Technical Field

[0001] This application relates to the field of terminal clamp technology, and in particular to a multifunctional terminal clamp. Background Technology

[0002] Tensile testing machines are mechanical force-applying testing machines used to perform tensile, compression, bending, shearing, and peel tests on materials. They are suitable for testing various physical and mechanical properties of materials such as plastic sheets, pipes, profiles, plastic films, rubber, and wires and cables. They are indispensable testing equipment for material development, physical property testing, teaching research, and quality control.

[0003] In existing technologies, the material to be tested is typically hung on a connecting column on the tensile plate of a tensile testing machine. The tensile plate is moved by a motor to perform the tensile test on the material, which is a single-function device. Therefore, existing tensile testing machines lack a clamping tool for holding the material to be tested. Utility Model Content

The distance between the two slide rails gradually decreases from the inside to the outside along the radial direction of the tension plate. Two sliders are slidably connected to each of the two slide rails. Two clamping blocks are fixedly connected to each of the two sliders. When the two sliders move to the ends of the two slide rails away from the axis of the tension plate, the two clamping blocks engage. A top block is connected to the tension plate via an elastic element. The top block moves radially along the tension plate via the elastic element, and under the action of the elastic element, the top block drives the two clamping blocks to move away from the axis of the tension plate.

[0009] Preferably, each of the two clamping blocks has a second receiving groove on one side near the axis of the tension plate. The opening directions of the two second receiving grooves are opposite to each other, and the extension direction of the two second receiving grooves is the same as the radial direction of the tension plate. Each of the two second receiving grooves is connected to the first receiving groove of the corresponding clamping block. When the two clamping blocks are joined together, the elastic element is located in both of the second receiving grooves.

[0010] Preferably, both clamping blocks have teeth on their opposite sides.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application provides a further detailed description. An embodiment of this application discloses a multifunctional terminal clamp, including a tension plate 1 with a connecting post on its upper surface. A receiving groove is formed on the side of the tension plate 1, with the opening direction of the groove being the same as the radial direction of the tension plate 1, for placing the clamped portion of a terminal 10 to be tested into the receiving groove. Two slide rails 2 are symmetrically arranged on both sides of the upper surface of the tension plate 1 in the direction of the receiving groove opening. The distance between the two slide rails 2 gradually decreases from the inside to the outside along the radial direction of the tension plate 1. Two sliders 3 are slidably connected to each of the two slide rails 2, and two clamping blocks 4 are fixedly connected to each of the two sliders 3. When the two sliders 3 move to the ends of the two slide rails away from the axis of the tension plate 1, the two clamping blocks 4 engage together, thus clamping the terminal 10 to be tested. The tension plate 1 is connected to a top block 6 via an elastic element 5. The top block 6 moves radially along the tension plate 1 via the elastic element 5. Under the action of the elastic element 5, the top block 6 drives the two clamping blocks 4 to move away from the axis of the tension plate 1. Through the elasticity of the elastic element 5, the top block 6 is pushed to move radially away from the axis of the tension plate 1, thereby causing the two clamping blocks 4 to automatically assemble together under the guidance of the slide rail 2, achieving the clamping effect of the terminal 10 of the material to be tested between the two clamping blocks 4.

[0023] Furthermore, a baffle 7 is fixedly connected to the upper surface of the tension plate 1. The baffle 7 is located above the two clamping blocks 4 and is used to limit the position of the two clamping blocks 4, prevent the two clamping blocks 4 from moving away from the tension plate 1 along the axial direction of the tension plate 1, and ensure that the two sliders 3 are always in the two slide rails 2 respectively.

[0024] Furthermore, the upper surface of the tension plate 1 is provided with a protective seat 8 around the two clamping blocks 4, and the baffle 7 is fixedly connected to the protective seat 8, so that the two clamping blocks 4 are surrounded by the protective seat 8 to protect the two clamping blocks 4.

[0025] Furthermore, the baffle 7 has a groove at the position corresponding to the receiving groove, so that when the material to be tested is placed into the receiving groove, the axial angle of the tension plate 1 will not be obstructed by the baffle 7.

