Description

Technical Field

[0002] Compact shelving, also known as compact cabinets, is a type of compact filing equipment. It can be defined as follows: a shelf with axle wheels installed on the base of a double-column double-sided fixed frame, which can move in a straight line along a small guide rail laid on the ground. Multiple shelves can be brought together or separated as needed.

[0003] The axles and guide rails of existing common compact shelving systems are made of rigid materials, which primarily ensure the strength of the compact shelving system and the load-bearing capacity of the guide rails. However, the rigid axles and guide rails are prone to generating significant noise when in motion. Furthermore, over extended use, dust and debris inevitably accumulate on the guide rails or axles. Furthermore, due to the rigid contact between the axles and guide rails, dust and debris can interfere with the axles and guide rails when the compact shelving system is in motion, causing the compact shelving system to vibrate and generate significant noise. The present invention provides a solution to these problems. Summary of the Invention

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-3 As shown, a compact shelving with anti-seismic and shock-absorbing functions includes a guide rail 1, a frame body 2, a turntable 3, a base frame 5, a connecting shaft 6 and an axle wheel 7. The guide rail 1 is fixedly installed on the ground by foot bolts, and the frame body 2 is fixedly installed on the base frame 5 by bolts to form the entire frame of the compact shelving. The axle wheel 7 is installed at both ends of the connecting shaft 6, and the two ends of the connecting shaft 6 are installed on the end mounting plates 13 of the base frame 5 through bearings. The middle sections of the two connecting shafts 6 pass through the middle connecting plate 12, and the connecting shafts 6 and the connecting plates 12 are installed by bearings. The number of middle connecting plates 12 can be multiple, which provides support points for the connecting shafts 6 and improves its strength. Two connecting shafts 6 are installed at the bottom of each base frame 5, and the base frame 5 is installed on the guide rail 1 through the axle wheel 7. The turntable 3 is connected to the connecting shaft 6 through a transmission mechanism. Specifically, Figure 2 and Figure 3 As shown, the transmission mechanism includes a transmission shaft 8, a driven pulley 9, a pulley mechanism 1 10, a pulley mechanism 2 11, a driving pulley 14 and a belt 15. The driving pulley 14 is connected to the turntable 3, and the driving pulley 14 is connected to the driven pulley 9 through a belt 15. The driven pulley 9 and the driving pulley of the pulley mechanism 1 10 and the driving pulley of the pulley mechanism 2 11 are all installed on the transmission shaft 8. The transmission ratio of the pulley mechanism 10 and the pulley mechanism 2 11 is the same (to ensure that the two connecting shafts 6 have the same rotation speed). Both are pulley structures. The two ends of the transmission shaft 8 are respectively mounted on the base frame 5 and the end mounting plate 13 through bearings. The driven pulleys of the pulley mechanism 1 10 and the pulley mechanism 2 11 are respectively mounted on the two connecting shafts 6 at the bottom of the base frame 5. By rotating the turntable 3, the two connecting shafts 6 can be driven to rotate through the transmission mechanism, thereby causing the frame 2 to move along the track. Similarly, the pulley structure of the above-mentioned transmission mechanism can be replaced with a sprocket structure or other transmission mechanism, which is not described in detail here.

[0027] For further reference, Figure 4-Figure 8The cross-section of the guide rail 1 is I-shaped, and a flexible pad 24 is fixedly installed on the upper end surface of the guide rail 1. The flexible pad 24 is made of flexible wear-resistant material. Side blocks 16 are provided at both ends of the shaft wheel 7. When the shaft wheel 7 is installed on the guide rail 1, the two side blocks 16 are located on both sides of the guide rail 1. The blocks 16 on both sides can limit the axial movement range of the shaft wheel 7. A shaft limiting block 17 is provided on the outside of the side block, and a mounting ring 19 mounting section (cylindrical) is left between the shaft limiting block 17 and the side block 16. The ring 19 can rotate relative to the shaft wheel 7. Specifically, a bearing can be installed on the inner ring of the ring 19, and the bearing is installed on the mounting ring 19 through the bearing. On the mounting section, the side surface of the collar 19 is fixedly connected to one end of the connecting rod 20, and the other end of the connecting rod 20 is fixedly connected to one end of the brush plate 21. The bottom of the brush plate 21 is equipped with a brush roller 23 that can rotate relative to the brush plate 21. The brush roller 23 is provided with bristles. The two ends of the bottom of the brush plate 21 are provided with a clamping mechanism. The clamping mechanism is clamped on both sides of the guide rail 1 and makes the brush roller 23 fit on the flexible pad 24. When the shaft wheel 7 rotates relative to the guide rail 1, the brush roller 23 will rotate relative to the flexible pad 24 under the action of friction, thereby cleaning the surface of the guide rail 1. The flexible pad 24 can increase the contact area between the shaft wheel 7 and the guide rail 1.

