Such that when cable 30 enters through actuation assembly through bore 54 from upper opening 54E, outer sheath 32 is blocked by step face 54C and inner core 31 can pass all the way out through lower opening 52F.

As shown in fig. 5, the clip 47 has a clip notch 47A. When the second cable attachment member 59 is attached such that the lower opening 52F of the actuator assembly through bore 54 is aligned with the clip notch 47A, the plunger 31 can continue to exit the clip notch 47A after exiting the lower opening 52F, and the plunger 31 can be attached to the third cable attachment member 49.

As shown in fig. 5, the inner core 31 is detachably fixed to the cable third mounting member 49 after it passes out of the cable second mounting member 59. The cable third mounting member 49 is provided on the mounting plate 81. Specifically, the cable third mounting member 49 is a bolt, and the bolt stud is provided with a bolt through hole extending in a direction perpendicular to the axial direction of the bolt, the bolt through hole being located immediately adjacent to the bolt cap. The mounting plate 81 has a fastening hole for passing the bolt 49. The lower end of the inner core 31 is inserted through the bolt through hole, the bolt 49 is inserted through the fastening hole, and the nut 92 is tightened to clamp the inner core 31 between the mounting plate 81 and the bolt cap. It will be appreciated that the lower end of the inner core 31 may be secured to the mounting plate 81 in other ways, such as by welding, gluing.

As shown in fig. 4, the upper end of the cable 30 is connected to the cable first mounting member 79. The cable first mounting member 79 has a mounting portion through hole 74 therein. Similar to the actuator assembly throughbore 54, the mounting throughbore 74 also includes a large bore portion which can receive the outer sheath 32 of the cable 30 and a small bore portion which can only receive the inner core 31 of the cable 30. Thus, the inner core 31 may extend through the entire mounting portion through hole 74. The upper end of the inner core 31 is connected and fixed to the connecting end 28 of the movable part 20 so that the inner core 31 can move together with the movable part 20.

Thus, the handle 70 or support arm assembly 40 of the extension support 100 includes the cable first mounting member 79, the actuation assembly 50 includes the cable second mounting member 59, and the support arm assembly 40 includes the cable third mounting member 49. The outer jacket of the cable 30 is confined between the cable first mounting member 79 and the cable second mounting member 59.

It will be appreciated that reference herein to the end of the inner core 31 is not to be taken to mean an end face portion in the strict sense but includes an end face portion of the inner core 31 and a portion adjacent the end face portion, for example as can be seen from the embodiment of figure 5, the portion of the inner core 31 adjacent the lower end face being fixedly connected to the cable third mounting means 49 on the bracket arm assembly 40, with a portion of the inner core 31 still extending beyond this mounting means 49.

In the elongated stent 100, 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 third cable mounting element 49 is greater than the linear distance between the connection end 28 and the third cable mounting element 49. The length of the cable 30 (including the inner core 31 and the outer jacket 32) between the cable first mounting member 79 and the cable second mounting member 59 is greater than the linear distance between the cable first mounting member 79 and the cable second mounting member 59. The length of the cable 30 (including the inner core 31 and the outer sheath 32) between the mounting portion throughbore 74 and the actuation assembly throughbore 54 is greater than the linear distance between the mounting portion throughbore 74 and the actuation assembly throughbore 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 member 79 and the cable second mounting member 59. Specifically, between the mounting portion through bore 74 and the actuation assembly through bore 54, the cable 30 is in a bent relaxed state.

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 and 4, when the user grips the handle 70 to pinch the movable portion 20, that is, 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 coupling end 28 of the movable part 20 moves due to the movement of the movable part 20, so that the inner core 31 coupled to the coupling end 28 is pulled, and the upper end of the inner core 31 moves relative to the mounting portion 71, the handle 70 and the bracket arm assembly 40, i.e. the user's operation of moving the movable part 20 to the operating position subjects the upper end of the inner core 31 to a pulling force that tends to straighten the inner core 31 located between the first and third

cable mounting elements

79, 49. Thus, the length of the inner core 31 between the cable first mounting member 79 and the cable third mounting member 49 in the operating position is less than the length of the inner core 31 between the cable first mounting member 79 and the cable third mounting member 49 in the rest position. While the outer sheath 32 is not telescopic in the direction of extension of the cable, as the length of the inner core 31 between the first 79 and third 49 cable mounting members becomes smaller, the lower end of the outer sheath 32 will move downwards relative to the inner core 31 to ensure that the length of the inner core 31 between the first 79 and second 59 cable mounting members is constant.

