Description

Technical Field

[0001] The utility model relates to a door stopper, in particular to a buffer and silent door stopper. Background Art

[0002] Door stops are commonly used accessories in doors, mainly used to fix the door to prevent it from closing due to wind or accidental collision, and violently hitting the door frame, causing damage to the door frame and door leaf. The usual practice is to install door stops on the door leaf and its corresponding wall or ground respectively.

[0003] Currently, most door catches on the market are divided into magnetic and non-magnetic types. Magnetic door catches can cause a hard collision between the door catch rod and the door catch base, making a noise. Furthermore, magnetic door catches require magnetic materials, which can rust over time, affecting their aesthetics. Non-magnetic door catches generally have poor cushioning properties and are easily damaged by collisions. Therefore, there is a need for a new door catch that is quieter and has a simpler structure. Utility Model Content

The locking mechanism is pressurized by the door suction rod, and the locking mechanism cooperates with the buffer mechanism to move, thereby realizing locking and unlocking of the door suction rod.

[0006] The locking mechanism includes a swing arm hingedly mounted on the base, a guide member slidably mounted in the base, and a spring. The guide member is pushed by the spring to always elastically press on the swing arm, pushing the swing arm to generate deflection power.

[0023] The present invention is further described below in conjunction with the accompanying drawings. A buffered silent door stopper comprises a door stopper rod and a door stopper seat, the door stopper seat comprising a top cover 2, a bottom cover 3, and a seat 4. The door stopper seat is provided with a locking mechanism 7, and the seat 4 is provided with a buffer mechanism and a locking mechanism 7. The locking mechanism is pressed by the door stopper rod, and the locking mechanism and the buffer mechanism cooperate to move, thereby locking and unlocking the door stopper rod.

[0024] The locking mechanism 7 includes a swing arm 70 hingedly mounted in the base, a guide member 72 slidably mounted in the base, and a spring 73. The guide member is pushed by the spring to always elastically apply pressure on the swing arm, pushing the swing arm to generate deflection power.

[0025] The swing arm 70 is provided with a U-shaped opening 701 and an arc-shaped portion 702 at the bottom. The interior of the guide member 72 is a cavity structure. One end of the spring rests on the seat body and the other end rests in the cavity structure.

[0026] A guide wheel 71 is installed on the guide member 72 through a pin shaft. When the locking mechanism is working, the guide wheel always slides against the arc portion 702 of the swing arm under the pressure of the spring. After the swing arm is subjected to force, it rotates counterclockwise, and the U-shaped opening clamps the door suction rod to lock the door leaf.

[0027] The buffer mechanism 5 includes a damper 51 and a block 52, which are respectively installed in the guide groove of the base body (not marked in the figure). The damper is connected to the block. When the swing arm is closed, it extends into the active trajectory of the block and pushes the block to retract and reset to generate motion damping.

[0028] A convex portion 521 is provided on the stopper, and a limiting groove 32 is provided on the bottom cover 3. Correspondingly, a limiting groove (not marked in the figure) is also provided on the base body. The convex portion extends into the limiting groove and slides. When the door suction rod hits the swing arm, the swing arm pushes the stopper to slide in the limiting groove, and transmits the impact force to the damper, which plays a role of absorption and buffering.

[0029] The swing arm 70 is mounted on the pin 43 of the seat body 4 and can rotate around the pin 43. A damping arm is extended on the side of the swing arm toward the stopper. Correspondingly, an extrusion slope is provided on the side of the stopper toward the damping arm. The contact between the damping arm and the extrusion slope generates power to push the stopper to move.

[0030] The bottom cover 3 is installed between the base and the surface cover. A U-shaped opening 33 is provided on the bottom cover 3. The surface cover 2 is also provided with a clearance groove corresponding to the U-shaped opening 33 for the door suction rod to pass through.

[0031] The second embodiment of the present invention: the locking mechanism includes a second swing arm 80 hingedly mounted on the base body, and a locking arm 801 is provided on the second swing arm, and its length extends to the edge of the base body. The swing arm is in an arc shape 802 on the side facing the buffer component and rests on the buffer component, and the swing arm is in an elliptical shape 803 on the side facing the locking mechanism. The interior of the guide member 72 is a cavity structure, and the spring is installed in the cavity structure. A guide wheel 71 is installed on the top of the guide member, and the guide wheel is supported and arranged to slide at the ellipse at the right end of the swing arm.

[0032] Working principle: When the door suction rod collides with the swing arm, the swing arm is subjected to force and transmits the force to the damper through the block. At this time, the damper is in a compressed state. When the arm swings, under the elastic force of the spring (the spring is in an extended state at this time), the right side of the swing arm is pushed upward through the guide and guide wheel, causing the swing arm to rotate counterclockwise around the pin. At this time, the U-shaped opening of the swing arm is buckled on the door rod, thereby locking the door, and it is now in a locked state. When the swing arm is hit again, the cylinder damper resets and pushes the block upward. At this time, the swing arm rotates clockwise, and the U-shaped opening of the swing arm is disengaged from the door rod, thereby releasing the lock. This is repeated to lock and release the door leaf. Under the action of the cylinder damper, the door suction absorbs part of the kinetic energy when it is subjected to external force, thereby reducing the noise generated during the collision.

[0033] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
