DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0028] The embodiment of the present application discloses a toothed tiger card and a production process thereof.

[0029] Example 1: Reference Figure 1 and Figure 2 A toothed tiger clamp comprises two mutually parallel locking plates 1, the two locking plates 1 are respectively set as a fastening plate 11 and a fastening plate 2 12, a connecting plate 1 21 is fixedly connected between the fastening plate 1 11 and the fastening plate 2 12, the connecting plate 1 21 is located on the same side of the fastening plate 1 11 and the fastening plate 2 12 along the width direction, and the connecting plate 1 21, the fastening plate 1 11 and the fastening plate 2 12 are integrally formed. A connecting plate 2 22 is fixedly connected to the side of the fastening plate 2 12 away from the connecting plate 1 21, the connecting plate 2 22 is parallel to the connecting plate 1 21, and a plurality of slots 221 are opened on the side of the connecting plate 2 22 away from the fastening plate 2 12, a clamping plate 111 corresponding to the slots 221 is fixedly connected to the side of the fastening plate 1 11 away from the connecting plate 1 21, and the clamping plate 111 passes through the slots 221 and is clamped with the connecting plate 2 22.

[0030] Reference Figure 1 and Figure 2 A top plate 25 is fixedly connected to one side of the connecting plate 21 along the width direction, and the top plate 25 is bent in the direction close to the connecting plate 21, and the side of the top plate 25 close to the connecting plate 21 is located between the fastening plate 11 and the fastening plate 12, and the fastening plate 11 and the fastening plate 12 are both in contact with the top plate 25. The top plate 25 supports and limits the fastening plate 11 and the fastening plate 12, which is beneficial to improve the connection strength between the fastening plate 11 and the fastening plate 12.

[0031] Reference Figure 1 and Figure 2, the connecting plate 1 21, the top plate 25, the connecting plate 2 22, the fastening plate 1 11 and the fastening plate 2 12 are integrally formed from the same metal sheet and processed by bending. The fastening plate 1 11 and the fastening plate 2 12 are both provided with a through hole 13 on one side close to the top plate 25, and the two through holes 13 are coaxial with each other. The fastening plate 1 11 and the fastening plate 2 12 are both provided with a connecting hole 14 on one end away from the through hole 13, and the fastening plate 1 11 and the fastening plate 2 12 are both provided with an opening connected to the connecting hole 14, and one side of the opening is arranged along the diameter direction of the connecting hole 14, and this side is arranged as a screw-in edge 15. The outer circle of the connecting hole 14 is arranged in an involute from the center of the circle, and an arc plate 3 is arranged along the circumference of the connecting hole 14. In this embodiment, the arc plate 3 is formed by bending the side of the inner wall of the connecting hole 14 toward the connecting plate 21, and one end of the arc plate 3 close to the center of the connecting hole 14 is close to one end of the screw-in edge 15 close to the connecting hole 14.

[0032] Reference Figure 1 and Figure 2 When the tiger clip needs to be fixed, align the avoidance opening 23 with the external fixing point, so that the external fixing point enters into the avoidance opening 23, and the external fixing point is opposite to the connecting hole 14. The connecting hole 14 is used to install the bolt. It should be noted that the external thread on the bolt is formed by spirally arranged screw teeth, and the distance between adjacent screw teeth is the pitch. When installing the bolt, align the bolt with the connecting hole 14, and let the head end of the screw tooth pass through the connecting hole 14 from the opening. It should be noted that the width of the screw-in edge 15 is smaller than the pitch of the bolt, so that the fallen leaves do not interfere with the screw-in edge 15 when passing through the opening.

[0033] Reference Figure 1 and Figure 2 Since the side of the connecting hole 14 is involute, the thickness of the arc plate 3 gradually increases in the direction away from the screw-in edge 15, and the direction of the arc plate 3 away from the screw-in edge 15 is the same as the rotation direction when the bolt is screwed in. When the bolt is turned, the thread extends along the length of the arc plate 3. For the entire arc plate 3, there is a region where the thickness is adapted to the pitch of the bolt, and the thread contacts the arc plate 3 here. At this time, the arc plate 3 is located between two threads, so that the arc plate 3 and part of the thread of the bolt are threaded together. The thickness of the arc plate 3 is gradually changed, so that it is easy to match with bolts with different pitches, thereby improving the convenience of use.

[0034] Reference Figure 1 and Figure 2, under the action of the arc plate 3, when the bolt continues to rotate, the bolt approaches the external fixed point in the avoidance opening 23 along its own axial direction, and when the bolt contacts the external fixed point, the external fixed point is clamped and positioned. Further, a plurality of tooth blocks 24 are arranged in the avoidance opening 23, and the tooth blocks 24 are arranged along the length direction of the fastening plate 11, and the tooth blocks 24 are fixedly connected to the corresponding connecting plate 1 21 or connecting plate 2 22. When the bolt is pressed against the external fixed point, the tooth block 24 is located on the side of the external fixed point away from the bolt, which is conducive to improving the connection stability between the tiger clamp and the external fixed point.

[0035] Reference Figure 1 and Figure 2 When using the tiger clamp, another external connecting part is connected through the circular hole. Taking the connecting rod as an example, the connecting rod is passed through the two through holes 13 in sequence. The fastening plate 11 and the fastening plate 2 12 support the connecting rod through the through hole 13, so that the connecting rod is connected to the external fixed point. The top plate 25 is provided with the same connecting hole 14, opening and arc plate 3 as the fastening plate 1 11 and the fastening plate 2 12. In order to facilitate the connection of another set of bolts, the connecting hole 14 on the top plate 25 is arranged perpendicular to the axis of the through hole 13. When the bolts are installed on the top plate 25, the locking and loosening of the connecting rod can be achieved by adjusting the tightness of the bolts, which is conducive to improving the connection stability between the connecting rod and the tiger clamp.