As shown in fig. 6, since the lower end of the outer sleeve 32 is constrained to the step surface 54C of the cable second mounting member 59, when the lower end of the outer sleeve 32 moves downward, a downward actuating force will be applied to the actuating assembly 50 (specifically, the cable second mounting member 59 of the connecting assembly 51 of the actuating assembly 50) at the step surface 54C, so that the contact member 53 of the actuating assembly 50 moves downward, i.e., the contact member 53 of the actuating assembly 50 moves downward relative to the support arm assembly 40 with the movement of the movable portion 20 of the operating assembly 10. In the mounted state of the extension bracket 100 to the vacuum chuck apparatus 160, the contact piece 53 of the actuator assembly 50 contacts the button 63 or 64 of the vacuum chuck apparatus 160 from above. When the user operates the movable portion 20, the force applied to the movable portion 20 by the user eventually moves the contact member 53 of the actuating assembly 50 downward, so that the contact member 53 presses the button 63 or 64 from above, and the suction is released or absorbed.

As shown in fig. 6, the spring 58 is fitted over the outer peripheral surface of the cable second mounting member 59 and is sandwiched between the flange 59A of the cable second mounting member 59 and the mounting plate 81. When the user operates the movable portion 20 to move the cable second mounting member 59 downward, the spring 58 is compressed by the pressure of the flange 59A. When the user releases his hand to move the movable part 20 back to the rest position, the downward force applied to the cable second mounting member 59 disappears, and the cable second mounting member 59 will rise back to the original position under the biasing force of the spring 58, so that the contact piece 53 also moves upward to be away from the push button 63 or 64.

The connection assembly 51 also includes a capture tab 55. As shown in fig. 6, the surface of the cable second mounting member 59 is further provided with a circumferentially extending groove 59B for mounting the catch piece 55. The outer diameter of the cable second mounting member 59 at the groove 59B is smaller than the inner diameter of the mounting plate through hole 82. In the axial direction of the cable second mounting member 59, the distance between the recess 59B and the flange 59A is greater than the sum of the height dimension of the collar 47 and the compression height of the spring 58. The position plate 55 has, for example, a notch structure that is arranged to match the groove 59B so that the position plate 55 can be mounted in the groove 59B. The outer edge of the capture tab 55 is sized larger than the inner diameter of the mounting plate through hole 82. When the cable second mounting member 59 is mounted, the spring 58 is compressed so that the groove 59B is positioned below the mounting plate 81, and then the card position piece 55 is mounted to the groove 59B. When the cable second mounting member 59 is moved upward by the biasing force of the spring 58, the catching piece 55 is caught at the mounting plate through-hole 82, so that the cable second mounting member 59 can be prevented from coming out of the mounting plate through-hole 82.

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 member 49, and the length of the cable 30 (including the inner core 31 and the outer sheath 32) between the cable first mounting member 79 and the cable second mounting member 59, can be determined experimentally. The cable 30 may be a bowden cable.

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

cable mounting members

79, 59 may be used in addition to the above-described methods. For example, the upper end of the outer cover 32 may be fixed to the first cable mounting member 79 by means of bonding or the like, and the lower end of the outer cover 32 may be fixed to the second cable mounting member 59 by means of bonding or the like. It will be appreciated that the operating assembly 10 may be movably provided to the handle 70 or to the holder arm assembly 40 in a manner similar to that described above. The cable first mounting member 79 may also be provided on the handle 70 or the bracket arm assembly 40. The cable third mounting part 49 may be provided directly at the first bracket arm 41.

