Technical Field

[0001] The present application relates to the field of tool technology, and in particular to a wrench. Background Art

[0022] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0023] Please refer to Figure 1 , Figure 1 A structure schematic diagram of one specific embodiment of the wrench provided by the present application.

[0024] The present embodiment provides a wrench, comprising:

[0025] The sleeve part 1 is internally hollow, and the axial first end of the sleeve part 1 is an open end.

[0026] The wrench part 2 is connected to the axial first end of the sleeve part 1, and the axial projection of the wrench part 2 is located within the axial projection of the first end. The wrench part 2 at least partially protrudes from the axial first end of the sleeve part 1 in the axial direction, and the wrench part 2 and the axial first end of the sleeve part 1 have a hollow hole that communicates the inside of the sleeve part 1 with the outside.

[0027] The working process of the wrench of the embodiment is as follows:

[0028] The operator holds the sleeve part 1 and directs the axial first end of the sleeve part 1 towards the sealing structure of the liquid container. Since the wrench part 2 at least partially protrudes from the axial first end of the sleeve part 1 in the axial direction, the part of the wrench part 2 protruding from the axial first end of the sleeve part 1 can be connected to the sealing structure. For example, the sealing structure has a cross-shaped slot, and the end of the wrench part 2 away from the sleeve part 1 has a cross-shaped cutter. The operator can insert the cross-shaped cutter structure of the wrench part 2 into the cross-shaped slot of the sealing structure to achieve the circumferential limiting of the sealing structure and the wrench part 2, and then rotate the sleeve part 1 to detach the sealing structure. Since the axial projection of the wrench part 2 is located within the axial projection of the first end, the cross-sectional area of the axial first end of the sleeve part 1 can be designed to be smaller than the cross-sectional area of the open end of the liquid container, so that the open end of the liquid container is also located within the contour range of the axial first end of the sleeve part 1. In this way, after the sealing structure is detached, the liquid in the liquid container can flow into the inside of the sleeve part 1 through the hollow hole between the wrench part 2 and the sleeve part 1, that is, the sleeve part 1 can collect the liquid to reduce the liquid leakage, avoid the liquid pollution of the wrench and the operation space as much as possible, avoid the liquid pollution of the operator's hands as much as possible, improve the operation convenience, and meet the requirement of the positive lower disassembly.

[0029] Please continue to refer to Figure 1 In the embodiment, the sleeve part 1 includes an axial connecting drainage part 11 and a holding part 12. The drainage part 11 is closer to the axial first end of the sleeve part 1 than the holding part 12, and the wrench part 2 is connected to the drainage part 11.

[0030] As described above, the drainage part 11 in the sleeve part 1 can guide the liquid in the liquid container to flow into the inside of the sleeve part 1 to reduce the liquid leakage. The holding part 12 is used for the operator to hold, so that the operator can apply force to the wrench part 2, improve the operation convenience, and improve the work efficiency.

[0031] From Figure 1 As can be seen, in the embodiment, the cross-sectional area of the drainage part 11 decreases in the direction close to the holding part 12.

[0032] In other words, in this embodiment, the drainage portion 11 has a funnel structure, and the large end of the drainage portion 11 is the first end, where the large end of the drainage portion 11 is the end with a larger cross-sectional area. During operation, the large end of the drainage portion 11 faces the sealing structure of the liquid container, so that the liquid inside the liquid container can enter the inside of the sleeve portion 1 through the large end of the drainage portion 11 as much as possible, reducing liquid leakage as much as possible, avoiding liquid pollution of the wrench and the operation space as much as possible, avoiding liquid pollution of the operator's hands as much as possible, and improving the operation convenience.

[0033] At the same time, the small end of the drainage portion 11 is connected to the holding portion 12, and the cross-sectional area of the holding portion 12 is smaller, so that the operator can hold the holding portion 12 more stably, facilitating the operator to apply force to the wrench, improving the operation convenience, and improving the work efficiency.

