Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mobile compact shelves, in particular to a compact shelf convenient to move. BACKGROUND

[0002] The compact shelf convenient to move is a shelf system for storing and organizing items, which is characterized by easy movement and rearrangement. It is usually composed of shelves with axles and can be easily moved to different locations when needed. This shelf system is commonly used in warehouses, libraries, archives, and other places where items need to be frequently accessed and managed. The compact shelf convenient to move can save space, improve storage efficiency, and provide convenience for people, enabling users to better organize and manage stored items.

[0003] During the use of existing compact shelves, the smoothness of the compact shelf movement is affected by the accumulation of dust and impurities inside the track. When the compact shelf moves unsmoothly on the track, it may cause the compact shelf to shake during movement. If files or books are placed on unstable shelves, they may fall out of the shelf, causing damage to the files or books. If important files or books are involved, the loss will be difficult to estimate.

[0004] In addition, during the long-term movement of the compact shelf, the internal parts and track of the compact shelf will inevitably cause some wear and tear. If the parts are not lubricated in a timely manner, the maintenance cost of the compact shelf will continue to rise, and the degree of wear and tear of the parts directly affects the service life of the compact shelf. During the use of the compact shelf, the internal precision parts and track of the compact shelf will inevitably be worn to some extent. If we cannot effectively lubricate and maintain these parts in a timely manner, we will have to spend more maintenance costs to ensure the normal use of the compact shelf, and even the service life of the compact shelf may be significantly shortened due to the aggravation of the wear and tear of the parts. This situation will bring negative effects to the daily use of the compact shelf and the operating cost of the compact shelf.

[0005] Therefore, a compact shelf convenient to move is proposed to solve the above problems. SUMMARY

The first cleaning sheet 207, the second cleaning sheet 209 and the sweeping rod 408 are all made of rubber material.

[0048] The working principle and process of all the above embodiments are as follows:

[0049] The working process of the track assembly cleaning component: when the main frame 1 moves, the first roller 201 moves synchronously with the track column 202 due to the existence of the first rotating shaft 203, and the tracking rod 206 is inserted into the track column 202 at the end close to the track column 202, so when the track column 202 rotates, and due to the upper end of the tracking rod 206 being attached to the inner groove on the surface of the track column 202, the tracking rod 206 will reciprocate along the inner groove on the surface of the track column 202, and since the first cleaning sheet 207 is fixedly connected to the end of the tracking rod 206 away from the track column 202, when the tracking rod 206 reciprocates, the first cleaning sheet 207 will reciprocate synchronously with the tracking rod 206, and the first cleaning sheet 207 is attached to the inner wall of the roller track 204, which achieves the purpose of moving the dense frame while cleaning the roller track 204, the middle position of the tracking rod 206 is fixedly connected with the connecting rod 205, and the two sides of the connecting rod 205 are fixedly connected with the fixed rod 208, the middle position of the fixed rod 208 is fixedly connected with the second cleaning sheet 209, so the tracking rod 206 will reciprocate synchronously with the connecting rod 205, the two ends of the connecting rod 205 slide in the limiting groove 210, that is, the connecting rod 205 reciprocates synchronously with the fixed rod 208 and the second cleaning sheet 209, and the second cleaning sheet 209 is located at the position close to the top end of the two ends of the connecting rod 205, so the second cleaning sheet 209 can sweep the dust on the upper side of the middle of the roller track 204 into the track of the roller track 204, and then the first cleaning sheet 207 sweeps it uniformly, four dust inlets 211 and dust collecting grooves 212 are arranged at the bottom of the roller track 204, the first cleaning sheet 207 can sweep the dust into the dust collecting groove 212, at the same time, a pull rod 213 is fixedly connected to one end of the dust collecting groove 212, and the user can take out the dust collecting groove 212 from the dust inlet 211 at any time according to the actual needs, and pour out the dust in it;

[0050] The working process of lubricating the track assembly: the main frame 1 moves, and due to the presence of the second rotating shaft 302, the second roller 301 rotates synchronously with the second rotating shaft 302, and the rotation of the second rotating shaft 302 drives the first transmission belt 303 to rotate, which drives the third rotating shaft 304 to rotate, and the two ends of the third rotating shaft 304 rotate in the rotating shaft groove 305, at this time the third rotating shaft 304 is provided with an oil box 307 between the inner wall of the slot 101 on the upper side and the third rotating shaft 304, when the third rotating shaft 304 rotates, the oil box 307 is driven by the third rotating shaft 304 to rotate, and the rotation of the oil box 307 drives the oil to be more evenly dropped onto the second roller 301, and the spring 311 is fixedly connected between the inner wall of the oil box 307 and the push rod 310, when the track needs to be lubricated, the user can push the rotating rod 312 to drive the push rod 310, that is, to open the rod oil dripping groove 308 and the shaft oil dripping port 309, to lubricate the roller track 204 and the third rotating shaft 304, and the limiting base 313 is provided with two gear positions that can release different amounts of oil, and the user can adjust the amount of oil dripping according to actual needs, and the oil box 307 is provided with an oil inlet 314, and a locking rod 315 is provided correspondingly, and the end of the locking rod 315 close to the oil inlet 314 is provided with a clamping protrusion 316, and the user can rotate the clamping protrusion 316 to make it rotate in the track of the sliding groove 317, so as to lock the locking rod 315, and the user can open or close the oil inlet 314 through the locking rod 315;

[0051] The working process of the top end assembly of the cleaning frame body: the user shakes the rocker 404, and the rocker 404 drives the fourth rotating shaft 402 fixedly connected to the fixed block 403 to rotate synchronously, thereby driving the second transmission belt 401, and the second transmission belt 401 drives the fifth rotating shaft 405, and the rotation of the fifth rotating shaft 405 drives the third transmission belt 406 to move, and the two ends of the sweeping rod 408 are fixedly connected to the third transmission belt 406, so at this time the sweeping rod 408 moves synchronously with the third transmission belt 406, thereby achieving the purpose of cleaning the top end of the frame body, and the baffle 407 can fix the third transmission belt 406, and the top end of the main frame 1 away from the fifth rotating shaft 405 is fixedly connected with a limiting strip 409, and the purpose of setting the limiting strip 409 is to limit the moving distance of the sweeping rod 408, so as to prevent the sweeping rod 408 from falling off the top end of the frame body.
