Description

Technical Field

[0001] The present application relates to the technical field of board clips, and in particular to a hovering structure and a board clip, a document booklet or a document folder containing the same. Background Art

[0002] A paper clamp is a document holding tool, whose structure includes a clamp and a plate body connected to the clamp, and the paper and the like are clamped on the plate body by the clamping function of the angle; the current paper clamp structures mainly include conventional paper clamps and suspended paper clamps; among them, the conventional paper clamp rebounds through the double torsion springs inside the clamp, and when clamping paper, one hand is required to pry the clamp away from the plate body to maintain the opening, and the other hand is required to put the document to be clamped into the opening and then release the hand that pried the clamp to tighten the document. Therefore, the operation process requires both hands to operate at the same time, which is not fast enough to use; and the existing suspended board clamp structure, such as a suspended clamp and paper clamp disclosed in ZL202323630802.4, includes a clamp, a torsion spring and a pressing plate, the clamp is directly or indirectly installed on the plate body and can be flipped up and down relative to the plate body, the pressing plate can be installed in the pressing plate opening of the clamp so as to be flipped up and down, the rear side of the clamp is the paper pressing side, and the torsion spring is against the clamp, which is used to press The clamping plate provides a clamping force pressing toward the paper pressing side, and the front side of the clamping plate is a clutch side. The clutch side of the clamping plate is provided with a first protrusion directly or indirectly fixed to the plate body, and a clutch structure is provided between the first protrusion and the front side of the pressing plate, which is used to connect the front side of the pressing plate with the first protrusion and push the rear side out of the pressing plate port when the clutch side of the clamping plate is pressed, and to separate the pressing plate from the first protrusion when the pressing plate is pressed again, and to clamp the paper pressing side under the action of the torsion spring; for this kind of suspended clamping plate, when the clamp is opened, one end of the upper part of the clamp needs to be lifted upward, and the other end is pressed in the opposite direction when closed. Although it can achieve hovering, its hovering position is single and fixed, and cannot be adjusted according to the thickness of the clamped document; in addition, since the hovering position of this structure is single and cannot be changed, the positioning at the same position is mainly achieved by snapping, which can easily cause the paper clamping part of the clamp to fall off and cause failure and damage. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present application provides a hovering structure that can effectively adjust the hovering position according to the thickness of the clamped file.

[0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present application is: a suspension structure, which includes a fixed seat plate and a flip clamp plate that can rotate relative to each other, and a torsion spring is arranged between the fixed seat plate and the flip clamp plate, and the torsion spring is used to drive the flip clamp plate and the fixed seat plate to clamp each other; a ratchet suspension structure is also arranged between the fixed seat plate and the flip clamp plate, and the ratchet suspension structure can be used for the flip clamp plate to flip and hover relative to the fixed seat plate.

[0005] By adopting the above structure, the present application realizes the flipping and hovering of the flipping splint relative to the fixed seat plate through a ratchet suspension structure. Since the ratchet teeth are a helical tooth structure, the meshing angle of the two can be adjusted over a wide range. Therefore, the use of this ratchet suspension structure can realize the flipping and hovering of the flipping splint relative to the fixed seat plate at multiple angles. The suspension angle and position can be flexibly adjusted according to the thickness of the document to be clamped, and the adaptability is stronger.

[0006] Furthermore, the ratchet suspension structure includes a ratchet shaft and a compression spring, the ratchet shaft is provided with a first ratchet tooth, the fixed seat plate or the flip clamp is provided with a second ratchet tooth, the first ratchet tooth is used to engage with the second ratchet tooth, and the compression spring abuts against one end of the ratchet shaft and is used to drive the ratchet shaft to operate axially elastically.

[0007] The first and second ratchet teeth are firmly engaged with each other under the action of the pushing force of the compression spring, so that the flipping plate can be fixed at the flipping angle and hover (that is, the flipping plate is rotated to a certain opening angle relative to the fixed seat plate, and then the angle is fixed by the meshing action of the ratchet teeth). At this time, the opening formed between the fixed seat plate and the flipping plate can be The document is placed inside; then the end of the ratchet shaft is pressed, so that the ratchet shaft runs axially again and pushes the compression spring to compress. In this process, the first ratchet tooth on the ratchet shaft is temporarily separated from the second ratchet tooth provided on the fixed seat plate or the flip clamping plate. At this time, the torsion spring drives the flip clamping plate to close toward the fixed seat plate under the action of its own restoring force to clamp the placed document; the structure of the present application that relies on the engagement of the ratchet teeth to achieve hovering can adjust different hovering positions as needed, and the hovering position is not unique, so it can be suitable for the clamping needs of documents of different thicknesses and flexibly adjust the opening size; moreover, the operation process of the hovering structure of the present application is simple, and only one hand is needed to flip the flip clamping plate, and when clamping, only one hand is needed to press the end of the ratchet shaft, so that the meshing ratchet teeth are temporarily separated from each other and the torsion spring drives the flip clamping plate to reset.

