DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] As shown in the drawings, Figures 1 to 4 The embodiments of the present application provide a screw cleaner, which comprises a fixed assembly 1 and a cleaning assembly 2. The screw to be cleaned is detachably mounted on the fixed assembly 1. The cleaning assembly 2 comprises a driving assembly, an adjusting block and a first cleaning brush 207 provided on the adjusting block. The adjusting block is movable along the axial direction of the screw to be cleaned mounted on the fixed assembly 1. The adjusting block has a first through hole for passing through the screw to be cleaned. The first cleaning brush 207 is at least partially located in the first through hole and in contact with the outer periphery of the screw to be cleaned passing through the first through hole. The driving assembly is drivingly connected with the first cleaning brush 207 to drive the first cleaning brush 207 to rotate around the axis of the screw to be cleaned.

[0025] In the present embodiment, the installation of the screw to be cleaned is realized by the fixed assembly 1, avoiding the screw to be cleaned from moving and affecting the cleaning when the screw to be cleaned is cleaned. Further, in combination with the movement of the fixed block and the rotational driving of the first cleaning brush 207 by the driving assembly, the first cleaning brush 207 can realize all-around cleaning of the outer periphery of the screw to be cleaned, ensuring the reliability of cleaning the outer periphery of the screw to be cleaned and the thread of the screw to be cleaned, and being conducive to improving the applicability of the screw cleaner. Compared with the manual cleaning of the screw to be cleaned in the prior art, the screw cleaner provided by the present solution realizes semi-automatic cleaning of the screw to be cleaned, which is conducive to improving the cleaning effect and the cleaning efficiency of the screw to be cleaned.

[0026] AsFigures 1 to 3 As shown, the adjustment block includes an annular mounting shell 201 and an annular rotating block 202 rotatably mounted in the annular mounting shell 201 through a ball 203. A first through-hole is formed around the inner side of the annular mounting shell 201 and / or the annular rotating block 202. A first cleaning bristle 207 is fixedly arranged on the inner side of the annular rotating block 202 and at least partially extends into the first through-hole. The driving assembly is driven and connected to the annular rotating block 202.

[0027] In this embodiment, the outer periphery of the annular rotating block 202 is positioned relative to the inner wall of the cavity of the annular mounting shell 201. The annular rotating block 202 is rotatably mounted within the annular mounting shell 201 via a plurality of ball bearings 203. The inner side of the annular mounting shell 201 and / or the annular rotating block 202 has an opening for receiving a first cleaning bristle 207. One end of the first cleaning bristle 207 is connected to the inner wall of the annular rotating block 202, and the other end extends into the first through-hole to clean the outer periphery of the screw to be cleaned. This arrangement allows the annular mounting shell 201 to realize the rotational mounting and restriction of the annular rotating block 202 and the first cleaning bristle 207. It also provides a certain degree of protection for the ball bearings 203 between the annular rotating block 202 and the annular mounting shell 201, preventing the relative rotation between the annular rotating block 202 and the annular mounting shell 201 from being affected. The ball bearings 203 reduce frictional resistance during the cleaning process, allowing the annular rotating block 202 to rotate more smoothly and efficiently, reducing heat generated by friction and preventing wear. Furthermore, this smooth rotation method helps reduce noise generated during the cleaning process.

[0028] like Figures 1 to 3 As shown, the drive assembly is fixedly arranged on one side of the annular mounting shell 201, and the drive assembly includes a drive motor 206 and a drive gear 205. The outer periphery of the annular rotating block 202 has a plurality of tooth blocks 204, and the plurality of tooth blocks 204 form annular teeth that mesh with the drive gear 205. The outer periphery of the annular mounting shell 201 has an avoidance opening, and at least part of the drive gear 205 extends into the avoidance opening and meshes with the annular teeth. The drive motor 206 and the drive gear 205 are driven and connected.

[0029] This embodiment uses a gear meshing method to drive the annular rotating block 202 to rotate, which is conducive to improving the accuracy of the rotation control of the annular rotating block 202 and facilitating adaptive adjustment of the rotation speed and torque of the first cleaning bristles 207. For example, when the residue on the surface of the screw to be cleaned is relatively stubborn, the rotation speed and torque can be appropriately increased to achieve a more thorough cleaning, which is conducive to ensuring both cleaning effect and cleaning efficiency. At the same time, it can also avoid the situation where the cleaning effect is poor due to too low a rotation speed or the first cleaning bristles 207 are easily damaged by too high a rotation speed on the outer peripheral surface of the screw to be cleaned.

[0030] Specifically, the first cleaning bristles 207 are annular bristles, and the openings of the first through holes at both ends in the axial direction are flared. In this way, the coverage and cleaning effect of the first cleaning bristles 207 on the outer periphery of the screw to be cleaned are further improved, and the flared openings of the first through holes allow the cleaned dirt to fall from the first through holes along the flared openings, avoiding the situation that the cleaned dirt remains in the first through holes and affects the cleaning effect of the first cleaning bristles 207 on the screw to be cleaned.