In another embodiment, the manipulator of the elongate support 100 may take on another configuration, as shown in FIG. 14. The following focuses on differences between the embodiment shown in fig. 14 and the embodiment shown in fig. 2.

In the embodiment shown in fig. 14, the actuating assembly 150 includes a connecting assembly 151 and a contact portion 153 connected to the connecting assembly 151. The connection assembly 151 includes a cable second mounting member 159 and a connection plate 155. The first bracket arm 141 includes a support hole 183. Coupling plate 155 extends at least partially into support hole 183 to enable rotation of actuation assembly 150 relative to first bracket arm 141, i.e., actuation assembly 150 is movably coupled to first bracket arm 141. The contact 153 is located at least partially below the connection assembly 151. The cable second mounting member 159 is provided at the connection plate 155. The third cable mounting member 149 is disposed below the second cable mounting member 159 and on the first bracket arm 141. The first mount 145 is disposed at a lower portion of the first bracket arm 141. When the cable 130 passes through the cable second mounting member 159, only the inner core 131 can pass completely through the cable second mounting member 159 to the cable third mounting member 149. When the user operates the movable portion of the extension bracket of this embodiment, the cable second mounting member 159 moves downward, so that the link plate 155 rotates relative to the first bracket arm 141, and the contact portion 153 moves downward so that the button of the vacuum chuck device can be pressed. That is, the actuating assembly 150 is connected to the operating assembly and moves with the movement of the operating assembly relative to the bracket arm assembly so that at least one button of the vacuum chuck apparatus can be pressed in a mounted state of the extension bracket to the vacuum chuck apparatus.

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.

Preferably, the elongate support 100 includes two sets of operating means as described above, a first set for depressing the actuator button 64 of the vacuum cup means 160 and a second set for depressing the release button 63 of the vacuum cup means 160. When the initial position or the target position of the object is low (e.g., close to the ground), the user can operate the vacuum chuck device 160 by the operating device of the lengthened bracket 100 without bending down, thereby reducing the labor intensity and improving the working efficiency.

When the object to be suctioned by the vacuum chuck apparatus 160 is heavy, it is often desirable to have a plurality of people involved. To solve this problem, as shown in fig. 2, the arm assembly 40 of the extension bracket 100 includes two second bracket arms 42 respectively located at two sides of the first bracket arm 41, and each second bracket arm 42 is provided with a handle 70 (for example, each second bracket arm 42 is provided with two handles 70) for being held by a user, so that the extension bracket 100 can be used by multiple persons (for example, 2 persons).

Specifically, as shown in fig. 9, the first bracket arm 41 includes a cross bar 41A and a vertical bar 41B, a middle portion (point M) of the cross bar 41A is connected with an upper portion of the vertical bar 41B, and the second bracket arm 42 is pivotably connected to an end portion (point N) of the cross bar 41A. The operating assembly 10 of both sets of operating means may be provided to one or both of the two second carriage arms 42. For example, the two mounting portions 71 and the two movable portions 20 may be provided on the same second holder arm 42 at the same time, or may be provided on two holder arms 42.

The bracket arm assembly 40 also includes a slider 44 and a diagonal rib 43. The slider 44 is fitted over the first bracket arm 41 and is movable along the first bracket arm 41. The first end (point K) of the tilted rib 43 is pivotably coupled to the slider 44, and the second end (point J) thereof is pivotably connected to the second bracket arm 42. Since the bracket arm assembly 40 comprises two second bracket arms 42, it also comprises two tilted ribs 43, a first end of each tilted rib 43 being pivotably connected to the slider 44, and a second end of each tilted rib 43 being pivotably connected to the two second bracket arms 42, respectively. Preferably, the first bracket arm 41, the second bracket arm 42, the diagonal rib 43 and the slider 44 constitute a radially symmetrical structure.

