Description

Technical Field

[0001] This utility model relates to the field of deceleration device technology, and in particular to a pivot deceleration device and a rotating door. Background Technology

[0002] In existing product coating processes, products are placed inside a rotating door for coating. The rotating door opens and closes horizontally. When placing products inside the rotating door for coating, workers can only open and close the door manually, making it difficult to control the opening and closing speed. In addition, the door is relatively heavy, resulting in a large airflow when the door is opened and closed. This causes a large airflow inside the rotating door, disturbing the dust inside or outside the rotating door cavity. Therefore, there is an urgent need for a pivot deceleration device that can reduce the opening and closing speed of the rotating door. Utility Model Content

[0003] The purpose of this utility model is to provide a pivoting deceleration device and a rotating door to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] In one aspect, this application provides a pivoting deceleration device.

[0006] A pivoting deceleration device, comprising:

[0007] Mounting base, wherein the mounting base is provided with a slot;

[0008] A damping structure includes a connecting seat and a damping part. The connecting seat is disposed at one end of the mounting base, with the direction from the mounting base to the connecting seat as a first direction. The damping part can move and be positioned on the connecting seat along a direction close to or away from the mounting base. The mounting base has a slot, and the damping part abuts against the mounting base. The connecting seat can rotate relative to the mounting base about a straight line parallel to the first direction. The connecting seat can drive the damping part to rotate relative to the mounting base, so that the damping part engages with or disengages from the slot. The damping part can abut against the side wall of the slot.

[0009] This technical solution has at least the following beneficial effects: The mounting base of the pivot deceleration device is installed on the door seat of the revolving door, and the connecting base is installed on the door shaft of the revolving door. When the coating operation begins, the worker closes the door by manually pushing it closed. At this time, the door rotates around the shaft. When it rotates a certain distance, the damping part moves with the connecting base to the top of the slot. The damping part can always move closer to the mounting base, thus engaging in the slot. The door continues to rotate, and the damping part abuts against the side wall of the slot along the rotation direction of the shaft, thus creating resistance to the door's rotation and decelerating it. This reduces the speed of the door when it reaches its final destination, ultimately reducing the airflow disturbance at the door seat and minimizing the impact on dust inside the door seat.

[0010] As a further improvement to the above technical solution, the connecting seat is provided with a plurality of damping parts evenly spaced along the straight line of the first direction, and the mounting seat is provided with a plurality of slots evenly spaced along the straight line of the first direction, and each damping part can be engaged with any of the slots.

[0011] By adopting the above technical solution, multiple damping parts are set on the connecting seat. By increasing the number of parts, the resistance between the connecting seat and the mounting seat is increased, thereby enhancing the deceleration effect on the door body and greatly reducing the degree of disturbance of the airflow at the door seat by the door body, thus reducing the negative impact on ions at the door seat.

[0012] As a further improvement to the above technical solution, the slot includes a first locking segment, a sliding segment and a second locking segment arranged circumferentially along the straight line of the first direction, and the damping part can move to abut against the end sidewall of the first locking segment or the second locking segment.

[0013] By setting a sliding section, the damping part is not restricted by the slot at the sliding section. Furthermore, when the door is fully closed, the damping part is completely located within the sliding section. At this time, the damping part can slide freely within the slot, thereby avoiding the damping and deceleration effect of the damping part on the door when it is fully closed, allowing the worker to open the door smoothly.

[0014] As a further improvement to the above technical solution, the length of the sliding section is greater than the length of the damping part in the same direction, and the depth of the sliding section is greater than the maximum moving distance of the damping part.

[0015] As a further improvement to the above technical solution, the end of the damping part away from the connecting seat is a spherical surface, the slot extends circumferentially along the straight line of the first direction, and the ends of the first locking segment and the second locking segment that are far apart from each other are both inner arc surfaces, and the spherical surface can abut against the inner arc surface.

[0016] The curved design creates a guide at the end of the slot. When the damping part moves and exits the slot, it abuts against the inner curved surface of the slot. Under the action of the inner curved surface, the damping part moves away from the mounting base, thus smoothly exiting the slot and moving to be flush with the surface of the mounting base. This reduces the jamming caused by the damping part when moving on the mounting base, allowing the door to move smoothly on the door seat.

[0017] As a further improvement to the above technical solution, the damping structure is provided at both ends of the mounting base along the first direction. By providing damping structures on both sides of the mounting base, the stability of the door deceleration is improved, thereby enhancing the uniformity of ions in the door seat when the door opens and closes.

