[0044] The following is a preferred embodiment of a detachable pull structure 1 and a pull head provided by this utility model, which can solve the above technical problems.
[0045] A preferred embodiment of this utility model provides a zipper puller. Please refer to... Figures 1-6The zipper pull includes a base 2 and a detachable pulling structure 1. The detachable pulling structure 1 includes a base plate 11, a connecting piece 12, a limiting member 13, and a handle 14. The base plate 11 is connected to the base 2, and the base plate 11 is provided with a first through hole 111 and a first clearance hole 112. The first through hole 111 penetrates the base plate 11 along its thickness direction. The first clearance hole 112 is located on one side of the periphery of the first through hole 111 and communicates with the first through hole 111.
[0046] The connecting piece 12 is stacked on top of the substrate 11. The connecting piece 12 is provided with a second through hole 121 and a second clearance hole 122. The second through hole 121 penetrates the connecting piece 12 along its thickness direction and is coaxially arranged with the first through hole 111. The second clearance hole 122 is located on one side of the periphery of the second through hole 121 and communicates with the second through hole 121. The second clearance hole 122 can communicate with the first clearance hole 112.
[0047] The limiting member 13 includes a limiting piece 131 and a connecting post 132. The limiting piece 131 is located on the side of the connecting piece 12 opposite to the base plate 11. One end of the connecting post 132 is connected to one side of the limiting piece 131 in the thickness direction, and a protrusion 1321 is provided on the periphery of the other end. The connecting post 132 can be rotatably inserted through the first through hole 111 and the second through hole 121, and the protrusion 1321 can be inserted through the first clearance hole 112 and the second clearance hole 122, and abut against the side of the base plate 11 opposite to the connecting piece 12.
[0048] The handle 14 is connected to the connecting piece 12. The handle 14 can be a rope, plastic strip, or other structure that can pull the connecting piece 12.
[0049] The detachable pull structure 1 and pull head of this utility model allow for the following steps when disassembling the handle 14: align the first clearance hole 112 and the second clearance hole 122, rotate the limiting member 13 so that the protrusion 1321 corresponds to the first clearance hole 112 and the second clearance hole 122, pull the limiting member 13 so that the protrusion 1321 moves out of the first clearance hole 112 and the second clearance hole 122, and the connecting post 132 moves out of the first through hole 111 and the second through hole 121, thereby removing the connecting piece 12. When installing the handle 14, the connecting piece 12 and the base piece 11 are stacked, aligning the first through hole 111 and the second through hole 121, and aligning the first clearance hole 112 and the second clearance hole 122. The connecting post 132 is passed through the first through hole 111 and the second through hole 121, and the protrusion 1321 is passed through the first clearance hole 112 and the second clearance hole 122. The limiting member 13 is rotated so that the protrusion 1321 abuts against the side of the base piece 11 opposite to the connecting piece 12. The detachable pull structure 1 and the pull head of this utility model make the handle 14 very simple to disassemble and install, and easy to operate.
[0050] Please refer to Figure 2 and Figure 4The substrate 11 has an annular recess 113 on its surface opposite to the connecting piece 12. The recess 113 surrounds and communicates with the first through hole 111, and a protrusion 1321 is located in the recess 113. The protrusion 1321 being located in the recess 113 prevents it from protruding from the substrate 11 and avoids the substrate 11 from not fitting snugly to clothing or other materials.
[0051] Please refer to Figure 2 and Figure 4 A limiting groove 114 is provided in the bottom wall of the clearance groove 113 to limit the protrusion 1321. During normal use, the protrusion 1321 is located in the limiting groove 114, which can prevent the limiting member 13 from rotating and prevent the protrusion 1321 from moving out of the first clearance hole 112 and the second clearance hole 122.
[0052] Please refer to Figure 2 The connecting post 132 is interference-fitted into the first through hole 111 to prevent the limiting member 13 from rotating freely and to prevent the limiting member 13 from falling off.
[0053] Please refer to Figure 1 The connecting piece 12 is rotatably mounted on the connecting post 132. The rotation of the connecting piece 12 drives the handle 14 to rotate, which can increase the fun.
[0054] Please refer to Figure 5 At the same time, please combine Figure 1 Along the radial direction of the second through hole 121, the connecting piece 12 is provided with a protruding connecting portion 123, which protrudes from the limiting piece 131. The handle 14 is connected to the connecting portion 123. With the above structure, the limiting piece 131 will not obstruct the connecting portion 123, and the fingers can pinch the connecting portion 123 to rotate, thereby causing the handle 14 to rotate, making operation convenient.
[0055] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 Two opposing first clearance holes 112 and two opposing second clearance holes 122 are provided. Two opposing protrusions 1321 are also provided. Two limiting grooves 114 are provided, with their arrangement direction perpendicular to the arrangement direction of the two first clearance holes 112. Both protrusions 1321 abut against the side of the substrate 11 opposite to the connecting piece 12, further preventing the limiting member 13 from detaching from the substrate 11. Furthermore, this structure ensures that the limiting grooves 114 are relatively far from the two first clearance holes 112, making it difficult for the protrusions 1321 to move out of the first clearance holes 112 and the second clearance holes 122 even if they detach from the limiting grooves 114.
[0056] Please refer to Figure 4 and Figure 5 Please also refer to Figure 2When the first clearance hole 112 is aligned with the second clearance hole 122, the extension direction of the handle 14 is consistent with the arrangement direction of the base 2 and the substrate 11. During normal use, the extension direction of the handle 14 is consistent with the arrangement direction of the base 2 and the substrate 11. When assembling or disassembling the handle 14, simply keep the handle 14 in its normal use position to align the first clearance hole 112 with the second clearance hole 122; the operation is simple.
[0057] Please refer to Figure 3 The connecting piece 12 and the handle 14 are integrally formed, which makes the connection between the connecting piece 12 and the handle 14 firm.
[0058] How to use the detachable pull structure 1 of the preferred embodiment of this utility model:
[0059] In the detachable pull structure 1 of this utility model, when disassembling the handle 14, the first avoidance hole 112 and the second avoidance hole 122 are aligned, and the limiting member 13 is pushed along the direction from the connecting piece 12 to the base plate 11, so that the protrusion 1321 disengages from the limiting groove 114. Then, the limiting member 13 is rotated 90° so that the protrusion 1321 corresponds to the first avoidance hole 112 and the second avoidance hole 122. The limiting member 13 is pulled in the opposite direction so that the protrusion 1321 moves out from the first avoidance hole 112 and the second avoidance hole 122, and the connecting post 132 moves out from the first through hole 111 and the second through hole 121, thereby removing the connecting piece 12. When installing the handle 14, the connecting piece 12 and the base piece 11 are stacked, and the first through hole 111 and the second through hole 121 are aligned, the first clearance hole 112 and the second clearance hole 122 are aligned, the connecting post 132 is passed through the first through hole 111 and the second through hole 121, the protrusion 1321 is passed through the first clearance hole 112 and the second clearance hole 122, and the limiting member 13 is rotated 90° so that the protrusion 1321 is located in the limiting groove 114.
[0060] This is the method of using the detachable pull structure 1 of this preferred embodiment.
[0061] The detachable pull structure of this utility model has a handle that is very simple to remove and install, and is easy to operate.
[0062] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be included within the scope of protection of the present invention.
