[0033] like Figure 1 A bolt cleaner 1 is shown, comprising a bolt cleaner body 11 of a cylindrical structure, and a protective plate 12 covering the bolt cleaner body 11, the protective plate 12 being provided with a through hole 121 for the bolts to be cleaned to pass through, a bolt cleaning steel brush 16 being installed on the inner wall of the bolt cleaner body 11, and a rotating shaft 14 extending from the bottom of the bolt cleaner body 11, which is driven to rotate by an external driving device.

[0034] The operating steps of using the bolt cleaner 1 of the present application to clean bolts are as follows:

[0035] The first step is to install the bolt to be cleaned on a fixed seat; the second step is to install the bolt cleaner 1 on an electric tool to drive it to rotate, and the electric tool is an electric drill tool; the third step is to wrap the bolt cleaner 1 around the bolt to be cleaned, and then drive the bolt cleaner 1 to rotate to clean the bolt to be cleaned; or the rotating bolt cleaner 1 is brought close to the bolt to be cleaned and completely wrapped to clean it, and the bolt cleaner 1 is withdrawn after the cleaning is completed.

[0036] The bolt cleaner body 11 is a cylindrical structure. Figure 2 As shown in FIG. 1 , the structure facilitates the distribution of multiple sets of bolt cleaning steel brushes 16 around the center of the bolt cleaning device body 11 and installation along the inner wall. The bolt cleaning steel brushes 16 can be composed of a brush holder and a steel wire. The central space formed after the brush holder back of the bolt cleaning steel brush 16 is arranged along the inner wall of the bolt cleaning device body 11 is as shown in FIG. Figure 3 As shown, it can accommodate the bolts to be cleaned.

[0037] The bottom of the bolt cleaner body 11 is fixedly connected with a rotating shaft 14, which can be welded or integrally formed with the bolt cleaner body 11 and the rotating shaft 14. The rotating shaft 14 is preferably arranged at the center of the bottom of the bolt cleaner body 11. After the rotating shaft 14 is connected to the driving device, the rotating shaft 14 can be driven to rotate evenly.

[0038] The protective plate 12 is disposed on the top of the bolt cleaner body 11, and the protective plate 12 is detachably connected to the bolt cleaner body 11. A through hole 121 is provided on the protective plate 12. Figure 1 As shown, the through hole 121 is provided so that the bolt to be cleaned can enter the interior of the bolt cleaner body 11. The protective plate 12 can prevent the splashing of rust spots, debris, etc., which is convenient for the collection of the cleaned debris, and also provides further protection for the fixation of the bolt cleaning steel brush 16. It should be noted that the bolts to be cleaned are different in model, and the sizes of the bolt cleaner body 11, protective plate 12, and bolt cleaning steel brush 16 used in conjunction with the bolt cleaning body 11 need to match the model of the bolt to be cleaned. Therefore, providing multiple models of protective plates 12, multiple models of bolt cleaner bodies 11, and bolt cleaning steel brushes 16 can cope with the cleaning of various bolts.

[0039] Specifically, the rotating shaft 14 is installed on a driving device such as an electric drill tool. When driven by the driving device, the rotating shaft 14 rotates, and the rotating shaft 14 drives the bolt cleaner body 11 to rotate, thereby driving the bolt cleaning steel brush 16 to rotate. The bolt cleaning steel brush 16 cleans the bolts to be cleaned while rotating. After the bolt cleaning is completed, the bolt cleaner 1 is withdrawn.

[0040] The bolt cleaning operation is simple and convenient, which greatly improves the efficiency of bolt cleaning. At the same time, the structure is small and the volume is compact, which is easy to carry, bringing great convenience to operators when cleaning bolts in various places.

[0041] Furthermore, a steel brush fixing groove 13 is extended outwardly from the inner wall of the bolt cleaner body 11 , and a bolt cleaning steel brush 16 is installed in the steel brush fixing groove 13 .

[0042] The steel brush fixing groove 13 is arranged inside the bolt cleaner body 11. Figure 3 As shown. The steel brush fixing groove 13 provides an installation space for the bolt cleaning steel brush 16, and the brush holder of the bolt cleaning steel brush 16 is accommodated in the steel brush fixing groove 13. The length of the steel brush fixing groove 13 can be long or short, and can extend from the top to the bottom of the bolt cleaner body 11, or can be set in the upper area of ​​the bolt cleaner body 11, and the length of the brush holder of the bolt cleaning steel brush 16 matches the length of the steel brush fixing groove 13. The bolt cleaning steel brush 16 can be directly placed in the steel brush fixing groove 13 and pressed at the top by the protective plate 12, or the bolt cleaning steel brush 16 can be detachably connected in the steel brush fixing groove 13, so as to facilitate the replacement of the bolt cleaning steel brush 16.

[0043] A bolt cleaning steel brush 16 can be fixedly connected to the inner wall of the cylindrical bolt cleaner body 11. This design will make the inner diameter of the bolt cleaner body 11 larger, thereby making the volume of the bolt cleaner 1 larger. The inner wall of the bolt cleaner body 11 is designed to have a steel brush fixing groove 13 extending outward, which reduces the volume of the bolt cleaner 1. This setting only requires extending the position area where the brush seat of the bolt cleaning steel brush 16 needs to be installed outward, and other areas do not need to be extended.