[0018] Secondly, this application provides a revolving door.

[0019] A revolving door includes a door seat, a door body, and the aforementioned pivoting deceleration device. The door body is provided with a rotating shaft extending in a first direction. The rotating shaft is rotatable relative to the door seat. A connecting seat is mounted on the rotating shaft, and a mounting seat is mounted on the door seat.

[0020] By adopting the above technical solution, the pivot deceleration device gradually slows down the door body as it rotates around the pivot axis, reducing the excessive airflow that would disturb the dust in the door seat when the door body moves too fast and closes, thus reducing the impact on the dust inside the door seat.

[0021] As a further improvement to the above technical solution, a sliding seat is provided on the door seat, the sliding seat is detachably connected to the mounting seat, a clamping channel is formed between the sliding seat and the mounting seat, and the rotating shaft is located in the clamping channel.

[0022] By adopting the above technical solution, the sliding seat and the mounting seat are combined to clamp the rotating shaft, which further improves the relative stability between the mounting seat and the rotating shaft, thereby improving the relative stability between the mounting seat and the connecting seat on the rotating shaft.

[0023] As a further improvement to the above technical solution, the mounting base includes a first frame and a second frame that are detachably connected to each other. Both the first frame and the second frame are provided with the slot. An installation channel extending along a first direction is formed between the first frame and the second frame, and the rotating shaft is installed in the installation channel.

[0024] To facilitate the installation of pivot speed reducers on revolving doors, or the replacement of existing pivot speed reducers with different specifications, directly mounting the integrated mounting base onto the rotating shaft requires disassembling the door body to remove the mounting base, which is time-consuming and labor-intensive. The above-mentioned technical solution divides the mounting base into a first frame and a second frame, allowing direct installation on existing revolving doors. First, the first frame is connected to the door seat, then the second frame is mounted on the rotating shaft and connected to the first frame, thus placing the rotating shaft within the installation channel. This solution offers two advantages: First, when disassembling the mounting base, the first and second frames can be quickly disassembled to separate the mounting base from the rotating shaft, reducing disassembly time. Second, by placing the rotating shaft within the mounting base, the connection stability between the mounting base and the door body is improved, resulting in a more stable connection between the mounting base and the door body, allowing the damping part to be stably inserted into the slot, thus improving deceleration stability.

[0025] As a further improvement to the above technical solution, the connecting seat includes a third frame and a fourth frame that are detachably connected to each other, with an installation gap formed between the third frame and the fourth frame, the rotating shaft being installed in the installation gap, and the damping part being provided on both the third frame and the fourth frame.

[0026] By adopting the above technical solution, when installing the connecting seat, the third and fourth frames are placed on both sides of the rotating shaft and fitted onto the rotating shaft, thereby clamping the rotating shaft together with the third and fourth frames. This assembly method has a simple structure and is easy to implement. Attached Figure Description

[0043] In one aspect, embodiments of this application provide a pivoting deceleration device that can be applied to doors with exposed pivot shafts. Specifically, the pivoting deceleration device is applied to the door of a coating machine.

[0044] Existing coating machines are quite heavy, with the door 4 weighing up to one ton and having a large inertia. Therefore, when the door 4 closes, it may have a large speed. Moreover, because the door 4 is too heavy, it is difficult to adjust manually. When the door 4 closes quickly, it will generate airflow, which will disturb the dust inside the coating machine. Therefore, a pivoting deceleration device that can decelerate the door 4 needs to be installed on the reducer.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The present application provides a pivot deceleration device, which includes a mounting base 1 and a damping structure 2. The mounting base 1 is fixedly connected to the door seat 3 of the coating machine, and the damping structure 2 is fixedly installed on the rotation shaft 41 of the door body 4 of the coating machine and can rotate with the rotation shaft 41. The door body 4 is decelerated by the resistance generated between the damping structure 2 and the mounting base 1 in the opposite direction to the movement direction of the door body 4 when the door body 4 rotates.

[0046] Specifically, taking the direction from the mounting base 1 to the connecting base 21 as the first direction, the rotation axis 41 is parallel to the first direction in both its rotation direction and length direction. The damping structure 2 includes the connecting base 21 and the damping part 23. The connecting base 21 is disposed at the end of the mounting base 1 along the first direction. The damping part 23 can move and be positioned on the connecting base 21 along the direction close to or away from the mounting base 1. The mounting base 1 has a slot 11 at the end along the first direction. The slot 11 extends horizontally along the rotation direction of the rotating shaft 41. The connecting base 21 can rotate with the rotating shaft 41 relative to the mounting base 1 with a straight line parallel to the first direction as the axis of rotation. During the rotation of the connecting base 21, the damping part 23 always abuts against the mounting base 1. The connecting base 21 can drive the damping part 23 to rotate relative to the mounting base 1, so that the damping part 23 engages or disengages from the slot 11. The damping part 23 can abut against the side wall of the slot 22.

