[0027] The grabbing tool provided in the embodiments of the present application can be used for grabbing an open box, facilitating the carrying operation of the box. The box can be a cuboid structure or a cube structure.

[0028] For the convenience of understanding and description, three directions are defined in this paper, which are the first direction x, the second direction y and the third direction z. The first direction x and the second direction y can be understood as two directions arranged at an angle in the horizontal plane, and the third direction z can be understood as a direction perpendicular to the horizontal plane. Taking a box to be grasped as a cuboid or a cube as an example, the first direction x is the length direction of the box, the second direction y is the width direction of the box, and the third direction z is the height direction of the box.

[0029] In this embodiment, the grasping tool includes a bracket 10, a support block 21 and an adjusting piece 30. The bracket 10 includes a first end 10a and a second end 10b opposite in the first direction x. The first end 10a of the bracket 10 is provided with at least one support block 21 and at least one adjusting piece 30. The second end 10b of the bracket 10 is provided with at least one support block 21 and at least one adjusting piece 30. The adjusting piece 30 can move relative to the bracket 10 along the first direction x, and the support block 21 can move relative to the bracket 10 along the second direction y. In other words, the adjusting piece 30 can be telescoped relative to the bracket 10 in the first direction x, and the support block 21 can be telescoped relative to the bracket 10 in the second direction y. The first direction x and the second direction y are arranged at an angle.

[0030] The grasping tool can be used to grasp an open box. The top end of the box is in the form of an opening, and the inner wall of the box has an annular stepped surface facing the bottom of the box near the top end opening. For example, the top end of the side wall of the box has an extension wall protruding into the interior of the box. The bottom wall surface of the extension wall can form the aforementioned annular stepped surface.

[0031] When the box is grasped by the grasping tool, the positions of the support block 21 and the adjusting piece 30 relative to the bracket 10 can be adjusted first, so that the support block 21 and the adjusting piece 30 are in a position not interfering with the box, to facilitate placing the grasping tool in the box. After the grasping tool is placed in the box, the position of the adjusting piece 30 on the bracket 10 is adjusted, so that the adjusting piece 30 is extended in the direction away from the bracket 10 along the first direction x. The end of the adjusting piece 30 away from the bracket 10 can abut against the side wall of the box in the first direction x. The position of the support block 21 on the bracket 10 is adjusted, so that the support block 21 is extended in the direction away from the bracket 10 along the second direction y. The support block 21 supports the annular stepped surface in the third direction z. In this way, at least two adjusting pieces 30 at both ends of the bracket 10 abut against the two opposite side walls of the box in the first direction x, and the support block 21 supports the annular stepped surface of the box in the third direction z, thereby achieving grasping of the box. Further, the grasping tool and the box grasped by the grasping tool can be transported by a lifting device or other transfer equipment.

[0032] The support block 21 can be mounted on the support frame 10 through a mounting structure. For the convenience of description, the support block 21 and the related structure for mounting the support block 21 to the support frame 10 are collectively referred to as a displacement assembly 20.

[0033] In the embodiment, the displacement assembly 20 includes the support block 21, and further includes a fixing seat 22 and a screw member 23. The fixing seat 22 is fixedly connected with the support frame 10. The screw member 23 is limitingly connected with the fixing seat 22 in the second direction y, and is rotatably connected with the fixing seat 22. The support block 21 is threadedly connected with the screw member 23. The extension direction of the screw member 23 is consistent with the second direction y, that is, the screw member 23 extends along the second direction y. The limitingly connected screw member 23 with the fixing seat 22 in the second direction y means that the screw member 23 cannot move relative to the fixing seat 22 in the second direction y. The limitingly connected screw member 23 with the fixing seat 22 in the second direction y does not affect the rotation of the screw member 23.

[0034] In this way, the movement of the support block 21 in the second direction y can be realized by rotating the screw member 23. Specifically, when the screw member 23 is rotated, the screw member 23 cannot move along the second direction y because the position of the screw member 23 in the second direction y is limited. Under the thread cooperation between the support block 21 and the screw member 23, the rotation of the screw member 23 can be converted into the linear movement of the support block 21.

[0035] In application, the support block 21 is used to cooperate with the box to be grabbed to support the box to be grabbed in the height direction (i.e., the third direction z). Therefore, the support block 21 is arranged away from the support frame 10 compared with the fixing seat 22, in other words, the support block 21 is located on the outer side of the fixing seat 22 away from the support frame 10.

