Description

Technical Field

[0001] This utility model belongs to the field of wrench technology, and in particular relates to a multi-angle bendable wrench. Background Technology

[0002] Currently, the most commonly used wrenches for loosening and tightening bolts and nuts in confined spaces are short-handled open-end wrenches. Although they are more flexible than conventional wrenches, relying entirely on the movement of the arm and various joints to operate them in complex and confined spaces can easily lead to injuries. For example, an airplane is a highly integrated machine with numerous mechanisms such as mechanical transmission systems, hydraulic transmission systems, electrical systems, and power systems designed within the limited space on board. Due to space constraints, compromises in maintenance space are inevitably made during the design phase. Therefore, using a short-handled open-end wrench requires the arm to move back and forth between mechanical parts in a complex and confined space, which is not only difficult to operate but also very likely to cause arm cuts.

[0003] Therefore, there is an urgent need to design a multi-angle bendable wrench to solve the problem mentioned above of the difficulty in disassembling and tightening bolts and nuts in confined spaces, which can easily cause arm cuts. Utility Model Content

[0004] To address the technical problem mentioned in the background art of difficulty in disassembling and tightening bolts and nuts in confined spaces, a multi-angle bendable wrench is provided to solve the above problem.

[0005] To achieve the above objectives, the specific technical solution of this utility model's multi-angle bendable wrench is as follows:

[0006] A multi-angle bendable wrench includes a wrench head, a first bending member on the wrench head, the first bending member controlling the rotation of the wrench head in a first rotation direction, a second bending member on the first bending member, the second bending member controlling the rotation of the first bending member in a second rotation direction, and a handle on the end of the second bending member away from the first bending member.

[0007] Furthermore, the first rotation direction and the second rotation direction are perpendicular to each other.

[0008] Furthermore, the first bending member includes a first housing and a first rotating shaft. The first rotating shaft is mounted on the first housing, and the wrench head is rotatably connected to the first bending member through the first rotating shaft. The first housing is provided with a second bending member.

[0009] Furthermore, the second bending member includes a second outer shell and a second rotating shaft. The second rotating shaft is mounted on the second outer shell, and the first outer shell is rotatably connected to the second bending member through the second rotating shaft. The second outer shell is provided with a handle.

[0010] Furthermore, it also includes a first connecting rod, one end of which is fixedly connected to the first housing, and the other end of which is rotatably connected to the second rotating shaft.

[0011] Furthermore, the first connecting rod is a telescopic rod.

[0012] Furthermore, it also includes a second connecting rod, one end of which is fixedly connected to the second housing, and the other end of which is fixedly connected to the handle.

[0013] Furthermore, the first bending member is provided with a first locking structure to lock the angle of the wrench head; the second bending member is provided with a second locking structure to lock the angle of the second bending member.

[0014] Furthermore, the first bending member includes a first housing and a first rotating shaft. The first rotating shaft is installed inside the first housing. The wrench head is rotatably connected to the first bending member through the first rotating shaft. A second bending member is provided on the first housing. A first locking structure is located on the first housing. The first locking structure is provided with a first locking tongue. The first locking structure includes a locked state and an active state.

[0015] When the first locking structure is in the locked state, the first locking tongue is fixed in contact with the wrench head, restricting the movement of the wrench head.

[0016] When the first locking structure is in the active state, the first locking tongue separates from the wrench head, allowing the wrench head to rotate around the first pivot.

[0017] Furthermore, the first locking structure includes a horizontal push rod, and the first housing has a first hole and a second hole, which are perpendicular to each other. The horizontal push rod matches the first hole and is connected to the first hole by a first spring. The second hole matches the first latch, and the first latch is connected to the second hole by a second spring. The horizontal push rod has a receiving groove on its body.

[0018] When the first locking structure is in the locked state, the first spring is in the free state, the second spring is in the compressed state, one end of the first locking tongue abuts against the body of the horizontal push rod, and the end of the first locking tongue away from the horizontal push rod abuts against the wrench head.

[0019] When the first locking structure is in the active state, the second spring is in the free state, the first spring is in the compressed state, and the first locking tongue is engaged with the receiving groove of the horizontal push rod.

[0020] The multi-angle bendable wrench of this utility model has the following advantages:

[0021] This utility model achieves angle adjustment through the first bending member and the second bending member, and length adjustment through the first connecting rod and the second connecting rod.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0030] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This utility model describes a multi-angle bendable wrench.

