Description

Technical Field

[0001] The present invention relates to the field of mechanical structures, and in particular to a manual telescopic rotating structure and a use method thereof. Background Art

[0002] In existing mechanical structures, if a component needs to rotate horizontally, it is necessary to apply power in the horizontal direction, such as using a motor in conjunction with a shaft rotor, or using a gear screw. However, for some structures that need to run in two directions at the same time, that is, when moving in the vertical direction, the components on one side rotate horizontally at the same time, it is currently impossible to complete them using a purely mechanical structure. This type of structure is widely used in mechanical synchronous processing, mechanical synchronous linkage structures, and various mechanical structures that require synchronous operation in multiple directions. For example, existing medical sperm extraction devices need to be combined with electronic components such as motor rotors. Not only do they have battery life issues, but they also have hidden dangers such as battery life and leakage. The use of too many electronic components is also prone to damage and difficult to repair.

[0003] Other synchronous motion structures, such as vertical expansion and contraction and lateral rotation, are controlled synchronously by two motors, or a single motor controls only one direction, while the other is mechanically controlled. However, neither of these control methods can achieve purely mechanical expansion and rotation synchronization. Furthermore, motor control methods have the disadvantages of high failure rates, low synchronization accuracy, increased energy loss, inconvenient cleaning (immersion) and the potential for bacterial growth, cumbersome operation, installation, and maintenance procedures, and a short service life. Summary of the Invention

[0004] The technical solution of the present invention is intended to at least partially address one of the technical problems in the related art. To this end, the main purpose of the present invention is to provide a manual telescopic rotation structure and method of use, aiming to address the problems of prior art synchronous bidirectional telescopic rotation structures, which require the use of a motor, suffer from short lifespan, complex structure, and low synchronization accuracy.

[0005] To achieve the above-mentioned object, the present invention provides a manual telescopic rotation structure, including a rotating telescopic assembly, wherein the rotating telescopic assembly includes a first assembly having an inner assembly inside; a second assembly sleeved on the first assembly; a third assembly sleeved on one side of the first assembly; a fourth assembly sleeve fixed to the first assembly sleeve is provided on one side of the second assembly sleeve, and one end of the fourth assembly sleeve extends toward one side of the second assembly sleeve and sleeved on the second assembly sleeve to form a fifth assembly sleeve for fixing the second assembly sleeve.

[0006] The first kit is provided with a through hole on the outside, and the inner kit is provided with a sliding part corresponding to the through hole. The inner wall of the second kit is provided with a spiral groove for driving the internal space of the first kit to rotate horizontally. The sliding part is located in the spiral groove after passing through the first kit. The first kit is a sleeve structure with an opening at at least one end. The opening of the first kit is provided with an internal contact part for vertical telescopic movement and driving the sliding part to move in the spiral groove. The internal contact part is a telescopic elastic part. Among them, the third kit is an infinitely rotating kit, and the number of parallel spiral grooves is 1-6.

[0007] As a further solution of the present invention, each kit of the rotary telescopic assembly is a cylindrical kit structure with holes at both ends, and the limiting parts at the end of each kit are detachable clip-on fixing structures.

[0008] As a further solution of the present invention, the sliding member includes a base arranged around one end of the inner sleeve, and a spring ball arranged on the base.

[0009] As a further solution of the present invention, a sealing member for fixing the inner wall of the inner contact member is clamped on one end of the inner sleeve.

[0010] As a further solution of the present invention, the outer ring of the sealing member is also surrounded by the sliding member for fixing with the outer edge of the first set and the third set.

[0011] As a further solution of the present invention, one end of the third set is provided with a groove that is snap-connected and rotatably connected to one end of the first set.

[0012] As a further solution of the present invention, a front cover and a rear cover are respectively provided at both ends of the rotating and telescopic assembly.

[0013] As a further solution of the present invention, the inner contact piece is a hollow piece with one end open, and the outer portion of the inner contact piece is in close contact with the inner sleeve and the inner portion of the first sleeve.

[0014] A method for using a manual telescopic rotating structure comprises the following steps:

[0015] The following usage:

[0016] When the inner contact member performs telescopic movement in the first set, due to its own telescopic characteristics and after being in close contact with the inner set, the sliding member provided on the inner set drives the spiral groove and the first set in sequence in the spiral groove. At this time, after the third set is fixed, the fourth set and the fifth set fix the second set, so that the inner contact member can simultaneously rotate in the vertical direction when performing telescopic movement.

