Description

Technical Field

[0001] This invention relates to the field of mobile shelving assembly technology, and in particular to a tool-free quick-assembly structure for modular mobile shelving with full snap-fit ​​mortise and tenon joints. Background Technology

[0002] Mobile shelving units are storage devices used to store documents, archives, books, and other materials. They are widely used in archives, libraries, and enterprises. Traditional mobile shelving units typically consist of multiple components such as frames, side panels, and base panels. These components are mostly fixed together using screws, welding, or riveting. Installation is usually done with tools, which is cumbersome, labor-intensive, and inefficient. Summary of the Invention

[0003] The purpose of this invention is to provide a tool-free quick-assembly structure for modular mobile shelving units with full snap-fit ​​mortise and tenon joints, which can be quickly assembled without the aid of tools.

[0004] This invention provides a tool-free quick-assembly structure for a modular mobile shelving unit with full snap-fit ​​mortise and tenon joints, including a frame, side panels, and a base plate. The frame is the skeleton component of the mobile shelving unit, divided into front and rear sides. The individual frame members are connected to form the overall frame of the mobile shelving unit. The side panels are the enclosed space of the mobile shelving unit, used to enclose the back and sides of the mobile shelving unit. The base plate is the part of the mobile shelving unit that prevents items from falling off, used to separate the internal space formed by the frame and side panels.

[0005] The connection between the frames is achieved through the engagement of the female and male snap fasteners. The female snap fastener includes a support rod, a base plate, and a locking rod. The support rod is connected to one of the frames to be connected, and the other end of the support rod is fitted with a base plate. Locking rods are installed on both sides of the bottom of the base plate. The female snap fastener includes a bracket, a locking plate, a sliding plate, a slide groove, a compression spring, and a locking slot. There are two brackets, which are mirror-installed inside the other frame to be connected. The bracket has a locking plate inside, which is slidably installed inside the bracket through the sliding plates installed on both sides and the slide groove opened on the bracket. The rear of the locking plate is connected to the bracket through two compression springs, and the front end of the locking plate has a locking slot that engages with the locking rod.

[0006] When the two frames are joined together, the extension rod of the sub-clamp installed on one frame is inserted into the interior of the other frame. The extension rod drives the base plate to pass over the clamping plate. During this period, the compression spring pushes the clamping plate to move. The clamping plate drives the sliding plate to slide inside the slide groove to maintain the stability of the movement. When the clamping plate moves to directly below the clamping rod, the clamping rod is engaged in the interior of the latch. At this time, the sub-clamp and the female clamp are connected, and the two frames are also connected and fixed.

[0007] The enclosure is installed on the frame. The connection between the enclosure and the frame is achieved through a first tenon and a second tenon and a second tenon and a third tenon and a fourth tenon and a fifth tenon and a sixth ...

[0008] When the panel is connected to the frame, the panel drives the snap-fit ​​block in the first tenon assembly to be inserted into the interior of the frame through the second socket. Then, the fixing block in the second tenon assembly is inserted into the interior of the frame through the first socket and is fixed in place by the snap-fit ​​groove. During this process, the limiting protrusion and the limiting groove are inserted. Then, the first limiting plate and the second limiting plate, which are facing opposite directions, press against each other. After the two limiting plates pass each other, they are reset. The two limiting plates are in a state similar to two hooks hooking each other, connecting the first tenon assembly and the second tenon assembly. At this time, the panel and the frame are connected.

[0009] The seat plate is installed on the frame, and a fixing component is installed on the frame to fix the seat plate. The fixing component includes a vertical plate, which is installed on the frame. A sliding opening is opened at the center of the vertical plate, and a sliding frame is slidably installed inside the sliding opening. One end of the support plate is installed on the front of the sliding frame, and a fixing post is installed on the other end of the support plate. When the seat plate is placed on the frame, the fixing post clamps the outer edge of the seat plate for fixation.

