Abstract
Description
Technical Field
[0001] The utility model relates to a door stopper, in particular to a windproof and damping 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 catchers on the market are hard-collision door catchers. When in use or when the door is blown by wind, the door catch rod and door catch seat will collide hard, making a noise. Most door catchers do not have internal buffers, resulting in poor performance. Hard collisions can easily cause damage to the door catcher and also produce noise. Therefore, there is a need for a new door catcher that is less noisy and has a buffering damping function. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a buffering and windproof damping door stopper.
[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: the suction seat includes a surface cover, a bottom cover and a seat body, a swing arm is provided in the seat body, the swing arm rests on the buffer mechanism, a pulley is provided on the swing arm, the pulley rests on the pushing device, and the pushing device pushes the pulley to drive the swing arm to rotate, thereby locking the suction rod.
[0006] The swing arm is connected through a pin on the base body and can rotate around the pin. A U-shaped opening is provided on the swing arm, and a slot is provided at one end of the swing arm facing the pushing device. The pulley is installed in the slot through a pin and can rotate.
[0007] The pushing device includes a guide block and a spring. The interior of the guide block is a cavity structure, and the spring is installed in the cavity. The spring is always elastically squeezed on the guide block to push the swing arm to generate deflection power.
[0008] The buffer mechanism includes a damper and a block. The base body is provided with grooves for installing the damper and the block. The damper fits with the block to provide damping when the block slides in the groove. When the swing arm is closed, it extends into the active track of the block and pushes the block to retract and reset to generate motion damping.
[0009] The surface of the stopper is provided with a convex portion, the bottom cover is provided with a limiting groove corresponding to the convex portion, the convex portion extends into the limiting groove and slides, the bottom cover is provided with a guide groove, and the guide block extends into the guide groove and slides.
[0010] The swing arm is connected through a pin on the seat body and can rotate around the pin. 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 damping arm contacts the extrusion slope to generate power to push the stopper to move.
[0011] The bottom cover is installed between the base and the surface cover. The bottom cover is provided with a U-shaped opening. The surface cover is also provided with a space-avoiding groove corresponding to the U-shaped opening for the door suction rod to pass through.
[0012] The utility model has the following beneficial effects: when the door suction collides, the impact force of the door rod on the suction seat can be effectively absorbed by the oil cylinder damper and the interaction force of the spring, which has a better buffering effect, so that the door leaf makes less noise when in use. At the same time, due to the provision of a guide part and a convex portion on the surface of the block, and the corresponding limit groove and guide groove are provided on the bottom cover, it is more secure when in use.

[0020] The present invention is further described below in conjunction with the accompanying drawings. A windproof damping door stopper comprises a suction rod and a suction base. The suction base comprises a top cover 2, a bottom cover 3, and a base 4. A swing arm 7 is disposed within the base 4 and rests against a buffer mechanism 5. A pulley 72 is disposed on the swing arm and rests against a pusher 6. The pusher pushes the pulley to rotate the swing arm, thereby locking the suction rod.
[0021] The swing arm 7 is connected through the pin 43 on the base body 4 and can rotate around the pin 43. A U-shaped opening 71 is provided on the swing arm, and a slot 73 is provided on one end of the swing arm facing the pushing device. The pulley 72 is installed in the slot through a pin and can rotate. The function of the pulley is to make the contact surface smoother when the pushing device pushes the swing arm to move.
[0022] The pushing device 6 includes a guide block 61 and a spring 62. The interior of the guide block is a cavity structure. One end of the spring rests on the seat body, and the other end rests on the cavity of the guide block. The spring is always elastically squeezed on the guide block. The guide block abuts against the pulley, pushing the swing arm 7 to rotate counterclockwise. When the swing arm rotates to the suction rod position, it can be locked.
[0023] The buffer mechanism 5 includes a damper 51 and a block 52. The base body 4 is provided with grooves for installing the damper and the block. The block damper fits with the block to provide damping when the block slides in the groove. 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.
[0024] The surface of the stopper is provided with a protrusion 52a, and the bottom cover 3 is provided with a limiting groove 32 corresponding to the protrusion. The protrusion extends into the limiting groove and slides. The bottom cover 3 is provided with a guide groove 31, and the guide block extends into the guide groove and slides. The setting of the limiting groove and the guide groove makes the suction seat more stable during operation.
[0025] A damping arm extends from one side of the swing arm toward the stopper, and correspondingly, an extrusion slope is provided on the side of the stopper toward the damping arm. The damping arm contacts the extrusion slope to generate power to push the stopper to move. When the swing arm is subjected to an impact force, the damping arm transmits the force to the damper to cushion the impact of the external force.
[0026] 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.
[0027] 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 retracted state. When the arm is swung under the elastic force of the spring (the spring is in an extended state at this time), the guide block is against the pulley, causing the lower right end of the swing arm to push upward, and the swing arm rotates counterclockwise around the pin. At this time, the U-shaped opening of the swing arm is stuck on the door rod, thereby locking the door. When force is applied to the swing arm again, the lower right end of the swing arm presses the guide block (the spring is in a compressed state), and the damper is free from the pressure of the spring. At this time, the reset pushes the block upward, thereby pushing the swing arm to rotate clockwise, and the U-shaped opening of the swing arm is separated from the door rod, thereby releasing the lock. This is repeated to lock and unlock the door leaf. When the door suction is subjected to external force, the external force is absorbed by the damper, thereby reducing the noise generated during the collision.
[0028] 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.
