Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a quick clamping device suitable for carbon fiber carrier plates. Background Art

[0002] In the application of carbon fiber plate (CFPR plate) anchors, common types include flat anchors and clip anchors. The performance of flat anchors, especially in terms of bearing capacity and critical length, is very sensitive to interface compressive stress and clip thickness. For clip anchors, the stiffness of the clip is key. It must be sufficient to firmly clamp the CFPR plate and reduce slippage during the anchoring process, thereby improving the efficiency of the anchor. Traditional clip anchors are mainly composed of two parts: an anchor plate and a clip. Its self-anchoring function allows the CFPR plate to slide with the clip when subjected to lateral tension and be squeezed inside the anchor plate to provide a larger prestress. In the field of rapid clamping reinforcement, bolt tightening is a commonly used method. For example, in the carbon fiber plate mechanical clamping anchor and reinforcement device described in Chinese patent CN205743030U, the upper anchor block and the lower anchor block are fixedly connected by high-strength bolts. However, this method requires tightening four bolts, so there is still room for improvement in the efficiency of rapid clamping. To improve efficiency, it is possible to consider simplifying the fastening steps or adopting a more efficient clamping mechanism to reduce construction time and improve the convenience of reinforcement operations. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a quick clamping device suitable for carbon fiber carrier plates, which can further improve the clamping efficiency.

[0004] The utility model provides a quick clamping device for a carbon fiber carrier plate, comprising: a base, a first clamping portion, a second clamping portion, and a movable rod; the second clamping portion is fixed to the base; the middle portion of the movable rod is hinged to the base, one end of which is fixedly provided with the first clamping portion, and the other end of which is provided with a driving member, the driving member being used to move the movable rod to cause the first clamping portion and the second clamping portion to open and close with each other;

[0005] The first clamping portion and the second clamping portion are respectively provided with wedge-shaped grooves on opposite sides, and a pair of wedge-shaped clips are respectively provided in the middle and are arranged opposite to each other and fit with the wedge-shaped grooves; the pair of wedge-shaped clips are used to clamp the carbon fiber carrier plate; the contact points between the wedge-shaped clips and the clamping portions are respectively provided with a plurality of first protrusions and a plurality of first grooves that fit with the first protrusions.

[0006] In the above-mentioned technical solution, the device consists of four main components: a base, a first clamping section, a second clamping section, and a movable rod. The second clamping section is fixed to the base, providing a stable reference frame for the clamping process, ensuring operational stability and reliability. The movement of the movable rod controls the opening and closing of the first and second clamping sections, thereby enabling rapid clamping of the carbon fiber carrier. The middle portion of the movable rod is connected to the base via a hinge. The first clamping section is fixed to one end, and the other end is equipped with a drive element. This design enables the movable rod to move in response to the drive element, thereby adjusting the relative position of the first and second clamping sections to achieve clamping. The first and second clamping sections are each provided with a wedge-shaped groove on opposite sides, with a pair of wedge-shaped clips positioned in between, matching the wedge grooves. This design enables the wedge clips to tightly grip the carbon fiber carrier, providing stable clamping force. In addition, the cooperation between the first protrusion and the first groove at the contact point between the wedge-shaped clip and the clamping part effectively reduces the slippage of the carbon fiber carrier during the anchoring process, thereby improving the efficiency of the anchor. This design draws on the self-anchoring function of traditional clip-type anchors, providing a large prestress through friction and extrusion, thereby enhancing the stability and reliability of clamping. Compared with traditional bolt fastening methods, this quick clamping device reduces the number of fastening bolts used, thereby significantly improving the clamping efficiency. This has significant advantages in increasing construction speed and reducing labor intensity. The design of the carbon fiber carrier quick clamping device fully considers the stability, efficiency and ease of operation of the clamping, and through innovative structural design, it improves the clamping efficiency and construction speed of the carbon fiber carrier.

