Description

Technical Field

[0001] The present disclosure relates to a positioning structure and a positioning device, and in particular to a positioning structure and a positioning device with a quick disassembly and assembly design. Background Art

[0002] The common positioning structure is to fix the target object by the engagement of the external thread of the bolt with the internal thread of the screw hole. Once there is a need to disassemble or assemble the target object, the operator must use a tool (such as a screwdriver or a wrench) to loosen the bolt to disassemble the target object, or tighten the bolt to fix the target object. However, due to space limitations or interference from obstacles, the tool (such as a screwdriver or a wrench) is not easy to reach the working position (i.e., the head of the bolt), or even if the tool can be extended to the working position, the operator cannot or has difficulty applying force to loosen or tighten the bolt, resulting in time-consuming and difficult disassembly and assembly operations. Summary of the invention

[0003] The purpose of the present invention is to provide a positioning structure and a positioning device that are easy and quick to assemble and disassemble.

[0004] The present disclosure proposes a positioning structure, including a first bushing, a positioning washer, a bolt and a button. The first bushing has a first opening and a second opening that are opposite to and connected to each other. The positioning washer is fixed in the first bushing, and includes a positioning hole corresponding to the first opening and a plurality of positioning springs arranged circumferentially in the positioning hole. The bolt is suitable for inserting into the first bushing from the first opening and passing through the positioning hole. At least part of the plurality of positioning springs is engaged with the thread of the bolt, so that the bolt is fixed by the positioning washer. The button is inserted into the first bushing from the second opening and contacts the plurality of positioning springs. The button is suitable for sliding toward the first opening and pushing the plurality of positioning springs to produce elastic deformation, so that the plurality of positioning springs are separated from the thread, causing the bolt to loosen from the positioning washer.

[0005] According to one embodiment of the present disclosure, the button has a through hole corresponding to the positioning hole, and the bolt is suitable for passing through the through hole.

[0006] According to one embodiment of the present disclosure, a second bushing is inserted into the first bushing from the second opening and pressed against the positioning washer, wherein the second bushing is fixed in the first bushing, and the button is slidably inserted into the second bushing on one side relative to the positioning washer.

[0007] According to one embodiment of the present disclosure, the second bushing has a first through hole corresponding to the second opening and a second through hole connected to the first through hole, and the second through hole is located between the positioning washer and the first through hole, and the button is inserted into the second through hole via the first through hole, and the button includes a sliding portion arranged in the second through hole and an unlocking portion connected to the sliding portion, wherein the unlocking portion is located between the sliding portion and the positioning washer, and the unlocking portion contacts the plurality of positioning springs.

[0008] According to one embodiment of the present disclosure, an aperture of the first through hole is smaller than an aperture of the second through hole, and an outer diameter of the unlocking portion is smaller than an outer diameter of the sliding portion, and the outer diameter of the sliding portion is larger than the aperture of the first through hole.

[0009] The present disclosure provides a positioning device, including a first positioning member, a positioning structure and a second positioning member. The first positioning member includes a mounting hole. The positioning structure is suitable for being installed in the mounting hole. The positioning structure includes a first bushing fixed in the mounting hole, a positioning washer fixed in the first bushing, a bolt and a button. The first bushing has a first opening and a second opening that are opposite and connected to each other. The positioning washer includes a positioning hole corresponding to the first opening and a plurality of positioning springs arranged circumferentially in the positioning hole. The button is inserted into the first bushing from the second opening and contacts the plurality of positioning springs of the positioning washer. The second positioning member has a bolt hole, wherein the bolt is suitable for passing through the bolt hole and inserting into the positioning structure in the mounting hole corresponding to the bolt hole. The bolt is inserted into the first bushing from the first opening and passes through the positioning hole of the positioning washer. At least part of the plurality of positioning springs of the positioning washer is engaged with the thread of the bolt, so that the bolt is fixed by the positioning washer, and the head of the bolt presses against the second positioning member to fix the second positioning member to the first positioning member. When the button slides toward the first opening and pushes the plurality of positioning springs to generate elastic deformation, the plurality of positioning springs are separated from the threads, causing the bolt to be loosened from the positioning washer, and the second positioning member to be loosened from the first positioning member.

