Description

Technical Field

[0001] This utility model relates to the field of hardware accessories technology, and specifically to a hardware structure that allows an object to fall in a spiral. Background Technology

[0002] Linear and rotary motion are very common in mechanical transmissions, occurring in almost all kinds of equipment. A rotary cylinder is typically used to convert linear motion into rotary motion. Linear motion requires guiding constraints, while rotary motion relies on bearing support. Common conversion methods include using mechanisms such as gears and racks, sliders and connecting rods, or ball screws to achieve motion transformation.

[0003] Currently available transmission structures can convert linear motion into rotary motion. For example, Chinese utility model patent application CN222010637 U discloses a novel rotary cylinder, which includes: a cylinder barrel, a piston assembly slidably disposed within the cylinder barrel, an end cap sealed at one end of the cylinder barrel, and a connecting body sealed at the other end. The connecting body has a mounting groove, a gear rotatably disposed within the mounting groove, a rotating shaft fixed to the gear, and a telescopic shaft extending freely from the mounting groove. A telescopic shaft is threaded through the connecting body on one side of the mounting groove. By improving the end cap at one end of the cylinder and adding a gear and rack structure, the cylinder's linear output can be converted into rotary output, and the structure is more compact. A sealing element with a V-groove is provided on the piston. After compressed gas enters the V-groove, the sidewall of the V-groove expands to both sides, increasing the sealing between the piston and the cylinder barrel and improving the output torque.

[0004] However, this existing new rotary cylinder still has the following shortcomings: In this technical solution, the cylinder output is converted into rotational output through a gear and rack structure. However, the rotating shaft and the telescopic shaft are perpendicular to each other, failing to achieve coaxial circumferential rotation. This results in a large space requirement, making it unsuitable for some smaller structures (such as handheld structures).

[0005] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a hardware structure that allows items to fall in a spiral.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a hardware structure for causing an object to fall spirally, comprising: a spiral drive structure and a rotating structure driven by the spiral drive structure. The spiral drive structure includes a first sleeve, a first connecting cylinder disposed within the first sleeve, a spiral rod inserted at the front end of the first connecting cylinder, a rotating block spirally mounted on the spiral rod, a first spring sleeved around the spiral rod and used to push the rotating block, and a push handle inserted at the rear end of the first connecting cylinder. The front end of the spiral rod passes through the first sleeve and extends forward, and the rotating block is located outside the first sleeve. The rotating structure is provided with a second locking tooth for meshing with the rotating block. When the spiral rod moves, it drives the rotating block to rotate and drives the rotating structure to fall spirally.

[0008] Furthermore, in the above technical solution, the rotating structure includes a second sleeve sleeved outside the first sleeve, a rotating part disposed at the front end of the second sleeve, several decorative parts disposed on the rotating part and surrounding the second sleeve, a support part disposed on the rotating part and protruding forward, and a cover plate disposed on the rotating part.

[0009] Furthermore, in the above technical solution, the front end of the spiral rod passes through the second sleeve; the outer surface of the rotating part is curved, and the decorative part is inserted on the outer surface of the rotating part.

[0010] Furthermore, in the above technical solution, the second sleeve is cylindrical, and a second rotating groove for accommodating the rotating block is formed inside the second sleeve. The second locking teeth are distributed in the second rotating groove, and a third through hole for the spiral rod to pass through is opened in the middle of the second rotating groove.

[0011] Furthermore, in the above technical solution, the front end of the first connecting cylinder is provided with a first connecting groove for inserting the spiral rod. The inner wall of the first connecting groove is formed with a first rib and a second rib for engaging the spiral rod. The push handle is installed at the rear end of the first connecting cylinder by a first screw and a second screw. The first connecting cylinder is provided with a first through hole and a second through hole. Correspondingly, the push handle is provided with a first screw hole and a second screw hole. The first screw and the second screw pass through the first through hole and the second through hole respectively and are installed in the first screw hole and the second screw hole respectively.

[0012] Furthermore, in the above technical solution, the spiral rod includes an insertion section inserted into the first connecting cylinder, a spiral section integrally formed with the insertion section, and a through section formed at the front end of the spiral section. The insertion section has reverse teeth arranged on both sides to enhance the stability of the snap-fit. The spiral section is spiral-shaped to cooperate in driving the rotating block to rotate.

[0013] Furthermore, in the above technical solution, the rotating block is annular, and a first rotating hole is provided in the middle of the rotating block. The first rotating hole wall is formed with a first curved surface and a second curved surface for matching with the spiral segment. The front end face of the rotating block is provided with a first locking tooth for meshing with the second locking tooth.

[0014] Furthermore, in the above technical solution, the first sleeve is also formed with a protective cover structure that surrounds the decorative part of the rotating structure, and the protective cover structure is made of transparent material.

[0015] Furthermore, in the above technical solution, a positioning ring is fitted on the push handle, and a first annular groove for installing the positioning ring is provided on the protective cover structure.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: In this invention, the helical drive structure drives the helical rod axially by pushing the handle and the first spring. The rotation is transmitted through the rotating block, causing the rotating structure to spiral downwards. This converts linear motion into circumferential rotation within a limited space, making it suitable for application in various rotating structures. Furthermore, compared to existing structures, this invention directly drives the rotating block via the helical rod, improving transmission efficiency. This results in minimal mechanical vibration, significantly reduced wear between transmission components, and a longer service life. Attached Figure Description

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figures 1 to 9 As shown, this is a hardware structure for causing an object to spiral downwards. In one embodiment of this utility model, it includes: a spiral drive structure 1 and a rotating structure 2 driven by the spiral drive structure 1. The spiral drive structure 1 includes a first sleeve 11, a first connecting sleeve 12 disposed within the first sleeve 11, a spiral rod 13 inserted at the front end of the first connecting sleeve 12, a rotating block 14 spirally mounted on the spiral rod 13, a first spring 15 sleeved around the spiral rod 13 and used to push the rotating block 14, and a push handle 16 inserted at the rear end of the first connecting sleeve 12. The front end of the spiral rod 13 passes through the first sleeve 11 and extends forward, and the rotating block 14 is located outside the first sleeve 11. The rotating structure 2 is provided with a second locking tooth 202 for meshing with the rotating block 14. When the spiral rod 13 moves, it drives the rotating block 14 to rotate and, in turn, drives the rotating structure 2 to spiral downwards. Preferably, the spiral rod 13 is made of metal material, which has better wear resistance.

