Description

A kind of shock absorbing and damping pulley mechanism

Technical field

The invention relates to the field of damping equipment, and in particular to a shock absorbing and damping pulley mechanism.

Background technique

Due to the deceleration and vibration reduction effect of the damper itself, the damper is often used as a functional component for vibration reduction and energy dissipation. The damper is usually installed on a device where a collision occurs to slow down the impact between collision components, such as, In the application of sliding doors, the sides of the moving door leaf will collide with the inside of the door outer frame during the opening and closing process. Therefore, a damper is usually set on the top of the moving door leaf. During the opening and closing process of the moving door leaf, the damper Provide damping and deceleration to the moving door leaf to reduce the impact force when the moving door leaf fits the outer frame of the door.

The existing damper is fixedly connected to the door leaf. When the door leaf jumps upward, the door leaf will drive the damper to jump upward and cause the damper pulley to come off the track, thus causing a jump gap between the damper pulley and the track. When the damper falls back, the pulley will collide with the track. If the damper lacks a shock-absorbing structure, the impact will cause vibration damage to the damper;

In addition, the damper includes a damping body and a pulley. In the existing damper, the pulley is first rotated and set on the pulley seat, and then one end of the pulley seat is connected to the splint of the damping body. The pulley seat is located outside the splint, so the splint cannot The pulley seat is clamped and fixed, so the connection between the pulley seat and the splint is not firm, and the damper has the defect of poor impact resistance.

Contents of the invention

In order to overcome at least one drawback of the above-mentioned prior art, the present invention provides a shock absorbing and damping pulley mechanism.

The technical solution adopted by the present invention to solve the problem is:

A shock-absorbing and damping pulley mechanism includes:

Pulley assembly, the pulley assembly includes a pulley seat;

A jump shock absorbing device, which is provided on the pulley seat to eliminate the jump gap and/or vibration impact of the pulley assembly;

Damping assembly, the damping assembly includes two parallel clamping plates, and the pulley is seated between the two clamping plates.

In the present invention, the jump shock absorbing device is installed on the pulley assembly. The jump shock absorbing device is a moving body. For example, it plays a role in eliminating the jump gap of the door leaf. Furthermore, the jump shock absorbing device has an elastic shock absorbing function and can eliminate the damping pulley. The impact and vibration of the mechanism prevents damage to the damping pulley mechanism; in addition, the pulley seat is located between the two splints, that is, the pulley seat and the splint are integrally connected, which enhances the stability of the overall connection of the damping pulley mechanism and at the same time enhances the Impact strength.

Further, the bounce damping device includes a mounting base, a rotating body and an elastic body;

The rotating body is arranged in the mounting base and rotates in the mounting base. The elastic body is arranged in the mounting base and is located at the bottom of the mounting base.

Therefore, the runout damping device uses the elastomer to eliminate the runout gap. At the same time, the elastomer plays a shock-absorbing role, which better avoids impact damage to the damping pulley mechanism.

Further, the elastic body is a spring, a spring piece, or an elastic clip.

Therefore, the elastomer can be a spring, a spring piece, or an elastic clip. First of all, the spring is more universal in application and more standardized in use; the spring piece and the elastic clip have the advantages of simple structure and convenient manufacturing.

Further, the beating shock absorbing device further includes a connecting body, one end of which is connected to the rotating body, and the other end is used to connect to the moving body.

Therefore, the connecting body is used to connect the rotating body and the moving body. The connecting body, the rotating body and the moving body can be connected in a detachable manner such as threaded connection, thereby improving the efficiency of installation and connection between components.

Further, the pulley assembly further includes a pulley that is rotatably mounted on the splint and the pulley seat.

As a result, the pulley is rotated between the splint and the pulley seat, and the pulley seat, splint and pulley are integrally connected, which better ensures the stability of the overall connection of the damping pulley mechanism and further enhances the impact resistance of the damping pulley mechanism.

Further, there are at least two pulley seats, and the distance between the centers of the two outermost pulleys of the two pulley seats is less than or equal to the length of the splint extending along the running direction of the pulley assembly.

As a result, the pulley seat is completely clamped by the splint, making the installation of the pulley seat more stable and avoiding the problem of loosening of the pulley seat.

Further, the damping assembly further includes a movable block and a damping tube. The damping tube is arranged between the two clamping plates. The two movable blocks are respectively rotatably connected to both ends of the damping tube. The movable The block is slidingly connected to the clamping plate, the top surface of the movable block is higher than the top surface of the clamping plate, and the two movable blocks are located between the two pulley seats.

Therefore, the damping pulley mechanism is provided with two movable blocks. The two movable blocks can realize bidirectional damping of the damping pulley mechanism, increasing the multi-directionality of the damping function of the damping pulley mechanism.

Further, the damping assembly further includes a tension spring, and both ends of the tension spring are respectively connected to the two movable blocks.

