Description

Technical Field

[0001] This invention relates to the field of rivet technology, and in particular to a rivet and its production equipment. Background Technology

[0002] Rivets can be used to hold a connecting plate in place on a fixed plate, so that the distance between the connecting plate and the fixed plate does not change, thereby fixing the object on the connecting plate.

[0003] In existing technologies, most rivets do not have noise reduction capabilities, which causes noise pollution when objects on the connecting plate vibrate. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a rivet and its production equipment to solve the above problems.

[0005] In view of this, the present invention provides a rivet comprising:

[0006] The limiting elastic structure extends from the bottom end through the connecting plate toward the fixed plate; the top end abuts against the end of the connecting plate away from the fixed plate.

[0007] A support structure is disposed within the bottom end of the limiting elastic structure. The support structure is slidable within the limiting elastic structure, and the bottom end of the support structure is flush with the bottom end of the limiting elastic structure.

[0008] The bolt, with its threaded portion extending through the limiting elastic structure toward the fixing plate;

[0009] And the adjusting mechanism, one end of which is connected to the bolt thread and the other end of which is connected to the fixed plate thread;

[0010] When the bolt is threadedly connected to the adjusting mechanism, the rotating part of the bolt abuts against the top of the limiting elastic structure and descends. The limiting elastic structure abuts against the connecting plate and descends. When the limiting elastic structure and the supporting structure abut against the adjusting mechanism, the bolt continues to be threadedly connected until the limiting elastic structure descends and abuts against the supporting structure. The bottom end of the limiting elastic structure wrinkles due to the compression of the adjusting mechanism and abuts against the bottom end of the connecting plate.

[0011] By adopting the above technical solution, when the connecting plate needs to be installed, the adjusting mechanism is first threadedly connected to the fixed plate to fix the adjusting mechanism; then, the bolt is threadedly connected to the adjusting mechanism. At this time, the rotating part of the bolt slowly descends against the top of the limiting elastic structure, while the connecting plate is pressed down by the limiting elastic structure. When the limiting elastic structure and the support structure abut against the top of the adjusting mechanism, the bolt continues to be threadedly connected. At this time, the support structure slowly rises within the limiting elastic structure, and because the distance between the connecting plate and the adjusting mechanism gradually shortens, the bottom end of the limiting elastic structure is compressed and wrinkles appear. At the same time, due to the support structure within the bottom end of the limiting elastic structure, the wrinkles at the bottom end of the limiting elastic structure can only wrinkle outwards. When the bolts of the supporting structure and the limiting elastic structure located above the connecting plate can no longer rotate, the folds at the bottom of the limiting elastic structure abut against the bottom of the connecting plate, and the top of the limiting elastic structure is stably abutted against the top of the connecting plate by the bolts. At this time, the connecting plate is abutted by the limiting elastic structures on both sides. No matter which direction the connecting plate shakes or vibrates, it will be buffered, thereby achieving noise reduction and buffering. The above-mentioned adjusting mechanism can be installed or not. When the adjusting mechanism is not installed, the bolts are directly connected to the fixed plate, which is the same as installing it on the adjusting mechanism, achieving the same effect. By setting the adjusting mechanism, the distance between the connecting plate and the fixed plate can be changed, so that the connecting plate can better achieve the desired height.

[0012] In the above technical solution, the further limiting elastic structure includes:

[0013] An elastic cylindrical block is located at the end of the connecting plate opposite to the fixed plate.

[0014] An abutment ring is provided inside the elastic cylindrical block;

[0015] And a hollow cylindrical elastic tube, one end of which passes through the top of the elastic cylindrical block and is connected, and the other end extends toward the adjusting mechanism.

[0016] The elastic cylindrical block has an annular cavity for placing an abutment ring, the top of the elastic cylindrical block has a placement hole for the abutment ring to pass through and be inserted, and the bottom of the annular cavity has a through hole communicating with the hollow cylindrical elastic tube.

