Abstract
Description
Technical Field
[0001] The utility model relates to a swing head structure, in particular to a swing head structure of a ratchet wrench. Through a plurality of connecting pieces and a pivoting mechanism, a double-headed ratchet wrench tool can be combined to provide the function of the swing head. In a special space, the wrench can also be operated at a specific angle, and through a tightening structure, a specific angle can be fixed, making the operation process smoother. Background Art
[0002] When operating in various complex mechanical structures, there is often only a narrow space available for the operator to work, or there are obstacles near the working position, making it difficult for the operator to socket the wrench tool onto the workpiece to be operated. Only by changing various holding angles can the operation be performed. During the operation process, constantly changing the operation angle will consume a huge amount of operation time.
[0003] Currently, there are already wrench tools with adjustable angles on the market, which can provide different working angles, enabling the operator to smoothly perform operations in various different spaces; the patent with the publication number TWM300591U (wrench angle adjustment structure) provides a wrench structure with adjustable angles. As disclosed in the patent specification, when angle adjustment is required, only the pressing part needs to be operated to make the locking rod slide under force, and then disengage from the tooth section of the lug of the tool head, so that the tool head can be adjusted arbitrarily relative to the handle rod. After confirmation, release the locking rod, and it will be driven by the reset element to generate a locking effect again, which can enhance the operation convenience and can be adjusted at multiple angles. However, the locking part of this wrench is prone to wear and weaken the fixing effect, causing the wrench angle to change randomly during actual operation, increasing the trouble of operation.
[0004] In addition, the patent with the publication number TWI297633B (wrench structure that can be bent and fixed) provides a wrench structure with two bendable parts. It can utilize the design of two pivoting mechanisms to bend the wrench heads and the holding parts connected to both ends of the pivot piece into appropriate shapes, and then by rotating the adjustment wheel, the clamping piece extends outwards, and the clamping part of the clamping piece abuts against the tooth pattern of the pivot block of the wrench head or the holding part to fix the adjustment angle of the wrench head and the holding part. Although this patent fixes the angle of the wrench in the way of tooth pattern meshing, it has relatively high requirements for the structure, requires more components to perform the rotation and meshing part, and additional tooth patterns need to be formed on the pivot block, increasing the structural components, and having the disadvantages of increased structural cost and complex maintenance.
[0005] Therefore, how to provide a structure that can quickly fix the angle of the wrench and can also provide good fixing force, so that after the wrench is adjusted to a specific angle, the angle will not be easily changed due to unstable fixation during the operation process, which is the direction considered by the inventor. Summary of the Invention

[0056] The present utility model mainly applies a plurality of connecting members and a hinge assembly to a ratchet wrench. A hinge structure is provided on the plurality of connecting members, and then the plurality of connecting members are combined with the ratchet head or the handle member of the ratchet wrench by a hinged shaft member to form a ratchet wrench with a swing head structure.
[0057] In order to explain in detail the technical features of the present utility model, the following embodiments are hereby described in conjunction with the drawings, but it is not intended to limit the scope of the present utility model in any form.
[0058] Embodiment 1
[0059] Please refer toFigures 1 to 3 , which is the application of the first embodiment of the present utility model, mainly consists of a swing head structure composed of a first connecting member 1, a second connecting member 2 and a pivoting assembly 3. The two ends of the swing head structure are combined with the ratchet head 41 of the ratchet wrench 4 to form a ratchet wrench 4 with ratchet heads 41 at both ends.
[0060] In the first embodiment, each end of the first connecting member 1 has a first wing portion 11. A first pressing portion 12 is formed between the two first wing portions 11. The first pressing portion 12 is located in the middle section of the first connecting member 1 and protrudes from an inner plane 13 of the first connecting member 1. Among them, each of the two first wing portions 11 is provided with a first connecting hole 111 that penetrates the inner plane 13 and the outer plane 14 of the first connecting member 1. The first connecting member 1 thus has two first connecting holes 111, and the first pressing portion 12 is provided with a first pressing hole 121 that penetrates the outer plane 14 on one side of the first connecting member 1 and the plane 15 of the protruding portion.