[0010] Based on the above, the operator can quickly fix the second positioning member to the first positioning member or remove the second positioning member from the first positioning member through the two-way pressing mechanism.

[0046] Figure 1 is a schematic diagram of a positioning device according to an embodiment of the present disclosure. Figure 2 yes Figure 1 A partial cross-sectional diagram of the positioning device along section line II. Please refer to Figure 1 and Figure 2 In this embodiment, the positioning device 10 may include a first positioning member 11, a plurality of positioning structures 100, and a second positioning member 12, wherein the first positioning member 11 has a mounting hole 11a, and the positioning structure 100 is installed in the mounting hole 11a. In addition, the second positioning member 12 has a bolt hole 12a, wherein the bolt hole 12a is aligned with the mounting hole 11a, and the second positioning member 12 is fixed to the first positioning member 11 by the positioning structure 100 in the mounting hole 11a aligned with the bolt hole 12a.

[0047] For example, the first positioning member 11 may have a plurality of mounting holes 11a, and each mounting hole 11a is provided with a positioning structure 100. The operator may adjust the position (e.g., height) of the second positioning member 12 according to the requirements, so that the bolt hole 12a is aligned with any mounting hole 11a, and the second positioning member 12 is fixed to the first positioning member 11 by the positioning structure 100 in the mounting hole 11a aligned with the bolt hole 12a.

[0048] Figure 3 It is a schematic diagram of a positioning structure according to an embodiment of the present disclosure. Figure 4 yes Figure 3 Exploded diagram of the positioning structure. Please refer to Figures 2 to 4 The positioning structure 100 includes a first bushing 110, a positioning washer 120, a bolt 130 and a button 140, wherein the first bushing 110 is fixed in the mounting hole 11a and has a first opening 111 and a second opening 112 that are opposite to and communicate with each other. In addition, the positioning washer 120 is fixed in the first bushing 110 and includes a positioning hole 121 corresponding to the first opening 111 and a plurality of positioning springs 122 arranged circumferentially in the positioning hole 121.

[0049] In the process of fixing the second positioning member 12 to the first positioning member 11, the operator first aligns the bolt hole 12a with the mounting hole 11a, especially with the first opening 111 of the first bushing 110 fixed in the mounting hole 11a, then aligns the bolt 130 with the bolt hole 12a and presses the bolt 130 along the first direction 101, so that the bolt 130 passes through the bolt hole 12a and the first opening 111 in sequence to be inserted into the first bushing 110, and further passes through the positioning hole 121 of the positioning washer 120.

[0050] In detail, the bolt 130 includes a head 131 and a thread 132. The operator continuously presses the bolt 130 along the first direction 101 so that the head 131 presses against the second positioning member 12. On the other hand, the bolt 130 passing through the positioning hole 121 generates structural interference with the plurality of positioning spring pieces 122, and at least a portion of the plurality of positioning spring pieces 122 is engaged with or embedded in the thread 132, so that the bolt 130 is fixed by the positioning washer 120. When the head 131 presses against the second positioning member 12 and the bolt 130 is fixed by the positioning washer 120, the second positioning member 12 is clamped and fixed between the head 131 and the first positioning member 11.

[0051] Please refer to Figure 2 and Figure 4 The positioning structure 100 further includes a second bushing 150 inserted into the first bushing 110 from the second opening 112 to press against the positioning washer 120. The second bushing 150 is fixed in the first bushing 110 to fix the positioning washer 120 in the first bushing 110 and prevent the positioning washer 120 from being offset in the first bushing 110. For example, the positioning washer 120 is fixed between the first opening 111 and the second bushing 150, wherein the outer diameter of the positioning washer 120 and the outer diameter of the second bushing 150 are substantially equal to the diameter of the second opening 112, and larger than the diameter of the first opening 111.