[0031] Currently available tools for loosening and tightening bolts and nuts in confined spaces are short-handled open-end wrenches. While these are more flexible than conventional wrenches, they rely entirely on the movement of the arm joints to avoid the complex piping and mechanical components within such spaces. This back-and-forth movement of the arm among these intricate parts greatly increases the risk of arm injuries, posing a significant safety hazard to maintenance personnel in their daily work.

[0032] Therefore, this utility model provides a multi-angle bendable wrench, such as... Figure 1 and Figure 2 As shown, the device includes a wrench head 1, with a first bending member 2 on the wrench head 1. The first bending member 2 controls the rotation of the wrench head 1 in a first rotation direction A. The first bending member 2 has a second bending member 3, which controls the rotation of the first bending member 2 in a second rotation direction B. A handle 4 is provided at the end of the second bending member 3 away from the first bending member 2. Specifically, the operator can control the wrench head 1 to rotate in the first rotation direction A through the first bending member 2, and then control the first bending member 2 to rotate in the second rotation direction B through the second bending member 3, thereby changing the angle of the wrench head 1. This allows the wrench head 1 to adapt to the installation and removal of bolts and nuts at different angles and orientations. For example, the operator can control the wrench head 1 to rotate horizontally through the first bending member 2, thus changing the angle of the wrench head 1 in the horizontal direction. The operator can then control the first bending member 2 to rotate vertically through the second bending member 3, thus changing the angle of the wrench head 1 in the vertical direction. The angle of the wrench head can be fixed according to actual needs, allowing the operator to choose a convenient operating space in confined spaces to install and remove bolts and nuts, thereby avoiding injury.

[0033] Preferably, the wrench head 1 is configured as a replaceable structure to accommodate bolts and nuts of different sizes. Optionally, in one specific embodiment, the wrench head 1 includes a square tenon and an open wrench head. The open wrench head has a square tenon that matches the square tenon. The square tenon and the square tenon cooperate to realize the detachable structure of the wrench head 1. Multiple open wrenches are provided to cooperate with the square tenon, thereby allowing the wrench head 1 to accommodate bolts and nuts of different sizes. Optionally, the wrench head 1 is made of chrome vanadium steel to ensure its robustness and durability.

[0034] Preferably, the first rotation direction A and the second rotation direction B are perpendicular to each other, thereby ensuring that the angle adjustment range of the wrench head 1 is maximized.

[0035] Preferably, the first bending member 2 includes a first housing 201 and a first rotating shaft 202. The first rotating shaft 202 is mounted on the first housing 201, and the wrench head 1 is rotatably connected to the first bending member 2 via the first rotating shaft 202. A second bending member 3 is provided on the first housing 201. Specifically, the first rotating shaft 202 is mounted on the first housing 201, and the wrench head 1 is rotatably connected to the first rotating shaft 202, achieving a compact structure between the first bending member 2 and the wrench head 1 while allowing the wrench head 1 to rotate around the first rotating shaft 202.

[0036] Preferably, the second bending member 3 includes a second outer shell 301 and a second rotating shaft 302. The second rotating shaft 302 is mounted on the second outer shell 301, and the first outer shell 201 is rotatably connected to the second bending member 3 via the second rotating shaft 302. A handle 4 is provided on the second outer shell 301. Specifically, the second rotating shaft 302 is mounted on the second outer shell 301, and the first outer shell 201 is rotatably connected to the second bending member 3 via the second rotating shaft 302. This achieves structural compactness between the second bending member 3 and the first bending member 2 while allowing the first bending member 2 to rotate around the second rotating shaft 302. Furthermore, the handle 4 on the second outer shell 301 facilitates operation by the operator.

[0037] Preferably, in one specific embodiment, the multi-angle bendable wrench provided by this utility model further includes a first connecting rod 5. One end of the first connecting rod 5 is fixedly connected to the first housing 201, and the end of the first connecting rod 5 away from the first housing 201 is rotatably connected to the second rotating shaft 302. Specifically, by connecting the first bending member 2 and the second bending member 3 through the first connecting rod 5, it is further convenient for the operator to insert the device into a narrow, slit-like space and install or remove bolts and nuts.