[0008] Furthermore, the flip splint is provided with a second ratchet tooth, and the first ratchet tooth of the ratchet shaft is meshed with the second ratchet tooth through the pushing of the compression spring; with this structure, when the flip splint is flipped relative to the fixed seat plate, the two ratchet teeth push each other, which will drive the ratchet shaft to axially push the compression spring to compress, so that the flip splint can be flipped smoothly. After flipping to the appropriate position, the flipping is stopped. At this time, the compression spring is reset in the reverse direction to push the first ratchet tooth and the second ratchet tooth on the flip splint to engage firmly and achieve hovering.

[0009] Furthermore, a stepped shaft is provided on one side of the fixed seat plate along the length direction, the torsion spring is sleeved on the stepped shaft, the compression spring is located in the axial hole of the stepped shaft, and one end of the ratchet shaft is sleeved in the axial hole of the step shaft and abuts against the compression spring; sleeve sleeves are provided at both ends of the flip splint along the length direction, and the pressing end of the ratchet shaft and one end of the step shaft are respectively sleeved in the corresponding sleeve sleeves at both ends; by adopting this structure, the torsion spring can be limited between the step shaft and the ratchet shaft to prevent it from detaching; and through the sleeve sleeve fitting with the ratchet shaft and one end of the step shaft, the circumferential relative rotation of the flip splint and the fixed seat plate is realized.

[0010] Furthermore, the second ratchet teeth are located on the shaft wall of the fitting sleeve at one end, and the second ratchet teeth extend along the axial direction, and the corresponding first ratchet teeth and second ratchet teeth extend axially relative to each other and engage with each other; by adopting this structure, the axial driving of the ratchet shaft is realized during the flipping process through the engagement of the axial ratchet teeth, which simplifies the structure and saves space.

[0011] Furthermore, a convex rib is axially arranged on the shaft body of the ratchet shaft, and a groove which slidably cooperates with the convex rib is correspondingly arranged in the shaft hole of the step shaft; with this structure, after the ratchet shaft is fitted into the shaft hole of the step shaft, the ratchet shaft is circumferentially limited relative to the fixed seat body through the cooperation of the convex rib and the groove, and only axial relative sliding occurs to each other; this method can make the ratchet shaft rotate without following the circumferential rotation of the flip splint, and the flipping process of the flip splint is more labor-saving, and when flipped to the appropriate position, it can be firmly engaged with the ratchet shaft to achieve hovering.

[0012] Furthermore, the force-applying portion of the flipping splint is provided with anti-skid ribs. With this structure, when force is applied to this portion, the flipping splint is not prone to slipping during the circumferential flipping process relative to the fixed seat body.

[0013] Furthermore, a second ratchet tooth is arranged on the fixed seat body, and the ratchet shaft is sleeved on the flip clamp and is circumferentially limited with the flip clamp, and the first ratchet tooth is pushed and meshed with the second ratchet tooth by the compression spring; with this structure, when the flip clamp is flipped relative to the fixed seat plate, due to the circumferential limitation of the ratchet shaft and the flip clamp, the two are flipped relative to the fixed seat plate synchronously, and in this process, the two ratchet teeth push each other, which will drive the ratchet shaft to axially push the compression spring to compress, so that the flip clamp is flipped smoothly, and after flipping to the appropriate position, the flipping is stopped, at which time the compression spring is reset in the reverse direction to push the first ratchet tooth and the second ratchet tooth on the fixed seat plate to engage firmly and achieve hovering.

[0014] Furthermore, the flip splint is provided with a first sleeve and a second sleeve on one side along its length direction, and the torsion spring is located between the first sleeve and the second sleeve; the compression spring is located in the axial hole of the second sleeve; the ratchet shaft is sleeved in the axial holes of the first sleeve and the second sleeve, and one end thereof abuts against the compression spring; a third sleeve is provided at each end of the fixed seat body along the length direction, and the pressing end of the ratchet shaft and one end of the second sleeve are respectively sleeved in the axial holes of the two third sleeves; by adopting this structure, the torsion spring can be limited between the first sleeve and the second sleeve to prevent it from detaching; and through the sleeve engagement of the third sleeve with the ratchet shaft and one end of the second sleeve, the circumferential relative rotation of the flip splint and the fixed seat plate is realized.

[0015] Furthermore, the second ratchet teeth are located on the end wall of the third shaft sleeve at one end, and the second ratchet teeth extend along the axial direction, and the corresponding first ratchet teeth and second ratchet teeth extend axially relative to each other and engage with each other; by adopting this structure, the axial driving of the ratchet shaft is realized during the flipping process through the engagement of the axial ratchet teeth, which simplifies the structure and saves space.

[0016] Furthermore, a convex rib is axially arranged on the shaft body of the ratchet shaft, and a sliding groove slidably matched with the convex rib is correspondingly arranged in the axial holes of the first sleeve and the second sleeve. With this structure, after the ratchet shaft is sleeved in the axial holes of the first sleeve and the second sleeve, the convex rib and the groove cooperate with each other to limit the ratchet shaft circumferentially relative to the flip plate, and only axial relative sliding occurs to each other. During the flipping process, since the fixed seat body is stationary, the axial compression drive of the ratchet shaft is more stable, which facilitates the circumferential rotation of the flip plate. After reaching the appropriate position, it can be firmly engaged with the second ratchet teeth to achieve hovering.