[0017] In this technical solution, the elastic cylindrical block allows the top of the connecting plate to be abutted. The abutting ring allows the bolt to press against the abutting ring, which in turn presses against the elastic cylindrical block, making the elastic cylindrical block abutting the connecting plate more stable. The hollow cylindrical elastic tube allows folds to form as the distance between the connecting plate and the adjusting mechanism approaches, and the folds abut against the bottom of the connecting plate to form a buffer.

[0018] In the above technical solution, the further supporting structure includes:

[0019] The first contact part has its outer wall abutting against the inner wall of the hollow cylindrical elastic tube, and the bottom end of the first contact part is flush with the bottom opening of the hollow cylindrical elastic tube.

[0020] The anti-wrinkle contact part is connected to the top of the first contact part, and the outer wall of the anti-wrinkle contact part abuts against the inner wall of the hollow cylindrical elastic tube.

[0021] The connecting part is connected to the top of the anti-wrinkle contact part, and the outer wall of the connecting part abuts against the inner wall of the hollow cylindrical elastic tube.

[0022] The pleated part is connected to the top of the connecting part, and the outer wall of the pleated part slides and abuts against the inner wall of the hollow cylindrical elastic tube.

[0023] And a second contact portion, connected to the top of the pleated portion, and the outer wall of the second contact portion abuts against the inner wall of the hollow cylindrical elastic tube;

[0024] Wherein, the initial position of the top of the second contact part is lower than that of the connecting plate. When the hollow cylindrical elastic tube is compressed, the pleated part is used to make the upper part of the hollow cylindrical elastic tube pleated first. The anti-pleating contact part is used to prevent the hollow cylindrical elastic tube from pleating and to contact the bottom end of the pleated part of the hollow cylindrical elastic tube. The pleated part and the anti-pleating contact part are both hollow cylindrical pleated structures.

[0025] In this technical solution, the pleated portion allows relative movement between the hollow cylindrical elastic tube and the pleated portion when the tube is compressed. Due to the contact of the pleated portion, the hollow cylindrical elastic tube pleats according to its height. When the second contacting part contacts the contact ring, the pleated portion is located within the connecting plate. At this time, the contacting part presses against the wall of the hollow cylindrical elastic tube, generating a clamping force on the inner wall of the connecting plate. Simultaneously, the pleated portion of the hollow cylindrical elastic tube contacts the bottom end of the connecting plate. Through the provision of the anti-wrinkle contacting part, when… When the hollow cylindrical elastic tube is compressed, the bottom end of the hollow cylindrical elastic tube and the first contact part both abut against the top of the adjusting mechanism. Since the anti-wrinkle contact part is located at the bottom, the hollow cylindrical elastic tube will not move relative to the anti-wrinkle contact part at first. As a result, after the upper part of the hollow cylindrical elastic tube wrinkles, it will abut against the anti-wrinkle contact part. Through the setting of the first contact part and the second contact part, the contact ring can be restricted from continuing to descend or rise. Thus, the rising and falling of the connecting plate will be restricted by the limiting elastic structure.

[0026] In the above technical solution, the further adjusting mechanism includes:

[0027] The threaded rod has one end threadedly connected to the fixed plate, and the other end extends toward the limiting elastic structure.

[0028] A support block is connected to the end of the threaded rod away from the fixed plate, and the top of the support block is provided with a sliding groove;

[0029] The connecting block is inserted into the groove, and the top center of the connecting block is threaded with the bolt. The top edge is used to abut against the hollow cylindrical elastic tube and the first abutting part.

[0030] A limiting structure is provided on the connecting block and the support block;

[0031] The limiting structure is used to control whether the connecting block can rotate and descend within the slide groove.