[0007] In some embodiments, the first clamping portion and the movable rod are integrally formed, and the end of the movable rod connected to the first clamping portion is L-shaped; the connection center point of the first clamping portion and the movable rod coincides with the center point of the first clamping portion or is above the first clamping portion on the side away from the hinge point.

[0008] In this technical solution, integrated molding eliminates joint interfaces in the structure, enhancing the overall strength of the component. This lack of potential weak points at the joints ensures the structure maintains its stability and reliability even when subjected to high loads or repeated use.

[0009] In some embodiments, the contact surfaces of the first clamping portion and the second clamping portion are respectively provided with a plurality of second grooves and a plurality of second protrusions that fit with the second grooves.

[0010] In this technical solution, the interlocking relationship between the second protrusion and the second groove provides additional frictional resistance, significantly enhancing the carbon fiber carrier's ability to resist slippage when subjected to external forces. Furthermore, the synergistic action of the first and second clamping parts achieves precise positioning, ensuring proper alignment of the carbon fiber carrier during installation, thereby ensuring precise structural fit and functional integrity. This not only enhances clamping stability but also improves the efficiency and accuracy of the assembly process.

[0011] In some embodiments, the first groove includes, in sequence along the first direction, a first wall perpendicular to the first direction, a second wall parallel to the first direction, and a third wall.

[0012] In the above technical solution, the first wall is aligned perpendicular to the first direction (i.e., the direction of tension), providing critical lateral support for the structure. This arrangement helps to resist deformation or displacement caused by tension, thereby maintaining the integrity of the structure. The design of the first groove further enhances lateral support and stability in the direction of tension.

[0013] In some embodiments, the wedge angle θ of the wedge-shaped clip is 2° to 5°;

[0014] The ratio of the length of the first protrusion to the length of the wedge-shaped clip is 1:1.1-1.3;

[0015] The height of the first protrusion is greater than the depth of the first groove.

[0016] In the above-mentioned technical solution, the wedge angle θ of the wedge-shaped clip is precisely set between 2° and 5° in the clamping mechanism design. This angle range is selected to achieve a gradual increase in clamping force, avoiding sudden high pressure on the carbon fiber carrier, thereby reducing the risk of damage. Furthermore, this smaller angle helps maintain stability and even force distribution during the clamping process. The length ratio of the first protrusion to the wedge-shaped clip is designed to be within the range of 1:1.1 to 1.3, with the first protrusion slightly shorter than the wedge-shaped clip. This design ensures that the first protrusion fits perfectly within the first groove while allowing for adjustment to accommodate carbon fiber carriers of varying sizes. The height of the first protrusion is greater than the depth of the first groove, ensuring that the first protrusion fully embeds within the first groove, providing stable support and clamping force. The height difference also helps distribute pressure during the clamping process, reducing localized stress concentration on the carbon fiber carrier, thereby improving the overall performance of the clamping structure and the safety of the carbon fiber carrier.

[0017] In some embodiments, the driving member is rotatably disposed on the base, and the driving member is provided with an inclined surface and a plane smoothly transitioning from the inclined surface, and the inclined surface abuts against one end of the movable rod.

[0018] In the above technical solution, the driving member is rotatably arranged on the base, and the driving member is provided with an inclined surface, which abuts against one end of the movable rod. This design can use the wedge principle to realize the clamping action. The inclined surface can be an inclined surface or a slope. Its function is to move the movable rod along the inclined surface through the push or pull force of the inclined surface on the movable rod when the driving member rotates. One end of the movable rod can slide along the inclined surface, thereby realizing the opening and closing control of the first clamping part and the second clamping part. The design of the inclined surface can make this clamping action more stable and controllable, and reduce the impact and vibration during the clamping process. The design of the inclined surface can improve the efficiency of the clamping action, because the rotation of the driving member can be directly converted into the linear motion of the movable rod.

[0026] The utility model provides a fast clamping device suitable for a carbon fiber carrier plate, which can further improve the clamping efficiency.