[0010] When the seat plate is placed on the frame, push the sliding bracket downwards to slide inside the sliding opening. The sliding bracket drives the extension plate to move, and the extension plate drives the fixed support to clamp the side of the seat plate. The side of the seat plate clamped by the fixed support is flat, with a wide contact area, which can improve the clamping effect. The side of the seat plate is clamped by the protrusion of the fixed support, and the seat plate is installed on the frame.

[0011] The control assembly is used to separate the two plates when the frame is mated so that the extension rod can pass through. The control assembly includes push rods and connecting cylinders. One end of the two push rods is movably connected to the sliding plate through an opening in the sliding plate. The other end of the two push rods is provided with a connecting cylinder and is movably connected to it. When the connecting cylinder is pressed, the connecting cylinder drives the two push rods to move. The push rods push the two plates apart, and at this time the extension rod drives the seat plate to pass through.

[0012] As a further optimization, the female snap fastener includes a support rod that connects to a frame to be connected. A base plate is mounted on the other end of the support rod, and locking rods are mounted on both sides of the bottom of the base plate. This structure simplifies the construction of the female snap fastener, facilitating manufacturing, while the locking mechanism between the locking rods and the snap-fit ​​provides reliable connection strength.

[0013] As a further optimization, the sub-clamp includes a bracket, which has two brackets and is mirror-installed inside the other frame that needs to be connected. The bracket has a locking plate inside, which is slidably installed inside the bracket through sliding plates installed on both sides and sliding grooves opened on the bracket. The rear of the locking plate is connected to the bracket through two compression springs, and the front of the locking plate has a locking slot that engages with the locking rod. The sliding plate ensures the stability of the locking plate during movement, and the compression springs provide the driving force for the locking plate to return to its original position, so that the locking process is completed automatically.

[0014] As a further optimization, the first tenon and mortise assembly includes a snap-fit ​​block and is mounted on the side panel. The snap-fit ​​block has a snap-fit ​​groove at its center, and a first limiting plate is installed on one of the opposite sides of the snap-fit ​​groove, while a limiting protrusion is installed on the other opposite side. The snap-fit ​​block is inserted into the interior of the frame through a second socket. This structure allows the first tenon and mortise assembly to be easily inserted into the interior of the frame, providing a basis for the connection with the second tenon and mortise assembly.

[0015] As a further optimization, the second tenon and mortise assembly includes a fixing block. The outer wall of the fixing block is longitudinally fitted with second limiting plates at positions corresponding to the snap-fit ​​grooves. Limiting grooves are formed at other relative positions. The limiting grooves engage with the limiting protrusions. The first and second limiting plates are misaligned and then engage with each other. The fixing block is inserted into the interior of the frame through the second socket. The engagement of the limiting grooves and the limiting protrusions provides a preliminary positioning function, and the misaligned engagement of the first and second limiting plates provides a final locking function. The dual locking mechanism ensures the reliability of the connection.

[0016] As a further optimization, the fixing component includes a vertical plate, which is installed on the frame. A sliding opening is provided in the center of the vertical plate, and a sliding frame is slidably installed inside the sliding opening. One end of the support plate is installed on the front of the sliding frame, and a fixing post is installed on the other end of the support plate. When the seat plate is placed on the frame, the fixing post clamps the outer edge of the seat plate for fixing. This fixing method is simple to operate; the seat plate can be fixed simply by pushing the sliding frame without the need for any tools.

[0017] As a further optimization, the sliding plates are controlled by a control component, which includes push rods. One end of each push rod is movably connected to the sliding plate through an opening in the sliding plate, and the other end of each push rod is provided with a connecting cylinder and movably connected thereto. The control component allows the two plates to be easily separated when the frame is aligned, ensuring that the extension rod can pass smoothly, further improving the ease of assembly.

[0018] As a further optimization, one side of the fixed support clamping plate is flat, which has a wider contact area and improves the clamping effect. The flat design increases the contact area between the fixed support and the plate, thereby improving the stability and reliability of the clamping.

