The mounting end 77 is fixedly attached to the handle 70. The cable first mounting portion 79 has a mounting portion through hole 74. The mounting portion 71 may be integrally formed with the handle 70, i.e., the mounting portion 71 may be a portion of the handle 70.

It will be appreciated that the bracket arm and the handle may be integrally formed or may be separately formed and then connected together. When the two are integrally formed, the upper ends of the holder arms extend, for example, laterally to form a portion to be held by a user, i.e., a handle. Even more, in some cases, the arm does not extend laterally, and the uppermost portion of the arm for the user to hold is the handle.

The actuating member 50 is connected to the operating member 10 and is movably connected to the holder arm 40. In the mounted state of the extension bracket 100 to the vacuum chuck jig 160, the contact portion 53 of the actuating member 50 is located above the release button 63, and when the user operates the movable portion 20 of the operating member 10, the actuating member 50 moves relative to the bracket arm 40 in accordance with the movement of the operating member 10, thereby pressing the release button 63 to effect the clamping release. Specifically, in the mounted state of the extension bracket 100 to the vacuum chuck jig 160, the contact portion 53 of the actuating member 50 moves relative to the bracket arm 40 with the movement of the operating member 10 for pressing the release button 63.

It will be understood that reference herein to "moving" is to be taken in a broad sense as being positionally variable, e.g., it is to be understood as movement, including translation, rotation, and the like.

Specifically, the holder arm 40 includes a holder trailing arm 41 and a holder cross arm 42. The holder cross arm 42 is connected to the lower end of the holder trailing arm 41 such that the holder arm 40 is configured in an inverted T shape. In a preferred embodiment of the present invention, the holder arm 40 includes two holder trailing arms 41 and two holder cross arms 42. The upper ends of the two bracket trailing arms 41 are each connected to a handle 70.

The connecting portion 51 extends at least partially into the support hole 43 to enable the actuating member 50 to rotate relative to the bracket arm 40, i.e. the connecting portion 51 is rotatably connected to the bracket arm 40. The contact portion 53 is located at least partially below the connecting portion 51 for contacting the release button 63 from above in the mounted state of the extension bracket 100 to the vacuum chuck jig 160. In the preferred embodiment of the present invention, each of the two bracket trailing arms 41 includes one support hole 43, and the two support holes 43 are symmetrically disposed about the axis AL of the handle 70. Both ends of the connecting portion 51 extend into the two support holes 43, respectively.

As shown in fig. 2, the actuating member 50 includes a first surface 55 perpendicular to the axis of the support hole 43. The first surface 55 can also be understood as a side surface of the contact portion 53 of the actuating member 50. On the first surface 55, the contact portion 53 may have an L-shaped, C-shaped or S-shaped cross-sectional shape, i.e., the contact portion 53 extends downward from the connecting portion 51 of the actuating member 50 in an L-shaped, C-shaped or S-shaped curved manner for contacting the release button 63 from above in the mounted state of the extension bracket 100 to the vacuum chuck jig 160. In the preferred embodiment of the present invention shown in fig. 2, the contact portion 53 has an S-shaped cross-sectional shape on the first surface 55 perpendicular to the axis of the support hole 43.

In an embodiment of the invention, which is not shown, the holder arm 40 comprises a shaft projecting towards the inside of the holder arm 40, the connecting portion 51 comprising a shaft hole into which the shaft extends at least partially, so that the actuation part 50 is rotatable relative to the holder arm 40. In this embodiment, the first surface 55 of the actuation member 50 is perpendicular to the axis of the shaft.

The operation member 10 includes a movable portion 20 and a cable 30.

The movable portion 20 includes an operation end 23 and a connection end 28 opposite to the operation end 23. The connecting end 28 of the movable portion 20 is movably connected to the first end 76 of the mounting portion 71. For example, the connecting end 28 of the movable part 20 is pivotably connected to the first end 76 of the mounting part 71, such that the movable part 20 is connected to the mounting part 71 and is movable between a rest position and an operating position. At the same time, the movable part 20 is also movable between the rest position and the operating position with respect to the handle 70, and the movable part 20 is also movable between the rest position and the operating position with respect to the holder arm 40.

The cable 30 is connected to the movable portion 20, and at least a portion of the cable 30 moves with movement of the movable portion 20 relative to the mounting portion 71.

