Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a portable wrench. Background Art

[0002] A wrench is a commonly used tool, primarily used to tighten or remove nuts, bolts, and other fasteners. It comes in many types, including open-end wrenches, ring spanners, adjustable wrenches, and socket wrenches, each with its own specific purpose. During the maintenance of suction cups used by industrial robots, a wrench is required to remove multiple suction cups.

[0003] Current wrenches often have the following problems when dealing with suction cup removal:

[0004] 1. The traditional hardware wrench is too thick. The thickness of the wrench needs to be less than 8mm to quickly fit into the installation joint of the suction cup.

[0005] 2. The handle of the traditional wrench is too long. When removing the suction cup in the middle of the rectangular coordinate robot, it is necessary to remove other suction cups within the length of the handle before removing the suction cup in the middle;

[0006] 3. The suction cup installation joint model is external thread G3 / 8. After the wrench is clamped on the suction cup interface, it needs to be rotated 180° to return to the initial line. All suction cups within the fan-shaped area of ​​the wrench rotation need to be removed. Utility Model Content

[0007] The purpose of the utility model is to provide a portable wrench. The utility model has a C-shaped structure.

[0024] See also Figure 1-5 A portable wrench includes a bottom plate 1, a connecting plate 2 and a top plate 3. The bottom plate 1 and the connecting plate 2 are fixedly connected on the surface, the connecting plate 2 and the top plate 3 are fixedly connected on the surface, and a mounting port 4 is opened on the surface of the top plate 3. Two support rods 5 are fixed at the bottom of the bottom plate 1. A rotating shaft 6 is rotatably connected to the bottom of the bottom plate 1. A storage sleeve 7 is slidably connected to the surface of the rotating shaft 6. A first sleeve 8 is fixed to the bottom of the storage sleeve 7. A second sleeve 9 is slidably connected to the inner wall of the first sleeve 8. A movable rod 10 is slidably connected to the inner wall of the second sleeve 9. A connecting clip 11 is fixed to the surface of the first sleeve 8. A combination rod 12 is fixed to the inner wall of the connecting clip 11. A handle 13 is provided on one side of the combination rod 12.

[0025] The bottom plate 1, the connecting plate 2 and the top plate 3 form the wrench as a whole. Through the design of this C-shaped wrench, the wrench can be directly placed on the surface of the suction cup. The support rod 5 is used as a force application point. When the first sleeve 8 rotates, the first sleeve 8 can contact the support rod 5, so that the first sleeve 8 can drive the bottom plate 1 to rotate through the support rod 5, thereby enabling the wrench to drive the suction cup to rotate, thereby realizing the disassembly operation of the suction cup. When the first sleeve 8 is operated, the second sleeve 9 and the movable rod 10 can be pulled outward to increase the overall length of the first sleeve 8, the second sleeve 9 and the movable rod 10. At the same time, the handle 13 can also be installed on the surface of the movable rod 10. Through this design, the torque can be increased, so that the wrench can be more easily disassembled from the suction cup. When the wrench is not in use, the handle 13 can be installed on the surface of the combination rod 12, so that the overall space occupied by the wrench is reduced, which makes it easier to carry. When disassembling, when the rotation direction is blocked, the first sleeve 8 can be pulled downward first to make the storage sleeve 7 move downward on the surface of the rotating shaft 6, so that the first sleeve 8 will not contact the support rod 5 after rotation. At this time, the rotation direction of the first sleeve 8 can be adjusted as needed. After adjusting to the required rotation direction, the first sleeve 8 can be moved upward again to make the storage sleeve 7 move upward on the surface of the rotating shaft 6. At this time, the first sleeve 8 can be rotated normally to drive the base plate 1 to rotate through the support rod 5, so that the suction cup can continue to be disassembled at different angles.

[0026] Furthermore, the overall height of the connecting plate 2 is 48 mm, the thickness of the top plate 3, the connecting plate 2 and the bottom plate 1 is 7-8 mm, and the diameter of the mounting opening 4 is 1.9 cm;

[0027] Since the main body of the traditional suction cup is 47mm-48mm, the overall height of the connecting plate 2 can be adapted to the suction cup, and since the thickness of the top connection position of the suction cup is 8mm, the thickness of the bottom plate 1, the connecting plate 2 and the top plate 3 are designed so that the bottom plate 1 and the top plate 3 can be normally placed on the surface of the suction cup, and the design of the diameter of the mounting port 4 ensures that after the bottom plate 1, the connecting plate 2 and the top plate 3 are placed on the surface of the suction cup, the mounting port 4 can contact the top surface of the suction cup.

[0028] Furthermore, first sliding grooves 14 are provided on the upper and lower sides of the surfaces of the second sleeve 9 and the movable rod 10, and first limiting blocks 15 are fixed on the upper and lower sides of the inner walls of the first sleeve 8 and the second sleeve 9, and the first limiting blocks 15 are slidably connected to the inner walls of the first sliding grooves 14;

[0029] When the movable rod 10 moves on the inner wall of the second sleeve 9, the first limit block 15 on the surface of the second sleeve 9 will slide on the inner wall of the first slide groove 14 on the surface of the movable rod 10, and when the second sleeve 9 moves on the inner wall of the first sleeve 8, the first limit block 15 on the surface of the first sleeve 8 will be able to slide on the inner wall of the first slide groove 14 on the surface of the second sleeve 9. Through this design, it is ensured that the movable rod 10 cannot rotate inside the second sleeve 9, and the second sleeve 9 cannot rotate inside the first sleeve 8, so that the movable rod 10 and the handle 13 can be installed and disassembled.

[0030] Furthermore, two second chute grooves 16 are formed on the inner wall of the storage sleeve 7, and two second limit blocks 17 are fixed on the surface of the rotating shaft 6. The second limit blocks 17 are slidably connected to the inner walls of the second chute grooves 16;

[0031] The rotating shaft 6 can drive the second limit block 17 to slide inside the second slide groove 16. This design can prevent the rotating shaft 6 from detaching from the storage sleeve 7, and also ensure that the rotating shaft 6 can drive the storage sleeve 7 to rotate normally through the cooperation between the second limit block 17 and the second slide groove 16.

[0032] Furthermore, a knob 18 is threaded through the surface of the storage sleeve 7;

[0033] After the rotating shaft 6 is adjusted to a position inside the receiving sleeve 7 , the friction force on the rotating shaft 6 can be increased by rotating the knob 18 , so that the receiving sleeve 7 can obtain a limiting effect on the surface of the rotating shaft 6 .

[0034] Furthermore, the surfaces of the movable rod 10 and the combination rod 12 are provided with threads, and the surface of the handle 13 is provided with thread grooves for use with the movable rod 10 and the combination rod 12;

[0035] With this design, the handle 13 can be mounted on the surface of the movable rod 10 or the combination rod 12 in a rotatable manner, which makes it more convenient for the operator to use and can be assembled and disassembled without the help of tools.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