Therefore, the contraction of the damping tube is assisted by the tension of the tension spring, ensuring the smooth progress of the shrinking process of the damping tube.

Furthermore, it also includes a splint connection part, which is provided between two of the splints and connected to the two splints respectively.

Therefore, the splint connection part is used for connection between two splints, and the splint connection part plays a supporting and fixing role for the two splints, effectively preventing deformation of the splints during use.

Further, the clamping plate connection part includes an upper clamping block, a lower clamping block and a connecting block. The upper clamping block and the lower clamping block are arranged up and down and form a hollow through cavity. The lower clamping block is connected with the two said clamping blocks respectively. For splint connection, both sides of the upper clamping block and the lower clamping block are connected by connecting blocks respectively, and the two connecting blocks are respectively connected to the two splinting plates. The damping tube is inserted into the hollow cavity.

As a result, the hollow cavity wraps and limits the damping tube, effectively ensuring the stability of the damping tube during expansion and contraction.

Further, the pulley assembly further includes a rotating shaft and a sleeve. The sleeve is provided in the splint and the pulley seat. Each of the pulley seats is rotatably connected to at least one of the rotating shafts. The rotating shaft rotates. It is rotatably connected in the sleeve, and the pulleys are provided at both ends of the rotating shaft.

Therefore, the shaft sleeve isolates the rotating shaft from the damping component and the pulley seat. When the rotating shaft rotates, it will not cause wear to the damping component and the pulley seat device, thereby extending the service life of important components.

To sum up, the shock absorbing and damping pulley mechanism provided by the present invention has the following technical effects:

1. A beating shock absorbing device is installed in the pulley seat. The moving body is connected to the beating shock absorbing device through a connecting body. When the moving body beats, the connecting body only drives the mounting base and the rotating body to beat upward. The pulley assembly and damping assembly will not move upward. jump up, so the pulley will not break away from the track, thereby eliminating the gap between the pulley and the track, ensuring continuous contact between the pulley and the track; when the moving body falls, the mounting base and the elastomer are in elastic contact, and the mounting base will not directly pull the pulley The seat undergoes a rigid collision;

In addition, the rotating body provided in the mounting base is connected to the moving body through the connecting body. Since the mounting base is in elastic contact with the elastomer, the elastic body plays a buffering role on the mounting base. The rotating body in the mounting base will drive the moving body to decelerate, reducing the speed of the moving body. The collision impact at the bottom of the moving body is reduced, which avoids impact damage to the damping pulley mechanism and the moving body and also reduces the noise during use.

2. In the present invention, two pulley seats are arranged between two splints, and the outermost surfaces of the two pulley seats are located between the two ends of the splints, so that the pulley seats can be moved along the length direction of the damping tube through the two splints. The side of the pulley is completely enclosed, that is, the pulley part, the pulley seat and the splint of the damping component are connected in an integrated manner, which better ensures the connection strength of the pulley seat and the splint, strengthens the stability of the overall connection of the damping pulley mechanism, and further enhances the Impact strength of damped pulley mechanism.

In this embodiment, the rotating body 22 is a sphere with a threaded hole in the middle, so the connecting body 3 is a screw that matches the threaded hole;

In the initial state, the damping tubes 53 of the first damping pulley mechanism 15 and the second damping pulley mechanism 16 are in an extended state, and the slide blocks of the two movable blocks 52 are respectively locked in the slots 8 corresponding to the sliding slot 7. Since the door leaf Due to the gravity, the mounting base 21 presses on the wave multi-layer spring, so the wave multi-layer spring is in a compressed state. At this time, the top surface of the upper clamp body of the mounting base 21 does not contact the upper top surface of the accommodation hole;

Since the catch groove 8 is bent downward, the opening of the hook pull groove 9 is in an outward and obliquely upward state. At this time, the highest point of the outer wall of the hook pull groove 9 is lower than the bottom surface of the boss of the stopper 17, and the hook pull groove 9 is in an outward and oblique upward state. The highest point of the inner wall surface of groove 9 is higher than the bottom surface of the boss of stopper 17;

The movement process of the door leaf is:

(1) Push the door leaf to the right to close, and the two damping pulley mechanisms follow the door leaf to move to the right. The inner wall surface of the hook groove 9 of the movable block 52 at the right end of the first damping pulley mechanism 15 and the side surface of the boss of the right stopper 17 After contact, the movable block 52 at the right end of the first damping pulley mechanism 15 is detached from the slot 8, and the opening of the hook groove 9 of the movable block 52 at the right end of the first damping pulley mechanism 15 rotates upward and is in an upward opening state. The boss of the side block 17 is completely engaged in the hook groove 9 of the movable block 52 at the right end of the first damping pulley mechanism 15. The door leaf continues to move to the right, and the movable block 52 at the right end of the first damping pulley mechanism 15 moves along the sliding groove. 7 slides to the left, the damping tube 53 of the first damping pulley mechanism 15 shrinks and damps and decelerates the door leaf. At this time, the tension spring 54 of the first damping pulley mechanism 15 will also shrink. When the damping tube of the first damping pulley mechanism 15 53 is completely retracted. At this time, the right side wall of the door leaf just fits the inner wall of the right frame strip, and the door leaf is completely closed;

