FIGS. 2A to 7A and FIGS. 2B to 7B are schematic perspective views of the operation of the clamping device 100 of FIG. 1A, wherein the angle of view depicted in FIGS. 2A to 7A is the same as the angle of view of FIG. 1A, The viewing angles depicted in FIGS. 2B to 7B are the same as those in FIG. 1B. In order not to make the drawings too complicated, FIGS. 2A to 7A and 2B to 7B omit the drawing of the board body and the circuit board.

Please see Figures 2A and 2B first. The clamping device 100 shown in Figures 2A and 2B shows the clamping state (ie, the state of the clamping device as shown in Figures 1A and 1B ).

The casing 110 of the clamping device 100 includes an upper shell 112 and a side shell 114 connected to each other, and the upper shell 112 and the side shell 114 may substantially exhibit an orthogonal relationship. A portion of the side shell 114 is raised in a first direction to form a raised portion 116, wherein the first direction may be a normal direction of the surface of the unraised side shell 114, and the formed raised portion 116 may define a receiving space.

The clamping device 100 further includes limiting members 140A and 140B, elastic members 144 and fixing members 146A and 146B. The pressing member 120 can be connected to the protruding portion 116 of the side shell 114 through the limiting members 140A and 140B. Specifically, the pressing member 120 may have openings 121A and 121B, and the limiting members 140A and 140B may be assembled from rods and spacers, wherein the rod passes through the openings 121A and 121B of the pressing member 120 and is fixed to the side The bulge 116 of the shell 114 is assembled on the rod and is located on the same side of the bulge 116 and the pressing member 120 so that the pressing member 120 is positioned between the shim and the bulging portion 116.

With this configuration, the pressing member 120 is movable relative to the housing 110. In addition, the limiting members 140A and 140B limit the pressing member 120 to limit the moving range of the pressing member 120. For example, as shown in FIG. 1B, when the lower edge of the opening 121A of the pressing member 120 abuts against the lower edge of the limiting member 140A, it can be considered that the pressing member 120 has reached the uppermost end of its movable range, and when pressed When the upper edge of the opening 121A of the member 120 abuts the upper edge of the limiting member 140A, it can be considered that the pressing member 120 has reached the lowermost end of its movable range.

The pressing member 120 includes a pair of stop portions 122A and 122B and a pressing portion 124, wherein the stop portions 122A and 122B are located behind the side shell 114, and the vertical projection of the stop portions 122A and 122B on the side shell 114 falls on the ridge In the portion 116, taking FIG. 1B as an example, the vertical projections of the stoppers 122A and 122B of the pressing member 120 on the side shell 114 completely fall within the raised portion 116. With this configuration, when looking at the clamping device 100 from the perspective as shown in FIG. 1A, since the stop portions 122A and 122B of the pressing member 120 will be covered by the bulging portion 116, the user will not see the stop Parts 122A and 122B. In addition, the stop portions 122A and 122B of the pressing member 120 may be a pair of branches extending away from each other, that is, the pressing member 120 may have an inverted T shape. On the other hand, the pressing portion 124 of the pressing member 120 is located above the upper shell 112, that is, the pressing member 120 extends from the accommodating space defined by the raised portion 116 above the upper shell 112 to form the pressing portion 124, and The pressing portion 124 may extend along the extending direction of the upper shell 112 to facilitate the user's pressing operation.

In addition, the raised portion 116 and the pressing member 120 may have tongues 117 and 126 respectively, and the two ends of the elastic member 144 are sleeved on the tongues 117 and 126 respectively, wherein the elastic member 144 may be a spring and the elastic member The length of 144 can be configured to be different from its original length. With this configuration, the pressing member 120 can be pushed upward by the restoring force of the elastic member 144.

The pressing member 120 is located between the clamping members 130A and 130B, and the clamping members 130A and 130B include connecting portions 132A and 132B, clamping portions 134A and 134B, engaging portions 136A and 136B, first extending portions 138A and 138B, and The second extending portions 139A and 139B, wherein the connecting portions 132A and 132B of the clamping pieces 130A and 130B can be connected to the side shell 114 through the fixing pieces 146A and 146B. Specifically, the connecting parts 132A and 132B of the clamping members 130A and 130B will be located in front of the side shell 114, and the fixing members 146A and 146B will be fixed on the side shell 114 and pass through the connecting parts 132A and 132B, in which The fixing pieces 146A and 146B of the connecting portions 132A and 132B may be cylindrical. With this configuration, the clamping members 130A and 130B are rotatable relative to the housing 110, and the positions of the fixing members 146A and 146B can be regarded as the axial positions of the clamping members 130A and 130B when rotating.

