Description

TECHNICAL FIELD

[0001] The present application relates to the field of wiping devices, in particular to a wiping tool. BACKGROUND

[0002] In the field of space aviation oil, there are usually oil tanks, pipelines and oil recovery cylinders for storing and transporting aviation oil. Further, in order to ensure the quality of the oil, a sampler is also provided to sample and detect the aviation oil in the aviation oil transportation system.

[0003] Generally, whether it is an oil tank, an oil recovery cylinder or a sampler, a cylindrical body is adopted, and the outer side of the cylindrical body is in a curved surface structure. Since the oil such as aviation oil is prone to solidify on the inner side wall of the cylindrical body, over a long period of time, it is easy to cause contaminated oil or increase the difficulty of cleaning. In order to ensure the use performance of the sampler and the oil recovery cylinder, the inner side wall of the cylindrical body needs to be wiped regularly to ensure the cleanliness of the inner side wall of the cylindrical body.

[0004] However, in actual use scenarios, especially the cleaning process of the inner side wall of the cylindrical body of the sampler, it is usually through manual operation of a wiping cloth or a wiping towel to wipe, which not only easily causes the clothes and hands of the wiping personnel to be contaminated by the aviation oil, which is difficult to clean, but also easily increases the risk of the wiping personnel inhaling too much aviation oil vapor due to too close contact. In addition, since the inner wall of the oil cylinder body produces hard oil condensate, it is difficult to remove by simply using a wiping cloth or a wiping towel, and the cleaning effect is poor. SUMMARY

[0005] The present application provides a wiping tool. The wiping tool in the present application is beneficial to realize that the flexible oil absorbing member is driven by the handle to extend into and abut against the inner side wall of the oil cylinder body to complete wiping, without the need for the operator to extend his hand into the inner side wall of the oil cylinder body, thereby reducing the contamination of the clothes and hands of the wiping personnel and avoiding the wiping personnel directly inhaling aviation oil vapor. Further, the design of the carrier ring body allows the existence of a hollow part for the operator to observe the wiping condition and make timely adjustments. In addition, a notch is provided on the carrier ring body, so that the notch end of the carrier ring body can hook out foreign matter, thereby improving the cleaning quality.

DETAILED DESCRIPTION

[0038] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following exemplary embodiments described in the detailed description section are not meant to be an all-inclusive description of all aspects of the application. Rather, they are merely examples that can illustrate some aspects of the application as defined by the appended claims.

[0039] In the field of space aviation oil, it is necessary to periodically sample and inspect the aviation oil in the oil delivery system. The sampled oil is placed in a sampler. With the increase of the use time, the inner side wall of the sampler is inevitably attached with the oil and the solidified matter of the oil, which can easily contaminate the subsequent sampling inspection results. Therefore, in the related art, the operator needs to wipe and clean the inner side wall of the sampler between the sampling inspection of the aviation oil to ensure the accuracy of the detection. Generally, the wiping personnel holds a wiping cloth or a wiping tissue and wipes the inner wall of the sampler. This kind of mode can easily contaminate the hands or clothes of the wiping personnel and can also easily cause the wiping personnel to directly contact the aviation oil vapor, which brings a strong uncomfortable feeling.

[0040] Based on this, the present application provides a wiping tool 10, as shown in Figures 1-2 which is applied to wipe the inner side wall of an oil cylinder body, such as an oil cylinder body, and includes a handle 110, a bearing ring body 120, and a flexible oil absorbing member 130.

[0041] ​The carrying ring body 120 is fixedly arranged at one end of the handle 110. The carrying ring body 120 is provided with a first end 1201 and a second end 1202 arranged at a distance from the first end 1201. The flexible oil absorbing member 130 is fixedly arranged on the carrying ring body 120, so that the carrying ring body 120 abuts against the inner side wall of the oil cylinder body through at least part of the flexible oil absorbing member 130.

[0042] It can be understood that the operator can hold one end of the handle 110, and drive the carrying ring body 120 and the flexible oil absorbing member 130 with the other end of the handle 110 to wipe the inner side wall of the oil cylinder body. Further, the carrying ring body 120 has a hollow part, so that the operator can observe the wiping condition of the flexible oil absorbing member 130 through the hollow part, so as to adjust in time, improve the convenience and quality of cleaning.

