Description

Ratchet wrench swing head structure

This invention is about a swing head structure, and in particular, a swing head structure of a ratchet wrench. Through a plurality of connectors and a pivot mechanism, a double-headed ratchet wrench tool can be assembled, and the swing head function is provided. The wrench can be operated at a specific angle in a special space, and the specific angle can be fixed by a clamping structure, making the operation process smoother.

Taiwan's machinery industry is well developed and highly competitive from research and development to maintenance. When working in various complex mechanical structures, there is often only a narrow space available for operators to work, or there are obstacles near the working position, making it difficult for operators to put the wrench tool on the workpiece to be worked on. The operation can only be performed by changing the grip angle. During the operation, the operating angle needs to be constantly changed, which will consume a huge amount of operation time.

Currently, there are adjustable angle wrench tools on the market that can provide different working angles, allowing operators to perform operations smoothly in different spaces. The Republic of China Patent Publication No. M300591 "Wrench Angle Adjustment Structure" provides an adjustable angle wrench structure. It is described in the patent specification that when the angle needs to be adjusted, only the pressing member needs to be operated to make the latch rod be adjusted. The tool head can be adjusted to any angle relative to the handle by sliding the lever with force, and then disengaging the tooth section of the tool head lug. After confirmation, the locking rod is released, and the locking action is re-produced by the reset element, thereby improving the convenience of operation and allowing adjustment of various angles. However, the locking part of this wrench is easily weakened due to wear, causing the wrench angle to change arbitrarily during actual operation, increasing the trouble of operation.

Furthermore, the Republic of China Patent Publication No. I297633 "Bendable and Fixed Wrench Structure" provides a wrench structure with two bendable parts. It can use the design of two hinge mechanisms to bend the wrench head and the gripping part connected at both ends of the hinge into a suitable shape, and then by rotating the adjustment wheel, the locking part is extended outward, and the locking part of the locking part is against the wrench head or the gripping part. The teeth of the hinge block of the grip are used to fix the adjustment angle between the wrench head and the grip; although the previous patent uses the teeth to engage to fix the angle of the wrench, it has higher requirements on the structure and requires more components to perform the rotational engagement. In addition, the hinge block also needs to be additionally formed with teeth, which increases the number of mechanical components and has disadvantages such as increased structural cost and complicated maintenance.

Therefore, how to provide a structure that can quickly fix the angle of the wrench and 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 fixing during the operation process. This is the direction that the creator is thinking about.

Today, the creator has found that the angle adjustment structure of the above-mentioned existing wrench tools still has many shortcomings when actually used, so he improved it with his rich professional knowledge and many years of practical experience, and developed this creation accordingly.

The main purpose of this invention is to provide a ratchet wrench swing head structure, which is formed by multiple connecting parts.

In order to explain the technical features of this invention in detail, the following embodiments are described with reference to the accompanying drawings, but it is not intended to limit the scope of this invention in any form.

[Example 1]

Please refer to Figures 1 to 3, which are the applications of the first embodiment of the present invention, which is mainly composed of a swing head structure consisting of a first connecting member 1, a second connecting member 2 and a hinge assembly 3. The two ends of the swing head structure are then combined with the ratchet head 41 of the ratchet wrench 4 to form a ratchet wrench 4 with both ends being ratchet heads 41.

In the first embodiment, each end of the first connector 1 has a first wing 11, and a first clamping portion 12 is formed between the two first wings 11. The first clamping portion 12 is located in the middle section of the first connector 1 and extends from an inner plane 13 of the first connector 1. The two first wings 11 are both provided with a first connecting hole 111 that passes through the inner plane 13 and the outer plane 14 of the first connector 1. The first connector 1 has two first connecting holes 111, and a first clamping hole 121 is provided in the first clamping portion 12. The first clamping hole 121 passes through the outer plane 14 on one side of the first connector 1 and the plane 15 of the protruding portion.

