Description

Technical Field

[0001] This utility model relates to the field of mobile shelving technology, specifically a mobile shelving buffer device. Background Technology

[0002] Mobile shelving offers large storage capacity, ease of use, space saving, and convenient management, making it the best choice for government departments and large enterprises to store data. It is a type of furniture and equipment used to preserve various archives and documents, and is widely used in enterprises, institutions, and banks. The emergence of mobile shelving has alleviated the long-standing problem of warehouse shortages and improved the conditions for storing archives.

[0003] To prevent collision damage, some existing mobile shelving units use simple rubber strips or blocks attached to the side panels for cushioning. However, this method has a short cushioning stroke, limited energy absorption, and cannot effectively cope with collisions under large inertia; moreover, the rubber is prone to aging and failure. Other cushioning devices use a single spring structure, which can absorb some impact force, but its linear compression characteristics make it difficult to completely dissipate the impact energy. Furthermore, the energy stored after the collision is released in the form of a rebound, causing the mobile shelving unit to shift unexpectedly and affecting its precise positioning. In addition, these cushioning devices cannot guarantee a tight fit between adjacent units in non-collision states, potentially creating gaps that affect the overall aesthetics and storage space utilization. To address these issues, we propose a mobile shelving unit cushioning device. Utility Model Content

[0004] The purpose of this invention is to provide a mobile shelving buffer device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile shelving buffer device, comprising a fixed frame, wherein the fixed frame includes a frame body and a turntable, and the turntable is installed on the outer side of the frame body;

[0006] A buffer structure is provided, comprising a groove, a buffer plate, and a protective pad. The right wall of the frame has a groove, the inner side of which is fitted with a buffer plate. A protective pad is installed on the outer wall of the buffer plate. Multiple connecting posts are installed on the left wall of the buffer plate. These connecting posts pass through a fixing groove and connect to a sliding plate. The sliding plate is located inside a storage compartment, which is located inside the frame. The fixing groove is located inside the frame. Both sides of the sliding plate are located inside a sliding groove, which is located inside the frame. A first buffer spring is provided on the outer wall of each connecting post, located on the right side inside the storage compartment. A fixing post is installed on the left side of the sliding plate, and a press-type buckle is installed on the left side of each fixing post. The press-type buckle is installed inside a press-type buckle slot, which is located inside the frame. A second buffer spring is provided on the outer wall of each fixing post.

[0007] Preferably, the groove and the buffer plate are correspondingly arranged, and the buffer plate is a rectangular frame.

[0008] Preferably, the buffer plate and the protective pad are tightly fitted together, and the protective pad is made of rubber.

[0009] Preferably, the buffer plate and the connecting column are arranged perpendicularly to each other, and the connecting column and the sliding plate are fixedly connected.

[0010] Preferably, the slide plate and the slide groove are slidably connected, and the slide groove and the frame are integrally formed.

[0011] Preferably, the fixing posts are fixedly connected to the left wall of the slide plate and the press-type buckle, and the press-type buckle and the press-type slot are engaged.

[0012] Preferably, the second buffer spring is sleeved on the outer wall of the fixed column, and the left side of the second buffer spring is fixedly connected to the left wall of the storage tank.

[0013] Preferably, the first buffer spring is sleeved on the outer wall of the connecting column, and both sides of the first buffer spring are fixedly connected to the inner side of the right wall of the slide plate and the right wall of the storage tank.

[0014] Preferably, the push-button buckle, fixing post, sliding plate, and connecting post are on the same horizontal line.

[0015] Preferably, the right wall of the protective pad is on the same horizontal line as the right wall of the frame.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting grooves, buffer plates and protective pads, when the frame moves by the turntable and collides with adjacent frames or obstacles, the rubber protective pad on the outside of the buffer plate contacts the obstacle first. The elastic deformation of the protective pad absorbs the initial impact force, avoiding direct collision with hard metal, preventing the frame from being scratched or deformed, and also preventing sharp impact noise from interfering with the office and reading environment.

[0018] After the protective pad is subjected to force, it drives the buffer plate to move into the groove inside the frame. The connecting column on the left wall of the buffer plate passes through the fixing groove and pushes the slide plate along the sliding groove into the storage groove to ensure that the buffering direction is consistent with the collision direction and there is no deviation. When the slide plate slides, the first buffer spring on the outer wall of the connecting column is compressed to absorb the main impact force. At the same time, the second buffer spring on the outer wall of the fixing column on the left side of the slide plate is also compressed to further absorb the remaining impact force and prevent the spring from rebounding, thus avoiding the frame from shifting after buffering.