[0047] In this embodiment, the damping structure 2 further includes a damping element 22 and a damping part 23, which is the end of the damping element 22. For example, the damping element 22 can be a heavy-duty universal ball, and the damping part 23 can be a steel ball of the heavy-duty universal ball. The outer shell of the heavy-duty universal ball is fixedly installed on the connecting seat 21. Under the action of the spring 231 of the heavy-duty universal ball, the steel ball always moves towards the mounting seat 1. The steel ball can always abut against the outer surface of the mounting seat 1 at the non-slot 11 location and the side wall of the end of the slot 11. When the steel ball abuts against the side wall of the end of the slot 11, an interaction force is generated between the two, thereby generating a force on the door 4 opposite to the rotation direction of the door 4.

[0048] As described above, the mounting base 1 of the pivot deceleration device is installed on the door seat 3 of the coating machine, and the connecting seat 21 is installed on the rotating shaft of the door body 4 of the coating machine. When the coating operation begins, the worker closes the door body 4 by manually pushing it closed. At this time, the door body 4 rotates around the rotating shaft. When it rotates to a certain distance, the damping part 23 moves with the connecting seat 21 to the top of the slot 11. The damping part 23 can always move towards the mounting base 1, thus moving to be engaged in the slot 11. At this time, the door body 4 continues to rotate, and the damping part 23 abuts against the side wall of the slot 11 along the rotation direction of the rotating shaft, thereby forming resistance to the rotation of the door body 4, causing the door body 4 to decelerate, so that the speed of the door body 4 when it finally reaches the end point of movement is reduced, ultimately reducing the airflow disturbance of the door body 4 at the door seat 3 and reducing the impact on the dust inside the door seat 3.

[0049] Reference Figure 3 The connecting seat 21 is provided with a plurality of damping parts 23 evenly spaced along the straight line of the first direction, that is, a plurality of damping elements 22 are provided on the connecting seat 21. The mounting seat 1 is provided with a plurality of slots 11 evenly spaced along the straight line of the first direction. After the connecting seat 21 is rotated, each damping part 23 can be engaged in any of the slots 11.

[0050] By setting multiple damping parts 23 on the connecting seat 21, the blocking effect between the connecting seat 21 and the mounting seat 1 is improved. Moreover, when the door body 4 rotates at any angle, each damping part 23 can achieve the deceleration effect on the door body 4, which greatly reduces the degree of disturbance of the airflow at the door seat 3 by the door body 4, thereby reducing the negative impact on the ions at the door seat 3.

[0051] Reference Figure 4 , Figure 5 and Figure 6 The slot 11 includes a first locking section 12, a sliding section 13 and a second locking section 14 arranged sequentially along the circumference of the straight line of the first direction. The damping part 23 can move to abut against the end side wall of the first locking section 12 or the second locking section 14.

[0052] The length of the sliding section 13 is not less than the length of the damping part 23 in the same direction, that is, the length of the sliding section 13 is greater than the diameter of the steel ball of the damping member 22, and the depth of the sliding section 13 is greater than the maximum moving distance of the damping part 23. By setting the sliding section 13, the damping part 23 is not restricted by the slot 11 at the sliding section 13. Furthermore, when the door 4 is in a fully closed state, the damping part 23 is completely located in the sliding section 13. At this time, the damping part 23 can slide freely in the slot 11, thereby avoiding the damping and deceleration effect of the damping part 23 on the door 4 when the door 4 is fully closed, so that the worker can open the door 4 smoothly.

[0053] Specifically, refer to Figure 5 and Figure 6 In this embodiment, there are 6 damping parts 23 and 12 slots 11. On the end plane of the mounting bracket along the first direction, the included angle B between the end of one slot 11 and the end of another slot 11 is 30 degrees, the included angle C of the sliding section 13 is 10 degrees, and the included angle of the projection of the damping part 23 on the same end plane is 10 degrees, so that the damping part 23 can slide freely in the slot 11.

