Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to an adjustable wrench. Background Technology

[0002] A locking wrench is a commonly used auxiliary tool for installation and disassembly. Currently, most locking wrenches on the market can only be used on the outside of the workpiece to be turned, where there is no obstruction. For threaded parts with internal locking holes in the workpiece, a fixed locking wrench is usually used. A fixed locking wrench has two opposing locking rods fixedly connected to it, which engage with two spaced-apart tightening interfaces on the workpiece to be turned, allowing the operator to rotate the workpiece using the locking wrench. Existing technology has the following drawbacks: the tightening interface spacing varies for workpieces with different hole diameters, requiring a corresponding adapter for each workpiece diameter during operation, resulting in poor compatibility and a large number of tools.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figure 1 and Figure 2 As shown, the adjustable wrench of this utility model embodiment includes a handle 1, two first locking members 2, and a locking member 3. The length of the handle 1 extends along a first direction (the first direction is the X direction shown in the figure). The two first locking members 2 are slidably disposed on the handle 1 along a second direction (the second direction is the Y direction shown in the figure), and the locking member 3 can fix the first locking members 2 to the handle 1. Along the second direction, the ends of the two first locking members 2 that are far apart from each other are respectively provided with locking parts 21. The locking parts 21 are used to lock the workpiece 100 that is rotated. The first direction is perpendicular to the second direction.

[0031] It is understandable that by adjusting the two first locking parts 2 along the second direction, the distance between the two locking parts 21 can be adjusted, thereby enabling the two locking parts 21 to adapt to the locking of workpieces 100 of different sizes to be turned, improving the flexibility and versatility of the adjustable wrench, increasing compatibility, and reducing the situation of numerous tools that are difficult to manage and have high manufacturing costs; with the cooperation of the locking part 3, the position of the first locking part 2 can be adjusted and fixed to the handle 1, preventing the locking part from sliding or loosening during use, and ensuring the stability and reliability of the wrench.

[0032] In this embodiment, as Figure 1 As shown, along the second direction, each of the two first snap-fit ​​parts 2 has a snap-fit ​​portion 21 protruding from its opposite side. The length of the snap-fit ​​portion 21 extends along the first direction, and the snap-fit ​​portion 21 can snap into the slot 101 of the workpiece 100 to be turned. By snapping the snap-fit ​​portion 21 into the slot 101 of the workpiece 100 to be turned, the adjustable wrench is connected to the workpiece 100 to be turned, so that the operator's rotation of the handle 1 can drive the rotation of the workpiece 100 to be turned, thereby realizing the installation or removal of the workpiece 100 to be turned.

[0033] For example, two slots 101 are provided opposite to each other on the inner side wall of the workpiece 100 to be rotated, and the slots 101 penetrate the workpiece 100 to be rotated and form an insertion port on one side along the first direction. According to the model of the workpiece 100 to be rotated, that is, the distance between the two slots 101, the operator adjusts the position of the two first snap-fit ​​parts 2 so that the distance between the two snap-fit ​​parts 21 corresponds to the distance between the two slots 101. The operator then holds an adjustable wrench to align the two snap-fit ​​parts 21 with the two insertion ports and snap them into the two slots 101. Thus, by using the restriction of the snap-fit ​​parts 21 by the slots 101, the operator can rotate the workpiece 100 to be rotated by turning the handle 1. However, in this embodiment, the slot 101 is provided on one side of the workpiece 100 to be rotated along the first direction, and the slot 101 penetrates the inner and outer walls of the workpiece 100 to be rotated. The locking part 21 is inserted into the slot 101 along the opening of the slot 101 and abuts against the bottom of the slot 101. At this time, the handle 1 can be rotated to drive the workpiece 100 to be rotated.

[0034] Preferably, such as Figure 3 As shown, the snap-fit ​​part 21 and the first snap-fit ​​member 2 are provided with a reinforcing rib 25 on the side where the snap-fit ​​part 21 is provided, which is used to improve the structural stability of the snap-fit ​​part 21 and prevent the snap-fit ​​part 21 from twisting or separating from the first snap-fit ​​member 2 during the snap-fit ​​and twisting process.