[0052] On the other hand, the button 140 is inserted into the first bushing 110 from the second opening 112, specifically, into the second bushing 150 located in the first bushing 110, and contacts the plurality of positioning springs 122 of the positioning washer 120 pressed by the second bushing 150. In detail, the button 140 is slidably arranged in the second bushing 150 on one side relative to the positioning washer 120, and includes a pressing portion 141 located outside the first bushing 110 and the second bushing 150, and an unlocking portion 143 located inside the second bushing 150 and connected to the sliding portion 142. The pressing portion 141 and the unlocking portion 143 are respectively located on opposite sides of the sliding portion 142, wherein the unlocking portion 143 is located between the sliding portion 142 and the positioning washer 120, and the unlocking portion 143 is in contact with the plurality of positioning springs 122.

[0053] The button 140 has a through hole 144 penetrating the pressing portion 141, the sliding portion 142 and the unlocking portion 143, wherein the through hole 144 is aligned with the positioning hole 121 of the positioning washer 120, and the bolt 130 passes through the through hole 144. When the bolt 130 is not fixed by the positioning washer 120, the bolt 130 can slide in the through hole 144.

[0054] Figure 5 and Figure 6 yes Figure 2 Schematic diagram of the disassembly process of the bolt and the second positioning member. Figure 2 , Figure 5 and Figure 6 As shown, when the operator presses the pressing portion 141 along the second direction 102 opposite to the first direction 101 , the button 140 slides toward the first opening 111 and pushes the plurality of positioning springs 122 to generate elastic deformation through the unlocking portion 143 .

[0055] like Figure 5 and Figure 6 As shown, the plurality of positioning springs 122 are separated from the threads 132 after elastic deformation to release the structural interference of the positioning washer 120 on the bolt 130, so that the bolt 130 is loosened from the positioning washer 120. When the bolt 130 is loosened from the positioning washer 120, the second positioning member 120 is not pressed by the head 131 of the bolt 130 to be loosened from the first positioning member 11, and the operator can remove the bolt 130 and the second positioning member 12 along the second direction 102.

[0056] like Figure 5 and Figure 6 As shown, once the operator removes the pressing force applied to the button 140 , the elastic restoring force of the plurality of positioning springs 122 can push the button 140 to slide along the first direction 101 back to the initial position.

[0057] like Figure 2 , Figure 5 and Figure 6 As shown, the operator can quickly fix the second positioning member 12 to the first positioning member 11 or remove the second positioning member 12 from the first positioning member 11 through the two-way pressing mechanism. In other words, the positioning structure 100 and the positioning device 10 using the positioning structure 100 are not only convenient for the operator to quickly disassemble and assemble, but also the disassembly and assembly mechanism is quite simple and intuitive.

[0058] like Figure 2 and Figure 4As shown, in this embodiment, the second bushing 150 has a first through hole 151 corresponding to the second opening 112 and a second through hole 152 connected to the first through hole 151, and the second through hole 152 is located between the positioning washer 120 and the first through hole 151. In detail, the button 140 is inserted into the second through hole 152 via the first through hole 151, wherein the sliding portion 142 and the unlocking portion 143 are located in the second through hole 152, and the sliding portion 142 is closer to the first through hole 151 than the unlocking portion 143.

[0059] like Figure 4 As shown, the aperture D1 of the first through hole 151 is smaller than the aperture D2 of the second through hole 152, and the outer diameter D3 of the unlocking portion 143 is smaller than the outer diameter D4 of the sliding portion 142. In addition, the outer diameter D4 of the sliding portion 142 is smaller than the aperture D2 of the second through hole 152 and larger than the aperture D1 of the first through hole 151, so as to facilitate the sliding of the button 140 relative to the second bushing 150 and prevent the button 140 from slipping off the second bushing 150 via the first through hole 151.

[0060] In summary, the operator can quickly fix the second positioning member 12 to the first positioning member 11 or remove the second positioning member 12 from the first positioning member 11 through the two-way pressing mechanism. In other words, the positioning structure 100 and the positioning device 10 using the positioning structure 100 of the present disclosure are not only conducive to the operator's quick assembly and disassembly, but also the assembly and disassembly mechanism is simple and intuitive.

[0061] Although the present disclosure has been disclosed as above by way of embodiments, it is not intended to limit the present disclosure.
