[0038] like Figures 1 to 3As shown, the present invention proposes a simplified compression-twist coupling, including a guide rail structure, a compression-twist mechanism connected to the guide rail structure, and a rotating shaft structure 400 connected to the compression-twist mechanism. The compression-twist mechanism is pressed to make it move linearly, and during this process, the compression-twist mechanism matched with the guide rail structure will rotate at the same time, which can drive the rotating shaft structure 400 connected to the compression-twist mechanism to rotate, so that the linear movement of the compression-twist mechanism can be converted into the rotational movement of the rotating shaft structure 400, which is simple and convenient.

[0039] Specifically, the guide rail structure may include a guide rail cylinder 100 with openings at both ends, and a spiral guide rail groove 112 is provided on the inner wall of the guide rail cylinder 100 along the axial direction of the guide rail cylinder 100. Moreover, the compression and twisting mechanism may include a compression and twisting block structure 200 sleeved in the guide rail cylinder 100, and a pushing structure 300 connected to the compression and twisting block structure 200 and protruding from the guide rail cylinder 100, one side of the compression and twisting block structure 200 is slidably arranged in the guide rail groove 112, and the other side is connected to the rotating shaft structure 400. By applying a thrust to the pushing structure 300, the compression and twisting block structure 200 can be moved linearly in the guide rail cylinder 100. Since one side of the compression and twisting block structure 200 is slidably connected to the spiral guide rail groove 112, the compression and twisting block structure 200 will rotate while moving linearly along the guide rail groove 112, thereby driving the rotating shaft structure 400 connected to the compression and twisting block structure 200 to rotate.

[0040] Furthermore, the compression and twisting block structure 200 may include a compression and twisting block 210 sleeved in the inner cavity of the guide rail cylinder 100, a guide rail shaft structure 220 fixedly connected to one side of the compression and twisting block 210, and a connecting shaft structure 230 connected to the other side of the compression and twisting block 210, the end of the guide rail shaft structure 220 is slidably clamped in the guide rail groove 112, and the connecting shaft structure 230 is fixedly connected to the rotating shaft structure 400. The compression and twisting block 210 is connected to the pushing structure 300, and the compression and twisting block 210 can be pushed linearly by pressing the pushing structure 300, so that the guide rail shaft structure 220 on one side of the compression and twisting block 210 spirally slides along the guide rail groove 112 on the guide rail cylinder 100, so that the compression and twisting block 210 rotates, which can drive the connecting shaft structure 230 to rotate together, thereby driving the rotating shaft structure 400 to rotate. At the same time, by respectively arranging the connecting shaft structure 230 and the guide shaft structure 220 on both sides of the compression-torsion block 210, the compression-torsion block 210 can be guided from both sides, so that the linear movement and rotational movement of the compression-torsion block 210 are more stable and reliable.

[0041] Moreover, if Figures 4 to 6As shown, the compression and twist block 210 may include a compression and twist main block 212 sleeved in the guide rail cylinder 100, an axial hole 2122 extending along the axial direction of the guide rail cylinder 100 is provided in the middle of the compression and twist main block 212, and a limiting groove 2124 extending along the radial direction of the guide rail cylinder 100 is provided on the side of the compression and twist main block 212, and the limiting groove 2124 is connected with the axial hole 2122. In addition, the above-mentioned rotating shaft structure 400 may include a rotating shaft body rotatably inserted into the axial hole 2122, and the connecting shaft structure 230 includes a connecting shaft body 232 with one end fixedly connected to the rotating shaft body and the other end slidably set in the limiting groove 2124. By inserting the rotating shaft body of the rotating shaft structure 400 into the compression and twist main block 212 of the compression and twist block 210, the space occupied by the rotating shaft body and the compression and twist block 210 can be reduced, and the structure is more compact. Moreover, by providing the limiting groove 2124 in the compression and twisting block 210, not only can the connecting shaft 232 of the connecting shaft structure 230 be arranged in the limiting groove 2124 to reduce the occupied space, but also the side walls on both sides of the limiting groove 2124 can be used to limit the connecting shaft 232, so that the compression and twisting main block 212 can use the side walls on both sides of the limiting groove 2124 to push the connecting shaft 232 during the rotation process, so that the connecting shaft 232 and the rotating shaft body rotate with the compression and twisting block 210. At the same time, when the compression and twisting block 210 moves linearly, the connecting shaft 232 can also slide linearly in the limiting groove 2124, so that the rotating shaft body will not (or less) slide linearly with the compression and twisting block 210. In addition, by providing the limiting groove 2124 on the compression and twisting block 210, the connecting shaft 232 is located in the compression and twisting block 210, so that the compression and twisting block 210 will not interfere with or hinder it during the linear movement and rotation process.