[0031] As shown in Figure 1 and Figure 2 , the cleaning assembly 2 further comprises a cleaning block 209 and second cleaning bristles 212. The cleaning block 209 is spaced apart from the adjusting block in the moving direction of the adjusting block and has a second through hole coaxial with the first through hole. The second cleaning bristles 212 are at least partially located in the second through hole and in contact with the outer periphery of the screw to be cleaned passing through the second through hole. The cleaning block 209 is connected with the annular mounting shell 201 or the annular rotating block 202. In this way, the cleaning effect on the outer periphery of the screw to be cleaned is further improved by the second cleaning bristles 212.

[0032] Specifically, as shown in Figure 2 and Figure 4 , the cleaning block 209 comprises a connecting rod 208 and a plurality of sub-blocks distributed circumferentially around the screw to be cleaned. The area surrounded by the plurality of sub-blocks forms the second through hole. Any one of the sub-blocks is connected with the annular rotating block 202 through the connecting rod 208. The cleaning assembly 2 further comprises a cleaning block 210, a first elastic member 213 and a mounting block 211. In the circumferential direction of the second through hole, one cleaning block 210 is arranged between any two adjacent sub-blocks. The second cleaning bristles 212 are arranged on the side of the cleaning block 210 facing the second through hole, and the positions of the second cleaning bristles 212 along the radial direction of the second through hole are adjustable.

[0033] In this embodiment, when the driving assembly drives the annular rotating block 202 to rotate, the annular rotating block 202 also drives the plurality of sub-blocks and the plurality of cleaning blocks 210 to rotate through the plurality of connecting rods 208, thereby realizing synchronous rotation driving of the first cleaning bristles 207 and the second cleaning bristles 212 and improving the cleaning effect on the outer periphery of the screw to be cleaned. On the other hand, by adjusting the position of the second cleaning bristles 212, it can adapt to screws of different diameters and ensure the reliability of the contact between the second cleaning bristles 212 and the outer periphery of the screw to be cleaned. In this embodiment, the number of sub-blocks is 3, the number of cleaning blocks 210 is 3, and the number of second cleaning bristles 212 is 3.

[0034] It should be noted that the first through hole is formed according to actual conditions, for example, one side (the side facing the push plate 215) of the annular mounting shell 201 is sealed, the other side (the side facing the mounting seat 103) of the annular mounting shell 201 is open, at least part of the plane of the annular rotating block 202 is flush with the side of the annular mounting shell 201, the plurality of connecting rods 208 are fixedly connected with the side of the annular rotating block 202, the outer periphery of the annular mounting shell 201 is arranged around the outer periphery of the annular rotating block 202, and the annular mounting shell 201 has an annular clamping groove inside, and the outer periphery of the annular rotating block 202 has an annular clamping area which is adapted in shape to the annular clamping groove, and the annular clamping area is clamped in the annular clamping groove and the rolling fit of the two is realized through the plurality of balls 203.

[0035] Further, the cleaning assembly 2 further comprises a first elastic member 213 and a mounting block 211, the cleaning block 210 has a limiting cavity, the limiting cavity has a limiting opening on the side facing the second through hole, the mounting block 211 comprises a limiting segment and an adapter segment which are limited in size and limited in cooperation with the inner wall of the limiting cavity and the inner wall of the limiting opening respectively, the limiting segment is arranged in the limiting cavity and cooperates with the side of the limiting cavity having the limiting opening, the adapter segment passes through the limiting opening, the second cleaning bristles 212 are arranged on the side of the adapter segment away from the limiting segment, and the first elastic member 213 is arranged in the limiting cavity, one end of the first elastic member 213 abuts against the side of the limiting cavity away from the second through hole, and the other end of the first elastic member 213 abuts against the limiting segment.

[0036] In this way, the second cleaning bristles 212 can always be tightly attached to the outer periphery of the screw to be cleaned by the first elastic member, so that the second cleaning bristles 212 can automatically adapt to the slight changes of the surface of the screw to be cleaned, thereby improving the adaptability and effect of cleaning, especially when cleaning the outer periphery of the irregular surface of the screw to be cleaned, the cleaning effect of the second cleaning bristles 212 is better than that of the first cleaning bristles 207, thereby ensuring the reliability and stability of the second cleaning bristles 212 in cleaning the outer periphery and the thread of the screw to be cleaned. On the other hand, the elastic design can also reduce the hard contact between the second cleaning bristles 212 and the screw to be cleaned, thereby avoiding further damage to the surface of the screw to be cleaned, thereby prolonging the service life of the screw to be cleaned.

[0037] As Figure 1As shown, the fixing assembly 1 comprises a base 101, a mounting seat 103, a limiting piece 104 and a plurality of guide rods 102, the screw to be cleaned is detachably arranged on the mounting seat 103, the base 101 has a mounting area penetrating in the width direction thereof, the two ends of any one of the guide rods 102 are fixedly connected with the two ends in the length direction of the mounting area respectively, the plurality of guide rods 102 are parallel to each other and penetrate through the mounting seat 103 and the adjusting block, the plurality of guide rods 102 are distributed around the circumference of the mounting seat 103 and the adjusting block, the mounting seat 103 is movably arranged on the guide rods 102 and located at one side of the adjusting block, and one end of the limiting piece 104 is movably arranged in the mounting seat 103 and abuts against the guide rods 102.