Due to the collision between the right side wall of the door leaf and the inner wall of the right frame, the right end of the door leaf jumps upward. At this time, the auxiliary roller on the right side of the bottom surface of the door leaf follows the door leaf and jumps upward. The auxiliary roller on the right side of the bottom surface of the door leaf is in contact with the lower track. There is a slight detachment, and the door leaf drives the mounting base 21 and the rotating body 22 to jump to the top surface of the accommodation hole through the connector 3 connected to the first damping pulley mechanism 15. The waveform multi-layer spring rebounds upward and stretches. Since the connector 3 can It moves up and down along the installation through hole, so the connecting body 3 will not drive the pulley seat 11 to jump upward, and the pulley 12 will always be in contact with the upper track, so there will be no jump gap between the pulley 12 and the upper track bracket.

When the door leaf falls, the connecting body 3 connected to the first damping pulley mechanism 15 drives the mounting seat 21 and the rotating body 22 to fall back. The mounting seat 21 squeezes the waveform multi-layer spring, and the waveform multi-layer spring buffers the door leaf and prevents the mounting seat from 21 direct collision with the bottom surface of the accommodation hole, in addition, the auxiliary roller on the right side of the bottom surface of the door leaf follows the door leaf back to the lower track;

When the auxiliary roller on the right side of the door leaf follows the door roller and falls back to the lower track, the auxiliary roller on the right side of the door leaf will also collide with the lower track. At this time, the right side of the door leaf will jump up again and fall back, so the corresponding mounting base 21 , the rotating body 22 and the connecting body 3 also follow the door leaf to jump upward and fall again, and the waveform multi-layer spring repeats the same stretching and compressing movement process. Finally, the auxiliary roller on the right side of the bottom of the door leaf falls back to the bottom again. on track.

(2) Push the door leaf left to open. According to the above, the end of the second damping pulley mechanism 16 without the bounce damping device 2 extends beyond the top surface of the door leaf. Therefore, the upper track extends to the outer wall of the left frame. Outside, the part of the outer edge of the upper track on the outer side of the left frame is used to pass the end of the second damping pulley mechanism 16 that is not provided with the bounce damping device 2, so that the left side of the door leaf can fit with the inner wall of the left frame. ;

When the door leaf is pushed to the left to open, the two damping pulley mechanisms follow the door leaf and move to the left. The inner wall surface of the hook groove 9 of the movable block 52 at the left end of the second damping pulley mechanism 16 abuts the side surface of the boss of the left stop block 17. The movable block 52 at the left end of the second damping pulley mechanism 16 is detached from the slot 8, and the opening of the hook groove 9 of the movable block 52 at the left end of the second damping pulley mechanism 16 rotates upward and is in an upward opening state. At this time, the left The boss of the stopper 17 is completely engaged in the hook groove 9 of the movable block 52 at the left end of the second damping pulley mechanism 16. The door leaf continues to move to the left, and the movable block 52 at the left end of the second damping pulley mechanism 16 moves along the sliding groove 7 Sliding to the right, the damping tube 53 of the second damping pulley mechanism 16 shrinks and dampens and decelerates the door leaf. At this time, the tension spring 54 of the second damping pulley mechanism 16 will also shrink. When the damping tube 53 of the second damping pulley mechanism 16 Completely retracted, the left side wall of the door leaf just fits the inner wall of the left frame, and the door leaf is completely opened at this time;

Since the left side wall of the door leaf and the inner wall of the left frame are in contact, a collision will occur, and the left end of the door leaf will jump upward. At this time, the jump damping device 2 of the second damping pulley mechanism 16 and the first damping pulley mechanism 15 will The principle of the shock device 2 is the same as that of the left end of the door leaf to eliminate the runout gap and reduce the runout shock;

Referring to Figure 4, when the door leaf is pushed to the right to close the door, the boss of the right stopper 17 is engaged in the hook groove 9 of the movable block 52 at the right end of the first damping pulley mechanism 15. Therefore, when the door leaf is pushed to the left to open, due to the first The damping pulley mechanism 15 moves to the left along with the door leaf, which means that the movable block 52 at the right end of the first damping pulley mechanism 15 slides to the right under the pull of the right stopper 17, so the damping tube 53 of the first damping pulley mechanism 15 is re-positioned. Stretch and stretch. At this time, the tension spring 54 of the first damping pulley mechanism 15 is stretched again. Finally, because the slot 8 is bent downward, the movable block 52 on the right end of the first damping pulley mechanism 15 follows the slider. It tilts downward and is locked in the slot 8. At this time, the opening of the hooking groove 9 of the movable block 52 at the right end of the first damping pulley mechanism 15 is in the outward and obliquely upward state again, and the outer wall of the hooking groove 9 The highest point is lower than the bottom surface of the boss of the stopper 17, so the boss of the right stopper 17 is separated from the hook groove 9 of the movable block 52 at the right end of the first damping pulley mechanism 15, so the right stopper 17 is not aligned with the door leaf. Movement to the left causes a block.