[0017] When the inner contact moves one stroke into the first set, the above sets cooperate to rotate the inner contact one stroke. When the inner contact moves back in the opposite direction out of the first set, the above sets cooperate to rotate the inner contact one stroke in the opposite direction.

[0018] As a further solution of the present invention, the internal contact piece is detachably connected to the first kit, and when the internal contact piece is installed from the other end of the first kit, when the internal contact piece performs telescopic movement in the first kit, each of the kits cooperates to make the internal contact piece perform a stretching and rotating action.

[0019] The beneficial effects of the present invention are as follows:

[0020] The manual telescopic rotation structure and use method proposed in the present invention can realize a telescopic rotation integrated structure without the use of any electronic components, and is widely used in mechanical synchronous processing, mechanical synchronous linkage structures and various mechanical structures that require synchronous operation in multiple directions. The spiral groove is matched with the sliding parts and the sleeves, so that the internal contact parts connected thereto can rotate while performing telescopic movement. The internal contact parts can be hollow structures with a hole in the middle to facilitate connection with other structures, or they can be solid structures. And when performing telescopic movement, since the spiral groove has a length limit, the rotation is not in only one direction, but can automatically reset and circulate. The principle structure of this technical solution is simple and sophisticated, without a complex mechanical structure, easy to assemble and disassemble for maintenance, and the spiral structure can be changed according to different processing types or usage requirements.

[0041] The specific embodiments of the present invention are as follows:

[0042] Please see the attached Figures 1-8 ,

[0043] The main structure includes:

[0044] The rotating telescopic assembly 1 includes a first assembly 10 with an inner assembly 1000 inside; a second assembly 11 sleeved on the first assembly 10; a third assembly 12 sleeved on one side of the first assembly 10; a fourth assembly 13 fixed to the first assembly 10 is provided on one side of the second assembly 11, and one end of the fourth assembly 13 extends to one side of the second assembly 11 and sleeved on the second assembly 11 to form a fifth assembly 14 for fixing the second assembly 11. The first assembly 10 is provided with a through hole on the outside, and the inner assembly 1000 is provided with a sliding member 1 corresponding to the through hole. 001. The inner wall of the second assembly 11 is provided with a spiral groove 110 for driving the interior space of the first assembly 10 to rotate horizontally. The sliding member 1001 passes through the first assembly 10 and is located within the spiral groove 110. The first assembly 10 is a sleeve structure with an opening at least at one end. The opening of the first assembly 10 is provided with an internal contact member 2 for vertical telescopic movement and driving the sliding member 1001 to move within the spiral groove 110. The internal contact member 2 is a retractable elastic member. Among them, the third assembly 12 is an infinitely rotating assembly. The number of parallel spiral grooves 110 is 1-6. Each of the above-mentioned assemblies can be a cylindrical assembly with openings at both ends, and the material can be metal or plastic shell.

[0045] Here’s how it works:

[0046] This technical solution adopts a linear telescopic structure to convert the lateral rotation structure, that is, the spiral groove 110 and the first set 10 are driven by the telescopic movement of the inner contact 2. At this time, after the third set 12 is fixed (it can be fixed by hand or fixed by other fixing parts to make it immobile), since the fourth set 13 and the fifth set 14 fix the second set 11, the vertical rotation can be performed simultaneously when the inner contact 2 performs the telescopic movement.

[0047] The inner contact 2 can be a hollow structure with a central opening to facilitate connection to other structures, or it can be a solid structure. To facilitate connection to other structures, the inner contact 2 can be hollow in the middle, for example, with a threaded wall, so that other structures can simply rotate with the threaded wall. Alternatively, it can be configured as a removable connection, such as a slot structure. If the inner contact 2 is a solid structure, it can be fixedly connected to other external structures by welding or snapping, resulting in a non-removable structure.

[0048] The inner contact piece 2 can be configured to be a soft rubber material with expansion properties, and the external component forms an interference fit connection with the kit through the inner contact piece 2.

[0049] In addition, the spiral groove 110 arranged in the second set 11 is shaped to bend upward at the bottom, and each spiral groove 110 is arranged in parallel, and a limit structure is naturally formed at both ends of each spiral groove 110, allowing it to rotate and reverse within a certain range, rather than rotating in one direction.

[0050] The optimal number of spiral grooves 110 arranged in parallel is 3. If a single spiral groove 110 is used, although it can rotate, it is loose and unstable, and there will be a lot of noise. If 4-6 spiral grooves 110 are used, there will be a problem of large rotation resistance, or even no rotation.

