Technical Field

[0001] The utility model relates to the field of hardware tools, and particularly relates to a lubrication structure for a double-open-ended wrench. Background Technique

[0002] In industrial fields such as mechanical maintenance and vehicle maintenance, the double-open-ended wrench, as a commonly used tool, is widely used in the disassembly and installation processes of fasteners such as bolts and nuts. However, in actual use, due to the resistance generated by metal friction, it is often necessary to lubricate the openings of the double-open-ended wrench to reduce wear and improve work efficiency. The traditional lubrication method usually uses an independent lubrication device or an application tool to directly apply lubricating oil to the openings of the double-open-ended wrench. However, this method has many inconveniences, such as the need to carry an additional lubrication device, uneven application, and the problem of easily soiling the hands.

[0003] To solve the above problems, some lubrication structures integrated on tools have emerged on the market. However, most of these structures are complex in design, high in cost, and not suitable for tools with special shapes and usage requirements such as double-open-ended wrenches. Therefore, it is particularly important to develop a lubrication structure with a simple structure, convenient operation, and suitable for double-open-ended wrenches. Content of the Utility Model

[0004] The purpose of the utility model is to provide a lubrication structure for a double-open-ended wrench to solve the problems raised in the above background technique.

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-11 This utility model provides a technical solution: a lubrication structure for a double open-end wrench, including a storage box 3, which is inserted into a storage groove 2. The storage groove 2 is formed on the surface of the double open-end wrench 1. A reserved hole 4 is formed on the surface of the storage box 3, and a screw groove 5 is formed on the bottom surface of the storage groove 2. After the storage box 3 is inserted into the storage groove 2, a connecting screw 6 is inserted into the reserved hole 4, and the bottom end of the connecting screw 6 is screwed into the screw groove 5. After the storage box 3 is pushed into the storage groove 2, it is fixed in the storage groove 2 by screwing the connecting screw 6 into the screw groove 5.

[0027] An oil storage groove 7 is formed on the surface of the storage box 3. Lubricating oil is contained inside the oil storage groove 7. A sealing piece 8 is fixed at the notch of the oil storage groove 7. An oil injection hole 9 is formed on the surface of the sealing piece 8. The storage box 3 is in the shape of a square cylinder, and the oil storage groove 7 is in the shape of a "匚" - shaped groove. The length of the long side of the oil storage groove 7 is less than that of the long side of the storage box 3. The sealing piece 8 is in the shape of a "匚" - shaped plate structure. A rubber plug block 10 is fixed inside the oil injection hole 9. Oil leakage holes 11 are formed on the inner wall of the storage box 3. The oil leakage holes 11 are communicated with the oil storage groove 7. Absorbent cotton blocks 12 are fixed on both side walls of the storage box 3 that are distributed in parallel. The absorbent cotton blocks 12 cover the oil leakage holes 11. A plug rod 13 is inserted into the storage box 3. An absorbent cotton cover 14 is sleeved and fixed on the rod body of the plug rod 13. After the plug rod 13 is inserted into the storage box 3, the absorbent cotton block 12 and the absorbent cotton cover 14 come into contact. One end of the plug rod 13 is fixed with a dialing block 15. The dialing block 15 is in the shape of an "L" - shaped plate structure. After sucking the lubricating oil with a syringe, the needle penetrates through the oil injection hole 9, and then the lubricating oil is injected into the oil storage groove 7. The lubricating oil soaks the absorbent cotton block 12 through the oil leakage holes 11. When the absorbent cotton cover 14 is inserted into the storage box 3, the absorbent cotton block 12 transfers the lubricating oil with saturated adsorption to the surface of the absorbent cotton cover 14. After pinching the dialing block 15 to draw out the absorbent cotton cover 14 from the storage box 3, the lubricating oil on the surface of the absorbent cotton cover 14 is smeared on the two openings of the double - opening wrench 1 to achieve the lubrication effect. In this way, the lubrication structure is embedded in the wrench of the double - opening wrench 1, and there is no need to specially prepare other lubrication structures.

[0028] A notch 16 is formed on the surface of the double - opening wrench 1. The notch 16 is communicated with the storage groove 2. One end of the storage groove 2 is fixed with a rubber sealing piece 17. One end of the rubber sealing piece 17 is fixed with a magic male sticker 18. After the rubber sealing piece 17 is unfolded, it blocks the storage groove 2. The magic male sticker 18 is connected to a magic female sticker 19 in a matching manner. The magic female sticker 19 is fixed on the surface of the notch 16. When the absorbent cotton cover 14 is inserted into the storage box 3, the rubber sealing piece 17 is unfolded to block the notch of the storage groove 2, and the magic male sticker 18 and the magic female sticker 19 are connected in a matching manner to limit the rubber sealing piece 17.

[0029] The usage process of the lubrication structure for the double - opening wrench is as follows:

[0030] Align the storage box 3 with the opening of the storage slot 2 and push it in smoothly until fully inserted. Insert the connecting screw 6 through the pre-drilled hole 4, ensuring its bottom end is securely screwed into the screw groove 5 to fix the storage box 3. Use a syringe to draw an appropriate amount of lubricating oil. Penetrate the rubber stopper 10 with the needle and inject the lubricating oil into the oil reservoir 7 through the oil injection hole 9. The lubricating oil gradually permeates and wets the oil-absorbing cotton block 12 through the seepage hole 11. Wait for a period of time to ensure that the oil-absorbing cotton block 12 is fully absorbed and saturated with lubricating oil. Align the insert rod 13 and its oil-absorbing cotton cover 14 with the opening of the storage box 3 and insert it. The oil-absorbing cotton cover 14 contacts the oil-absorbing cotton block 12, absorbing excess lubricating oil from its surface. Squeeze the lever 15 (which has an "L"-shaped plate structure) and gently pull the oil-absorbing cotton cover 14 out of the storage box 3. Apply the lubricating oil adhering to the surface of the oil-absorbing cotton cover 14 evenly to the two openings of the double-opening wrench 1. When in use, or when not using the lubrication mechanism, unfold the rubber seal 17 from one end of the storage slot 2 to seal the opening of the storage slot 2. Connect the male Velcro strap 18 to the female Velcro strap 19 fixed to the surface of the notch 16 to ensure the rubber seal 17 securely seals the storage slot 2. After use, reverse the above steps to reinsert the oil-absorbing cotton cover 14 and the insert 13 into the storage box 3 and close the rubber seal 17. Ensure all parts are in a dry and clean environment for future use.