[0019] This invention provides an improved, tool-free, quick-assembly structure for modular mobile shelving units with full snap-fit ​​mortise and tenon joints. Compared with the prior art, it has the following improvements and advantages: Firstly, the present invention uses a snap-fit ​​connection method to connect the frames. By engaging the female snap-fit ​​with the male snap-fit, the connection and fixation can be automatically completed simply by aligning the two frames. No screws, bolts or other fasteners are needed, and no tools are required, resulting in high assembly efficiency.

[0020] Secondly, the present invention uses a mortise and tenon connection method to connect the enclosure panel and the frame. Through the cooperation of the first mortise and tenon component and the second mortise and tenon component, the positioning of the limiting protrusion and the limiting groove, as well as the misalignment and snapping of the first limiting plate and the second limiting plate, the enclosure panel can be quickly installed and firmly fixed.

[0021] Thirdly, the present invention uses a fixed component to connect the seat plate and the frame. The sliding bracket moves within the sliding opening to drive the fixed support to clamp the seat plate. The operation is simple and intuitive, and the installation and removal of the seat plate can be completed without tools. Attached Figure Description

[0028] Please see Figures 1 to 6 This invention provides a technical solution for a tool-free quick-assembly structure of a modular mobile shelving unit with full snap-fit ​​mortise and tenon joints: The frame 1 serves as the skeleton of the mobile shelving unit, and is divided into front and rear sides. Individual frame 1s are connected to form the overall frame of the mobile shelving unit. The connection between any two frame 1s is achieved through the snap-fit ​​between a sub-buckle 3 and a female snap-fit ​​5. The female snap-fit ​​3 includes a support rod 31, a base plate 32, and a locking rod 33. The support rod 31 is connected to one of the frame 1s to be connected, extending outward from the surface of that frame 1. The other end of the support rod 31 is fitted with a base plate 32, which is a flat structural component. Locking rods 33 are installed on both sides of the bottom of the base plate 32, and are rod-shaped components extending downward from the bottom of the base plate 32. The sub-buckle 5 includes a bracket 51, a locking plate 52, a sliding plate 53, a groove 54, a compression spring 55, and a latch 56. There are two brackets 51, which are installed in a mirror image. Inside the other frame 1 that needs to be connected, the bracket 51 is fixed in the internal cavity of the frame 1. Inside the bracket 51 is a retaining plate 52, a movable plate-shaped component. The retaining plate 52 is slidably mounted inside the bracket 51 via sliding plates 53 mounted on both sides and sliding grooves 54 formed on the bracket 51. The sliding plates 53 extend outward from both sides of the retaining plate 52 and are embedded inside the sliding grooves 54, which provide a guide channel for the sliding plates 53. The rear of the retaining plate 52 is connected to the bracket 51 via two compression springs 55. One end of the compression spring 55 is fixed to the bracket 51, and the other end is fixed to the rear end face of the retaining plate 52. In its natural state, the compression springs 55 push the retaining plate 52 forward. The front end of the retaining plate 52 has a latch 56, which is an inwardly recessed slot. The shape of the latch 56 matches the shape of the latching rod 33, and the latch 56 engages with the latching rod 33. When the two frame 1s are joined, the operator pushes one frame 1 towards the other. The protruding rod 31 of the sub-clamp 3 installed on one frame 1 first contacts the surface of the other frame 1. The protruding rod 31 is inserted into the interior of the other frame 1 through the insertion hole. The protruding rod 31 continues to move inward, causing the base plate 32 to move together. During the movement, the base plate 32 reaches the position above the clamping plate 52. At this time, the clamping rod 33 at the bottom of the base plate 32 has not yet contacted the clamping plate 52. As the protruding rod 31 is further inserted, the base plate 32 passes above the clamping plate 52, and the clamping rod 33 moves with the base plate 32. When the clamping rod 33 moves to the front end position of the clamping plate 52, the clamping rod 33 begins to contact the clamping plate 52. The clamping plate 52 moves backward under the push of the clamping rod 33, causing the sliding plate 53 to slide backward inside the slide groove 54. Plate 53 moves along the guide direction of slide groove 54. This sliding process ensures the stability of the movement of clamping plate 52. When clamping plate 52 moves backward, compression spring 55 is compressed. Compression spring 55 stores elastic potential energy. When clamping rod 33 continues to move forward to the position directly above the jaw 56, clamping rod 33 no longer applies a backward pushing force to clamping plate 52. At this time, compression spring 55 releases the stored elastic potential energy and pushes clamping plate 52 forward. Clamping plate 52 drives sliding plate 53 to slide forward inside slide groove 54. Clamping plate 52 moves to the position directly below clamping rod 33. Clamping rod 33 falls into the inside of jaw 56. Clamping rod 33 and jaw 56 form a snap-fit ​​engagement. At this time, the sub-clamping buckle 3 and the female clamping buckle 5 are connected. The two frame edges 1 are also connected and fixed through the connection of sub-clamping buckle 3 and female clamping buckle 5. This connection method does not require any tools. The connection can be automatically completed by simply aligning the two frame edges 1.