[0017] Furthermore, the ratchet suspension structure comprises a ratchet shaft, the ratchet shaft is provided with a first ratchet tooth, the fixed seat plate or the flip splint is provided with a second ratchet tooth, the first ratchet tooth is used to mesh with the second ratchet tooth; the ratchet shaft can slide axially relative to the fixed seat plate and / or the flip splint (the axial sliding distance satisfies the adaptation distance that the meshing ratchet teeth can be circumferentially rotated and misaligned with each other, and too large an axial distance will cause difficulty in re-engagement; the above-mentioned axial sliding of the ratchet shaft can be axial sliding relative to the fixed seat plate or the flip splint alone, or can be axial sliding relative to the fixed seat plate and the flip splint at the same time); With this structure, when the flipping splint is flipped relative to the fixed seat plate, the two meshing ratchet teeth rotate circumferentially relative to each other, and the two meshing ratchet teeth are misaligned and separated from each other under the guidance and compression of the tooth shape of the ratchet teeth, so as to ensure the smooth flipping of the flipping splint relative to the fixed seat plate. During this process, the ratchet shaft and the fixed seat plate or flipping splint meshed with it also slide axially; after flipping to the required angle, the two ratchet teeth can be manually brought axially closer to each other to mesh with each other again, thereby fixing the angle after flipping. During this process, the ratchet shaft and the fixed seat plate or flipping splint meshed with it also slide axially in the opposite direction of the flipping process.

[0018] The present application also provides a board clamp, which includes the hovering structure described above. The board clamp adopts this hovering structure. During the process of clamping documents, the hovering position, that is, the size of the opening, can be flexibly adjusted according to the thickness of the document before clamping. Moreover, during the process of the hovering structure flipping open to form an opening, and the process of releasing the hovering to achieve document clamping, the operation does not require the use of both hands at the same time, and can be performed with one hand.

[0019] The present application also provides a document booklet, which contains the hovering structure described above. When the document booklet adopts this hovering structure, the hovering position, that is, the size of the opening, can be flexibly adjusted according to the thickness of the document during the process of clamping the document, and then the document can be clamped; moreover, during the process of the hovering structure flipping open to form an opening, and the process of releasing the hovering to achieve document clamping, the operation does not require the use of both hands at the same time, and can be performed with one hand.

[0020] The present application also provides a document folder, which contains the hovering structure described above. When adopting this hovering structure, the document folder can flexibly adjust the hovering position, that is, the size of the opening, according to the thickness of the file during the process of clamping the file, and then clamp the file; moreover, during the process of the hovering structure flipping open to form an opening, and the process of releasing the hovering to achieve the holding of the file, the structure does not need to use both hands at the same time, and can be operated with one hand.

[0044] As attached Figure 1-19 The clamping plate suspension structure for clamping documents and the like provided in the present application comprises a fixed base plate 1 and a flip clamping plate 2 which can rotate in a relative circumferential direction, and a torsion spring 3 (torsion spring) is provided between the fixed base plate 1 and the flip clamping plate 2, and the torsion spring 3 is used to drive the flip clamping plate 2 and the fixed base plate 1 to clamp each other (specifically, the flip clamping plate 2 is flipped to a certain opening angle relative to the fixed base plate 1, and the force acting on the flip clamping plate 2 is released, at which time the restoring force of the torsion spring 3 can drive the flip clamping plate 2 to clamp the fixed base plate 1, and tighten the folder between the two). The fixed seat plate 1 and the flipping plate 2 are fixed); a ratchet suspension structure is also provided between the fixed seat plate 1 and the flipping plate 2, and the ratchet suspension structure can be used for flipping and hovering the flipping plate 2 relative to the fixed seat plate 1, that is, the ratchet suspension structure can make the flipping plate 2 flip circumferentially to a certain angle relative to the fixed seat plate 1 through the meshing action of the ratchet teeth, and then the flipped angle can be fixed (suspended), so as to realize the hovering of the flipping plate 2 relative to the fixed seat plate 1 and the fixing of the angle at the angle, so as to facilitate the placement of documents in the opening of the angle formed after the two are flipped relative to each other.

[0045] By adopting the above structure, the present application realizes the flipping and hovering of the flipping splint relative to the fixed seat plate through a ratchet hovering structure. The ratchet teeth are a kind of helical tooth structure, and the meshing angle of the two can be adjusted in a wide range. Therefore, the use of this ratchet hovering structure can realize the flipping and hovering of the flipping splint relative to the fixed seat plate at multiple angles. The hovering angle and position can be flexibly adjusted according to the thickness of the document to be clamped, and it has stronger adaptability.

