Description

Technical Field

[0001] The present invention relates to the field of fasteners, and more particularly to a toothed tiger clip and its production process. Background Art

[0002] A tiger clip is a common fastening and connecting member, mainly used for the hoisting and connection of steel structures. Due to its simple installation, no need for drilling or welding, strong load-bearing capacity, flexible use and other characteristics, it is widely used in construction projects, pipeline construction and even underground operations.

[0003] The related technology can refer to the Chinese patent with the publication number CN209007388U, which discloses a tiger clip, including a tiger mouth plate, an upper connecting plate and a lower connecting plate. There are two tiger mouth plates. The upper ends of the two tiger mouth plates are connected by the upper connecting plate, and the lower ends of the tiger mouth plates are connected by the lower connecting plate. The tiger mouth plate is provided with a tiger mouth-shaped opening, and a wave tooth is provided below the opening. The tiger mouth plate is provided with an L-shaped reinforcing rib, and the reinforcing rib is an inward groove. The tiger mouth plate is also provided with bolt holes, the upper connecting plate is also provided with bolt holes, the lower connecting plate is provided with mounting holes, and the upper connecting plate is also provided with an opening, and two downward flanges are provided at the opening.

[0004] In view of the above related technology, the thread fit between the bolt hole and the bolt is mainly realized by the internal thread provided on the inner wall of the bolt hole. Usually, one type of internal thread only corresponds to one type of bolt. Since different types of bolts have different pitches, when the original bolt is lost or damaged, it is necessary to select a bolt with the same model as the original bolt to fit with the threaded hole. Therefore, it is inconvenient to use. Summary of the Invention

[0005] In order to improve the convenience of using the tiger clip, the present application provides a toothed tiger clip and its production process.

[0006] The present application provides a toothed tiger clip, adopting the following technical solutions:

[0007] A toothed tiger clamp, comprising two parallel locking plates, a first connecting plate perpendicularly fixed between the two locking plates. Through holes coaxial with each other are provided on both locking plates. The first connecting plate is located on one side of the locking plates along the width direction, and an avoidance opening is provided on the side of the first connecting plate away from the through holes. A number of tooth blocks are arranged in the avoidance opening. The tooth blocks are arranged along the length direction of the locking plates and are all fixedly connected to the first connecting plate. Connecting holes for bolts to pass through are opened at one ends of both locking plates away from the through holes. An arc-shaped plate is provided on the side of the locking plate close to the first connecting plate. The arc-shaped plate is arranged circumferentially along the inner wall of the connecting hole. An opening communicating with the connecting hole is also provided on the locking plate. One side edge of the opening is set as a screwing-in edge. The screwing-in edge intersects with the inner wall of the connecting hole, and the direction from the arc-shaped plate away from the screwing-in edge is the same as the screwing-in direction of the bolt during installation. The arc-shaped plate gradually extends away from the locking plate along the direction away from the screwing-in edge. When the bolt is located in the connecting hole, the arc-shaped plate cooperates with the external thread of the bolt.

[0008] By adopting the above technical solution, the two locking plates are connected by the first connecting plate. The through holes are used for an external connecting mechanism to pass through. During use, an external fixing point is placed in the avoidance opening, and a bolt passes through any connecting hole, and the first end of the external thread on the bolt is screwed into the connecting hole from the opening. At this time, the bolt rotates along the direction from the screwing-in edge towards the arc-shaped plate. When the thread of the bolt contacts the end face of the arc-shaped plate away from the locking plate, continue to rotate the bolt. At this time, under the limiting action of the arc-shaped plate on the thread of the bolt, the bolt moves along its own axis direction to complete the thread fit between the arc-shaped plate and the bolt, thereby facilitating the clamping and fixing of the external fixing point in the avoidance opening by the bolt. During this process, the tooth blocks are beneficial to improving the clamping stability of the external fixing point. The thickness of the arc-shaped plate gradually increases along the extending direction of the arc-shaped plate away from the screwing-in edge, thereby being applicable to bolts with different pitches and being beneficial to improving the use convenience of the tiger clamp.