[0029] In some embodiments, the enclosure panel 2 is installed on the frame 1. The enclosure panel 2 is the enclosed space of the mobile shelving unit, used to enclose the back and sides of the mobile shelving unit. The connection between the enclosure panel 2 and the frame 1 is achieved through a first tenon and mortise assembly 7 and a second tenon and mortise assembly 8. The first tenon and mortise assembly 7 is installed on the enclosure panel 2 and includes a snap-fit ​​block 71. The snap-fit ​​block 71 is a block-shaped component extending outward from the edge of the enclosure panel 2. A snap-fit ​​groove 72 is provided at the center of the snap-fit ​​block 71. The snap-fit ​​groove 72 is a through groove that passes through the snap-fit ​​block 71. A first limiting plate 73 is installed on one of the opposite sides of the snap-fit ​​groove 72. The first limiting plate 73 is a plate-shaped component extending into the groove from the inner wall of the snap-fit ​​groove 72. The first limiting plate 73 is elastic. A limiting protrusion 74 is installed on the other opposite sides of the snap-fit ​​groove 72. The limiting protrusion 74 protrudes into the groove from the inner wall of the snap-fit ​​groove 72. The protruding block component, the snap-fit ​​block 71, is inserted into the interior of the frame 1 through the second insertion port 11. The second insertion port 11 is an insertion hole opened on the frame 1. The size of the second insertion port 11 matches the size of the snap-fit ​​block 71. The second tenon assembly 8 includes a fixing block 81, which is an independent block component. The outer wall of the fixing block 81 is longitudinally mounted with a second limiting plate 83 at a position corresponding to the snap-fit ​​groove 72. The second limiting plate 83 is a plate-shaped component that extends outward from the outer wall of the fixing block 81. The second limiting plate 83 is elastic. Limiting grooves 82 are opened at other relative positions of the fixing block 81. The limiting grooves 82 are recessed inward from the outer wall of the fixing block 81. The limiting grooves 82 are snapped into the limiting protrusion 74. The first limiting plate 73 and the second limiting plate 83 are misaligned and snapped into each other. The fixing block 81 is inserted into the interior of the frame 1 through the second insertion port 11.