The clamping parts 134A and 134B of the clamping members 130A and 130B are located above the upper shell 112 and include a clamping surface, wherein the clamping surface faces the upper shell 112 and is separated from the upper shell 112 by a gap, and the gap is used to The object clamped by the clamping device 100 is placed. For example, the plate body 210 depicted in FIGS. 1A and 1B is sandwiched between the clamping surface and the upper shell 112, and the plate body 210 overlaps the gap.

The engaging portions 136A and 136B of the clamping members 130A and 130B are located behind the side shell 114, that is, the engaging portions 136A and 136B of the clamping members 130A and 130B and the stop portions 122A and 122B of the pressing member 120 are located on the side The same side of the shell 114, and the vertical projections of the engaging portions 136A and 136B on the side shell 114 fall within the bulging portion 116. Taking FIG. 2B as an example, the engaging portions 136A and 136B of the clips 130A and 130B are on the side The vertical projection of the housing 114 falls completely within the raised portion 116. In this configuration, when the user looks at the clamping device 100 from the perspective as shown in FIG. 2A, due to the engaging portions 136A of the clamping pieces 130A and 130B The 136B and the 136B are shielded by the raised portion 116, so the engaging portions 136A and 136B located on the rear side of the raised portion 116 cannot be seen.

The second extending parts 139A and 139B of the clamping members 130A and 130B extend from the connecting parts 132A and 132B along a linear trajectory and are connected to the clamping parts 134A and 134B, and the first extending parts 138A and 130B of the clamping members 130A and 130B 138B extends from the clamping portions 134A and 134B and the second extending portions 139A and 139B along the curved path, and enters the accommodating space defined by the bulging portion 116 and extends to the engaging portions 136A and 136B.

Please return to FIGS. 1A and 1B again. When the plate body 210 is clamped by the clamping device 100, the positions of the stop portions 122A and 122B of the pressing member 120 and the engaging portions 136A of the clamping members 130A and 130B The movement paths of 136B and 136B respectively overlap, thereby restricting the movement of the engaging portions 136A and 136B of the clips 130A and 130B. That is to say, through the stop portions 122A and 122B of the pressing member 120, in the case depicted in FIGS. 2A and 2B, the clamping member 130A cannot rotate clockwise, and the clamping member 130B cannot Rotate counterclockwise to maintain the clamping relationship between the clamping device 100 and the plate 210.

Please see FIG. 3A and FIG. 3B. FIG. 3A and FIG. 3B are schematic diagrams after the pressing member 120 is pressed. When the pressing member 120 is pressed, and the upper edge of the opening 121A of the pressing member 120 abuts the upper edge of the limiting member 140A, the pressing member 120 can reach the lowermost end of its movable range. At this time, the positions of the stop portions 122A and 122B of the pressing member 120 will be separated from the movement path of the engaging portions 136A and 136B of the clamping members 130A and 130B, that is, the positions of the stop portions 122A and 122B and the engaging portions 136A and The movement paths of 136B will be separated from each other.

In the case where the positions of the stop portions 122A and 122B and the movement paths of the engaging portions 136A and 136B are separated from each other, the clamping pieces 130A and 130B can be rotated by external force. For example, the clamping device 100 may further include torsion springs 148A and 148B, wherein the torsion springs 148A and 148B can be sleeved on the fixing pieces 146A and 146B and fixed on the side shell 114, respectively, and connected to the connecting portions 132A and 132B. In the configuration depicted in FIGS. 3A and 3B, the torsion springs 148A and 148B are in a deformed state, and thereby provide a restoring force to rotate the clamping members 130A and 130B clockwise and counterclockwise, respectively. Although the number of torsion springs depicted in this embodiment is a pair, the disclosure is not limited to this. In other embodiments, more than two torsion springs may be provided to make the clamping member clockwise or Turn counterclockwise. On the other hand, the upper shell 112 of the housing 110 may have a notch 115, and when the pressing member 120 reaches the lowermost end of its movable range, the pressing portion 124 of the pressing member 120 may be located in the notch 115, thereby preventing the upper part The case 112 and the pressing portion 124 interfere with each other.