[0009] Optionally, a top plate is fixedly connected to the side of the first connecting plate close to the locking plate. The top plate is located between the two locking plates, and both locking plates are in contact with the top plate. The top plate is provided with connecting holes, an arc-shaped plate, and an opening the same as those on the locking plates, and the axis of the connecting hole on the top plate is perpendicular to the axis of the through hole.

[0010] By adopting the above technical solution, after an external connecting rod passes through the through hole, another set of bolts can be installed at the connecting holes of the top plate, and thread fit is carried out with the corresponding arc-shaped plate and opening and the bolts. When the bolts on the top plate are rotated, the bolts approach the external connecting rod in the through hole and clamp and fix it, further improving the connection stability of the tiger clamp.

[0011] Optionally, the two locking plates are respectively set as the first fastening plate and the second fastening plate. On the side of the second fastening plate facing away from the first connecting plate, a second connecting plate is fixedly connected. The second connecting plate is arranged parallel to the first connecting plate, and the second connecting plate is provided with the same avoidance opening and tooth block as the first connecting plate. On the side of the second connecting plate away from the second fastening plate, a card slot is opened. On the side of the first fastening plate away from the first connecting plate, a clamping plate is fixedly connected. The clamping plate passes through the card slot and is clamped with the second connecting plate.

[0012] By adopting the above technical solution, the first connecting plate is connected to the first fastening plate through the cooperation of the clamping plate and the card slot, so that the second connecting plate and the first connecting plate cooperate to support and fix the first fastening plate and the second fastening plate, further improving the structural strength between the first fastening plate and the second fastening plate and enhancing the locking stability of the tiger clamp.

[0013] Optionally, a sleeve plate is provided on the side of the second fastening plate facing away from the first fastening plate. The sleeve plate is clamped outside the second fastening plate and connected to the second fastening plate. The sleeve plate is provided with a round hole coaxial with the connection hole on the second fastening plate. And on the side of the sleeve plate facing away from the second fastening plate, a moving ring is rotatably connected around the axis of the round hole. The moving ring is provided with an abutting rod. The abutting rod is arranged along the diameter direction of the moving ring, and the abutting rod passes through the moving ring and is threadedly connected with the moving ring.

[0014] By adopting the above technical solution, the sleeve plate is connected to the second fastening plate. When installing the bolt, the bolt is sequentially passed through the round hole and the connection hole. When the diameter of the bolt is smaller than the diameter of the connection hole, the bolt is likely to shake in the connection hole. At this time, the moving ring is rotated to make the abutting rod at the maximum gap between the bolt and the inner wall of the connection hole. The abutting rod is rotated to make the abutting rod contact the outer circle of the bolt and clamp and fix the bolt radially, thereby being applicable to bolts of different diameters and further improving the use convenience of the tiger clamp.

[0015] Optionally, the sleeve plate includes a supporting part and two side plates. The supporting part is attached to the surface of the second fastening plate facing away from the first fastening plate. The moving ring is located on the side of the supporting part facing away from the second fastening plate. The two side plates are respectively located on both sides of the second fastening plate along the width direction and are both fixedly connected to the supporting part. On the sides of the first connecting plate and the second connecting plate close to the supporting part, positioning blocks are fixedly provided. The two positioning blocks gradually move away from each other along the direction from the second fastening plate to the first fastening plate. The side plates are provided with positioning grooves adapted to the positioning blocks. When the positioning blocks are located in the positioning grooves, they contact the inner walls of the positioning grooves.

[0016] By adopting the above technical solution, the first connecting plate and the second connecting plate limit the two side plates through the cooperation of the positioning blocks and the positioning grooves, so that the supporting part is attached to the corresponding second fastening plate. At the same time, the sleeve plate is separately arranged from the tiger clamp and is supported by a post-assembly method. When the diameter of the bolt is adapted to the diameter of the connection hole, there is no need to assemble the sleeve plate, further improving the use convenience.

