[0023] like Figures 1-8 As shown, a silent door catcher includes a door connector 100 mounted on a door panel and a floor catch 200 mounted on the ground. The door connector 100 contains a sliding rod 110 and an elastic element 120 for controlling the return of the sliding rod 110. The floor catch 200 includes a fixed base 210 and an adsorption element 220. The adsorption element 220 magnetically attracts the sliding rod 110, thus limiting the door panel's position. Specifically, a magnet can be placed at the bottom of the sliding rod 110, and the adsorption element 220 can be a magnetically attracted metal sheet; alternatively, a metal sheet can be placed at the bottom of the sliding rod 110, and the adsorption element 220 can be a magnet; or a magnet can be placed at the bottom of the sliding rod 110, and the adsorption element 220 can be a magnet. The floor catch 200 has an elastic stop 230 near the door connector 100. The elastic stop 230 is higher than the adsorption element 220, and the elastic stop 230 has a notch 231 in the middle. The minimum width of the notch 231 is smaller than the width of the bottom surface of the sliding rod 110.
[0024] The notch 231 is narrowest on the side closest to the door connector 100, and the width of the notch 231 gradually increases from the outside to the inside.
[0025] The elastic stop portion 230 includes a left stop block 232 and a right stop block 233 symmetrically arranged. The left stop block 232 and the right stop block 233 include a trapezoidal portion 234 integrally formed from top to bottom, a first connecting portion 235, and a first boss 236. The fixing base 210 is provided with a trapezoidal through hole 211 corresponding to the trapezoidal portion 234 and a first groove 212 corresponding to the first boss 236.
[0026] like Figures 2-4 As shown, the door catch 200 has an elastic stop 230 near the door connector 100. When the movable rod 110 moves toward the door catch 200, it first strikes the elastic stop 230. After the speed of the movable rod 110 decreases, it then comes into contact with the suction element 220, greatly reducing the collision noise. The elastic stop 230 also prevents the door from closing due to wind or other external forces. When the door catch is to be opened, simply pull the door outward by hand. When the force exceeds the two stops on the left and right, the movable rod 110 and the door disengage from the door catch 200, and the movable rod 110 retracts upward into the door connector 100.
[0027] The elastic anti-collision member 240 is provided on the floor-suction member 200 away from the door connecting base 100. The elastic anti-collision member 240 comprises an anti-collision part 241, a second connecting part 242 and a second boss 243 which are integrally formed from top to bottom. The fixed seat 210 is provided with a second through hole 213 corresponding to the anti-collision part 241 and a second recess 214 corresponding to the second boss 243. The trapezoidal part 234 and the first connecting part 235 form a first clamping groove 237, and the anti-collision part 241 and the second connecting part 242 form a second clamping groove 244. The suction member 220 is clamped into the first clamping groove 237 at one end and the second clamping groove 244 at the other end. When the door is pushed to the head, the elastic anti-collision member 240 bears the impact of the movable rod 110, preventing the movable rod 110 and the fixed seat 210 from being damaged by impact.
[0028] The door connecting base 100 comprises a shell 130 and a base 140. The base 140 comprises a bottom plate 141 connected to the door, a side plate 142 provided on the side of the bottom plate 141, an upper plate 143 provided on the upper end of the bottom plate 141, and a lower plate 144 provided on the lower end of the bottom plate 141. The movable rod 110 is arranged in the shell 130. The upper plate 143 and / or the lower plate 144 of the base 140 is provided with a guide block 145, and the shell 130 is provided with a sliding groove 131 matched with the guide block 145. The bottom plate 141 is provided with an elastic clamping block 150, and the shell 130 is provided with a limiting recess 132 corresponding to the elastic clamping block 150. The base 140 is provided with a cavity 146 for mounting the elastic clamping block 150. The elastic clamping block 150 comprises an end cover 151 covering the cavity 146, a clamping member 152, and a spring 153 arranged between the end cover 151 and the clamping member 152. With the above structure, the shell 130 and the base 140 can be clamped or separated by sliding the shell 130, which is simple and fast.
[0029] The bottom of the movable rod 110 is provided with a buffer pad 111, which can further reduce the noise generated when the movable rod 110 and the suction member 220 collide.
[0030] During installation, first, the fixed seat 210 is fixed at the position where it needs to be installed by screws. Then, the suction member 220 is aligned with the second clamping groove 244 on the elastic anti-collision member 240 and pushed in. Then, the other end of the suction member 220 is pressed down into the first clamping groove 237 provided on the left and right stop blocks, and the suction member 220 is fixed in the fixed seat 210. Thus, the floor-suction member 200 is installed. Then, the base 140 is installed on the door by screws, and the shell 130 is aligned with the upper and lower guide blocks 145 on the base 140. After being pushed to the bottom, the clamping member 152 in the base 140 is clamped into the limiting recess 132 of the shell 130, and the door connecting base 100 is installed.