[0043] In addition, the flexible oil absorbing member 130 can be laid and fixed on the carrying ring body 120, or wound on the carrying ring body 120, etc. In an implementation scenario, the flexible oil absorbing member 130 is laid and fixed on the carrying ring body 120, at this time, the gap formed between the first end 1201 and the second end 1202 can enable the position where the second end 1202 is located to hook up foreign matters, so that foreign matters in the oil cylinder body such as oil solidification or dropped flexible oil absorbing member 130 can be hooked up in time through the second end 1202, so as to facilitate the adjustment of the wiping process. In another implementation scenario, the flexible oil absorbing member 130 is wound on the carrying body, at this time, the gap formed by the interval arrangement between the first end 1201 and the second end 1202 can be used as an outlet for removing the flexible oil absorbing member 130, only need to extrude and accumulate the flexible oil absorbing member 130 to the gap to push out, so as to realize the moving and splitting, which facilitates the wiping process of the flexible oil absorbing member 130.

[0044] In order to improve the wiping performance of the wiping tool 10, in an embodiment, the carrying ring body 120 includes a fixed arm 121 and a rotating arm 122. One end of the fixed arm 121 is provided with the first end 1201, so that one end of the fixed arm 121 is fixedly connected with one end of the handle 110. The other end of the fixed arm 121 is rotatably connected with one end of the rotating arm 122, and the other end of the rotating arm 122 is provided with the second end 1202. The distance between the first end 1201 and the second end 1202 is adjustable by adjusting the relative angle of the fixed arm 121 and the rotating arm 122. The flexible oil absorbing member 130 is fixedly arranged on at least one of the fixed arm 121 and the rotating arm 122. It can be understood that generally, the oil cylinder body such as a sampler is provided, and the inner side wall is usually curved, which has certain orientation or corner that is difficult to be directly covered and wiped by the carrying body. Through the rotating cooperation of the rotating arm 122 and the fixed arm 121, the wiping range of the flexible oil absorbing member 130 is increased and the wiping angle is enriched by adjusting the size of the rotating arm 122, so that the corner of the oil cylinder body can be better wiped and cleaned, and the cleaning effect is improved.

[0045] It should be noted that the rotatable connection between the rotating arm 122 and the fixed arm 121 can be achieved by a rotating shaft, a connecting rod assembly, etc., which is not limited here.

[0046] In an embodiment, as shown in Figures 3-4 , the carrier ring body 120 further comprises a first rotating shaft 123. The fixed arm 121 is rotatably connected with the rotating arm 122 through the first rotating shaft 123, so as to realize the switching of the rotating arm 122 between the first position (as shown in Figure 3 ) and the second position (as shown in Figure 4 ). In this way, the rotatable connection between the fixed arm 121 and the rotating arm 122 is realized by the rotating shaft, which is simple in structure, convenient to set, and conducive to reducing the setting cost.

[0047] In another embodiment, as shown in Figures 5-6 , the wiping tool 10 further comprises a driving assembly 140. The driving assembly 140 comprises a heating element 141 and a memory metal element 142. The memory metal element 142 is arranged between the fixed arm 121 and the rotating arm 122, so that the fixed arm 121 is rotatably connected with the rotating arm 122 through the memory metal element 142 and has a contracted state and an expanded state. The heating element 141 is used for heating the memory metal element 142. At least part of the flexible oil absorption element 130 is fixedly arranged on the rotating arm 122. The heating element 141 comprises a power feeding state and a power-off state. Among them,

[0048] When the heating element 141 is in the power feeding state, the memory metal element 142 is switched from at least the first temperature to the second temperature, so that the memory metal element 142 is in the expanded state (equivalent to the first stretching length or the first rotation vector), and the relative rotation between the fixed arm 121 and the rotating arm 122 is driven to present the first angle. When the heating element 141 is in the power-off state, the memory metal element 142 is switched from at least the second temperature to the first temperature, so that the memory metal element 142 is in the contracted state (equivalent to the second stretching length or the second rotation vector), and the fixed arm 121 and the rotating arm 122 present the second angle. The first temperature is less than the second temperature. The first angle is greater than the second angle. The first stretching length is greater than the second stretching length, and the first rotation vector is greater than the second rotation vector.

