Technical Field
[0001] This utility model relates to the technical field of creative product creation tables, and in particular to a creative product creation table. Background Technology
[0002] A potter's wheel is an important tool used for shaping clay on a potter's wheel in pottery making. It uses a motor to rotate a turntable, and the potter places clay in the center of the turntable. As the turntable rotates, the potter shapes the clay by hand into various forms, such as bowls, bottles, and jars. The speed of the potter's wheel is adjustable, allowing the potter to control it according to their own operating habits and the requirements of their work.
[0003] Other devices use the turntable's own gravity and inertia to make it rotate like a flywheel. However, due to bearing friction, the turntable needs to be pushed intermittently during the pottery operation to keep it within a reasonable speed range. This places high demands on the operator's coordination and experience.
[0004] Modern pottery is not only a professional art form, but also a cultural and recreational activity in many places. Traditional pottery making tables require motors to drive them, which greatly increases the cost of the equipment and limits its working environment. In some streets, electricity restrictions often limit the use of the equipment.
[0005] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content
[0006] A creative product creation table, comprising;
[0007] A production table is provided with a rotating outer sleeve in the middle of the production table, a rotating inner sleeve in the middle of the production table, and a foot-operated driver at the bottom of the production table. The foot-operated driver converts linear reciprocating motion into rotation and drives the rotating outer sleeve to rotate.
[0008] The outer wall of the rotating inner sleeve is provided with ratchet teeth to disengage from the rotating outer sleeve and transmit unidirectional power through the rotating outer sleeve to the rotating inner sleeve, causing the rotating inner sleeve to drive the turntable fixed on the top of the rotating inner sleeve to rotate.
[0009] Preferably, a rotating shaft is coaxially fixed at the bottom of the rotating outer sleeve, a driven bevel gear is coaxially fixed at the lower end of the rotating shaft, and a driving bevel gear is coaxially fixed at the output shaft end of the pedal-type drive, the driving bevel gear and the driven bevel gear meshing.
[0010] Preferably, the pedal-type actuator includes a fixed cylinder and a movable cylinder that slides vertically within the fixed cylinder. The fixed cylinder contains a return spring that pushes a one-way rack fixed to the top wall of the movable cylinder upwards to reset it. A first turntable is rotatably mounted within the fixed cylinder. A first ratchet is hinged to the side of the first turntable via a first pivot, and a limiting post is fixed to the first turntable. The limiting post restricts the first ratchet from rotating counterclockwise around the first pivot. Thus, when the one-way rack moves downwards, it can drive the first turntable to rotate through tooth meshing. When the one-way rack resets upwards, the first ratchet rotates clockwise around the first pivot, causing the teeth to misalign and preventing the first turntable from reversing. A pulling protrusion is also fixed to the first turntable, and a spring connects the pulling protrusion and the first ratchet. The spring's K-value is less than the force required to drive the first turntable.
[0011] Preferably, the inner wall of the rotating outer sleeve is provided with a ring array of fixed teeth, and a one-way rack is hinged to the outer countersunk position of the rotating inner sleeve by a return spring. When the rotating outer sleeve rotates clockwise, the rotating outer sleeve and the one-way rack mesh with each other. A first turntable is fixed on the one-way rack and abuts against the side wall of the central boss of the rotating inner sleeve, ensuring that the one-way rack and the inner ring of the rotating outer sleeve mesh with each other. In this way, the kinetic energy of the rotating outer sleeve can be transferred to the rotating inner sleeve and drive the turntable to rotate. When the rotating inner sleeve continues to rotate under the action of inertia and the rotating outer sleeve stops rotating, the one-way rack moves counterclockwise to disengage from the teeth in the rotating outer sleeve. This allows the rotation to be maintained for a period of time through inertial motion, which is convenient for making pottery. Its principle is similar to the existing bicycle rear wheel axle structure.
[0012] Preferably, the movable cylinder has an overtravel groove on its side, which is used to avoid interference by being offset from the shaft of the drive bevel gear during the downward pressing of the movable cylinder.
[0013] Preferably, a second rotating bracket with a bearing is fixedly provided at the bottom of the workbench, and the drive bevel gear shaft is rotatably disposed in the bearing within the second rotating bracket. In addition, a first rotating bracket is fixedly provided at the bottom of the workbench surface, and a bearing is also provided in the first rotating bracket. The shaft is rotatably disposed in the bearing disposed in the first rotating bracket. The arrangement of the first rotating bracket and the second rotating bracket effectively improves the stability of the transmission shaft.
[0014] The advantages and positive effects of this utility model are:
[0015] By stepping on the movable cylinder, the active bevel gear is driven to rotate in one direction. The active bevel gear drives the rotating shaft to rotate the outer rotating sleeve. During the rotation of the outer rotating sleeve, it in turn drives the inner rotating sleeve to rotate in one direction. After the inner rotating sleeve rotates, it generates inertia and maintains a certain speed, allowing the turntable to make pottery. Compared with the existing technology, it does not require electricity, making it more convenient and energy-saving, with low equipment cost. In addition, it does not require a separate hand to drive the turntable to rotate, freeing up the hand to concentrate more on the pottery making process, reducing the difficulty of operation.

