1-5, according to an embodiment of the present invention, a suspension wheel buffer 100 includes a buffer body 102, the buffer body 102 has two side walls 101, a cavity 104 is defined between the two side walls 101 . A horizontal sliding slot 1022 is defined on each side wall 101 . The right end of the horizontal sliding slot 1022 forms an attitude adjustment slot 1024 extending downward. the

The suspension wheel buffer 100 further includes suspension wheel assemblies 20 arranged at the left and right ends of the buffer body 102 . When the suspension wheel buffer 100 is installed on the door body 200 (refer to Fig. 3-5), the suspension wheel assembly 20 is used to realize the movement of the door body 200 relative to the door frame (that is, the suspension rail 70 in Fig. 3-5). slide. The hanging wheel assembly 20 can be fixed on the door body 200 by means of, for example, screws 106 (refer to FIGS. 2-3 ). the

The hanger damper 100 further includes a slider 50 housed within said cavity 104 . The slider has two side walls 57 and a top wall 55 connecting them. The top wall 55 is provided with a card slot 52 facing downwards, and each side wall 57 is formed with a first protrusion 53 and a second protrusion 54 respectively extending into the horizontal slide groove 1022 of the corresponding side wall 101 . Since the protrusions 53 , 54 on each side wall 57 extend into the corresponding horizontal chute 1022 , the slider 50 can slide in the cavity 104 along the length direction of the horizontal chute 1022 . At the same time, it should be noted that when the slider 50 runs to the right end of the horizontal chute 1022, the second boss 54 will fall into the posture adjustment groove 1024, thereby impelling the posture of the entire slider 50 to change, that is, the sliding The block 50 slopes towards the right end of the horizontal chute 1022 . The effect of this stance tilt will be described later. the

The suspension wheel buffer 100 further includes a hydraulic oil cylinder 40 arranged in the cavity 104, which has a cylinder body 42 fixed in the cavity 104 and a pusher that can expand and contract in the length direction of the horizontal chute 1022 relative to the cylinder body 42. Rod 44. Meanwhile, the end of the push rod 44 is connected with the slider 50 . the

The suspension wheel buffer 100 further includes a tension spring 60 arranged in the cavity 104, one end of the spring 60 is fixed in the cavity 104, and the other end is fixed on the slide block 50, thereby realizing the sliding block 50 Elastic pull action. the

The suspension wheel buffer 100 further includes a suspension rail 70 for sliding the suspension wheel assembly 20 therein and a stop block 80 installed on the top inner wall of the suspension rail 70 . The stop block 80 has a base plate 82 for assembling the entire stop block 80 on the top inner wall of the suspension rail 70 and a locking block 84 extending downward from the base plate 82 . As the hanging wheel assembly 20 slides in the hanging rail 70 , the locking slot 52 of the sliding block 50 will be selectively locked into the locking block 84 or disengaged from the locking block 84 . the

The working process of the suspension wheel buffer 100 will be described in detail below. the

With reference to Figures 2-4, when the door needs to be closed (change from the state shown in Figure 5 to the state shown in Figure 4), the door body 200 slides toward the right side of the suspension rail 70 in Figure 5 relative to the suspension rail 70 (more precisely In other words, the two suspension wheel assemblies 20 of the suspension wheel buffer 100 slide in the suspension rail 70). During the sliding process of the door body 200, the buffer body 102 and all components mounted on it move to the right. The slider 50 gradually approaches the stopper 80 to the right, and then the locking groove 52 of the slider 50 and the catcher 84 of the stopper 80 engage with each other as it moves, thereby preventing the slider 50 from further sliding to the right. Since the slide block 50 is slidably arranged in the horizontal chute 1022, while the slide block 50 remains stationary, and the push rod 44 of the hydraulic cylinder 40 is fixed on the slide block 50, as the door body 200 continues to move forward, it is set in the buffer zone. The push rod 44 of the hydraulic oil cylinder 40 in the body 102 retracts in the cylinder body 42 gradually. Since the hydraulic cylinder 40 itself has resistance characteristics, that is, the extension or retraction of the push rod 44 relative to the cylinder body 42 occurs only when the hydraulic resistance in the cylinder body 42 needs to be overcome. Therefore, when the user When pushing the door body 200 hard to close the door, the user must overcome the hydraulic resistance of the oil cylinder 40 to achieve the purpose of closing the door. When the push rod 44 is fully retracted into the cylinder body 42, the door body 200 is completely closed. In other words, a complete fit between the door body 200 and the door frame (not shown) is realized. During this process, the tension of the tension spring 60 gradually decreases, so the spring 60 gradually returns to its original unstretched state. the

From another point of view, through the resistance characteristics of the hydraulic cylinder 40, the buffering effect on the door body when closing the door body is realized, thereby weakening or even avoiding the impact of the door body on the door frame, thereby protecting the door body or the door frame from damage; At the same time, the cushioning effect effectively reduces noise and increases the user-friendliness of the product. the

Referring to FIGS. 2-4 , when the door needs to be opened (from the state shown in FIG. 4 to the state shown in FIG. 5 ), the door body 200 slides toward the left side of the hanging rail 70 in FIG. 4 relative to the hanging rail 70 . During the sliding process of the door body 200, the buffer body 102 and all components installed thereon move to the left. Since the slider 50 is slidingly arranged in the horizontal chute 1022, while the slider 50 remains stationary, and the push rod 44 of the hydraulic cylinder 40 is fixed on the slider 50, as the door body 200 continues to move forward, the horizontal chute 1022 moves to the left relative to the slider 50, and the attitude adjustment groove 1024 gradually approaches the slider 50, eventually causing the second protrusion 54 of the slider 50 to fall into the attitude adjustment groove 1024, thereby causing the slider 50 to tilt to the right, Therefore, the locking groove 52 of the slider 50 is disengaged from the locking block 84 of the stop block 80 . After breaking away from the restriction of the locking block 84 , the sliding block 50 continues to slide to the left along with the operation of the door body 200 . During the sliding process, the push rod 44 protrudes relative to the cylinder body 42 , and the buffering effect of the door body 200 is realized due to the resistance characteristic of the hydraulic cylinder 40 . Simultaneously, during the above operation process, the tension spring 60 is stretched, thereby also increasing the resistance when opening the door body 200, the user needs to constantly overcome the resistance of the hydraulic cylinder 40 and the spring when opening the door body 200. 60 tension, thus achieving a cushioning effect. the

Referring to FIG. 4 , the present invention also provides a door device 300 installed with the above suspension wheel buffer 100 . The door device 300 includes a door body 200 and a suspension wheel buffer 100 installed on the door body 200 . the
