[0029] Example 1: As Figure 1-9 As shown, a novel door catcher includes a door catcher body and an abutment portion 1 mounted on a door. The door catcher body includes a door catcher mounting base 2 and a contact block 3. The contact block 3 slides back and forth between a closing / separating position 201 on the door catcher mounting base 2 and a terminal position 202 on the door catcher mounting base 2. A contact portion 301 is provided at a position corresponding to the abutment portion 1 on the contact block 3. The abutment portion 1 and the contact portion 301 contact or separate at the closing / separating position 201. When the door is opened, the abutment portion mounted on the door contacts the contact portion on the contact block at the closing / separating position. The door moves from the closing / separating position to the terminal position along with the contact block, improving the door catcher's guiding ability and smoothness during door movement, reducing noise generated when the abutment portion contacts the contact portion, thereby improving the quality of the door catcher.
[0030] The door catcher body includes a door catcher slide 4, which is slidably mounted on the door catcher fixing seat 2. One end of the contact block 3 is slidably mounted on the door catcher fixing seat 2, and the other end of the contact block 3 is mounted on the door catcher slide 4. The contact part 301 is exposed outside the door catcher slide 4 and the door catcher fixing seat 2. When the door is opened, the movement of the door causes the abutment part to carry kinetic energy and come into contact with the contact part of the door catcher. The force is transmitted to the contact block. Through the setting of the door catcher slide, the kinetic energy when the door is opened can be better distributed to the door catcher slide and the door catcher fixing seat, reducing the local stress on the door catcher and improving the durability and quality of the door catcher.
[0031] The door catch fixing base 2 is provided with a seat groove 203, and the door catch slide 4 is provided with a seat slider 401 at a position corresponding to the seat groove. The seat groove 203 is recessed from the outer surface of the door catch fixing base, and the seat slider 401 is protruding from the side of the seat slider 401 facing the door catch fixing base 2. The seat slider 401 slides in the seat groove 203. The arrangement of the seat slider and the seat groove makes the door catch slide move more smoothly on the door catch fixing base, and plays a guiding role in the sliding of the door catch slide on the door catch fixing base, thereby improving the stability of the sliding of the door catch slide.
[0032] The door catch fixing seat 2 protrudes laterally to form a side stop 204, and the side stop 204 and the door catch fixing seat 2 form a seat groove 203, which improves the stability of the door catch sliding seat sliding on the door catch fixing seat, thereby improving the stability of opening the door.
[0033] The door catcher body includes a buffer 5. The movable end of the buffer 5 is mounted on the door catcher slide 4, and the fixed end of the buffer 5 is mounted on the door catcher fixing seat 2. On the one hand, the door moves with the contact block, and under the retraction action of the buffer, the door is slowly moved, realizing the function of pulling the door open. On the other hand, when the abutment part contacts the contact part, the buffer can further offset the force at the time of contact and reduce the generation of noise.
[0034] The door catcher body includes a spring 6. One end of the spring 6 is mounted on the door catcher fixing seat 2, and the other end of the spring 6 is mounted on the door catcher slide 4. When the door is closed, the spring is in a stretched state, the contact block is located at the opening / closing position, and the buffer is in an open state. The spring is configured to provide power for the sliding between the door catcher slide and the door catcher fixing seat, so that the door catcher slide can slide better on the door catcher fixing seat.
[0035] The door catch fixing base 2 is provided with an inwardly recessed block groove 205, and the contact block 3 is provided with a block sliding part 302 adapted to the block groove 205. The block sliding part 302 is provided to protrude outward from the surface of the contact block 3 and slides within the block groove 205. The block groove and the block sliding part guide the movement of the contact block, improving the stability and smoothness of opening the door. Optionally, the sliding method between the contact block and the door catch fixing base can also be magnetic attraction. The path between the opening / closing station and the end station is magnetic, and the contact block is made of a magnetic material. Through magnetic attraction, the contact block can move back and forth between the opening / closing station and the end station.
[0036] The contact block 3 has a rotating post 303 protruding from the door suction slide 4 on the side facing the door suction slide 3. The door suction slide 3 has a rotating hole 402 at the position corresponding to the rotating post 303. The rotating post 303 is rotatably disposed in the rotating hole 402. The contact block and the door suction slide are rotatably assembled, which can be adapted to different door opening methods and provides the door suction's adaptability range.
[0037] Wherein, the block slide 205 extends outward from one end near the engagement / disengagement station 201 to form a left extension 2051 and a right extension 2052. The left extension 2051 and the right extension form an engagement / disengagement space 2052. The shape of the engagement / disengagement space is adapted to the shape of the block slide. When the block slide moves to the side of the block slide near the left extension, it will deflect along the shape of the left and right extensions, so that the contact part faces the abutment part, which facilitates the contact between the abutment part and the contact part. When the door is closed, the two ends of the block slide are located at the left extension and the right extension respectively. At this time, the contact block is in a stopped state. When the door is opened, the abutment part contacts the contact part, causing the block slide to rotate and move along the direction of the seat slide.
[0038] The contact block 3 has an inwardly recessed opening 304 at a position corresponding to the opening and closing space. The contact part is located on the side of the opening facing the abutment part. By setting the opening, the abutment part can make better contact with the contact part, and at the same time, the possibility of the abutment part and the contact part separating is reduced, and the smoothness of opening the door is improved.
[0039] Specifically, an inwardly recessed portion is provided at the contact point between the outer surface of the rotating block and the contact block, and a raised portion adapted to the recess is provided at the corresponding position of the door suction slide, thereby improving the stability of the contact block rotation.
[0040] The contact block 3 has a forward protrusion 305 that rises from bottom to top near the contact portion, and the side of the forward protrusion 305 near the contact portion is on the same plane as the outer surface of the contact portion.
[0041] The contact block 3 has a rear protrusion 306 that rises from bottom to top near the contact portion, and the side of the rear protrusion 306 near the contact portion is on the same plane as the outer surface of the contact portion.
[0042] The front protrusion 305 is inclined between the side of the block rotating post 303 and the side of the rear protrusion near the block rotating post.
[0043] The bottom of the door catch fixing seat 2 is recessed inward to form an inner cavity, and the buffer is disposed in the inner cavity.
[0044] The inner cavity is provided with a through-hole at one end near the movable end of the buffer, and the door suction slide is provided with an embedding groove 403 at one end near the buffer. The embedding groove 403 is recessed inward from the end of the door suction slide toward the buffer, and the movable end of the buffer is assembled in the embedding groove.
[0045] The distance between the outermost end of the left extension 2051 and the outermost end of the right extension 2052 is equal to or greater than the distance between the two ends of the block sliding part 302.
[0046] The block slide 302 is provided with a guide portion 3021 on the side near the left extension portion, and the guide portion is arranged to converge from the outside to the inside.
[0047] The right extension 2052 is provided with an arc-shaped part at the junction with the block groove 205. The arc-shaped part improves the smoothness of the contact block entering the opening and closing space, thereby improving the quality of the door closer, reducing the wear of the contact block due to hard jamming, and improving the smoothness of opening the door.
[0048] Specifically, a clearance cutout is provided at the position corresponding to the contact block 3 on the door suction slide 4. The clearance cutout is recessed from the outside to the inside to form a clearance cavity 404. The clearance cavity is inclined near the inner wall of the block rotating column.