[0036] Here, the "outer" refers to the side away from the support frame 10, and correspondingly, the "inner" refers to the side close to the support frame 10. The "outer" and "inner" referred to below are understood in the same way and will not be repeated. The use of the "outer" and "inner" is only for the convenience of description or understanding of the technical solutions, and does not constitute a limitation on the protection scope.

[0037] The screw member 23 can include a threaded segment threadedly cooperating with the support block 21 and a connecting segment cooperating with the fixing seat 22. The connecting segment of the screw member 23 is rotatably inserted into the fixing seat 22. In specific implementation, a bearing can be arranged between the fixing seat 22 and the screw member 23 to stably support the screw member 23 and prevent the screw member 23 from rotating and causing abrasion to the fixing seat 22.

[0038] In some embodiments, the displacement assembly 20 can further include an elastic member 24. The elastic member 24 is located between the fixing seat 22 and the support block 21. One end of the elastic member 24 abuts against the fixing seat 22, and the other end of the elastic member 24 abuts against the support block 21.

[0039] After the above setting, in the application, by rotating the screw rod 23 to adjust the relative position of the support block 21 and the box, the elastic element 24 can be used to keep the support block 21 in the position of supporting the annular stepped surface, ensuring the reliable support of the box, which is beneficial to guarantee the safety and reliability of grabbing and carrying the box.

[0040] For example, the elastic element 24 can be a compression spring.

[0041] In a specific implementation, the elastic element 24 can be sleeved on the outer periphery of the screw rod 23.

[0042] In some embodiments, the displacement assembly 20 can further include a guide rod 25, the guide rod 25 is fixedly connected with the fixed seat 22, the support block 21 is sleeved on the guide rod 25, and the extension direction of the guide rod 25 is consistent with the second direction y, that is, the guide rod 25 extends along the second direction y.

[0043] After the above setting, the movement of the support block 21 relative to the support 10 can be guided by the guide rod 25 to ensure the directionality of the movement of the support block 21, and to ensure that the support block 21 can reliably support the box.

[0044] For example, the guide rod 25 can be provided with one, two or three, etc.

[0045] In some embodiments, the displacement assembly 20 can further include a hand wheel 26, the hand wheel 26 is fixedly connected to one end of the screw rod 23, and the hand wheel 26 is located on the side of the support block 21 away from the fixed seat 22. In other words, the hand wheel 26 and the fixed seat 22 are located on both sides of the support block 21 in the second direction y.

[0046] After the above setting, the user can conveniently rotate the screw rod 23 by operating the hand wheel 26, so as to realize the position adjustment of the support block 21 in the second direction y.

[0047] In some embodiments, the hand wheel 26 and the screw rod 23 can be provided as an integral structure to simplify the assembly process of the grabbing tool; in other embodiments, the hand wheel 26 and the screw rod 23 can be two relatively independent structural members, which can be fixedly connected by riveting, welding or fasteners.

[0048] In the present embodiment, the outer side of the support block 21 away from the support 10 has a groove structure 211, the opening of the groove structure 211 faces away from the support 10, and one groove side wall of the groove structure 211 forms a support surface 2111 for supporting the to-be-grabbed member (for example, the box).

[0049] The groove structure 211 comprises two opposite groove sidewalls arranged in the third direction z, and a groove bottom wall 2112. It can be understood that, in order to support the annular stepped surface of the box, the lower groove sidewall of the groove structure 211 is a support surface 2111.

[0050] In the application, the groove depth of the groove structure 211 can be set such that, when the support block 21 supports the annular stepped surface of the box, the groove bottom wall 2112 of the groove structure 211 abuts against the structure forming the annular stepped surface (such as the extension wall mentioned above) to constrain the box to be gripped in the second direction y.

[0051] In a specific implementation, the groove structure 211 of the support block 21 is located below the fixing seat 22, the screw rod 23, and the hand wheel 26 in the third direction z. In the application, the area where the groove structure 211 of the support block 21 is located is inside the box, which facilitates cooperation with the annular stepped surface of the box to be gripped. The hand wheel 26 can be located outside the box to facilitate the user to operate the hand wheel 26.

[0052] In the embodiment, the adjusting member 30 is arranged in the support block 21, and the adjusting member 30 is threadedly connected with the support block 21, that is, the adjusting member 30 is installed on the support frame 10 through the support block 21. In this way, the movement of the adjusting member 30 in the first direction x can be realized by rotating the adjusting member 30, so as to realize the abutment of the adjusting member 30 with the inner side wall of the box to be gripped. At the same time, the connection of the adjusting member 30 with the support block 21 can avoid the additional installation structure of the adjusting member 30, which is conducive to the structural simplification of the gripping tool.