[0032] In this technical solution, the threaded rod can fix the support block, the cooperation between the support block and the slide groove can place the connecting block, the connecting block can connect the bolts, and the bottom of the support structure and the limiting elastic structure can be supported. The limiting structure does not restrict the connecting block. When disassembling the connecting plate and the fixing plate, the support block can be rotated to release the threaded connection of the threaded rod. The support block rises, and the connecting block rotates and falls along the slide groove, keeping the connecting plate in a horizontal position at all times. This prevents the connecting plate from breaking other rivets when removing one rivet, and provides convenience for reinstalling the connecting plate.

[0033] In the above technical solution, the further limiting structure includes:

[0034] Two insertion slots are respectively provided on the two side walls of the connecting block;

[0035] Two limiting rods are set at the bottom of the insertion slot;

[0036] Two limiting blocks, one end of which is inserted into the limiting rod, and the other end of which is inserted into the inner wall of the support block;

[0037] Two first elastic members are connected at one end to the bottom of the insertion slot and at the other end to the end of the limiting block facing the insertion slot;

[0038] The fixing ring is fitted onto the outer wall of the support block;

[0039] And a push rod, one end of which is located outside the fixed ring, and the other end passes through the fixed ring, the support block and abuts against the limit block;

[0040] The support block is provided with a limiting hole for the push rod and the limiting block to pass through, and the fixing ring and the push rod are provided with a second elastic element for the push rod to rebound.

[0041] In this technical solution, the insertion slot allows the limiting rod to be installed, which in turn enables the limiting block to move more stably. The first elastic element ensures that the limiting block is always in an outward-extending state. The fixing ring allows the push rod to be installed. The limiting hole restricts the movement of the limiting block into the limiting hole, and the push rod can move into the limiting hole to push the limiting block into the sliding groove, thereby releasing the restriction. The second elastic element allows the push rod to automatically rebound.

[0042] The above technical solution further includes a corrugating device for producing the support structure.

[0043] In this technical solution, the creasing device enables the support structure to have a creasing part and an anti-creasing contact part.

[0044] In the above technical solution, the further wrinkling device includes:

[0045] A working block, the top of which is provided with a working disc, the top of which is provided with a plurality of placement slots, and the inner wall of the placement slots is provided with two folding slots for folding at intervals;

[0046] The carrier is set on the working block;

[0047] The hydraulic cylinder has its fixed end located at the top of the carrier frame, and its output end extends through the carrier frame toward the working plate.

[0048] The mounting plate is connected to the output end of the hydraulic cylinder at one end and extends towards the working plate at the other end.

[0049] And several crimping mechanisms, one end of which is connected to the bottom of the mounting plate, and the other end of which is set directly opposite the placement slot;

[0050] The placement groove is used to place the processing materials for the support structure.

[0051] In this technical solution, the working block enables the installation of the working disc, the two folding grooves enable the processing material of the support structure to fold into folded parts and anti-folding contact parts, the carrier enables the installation of the hydraulic cylinder, the hydraulic cylinder enables the installation disc to automatically descend and rise, and the cooperation of several folding mechanisms and several placement grooves enables multiple support structures to be processed at one time when the installation disc descends.

[0052] In the above technical solution, the further wrinkling mechanism includes:

[0053] The drive rod is connected to the work plate at one end and extends toward the placement slot at the other end;

[0054] A pressure block is inserted into a drive rod, and the pressure block is provided with a movable groove for the drive rod to be inserted into;

[0055] The pressure ring is fitted onto the outer wall of the pressure block;

[0056] The driving rod has one end connected to the inner wall of the pressure ring, and the other end extends into the moving groove and is connected to the driving rod.

[0057] It also has two abutting structures, with the output end spaced apart on the outer wall of the pressure block, and the input end extending into the moving groove to cooperate with the drive rod;

[0058] The drive rod has two drive grooves on its outer side wall for driving the input end of the abutment structure. The two abutment structures are located below the pressure ring. The pressure block has a sliding hole for the drive rod to slide. The bottom of the moving groove has a third elastic element for the rebound drive rod.