[0046] As attached Figure 3-5 ,and Fig. 9 , Figure 13-14 , Figure 17-Figure 18As shown, the ratchet suspension structure described in the present application includes a ratchet shaft 4 and a compression spring 5, the ratchet shaft 4 is provided with a first ratchet tooth 401, the fixed seat plate 1 or the flip clamp 2 is provided with a second ratchet tooth 6, the first ratchet tooth 401 is used to mesh with the second ratchet tooth 6, the compression spring 5 abuts against one end of the ratchet shaft 4 and is used to drive the ratchet shaft 4 to axially elastically operate (the axial elastic operation here specifically refers to the mutual meshing ratchet teeth being squeezed and circumferentially displaced against each other during the flipping and hovering process, and under the action of the elastic deformation force of the compression spring 5, the first ratchet tooth 401 and the second ratchet tooth 6 on the ratchet shaft 4 will be driven to axially temporarily move away (the compression spring 5 is axially pushed and compressed by the ratchet shaft 4) or approach and mesh again (the compression spring 5 is axially stretched and reset, and the top Push the ratchet shaft 4 so that the first ratchet teeth 401 on it mesh with the second ratchet teeth again); specifically, the extension direction of the first ratchet teeth 401 and the second ratchet teeth 6 is along the axial direction of the ratchet shaft 4, extending relative to each other to achieve mutual meshing, and the first ratchet teeth 401 are evenly distributed along the circumference of the ratchet shaft 4 to form a ratchet disk, and the second ratchet teeth 6 are also adapted to be arranged to form a ratchet disk structure, and the two are meshed through the axial elastic pushing force of the compression spring 5 on the ratchet shaft 4; in the process of circumferential rotation of the flip splint 2 relative to the fixed seat plate 1, the meshing ratchet teeth interact with each other, and under the guiding action of the inclined surface of the ratchet teeth, the ratchet shaft 4 can axially push the compression spring 5, and the compression spring 5 is compressed, so that the circumferential misaligned rotation and re-engagement of the ratchet teeth are achieved, thereby achieving flipping and hovering at different positions.

[0047] By adopting the above structure, the present application provides a first ratchet tooth on the ratchet shaft, and a second ratchet tooth on the fixed seat plate or the flipping splint, and then the two ratchet teeth can mesh with each other; when the flipping splint rotates circumferentially relative to the fixed seat plate and flips, the ratchet shaft undergoes axial elastic operation due to the pushing action of the tooth meshing, and the pushing compression spring is compressed; when the flipping splint flips to a suitable position, the flipping stops, and at this time the compression spring resets and pushes the ratchet shaft to run in the opposite direction, and under the pushing force of the compression spring, the first ratchet tooth and the second ratchet tooth are firmly meshed with each other, so that the flipping angle of the flipping splint is fixed and hovering is achieved, and at this time, a document can be placed in the opening formed between the fixed seat plate and the flipping splint; then the end of the ratchet shaft is pressed so that the ratchet shaft Axial operation occurs again and the compression spring is pushed and compressed. In this process, the first ratchet tooth on the ratchet shaft is temporarily disengaged from the second ratchet tooth provided on the fixed seat plate or the flip clamp. At this time, the torsion spring drives the flip clamp to close toward the fixed seat plate under the action of its own restoring force, so as to clamp the placed document. The structure of the present application that relies on the engagement of ratchet teeth to achieve hovering can adjust different hovering positions as needed. The hovering position is not unique, so it can meet the clamping needs of documents of different thicknesses and flexibly adjust the opening size. Moreover, the hovering structure of the present application is simple to operate. You only need to flip the flip clamp with one hand. When clamping, you only need to press the end of the ratchet shaft with one hand, so that the engaged ratchet teeth are temporarily separated from each other and the torsion spring drives the flip clamp to reset.

[0048] Specifically, the suspension structure of the present application is further described in detail through the following two embodiments:

[0049] Example 1

[0050] As attached Figure 1-9 As shown, the hovering structure of this example, wherein the second ratchet teeth 6 are arranged on the flip splint 2, and the first ratchet teeth 401 of the ratchet shaft 4 are meshed with the second ratchet teeth 6 through the pushing action of the compression spring 5; specifically, in this example, the first ratchet teeth 401 on the ratchet shaft 4 and the second ratchet teeth 6 arranged on the flip splint 2 are axially meshed with each other through the pushing action of the compression spring 5, for details, refer to the attached Fig. 9As shown in the cross-sectional view; with this structure, when the flipping splint 2 is flipped relative to the fixed seat plate 1, the two ratchet teeth push each other, which will drive the ratchet shaft 4 to axially push the compression spring 5 to elastically compress. In this process, the first ratchet tooth 401 follows the ratchet shaft 4 to slide axially relative to the second ratchet tooth 6, and the positions of the meshing teeth on the two ratchet teeth are misaligned, so that the flipping splint 2 can be smoothly flipped circumferentially relative to the fixed seat plate 1, and when it is flipped to the appropriate position, it stops flipping; at this time, the compression spring 5 resets in the reverse direction, axially pushes the first ratchet tooth 401 and the flipping splint 2 The second ratchet teeth 6 are firmly engaged with each other to achieve a suspended fixation in the flipping position. At this time, the torsion spring 3 is torsionally deformed under the action of the ratchet teeth meshing force; at this time, the document can be placed within the flipping angle formed between the fixed base plate 1 and the flipping clamping plate 2, and then one axial end of the ratchet shaft 4 is pressed so that it pushes the compression spring 5 again to be compressed. At this time, the two meshing ratchet teeth are temporarily disengaged. At this time, the torsion spring 3 has no binding force of the ratchet teeth meshing, and can automatically restore to drive the flip clamping plate 2 and the fixed base plate to clamp each other, thereby tightening the document placed between the two.