[0061] Each end of the second connecting member 2 has a second wing portion 21. A second pressing portion 22 is formed between the two second wing portions 21. The second pressing portion 22 is located in the middle section of the second connecting member 2 and protrudes from an inner plane 23 of the second connecting member 2. Among them, each of the two second wing portions 21 is provided with a second connecting hole 211 that penetrates the inner plane 23 and the outer plane 24 of the second connecting member 2. The second connecting member 2 thus has two second connecting holes 211, and a second pressing hole 221 is provided on the second pressing portion 22, and the second pressing hole 221 penetrates the outer plane 24 on one side of the second connecting member 2 and the plane 25 of the protruding portion.
[0062] In addition, the first connecting member 1, the second connecting member 2 and the ratchet head 41 or the handle member of the ratchet wrench 4 are combined through the pivoting assembly 3. The ratchet head 41 and the handle member are both formed with a pivoting block 43, and a pivoting hole 431 is provided in the pivoting block 43. The first embodiment will be assembled with two ratchet heads 41; before assembly, the first connecting member 1 and the second connecting member 2 are symmetrically arranged, the first pressing portion 12 and the second pressing portion 22 are arranged with the protruding parts facing each other, and two accommodating spaces 5 are correspondingly formed between the two first wing portions 11 and the two second wing portions 21. These two accommodating spaces 5 can be used to accommodate the pivoting blocks 43 of the ratchet heads 41 of the ratchet wrench 4.
[0063] The pivot assembly 3 includes two pivot members 31 and a fixing member 32. In the first embodiment during assembly, one of the pivot members 31 passes through the first connection hole 111 of one of the first wings 11 of the first connecting member 1, the pivot hole 431 of the pivot block 43 of the ratchet head 41, and the second connection hole 211 of one of the second wings 21 of the second connecting member 2. The other pivot member 31 passes through the first connection hole 111 of the other first wing 11 of the first connecting member 1, the pivot hole 431 of the pivot block 43 of the other ratchet head 41, and the second connection hole 211 of the other second wing 21 of the second connecting member 2. The fixing member 32 passes through the first tightening hole 121 of the first tightening portion 12 of the first connecting member 1 and the second tightening hole 221 of the second tightening portion 22 of the second connecting member 2. At this time, a gap 6 is formed between the first tightening portion 12 and the second tightening portion 22.
[0064] Since the pivot member 31 and the fixing member 32 are both fixed with bolts in the first embodiment, the first connection hole 111 and the second connection hole 211 are formed with internal threads corresponding to the external threads of the bolts. The internal threads are formed in the first connection hole 111 or the second connection hole 211 according to the locking direction of the bolts. There is no limitation that the internal threads must be provided in the first connection hole 111 or the second connection hole 211. During the assembly process, by tightening the pivot member 31, the part of the ratchet head 41 can be installed. Moreover, the bolt portion in the middle of the bolt can provide a degree of freedom of rotation for the ratchet heads 41 at both ends along the axis of the pivot member 31 to achieve the function of swinging the head. According to the needs of the working space, the ratchet head 41 can be rotated to the required angle to facilitate the execution of the operation. If it is necessary to replace the ratchet head 41 with a handle or other tool heads, only by loosening the pivot member 31, the original ratchet head 41 can be removed and replaced with the required tool head or handle.
[0065] The first tightening hole 121 or the second tightening hole 221 is also formed with an internal thread corresponding to the external thread of the fixing member 32. The internal thread is also formed in the first tightening hole 121 or the second tightening hole 221 corresponding to the bolt locking direction. This internal thread is not necessarily set in the first tightening hole 121 or the second tightening hole 221; when the fixing member 32 is not fully tightened, the gap 6 between the first tightening portion 12 and the second tightening portion 22 is relatively large, and the first wing portion 11 of the first connecting member 1 and the second wing portion 21 of the second connecting member 2 do not abut against the pivoting block 43 of the ratchet head 41, allowing the ratchet head 41 to still perform the angle conversion action. As the fixing member 32 is tightened, the first connecting member 1 and the second connecting member 2 will approach each other, indicating that the gap 6 between the first tightening portion 12 and the second tightening portion 22 gradually decreases, and the distance between the two first wing portions 11 and the two second wing portions 21 will also become shorter and shorter. Finally, the first wing portion 11 and the second wing portion 21 abut against the pivoting block 43 of the ratchet head 41 to achieve the clamping effect. At this time, the ratchet head 41 cannot rotate anymore, so that the specific angle adjusted by the ratchet wrench 4 can be fixed, avoiding the risk caused by the random rotation of the ratchet head 41 during the operation.