[0017] Optionally, the arc-shaped plate is integrally formed with the corresponding locking plate, and is formed by bending the side edges of the connecting holes on the corresponding locking plate.

[0018] The adoption of the above technical solution is beneficial to improving the processing convenience and structural strength of the curved plate.

[0019] Optionally, an abutment plate is provided on one side of the locking plate close to the connecting plate, the abutment plate is in contact with the locking plate, and a mounting hole is opened in the abutment plate along the transverse direction, the mounting hole is connected with the connecting hole, and the diameter of the mounting hole is no larger than the diameter of the connecting hole, and the arc plate is located on the side of the abutment plate away from the corresponding locking plate, and the abutment plate is also provided with a screw-in opening that is opposite to the opening, and the screw-in opening is located at one end of the arc plate along the length direction and is connected to the mounting hole.

[0020] By adopting the above technical solution, the arc plate is arranged on the abutment plate and is designed separately from the locking plate. When installing the bolt, the bolt is spirally matched with the abutment plate through the mounting hole and the screw-in opening on the abutment plate. After the abutment plate is limited, when the bolt is rotated, the bolt moves along the axial direction of the mounting hole, thereby facilitating the clamping of the external fixed point in the avoidance opening. At the same time, the abutment plate can be replaced, which is further suitable for bolts of different diameters, thereby improving the convenience of using the tiger clamp.

[0021] In a second aspect, the present application provides a production process for a toothed tiger card, which adopts the following technical solution:

[0022] Material preparation: Use metal sheets to make tiger card sheet raw materials by stamping or cutting;

[0023] Edge cutting: Cut the side of the raw material of the tiger card sheet to form a tooth block on the corresponding side of the raw material;

[0024] Punching 1: Punching the raw material of the tiger card sheet to form a through hole;

[0025] Punching 2: Use another set of punching tools to perform secondary punching to form connecting holes and openings;

[0026] Flanging: The raw material of the tiger card sheet is squeezed by stamping to form a curved plate;

[0027] Bending: Use a bending machine to bend the raw material of the tiger card sheet to form the tiger card;

[0028] Post-processing: Check the bent slot card to remove burrs and flash.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] The two locking plates are connected by the first connecting plate. The through hole is used for an external connecting mechanism to pass through. During use, an external fixing point is placed into the avoidance opening, and a bolt passes through any connecting hole, and the leading end of the external thread on the bolt is screwed into the connecting hole from the opening. At this time, the bolt rotates in the direction pointing from the screwing edge to the arc-shaped plate. When the thread of the bolt contacts the end face of the arc-shaped plate facing away from the locking plate, the bolt continues to rotate. At this time, under the limiting action of the arc-shaped plate on the thread of the bolt, the bolt moves along its own axis to complete the thread fit between the arc-shaped plate and the bolt, thereby facilitating clamping and fixing of the external fixing point in the avoidance opening by the bolt. During this process, the tooth block is beneficial to improving the clamping stability of the external fixing point. The thickness of the arc-shaped plate gradually increases along the extending direction of the arc-shaped plate away from the screwing edge, thereby being applicable to bolts with different pitches and being beneficial to improving the usability of the tiger clamp;

[0031] The sleeve plate is connected to the second fastening plate. When installing the bolt, the bolt passes through the round hole and the connecting hole in sequence. When the diameter of the bolt is smaller than the diameter of the connecting hole, the bolt is likely to shake in the connecting hole. At this time, the moving ring is rotated to make the abutting rod located at the maximum gap between the bolt and the inner wall of the connecting hole, and the abutting rod is rotated to make the abutting rod contact the outer circle of the bolt and clamp and fix the bolt radially, thereby being applicable to bolts with different diameters and further improving the usability of the tiger clamp;

[0032] The arc-shaped plate is arranged on the abutting plate and is separately designed from the locking plate. When installing the bolt, the bolt is in screw fit with the abutting plate through the installation hole and the screwing-in port on the abutting plate. After the abutting plate is limited, when the bolt is rotated, the bolt moves along the axis of the installation hole, thereby facilitating clamping of the external fixing point in the avoidance opening. At the same time, the abutting plate can be replaceably arranged, further being applicable to bolts with different diameters and improving the usability of the tiger clamp.

