assemble, and the positioning of the latch 213 facilitates the positioning of the damping member 20, thereby facilitating the installation of the toggle member 50, the first rotating member 60, the first pin 01 and the second pin 02.

The working principle is as follows:

when the door body 200 is in the fully opened state, if the damper is in the normal state at this time, the third pin 03 is away from the protrusion 310 and stops at the position where the pressing end 721 of the second rotating member 70 avoids the protrusion 310, referring to fig. 9, the second pin 02 is located at the end of the first chute 122 away from the protrusion 310 so as to drive the blocking surface 61 of the first rotating member 60 to enter the chute 12 and avoid the protrusion 310, that is, the first rotating member 60 and the second rotating member 70 both avoid the protrusion 310; when the door body 200 moves in the door closing direction in the fully opened state, that is, moves backwards, the protrusion 310 may directly pass over the first rotating member 60 and the second rotating member 70 until the protrusion surface 51 of the toggle member 50 is pressed, when the door body 200 moves backwards, the protrusion surface 51 is pressed to drive the toggle member 50 to move backwards, when the toggle member 50 moves backwards, the first pin 01 and the second pin 02 are driven to move backwards, so as to drive the damping member 20 to move backwards and enable the second pin 02 to slide into the guide groove 121, as the second pin 02 slides into the guide groove 121, the first torsion spring 04 acts on the first rotating member 60 and enables the blocking surface 61 to extend out of the base 10, and drives the third pin 03 to move towards the direction close to the protrusion 310, and the reset portion 722 and the pressing end 721 extend out of the base 10 under the action of the second torsion spring 05; as the lug 310 continues to move backwards, the lug 310 continues to press against the dial surface 51 to drive the dial piece 50, the first rotating piece 60 and the second rotating piece 70 to move backwards and also drive the damping piece 20 to move backwards, resistance applied by the damping piece 20 buffers door closing, and meanwhile, the elastic piece 40 releases energy to push the damping piece 20 to move backwards, so that the door is closed easily and slowly;

if the damper is in a failure state, the second pin 02 is located in the guiding groove 121, as mentioned above, the reset portion 722, the abutting end 721 and the blocking surface 61 all extend out of the base 10, as shown in fig. 10, when the door body 200 moves from the fully opened state in the door closing direction, i.e. moves backwards, the damper does not act on the protrusion 310 until the protrusion 310 acts on the reset portion 722, and before the protrusion 310 does not act on the reset portion 722, the protrusion 310 does not receive the buffering force, so that the buffering door closing cannot be achieved, in this embodiment, the protrusion 310 moves backwards to press the reset portion 722 to make the third pin 03 away from the protrusion 310 until the protrusion 310 passes over the second rotating member 70 and the first rotating member 60, specifically, as shown in fig. 11, the protrusion 310 presses the reset portion 722 first, and makes the first abutting surface 723 approach the second abutting surface 63, and as the protrusion 310 continues to move backwards, as shown in fig. 12, the bump 310 presses against the reset portion 722 and the third pressing surface 62 at the same time, so that the first pressing surface 723 presses against the second pressing surface 63, and the third pin 03 is driven to move away from the bump 310, so that the bump 310 can pass through the second rotating member 70 and the first rotating member 60, specifically, the blocking surface 61 of the first rotating member 60 enters the chute 12 under the combined action of the second rotating member 70 and the bump 310, so that the bump 310 can pass through the first rotating member 60, the pressing end 721 of the second rotating member 70 forms a short interval with the bump 310 under the action of the bump 310, so that the bump 310 can pass through the second rotating member 70, as shown in fig. 13, the bump 310 moves into the space between the blocking surface 61 and the toggle surface 51, as described above, the blocking surface 61 and the pressing end 721 extend out of the base 10 under the action of the first torsion spring 04 and the second torsion spring 05, and the damper can act on the bump 310 again;

when the bump 310 moves in the door opening direction, that is, when the bump 310 moves forward from the state of fig. 13 to the state of fig. 7, the bump 310 is located in the space between the blocking surface 61 and the toggle surface 51, the bump 310 presses the blocking surface 61 to drive the first rotating member 60 to move forward, so as to drive the second pin 02 and the first pin 01 to move forward, so as to drive the damping member 20 to move forward, referring to fig. 8, the bump 310 moves forward to press the blocking surface 61 to move the damping member 20 forward until the second pin 02 slides into the first chute 122 and stops at the position where the first rotating member 60 avoids the bump 310, and at this time, the blocking surface 61 enters the chute 12; referring to fig. 9, the protrusion 310 continues to move forward to press the pressing end 721, so that the third pin 03 moves in a direction away from the protrusion 310 and stops at a position where the second rotating member 70 is away from the protrusion 310, at this time, a gap is formed between the pressing end 721 and the protrusion 310, then, the protrusion 310 goes over the first rotating member 60 and the second rotating member 70 while continuing to move forward, and the second pin 02 moves to an end of the first inclined groove 122 away from the protrusion 310, the second pin 02 is limited in a front-back direction, and since the second inclined groove 212 is matched with the first inclined groove 122, the damping member 20 is also limited in the front-back direction, so that the damping member 20 can move along with the protrusion 310 and apply resistance when the protrusion 310 moves in the door-closing direction.

It can be known that, with the present technical solution, when the damper is in a failure state, the damper can still act on the protrusion 310 by pushing the door body 200 to move along the door closing direction, which is convenient for operation and maintenance, and the second rotating member 70, the first rotating member 60 and the toggle member 50 form a secondary rotating structure, which is convenient for avoiding the protrusion 310 and resetting the protrusion, and reduces the requirement for the structure of the first rotating member 60, wherein the structure of the second rotating member 70 is simple, practical and easy to implement, the first abutting surface 723, the second abutting surface 63 and the third abutting surface 62 are all configured such that the second pin 02 is located in the guide slot 121, and when the protrusion 310 moves backward to abut against the resetting portion 722, the protrusion 310 can act on the third abutting surface 62 during backward movement, thereby being more beneficial to driving the third pin 03 to move in a direction away from the protrusion 310, and the first abutting surface 723 further abuts against the second abutting surface 63, thereby being more beneficial to driving the third pin 03 to move in a direction away from the protrusion 310, therefore, the first rotating piece 60 and the second rotating piece 70 are more beneficial to avoiding the lug 310, and the structure is ingenious.