[0059] In this technical solution, the pressure block is inserted into the inner wall of the support structure. The pressure ring and sliding hole allow the pressure ring to press against the top of the material being processed in the support structure when the drive rod descends. The cooperation between the drive rod and the drive groove allows the two contacting structures to extend outwards from the pressure block when the drive rod descends. Simultaneously, the pressure ring presses against the top of the material being processed in the support structure due to the descending drive rod. Under the pressure at the top of the material and the pushing of the contacting structures against the inner wall of the material, the support structure is completely folded within the folding groove, preventing irregular folds and greatly improving the production stability of the support structure. The third elastic element allows relative movement between the pressure block and the drive rod after processing.

[0060] In the above technical solution, the further resisting structure includes:

[0061] An annular groove is provided on the outer wall of the pressure block, and the bottom of the annular groove is provided with two movable holes that communicate with the movable groove.

[0062] The movable rod has one end engaged with the drive groove of the drive rod, and the other end slidably within the movable hole and the annular groove through the drive groove.

[0063] The folding plate has its inner wall located at the end of the moving rod opposite to the drive groove.

[0064] The push-cord plate is pushed out of the annular groove by a moving rod, and the inner wall of the moving hole is provided with a spring-back structure for the spring-back moving rod.

[0065] In this technical solution, the moving rod and the drive groove cooperate to move the moving rod in the moving hole and the annular groove, thereby pushing the crease plate out of the annular groove and pressing it against the inner wall of the support structure. With the setting of the spring structure, when the drive rod rises, the moving rod automatically springs back and brings back the crease plate, thereby moving the pressure block out of the placement groove.

[0066] The beneficial effects of this invention are:

[0067] 1. Through the limiting elastic structure, support structure and bolts, the connecting plate can be stably supported on the fixed plate, and the noise reduction effect is achieved.

[0068] 2. The distance between the connecting plate and the fixed plate can be increased by setting the distance adjustment mechanism.

[0069] 3. The crimping device enables more stable and faster production of the support structure. Attached Figure Description

For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

[0083] Example 1:

[0084] This embodiment provides a rivet, including:

[0085] The limiting elastic structure extends from the bottom end through the connecting plate 1 toward the fixing plate 2; the top end abuts against the end of the connecting plate 1 that is away from the fixing plate 2.

[0086] A support structure is disposed within the bottom end of the limiting elastic structure. The support structure is slidable within the limiting elastic structure, and the bottom end of the support structure is flush with the bottom end of the limiting elastic structure.

[0087] Bolt 3, with its threaded portion extending through the limiting elastic structure toward the fixing plate 2;

[0088] And the adjusting mechanism, one end of which is connected to the threaded part of the bolt 3, and the other end is connected to the threaded part of the fixing plate 2;

[0089] When the bolt 3 is threadedly connected to the adjusting mechanism, the rotating part of the bolt 3 abuts against the top of the limiting elastic structure and descends, and the limiting elastic structure abuts against the connecting plate 1 and descends. When the limiting elastic structure and the support structure abut against the adjusting mechanism, the bolt 3 continues to be threadedly connected until the limiting elastic structure descends and abuts against the support structure. The bottom end of the limiting elastic structure wrinkles due to the compression of the adjusting mechanism and abuts against the bottom end of the connecting plate 1.