[0051] As attached Figure 2-6 , Fig. 9 As shown, the fixed seat plate 1 described in the present application is provided with a stepped shaft 101 on one side along the length direction, the torsion spring 3 is sleeved on the stepped shaft 101, and the compression spring 5 is located in the axial hole of the stepped shaft 101 (one end abuts on the inner end wall of the axial hole, and the other end abuts on the axial end of the ratchet shaft 4), and one end of the ratchet shaft 4 is sleeved in the stepped shaft 101 and abuts against the compression spring 5; a sleeve sleeve 201 is provided at each end of the flip splint 2 along the length direction, and the pressing end 403 of the ratchet shaft 4 (that is, when the document needs to be clamped, the first ratchet tooth 401 is temporarily separated from the second ratchet tooth 6, and the torsion spring 3 is not bound and can drive the flip splint 2 and the fixed seat plate 1 to clamp the document to each other) and one end of the stepped shaft 101 are respectively sleeved in the corresponding sleeve sleeves 201 at both ends (refer to the attached drawing for details). Figure 2 As shown in the figure, the pressing end 403 of the ratchet shaft 4 and the end of the step shaft 101 and the fitting sleeve 201 are arranged opposite to each other; with this structure, the torsion spring 3 can be limited between the step shaft 101 and the ratchet shaft 4 to prevent it from escaping; and through the fitting of the fitting sleeve 201 with the pressing end 403 of the ratchet shaft 4 and one end of the step shaft 101, the circumferential relative rotation of the flip splint 2 and the fixed seat plate 1 is achieved.

[0052] As attached Figure 2-6 , Figure 8-9As shown, the second ratchet teeth 6 described in the present application are located on the shaft wall of the fitting sleeve 201 described at one end, and the second ratchet teeth 6 extend along the axial direction, and the corresponding first ratchet teeth 401 extend axially relative to the second ratchet teeth 6 and engage with each other; that is, the two ratchet teeth are axially opposite to each other, and under the pushing action of the compression spring 5, they are axially engaged with each other, and during the flipping process, the ratchet shaft 4 is pushed to slide axially, thereby realizing the smooth circumferential rotation and repeated suspension of the flipping splint 2; and, through the engagement of the axial ratchet teeth, the axial drive of the ratchet shaft 4 is realized during the flipping process, thereby simplifying the structure and saving space.

[0053] As attached Figure 3-5 , Figure 7-9 As shown, the ratchet shaft 4 described in the present application is axially provided with a convex rib 402 (that is, the convex rib 402 extends along the axial length direction of the shaft, and multiple ribs can be provided), and the corresponding shaft hole of the step shaft 101 is provided with a groove 102 that slidably cooperates with the convex rib 402 (multiple grooves can also be provided, corresponding to the multiple convex ribs 402); with this structure, when the ratchet shaft 4 is fitted into the shaft hole of the step shaft 101, the convex rib 402 and the groove 102 slide with each other, so that the ratchet shaft 4 is circumferentially limited relative to the fixed seat body 1, and only axial relative sliding occurs to each other; this method can make the ratchet shaft 4 rotate without following the circumferential rotation of the flip splint 2, so that it is more labor-saving during the flipping process of the flip splint 2, and when it is flipped to a suitable position, it can be firmly engaged with the ratchet shaft 4 to achieve hovering.

[0054] As attached Figure 4 As shown, the force-applying portion of the flip splint 2 described in the present application is provided with anti-slip ribs 202, and a plurality of ribs may be provided. With this structure, when force is applied to this portion, the flip splint is not prone to slipping during the circumferential flipping process relative to the fixed seat body.