Specifically, the cable 30 includes an inner core 31 and an outer sheath 32, the outer sheath 32 surrounding the inner core 31 and being slidable relative to the inner core 31. As shown in fig. 2 and 6, the actuating member 50 includes a cable second mounting portion 59, the cable second mounting portion 59 includes the actuating member through hole 54, and the cable first mounting portion 79 has a mounting portion through hole 74. The inner core 31 extends through the actuating member through hole 54 and the mounting portion through hole 74, an upper end of the inner core 31 is connected to the connecting end 28 of the movable portion 20, and a lower end of the inner core 31 is connected to the bracket arm 40. In the preferred embodiment shown in fig. 2, the lower end of the inner core 31 is connected to a bracket crossbar 42. Specifically, the lower end of the inner core 31 is fixedly connected to the cable third mounting portion 48 of the bracket arm 40 below the actuating member 50. The cable third mounting portion 48 is lower than the cable second mounting portion 59, i.e. the cable third mounting portion 48 is located on the elongate support 100 lower than the cable second mounting portion 59. The outer sheath 32 is confined between the movable part 20 and the actuating member 50 and surrounds the inner core 31. Specifically, the outer jacket 32 is confined between the cable first mounting portion 79 and the cable second mounting portion 59 and surrounds the inner core 31.

It will be appreciated that reference herein to the end of the plunger is not to be taken to mean an end face in the strict sense but includes an end face of the plunger and a portion adjacent the end face, for example as can be seen from the embodiment of figure 2, the portion of the plunger 31 adjacent the lower end face being fixedly connected to the cable third mount 48 on the bracket arm 40, with a portion of the plunger 31 still extending beyond this mount 48.

In the preferred embodiment shown in FIG. 2, the upper end of the outer cover 32 is secured to the cable first mounting portion 79, e.g., to the outer periphery of the mounting portion through bore 74, and the lower end of the outer cover 32 is secured to the cable second mounting portion 59, e.g., to the outer periphery of the actuation member through bore 54. The connecting positions of the two ends of the inner core 31 and the two ends of the outer sheath 32 on the elongated bracket 100 are the connecting end 28, the first cable mounting portion 79, the second cable mounting portion 59 and the third cable mounting portion 48 in this order from the upper end of the inner core 31 along the extending direction of the inner core 31.

The length of the inner core 31 is greater than the length of the outer sheath 32. The length of the inner core 31 between the connection end 28 and the cable third mounting portion 48 is greater than the linear distance between the connection end 28 and the cable third mounting portion 48. The length of the cable 30 (including the inner core 31 and the outer jacket 32) between the cable first mounting portion 79 and the cable second mounting portion 59 is greater than the linear distance between the cable first mounting portion 79 and the cable second mounting portion 59. The length of the cable 30 (including the inner core 31 and the outer sheath 32) between the mounting portion through bore 74 and the actuation member through bore 54 is greater than the linear distance between the mounting portion through bore 74 and the actuation member through bore 54. As shown in fig. 1 and 2, the cable 30 is in a relaxed state in which it is bent between the cable first mounting portion 79 and the cable second mounting portion 59. Specifically, between the mounting portion through-hole 74 and the actuation member through-hole 54, the cable 30 is in a relaxed state of bending.

The lower end of the inner core 31 may be fixedly attached to the bracket arm 40 by various means such as welding, bonding, and the like. Specifically, as shown in fig. 5, in a preferred embodiment of the present invention, the lower end of the core 31 may be detachably connected to the bracket crossbar 42 of the bracket arm 40 by means of bolts 91. The bracket crossbar 42 has a bracket crossbar hole 44, and a bolt 91 passes through the bracket crossbar hole 44. The bolt 91 has a bolt through hole 93, and the core 31 passes through the bolt through hole 93. Tightening the nuts 92 clamps the core 31 between the bracket crossbar 42 and the nuts of the bolts 91. It will be appreciated that the upper end of the inner core 31 may also be connected to the connecting end 28 of the movable portion 20 in a variety of ways.