In the same way, when the door leaf is pushed to the right to close again, the hook groove 9 of the movable block 52 at the left end of the second damping pulley mechanism 16 and the boss of the left stopper 17 are also disengaged as above.

It should be noted that since the rotating body 22 can rotate in the mounting base 21, during the pushing and pulling process of the door leaf, when the door leaf swings slightly along both sides of the track, the connecting body 3 can follow the door leaf to swing accordingly. Adjust to prevent connector 3 from getting stuck.

Embodiment 2

The difference between Embodiment 2 and Embodiment 1 lies in the structure of the elastomer 23;

Referring to Figure 5, the elastic body 23 is an elastic clip 232. In this embodiment, preferably, the elastic clip 232 is an annular elastic clip. The annular elastic clip has a hollow structure with both ends tilted, and the receiving hole is an inverted T shape. , for the convenience of description, the inverted T-shape is divided into an upper hole and a lower hole, and the mounting base 21 and the rotating body 22 are both located in the upper hole;

The installation method of the annular elastic clip is: the annular elastic clip is buckled downward and installed, that is, the annular elastic clip is pushed in from the side of the inverted T-shaped accommodation hole, and the two ends of the annular elastic clip are in contact with the bottom surface of the lower hole. The top of the slope extending to both ends of the annular elastic clip will contact the turning point of the upper hole and the lower hole, and the top surface of the middle part of the annular elastic clip will contact the bottom surface of the mounting base 21, and the top of the connector 3 passes through The installation through hole in the bottom wall of the accommodation hole of the pulley base 11, the annular elastic clamp and the connection through hole in the lower clamp body of the installation base 21 are finally connected to the rotating body 22;

The working principle of the ring elastic clamp is:

In the initial state, due to the gravity of the door leaf, the mounting base 21 is pressed on the annular elastic clip, and the two ends of the annular elastic clip are in a state of being compressed and extending outward;

When one end of the top of the door leaf jumps upward, the door leaf drives the mounting base 21 and the rotating body 22 through the connecting body 3 to jump toward the upper top surface of the accommodating hole. The two ends of the annular elastic clip shrink toward the middle, and the middle part of the annular elastic clip pushes upward. , the auxiliary roller on the bottom corresponding to the jumping end of the door leaf also jumps slightly from the lower track following the door leaf. Similarly, since the connecting body 3 can move up and down along the installation through hole, the connecting body 3 will not drive the pulley seat 11 to jump upward, and then The pulley 12 is always in contact with the upper rail, so there will be no jumping gap between the pulley 12 and the upper rail bracket.

When the door leaf falls, the corresponding connecting body 3 will drive the mounting base 21 and the rotating body 22 to fall back. The mounting base 21 squeezes the annular elastic clip downwards, and the annular elastic clip elastically buffers the door leaf to prevent the mounting base 21 from colliding with the container. Direct collision with the bottom surface of the hole. In addition, the auxiliary roller on the bottom surface of the jumping end of the door leaf follows the door leaf back to the lower track;

When the auxiliary roller on the bottom surface of the door leaf follows the door leaf and falls back to the lower track, the auxiliary roller on the bottom surface of the door leaf follows the door leaf and falls back to the lower track. It will collide with the lower track. At this time, the door leaf will jump upward again. Then it falls back. During this process, the mounting base 21, the rotating body 22 and the connecting body 3 at the corresponding end also follow the door leaf to jump upward and fall back again, while the annular elastic clip repeats the same process of springing up in the middle and pressing down and stretching at both ends. long process. Finally, the auxiliary roller on the bottom surface of the door leaf jumps back to the lower track again.

In the same way, it is conceivable to replace the elastic clip 232 with a spring piece. Similarly, the spring piece is arranged in the receiving hole and below the mounting base 21. The spring piece can realize reciprocating depression and rebound in the vertical direction, which is better. , in order to limit the position of the elastic piece, the middle part of the elastic piece is provided with a through hole for passing through the connecting body 3. The top of the connecting body 3 passes through the through hole and is connected to the rotating body 22. The connecting body 3 is used to pass through the through hole. way to limit the position of the shrapnel, effectively preventing the deflection of the shrapnel.