[0066] Embodiment 2
[0067] Please refer to Figures 4 to 6 , in Embodiment 2 of the present utility model, the first connecting member 1 and the second connecting member 2 are integrally formed, and a third connecting member 7 is further formed. The first connecting member 1, the second connecting member 2 and the third connecting member 7 are combined with the pivoting assembly 3 to form a swing head structure. The swing head structure of Embodiment 2 enables the two ends to be combined with the ratchet head 41 or the handle member 42 of the ratchet wrench 4 in different connection manners to form the ratchet wrench 4.
[0068] In Embodiment 2, one end of the first connecting member 1 has a first wing portion 11, and a first tightening portion 12 is formed at a position adjacent to the first wing portion 11. The first tightening portion 12 is located in the middle section of the first connecting member 1 and protrudes from an inner plane 13 of the first connecting member 1. Among them, the first wing portion 11 is provided with a first connection hole 111 penetrating the inner plane 13 and the outer plane 14 of the first connecting member 1, and a first tightening hole 121 is provided in the first tightening portion 12. The first tightening hole 121 penetrates the outer plane 14 on one side of the first connecting member 1 and the plane 15 of the protruding portion.
[0069] One end of the second connecting member 2 has a second wing portion 21, and a second pressing portion 22 is formed at a position adjacent to the second wing portion 21. The second pressing portion 22 is located in the middle section of the second connecting member 2 and protrudes from an inner plane 23 of the second connecting member 2. Among them, the second wing portion 21 is provided with a second connecting hole 211 that penetrates the inner plane 23 and the outer plane 24 of the second connecting member 2, and a second pressing hole 221 is provided in the second pressing portion 22. The second pressing hole 221 penetrates the outer plane 24 on one side of the second connecting member 2 and the plane 25 of the protruding portion.
[0070] The second embodiment further includes a third connecting member 7, which is formed at one end of the end plane 8 jointly formed by the first connecting member 1 and the second connecting member 2. This end is the other end relative to the first wing portion 11 of the first connecting member 1 and the second wing portion 21 of the second connecting member 2. The third connecting member 7 protrudes from the end plane 8 and is provided with a third connecting hole 71.
[0071] In addition, through the pivot assembly 3, the first connecting member 1, the second connecting member 2, the third connecting member 7 and the ratchet head 41 or the handle member 42 of the ratchet wrench 4 are combined. The ratchet head 41 and the handle member 42 will form one or two pivot blocks 43 according to the combination with the first connecting member 1, the second connecting member 2 or the third connecting member 7. A pivot hole 431 is provided on the pivot block 43. The second embodiment will be assembled with one ratchet head 41 and one handle member 42. In the second embodiment, the first connecting member 1, the second connecting member 2 and the third connecting member 7 are integrally formed. The first connecting member 1 and the second connecting member 2 are symmetrically arranged. The first pressing portion 12 of the first connecting member 1 and the second pressing portion 22 of the second connecting member 2 are oppositely arranged with the protruding parts and form a gap 6. And a receiving space 5 is correspondingly formed between the first wing portion 11 of the first connecting member 1 and the second wing portion 21 of the second connecting member 2 to accommodate the pivot block 43 of the ratchet head 41 of the ratchet wrench 4. At the other end, a pivot space 44 is formed between the two pivot blocks 43 of the handle member 42 connected to the third connecting member 7 to accommodate the third connecting member 7.
[0072] The pivot assembly 3 includes two pivot members 31 and a fixing member 32. When assembling the second embodiment, one of the pivot members 31 passes through the first connecting hole 111 of the first wing portion 11 of the first connecting member 1, the pivot hole 431 of the pivot block 43 of the ratchet head 41 and the second connecting hole 211 of the second wing portion 21 of the second connecting member 2. The other pivot member 31 passes through the pivot hole 431 of one of the pivot blocks 43 of the handle member 42, the third connecting hole 71 of the third connecting member 7 and the pivot hole 431 of the other pivot block 43 of the handle member 42. And the fixing member 32 passes through the first pressing hole 121 of the first pressing portion 12 of the first connecting member 1 and the second pressing hole 221 of the second pressing portion 22 of the second connecting member 2.