[0026] Furthermore, the upper surface of the tension plate 1 is fixedly provided with a first manual control connecting post 101, and the top block 6 is fixedly provided with a second manual control connecting post 601. It also includes a wrench lever 9, one end of which is rotatably connected to the first manual control connecting post 101, and the middle part of which is rotatably connected to the second manual control connecting post 601. This allows the wrench lever 9 to rotate around the first manual control connecting post 101, thereby moving the top block 6 and manually controlling it to move closer to the axis of the tension plate 1, releasing the clamping state of the two clamping blocks 4.

[0027] Furthermore, each of the two clamping blocks 4 is provided with a first receiving groove 401. The opening directions of the two first receiving grooves 401 are opposite to each other, and the extension direction of the two first receiving grooves 401 is perpendicular to the upper surface of the tension plate 1. When the two clamping blocks 4 are joined together, the top block 6 is simultaneously located in both first receiving grooves 401. When the top block 6 moves radially away from the axis of the tension plate 1, it can simultaneously push the two clamping blocks 4 to move. Moreover, after the two clamping blocks 4 are joined together, the top block 6 is simultaneously located in both first receiving grooves 401, which will not interfere with the fully joined state of the two clamping blocks 4; and when the top block 6 moves radially towards the axis of the tension plate 1, it can also simultaneously pull the two clamping blocks 4 to move, so that the two clamping blocks 4 are disengaged from the clamped joined state.

[0028] Furthermore, the elastic element 5 can be connected to the top block 6 at any position that does not obstruct the two clamping blocks 4. In this embodiment, each of the two clamping blocks 4 has a second receiving groove 402 on the side near the axis of the tension plate 1. The opening directions of the two second receiving grooves 402 are opposite to each other, and the extending direction of the two second receiving grooves 402 is the same as the radial direction of the tension plate 1. Each of the two second receiving grooves 402 is connected to the first receiving groove 401 of the corresponding clamping block 4. When the two clamping blocks 4 are assembled together, the elastic element 5 is simultaneously located in the two second receiving grooves 402 and extends into the first receiving grooves 401 of the two clamping blocks 4 to connect with the top block 6.

[0029] Furthermore, both clamping blocks have teeth on opposite sides in the four directions to increase friction and improve the clamping effect.

[0030] Furthermore, the types of slide rail 2 and slider 3, as well as the sliding connection method, can employ any conventional technical means. In this embodiment, slide rail 2 is a concave strip-shaped groove opened on the upper surface of tension plate 1, and slider 3 is a cylindrical pin perpendicular to the upper surface of tension plate 1. The end of the cylindrical pin passes through clamping block 4 and protrudes from clamping block 4, located in the concave strip-shaped groove. Combined with the limiting and blocking pin of baffle 7, one end of the cylindrical pin is always located in the strip-shaped groove, and the radial movement position of the pin is guided by the side of the concave strip-shaped groove.

[0031] Furthermore, the elastic element 5 is a compression spring, one end of which is fixedly connected to the tension plate 1, and the other end of which is fixedly connected to the top block 6. The compression spring always pushes the top block 6 radially away from the axis of the tension plate 1. To maintain the direction of the spring force, the compression spring can be sleeved outside the guide post composed of two clearance-fitted tubes, or it can be set inside the guide post composed of two clearance-fitted tubes.

[0032] Working principle: Pushing the wrench lever 9 causes it to rotate around the first hand-controlled connecting post 101. The wrench lever 9, through the second hand-controlled connecting post 601, drives the top block 6 to move closer to the axis of the tension plate 1. During the movement of the top block 6, it drives the two clamping blocks 4 to move towards the axis of the tension plate 1, and the two clamping blocks 4 separate under the guidance of the two slide rails 2. Place the material terminal 10 to be tested between the two clamping blocks 4, and release the push lever. Under the push of the elastic element 5, the top block 6 is pushed away from the axis of the tension plate 1, and the top block 6 drives the two clamping blocks 4 to move radially away from the axis of the tension plate 1. Under the guidance of the two slide rails 2, the two clamping blocks 4 gradually approach and clamp the material terminal 10 to be tested. During the process of the tension plate 1 pulling the terminal 10 of the material to be tested, the two clamping blocks 4 gradually move away from the axis of the tension plate 1 and move closer to each other as the tension plate 1 is pulled. The further the tension plate 1 moves away from the terminal 10 of the material to be tested, the tighter the two clamping blocks 4 clamp, which significantly improves the clamping effect of the two clamping blocks 4.