[0049] It can be understood that in some use scenarios without the need for explosion protection, such as for storing non-flammable substances such as water, the electric control driving is achieved through the driving assembly 140, and specifically, the memory metal piece 142 has different elongation or rotation amount in the high-temperature state and the low-temperature state. Specifically, in the high-temperature state, the memory metal piece 142 is in a stretched state, so as to abut against the pushing rotating arm 122 to move in a direction away from the fixed arm 121, so that the rotating arm 122 and the fixed arm 121 are switched from the first angle to the second angle, and the process of rotating swing is equivalent to that of a wiper, which can increase the wiping area of the flexible oil absorbing piece 130, thereby improving the cleaning effect. In addition, the process of rotating swing can make one end of the rotating arm 122 rotate to a corner position, so that the rotating arm 122 drives the flexible oil absorbing piece 130 to wipe the corner position, ensuring that the wiping of the inner wall of the oil cylinder is in place.

[0050] When the heating piece 141 no longer heats the memory metal piece 142, the temperature of the memory metal piece 142 decreases to return to the original shape, so that the memory metal piece 142 pulls the rotating arm 122 to move in a direction close to the fixed arm 121, so that the rotating arm 122 and the fixed arm 121 are switched from the second angle to the first angle, forming secondary scraping.

[0051] Therefore, when it is necessary to adjust the adjustment angle of the rotating arm 122 and the fixed arm 121, the operator does not need to stretch his hand to adjust, but only needs to turn on the heating piece 141 switch to heat the memory metal piece 142, so as to achieve the angle adjustment between the rotating arm 122 and the fixed arm 121, and play a role of hanging brush, thereby improving the installation range of the flexible oil absorbing piece 130, and being conducive to improving the cleaning effect.

[0052] It should be noted that the heating piece 141 can be but is not limited to an infrared heating piece 141, and can also be an electric heating rod or the like. In addition, the rotating cooperation between the fixed arm 121 and the rotating arm 122 can be achieved through a rotating shaft piece, or through a torsional spring or the like, which is not limited here. In addition, the thermal connection between the heating piece 141 and the memory metal piece 142 can be achieved by fixing the heating piece 141 and the memory metal piece 142, and separately arranging a power supply and an electric wire to be electrically connected with the heating piece 141; or by fixing the heating piece 141 to the other end of the handle 110 away from the bearing ring body 120, so that the handle 110 and the bearing ring body 120 act as a medium for heat conduction or electric conduction, so as to transfer heat to the memory metal piece 142.

[0053] In some embodiments, as shown in FIG. 1, the flexible oil absorbing piece 130 is arranged on the rotating arm 122, and the flexible oil absorbing piece 130 is arranged on the rotating arm 122. Figure 5As shown, the memory metal piece 142 comprises a memory metal torsion spring. The fixed arm 121 is rotatably arranged with the memory metal torsion spring and the rotating arm 122, so as to switch the fixed arm 121 and the rotating arm 122 between the first angle and the second angle. In this way, by the arrangement of the memory metal torsion spring, the structure is small, convenient to arrange, and no additional mounting part is needed, saving the machining process and improving the machining efficiency.

[0054] In other embodiments, as shown in FIG. 1C, the bearing ring body 120 further comprises a second rotating shaft piece 124, and the memory metal piece 142 comprises a memory metal spring. The memory metal spring is clamped between the fixed arm 121 and the rotating arm 122. It can be understood that at this time, the fixed arm 121, the rotating arm 122 and the memory metal spring form a triangular structure, and the length of the side of the triangle is adjusted by the expansion and contraction of the memory metal spring, so as to drive the corresponding angle, i.e. the included angle between the fixed arm 121 and the rotating arm 122, to switch between the first angle and the second angle. In this way, the structure is simple, and the triangular structure can improve the supporting strength of the bearing ring body 120, and can also scrape and clean some foreign matters with relatively large hardness. Figure 6 In combination with any of the above embodiments of the bearing ring body 120, the flexible oil absorption piece 130 is detachably connected with the bearing ring body 120. In this way, by the detachable connection between the flexible oil absorption piece 130 and the bearing ring body 120, the flexible oil absorption piece 130 can be replaced, so as to avoid the decrease of the cleaning ability of the flexible oil absorption piece 130 due to too many times of use, and ensure the cleaning ability of the flexible oil absorption piece 130 to the inner side wall of the oil cylinder body.

[0055] It should be noted that the detachable mode between the flexible oil absorption piece 130 and the bearing ring body 120 can be, but is not limited to, clamping, bonding and the like, and can also be friction fit and the like, which is not limited here.