[0044] Furthermore, the steel brush fixing groove 13 and the bolt cleaning steel brush 16 are arranged in pairs on the inner wall of the bolt cleaner body 11 and are evenly distributed.

[0045] The steel brush fixing groove 13 and the bolt cleaning steel brush 16 are paired and arranged into a group, and multiple groups can be arranged, and the multiple groups are evenly distributed on the inner wall of the bolt cleaner body 11, such as Figure 3 The embodiment shown is provided with four groups of steel brush fixing grooves 13 and bolt cleaning steel brushes 16 for pairing. The evenly distributed arrangement enables the bolt cleaner 1 to rotate stably when cleaning the bolts under the rotation of the bolt cleaner 1, and the bolt cleaning is also even and thorough at the same time.

[0046] Furthermore, the end of the bolt cleaning steel brush 16 abuts against the bolt to be cleaned, thereby causing the bolt cleaning steel brush 16 to deform.

[0047] In order to further improve the efficiency of bolt cleaning and the convenience of operation, multiple sets of bolt cleaning steel brushes 16 are evenly distributed on the inner wall of the bolt cleaner body 11. When cleaning, the bolts to be cleaned are passed into the bolt cleaner 1. The diameter of the middle space formed after the multiple sets of bolt cleaning steel brushes 16 are installed is slightly smaller than the outer diameter of the bolts to be cleaned, so that the bolts to be cleaned are fully abutted against the tip of the bolt cleaning steel brush 16, so that the bolt cleaning is more thorough. It should be noted that different models of bolts to be cleaned need to match different models of bolt cleaning steel brushes 16 and bolt cleaner bodies 11 to achieve better results.

[0048] Furthermore, the bolt cleaning steel brush 16 is bolted to the steel brush fixing groove 13 .

[0049] In order to improve the connection stability between the bolt cleaning steel brush and the steel brush fixing groove, the bolt cleaning steel brush 16 is bolted to the steel brush fixing groove 13 as a preferred embodiment, specifically, a threaded hole is opened on the steel brush fixing groove 13, and a clamping bolt is used to stably install the bolt cleaning steel brush 16 in the steel brush fixing groove 13. In this embodiment, when the bolt cleaner 1 rotates at a high speed, the protective plate 12 will not be affected by the bolt cleaning steel brush 16, and the impact pressure of the bolt cleaning steel brush 16 on the protective plate 12 is reduced.

[0050] Furthermore, a fastening groove 15 is provided on the outer wall of the bolt cleaner body 11 , and a fastener 122 is provided on the protective plate 12 , and the fastener 122 and the fastening groove 15 are matched and buckled.

[0051] The protective plate 12 is covered on the bolt cleaner body 11 and is detachably connected to the bolt cleaner body 11. The specific detachable method is to set a fastening groove 15 on the top of the outer wall of the bolt cleaner body 11, and set a fastener 122 on the edge of the protective plate 12. The positions of the fastener 122 and the fastening groove 15 correspond to each other, and the structures of the two are matched. Stable installation can be achieved by buckling, and the operation is convenient, which facilitates the disassembly and installation of the protective plate 12.

[0052] like Figure 4 A nut cleaner 2 is shown, comprising a nut cleaner shaft 21 and a nut cleaning steel brush 22, wherein the nut cleaner shaft 21 is fixedly connected to the nut cleaning steel brush 22, and the nut cleaner shaft 21 is connected to a driving device.

[0053] The present application also provides a nut cleaner 2, which has a simple structure and includes a nut cleaner shaft 21 and a nut cleaning steel brush 22. The nut cleaner shaft 21 and the nut cleaning steel brush 22 are fixedly connected, and the fixed connection can be welding, bolting, etc. The nut cleaning steel brush 22 is a steel wire densely distributed axially and evenly on the brush shaft. When cleaning the nut, first fix the nut to be cleaned on a fixed seat, and then install the nut cleaner shaft 21 on an electric tool. The electric tool drives the nut cleaner shaft 21 to rotate, thereby driving the nut cleaning steel brush 22 to rotate, and then the rotating nut cleaning steel brush 22 is extended into the threaded inner hole of the nut to be cleaned, so as to achieve the cleaning of the nut. It should be noted that different types of nuts can choose different types of nut cleaning steel brushes 22 to match them to achieve the best cleaning effect.

[0054] Furthermore, the nut cleaning steel brush 22 abuts against the nut to be cleaned, thereby causing the nut cleaning steel brush 22 to deform.

[0055] In order to further improve the efficiency of nut cleaning, a model is selected in which the outer diameter of the nut cleaning steel brush 22 is slightly larger than the inner diameter of the threaded inner hole to be cleaned, so that when the nut cleaning steel brush 22 is inserted into the threaded inner hole of the nut to be cleaned, the nut cleaning steel brush 22 and the nut to be cleaned are in an interference fit state, and the steel wire fully abuts against the inner wall of the threaded hole, making the nut cleaning more thorough.

[0056] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0057] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