[0038] Preferably, the first connecting rod 5 is a telescopic rod. Optionally, in a specific embodiment, the first connecting rod 5 has a built-in threaded sleeve, and a screw is screwed onto the threaded sleeve. By manually rotating the screw, the first connecting rod 5 can be extended or shortened to the required length to adapt to different working conditions. The thread on the screw and the threaded sleeve are self-locking threads, which self-lock through friction during use.

[0039] As a preferred embodiment, the multi-angle bendable wrench provided by this utility model further includes a second connecting rod 6. One end of the second connecting rod 6 is fixedly connected to the second housing 301, and the end of the second connecting rod 6 away from the second housing 301 is fixedly connected to the handle 4. At the same time, the second connecting rod 6 can be set as a telescopic rod with the same structure as the first connecting rod 5, so as to facilitate the operator to install and remove bolts and nuts in narrow slit-shaped spaces. Furthermore, it is understood that the telescopic adjustment of the first connecting rod 5 and the second connecting rod 6 is not limited to the above structure, and other structures well known to those skilled in the art can also be selected, such as a nested telescopic rod composed of multiple sections of pipes of different diameters nested together.

[0040] As a preferred option, such as Figure 3 and Figure 4 As shown, the first bending member 2 is provided with a first locking structure 7 to lock the angle of the wrench head 1; the second bending member 3 is provided with a second locking structure to lock the angle of the second bending member 3, so that the operator can control the angle of the wrench head 1 through the first locking structure 7 and control the angle of the second bending member 3 through the second locking structure, thereby controlling the angle of the first connecting rod 5, thus avoiding the structure in the narrow space and facilitating personnel operation.

[0041] Preferably, the first locking structure 7 is located on the first outer shell 201. The first locking structure 7 is provided with a first locking tongue 701. The first locking structure 7 includes a locked state and an active state. When the first locking structure 7 is in the locked state, the first locking tongue 701 abuts and fixes against the wrench head 1, restricting the movement of the wrench head 1, thereby fixing the angle of the wrench head 1. When the first locking structure 7 is in the active state, the first locking tongue 701 separates from the wrench head 1, allowing the wrench head 1 to rotate around the first rotating shaft 202, thereby allowing the angle of the wrench head 1 to be readjusted.

[0042] As a preferred option, such as Figure 4As shown, the first locking structure 7 includes a horizontal push rod 702. A first hole 100 and a second hole 200 are provided on the first housing 201. The first hole 100 and the second hole 200 are perpendicular to each other. The horizontal push rod 702 matches the first hole 100 and is connected to the first hole 100 by a first spring 704. The second hole 200 matches the first locking tongue 701 and is connected to the second hole 200 by a second spring 705. The horizontal push rod 702 has... A receiving groove 703 is provided. When the first locking structure 7 is in the locked state, the first spring 704 is in a free state, the second spring 705 is in a compressed state, one end of the first locking tongue 701 abuts against the body of the horizontal push rod 702, and the end of the first locking tongue 701 away from the horizontal push rod 702 abuts against the wrench head 1. When the first locking structure 7 is in the movable state, the second spring 705 is in a free state, the first spring 704 is in a compressed state, and the first locking tongue 701 fits into the receiving groove 703 of the horizontal push rod 702. Specifically, the first locking structure 7 is always in the locked state. After pressing the horizontal push rod 702, the first locking tongue 701 falls into the receiving groove 703, at which time the angle of the wrench head 1 can be adjusted.

[0043] The second locking structure is identical to the first locking structure 7, and is located on the second housing 301 to lock the angle of the second bent member 3.

[0044] The method of using this utility model is as follows: Select an open wrench of appropriate size to assemble the wrench head 1, adjust the angle through the first locking structure 7 and the second locking structure, adjust the length of the first connecting rod 5 and the second connecting rod 6 at the same time, so that they are extended to the required length, and lock the length to adapt to the internal structure in different narrow spaces. Finally, the personnel can perform installation and disassembly operations through the handle 4.

[0045] This utility model achieves angle adjustment through the first bending member 2 and the second bending member 3, while also achieving length adjustment through the first connecting rod 5 and the second connecting rod 6. Furthermore, the wrench head 1 can be quickly disassembled and reassembled as needed.

[0046] This utility model has a stable and reliable structure, and provides operators with a safer and more reliable assembly method by using a tool that can adapt to disassembly and maintenance in confined spaces.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