[0090] When connecting plate 1 needs to be installed, first connect the adjusting mechanism to the fixed plate 2 by thread to fix the adjusting mechanism; then connect bolt 3 to the adjusting mechanism by thread. At this time, the rotating part of bolt 3 slowly descends against the top of the limiting elastic structure, and the connecting plate 1 is pressed down by the limiting elastic structure. When the limiting elastic structure and the support structure abut against the top of the adjusting mechanism, bolt 3 continues to be threaded. At this time, the support structure slowly rises within the limiting elastic structure, and because the distance between connecting plate 1 and the adjusting mechanism gradually shortens, the bottom end of the limiting elastic structure is compressed and wrinkles appear. At the same time, because of the support structure inside the bottom end of the limiting elastic structure, the wrinkles at the bottom end of the limiting elastic structure can only wrinkle outwards. When the limiting elastic structure above the connecting plate 1 cannot continue to rotate due to the contact bolt 3, the folds at the bottom of the limiting elastic structure abut against the bottom of the connecting plate 1, and the top of the limiting elastic structure is stably abutted against the top of the connecting plate 1 by the bolt 3. At this time, the connecting plate 1 is abutted by the limiting elastic structures on both sides. No matter which direction the connecting plate 1 shakes or vibrates, it will be buffered, thereby achieving noise reduction and buffering. The above-mentioned adjusting mechanism can be installed or not. When the adjusting mechanism is not installed, the bolt 3 is directly connected to the fixed plate 2, which is the same as installing it on the adjusting mechanism, achieving the same effect. By setting the adjusting mechanism, the distance between the connecting plate 1 and the fixed plate 2 can be changed, so that the connecting plate 1 can better achieve the desired height.

[0091] Example 2:

[0092] In this embodiment, in addition to the structural features of the aforementioned embodiments, the further limiting elastic structure includes:

[0093] An elastic cylindrical block 4 is disposed at one end of the connecting plate 1 away from the fixed plate 2;

[0094] The contact ring 5 is disposed inside the elastic cylindrical block 4;

[0095] And a hollow cylindrical elastic tube 6, one end of which passes through the top of the elastic cylindrical block 4 and is connected, and the other end extends toward the adjusting mechanism.

[0096] The elastic cylindrical block 4 has an annular cavity 7 for placing the abutment ring 5, the top of the elastic cylindrical block 4 has a placement hole 8 for the abutment ring 5 to pass through and be inserted, and the bottom of the annular cavity 7 has a through hole 9 that communicates with the hollow cylindrical elastic tube 6.

[0097] By setting the elastic cylindrical block 4, the top of the connecting plate 1 can be abutted. By setting the abutting ring 5, the bolt 3 can be pressed against the abutting ring 5, and the abutting ring 5 can be pressed against the elastic cylindrical block 4, making the elastic cylindrical block 4 abutting the connecting plate 1 more stable. By setting the hollow cylindrical elastic tube 6, wrinkles can be formed as the distance between the connecting plate 1 and the adjusting mechanism approaches, and the wrinkles abut against the bottom of the connecting plate 1 to form abutment buffer.

[0098] Example 3:

[0099] In this embodiment, in addition to the structural features included in the foregoing embodiments, the further supporting structure includes:

[0100] The outer wall of the first contact part 10 abuts against the inner wall of the hollow cylindrical elastic tube 6, and the bottom end of the first contact part 10 is flush with the bottom opening of the hollow cylindrical elastic tube 6.

[0101] The anti-wrinkle contact part 11 is connected to the top of the first contact part 10, and the outer wall of the anti-wrinkle contact part 11 abuts against the inner wall of the hollow cylindrical elastic tube 6.

[0102] The connecting part 12 is connected to the top of the anti-wrinkle contact part 11, and the outer wall of the anti-wrinkle contact part 11 abuts against the inner wall of the hollow cylindrical elastic tube 6.

[0103] The pleated portion 13 is connected to the top of the connecting portion 12, and the outer wall of the pleated portion 13 slides and abuts against the inner wall of the hollow cylindrical elastic tube 6.

[0104] And the second contact portion 14 is connected to the top of the pleated portion 13, and the outer side wall of the second contact portion 14 abuts against the inner wall of the hollow cylindrical elastic tube 6.

[0105] Wherein, the initial position of the top of the second contact part 14 is lower than that of the connecting plate 1. When the hollow cylindrical elastic tube 6 is compressed, the wrinkled part 13 is used to make the upper part of the hollow cylindrical elastic tube 6 wrinkle first. The anti-wrinkle contact part 11 is used to prevent the hollow cylindrical elastic tube 6 from wrinkling and is used to contact the bottom end of the wrinkled part of the hollow cylindrical elastic tube 6. The wrinkled part 13 and the anti-wrinkle contact part 11 are both hollow cylindrical wrinkled structures.