[0056] In a specific embodiment, as shown in FIG. 1D, the bearing ring body 120 is provided with a friction layer 125, and the flexible oil absorption piece 130 is fixed to the driving assembly 140 through the friction layer 125. The friction layer 125 can be a magic tape, an abrasive surface and the like, which is not limited here. It can be understood that by using the design of the friction layer 125, the flexible oil absorption piece 130 is fixed to the bearing ring body 120 by static friction, which is simple in structure and convenient to arrange. Further, unlike the clamping structure and the like, no mounting structure needs to be arranged on the surface of the bearing ring body 120, and the design of the friction layer 125 can make the flexible oil absorption piece 130 remain on the same plane or curved surface, so as to maximize the wiping of the flexible oil absorption piece 130 to the inner side wall of the oil cylinder body.

[0057] Figure 7 It can be understood that by using the design of the friction layer 125, the flexible oil absorption piece 130 is fixed to the bearing ring body 120 by static friction, which is simple in structure and convenient to arrange. Further, unlike the clamping structure and the like, no mounting structure needs to be arranged on the surface of the bearing ring body 120, and the design of the friction layer 125 can make the flexible oil absorption piece 130 remain on the same plane or curved surface, so as to maximize the wiping of the flexible oil absorption piece 130 to the inner side wall of the oil cylinder body.

[0058] ​Specifically, in an example, the friction layer 125 can be a rubber layer. In this way, the fixing effect is guaranteed by the static friction between the rubber layer and the flexible oil absorption piece 130, and the characteristics of the rubber layer and the oil film being mutually insoluble can facilitate the cleaning of the rubber layer.

[0059] In another specific embodiment, the carrier ring body 120 is provided with a clamping portion protruding from the surface of the carrier ring body 120, so that the clamping portion and the surface of the carrier ring body 120 have a clamping gap. The flexible oil absorption piece 130 is clamped in the clamping gap to achieve fixation. In this way, this fixing method has good fixing effect and is not easy to fall off, which can guarantee the wiping performance of the wiping tool 10.

[0060] It should be noted that the flexible oil absorption piece 130 can be oil absorption paper, paper towel, etc., which is not limited here.

[0061] In some embodiments, the flexible oil absorption piece 130 includes at least one of oil absorption paper, paper towel, nylon cloth, and fiber cloth. In this way, the flexible oil absorption piece 130 has lower cost and higher availability, which can reduce the manufacturing cost. Specifically, in another embodiment, the flexible oil absorption piece 130 can include at least two of oil absorption paper, paper towel, nylon cloth, and fiber cloth, which can be switched according to different use scenarios to improve the wiping performance of the wiping tool 10.

[0062] In combination with any of the above embodiments of the handle 110, as shown in Figures 8-9 The handle 110 includes a handle body 111 and a telescopic piece 112. The first end 1201 is fixed to the handle body 111, so that the carrier ring body 120 is fixedly connected to one end of the handle body 111. The telescopic piece 112 is fixedly connected to the other end of the handle body 111. The handle body 111 adjusts the length of the handle body 111 through the telescopic piece 112. It can be understood that the operator holds the telescopic piece 112 away from the end of the handle body 111 to control the depth of the carrier ring body 120. When it is necessary to continue to wipe the inner side wall of the oil cylinder body, the length of the telescopic piece 112 can be adjusted to increase the distance between the operator's hand and the carrier ring body 120, so that the bottom of the oil cylinder body can be wiped, improving the cleaning range.

[0063] It should be noted that the telescopic piece 112 can be a telescopic rod, a folding rod, etc., which is not limited here.

[0064] In some embodiments, the handle body 111 is provided with at least two elastic pins 1111 arranged at intervals along the length of the handle 110. The telescopic member 112 is provided with grooves that are buckled with the elastic pins 1111. The handle body 111 is fixedly connected with the handle body 111, and the telescopic member 112 is sleeved with the handle body 111, so that the telescopic member 112 can be telescopically connected with the handle body 111. When the elastic pins 1111 and the grooves are locked, the handle body 111 and the telescopic member 112 are relatively fixedly arranged; when the elastic pins 1111 and the grooves are arranged at intervals, the handle body 111 can slide relative to the telescopic member 112, so that the telescopic member 112 can slide along the length of the handle 110 to adjust the length of the handle 110.

[0065] In other embodiments, the handle body 111 and the telescopic member 112 are rotatably connected, so that the handle body 111 can be folded relative to the telescopic member 112. In this way, the length adjustment is achieved by folding, and the structure is simple and convenient to set.

[0066] The above description is only the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