[0054] If the damping part 23 directly abuts against the side wall of the slot 11 in the initial state, the worker will find it difficult to move the door 4 and will be unable to make any initial movement. Therefore, referring to... Figure 6 and Figure 7 When the door 4 is in the closed state, the connecting frame installed on the rotating shaft 41 is in a stationary state. At this time, the damping parts 23 on the connecting frame are all engaged in the slot 11 and located in the sliding section 13 of the slot 11. That is, the damping parts 23 have a certain rotation angle in the slot 11. After the damping parts 23 rotate with the rotating shaft 41, they can make initial sliding in the locking section. This method allows the damping parts 23 to have an acceleration path when the door 4 starts to rotate. Finally, after rotating with the rotating shaft 41, they have an initial velocity that can overcome the obstruction of the side wall of the slot 11, allowing the worker to open the door 4 smoothly.

[0055] Reference Figure 4 The end of the damping part 23 away from the connecting seat 21 is a spherical surface. The slot 11 extends circumferentially along the straight line of the first direction. The ends of the first locking segment 12 and the second locking segment 14 that are far apart from each other are inner arc surfaces. The inner arc surface can abut against the spherical surface. Through the design of the arc surface, a guide is formed at the end of the slot wall of the slot 11. When the damping part 23 moves and exits from the slot 11, it abuts against the inner arc surface of the slot 11, so that the damping part 23 moves away from the mounting seat 1 under the action of the inner arc surface, thereby smoothly exiting the slot 11 and moving to be flush with the surface of the mounting seat 1, reducing the jamming caused by the damping part 23 when moving on the mounting seat 1, so that the door body 4 can move smoothly on the door seat 3.

[0056] Specifically, the sliding section 13 has a first transition arc at both ends along its extension direction. The radius of the first transition arc is equal to the radius of the steel ball of the damping element 22. The first locking section 12 or the second locking section 14 has a second transition arc at the end away from the sliding section 13. The radius of the second transition arc is smaller than the radius of the steel ball of the damping element 22.

[0057] Reference Figure 1 The mounting base 1 has damping structures 2 at both ends along the first direction, and slots 11 are provided at both ends along the first direction. By providing damping structures 2 on both sides of the mounting base 1, the stability of the door body 4 during deceleration is improved.

[0058] Secondly, this application also provides a revolving door.

[0059] Reference Figure 8 and Figure 9 The revolving door includes a door seat 3, a door body 4, and a pivoting deceleration device as described in the first aspect. The door body 4 is provided with a rotating shaft 41 extending in a first direction. The rotating shaft is rotatably mounted on the door seat 3. A connecting seat 21 is mounted on the rotating shaft, and a mounting seat 1 is mounted on the door seat 3. The pivoting deceleration device causes the door body 4 to gradually decelerate as it rotates around the rotating shaft 41, thereby reducing the excessive airflow that would disturb the dust in the door seat 3 when the door body 4 moves too fast and closes.

[0060] Reference Figure 1 and Figure 8 A sliding seat 6 is provided on the door seat 3. The sliding seat 6 is made of Teflon. The sliding seat 6 can be detachably connected to the mounting seat 1. A clamping channel is formed between the sliding seat 6 and the mounting seat 1. The clamping channel is connected to the mounting channel. The rotating shaft 41 is located in the clamping channel. By combining the sliding seat 6 and the mounting seat 1, the rotating shaft 41 of the door body 4 is clamped, which further improves the relative stability between the mounting seat 1 and the rotating shaft 41, thereby improving the relative stability between the mounting seat 1 and the connecting seat 21 on the rotating shaft 41.

[0061] Specifically, refer to Figure 2 and Figure 3 There are two second frames 16, which are respectively installed at both ends of the first frame 15 along the first direction. The sum of the lengths of the two second frames 16 in the first direction is less than the length of the first frame 15 in the first direction. A fixed seat is provided on the door seat 3. An elastic buffer pad 7 and a sliding seat 6 are arranged in sequence on the side of the fixed seat away from the door seat 3. The sliding seat 6 has good wear resistance. The side of the sliding seat 6 away from the door seat 3 is an inner arc surface. The inner arc surface of the sliding seat 6 abuts against the rotation shaft 41 of the door body 4. The sliding seat 6 is fixedly connected to the middle of the first frame 15 located on the side of the rotation shaft 41 away from the frame body by bolts.