[0051] The fifth assembly 14 and the second assembly 11 can be an integrated structure or a detachable structure.

[0052] In a preferred embodiment of the present invention, each kit of the rotary telescopic assembly 1 is a cylindrical kit structure with holes at both ends, and the limiting members at the ends of each kit are detachable clamping fixing structures.

[0053] This technical solution does not include a complex connection structure, and each kit can be fixed in a detachable snap-on manner, which is convenient for assembly, disassembly and maintenance.

[0054] In a preferred embodiment of the present invention, the sliding member 1001 includes a base 101A disposed around one end of the inner sleeve 1000, and a spring ball 101B disposed on the base 101A.

[0055] Sliding member 1001, like the spring ball on an everyday umbrella, consists of a base 101A and a spring ball 101B. It functions both as a snap-fit ​​assembly and as a sliding stopper, moving along spiral groove 110. The spiral displacement structure of this technical solution benefits from the coordinated rotation of sliding member 1001 and spiral groove 110.

[0056] In a preferred embodiment of the present invention, a sealing member 1002 for fixing the inner wall of the inner contact member 2 is clamped on one end of the inner sleeve 1000 .

[0057] The arrangement can strengthen the semi-fixed connection of the inner contact 2 and can also serve as a limiter for the end of the inner contact 2 to prevent the inner contact 2 from coming out from one side.

[0058] In addition, the sealing member further includes a clamping ring 10020 and a tightening member 10021 . The tightening member 10021 can be gathered inwardly so as to tighten the opening of the inner contact member 2 .

[0059] In a preferred embodiment of the present invention, a sliding member 1001 is also provided around the outer ring of the sealing member 1002 for fixing with the outer edge of the first set 10 and the third set 12 .

[0060] Since the third assembly 12 is an infinitely rotatable member, it needs to be snap-connected to the first assembly 10 while also being rotatable, so a sliding member 1001 is a more suitable solution. A groove 120 is provided at one end of the third assembly 12 to snap-connect and rotatably connect to one end of the first assembly 10. This groove 120 cooperates with the sliding member 1001 to achieve infinite rotation of the three assemblies on one side of the first assembly 10.

[0061] In a preferred embodiment of the present invention, a front cover 20 and a rear cover 21 are respectively provided at both ends of the rotating and telescopic assembly 1 .

[0062] The front cover 20 and the rear cover 21 are provided to play a sealing role. When not in use, the front cover 20 and the rear cover 21 are buckled onto the two ends of the rotating and telescopic component 1 to prevent the intrusion of moisture and dust.

[0063] In a preferred embodiment of the present invention, the inner contact 2 is a hollow member with one end open, and the exterior of the inner contact 2 is in close contact with the interior of the inner sleeve 1000 and the first sleeve 10. The inner contact 2 can be a hollow structure with a central opening to facilitate connection with other structures, or it can be a solid structure. To facilitate connection with other structures, the middle portion of the inner contact 2 can be hollow, for example, with a threaded wall, so that other structures can simply rotate with the threaded wall. Alternatively, the inner contact 2 can be configured as a slot structure, etc.

[0064] A method for using a manual telescopic rotating structure includes:

[0065] When the inner contact member 2 performs telescopic movement in the first sleeve 10, due to its own telescopic characteristics and close contact with the inner sleeve 1000, the sliding member 1001 provided on the inner sleeve 1000 drives the spiral groove 110 and the first sleeve 10 in sequence in the spiral groove 110. At this time, after the third sleeve 12 is fixed, the fourth sleeve 13 and the fifth sleeve 14 fix the second sleeve 11, so that the inner contact member 2 can simultaneously rotate in the vertical direction while performing telescopic movement.

[0066] When the inner contact 2 moves one stroke into the first set 10, the above sets cooperate to make the inner contact 2 rotate one stroke. When the inner contact 2 returns to the outside of the first set 10 in the opposite direction, the above sets cooperate to make the inner contact 2 rotate one stroke in the opposite direction.

[0067] In a preferred embodiment of the present invention, the inner contact 2 is detachably connected to the first set 10, and when the inner contact 2 is installed from the other end of the first set 10, when the inner contact 2 performs telescopic movement in the first set 10, the sets cooperate to make the inner contact 2 perform a stretching and rotating action.

[0068] The above are only preferred embodiments of the technical solution of the present invention, and do not limit the patent scope of the technical solution of the present invention. All equivalent structural transformations made by using the contents of the technical solution description and drawings of the present invention under the conception of the technical solution of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the present invention.
