Vertical ratchet tool structure

Abstract

A vertical ratchet tool structure includes a brake seat, a brake assembly, a rotating shaft, and all controls. The inner ring wall of the brake chamber is staggered with two symmetrical stops, a first stop, and a second stop. The first stop and the second stop are asymmetrically offset by an angle, and the two stops and the first and second stops define four braking spaces for the installation of the brake assembly. By utilizing the offset angle design of the first and second stops of the brake seat, there is a half-tooth difference between the two symmetrical geared parts, so that they can be engaged with the ratchet at a selected instant. This helps to improve the actuation accuracy of the geared parts, thereby achieving the purpose of fast engagement drive at a small angle. It also has the advantages of convenient storage, portability, and lightweight use.

Description

Technical Field

[0001] This invention relates to a ratchet tool, and more particularly to a vertical ratchet tool structure that features bidirectional rapid gear engagement and lightweight design. Prior Technology

[0002] The prior art discloses a screwdriver with a ratchet mechanism. This screwdriver uses a ratchet and a toothed component to transmit torque. When in use, rotating in one direction facilitates tightening or loosening of the part by twisting it. When rotating in the opposite direction, the toothed component and the ratchet are in a free-spinning disengagement state, so that the drive end of the screwdriver does not need to leave the part. The hand and handle can be returned to an angle that facilitates twisting force without stopping, so as to quickly tighten or loosen the part.

[0003] However, in commonly used ratchet tools, all the teeth on the surface of the gear are designed with equal angles and engage with the ratchet teeth. When the gear engages with the ratchet again after idling, the teeth of the gear must pass over the ratchet teeth to make a proper bite connection. This causes friction between the gear teeth and the ratchet teeth, which can easily lead to damage. Furthermore, if the gear teeth do not make a proper bite connection at the beginning, they must pass through at least one more tooth's distance to make them mesh again. This causes a noticeable step jump during the tool's rotation and increases the collision force between the teeth. This not only affects the stability of the operation but also significantly reduces the service life of the gear teeth, making them impractical.

[0004] In view of this, based on the inventor's many years of experience in manufacturing, developing and designing related products, and after detailed design and careful evaluation for the above objectives, the inventor has finally obtained an invention that is truly practical.

[0027] To enable your review committee to have a better understanding of the purpose, features, and effects of this invention, the following is a detailed description in conjunction with the accompanying drawings:

[0028] First, please refer to Figures 1, 2, and 3 in conjunction with Figures 4 and 5 to observe a vertical ratchet tool structure, which includes: a brake seat 10, a brake assembly 20, a rotating shaft 30, and all controls 40. One end of the brake seat 10 has an axially arranged brake chamber 11, and the other end of the brake seat 10 has a protruding assembly 12 for assembling a handle 13. The inner ring wall of the brake chamber 11 has two symmetrically protruding stops 14, a first stop 15, and a second stop 16. The first stop 15... 5 and the second abutment 16 are asymmetrically offset by an angle A, and the two stops 14 and the first and second abutments 15 and 16 define four braking spaces 17. The inner ring wall of the braking chamber 11 is provided with a first positioning groove 111, a second positioning groove 112 and a third positioning groove 113 at equal intervals. The braking assembly 20 includes four toothed members 21 and four elastic members 22. Each toothed member 21 is fitted with an elastic member 22 at one end and is respectively disposed in the four braking spaces 17. One end of the elastic member 22 abuts against the stop 14. The end edge, and simultaneously pushes the toothed parts 21 toward the first and second locking portions 15 and 16 respectively, and each of the toothed parts 21 has a toothed portion 211; the rotating shaft 30 includes a shaft portion 31 and a ratchet 32 ​​formed on the outer diameter of the shaft portion 31, the outer peripheral surface of the ratchet 32 ​​is provided with a plurality of ratchet teeth 321, and the ratchet 32 ​​is assembled into the braking chamber 11, with the ratchet teeth 321 facing the toothed portion 211 of the toothed parts 21, and one end of the shaft portion 31 is provided with a non-circular tool hole 311; the cutting control 40 is A central shaft hole 41 is provided at both ends through the axial direction. The rotating shaft 30 passes through the central shaft hole 41 and is then assembled into the braking chamber 11. A first blocking block 42 and a second blocking block 43 are protruded from one end surface of the cutting control 40 corresponding to the positions of the first and second locking parts 15 and 16. A through hole 44 is provided on the outer diameter of the cutting control 40 to accommodate an elastic element 45 and a positioning element 46. The positioning element 46 is pushed outward by the elastic element 45 and positioned in one of the first, second, and third positioning grooves 111, 112, and 113.