[0019] After the impact force disappears, the first and second buffer springs rebound and push the buffer structure to reset. At this time, the push-type buckle on the left side of the fixed column is inserted into the push-type slot inside the frame, fixing the buffer plate in the initial position, making the protective pad flush with the right wall of the frame, ensuring that the two frames fit tightly together and maintaining the original storage capacity.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution for a mobile shelving buffer device: a mobile shelving buffer device, including a fixed frame 1, the fixed frame 1 including a frame body 101 and a turntable 102, the turntable 102 being installed on the outer side of the frame body 101;

[0031] The buffer structure 3 includes a groove 301, a buffer plate 302, and a protective pad 303. The right wall of the frame 101 has a groove 301, the inner side of which is fitted with a buffer plate 302. The outer wall of the buffer plate 302 is fitted with a protective pad 303. The left wall of the buffer plate 302 has multiple connecting posts 304. The connecting posts 304 pass through a fixing groove 305 and connect to a sliding plate 306. The sliding plate 306 is located inside a storage slot 313, which is located inside the frame 101. The fixing groove 305 is located inside the frame 101. The two sides of the slide plate 306 are located inside the slide groove 307, which is located inside the frame 101. The outer wall of the connecting column 304 is provided with a first buffer spring 308, which is located inside the storage groove 313 on the right side. A fixing column 309 is installed on the left side of the slide plate 306, and a press-type buckle 310 is installed on the left side of the fixing column 309. The press-type buckle 310 is installed inside the press-type slot 311, which is located inside the frame 101. The outer wall of the fixing column 309 is provided with a second buffer spring 312.

[0032] The groove 301 and the buffer plate 302 are correspondingly set, and the buffer plate 302 is set as a rectangular frame.

[0033] The buffer plate 302 and the protective pad 303 are tightly fitted together. The protective pad 303 is made of rubber to reduce impact.

[0034] The buffer plate 302 and the connecting post 304 are set perpendicular to each other, and the connecting post 304 and the sliding plate 306 are fixedly connected.

[0035] The slide plate 306 and the slide groove 307 are slidably connected, and the slide groove 307 and the frame 101 are integrated.

[0036] The fixed posts 309 are fixedly connected to the left wall of the slide plate 306 and the push-button buckle 310. The push-button buckle 310 and the push-button slot 311 are engaged to ensure the stability of the structure after buffering.

[0037] The second buffer spring 312 is sleeved on the outer wall of the fixed column 309. The left side of the second buffer spring 312 is fixedly connected to the left wall of the storage tank 313 to absorb the impact force.

[0038] The first buffer spring 308 is sleeved on the outer wall of the connecting post 304, and both sides of the first buffer spring 308 are fixedly connected to the right wall of the slide plate 306 and the inner side of the right wall of the storage tank 313.

[0039] The push-button buckle 310, the fixing post 309, the sliding plate 306, and the connecting post 304 are on the same horizontal line.

[0040] The right wall of the protective pad 303 is on the same horizontal line as the right wall of the frame 101.

[0041] Working principle:

[0042] First, when the frame 101 moves and collides with an adjacent frame 101 or an obstacle via the turntable 102, the rubber protective pad 303 on the outside of the buffer plate 302 contacts the obstacle first. The elastic deformation of the protective pad 303 absorbs the initial impact force, avoiding direct collision with hard metal, preventing the frame 101 from being scratched or deformed, and also preventing sharp impact noise from interfering with the office and reading environment.

[0043] After the protective pad 303 is subjected to force, it drives the buffer plate 302 to move into the groove 301 inside the frame 101. The connecting post 304 on the left wall of the buffer plate 302 passes through the fixing groove 305 and pushes the slide plate 306 to slide along the sliding groove 307 into the storage groove 313, ensuring that the buffering direction is consistent with the collision direction and there is no deviation. When the slide plate 306 slides, the first buffer spring 308 on the outer wall of the connecting post 304 is compressed to absorb the main impact force. At the same time, the second buffer spring 312 on the outer wall of the fixing post 309 on the left side of the slide plate 306 is also compressed to further absorb the remaining impact force and prevent the spring from rebounding, thus avoiding the frame 101 from shifting after buffering.

[0044] After the impact force disappears, the first buffer spring 308 and the second buffer spring 312 rebound and push the buffer structure 3 to reset. At this time, the push-type buckle 310 on the left side of the fixed column 309 is inserted into the push-type slot 311 inside the frame 101, fixing the buffer plate 302 in the initial position, making the protective pad 303 flush with the right wall of the frame 101, ensuring that the two frames 101 fit tightly together and maintain the original storage capacity.

[0045] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