[0028] For further reference, Figure 4 A number of evenly distributed countersunk holes 27 are provided on the outer wall of the shaft wheel 7. The opening position of each countersunk hole 27 is chamfered, and the countersunk holes 27 in two adjacent rows are staggered. The countersunk holes 27 can accommodate local deformation on the flexible pad 24. If there is dust and impurities (especially hard solid particles such as small stones) on the surface of the flexible pad 24 or the surface is uneven, under the extrusion force of the guide rail 1 and the shaft wheel 7, the uneven position will tend to deform toward the position of the countersunk hole 27, so that the contact between the guide rail 1 and the shaft wheel 7 is smoother, thereby making the movement process smoother and reducing noise.

[0029] Furthermore, the side block 16 on one side of the shaft wheel 7 is provided with an outer ring gear 18, and the outer ring gear 18 is engaged with a gear 22 installed on the brush plate 21. The gear 22 is keyed to one end of the brush roller 23. By setting the outer ring gear 18 and the gear 22 structure, according to the transmission ratio, the outer ring gear 18 rotates one circle and the gear 22 rotates multiple circles, driving the brush roller 23 to clean the surface of the guide rail 1 in the moving direction of the frame 2.

[0030] Further, such as Figure 6The bottom of the self-adjusting rod 30 is provided with a limiting cap 32, and the self-adjusting rod 30 part between the limiting cap 32 and the clamping rod 26 is covered with a clamping spring 31 in a compressed state; the clamping block 28 is fixedly provided on the other end of the clamping rod 26, and the roller 29 is installed on the clamping surface of the clamping block 28, and the clamping spring pushes the roller on the clamping block 28 to abut against the bottom of the upper end plate of the I-shaped guide rail 1 and can rotate relative to the clamping block 28, and the rotation direction is the same as the length direction of the guide rail 1. The clamping mechanism can not only make the brush roller 23 fit the guide rail for pneumatic cleaning, but also play the role of preventing the frame 2 from tipping over.

[0031] Further, such as Figure 5 As shown, a plurality of evenly distributed mounting holes 25 are provided in the middle of the I-shaped guide rail 1 and pass through the mounting holes 25 from top to bottom. The bottom size of the mounting holes 25 is larger than the middle size. The upper end opening of the mounting holes 25 is a trumpet-shaped structure. The flexible pad 24 is formed by casting a rubber material. The rubber material at the bottom of the flexible pad 24 solidifies in the mounting hole 25 to form a connecting structure, so that the two form a whole.

[0032] Furthermore, two symmetrically distributed rollers 29 are provided on the clamping block 28, and both ends of the rollers 29 are mounted on the clamping surface of the clamping block 28 through bearings. The setting of the rollers 29 makes the friction between them and the guide rail 1 rolling friction, which can reduce scratches and reduce noise.

[0033] Furthermore, limit blocks 4 are provided at both ends of the guide rail 1 , and the limit blocks 4 come into contact with the compact shelving base frame 5 that moves to the edge position. The limit blocks 4 are raised plate-like structures that mainly limit the frame body 2 and the guide rail 1 from slipping off.

[0034] Furthermore, the self-adjusting rod 30 and the limiting cap 32 are bolt structures, and the upper end of the self-adjusting rod 30 is threadedly connected to the connecting block 34. The bolt structure can adjust the elastic force of the clamping spring 31, that is, adjust the fitting force between the brush roller 23 and the guide rail 1, in order to achieve a better cleaning effect.

[0035] The present invention provides a flexible pad structure on the guide rail and a countersunk structure on the rolling side wall of the shaft wheel, so that the rigid contact between the guide rail and the shaft wheel can be converted into flexible contact, effectively reducing noise and improving the smoothness of the movement process, playing a role in shock absorption and vibration reduction. At the same time, a brush roller and a clamping mechanism are provided, which can pre-clean multiple guide rails during the movement process and prevent the frame from tipping over.

[0036] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