[0027] Example 1

[0028] See also Figure 1 A quick clamping device for carbon fiber carrier plates comprises: a base 1, a first clamping part 2, a second clamping part 4 and a movable rod 3; the second clamping part 2 is fixed to the base 1; the middle part of the movable rod 3 is hinged to the hinge part 9 on the base by a pin 8, one end of which is fixed with the first clamping part 2, and the other end is equipped with a driving member 10, the driving member 10 is used to move the movable rod 3, so that the first clamping part 2 and the second clamping part 4 are opened and closed with each other; the first clamping part 2 and the movable rod 3 are integrally formed, and the end of the movable rod 3 connected to the first clamping part 2 is L-shaped, so that the axis of the movable rod 3 is perpendicular to the end face of the first clamping part 2; the center point of the connection between the first clamping part 2 and the movable rod 3 coincides with the center point of the first clamping part 2 or is above the first clamping part 2 on the side away from the hinge point. The integral molding eliminates the connection interface in the structure and enhances the overall strength of the component. Due to the lack of potential weaknesses in the connection, this technology ensures that the structure can maintain its stability and reliability when subjected to high loads or repeated use.

[0029] See also Figure 2The first clamping portion 2 and the second clamping portion 4 are provided with wedge-shaped grooves 22 and 42 on opposite sides, respectively, and a pair of wedge-shaped clips 5 and 6 are positioned in between, correspondingly engaging with the wedge-shaped grooves. The pair of wedge-shaped clips 5 and 6 are used to clamp the carbon fiber carrier A. The contact areas between the wedge-shaped clips 5 and 6 and the clamping portions 2 and 4 are provided with a plurality of first protrusions 51 and 61, respectively, and a plurality of first grooves 23 and 43 engaging with the first protrusions 51 and 61. The contact surfaces between the first clamping portion 2 and the second clamping portion 4 are provided with a plurality of second grooves 21 and a plurality of second protrusions 41 engaging with the second grooves 21. The interlocking relationship between the second protrusions and the second grooves provides additional frictional resistance, significantly enhancing the carbon fiber carrier's ability to resist slippage when subjected to external forces. Furthermore, the synergistic effect of the first and second clamping portions enables precise positioning, ensuring the correct alignment of the carbon fiber carrier during installation, thereby ensuring precise structural fit and functional integrity. This not only enhances the stability of the clamping, but also improves the efficiency and accuracy of the assembly process. In this embodiment, the first groove includes a first wall 210 perpendicular to the first direction G, a second wall 211 parallel to the first direction G, and a third wall 212 along the first direction. The first wall is arranged perpendicular to the first direction (i.e., the direction of tension), providing critical lateral support for the structure. This layout helps to resist deformation or displacement caused by tension, thereby maintaining the integrity of the structure. The design of the first groove further enhances lateral support and stability in the direction of tension.

[0030] See also Figure 3 The wedge angle θ of the wedge-shaped clips 5 and 6 is 2° to 5°, preferably 2.5°. The ratio of the length w of the first protrusions 51 and 61 to the length W of the wedge-shaped clips 5 and 6 is 1:1.1 to 1.3, preferably 1:1.2. The height of the first protrusions 51 and 61 is greater than the depth of the first grooves 23 and 43. In the design of the clamping mechanism, the wedge angle θ of the wedge-shaped clips is precisely set between 2° and 5°. This angle range is selected to achieve a gradual increase in clamping force, avoiding sudden high pressure on the carbon fiber carrier and reducing the risk of damage. Furthermore, this smaller angle helps maintain stability and even force distribution during the clamping process. The length ratio of the first protrusion to the wedge-shaped clip is designed to be between 1:1.1 and 1.3, with the first protrusion slightly shorter than the wedge-shaped clip. This design ensures that the first protrusion fits perfectly in the first groove while allowing for sufficient adjustment to accommodate carbon fiber carriers of varying sizes. The height of the first protrusion is greater than the depth of the first groove, ensuring that the first protrusion can be fully embedded in the first groove, providing stable support and clamping force. The height difference also helps to disperse pressure during the clamping process, reducing localized stress concentration on the carbon fiber carrier, thereby improving the overall performance of the clamping structure and the safety of the carbon fiber carrier.