[0106] By providing the pleated portion 13, when the hollow cylindrical elastic tube 6 is compressed, the hollow cylindrical elastic tube 6 and the pleated portion 13 move relative to each other. Due to the contact of the pleated portion 13, the hollow cylindrical elastic tube 6 pleats according to the height of the pleated portion 13. When the second contact portion 14 contacts the contact ring 5, the pleated portion 13 is located inside the connecting plate 1. At this time, the contact portion presses against the wall of the hollow cylindrical elastic tube 6, causing a clamping force on the inner wall of the connecting plate 1. At the same time, the pleated portion of the hollow cylindrical elastic tube 6 contacts the bottom end of the connecting plate 1. By providing the anti-wrinkle contact portion 11, when... When the hollow cylindrical elastic tube 6 is compressed, since the bottom end of the hollow cylindrical elastic tube 6 and the first contact part 10 both abut against the top of the adjusting mechanism, and since the anti-wrinkle contact part 11 is located at a lower position, the hollow cylindrical elastic tube 6 will not initially move relative to the anti-wrinkle contact part 11. As a result, after the upper part of the hollow cylindrical elastic tube 6 wrinkles, it will abut against the anti-wrinkle contact part 11. Through the setting of the first contact part 10 and the second contact part 14, the contact ring 5 can be restricted from continuing to descend or rise. Thus, the rise and fall of the connecting plate 1 will be restricted by the limiting elastic structure.

[0107] Example 4:

[0108] In this embodiment, in addition to the structural features of the aforementioned embodiments, the further adjustable distance mechanism includes:

[0109] The threaded rod 15 has one end threadedly connected to the fixed plate 2, and the other end extends toward the limiting elastic structure.

[0110] A support block 16 is connected to one end of the threaded rod 15 away from the fixed plate 2, and the top of the support block 16 is provided with a sliding groove 18;

[0111] The connecting block 17 is inserted into the slide groove 18, and the top center of the connecting block 17 is threadedly connected to the bolt 3. The top edge is used to abut against the hollow cylindrical elastic tube 6 and the first abutting part 10.

[0112] A limiting structure is provided on the connecting block 17 and the support block 16;

[0113] The limiting structure is used to control whether the connecting block can rotate and descend within the slide groove 18;

[0114] The threaded rod 15 allows the support block 16 to be fixed. The support block 16 and the slide groove 18 allow the connecting block 17 to be placed. The connecting block 17 allows the bolt 3 to be connected and supports the bottom of the support structure and the limiting elastic structure. The limiting structure does not restrict the connecting block 17. When disassembling the connecting plate 1 and the fixing plate 2, the support block 16 can be rotated to release the threaded connection of the threaded rod 15. The support block 16 rises, and the connecting block 17 rotates and descends along the slide groove 18, keeping the connecting plate 1 in a horizontal position. This prevents the connecting plate 1 from breaking one rivet when it is disassembled and provides convenience for reinstalling the connecting plate 1.

[0115] Example 5:

[0116] In this embodiment, in addition to the structural features included in the foregoing embodiments, the further limiting structure includes:

[0117] Two insertion slots 19 are respectively provided on the two side walls of the connecting block 17;

[0118] Two limiting rods 20 are set at the bottom of the insertion slot 19;

[0119] Two limiting blocks 21, one end of which is inserted into the limiting rod 20, and the other end of which is inserted into the inner wall of the support block 16;

[0120] Two first elastic members 22 are connected at one end to the bottom of the insertion groove 19 and at the other end to the end of the limiting block 21 facing the insertion groove 19;

[0121] The fixing ring 23 is fitted onto the outer wall of the support block 16;