[0030] When connecting the enclosure 2 and the frame 1, the operator moves the enclosure 2 towards the frame 1. The enclosure 2 moves the snap-fit ​​block 71 in the first tenon and mortise assembly 7. The snap-fit ​​block 71 is inserted into the interior of the frame 1 through the second insertion port 11. After entering the interior of the frame 1, the snap-fit ​​block 71 reaches the predetermined connection position. Then, the operator inserts the fixing block 81 in the second tenon and mortise assembly 8 into the interior of the frame 1 through the first insertion port 4. The first insertion port 4 is another insertion hole on the frame 1, different from the second insertion port 11. The fixing block 81 enters the interior of the frame 1 from the first insertion port 4. The fixing block 81 continues to move inward and enters the snap-fit ​​groove 72 of the snap-fit ​​block 71. The fixing block 81 is mortised into the snap-fit ​​groove 72, fixing the snap-fit ​​block 71 inside the frame 1. During this process, the limiting protrusion 74 is inserted into the limiting groove 82. The limiting protrusion 74 is embedded into the limiting groove 82. This insertion lifts... It provides a preliminary positioning function. At the same time, the first limiting plate 73 and the second limiting plate 83 begin to contact each other. The first limiting plate 73 and the second limiting plate 83 face opposite directions. The first limiting plate 73 extends in one direction, and the second limiting plate 83 extends in the opposite direction. When the fixing block 81 continues to move into the snap-fit ​​groove 72, the first limiting plate 73 and the second limiting plate 83 press against each other. The first limiting plate 73 undergoes elastic deformation under the pressure, and the second limiting plate 83 also undergoes elastic deformation under the pressure. The two limiting plates pass through each other's positions. After passing through, the two limiting plates return to their original shapes. At this time, the two limiting plates are in a state similar to two hooks hooking each other. This state firmly connects the first tenon component 7 and the second tenon component 8 together. At this time, the enclosure 2 and the frame 1 are connected. This tenon connection method does not require the use of any tools. The connection can be completed simply by inserting the snap-fit ​​block 71 and the fixing block 81 into the corresponding slots.

[0031] In some embodiments, the seat plate 10 is mounted on the frame 1. The seat plate 10 is the part of the mobile shelving unit where items are placed. The seat plate 10 separates the internal space formed by the frame 1 and the surrounding panel 2. A fixing component 9 is mounted on the frame 1. The fixing component 9 is used to install and fix the seat plate 10. The fixing component 9 includes a vertical plate 91, which is mounted on the frame 1 and extends upward from the surface of the frame 1. A sliding opening 92 is provided at the center of the vertical plate 91. The sliding opening 92 is an elongated opening that passes through the vertical plate 91 and extends vertically. A sliding frame 95 is slidably mounted inside the sliding opening 92. The sliding frame 95 is a component that can slide up and down within the sliding opening 92. One end of a support plate 93 is mounted on the front of the sliding frame 95. The support plate 93 extends forward from the sliding frame 95. A fixing post 94 is mounted on the other end of the support plate 93. The fixing post 94 is a columnar component that extends downward from the end of the support plate 93. When the seat plate 10 is placed on the frame 1, the fixing post 94 clamps and fixes the outer edge of the seat plate 10.

[0032] When installing the base plate 10 onto the frame 1, the operator first places the base plate 10 above the frame 1, with the base plate 10 resting on the top surface of the frame 1. At this time, the outer edge of the base plate 10 is located below the fixed support column 94. Then, the operator pushes the sliding bracket 95 downward, and the sliding bracket 95 slides downward inside the sliding opening 92. The sliding bracket 95 moves along the guide direction of the sliding opening 92, and the sliding bracket 95 drives the extension plate 93 to move downward. The extension plate 93 drives the fixed support column 94 to move downward until it contacts the base plate. On the side of the seat plate 10, the fixed support column 94 continues to move downward, and the fixed support column 94 applies a clamping force to the side of the seat plate 10. The side of the seat plate 10 clamped by the fixed support column 94 is a plane. This plane design increases the contact area between the fixed support column 94 and the seat plate 10. The increase in contact area improves the clamping effect. The side of the seat plate 10 is clamped by the protruding part of the fixed support column 94. The seat plate 10 is installed on the frame 1. This fixing method does not require the use of any tools. The seat plate can be fixed by simply pushing the sliding bracket 95 downward.

