Description

Technical Field

[0001] This utility model relates to the field of spiral structure technology, and in particular to a press-spinning structure. Background Technology

[0002] In existing patents, the applicant filed a Chinese patent application on March 31, 2023, with application number 202320703708.8, which disclosed a lipstick pen. Specifically, the application disclosed a lifting component including a pusher and a rubber stopper. The pusher is located in an annular tube and pushes the rubber stopper to move from the lower opening towards the upper opening. The pusher includes a bottom cover, a button, a ratchet, a spring, a screw, and a threaded rod. The threaded rod is fixedly located in the inner cavity of the annular tube, and the screw is threaded to the threaded rod. One end of the screw is fixedly connected to the rubber stopper, and the other end of the screw is axially and radially fixedly connected to the ratchet. The bottom cover is fixedly connected to the annular tube and abuts against the ratchet to limit its movement. The button is slidably connected to the bottom cover and used to lift the ratchet. The two ends of the spring are respectively connected to the ratchet and the threaded rod. The ratchet has a lower ratchet tooth, the bottom cover has an outer ratchet tooth, and the button has an inner ratchet tooth. The outer ratchet tooth engages with the lower ratchet tooth, and the inner ratchet tooth engages with the lower ratchet tooth. The external ratchet of the lifting component in this patent document is exposed outside the top of the bottom cover, making it easy to damage. Furthermore, the bottom cover cannot guide or limit the lifting and lowering of the ratchet, making it difficult to improve the lifting and lowering stability of the ratchet. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a press-and-screw structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A press-and-lift structure includes a sleeve, a press-top sleeve, a rotating sleeve, an elastic element, and a lifting screw. A one-way ratchet ring and a support ring are disposed in the middle of the inner wall of the sleeve, with the support ring located below the one-way ratchet ring. A guide ring is disposed on the top side wall of the press-top sleeve, with its bottom surface abutting against the top surface of the support ring. The guide ring is slidably mounted on the inner wall of the one-way ratchet ring. The bottom of the press-top sleeve extends beyond the bottom end of the sleeve. The rotating sleeve is movably disposed within the sleeve and located above the one-way ratchet ring. A ring-shaped saw is disposed on the top surface of the guide ring. The rotating sleeve has at least one abutting block on its peripheral wall. The bottom end of the abutting block has an abutting slope for abutting against the tooth surface of the annular serrated surface or the one-way ratchet ring. The lifting screw passes through the inner hole of the rotating sleeve. The side wall of the lifting screw is recessed with a lifting guide groove that extends along the axis of the lifting screw. The inner wall of the rotating sleeve has a protruding guide block that extends into the lifting guide groove. An elastic element is used to apply elastic force to the rotating sleeve toward the one-way ratchet ring or / and the annular serrated surface. The thread of the lifting screw passes through the external structure.

[0006] Furthermore, the inner wall of the one-way ratchet ring is slidably connected to the guide ring via a sliding structure.

[0007] Furthermore, the sliding structure includes a groove and a slider. The groove is recessed in the inner wall of the one-way ratchet ring and / or the peripheral wall of the guide ring. Correspondingly, the slider protrudes from the peripheral wall of the guide ring and / or the inner wall of the one-way ratchet ring.

[0008] Furthermore, the elastic element is a spring, and a positioning sleeve is provided on the top of the rotating sleeve. The positioning sleeve is arranged around the lifting screw, and one end of the spring is sleeved outside the positioning sleeve.

[0009] Furthermore, a press button is detachably connected to the bottom of the press top sleeve.

[0010] The beneficial effects of this utility model are as follows: In practical applications, the sleeve is fixed to the external structure, and the external structure abuts against the end of the elastic element away from the rotating sleeve. Initially, the elastic force of the elastic element causes the abutting inclined surface of the rotating sleeve's abutting block to press against the tooth surface and annular serrated surface of the one-way ratchet ring. The bottom surface of the guide ring abuts against the top surface of the support ring to limit the pressing top sleeve and prevent loosening between the rotating sleeve, the pressing top sleeve, and the sleeve. When it is necessary to raise the lifting screw, a pressing force is applied to the bottom of the pressing top sleeve, causing the guide ring of the pressing top sleeve to slide upward along the inner wall of the one-way ratchet ring. As the guide ring of the pressing top sleeve slides upward, the annular serrated surface of the guide ring abuts against the abutting inclined surface, causing the rotating sleeve to slide upward along the inner wall of the sleeve and compress the elastic element. When the pressing top sleeve needs to be raised, the pressing force is applied to the bottom of the pressing top sleeve, causing the guide ring of the pressing top sleeve to slide upward along the inner wall of the one-way ratchet ring to compress the elastic element. When the contact slope of the sliding rotating sleeve's contact block is higher than a single ratchet of the one-way ratchet ring, under the elastic force of the elastic element, the contact slope will slide along the slope of the annular serrated surface on the guide ring to the slope of the next ratchet of the one-way ratchet ring. This causes the contact slope to slide relative to the slope of the ratchet of the one-way ratchet ring, thereby causing the rotating sleeve to drive the lifting screw to rotate synchronously by a preset angle. During the rotation of the rotating sleeve and the lifting screw, since the lifting screw is screwed to the external structure, with the cooperation of the guide block and the lifting guide groove, the lifting screw can follow the rotating sleeve to rotate by a preset angle and also rise relative to the rotating sleeve by a preset height. Each time the top sleeve is pressed, the lifting screw rises by a preset height (a fixed amount of height). This invention achieves a press-type lifting mechanism. The one-way ratchet ring is located inside the sleeve, which protects the one-way ratchet ring, strengthens its strength, prevents it from being exposed and easily damaged, and extends its service life. Furthermore, the sleeve guides and limits the lifting of the rotating sleeve, improving its working stability. Attached Figure Description

