Description

Clip device

The present invention relates to the technical field of clasping appliances, in particular to a clasping device with hooks and loops.

In order to identify personnel and access control management, the company's line number will generally issue employee identification cards for identification. At the same time, for the convenience of hanging, it will be equipped with identification sleeves and fixed clip appliances, so that employees can wear clothes for identification purposes. .

As shown in Figures 1 and 2, the existing clamping device includes a first clamping arm A1, a second clamping arm A2, and an elastic member E arranged between the first clamping arm A1 and the second clamping arm A2. The elastic member E has two elastic pieces E1, respectively abutting the first clamping arm A1 and the second clamping arm A2, the elastic piece E1 of the elastic member E is deformed when installed between the first clamping arm A1 and the second clamping arm A2, so the two The two elastic pieces E1 respectively apply torques in opposite directions to the first clamping arm A1 and the second clamping arm A2, so that the first clamping arm A1 and the second clamping arm A2 rotate around the pivot axis, so that the first clamping arm A1 and the first clamping arm A1 and the second clamping arm A2 rotate around the pivot axis. The clamping parts of the two clamping arms A2 abut against each other to clamp an article, such as an identification card.

The hook and loop member 40 includes two hook portions 41 and a half-ring portion 42. The hook portions 41 are connected to the half-ring portion 42, and the ends of the two hook portions 41 are opposite to each other. Each hook 41 of the hook and loop member 40 has an extension arm 411 and an axis 412. The extension arm 411 is connected to the axis 412 to form an L shape, and the The extension arm 411 is connected to one end of the half-ring portion 42, and the end surface of the shaft 412 is opposite to the end surface of the shaft 412 of the other hook portion 41.

The first pivot portion 13 of the first clamp arm 10 is combined with the second pivot portion 23 of the second clamp arm 20. Since the distance between the first flanges 131 is smaller than the distance between the second flanges 231, the first flange 131 is disposed between the second flanges 231 and abuts against the second flanges 231 respectively. Each hook 41 penetrates the first axis hole 132 of the first pivoting portion 13, the second axis hole 232 of the second pivoting portion 23 and the torsion generating portion 31 of the elastic member 30 respectively. Furthermore, the shaft 412 penetrates through the first shaft hole 132 of the first pivoting portion 13, the second shaft hole 232 of the second pivoting portion 23 and the torsion generating portion 31. The end surfaces of the hooks 41 are aligned with each other to form a coaxial shaft S. The first clamping arm 10 and the second clamping arm 20 rotate around the shaft S as a center. As mentioned above, the elastic member 30 applies a torsion force to the first clamping arm 10 and the second clamping arm 20 respectively so that the first clamping portion 12 of the first clamping arm 10 abuts against the second clamping of the second clamping arm 20部22.

As shown in Figures 5 and 6, the extension arms 411 of the two hooks 41 are arranged in parallel, and the distance between the two extension arms 411 is greater than the width of the first clamping arm body 11 and the second clamping arm body 21. In addition, the diameter of the half-ring portion 42 is larger than the widths of the first clamping arm body 11 and the second clamping arm body 21. Therefore, the hook and loop member 40 can cross the first clamping arm body 11 and the second clamping arm body 21 to rotate with each other with the axis 412 as the axis.

As shown in Figures 7 and 8, since the hook and loop member 40 is pivotally connected to the pivotal connection of the first flange 131 and the second flange 231, when the connecting member R is connected to the hook and loop member 40 and the connecting member is When a force is applied to the hook and loop member 40 by pulling, the distance b between the point of application of the force and the clamping point of the first clamping portion 12 and the second clamping portion 22 is greater than that of the prior art from the first clamping arm Or the end of the second clamping arm applies a short distance, that is, the applied force is relative to the clamping position of the first clamping portion 12 and the second clamping portion 22 The force arm is short, so the force applied to the clamping device 100 is relatively small. Therefore, when a hard object is clamped, the first clamping portion 12 and the second clamping portion 22 are not easily pushed apart. In the case of clamping flexible articles, since the force application point is at the center, the force on both sides of the first clamping portion 12 and the second clamping portion 22 is even, and the moment of force is small, so the article is not easy Slide out from the first clamping portion 12 and the second clamping portion 22. As mentioned above, because the shackle member 40 can cross the first clamping arm body 11 and the second clamping arm body 21 with the axis 412 as the axis to rotate with each other. In addition, for a small force, the reaction force generated by the deformation of the hook and loop member 40 can be absorbed and offset, and the first clamping arm 10 and the second clamping arm 20 will not be affected. The moment arm that exerts force in any direction on the axis of the hook and loop member 40 and the first clamping arm 10 and the second clamping arm 20 to affect the clamping force is the shortest and the moment is the smallest, which improves the hanging and clamping functions.

Please refer to Figure 9, which shows another embodiment of the clip device of the present invention. The structure of this embodiment is partly the same as that of the embodiment in FIG. 3, so the same elements are given the same symbols and their descriptions are omitted.

The difference between this embodiment and the embodiment shown in Figure 3 is that this embodiment further includes a clamping sleeve 50, which is arranged between the clamping ends of the first clamping arm 10 and the second clamping arm 20, and the clamping sleeve 50 includes two oppositely arranged clamping sleeve portions 51 and a connecting portion 52 connecting the clamping sleeve portions 51. The clamping sleeve portions 51 are in a relatively protruding shape and abut against each other. The connecting portion 52 is adjacent to the axis 412 of the hook portions 41 of the hook and loop member 40 and the torsion generating portion 31 of the elastic member 30. The clamping sleeve 50 may be a soft element made of rubber. The article is composed of the elastic member 30. The first clamping arm 10 and the second clamping arm 20 are clamped between the inner edges of the two clamping sleeve portions 51 by applying force. The clamping sleeve portion 51 and the connecting portion 52 are integrally formed. When the connecting portion 52 of the clamping sleeve 50 is bent and the clamping sleeve 50 is placed between the first clamping arm 10 and the second clamping arm 20, the connecting portion 52 will be formed. The deformation generates stress and causes the clamping sleeve portion 51 to abut against the inner surfaces of the inner edges of the clamping ends of the first clamping arm 10 and the second clamping arm 20.

In the clamping device of the present invention, since the hook and loop member connected with the connecting piece is arranged at the pivotal joint of the first clamping arm and the second clamping arm, the connecting piece is pulled to exert force on the action point of the clamping device and the clamping The distance between the clamping point of the buckle device to clamp the article is shorter than the distance applied from the end of the first clamping arm or the second clamping arm in the prior art, so that the torque applied to the clamping device is smaller, and the article is thus clamped It is not easy to separate from the clamping device.

However, the above are only the preferred embodiments of the present invention, and should not be used to limit the scope of implementation of the present invention, that is, simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the description of the invention, All are still within the scope of the invention patent.