The slider 44 is fixable in a plurality of different fixed positions (points L) relative to the first support arm 41 such that the second support arm 42 is correspondingly positioned in a plurality of different rotational positions relative to the first support arm 41, including a folded position (as shown in fig. 10), a partially open position (as shown in fig. 9), and a fully open position (as shown in fig. 2). Specifically, the extension bracket 100 also includes a fixed pin 94 (shown in FIG. 11). The first bracket arm 41 includes a plurality of fixing through holes 46, and the plurality of fixing through holes 46 are arranged from top to bottom along the extending direction of the first bracket arm 41. The slider 44 includes a slider through hole 44A. When the slider 44 is moved along the first bracket arm 41 such that the slider through-hole 44A is aligned with one of the plurality of fixing through-holes 46, the slider 44 is fixed with respect to the first bracket arm 41 by extending the fixing pin 94 through the slider through-hole 44A and the fixing through-hole 46. At this time, the five sides of the pentagonal JKLMN are fixed, so the angles of the five inner angles are also fixed, so that the included angle between the second bracket arm 42 and the first bracket arm 41 is fixed.

In the preferred embodiment, when the slider through hole 44A is aligned with the uppermost located fixing through hole 46, the second bracket arm 42 is located at a fully open position relative to the first bracket arm 41, where the angle between the second bracket arm 42 and the first bracket arm 41 is 90 degrees (specifically, the angle between the second bracket arm 42 and the vertical bar 41B of the first bracket arm 41 is 90 degrees). When the slider through hole 44A is aligned with the fixing through hole 46 located at the lowermost position, the second bracket arm 42 is located at the folding position relative to the first bracket arm 41, and the angle between the second bracket arm 42 and the first bracket arm 41 is 0 degree (specifically, the angle between the second bracket arm 42 and the vertical bar 41B of the first bracket arm 41 is 0 degree). When the slider through hole 44A is aligned with the centrally located fixing through hole 46, the second bracket arm 42 is located in a partially open position relative to the first bracket arm 41, where the angle between the second bracket arm 42 and the first bracket arm 41 is acute. The partially open position is between the folded position and the fully open position.

As shown in fig. 12, one end of a pin body 94C of the fixing pin 94 is provided with a pull ring 94A, and the other end of the pin body 94C is provided with an elastic flange 94B. In the case of using the fixing pin 94, one end of the fixing pin 94 to which the pull ring 94A is attached is grasped, and the end of the fixing pin 94 provided with the elastic flange 94B is inserted into the through hole. The surface of the elastic flange 94B is curved (e.g., spherical) and is pressed by the through hole to be contracted when it contacts the opening edge or inner wall of the through hole, and is ejected by the elastic biasing force when it passes completely through the through hole. The fixing pin 94 can be removed by pulling the pull ring 94A and applying a force in a direction away from the first bracket arm 41.

Preferably, the length of the fixing pin 94 matches the size of the slider 44, so that the length of the fixing pin 94 between the pull ring 94A and the elastic flange 94B is the width of the slider 44, so that when the fixing pin 94 is mounted to the extension bracket 100, the pull ring 94A and the elastic flange 94B catch the slider 44, and the structure of the extension bracket 100 is more stable.

The extension bracket 100 according to the present invention includes a first mounting member 45 for mounting the extension bracket 100 to a vacuum chuck apparatus 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 lower portions of the first bracket arms 41. As shown in fig. 13, the first mounting member 45 is configured to include a first through hole 45A. Specifically, the first mounting member 45 is configured to include two opposing, axially spaced first through holes 45A.

The vacuum cup assembly 160 used in conjunction with the extension bracket 100 of the present invention includes at least one second mounting member 65 for use in conjunction with the first mounting member 45 to mount the extension bracket 100 to the vacuum cup assembly 160. As shown in fig. 3, the vacuum chuck device 160 includes four second mounting members 65. The second mounting member 65 includes a second through hole 65A.

When the extension bracket 100 is mounted to the vacuum chuck apparatus 160, the extension bracket 100 is mounted to the vacuum chuck apparatus 160 by positioning the second through-hole 65A between the two opposing first through-holes 45A and extending through the two first through-holes 45A and the second through-hole 65A using a mounting pin 96 (the mounting pin 96 also having a pull ring and a resilient flange) similar in construction to the mounting pin 94, thereby securing the second through-hole 65A relative to the two first through-holes 45A.