[0038] In the embodiment, the mounting seat 103 has lugs on both sides in the radial direction, the annular mounting shell 201 of the adjusting block also has lugs on both sides in the radial direction correspondingly, the guide rods 102 are two and arranged in parallel at the same height, and the two guide rods 102 penetrate through the two lugs on both sides in the radial direction of the mounting seat 103 and the two lugs on both sides in the radial direction of the annular mounting shell 201 respectively. The guide rods 102 realize the support and guidance of the annular mounting shell 201 and the mounting seat 103, ensure the coaxiality of the screw to be cleaned and the adjusting block and the stability and positioning accuracy in the cleaning process, avoid the shaking and damage of the screw to be cleaned in the cleaning process, and further improve the cleaning effect. The limiting piece 104 in the embodiment is a limiting screw with a threaded end, one end of which penetrates into the lug on one side in the radial direction of the mounting seat 103 and is connected with the internal thread of the lug, so that the limiting screw can be screwed in or out according to the actual situation, and the end of the limiting screw abuts against the guide rod 102, which has a friction limiting effect on the movement of the mounting seat 103.

[0039] Specifically, the mounting seat 103 has a third penetrating hole for penetrating the screw to be cleaned, the third penetrating hole is coaxial with the first penetrating hole, and the side of the third penetrating hole away from the cleaning assembly 2 has a clamping groove, the shape of the clamping groove is matched with the shape of the end of the screw to be cleaned. In this way, the screw to be cleaned can be fixed, for example, a hexagonal head screw, the shape of the clamping groove is a hexagonal groove matched with the hexagonal head, one end of the hexagonal head screw penetrates through the third penetrating hole from one side of the clamping groove, and the position of the mounting seat 103 can be adjusted as needed until the hexagonal head is clamped in the hexagonal groove to complete the positioning and installation of the screw to be cleaned.

[0040] As Figure 1As shown, the screw cleaner further comprises a push plate 215 movably arranged on the guide rod 102 and located on the side of the adjusting block away from the mounting seat 103, and a second elastic member 214 sleeved on the guide rod 102 and connected to the push plate 215 and the side of the adjusting block close to each other at both ends. In this way, the relative displacement of the push plate 215 and the adjusting block is buffered by the second elastic member 214, facilitating the movement adjustment of the adjusting block by the operator. Specifically, in the embodiment, the push plate 215 is located on the side of the adjusting block away from the mounting seat 103 and arranged on the two guide rods 102, and one second elastic member 214 is correspondingly sleeved on each guide rod 102.

[0041] Preferably, the driving mode of the adjusting block is not limited to the above embodiment, for example, when the outer thread size of the screw to be cleaned matches the hole diameter of the second through hole, the second through hole can be designed as a threaded hole matching the outer thread of the screw to be cleaned. When the cleaning block 209 rotates, the cleaning assembly 2 as a whole will move along the axial direction of the screw to be cleaned due to the meshing of the second through hole and the outer periphery of the screw to be cleaned, realizing the driving of the first cleaning brush 207 and the second cleaning brush 212 by the driving assembly in rotation and movement.

[0042] In summary, the utility model provides a screw cleaner, when cleaning the screw to be cleaned, first, the screw to be cleaned is inserted from the side of the mounting seat 103 with the clamping groove, and the position of the mounting seat 103 is adjusted adaptively until the screw head of the screw to be cleaned is clamped in the clamping groove, and the limiting member 104 (limiting screw) is screwed in to abut against the guide rod 102, thereby realizing the limitation of the position of the mounting seat 103 on the guide rod 102. The driving motor 206 is started to drive the driving gear 205 to rotate, the driving gear 205 drives the annular rotating block 202 and the cleaning block 209 to rotate, thereby realizing the rotational cleaning of the first cleaning brush 207 and the second cleaning brush 212 on the outer periphery of the screw to be cleaned. Then, the operator pushes and pulls the push plate 215 according to the actual situation, realizes the reciprocating adjustment of the position of the annular mounting shell 201, the driving assembly and the cleaning block 209 and other cleaning assemblies 2 as a whole on the guide rod 102 in the axial direction, and then realizes the comprehensive cleaning of the first cleaning brush 207 and the second cleaning brush 212 on the screw to be cleaned in the axial direction. After cleaning, the operator separates the annular mounting shell 201, the driving assembly and the cleaning block 209 and other cleaning assemblies 2 as a whole from the screw to be cleaned through the mounting seat 103 and the push plate 215, and disassembles the cleaned screw. In this way, the semi-automatic cleaning of the screw to be cleaned is realized, which improves the cleaning effect of the screw to be cleaned and is also conducive to improving the cleaning efficiency of the screw to be cleaned. Through the movement and rotational cleaning of the first cleaning brush 207 and the second cleaning brush 212 on the screw to be cleaned, the comprehensiveness and reliability of the cleaning of the outer periphery of the screw to be cleaned and the thread of the screw to be cleaned are ensured, and the cleaning efficiency and effect are improved.