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figures 1 to 4 As shown, this utility model provides a press-and-lift structure, which includes a sleeve 1, a pressing top sleeve 2, a rotating sleeve 3, an elastic element 4, and a lifting screw 5. A one-way ratchet ring 6 and a support ring 7 are provided in the middle of the inner wall of the sleeve 1. The support ring 7 is located below the one-way ratchet ring 6. A guide ring 8 is provided on the top side wall of the pressing top sleeve 2. The bottom surface of the guide ring 8 is used to abut against the top surface of the support ring 7. The guide ring 8 is slidably mounted on the inner wall of the one-way ratchet ring 6. The bottom of the pressing top sleeve 2 extends beyond the bottom end of the sleeve 1. The rotating sleeve 3 is movably mounted inside the sleeve 1 and located above the one-way ratchet ring 6. The top surface of the guide ring 8 is provided with an annular serrated surface 9. The peripheral wall of the sleeve 3 is provided with at least one abutting block 10. The bottom end of the abutting block 10 is provided with an abutting inclined surface 11. The abutting inclined surface 11 is used to abut against the tooth surface of the annular serrated surface 9 or the one-way ratchet ring 6. The lifting screw 5 passes through the inner hole of the rotating sleeve 3. The side wall of the lifting screw 5 is recessed with a lifting guide groove 12. The lifting guide groove 12 extends along the axis of the lifting screw 5. The inner wall of the rotating sleeve 3 is provided with a guide block 13. The guide block 13 extends into the lifting guide groove 12. The elastic element 4 is used to apply elastic force to the rotating sleeve 3 toward the one-way ratchet ring 6 and / or the annular serrated surface 9. The lifting screw 5 is threaded through the external structure. The rotating sleeve 3 can rotate and rise and fall within the sleeve 1.

[0019] In practical applications, sleeve 1 is fixed to the external structure, and the external structure abuts against the end of elastic element 4 away from rotating sleeve 3. Initially, the elastic force of elastic element 4 causes the abutting inclined surface 11 of the abutting block 10 of rotating sleeve 3 to press against the tooth surface and annular serrated surface 9 of one-way ratchet ring 6. The bottom surface of guide ring 8 abuts against the top surface of support ring 7 to limit the pressing top sleeve 2 and prevent loosening between rotating sleeve 3, pressing top sleeve 2 and sleeve 1. When it is necessary to raise the lifting screw 5, a pressing force is applied to the bottom of pressing top sleeve 2, causing the guide ring 8 of pressing top sleeve 2 to slide upward along the inner wall of one-way ratchet ring 6. As the guide ring 8 of pressing top sleeve 2 slides upward, the annular serrated surface 9 of guide ring 8 abuts against the abutting inclined surface 11, causing rotating sleeve 3 to slide upward along the inner wall of sleeve 1 and compress elastic element 4. When the contacting inclined surface 11 of the contacting block 10 of the rotating sleeve 3 is higher than a single ratchet of the one-way ratchet ring 6, under the elastic force of the elastic element 4, the contacting inclined surface 11 will slide along the inclined surface of the annular serrated surface 9 on the guide ring 8 to the inclined surface of the next ratchet of the one-way ratchet ring 6, so that the contacting inclined surface 11 slides relative to the inclined surface of the ratchet of the one-way ratchet ring 6, thereby causing the rotating sleeve 3 to drive the lifting screw 5 to rotate synchronously by a preset angle. During the rotation of the rotating sleeve 3 and the lifting screw 5, since the lifting screw 5 is screwed to the external structure, with the cooperation of the guide block 13 and the lifting guide groove 12, the lifting screw 5 can follow the rotating sleeve 3 to rotate by a preset angle, and can also rise to a preset height relative to the rotating sleeve 3. Each time the top sleeve 2 is pressed, the lifting screw 5 will rise to a preset height (a fixed height). This utility model realizes a press-type lifting mechanism. The one-way ratchet ring 6 is located inside the sleeve 1. The sleeve 1 protects the one-way ratchet ring 6, strengthens its strength, prevents it from being exposed and easily damaged, and extends its service life. In addition, the sleeve 1 guides and limits the lifting of the rotating sleeve 3, improving the working stability of the rotating sleeve 3.

[0020] In this embodiment, the inner wall of the one-way ratchet ring 6 is slidably connected to the guide ring 8 via a sliding structure. Specifically, the sliding structure includes a groove 14 and a slider 15. The groove 14 is recessed in the inner wall of the one-way ratchet ring 6 and / or the peripheral wall of the guide ring 8, and correspondingly, the slider 15 protrudes from the peripheral wall of the guide ring 8 and / or the inner wall of the one-way ratchet ring 6. By setting up the sliding structure, and preventing the guide ring 8 from rotating relative to the one-way ratchet ring 6, the guide ring 8 can only slide up and down, thus improving the stability of the sliding of the guide ring 8 relative to the inner wall of the one-way ratchet ring 6.

[0021] In this embodiment, the elastic element 4 is a spring. A positioning sleeve 16 is provided on the top of the rotating sleeve 3. The positioning sleeve 16 is arranged around the lifting screw 5. The bottom end of the spring is sleeved outside the positioning sleeve 16 and the spring is sleeved outside the lifting screw 5. The bottom end of the spring extends into the sleeve 1. This structural design facilitates the assembly of the elastic element 4, guides and positions the elastic element 4, and improves the working stability of the elastic element 4.

[0022] In this embodiment, a pressing button 17 is detachably connected to the bottom of the pressing top sleeve 2. The addition of the pressing button 17 extends the length of the pressing top sleeve 2, making it easier to press the pressing top sleeve 2.

[0023] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