[0055] The specific working principle and process of the suspension structure corresponding to this example are as follows: first, the compression spring is pushed into the shaft hole along the axial direction of the step shaft, and then the torsion spring is sleeved on the outer peripheral wall of the step shaft, and one end can abut against the step surface; then the ratchet shaft is inserted into the shaft hole of the step shaft and abuts against the compression spring, and the convex rib on the ratchet shaft and the groove on the wall of the step shaft hole slide and cooperate with each other to circumferentially limit the ratchet shaft and the fixed seat body; then the pressing end of the ratchet shaft is pressed to shorten its length and put it between the fitting sleeves set at both ends of the length of the flip splint, and the pressing end and the fitting end of the step shaft are respectively sleeved into the corresponding fitting sleeves, and the compression spring pushes the fixed seat body and the ratchet shaft, so that the assembly formed by the two is sleeved on the two fitting sleeves to form a complete suspension structure; the fixed seat body can be provided with a mounting hole to fix the suspension structure on the plate body 7 for holding documents or the document book body or the document folder body 8 (refer to the attached Figure 19-20), when it is necessary to place a document, one hand holds the hovering structure up and down to apply force, and the specific force-applying part is located at the rear end of the flip splint, that is, Figure 4 The position of the middle anti-slip rib, during this process the flipping splint flips circumferentially relative to the fixed seat plate, during the flipping process, due to the circumferential limitation of the fixed seat plate and the ratchet shaft to each other, during the circumferential sliding process of the first ratchet teeth and the second ratchet teeth, the ratchet shaft is squeezed to slide axially relative to the fixed seat plate and the flipping splint, and the compression spring is pushed inward to be axially compressed until it is flipped to a suitable position, and the flipping stops; at this time, under the action of the reverse pushing force of the compression spring, the first ratchet teeth and the second ratchet teeth are firmly meshed with each other, achieving suspension at this position, at this time the flipping splint and the fixed seat The bodies form a certain opening angle with each other, so that documents can be placed. At this time, the torsion spring is in a torsion deformation state; after the documents are placed, the pressing end of the ratchet shaft is pressed, and the compression spring is pushed inward and compressed, and the first ratchet tooth axially follows and slides inward and is temporarily separated from the second ratchet tooth. At this time, the torsion spring has no binding force and can be restored to drive the flip clamp and the fixed seat plate to clamp the documents between the two; after clamping, under the pushing action of the extension reset force of the compression spring, the two ratchet teeth mesh with each other again, waiting for the next flipping operation.

[0056] Example 2

[0057] As attached Figure 11-14 , Figure 17-18 As shown, in the suspension structure of this example, a second ratchet tooth 6 is provided on the fixed seat body 1, the ratchet shaft 4 is sleeved on the flip splint 2 and is circumferentially limited with the flip splint 2, and the first ratchet tooth 401 is pushed by the compression spring 5 and meshed with the second ratchet tooth 6; specifically, the first ratchet tooth 401 and the second ratchet tooth 6 extend axially relative to each other and mesh with each other; with this structure, when the flip splint 2 rotates and flips circumferentially relative to the fixed seat plate 1, since the ratchet shaft 4 and the flip splint 2 are circumferentially limited to each other, the two will synchronously flip circumferentially relative to the fixed seat plate 1, and in this process, the two ratchet teeth will push each other, which will drive the ratchet shaft 4 axially The pushing compression spring 5 is compressed inward, so that the flip clamp 2 can flip around smoothly. After flipping to the appropriate position, the flipping stops. At this time, the compression spring 5 resets in the opposite direction to push the first ratchet tooth 401 and the second ratchet tooth 6 on the fixed seat plate 1 to engage firmly and achieve suspension. At this time, the torsion spring 3 undergoes torsion deformation under the action of the ratchet tooth meshing force. At this time, the file can be placed within the flipping angle formed between the fixed seat plate 1 and the flip clamp 2, and then one end of the ratchet shaft 4 is pressed to push the compression spring 5 again to compress. At this time, the two meshing ratchet teeth are temporarily disengaged. At this time, the torsion spring 3 has no binding force of the ratchet teeth meshing, and can automatically return to drive the flip clamp 2 and the fixed seat plate to clamp the file tightly.

[0058] As attached Figure 2-18As shown, the flip splint 2 described in the present application is provided with a first shaft sleeve 203 and a second shaft sleeve 204 on one side along its length direction, and the torsion spring 3 is located between the first shaft sleeve 203 and the second shaft sleeve 204; the compression spring 5 is located in the axial hole of the second shaft sleeve 204 (one end of the compression spring 5 abuts against the inner end wall of the axial hole of the second shaft sleeve 204, and the other end abuts against one end of the ratchet shaft 4); the ratchet shaft 4 is sleeved in the axial holes of the first shaft sleeve 203 and the second shaft sleeve 204 (at this time, the torsion spring 3 is sleeved on the ratchet shaft 4), and one end thereof abuts against the compression spring 5; a third shaft sleeve 103 is provided at each end of the fixed seat body 1 along the length direction, and the pressing end 403 of the ratchet shaft 4 (that is, the pressing end 403 of the ratchet shaft 4) is required. When it is necessary to clamp a document, the first ratchet tooth 401 is temporarily separated from the second ratchet tooth 6, and the torsion spring 3 is not bound and can drive the flip clamp 2 and the fixed seat plate 1 to clamp the pressed end of the document to each other) and one end of the second shaft sleeve 204 are respectively sleeved in the axial holes of the two third shaft sleeves 103; with this structure, the torsion spring 3 can be limited between the first shaft sleeve 203 and the second shaft sleeve 204, that is, the inner diameter of the torsion spring 3 is not larger than the inner diameter of the first shaft sleeve 203 and the second shaft sleeve 204 to prevent it from detaching; and through the fitting of the third shaft sleeve 103 with the pressing end 403 of the ratchet shaft 4 and one end of the second shaft sleeve 204, the circumferential relative rotation and flipping of the flip clamp 2 and the fixed seat plate 1 are realized to form an angle for placing the document.