Detailed implementation manners

[0038] The following further describes the present application in detail with reference to all the drawings.

[0039] The embodiment of the present application discloses a toothed tiger clamp and its production process. Embodiment

[0040] Referring to Figure 1 and Figure 2 A toothed tiger clamp includes two parallel locking plates 1. The two locking plates 1 are respectively set as the first fastening plate 11 and the second fastening plate 12. A first connecting plate 21 is fixedly connected between the first fastening plate 11 and the second fastening plate 12. The first connecting plate 21 is located on the same side of the first fastening plate 11 and the second fastening plate 12 in the width direction, and the first connecting plate 21, the first fastening plate 11 and the second fastening plate 12 are integrally formed. A second connecting plate 22 is fixedly connected to the side of the second fastening plate 12 away from the first connecting plate 21. The second connecting plate 22 is parallel to the first connecting plate 21, and a plurality of card slots 221 are opened on the side of the second connecting plate 22 away from the second fastening plate 12. A clamping plate 111 corresponding to the card slots 221 one by one is fixedly connected to the side of the first fastening plate 11 away from the first connecting plate 21. The clamping plate 111 passes through the card slots 221 and is clamped with the second connecting plate 22.

[0041] Referring to Figure 1 and Figure 2 One side of the first connecting plate 21 in the width direction is fixedly connected with a top plate 25. The top plate 25 bends towards the direction close to the first connecting plate 21, and the side of the top plate 25 close to the first connecting plate 21 is located between the first fastening plate 11 and the second fastening plate 12. Both the first fastening plate 11 and the second fastening plate 12 are in contact with the top plate 25. The top plate 25 supports and positions the first fastening plate 11 and the second fastening plate 12, which is beneficial to improving the connection strength between the first fastening plate 11 and the second fastening plate 12.

[0042] Referring to Figure 1 and Figure 2, the first connecting plate 21, the top plate 25, the second connecting plate 22, the first fastening plate 11 and the second fastening plate 12 are integrally formed from the same metal thin plate and processed by bending. Through holes 13 are opened on one side of the first fastening plate 11 and the second fastening plate 12 close to the top plate 25, and the two through holes 13 are coaxial with each other. Connecting holes 14 are opened at one end of the first fastening plate 11 and the second fastening plate 12 away from the through holes 13, and openings communicating with the connecting holes 14 are provided on both the first fastening plate 11 and the second fastening plate 12. One side edge of the opening is arranged along the diameter direction of the connecting hole 14, and this side edge is set as the screwing-in edge 15. The outer circle of the connecting hole 14 is arranged in an involute shape from the center of the circle, and an arc-shaped plate 3 is provided along the circumferential direction of the connecting hole 14. In this embodiment, the arc-shaped plate 3 is formed by bending from the side edge of the inner wall of the connecting hole 14 towards the direction close to the first connecting plate 21, and one end of the arc-shaped plate 3 close to the center of the connecting hole 14 is close to one end of the screwing-in edge 15 close to the connecting hole 14.

[0043] Referring to Figure 1 and Figure 2 , when it is necessary to fix the tiger card, align the avoidance opening 23 with the external fixing point, so that the external fixing point enters the avoidance opening 23, and make the external fixing point face the connecting hole 14. The connecting hole 14 is used for installing a bolt. It should be noted that the external thread on the bolt is formed by helically arranged threads, and the distance between adjacent threads is the pitch. When installing the bolt, align the bolt with the connecting hole 14, and make the head end of the thread pass through the connecting hole 14 from the opening. It should be noted that the width of the screwing-in edge 15 is smaller than the pitch of the bolt, so that the fallen leaves do not interfere with the screwing-in edge 15 when passing through the opening.

