Description

Technical Field

[0001] This utility model provides a sleeve structure, and more particularly a sleeve structure that can be driven to rotate in conjunction with various hand tools. Background Technology

[0002] With technological advancements, when operating tools such as screws, users often use socket wrenches to hold the tools in place, making assembly and disassembly easier and more convenient. For example, a user can slip a socket wrench over the tool, hold the wrench in place, and use the wrench to rotate the socket, thereby completing the assembly and disassembly of the tool.

[0003] Although many types of sockets are available on the market that can be used with different hand tools, a single socket can only be driven by one type of hand tool. In different usage scenarios, different sockets and hand tools still need to be used, and users must prepare multiple sets of sockets to cope with different space limitations, which leads to inconvenience in use and burden in carrying.

[0004] In view of this, improving the versatility of driving sleeve rotation has become the goal of relevant industry players. Utility Model Content

The positioning bead is connected to one end of the elastic element, and the positioning bead partially protrudes from the concave space.

[0012] Another embodiment of this utility model provides a sleeve structure, which includes a sleeve body, a polygonal driving structure, and a driving hole.

[0055] The following description, with reference to the accompanying drawings, outlines several embodiments of the present invention. For clarity, numerous practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the scope of the present invention. In other words, these practical details are not essential in some embodiments of the present invention. Furthermore, for the sake of simplicity, some conventional structures and elements will be depicted schematically in the drawings; and repeated elements may be denoted using the same reference numerals.

[0056] Please see Figure 1 and Figure 2 , Figure 1 An exploded view of the sleeve structure 100 according to the first embodiment of this utility model is shown. Figure 2 Draw Figure 1 A perspective view of the sleeve structure 100. The sleeve structure 100 includes a sleeve body 110 and a polygonal drive structure 120. The sleeve body 110 has a first socket hole 111 and a second socket hole 112. The first socket hole 111 is located at one end of the sleeve body 110 along a central axis of the sleeve structure 100, and the second socket hole 112 is located at the other end of the sleeve body 110 along the central axis of the sleeve structure 100. The first socket hole 111 can be used to engage and drive the sleeve structure 100 to rotate, such as a four-corner wrench, while the second socket hole 112 can be used to engage and drive tools such as screws.

[0057] A polygonal drive structure 120 is disposed around an outer annular wall of the sleeve body 110 and surrounds the first socket hole 111. Specifically, the sleeve body 110 may include a drive end face 113, which may be perpendicular to the central axis, and the first socket hole 111 may pass through the drive end face 113. The polygonal drive structure 120 may include a plurality of teeth 121, each tooth 121 extending from the drive end face 113 in a direction parallel to the central axis, and each tooth 121 may be a rectangular column with its long side parallel to the central axis. Thus, the sleeve structure 100 with teeth 121 can be fitted with a ratchet wrench and driven to rotate, therefore the first socket hole 111 and the polygonal drive structure 120 can be used with different hand tools, increasing the diversity of the drive methods of the sleeve structure 100.

[0058] The sleeve structure 100 may further include a recessed space 122, an elastic element 123, and a positioning bead 124. The recessed space 122 is radially disposed on the polygonal drive structure 120 along the central axis. The elastic element 123 is disposed in the recessed space 122. The positioning bead 124 is connected to one end of the elastic element 123, and part of the positioning bead 124 protrudes out of the recessed space 122. When a hand tool (not shown) is engaged in the polygonal drive structure 120, the positioning bead 124 can push against the engagement hole of the hand tool, which facilitates engagement and fixation, making the hand tool engagement more stable.

[0059] exist Figure 2 In this embodiment, the depth of the first socket 111 and the second socket 112 may be greater than the height of the hand tool or tool to be engaged, so as to prevent the hand tool from exceeding the first socket 111 and reaching the second socket 112 when it engages with the first socket 111, thus pushing against the tool and causing the tool to detach from the second socket 112. However, the present invention is not limited thereto.

[0060] Please refer to Figure 3 , Figure 3 Draw Figure 1 A side view of the sleeve structure 100 is shown. The sleeve structure 100 has a maximum height L1 along its central axis, and the polygonal drive structure 120 has an axial length L2 along its central axis, wherein the axial length L2 is less than or equal to half of the maximum height L1. Furthermore, the axial length L2 can be between 34% and 42% of the maximum height L1. This ensures that the sleeve body 110 and the polygonal drive structure 120 have an appropriate proportion.

[0061] exist Figure 3 In this design, the multi-angle drive structure 120 has a first width L3 radially along its central axis, and the sleeve body 110 has a second width L4 radially along its central axis, with the first width L3 being greater than the second width L4. Therefore, when a ratchet wrench is used to set and drive the sleeve structure 100 to rotate, the applied lever arm is greater than the resisting lever arm, achieving a labor-saving effect.