[0073] Since the pivot member 31 and the fixing member 32 are both fixed by bolts in the second embodiment, the first connection hole 111 and the second connection hole 211 are formed with internal threads corresponding to the external threads of the bolts. The internal threads are formed in the first connection hole 111 or the second connection hole 211 according to the locking direction of the bolts. There is no limitation that the internal threads must be provided in the first connection hole 111 or the second connection hole 211. The handle member 42 also forms internal threads in one of the pivot holes 431 according to the locking direction of the bolts, and the third connection hole 71 is not provided with internal threads. During the assembly process, by tightening the pivot member 31, the part of the ratchet head 41 and the handle member 42 can be installed. Moreover, the bolt part in the middle section of the bolt can provide a degree of freedom for the ratchet head 41 or the handle member 42 to rotate along the axis of the pivot member 31, achieving the function of swinging the head. According to the needs of the working space, the ratchet head 41 or the handle member 42 can be rotated to the required angle to facilitate the execution of the operation. If it is necessary to replace the ratchet head 41 or the handle member 42 with other tool heads, only by loosening the pivot member 31, the original ratchet head 41 or the handle member 42 can be removed and replaced with the required tool head.
[0074] The first pressing hole 121 or the second pressing hole 221 is also formed with internal threads corresponding to the external threads of the fixing member 32. The internal threads are also formed in the first pressing hole 121 or the second pressing hole 221 according to the locking direction of the bolts. There is no limitation that the internal threads must be provided in the first pressing hole 121 or the second pressing hole 221. When the fixing member 32 is not fully tightened, the gap 6 between the first pressing portion 12 and the second pressing portion 22 is relatively large, and the first wing portion 11 of the first connecting member 1 and the second wing portion 21 of the second connecting member 2 do not abut against the pivot block 43 of the ratchet head 41, so that the ratchet head 41 can still perform the angle-changing action. As the fixing member 32 is tightened, the first connecting member 1 and the second connecting member 2 will approach each other, indicating that the gap 6 between the first pressing portion 12 and the second pressing portion 22 will gradually decrease, and the distance between the first wing portion 11 and the second wing portion 21 will also become shorter and shorter. Finally, the first wing portion 11 and the second wing portion 21 abut against the pivot block 43 of the ratchet head 41, achieving the clamping effect. At this time, the ratchet head 41 cannot rotate anymore, so that the specific angle adjusted by the ratchet wrench 4 can be fixed, avoiding the ratchet head 41 rotating randomly during the operation and causing danger.
[0075] In the first embodiment and the second embodiment of the present invention, the effect of fixing the angle is mainly achieved by fully tightening the fixing member 32. In addition, if a bolt is used as the pivot member 31, the ratchet head 41 or the handle member 42 can also be fixed at a specific angle by fully tightening the pivot member 31, and then the fixing member 32 is tightened to strengthen the fixing force. However, the present invention does not limit the use of a bolt as the pivot member 31. A general pin can also be used as the pivot member 31 to achieve the purpose of installing and rotating the ratchet head 41 or the handle member 42.
[0076] As can be seen from the above implementation description, compared with the prior art, the utility model has the following advantages:
[0077] 1. The swing head structure of the ratchet wrench of the utility model combines a plurality of connecting pieces with a pivot assembly to form a swing head structure, which can fix the ratchet head of the ratchet wrench to the handle part. The pivot part provides an angle-changing action. According to the needs of the working space, the ratchet head or the handle part can be rotated to the required angle, so that the operator can also have an appropriate working angle in a narrow space.
[0078] 2. The swing head structure of the ratchet wrench of the utility model provides a tightening effect on the ratchet head or the handle part of the ratchet wrench through the tightening part on the connecting piece. By completely locking the fixing piece, the gap between the first tightening part and the second tightening part can be reduced, and the first connecting piece and the second connecting piece can be made to approach each other, so as to achieve a tightening effect on the pivot block of the ratchet head or the handle part. Only through a simple structural design and operation method, the specific angle adjusted by the ratchet wrench can be effectively fixed.
[0079] In summary, the swing head structure of the ratchet wrench of the utility model can indeed achieve the expected use effect through the embodiments disclosed above; the above-mentioned description of the drawings and the meanings of the reference numerals are only preferred embodiments of the utility model. The methods and components disclosed in the previous embodiments are only for illustrative purposes and are not used to limit the scope of the utility model.