[0036] 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 the bolt is directly opposite to any one of the connection holes 14 on the fastening plate 11 or the fastening plate 2 12. The bolt is turned to screw the thread in along the opening, and the bolt is turned until the thread contacts the arc plate 3 along the side of the bolt axis direction, at which time part of the thread of the bolt completes the thread fit with the arc plate 3, and the bolt is continuously turned to move the bolt along the axis direction, so as to facilitate the clamping and positioning of the external fixed point by the bolt. The thickness of the arc plate 3 gradually increases along the extension direction of the arc plate 3 away from the screw-in edge 15, so as to be suitable for bolts with different pitches, which is conducive to improving the convenience of use of the tiger card.

[0037] Example 2: Reference Figure 3 The difference between this embodiment and embodiment 1 is that a sleeve plate is arranged on the outer side of the fastening plate 2 12, and the sleeve plate includes a support portion 41 and two side plates 42, and the two side plates 42 are respectively vertically fixedly connected to the two sides of the support portion 41 along the width direction, and the spacing between the two side plates 42 is adapted to the distance between the two sides of the connecting plate 1 21 and the connecting plate 22 that are away from each other.

[0038] The side surfaces of the connecting plate 1 21 and the connecting plate 2 2 that are away from each other are fixedly connected with positioning blocks 26. The positioning blocks 26 are integrally formed with the corresponding connecting plate 1 21 or the connecting plate 2 2 and are formed by stamping. The side plate 42 is provided with positioning grooves 421 adapted to the positioning blocks 26. The fastening plate 2 12 is inserted between the two side plates 42, and the support portion 41 is pushed toward the fastening plate 2 12. The side plate 42 and the support plate are both made of elastic metal. The side of the positioning block 26 that is away from the fastening plate 1 11 is provided with an arc guide surface. When the support portion 41 is pushed, the side plate 42 moves along the arc guide surface and gradually deforms until the positioning groove 421 is directly opposite to the positioning block 26. The side plate 42 is reset, so that the positioning block 26 is inserted into the positioning groove 421. At this time, the positioning block 26 limits the side plate 42 and makes the support portion 41 fit with the fastening plate 2 12.

[0039] The support portion 41 is provided with a circular hole in the transverse direction and connected to the connecting hole 14. The diameter of the circular hole is larger than the diameter of the connecting hole 14. The end of the support portion 41 that is away from the fastening plate 12 is connected to a movable ring 43 that is rotatably centered around the circular hole axis. The movable ring 43 is provided with an abutment rod 431, which is arranged radially along the movable ring 43, and the abutment rod 431 passes through the movable ring 43 along its own axial direction and is threadedly connected to the movable ring 43. When the movable ring 43 rotates, the abutment rod 431 is driven to move. When the threaded rod is threadedly matched with a part of the arc-shaped plate 3, a gap is formed between the other side thereof and the inner wall of the connecting hole 14. The movable ring 43 is rotated so that the abutment rod 431 is located at the maximum gap between the bolt and the inner wall of the connecting hole 14.

[0040] The abutment rod 431 is rotated, and under the support of the moving ring 43, the abutment rod 431 abuts against the bolt, and pushes the bolt to fit with the arc plate 3, which is conducive to improving the connection stability between the bolt and the arc plate 3, and is suitable for bolts of different diameters, further improving the convenience of use. The sleeve plate and the tiger clamp are separately arranged and supported by post-assembly. When the bolt diameter is adapted to the diameter of the connection hole 14, there is no need to assemble the sleeve plate, which further improves the convenience of use.

[0041] Example 3: Reference Figure 4 The difference between this embodiment and the embodiment 1 is that the arc-shaped plate 3 is formed in a different manner. In this embodiment, the fastening plate 1 11 and the fastening plate 2 12 are both provided with a connection hole 14 and an opening. The fastening plate 1 11 and the fastening plate 2 12 are both provided with abutment plates 5 on the side close to each other. The abutment plates 5 are fitted with the corresponding fastening plates 1 11 and the fastening plates 2 12. The fastening plates 1 11 and the fastening plates 2 12 are both fixed with support blocks 16 adapted to the abutment plates 5. The abutment plates 5 are located between the plurality of support blocks 16 and abut against the support blocks 16. The plurality of support blocks 16 cooperate to limit the rotation of the abutment plates 5 in the vertical direction.

[0042] 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 mounting plate, 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.

[0043] The present application also discloses a production process of a toothed tiger card, comprising the following steps: Material preparation: Use metal sheets to make tiger card sheet raw materials by stamping or cutting; Edge cutting: cutting the side edge of the raw material of the tiger card sheet so that the side edge corresponding to the raw material forms a tooth block 24; Punching 1: Punching the tiger card sheet material to form a through hole 13; Punching 2: using another set of punching tools to perform secondary punching to form the connecting hole 14 and the opening; Flanging: The raw material of the tiger card sheet is extruded by stamping to form a curved sheet 3; Bending: Use a bending machine to bend the raw material of the tiger card sheet to form the tiger card; Post-processing: Check the bent slot card to remove burrs and flash.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
