Description

Technical Field

[0001] The utility model relates to the technical field of mechanical structures, in particular to a circumferential rotating extrusion structure. Background Art

[0002] Existing extrusion structures usually work using linear drives or fixed-size annular extrusion elements; however, these traditional structures show certain limitations when it comes to flexibly adjusting the channel cross-sectional area to make complex morphological changes to soft materials; for example, they find it difficult to achieve continuous and uniform deformation and extrusion in the circumferential direction, and often cannot effectively regulate the internal channel through simple rotational movements.

[0003] The shortcomings of the prior art include the following:

[0004] 1. Most of the existing extrusion structure designs do not include a mechanism that can dynamically adjust the diameter along the circumferential direction and extrude the internal channel. Especially in the application of the internal channel made of flexible materials, there is a lack of a technical solution that can both ensure the extrusion effect and prevent excessive deformation.

[0005] 2. Traditional extrusion structures are cumbersome in assembly and positioning, lacking effective radial positioning and fixing methods, which may lead to unstable relative positions between components, affecting overall performance and service life.

[0006] 3. In terms of operational convenience and flexibility, the extrusion structure in the prior art generally does not have the function of changing the channel cross-sectional area through rotational motion, which makes it inefficient when the flow rate or shape needs to be quickly adjusted.

[0007] Therefore, the prior art has deficiencies and needs further improvement. Utility Model Content

[0008] In view of the problems existing in the prior art, the utility model provides a circular rotating extrusion structure.

[0009] To achieve the above purpose, the specific scheme of the utility model is as follows:

[0010] The utility model provides a circumferential rotating extrusion structure, comprising:

[0011] An inner channel, made of a flexible material;

[0012] A spiral sleeve is sleeved on the outer side of the inner channel;

[0013] The spiral outer bracket is sleeved on the outer side of the spiral sleeve;

[0014] The knob is mounted on the rear end of the spiral sleeve through a bone position;

[0015] The spiral sleeve is cylindrical in shape as a whole, and a spiral hollow groove is provided on its side wall; when a rotational force is applied to the knob by hand, the knob drives the spiral sleeve to rotate and deform through the bone position, and its diameter changes from large to small along the radial direction;

[0016] After the spiral sleeve is rotated and deformed, its diameter becomes smaller and squeezes the inner channel arranged inside it.

[0017] Furthermore, a spiral protrusion is wound on the outer wall of the inner channel along its radial direction, and the spiral protrusion matches with the spiral hollow groove of the spiral sleeve and is embedded therein.

[0018] Furthermore, a spiral outer bracket is sleeved on the outer side of the spiral sleeve;

[0019] An arc-shaped hollow groove is provided on both sides of the tail end of the spiral outer bracket.

[0020] Four square positioning holes are evenly arranged between the two arc-shaped hollow grooves;

[0021] A first sliding block is provided on the side wall of the spiral sleeve at a position corresponding to the arc-shaped hollow groove;

[0022] A second sliding block is arranged at a position corresponding to the square positioning hole;

[0023] Four square positioning holes and the second slider are used to control the rotation size;

[0024] When the second slider is located in the four square positioning holes respectively, it is equivalent to four gears in sequence: large, medium, small, and smallest.

[0025] Furthermore, the front end of the spiral sleeve is also provided with a mounting annular disk;

[0026] The mounting annular disk is fixedly connected to a front fixing ring by at least two screws.

[0027] Furthermore, a spring block is arranged on the bone position arranged at the tail end of the spiral sleeve for fixing the knob.

[0028] Furthermore, the diameter of the spiral sleeve decreases from the front end to the rear end.

[0029] The technical solution of the utility model has the following beneficial effects:

[0030] 1. Innovative extrusion method: The circular rotating extrusion structure uses a spiral sleeve to design a spiral sleeve. The characteristic of the spiral sleeve that its diameter becomes smaller when it rotates and deforms can be used to continuously, evenly and accurately extrude the internal channel. This nonlinear extrusion method can not only adjust the channel cross-sectional area as needed and control the fluid flow, but also because the internal channel made of flexible material can adapt to deformation, it avoids damage or destruction caused by hard extrusion.

[0031] 2. Structural matching and stability: The spiral protrusions on the outer wall of the inner channel and the spiral hollow grooves of the spiral sleeve cooperate and inlay with each other, ensuring close contact and synchronous movement between the two during rotation, and improving the stability and sealing performance during the extrusion process.

[0032] 3. Convenience of assembly and positioning: The added spiral outer bracket and its arc-shaped hollow groove and square positioning hole, combined with the design of the first slider and the second slider, make the entire structure more accurate and convenient in installation and positioning, ensuring that the connections between the components are firm and not prone to loosening, thereby improving the overall operational reliability of the equipment.

