Also, the use of the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.
First, a collet of a tension meter according to an embodiment of the first aspect of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-2, the chuck of the tension meter according to the embodiment of the first aspect of the present invention includes a cover plate 1, a base plate 2, and a hook 3. The left end and the right end of the cover plate 1 are provided with first connecting parts 4, and the front end of the lower side surface of the cover plate 1 is formed into a first clamping surface; the left end and the right end of the bottom plate 2 are provided with second connecting parts 5, the front end of the upper side surface of the bottom plate 2 is formed into a second clamping surface, and the first connecting part 4 and the second connecting part 5 are matched with each other to enable the first clamping surface of the bottom plate 2 and the second clamping surface of the cover plate 1 to clamp the surface of a coated product; the hook 3 is disposed at a rear end of the cover plate 1 and/or the base plate 2 and between the two first connection portions 4 and/or the second connection portions 5.
Most of the current manufacturers hook the small holes on the surface skin of the cladding product by using the hooks of the tensiometer, then pull the cladding product outwards, and observe the indication number of the tensiometer in the pulling process so as to judge the bonding force between the surface skin and the internal framework of the cladding product. However, if the adhesion is too high, the skin will be pulled by the hook of the tensiometer during the pulling process, which results in inaccurate tension test. Aiming at the problem, a chuck is additionally arranged between a tension meter and a surface skin, the chuck consists of a cover plate 1 and a bottom plate 2 which can be attached together, the front ends of the cover plate 1 and the bottom plate 2 are used for clamping the surface skin of a coated product, the cover plate 1 and the bottom plate 2 are clamped tightly through a first connecting part 4 and a second connecting part 5 after the clamping, the surface skin is tightly clamped between the cover plate 1 and the bottom plate 2, and finally, a hook part 3 on the cover plate 1 and the bottom plate 2 is hooked by a hook of the tension meter to carry out tension test. In the process of the tension test, the contact surface between the chuck and the surface skin of the coated product is not only concentrated in a small area, and the surface skin is widely distributed, so that the surface skin of the coated product cannot be easily damaged by the tension meter, and the test accuracy is ensured.
Further, the first clamping surface of the cover plate 1 is formed as an arc-shaped concave surface, and the second clamping surface of the base plate 2 is formed as an arc-shaped convex surface. The front ends of the cover plate 1 and the bottom plate 2 are respectively provided with a first clamping surface and a second clamping surface which are matched with each other to clamp the surface skin of the coated product. Whether the first clamping surface and the second clamping surface can clamp the skin of the coated product or not in the tensile test process is very important, so that the first clamping surface and the second clamping surface of the chuck of the tension meter are respectively designed into an arc concave surface and an arc convex surface, and the structural property increases the contact area with the skin of the coated product relative to a plane, so that the chuck and the skin of the coated product are more compact, and the situation that the skin of the coated product easily slides out of the chuck is avoided.
Furthermore, the first clamping surface of the cover plate 1 and the second clamping surface of the bottom plate 2 are both formed with anti-skid grains. The first clamping surface and the second clamping surface can also prevent the surface skin of the coated product from sliding out by increasing anti-skid lines, and the structure is simple to manufacture and has a remarkable effect.
Further, as shown in fig. 1 to 2, the hook portions 3 are two corresponding openings formed at the rear ends of the cover plate 1 and the base plate 2, respectively. The apron 1 presss from both sides tight back through first connecting portion 4 and second connecting portion 5 with bottom plate 2, and two trompils of apron 1 and bottom plate 2's rear end are linked together, consequently only need to catch on the trompil of two intercommunications with the hook of tensiometer and can carry out the tensile test, and this structure easily makes and easy and simple to handle.
Further, the hook 3 is a ring attached to the rear end of the cover plate 1 or the base plate 2. This ring can be connected on apron 1 also can be connected on bottom plate 2, only need during the tensile test with the hook of tensiometer catch on the ring can, this structure easily makes and easy and simple to handle.
Further, the rear end of the cover plate 1 is rotatably coupled to the rear end of the base plate 2. The connecting structure between the cover plate 1 and the bottom plate 2 is similar to a shell, and the structure connects two independent parts together, so that the integrity of the chuck structure is increased, and the chuck is more convenient to use and carry.
The tension meter assembly comprises a tension meter body and the chuck of the tension meter. The tension meter assembly comprises the chuck, so that the skin of the clad product can be effectively prevented from being pulled to be damaged.
Furthermore, the anti-slip sleeve is arranged on the tension meter body, so that the situation that the tension meter body easily slips out of a hand of a user can be avoided.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