In a preferred embodiment of the present invention, the connecting end 28 of the movable portion 20 is pivotally connected to the first end 76 of the mounting portion 71, and a biasing member (not shown) is mounted within the movable portion 20. As shown in fig. 2, when the user grips the handle 70 to pinch the movable portion 20, i.e., when the operating end 23 of the movable portion 20 is pivoted toward the handle 70, the movable portion 20 will move to the operating position. When the user releases his hand, the movable portion 20 will move back to the rest position (i.e., the position of the movable portion 20 in fig. 2) under the action of the internal biasing member. The operating position of the movable portion 20 is closer to the handle 70 than the rest position.

In the operating position, the connecting end 28 of the movable portion 20 moves due to the movement of the movable portion 20, so that the inner core 31 connected to the connecting end 28 is pulled, the upper end of the inner core 31 moves relative to the mounting portion 71, the handle 70 and the bracket arm 40, i.e. the user's operation of moving the movable portion 20 to the operating position causes the upper end of the inner core 31 to receive a pulling force which tends to straighten the inner core 31 located between the cable first mounting portion 79 and the cable third mounting portion 48. Thus, the length of the inner core 31 between the cable first mounting portion 79 and the cable third mounting portion 48 in the operating position is less than the length of the inner core 31 between the cable first mounting portion 79 and the cable third mounting portion 48 in the rest position. While the outer sheath 32 is not stretchable in the axial direction of the cable, when the length of the inner core 31 between the cable first mounting portion 79 and the cable third mounting portion 48 becomes small, the lower end of the outer sheath 32 will move downward relative to the inner core 31 to ensure that the length of the inner core 31 between the cable first mounting portion 79 and the cable second mounting portion 59 is constant. Since the lower end of the outer sleeve 32 is fixed to the cable second mounting portion 59 at the actuating member through hole 54 of the actuating member 50, when the lower end of the outer sleeve 32 moves downward, a downward actuating force is applied to the actuating member 50 at the cable second mounting portion 59, so that the contact portion 53 of the actuating member 50 rotates downward with the connecting portion 51 of the actuating member 50 as the shaft, i.e., the contact portion 53 of the actuating member 50 moves downward relative to the holder arm 40 with the movement of the movable portion 20 of the operating member 10.

In the mounted state of the extension bracket 100 to the vacuum chuck jig 160, the contact portion 53 of the actuating member 50 contacts the release button 63 of the vacuum chuck jig 160 from above. When the user operates the movable portion 20, the force applied to the movable portion 20 by the user finally moves the contact portion 53 of the actuating member 50 downward, so that the contact portion 53 touches the release button 63 from above, and the negative pressure chamber of the vacuum chuck jig 160 is communicated with the external atmosphere, thereby achieving the clamping release.

The contact portion 53 touches the release button 63 from above once every time the user operates the movable portion 20, i.e., once every time the operating end 23 is pinched to pivot toward the knob 70. When the user continues to pinch the operating end 23 to pivot it toward the handle 70 and to keep the movable part 20 in the operating position, the contact part 53 continues to touch the release button 63 from above, so that the negative pressure chamber of the vacuum cup jig 160 is continuously communicated with the external atmosphere to quickly release the grip. The vacuum chuck clamp 160 has a biasing member capable of applying an upward biasing force to the release button 63, and when the user releases his hand to move the movable portion 20 back to the rest position, the downward actuating force applied by the outer sleeve 32 to the actuating member 50 is removed, resulting in a reduced pressure above the release button 63, and the release button 63 springs upward under the biasing force of the biasing member, isolating the negative pressure chamber of the vacuum chuck clamp 160 from communicating with the outside atmosphere.

In a preferred embodiment according to the present invention, the length of the inner core 31 between the connection end 28 and the cable third mounting portion 48, and the length of the cable 30 (including the inner core 31 and the outer jacket 32) between the cable first mounting portion 79 and the cable second mounting portion 59, can be determined through experimentation. The cable 30 may be a bowden cable.

It will be appreciated that other means of restraining the outer jacket 32 between the cable first and second mounting

portions

79 and 59 may be used in addition to the above-described method.

In the attached state of the extension bracket 100 to the vacuum chuck jig 160, when the movable part 20 is located at the operation position, the actuation member 50 presses the release button 63.