[0034] In some other embodiments of the present application, the cross-sectional area of the drainage portion 11 is constant along the axial direction of the sleeve portion 1.

[0035] In other words, in this embodiment, the drainage portion 11 has a cylindrical structure, and the cross-sectional area of the drainage portion 11 is designed to be smaller than the cross-sectional area of the open end of the liquid container. The drainage portion 11 can also play a drainage role to guide the liquid inside the liquid container into the inside of the sleeve portion 1, reducing liquid leakage.

[0036] At the same time, the cross-sectional area of the holding portion 12 is set to be smaller than the cross-sectional area of the drainage portion 11, so that the operator can still hold the holding portion 12 stably, facilitating the operator to apply force to the wrench portion 2, improving the operation convenience, and improving the work efficiency.

[0037] By Figure 1 It can be seen that, in this embodiment, the cross section of the sleeve portion 1 has a circular structure.

[0038] In practice, the shape of the sleeve portion 1 is not limited, such as in some other embodiments of the present application, the cross section of the sleeve portion 1 can be square, etc.

[0039] By Figure 1 It can be seen that, in this embodiment, the outer periphery of the holding portion 12 has an anti-slip structure 12a.

[0040] The setting of the anti-slip structure 12a as above can increase the friction when the operator grips the holding portion 12, has an anti-slip effect, improves the stability when the operator grips the holding portion 12, facilitates the operator to apply force to the sleeve portion 1 to realize reliable disassembly of the sealing structure.

[0041] The specific structure of the anti-slip structure 12a is not limited, and in this embodiment, the anti-slip structure 12a is an anti-slip texture provided on the outer periphery of the holding portion 12, which can not only have an anti-slip effect, but also improve the texture of the wrench.

[0042] In some other embodiments of the present application, the anti-skid structure 12a can be a protruding part uniformly distributed on the outer periphery of the holding part 12, such as a round dot protruding part, which not only has an anti-skid effect, but also makes the operator more comfortable when holding the holding part 12.

[0043] Further, in the present embodiment, the wrench part 2 and the sleeve part 1 are detachably connected.

[0044] As arranged above, the operator can replace different wrench parts 2 according to the disassembly needs, such as replacing the wrench part 2 with a one-slot knife when the to-be-disassembled plugging structure has a one-slot, replacing the wrench part 2 with a cross-slot knife when the to-be-disassembled plugging structure has a cross-slot, replacing the wrench part 2 with a six-prism structure when the to-be-disassembled plugging structure has a six-prism slot, and replacing the wrench part 2 with an internal hexagonal sleeve structure when the to-be-disassembled plugging structure is a hexagonal screw, so as to meet the disassembly needs of the corresponding plugging structure.

[0045] As can be seen, the wrench arranged as a detachable structure of the wrench part 2 and the sleeve part 1 in the present embodiment can meet the disassembly needs of different to-be-disassembled structures, and increase the application range of the wrench in the present embodiment.

[0046] In which, the wrench part 2 and the sleeve part 1 are detachably connected, and can have various implementation manners, such as in one implementation manner, the wrench part 2 is internally provided with a wrench connecting part, the peripheral wall of the wrench connecting part has external threads, the wrench part 2 has a matching threaded connecting hole, the wrench connecting part is inserted into the threaded connecting hole and is screwed and fixed, so as to realize the connection of the wrench part 2 and the sleeve part 1, which is not only reliable in connection, but also convenient for disassembly.

[0047] In another implementation manner, the sleeve part 1 is internally provided with a wrench connecting hole, the cross section of the wrench connecting hole can be a triangular, quadrilateral, pentagonal or other structure, the end of the wrench part 2 close to the sleeve part 1 can be a matching triangular prism, quadrangular prism, pentagonal prism or other structure, the end of the wrench part 2 close to the sleeve part 1 is inserted into the inside of the wrench connecting hole, the wrench part 2 and the wrench connecting hole are interference fit, so as to realize the detachable connection of the wrench part 2 and the sleeve part 1.