[0029] Further explanation: the inner wall of the brake chamber 11 has a through groove 121 axially penetrating the assembly 12. The rotating shaft 30 has a shaft portion 31 and a central shaft post 312 with a diameter smaller than that of the shaft portion 31. The central shaft post 312 is adjacent to the ratchet 32. The central shaft post 312 is then assembled into the through groove 121, and the ratchet 32 ​​abuts against the inner wall and is confined within the annular space formed by the two stops 14 and the first and second locking portions 15 and 16. The outer diameter of the central shaft post 312 has a first annular groove 313 that extends beyond the assembly 12. Finally, it is connected to the first annular groove via a C-shaped buckle 314. The groove 313 is fastened to achieve the combined positioning of the rotating shaft 30; the cutting control 40 has a large diameter section 401 and a small diameter section 402. The large diameter section 401 is assembled into the braking chamber 11 and abuts against the side walls of the stop 14 and the first and second locking parts 15 and 16. The through hole 44 is provided on the outer diameter surface of the large diameter section 401 to provide the elastic member 45 and the positioning member 46 for setting. The rotating shaft 30 is provided with a second annular groove 315, which is matched with a C-shaped buckle 316. The C-shaped buckle 316 is used to rotatably restrict the cutting control 40 on the rotating shaft 30.

[0030] Further explanation can be seen from Figures 2 and 4. Both the first abutment portion 15 and the second abutment portion 16 of the brake seat 10 have two abutment surfaces 151 and 161 at their ends, and a central surface 152 and 162 are formed between these two abutment surfaces 151 and 161. These central surfaces 152 and 162 are not planar but concave arc-shaped. One end of each toothed member 21 is provided with a contact portion 212, which abuts against the abutment surfaces 151 and 161. Furthermore, the position of the center surface 152 of the first abutment portion 15 and the position of the center surface 162 of the second abutment portion 16 are not located on the same straight line as the diameter of the brake seat 10. They have a deviation angle A of at least 3 degrees, so that the toothed members 21 that abut against the first abutment portion 15 and the second abutment portion 16 have a distance of half a tooth difference, so that the toothed portions 211 of the two toothed members 21 located in symmetrical positions will not simultaneously engage and disengage the ratchet teeth 321 of the ratchet 32.

[0031] The actual usage state of its structure can be viewed by referring to Figures 1 and 3 in conjunction with Figures 4, 5, and 6. The first blocking block 42 and the second blocking block 43 of the cutting control 40 are respectively aligned with the first locking part 15 and the second locking part 16, so that the positions of the first and second blocking blocks 42 and 43 are not located on the same straight line of the diameter of the large diameter section 401, and the two also have a deviation angle of at least 3 degrees. Accordingly, when the positioning member 46 of the cutting control 40 is engaged and positioned with the second positioning groove 112 of the brake seat 10, the... The first blocking block 42 is positioned opposite to the center surface 152 of the first locking portion 15, and the second blocking block 43 is positioned opposite to the center surface 162 of the second locking portion 16. This ensures that all geared components 21 are not obstructed by the first and second blocking blocks 42 and 43, and that the locking surface 151 of the first locking portion 15 or the locking surface 161 of the second locking portion 16 can engage the geared components 21 with the ratchet teeth 321 of the ratchet 32, allowing the brake seat 10 to rotate clockwise or counterclockwise to drive the geared components 21. The rotating shaft 30 rotates without idling; further explained, due to the design of the deviation angle A of the first and second locking parts 15 and 16, the two geared parts 21 located at the upper position in Figure 6 are engaged with the ratchet 32, while the two geared parts 21 located at the lower position are disengaged from the ratchet 32 ​​due to a half-tooth distance. When the brake seat 10 rotates clockwise, the geared part 21 located at the upper position in Figure 6 and in the clockwise direction will be abutted by the locking surface 151 of the first locking part 15 in the clockwise direction and engage with the ratchet. 32, thereby driving the rotating shaft 30 to rotate clockwise. When the brake seat 10 rotates counterclockwise, the toothed member 21 located at the upper position in Figure 6 and in the counterclockwise direction will also be abutted by the counterclockwise abutment surface 151 of the first abutment part 15 and engage with the ratchet 32, thereby driving the rotating shaft 30 to rotate counterclockwise. Conversely, when the two toothed members 21 at the lower position are engaged with the ratchet 32, the two toothed members 21 at the upper position will also be disengaged from the ratchet 32 ​​due to a half-tooth distance (not shown in the figure).