[0059] As attached Fig.11 , Fig.14 , Figure 16-18 As shown, the second ratchet teeth 6 described in the present application are located on the end wall of the third shaft sleeve 103 at one end, and the second ratchet teeth 6 extend along the axial direction, and the corresponding first ratchet teeth 401 extend and mesh with the second ratchet teeth 6 relatively along the axial direction; with this structure, the ratchet teeth extending in the axial direction can drive the axial sliding of the ratchet shaft 4 and the compression of the compression spring 5 during the relative rotation process, thereby realizing the effective circumferential rotation of the flip splint 2, forming different hovering angles, and realizing the axial drive of the ratchet shaft 4 during the flipping process, simplifying the structure and saving space.

[0060] As attached Figure 13-15 and Fig.17As shown, a convex rib 402 is axially arranged on the shaft body of the ratchet shaft 4 described in the present application, and a sliding groove 205 that slidably cooperates with the convex rib 402 is correspondingly arranged in the shaft hole of the first shaft sleeve 203 and the second shaft sleeve 204; with this structure, after the ratchet shaft 4 is sleeved in the shaft hole of the first shaft sleeve 203 and the second shaft sleeve 204, the convex rib 402 cooperates with the sliding groove 205, so that the ratchet shaft 4 is circumferentially limited relative to the flip splint 2, and only axial relative sliding occurs to each other; during the flipping process, since the fixed seat body 1 is stationary, the axial compression drive of the ratchet shaft 4 is more stable, which facilitates the circumferential rotation of the flip splint 2. After flipping to the appropriate position, under the action of the top thrust of the compression spring 5, the first ratchet teeth 401 can be firmly meshed with the second ratchet teeth 6 to achieve hovering.

[0061] The specific working principle and process of the suspension structure corresponding to the above example of the present application are as follows: first, the compression spring is pushed into the axial hole of the second sleeve along the axial direction of the second sleeve, and then the torsion spring is placed between the first sleeve and the second sleeve, and the ratchet shaft is inserted into the first sleeve and the second sleeve. The convex ribs on the ratchet shaft and the sliding grooves on the hole walls of the first sleeve and the second sleeve slide with each other to circumferentially limit the ratchet shaft and the flip clamp. At this time, one end of the ratchet shaft abuts against the compression spring; then the pressing end of the ratchet shaft is pressed to shorten its length and put it between the third sleeves at both ends of the fixed seat plate in the length direction, and the pressing end of the ratchet shaft and the sleeve end of the second sleeve are respectively inserted into the third sleeves at the corresponding ends, thereby realizing the assembly of the suspension structure of this example; the fixed seat body can be provided with a mounting hole to fix the suspension structure on the plate body 7 for holding documents (as shown in the attached figure). Fig.19As shown in the figure, when it is necessary to place a document, the hovering structure is gripped up and down with one hand to apply force, and specifically the force-applying part is located at the front end of the flipping splint, i.e., the position of the opening end for placing the document, and specifically the front end of the flipping splint is bent upward relative to the fixed seat plate, and in this process the flipping splint is flipped circumferentially relative to the fixed seat plate, and in the flipping process, since the flipping splint and the ratchet shaft are circumferentially limited to each other, during the circumferential sliding process of the first ratchet teeth and the second ratchet teeth, the ratchet shaft is squeezed to slide axially inwardly to push the compression spring until it is flipped to a suitable position, and the flipping stops; at this time, under the reverse pushing force of the compression spring, the first ratchet teeth and the second ratchet teeth are pressed against each other. The ratchet teeth are firmly engaged with each other to achieve hovering in this position, at which time a certain opening angle is formed between the flipping splint and the fixed seat body, so that documents can be placed, and the torsion spring is in a torsional deformation state at this time; after the documents are placed, the pressing end of the ratchet shaft is pressed, and the compression spring is pushed inward and compressed, and the first ratchet tooth axially follows and slides inward and is temporarily separated from the second ratchet tooth, at which time the torsion spring has no binding force and can be restored to drive the flipping splint and the fixed seat plate to clamp the documents between the two; after clamping, under the pushing action of the extension reset force of the compression spring, the two ratchet teeth are engaged with each other again, waiting for the next flipping operation.

[0062] Example 3

[0063] The suspension structure of Example 3 is different from that of Examples 1 and 2 mainly in that the compression spring 5 is omitted in the ratchet suspension structure adopted therein; specifically, the ratchet suspension structure of this example includes a ratchet shaft 4, on which a first ratchet tooth 401 is provided, and on which a second ratchet tooth 6 is provided on the fixed seat plate 1 or the flip splint 2, and the first ratchet tooth 401 is used to engage with the second ratchet tooth 6; the ratchet shaft 4 can slide axially relative to the fixed seat plate 1 and / or the flip splint 2 (the axial sliding of the ratchet shaft 4 mentioned above can be an axial sliding relative to the fixed seat plate or the flip splint alone, or can be an axial sliding relative to the fixed seat plate and the flip splint at the same time); the specific positional relationship and connection relationship of the above-mentioned components can be referred to in the attached Figure 1-9 , omitting the attachment Figure 1-9 The compression spring 5 in.