[0028] In this invention, the helical drive structure 1 drives the helical rod 13 to move axially by pushing the handle 16 and the first spring 15. The rotation is transmitted through the rotating block 14, causing the rotating structure 2 to spiral downwards. This converts linear motion into circumferential rotation within a limited space, making it suitable for application in various rotating structures. Furthermore, compared to existing structures, this invention directly drives the rotating block 14 via the helical rod 13, improving transmission efficiency. This results in minimal mechanical vibration and significantly reduced wear between transmission components, leading to a longer service life.

[0029] The spiral rod 13 includes an insertion section 131 inserted into the first connecting cylinder 12, a spiral section 132 integrally formed with the insertion section 131, and a through section 133 formed at the front end of the spiral section 132. The insertion section 131 has reverse teeth 1311 arranged on both sides to enhance the stability of the snap-fit. The spiral section 132 is spiral-shaped to cooperate in driving the rotating block 14 to rotate.

[0030] The rotating structure 2 includes a second sleeve 21 sleeved outside the first sleeve 11, a rotating part 23 disposed at the front end of the second sleeve 21, several decorative pieces 24 disposed on the rotating part 23 and surrounding the second sleeve 21, a support part 25 disposed on the rotating part 23 and protruding forward, and a cover plate 26 covering the rotating part 23. When the push handle 16 is manually pressed, the push handle 16 pushes the first connecting cylinder 12 forward and drives the spiral rod 13 to move forward in an axial linear motion. Simultaneously, the first spring 15 is compressed by the first connecting cylinder 12. Furthermore, the linear motion of the spiral rod 13 causes the spiral segment 132 to engage with the first curved surface 142 and the second curved surface 143 of the rotating block 14, driving the rotating block 14 to rotate and causing the second sleeve 21 to rotate, thereby causing the rotating structure 2 to spiral down and continue rotating. Furthermore, when the user's hand leaves the push handle 16, the first spring 15 automatically unfolds and supports the first connecting cylinder 12, driving the spiral rod 13 to move backward.

[0031] The front end of the spiral rod 13 passes through the second sleeve 21; the outer surface of the rotating part 23 is curved, and the decorative part 24 is inserted on the outer surface of the rotating part 23. Here, the through section 133 of the spiral rod 13 passes through the second sleeve 21.

[0032] The second sleeve 21 is cylindrical, and a second rotating groove 211 for accommodating the rotating block 14 is formed inside the second sleeve 21. The second locking teeth 202 are distributed in the second rotating groove 211, and a third through hole 213 for the spiral rod 13 to pass through is opened in the middle of the second rotating groove 211.

[0033] The first connecting cylinder 12 has a first connecting groove 121 at its front end for inserting the spiral rod 13. The inner wall of the first connecting groove 121 has a first rib 122 and a second rib 123 protruding for engaging the spiral rod 13. The push handle 16 is installed at the rear end of the first connecting cylinder 12 by a first screw 161 and a second screw 162. The first connecting cylinder 12 has a first through hole 125 and a second through hole 126. Correspondingly, the push handle 16 has a first screw hole 163 and a second screw hole 164. The first screw 161 and the second screw 162 pass through the first through hole 125 and the second through hole 126 respectively and are installed in the first screw hole 163 and the second screw hole 164 respectively.

[0034] A positioning ring 6 is fitted onto the push handle 16. The positioning ring 6 can block the first connecting cylinder 12 to prevent the first connecting cylinder 12 from accidentally coming off the first sleeve 11.

[0035] The rotating block 14 is annular in shape, with a first rotating hole 141 in the center. The wall of the first rotating hole 141 has a first curved surface 142 and a second curved surface 143 protruding from it for matching the helical segment 132. The front end face of the rotating block 14 has a first locking tooth 144 for meshing with the second locking tooth 202. Here, the meshing of the first locking tooth 144 with the second locking tooth 202 improves transmission efficiency.

[0036] In the second embodiment of this utility model, a protective cover structure 5 extends from the first sleeve 11 and surrounds the decorative piece 24 of the rotating structure 2. The protective cover structure 5 is made of transparent material. A first annular groove 56 is provided on the protective cover structure 5 for mounting the positioning ring 6. In this embodiment, when the rotating part 23 drives the decorative piece 24 to rotate, the protective cover structure 5 not only protects the decorative piece 24 from impacts but also has a transparent effect, increasing its aesthetic appeal and interest. Compared with the first embodiment, this embodiment differs only in the protective cover structure 5; the rest of the structure is the same and will not be described in detail here.

[0037] In summary, in this invention, the helical drive structure 1 drives the helical rod 13 to move axially by pushing the handle 16 and the first spring 15. The rotation is transmitted through the rotating block 14, causing the rotating structure 2 to fall in a helical motion. This converts linear motion into circumferential rotation within a limited space, making it suitable for application in various rotating structures. Furthermore, compared to existing structures, this invention directly drives the rotating block 14 via the helical rod 13, improving transmission efficiency. This results in minimal mechanical vibration, significantly reduced wear between transmission components, and a longer service life.