[0032] When the cutting control 40 rotates counterclockwise and is engaged with the first positioning groove 111 of the brake seat 10 by the positioning member 46, as shown in Figures 1 and 3 in conjunction with Figures 7 and 8, the first and second blocking blocks 42 and 43 of the cutting control 40 rotate counterclockwise and move toward the locking surfaces 151 and 161 of the first and second locking portions 15 and 16 in the counterclockwise direction, thereby pushing the two gear members 21 located in the first and second locking portions 15 and 16 in the counterclockwise direction to retract counterclockwise (located on the diagonal). The two geared components 21 within the braking space 17 are positioned such that their contact portions 212 are moved away from the counterclockwise contact surfaces 151 and 161 of the first and second contact portions 15 and 16. Due to the design of the deviation angle A of the first and second contact portions 15 and 16, the geared component 21 located at the upper clockwise position in Figure 8 is engaged with the ratchet 32, while the geared component 21 located at the lower clockwise position is disengaged from the ratchet 32 ​​due to a half-tooth distance. At this time, when the brake seat 10 rotates clockwise... In Figure 8, the clockwise gear 21 at the top is abutted against and engaged with the ratchet 32 ​​by the clockwise abutment surface 151 of the first abutment portion 15, thereby driving the rotating shaft 30 to rotate clockwise. Conversely, when the brake seat 10 rotates counterclockwise, as shown in Figure 9, because the two counterclockwise gears 21 are far away from the counterclockwise abutment surfaces 151 and 161 of the first and second abutment portions 15 and 16, neither gear 21 can engage with the ratchet teeth 321 of the ratchet 32, thus forming a reverse rotation. When the clockwise rotation is in the idle state, when the brake seat 10 is rotated clockwise again, due to the half-tooth difference design of the two geared parts 21 in the clockwise direction, there is a half-tooth difference between the two geared parts 21, so that they can be engaged with the ratchet teeth of the ratchet 32 ​​at a certain moment, as shown in Figure 10. The lower geared part 21 in the clockwise direction is abutted by the clockwise abutting surface 161 of the second abutting part 16 and engages with the ratchet 32, while the geared part 21 in the upper clockwise position is disengaged from the ratchet 32 ​​due to the half-tooth distance.

[0033] Furthermore, when the cutting control 40 rotates clockwise and is engaged with the third positioning groove 113 of the brake seat 10 by the positioning member 46, as shown in Figures 11 and 12, the first and second blocking blocks 42 and 43 of the cutting control 40 rotate clockwise and displace towards the clockwise locking surfaces 151 and 161 of the first and second locking portions 15 and 16, respectively, thereby pushing the first and second locking portions 15 and 16 clockwise. The two geared components 21 are retracted clockwise (the two geared components 21 located in the two diagonally opposite braking spaces 17), and the contact portion 212 of the two geared components 21 is moved away from the clockwise contact surfaces 151 and 161 of the first and second contact portions 15 and 16. Due to the design of the deviation angle A of the first and second contact portions 15 and 16, the geared component 21 located in the upper counterclockwise position in Figure 11 is in a geared state with the ratchet 32, and The toothed component 21 located in the lower counterclockwise position is disengaged from the ratchet 32 ​​due to a half-tooth distance. When the brake seat 10 rotates counterclockwise, the toothed component 21 in the upper counterclockwise direction (Figure 11) is abutted against and engages with the ratchet 32 ​​by the counterclockwise abutment surface 151 of the first abutment portion 15, thereby driving the rotating shaft 30 to rotate counterclockwise. Conversely, when the brake seat 10 rotates clockwise, the toothed component 21 in the clockwise direction... The clockwise abutment surfaces 151 and 161 of the first and second abutment portions 15 and 16 are moved away from each other, so that neither of the two geared parts 21 can engage with the ratchet teeth 321 of the ratchet 32, thus forming a clockwise free-spinning state. When the brake seat 10 is rotated counterclockwise again, due to the half-tooth difference design of the two geared parts 21 in the counterclockwise direction, the gap between the two geared parts 21 is only half a tooth difference, so that they can engage with the ratchet teeth of the ratchet 32 ​​at a certain moment.

[0034] By utilizing the structure of the above specific embodiment, the following benefits can be obtained: The present invention utilizes the deviation angle A of the first locking part 15 and the second locking part 16 of the brake seat 10 to make the two symmetrical toothed parts 21 have a half-tooth difference, so that they can be selected to form a geared driving state with the ratchet 32 ​​at an instant. This helps to improve the operating accuracy of the toothed parts 21, thereby achieving the purpose of small-angle fast geared driving, and greatly reducing the wear and collision of the teeth, which helps to improve the service life of the ratchet tool.

[0035] Secondly, the braking space 17 is sequentially formed on the inner annular wall of the brake seat 10, and the toothed member 21 and the elastic member 22 are disposed in the braking space 17. The ratchet 32 ​​of the rotating shaft 30 is centrally inserted into the braking chamber 11, and the ratchet teeth 321 of the ratchet 32 ​​face the toothed part 211 of the toothed member 21, so that the rotating shaft 30 and the brake seat 10 form a coaxial engagement state, which helps to reduce the overall volume of the tool and achieve the effects of convenient storage, carrying and lightweight use.

[0036] In conclusion, this invention has indeed achieved a breakthrough in structural design and possesses improved inventive content. At the same time, it can achieve industrial applicability and progress. Furthermore, this invention has not been published in any publication and also possesses novelty. Therefore, it meets the relevant provisions of the Patent Law. Thus, we have filed an invention patent application in accordance with the law and earnestly request the Examining Committee of the Bureau to grant legal patent rights. We are deeply grateful.

[0037] The above description is merely one preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention; that is, all equivalent changes and modifications made in accordance with the claims of the present invention should still fall within the scope of the present invention.