[0044] Referring to Figure 1 and Figure 2 , since the side of the connecting hole 14 is arranged in an involute shape, the thickness of the arc-shaped plate 3 gradually increases along the direction away from the screwing-in edge 15, and the direction of the arc-shaped plate 3 away from the screwing-in edge 15 is the same as the rotation direction when the bolt is screwed in. When turning the bolt, the thread extends along the length direction of the arc-shaped plate 3. For the entire arc-shaped plate 3, there is a region where the thickness is adapted to the pitch of the bolt, and the thread contacts the arc-shaped plate 3 at this place. At this time, the arc-shaped plate 3 is located between two threads, so that the arc-shaped plate 3 is in threaded fit with some threads of the bolt. The thickness of the arc-shaped plate 3 is set to change gradually, which is convenient for matching with bolts of different pitches and improves the use convenience.

[0045] Referring to Figure 1 and Figure 2, under the action of the arc-shaped plate 3, when the bolt continues to rotate, the bolt approaches the external fixed point in the avoidance opening 23 along its own axis direction. When the bolt contacts the external fixed point, it clamps and positions the external fixed point. Further, a plurality of tooth blocks 24 are arranged in the avoidance opening 23. The tooth blocks 24 are arranged along the length direction of the first fastening plate 11, and the tooth blocks 24 are fixedly connected to the corresponding first connecting plate 21 or the second connecting plate 22. When the bolt abuts against the external fixed point, the tooth blocks 24 are located on the side of the external fixed point away from the bolt, which is conducive to improving the connection stability between the tiger card and the external fixed point.

[0046] Referring to Figure 1 and Figure 2 , when using the tiger card, connect another external connecting piece through the round hole. Taking the connecting rod as an example, the connecting rod is sequentially passed through the two through holes 13. The first fastening plate 11 and the second fastening plate 12 support the connecting rod through the through holes 13, so that the connecting rod is connected to the external fixed point. The top plate 25 is provided with the same connecting holes 14, openings and arc-shaped plates 3 as the first fastening plate 11 and the second fastening plate 12. Further, it is convenient to connect another set of bolts. The connecting holes 14 on the top plate 25 are arranged perpendicular to the axis of the through holes 13. When bolts are installed on the top plate 25, the connecting rod can be locked and loosened by adjusting the tightness of the bolts, which is conducive to improving the connection stability between the connecting rod and the tiger card.

[0047] The implementation principle of Embodiment 1 is as follows: When fixing the tiger card body, the external fixed point is placed in the avoidance groove, and any one of the connecting holes 14 on the first fastening plate 11 or the second fastening plate 12 is aligned with the bolt. Rotate the bolt so that the thread teeth are screwed into along the opening. Rotate the bolt until the side of the thread teeth along the axis direction of the bolt contacts the arc-shaped plate 3. At this time, part of the thread teeth of the bolt are in threaded engagement with the arc-shaped plate 3. Continuously rotate the bolt, and then the bolt moves along the axis direction, which is convenient to clamp and position the external fixed point through the bolt. The thickness of the arc-shaped plate 3 gradually increases along the extension direction away from the screwing-in edge 15, which is suitable for bolts with different pitches and is conducive to improving the use convenience of the tiger card. Embodiment

[0048] Referring to Figure 3 , the difference between this embodiment and Embodiment 1 is that a sleeve plate is arranged on the outside of the second fastening plate 12. The sleeve plate includes a supporting part 41 and two side plates 42. The two side plates 42 are respectively vertically and fixedly connected to both sides of the supporting part 41 along the width direction, and the distance between the two side plates 42 is adapted to the distance between the mutually separated surfaces of the first connecting plate 21 and the second connecting plate 22.