According to the present invention the extension bracket 100 comprises a first mounting member 45 for mounting the extension bracket 100 to a vacuum chuck clamp 160. As shown in fig. 2, the extension bracket 100 according to the present invention includes four first mounting members 45, and the four first mounting members 45 are located at the lower end of the extension bracket 100. Specifically, four first mounting members 45 are located on the bracket crossbar 42 of the extension bracket 100. As shown in fig. 2, the stand cross arm 42 includes a downwardly extending end 46 with four first mounting members 45 at the end 46. Preferably, the two bracket arms 40 and the four first mounting members 45 of the present invention are symmetrically disposed about a plane passing through the axis AL of the handle 70 and perpendicular to the pivot axis about which the movable portion 20 pivots relative to the mounting portion 71, such a symmetrical configuration making the extension bracket 100 easy to produce.

With the utility model discloses a vacuum chuck anchor clamps 160 that adds long support 100 and use can include at least one second installed part 65 for use with first installed part 45 cooperation, with will add long support 100 and install vacuum chuck anchor clamps 160. As shown in fig. 3, the vacuum chuck jig 160 includes four second mounts 65. Preferably, four second mounting elements 65 are symmetrically arranged to cooperate with four symmetrically arranged first mounting elements 45.

The first and second mounting

members

45, 65 may be a threaded connection, a snap connection, a hook connection, etc. that cooperate with one another. Specifically, as shown in fig. 3 and 4, in a preferred embodiment of the present invention, the first mounting member 45 is configured as a protrusion 45, and the protrusion 45 protrudes toward the outside of the extension bracket 100. The second mounting member 65 includes a mounting hole 66 that is capable of cooperating with the projection 45, the mounting hole 66 being a through hole. The projections 45 cooperate with the mounting holes 66 to connect the extension bracket 100 to the second mounting member 65.

Herein, the inner direction of the holder arm (or the extension holder) means a side of the holder arm facing the vacuum chuck jig 160 in an installation state where the extension holder 100 is installed to the vacuum chuck jig 160; the outer direction of the holder arm (or the extension holder) means a side of the holder arm facing away from the vacuum chuck jig 160 in an installation state where the extension holder 100 is installed to the vacuum chuck jig 160. As shown in fig. 2, according to the extension bracket 100 of the present invention, the inner sides of the two bracket trailing arms 41 of the bracket arm 40 are opposite to each other, and the inner sides of the two bracket cross arms 42 of the bracket arm 40 are opposite to each other.

As shown in fig. 2, in a preferred embodiment according to the present invention, since the support trailing arms 41 of the two extension supports 100 are made of a plate material, and the middle portions thereof are outwardly bent away from each other, so that when the respective upper ends of the two support trailing arms 41 are both connected to the handle 70, the distance between the lower ends of the two support trailing arms 41 is greater than the distance between the upper ends of the two support trailing arms 41. This structure causes the lower ends of the two holder arms 40 to tend outward, i.e., the lower ends of the two holder arms 40 tend to separate from each other. In a pre-mounted state where the extension bracket 100 is not mounted to the vacuum chuck jig 160, the distance between the lower ends of the two bracket arms 40 is L. The four second mounting members 65 of the vacuum chuck jig 160 are oppositely arranged two by two in the width direction D1 of the vacuum chuck jig, and the distance between the two opposite second mounting members 65 of the vacuum chuck jig 160 in the width direction D1 of the vacuum chuck jig is less than L (as shown in fig. 1 and 2). Thus, when the support arm 40 is positioned inside the second mounting member 65, the lower end of the support arm 40 will be urged outwardly against the inner side of the second mounting member 65, thereby allowing the elongate support 100 to be securely mounted to the vacuum chuck clamp 160.

It will be appreciated that the first mounting member 45 and the second mounting member 65 may be reversed. Specifically, the first mounting member may be configured as a through-hole and the second mounting member 65 may include a projection configured to project inwardly, the through-hole cooperating with the projection to connect the extension bracket 100 to the second mounting member 65. In this mounting manner, the distance between the two opposite second mounting members 65 of the vacuum chuck jig 160 in the width direction D1 of the vacuum chuck jig is still smaller than the distance L between the lower ends of the two holder arms 40 in the pre-mounted state in which the extension holder 100 is not mounted to the vacuum chuck jig 160, the holder arms 40 are still located inside the second mounting members 65, and the lower ends of the holder arms 40 are brought to abut against the inner side surfaces of the second mounting members 65, so that the extension holder 100 is firmly mounted to the vacuum chuck jig 160.