[0033] In some embodiments, the control component 6 is used to separate the two clamping plates 52 when the frame 1 is mated. The function of the control component 6 is to allow the extension rod 31 to pass smoothly through the position of the clamping plate 52. The control component 6 includes a push rod 61 and a connecting cylinder 62. There are two push rods 61. One end of the two push rods 61 is movably connected to the sliding plate 53 through an opening 63 opened on the sliding plate 53. The opening 63 is a through hole opened on the sliding plate 53. One end of the push rod 61 is inserted into the interior of the opening 63. The push rod 61 and the sliding plate 53 form a movable connection relationship. The other end of the two push rods 61 is provided with a connecting cylinder 62. The connecting cylinder 62 is a cylindrical component. The other end of the two push rods 61 is movably connected to the connecting cylinder 62. The connecting cylinder 62 is located in the middle position of the two push rods 61. The connecting cylinder 62 connects the two push rods 61 together.

[0034] When the operator presses the connecting cylinder 62, the connecting cylinder 62 moves closer to the clamping plate 52. The connecting cylinder 62 drives the two push rods 61 to move, and the two push rods 61 extend to both sides from the position of the connecting cylinder 62. The push rods 61 push the sliding plate 53, and the sliding plate 53 slides to both sides along the slide groove 54 under the push of the push rods 61. The sliding plate 53 drives the clamping plate 52 to move to both sides, and the two clamping plates 52 separate under the action of the push rods 61. The separation action of the clamping plates 52 resists the thrust of the compression spring 55. At this time, the distance between the two clamping plates 52 increases. This increased distance allows the extension rod 31 to drive the seat plate 32 through, and the extension rod 31 drives the seat plate 32 to pass between the two clamping plates 52. After the extension rod 31 and the seat plate 32 have passed, the operator releases the connecting cylinder 62, and the connecting cylinder 62 returns to its original position. The push rod 61 no longer applies a pushing force to the sliding plate 53, and the compression spring 55 pushes the clamping plate 52 back to its original position. The clamping plate 52 drives the sliding plate 53 back to its original position along the slide groove 54, and the two clamping plates 52 close again. This control method makes the frame docking process smoother.

[0035] At this point, the assembly of the entire mobile shelving unit is complete. The assembly process sequentially completed the connection between the frame 1, the connection between the side panel 2 and the frame 1, and the connection between the seat 10 and the frame 1. The entire process is connected by snaps and tenons, and the connection between each component is stable and reliable. The entire installation process is convenient and quick, and can be completed without the aid of any tools.

[0036] Working process: The modular mobile shelving unit with full snap-fit ​​mortise and tenon connection provided by this invention has a tool-free quick-assembly structure. During assembly, the first step is to connect the frame 1s. The operator aligns the two frame 1s to be connected, and the extension rod 31 on one frame 1 is inserted into the interior of the other frame 1. The extension rod 31 drives the base plate 32 to pass above the clamping plate 52. The compression spring 55 pushes the clamping plate 52 to move directly below the clamping rod 33, and the clamping rod 33 engages with the slot 56. This completes the connection between the frame 1s. Then, the side panel 2 is connected to the frame 1. The operator moves the side panel 2 towards the frame 1. The side panel 2 drives the snap-fit ​​block 71 in the first mortise and tenon assembly 7 to be inserted into the interior of the frame 1 through the second insertion slot 11. Then, the operator inserts the fixing block 81 of the second tenon assembly 8 into the interior of the frame 1 through the first insertion port 4. The fixing block 81 is mortised into the interior of the snap-fit ​​groove 72. The limiting protrusion 74 is inserted into the limiting groove 82. The first limiting plate 73 and the second limiting plate 83 are misaligned and snapped together. This completes the connection between the enclosure 2 and the frame 1. Finally, the seat plate 10 is installed. The operator places the seat plate 10 on the frame 1 and then pushes the sliding frame 95 downward to slide inside the sliding port 92. The sliding frame 95 drives the extension plate 93 to move. The extension plate 93 drives the fixing pillar 94 to clamp the side of the seat plate 10. This completes the installation of the seat plate 10. The entire assembly process does not require any tools and is simple and quick to operate.
