The side of the mounting frame 7 is provided with an outwardly bent fixing part 71, a fixing hole is arranged in the middle of the fixing part 71, and the fixing frame 1 can be fixedly connected to the door leaf 6 through a screw arranged in the fixing hole. The door stopper seat 2 is arranged on the ground or the wall surface, and the middle part is provided with a limit groove 21 which is used for locking the door leaf 6 by being matched with the first spring 41, the damping mechanism 5, the connecting bracket 3 and the roller 31 in the fixing frame 1.
The connecting bracket 3 is composed of two bent plate bodies which are connected together to form a space for installing a component. Wherein the upper end of the connecting bracket 3 is hinged in the mounting groove 11, the lower end extends outwards and is provided with a roller 31 at the end. As shown, the roller 31 is clamped between the two plates. A flexible material, such as rubber, silica gel, etc., is provided on the surface of the roller 31 for noise reduction.
The lower end of the first spring 41 is connected to the middle of the connection bracket 3, and the upper end is fixed in the installation groove 11 and applies a pulling force toward the inside of the limit groove 21 to the connection bracket 3. As shown in fig. 3, in the initial state, the tensile force direction of the first spring 41 passes through the rotation shaft of the connection bracket 3, and thus the connection bracket 3 is not rotated; as shown in fig. 4, when the roller end of the connection bracket 3 moves to the left in the drawing, the pulling force direction of the first spring 41 is located at the left side of the rotation axis of the connection bracket 3, and drives the connection bracket 3 to rotate clockwise. In addition, in the initial state, the direction of the tension of the first spring 41 may be set to be located on the right side of the rotation axis of the connection bracket 3, and at this time, the first spring 41 may drive the connection bracket 3 to rotate counterclockwise, but the lower end of the connection bracket 3 may abut against the fixing frame 1, and the connection bracket 3 may be in a fixed state in the initial state.

In this embodiment, the groove wall of the limit groove 21 near the side of the fixing frame 1 is lower than the groove wall of the opposite side, when the fixing frame 1 moves towards the door stopper 2 along with the door leaf 6, the roller 31 passes over the groove wall of the lower side of the limit groove 21 first, then abuts against the groove wall of the higher side of the limit groove 21, and the roller end of the connecting bracket 3 moves leftwards relative to the fixing frame 1 along with the continuous movement of the door leaf 6, after a preset distance of movement, the pulling force direction of the first spring 41 can be located at the left side of the rotating shaft of the connecting bracket 3, and then the connecting bracket 3 is driven to rotate clockwise, and then the roller 31 is clamped in the limit groove 21, so as to complete the locking action of door stopper, as shown in fig. 5 in detail. The door stopper in this embodiment can make the door stopper smoothly complete the locking action due to the presence of the damping mechanism 5 without generating a large noise.
Wherein the preset distance is selected in the range of 0-10mm, which is related to the relative position of the first spring 41 and the connection bracket 3, and which is zero when the direction of the tension of the first spring 41 passes through the rotation axis of the connection bracket 3; when the pulling force direction of the first spring 41 is located on the right side of the rotation axis of the connection bracket 3 and is farther from the rotation axis, the preset distance is also larger.
In this embodiment, the slider 32 is provided on the side surface of the connection bracket 3, and the circular arc chute 12 for accommodating the slider 32 is provided on the wall of the installation groove 11, and the center of the chute 12 is concentric with the rotation axis of the connection bracket 3. Thus, when the connecting bracket 3 rotates in the mounting groove 11, the sliding block 32 also slides in the sliding groove 12, so that on one hand, the stability of the connecting bracket 3 in the mounting groove 11 can be improved, and on the other hand, the rotation amplitude of the connecting bracket 3 can be controlled by changing the length of the sliding groove 12.
In addition, in this embodiment, a positioning clamping seat 33 is arranged in the middle of the two plate bodies of the connecting bracket 3, the positioning clamping seat 33 is in a cylindrical shape as a whole, and an arc-shaped clamping groove 34 is arranged in a side surface partial area of the positioning clamping seat; a positioning buckle 13 is rotationally arranged in the mounting groove 11, and one end of the positioning buckle is provided with an arc-shaped clamping part 14 which is clamped in the clamping groove 34; meanwhile, a second spring 42 is arranged in the mounting groove 11, and the second spring 42 applies an acting force to the positioning buckle 13 to enable the clamping part 14 to be tightly abutted against the clamping groove 34, so that the connecting bracket 3 is fixed to a certain extent through the cooperation of the positioning buckle 13 and the positioning clamping seat 33. As shown in fig. 3 to 6, the second spring 42 is a torsion spring, one end of which abuts against the side wall on the installation side, and the other end abuts against the positioning buckle 13 (the other end is not shown in the drawings because the figures are cross-sectional views), so that the positioning buckle 13 has a tendency to rotate clockwise, therefore, before the connecting bracket 3 is interlocked with the door holder 2, the positioning buckle 13 can make the roller end of the connecting bracket 3 be stably located outside the installation groove 11, after the door leaf 6 is opened to a certain extent, the roller 31 is blocked by the limiting groove 21 after contacting the door holder 2, so that the clamping force of the positioning buckle 13 can be overcome, the positioning buckle 33 is separated from the positioning buckle 13, and the connecting bracket 3 can rotate clockwise, and can be interlocked with the door holder 2, thereby realizing locking door suction.
In the daily use process, if the roller 31 is touched by mistake, the connecting bracket 3 rotates clockwise, and then the first spring 41 can drive the connecting bracket 3 to rotate continuously, so that the roller end is changed from the right side to the lower side in the figure, namely, the situation shown in fig. 6. In this case, if the door leaf 6 gradually approaches the door stopper 2, the roller end of the connecting bracket 3 will abut against the side surface of the door stopper 2, and cannot enter the limiting groove 21, and the locking operation cannot be completed. Therefore, in this embodiment, a roller seat 35 is further disposed at the lower end of the connection bracket 3, and the roller seat 35 is a U-shaped seat body slidably disposed between the two plate bodies of the connection bracket 3, and can slide up and down along the lower half portion of the connection bracket 3, and meanwhile, the roller 31 is hinged between the roller seats 35 and can slide along with the roller seat 35; the third spring 43 is further arranged on the connecting bracket 3 and is used for pushing the roller seat 35 to reset, specifically, the third spring 43 applies an outward acting force to the roller seat 35, so that the roller seat 35 can be positioned at the end part of the connecting bracket 3 when no external force is applied; in addition, a guide portion 22 is further disposed on a side of the door stopper 2 near the fixing frame 1, and the width of the guide portion is not greater than the width of the roller 31, and the side surface is an inclined guide surface, so that the guide portion can enter the middle of the two plates of the connecting bracket 3.
Under this structure, if the lower end of the connecting bracket 3 faces downward before being clamped into the limiting groove 21, when the connecting bracket gradually approaches the door stopper seat 2, the roller 31 will firstly abut against the guide portion 22 and slide upward along with the roller seat 35 under the action of the guide surface until the connecting bracket passes over the guide portion 22 and is pushed into the limiting groove 21 by the third spring 43, so that the locking action can be completed, the problem of the erroneous touching of the roller 31 is solved, and the buffering noise reduction door energy absorption can stably run for a long time.