When the lengthened support 100 of the vacuum chuck clamp according to the present invention is used, the lower ends of the two support arms 40 (or the support cross arm 42) are held together relatively, i.e. the distance between the lower ends of the two support arms 40 is reduced. The four first mounting members 45 are then aligned with the four second mounting members 65 with the four projections 45 extending into the four mounting holes 66, thereby mounting the extension bracket 100 to the vacuum chuck jig 160 such that the contact portion 53 of the actuating member 50 contacts the release button 63 from above. At this point, the user does not operate the movable portion 20 of the elongate support 100, i.e., applies a downward actuating force to the actuating member 50, and the release button 63 isolates the negative pressure chamber of the vacuum chuck clamp 160 from communication with the outside atmosphere. The user then activates the vacuum chuck jig 160 to operate the suction device (e.g., suction pump) of the vacuum chuck jig 160. The user then holds the handle 70 and places the elongated support 100 along with the vacuum chuck clamp 160 on the surface of the item to be held. The vacuum chuck clamp 160 holds the object under the suction of the vacuum chuck clamp 160. At this point, the user may grasp the handle 70 and lift the elongate support 100 to the target position along with the vacuum cup gripper 160 and the gripped item. At the target position, the user operates the movable portion 20, i.e., the user grips the handle 70 to pinch the movable portion 20, pivots the operating end 23 of the movable portion 20 toward the handle 70, causes the contact portion 53 to touch the release button 63 from above by the relative movement of the outer sheath 32 and the inner core 31 of the cable 30, communicates the negative pressure chamber of the vacuum chuck jig 160 with the outside atmosphere, and effects the grip release.

It will be appreciated that the present application is not limited to the preferred embodiments disclosed above. In an embodiment not shown, for example, instead of having to make the outer sheath 32 and the inner core 31 of the cable 30 slide relative to each other (even if the outer sheath 32 is not needed and only the inner core 31 is needed), a member such as a fixed pulley member that can change the direction of force is provided on the support arm 40 (e.g., at a position lower than the actuating member 50 on the support arm 40), and the lower end of the cable 30 is connected to the lower side of the actuating member 50 after passing around the fixed pulley member (e.g., at a position corresponding to the cable second mounting portion 59 below the actuating member 50), and the actuating member 50 can rotate and/or translate downward relative to the support arm 40, so that when the movable portion 20 moves toward the handle 70, the inner core 31 is moved, and the contact portion 53 of the actuating member 50 is moved downward, and the function of pressing the release button 63 is realized.

In another embodiment, not shown, the connecting portion 51 of the actuating member 50 is widened such that the connecting portion 51 can extend on both the left and right sides of the axis of the supporting hole 43 shown in fig. 2 (in the embodiment shown in fig. 2, the connecting portion 51 extends only on the left side of the axis of the supporting hole 43), and the inner core 31 of the cable 30 is connected to the portion of the connecting portion 51 located on the right side of the axis of the supporting hole 43 from above the actuating member 50, so that when the movable portion 20 moves toward the handle 70, the inner core 31 is moved, and the actuating member 50 rotates about the axis of the supporting hole 43, causing the contact portion 53 of the actuating member 50 to move downward, achieving the function of pressing the release button 63.

In conclusion, when the initial position or the target position of article are lower (if press close to ground), according to the utility model discloses a vacuum chuck anchor clamps's the assistance of extension support down, the user need not bow and can contact article or press the release button with vacuum chuck anchor clamps, has reduced intensity of labour, has improved work efficiency simultaneously. It will be appreciated that the elongate support extends the physical dimensions of the vacuum chuck clamp so that a user can perform both a clamping and a release clamp at a relatively large distance, i.e. within the reach of the elongate support length, and not just the manipulation of items on the floor. Therefore, when the lengthened support is installed on the vacuum chuck clamp, a user can move, place and release the vacuum chuck clamp through operating the lengthened support, and user experience is improved. According to the utility model discloses an extension support of vacuum chuck anchor clamps provides appurtenance for user's operation vacuum chuck anchor clamps, has increased flexibility and the convenience of using vacuum chuck anchor clamps.