The second connector 2 has a second wing 21 at each end, and a second clamping portion 22 is formed between the two second wings 21. The second clamping portion 22 is located in the middle section of the second connector 2 and extends from an inner plane 23 of the second connector 2. The two second wings 21 are each provided with a second connecting hole 211 that passes through the inner plane 23 and the outer plane 24 of the second connector 2. The second connector 2 has two second connecting holes 211, and a second clamping hole 221 is provided in the second clamping portion 22. The second clamping hole 221 passes through the outer plane 24 on one side of the second connector 2 and the plane 25 of the protruding portion.

Furthermore, the first connecting member 1, the second connecting member 2 and the ratchet head 41 or the handle of the ratchet wrench 4 are combined through the hinge assembly 3. The ratchet head 41 and the handle are both formed with a hinge block 43, and a hinge hole 431 is provided in the hinge 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 clamping portion 12 and the second clamping portion 22 are arranged opposite to each other with protruding portions, and two accommodating spaces 5 are formed correspondingly between the two first wings 11 and the two second wings 21, and these two accommodating spaces 5 can be used to accommodate the hinge block 43 of the ratchet head 41 of the ratchet wrench 4.

The hinge assembly 3 includes two hinges 31 and a fixing member 32. In the first embodiment, during assembly, one of the hinges 31 is inserted into the first connecting hole 111 of one of the first wings 11 of the first connecting member 1, the hinge hole 431 of the hinge block 43 of the ratchet head 41, and the second connecting hole 211 of one of the second wings 21 of the second connecting member 2. The other hinge 31 is inserted into the other first wing of the first connecting member 1. The first connecting hole 111 of the ratchet head 41, the connecting hole 431 of the connecting block 43 of the other ratchet head 41 and the second connecting hole 211 of the other second wing 21 of the second connecting member 2, and the fixing member 32 is penetrated through the first clamping hole 121 of the first clamping portion 12 of the first connecting member 1 and the second clamping hole 221 of the second clamping portion 22 of the second connecting member 2, and a gap 6 is formed between the first clamping portion 12 and the second clamping portion 22.

Since the pivot 31 and the fixing member 32 in the first embodiment both use bolts, the first connecting hole 111 and the second connecting hole 211 will form internal threads corresponding to the external threads of the bolts. The internal threads will be formed in the first connecting hole 111 or the second connecting hole 211 according to the direction of the bolt locking. The internal threads are not limited to being set in the first connecting hole 111 or the second connecting hole 211. During the assembly process, the ratchet can be installed by tightening the pivot 31. The head 41 of the bolt and the bolt portion in the middle section can provide the ratchet heads 41 at both ends with a degree of freedom to rotate along the axis of the hinge 31, thereby achieving the function of swinging the head. According to the needs of the working space, the ratchet head 41 can be rotated to a required angle to facilitate the execution of the work; if the ratchet head 41 needs to be replaced with a handle or other tool head, only the hinge 31 needs to be loosened to remove the original ratchet head 41 and replace it with the required tool head or handle.

The first clamping hole 121 or the second clamping hole 221 corresponds to the outer thread of the fixing member 32 and is also formed with an inner thread. The inner thread is also formed in the first clamping hole 121 or the second clamping hole 221 according to the direction of bolt locking. The inner thread is not limited to be set in the first clamping hole 121 or the second clamping hole 221. When the fixing member 32 is not completely locked, the gap 6 between the first clamping portion 12 and the second clamping portion 22 is larger, 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 hinge block 43 of the ratchet head 41, so that the ratchet head 41 The angle change action can still be performed. As the fixing member 32 is locked, the first connecting member 1 and the second connecting member 2 will lean against each other, which means that the gap 6 between the first clamping portion 12 and the second clamping portion 22 will gradually shrink, and the distance between the two first wings 11 and the two second wings 21 will become shorter and shorter. Finally, the first wing 11 and the second wing 21 will abut against the hinge block 43 of the ratchet head 41 to achieve a clamping effect. At this time, the ratchet head 41 can no longer rotate, so that the specific angle adjusted by the ratchet wrench 4 can be fixed, avoiding the danger caused by the random rotation of the ratchet head 41 during the operation.