[0035] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, two first snap-fit ​​members 2 are respectively provided with relief grooves 22 along the first direction near the side of the workpiece 100 to be turned, and the relief grooves 22 penetrate through the side of the first snap-fit ​​member 2 where the snap-fit ​​part 21 is provided. The groove walls of the two relief grooves 22 are spaced apart to form abutment parts, which can snap into the inner side wall of the workpiece 100 to be turned, and the workpiece 100 to be turned can abut against the bottom of the relief groove 22. That is, based on the snap-fit ​​part 21 snapping into the groove 101 on one side of the workpiece 100 to be turned along the first direction, the abutment parts snapping into the inner side wall of the workpiece 100 to be turned improve the connection stability between the adjustable wrench and the workpiece 100 to be turned, prevent the first snap-fit ​​member 2 from sliding or loosening, and improve the safety during use. In addition, the abutment between the workpiece 100 to be turned and the relief groove 22 can also achieve positioning and increase the connection mating surface, thereby further ensuring the stability of the fit between the workpiece 100 to be turned and the adjustable wrench.

[0036] In another embodiment, such as Figure 4 As shown, each of the two first snap-fit ​​members 2 has a snap-fit ​​portion 21 protruding from one side of the workpiece 100 to be turned along the first direction. The snap-fit ​​portion 21 can snap into the positioning hole 102 of the workpiece 100 to be turned. That is, the workpiece 100 to be turned has two positioning holes 102 on one side along the first direction, and the two snap-fit ​​portions 21 snap into the two positioning holes 102 respectively to realize the connection between the adjustable wrench and the workpiece 100 to be turned.

[0037] Of course, in addition to the two forms described above, the two types of snap-fit ​​parts 21 can also be integrated into the same first snap-fit ​​member 2. That is, the snap-fit ​​part 21 includes a first snap-fit ​​part and a second snap-fit ​​part. The first snap-fit ​​part is provided on the side of the first snap-fit ​​member 2 that is far away from each other along the second direction. The first snap-fit ​​part can snap into the slot 101 of the workpiece 100 to be rotated. At the same time, the second snap-fit ​​part is provided on the side of the first snap-fit ​​member 2 that is adjacent to the workpiece 100 to be rotated along the first direction. The second snap-fit ​​part can snap into the positioning hole 102 of the workpiece 100 to be rotated, further improving the compatibility of the workpiece 100 to be rotated.

[0038] In this embodiment, as Figure 1 and Figure 2As shown, a mounting groove 11 is provided through the outer peripheral wall of the handle 1, and the mounting groove 11 is adjacent to the side of the handle 1 adjacent to the workpiece 100 to be rotated along the first direction. Two first locking members 2 are arranged side by side in the mounting groove 11 along a third direction (the third direction is the Z direction shown in the figure). One end of the first locking member 2 with a locking part 21 protrudes from the mounting groove 11. The third direction is perpendicular to the first direction and the second direction, respectively. The groove wall of the mounting groove 11 restricts the first locking members 2, which helps to ensure the connection between the handle 1 and the rotating workpiece during use, reducing the risk of loosening and falling off. The groove wall of the mounting groove 11 provides support for the first locking members 2 to support the rotation of the first locking members 2, reducing stress concentration, making the overall structure more balanced during use, and helping to improve the overall service life and fatigue resistance.

[0039] Furthermore, two opposing first threaded holes 12 are provided on the outer periphery of the handle 1. The length of the first threaded holes 12 extends along a third direction, and the first threaded holes 12 communicate with the mounting groove 11. Each first threaded hole 12 corresponds to a locking member 3 screwed on to abut against a first snap-fit ​​member 2. In this embodiment, the locking member 3 can be directly a bolt. By screwing the bolt through the first threaded hole 12, the first snap-fit ​​member 2 is abutted against the other first snap-fit ​​member 2. The two bolts are locked together to achieve mutual abutment and fixation. The connection method of screwing the bolts together is simple to operate and convenient to disassemble and assemble.