It will be appreciated that 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. The first mounting member 45 and the second mounting member 65 may be reversed.

When the second bracket arm 42 is located at different rotation angles with respect to the first bracket arm 41, the handle 70 is located at a different distance from the lower end of the first bracket arm 41, that is, the handle 70 is located at a different distance from the vacuum chuck device 160. The user can adjust the distance between the handle 70 and the vacuum chuck device 160 according to the height dimension of the object to be sucked and the height of the position where the object is located, thereby making the carrying easier. For example, if the height of the object is large, i.e., the top surface of the object is higher from the ground, the slider 44 of the elongated bracket is aligned with the lower fixing through hole 46, so that the angle between the second bracket arm 42 and the first bracket arm 41 is smaller, and the distance between the handle 70 and the vacuum chuck device 160 is smaller. When the user holds the handle 70, the vacuum chuck device 160 is located at a higher distance from the ground to accommodate the height of the object, which provides a better user experience. Conversely, if the height dimension of the object is small, the slider 44 is aligned with the upper fixing through-hole 46. The positions of the plurality of fixing through holes 46 can be calculated according to specific needs.

When the vacuum chuck system 200 according to the present invention is stowed, the second support arm 42 is in a folded position relative to the first support arm 41, as shown in fig. 10, to save space. As shown in fig. 9 and 10, the second support arm 42 is provided with a recess 42A for receiving a protruding structure (e.g., the suction cup 68) of the vacuum cup device 160. In the mounted state of the extension bracket 100 to the vacuum chuck device 160, when the second bracket arm 42 is located at the folded position, the second bracket arm 42 is parallel to the first bracket arm 41, the lowermost end (the end provided with the handle 70) of the second bracket arm 42 extends beyond the vacuum chuck device 160, and the concave portion 42A of the second bracket arm 42 catches the chuck 68 of the vacuum chuck device 160.

When using the extension bracket 100 of the vacuum chuck apparatus according to the present invention, the extension bracket 100 is first mounted to the vacuum chuck apparatus 160 such that the contact members 53 of the actuating assemblies 50 of the two sets of operating devices are aligned with the actuating button 64 and the release button 63, respectively, from above. The user then adjusts the angle of the second bracket arm 42 relative to the first bracket arm 41. Two users respectively hold the handles of the two second support arms 42 to place the vacuum cup device 160 on the object. The user first operates the movable portion 20 of the first set of operating means to press the start button 64 of the vacuum chuck means 160 to operate the suction pump of the vacuum chuck means 160. The vacuum chuck device 160 is attracted to the surface of the object as the suction pump draws air from inside the chuck 68. Both users can now lift the elongated bracket 100 together and then lift the object to the target location. After placing the object at the target site, the user operates the movable portion 20 of the first set of operating means again to press the start button 64 again, so that the operation of the suction pump is stopped. The user then operates the movable portion 20 of the second set of operating means to depress the release button 63. At this point the vent valve opens and the air pressure within the suction cup 68 gradually rises back allowing the vacuum cup apparatus 160 to be removed from the surface of the object. The user continues to operate the movable portion 20 of the second set of operating means so that the vent valve continues to open, facilitating a rapid return of air pressure within the suction cup. The operation is repeated, and the second object can be conveyed.

In summary, when the initial position or the target position of the object is low (such as close to the ground), the lengthened bracket of the vacuum chuck device and the vacuum chuck system with the lengthened bracket of the vacuum chuck device according to the utility model enable a user to operate the vacuum chuck device through the lengthened bracket without bending down, thereby reducing the labor intensity and improving the working efficiency. Simultaneously, the user can be according to the height control handle of object and the distance of vacuum chuck device, has further promoted user experience. The lengthened support is foldable, and the storage space is saved. The lengthened bracket of the vacuum chuck device provides an auxiliary tool for a user to operate the vacuum chuck device, and increases the flexibility and convenience of using the vacuum chuck device.