[0048] Further, in the present embodiment, the cross-sectional area of the wrench part 2 is greater than the minimum area of the hollow hole.

[0049] As arranged above, the wrench part 2 is prevented from falling into the inside of the sleeve part 1 from the hollow hole, so as to avoid the problem that the wrench part 2 falls into the inside of the sleeve part 1 from the hollow hole and cannot be taken out.

[0050] Please continue to refer to Figure 1 In the present embodiment, the wrench further comprises:

[0051] The connecting rod 31 is connected to the inner wall of the sleeve part 1 at both ends of the extension direction of the connecting rod 31, and a hollow hole is formed between the connecting rod 31 and the sleeve part 1. The wrench part 2 is connected to the connecting rod 31.

[0052] Thus, in this embodiment, the connecting rod 31 provides a connection point for the wrench part 2, facilitating the connection of the wrench part 2 to the sleeve part 1. Meanwhile, the hollow hole formed between the connecting rod 31 and the sleeve part 1 facilitates the entry of the liquid inside the liquid container into the inside of the sleeve part 1.

[0053] By Figure 1 As can be seen, this embodiment includes two connecting rods 31, and the wrench part 2 is connected to the intersection of the two connecting rods 31, thereby enhancing the connection strength of the sleeve part 1 and the wrench part 2 and ensuring the connection reliability of the wrench part 2.

[0054] Further, in some embodiments of the present application, the axial second end of the sleeve part 1 is a closed end.

[0055] Thus, during operation, the liquid entering the inside of the sleeve part 1 is temporarily stored in the inside of the sleeve part 1, and then the liquid in the inside of the sleeve part 1 is poured out after the plugging structure is disassembled.

[0056] In some other embodiments of the present application, the axial second end of the sleeve part 1 is an open end.

[0057] Thus, during operation, the axial second end of the sleeve part 1 can be in communication with the liquid collection container, and the liquid entering the inside of the sleeve part 1 from the first end of the sleeve part 1 can directly flow into the inside of the liquid collection container from the second end of the sleeve part 1.

[0058] Therefore, when the axial second end of the sleeve part 1 is a closed end, it is suitable for scenarios where the wrench cannot be directly connected to the liquid collection container. When the axial second end of the sleeve part 1 is an open end, it is suitable for scenarios where the wrench can be directly connected to the liquid collection container, thereby eliminating the subsequent step of pouring out the liquid in the inside of the sleeve part 1.

[0059] Further, when the axial second end of the sleeve part 1 is an open end, the wrench of the present embodiment further includes:

[0060] The adapter part is connected at one end to the axial second end of the sleeve part 1, and the other end of the adapter part is used to connect the liquid collection container.

[0061] Thus, the adapter part serves to connect the sleeve part 1 and the liquid collection container, so that the liquid in the inside of the sleeve part 1 can enter the inside of the liquid collection container, thereby minimizing liquid leakage, avoiding liquid pollution of the wrench and the operation space as much as possible, avoiding liquid pollution of the hands of the operator as much as possible, and improving the operation convenience.

[0062] In some embodiments of the present application, the adapter can be a connecting hose, and the deformable nature of the connecting hose can avoid interference with the operation of the wrench and improve the operational convenience of the wrench.

[0063] In some embodiments of the present application, the adapter and the sleeve portion 1 can be detachably connected, for example, by screwing the adapter and the sleeve portion 1 together. When operating, the adapter and the sleeve portion 1 are connected to facilitate the liquid inside the sleeve portion 1 to enter the liquid collection container. After the operation is completed, the adapter and the sleeve portion 1 are detached to facilitate the storage of the wrench.

[0064] In some other embodiments of the present application, the adapter can also be omitted. The liquid collection container is placed directly below the to-be-detached plugging structure, and the axial second end of the sleeve portion 1 faces the liquid collection container. In this way, the liquid inside the sleeve portion 1 can directly enter the liquid collection container, thereby reducing the leakage of the liquid.
