DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The following combination Figures 1-4A further detailed description is given of the specific embodiments of the present utility model.

[0022] The present utility model includes a sleeve 1 and a sliding rod 2 that can slide up and down inside the sleeve 1. In order to achieve the purpose of cleaning the sliding rod 2, a fixed block 3 is fixedly connected to the upper part of the sleeve 1. A sliding sleeve 4 is threadedly connected to the upper side of the fixed block 3. A cleaning frame 5 that can move up and down relative to the sliding sleeve 4 is provided on the upper side of the sliding sleeve 4. A cleaning brush 6 is fixedly connected to the inner side of the cleaning frame 5. A plurality of cleaning tubes 7 are evenly distributed on the outer side of the cleaning frame 5. The cleaning tubes 7 and the cleaning brush 6 cooperate with each other to form a structure for cleaning the sliding rod 2. The sleeve 1 and the sliding rod 2 are the sleeve and the sliding rod of a shock absorber. A shock-absorbing structure is provided inside the sleeve. For example, a shock absorber with a publication number of CN107237852A achieves a shock-absorbing effect through structures such as an oil inlet chamber, an oil outlet chamber, and a damping channel;

[0023] During use, the sleeve 1 and the sliding rod 2 will slide relative to each other. At this time, the outer side of the sliding rod 2 can be cleaned by the cleaning brush 6. Since the cleaning brush 6 moves up and down with the sliding rod 2 during the relative movement between the cleaning brush 6 and the sliding rod 2, the cleaning brush 6 will move up and down relative to the sliding sleeve 4 at this time, and the cleaning liquid will flow out of the cleaning tube 7 to assist the cleaning brush 6 in cleaning the sliding rod 2.

[0024] Furthermore, in order to facilitate the storage of the cleaning liquid, a liquid storage chamber 8 is fixedly connected to the outer side of the sliding sleeve 4. A communication port 9 is provided at the rear side of the liquid storage chamber 8. The communication port 9 and the liquid storage chamber 8 cooperate with each other to form a structure for storing the cleaning liquid.

[0025] Furthermore, in order to be able to automatically spray the cleaning liquid, a plurality of air pressure chambers 10 are communicated with the upper side of the liquid storage chamber 8. A pneumatic rod 11 is slidably connected to the upper side of each air pressure chamber 10. The upper side of each pneumatic rod 11 is fixedly connected to the cleaning frame 5. A one-way air valve 12 is communicated with the lower part of each air pressure chamber 10;

[0026] During use, when the pneumatic rod 11 moves up and down with the sliding sleeve 4, the lower side of the pneumatic rod 11 moves up and down inside the air pressure chamber 10. When each pneumatic rod 11 moves upward, gas can flow into the air pressure chamber 10 through the one-way air valve 12. When each pneumatic rod 11 moves downward, under the action of the one-way air valve 12, no gas will flow out through the one-way air valve 12, thereby increasing the internal pressure of the liquid storage chamber 8.

[0027] Further, for the convenience of the staff's operation, a plurality of sliding blocks 13 are fixedly connected inside the sliding sleeve 4, and a sliding groove 14 is provided at the position corresponding to each sliding block 13 on the outer side of the cleaning frame 5. The sliding block 13 and the sliding groove 14 cooperate with each other to form a structure in which the cleaning frame 5 moves up and down relative to the sliding sleeve 4;

[0028] During use, through the sliding block 13 and the sliding groove 14, the cleaning frame 5 and the sliding sleeve 4 can move up and down relative to each other.

[0029] Further, in order to make the cleaning more thorough, a hydraulic sleeve 15 is fixedly connected inside the liquid storage cavity 8 at the position corresponding to each cleaning tube 7, and a plurality of communication holes 16 are provided on the lower side of each hydraulic sleeve 15;

[0030] During use, when the internal pressure of the liquid storage cavity 8 increases, the cleaning liquid filled therein will enter the hydraulic sleeve 15 through the communication holes 16 and then flow out through the cleaning tube 7.

[0031] When the present utility model is in use, the sleeve 1 and the sliding rod 2 will slide relative to each other during use. At this time, the cleaning brush 6 can be used to clean a partial area on the outer side of the sliding rod 2. Since the cleaning brush 6 moves up and down along with the sliding rod 2 during the relative movement between the cleaning brush 6 and the sliding rod 2, at this time, the cleaning brush 6 moves up and down relative to the sliding sleeve 4. The cleaning brush 6 is made of rubber material, which can ensure the friction between the cleaning brush 6 and the sliding rod 2 while reducing the damage to the outside of the sliding rod 2. Further, the cleaning brush 6 can also be replaced with a rubber sleeve, which can further increase the cleaning effect on the sliding rod 2. When the pneumatic rod 11 moves up and down along with the sliding sleeve 4, the lower side of the pneumatic rod 11 moves up and down inside the pneumatic cavity 10. When each pneumatic rod 11 moves upward, gas can flow into the pneumatic cavity 10 through the one-way air valve 12. When each pneumatic rod 11 moves downward, under the action of the one-way air valve 12, no gas will flow out through the one-way air valve 12, thereby increasing the internal pressure of the liquid storage cavity 8. When the internal pressure of the liquid storage cavity 8 increases, the cleaning liquid filled therein will enter the hydraulic sleeve 15 through the communication holes 16 and then flow out through the cleaning tube 7 to assist the cleaning brush 6 in cleaning the sliding rod 2. When it is not necessary to use the cleaning brush 6 to clean the sliding rod 2, the sliding sleeve 4 can be rotated. At this time, under the action of the sliding block 13 and the sliding groove 14, the cleaning frame 5 will be driven to move downward relative to the fixed block 3. At this time, the cleaning brush 6 will no longer contact the sliding rod 2. When it is necessary to clean the entire outer surface of the sliding rod 2, the sliding sleeve 4 can be rotated to release the cooperation between the sliding sleeve 4 and the fixed block 3. At this time, the sliding sleeve 4 and the cleaning frame 5 can be held by hand to clean the outer surface of the sliding rod 2.

[0032] The structure of the utility model is novel, the concept is ingenious, and the operation is simple and convenient. Through this design, the purpose of being able to clean the slide rod 2 is effectively realized, which facilitates the storage of the cleaning liquid, can automatically spray the cleaning liquid, facilitates the operation of the staff, and makes the cleaning more thorough.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