[0042] Furthermore, linear guide grooves 2126 may be provided on the side walls on both sides of the limit groove 2124 of the compression and twisting main block 212, and the connecting shaft structure 230 may further include a spherical guide roller 234 rotatably provided at the end of the connecting shaft body 232, and the guide roller 234 is slidably clamped in the guide groove 2126. By providing the linear guide groove 2126 on the side wall of the limit groove 2124, the guide roller 234 at the end of the connecting shaft body 232 can move linearly along the guide groove 2126, so that the connecting shaft body 232 and the rotating shaft body will not deflect and swing in the limit groove 2124, so that the rotation of the rotating shaft body is stable and reliable. In addition, by making the width of the limiting groove 2124 larger than the diameter of the connecting shaft 232, and making the diameter of the guide roller 234 larger than the width of the limiting groove 2124 and smaller than the diameter of the guide groove 2126, the guide roller 234 can be limited by the guide groove 2126, and the guide roller 234 can also slide freely in the guide groove 2126.

[0043] Moreover, the guide rail shaft structure 220 may include a guide rail shaft body 222 fixedly connected to one end of the compression and twisting block body 210, and a spherical guide rail roller 224 rotatably disposed at the end of the guide rail shaft body 222, and the guide rail roller 224 is slidably clamped in the guide rail groove 112. By arranging the guide rail roller 224 at the end of the guide rail shaft body 222, the guide rail roller 224 can slide along the guide rail groove 112, so that the guide rail shaft body 222 and the compression and twisting block body 210 can stably slide along the guide rail groove 112. In addition, the guide rail roller 224 can also be embedded in the guide rail groove 112, and the guide rail roller 224 can slide freely along the guide rail groove 112, so that the guide rail roller 224 and the guide rail shaft body 222 can be limited in the guide rail groove 112, so that the sliding and rotation of the compression and twisting block body 210 are more stable and reliable.

[0044] In addition, the above-mentioned compression and twisting main block 212 can be set to a flat block shape, and the inner cavity of the above-mentioned guide rail cylinder 100 can also be set to a flat cavity accordingly, and the compression and twisting main block 212 is set in the flat cavity. By setting the inner cavity of the guide rail cylinder 100 and the compression and twisting main block 212 to be flat, the inner cavity of the guide rail cylinder 100 can be used to limit the compression and twisting main block 212, which can not only make the compression and twisting main block 212 move linearly along the inner cavity of the guide rail cylinder 100, but also limit the rotation angle of the compression and twisting main block 212 to prevent the compression and twisting block 210 from rotating too much.

[0045] In addition, the above-mentioned compression and twisting mechanism may further include a compression and twisting reset structure 500 disposed at the end of the compression and twisting block structure 200, and the pushing structure 300 corresponds to the compression and twisting reset structure 500. In the process of pushing the compression and twisting block body 210 of the compression and twisting block structure 200 by the pushing structure 300, not only the compression and twisting block body 210 is moved linearly, but also the compression and twisting reset structure 500 is compressed. When the pushing structure 300 is no longer pushed, the compression and twisting block structure 200 is reset to its original position under the reaction force of the compression and twisting reset structure 500.

[0046] Specifically, the above-mentioned compression and twisting block 210 may also include a compression and twisting cylinder 214 protruding from the end of the compression and twisting main block 212 and extending out of the guide rail cylinder 100, and the pushing structure 300 is connected to the end of the compression and twisting cylinder 214. By arranging the compression and twisting cylinder 214 at the end of the compression and twisting block 210, it is not only convenient to connect with the pushing structure 300, but also convenient to arrange the compression and twisting reset structure 500 on the compression and twisting cylinder 214. Moreover, the above-mentioned compression and twisting reset structure 500 may include a first compression and twisting reset baffle 510 movably sleeved on one end of the compression and twisting cylinder 214 and fixedly clamped on the end of the guide rail cylinder 100, a second compression and twisting reset baffle 520 fixedly sleeved on the other end of the compression and twisting cylinder 214, and a compression and twisting reset spring 530 sleeved on the compression and twisting cylinder 214 and located between the first compression and twisting reset baffle 510 and the second compression and twisting reset baffle 520. In this way, when the pushing structure 300 is used to push the twist cylinder 214, the twist cylinder 214 will drive the twist main block 212 to move linearly toward the inner side of the guide cylinder 100. At this time, since the first twist reset baffle 510 is fixedly mounted on the guide cylinder 100 and will not move with the twist cylinder 214, the second twist reset baffle 520 fixedly mounted on the twist cylinder 214 will move with the twist cylinder 214, thereby compressing the twist reset spring 530 between the two. When the pushing force is no longer applied to the pushing structure 300 and the twist block 210, the second twist reset baffle 520 and the twist cylinder 214 will automatically reset under the elastic force of the twist reset spring 530, thereby automatically resetting the twist block 210 and the rotating shaft body.