The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:
[0028] like Figure 1-8 As shown, the creative product creation table of this utility model includes:
[0029] A manufacturing table 10 is provided with a rotating outer sleeve 22 in the middle of the manufacturing table 10, and a rotating inner sleeve 23 in the middle of the manufacturing table 10. The bottom of the manufacturing table 10 is provided with a foot pedal driver 16, which converts linear reciprocating motion into rotation and drives the rotating outer sleeve 22 to rotate.
[0030] The outer wall of the rotating inner sleeve 23 is provided with ratchet teeth to disengage from the rotating outer sleeve 22 and transmit unidirectional power through the rotating outer sleeve 22 to the rotating inner sleeve 23, causing the rotating inner sleeve 23 to drive the turntable 21 fixed on the top of the rotating inner sleeve 23 to rotate.
[0031] Preferably, a rotating shaft 12 is coaxially fixed at the bottom of the rotating outer sleeve 22, a driven bevel gear 13 is coaxially fixed at the lower end of the rotating shaft 12, and a driving bevel gear 14 is coaxially fixed at the shaft end of the output shaft of the pedal-type driver 16, and the driving bevel gear 14 and the driven bevel gear 13 mesh.
[0032] Preferably, the pedal-type actuator 16 includes a fixed cylinder 18 and a movable cylinder 17 that slides vertically within the fixed cylinder 18. A return spring 25 is provided within the fixed cylinder 18 to push the one-way rack 24 fixed to the top wall of the movable cylinder 17 upwards, allowing it to return to its original position. A first turntable 26 is rotatably mounted within the fixed cylinder 18. A first ratchet 27 is hinged to the side of the first turntable 26 via a first pivot 29. A limiting post 28 is fixedly mounted on the first turntable 26, restricting the first ratchet 27 from moving upwards. A rotating shaft 29 rotates counterclockwise as the center of rotation. When the one-way rack 24 moves from top to bottom, it can drive the first turntable 26 to rotate through tooth meshing. When the one-way rack 24 returns to its original position, the first ratchet 27 rotates clockwise around the first rotating shaft 29, causing the teeth to misalign and preventing the first turntable 26 from reversing. Furthermore, a pulling protrusion 30 is fixedly provided on the first turntable 26. A spring is connected between the pulling protrusion 30 and the first ratchet 27. The K value of the spring is less than the force required to drive the first turntable 26.
[0033] Preferably, the inner wall of the rotating outer sleeve 22 is provided with a ring array of fixed teeth, and a one-way rack 24 is hinged to the outer countersunk position of the rotating inner sleeve 23 by a return spring 25. When the rotating outer sleeve 22 rotates clockwise, the rotating outer sleeve 22 and the one-way rack 24 mesh with each other. A first turntable 26 is fixedly provided on the one-way rack 24 and abuts against the side wall of the central boss of the rotating inner sleeve 23 so that the one-way rack 24... Figure 8 In this state, it cannot rotate clockwise, ensuring that the teeth of the one-way rack 24 and the inner ring of the rotating outer sleeve 22 mesh. In this way, the kinetic energy of the rotating outer sleeve 22 can be transferred to the rotating inner sleeve 23 and drive the turntable 21 to rotate. When the rotating inner sleeve 23 continues to rotate under the action of inertia and the rotating outer sleeve 22 stops rotating, the one-way rack 24 will move counterclockwise to disengage from the teeth in the rotating outer sleeve 22. This allows it to maintain rotation for a period of time through inertial motion, which is convenient for making pottery. Its principle is similar to the existing bicycle rear wheel axle structure.
[0034] Preferably, the movable cylinder 17 is provided with an overtravel groove 20 on its side, which is used to avoid interference by being offset from the shaft of the drive bevel gear 14 during the downward pressing of the movable cylinder 17.
[0035] Preferably, a second rotating bracket 15 with a bearing is fixedly provided at the bottom of the workbench 10. The shaft of the drive bevel gear 14 is rotatably disposed in the bearing within the second rotating bracket 15. In addition, a first rotating bracket 11 is fixedly provided at the bottom of the workbench 10. The first rotating bracket 11 is also provided with a bearing. The shaft 12 is rotatably disposed in the bearing disposed in the first rotating bracket 11. The arrangement of the first rotating bracket 11 and the second rotating bracket 15 effectively improves the stability of the transmission shaft.
[0036] In specific implementation: by stepping on the movable cylinder 17, the active bevel gear 14 is driven to rotate in one direction. The active bevel gear 14 drives the rotating shaft 12 to drive the rotating outer sleeve 22 to rotate. During the rotation of the rotating outer sleeve 22, it also drives the rotating inner sleeve 23 to rotate in one direction. After the rotating inner sleeve 23 rotates, it generates inertia and maintains a certain speed, so that the turntable 21 can be used for pottery making. Compared with the existing technology, it does not require electricity, which is more convenient and energy-saving, and the equipment cost is low. In addition, it does not require a separate hand to drive the turntable 21 to rotate, freeing up the hand to concentrate more on pottery making, reducing the difficulty of operation.
[0037] It should be emphasized that the embodiments described in this utility model are illustrative and not limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