[0064] Specifically, in one specific implementation of Example 3, the attached Figure 1-9The compression spring 5 is omitted, and the other structures remain basically unchanged; at this time, the ratchet shaft 4 is provided with a first ratchet tooth 401, and the corresponding second ratchet tooth 6 is provided on the flip splint 2; there is a certain gap between the other end of the ratchet shaft 4 without the first ratchet tooth 401 and the inner end wall of the stepped shaft 101 provided on the fixed seat plate 1, and the gap is provided to adapt to the process when the flip splint 2 is flipped relative to the fixed seat plate 1, and the mutually meshing ratchet teeth are in the process of relative circumferential operation, the ratchet teeth are circumferentially displaced and squeezed with each other, so that the ratchet teeth can be turned relative to each other. The wheel shaft 4 runs axially inwardly for a certain distance relative to the flip clamp 2 to ensure smooth flipping; after flipping to a suitable angle, the ratchet shaft 4 can be manually pushed axially in the reverse direction so that the first ratchet teeth 401 thereon and the second ratchet teeth 6 provided on the flip clamp 2 can be firmly engaged again to achieve hovering; after placing the document, the ratchet shaft 4 is pushed inward again so that the two engaged ratchet teeth are temporarily separated, and the torsion spring is reset to tighten the document; after clamping, the ratchet shaft 4 can be pushed in the reverse direction so that the two ratchet teeth can be engaged with each other again, waiting for the next flipping operation.

[0065] Specifically, another specific implementation in Example 3 is to attach Figure 10-18 The compression spring 5 is omitted, and other structures remain basically unchanged; at this time, the ratchet shaft 4 is provided with a first ratchet tooth 401, and the corresponding second ratchet tooth 6 is provided on the fixed seat plate 1; there is a certain gap between the other end of the ratchet shaft 4 without the first ratchet tooth 401 and the inner end wall of the shaft hole of the second shaft sleeve 204 provided on the flip clamp 2, and the setting of the gap is to adapt to the process when the flip clamp 2 is flipped relative to the fixed seat plate 1, and the mutually meshing ratchet teeth are in the process of relative circumferential operation, the ratchet teeth are circumferentially displaced and squeezed with each other, so that The ratchet shaft 4 runs axially inwardly for a certain distance relative to the fixed base plate 1 to ensure smooth flipping; after flipping to a suitable angle, the ratchet shaft 4 can be manually pushed axially in the reverse direction so that the first ratchet teeth 401 thereon and the second ratchet teeth 6 provided on the fixed base plate 1 are firmly engaged again to achieve hovering; after placing the file, the ratchet shaft 4 is pushed inward again so that the two engaged ratchet teeth are temporarily separated, and at this time the torsion spring is reset to tighten the file; after clamping, the ratchet shaft 4 can be pushed in the reverse direction so that the two ratchet teeth are engaged with each other again, waiting for the next flipping operation.

[0066] As attached Fig.19As shown, the present application also provides a plate clamp, which includes the above-mentioned hovering structure (including but not limited to the hovering structure described in Example 1 or Example 2 or Example 3), that is, the hovering structure of the present application is fixed on the plate body 7 through the fixed seat plate 1 therein to achieve the clamping effect on the file. Specifically, a connecting hole can be set on the fixed seat plate 1, and the fixed connection between the hovering structure and the plate body can be achieved by rivets or screws; the plate clamp using this hovering structure can flexibly adjust the hovering position, that is, the size of the opening according to the thickness of the file during the clamping process, and then clamp it; moreover, the structure does not require both hands at the same time in the process of opening the hovering structure to form an opening, and in the process of releasing the hovering to achieve the clamping of the file, and can be operated with one hand; in addition, since the hovering position of the structure can be adaptively changed according to the thickness of the clamped file, compared with the existing hovering structure with a single hovering position and mainly realizing the positioning of the same position by snapping (the snapping at the same position is easy to wear and fail), the ratchet engagement hovering structure of the present application is not easy to cause the paper clamping part of the clamp to fall off, so it will not cause failure damage.

[0067] As attached Fig. 20 As shown, the present application further provides a file book or file folder structure, which contains the above-mentioned hovering structure (including but not limited to the hovering structure described in Example 1 or Example 2 or Example 3). When the file book or file folder adopts this hovering structure, the hovering position, that is, the size of the opening, can be flexibly adjusted according to the thickness of the file during the process of clamping the file, and then the file can be clamped; moreover, when the hovering structure is flipped open to form an opening, and when the hovering is released to achieve the file clamping, the structure does not need to use both hands at the same time, and the operation can be achieved with one hand; specifically, the present application Please fix the above-mentioned suspension structure to one end of the document book body or the document folder body 8, and place the document to be clamped in the document book body or the document folder body 8 (the body here forms a cover on the upper and lower sides of the document), and the position where the suspension structure is set has a hollow position to facilitate the flipping and hovering operations of the flipping plate and the fixed seat plate of the suspension structure, and then clamp the document; the suspension structure of the present application has a wide range of applications, and can be used in board folders, document books or document folders, etc., as well as other structures that need to be clamped, and the suspension angle can be adjusted according to the thickness of the documents clamped by these structures, which is easy to operate.