[0053] The adjusting member 30 is arranged in the support block 21, and the adjusting member 30 comprises an inner end side close to the support frame 10 and an outer end side away from the support frame 10. In the application, the outer end side of the adjusting member 30 abuts against the inner side wall of the box to be gripped.

[0054] For example, the adjusting member 30 can be a bolt.

[0055] In actual application, the head of the bolt can be located at the inner end of the support block 21 close to the support frame 10 in the first direction x. In this way, after the gripping tool is arranged in the box to be gripped, the head of the bolt can be conveniently operated to rotate the bolt, so as to realize the abutment of the rod of the bolt with the inner side wall of the box.

[0056] In the illustrated embodiment, the gripping fixture can be used to grip a cuboid or cube-shaped box. The second direction y is perpendicular to the first direction x, meaning the moving direction of the adjusting member 30 is perpendicular to the moving direction of the support block 21. In application, the gripping fixture can constrain the box in the first direction x and the second direction y through the adjusting member 30 and the support block 21, while simultaneously supporting the box in the third direction z using the support block 21. Thus, the box can be moved by lifting and gripping the fixture.

[0057] The bracket 10 has support blocks 21 and adjusting components 30 installed on both sides of its first end 10a, and support blocks 21 and adjusting components 30 installed on both sides of its second end 10b. Thus, the bracket 10 has four sets of support blocks 21 and adjusting components 30 installed, which can support and hold the four corners of the box during application, improving the safety and reliability of the box gripping.

[0058] The groove structures 211 of the two support blocks 21 installed at the first end 10a of the bracket 10 are arranged back-to-back to ensure that the two support blocks 21 can support the annular stepped surfaces at the two opposite walls of the box. Similarly, the groove structures 211 of the two support blocks 21 installed at the second end 10b of the bracket 10 are arranged back-to-back.

[0059] The heads of the two adjusting members 30 located on the same side of the second direction y in the first end 10a and the second end 10b of the bracket 10 are arranged facing each other, so that the position of the adjusting member 30 can be adjusted by operating the head.

[0060] In this embodiment, a number of lifting lugs 40 are fixedly connected to the support 10. This allows hoisting equipment and other transfer equipment to conveniently lift and grab the gripping fixture and the box gripped by the gripping fixture through the lifting lugs 40.

[0061] In the illustrated example, four lifting lugs 40 are provided, located at the four corners of the support 10. This helps to ensure the stability and reliability of the lifting operation.

[0062] like Figure 3 As shown, in some embodiments, the support 10 includes a frame body 11, which is generally rectangular or square in shape, and four sets of support blocks 21 and adjusting members 30 are installed at the four corners of the frame body 11.

[0063] The bracket 10 may also include two connecting plates 12, which are fixedly connected to the opposite side walls of the frame body 11 in the first direction x. The two ends of the connecting plates 12 in the second direction y can extend out of the frame body 11. The support block 21 and the adjusting member 30 are specifically installed at the ends of the connecting plates 12 to facilitate cooperation with the box.

[0064] In specific implementation, the end of the connecting plate 12 can be provided with a plurality of first mounting holes 121, and the fixing seat 22 of the displacement assembly 20 can be fixedly connected with the first mounting holes 121 of the connecting plate 12 through bolts, screws or other fasteners. In other implementation, the fixing seat 22 and the connecting plate 12 can also be fixedly connected through welding or other fixing methods.

[0065] In specific implementation, the connecting plate 12 is further provided with second mounting holes 122, and the lifting lug 40 can be fixedly connected with the second mounting holes 122 of the connecting plate 12 through fasteners. The lifting lug 40 can also be fixedly connected with the connecting plate 12 through welding or other methods.

[0066] In other implementation, the lifting lug 40 can also be fixedly connected with the rack body 11.

[0067] In specific implementation, the rack body 11 can be further provided with a plurality of lightening holes 111, and the shape and number of the lightening holes 111 can be determined according to requirements. For example, the lightening holes 111 can be square, circular, elliptical or irregular.

[0068] The principles and implementation modes of the present application are described by using specific examples in the present application, and the above examples are only used to help understand the method and core idea of the present application. It should be noted that, for those skilled in the art, without departing from the principles of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