Please see FIGS. 4A and 4B. FIGS. 4A and 4B show schematic views of the clamping members 130A and 130B after rotation. After the clamping members 130A and 130B are rotated, the gap between the clamping members 130A and 130B and the upper shell 112 will also be correspondingly increased, so as to release the clamping device 100 to the board body (such as the board in FIGS. 1A and 1B) Body 210). In addition, the clips 130A and 130B may further include protruding portions 133A and 133B, wherein the protruding portions 133A and 133B protrude from the connecting portions 132A and 132B and are located in front of the side shell 114, and the side shell 114 may have a pair of limit positions Parts 113A and 113B, and the positions of the limiting parts 113A and 113B overlap with the moving paths of the protruding parts 133A and 133B, respectively. With this configuration, the rotation range of the clamping members 130A and 130B can be restricted. Taking FIG. 4A as an example, the clips 130A and 130B can rotate until the protruding portions 133A and 133B abut against the limiting portions 113A and 113B, and when the protruding portions 133A and 133B abut against the limiting portions 113A and 113B Next, the engaging portions 136A and 136B of the clamping members 130A and 130B are still located in the accommodating space defined by the raised portion 116.

Please see FIGS. 5A and 5B. FIGS. 5A and 5B are schematic diagrams showing the removal of the external force applied to the pressing member 120. After removing the external force applied to the pressing member 120, the pressing member 120 can be pushed upward by the restoring force of the elastic member 144, so that the pressing member 120 returns to the uppermost end of its movable range, and the pressing member 120 stops The positions of the parts 122A and 122B and the movement paths of the engaging parts 136A and 136B of the clips 130A and 130B will also overlap again.

Please see Figures 6A and 6B. Figures 6A and 6B show schematic diagrams of pressing the clips 130A and 130B. When the clamping device 100 is used to clamp the plate body again (for example, the plate body 210 in FIGS. 1A and 1B), the clamping portions 134A and 134B of the clamping members 130A and 130B can be pressed to rotate the clamping member 130A and 130B, and the gap between the clamping members 130A and 130B and the upper shell 112 is correspondingly reduced. Since the movement paths of the engaging parts 136A and 136B of the clamping members 130A and 130B and the positions of the stop parts 122A and 122B of the pressing member 120 respectively overlap, the engaging parts 136A and 136B follow the clamping members 130A and 130B Rotates to abut against the stop portions 122A and 122B of the pressing member 120. Then, since the pressing member 120 is movable, the pressing member 120 can be pushed downward when the engaging portions 136A and 136B abut against the stop portions 122A and 122B and apply thrust to the stop portions 122A and 122B .

When the pressing member 120 continues to be pushed downward until the positions of the stop portions 122A and 122B are separated from the movement paths of the engaging portions 136A and 136B, the engaging portions 136A and 136B can cross the stop portions 122A and 122B, and Continue to rotate, as shown in FIGS. 7A and 7B, wherein FIGS. 7A and 7B show schematic views of the engaging portions 136A and 136B crossing the stop portions 122A and 122B. After the engaging portions 136A and 136B cross the stop portions 122A and 122B, continuous rotation of the clamping members 130A and 130B will cause the clamping device 100 to assume the state shown in FIGS. 2A and 2B to be restricted by the pressing member 120 The movement of the clamping members 130A and 130B.

During the operations depicted in FIGS. 2A and 2B to 7A to 7B, the positions where the pressing member 120 and the clamping members 130A and 130B are in contact are all behind the side shell 114, and they occur The vertical projection of the contact portion located on the side shell 114 will fall completely within the ridge 116. That is to say, these contact portions can be shielded by the ridge 116. Therefore, even if the pressing member 120 and the clamping members 130A and 130B are in contact with each other and cause abrasion (such as scratches or paint drop), these abraded parts are covered by the ridges 116 and will not be seen by the user. In order to provide users with a good experience.

In summary, the clamping device includes a housing, a pressing member, and a clamping member, wherein the pressing member has movability, and the clamping member has rotatability. By rotating the clamping member, an external object (such as a plate) can be clamped between the casing and the clamping member. The pressing member can be moved to different positions, where when the pressing member is in the first position (as depicted in FIGS. 2A and 2B), the position of the stopper of the pressing member will match the position of the engaging portion of the clamping member The movement paths overlap, thereby restricting the movement of the clamping member to maintain the clamping relationship of the clamping device to the external object, wherein when the pressing member is in the second position (as shown in FIGS. 3A and 3B), pressing The position of the stop part of the piece will be separated from the moving path of the clamping part of the clamping piece, so that the clamping piece can be rotated by the torsion spring, and then the clamping relationship of the clamping device to the external object is released. During the period when the pressing member is moved to different positions, the parts where the pressing member and the clamping member come into contact can be shielded by the ridges. Therefore, even if there is wear on these contacting parts, the user does not see these parts. Worn parts.

Although this disclosure has been disclosed in various ways as above, it is not intended to limit this disclosure. Anyone who is familiar with this skill can make various changes and retouching without departing from the spirit and scope of this disclosure.