[0040] Of course, in addition to providing the first threaded hole 12 on the outer periphery of the handle 1, two second threaded holes communicating with the mounting groove 11 can also be provided on the side of the handle 1 adjacent to the workpiece 100 to be turned along the first direction. Each second threaded hole corresponds to a first snap-fit ​​2, and each second threaded hole corresponds to a locking member 3 screwed in to abut against a first snap-fit ​​2. In other words, the locking member 3 is a bolt, which passes through the second threaded hole to abut against the groove wall of the mounting groove 11, so as to fix the first snap-fit ​​2 to the handle 1. In addition, in addition to bolts, the locking member 3 can also be a headless screw to reduce the impact of the exposed bolt head on the turning of the workpiece.

[0041] Furthermore, the first snap-fit ​​component 2 is provided with a limiting groove 23, the length of which extends along the second direction. The locking component 3 is slidably connected to the limiting groove 23, and the locking component 3 can abut against the bottom of the limiting groove 23. By setting the limiting groove 23, on the one hand, the cooperation between the groove wall of the limiting groove 23 and the locking component 3 can enhance the connection stability between the first snap-fit ​​component 2 and the locking component 3. On the other hand, the limiting groove 23 can be used to restrict the movement and adjustment of the first snap-fit ​​component 2. That is, when adjustment is required, the locking component 3 can be loosened, but the locking component 3 is still located in the limiting groove 23. The length of the limiting groove 23 limits the adjustment range of the first snap-fit ​​component 2, preventing the first snap-fit ​​component 2 from disengaging from the mounting groove 11 and improving the adjustment convenience of the first snap-fit ​​component 2.

[0042] Optionally, a guide portion is provided on one side of the two adjacent first snap-fit ​​blocks, and a guide groove 24 is provided on the other side. The length of the guide groove 24 extends along the second direction, and the guide portion and the guide groove 24 are slidably connected. The cooperation between the guide portion and the guide groove 24 can further improve the stability of the engagement and the guiding of movement between the two first snap-fit ​​blocks 2, and reduce the shaking or positional displacement between the two first snap-fit ​​blocks 2.

[0043] In other embodiments, the adjustable wrench further includes a second locking member. At least one second locking member is slidably disposed on the outer periphery of the handle 1. The sliding direction of the second locking member is set at an angle to the sliding direction of the first locking member 2. The second locking member can engage with the workpiece 100 to be rotated. In other words, the workpiece 100 to be rotated not only has two locking points for the first locking member 2 to engage, but also has locking points for the second locking member to engage. By engaging the second locking member with the workpiece 100 to be rotated, the number of engagement points between the adjustable wrench and the workpiece 100 to be rotated can be further increased, the engagement stability between the adjustable wrench and the workpiece 100 to be rotated can be increased, and the possibility of concentrated force on the adjustable wrench can be reduced.

[0044] Optionally, such as Figure 1 and Figure 2 As shown, the adjustable wrench also includes a handle 4, which is detachably connected to the end of the handle 1 away from the workpiece 100 to be turned along the first direction. The detachable design of the handle 4 allows the operator to flexibly adjust the length of the handle 4 according to actual needs, providing a larger and more convenient operating space. For example, a through hole 13 is provided through the outer periphery of the handle 1, and the handle 4 can be inserted into the through hole 13.

[0045] In addition to being detachably connected to the handle 1, the handle 4 can also be rotatably connected to at least one other handle 4 on the outer periphery of the handle 1, with the handle 4 adjacent to the end of the handle 1 away from the workpiece 100 to be turned along the first direction. The handle 4 can be rotated perpendicularly or parallel to the length direction of the handle 1. The rotatable connection between the handle 4 and the handle 1 facilitates the folding and storage of the handle 4, making it easy to store and carry, reducing space occupation. Operators can also adjust the operating angle of the handle 4 according to actual needs to meet the usage requirements under different working conditions, ensuring the flexibility of the adjustable wrench in different working environments.

[0046] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