[0062] The elastic buffer pad 7 and the sliding seat 6 form an elastic connection between the first frame 15 and the door seat 3, so that when the door 4 rotates, the sliding seat 6 and the mounting seat 1 can have more buffer space as a whole, so as to prevent the sliding seat 6 from being damaged due to excessive force when the rotating shaft 41 of the door 4 is too rubbed against the mounting frame.

[0063] Reference Figure 2 The mounting base 1 includes a first frame 15 and a second frame 16 that are detachably connected to each other. Both the first frame 15 and the second frame 16 are provided with slots 11, and an installation channel extending in a first direction is formed between the first frame 15 and the second frame 16.

[0064] Specifically, the first frame 15 is installed on the side of the rotating rod of the door seat 3 away from the door seat 3, and the second frame 16 is installed on the side of the rotating rod close to the door seat 3. The first frame 15 and the second frame 16 are locked together by bolts, and the first frame 15 is fixedly connected to the door seat 3.

[0065] As described above, in order to facilitate the installation of a pivoting deceleration device on a revolving door, or to replace an existing pivoting deceleration device with one of different specifications after disassembling it, directly mounting the integrated mounting base 1 onto the rotating shaft 41 would require removing the door body 4 to remove the mounting base 1, which is time-consuming and labor-intensive. Through the above technical solution, the mounting base 1 is divided into a first frame 15 and a second frame 16, allowing direct installation on existing revolving doors. First, the first frame 15 is connected to the door seat 3, then the second frame 16 is mounted on the rotating shaft 41 and connected to the first frame 15. A frame 15 is used to fit the rotating shaft 41 into the installation channel. With this solution, firstly, when it is necessary to disassemble or assemble the mounting base 1, the mounting base 1 and the rotating shaft 41 can be quickly separated by disassembling the first frame 15 and the second frame 16, reducing the time required for disassembly and assembly. Secondly, the rotating shaft 41 can be set inside the mounting base 1, and the connection stability between the mounting base 1 and the door body 4 can be improved by fitting them together. This makes the connecting seat 21 on the mounting base 1 and the door body 4 relatively stable, so that the damping part 23 can be stably inserted into the slot 11, improving the deceleration stability.

[0066] Furthermore, refer to Figure 3 and Figure 9 Both the first frame 15 and the second frame 16 are provided with ball head preload screws 17 on the side near the rotating shaft 41 of the door body 4. The ball head of the ball head preload screw 17 can abut against the rotating shaft 41 of the door body 4 and can rotate relative to the rotating shaft 41, which reduces the sliding friction between the first frame 15 and the second frame 16 and the rotating shaft 41 and converts it into the rolling friction of the ball head preload screw, which reduces the friction between the mounting base 1 as a whole and the rotating shaft 41, making the relative rotation between the mounting base 1 and the rotating shaft 41 smoother.

[0067] Reference Figure 3The connecting seat 21 includes a third frame 24 and a fourth frame 25 that are detachably connected to each other. An installation gap is formed between the third frame 24 and the fourth frame 25. Both the third frame 24 and the fourth frame 25 are provided with damping parts 23.

[0068] By adopting the above technical solution, when installing the connecting seat 21, the third frame 24 and the fourth frame 25 are directly placed on both sides of the rotating shaft 41 and sleeved on the rotating shaft 41, so that the third frame 24 and the fourth frame 25 together clamp the rotating shaft 41. This assembly method has a simple structure and is easy to implement.

[0069] To align and correct the damping parts 23 and the slots 11 after the pivoting deceleration device is installed, so that each damping part 23 can accurately fall into the slot 11 after rotation, refer to... Figure 1 The connector 21 is provided with at least one pair of positioning pins 5, and each positioning pin 5 can be detachably inserted into the mounting base 1 at one end protruding from the connector 21.

[0070] In other embodiments, reference is made to Figure 9 The connecting seat 21 is provided with multiple pairs of positioning pins 5 along the circumferential direction. Each pair of two positioning pins 5 can be installed on both the connecting seat 21 and the mounting seat 1 at the same time, thereby enhancing the coaxiality between the connecting seat 21 and the mounting seat 1 and improving the snap-fit ​​accuracy between the slot 11 and the damping part 23.

[0071] As can be seen from the above, when installing the connecting seat 21, first place the connecting seat 21 on the rotating shaft 41, then insert a pair of positioning pins 5 through the connecting seat 21 into the mounting seat 1. At this time, the damping part 23 on the connecting seat 21 and the slot 11 on the mounting seat 1 are directly opposite each other. Finally, fix the connecting seat 21 on the rotating shaft 41 to align the damping part 23 and the slot 11.

[0072] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