[0047] In addition, the axis of the twist cylinder 214 can be colinear with the axis of the shaft hole of the guide rail cylinder 100, so that it is convenient to insert the end of the rotating shaft body into the twist cylinder 214. Moreover, the rotating shaft body can include a rotating shaft main shaft 410, and a rotating shaft head 420 located at the end of the rotating shaft main shaft 410, the rotating shaft head 420 extends into the cavity of the twist cylinder 214, and the connecting shaft body 232 is connected to the rotating shaft main shaft 410.

[0048] Moreover, the above-mentioned rotating shaft structure 400 may also include a rotating shaft reset structure 600 provided on the rotating shaft head 420, and the rotating shaft reset structure 600 is located in the cavity of the compression and twisting cylinder 214. It can be known from the above content that in the process of pushing the compression and twisting block 210 to move linearly by the pushing structure 300, the compression and twisting block 210 will rotate under the guidance of the guide groove 112 of the guide rail cylinder 100, and the rotating shaft body will not only rotate with the compression and twisting block 210, but also produce relative linear movement in the limiting groove 2124 of the compression and twisting main block 212, so that the rotating shaft body will be displaced in the axial direction. By providing the rotating shaft reset structure 600 on the rotating shaft head 420 of the rotating shaft body, the rotating shaft body can be reset to the original position when it is no longer affected by the pushing structure 300.

[0049] Furthermore, the above-mentioned shaft reset structure 600 may include a first shaft reset baffle 610 movably mounted on one side of the shaft head 420 and fixed on the inner wall of the compression cylinder 214, a second shaft reset baffle 620 fixedly mounted on the other end of the shaft head 420, and a shaft reset spring 630 mounted on the shaft head 420 and located on the first shaft reset baffle 610 and the second shaft reset baffle 620. In this way, when the pushing structure 300 is used to push the twist cylinder 214, the shaft body and the shaft head 420 will produce a linear displacement toward the inner side of the guide cylinder 100. At this time, since the first shaft reset baffle 610 is fixedly connected to the inner wall of the twist cylinder 214 and will not move with the shaft head 420, the second shaft reset baffle 620 fixedly sleeved on the shaft head 420 will move with the shaft head 420, thereby compressing the shaft reset spring 630 therebetween. When the pushing force is no longer applied to the pushing structure 300 and the twist block 210, the second shaft reset baffle 620 and the shaft head 420 will automatically reset under the elastic force of the shaft reset spring 630, thereby automatically resetting the shaft head 420 and the shaft body.

[0050] In addition, the pushing structure 300 may include a pushing head 310 sleeved on the end of the twisting cylinder 214, and a connecting pin 320 connecting and fixing the pushing head 310 and the twisting cylinder 214. The pushing head 310 of the pushing structure 300 may be connected and fixed to the end of the twisting cylinder 214 through the connecting pin 320, and the pushing head 310 may be connected to other structures so as to apply a linear thrust to the twisting cylinder.

[0051] In addition, the guide rail cylinder 100 may include a guide rail main cylinder 110, and a limiting cylinder 120 disposed at one end of the guide rail main cylinder 110, the guide rail groove 112 is opened on the inner wall of the guide rail main cylinder 110, the compression and twisting block 210 is movably arranged in the inner cavity of the guide rail main cylinder 110, and the limiting cylinder 120 is blocked and arranged outside the compression and twisting block 210. By arranging the limiting cylinder 120 at one end of the guide rail cylinder 100, the compression and twisting block 210 disposed in the guide rail cylinder 100 can be blocked and limited to prevent the compression and twisting block 210 from sliding out of the end of the guide rail cylinder 100. Moreover, by arranging the limiting cylinder 120, the rotating shaft body can also pass through the limiting cylinder 120 and penetrate into the compression and twisting block 210 in the guide rail main cylinder 10, so as to support and limit the rotating shaft.

[0052] In the technical solution proposed by the present invention, by setting a spiral guide groove on the guide rail cylinder, the compression and twisting block structure can be guided, and the linear movement of the compression and twisting block structure can be converted into the rotation of the shaft structure. Compared with the conventional technology of setting at least two spiral guide grooves to guide the compression and twisting block structure, the structure is simpler and the processing is simpler (processing multiple spiral guide grooves on the inner wall of the guide rail cylinder is more complicated, and the processing and assembly precision requirements are higher), which can greatly reduce the cost.

[0053] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