[0031] See also Figure 1 and Figure 4 、 Figure 5 The driving member 10 is rotatably arranged on the base 1. The driving member 10 is provided with an inclined surface 101 and a plane 102 that smoothly transitions to the inclined surface 101. The inclined surface 101 abuts against one end of the movable rod 3. In this embodiment, the driving member 10 is a rotatable cylinder with a rotating handle 103. This solution can also be carried out electrically. The height of the cylinder can be set according to actual needs, such as different applied loads. At the same time, the load can be obtained according to calculations, which will not be repeated here. The driving member is rotatably arranged on the base. The driving member is provided with an inclined surface. This inclined surface abuts against one end of the movable rod. This design can utilize the wedge principle to achieve a clamping action. The inclined surface can be an inclined surface or a slope. Its function is that when the driving member rotates, the movable rod is pushed or pulled by the inclined surface. One end of the movable rod can slide along the inclined surface, thereby achieving the opening and closing control of the first clamping part and the second clamping part. The inclined surface design can make the clamping action more stable and controlled, reducing shock and vibration during the clamping process. The inclined surface design can improve the efficiency of the clamping action because the rotation of the driving member can be directly converted into linear motion of the movable rod.

[0032] Please refer to the usage process Figure 5 After the carbon fiber carrier is clamped by the wedge-shaped clamps 5 and 6, it is pre-tightened by the first clamping part 2 and the second clamping part 4, and then the driving part 10 is rotated by turning the handle 103 so that one end of the movable rod 3 slowly and smoothly transitions to the plane 102, so that the movable rod 3 remains fixed, and the clamping is completed. Compared with the traditional method of tightening four bolts, this solution is more efficient and convenient. At the same time, the length of the movable rod 3 at both ends before and after the hinge point and the height of the driving part 10 can be set according to different load requirements to meet different clamping force requirements. At the same time, since the end of the movable rod 3 connected to the first clamping part 2 is L-shaped, the axis of the movable rod 3 is perpendicular to the end face of the first clamping part 2; the center point of the connection between the first clamping part 2 and the movable rod 3 coincides with the center point of the first clamping part 2 or is above the first clamping part 2 on the side away from the hinge point, so that after pressing and fixing, the overall force of the carbon fiber carrier is more uniform and not easy to break.

[0033] The device of the utility model consists of four main components: a base, a first clamping part, a second clamping part, and a movable rod. The second clamping part is fixed to the base, providing a stable reference frame for the clamping process, ensuring operational stability and reliability. The movement of the movable rod controls the opening and closing of the first and second clamping parts, thereby achieving rapid clamping of the carbon fiber carrier. The middle part of the movable rod is connected to the base via a hinge, with the first clamping part fixed to one end and a drive element installed at the other end. This design enables the movable rod to move accordingly under the action of the drive element, thereby adjusting the relative position of the first and second clamping parts to achieve the clamping action. Wedge-shaped grooves are provided on opposite sides of the first and second clamping parts, and a pair of wedge-shaped clips are arranged in the middle, matching the wedge grooves. This design enables the wedge clips to tightly clamp the carbon fiber carrier and provide stable clamping force. In addition, the cooperation between the first protrusion and the first groove at the contact point between the wedge-shaped clip and the clamping part effectively reduces the slippage of the carbon fiber carrier during the anchoring process, thereby improving the efficiency of the anchor. This design draws on the self-anchoring function of traditional clip-type anchors, providing a large prestress through friction and extrusion, thereby enhancing the stability and reliability of clamping. Compared with traditional bolt fastening methods, this quick clamping device reduces the number of fastening bolts used, thereby significantly improving the clamping efficiency. This has significant advantages in increasing construction speed and reducing labor intensity. The design of the carbon fiber carrier quick clamping device fully considers the stability, efficiency and ease of operation of the clamping, and through innovative structural design, it improves the clamping efficiency and construction speed of the carbon fiber carrier.