[0033] 4. Modularity and flexibility: The front-end ring disk is connected to the front fixing ring with screws, and the tail bone is equipped with a spring fixing knob. This structural design is easy to disassemble and maintain, while enhancing the rigidity and durability of the overall structure, which is convenient for rapid adjustment and modification according to different application scenarios.

[0034] 5. Space optimization and efficiency improvement: The design of the spiral sleeve with a gradually decreasing diameter from the front end to the tail end saves space, optimizes power transmission during the working process, reduces energy consumption, and has the potential to improve the response speed and working efficiency of the device.

[0048] Combination Figure 1-Figure 2 As shown, the utility model provides a circumferential rotating extrusion structure, comprising: an inner channel 1, which is made of a flexible material; a spiral sleeve 2, which is sleeved on the outer side of the inner channel 1; a spiral outer bracket 3, which is sleeved on the outer side of the spiral sleeve 2; a knob 6, which is installed at the tail end of the spiral sleeve 2 through a bone position 5;

[0049] The spiral sleeve 2 is cylindrical as a whole, and a spiral hollow groove 201 is provided on its side wall; when a rotational force is applied to the knob 6 by hand, the knob 6 drives the spiral sleeve 2 to rotate and deform through the bone position 5, and its diameter changes from large to small along the axial direction; after the spiral sleeve 2 rotates and deforms, its diameter becomes smaller and squeezes the inner channel 1 set inside it.

[0050] A spiral protrusion 101 is wound on the outer wall of the inner channel 1 along its axial direction, and the spiral protrusion 101 matches with the spiral hollow groove 201 of the spiral sleeve 2 and is embedded therein.

[0051] A spiral outer bracket 3 is also sleeved on the outer side of the spiral sleeve 2; an arc-shaped hollow groove 301 is respectively arranged on both sides of the tail end of the spiral outer bracket 3, and four square positioning holes 302 are evenly arranged between the two arc-shaped hollow grooves 301; a first slider 202 is arranged at a position corresponding to the arc-shaped hollow groove 301 on the side wall of the spiral sleeve 2; a second slider 203 is arranged at a position corresponding to the square positioning hole 302; the four square positioning holes 302 and the second slider 203 are used to control the rotation size; when the second slider 203 is respectively located in the four square positioning holes 302, it is equivalent to four gears in sequence: large, medium, small, and smallest.

[0052] The front end of the spiral sleeve 2 is also provided with a mounting annular disk 303, which is fixedly connected to a front fixing ring 4 by at least two screws. A spring block is provided on the bone position 5 provided at the rear end of the spiral sleeve 2 for fixing the knob. The diameter of the spiral sleeve 2 decreases from the front end to the rear end.

[0053] The principle of this utility model is as follows:

[0054] 1. Core components and deformation mechanism: The spiral sleeve 2 changes its diameter by rotation. It is cylindrical as a whole and has a spiral hollow groove 201 on the side wall. When a rotational force is applied to the spiral sleeve 2, due to its design characteristics, its diameter will change from large to small along the axial direction.

[0055] 2. Inner channel 1 and matching method: There is an inner channel 1 made of flexible material inside, and the outer wall of the channel is provided with spiral protrusions 101 matching the hollow grooves of the spiral sleeve 2 along the axial direction; when the spiral sleeve 2 rotates and deforms, these spiral protrusions 101 will be embedded in the spiral hollow grooves 201, and as the diameter of the spiral sleeve 2 decreases, a uniform and controllable extrusion effect is produced on the inner channel 1.

[0056] 3. Radial positioning and fixation: In order to ensure the stability of the entire structure during operation, a spiral outer bracket 3 is also provided on the outside of the spiral sleeve 2. The arc-shaped hollow grooves 301 on both sides of the tail end of the spiral outer bracket 3 and the square positioning hole 302 in the middle are combined with the first and second sliders 203 on the spiral sleeve 2 to achieve radial positioning and fixation, thereby preventing the spiral sleeve 2 from axial or radial movement during the extrusion process.

[0057] 4. Assembly and connection: The front end is connected to the front fixing ring 4 by installing the annular disk 303 and screws to facilitate stable assembly with the driving mechanism or other equipment; the rear end is provided with a bone position 5 and a spring block for fixing the knob, ensuring the integrity and sealing of the structure.

[0058] 5. Operation and application: When the user drives the spiral sleeve 2 to rotate in some way, the internal channel 1 is compressed due to its design that the diameter gradually decreases from the front end to the rear end, thereby adjusting the channel cross-sectional area, controlling the fluid flow or changing the material form to meet specific application requirements.

[0059] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the protection scope of the utility model.