A hinge hole 431 will be provided on the hinge block 43. The second embodiment will be assembled with a ratchet head 41 and a handle member 42. In the second embodiment, the first connecting member 1, the second connecting member 2 and the third connecting member 7 are designed to be integrally formed. The first connecting member 1 and the second connecting member 2 are symmetrically arranged. The first clamping portion 12 of the first connecting member 1 is also arranged opposite to the second clamping portion 22 of the second connecting member 2 with a protruding portion and a gap 6 is formed. A corresponding accommodation space 5 is 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 hinge block 43 of the ratchet head 41 of the ratchet wrench 4. At the other end, a hinge space 44 is formed between the two hinge blocks 43 of the handle member 42 connected to the third connecting member 7 to accommodate the third connecting member 7.

The hinge assembly 3 includes two hinges 31 and a fixing member 32. In the second embodiment, when assembled, one hinge 31 is inserted into the first connecting hole 111 of the first wing 11 of the first connecting member 1, the hinge hole 431 of the hinge block 43 of the ratchet head 41, and the second connecting hole 211 of the second wing 21 of the second connecting member 2. The hinge hole 431 of one hinge block 43 of the handle member 42, the third connecting hole 71 of the third connecting member 7 and the hinge hole 431 of another hinge block 43 of the handle member 42 are provided, and the fixing member 32 is passed through the first clamping hole 121 of the first clamping portion 12 of the first connecting member 1 and the second clamping hole 221 of the second clamping portion 22 of the second connecting member 2.

Since the pivot member 31 and the fixing member 32 both use bolts in the second embodiment, the first connecting hole 111 and the second connecting hole 211 will be formed with internal threads corresponding to the external threads of the bolts. The internal threads will be formed in the first connecting hole 111 or the second connecting hole 211 according to the direction of bolt locking. The internal threads are not limited to be set in the first connecting hole 111 or the second connecting hole 211. The handle member 42 also forms the internal threads in one of the pivot holes 431 according to the direction of bolt locking. The third connecting hole 71 is not provided with internal threads. During the assembly process, By tightening the hinge 31, the ratchet head 41 and the handle 42 can be installed, and the bolt portion in the middle section of the bolt can provide the ratchet head 41 or the handle 42 with a degree of freedom to rotate along the axis of the hinge 31, thereby achieving the function of swinging the head. According to the needs of the working space, the ratchet head 41 or the handle 42 can be rotated to a required angle to facilitate the execution of the work; if the ratchet head 41 or the handle 42 needs to be replaced with other tool heads, only the hinge 31 needs to be loosened to remove the original ratchet head 41 or the handle 42 and replace it with the required tool head.

The first clamping hole 121 or the second clamping hole 221 corresponds to the outer thread of the fixing member 32 and is also formed with an inner thread. The inner thread is also formed in the first clamping hole 121 or the second clamping hole 221 according to the direction of bolt locking. The inner thread is not limited to be set in the first clamping hole 121 or the second clamping hole 221.

As the fixing member 32 is locked, the first connecting member 1 and the second connecting member 2 will lean against each other, which means that the gap 6 between the first pressing portion 12 and the second pressing portion 22 will gradually shrink, and the distance between the first wing portion 11 and the second wing portion 21 will become shorter and shorter. Finally, the first wing portion 11 and the second wing portion 21 will abut against the hinge block 43 of the ratchet head 41 to achieve a clamping effect. At this time, the ratchet head 41 can no longer rotate, so that the specific angle adjusted by the ratchet wrench 4 can be fixed, avoiding the danger caused by the random rotation of the ratchet head 41 during the operation.

Embodiments 1 and 2 of the present invention mainly achieve the effect of fixing the angle by completely 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 be fixed at a specific angle by completely tightening the pivot member 31, and then the fixing member 32 can be tightened to strengthen the fixing force. However, the present invention is not limited to using bolts as the pivot member 31, and a general pin can also be used as the pivot member 31 to provide the purpose of installing and rotating the ratchet head 41 or the handle member 42.