[0049] On the sides of the first connecting plate 21 and the second connecting plate 22 that are away from each other, positioning blocks 26 are fixedly connected. The positioning blocks 26 are integrally formed with the corresponding first connecting plate 21 or second connecting plate 22 and are formed by stamping. The side plate 42 is provided with a positioning groove 421 adapted to the positioning block 26. The second fastening plate 12 is clamped between the two side plates 42, and the supporting part 41 is pushed in the direction close to the second fastening plate 12. Both the side plate 42 and the supporting plate are made of elastic metal. An arc-shaped guiding surface is provided on the side of the positioning block 26 away from the first fastening plate 11. When the supporting part 41 is pushed, the side plate 42 moves along the arc-shaped guiding surface and gradually deforms until the positioning groove 421 is aligned with the positioning block 26, at which time the side plate 42 resets, enabling the positioning block 26 to be inserted into the positioning groove 421. At this time, the positioning block 26 limits the side plate 42 and makes the supporting part 41 fit with the second fastening plate 12.

[0050] The supporting part 41 is transversely provided with a round hole communicating with the connecting hole 14. The diameter of the round hole is larger than that of the connecting hole 14. One end of the supporting part 41 away from the second fastening plate 12 is rotatably connected with a moving ring 43 centered on the axis of the round hole. The moving ring 43 is provided with an abutting rod 431. The abutting rod 431 is arranged radially along the moving ring 43, and the abutting rod 431 passes through the moving ring 43 along its own axis and is threadedly connected with the moving ring 43. When the moving ring 43 rotates, it drives the abutting rod 431 to move. When the threaded rod is in threaded cooperation with a part of the arc-shaped plate 3, a gap is formed between the other side of the threaded rod and the inner wall of the connecting hole 14. The moving ring 43 is rotated to make the abutting rod 431 at the maximum gap between the bolt and the inner wall of the connecting hole 14.

[0051] The abutting rod 431 is rotated. Under the supporting action of the moving ring 43, the abutting rod 431 abuts against the bolt and pushes the bolt to fit with the arc-shaped plate 3, which is beneficial to improving the connection stability between the bolt and the arc-shaped plate 3. At the same time, it is applicable to bolts of different diameters, further improving the use convenience. The sleeve plate is separately provided from the tiger clamp and is supported by a post-assembly method. When the diameter of the bolt is adapted to the diameter of the connecting hole 14, there is no need to assemble the sleeve plate, further improving the use convenience. Embodiment

[0052] Referring to Figure 4 , the difference between this embodiment and Embodiment 1 is that the forming method of the arc-shaped plate 3 is different. In this embodiment, both the first fastening plate 11 and the second fastening plate 12 are provided with connecting holes 14 and openings. On the sides of the first fastening plate 11 and the second fastening plate 12 that are close to each other, there are abutting plates 5. The abutting plates 5 are in contact with the corresponding first fastening plate 11 and second fastening plate 12. Both the first fastening plate 11 and the second fastening plate 12 are fixedly provided with supporting blocks 16 adapted to the abutting plates 5. The abutting plates 5 are located between the multiple supporting blocks 16 and are in contact with the supporting blocks 16. The multiple supporting blocks 16 cooperate to limit the rotation of the abutting plates 5 in the vertical direction.

[0053] The abutment plate 5 is provided with a mounting hole 51 communicating with the connection hole 14, and a screw-in opening 52 corresponding to the opening. The arc plate 3 is located on the side of the abutment plate 5 away from the corresponding fastening plate 1 11 or fastening plate 2 12. The diameter of the connection hole 14 is larger than the diameter of the mounting hole 51. When installing the bolt, the bolt is passed through the connection hole 14 and threadedly matched with the arc plate 3 on the abutment plate 5, so that the bolt is conveniently used to clamp and position the external fixing point in the avoidance opening 23. The abutment plate 5 can be disassembled and replaced, which further expands the scope of application and improves the convenience of use.
