DETAILED DESCRIPTION

[0024] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0025] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself; "first" and "second" are used to distinguish one element from another and do not have sequentiality or importance. In addition, the same figure marks in different reference drawings represent the same elements.

[0026] The present disclosure provides a lubricating tool for a screw, referring to Figures 1 to 5 As shown, the lubrication tool includes a first sleeve 1 and a lubricating member 2, wherein the first sleeve 1 has a first end and a second end opposite to each other along its length direction, the first end has a first opening 101 for inserting a screw, and a receiving cavity 102 for accommodating the screw is formed in the first sleeve 1; the lubricating member 2 is connected to the inner wall of the receiving cavity 102, and the lubricating member 2 is configured to be able to adhere to grease and to be able to fit against the outer wall of the screw when the screw is inserted into the receiving cavity 102, so as to apply grease to the screw.

[0027] Through the above technical solution, that is, the lubricating tool for a screw provided by the present disclosure, when grease is applied to the surface of a screw (for example, a screw of a wind turbine) by the lubricating tool to lubricate the screw, the grease can be poured into the accommodating chamber 102 through the first opening 101. The grease can be temporarily stored in the accommodating chamber 102 and is not easy to spill out. When the grease is evenly in contact with the lubricating part 2 in the accommodating chamber 102, the screw to be lubricated can be inserted into the accommodating chamber 102 from the first opening 101. At this time, the lubricating part 2 can be attached to the outer wall of the screw so that the screw can be lubricated with grease, and the first sleeve 1 or the screw can be rotated so that the first sleeve 1 and the screw can rotate relative to each other, thereby allowing the grease to be more evenly covered on the outer periphery of the screw, thereby reducing the difficulty of application. Moreover, by inserting the screw into the first sleeve 1 so as to evenly contact the grease in the accommodating chamber 102, the grease is not easy to spill out of the accommodating chamber 102, and the waste of grease can be reduced.

[0028] It should be noted that the lubricating part 2 mentioned in the above embodiment can be any part that can adhere to grease and lubricate the surface of the screw. For example, the lubricating part 2 can be a brush, an oil roller, or a hole body through which grease can flow out. The present disclosure will elaborate on the lubricating part in detail below, so no further details will be given here.

[0029] In some embodiments, reference Figures 1 to 5 As shown, there are multiple lubricating parts 2, and the multiple lubricating parts 2 are arranged at intervals along the circumference and depth direction of the inner wall of the accommodating cavity 102. In this way, when the screw is inserted into the accommodating cavity 102 and rotates relative to the first sleeve 1, the multiple lubricating parts 2 can simultaneously adhere to the outer wall of the screw and lubricate the outer surface of the screw through the attached grease, thereby improving the lubrication efficiency of the screw.

[0030] In some embodiments, reference Figure 3 and Figure 4 As shown, the lubricating member 2 is constructed as a brush. In this way, when the screw is inserted into the accommodating cavity 102 of the first sleeve 1, the surface of the screw can be lubricated by the grease-attached brush. The bristles of the brush are relatively soft, and even the blind spots and gaps in the external thread area of ​​the screw surface can be lubricated in place, thereby improving the full coverage of the lubrication of the screw surface. In addition, the brush mentioned in the above embodiment can also be selected according to the diameter of the screw to select different lengths of brushes to adapt to screws of different diameters, thereby improving the versatility of the lubrication tool.

[0031] In addition, the length of the first sleeve 1 and the depth of the accommodating chamber 102 extending along the length direction of the first sleeve 1 can also be selected as any appropriate value according to the length of the screw. It is only necessary to ensure that the outer surface of the screw can be evenly lubricated when the screw is inserted into the accommodating chamber 102. For example, when the length of the screw is 1m, the depth of the accommodating chamber 102 can be designed to be greater than 0.5m and less than 1m. In this way, when lubricating the 1m screw, the accommodating chamber 102 with a length of less than 1m can ensure that there is a margin for the staff to manually pull out the screw when it is fully inserted. And the length is designed to be greater than 0.5m, and the entire screw can also be lubricated. That is, when one end of the screw is inserted into the accommodating chamber 102 and lubricated, the screw can be pulled out and the other end of the screw can be inserted into the accommodating chamber 102 again to lubricate the remaining unlubricated part.