[0062] Please see Figure 4 and Figure 5 , Figure 4 A three-dimensional schematic diagram illustrating the sleeve structure 200 of the second embodiment of this utility model is shown. Figure 5 Draw Figure 4 Another three-dimensional schematic diagram of the sleeve structure 200.

Figure 1The sleeve body 110 of the sleeve structure 100 is similar to that of the polygonal drive structure 120, and the similarities will not be described again here. It is worth noting that in the second embodiment, each tooth 221 of the polygonal drive structure 220 can be in the shape of a pointed triangular prism, so that the end face of the polygonal drive structure 220 that is flush with the drive end face 213 is in the shape of a multi-pointed star.

[0063] Furthermore, the sleeve structure 200 may include a drive hole 230, which passes through the sleeve body 210 and communicates with the second socket hole 212 radially along the central axis. The drive hole 230 allows a one-handed tool (not shown) to be engaged by the side of the sleeve body 210. The user can apply force from the side of the sleeve body 210 to drive the sleeve structure 200 to rotate, thereby enabling the sleeve structure 200 to be used to assemble and disassemble tools even in spaces with insufficient vertical height.

[0064] Please see Figure 6 The diagram illustrates a three-dimensional view of the sleeve structure 300 according to the third embodiment of the present invention. Figure 6 The configuration relationship between the sleeve body 310 of the sleeve structure 300 and the polygonal drive structure 320 is the same as that of the sleeve structure 300. Figure 4 The sleeve body 210 of the sleeve structure 200 is similar to that of the polygonal drive structure 220, and the similarities will not be described again here. In particular, in the third embodiment, the drive hole 330 is radially inserted into the polygonal drive structure 320 along the central axis, thereby communicating with the first socket hole 311.

[0065] It should be noted that the driving hole 230 in the second embodiment is connected to the second socket hole 212, while the driving hole 330 in the third embodiment is connected to the first socket hole 311. That is to say, the driving holes 230 and 330 can be changed in their positions according to actual needs, so as to facilitate operation by users in different spaces. Therefore, this utility model is not limited to the contents disclosed in the above embodiments.

[0066] Please see Figure 7 The diagram illustrates a three-dimensional view of the sleeve structure 400 according to the fourth embodiment of this utility model.

Figure 6 The sleeve body 310 of the sleeve structure 300 is similar to the polygonal drive structure 320, and the similarities will not be repeated here. In particular, in the fourth embodiment, the polygonal drive structure 420 may further include a step portion 422, which is recessed in at least one of the teeth 421 and extends upward from the lower edge of the polygonal drive structure 420, forming a shape such as... Figure 7 The flat surface shown, and the polygonal drive structure 420 adjacent to the drive end face 413 retains the complete polygonal structure, which can be combined with different hand tools.

[0067] To further explain, the drive hole 430 can be radially inserted along the central axis into the step portion 422 of the polygonal drive structure 420 and the sleeve body 410, thereby communicating with the first socket hole 411. The method by which the user drives the sleeve structure 400 to rotate using the drive hole 430 is similar to that of the aforementioned sleeve structure 200 and sleeve structure 300, and will not be described in detail here. Furthermore, the step portion 422 can be formed on opposite sides of the polygonal drive structure 420, for the open-end wrench to clamp and drive the sleeve structure 400 to rotate.

[0068] Please see Figure 8 The diagram illustrates a three-dimensional view of the sleeve structure 500 according to the fifth embodiment of this utility model.

Figure 4 The sleeve body 210, polygonal drive structure 220, and drive hole 230 of the sleeve structure 200 are similar, and the similarities will not be described again here. In particular, in the fifth embodiment, the tooth 521 of the polygonal drive structure 520 may further include a plurality of first teeth 522 and a plurality of second teeth 523.

[0069] To further explain, each first tooth 522 has a first radial length L5 along the central axis, and each second tooth 523 is connected to the first tooth 522, with a second radial length L6 along the central axis. The first radial length L5 is greater than the second radial length L6. By providing the first teeth 522 and the second teeth 523, the friction between the ratchet wrench and the multi-angle drive structure 520 can be increased, thereby improving the firmness of the connection between the ratchet wrench and the socket structure 500.

[0070] Please see Figure 9 The diagram illustrates a three-dimensional schematic of the sleeve structure 600 according to the sixth embodiment of this utility model. Figure 9 The configuration relationship of the sleeve body 610, the polygonal drive structure 620, and the drive hole 630 of the sleeve structure 600 is all related to... Figure 4 The sleeve body 210, polygonal drive structure 220, and drive hole 230 of the sleeve structure 200 are similar, and the similarities will not be described again here. In particular, the polygonal drive structure 620 includes six teeth 621, each of which can be cylindrical, and two adjacent teeth 621 can be connected by a curved surface, so that the end face of the polygonal drive structure 620 that is flush with the drive end face 613 has a hexagonal flower shape, so that different hand tools can be combined.