[0032] In some embodiments, reference Figures 1 to 5 As shown, the lubricating tool further includes a second sleeve 3, which is sleeved on the first sleeve 1 and has a second opening 301 for inserting the first sleeve 1. In this way, when the accommodating cavity 102 in the first sleeve 1 contains grease, the worker can hold the second sleeve 3 to prevent the grease from directly contacting the worker's hands, thereby reducing the possibility of grease contamination. Moreover, when using grease that is slightly corrosive to the skin, the risk of corrosion of the worker's hands can also be prevented, thereby improving the safety of the lubricating tool during operation.

[0033] In some embodiments, reference Figures 1 to 5 As shown, the lubrication tool also includes a locking mechanism 4 connected to the first sleeve 1 and the second sleeve 3. The locking mechanism 4 includes a locked state and an unlocked state. In the locked state, the first sleeve 1 is inserted into the second sleeve 3 and locked relative to the second sleeve 3. In the unlocked state, the first sleeve 1 can rotate and translate relative to the second sleeve 3. In this way, the first sleeve 1 and the second sleeve 3 are unlockably connected, so that the first sleeve 1 can be disassembled and replaced, that is, the first sleeve 1 of appropriate size can be selected according to the length or diameter of the screw. It can be understood that when the first sleeve 1 is replaced, the locking mechanism 4 connected to the first sleeve 1 and the second sleeve 3 can be switched to an unlocked state. After the first sleeve 1 is translated and removed from the inside of the second sleeve 3, the new first sleeve 1 can be inserted into the second sleeve 3 again, and the locking mechanism 4 can be switched from the unlocked state to the locked state, so that the first sleeve 1 and the second sleeve 3 can be relatively fixed, that is, when the lubrication tool is in use, the first sleeve 1 can be driven to rotate by holding the second sleeve 3, and then the first sleeve 1 can be driven to rotate relative to the screw to lubricate the outer surface of the screw.

[0034] It should be noted that the locking mechanism 4 mentioned in the above embodiment can be constructed as any suitable mechanism that can lock and unlock the first sleeve 1 and the second sleeve 3. For example, the locking mechanism 4 can be a snap hook connected to the first sleeve 1 and the second sleeve 3, or it can be a magnetic part with magnetism, etc. The present disclosure will elaborate on the specific structure of the locking mechanism 4 in detail below, so no further details will be given here.

[0035] In some embodiments, reference Figures 1 to 5 As shown, the locking mechanism 4 includes a locking member 410 and a matching member 420, wherein the locking member 410 includes a locking portion 411 connected to the outer wall of the first sleeve 1, and a first locking groove 412 formed in the locking portion 411 and the outer wall of the first sleeve 1; the matching member includes a matching portion 421 connected to the inner wall of the second sleeve 3, and a second locking groove 422 formed in the matching portion 421 and the inner wall of the second sleeve 3; in the locked state, the locking portion 411 is inserted into the second locking groove 422, and the matching portion 421 is inserted into the first locking groove 412. In this way, when the locking mechanism 4 is in the locked state, it can be referred to Figure 4 and Figure 5 As shown, in the locked state, the locking portion 411 will be inserted into the second locking groove 422, and the matching portion will be inserted into the first locking groove 412. At this time, the locking member 410 and the matching member 420 are locked to each other, so that the first sleeve 1 and the second sleeve 3 can be locked and tightly matched without relative movement. When the first sleeve 1 needs to be taken out of the second sleeve 3 and replaced, the locking mechanism 4 needs to be switched from the locked state to the unlocked state. During the switching process, the locking mechanism 4 can be switched along the Figure 4 and Figure 5 When the locking portion 411 is completely disengaged from the second locking groove 422 and the matching portion 421 is completely disengaged from the first locking groove 412, the locking mechanism 4 is in the unlocked state. At this time, the first sleeve 1 can be rotated relative to the second sleeve 3, that is, when the locking member 410 and the matching member 420 are in the staggered positions, the first sleeve 1 can be pulled out along the length direction of the second sleeve 3 for replacement. Similarly, the replaced new first sleeve 1 is inserted into the first sleeve 1 along the length direction of the second sleeve 3, and the locking member 410 and the matching member 420 are kept in the staggered positions for insertion. Figure 4 and Figure 5 As shown, when the locking member 410 is inserted into the mating member 420, Figure 4 or Figure 5When the first sleeve 1 is turned to the left in the middle direction of the drawing, the first sleeve 1 can be rotated so that when the locking member 410 and the matching member 420 are on the same reference line in the length direction of the first sleeve 1 or the second sleeve 3, the first sleeve 1 can be pulled back, and the locking portion 411 can be inserted into the second locking groove 422, and the matching portion 421 can also be inserted into the first locking groove 412 to complete the matching locking of the first sleeve 1 and the second sleeve 3, that is, the final Figure 3 The status shown.

[0036] In some embodiments, reference Figures 1 to 5 As shown, the lubricating tool further comprises an elastic member 5 connected to the first sleeve 1 and the second sleeve 3, and the elastic member 5 can push the first sleeve 1 in the locked state so as to lock the first sleeve 1 to the second sleeve 3 along the length direction of the second sleeve 3. In this way, you can refer to Figure 4 As shown, when the locking mechanism 4 is in the locked state, the locking portion 411 is inserted into the second locking groove 422, and the matching portion 421 is inserted into the first locking groove 412. At this time, in order to prevent the first sleeve 1 from sliding along the locking groove 422, the locking portion 411 is inserted into the second locking groove 422. Figure 4 The situation that the second sleeve 3 moves to the left in the drawing direction and is separated from the second sleeve 3 occurs, and the first sleeve 1 and the second sleeve 3 can be connected to each other through the elastic member 5, that is, Figure 4 In the embodiment, the elastic member 5 is connected to the outer bottom wall of the first sleeve 1 and to the inner bottom wall of the second sleeve 3. In this way, when in the locked state, the elastic member 5 can provide the first sleeve 1 with a rightward elastic force so that the locking portion 411 can always be inserted into the second locking groove 422, thereby allowing the first sleeve 1 and the second sleeve 3 to be stably locked, and the elastic member 5 can also be compressed when the first sleeve 1 moves to the left relative to the second sleeve 3, so as to leave sufficient movement margin for the first sleeve 1.

[0037] It should be noted that the elastic member 5 mentioned in the above embodiment can be any suitable member. For example, the elastic member 5 can be a spring, a rubber pad or a shock absorber connected to the first sleeve 1 and the second sleeve 3. Figure 4 and Figure 5 In the illustrated embodiment, the elastic member 5 may be a spring.

[0038] In some embodiments, reference Figures 1 to 5 As shown, there are multiple locking mechanisms 4, which are arranged at intervals along the inner side wall of the second sleeve 3 and / or the outer side wall of the first sleeve 1. In this way, when the first sleeve 1 and the second sleeve 3 are locked, the multiple locking mechanisms 4 can be locked together to achieve stable locking, that is, Figures 3 to 5As shown, the present disclosure exemplarily shows a connection diagram of two locking mechanisms 4 locked together. By locking together the two locking mechanisms 4, that is, by inserting multiple locking parts 411 into multiple second locking grooves 422 one by one, and by inserting multiple matching parts 421 into multiple first locking grooves 412 one by one, the stability of the locking mechanism 4 when in a locked state can be improved, and the first sleeve 1 and the second sleeve 3 are less likely to move relative to each other when locked.

[0039] It should be noted that the number of two locking mechanisms 4 mentioned in the above embodiment is for illustration only. In embodiments not shown in the figures, the number of locking mechanisms 4 may be three, four, five or more, and multiple locking mechanisms 4 may be arranged at intervals around the first sleeve 1 and / or the second sleeve 3. The present disclosure does not specifically limit the number of locking mechanisms 4.

[0040] In some embodiments, reference Figures 1 to 5 As shown, the lubricating tool further includes an operating handle 6 connected to the second sleeve 3. In this way, the operating handle 6 can facilitate the operator to hold the lubricating tool. That is, it can be understood that when using the tool, one hand can hold the operating handle 6, and the other hand can hold the screw and insert the screw into the accommodating cavity 102 in the first sleeve 1 for lubrication. When pulling out the lubricated screw, one hand can also hold the operating handle 6 and the other hand can hold the screw and pull them in opposite directions to pull out the lubricated screw. The operation is relatively simple and quick.

[0041] In some embodiments, reference Figures 1 to 5 As shown, the cross-section of the operating handle 6 along its length is hexagonal. In this way, the hexagonal operating handle 6 is convenient for workers to hold. At the same time, the operating handle 6 can also be fixed to other rotating tools, such as a pistol drill, to mechanically drive the rotation, thereby conveniently driving the second sleeve 3 and the first sleeve 1 to rotate to lubricate the screw.

[0042] It should be noted that the cross section of the operating handle 6 along its length may also be any suitable shape according to actual conditions. For example, the cross section of the operating handle 6 may also be a quadrilateral, a pentagon, or other shapes.

[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0045] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
